Technical Field
[0001] This utility model relates to the field of positioning and detection technology, and in particular to a device for positioning and detecting a sliding shaft with a telescopic pin. Background Technology
[0002] In some mechanical equipment, a shaft is usually installed according to the requirements. By sliding the shaft, functions such as transmission, conveying, positioning, and detection can be realized. However, after the shaft slides, it is usually fixed by clamping. The clamping structure is relatively complex, has poor stability, and cannot detect whether the shaft is in the accurate position after sliding. Utility Model Content
[0003] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a device with a telescopic pin for positioning and detecting a sliding shaft.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A device for positioning and detecting a sliding shaft with a telescopic pin includes a housing, a sliding shaft disposed within the housing and capable of sliding along its axial direction, and a speed-changing gear set rotatably disposed on the sliding shaft. A vertical groove is provided on one side of the outer wall of the sliding shaft, a first positioning groove is provided at one end of the vertical groove, and a second positioning groove is provided at the other end of the vertical groove. The housing also includes a telescopically disposed positioning pin, one end of which can movably extend into the vertical groove, the first positioning groove, or the second positioning groove.
[0006] In some embodiments, an upper cylinder with a lower opening is provided at the upper end of the housing, and an upper medium interface is provided on the upper cylinder. A lower cylinder with a upper opening is provided inside the housing, and a lower medium interface is provided on the lower cylinder. The two ends of the sliding shaft slide up and down inside the upper cylinder and the lower cylinder, respectively.
[0007] In some embodiments, a cylinder is provided at the upper end of the housing, a magnetic piston is provided inside the cylinder, a positioning pin is fixedly connected to the magnetic piston, and both ends of the positioning pin movably pass through the cylinder.
[0008] In some embodiments, a cylinder mounting base is provided at the upper end of the housing, the cylinder is mounted on the cylinder mounting base, and a sensor is provided on the rear side of the cylinder mounting base. The sensor is used to detect the position of the positioning pin, and when the sensor detects the positioning pin, the front end of the positioning pin is located in the vertical groove.
[0009] In some embodiments, the depths of the first positioning groove and the second positioning groove are different.
[0010] In some embodiments, a first magnetic sensor for detecting the position of the magnetic piston is provided on one side of the cylinder, and when the first magnetic sensor detects the magnetic piston, the front end of the positioning pin is located in the first positioning groove.
[0011] In some embodiments, a second magnetic sensor for detecting the position of the magnetic piston is also provided on one side of the cylinder, and when the second magnetic sensor detects the magnetic piston, the front end of the positioning pin is located in the second positioning groove.
[0012] In some embodiments, sealing rings are provided at both the upper and lower ends of the sliding shaft.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. By providing a vertical slide groove on one side of the sliding shaft, and providing a first positioning groove and a second positioning groove at both ends of the vertical slide groove, when the positioning pin is located in the vertical slide groove, it can be used to guide the axial sliding of the sliding shaft, ensuring that the sliding shaft can slide smoothly in the axial direction. When it slides to the position, the positioning pin extends into the first positioning groove or the second positioning groove, thereby limiting and locking the axial sliding and axial rotation of the sliding shaft, realizing the positioning of the sliding shaft. The overall structure is simple and has strong stability.
[0015] 2. Since one end of the positioning pin can be movably inserted into the vertical slide groove, the first positioning groove, or the second positioning groove, the position of the positioning pin can be used to clearly determine whether the sliding shaft is in the accurate position after sliding, thus ensuring normal operation in the future.

[0020] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.
[0021] like Figures 1-4 The device shown includes a sliding shaft positioning and detection device with a telescopic pin, comprising a housing 10, a sliding shaft 1 disposed within the housing 10 and capable of sliding along its axial direction, a vertical groove 3 provided on one side of the outer wall of the sliding shaft 1, a first positioning groove 4 provided at one end of the vertical groove 3, a second positioning groove 5 provided at the other end of the vertical groove 3, and a telescopic positioning pin 6 provided on the housing 10, one end of the positioning pin 6 being movably inserted into the vertical groove 3, the first positioning groove 4, or the second positioning groove 5.
