Description
Technical field
The present invention relates to the machine parts measurement device, be specifically related to the measurement mechanism in a kind of dark conical surface hole.
Technical background
In armament systems, particularly in the antiaircraft gun armament systems, the dark tapered hole of high precision is the inevitable inscape of antiaircraft gun ammunition emission.Such as high gun tube, the depth D that not only constitutes conical surface hole is darker, and promptly the distance of the conical surface hole and the mouth of pipe is far away, and the position accuracy demand of the dimension precision requirement in conical surface hole and correlating factor is high.This has brought great difficulty to processing and manufacturing and accurate the measurement.Conventional groove vernier measurement mechanism precision is up to 0.02mm, and the measurer manufacturing cost is high.The problem that adopts conventional groove vernier device to measure dark tapered hole workpiece existence is: 1. line width has a strong impact on the precision of measurement, and the precision of itself is also lower; 2. the three dimension coordinate measurement error is big, and is unfavorable for the measurement of process.Adopt logical no-go gage to measure,, be unfavorable for the process size Control though the scope of regulation that can measurement size does not have concrete reading.
Summary of the invention
The purpose of this invention is to provide the measurement mechanism in a kind of dark conical surface hole, its measuring accuracy is higher, and low cost of manufacture not only can be measured the workpiece of completion of processing, and can in process, measure workpiece.
The measurement mechanism in a kind of dark conical surface of the present invention hole comprises percentage gauge stand, dial gauge, standard value proof-reading block, standard gauge block, it is characterized in that:
The middle part of said percentage gauge stand is straight, left part straight up, right part straight down, the upper end of left part and the bottom of right part be all axis horizontal and the through hole that is parallel to each other respectively;
The through hole of the upper end of one spring-backed quill and said percentage gauge stand left part is connected, and the table pin of said dial gauge cooperates with this spring-backed quill, and fastening through set nut, and the measuring head of said dial gauge contacts with the right-hand member of said standard value proof-reading block;
One prelocalization cover cooperates with the middle part of said standard gauge block, and the periphery of this prelocalization cover contacts with the inner walls of deep holes of measured workpiece; The through hole of the bottom of the right part of said standard gauge block and said percentage gauge stand right part is connected, and fastening through nut; The left part of said standard gauge block contacts with the conical surface hole of measured workpiece, and the right side contacts with the left end of said standard value proof-reading block.
The measurement mechanism in described a kind of dark conical surface hole, its said standard value proof-reading block is flat and the left part bends downwards.
The measurement mechanism in described a kind of dark conical surface hole, the left part of its said standard gauge block is tapered, and tapering is consistent with the tapering of measuring workpieces.
The measurement in dark conical surface hole be with the check and correction distance B of standard gauge block and measured workpiece compare measurement apart from dimension D (being the degree of depth in conical surface hole), and the measurement of comparison result is calculated, know conical surface hole dimension characteristic detection method.
Beneficial effect of the present invention: can realize the accurate measurement of the special dark tapered hole of high precision; Not measured the place limits; Can in process, accurately measure workpiece, the reflection workpiece is processed the removal surplus really, reaches the dimensional accuracy in special dark conical surface hole and the measurement requirement of positional precision; Improve the workpiece processing accepted product percentage, cut down finished cost; Compare with the measurement of groove mode, measuring accuracy improves 5 times, and cost descends 10%.The reason that manufacturing cost is lower is: the core of this method is the measurement of comparison technology, and standard gauge block only needs tapering consistent with measured workpiece, and precision prescribed does not need high especially, only gets measured value and gets final product; The D value of standard value proof-reading block (being the depth value in conical surface hole) precision prescribed does not need high especially yet, only gets measured value and gets final product.The user calculates with the standard correlative value of measured workpiece and can use according to both measured values.Therefore, the accurate measurement method of the dark tapered hole of high precision and device thereof have good application prospects.
