Adjustable balance cylinder

Abstract

The invention discloses an adjustable balance cylinder, which comprises a cylinder body, a front end cover plate, a cylinder shaft seat barrel, a balance cylinder shaft, a flexible assembly baffle, aflexible assemblies, a connector, a bearing connecting rod, a flange adjusting shaft and an adjusting connector, wherein the front end cover plate fixedly covers on the front end of the cylinder body; the cylinder shaft seat barrel is fixed on the front end cover plate; the balance cylinder shaft is located in the cylinder shaft seat barrel and can slide in the cylinder shaft seat barrel; the flexible assembly baffle is connected to one end of the balance cylinder shaft; the flexible assemblies surround the balance cylinder shaft; the connector is connected to the other end of the balance cylinder shaft; the bearing connecting rod is connected with the front end cover plate and the rear end of the cylinder body; the flange adjusting shaft is fixed to the rear end of the cylinder body; the adjusting connector is connected with the flange adjusting shaft and is used for adjusting the pre-compressed amount of the flexible assemblies. According to the adjustable balance cylinder, the pre-compressed amount of the flexible assembly in the cylinder body is adjustable, the work load of a robot is variable, the balanced load acts on the bearing connecting rod, and the service life of the cylinder body is prolonged.

Description

technical field [0001] The invention relates to a balance cylinder, in particular to an adjustable balance cylinder. Background technique [0002] The existing robot two-axis balance cylinder is mainly a spring-type cylinder bearing balance cylinder, and its function is to offset the load torque of the two-axis robot. When the two axes of the robot work within the range of motion, the spring in the balance cylinder is compressed and restored accordingly, and the load torque of the two axes of the robot is balanced by the elastic force provided by the spring. [0003] One of the disadvantages of the balance cylinder in the prior art is that when the two axes of the robot work within the range of motion, all the balanced loads of the balance cylinder fully act on the cylinder body. After working for a long time, the cylinder body is prone to fatigue and damage, and It is inconvenient to replace, thereby increasing the maintenance cost; the second disadvantage of the balance c...

Problems solved by technology

[0003] One of the disadvantages of the balance cylinder in the prior art is that when the two axes of the robot work within the range of motion, all the balanced loads of the balance cylinder fully act on the cylinder body. After working for a long time, the cylinder body is prone to fatigue and damage, and It is inconvenient to replace, thereby increasing the maintenance cost; the second disadvantage of the balance cylinder in the prior art is that the spring compression in the balance cylinder cannot be adjusted, so that the load capacity of the robot cannot be increased without replacing the motor and reducer.
