Device used for machining end face cam

Abstract

The invention discloses a device used for machining an end face cam. By means of the device, the position of a working table can be adjusted. The device comprises a worm shaft driven through power. The worm shaft drives a worm wheel shaft to rotate through a worm and a worm wheel. The worm wheel shaft is sued for driving the end face cam to rotate. A driving gear is arranged on the worm shaft and drives a transverse lead screw to rotate through driven gears which are sequentially meshed with one another. The transverse lead screw is connected with a nut in a threaded manner. The nut is fixed to the bottom of a transverse slide plate which is guided in the transverse direction through a slide block on the upper portion of a vertical slide plate. The vertical slide plate is arranged on a vertical guide rail. A limiting block abutting against the side face of a longitudinal slide plate is fixed to the end of the transverse lead screw. A guide column is fixed to the upper portion of the transverse slide plate and located in an arc-shaped groove of an inclined ruler. The arc top of the arc-shaped groove faces one side of the end face cam. The inclined ruler is located on the upper portion of the transverse slide plate. The side, away from the end face cam, of the inclined ruler is hinged to one end of a threaded rod which is connected to a horizontal base in a threaded manner. A handle is arranged at the other end of the threaded rod.

Description

technical field [0001] The invention relates to a device for machining end cams. Background technique [0002] Cam is a common part of various mechanical equipment. There are many types of cams, disc cams and cylindrical cams are commonly used. The end cam is a kind of cylindrical cam. The cam whose profile curve is located at the end of the cylinder and rotates around its axis is called an end cam. Existing devices for machining end cam curves usually use a three-jaw chuck for positioning and clamping. The three-jaw chuck has a complex structure and high cost; However, if the worktable has a position deviation during long-term work, the feed is not in place or the feed is excessive, it cannot be adjusted independently, which will affect the processing of the end cam. Contents of the invention [0003] The present invention intends to provide a device for processing end face cams which can adjust the position of the workbench. [0004] The device for processing the end ...
