Description

Milling and boring fixture for manipulator cover of small commercial vehicle

technical field

The utility model relates to the technical field of automobile manufacturing, in particular to a fixture for milling and boring bush holes and rocker arm holes on a manipulator cover assembly of a small commercial vehicle.

Background technique

At present, in the production of small commercial vehicle manipulator cover assemblies, the clamping method used when milling and boring the shift shaft bushing hole and the gear selection shaft bushing hole is the threaded pressure rod type. After the operator positions the manipulator cover assembly , by tightening the nut, the pressure plate under the nut is tightly pressed on the manipulator cover shell to be milled and bored. This clamping method often causes the part to shake during the processing due to insufficient clamping force, resulting in the processing size of the part. The surface roughness is too large, and it takes a long time to tighten and loosen the nut for each clamping and dismounting, which affects the production efficiency of the part processing.

Contents of the invention

The purpose of this utility model is to provide a small commercial vehicle manipulator cover milling and boring fixture, which can solve the time-consuming and labor-intensive clamping methods of the shift shaft bushing hole and gear selection shaft bushing hole of the milling and boring manipulator cover shell. Low processing efficiency and unstable clamping force cause high rate of defective products.

In order to solve the above problems, the technical solution adopted by the utility model is:

A small commercial vehicle manipulator cover milling and boring jig comprises a base, the base is provided with an oil cylinder, the piston rod of the oil cylinder is fixed with a pressure plate through a nut; the base is provided with a positioning pin.

In the above technical solution, a further solution is: there are two positioning pins.

Further: the base is also provided with a bottom plate, and the bottom plate is provided with pads.

Further: There are seven spacers, which are in the shape of cylinders.

Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

1. The utility model adopts the combination of the oil cylinder and the pressure plate to clamp the parts, the clamping speed is greatly improved, and the labor intensity of the operator is reduced;

2. The clamping method of the utility model solves the problem of high rate of unqualified parts caused by unstable clamping force.
