Clamp for oil atomizer body end face grinding procedure

Abstract

The invention discloses a clamp for an oil atomizer body end face grinding procedure. The clamp is characterized in that the clamp comprises a locating disc component, a meteor disc and a clamping component, the locating disc component comprises a locating disc and at least four short locating pins connected with the locating disc in a threaded mode, and the end faces of the short locating pins are located on the same plane; the clamping component comprises H-shaped locating bocks, first clamping bocks and second clamping blocks, and the first clamping blocks and the second clamping blocks are distributed on the two sides of the locating blocks, in a V shape and fixed on the two sides of the locating blocks through bolts. The clamp has the advantages that the mode that oil atomizer body end faces are located and the V-shaped clamping blocks are used for clamping oil atomizer bodies is adopted, locating swivel nuts are omitted, operation is more convenient, locating is more accurate, size consistency is good, the number of workpieces clamped at a time is multiplied, production efficiency is greatly improved, quality of the procedure is improved, and subsequent machining quality is better guaranteed.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture suitable for grinding and grinding the end face of a fuel injector body. Background technique [0002] In the end face grinding and grinding process of the injector body, the end face grinding meteor disc will be used. The existing end face grinding meteor disc mainly fixes the injector body through the positioning screw sleeve and the baffle, that is, the injector body 1 is screwed into the positioning screw sleeve 2 one by one, screwed to the bottom, and fastened with screws (such as figure 1 shown), and then put the positioning screw 2 with the injector body 1 into the meteor disk 3 (such as figure 2 As shown), press the injector body 1 with the upper baffle plate 4 of the meteor disk 3 (such as image 3 As shown), the distance from the end face to the bottom of the spring hole is determined by controlling the amount of wear through the positioning of the injector body 1 shoulder blad...

AI Technical Summary

Problems solved by technology

[0003] However, this positioning method is often cumbersome to operate, and the number of fuel injector bodies 1 clamped at one time is small ( figure 2 The figure shows that 6 injector bodies are clamped at one time), and the distance from the injector body 1 shoulder blade to the end face is relatively large (such as figure 1 As shown, L in the figure is the distance from the shoulder blade to the end face), which makes it impossible to control the consistency of its size, greatly reduces the production efficiency, and makes it difficult to guarantee the quality of this process, thus affecting subsequent processing
