Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of automotive wheel hub processing technology, and more specifically, to a wheel hub fixing device for automotive wheel hub processing. Background Technology

[0002] Wheel hub fixing devices used in automotive wheel hub processing are key equipment in the automotive parts processing field. They are mainly used in wheel hub turning, drilling, grinding and other processing processes. Their core function is to accurately fix the wheel hub through positioning structure and clamping components, ensuring that the wheel hub will not be displaced due to cutting force, vibration and other factors during processing, thereby ensuring the processing dimensional accuracy and surface quality. At present, the fixing method of screw and threaded ring is widely used in small and medium-sized processing enterprises, repair shops and other scenarios due to its simple structure, convenient operation and strong adaptability. Through the axial pressing or radial clamping action of the screw, combined with the auxiliary locking of the threaded ring, the fixing of wheel hubs of different specifications can be achieved.

[0003] However, the above-described implementation still has the following problems. In terms of anti-loosening performance, the existing screw and threaded ring fixing structure mainly relies on the self-locking characteristics of the thread itself and lacks a dedicated anti-loosening design. During the wheel hub machining process, continuous cutting vibration, machining load, and possible reverse rotation requirements can easily lead to an increase in the thread meshing clearance, which in turn causes the screw or threaded ring to loosen. This not only causes wheel hub positioning deviation and affects machining accuracy, but may also pose a safety hazard due to the wheel hub loosening and falling off. In terms of component service life, loosening of the threaded connection will aggravate the wear of the screw and threaded ring. At the same time, metal chips generated during machining can easily enter the loose thread clearance, causing thread jamming and damage, increasing the maintenance cost and failure frequency of the device. In terms of machining stability, the slight wheel hub movement caused by loosening can lead to excessive surface roughness, dimensional tolerance deviation, and even scrap, reducing machining efficiency and finished product qualification rate, making it difficult to meet the usage requirements of high-precision wheel hub machining. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a wheel hub fixing device for automobile wheel hub processing, which solves the technical problem that nuts are easily loosened by external influences in the prior art.

[0005] According to one aspect, at least one embodiment of this disclosure provides a wheel hub fixing device for automobile wheel hub processing, including a support rod, a support platform fixedly installed at the top end of the support rod, a screw fixedly connected to the top end of the support platform, a tire movably sleeved on the outer surface of the screw, the bottom end of the tire movably connected to the top end of the support platform, a positioning ring movably sleeved on the outer surface of the screw, a wing nut movably connected to the top end of the positioning ring, the inner surface of the wing nut threadedly sleeved with the outer surface of the screw, a connecting frame movably sleeved on the top end of the wing nut, a limit ring fixedly installed at the bottom end of the connecting frame, the outer surface of the limit ring movably sleeved with the inner surface of the wing nut, a fixing block fixedly connected inside the connecting frame, a fixing box fixedly installed at the bottom end of the fixing block, a return spring fixedly installed inside the fixing box, a connecting rod fixedly connected to the left end of the return spring, a limit block fixedly connected to the left side of the connecting rod, a limit groove formed inside the screw, and the inner surface of the limit groove movably sleeved with the outer surface of the limit block.

[0006] As a preferred embodiment of this utility model, sliders are fixedly installed on both the front and rear sides of the connecting rod, and the outer surface of the sliders is movably connected to the inner surface of the fixed block.

[0007] In a preferred embodiment of this invention, the outer surface of the connecting rod is movably connected to the inner surface of the fixing block, and the number of limiting blocks is four.

[0008] As a preferred embodiment of this utility model, the outer surface of the fixing box is movably sleeved with the inner surface of the screw, and the outer surface of the connecting rod is movably sleeved with the inner surface of the fixing box.

[0009] As a preferred embodiment of this utility model, a base plate is movably sleeved on the outer surface of the support rod, and a support frame is fixedly installed at the bottom end of the base plate.

[0010] As a preferred embodiment of this utility model, the support frame is internally fixedly connected to a fixed seat, and the outer surface of the fixed seat is smooth.

