Description

A tooling fixture for processing threaded holes of lock hook parts

technical field

The utility model relates to a tooling device for mechanical processing, in particular to a tooling fixture for processing threaded holes of lock hook parts.

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 parts, two M6 threaded holes with an angle of 20° need to be processed on the hook parts. The hook parts are one of the leading products in the production parts of our factory, and the monthly production workload accounts for 40 More than %, now using the dividing head for clamping and positioning, there are many operating procedures and low production efficiency. Therefore, it is very necessary to design a set of tooling fixtures to improve processing efficiency.

Contents of the invention

The purpose of the utility model is to solve the problems existing in the prior art, and provide a fixture for processing threaded holes of lock hook parts, which has a simple and practical structure, simple and convenient operation, and can improve production efficiency.

The technical scheme adopted by the utility model is: a tooling fixture for processing threaded holes of lock hook parts, including a clamp body 1, an adjustable cushion block 2, a positioning mandrel 3, a pillar 4, a pressing plate 5 and a bolt 6, The clamp body 1 is in an "L" shape, and the bottom surface is provided with a connection hole connected with the machine tool table. The positioning mandrel 3 is installed on the upper end of the clamp body 1 side, and the adjustable spacer 2 is installed on the clamp body 1 side through the bolt 6. The lower end, the pillar 4 is installed on one side of the side of the clamp body 1, the pressing plate 5 is installed on the pillar 4 through fastening bolts, and is in close contact with the lock hook parts, and the adjustable pad 2 is a four-sided cylinder, which is set There are two reference surfaces 21 and two positioning surfaces 22, and a rotating fastening hole 23 is provided at the center. The two reference surfaces 21 and the two positioning surfaces 22 are corresponding surfaces. Face 22 is in contact with the shackle part.

Compared with the prior art, the utility model has the following beneficial effects: the structure is simple and practical, the operation is simple and convenient, and the production efficiency can be improved.

detailed description

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a tooling fixture for processing threaded holes of lock hook parts, including a clamp body 1, an adjustable cushion block 2, a positioning mandrel 3, a pillar 4, a pressing The plate 5 and the bolt 6, the clamp body 1 is "L" shape, and two Ф13 connection holes connected with the machine table are arranged on the bottom surface, the positioning mandrel 3 is installed on the upper end of the side of the clamp body 1, and the adjustable spacer 2 The bolt 6 is installed on the lower end of the side of the clamp body 1, the pillar 4 is installed on one side of the clamp body 1, the pressing plate 5 is installed on the pillar 4 through the fastening bolt, and is in close contact with the lock hook part, and the adjustable pad Block 2 is a four-sided cylinder, which is provided with two reference surfaces 21 and two positioning surfaces 22, and a Ф11 rotating fastening hole 23 is provided in the center, and the two reference surfaces 21 and two positioning surfaces 22 are corresponding surfaces , The datum surface 21 is in contact with the machine table surface, and the positioning surface 22 is in contact with the locking hook parts.

When in use, fix the fixture on the working table of the drilling machine, set the locking hook parts on the positioning mandrel, and make contact with the positioning surface of the adjustable pad, tighten the fastening bolts, press the pressure plate, and process One M6 threaded hole, after processing a batch, loosen the bolt, rotate and replace the adjustable pad, tighten the bolt, then set the locking hook part on the positioning mandrel, and make contact with the positioning surface of the adjustable pad, tighten Tighten the bolts, press the pressure plate, and process another M6 threaded hole. Two positionings can be realized by changing the adjustable pad, which is convenient for operation and high in production efficiency.
