Tooth milling clamp for gear clutch with even number of straight teeth

Abstract

The invention relates to a tooth milling clamp for a gear clutch with even number of straight teeth. The tooth milling clamp comprises a clamp body, a peripheral locating mechanism, an axial locating mechanism and pressing plate compressing mechanisms, which are mounted on a milling machine worktable. The peripheral locating mechanism comprises a dividing disc, a connecting disc at the upper end of the dividing disc, and a spanner movably penetrating through a rectangular hole in the surface of the clamp body. Locating sleeves, which are as many as teeth of the clutch, are evenly distributed on the dividing disc in the circumferential direction, a ball pin bulb capable of elastically moving up and down on the clamp body is matched in the corresponding locating sleeve, the axial locating mechanism comprises a core shaft used for locating a workpiece and a large gasket, the pressing plate compressing mechanism comprises a double-end bolt in threaded connection with the connecting disc, a support bolt and a pressing plate, and the two ends of the workpiece are clamped between the pressing plate and the large gasket. The tooth milling clamp ensures that the side surface of the workpiece tooth of the machined clutch installed on the clamp is a bevel angle; and the locating is accurate, the clamping is fast, the equal division accuracy and the machining accuracy of the equal-division even clutch are guaranteed, the machining of even teeth of the clutch at the two ends is completed, and the machining efficiency is high.

Description

technical field [0001] The invention relates to a tooth milling fixture for an even-numbered straight-tooth clutch of a gear, which belongs to the fixture of a machine tool for processing mechanical parts. Background technique [0002] The jaw clutch is composed of two half clutches with teeth on the end faces, and the torque is transmitted by the mutual engagement of the teeth. It is widely used in mass-produced transmission machinery such as automobiles and tractors. The use of high-efficiency machine tool fixtures can reduce production costs and produce significant economic benefits. The commonly used tooth type of jaw clutches is rectangular, and the number of teeth is mostly odd, and occasionally there are even numbers. When the number of teeth is odd, such as 3, there must be no teeth on the opposite side of the axis of the tooth. Using a horizontal milling machine disc milling cutter can directly mill through to the opposite side to improve efficiency, so it is widel...

Problems solved by technology

The bigger difficulty is that after milling one side of the tooth, the workpiece needs to be repositioned when milling the other side. How to ensure the machining accuracy and fast positioning has always been a difficult problem.
