[0004] However, the pushing rod and rotating rod in the punching gun cavity in the above-mentioned patent will generate friction with the shell, resulting in heating of the shell. Utility model content

[0005] In view of the deficiencies of the prior art, the utility model provides a roller needle type multi-bearing punch gun cavity structure, which solves the problem that the pushing rod and rotating rod in the punch gun cavity will generate friction with the shell, resulting in heating of the shell.

[0006] To achieve the above purpose, the utility model realizes the following technical scheme: a roller needle type multi-bearing punch gun cavity structure, comprising a shell, a connecting sleeve is threadedly connected to one end of the shell, a moving sleeve is arranged in the inner cavity of the shell, and a rotating rod is threadedly connected to the inner cavity of the moving sleeve, a limiting ring is arranged on the surface of the rotating rod, a bearing assembly is arranged on the surface of the moving sleeve, and a plurality of roller needles are symmetrically arranged on the surface of the moving sleeve, and a pushing rod is arranged at one end of the moving sleeve.

[0007] Preferably, the bearing assembly includes a deep groove bearing, a flat bearing, and a snap fastener, and a gasket is provided between the deep groove bearing, the flat bearing, and the snap fastener.

[0008] Preferably, the deep groove bearing, the flat bearing, the snap fastener, and the gasket are movably sleeved on the surface of the rotating rod, and the deep groove bearing abuts against the limiting ring. The deep groove bearing, the flat bearing, the snap fastener, and the gasket are located in the inner cavity of one end of the outer shell.

[0009] Preferably, the push rod is provided with a push head and a threaded connector at both ends, and the threaded connector is threaded onto one end of the movable sleeve.

[0012] This invention provides a cavity structure for a needle roller type multi-bearing punch. Compared with the prior art, it has the following advantages:

[0013] The cavity structure of this needle roller multi-bearing punch uses deep groove bearings and clips to reduce the friction between the rotating rod and the housing during rotation, which can reduce the housing temperature. Then, the thread drives the moving sleeve to extend and retract through the needle rollers in the inner cavity of the housing. The three-sided needle roller design greatly reduces the friction between the push rod and the housing, reducing the temperature rise. While the bearing assembly and moving sleeve reduce the temperature rise, they also prevent the oil in the inner cavity of the housing from heating up. Reducing the temperature rise can also reduce the oil consumption problem in the cavity. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a cylinder structure for a needle roller multi-bearing punch, including a housing 1, one end of which is threaded with a connecting sleeve 11, and the other end of which is threaded with a connector 2. An external electric gun can be connected through the connector 2, which can refer to the electric gun in CN114393121A. An oil inlet is provided on the surface of the housing 1. Before use, oil is injected into the inner cavity of the housing 1 and then sealed with screws. The oiling provides a lubrication effect.

[0021] The inner cavity of the outer shell 1 is provided with a movable sleeve 6, and a rotating rod 4 is threadedly connected to the inner cavity of the movable sleeve 6. A limit ring 41 is provided on the surface of the rotating rod 4. A bearing assembly 5 is provided on the surface of the movable sleeve 6, and needle rollers 61 are symmetrically rolled on the surface of the movable sleeve 6. A push rod 3 is provided at one end of the movable sleeve 6. The two ends of the movable sleeve 6 are different sizes, and the larger surface is provided with needle rollers 61. The needle rollers 61 will contact the inner wall of the outer shell 1 to achieve rolling sliding, reduce friction, and prevent the push rod 3 from directly contacting the inner wall of the outer shell 1.

[0022] The bearing assembly 5 includes a deep groove bearing 51, a flat bearing 52, and a snap fastener 53. A gasket 54 is provided between the deep groove bearing 51, the flat bearing 52, and the snap fastener 53. The deep groove bearing 51, the flat bearing 52, the snap fastener 53, and the gasket 54 are movably sleeved on the surface of the rotating rod 4. The deep groove bearing 51 abuts against the limiting ring 41. The deep groove bearing 51, the flat bearing 52, the snap fastener 53, and the gasket 54 are located in the inner cavity of one end of the housing 1 and are fastened. The function of the snap fastener 53 is to fasten the flat bearing 52, the snap fastener 53, and the gasket 54 and abut against the limiting ring 41, so as to prevent loosening and displacement. It also ensures the rotation of the rotating rod 4. By avoiding friction between the rotating rod 4 and the housing when the deep groove bearing 51 and the flat bearing 52 rotate, the temperature of the housing can be reduced.

[0023] The push rod 3 is provided with a push head 31 and a threaded connector 32 at both ends. The threaded connector 32 is threaded onto one end of the movable sleeve 6. The push rod 3 and the threaded connector 32 are adapted to the inner cavity of the connecting sleeve 11. The push head 31 is located on the outer side of one end of the connecting sleeve 11. By rotating the rotating rod 4, the movable sleeve 6 is moved in the inner cavity of the outer shell 1, thereby causing the push rod 3 to extend and retract.

[0024] In use, first install the needle roller 61 on the rotating rod 4 and install the bearing assembly 5 on one end of the rotating rod 4. Then, slide the movable sleeve 6 into the inner cavity of the outer shell 1. Then, the rotating rod 4 also enters the inner cavity of the outer shell 1. At the same time, the bearing assembly 5 will be sleeved at the port of the outer shell 1. Then, insert one end of the threaded connector 32 into the other end of the outer shell 1 and screw it onto one end of the movable sleeve 6. Then, put the connecting sleeve 11 on the push rod 3 and connect it to the other port of the outer shell 1. Finally, inject oil into the inner cavity of the outer shell 1.

[0025] When startup is required, the external electric gun is connected via connector 2, with the connecting end of the electric gun fitted onto one end of the rotating rod 4. The electric gun is then started, causing the rotating rod 4 to rotate within the deep groove bearing 51 and the flat bearing 52. The friction between the rotating rod 4 and the housing is reduced during rotation via the deep groove bearing 51 and the snap-fit ​​53, thus reducing the housing temperature. The threaded drive of the movable sleeve 6 extends and retracts within the inner cavity of the outer shell 1 via the needle roller 61. The three-sided needle roller 61 design significantly reduces friction with the housing, reducing temperature rise. The bearing assembly 5 and the movable sleeve 6, while reducing temperature rise, also prevent the oil in the inner cavity of the outer shell 1 from heating up. This reduced temperature rise also reduces oil consumption within the cavity. Finally, the movable sleeve 6 pushes the push rod 3 to move within the inner cavity of the connecting sleeve 11, causing the push head 31 to extend and retract.
