Spherical face and inner hole clamp for machining planetary teeth

Abstract

The invention discloses a spherical face and inner hole clamp for machining planetary teeth. The clamp comprises a pull rod, a clamp body is arranged on one side of the pull rod, a push plate is arranged inside the clamp body, three limiting blocks are uniformly arranged at one end, far away from the pull rod, of the clamp body around the outer side of the clamp body, the limiting blocks are connected with the push plate through sliding blocks, an installation seat is arranged at one end, far away from the pull rod, of the clamp body, three hook head pressing plates are uniformly arranged on one side, far away from the pull rod, of the clamp body and around the outer side of the installation seat, and the hook head pressing plates are connected with the installation seat through springs. The clamp has the beneficial effects that the installation seat is matched with the hook head pressing plates, so that when the clamp is used for machining the planetary teeth of the same type, the installation seat and the hook head pressing plates can be directly replaced to machine the planetary teeth of the same type, and the clamp is convenient to use for workers.

Description

technical field [0001] The invention relates to the field of jigs for machining spherical inner holes of planetary gears, in particular to a jig for machining spherical inner holes of planetary gears. Background technique [0002] Fixture refers to the device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position to accept construction or inspection. It is also called fixture. In a broad sense, any process in the process is used to quickly and The device that installs the workpiece conveniently and safely can be called a fixture. The fixture is usually composed of a positioning element (determining the correct position of the workpiece in the fixture), a clamping device, and a tool setting guide element (determining the relative position or guiding of the tool and the workpiece) Tool direction), indexing device (to enable the workpiece to complete the processing of several stations in one installation, there ar...

Problems solved by technology

[0003] In the production and processing of automotive gears, straight bevel planetary gears such as Image 6 As shown, the inner hole and spherical surface are processed, the inner hole is processed separately, and then the inner hole is positioned to process the spherical surface. Two equipments are required for production, one inner hole grinder and one outer cylindrical grinder. When processing the spherical surface, the center distance of the spherical surface Dimensional instability, processing accuracy and reliability of the production process; have a greater impact on the production cost and production time of the enterprise

At the same time, in the traditional fixture, the planetary gear is processed by setting the cage, the positioning column and the clamping block. Although this method can fix the planetary gear well, it cannot be fixed when the device is working. Different types of planetary gears of the same type are processed, which is inconvenient to use
