Abstract

The amount of the invention relates to jig manufacturing and repair the grinding machinery of thick smooth grinding measuring claw working face.Can form by the amount of changeing jig positioning clamping device by a transmission mechanism, lapping device and two kinds.Be contained in the positioning clamping device on the support, grinding, transmission decelerating device by timer-operated motor, drive guide wheel through the two-stage gear reduction and rotate, and cursor slide and bistrique and mill are done reciprocating linear motion; Simultaneously, promote ratchet mechanism, stir mill and do rotatablely moving of intermittence by the projection on the guide wheel.These three kinds of motions are synthesized, and just form the most reasonably * the shape grinding trajectory.Thereby grinding effect and technology acuracy have been improved effectively.

Description

Gauge grinder

The present invention relates to the manufacturing of measurement instrument and repair special-purpose grinding machinery, be used for the grinding of the inside and outside measuring claw working face of all size outside micrometer and slide measure and calliper equivalent jig.

Known amount jig is mechanical industrial and mineral enterprises and institutions amount jigs the most commonly used, the reparation of its inside and outside measuring claw working face, and the mill that adopts is seen shown in Figure 5 usually.This mill working face a and b are to hold outer round surface C by hand by the people to realize grinding.Not only take a lot of work, time-consuming, abrasive material consumption is many, labour intensity is big, and is difficult to reach the quality standard requirement of national verification rules.

The objective of the invention is to be to design the motor-driven mill of the inside and outside measuring claw of a kind of amount of being applicable to jig, reduce labor intensity, reduce abrasive material consumption, improve and grind effect and grinding precision.

The technology of the present invention solution is: will measure jig and be contained on the positioning clamping device in the support dovetail groove.With the motor is active force, through the two-stage gear reduction, drives the guide wheel rotation, make the bearing pin that is contained on the cursor slide and with the rolling cover that matches, under the effect of guide wheel sliding tray, promote cursor slide and do reciprocating linear motion with bistrique that is connected with cursor slide and mill; Simultaneously, push the ratchet mechanism that is contained in cursor slide and the bistrique housing, stir the mill that is contained on the bistrique and do intermittently to rotatablely move by the projection on the guide wheel.Go round and begin again, this three kinds of motions synthetic just formed best * shape grinding trajectory.Mill working face and polished measuring staff working face rotate the feed grinding amount voluntarily under the effect of frictional force.Be provided with the abrasive material storage recess on the mill working face, can realize replenishing voluntarily abrasive material, store collected residue abrasive material reduces abrasive material consumption simultaneously.Milling time can be selected timer control motor according to the size of amount jig wearing and tearing deviation.Improved grinding precision effectively by above measure, effect improves more than 20 times than hand lapping.

Accompanying drawing is an one embodiment of the invention, describes in further detail with regard to feature of the present invention below in conjunction with accompanying drawing:

Fig. 1 is an assembly structure front view of the present invention

Fig. 2 is the vertical view of Fig. 1;
