[0025] By adopting the above technical solution, when the upper clamping mechanism needs to be replaced or removed for maintenance, first pull the connecting rod 93, squeeze the abutment spring 94, pull out the abutment block 92, so that the connecting tube 91 is separated from the hydraulic rod 10, and then remove the upper clamping assembly for repair or maintenance. When the upper clamping assembly needs to be reassembled, put the connecting column 2 95 back through the hole reserved by the hydraulic rod 10, and rotate to adjust the direction until the abutment block 92 is stuck on the surface of the hydraulic rod 10 under the action of the abutment spring 94, and the installation is completed.

[0026] Specifically, the quick-release assembly 9 further includes a positioning block 96 , wherein the positioning block 96 is disposed on one side of the second connecting column 95 , and a positioning groove is disposed on the inner wall of the hydraulic rod 10 at a position corresponding to the positioning block 96 .

[0028] Specifically, a limiting groove is provided on one side surface of the hydraulic rod 10 corresponding to the position of the abutment block 92 .

[0029] By adopting the above technical solution, it is ensured that the abutment block 92 can be stably clamped on the hydraulic rod 10, thereby ensuring the connection quality.

[0030] When this embodiment is in use: when the upper clamping mechanism needs to be replaced or removed for maintenance, first pull the connecting rod 93, squeeze the abutment spring 94, pull out the abutment block 92, so that the connecting tube 91 is separated from the hydraulic rod 10, and then remove the upper clamping assembly for repair or maintenance. When the upper clamping assembly needs to be reassembled, the positioning block 96 on the surface of the connecting column 95 is installed along the positioning groove on the inner wall of the hydraulic rod 10, so that the abutment block 92 is accurately stuck in the limiting groove on the surface of the hydraulic rod 10 under the action of the abutment spring 94, completing the resetting installation of the upper clamping mechanism.

[0031] Example 2

[0032] The present embodiment is different from the embodiment 1 in that: specifically, the rotating assembly 1 includes a protective box 11, a rotating pulley 12, a connecting column 13, a pull rod 14, a spring 15, a limit block 16 and a gear 17, wherein a connecting column 13 is provided at the upper end of the hydraulic rod 10, a gear 17 is provided at the upper end of the connecting column 13, a rotating pulley 12 is provided at the bottom end of one side of the gear 17, a protective box 11 is provided at the upper end of the gear 17, a pull rod 14 is provided at one side of the protective box 11, a limit block 16 is provided at one side of the pull rod 14, and a spring 15 is provided on the surface of one side of the pull rod 14.

[0033] By adopting the above technical solution, when the device needs to clamp an irregular object, the angle of the upper clamping mechanism needs to be changed. By pulling the pull rod 14 and compressing the spring 15, the limit block 16 and the gear 17 are separated. At this time, the hydraulic rod 10 is driven to rotate through the cross plate 8, and the hydraulic rod 10 drives the connecting column 13 to rotate. The connecting column 13 drives the gear 17 to rotate, and the rotating pulley 12 connected to the gear 17 rotates at the upper end of the beam 2. When it rotates to a suitable angle, the pull rod 14 is released to reset the limit block 16 and the spring 15, limiting the rotation of the gear 17, thereby ensuring the stability of the position of the upper clamping mechanism during the clamping process of the device and ensuring production safety.

[0034] Specifically, the limit block 16 is meshedly connected with the gear 17 , the rotating pulley 12 is fixedly connected with the gear 17 , and the rotating pulley 12 can rotate on the upper end surface of the beam 2 .

[0035] By adopting the above technical solution, the rotation of the upper clamping mechanism is made more portable.

[0036] When this embodiment is in use: when the device needs to clamp an irregular object, the angle of the upper clamping mechanism needs to be changed, and the limit block 16 and the gear 17 are separated by pulling the pull rod 14 and compressing the spring 15. At this time, the hydraulic rod 10 is driven to rotate through the cross plate 8, and the hydraulic rod 10 drives the connecting column 13 to rotate, and the connecting column 13 drives the gear 17 to rotate. The rotating pulley 12 connected to the gear 17 rotates at the upper end of the beam 2. When it rotates to a suitable angle, the pull rod 14 is released to reset the limit block 16 and the spring 15, limiting the rotation of the gear 17, thereby ensuring the stability of the position of the upper clamping mechanism during the clamping process of the device and ensuring production safety.

[0037] The structure and use principle of the cross beam 2, support column 3, base plate 4, lower clamping power box 5, lower clamping block 6, upper clamping block 7, cross plate 8 and hydraulic rod 10 in the utility model have been disclosed in a drive shaft clamping tool disclosed in Chinese patent application No. 202221745333.3.

[0038] Working principle and use process of the utility model: when the upper clamping mechanism of the device is repaired or maintained, the connecting rod 93 is pulled to squeeze the abutting spring 94, and the abutting block 92 is pulled out, so that the connecting tube 91 is separated from the hydraulic rod 10, and then the upper clamping assembly is removed for repair or maintenance. When the upper clamping assembly needs to be reassembled, the positioning block 96 on the surface of the connecting column 95 is installed along the positioning groove of the inner wall of the hydraulic rod 10, so that the abutting block 92 is accurately stuck in the limiting groove on the surface of the hydraulic rod 10 under the action of the abutting spring 94, and the resetting installation of the upper clamping mechanism is completed, making the disassembly and assembly of the upper clamping mechanism more portable, shortening the time required for replacing the upper clamping mechanism, and improving work efficiency;

[0039] When the device needs to clamp an irregular object, the angle of the upper clamping mechanism needs to be changed. By pulling the pull rod 14 and compressing the spring 15, the limit block 16 and the gear 17 are separated. At this time, the hydraulic rod 10 is driven to rotate through the cross plate 8, and the hydraulic rod 10 drives the connecting column 13 to rotate. The connecting column 13 drives the gear 17 to rotate, and the rotating pulley 12 connected to the gear 17 rotates at the upper end of the beam 2. When it rotates to a suitable angle, the pull rod 14 is released to reset the limit block 16 and the spring 15, limiting the rotation of the gear 17, thereby ensuring the stability of the position of the upper clamping mechanism during the clamping process of the device and ensuring production safety.
