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

The invention discloses a compensation device of a precision cam transmission mechanism. The compensation device comprises a machine body. A driving shaft is arranged on the machine body. A cam is arranged on the driving shaft. A guiding hole is formed in the machine body. A driven rod is slidably arranged by penetrating through the guiding rod. The bottom of the driven rod is attached to the cam.A convex ring is arranged on the driven rod. A first spring is arranged between the convex ring and the machine body. The machine body is provided with a closed cavity surrounding the cam from the bottom of the driven rod and the first spring. A lubrication oil channel is formed in the bottom of the closed cavity and connected with a nozzle. A first pump is arranged on the lubrication oil channel. A chip detection device is further arranged on the lubrication oil channel. The driving shaft is connected with a driving mechanism. The driving mechanism is arranged on a lifting platform. The height is controlled through a linear driving device at the bottom of the lifting platform. A control device is arranged in the machine body. According to the compensation device, abrasion loss compensation of a driven part can be conducted automatically when the cam is abraded.
Description
technical field [0001] The invention belongs to the technical field of mechanical structures, in particular to a compensation device for 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. The ca...
