Problems solved by technology

However, it is found from the process of use that the hydraulic environment changes greatly when the hydraulic chuck is fixed, and the machining accuracy is not high. On the other hand, the insecure fixation between the fixture itself and the working table of the gear turning machine will affect the machining accuracy of the ring gear

Abstract

The invention belongs to the technical field of machine tool clamps, and relates to a skiving machine expansion sleeve type clamp. The clamp comprises a clamp sleeve used for clamping a workpiece, wherein elastic chucks are arranged on the periphery of the clamp sleeve and apply clamping force pointing to the geometric center of the clamp sleeve to the clamp sleeve, a clamp body is arranged at oneend of the clamp sleeve and provides structural support for the clamp sleeve and the elastic chucks, the elastic chucks are symmetrically arranged on the periphery of the clamp sleeve along the geometric center line of the clamp sleeve, and the elastic chucks are of a cylindrical structure. According to the clamp, workpiece positioning precision is improved, workpiece deformation is prevented, then gear cutting precision is improved, the gear cutting service life of a cutter can be prolonged to a certain extent, the structure is simple, the rotational inertia of a skiving machine workbench isreduced, and it is guaranteed that a machine tool can be safely and stably stopped.

Description

technical field [0001] The invention belongs to the technical field of machine tool clamps, and relates to an expansion sleeve type clamp for gear turning machines. Background technique [0002] In the field of mechanical processing, it is usually necessary to locate and fix the workpiece to be processed, and the most common method for radial positioning and fixing of the workpiece is to use a fixture. At present, hydraulic chucks are often used to fix the ring gear when machining the gear ring. However, it is found from the process of use that the hydraulic environment changes greatly when the hydraulic chuck is fixed, and the machining accuracy is not high. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a jig with stable function, precise positioning, and firm fixation, which is used for tooth cutting of an internal ring gear. [0004] To achieve the above object, the present invention provides the following techn...
