Special elastic lamp for grinding conical surface of gear

Abstract

The invention provides a special elastic lamp for grinding the conical surface of a gear, structurally comprising a clamp body, an expansion sleeve pull rod, an elastic expansion sleeve, a workpiece positioning disc, a seal slide block, a clamp positioning disc, a pull rod and a rotary cir cylinder, wherein the longitudinal section of the clamp positioning disc is of a T shape; the pull rod is arranged at the center of the clamp positioning disc to be in sliding connection with the center through hole of the clamp positioning disc; the right end of the clamp positioning disc is connected with the clamp body by a bolt; the center of the left end of the clamp body is provided with a T-shaped concave hole; the seal slide block is arranged in the concave hole; the left end of the seal slide block is provided with an outer threaded pipe joint, and the right end of the seal slide block is provided with an inner threaded hole; the outer threaded pipe joint is connected with the right end of the pull rod through threads; and the expansion sleeve pull rod is penetrated in the center hole of the clamp body. Compared with the conventional tool for machining the conical surface of the gear, the special elastic lamp has the characteristics of high machining precision, high workpiece clamping stability, high support efficiency and the like, thus the special elastic lamp is very good in popularization and use value.

Description

Technical field: [0001] The invention relates to an elastic fixture for grinding the bevel surface of an automobile transmission gear, in particular to a special elastic fixture for grinding the bevel surface of a gear. Background technique: [0002] In recent years, the automobile industry has developed rapidly. Automobile gearboxes are very important functional parts of automobiles. The annual market demand is large. Bevel gears are key parts of automobile gearboxes. When the car is transitioning from one gear to another gear, in order to reduce the friction caused by the contact between the inner cone surface of the synchronous ring and the outer cone surface of the gear ring gear to be engaged, the friction of the cone surface makes the gear sleeve and the tooth gear to be meshed The gears are quickly synchronized to achieve soft gear shifting. The quality of the gear cone is directly related to the quality of gear shifting and the life of the gear box. The bevel gear is...

Problems solved by technology

When the car is transitioning from one gear to another gear, in order to reduce the friction caused by the contact between the inner cone surface of the synchronous ring and the outer cone surface of the gear ring gear to be engaged, the friction of the cone surface makes the gear sleeve and the tooth gear to be meshed The gears are quickly synchronized to achieve soft gear shifting. The quality of the gear cone is directly related to the quality of gear shifting and the life of the gear box. The bevel gear is the core part of the gear box, and its quality is very important. The machining quality stability of the gear bevel surface is poor, and the traditional way of passing through the mandrel is basically used for machining, which has poor machining accuracy stability and low machining efficiency
