Description

Technical Field

[0001] The utility model relates to the technical field of hub production, in particular to a drilling mechanism for hub processing. Background Art

[0002] A hub is a cylindrical metal part that supports the tire inside the tire and is centered on the shaft. It is an essential part of an automobile. Since the hub needs to be installed on the vehicle shaft, drilling operations need to be performed on the hub to facilitate its fixation.

[0003] After retrieval, a patent with the publication number CN221047362U discloses a drilling device for hub processing. Through the setting of two groups of support panels and a support top plate, the motor mounting table is fixed. Then, through the setting of the motor mounting table, it is prevented that the working platform is unstable when the first motor is working. Furthermore, through the clamping and limiting of the hub by the limiting component, it is prevented that the hub moves during the drilling process of the hub, achieving the effect of improving the stability of the working platform and the quality of hub drilling at the same time.

[0004] This patent can ensure the stability during the drilling process, but there is still room for improvement. Since the holes on the hub are used for fixing and installing on the vehicle shaft, usually there are five or six of them, and most of these holes are distributed around the center of the hub. In this patent, the motor mounting table is fixed by using the support panel and the support top plate. Therefore, when the motor mounting table drives the drill bit to drill the hub, it can only drill a single fixed position on the surface of the hub. When drilling different positions, it is necessary to first remove the hub, adjust the position of the hub, re-clamp and fix it, and then perform the drilling operation, which reduces the processing efficiency of the hub.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] Example 1, referring to Figure 1 、 Figure 2 and Figure 3 A drilling mechanism for hub processing includes a workbench 1. A strip-shaped plate 2 is lapped on the upper surface of the workbench 1. Two positioning components are fixedly connected to the upper surface of the strip-shaped plate 2. A bracket 3 is fixedly connected to the right side of the workbench 1. A hydraulic push rod 4 is fixedly connected to the upper surface of the bracket 3. The output end of the hydraulic push rod 4 is fixedly connected to a drilling component. The hydraulic push rod 4 can drive the drill bit to descend for drilling operations.

[0026] The drilling component includes a disc 5. A first motor 6 is fixedly connected to the lower surface of the disc 5. The output end of the first motor 6 is fixedly connected to a round rod 7. The bottom end of the round rod 7 is fixedly connected to a support disc 8. A circular groove is opened on the lower surface of the disc 5. Four movable seats 9 are slidably connected to the inner wall of the circular groove. Four support rods 10 are fixedly connected to the upper surface of the support disc 8. The top ends of the four support rods 10 are respectively fixedly connected to the lower surfaces of the four movable seats 9. A circular frame 11 is fixedly connected to the lower surface of the support disc 8. The first motor 6 can drive the support disc 8 to rotate through the round rod 7. Since the support rods 10 are fixedly connected to the movable seats 9, the rotation of the support disc 8 will not be affected.

[0027] A rectangular hole is opened on the upper surface of the circular frame 11. A movable frame 12 is slidably connected to the inner wall of the rectangular hole. A transmission plate 13 is fixedly connected to the upper surface of the movable frame 12. An adjusting screw rod 14 is threadedly connected to the surface of the circular frame 11. The rear end of the adjusting screw rod 14 extends into the interior of the rectangular hole and is rotatably connected to the inner wall of the rectangular hole. A threaded hole adapted to the adjusting screw rod 14 is opened on the front surface of the transmission plate 13. The transmission plate 13 is threadedly connected to the adjusting screw rod 14 through the threaded hole. A second motor 15 is fixedly connected to the inner bottom wall of the movable frame 12. The output end of the second motor 15 is fixedly connected to a drill bit 16. A circular through hole adapted to the drill bit 16 is opened on the lower surface of the movable frame 12.

[0028] The second motor 15 can drive the drill bit 16 to rotate. At the same time, the hydraulic push rod 4 drives the drill bit 16 to descend, so as to drill the surface of the hub. And the first motor 6 drives the support disc 8 to rotate, which can adjust the position of the drill bit 16, with high flexibility. And rotating the adjusting screw rod 14 can adjust the position of the drill bit 16 from the center through the transmission plate 13, so as to process hubs with different hole distances.

[0029] Example 2: Referring to Figure 1 、Figure 4 and Figure 5 The positioning assembly includes a positioning frame 17. Two screw rods 18 are threadedly connected to the surface of the positioning frame 17. Two limiting grooves are formed in the inner bottom wall of the positioning frame 17. Limiting blocks 19 are slidably connected to the inner walls of the two limiting grooves. A connecting rod 20 is fixedly connected to the upper surface of the limiting block 19. The top end of the connecting rod 20 is fixedly connected to an arc-shaped top block 21. The opposite ends of the two screw rods 18 are respectively rotatably connected to the opposite surfaces of the arc-shaped top block 21. Rotating the two screw rods 18 can drive the two arc-shaped top blocks 21 to move towards the opposite surfaces, so as to tightly press the surface of the hub inside the positioning frame 17. And due to the limiting effect of the connecting rod 20 and the limiting block 19 on the arc-shaped top block 21, the arc-shaped top block 21 will not rotate. A third motor 22 is fixedly connected to the lower surface of the workbench 1. The output end of the third motor 22 is fixedly connected to a transmission rod 23. The top end of the transmission rod 23 is fixedly connected to the lower surface of the strip-shaped plate 2. A circular hole adapted to the transmission rod 23 is formed in the upper surface of the workbench 1. The third motor 22 can drive the strip-shaped plate 2 to rotate through the transmission rod 23, so as to improve the processing efficiency by using the two positioning assemblies and facilitate material loading and unloading.

[0030] Working principle: First, place the hub to be processed in the positioning frame 17. Rotate the two screw rods 18. The screw rods 18 can drive the two arc-shaped top blocks 21 to move towards the opposite surfaces. Due to the limiting effect of the connecting rod 20 and the limiting block 19, the arc-shaped top blocks 21 will move parallelly without rotation. Therefore, the two arc-shaped top blocks 21 can tightly press the surface of the hub. At this time, according to the position of the hole to be opened on the hub, rotate the adjusting screw rod 14, so that the adjusting screw rod 14 drives the movable frame 12 to move back and forth in the rectangular hole through the transmission plate 13. After the adjustment is completed, turn on the hydraulic push rod 4 to lower the drill bit 16. At the same time, the second motor 15 is started to drive the drill bit 16 to rotate, and drill the surface of the hub. During the drilling process, the movable frame 12 is supported by the top support disk 8 and the four support rods 10 and will not shift. Therefore, the drill bit 16 is more stable. After the first hole is processed, the first motor 6 is started, and the drill bit 16 is rotated to the next position where a hole needs to be opened through the round rod 7 and the support disk 8, and then the hole opening operation is carried out. After the hole opening operation is completed, the hydraulic push rod 4 drives the drilling assembly to rise. At the same time, the third motor 22 is started, and the strip-shaped plate 2 is driven to rotate through the transmission rod 23, so that the positioning frame 17 directly below the drilling assembly rotates to the left, and the right positioning frame 17 to be processed rotates to the left processing position, thus improving the processing efficiency of the hub.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
