Description

Technical Field

[0001] The utility model relates to the technical field of piston rods, and particularly relates to a piston rod with anti-deflection guiding. Background Art

[0002] The piston rod is a key component in mechanical equipment and is a connecting component that supports the piston to do work. It is widely used in motion execution components such as oil cylinders and air cylinders. It is a moving component with frequent movement and high technical requirements, and the quality of its processing directly affects the life and reliability of the entire product.

[0003] A Chinese patent with the publication number CN207848086U discloses an air cylinder piston rod, which relates to the technical field of air cylinder mechanical accessories. The key points of its technical solution include a piston rod body. Connecting ends are arranged at both ends of the piston rod body. An inner tube body is arranged at the center of the piston rod body. A honeycomb hole connecting piece is arranged between the inner tube body and the outer wall of the piston rod body. The utility model has the effect that the honeycomb hole connecting piece located inside the piston rod body and outside the inner tube body plays a role in connecting the piston rod body and the inner tube body, and the hexagonal shape structure of the honeycomb hole connecting piece plays a role in significantly improving the structural strength of the air cylinder piston rod, and the through holes in the honeycomb hole connecting piece achieve the purpose of significantly reducing the overall mass of the air cylinder piston rod, thereby reducing the load degree of the air cylinder, and thus prolonging the service life of the air cylinder.

[0004] As described above, this patent provides an air cylinder piston rod, which can reduce the overall mass of the air cylinder piston rod, thereby reducing the load degree of the air cylinder, and thus prolong the service life of the air cylinder. However, during operation, due to continuous piston movement, the piston rod slides continuously. Once the time is too long, the piston rod may deflect, resulting in a deviation in the moving direction of the piston rod, and further making the transmission direction unstable, affecting the stability of the piston rod transmission work. Summary of the Utility Model

[0005] The utility model provides a piston rod with anti-deflection guiding to solve the problems raised in the background art.

[0006] To solve the above problems, the present utility model provides a piston rod with anti-deflection guidance, which includes a cylinder block, a piston clamping rod, a mounting bracket, and an anti-deflection assembly. Rear mounting plates and front mounting plates are respectively fixedly connected to both sides of the cylinder block. The anti-deflection assembly includes a receiving plate. The number of the receiving plates is set to four, and the four receiving plates are all fixedly connected to the surface of the mounting bracket. One end of the piston clamping rod is fixedly connected to the surface of the mounting bracket. A protective sliding rod is slidably connected to the surface of the front mounting plate. A mounting cushion block is fixedly connected to the surface of one end of the protective sliding rod. The protective sliding rod is fixedly connected to the surface of the receiving plate through the mounting cushion block. The end of the protective sliding rod away from the receiving plate penetrates through the front mounting plate and extends between the surfaces of the front mounting plate and the rear mounting plate. A fixed sliding sleeve is fixedly connected to the end of the protective sliding rod between the surfaces of the front mounting plate and the rear mounting plate. The inner side of the fixed sliding sleeve is slidably connected to the surface of the cylinder block.

[0007] Preferably, the number of the protective sliding rods is set to four, and the four protective sliding rods are evenly arranged in a circumferential direction on the surface of the cylinder block. Compression springs are sleeved on the surfaces of the four protective sliding rods between the surfaces of the front mounting plate and the rear mounting plate. Both ends of each compression spring are fixedly connected with a limiting sliding ring. The inner side of the limiting sliding ring is slidably connected to the surface of the protective sliding rod.

[0008] Preferably, a mounting sealing disc is slidably connected to the surface of the piston clamping rod. The surface of the mounting sealing disc is fixedly connected to the surface of the front mounting plate. One end of the piston clamping rod penetrates through the front mounting plate and the cylinder block and extends into the interior of the cylinder block. A working piston is fixedly connected to the end of the piston clamping rod inside the cylinder block.

[0009] Preferably, a rear connecting frame is fixedly connected to the surface of the rear mounting plate. A mounting support rod is fixedly connected to the surface of the rear mounting plate on the side away from the rear connecting frame. The number of the mounting support rods is set to four, and the four mounting support rods are evenly arranged in a circumferential direction on the surface of the rear mounting plate.

[0010] Preferably, one end of the mounting support rod penetrates through the front mounting plate and extends to one side of the front mounting plate. A fixing nut is threadedly connected to the end of the mounting support rod on one side of the front mounting plate.

[0011] The beneficial effects of adopting the above technical solutions are:

[0012] By setting up an anti-deflection component, during operation, the receiving plate is fixed on the installation bracket. The surface of the installation bracket fixes the protective sliding rod through the installation cushion block. One end of the protective sliding rod penetrates through the front installation card plate, and the protective sliding rod can slide on the surface of the front installation card plate. At the same time, a fixed sliding sleeve is fixedly connected to one end of the protective sliding rod to support the protective sliding rod. When performing piston stretching work, the piston clamping rod drives the installation bracket to move, and the movement of the installation bracket drives the receiving plate to move. During the movement process, the protective sliding rod also moves along with the movement of the receiving plate. The design of the protective sliding rod can limit the receiving plate, thereby guiding the piston clamping rod, preventing the piston clamping rod from deflecting, and ensuring the stability of the piston clamping rod transmission work.

[0023] Through the above technical solution, the piston clamping rod 2 can slide inside the cylinder block 1. The mounting bracket 3 is fixed at one end of the piston clamping rod 2. The rear mounting plate 4 and the front mounting plate 5 are respectively fixed on both sides of the cylinder block 1. Four receiving plates 6 are fixed on the surface of the mounting bracket 3, and the four receiving plates 6 are evenly arranged circumferentially on the surface of the mounting bracket 3. During operation, the receiving plates 6 are fixed on the mounting bracket 3. The protective sliding rod 7 is fixed on the surface of the mounting bracket 3 through the mounting cushion block 8. One end of the protective sliding rod 7 penetrates through the front mounting plate 5, and the protective sliding rod 7 can also slide on the surface of the front mounting plate 5. At the same time, a fixed sliding sleeve 9 is fixedly connected to one end of the protective sliding rod 7 for supporting the protective sliding rod 7.

During the movement, the protective sliding rod 7 also moves along with the movement of the receiving plates 6. The design of the protective sliding rod 7 can limit the receiving plates 6, thereby guiding the piston clamping rod 2, preventing the piston clamping rod 2 from deflecting, and ensuring the stability of the transmission work of the piston clamping rod 2.

[0027] Through the above technical solution, the rear connecting frame 14 is fixed on the surface of the rear mounting card board 4, and the rear connecting frame 14 is used to connect an external mounting member.
