[0026] like Figure 1-Figure 4 As shown, a hydraulic locking sleeve performance test platform includes a test bench body 1, a pushing mechanism 4 is fixedly connected to the upper end of the test bench body 1, a detection mechanism 3 is fixedly installed at the lower end of the pushing mechanism 4, and a clamping mechanism 2 is fixedly installed at the upper end of the test bench body 1 and just below the detection mechanism 3. The detection mechanism 3 includes a pushing column 301 and a force claw plate 306. The pushing column 301 is fixedly installed at the lower end of the pushing mechanism 4. A number of first guide columns 302 are evenly fixedly installed on the outer side of the pushing column 301. One end of the first guide column 302 is fixedly installed at the lower end of the pushing mechanism 4. A reciprocating spring 303 is sleeved on the outer side of the first guide column 302. A force claw plate 306 is fixedly installed on the other end of the first guide column 302. One side of the force claw plate 306 is evenly rotated and connected with a number of force claws 304. A return spring 307 is connected between the force claws 304 and the force claw plate 306. A pressure detection head 305 is fixedly installed on the end of the force claw 304 away from the pushing column 301, and a telescopic top column 308 is fixedly connected to the bottom end of the force claw plate 306. The pushing mechanism 4 includes a support frame 402 and a hydraulic rod 404. The support frame 402 is fixedly installed on the test bench body 1. The hydraulic rod 404 is fixedly installed on the upper end of the support frame 402. Second guide columns 401 are fixedly installed on both sides of the hydraulic rod 404. A pressure plate 403 is fixedly installed on the other end of the hydraulic rod 404. The pressure plate 403 is slidably connected to the support frame 402 and the second guide column 401. The pushing column 301 and the first guide column 302 are fixedly installed at the bottom end of the hydraulic rod 404.

[0027] In this way, the hydraulic locking sleeve is placed on the clamping column 201 and fixed by the electromagnetic table 202, and the hydraulic oil is injected into the hydraulic rod 404. The pressure plate 403 will move downward under the injection of hydraulic oil, and when the telescopic top column 308 hits the top of the hydraulic locking sleeve, the force claw 304 will grip the hydraulic locking sleeve, and the multiple pressure detection heads 305 on the force claw 304 will detect the hydraulic locking shaft. The multiple pressure detection heads 305 make the detection more comprehensive, detect product deficiencies, and improve product quality.

[0028] As an optional implementation, Figure 3 As shown, the clamping mechanism 2 includes a cylinder 205 and a sliding block 204. The cylinder 205 is fixedly mounted on the test bench body 1.

The driving cylinder 205 pushes the hydraulic locking sleeve upward to the telescopic top column 308 and then retracts it, so that the pressure of the pressure detection head 305 on the outside of the hydraulic locking sleeve remains consistent. At the same time, the pressure of the pressure detection head 305 on the hydraulic locking sleeve can be adjusted according to the length of the telescopic top column 308, so as to detect the detection values ​​under different pressures, making the detection more comprehensive.

[0030] As an optional implementation, Figure 1 As shown, an electric control panel 5 is fixedly installed on the upper end of the test bench body 1 close to the support frame 402.

[0031] In this way, the pushing mechanism 4, the detection mechanism 3, and the clamping mechanism 2 are electrically connected to the electric control panel 5, and the data is adjusted through the electric control panel 5 to obtain the detection data of the hydraulic locking sleeve under different conditions.

[0032] In this embodiment, the hydraulic locking sleeve is placed on the clamping column 201 and fixed by the electromagnetic table 202, and hydraulic oil is injected into the hydraulic rod 404. The pressure plate 403 will move downward under the injection of hydraulic oil. When the telescopic top column 308 reaches the top of the hydraulic locking sleeve, the force claw 304 will grasp the hydraulic locking sleeve, and the multiple pressure detection heads 305 on the force claw 304 will detect the hydraulic locking shaft. The pressure detection head 305 is rotated by the rotating table 203 to fully detect the outer surface of the hydraulic locking sleeve. The driving cylinder 205 pushes the hydraulic locking sleeve upward out of the telescopic top column 308 and then retracts it, so that the pressure of the pressure detection head 305 on the outside of the hydraulic locking sleeve remains consistent. At the same time, the pressure of the pressure detection head 305 on the hydraulic locking sleeve can be adjusted according to the length of the telescopic top column 308. The pushing mechanism 4, the detection mechanism 3, and the clamping mechanism 2 are electrically connected to the electronic control panel 5. The data is adjusted through the electronic control panel 5 to obtain the detection data of the hydraulic locking sleeve under different conditions, and then the detection values ​​under different pressures are detected to make the detection more comprehensive.
