[0034] During the specific implementation of this embodiment, the device can detect multiple speed sensors 4 at the same time during use, thereby improving the detection efficiency, making it easier to replace the speed sensor 4, and providing a wider detection range, thereby making the detection result more accurate and having extremely high application value.

[0035] In one example of the present invention, the speed sensor 4 in the present application is electrically connected to an external controller so that the detected data can be transmitted to the controller in a timely manner during the detection process. When the rotating mechanism 300 is rotating, the speed sensor 4 detects it. The speed sensor 4 that detects different data is considered abnormal and is picked out.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, the clamping mechanism 100 includes a fixing plate 5 fixedly mounted on the bottom plate of the frame 1, a hydraulic cylinder 7 mounted on the fixing plate 5, a mounting seat 8 arranged at the movable end of the hydraulic cylinder 7, a movable rod 9 hinged on the mounting seat 8, and a clamping plate 11 mounted on the free end of the movable rod 9;

[0037] Support rods 6 are symmetrically arranged on both sides of the fixed plate 5 , and a sleeve 10 is hinged at the free end of the support rod 6 , and the sleeve 10 is slidably connected to the movable rod 9 .

[0038] During the specific implementation of this embodiment, the number of movable rods 9 set in this application is adjusted according to the speed sensors 4 placed on the support ring 2, so as to fix multiple speed sensors 4 at the same time, and the hydraulic cylinder 7 works to push the mounting seat 8 to move in the height direction, and the mounting seat 8 drives the movable rod 9 to swing in the plane along the sleeve 10, and drives the clamping plate 11 to move synchronously, and when the mounting seat 8 moves upward, the clamping plate 11 realizes the clamping work of the speed sensor 4, and when the mounting seat 8 moves downward, the clamping plate 11 pushes the speed sensor 4 upward, so that the speed sensor 4 breaks away from the positioning column 3 and falls downward.

[0039] like Figure 1 and Figure 4 As shown, as another preferred embodiment of the present invention, the guide mechanism 200 includes a second positioning column 13 slidably mounted on the frame 1, a support plate 12 mounted on the top of the second positioning column 13, a second sleeve 15 slidably mounted on the second positioning column 13, and a telescopic member 17 mounted on the support plate 12 and hinged to the second sleeve 15;

[0040] The frame 1 is provided with a limiting groove 14 for the second positioning column 13 to slide, and a card slot 16 for the second sleeve 15 to be inserted;

[0041] A cross bar 18 is fixedly connected to the inner side of the second sleeve 15 , and a fixing frame 19 is installed at one end of the cross bar 18 .

[0042] During the specific implementation of this embodiment, the telescopic member 17 described in this application can select linear drive devices such as air cylinders, hydraulic cylinders, electric cylinders, and electric telescopic rods, and adjust them according to actual needs. They are not listed one by one here. When used, the guide mechanism 200 is limited by the set limiting mechanism 400, and the telescopic member 17 works to push the sleeve 2 15 to slide in the height direction along the surface of the positioning column 2 13. The cross bar 18, the fixed frame 19, and the rotating mechanism 300 move synchronously with the sleeve 2 15. When the cross bar 18 slides downward to the extreme position, it is inserted into the slot 16.

[0043] like Figure 1 and Figure 4 As shown, as another preferred embodiment of the present invention, the rotating mechanism 300 includes a driving motor 20 disposed at the execution end of the guide mechanism 200, a transmission shaft 21 connected to the output end of the driving motor 20, and a swing rod 23 fixedly mounted at the bottom of the transmission shaft 21;

Examples are not given one by one here. After the height position of the rocker arm 23 is adjusted by the set guide mechanism 200, the drive motor 20 drives the transmission shaft 21 to rotate along the bushing 22, and the rocker arm 23 and the magnetic pole 24 rotate synchronously with the transmission shaft 21. When the magnetic pole 24 rotates, the speed sensor 4 detects its rotation speed.

[0046] like Figure 1 , Figure 5 and Figure 6 As shown, as another preferred embodiment of the present invention, the limiting mechanism 400 includes an L-shaped plate 25 slidably mounted on the frame 1, a through hole 1 27 arranged on the side of the L-shaped plate 25, a through hole 28 provided on the frame 1 and cooperating with the through hole 1 27, and an insertion rod 29 slidably connected with the through hole 1 27 and the through hole 28;

[0047] The frame 1 is provided with a second limiting groove 26 for the L-shaped plate 25 to slide in the height direction.

[0048] During the specific implementation of this embodiment, the L-shaped plate 25 described in this application is fixedly connected to the bottom end of the support plate 12. After the position of the speed sensor 4 is contacted by the set clamping mechanism 100, the insertion rod 29 is pulled out from the through hole 1 27 and the through hole 2 28, and the position of the L-shaped plate 25 on the limiting groove 26 is adjusted to facilitate the limiting work of the speed sensor 4, and move up after the detection is completed to release the lock of the speed sensor 4, so as to facilitate the automatic unloading of the speed sensor 4 under the push of the clamping mechanism 100.

[0049] like Figure 1 As shown, as another preferred embodiment of the present invention, it also includes a base 30 fixedly mounted on the frame 1, and a slideway 32 arranged on the frame 1 at the end of the base 30;

[0050] A protective pad 31 is bonded to the surface of the base 30 , and the protective pad 31 is made of rubber material.

[0051] During the specific implementation of this embodiment, the speed sensor 4 after detection falls downward under the push of the clamping mechanism 100, and the descending speed sensor 4 falls on the base 30, slides along the inclined surface of the base 30, and slides out of the slide 32. By setting the protective pad 31, the speed sensor 4 can be prevented from being damaged in contact with the base 30.

[0052] To sum up, when in use, the speed sensor 4 is placed on the positioning column 3, the hydraulic cylinder 7 works to push the mounting seat 8 to move in the height direction, the mounting seat 8 drives the movable rod 9 to swing along the sleeve 10 in the plane, and drives the clamping plate 11 to move synchronously, and when the mounting seat 8 moves upward, the clamping plate 11 realizes the clamping work on the speed sensor 4, the bottom surface of the L-shaped plate 25 contacts the speed sensor 4, the insertion rod 29 is inserted into the through hole 1 27 and the through hole 2 28, the telescopic member 17 works to push the sleeve 2 15 to slide in the height direction along the surface of the positioning column 2 13, the cross bar 18 and the fixed frame 19 move synchronously with the sleeve 2 15, the drive motor 20 works to drive the transmission shaft 21 to rotate along the bushing 22, the rocker 23 and the magnetic pole 24 rotate synchronously with the transmission shaft 21, and the magnetic pole 24 rotates Under the condition that the speed sensor 4 detects its rotation speed and transmits the detection result to the external controller, and selects the speed sensor 4 with good or bad quality. After the detection, the L-shaped plate 25 is separated from the speed sensor 4. When the mounting seat 8 moves downward, the pressing plate 11 pushes the speed sensor 4 upward to lift it up and separate it from the positioning column 3. The speed sensor 4 will fall downward without a fulcrum and fall on the surface of the base 30 and slide out of the slide 32. According to the recorded results, the speed sensor 4 with good quality is selected. During the use of this equipment, multiple speed sensors 4 can be detected at the same time, the detection efficiency is improved, the speed sensor 4 is more convenient to replace, and the detection range is wider, so that the detection result is more accurate and has extremely high application value.
