Deep Kong Jia is versed in the technical secondary school uses the design of measure

The measurement of 3mm and 172mm dimension, produced a few difficulty. Produce to large quantities of quantities especially, and be measured in dimension go up on the work that has special demand, undertake metrical with respect to need with special measuring tool, in order to satisfy manufacturing need. If the graph is shown 1 times, workpiece is the manufacturing task that my company continues, batch is bigger, as a result of inside the special requirement that Kong Jia is versed in, measure to go to the lavatory inside hole size, we designed a bottom large special measure, hole depth reachs bore diameter with measure only special measuring tool, show cent to be narrated as follows. 1.

Large measure is by in treatment working procedure, need is deep to the bottom of blank (9.

Locate dish of bearing lever 3 pass join board 2 with measure lever 1 join is together, measure lever 1 can be inside join board chamfer slip, after the position that has adjusted it locknut 11 come back; of close fixed position bears an arm 4 two end all contain slip cover 7; through sliding 7, bear an arm 4 with rear sight the 5 framework that form can be in bearing lever 3 on slip. Its fixed can tighten solid bolt to come through sliding sleeve locking. Measure staff guage 5 on have reticle, it is the basis measures dimension to come to those who make to engrave. Measuring an arm above all 8 with measure lever the standard on the lower end mat of 1 is apart from H, the position that indicates according to measuring brachial place at this moment undertakes reticle, we call this line 0 lines. Be in next according to H dimension maximum H+ Δ is engraved make another reticle, call; of the line on limits to be engraved according to H- Δ likewise make limits get offline. Adjust before use measure lever 1 with bearing lever the 3 distances between, roll of the; in measuring lever in order to assure to be able to enter workpiece hole smoothly measures an arm 8, measuring an arm 8 with measure lever whether does finger of observation of H of distance of the standard on the lower end mat of 1 aim 0 lines, such doing is to examine whether measure has an error, if have,make through adjusting staff position its finger points to null. Can measure workpiece next with it, will measure lever to extend aperture inside, measure a head to contact hole bottom face, rotate next measure an arm, make the end panel outside workpiece of A surface contact, according to the position of pressing with a finger the circumstance can conclude, going up namely this dimension all is limits line and the workpiece between next limits lines eligible. 2.

Hole depth measures special measuring tool the graph shows workpiece bottom 1 times to need machine treatment to make sure its dimension asks (use take shape) of knife hole milling. On the issue that measures hole depth, when beginning production, we use many Cheng very depth gauge to undertake metrical, but the course carries out a proof, such not only increase investment, and the influence manufactures efficiency. To solve this problem we devised measure of deep aperture length. If pursue,3 are shown. 1.

Measure dish can measuring in sliding; makes measure process on lever, the shift after assembling its is measured dish make measure dish of B face and measure the distance between the head to measure dimension L to wait for, go up in planar G at this moment reticle (call 0 lines) , the maximum L+ Δ that measures Δ of dimension L ± according to its and Δ of L- of the least value, measuring respectively dish the reticle on plane go up namely limits line and next limits lines (notice: ?

When be being used (should proofread measure) first, will measure lever to extend the shift inside workpiece aperture to measure dish carry surface contact with workpiece, the measurement that measures lever lower end head and inside hole bottom face is conterminous touch; at this moment OK the relative position that the basis measures on lever plane 0 reticle, will decide the product is eligible. Measure lever namely 0 lines are located in measure dish on, qualification is namely between next limits lines. 3.

Deep Kong Kongjing is in with measure only bore diameter is measured in use the internal diameter watch, caliper, tool such as callipers to undertake normally, but when to the graph dimension of 4 D in showing work is measured, caused certain difficulty, devised special measure for this, the work that workpiece shows to need treatment deep opening for another kind in pursueing like graph 4() be shown, this measure by measure lever, directive lever, measure head and fixed position dish composition. 1, 2.

Prop up measure lever 9 with demonstrative lever 8 through bearing pin 7 photographs join, OK and mutual rotational; measures lever between them 9 with demonstrative lever the upright ministry of 8 contains measure a head, and two measure a head to be in same one of a plane goes up point-blank, decide size according to the graph, adjust a two intervals that measure a head to be D, according to indicating lever to indicate the position is measuring the reticle on lever (0 lines) . Adjust a two intervals that measure a head to be D+ δ and basis of D- δ ; to indicate lever to indicate respectively next the position is measuring range of the engrave on lever line and next limits lines. And measure positional H criterion by measure lever head of fixed position of 9 lower ends comes demarcate. Press next demonstrative lever handle gently when use 5 make the two span that measure a head leave be less than bore diameter, so that measure extends the aperture inside workpiece, also can prevent those who measure a head wear away at the same time. When the fixed position head that equivalent has and hole bottom surface contact, loose finger handle is slight rock measure, contact adequately with assuring to measure head and aperture wall, can judge a product next according to indicating staff position condition eligible. Indicate staff position namely going up limits line and between next limits lines. Fixed position head and measure a head to all contain hard alloy, it is to increase the wearability of measure so in order to improve its service life. This measure is mixed in reticle the standard system that makes with D+ δ and D- δ dimension respectively was used in use process. Its configuration is a product inside aperture appearance. If pursue 5 show. Can undertake to measure through it reticle is mixed proofread, especially to a few inside structure of Kong Youte different undertakes imitating like the circumstance of taper, the production of facilitating measure and proofread, measure an error in order to reduce. Another advantage of this measure can pass position of change bearing pin to change size of measure reticle limits, this ratio relation through removing L/Lx is clearly. This observes to the operation measure is very convenient, measure to what Xiaogong needs measure especially. 4.

Epilogue adopts the design of these 3 measure, outstanding performance is measuring the advantage of special measuring tool accurate, operation is convenient, decide quick, rose to machine efficiency, decreased to measure auxiliary time. In the meantime, should pointing out special measuring tool here is to decide mostly measure dimension to whether be inside deviation, can not give handlers an intuitionistic numerical value, often proofread measure with respect to requirement aborning so, prevent to cause measure an error. Be in additionally a few in be being measured actually, to a few open to question products (the circumstance that is like line ball of pressing with a finger or reticle coincide) remain need to undertake a few times metrical reaching specific and numeric; will decide whether the product is eligible with measure, prevent out of tolerance to taste flow into next line working procedure. This need special attention. CNC Milling CNC Machining
