[0002] The wheel hub is a metal component installed on the car to support the tire and fix it in its position. It is mainly used to bear and transmit all forces and torques between the car and the ground. Since the wheel hub is mostly made of metal, it is difficult to directly bear and transmit forces. Tires need to be installed on the wheel hub, and valves are installed on the wheel hub to achieve tire inflation and exhaust.

[0003] In order to install the valve, it is generally necessary to drill valve holes on the wheel hub. In order to ensure the stability and sealing of the valve during installation and operation, the valve hole is usually at a 90-degree angle to the end face of the wheel hub, while the end face of the valve hole on the wheel hub is mostly 45 degrees or 30 degrees. From a mechanical point of view, this is more conducive to the sealing of the valve, and can improve the stability of the valve during operation, reduce vibration and wear caused by improper angles, and extend the service life of the valve.

[0004] Currently, when machining hub valve holes, it is generally necessary to first adjust the drilling angle of the hub according to the angle of the hub end face, and then drill the hub, or drill manually. This makes the hub valve hole machining equipment less intelligent, not only extremely inconvenient to operate, but also easily leads to unstable machining quality of the valve holes, seriously affecting the machining efficiency and use effect of the valve holes.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0024] Example: Reference Figures 1-8A wheel hub valve hole processing equipment includes a workbench 1 and a mounting frame 11 installed on the workbench 1, and also includes: a lifting mechanism 12, which is arranged on the mounting frame 11, and the lifting mechanism 12 is provided with a detection mechanism 37, which is used to detect the angle of the end face of the wheel hub valve hole when moving along the lifting mechanism 12 toward the side of the wheel hub; a movable platform 3, which is arranged on the workbench 1, and is rotatably connected to the movable platform 3 with a fixed platform 4, and a first screw 7 is provided on the side of the movable platform 3 close to the fixed platform 4, and the first screw 7 is provided with an angle switching mechanism for adjusting the angle between the fixed platform 4 and the movable platform 3; a linkage mechanism, which is arranged between the lifting mechanism 12, the movable platform 3 and the mounting frame 11, and is connected to the first screw 7.

[0025] A movable rail 2 is provided on the workbench 1, and the movable platform 3 is located inside the movable rail 2. The movable rail 2 and the movable platform 3 are electrically driven to adjust the horizontal position between the movable platform 3 and the drill bit 36 ​​to ensure the accuracy of the wheel hub drilling position. A clamping assembly 5 is provided on the fixed platform 4. The specific structure of the clamping assembly 5 can refer to the technical solution in the prior art. Those skilled in the art can know it and will not go into details here. The clamping assembly 5 is arc-shaped to facilitate the stability of the wheel hub during the clamping process.

[0026] Reference Figure 1 、 Figure 2 and Figure 4 The lifting mechanism 12 includes a driving motor 121 fixedly connected to the mounting frame 11, the output end of the driving motor 121 is fixedly connected to a second screw 122, the second screw 122 is threadedly connected to a lifting seat 123, and a positioning rod 124 is fixedly connected to the mounting frame 11 and slidably connected to the lifting seat 123, wherein the lifting seat 123 is fixedly connected to a servo motor 35, and the output end of the servo motor 35 is fixedly connected to a drill bit 36.

[0027] When drilling a hole in the wheel hub, starting the drive motor 121 can drive the second screw 122 to rotate, thereby driving the lifting seat 123 to move along the direction of the second screw 122, and under the action of the positioning rod 124, the stability of the movement of the lifting seat 123 can be ensured. At the same time, starting the servo motor 35 can drive the drill bit 36 ​​to rotate, thereby realizing the processing of the wheel hub valve hole.

[0028] Reference Figure 4 and Figure 6The detection mechanism 37 includes a telescopic rod 371 symmetrically fixedly connected to the lifting seat 123 on the side close to the drill bit 36, the end of the telescopic rod 371 is fixedly connected to a universal ball 372, and the two sets of universal balls 372 are rotatably connected to the detection plate 373, and the telescopic rod 371 is fixedly connected to a mounting plate 374, and the mounting plate 374 is symmetrically fixedly connected to the side close to the detection plate 373 with a detection rod 375, wherein the telescopic rod 371 and the detection rod 375 are both elastic telescopic structures, and the drill bit 36 ​​is located at the center of the detection plate 373, the center of the detection plate 373 is a hollow structure, and the size of the hollow part of the detection plate 373 is larger than the size of the drill bit 36.

