Locking mechanism for rotating of pneumatic index plate and using method of locking mechanism

Abstract

The invention relates to the field of pneumatic index plates, in particular to a locking mechanism for rotating of a pneumatic index plate and a using method of the locking mechanism. The locking mechanism comprises a base, a supporting column is fixed to the base, the supporting column is arranged in the vertical direction, the index plate is arranged at the upper end of the supporting column, the center of the bottom face of the index plate is rotationally connected to the supporting column through a rotary disc bearing fixed shaft, a decelerating mechanism is arranged on the bottom face of the index plate, a locking mechanism body is arranged on the supporting column, the decelerating mechanism can be in transmission connection with the locking mechanism body, a cooling mechanism is arranged on the locking mechanism body, and the locking mechanism body is in transmission connection with the cooling mechanism. According to the locking mechanism for rotating of the pneumatic index plate and the using method of the locking mechanism, the index plate is decelerated through the decelerating mechanism in the stopping process of the index plate, deceleration of the index plate is achieved, impact of inertia force on a toothed plate when the index plate is stopped is reduced, the service life is prolonged, the locking mechanism body is driven by the decelerating mechanism to lock the index plate when the index plate is kept static, and the index plate is ensured to be locked and not to rotate when being stopped.

Description

technical field [0001] The invention relates to the field of pneumatic indexing discs, in particular to a locking mechanism for rotating a pneumatic indexing disc and a method for using the same. Background technique [0002] The indexing plate is a machine tool accessory that clamps the workpiece on the chuck or between two centers, and makes it rotate, index and position. The indexing table is mainly used in milling machines, and is also commonly used in drilling machines and surface grinders. It can also be placed on the platform for fitters to mark lines. [0003] Generally speaking, after the pneumatic indexing plate is installed on the workpiece, the workpiece is processed. When the pneumatic indexing plate is stopped, the moment of inertia is relatively large, especially when installing heavier or larger workpieces, the moment of inertia is even greater. , it is easy to exert a large impact on the stopper during the stop operation, resulting in a reduction in the lif...

[0003] Generally speaking, after the pneumatic indexing plate is installed on the workpiece, the workpiece is processed. When the pneumatic indexing plate is stopped, the moment of inertia is relatively large, especially when installing heavier or larger workpieces, the moment of inertia is even greater. , it is easy to exert a large impact on the stopper during the stop operation, resulting in a reduction in the life of the stopper and increasing the cost of use, and the existing pneumatic indexing table cannot be locked when it is stopped, causing the workpiece to be separated during installation. The dial rotates, which is not convenient for fixing the workpiece
