Description

Technical Field

[0001] The invention relates to the technical field of hydraulic cylinders. Background Art

[0002] With the rapid development of my country's economic construction, the market demand for hydraulic cylinder products is growing. At present, large cranes, excavators, loaders and other highly mechanized equipment are equipped with hydraulic cylinders for lifting, pushing and pulling, and small ones play a core role in the process of lifting and loading. The linear push-pull, corner, thread and other cylinders used on hydraulic tooling fixtures also play a vital role; the lateral push function of the hydraulic cylinder is a problem that currently plagues technicians. Standard hydraulic cylinders cannot withstand lateral forces, let alone achieve lateral push functions. Two cylinders are used in standard designs for functional integration to achieve lateral push functions, which are complex in structure and have poor performance. Summary of the invention

[0003] In order to solve the above-mentioned problems existing in the lateral pushing function of the hydraulic cylinder, the present invention provides a hydraulic cylinder with lateral pushing force.

[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a hydraulic cylinder with lateral driving force, a rear end cover is installed at the rear end of the cylinder body, a joint bearing cover is installed with a clearance fit inside the front end of the cylinder body, a piston rod is arranged in the cylinder body, the piston is slidably installed in the cylinder body, a bottom fixing block with an inclined upper surface is embedded in the lower part of the piston hole, a rotating pin is installed on the inclined surface of the bottom fixing block, the rear end of the piston rod is installed with a clearance fit with the rotating pin, and the front end of the piston rod passes through the joint bearing cover and is installed with a clearance fit through the joint bearing cover.

[0005] The spherical bearing cover is loosely fitted on the cylinder body and is sealed by a sealing ring assembly.

[0006] The hydraulic cylinder piston rod and the spherical bearing cover are clearance-matched and sealed by the cylinder piston rod sealing ring assembly.

[0007] The rotating pin is tooth-shaped connected to the fixed bottom block.

[0008] The beneficial effects of the present invention are as follows: the structural design is simple and reasonable, the volume is small, the weight of the oil cylinder itself is not increased, the structure is compact, and two oil cylinders are not required to achieve the side-pushing effect; in terms of saving personnel utilization and manufacturing costs, since the oil cylinder is pushed sideways, it is easy to accurately position when lifting heavy objects, making adjustment and other work easier and more effective.

[0011] The hydraulic cylinder structure with lateral driving force of the present invention is as follows Figure 1 As shown, it includes a cylinder body 2, a piston rod 6, a joint bearing cover 7, a piston 3, a rear end cover 1, a bottom fixing block 4 and a rotating pin 5. The piston 3 is slidably accommodated in the cylinder body 2, the joint bearing cover 7 is clearance-matched on the cylinder body 2 and is sealed by a sealing ring assembly, the hydraulic cylinder piston rod 6 and the joint bearing cover 7 are clearance-matched and are sealed by the cylinder piston rod sealing ring assembly, the rear end cover 1 is threadedly connected to the cylinder body 2, the lower part of the piston 3 hole is embedded in the bottom fixing block 4 with an inclined upper surface, the rotating pin 5 is installed on the inclined surface of the bottom fixing block 4, the piston rod 6 and the rotating pin 5 are clearance-matched, and the rotating pin 5 is toothedly connected to the fixed bottom block 4.

[0012] When in use, the piston rod 6 pushes the piston 3 to slide in the cylinder body. Due to the action of the inclined bottom fixing block and the rotating pin in the piston 3, lateral pushing is achieved, which makes it easy to accurately position when lifting heavy objects, making adjustment and other tasks easier and more effective.
