The wheel hub is a cylindrical metal component with the inner profile of the tire supporting the tire and the center mounted on the shaft. It is also called a rim, steel ring, wheel and tire bell. There are many types of wheel hubs depending on the diameter, width, molding method and material. It is an important component connecting the brake drum (brake disc), wheel disc and half-axle.

[0003] For example, patent number CN 221517509 U discloses a forged wheel hub processing fixture, which relates to the field of wheel hub processing technology, including a processing table, on which a mounting groove, two mounting plates and a sliding disc are provided, a telescopic component is provided in the mounting groove, the telescopic component is connected to a placement table, a first motor is provided on one mounting plate, a second motor is provided on the other mounting plate, the second motor is connected to an electric cylinder, the electric cylinder and the first motor are respectively connected to two V-shaped clamping blocks arranged opposite each other, a rubber pad is provided on the V-shaped clamping block, a fixing component is provided on the disc and the disc is connected to a driving component; this device automatically completes the clamping and flipping process of the wheel hub, and does not require manual intervention and adjustment during the processing process. At the same time, different clamping methods can be selected as needed to clamp different surfaces of the wheel hub, and the fixture does not hinder the subsequent processing process of different surfaces of the wheel hub.

[0004] In the prior art, by setting a telescopic component and a driving component, the wheel hub can be simply clamped without manual intervention, which improves the convenience of work. However, the overall use still has the following problems: during use, when the wheel hub is clamped, due to the lack of internal support, the wheel hub will be deformed during the subsequent clamping process. When the milling machine is working, it will become loose due to vibration, causing the wheel hub position to shift, affecting the accuracy of milling; secondly, when the existing clamp is clamping the wheel hub, the clamp cannot fit the curvature of the wheel hub for clamping, and the overall adaptability of the clamp is poor. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a forged wheel hub processing fixture. By arranging a fixing piece that can extend outward, the device can support the inside of the wheel hub to prevent deformation during high-frequency operation. By arranging a clamping block and a guide rod, the clamping block can be tilted according to the curvature of the wheel hub when clamping wheel hubs of different curvatures, so that the clamping block fits the wheel hub, thereby improving the adaptability of the fixture.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a forged wheel hub processing fixture, comprising an operating table, a plurality of sliding grooves uniformly arranged along the circumferential direction on the end surface of the operating table, a sliding sleeve slidingly arranged above the sliding grooves, a plurality of fixing members that can extend outwards are arranged on one side of the sliding sleeve above the plurality of sliding grooves, a connecting block is arranged on one side of the fixing member, a plurality of rollers are arranged on the surface of the connecting block, a mounting block is arranged on one side of the roller on the end surface of the operating table, a plurality of guide rods are arranged inside the mounting block, a return spring is arranged on the outside of the guide rods in connection with the mounting block, and a clamping block is rotatably arranged at one end of the guide rod. The rollers are arranged so as to roll when in contact with the inner wall of the wheel hub to prevent damage to the inner wall of the wheel hub, and after the end surface of the wheel hub is impacted, the support of the rollers can reduce the impact force and reduce the vibration of the wheel hub.

[0007] Preferably, a drive motor is disposed at the bottom of the operating table, and a threaded rod is disposed on the output shaft of the drive motor. The threaded rod is drivingly connected to the sliding sleeve. A drive rod is disposed on the outer circumference of the sliding sleeve, and one end of the drive rod is rotatably connected to the upper end surface of the fixed member. The arrangement of the sliding sleeve allows multiple drive rods to move downward simultaneously, pushing the fixed member to move, so that the fixed member supports the inner wall of the wheel hub.

[0008] Preferably, a fixed connection piece is provided inside the slide groove, and a plurality of driven rods are rotatably provided on the outer circumferential surface of the fixed connection piece, and the driven rods are rotatably connected to the lower side of the end surface of the fixed piece.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Example 1:

[0023] refer to Figure 1 , Figure 2 and Figure 3A forged wheel hub processing fixture includes an operating table 1, a slide groove 2 is provided on the end surface of the operating table 1, a sliding sleeve 3 is slidably provided above the slide groove 2, a plurality of fixing parts 4 that can be extended outward are provided on one side of the sliding sleeve 3, a connecting block 5 is provided on one side of the fixing part 4, a plurality of rollers 6 are provided on the surface of the connecting block 5, a mounting block 7 is provided on one side of the roller 6 on the end surface of the operating table 1, a plurality of guide rods 8 are provided inside the mounting block 7, a return spring 9 is provided outside the guide rod 8, and a clamping block 10 is rotatably provided at one end of the guide rod 8.

[0024] In this solution, there are three fixing parts, which are rotatably connected to the circumferential direction of the sliding sleeve 3. The number of connecting blocks 5 is equal to the number of fixing parts 4. The connecting block 5 is fixedly connected to one side of the fixing part 4. The setting of the roller 6 can roll when it contacts the inner wall of the wheel hub to prevent damage to the inner wall of the wheel hub. After the end face of the wheel hub is impacted, the roller 6 abuts against the inner wall of the wheel hub for support. The anti-slip sleeve 19 made of rubber material gives the roller 6 a certain shock-absorbing effect, reducing the vibration of the wheel hub. Two protrusions are provided on the end face of the clamping block 10, which can make the two ends of the clamping block 10 contact the outer cylindrical surface of the wheel hub first, and then can be adaptively rotated according to the specific shape of the wheel hub, so that the fitting effect of the clamping block 10 and the outer cylindrical surface of the wheel hub is improved.

