Description

Technical Field

[0001] This utility model belongs to the field of wheel rim technology, specifically relating to a wheel rim drilling and processing device. Background Technology

[0002] In the wheel rim manufacturing industry, the drilling process is a crucial step in ensuring the fit and compatibility of wheel rim installation. Its machining accuracy directly affects the assembly quality and safety of the wheel rim. Currently, many commonly used wheel rim drilling devices in the industry suffer from poor positioning stability and insufficient adjustment flexibility. Traditional devices typically use simple clamps to fix the wheel rim, which are difficult to adapt to different wheel rim specifications. Changing the wheel rim model requires readjusting the clamps, which is time-consuming and labor-intensive, severely impacting production efficiency. Meanwhile, existing devices rely heavily on manual operation when adjusting rim height and angle, which not only makes it difficult to control precision but also easily leads to drilling position deviation due to operational errors, resulting in a higher scrap rate. In addition, the positioning structure design of some devices is unreasonable. During the drilling process, the movement of the drill bit is prone to spatial interference with the positioning components, limiting the flexibility of the drilling position and failing to meet the drilling requirements of complex rims.

[0014] like Figure 1-2 As shown, the rim drilling device includes a base 1, a rim positioning platform 2 on one side of the base 1, and a slide rail 3 on the other side. A slide table 4 is mounted on the slide rail 3, and a drill 5 is mounted on the slide table 4. The drill bit of the drill 5 is horizontally positioned and faces the slide table 4. The slide table 4 is driven to move on the slide rail 3 by a translation drive mechanism. A turntable 6 is mounted on the rim positioning platform 2. The turntable 6 is driven to rotate by a rotation drive mechanism and to rise and fall by a lifting drive mechanism. A central column 7 is detachably connected to the upper center of the turntable 6. Clamping plates 8 are respectively provided on both sides of the turntable 6, and the clamping plates 8 are driven to move up and down by a vertical movement drive mechanism. The rim 22 is fitted onto the central column 7 for positioning. As the slide table 4 moves, the drill bit of the drill 5 gradually approaches the rim 22 to drill. When it is necessary to move the rim 22 up and down or rotate it, the clamping plates 8 rise to release the rim 22.

[0015] Furthermore, the up-and-down movement drive mechanism includes a cylinder 9, which is mounted on the rim positioning platform 2. The output shaft of the cylinder 9 is fixedly connected to a lifting plate 10. The lifting plate 10 has an insertion port 11, through which the clamping plate 8 moves. Guide holes are provided at both ends of the lifting plate 10, and guide rods 12 are inserted into the guide holes. The guide rods 12 are fixedly connected to the rim positioning platform 2. The cylinder 9 drives the lifting plate 10 to move up and down, thereby causing the clamping plate 8 to move up and down, thus clamping or releasing the rim 22.

[0016] Furthermore, the lifting drive mechanism includes a servo motor 13 and a lead screw 14. The lead screw 14 is located below and rotatably connected to the rim positioning platform 2. The servo motor 13 drives the lead screw 14 to rotate. A lead screw pair 15 is mounted on the lead screw 14, and the lead screw pair 15 is rotatably connected to a movable plate 16. Several lifting rods 17 are fixedly connected to the rim positioning platform 2. The movable plate 16 is provided with guide sleeves for the lifting rods 17 to move through. The rotation drive mechanism includes a rotary motor 19 mounted on the movable plate 16. The output shaft of the rotary motor 19 is fixedly connected to a turntable 6. The servo motor 13 drives the lead screw 14 to rotate, causing the movable plate 16 to move up and down, thereby adjusting the height of the turntable 6 and the height of the rim 22. The rotary motor 19 drives the turntable 6 to rotate, adjusting the angle of the rim 22. The rotary motor 19 is preferably an indexing motor, which can precisely control the rotation angle.

[0017] Furthermore, the central column 7 is connected to the turntable 6 by several bolts. The size of the central column 7 can be changed or adjusted as needed.

[0018] Furthermore, the center post 7 is provided with positioning parts 20 at its upper and lower ends, forming a diameter reduction section 21 between the positioning parts 20. The upper and lower ends of the positioning parts 20 are each provided with inclined guide surfaces 22. After the rim 22 is fitted onto the center post 7, the positioning parts 20 position the rim 22. The center post 7 can be made of materials such as rubber or wood. The diameter reduction section 21 provides space for the drill bit to move.

[0019] Furthermore, the translation drive mechanism includes a drive motor 23 and a horizontal lead screw 24. The horizontal lead screw 24 is rotatably mounted on the base 1, and a horizontal lead screw nut 25 is provided on the horizontal lead screw 24. The horizontal lead screw nut 25 is fixedly connected to the slide table 4, and the drive motor 23 drives the horizontal lead screw 24 to rotate. The drive motor 23 is preferably a servo motor. The cooperation between the drive motor 23 and the horizontal lead screw 24 improves the accuracy of the slide table 4's movement position, thereby accurately controlling the drilling rig 5. The drilling rig 5 is existing technology and generally includes a drill bit and a motor that controls the rotation of the drill bit.
