[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1As shown, a motorcycle wheel hub bearing device comprises a base 1, a positioning shaft 4 is installed at the middle position of the upper part of the base 1, and a plurality of hydraulic cylinders 8 are arranged on the upper part of the base 1, and a positioning block 9 is connected to the piston rod of the hydraulic cylinder 8. The plurality of hydraulic cylinders 8 are evenly distributed with the positioning shaft 4 as the center. The positioning shaft 4 is inserted into the shaft hole of the wheel hub 54, and the wheel hub 54 is centrally positioned by the positioning shaft 4. The hydraulic cylinder 28 controls the extension of its piston rod to drive the positioning block 9 to move toward the center, and the positioning block 9 is pressed on the outer periphery of the wheel hub 54, thereby completing the fixing of the wheel hub 54.

[0029] like Figure 2 , Figure 7 , Figure 8 As shown, a side plate 2 is connected to each of the left and right sides of the upper part of the base 1, a top plate 3 is connected to the upper end of the side plate 2, a hydraulic cylinder 5 is arranged at the lower part of the top plate 3, a pressure plate 6 is connected to the lower end of the piston rod of the hydraulic cylinder 5, a clamping mechanism 7 is arranged at each of the left and right sides of the pressure plate 6, a support block 27 is arranged at the upper part of the pressure plate 6, the clamping mechanism 7 comprises a mounting plate 23, a cylinder 24 is mounted on the inner side of the mounting plate 23, a clamping block 25 is connected to the piston rod of the cylinder 24, a mounting frame 29 is connected to the upper part of the mounting plate 23, a part of the mounting frame 29 is located in the support block 27, a guide hole is opened on the support block 27, and a support rod 28 is located at The guide hole includes a vertical guide hole 32 and a horizontal guide hole 33. The lower end of the vertical guide hole 32 is connected to the outer end of the horizontal guide hole 33. A spring 26 is arranged in the horizontal guide hole 33. One end of the spring 26 is connected to the inner end of the horizontal guide hole 33. The other end of the spring 26 is connected to the push block 30. A receiving groove 52 is provided at the lower part of the pressure plate 6. The receiving groove 52 is located above the mounting plate 23. A limit block 10 is installed on the inner side of the side plate 2. A guide groove 11 is provided on the inner side of the limit block 10. A wire slope 35 is provided on the upper part of the guide groove 11. The wire slope 35 is inclined inwardly and upwardly.

[0030] like Figure 1 , Fig. 9 As shown, the upper end of the bearing 53 abuts against the lower end surface of the pressure plate 6, and the cylinders 1 24 on both sides synchronously control the extension of the piston rod, and the clamping blocks 25 on both sides clamp the bearing 53 to complete the positioning and fixing of the bearing 53, so that the position of the bearing 53 corresponds to the position of the mounting hole on the lower wheel hub 54. Under the action of the spring 1 26, the push block 30 has the force to push the support rod 28 outward, but because the outer end of the mounting plate 23 abuts against the inner side of the limit block 10, the position of the clamping mechanism 7 remains fixed. At this time, the hydraulic cylinder 1 5 controls its piston rod to extend, and when the pressure plate 6 moves downward, it will drive the clamping mechanism 7 to move downward synchronously. Under the clamping and fixing of the clamping mechanism 7, the bearing 53 can be accurately pressed into the mounting hole of the wheel hub 54 in a horizontal state.

[0031] As the piston rod of hydraulic cylinder 15 continues to extend, Fig.10As shown, the clamping mechanism 7 moves to the position where the guide groove 11 on the limit block 10 is located. At this time, the push block 30 pushes the support rod 28 to move outward in the horizontal guide hole 33, and the support rod 28 reaches the connection between the vertical guide hole 32 and the horizontal guide hole 33, so that the mounting plate 23 moves outward so that the outer end enters the guide groove 11. The clamping block 25 is separated from the bearing 53, preparing for pressing the bearing 53 completely into the mounting hole of the hub 54.

[0032] like Fig.11 As shown, the piston rod of the hydraulic cylinder 15 is further extended, so that the mounting plate 23 contacts the bottom of the guide groove 11, and the guide groove 11 blocks the mounting plate 23. At this time, the support rod 28 can move upward along the vertical guide hole 32, that is, relative displacement can occur between the mounting plate 23 and the pressure plate 6. The pressure plate 6 continues to move downward to press the bearing 53 into the mounting hole of the wheel hub 54, while the mounting plate 23 stops moving and is received in the receiving groove 52. The distance between the two receiving grooves 52 is greater than the diameter of the bearing 53, so that the pressure plate 6 can be completely in contact with the upper end surface of the bearing 53, which also allows the bearing 53 to be evenly stressed, so that it will not deflect when pressed into the mounting hole.

[0033] After the bearing 53 is pressed, the hydraulic cylinder 5 controls its piston rod to retract, thereby driving the pressure plate 6 to move upward. During the rising process of the pressure plate 6, the mounting plate 23 first remains stationary and escapes from the storage groove 52. After the support rod 28 moves to the connection between the vertical guide hole 32 and the horizontal guide hole 33, as the pressure plate 6 continues to rise, the mounting plate 23 also rises together. The mounting plate 23 rises in the guide groove 11. After the mounting plate 23 contacts the wire slope 35, the end of the mounting plate 23 moves along the wire slope 35, causing the mounting plate 23 to move inward. After the mounting plate 23 escapes from the guide groove 11, the outer end of the mounting plate 23 abuts against the inner side of the limit block 10.