[0025] refer to Figure 2 , Figure 3 and Figure 4 A driving motor 11 is provided at the bottom of the slide 2, and a threaded rod 12 is provided on the output shaft of the driving motor 11. The threaded rod 12 is transmission-connected to the sliding sleeve 3. A driving rod 13 is provided on the outer circular surface of the sliding sleeve 3, and the driving rod 13 is rotationally connected to the fixing member 4.

[0026] In this solution, a plurality of rotating connecting parts are provided on the outer circumferential surface of the sliding sleeve 3. The rotating connecting parts are prior art and will not be elaborated in this article. The main function is to make the sliding sleeve 3 rotatably connected with the drive rod 13, so that the sliding sleeve 3 drives the plurality of drive rods 13 to move downward and push the fixing part 4 to support the inner wall of the wheel hub.

[0027] refer to Figure 3 A fixed connecting member 14 is provided inside the chute 2, and a plurality of driven rods 15 are rotatably provided on the outer surface of the fixed connecting member 14, and the driven rods 15 are rotatably connected to the fixed member 4.

[0028] In this solution, the fixed connector 14 is fixedly connected to the center position of the slide groove 2, and a bearing is provided inside the fixed connector 14. The bearing is sleeved on the surface of the threaded rod 12. The bearing is a prior art and will not be elaborated in this article. Its main function is to enable the threaded rod 12 to rotate independently and to limit the threaded rod 12 to prevent the position of the threaded rod 12 from shifting.

[0029] refer to Figure 2 , Figure 3 and Figure 5 A cylinder 16 is provided on one side of the mounting block 7, and the output end of the cylinder 16 is rotatably connected to the clamping block 10. A mounting groove 17 is provided inside the mounting block 7, and the guide rod 8 is slidably connected to the inside of the mounting groove 17. One end of the return spring 9 abuts against the inside of the mounting groove 17, and the other end of the return spring 9 is fixedly connected to the guide rod 8.

[0030] In this solution, the output end of the cylinder 16 drives the clamping block 10 to move toward the wheel hub. When the protrusions at both ends of the clamping block 10 contact the outer cylindrical surface of the wheel hub, they will rotate around one end of the output shaft of the cylinder 16, so that the angle of the clamping block 10 tilts with the wheel hub. The two guide rods 8 on one side of the clamping block 10 squeeze the return spring 9 to different degrees due to the change in angle. After being squeezed, the return spring 9 stretches and can push the guide rod 8, so that the guide rod 8 pushes the two ends of the clamping block 10, so that there can be a certain elastic supporting force on both sides of the clamping block 10 that has produced rotational deformation, which facilitates the rotation of the clamping block 10 and improves the stability of clamping the wheel hub.

[0031] refer to Figure 1 The surface of the operating table 1 is provided with a plurality of limit members 18. The limit members 18 can perform preliminary positioning of the wheel hub to improve the accuracy of the milling work.

[0032] In this solution, the limiting member 18 is a plurality of flat cylindrical protrusions, which are smaller than the inner diameter of the hub. The hub is positioned before clamping to prevent friction due to excessive position deviation of the hub.

[0033] refer to Figure 3 and Figure 4 The surface of the roller 6 is provided with an anti-skid cover 19. The anti-skid cover 19 is made of rubber, which can provide a certain shock absorption effect for the roller 6, and can increase the friction between the roller 6 and the inner wall of the hub, thereby improving the stability of the internal support.

[0034] During use, the staff places the wheel hub on the outside of the limit piece 18 for preliminary positioning, and then starts the drive motor 11. When the output shaft of the drive motor 11 drives the threaded rod 12 to rotate, it will drive the sliding sleeve 3 on the surface to move downward, and the sliding sleeve 3 will drive the drive rod 13 on the outer circular surface to move downward. As the distance between the sliding sleeve 3 and the fixed connection piece 14 at the bottom is shortened, the three drive rods 13 will push the fixing piece 4 to move outward along the slide groove 2, so that the roller 6 on one side of the fixing piece 4 fits against the inner wall of the wheel hub, supporting and fixing the inner wall of the wheel hub.

[0035] Then the cylinder 16 is started, and the output end of the cylinder 16 pushes the clamping block 10 to move toward the wheel hub. The protrusions at both ends of the clamping block 10 will first contact the outer cylindrical surface of the wheel hub and tilt along with the outer cylindrical surface. When tilting, the two guide rods 8 squeeze the return spring 9 to different degrees because the angle of the clamping block 10 changes. After being squeezed, the return spring 9 stretches and can push the guide rod 8, so that the guide rod 8 pushes the two ends of the clamping block 10, which is convenient for clamping the wheel hub.

[0036] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0037] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.
