At the same time, the two independent clamping mechanisms 4 can be applied to the use scenario where only one end needs to be clamped, thereby improving the applicability of the device.

The telescopic end of 010 is provided with a clamping pad 4011; specifically, the first electric push rod 4010 on the mounting block 409 is telescopically driven to drive the clamping pad 4011 to clamp and limit the hydraulic cylinder, which is convenient for adapting to hydraulic cylinders of different sizes and improving the applicability of the device. The first motor 406 rotates to drive the driving gear 407 so that the meshing driven gear 4013 drives the rotating bracket 408 to rotate, and the guide groove 4012 in the rotating bracket 408 slides and rotates along the support rod 405, and the support rod 405 plays a limiting role on the rotating bracket 408. The rotating bracket 408 can be used to avoid slipping, and the rotation of the rotating bracket 408 drives the mounting block 409 connected thereto to rotate synchronously. The cylinder body can be rotated after clamping, thereby facilitating the processing of the cylinder body and improving the practicability of the device.

[0030] like Figure 2 , Figure 3 , Figure 5 As shown, the auxiliary support mechanism 5 also includes a fixed block 5012, an inclined groove 507 is provided on the mounting frame 504, and the number of the inclined grooves 507 is two groups. A rotating support frame 505 is arranged in the two groups of inclined grooves 507, and a pushing drum 508 is arranged between the two groups of rotating support frames 505. A mounting groove 509 is provided at the other end of the rotating support frame 505, and a plurality of auxiliary rotating wheels 5010 are arranged in the mounting groove 509.

A fixed block 5012 is fixedly provided on the top of one side of the mounting frame 504, and a latch 5013 is movably inserted on the fixed block 5012. A limiting block 5015 is arranged on the surface of the latch 5013, and a spring 501 is sleeved on one side of the limiting block 5015 and the side corresponding to the fixed block 5012. 4; Specifically, by the pushing drum 508 on the rotating support frame 505, the hydraulic cylinder can be driven to roll and translate when the clamping mechanism 4 on one side is pushed, thereby reducing friction resistance and protecting the surface of the hydraulic cylinder; by the auxiliary wheel 5010 on the other side of the rotating support frame 505, the clamping mechanism 4 can be synchronously rotated when rotating on one side; by adjusting the rotation of the rotating support frame 505, the applicability of the device is improved, and the rotating support frame 505 rotated to one side is limited by the inclined groove 507, and the latch 5013 is pulled out into the through hole 5011 to facilitate the rotation conversion of the rotating support frame 505; the limit block 5015 is squeezed by the elastic force provided by the spring 5014, driving the limit block 5015 to be firmly inserted into the through hole 5011, which is convenient for quickly limiting the rotating support frame 505 and improving the safety during use.

[0031] like Figure 5As shown, the size of the through hole 5011 is matched with the size of the latch 5013, and they are movably plugged in. Specifically, by matching the through hole 5011 with the latch 5013, when the plugging is limited, the stability of the auxiliary support mechanism 5 during use is improved.

[0032] In summary: firstly, the distance of the clamping mechanism 4 is adjusted according to the size of the hydraulic cylinder, and the hydraulic cylinder to be processed is placed on the clamping mechanism 4 to clamp and limit the hydraulic cylinder. When the operator needs to process the clamping part of either end of the hydraulic cylinder, the two groups of clamping mechanisms 4 cooperate with each other, and at the same time, the auxiliary support mechanism 5 at the bottom moves to a suitable position and rises to assist in supporting the lifting of the hydraulic cylinder, so that the operator does not need to frequently adjust the clamping position manually, and only needs to adjust the clamping position of the hydraulic cylinder through the cooperation of the clamping mechanism 4 and the auxiliary support mechanism 5, which reduces the intensity of work and the complexity of operation. To improve the processing efficiency, the clamping mechanism 4 at one end of the hydraulic cylinder that needs to be processed is released, and the clamping mechanism 4 on one side is moved away from the processing end. The auxiliary support mechanism 5 is used to support the hydraulic cylinder on one side to avoid sinking due to the gravity of the hydraulic cylinder on one side, so that the hydraulic cylinder on the other side slips when clamping, posing a safety hazard to the operator. At the same time, the shape of the auxiliary support mechanism 5 can be transformed to facilitate the pushing and rotation of the clamping mechanism 4 on the auxiliary support mechanism 5, and to facilitate the clamping mechanism 4 to perform processing operations when clamping on one side. At the same time, two sets of independent clamping mechanisms 4 can be applied to usage scenarios where only one end needs to be clamped, thereby improving the applicability of the device.
