Clamp for grinding gear

Abstract

The invention discloses a clamp for grinding a gear. The clamp comprises a fixed handle, a base, an explosion cutting sleeve and a supporting column, wherein the fixed handle which is a solid iron column is fixedly connected to a three jaw chuck of a lathe; the base is fixedly connected to the outer end of the fixed handle; the explosion cutting sleeve which is cylindrical is fixedly connected to the base; the front end of the explosion cutting sleeve is an arc-shaped opening and the middle part thereof is an arc-shaped bump, and a plurality of openings are formed on the side face of the explosion cutting sleeve; the supporting column is mounted on a tailstock of the lathe; the explosion cutting sleeve is made of a steel material which is high in toughness; and the diameter of the supporting column is greater than that of the opening at the front end of the explosion cutting sleeve. The clamp disclosed by the invention has the beneficial effects that the clamp is simple in structure, reasonable in design, good in fixing effect, convenient to detach the gear and easy to popularize and use.

Description

technical field [0001] The invention relates to the technical field of gear production and processing, in particular to a fixture for grinding gears. Background technique [0002] In industrial production, gears are widely used. After heat treatment, the end face of the gear is turned. The purpose of frequent turning of the end face is to deburr or ensure the flatness of the end face. Due to the large gear, the three-jaw chuck that comes with the lathe is very inconvenient to use. At the same time During the clamping process, the upper surface of the gear is not flat enough, and the clamping by the three-jaw chuck will affect the machining accuracy. If the clamping is not ideal, the lathe will even cut the end surface into a bevel, which will cause the gear to be scrapped. [0003] However, the existing technology has adopted different fixtures. These fixtures ensure the precision of machining, but the speed of changing gears is very slow, and the operation is cumbersome to...

Problems solved by technology

After heat treatment, the end face of the gear is turned. The purpose of frequent turning of the end face is to deburr or ensure the flatness of the end face. Due to the large gear, the three-jaw chuck that comes with the lathe is very inconvenient to use. At the same time During the clamping process, because the upper surface of the gear is not smooth enough, the clamping by the three-jaw chuck will affect the machining accuracy. If the clamping is not ideal, the lathe will even cut the end surface into a bevel, which will cause the gear to be scrapped

[0003] However, the existing technology has adopted different fixtures. These fixtures ensure the accuracy of machining, but the speed of changing gears is very slow, and the operation is troublesome to use, which affects the benefits of the enterprise.