[0029] When the drill bit 36 ​​moves toward one side of the wheel hub, the detection plate 373 will first contact the end face of the wheel hub. If there is an angle between the end face of the wheel hub and the drill bit 36, the detection plate 373 will rotate, and at this time, the detection rod 375 on one side will be compressed. As the drill bit 36 ​​continues to move downward, the telescopic rod 371 will shrink, so that the drill bit 36 ​​and the detection rod 375 gradually approach each other. In this process, the angle of the wheel hub can be adjusted until the end face of the wheel hub and the drill bit 36 ​​are vertical. Then, the end face of the wheel hub can be drilled to realize the processing of the wheel hub valve hole. It should be explained that the universal ball 372 can also be hinged, and the direction of the hinge matches the inclination direction of the end face of the wheel hub.

[0030] Reference Figures 1-3 The angle switching mechanism includes a first support block 8 and a second support block 9 threadedly connected to the first screw 7. A limiting slot 6 is provided on the movable platform 3. The first screw 7 is located inside the limiting slot 6. The first support block 8 and the second support block 9 are slidingly connected to the limiting slot 6. The first support block 8 and the second support block 9 are arranged at an angle on the side close to each other, and the first support block 8 and the second support block 9 are arranged at an angle on the side close to the fixed platform 4. The inside of the limiting slot 6 is symmetrically fixed with a limiting rod 10.

[0031] During the drilling process, if there is an angle between the angle of the wheel hub end face and the drill bit 36, the first screw 7 rotates, driving the first support block 8 and the second support block 9 to move along the movable table 3, so that the first support block 8 or the second support block 9 moves to the bottom of the fixed table 4, thereby adjusting the angle of the fixed table 4 so that the wheel hub end face and the drill bit 36 ​​are perpendicular. In order to ensure the use effect of the valve hole after processing, the angles of the first support block 8 and the second support block 9 close to the fixed table 4 are thirty degrees and forty-five degrees respectively. That is, by supporting support blocks of different angles under the fixed table 4, the wheel hub can be at different angles during processing.

[0032] Reference Figure 1 and Figure 4The linkage mechanism includes a fixed frame 13 fixedly connected to the positioning rod 124, a rotating shaft 14 is rotatably connected to the fixed frame 13, a bevel gear set 15 that meshes with each other is provided between the end of the rotating shaft 14 and the second screw 122, a suction device 16 connected to the rotating shaft 14 is fixedly connected to the fixed frame 13, and a driving wheel 17 is fixedly connected to the end of the rotating shaft 14 away from the bevel gear set 15.

[0033] During the lifting process of the drill bit 36, the rotating shaft 14 can be driven to rotate through the bevel gear set 15. It should be explained that the rotation speed of the rotating shaft 14 can be adjusted according to the size ratio between the bevel gear sets 15, so that it can drive the suction device 16 and make the suction device 16 generate a certain negative pressure, which is sufficient to absorb the debris generated during the drilling process.

[0034] Reference Figure 1 、 Figure 4 、 Figure 5 and Figure 8 A synchronization groove 18 is provided on the side wall of the workbench 1, and a slide 19 is slidably connected inside the synchronization groove 18. A connecting piece 20 is fixedly connected between the slide 19 and the movable platform 3. A positioning groove 21 is provided on the slide 19, and a first slider 22 is slidably connected inside the positioning groove 21. The first slider 22 is rotatably connected to the side of the first screw 7 close to the first screw 7. The end of the first screw 7 is fixedly connected to the driving gear 24 that meshes with the first driven gear 25 and the second driven gear 26. An adjusting rod 23 connected to the first slider 22 is fixedly connected to the slide 19, wherein the adjusting rod 23 is connected to the limit rod 10 and the detection rod 375 through a pipe, and the size between the first driven gear 25 and the second driven gear 26 is larger than that of the driving gear 24.

