Description

Technical Field

[0001] The utility model belongs to the field of testing machines, and in particular relates to an electric push-pull force testing machine. Background Art

[0002] A linear motion mechanism is a mechanical device that outputs energy in the form of linear motion. Generally, a linear motion mechanism can be an electric cylinder, an electro-hydraulic cylinder, a linear motion mechanism, or various linear motion products such as a screw lift.

[0003] The patent application with publication number CN209589512U discloses a push-pull force test bench, including: a bench, a linear motion mechanism to be tested, a tension and compression sensor, a first push-pull rod, a first transmission cylinder, a reversing assembly, at least one second transmission cylinder, a second push-pull rod and at least one counterweight assembly. The output end of the linear motion mechanism is connected to the first push-pull rod through the tension and compression sensor. The tension and compression sensor is used to sense the push-pull force of the linear motion mechanism. One end of the first push-pull rod is connected to the first transmission cylinder, and the first transmission cylinder converts the linear motion of the first push-pull rod into rotational motion. One side of the reversing assembly is connected to the first transmission cylinder, and the other side is connected to the second transmission cylinder. The first transmission cylinder drives the second transmission cylinder to rotate through the reversing assembly, and the second transmission cylinder drives the second push-pull rod to move linearly. The second push-pull rod is connected to the counterweight assembly, and the second push-pull rod drives the counterweight assembly to move.

[0004] However, the above technology has the following disadvantages when used:

[0005] According to the description in the above-mentioned document No. 0033, "the counterweight assembly includes a counterweight block, a counterweight rope and a counterweight support rod. One end of the counterweight rope is connected to the counterweight block, and the other end is connected to the second nut. The lower end of the counterweight support rod is arranged on the stand, and the counterweight rope is placed on the counterweight support rod. The counterweight assembly as a whole can play the role of counterweight. By changing the weight of the counterweight assembly, the working capacity of the linear motion mechanism under different loads can be detected." It can be seen that the weight of the counterweight block needs to be changed to detect the working capacity of the linear motion mechanism under different loads, and the counterweight block needs to be removed from the inside of the counterweight basket. Because the depth inside the counterweight basket is higher than the height of the counterweight block, the efficiency of removing the counterweight block from the inside of the counterweight basket will be reduced.

[0006] Therefore, an electric push-pull force testing machine is proposed to solve the above-mentioned drawbacks. Utility Model Content
