Description

A Fixture for Machining Curved Surfaces of Lock Hooks

technical field

The utility model relates to a tooling device for mechanical processing, in particular to a fixture for processing curved surfaces of lock hooks.

Background technique

The switching equipment of the existing high-speed railway turnouts in our country all adopts the transfer GW type hook-shaped outer locking device. GW type hook-shaped external locking device is a mechanical device that locks the point rail and the basic rail together, and it plays a very important role in the process of switch conversion and locking. GW-type hook-shaped external locking is mainly composed of locking hook, locking frame, locking rod, locking iron, point rail connecting iron, pin shaft and other main parts. The locking hook is the core of GW-type hook-shaped external locking device Forced parts.

Now, my country is in a period of rapid development of high-speed railways, and the demand for GW-type hook-shaped external locking devices is very large, and the processing of the lock hook as the core force-bearing component must ensure both quality and quantity. Due to the requirements of the design structure and installation position of the hook part, a curved surface needs to be processed on the hook part. Therefore, it is very necessary to design a set of fixtures to improve the machining accuracy and efficiency of the hook.

Contents of the invention

The purpose of the utility model is to provide a fixture for processing the curved surface of the lock hook. The fixture is simple in structure and strong in practicability. Using the fixture is convenient for clamping, reliable in processing, high in processing precision, can improve production efficiency, and ensure product quality.

The technical solution adopted by the utility model is: a fixture for processing the curved surface of the lock hook, including a clamp body 1, a cushion block 2, a positioning pin 3, a connecting long screw 4, a pressure plate 5, a support block 6, a clamping block 7, Clamping screw 8, positioning mandrel 9, connecting short screw 10 and opening pressure plate 11, clamping body 1 is fixedly installed on the processing platform of the machine tool, pad 2 and connecting long screw rod 4 are installed on clamping body 1, positioning pin 3 and The clamping block 7 is arranged on both sides of the cushion block 2 correspondingly, the pressing plate 5 is arranged on the upper end of the connecting long screw 4, the support block 6 is arranged between the pressing plate 5 and the clamping body 1, and the clamping screw 8 is installed on the clamping block 7 , the positioning mandrel 9 is arranged on the spacer 2 , the connecting short screw 10 is arranged at the center of the positioning mandrel 9 , and an opening pressure plate 11 is provided at its upper end.

Compared with the prior art, the utility model has the following beneficial effects: simple structure, strong practicability, convenient clamping, reliable processing, high processing precision, improved production efficiency and guaranteed product quality.