[0035] When the position of the movable platform 3 is adjusted by the movable rail 2 (adjusting the horizontal position between the wheel hub and the drill hole), the first driven gear 25, the second driven gear 26 and the driving gear 24 will move synchronously under the action of the connecting member 20. During the drilling process, the extension length of the adjusting rod 23 is adjusted according to the angle of the detection plate 373 and the compression of the limiting rod 10 in different directions. It should be explained that the adjusting rod 23 includes two sets of sealed cavities, and the two sets of sealed cavities are respectively connected to the detection rod 375 and the limiting rod 10 in different directions. That is to say, if the detection plate 373 is in the water In the flat state, the first driven gear 25 and the second driven gear 26 do not mesh with the drive gear 24, that is, there is no need to adjust the angle of the wheel hub. If the detection plate 373 is in an inclined state, and the first driven gear 25 or the second driven gear 26 is adjusted to mesh with the drive gear 24, the angle of the wheel hub is adjusted until the detection plate 373 is in a horizontal state, and when the first support block 8 or the second support block 9 compresses the limit rod 10 to a certain size, the first driven gear 25 or the second driven gear 26 is stopped from meshing with the drive gear 24, thereby ensuring the stability of the wheel hub during drilling.

[0036] Reference Figure 4 and Figure 8 The first slider 22 is rotatably connected to the side away from the first driven gear 25 and the second driven gear 26, and a linkage belt 28 is wound around the two groups of linkage wheels 27, and the linkage belt 28 is arranged crosswise. It also includes a driven wheel 29 fixedly connected to one of the groups of linkage wheels 27, a fixed frame 30 on the side of the mounting frame 11 close to the driven wheel 29, and a second slider 31 is slidably connected to the inside of the fixed frame 30. A spring 32 is fixedly connected between the second slider 31 and the fixed frame 30. A tensioning wheel 33 is rotatably connected to the second slider 31, and a belt 34 is sleeved between the driving wheel 17, the tensioning wheel 33 and the driven wheel 29.

[0037] The cross setting of the linkage belt 28 is a conventional means in the prior art, which can enable the two sets of linkage wheels 27 to rotate in different directions, thereby adjusting the rotation direction of the first screw 7. During the movement of the movable platform 3, under the action of the spring 32, the belt 34 can always be kept taut to ensure the stable rotation of the driven wheel 29.

[0038] Reference Figure 1 、 Figure 4 、 Figure 6 and Figure 7A collecting box 38 is fixedly connected to the mounting frame 11, and a connecting pipe 39 is connected to the air inlet end of the collecting box 38 and the air suction device 16. The side of the collecting box 38 away from the connecting pipe 39 is connected to the adsorption tube 40, and a guide frame 41 is fixedly connected to the detection plate 373. The adsorption tube 40 is directed toward the center position of the detection plate 373 through the guide frame 41. A sealing frame 42 is fixedly connected to the side of the collecting box 38 near the connecting pipe 39, and a filter hole 43 is provided on the side of the sealing frame 42 near the adsorption tube 40. A driving rod 44 is fixedly connected to the bottom of the collecting box 38, and a scraper 45 is fixedly connected to the end of the driving rod 44, wherein the scraper 45 is arranged at an angle, and the scraper 45 is in contact with the side of the sealing frame 42 near the filter hole 43, and the driving rod 44 is connected to the telescopic rod 371 through a pipe.

[0039] During the drilling process, the suction device 16 will be driven to absorb the debris at the drilling position into the collection box 38 through the connecting pipe 39 and the adsorption tube 40. It should be explained that since the thickness of the hub end face is generally small, the drilling speed is generally faster. Compared with drilling thicker materials, the loss of lifting speed is smaller and the stagnation time is shorter. That is, during this process, the suction device 16 is basically in a continuous working state. When the drill bit 36 ​​moves downward, the telescopic rod 371 will be in a compressed state, thereby driving the drive rod 44 to extend outward and driving the scraper 45 to move to the upper filter hole 43. After the drilling is completed, the drill bit 36 ​​moves upward, and the suction device 16 works in reverse, that is, blowing air to the filter hole 43, and then the scraper 45 moves to the initial position, thereby cleaning the debris at the filter hole 43. In addition, the debris remaining on the drill bit 36 ​​can also be cleaned through the adsorption tube 40 to facilitate the subsequent use of the drill bit 36.

[0040] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
