Description

Technical Field

[0001] This utility model relates to the technical field of motorcycle wheel hub processing equipment, and in particular to a wheel hub fixing device for motorcycle wheel hub processing. Background Technology

[0002] As a core component connecting the tire and axle, the machining quality of the motorcycle wheel hub directly affects the motorcycle's driving stability and safety. The wheel hub machining process involves multiple steps, including internal bore turning, flange milling, and spoke hole drilling. Precise and stable fixing is a prerequisite for ensuring the machining accuracy of each step. With the increasing demand for lightweight and customized wheels in the motorcycle industry, wheel hub materials are gradually shifting towards lightweight materials such as aluminum alloys and magnesium alloys, and the structures are also exhibiting diverse specifications and irregular shapes. This places higher demands on the fixing devices used in machining.

[0003] However, in existing technologies, most motorcycle wheel hub fixing devices are designed with a fixed angle, which can only fix the wheel hub in a single posture. When machining different parts of the wheel hub (such as the inner spoke groove and the outer flange surface), it is necessary to manually disassemble, flip and re-fix the wheel hub multiple times. This not only increases the labor intensity of the operators, but also causes cumulative errors due to multiple positioning, resulting in a decrease in machining accuracy. Some devices with angle adjustment functions use manual lead screw adjustment, which is cumbersome, time-consuming and cannot achieve precise angle control, making it difficult to meet the angle positioning requirements of high-precision machining.

[0007] Preferably, the lower end of the concave seat is fixed to the upper end of the two sets of support legs, and the extended ends of the two sets of telescopic cylinders are respectively fixed to one end of the two sets of connecting parts.

[0008] Preferably, one end of each of the two sets of triangular members is fixed to one end of the square frame, and both sets of telescopic cylinders and two sets of angle sensors are connected to the control panel for signal transmission.

[0011] Preferably, a guide slide assembly is installed at one end of the square frame, and all three sets of pressure sensors are connected to the control panel for signal transmission.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1.

[0014] 2. This utility model features high fixing reliability: It adopts a three-point fixing structure (two sets of first fixing rods and one set of second fixing rods), combined with real-time monitoring by a pressure sensor, which ensures uniform and controllable clamping force. This avoids wheel hub deformation due to excessive tightness or displacement during processing due to excessive looseness. At the same time, the adjustment of the slide cylinder can adapt to the fixing needs of motorcycle wheel hubs of different specifications and sizes, improving the versatility of the device and reducing the time and cost of changing tooling. Furthermore, the design of the protective sleeve effectively avoids direct contact between the fixing rod and the wheel hub surface, preventing indentations or scratches on the wheel hub surface and ensuring the appearance quality of the wheel hub.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a wheel hub fixing device for motorcycle wheel hub processing, including two sets of support legs 1. A control panel 11 is installed at the front end of one set of support legs 1. An angle adjustment mechanism 2 is provided at the upper end of the two sets of support legs 1. A fixing mechanism 3 is provided at one end of the angle adjustment mechanism 2. The fixing mechanism 3 includes a square frame 31.

[0024] The angle adjustment mechanism 2 includes a concave seat 21. Two sets of triangular members 22 are rotatably mounted inside the concave seat 21 near its end. Two sets of adjusting members 23 are rotatably mounted inside the concave seat 21. A telescopic cylinder 24 is fixedly mounted at one end of each adjusting member 23. Angle sensors 25 are mounted on the inner walls of both sets of triangular members 22. Connecting members 26 are rotatably mounted inside both sets of triangular members 22. The lower end of the concave seat 21 is fixed to the upper end of both sets of support legs 1. The extended ends of the two sets of telescopic cylinders 24 are fixed to one end of each set of connecting members 26. One end of each set of triangular members 22 is fixed to one end of the square frame 31. The two sets of telescopic cylinders 24 and the two sets of angle sensors 25 are all signal connected to the control panel 11.

[0025] The specific settings and functions of this embodiment are described below. The two sets of support legs 1 serve as the load-bearing foundation of the entire device, ensuring the structural stability during the processing. One set of support legs 1 has a control panel 11 installed at its front end, which serves as the operation and control center of the device and integrates functions such as parameter setting, status display and motion control.

[0026] The concave base 21 serves as the mounting base for angle adjustment. Its lower end is fixedly connected to the upper end of the two sets of support legs 1. The two sets of triangular members 22 are rotatably installed inside the concave base 21 near the end position and are the actuators for angle adjustment. The two sets of adjusting members 23 are rotatably installed inside the concave base 21 and are used to install the drive components. The telescopic cylinder 24 is fixedly installed at one end of the adjusting member 23 and provides power for angle adjustment. The angle sensor 25 is installed on the inner wall of the two sets of triangular members 22 and is used to monitor the adjustment angle in real time. The connecting member 26 is rotatably installed inside the two sets of triangular members 22 and is fixedly connected to the extended ends of the two sets of telescopic cylinders 24 respectively.

[0027] Working relationship of angle adjustment mechanism 2: One end of the two sets of triangular parts 22 is fixedly connected to the square frame 31 of the fixed mechanism 3. Through the telescopic movement of the telescopic cylinder 24, the connecting part 26 and the triangular parts 22 are driven to rotate around the rotation axis to realize the angle adjustment of the fixed mechanism 3. The two sets of telescopic cylinders 24 and the two sets of angle sensors 25 are all connected to the control panel 11 to form a closed loop control.

