Problems solved by technology

At present, there is no special equipment for testing the push-pull force of linear actuators on the market. Due to the lack of actual push-pull force data, it often causes troubles in valve control. For example: for some high-pressure and large-diameter valves, the required actuator The output push-pu

[0024] Examples:

[0025] Based on the current situation that there is no special test of push-pull force equipment for linear actuators on the market, in the actual application of the valve, the lack of actual push-pull force data will often cause trouble to the valve control. In order to overcome the above Shortcomings, the present invention proposes an actuator push-pull force test device, which has a structure such as figure 1 As shown, it is mainly composed of an actuator 1 provided with a push rod and a brake mechanism that restricts the movement of the push rod. Since the present invention is mainly applied to a linear actuator, in order to test the push and pull force of the push rod, the present invention is A push-pull force sensor 2 is arranged between the push rod and the brake mechanism, and the measured data is combined to realize the precise control of the valve opening and closing position of the actuator. The test principle and operation process are very simple.

Abstract

The invention discloses a push-pull force testing device of an actuator. The push-pull force testing device of the actuator is mainly composed of the actuator (1) provided with a push rod and a braking mechanism limiting the movement of the push rod. A push-pull sensor (2) is arranged between the push rod and the braking mechanism, and the braking mechanism is a control assembly provided with a support structure and comprises a brake (3) and a brake pad (4), wherein the brake (3) is fixed on the support structure, and the brake pad is controlled by the brake (3). The brake pad (4) is arranged along the moving direction of the push rod, and two ends of the push-pull force sensor (2) are respectively connected with the push rod and the brake pad (4). The push-pull force testing device is mainly used for a linear stroke actuator, a detecting scheme is provided to aim at the push rod force, a testing principle is simple, a gap of push-pull testing of the actuator in the prior art is filled, and not only is the control precision of the operating position of a valve improved, but also the push-pull force testing device has the advantages of being simple in structure and easy to operate.

Description

technical field [0001] The invention relates to the field of actuator testing, in particular to a device for testing the push-pull force of the actuator. Background technique [0002] The actuator is a driving device that can provide linear or rotary motion, which uses some kind of driving energy (such as: hydraulic oil, gas, electricity or other energy) and works under the action of a control signal. According to the type of output displacement of the actuator, it can be divided into three types: straight stroke, angular stroke and multi-turn type. Taking the straight stroke actuator as an example, in the existing industrial field, it can act on the control valve and pass through the actuator. Output linear displacement to precisely control the position of the valve. As more and more factories adopt automatic control, manual operation is replaced by machinery or automation equipment, people require the actuator to be able to play an interface role between the control syste...
