Description

A hydraulic tooling for wheel hub machining Technical Field

[0001] This utility model relates to the field of wheel hub processing technology, and in particular to a hydraulic tooling for wheel hub processing. Background Technology

[0002] As a key component of vehicles such as automobiles and motorcycles, wheel hubs not only support the weight of the vehicle but also play a decisive role in driving safety, handling stability, and comfort. With the booming development of the automotive industry and the continuous improvement of consumers' requirements for vehicle performance and appearance, the market demand for wheel hubs is growing, which also puts forward higher standards for their processing precision, production efficiency, and surface quality. Traditional wheel hub processing tooling has gradually exposed many problems, prompting the emergence of new hydraulic tooling for wheel hub processing.

[0003] Currently, when machining wheel hubs, most of the time the outer side of the wheel hub is fixed. However, the fixing device will block the outer side of the wheel hub, which greatly reduces the operating space when machining the outer side of the wheel hub, such as turning, milling, and grinding. The range of motion of the cutting tool is limited, making it difficult to operate accurately.

[0004] In response to the technical problem that fixing devices on the outside of the wheel hub would obstruct part of the outer area of ​​the wheel hub, this application proposes a hydraulic tooling for wheel hub processing. Summary of the Invention

[0005] The purpose of this invention is to address the drawback of the fixing device obscuring part of the outer area of ​​the wheel hub when fixing it on the outside. A hydraulic tooling for wheel hub processing is proposed to fix the wheel hub from the inside. Compared to the traditional method of fixing the wheel hub from the outside, this method prevents the fixing device from obstructing the outer side of the wheel hub, thus facilitating processing of the outer side. Furthermore, the turntable can be rotated to bring the side of the wheel hub to be processed closer, making it easier for workers to perform processing operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic tooling for wheel hub processing, comprising a base, with support columns fixedly connected to the four corners of the top of the base, a worktable fixedly connected to the top of the support columns, a turntable rotatably connected to the inner wall of the worktable, a control rod provided on the inner wall of the left end of the worktable, the control rod being connected to a connecting plate via a pressing component, the outer wall of the connecting plate being slidably connected to the inner wall of the worktable, the connecting plate being connected to the turntable via a limiting component, a hydraulic rod fixedly connected to the top of the base, a moving block rotatably connected to the top of the hydraulic rod, and the moving block being connected to a fixed plate via a fixing component.

[0007] Furthermore, the pressing assembly includes a cam fixedly connected to the inner wall of the bottom end of the control rod, the bottom end of the cam being close to the top end of the connecting plate, a connecting shaft fixedly connected to the inner wall of the control rod, and the outer wall of the connecting shaft being rotatably connected to the inner wall of the worktable.

[0008] Furthermore, spring coils are fixedly connected to both sides of the outer wall of the connecting shaft, and one outer end of the spring coil is fixedly connected to the inner wall of the worktable.

[0009] Furthermore, the limiting component includes a second locking tooth fixedly connected to the right end of the connecting plate, the outer wall of the second locking tooth being slidably connected to the inner wall of the worktable, and a first locking tooth fixedly connected to the outer wall of the turntable, the first locking tooth and the second locking tooth engaging with each other.

[0010] Furthermore, a return spring is fixedly connected to the bottom end of the second tooth, and the bottom end of the return spring is fixedly connected to the bottom end of the inner wall of the worktable.

[0011] Furthermore, the limiting component includes connecting rods rotatably connected to the four sides of the inner wall of the moving block, the bottom end of the fixing plate is rotatably connected to the top end of the connecting rods, and the outer wall of the fixing plate is slidably connected to the inner wall of the turntable.

[0012] Furthermore, sliders are fixedly connected to all four sides of the outer wall of the movable block, and grooves are provided on all four sides of the inner wall of the turntable, with the outer wall of the slider slidably connected to the inner wall of the groove.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the moving block is driven to move upward by the hydraulic rod, so that the connecting rod moves the fixing plate to the outside of the turntable, thereby supporting the fixing plate on the inside of the wheel hub, realizing the fixing of the wheel hub from the inside. Compared with the traditional fixing of the wheel hub from the outside, this method does not block the outside of the wheel hub, thus facilitating the processing of the outside of the wheel hub.