[0028] Example 2: Figure 1 , Figure 2 and Figure 4As shown, the fixing mechanism 3 includes a square frame 31. Two sets of first fixing rods 32 are fixedly installed at one end of the square frame 31. A slide cylinder 33 is fixedly installed at the upper end of the square frame 31. A second fixing rod 34 is fixedly installed at the movable end of the slide cylinder 33. Pressure sensors 35 are installed on the outer walls of the two sets of first fixing rods 32 and second fixing rods 34. Protective sleeves 36 are fitted on the outer sides of the two sets of first fixing rods 32 and second fixing rods 34. The outer walls of the three sets of pressure sensors 35 are in contact with the inner walls of the three sets of protective sleeves 36. The slide cylinder 33 is connected to the control panel 11 via signal. A guide slide assembly 37 is installed at one end of the square frame 31. All three sets of pressure sensors 35 are connected to the control panel 11 via signal.

[0029] The overall effect of this embodiment is as follows: the square frame 31 serves as the mounting base for the fixing mechanism 3 and is fixedly connected to the triangular piece 22; two sets of first fixing rods 32 are fixedly installed at one end of the square frame 31 to form a lower fixed fulcrum; the slide cylinder 33 is fixedly installed at the upper end of the square frame 31 to provide clamping power; the second fixing rod 34 is installed at the movable end of the slide cylinder 33 to form an upper adjustable fixed fulcrum; pressure sensors 35 are respectively installed on the outer walls of the two sets of first fixing rods 32 and second fixing rods 34 to monitor the clamping force; the protective sleeve 36 is fitted on the outside of the two sets of first fixing rods 32 and second fixing rods 34 and contacts the pressure sensor 35; and the guide slide assembly 37 is installed at one end of the square frame 31 to assist in the positioning and installation of the wheel hub.

[0030] The working relationship of the fixing mechanism 3: The slide cylinder 33 is connected to the control panel 11 by signal. By controlling the extension and retraction of the slide cylinder 33, the second fixing rod 34 is moved, which, together with the two sets of first fixing rods 32, realizes the clamping and loosening of the wheel hub. All three sets of pressure sensors 35 are connected to the control panel 11 by signal, providing real-time feedback on the clamping pressure.

[0031] The usage and working principle of this device are as follows: First, the control panel 11 performs a system self-test to check whether each sensor (angle sensor 25, pressure sensor 35) and actuator (telescopic cylinder 24, slide cylinder 33) is working properly. In the initial state, the angle adjustment mechanism 2 is in the horizontal zero position, the slide cylinder 33 of the fixing mechanism 3 is in the retracted state, and the second fixing rod 34 maintains the maximum distance between the two sets of first fixing rods 32, which is convenient for the operator to place the wheel hub.

[0032] Then, the wheel hub is placed: the operator places the motorcycle wheel hub to be processed on the two sets of first fixing rods 32 of the fixing mechanism 3. The guide sliding component 37 plays an auxiliary positioning role to ensure that the wheel hub is initially placed in the correct position.

[0033] Automatic clamping: The control panel 11 issues a clamping command. After receiving the signal, the slide cylinder 33 extends and drives the second fixing rod 34 to move downward. As the second fixing rod 34 gradually approaches the wheel hub, the three sets of protective sleeves 36 (which are respectively fitted on the two sets of first fixing rods 32 and second fixing rods 34) first contact the surface of the wheel hub.

[0034] Pressure feedback and adjustment: When the protective sleeve 36 contacts the wheel hub, the pressure sensor 35 detects the contact pressure in real time and transmits the data to the control panel 11. When the pressure reaches the preset threshold (set according to the wheel hub material and specifications), the control panel 11 sends a signal to stop the slide cylinder 33 from moving, completing the clamping process. If the pressure exceeds the safe range, the system will automatically control the slide cylinder 33 to retract appropriately to prevent the wheel hub from being deformed by pressure.

[0035] Finally, angle setting: The operator inputs the required machining angle parameters through the control panel 11 according to the machining requirements;

[0036] Angle adjustment execution: The control panel 11 sends the angle command to the two sets of telescopic cylinders 24. The telescopic cylinders 24 perform synchronous telescopic actions according to the command. The extended end of the telescopic cylinder 24 drives the triangular piece 22 to rotate around its rotation axis with the concave seat 21 through the connector 26, thereby enabling the square frame 31 (and the wheel hub fixed on it) which is fixedly connected to the triangular piece 22 to achieve angle adjustment.

[0037] Angle closed-loop control: During the angle adjustment process, the angle sensor 25 on the inner wall of the triangular component 22 detects the current angle in real time and feeds it back to the control panel 11. When the actual angle is consistent with the set angle, the control panel 11 sends a signal to stop the telescopic cylinder 24 from moving, so as to ensure the angle adjustment accuracy.

[0038] After fixing and angle adjustment, the device remains in its current state so that the processing equipment can perform the corresponding processing steps on the wheel hub. During the processing, each sensor continuously monitors the pressure and angle status. If any abnormality occurs (such as vibration causing pressure fluctuations to exceed the allowable range, angle deviation, etc.), the control panel 11 will immediately issue an alarm signal. If necessary, the processing equipment can be linked to stop working to prevent the generation of processing waste.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
