Drilling jig for cylinder block of brake hydraulic cylinder

Abstract

The invention relates to a drilling jig for a cylinder body of a brake hydraulic cylinder, which comprises a base, a right support seat, a right clamping handle, a positioning shaft, a drill sleeve, fastening bolts, a cover plate, a left support seat and a left clamping handle. The middle part of the base is provided with a support platform, and the support platform is provided with strip grooves, and the left and right ends of the base are provided with bolt grooves. The right support base is fixedly connected with the base through bolts, and the right clamping handle is screwed with the right support base. The middle part of the positioning shaft is provided with two shaft shoulders, and a trimming shaft is arranged between the two shaft shoulders, and the trimming shaft is clamped in the bar-shaped groove of the supporting platform. The cover plate is connected with the support platform through bolts. The fastening bolts are screwed into the threaded holes of the cover plate. The left support base is fixedly connected with the base through bolts, and the left clamping handle is screwed with the left support base. The invention has the advantages of reasonable structure, high work efficiency, etc., and can clamp two brake hydraulic cylinder bodies at one time, greatly improving the clamping efficiency.

Description

technical field [0001] The invention relates to the technical field of production and processing of hydraulic cylinders, in particular to a drilling jig for cylinder blocks of brake hydraulic cylinders. Background technique [0002] The brake pump is composed of various parts, among which the brake hydraulic cylinder is an indispensable part. The brake hydraulic cylinder includes parts such as cylinder body, piston and sealing ring. In the process of processing the hydraulic cylinder, the hydraulic cylinder Body fabrication is the most critical step. The cylinder body of the hydraulic cylinder is firstly shaped by casting, then the piston hole of the cylinder body is processed, and then the hole of the lug is completed by a drilling machine. The machining accuracy of the lug directly affects the installation of the hydraulic cylinder. Positioning accuracy, if the installation and positioning of the hydraulic cylinder is inaccurate, it may cause the interruption of the worki...

AI Technical Summary

Problems solved by technology

The cylinder body of the hydraulic cylinder is firstly shaped by casting, then the piston hole of the cylinder body is processed, and then the hole of the lug is completed by a drilling machine. The machining accuracy of the lug directly affects the installation of the hydraulic cylinder. Positioning accuracy, if the installation and positioning of the hydraulic cylinder is inaccurate, it may cause the interruption of the working process of the brake pump, which will inevitably lead to the ineffective braking effect of the car, and in severe cases, it will cause brake failure, with disastrous consequences

The traditional cylinder lug hole is clamped by a drill fixture to ensure its machining accuracy, but it can only be clamped one at a time, which seriously affects the work efficiency. Due to the increasing number of cars, The demand for brake hydraulic cylinders continues to increase, so the existing clamping method must be changed, and a drilling jig with high work efficiency, high clamping precision and simple operation is urgently needed
