Claw disc clamp for gear finish machining

Abstract

The invention discloses a claw disc clamp for gear finish machining and belongs to the field of mechanical engineering application. The claw disc clamp comprises a clamp head, a disc-shaped base with cylindrical bosses arranged on the two faces is arranged at the left end of the clamp head, a cylindrical main shaft with threads is arranged at the right end of the clamp head, and a disc-shaped cushion plate is installed on the cylindrical boss on the right face. The main shaft is provided with a first elastic clamp sleeve and a second elastic clamp sleeve, and the thread part is connected with a nut padded with a pad. The claw disc clamp aims at overcoming the defects that in the gear machining process, a clamp is insufficient in strength and complex in structure, the positioning precision cannot meet the machining requirement, and the demand for quick production cannot be met; the claw disc clamp is simple in structure, low in manufacturing cost, convenient to demount, capable of ensuing the gear machining precision and capable of achieving mass quick production of workpieces of different dimensions through replacement of the elastic clamping sleeves of the corresponding dimensions and cushion plates of the corresponding dimensions.

Description

technical field [0001] The invention belongs to the application field of mechanical engineering, and in particular relates to a claw disc fixture used for gear finishing. Background technique [0002] A fixture is a device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position for construction or inspection. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. Such as welding jigs, hobbing jigs, assembly jigs, machine tool jigs, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as the size, geometric shape, and position accuracy with other surfaces specified in the drawing, the workpiece must be installed (positioned) and clamped (clamped) before proce...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a fixture for gear processing, in order to solve the shortcomings of insufficient strength, complex structure, positioning accuracy of the gear fixture and the inability to meet the needs of rapid production in the process of gear processing, and to provide a structure Simple, low cost, easy to disassemble, and ensure the machining accuracy of gears. For workpieces of different sizes, just replace the elastic jacket (6) and backing plate (3) of the corresponding size with the fixture that can be mass-produced quickly
