Description

Technical Field

[0001] The invention relates to the technical field of travel switch testing, and more specifically to a simulation testing device for a travel switch. Background Art

[0002] The travel switch, also known as the limit switch, is a commonly used low-current main control electrical appliance. The collision of the moving parts of the production machinery is used to make its contacts move to connect or disconnect the control circuit to achieve a certain control purpose. Usually, this type of switch is used to limit the position or stroke of mechanical movement, so that the moving machinery can automatically stop, reverse, change speed or automatically reciprocate at a certain position or stroke. After the travel switch is produced, the performance of the travel switch needs to be tested to detect the service life and rebound performance of the travel switch.

[0003] The existing travel switch test equipment has some shortcomings during use, as follows:

[0004] When the existing simulation test equipment for the travel switch is used, after the travel switch is positioned, a reciprocating impactor is used to impact the rotating arm of the travel switch, and at the same time, whether the travel switch can be used normally is detected until the travel switch cannot work normally. At this time, the number of swings of the impactor arm can be counted to infer the service life of the travel switch.

[0014] Technical effects and advantages of the present invention:

[0015] 1. In the process of the travel switch simulation test, the present invention firstly drives the first hydraulic telescopic rod to extend through the operation of the first hydraulic rod, and then pushes the U-shaped clamping block to descend inside the clamping lifting groove, and then increases the distance between the bottom of the inner side of the U-shaped clamping block and the first hydraulic rod, and then places the travel switch to be tested between the U-shaped clamping block and the first hydraulic rod, and then drives the first hydraulic telescopic rod to contract through the operation of the first hydraulic rod, so that the travel switch to be tested can be positioned, and then drives the second gear assembly to rotate through the operation of the second servo motor, and then drives the second gear assembly to rotate, and then drives the second gear assembly to rotate, through the teeth on the outer side of the second gear assembly and the first servo motor. The mutual meshing between the outer teeth of the gear assembly drives the first gear assembly to rotate, and then drives the first impact assembly and the second impact assembly to rotate. The first impact assembly can be used to impact the travel switch from left to right, and the second impact assembly can be used to impact the travel switch from right to left. When the second servo motor completes one circle of rotation, the impact arm of the travel switch can swing left and right twice on one side, and at the same time, it monitors whether the travel switch can work normally. The test work is stopped after the travel switch fails. At this time, the service life of the travel switch can be calculated by the number of rotations of the second servo motor, which is convenient for quickly completing the simulation detection of the travel switch.

[0016] 2. When the hardness test of the travel switch housing is required, the second hydraulic cylinder is used to drive the second hydraulic telescopic rod to extend, and then the hexagonal lifting block is driven to descend, and then the connecting block and the hexagonal lifting ring are driven to descend, and then the second U-rotation positioning block, the transmission rod and the first U-rotation positioning block are driven to rotate along the positioning rod at an angle until it is perpendicular to the outer side of the hexagonal positioning block, and then the first servo motor is used to drive the hexagonal positioning block to rotate, and then the hexagonal positioning block and the rotation push assembly are driven to rotate, and then the second servo motor is used to drive the second gear assembly to rotate, and then the second impact assembly is brought close to the travel switch, so as to test the wear resistance of the formed switch, and the wear resistance test of the travel switch can be completed at the same time.

[0017] 3. The present invention rotates the second positioning threaded pin to separate the second positioning threaded pin from the second limiting cylinder, thereby reducing the friction between the second positioning threaded pin, the first servo motor and the first gear assembly, so that the second impact assembly can slide on the guide rod, thereby adjusting the position of the second impact assembly. The same operation can also adjust the position of the first impact assembly, so that the device can detect travel switches of different sizes, thereby expanding the detection range of the device.