[0034] In order to ensure that the position of the mounting plate 23 is fixed in the initial state, a second cylinder 34 is provided on the support block 27, and the lower end of the piston rod of the second cylinder 34 is connected to a clamping block 31. The second cylinder 34 controls the extension of its piston rod so that the clamping block 31 moves downward to clamp the support rod 28, thereby fixing the position of the mounting plate 23 and ensuring that the bearing 53 does not move and deviate in the initial state.

[0035] like Figure 3As shown, a trigger mechanism 1 36 is provided at the position above the guide groove 11 on the inner side of the limit block 10, and the trigger mechanism 1 36 is electrically connected to the cylinder 2 34. Before the mounting plate 23 moves to the position where the guide groove 11 is located, the mounting plate 23 contacts the trigger mechanism 1 36, so that the trigger mechanism 1 36 sends a signal to the cylinder 2 34 to operate. The cylinder 2 34 controls its piston rod to move upward, so that the block 31 leaves the support rod 28, thereby releasing the fixing of the mounting plate 23, so that the mounting plate 23 can move outward into the guide groove 11.

[0036] like Figure 4 As shown, the trigger mechanism 1 36 includes a sliding groove provided on the limit block 10, a sliding block 38 is slidably arranged in the sliding groove, a spring 2 41 is connected between the inner wall of the sliding groove and the sliding block 38, a micro switch 39 is installed on the inner wall of the sliding groove, a trigger block 40 is connected to one end of the sliding block 38 close to the micro switch 39, and the micro switch 39 is electrically connected to the cylinder 2 34. When the mounting plate 23 moves along the inner side of the limit block 10, it contacts the sliding block 38 and presses it inward, and the trigger block 40 contacts the micro switch 39, so that the micro switch 39 sends a signal to the cylinder 2 34.

[0037] An airbag 22 is provided at the lower part of the mounting plate 23, and an air pump is provided inside the mounting plate 23, and the air pump is connected to the airbag 22. A trigger mechanism 2 37 is provided at the lower part of the mounting plate 23, and the trigger mechanism 2 37 is electrically connected to the air pump. When the mounting plate 23 moves to the bottom of the guide groove 11, the trigger mechanism 2 37 contacts the bottom of the guide groove 11, thereby sending a signal to the air pump in the mounting plate 23 to operate, and the air pump inflates the airbag 22. The airbag 22 is inflated and expanded, and the airbag 22 contacts the upper surface of the wheel hub 54, thereby protecting the wheel hub 54 and preventing the surface of the wheel hub 54 from being crushed.

[0038] like Figure 5 , Figure 6As shown, a mounting ring 12 is provided at the upper part of the base 1 at the position of the outer periphery of the positioning shaft 4, an annular cavity 42 is provided in the mounting ring 12, an air suction hole 43 is provided at the upper part of the annular cavity 42, and the upper end of the air suction hole 43 is connected to the upper end of the mounting ring 12, a ventilation cavity 45 is provided in the base 1, a connecting pipe 44 is connected between the ventilation cavity 45 and the annular cavity 42, one end of the ventilation cavity 45 is connected to the side of the base 1, a rotating frame 47 is provided in the ventilation cavity 45, a rotating shaft 48 is rotatably provided in the rotating frame 47, a fan blade 50 is installed on the rotating shaft 48, and a driving mechanism for driving the rotating shaft 48 to rotate is also included. A filter screen 46 is provided at a position between the connecting pipe 44 and the fan blade 50 in the ventilation cavity 45. A mounting port is provided on the side of the base 1, and the position of the mounting port corresponds to the filter screen 46, and the filter screen 46 is installed and replaced through the mounting port. The mounting port is usually kept closed. The driving mechanism includes a transmission shaft 18, the lower end of the transmission shaft 18 extends into the ventilation chamber 45 and is connected to a driving bevel gear 51, the end of the rotating shaft 48 away from the fan blades 50 is connected to a driven bevel gear 49, the driven bevel gear 49 is meshed with the driving bevel gear 51, and a mounting groove 17 is opened in the side plate 2 close to the ventilation chamber 45. The transmission shaft 18 is rotatably set in the mounting groove 17, and the upper end of the transmission shaft 18 is connected to the driven gear 19. A driving motor 20 is arranged at a position above the transmission shaft 18 in the mounting groove 17, and the driving motor 20 is drivingly connected to the driving gear 21, and a transmission mechanism is arranged between the driving gear 21 and the driven gear 19. A mounting rod 14 is connected to the side of the piston rod of the hydraulic cylinder 5, a mounting block 15 is mounted on the mounting rod 14, a transmission gear 16 is rotatably mounted on the mounting block 15, an opening 13 is provided on the side of the mounting groove 17, the transmission gear 16 passes through the opening 13 and extends into the mounting groove 17, and the transmission gear 16 can mesh with the driving gear 21 and the driven gear 19.

[0039] In the initial state, the transmission gear 16 is meshed with the driving gear 21 and the driven gear 19, and the transmission between the driving gear 21 and the driven gear 19 is carried out through the transmission gear 16, so that the transmission shaft 18 rotates. The transmission shaft 18 then drives the rotating shaft 48 to rotate through the cooperation of the driving bevel gear 51 and the driven bevel gear 49. The rotating shaft 48 rotates with the fan blades 50, so that suction is generated at the suction hole 43 to suck in dust and other impurities, and the installation environment is cleaned. When the bearing 53 is pressed in, the extension of the piston rod of the hydraulic cylinder 15 will drive the installation rod 14 to move downward, thereby causing the transmission gear 16 to move downward, and the transmission gear 16 will be separated from the driving gear 21 and the driven gear 19, so that the transmission shaft 18 stops rotating, and the dust suction is stopped, thereby avoiding the impurities being sucked into the installation place due to the suction during the pressing process, and reducing the impact of impurities on the installation.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
