Self-adaptive grease injection device for mechanical arm transmission bearing

Abstract

The invention relates to the technical field of mechanical arms, and discloses a self-adaptive grease injection device for a mechanical arm transmission bearing. The self-adaptive grease injection device comprises a large arm, the top end of the large arm is movably connected with a hinge connecting shaft, the periphery of the hinge connecting shaft is fixedly sleeved with a grease injection ring, and the right end of the hinge connecting shaft is fixedly connected with a small arm; and a hydraulic rod extending to the small arm is movably hinged to the right end of the large arm, an adjusting gear is rotationally connected to the surface of the large arm, and a rack extending to the adjusting gear is movably connected to the end, close to the small arm, of the hydraulic rod. According to the self-adaptive grease injection device for the mechanical arm transmission bearing, the rack is driven by the hydraulic rod to enable the adjusting gear to rotate in a reciprocating manner, so that an air bag ring intermittently extracts trace grease into the grease injection ring through a grease conveying pipe, and the bearing is uniformly lubricated; and therefore, the convenience of grease injection operation and the stability of equipment operation are effectively improved, and the situation that a hydraulic mechanism operates for a long time to collect heat is avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to an adaptive grease injection device for a mechanical arm transmission bearing. Background technique [0002] At present, due to the application of intelligent manufacturing technology in the field of industrial manipulators is becoming more and more mature, most of the processing and manufacturing industries have chosen manipulators to replace manual operations to complete more precise operations. The arm needs to continue a certain reciprocating action at a high speed for a long time, which will cause the corresponding transmission bearing to wear a lot. The traditional maintenance method is to add lubricating grease by manual grease injection, but this method The operation convenience of the machine is low, the amount and time of adding the grease cannot be precisely controlled, and the uniform and full contact between the grease and the internal parts of the bearing ca...

Problems solved by technology

[0002] At present, due to the application of intelligent manufacturing technology in the field of industrial manipulators is becoming more and more mature, most of the processing and manufacturing industries have chosen manipulators to replace manual operations to complete more precise operations. The arm needs to continue a certain reciprocating action at a high speed for a long time, which will cause the corresponding transmission bearing to wear a lot. The traditional maintenance method is to add lubricating grease by manual grease injection, but this method The operation convenience of the machine is low, the amount and time of adding the grease cannot be precisely controlled, and the uniform and full contact between the grease and the internal parts of the bearing cannot be guaranteed, which will affect the stability of the equipment operation in the later stage. In addition, because the mechanical arm needs to rely on the corresponding hydraulic pressure The internal hydraulic oil temperature will rise sharply after the hydraulic mechanism runs for a long time, which will affect its corresponding working efficiency and service life

[0003] Aiming at the deficiencies of the prior art, the present invention provides an adaptive grease injection device for the transmission bearing of the mechanical arm, which effectively improves the convenience of the grease injection operation and the stability of the equipment operation, and effectively avoids the long-term maintenance of the hydraulic mechanism. The advantage of heat collection during operation solves the problem of the low convenience of manual grease injection during the use of general mechanical arm transmission bearings and the inability to accurately control the amount and time of grease injection, which in turn affects the stability of equipment operation. The hydraulic mechanism is prone to heat collection problems when it operates for a long time