[0011] As a preferred embodiment of this utility model, a connecting ring is fixedly installed at the bottom end of the support rod, and the outer surface of the connecting ring is movably sleeved with the inner surface of the fixed seat.

[0012] As a preferred embodiment of this utility model, a servo motor is fixedly connected to the top of the base plate, and a rotating shaft is fixedly connected to the other end of the output shaft of the servo motor.

[0013] As a preferred embodiment of this utility model, a right-angle gear is fixedly installed at the bottom end of the rotating shaft, and the outer surface of the rotating shaft is movably connected to the inner surface of the base plate.

[0014] As a preferred embodiment of this utility model, a second right-angle gear is fixedly sleeved on the outer surface of the support rod, and the second right-angle gear meshes with the first right-angle gear.

[0015] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, by setting a return spring, a connecting rod, a limiting block, and a screw, the operator places the tire on the screw and the positioning ring on the screw, ensuring it is in contact with the top of the tire. At this time, a wing nut is placed on the positioning ring to fix the tire. After fixing, the limiting block is aligned with the limiting groove. After alignment, the spring force of the return spring drives the combination of the connecting rod and the limiting block to reset. At this time, the limiting block will be connected to the limiting groove, and the connecting frame and the screw will be in a fixed state. At the same time, the wing nut is also fixed to the screw. This design can effectively prevent the wing nut from loosening, improve the stability of the connection, counteract the loosening tendency caused by cutting force, vibration, or reverse rotation during processing, ensure that the tire remains firmly fixed throughout the entire processing cycle, avoid axial movement or radial displacement, and ensure processing continuity.

[0016] 2. In this disclosure, by setting up a first right-angle gear, a second right-angle gear, a servo motor, and a fixed base, the operator starts the servo motor, whose output shaft drives the rotating shaft to rotate. During the rotation of the rotating shaft, the first right-angle gear and the second right-angle gear meshing with the first right-angle gear will rotate together. When the second right-angle gear rotates, it will drive the support rod to rotate. The support rod ensures the stability during the rotation process through the combination of the connecting ring and the fixed base. The rotation of the support rod will drive the support table to rotate. At this time, the tire fixed on the support table will also rotate. The entire assembly can rotate the fixed tire to any angle as needed. It can align the work station references of different processing steps such as drilling, grinding, and turning without disassembly and reassembly, or fine-tune the relative position of the tire and the tool, avoiding processing misalignment caused by initial clamping deviation and improving the accuracy of process connection.

A limiting groove 15 is opened inside the screw 3. The inner surface of the limiting groove 15 is movably sleeved with the outer surface of the limiting block 14.

[0027] The outer surface of the wing nut 6 is provided with two handles for easy rotation by the operator. When installing the wing nut 6, the fixing box 10 needs to be aligned with the screw 3 for connection. The top of the screw 3 has a groove that fits tightly with the shape of the fixing box 10. During installation, the combination of the connecting rod 12 and the limiting block 14 needs to be retracted into the fixing box 10 before installation can be performed. The top of the connecting rod 12 is fixedly connected to a handle, which the operator can easily move by gripping the handle. The positioning ring 5 has a frustum design, with the small end facing down for easy connection with the wheel hub of the tire 4, and the large end facing up for easy connection and fixation with the wing nut 6.

[0028] In some examples, sliders 13 are fixedly installed on both the front and rear sides of the connecting rod 12, and the outer surface of the sliders 13 is movably connected to the inner surface of the fixing block 9.

[0029] The connecting rod 12 is limited by the slider 13, so that the connecting rod 12 moves along a preset trajectory, ensuring the stability of the movement.

[0030] In some examples, the outer surface of the connecting rod 12 is movably connected to the inner surface of the fixing block 9, and there are four limiting blocks 14.

[0031] The connecting frame 7 is fixed by the limiting block 14. The design of multiple limiting blocks 14 improves the tightness of the connection with the limiting groove 15.

[0032] In some examples, the outer surface of the fixing box 10 is movably sleeved with the inner surface of the screw 3, and the outer surface of the connecting rod 12 is movably sleeved with the inner surface of the fixing box 10.

