Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing technology, and in particular to a processing device for valve holes in automobile wheel hubs. Background Technology

[0002] Automobile wheel hubs typically have valve core mounting holes (hereinafter referred to as valve holes). These valve holes are usually machined using a drilling machine. In existing valve hole machining equipment, such as the automatic machining equipment and method for wheel hub valve core holes disclosed in patent CN104889447A, a first motor drives a first drill bit to rotate, thereby machining the valve hole on the wheel hub. However, the wheel hub is placed horizontally on a servo rotating device, and the motor and drill bit are also horizontally positioned. Therefore, the drilled valve hole is also horizontal, i.e., along the radial direction of the wheel hub.

[0003] However, in reality, in order to facilitate the installation of valve stems and tire inflation, valve holes are generally inclined at a certain angle (usually 30°-45°) to the wheel hub axis, and almost none are set radially. Obviously, the above-mentioned equipment cannot truly meet the processing requirements of valve holes. Therefore, it is necessary to redesign a valve hole processing equipment to meet the processing requirements of valve holes. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model discloses a processing device for valve holes in automobile wheel hubs, including a worktable, a linear module, a geared motor, a drill bit, an angle adjustment mechanism, and a wheel hub positioning mechanism. The linear module is inclinedly arranged on the worktable, the geared motor is arranged on the slider of the linear module, the drill bit is coaxially arranged with the drive shaft of the geared motor, the angle adjustment mechanism is arranged on the worktable and is connected to the linear module, and the wheel hub positioning mechanism is arranged on the worktable and located on one side of the linear module.

[0005] Furthermore, the angle adjustment mechanism includes a rotating support, a rotating shaft, an angle indicator, and a pointer. The rotating support is supported on both sides of the rear end of the linear module. The rotating shaft is rotatably connected to the rotating supports on both sides and connected to the rear end of the linear module at its middle position. The angle indicator is fixedly mounted on one of the rotating supports, and the pointer is fixedly mounted on the end of the rotating shaft on the same side as the angle indicator.

[0006] Furthermore, both the rotating shaft and the pointer are located in the same straight line direction as the drill bit.

[0007] Furthermore, the angle indicator has a fan-shaped disk structure, with 0-90° scale lines evenly distributed on its fan surface in an arc manner.

[0008] Furthermore, a positioning seat and a positioning rod are provided on the worktable at the bottom of the linear module. The positioning seat is provided with multiple arc-shaped buckles at equal intervals along the horizontal direction. One end of the positioning rod is rotatably connected to the bottom of the linear module, and the other end is provided with a corner portion, which is engaged with the arc-shaped buckles.

[0009] Furthermore, the hub positioning mechanism includes a bracket, a cylinder, and a positioning pressure plate. The bracket is supported on the worktable, the cylinder is longitudinally positioned on the top of the bracket with its piston rod extending downward, and the positioning pressure plate is horizontally positioned at the end of the piston rod.

[0010] Furthermore, two positioning blocks are provided on the workbench at the lower side of the support, and the two positioning blocks are symmetrically and inclined along the straight line where the drill bit is located.

[0011] Furthermore, the positioning pressure plate is a circular structure with multiple support beams in the middle.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0025] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1-2 As shown, the processing device for automotive wheel hub valve holes in this embodiment includes a worktable 1, a linear module 2, a geared motor 3, a drill bit 4, an angle adjustment mechanism, and a wheel hub positioning mechanism. The linear module 2 is inclinedly mounted on the worktable 1, the geared motor 3 is mounted on the slider of the linear module 2, and the drill bit 4 is coaxially mounted with the drive shaft of the geared motor 3. The linear module 2 can drive the geared motor 3 to move back and forth, and the geared motor 3 can drive the drill bit 4 to rotate. The linear module 2, the geared motor 3, and the drill bit 4 all adopt existing technologies in the art.

[0027] An angle adjustment mechanism is set on the workbench 1 and connected to the linear module 2. A hub positioning mechanism is set on the workbench 1 and located on one side of the linear module 2.

[0028] The angle adjustment mechanism includes a rotating support 5, a rotating shaft 6, an angle indicator 7, and a pointer 8. The rotating support 5 is supported on both sides of the rear end of the linear module 2. The rotating shaft 6 is rotatably connected to the rotating supports 5 on both sides and connected to the rear end of the linear module 2 at its middle position. The angle indicator 7 is fixedly mounted on one of the rotating supports 5. The pointer 8 is fixedly mounted at the end of the rotating shaft 6 on the same side as the angle indicator 7.

[0029] like Figure 3 As shown, the angle indicator 7 has a fan-shaped disk structure, with scale lines of 0-90° evenly distributed in an arc on its fan surface.

[0030] Combination Figure 4 and Figure 5 As shown, a positioning seat 9 and a positioning rod 10 are provided on the workbench 1 at the bottom of the linear module 2. Multiple arc-shaped buckles 11 are equidistantly spaced along the horizontal direction on the positioning seat 9. One end of the positioning rod 10 is rotatably connected to the bottom of the linear module 2, and the other end has a corner portion 12, which engages with the arc-shaped buckles 11. The arc-shaped buckles 11 can be made of elastic plastic to firmly hold the corner portion 12.

[0031] By adjusting the engagement position of the positioning rod 10 with different arc-shaped buckles 11, the tilt angle of the positioning rod 10 can be changed, thereby enabling the linear module 2 to be adjusted in multiple angles to meet the processing requirements of valve holes at different angles.

[0032] The wheel hub positioning mechanism includes a bracket 13, a cylinder 14, and a positioning pressure plate 15. The bracket 13 is supported on the worktable 1. The cylinder 14 is longitudinally positioned on the top of the bracket 13 and its piston rod extends downward. The positioning pressure plate 15 is horizontally positioned at the end of the piston rod.

[0033] Two positioning blocks 16 are also provided on the workbench 1 below the support 13. The two positioning blocks 16 are symmetrically and inclined along the straight line where the drill bit 4 is located.

[0034] like Figure 6 As shown, the positioning pressure plate 15 is a circular structure with multiple support beams in the middle.

[0035] When machining the valve hole, first place the wheel hub horizontally on the workbench 1 with the side that needs to be machined facing upwards. At the same time, make one side of the wheel hub abut against one side of the two positioning blocks 16. The two inclined positioning blocks 16 have strong adaptability and can meet the positioning requirements of wheel hubs of different specifications.

[0036] After the wheel hub is pressed against the positioning block 16, the cylinder 14 drives the positioning pressure plate 15 to move downward, so that the positioning pressure plate 15 presses tightly against the surface of the wheel hub, thereby achieving the positioning of the wheel hub.

[0037] Then, adjust the tilt angle of the linear module 2 according to the machining angle of the valve hole. When the linear module 2 is rotated, the rotating shaft 6 and the pointer 8 will rotate at the same time. Since the rotating shaft 6 and the pointer 8 are both located in the same straight line direction as the drill bit 4, the angle indicated by the pointer 8 is the tilt angle of the drill bit 4, and thus the machining angle of the valve hole can be determined.

[0038] After the machining angle is determined, the linear module 2 drives the geared motor 3 and the drill bit 4 to move towards the hub side, and the rotating drill bit 4 machines an inclined valve hole on the side of the hub.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
