Positioning tool for multiple stations for machining of guide sleeve

Abstract

The invention discloses a positioning tool for multiple stations for machining of a guide sleeve. The positioning tool comprises a fixing plate, outer wall clamping mechanisms and inner hole clampingmechanisms, wherein the fixing plate is horizontally placed, and a stepping motor for driving the fixing plate to rotate is arranged at the bottom of the fixing plate; and a plurality of rotary discsare arranged on the fixing plate and distributed on the fixing plate in an annular array manner. The positioning tool is characterized in that each rotary disc is fixedly provided with the corresponding outer wall clamping mechanism, and the outer wall clamping mechanisms are close to the edges of the rotary discs; the outer walls of workpieces are clamped through the outer wall clamping mechanisms; the inner hole clamping mechanisms are arranged at the centers of the rotary discs, and inner holes of the workpieces are clamped through the inner hole clamping mechanisms; and the guide sleeve issequentially clamped through the outer wall clamping mechanisms and the inner hole clamping mechanisms, and therefore the outer wall and through holes of the guide sleeve are machined at the same time through equipment, and the precision of guide holes is guaranteed.

Description

technical field [0001] The invention relates to the field of hydraulic equipment processing equipment, in particular to a positioning tool for processing multiple stations of a guide sleeve. Background technique [0002] The current guide sleeve is a part placed inside the hydraulic cylinder. The coaxiality of the piston rod and the hydraulic cylinder is guaranteed through the guide sleeve. In this way, the accuracy of the inner hole and the outer wall of the guide sleeve must be ensured during processing. In this way In order to ensure that the guide sleeve cooperates with the hydraulic cylinder and piston rod; [0003] When the existing guide sleeve is processed, it needs to be processed at each position of the guide sleeve, that is, when processing each station of the guide sleeve, it needs to be processed and clamped multiple times. There is no guarantee that there will be no positioning errors during the process. In this way, during processing, the accuracy will fluctu...

Problems solved by technology

[0003] When the existing guide sleeve is processed, it needs to be processed at each position of the guide sleeve, that is, when processing each station of the guide sleeve, it needs to be processed and clamped multiple times. There is no guarantee that there will be no positioning errors during the process, so that when processing, the accuracy will fluctuate greatly due to positioning errors, so the accuracy of the guide sleeve cannot be guaranteed after the guide sleeve is processed
