Description

Technical Field

[0001] The present invention relates to the technical field of control boxes, and particularly to a multifunctional proximity switch installation control box. Background Art

[0002] In modern industrial production, proximity switches are widely used in fields such as position detection and speed monitoring, and are one of the key components for realizing automatic control. However, the following problems exist:

[0003] The traditional installation method of proximity switches has poor flexibility. When multiple different function limiters need to be installed at the same position, the installation is cumbersome, the debugging is troublesome, and the accuracy is poor.

[0004] For mechanical motion devices, gear systems, lead screw systems, etc., due to long-term operation, the mechanical moving parts wear, resulting in an increase in the gap, causing the detection distance of the proximity switch to change, signal loss and damage.

[0005] When the mechanical motion device operates under heavy load, due to its inertia and shaking, the proximity switch signal is lost or the switch is damaged.

[0006] Due to the above problems, the traditional installation method of proximity switches cannot meet the diverse control requirements and limits its effective application in complex industrial environments.

[0007] Therefore, it is necessary to design a new technical solution to solve this problem. Summary of the Invention

First strip-shaped holes and second strip-shaped holes are respectively opened on both side walls of the box body. A first proximity switch and a second proximity switch are respectively fixedly installed through both sides of the inner cavity of the first strip-shaped hole, and a third proximity switch is fixedly installed through the inner cavity of the second strip-shaped hole;

[0010] Through holes are opened on the other two side walls of the box body, and a guide rod assembly penetrates through the two through holes;

[0011] One end of the guide rod assembly is connected with an adjustment assembly, and the adjustment assembly is used for adjustment and compensation after wear;

[0012] It also includes;

[0013] A limit assembly, which is arranged on one side of the box body and is used for limiting the guide rod assembly.

[0014] By adopting the above technical solution, first install the box body on the external device at the position to be adjusted, then install the limiting component at the position stop position, and then drive the box body to move along with it during the movement of the device. When the device moves to a stop, the guide rod component will move in the opposite direction relative to the box body. At this time, the first proximity switch will be triggered, so the first proximity switch. At this time, when it reaches the stop, the first proximity switch will feedback the signal to the industrial control computer, so the industrial control computer will control the external device to stop moving. When the first proximity switch fails, at this time, the guide rod component will continue to move, so the third proximity switch and the second proximity switch will be triggered, and the signal will be fed back to the industrial control computer. The servo system of the industrial control computer will urgently stop the movement of the device, which is beneficial to avoid danger. And when the device moves back and resets, the guide rod component can automatically reset after disengaging from the limiting component, which is convenient for reuse.

[0060] It should be understood that during use, first install the box body 1 on the external device at the position that needs to be adjusted, then install the limiting component at the position stop position. Then, during the movement of the device, the box body 1 will be driven to move accordingly. When the device moves to the stop position, the guide rod component will move in the opposite direction relative to the box body 1. At this time, the first proximity switch 16 will be triggered, and thus the first proximity switch 16. At this time, when reaching the stop position, the first proximity switch 16 will feedback the signal to the industrial control computer, so that the industrial control computer will control the external device to stop moving.