[0033] During the installation of the wing nut 6, the fixing box 10 will connect with the groove at the top of the limiting groove 15 to complete the subsequent limiting.

[0034] In some examples, the outer surface of the support rod 1 is movably fitted with a base plate 16, and a support frame 17 is fixedly installed at the bottom end of the base plate 16.

[0035] The base plate 16 is supported by the support frame 17, which ensures the stability of the base plate 16 during use. The bottom end of the support frame 17 is in close contact with the ground.

[0036] In some examples, the support frame 17 is internally fixedly connected to a mounting base 18, the outer surface of which is smooth.

[0037] The support rod 1 is limited by the fixed seat 18, so that the support rod 1 rotates according to the preset trajectory and will not be misaligned.

[0038] In some examples, a connecting ring 19 is fixedly installed at the bottom end of the support rod 1, and the outer surface of the connecting ring 19 is movably sleeved with the inner surface of the fixed seat 18.

[0039] The support rod 1 ensures stability during rotation through the connecting ring 19, thereby improving safety during the subsequent processing of the tire 4.

[0040] In some examples, a servo motor 20 is fixedly connected to the top of the base plate 16, and a rotating shaft 21 is fixedly connected to the other end of the output shaft of the servo motor 20.

[0041] When the position of tire 4 needs to be adjusted, the servo motor 20 is started and its output shaft will drive the rotating shaft 21 to rotate.

[0042] In some examples, a right-angle gear 22 is fixedly mounted at the bottom of the shaft 21, and the outer surface of the shaft 21 is movably connected to the inner surface of the base plate 16.

[0043] During the rotation of the shaft 21, it will drive the first right-angle gear 22 to rotate together. The shaft 21 is limited by the base plate 16 to ensure stability during rotation.

[0044] In some examples, a second right-angle gear 23 is fixedly sleeved on the outer surface of the support rod 1, and the second right-angle gear 23 meshes with the first right-angle gear 22.

[0045] During the rotation of the first right-angle gear 22, it will drive the second right-angle gear 23, which meshes with it, to rotate together. The rotation of the second right-angle gear 23 will drive the support rod 1 to rotate.

[0046] Working principle and usage process of this utility model: During use, the operator places the tire 4 onto the screw 3 and supports it with the support platform 2. At this time, the positioning ring 5 is placed on the screw 3 and fits against the top of the tire 4. Then, the wing nut 6 is placed on the positioning ring 5 to fix the tire 4. After fixing, the operator pulls the connecting rod 12 to move the limiting block 14 and compress the return spring 11. At this time, the limiting block 14 will be completely retracted into the fixing box 10. The operator rotates the connecting frame 7 to align the fixing box 10 with the limiting groove 15. After alignment, the elastic force of the return spring 11 drives the combination of the connecting rod 12 and the limiting block 14 to reset. At this time, the limiting block 14 will be connected with the limiting groove 15, and the connecting frame 7 and the screw 3 are in a fixed state. At the same time, the wing nut 6 is also in a fixed state with the screw 3. This design can effectively prevent the wing nut 6 from loosening, improve the stability of the connection, and counteract the loosening tendency caused by cutting force, vibration or reverse rotation during processing.

[0047] After the tire 4 is installed, when the position of the tire 4 needs to be adjusted, the operator starts the servo motor 20. Its output shaft will drive the rotating shaft 21 to rotate. During the rotation of the rotating shaft 21, the first right-angle gear 22 will rotate. When the first right-angle gear 22 rotates, it will drive the second right-angle gear 23 that meshes with it to rotate together. When the second right-angle gear 23 rotates, it will drive the support rod 1 to rotate. The support rod 1 ensures the stability during the rotation through the combination of the connecting ring 19 and the fixed seat 18. The rotation of the support rod 1 will drive the support platform 2 to rotate. At this time, the tire 4 fixed on the support platform 2 will also rotate. The whole thing will rotate the fixed tire 4 to any angle as needed, and it can be aligned with the work station reference of different processing steps such as drilling, grinding and turning without disassembly and reassembly.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
