Robot joint decelerator transmission performance testing device with mobile slide unit

Abstract

The invention discloses a robot joint decelerator transmission performance testing device with a mobile slide unit. The robot joint decelerator transmission performance testing device includes the mobile slide unit, the mobile slide unit includes a first slide device and a second slide device, the first slide device is provided with a first slide platform and a gear, the gear is fixed on a frame through a center shaft, the first slide platform is provided with a tooth bar, the tooth bar is engaged with the gear, the second slide device is provided with a second slide platform, the second slide platform is provided with a screw rod nut pair, the screw rod nut pair includes a screw rod and a nut, the nut is fixed on the second slide platform, and the screw rod is fixed on the frame. The tooth bar and the gear are arranged on the first slide platform, the rotation of the gear is converted into the linear movement of the tooth bar, the rotation of the screw rod is converted into the linear movement of the nut, the distance between the linear movement of the first slide platform fixed with the tooth bar and the linear movement of the second slide platform fixed with the nut can be conveniently controlled, and the problems of manual pushing and low movement precision of a slide unit in the prior art can be solved.

Description

technical field [0001] The present disclosure generally relates to the field of test devices, in particular to the field of test devices for transmission performance of reducers, and in particular to a test device for transmission performance of a robot joint reducer with a moving slide. Background technique [0002] There are two main types of joint reducers currently used in the field of robotics: one is the RV reducer and the other is the harmonic reducer. In the articulated robot, the RV reducer belongs to the cycloid precision reducer, which has high rigidity and rotation accuracy. In the design of the robot, the RV reducer is generally placed at the heavy load position of the boom and the frame, and the harmonic deceleration The reducer is placed on the waist and hand of the forearm. The motion accuracy and performance of the reducer at all robot joints directly affect the overall working performance and service life of the industrial robot. [0003] With the rapid de...

Problems solved by technology

[0007] According to the technical solution provided by the embodiment of the present application, by setting the gear rack on the first sliding platform to mesh with the gear, the rotation of the gear is converted into the linear motion of the rack, and the rotation of the lead screw is converted into the linear motion of the nut, which is convenient for controlling the fixed gear. The linear motion distance between the first sliding platform of the rack and the second sliding platform fixed with nuts can solve the problem of low motion accuracy of the existing sliding platform relying on manual push
