Fast locking device special for spline connection disc

Abstract

The invention relates to a fast locking device special for a spline connection disc. The fast locking device comprises a mounting disc, telescopic adjusting blocks, a screw rod, a locking screw and abaffle; the telescopic adjusting blocks are evenly distributed on the front face of the mounting disc in the circumferential direction, the screw rod is arranged on the axis of the mounting disc in acoaxially-penetrating manner, the locking screw is coaxially mounted on the front end of the screw rod, the baffle is round, an inserting groove is formed in the baffle in the radial direction, the baffle is coaxially arranged on the locking screw through the inserting groove, and the fast locking device special for the spline connection disc is scientific in design, reasonable in structure, convenient to use, and high in practicability. Through the device, the clamping difficulty can be reduced, work efficiency is improved, machining precision is improved, the rejection rate is reduced, in addition, the device is wide in application range, and the device is suitable for machining of two different specifications of spline connection discs.

Description

technical field [0001] The invention relates to a clamping tool in the technical field of spline connection disk production and processing, in particular to a special fast locking device for a spline connection disk. Background technique [0002] As shown in FIG. 5 , it is a schematic diagram of the structure of the spline connection plate, and its overall structure is approximately frustum-shaped. During the processing of the spline connection plate, there is a process of finely grinding the outer diameter of the small end. At present, there is no special fixture for clamping the workpiece. Workers usually use simple tools such as pressure plates and screws to clamp and fix the workpiece, which results in low clamping accuracy of the workpiece and affects its processing accuracy. Since this workpiece requires high machining accuracy when finely grinding the outer diameter of the small end, it can only rely on the technical level of the staff to make up for the error of too...

Problems solved by technology

At present, there is no special fixture to clamp the workpiece, and the staff usually use simple tools such as pressure plates and screws to clamp and fix the workpiece, which results in low clamping accuracy of the workpiece and affects its processing accuracy

Since this workpiece requires high machining accuracy when finely grinding the outer diameter of the small end, it can only rely on the technical level of the staff to make up for the error of tooling and clamping. The technical level and production experience of the staff are relatively high. It is difficult to meet the requirements, which not only increases the labor cost of the enterprise, but also leads to slow production speed and low work efficiency, and is also prone to waste products, increasing the use of raw materials
