DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] The directional terms used in the detailed description are intended solely to facilitate understanding of the technical solutions described herein by those skilled in the art based on the visual orientation shown in the accompanying drawings. Unless otherwise specified or limited, the terms "dispose," "install," and "connect" are to be interpreted broadly, and those skilled in the art will understand their specific meanings in this utility model based on the specific circumstances.

[0029] like Figures 1 to 9 As shown, a device for quickly removing pneumatic shaft bearings includes a base 2, to which a telescopic clamping mechanism 1 is fixedly connected. The telescopic clamping mechanism 1 includes a screw 101 fixedly connected to the base, and two groups of oppositely placed slides 103 are fixedly connected to the top of the screw 101. Each group of slides 103 is provided with four slide grooves 1031, and a slide limiting hole 1032 is provided on one side of the slide groove 1031. A top plate 102 is slidably connected in the slide groove 1031. Multiple top plates 102 can increase the contact area between the top plate and the bearing, make the force more uniform, and facilitate removal without damaging the bearing. A connecting post 1022 is fixedly connected between the two opposing top plates 102. The connecting post 1022 is slidably connected to the slide stop hole 1032. A rotating handle 106 is provided at the bottom of the inner slide 103, which is rotatably connected to the lead screw 101. The rotating handle 106 includes a rotating disk 1061 with four arcuate through-holes 1062. The protruding end of the inner top plate 102 passes through the inner slide stop hole 1032 and slidably connects to the arcuate through-hole 1062. The advantage of this design is that the top plates 102 can be synchronously extended and retracted by rotating the rotating disk 1061. A handle 1063 is fixedly connected to one side of the rotating disk 1061, and a plurality of limit holes 1064 are opened on one side of the handle 1063.

[0030] like Figures 7 and 8As shown, a spring 1104 is fixedly connected to the limiting hole 1064, and an arc-shaped groove 1015 is provided on the lead screw 101 opposite the limiting hole 1064. A matching steel ball 105 is provided between the arc-shaped groove 1015 and the spring 1104. The advantage of this design is that when the rotating handle 106 is rotated, due to the action of the spring 1104 and the steel ball 105, the rotating handle 106 will not return to its original position when the rotation stops. It can only return to its original position by rotating in the opposite direction, preventing the telescopic clamping mechanism 1 from slipping off the inner diameter of the bearing during operation. A fixed limit 107 fixedly connected to the lead screw 101 is provided on one side of the arc-shaped groove 1015, and the fixed limit 107 is abutted against the handle 1063. The top plate 102 is "L"-shaped, and a through delivery pipe 1021 is provided inside the top plate 102. The advantage of this design is that the short end of the "L" shape can directly contact the bearing, making it convenient for the delivery pipe 1021 on the top plate 102 to transport the rust remover to the position where the outer diameter of the bearing contacts the inside of the air shaft.

[0031] like Figure 3 As shown, one side of the screw 101 is provided with a thread 1011. A groove 1012 is formed on one side of the thread 1011, and a pipe mounting hole 1013 is provided within the groove 1012. On the other side of the screw 101, two sets of through holes 1014 are formed. These two sets of through holes 1014 are located within the two sets of slides 103, respectively. Each set of through holes 1014 has four openings, corresponding to the four delivery pipes 1021 on the top plate 102. A storage tank 202 is fixedly connected to one side of the bottom of the base 2. A sealing cover 201 is fixedly connected to the base 2 above the storage tank 202. The rust remover in the storage tank 202 can be replenished by opening and closing the sealing cover 201. A pump 203 is fixedly connected to the bottom of the base 2 on one side of the storage tank 202. The inlet of the pump 203 is sealed with the storage tank 202, and the outlet of the pump 203 is sealed with a hose 204.

[0032] One side of the hose 204 is sealed. The hose 204 passes through the groove 1012 and enters the pipe mounting hole 1013. A liquid dispensing tube 2041 is sealedly connected to the hose 204 at the through hole 1014. The liquid dispensing tube 2041 is a soft rubber tube with four liquid outlets, one side of which is sealedly connected to the delivery pipe 1021. This design allows the soft rubber tube to remain connected to the delivery pipe 1021 on the top plate 102 during expansion and contraction, preventing it from becoming disconnected. The hose 204, the liquid dispensing tube 2041, and the delivery pipe 1021 are interconnected.

[0033] A round table 206 is fixedly connected to the upper part of the base 2, and a handle 205 is fixedly connected to the screw 101 passing through one side of the base 2. One side of the handle 205 is against the bottom of the base 2. By rotating the handle 205 to drive the screw 101, the telescopic clamping mechanism 1 can be raised and lowered.

[0034] Working process: Place the pneumatic shaft with bearings vertically on the utility model, pass the slide 103 on the telescopic clamping mechanism 1 through the inner diameter of the bearing, so that the two slides 103 are located on both sides of the bearing, rotate the handle 106, and the arc-shaped through hole 1062 on the rotating disk 1061 drives the top plate 102 to extend outward, and stop moving when the top plate 102 moves to be consistent with the outer diameter of the bearing.

[0035] Turn handle 205, pressing one side of the air shaft against the rounded platform 206. Continue to slowly turn handle 205 to remove the bearing from the air shaft. If rust is detected at the contact point between the air shaft and the outer diameter of the bearing, pump 203 can be used to deliver rust remover from storage tank 202 through a hose and delivery pipe 1021 on top plate 102 to the contact point between the air shaft and the outer diameter of the bearing to remove the rust. After waiting for a few minutes depending on the contact area between the bearing and the air shaft, turn handle 205 again to remove the bearing from the air shaft.

[0036] Finally, although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
