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 an expansion sleeve type clamp for a gear turning machine, including a clamp sleeve, the clamp sleeve is used to clamp a workpiece; an elastic chuck is arranged on the outer periphery of the clamp sleeve, and the elastic chuck is The clamp sleeve exerts a clamping force directed to its geometric center; a clamp body is provided at one end of the clamp sleeve, and the clamp body provides structural support for the clamp sleeve and the elastic collet. The elastic collets are arranged symmetrically on the outer periphery of the clamp sleeve along the geometric center line thereof, and the elastic collets are in a cylindrical structure. The invention improves the positioning accuracy of the workpiece, prevents the deformation of the workpiece, and further improves the gear cutting accuracy, which can prolong the cutting life of the tool to a certain extent, and has a simple structure and reduces the moment of inertia of the gear turning machine workbench, ensuring that the machine tool can be stopped safely and smoothly .

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...
