Detailed Description
The technical solution of the present invention is clearly and completely described below with reference to the drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
The retractable proximity switch detection device shown in fig. 1 and 2 comprises a proximity switch body 1, a sensing piece 2, a retractable assembly 3, a mounting plate 4 and a locking nut 5, wherein the retractable assembly 3 penetrates through the mounting plate 4 and is fastened on a part to be detected through the locking nut 5, the retractable assembly 3 is used for positioning the sensing piece 2 and comprises a retractable rod 301, a guide rod 302, a guide sleeve 303, a spring 304 and a fixing sleeve 305, the guide rod 302 penetrates through the fixing sleeve 305 and is in threaded connection with the fixing sleeve 305, the retractable rod 301, the guide sleeve 303 and the spring 304 are symmetrically arranged at two ends of the fixing sleeve 305, the spring 304 is sleeved on the guide rod 302, two ends of the spring 304 are respectively abutted against the guide rod 302 and the retractable rod 301, the guide sleeve 303 covers the spring 304, one end of the spring is in threaded connection with the fixing sleeve 305, the other end of the retractable rod 301 is limited, the sensing piece 2 is arranged at the other end of the retractable rod 301, and external threads matched with the locking nut 5 are arranged on the guide sleeve 303.
In this embodiment, proximity switch body 1 and response piece 2 are equipped with two sets ofly, and the both ends of flexible subassembly 3 are located respectively to two sets of response pieces 2, and two sets of proximity switch bodies 1 are just setting up to a set of response piece 2 respectively.
In this embodiment, the telescopic rod 301, the guide rod 302, the guide sleeve 303 and the fixing sleeve 305 are coaxially disposed.
In this embodiment, the sensing piece 2 is screwed to the other end of the telescopic rod 301.

In the practical application process, the mounting plate 4 is connected to the detected moving part, the proximity switch body 1 judges the state of the moving part through the position of the sensing piece 2 on the sensing detection device, when the sensing piece 2 reaches the sensing area of the proximity switch body 1 along with the moving part, the related control system can send a stop instruction to the moving part, the movement of the moving part can lag behind the control instruction and continue to move towards the direction of the proximity switch body 1, so that the sensing piece 2 is in contact with the proximity switch body 1, at the moment, the sensing piece 2 pushes the telescopic rod 301 in the telescopic assembly 3 to compress the spring 304 under the action of external force and moves towards the opposite direction of the proximity switch body 1 along the guide rod 302, the spring 304 deforms under the action of external force to absorb shock and impact energy, so that the buffering effect is achieved, the damage of the proximity switch body 1 due to collision is prevented, and meanwhile, the collision deformation of the sensing piece 2 is avoided, and the reliability of signals is influenced; at this moment, if the moving part is far away from the proximity switch body 1 under the action of external force, the spring 304 in the telescopic assembly 3 is restored to the original state, so that the sensing piece 2 is always in the sensing area of the proximity switch body 1, and the signal loss is avoided.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