[0022] According to the above structure, a vertical groove 3 is provided on one side of the sliding shaft 1, and a first positioning groove 4 and a second positioning groove 5 are respectively provided at both ends of the vertical groove 3. Thus, when the positioning pin 6 is located in the vertical groove 3, it can be used to guide the axial sliding of the sliding shaft 1, ensuring that the sliding shaft 1 can slide smoothly in the axial direction. When it slides to the position, the positioning pin 6 extends into the first positioning groove 4 or the second positioning groove 5, thereby limiting and locking the axial sliding and axial rotation of the sliding shaft 1, realizing the positioning of the sliding shaft 1. The overall structure is simple and has strong stability.
[0023] Since one end of the positioning pin 6 can extend into the vertical slide groove 3, the first positioning groove 4, or the second positioning groove 5, the position of the positioning pin 6 can be used to clearly determine whether the sliding shaft 1 is in the correct position after sliding, thus ensuring normal operation in the future.
[0024] See Figure 1 , Figure 2 , Figure 4 As shown, a cylinder 31 is provided at the upper end of the housing 10, and a magnetic piston 32 is provided inside the cylinder 31. The positioning pin 6 is fixedly connected to the magnetic piston 32. The two ends of the positioning pin 6 respectively move through the cylinder 31, so that the positioning pin 6 can be extended and retracted by the movement of the magnetic piston 32 inside the cylinder 31.
[0025] Furthermore, a cylinder mounting base 41 is provided at the upper end of the housing 10, and the cylinder 31 is mounted on the cylinder mounting base 41. A sensor 42 is provided on the rear side of the cylinder mounting base 41. The sensor 42 is used to detect the position of the positioning pin 6. When the sensor 42 detects the positioning pin 6, the front end of the positioning pin 6 is located in the vertical slide groove 3. Thus, when the positioning pin 6 retracts backward and the front end of the positioning pin 6 is located in the vertical slide groove 3, the rear end of the positioning pin 6 is detected by the sensor 42, and the detection information is fed back. The operator can then know that the sliding shaft 1 can slide axially.
[0026] Furthermore, a first magnetic sensor 51 for detecting the position of the magnetic piston 32 is provided on one side of the cylinder 31, and when the first magnetic sensor 51 detects the magnetic piston 32, the front end of the positioning pin 6 is located in the first positioning groove 4.
[0027] A second magnetic sensor 61 for detecting the position of the magnetic piston 32 is also provided on one side of the cylinder 31, and when the second magnetic sensor 61 detects the magnetic piston 32, the front end of the positioning pin 6 is located in the second positioning groove 5.
[0028] It should be noted that the depths of the first positioning groove 4 and the second positioning groove 5 are different. Therefore, when the positioning pin 6 is inserted into the first positioning groove 4 or the second positioning groove 5, the depth of insertion is different. Thus, the two positions of the positioning pin 6 can be detected by the first magnetic sensor 51 or the second magnetic sensor 61, so that it can be clearly known whether the positioning pin 6 is in the first positioning groove 4 or the second positioning groove 5, and thus whether the sliding shaft 1 is in the accurate position after sliding.
[0029] See Figure 1 As shown, an upper cylinder 21 with a lower opening is provided at the upper end of the housing 10, and an upper medium interface 23 is provided on the upper cylinder 21. A lower cylinder 22 with a upper opening is provided inside the housing 10, and a lower medium interface is provided on the lower cylinder 22. The two ends of the sliding shaft 1 slide up and down in the upper cylinder 21 and the lower cylinder 22 respectively. Sealing rings 71 are provided at both the upper and lower ends of the sliding shaft 1.
[0030] Gas or liquid is injected through the upper medium interface 23 and the lower medium interface, driving the sliding shaft 1 to slide up and down within the upper cylinder 21 and the lower cylinder 22.
[0031] The device of this application, which has a telescopic pin for positioning and detecting the sliding shaft, can be used in a gearbox. That is, by rotating a gear set 2 on the sliding shaft 1, the gear can switch speeds by following the sliding shaft 1.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
