Automatic regulating device of precision cam transmission mechanism

Abstract

The invention discloses an automatic regulating device of a precision cam transmission mechanism. The automatic regulating device comprises a body, a drive shaft is arranged on the body, a cam is arranged on the drive shaft, a polygonal guide hole is formed in the body, a polygonal driven rod penetrates through the polygonal guide hole in a sliding mode, and the bottom of the polygonal driven rodis attached to the cam. A bulge loop is arranged on the polygonal driven rod, a first spring is arranged between the bulge loop and the body, and a closed accommodating cavity surrounding the cam, thebottom of the polygonal driven rod and the first spring is formed in the body. A lubricating oil channel is formed in the bottom of the closed accommodating cavity and connected with a spray nozzle,a pump is arranged on the lubricating oil channel, and a chippings detection device is further arranged on the lubricating oil channel. A polygonal ejecting rod is arranged at the upper end of the polygonal driven rod in a threaded fit mode and sleeved with a turnplate, a second motor drives the turnplate to rotate through a gear, and a control device is arranged in the body. According to the automatic regulating device, compensation can be automatically made for the abrasion capacity of the driven component when the cam is abraded.

Description

technical field [0001] The invention belongs to the technical field of mechanical structures, in particular to an automatic adjustment device of a precision cam transmission mechanism. Background technique [0002] The cam mechanism is a high-level mechanism composed of three basic components: the cam, the follower and the frame. The cam is a component with a curved profile or a groove, generally a driving part, which performs constant-speed rotary motion or reciprocating linear motion. Cam mechanisms are widely used in light industry, textile, food, transportation, mechanical transmission and other fields. The displacement, speed and acceleration of the follower must be changed strictly according to the predetermined law, especially when the original mover is in continuous motion and the follower must be in intermittent motion, it is most convenient to use a cam mechanism. The motion law of the cam follower depends on the contour line of the cam or the shape of the groove...

AI Technical Summary

Problems solved by technology

[0003] During the operation of the cam mechanism, the cam and the follower will gradually wear out, resulting in a gradual change in the transmission position of the cam and the follower, resulting in a decrease in transmission accuracy and affecting the operation of the whole machine

The traditional cam mechanism has to replace the worn cam and its transmission parts when it fails to meet the accuracy requirements after a period of use, and the disassembly and assembly of the machine is inconvenient, consuming a lot of time for disassembly and assembly, and requires frequent inspection
