Description

Double guide boring machine fixture

technical field

The invention relates to the mechanical field, in particular to a fixture for a double-guided boring machine.

Background technique

At present, the traditional fixtures of the transmission box mainly use general-purpose fixtures, but the general-purpose fixtures have problems such as clamping difficulties, low machining accuracy, and need to calibrate, which makes the processing cost of parts higher. Therefore, in order to solve the above problems in production and processing, the corresponding special fixtures are generally used for fixing, and the use of special fixtures can effectively reduce the labor intensity during work, improve labor productivity, and obtain higher processing accuracy. However, the scope of application of special fixtures is small, and it is only used to process the boring part of a certain part.

Contents of the invention

The purpose of the present invention is to provide a double-guided boring machine clamp, which has high processing precision, simple clamping method, and can process two special clamps for coaxial holes at the same time, so as to overcome the shortcomings of the prior art.

The present invention is realized in the following way: double-guided boring machine clamps include a clamp body, a cylindrical boss is provided on the top of the clamp body, a support sleeve is provided at both ends of the cylindrical boss, and a lining is provided in the support sleeve. The sleeve is provided with a boring sleeve in the bush; symmetrical support plates are provided on both sides of the top of the cylindrical boss, and symmetrical workpiece pressing devices are arranged on both sides of the cylindrical boss.

The workpiece pressing device includes a hook-shaped pressing plate. The bottom of the hook-shaped pressing plate is provided with a hook-shaped pressing plate bushing. The hook-shaped pressure plate bushing and the clamp body are provided with a transmission plate under the clamp body, and the transmission plate is connected with the bottoms of the two connecting bolts.

A bolt positioning pin is arranged between the hook-shaped pressing plate and the connecting bolt; a hook-shaped pressing plate positioning pin is arranged between the clamp body and the hook-shaped pressing plate. The bolt positioning pin can prevent the connecting bolt from rotating, and the hook-shaped pressing plate positioning pin can prevent the hook-shaped pressing plate from rotating.

A cylindrical pin and a rhombus pin are respectively arranged at both ends of the top of the cylindrical boss. Cylindrical pins and diamond pins are mainly used to locate the four degrees of freedom of movement and rotation on the horizontal plane.

Due to the adoption of the above technical scheme, compared with the prior art, the present invention adopts two guide mechanisms formed by the combination of the support sleeve, the bushing and the boring sleeve, and utilizes the two guide mechanisms to simultaneously process two different sizes of the same The shaft hole, the clamping process is simple, the processing is convenient, the processing accuracy is high, the labor intensity of the workers is reduced, and the work efficiency is improved. The invention has the advantages of simple structure, low cost and good use effect.
