Description

Technical Field

[0001] The utility model belongs to the technical field of electric cylinder testing, in particular to a thrust detection workbench for electric cylinder testing. Background Art

[0002] Electric cylinders are more environmentally friendly, more energy-efficient and cleaner, and can be easily connected to control systems. They can even replace hydraulic cylinders and pneumatic cylinders to achieve high-precision motion control. After production or maintenance, the thrust and extension length of the electric cylinder need to be tested to determine whether the electric cylinder is qualified.

[0003] The Chinese patent application number CN202321593325.6 discloses an electric cylinder test platform, including an electric cylinder main unit and a platform, the electric cylinder main unit is arranged at the upper end of the platform, and a length pressure test mechanism is arranged on the surface of the platform, and the length pressure test mechanism includes a cylinder groove, a slide bar, a limit block, a lifting platform, a slide hole, a spring sleeve, a spring, a push block, a push rod, a pressure sensor, a groove and a scale, and a mobile power supply mechanism is arranged on one side of the electric cylinder main unit; the utility model can be tested by the length pressure test mechanism when the electric cylinder needs to be tested, and the data is very accurate, the cost is low, and the problem of needing to purchase professional testing tools and being expensive is avoided. However, when the above device is actually used, it is only to place the electric cylinder into the cylinder groove, and fix the two ends of the electric cylinder through the cylinder groove groove. When the electric cylinder is extended and retracted, it is easy to be unstable, which affects the test accuracy. There are also many types of electric cylinders. The cylinder groove groove cannot be used for electric cylinders of different sizes, and the scale is fixedly installed. When judging the extension length of the electric cylinder, it is necessary to determine the distance between the starting point and the end point, which is more troublesome to use.

[0004] In view of this, the present utility model is proposed. Utility Model Content
