Technical Field

[0001] This utility model relates to the field of hydraulic cylinder assembly technology, specifically to an assembly fixture for a hydraulic cylinder. Background Technology

[0002] Hydraulic cylinders are a very important component of hydraulic machinery, playing the role of an actuator in the entire hydraulic machinery. A hydraulic cylinder is basically composed of a cylinder body, cylinder head, piston, and piston rod.

[0003] The piston is installed on the outside of the piston rod and then installed in the hydraulic cylinder body. Specifically, before leaving the factory, the hydraulic cylinder body and the piston rod with the piston need to be assembled. When assembling the hydraulic cylinder, it is necessary to ensure that the cylinder barrel and the piston rod are on the same axis. The existing hydraulic cylinder assembly is generally done by the operator manually using force to push the piston rod into the hydraulic cylinder body, which is greatly affected by the operator's strength and skill.

[0027] Combined with appendix Figures 1-3 An assembly fixture for a hydraulic cylinder includes a connecting block 1. A clamp 2 for fixing the hydraulic cylinder body is installed on the outer side of the connecting block 1. The clamp 2 includes a guide rod 201 that is movably connected to the connecting block 1. Movable blocks 202 are installed on the outer side of the guide rod 201. A connecting rod 203 is installed at the lower end of the movable block 202. Clamping plates 204 for fixing the hydraulic cylinder body are installed at the lower ends of the two connecting rods 203. A through hole 5 for cooperating with the guide rod 201 is opened on the movable block 202. A waist hole 6 for cooperating with the guide rod 201 is opened on the connecting block 1. The two clamping plates 204 are fixedly connected by bolts and nuts. Specifically, the two clamping plates 204 are connected by bolts and nuts, clamping the hydraulic cylinder body in the middle to achieve a fixed connection of the hydraulic cylinder body, which facilitates the subsequent installation of a piston rod with a piston.

[0028] In specific implementation of this utility model, such as Figure 1 and Figure 2 As shown, a pushing device 3 is installed on the connecting block 1 to push the piston rod into the hydraulic cylinder body. The pushing device 3 includes a threaded rod 301 threadedly connected to the connecting block 1, and a stop block 302 is installed at the lower end of the threaded rod 301. A threaded hole is opened on the connecting block 1 to cooperate with the threaded rod 301. The threaded rod 301 rotates and moves in the threaded hole, thereby driving the stop block 302 to approach the piston rod and pushing the piston rod into the hydraulic cylinder body.

[0029] In specific implementation of this utility model, such as Figures 1-3As shown, a clamping device 4 for clamping the piston rod is installed on the outside of the pushing device 3. The clamping device 4 includes a nut 401 threadedly connected to the outside of the threaded rod 301. A limit block 402 is installed on the upper end of the nut 401. Multiple sets of movable arms 403 are hinged to the outside of the block 302. A stop block 404 is installed on the upper end of the movable arm 403. The opposing surfaces of the stop block 404 and the limit block 402 are inclined and adapted to each other. A moving hole 7 is opened on the limit block 402 to cooperate with the movement of the threaded rod 301. The nut 401 is on the threaded rod 301. The outer side of 01 rotates, causing the limiting block 402 to move. The limiting block 402 moves outside the threaded rod 301 through the moving hole 7. The opposing surfaces of the stop block 404 and the limiting block 402 are inclined and adapted. The movement of the limiting block 402 will cause the stop block 404 to move outward. The movable arm 403 is hinged to the stop block 302, so that the movable arm 403 can move. The lower end of the movable arm 403 clamps the piston rod. Then, through the pushing device 3, the piston rod is rotated downward and enters the hydraulic cylinder body, which can achieve rapid assembly.

[0030] The working principle of this utility model:

[0031] like Figure 2 As shown, the two clamping plates 204 are connected by bolts and nuts, and the hydraulic cylinder body is clamped in the middle to achieve a fixed connection of the hydraulic cylinder body. The threaded rod 301 rotates and moves in the threaded hole, thereby driving the stop block 302 to approach the piston rod and pushing the piston rod into the hydraulic cylinder body.

[0032] The nut 401 can also be rotated on the outside of the threaded rod 301 to drive the limit block 402 to move. The limit block 402 moves on the outside of the threaded rod 301 through the moving hole 7. The opposing surfaces of the stop block 404 and the limit block 402 are both inclined and adapted. When the limit block 402 moves, it will drive the stop block 404 to move outward. The movable arm 403 is hinged to the stop block 302, so that the movable arm 403 can move. The lower end of the movable arm 403 clamps the piston rod. Then, through the pushing device 3, the piston rod is driven to rotate downward and enter the hydraulic cylinder body, which can achieve rapid assembly.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
