Problems solved by technology
In the first way, as the length of the spring is extended, the tension of the spring changes linearly and becomes larger and larger, which cannot simulate the actual use situation, but the cost is low; in the second way, the hydraulic or pneumatic cylinder is controlled by a hydraulic pump or air pressure respectively The pump provides pressure, and the applied damping is unstable, which is a fluctuating value. It is necessary to adjust the hydraulic valve to test different damping. The adjustment operation is complicated and the accuracy is not high.

The invention relates to a pull-push force test machine for an electric cylinder. The pull-push force test machine for the electric cylinder comprises a test platform, wherein a fixed seat for installing the fixed end of the electric cylinder, and a movable plate doing reciprocating motion with the stretched end of the electric cylinder are arranged on the test platform; a movable seat is installed on the movable plate; a damping brake for damping the movable plate is further installed on the test platform and comprises an electromagnetic clutch, a speed reducer and a gear-rack mechanism; a rack of the gear-rack mechanism is fixedly connected with the movable plate; a gear is installed at the input end of the speed reducer; the electromagnetic clutch is installed at the output end of the speed reducer. According to the pull-push force test machine for the electric cylinder disclosed by the invention, constant damping is provided during a test with the combination of the electromagnetic clutch and the speed reducer, and the actual use condition is more really simulated, so that the test result is more accurate.
Description
technical field [0001] The invention relates to the technical field of testing devices, in particular to an electric cylinder push-pull force testing machine. Background technique [0002] The electric cylinder is a modular product that integrates the servo motor and the lead screw. It converts the rotary motion of the servo motor into linear motion, and at the same time converts the best advantages of the servo motor - precise speed control, precise revolution control, and precise torque control into -Precise speed control, precise position control, precise thrust control; a new revolutionary product that realizes high-precision linear motion series. It is the best substitute for hydraulic cylinders and air cylinders: Electric cylinders can completely replace hydraulic cylinders and air cylinders, and realize the advantages of a more environmentally friendly, energy-saving, and cleaner environment. It is easy to connect with PLC and other control systems to achieve high-pre...