[0015] 2. In this utility model, by pulling the control lever forward, the control lever drives the cam to press down the connecting plate, thereby causing the second cleat to move down, canceling the limit on the turntable, and enabling the turntable to rotate, so that the side of the wheel hub that needs to be processed can be rotated to the front, thus facilitating the worker to perform processing and other operations.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Referring to Figures 1-3, one embodiment of this utility model provides a hydraulic tooling for wheel hub processing, including a base 1. Support columns 2 are fixedly connected to the four corners of the top of the base 1. A worktable 3 is fixedly connected to the top of the support columns 2. A turntable 4 is rotatably connected to the inner wall of the worktable 3. A control rod 6 is provided on the inner wall of the left end of the worktable 3. A cam 7 is fixedly connected to the inner wall of the bottom end of the control rod 6. The bottom end of the cam 7 is close to the top of the connecting plate 10. A connecting shaft 8 is fixedly connected to the inner wall of the control rod 6, and the outer wall of the connecting shaft 8 is rotatably connected to the inner wall of the worktable 3. Spring coils 9 are fixedly connected to both sides of the outer wall of the connecting shaft 8. One end of the outer side of the spring coil 9 is fixedly connected to the inner wall of the worktable 3. The outer wall of the connecting plate 10 is slidably connected to the inner wall of the worktable 3. A second locking tooth 11 is fixedly connected to the right end of the connecting plate 10. The outer wall of the second locking tooth 11 is slidably connected to the inner wall of the worktable 3. A first locking tooth 5 is fixedly connected to the outer wall of the turntable 4. The first locking tooth 5 and the second locking tooth 11 engage with each other. A return spring 12 is fixedly connected to the bottom end of the second locking tooth 11. The bottom end of the return spring 12 is fixedly connected to the bottom end of the inner wall of the worktable 3.

[0024] Specifically, after the hub is rotated to the appropriate position, the control lever 6 is released, and the spring coil 9 is no longer restricted, causing the spring coil 9 to drive the connecting shaft 8 to rotate. As a result, the control lever 6 rotates backward to return to its original position, and at the same time, the cam 7 tilts forward. At this time, the return spring 12 pushes the second locking tooth 11 upward, so that the second locking tooth 11 engages with the first locking tooth 5, thereby limiting the turntable 4 and fixing the turntable 4 and the hub in the current position.

[0025] Referring to Figure 4, a hydraulic rod 13 is fixedly connected to the top of the base 1, and a movable block 14 is rotatably connected to the top of the hydraulic rod 13. Connecting rods 17 are rotatably connected to the four sides of the inner wall of the movable block 14. The bottom of the fixed plate 18 is rotatably connected to the top of the connecting rods 17. The outer wall of the fixed plate 18 is slidably connected to the inner wall of the turntable 4. Slider 15 is fixedly connected to the four sides of the outer wall of the movable block 14. Slide grooves 16 are opened on the four sides of the inner wall of the turntable 4. The outer wall of the slider 15 is slidably connected to the inner wall of the slide groove 16.

[0026] Specifically, when in use, the hydraulic rod 13 is connected to an external hydraulic system, allowing hydraulic oil to enter the hydraulic rod 13 through the pipes on the hydraulic rod 13 to control the hydraulic rod 13. When the moving block 14 moves up and down, the sliders 15 on the four sides of its outer wall will slide in the slide groove 16 to ensure the stability of the moving block 14 moving up and down.

[0027] Working principle: In use, place the wheel hub on the turntable 4, then activate the hydraulic rod 13. The hydraulic rod 13 drives the moving block 14 to move upward, which in turn drives the connecting rods 17 on all four sides to move. This causes the side of the connecting rod 17 closest to the moving block 14 to move upward, thereby pushing the fixing plate 18 outward from the turntable 4. The fixing plate 18 then supports the inner side of the wheel hub, fixing the wheel hub in place, thus facilitating the processing of the outer side of the wheel hub. When processing the wheel hub, the control lever 6 can be pulled forward to control the wheel hub. The control rod 6 drives the connecting shaft 8 to rotate, which in turn compresses the spring coil 9. Meanwhile, the bottom end of the control rod 6 causes the cam 7 to press the connecting plate 10 downward. The connecting plate 10 then drives the second locking tooth 11 to slide downward, causing the first locking tooth 11 to disengage from the second locking tooth 5 and compressing the bottom return spring 12. At this point, the turntable 4 is no longer limited, and the moving block 14 can rotate at the drive end of the hydraulic rod 13, allowing the rotating hub to drive the turntable 4 to rotate together, turning the side that needs to be processed to the worker's face for easy processing.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
