Description

Technical Field

[0001] This utility model relates to the field of automotive parts equipment technology, and in particular to a contour positioning fixture for machining wheel hub curved surfaces. Background Technology

[0002] A wheel hub is a cylindrical metal component that supports the tire's inner contour. It is centrally mounted on the axle and is also known as a wheel rim or steel rim. A wheel hub surface machining fixture is a special fixture designed specifically for machining the curved surface of a wheel hub. It is mainly used to fix the wheel hub and ensure its stability during machining, while also adapting to the special requirements of curved surface machining.

[0003] Current wheel hub positioning fixtures mainly move from the center to the center in four or six directions and clamp by compression and limiting. Due to the curved surface characteristics of the wheel hub, they may not be able to effectively fit the wheel hub surface, causing positioning deviation, which leads to unstable workpiece position and affects machining accuracy. Secondly, when it is necessary to process the bottom wheel hub, the staff needs to close the clamp and manually reverse the wheel hub for processing. Although it is not complicated, it is very labor-intensive and time-consuming, thus affecting work efficiency.

[0004] To address the above issues, we have developed a contour positioning fixture for machining wheel hub curved surfaces. Utility Model Content

[0005] This utility model discloses a contour positioning fixture for machining the curved surface of a wheel hub, aiming to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A contour positioning fixture for machining the curved surface of a wheel hub includes a main body, a fixed frame fixedly connected to the main body, a threaded rod rotatably connected inside the fixed frame, one end of the threaded rod contacting the main body, a first motor fixedly connected to the fixed frame, the output end of the first motor connected to the threaded rod, a first guide rod fixedly connected inside the fixed frame, one end of the first guide rod contacting the main body, a first sliding block slidably connected to the first guide rod, and the first sliding block threadedly connected to the threaded rod.

[0007] In a preferred embodiment, rectangular slide rails are symmetrically fixedly connected to the first sliding block, and a first groove is formed in each of the two rectangular slide rails. A second sliding block is slidably connected between the two first grooves. A second groove is formed in the second sliding block, and sliding rods are symmetrically slidably connected in the second grooves. A first connecting rod is fixedly connected to each of the two sliding rods.

[0008] In a preferred embodiment, a rectangular block is fixedly connected to one end of each of the two first connecting rods, and a second optical rod is symmetrically fixedly connected to the first sliding block. The two rectangular blocks are rotatably connected to the two second optical rods. A connecting block is fixedly connected to the side of each of the two rectangular blocks, and an arc-shaped clamp is fixedly connected to one end of each of the two connecting blocks.

[0009] In a preferred embodiment, an L-shaped block is fixedly connected to the first sliding block, a disk is rotatably connected to the bottom of the L-shaped block, a second motor is fixedly connected to the L-shaped block, the output end of the second motor is connected to the disk, a third optical rod is fixedly connected to the bottom of the disk, a circular block is fixedly connected to one end of the third optical rod, a second connecting rod is rotatably connected to the third optical rod, and a fourth optical rod is fixedly connected to the second sliding block, the fourth optical rod being rotatably connected to the second connecting rod.

[0010] In a preferred embodiment, both the first motor and the second motor are electrically connected to an external control device.

[0011] The contour positioning fixture for machining curved surfaces of wheel hubs provided by this utility model has the following advantages: Firstly, when the first connecting rod moves relative to the second groove, the rectangular block swings around the second guide rod due to the movement of the first connecting rod. When the rectangular block swings, the connecting block fixedly connected to it can drive the two arc-shaped clamps to move relative to each other, thereby clamping the middle curved surface of the hub. The arc-shaped clamps can closely fit the middle curved surface of the hub, providing stable support and positioning, effectively improving processing accuracy and efficiency, reducing processing errors, and extending the service life of the equipment.

[0012] Secondly, when the bottom surface of the wheel hub needs to be processed, the operator can drive the first motor to rotate the threaded rod. The threaded rod is connected by a thread, which drives the first sliding block to move arbitrarily to the required position on the first smooth rod, so that the operator can process or observe the surface of the wheel hub, further improving work efficiency.

[0022] In this embodiment, during actual use, the operator can drive the first motor 4 to rotate the threaded rod 3. The threaded rod 3, connected by a thread, can move the first sliding block 6 to any desired position on the first smooth rod 5.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, a rectangular slide rail 7 is symmetrically fixedly connected to the first sliding block 6. A first groove 8 is provided in each of the two rectangular slide rails 7. A second sliding block 9 is slidably connected between the two first grooves 8. A second groove 10 is provided in the second sliding block 9. A sliding rod 11 is symmetrically slidably connected in the second groove 10. A first connecting rod 12 is fixedly connected to each of the two sliding rods 11.

[0024] In this embodiment, by driving the second sliding block 9 to slide within the first groove 8, the first connecting rod 12 on the two sliding rods 11 can be driven to move relative to each other within the second groove 10.

[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, a rectangular block 13 is fixedly connected to one end of each of the two first connecting rods 12, and a second light rod 14 is symmetrically fixedly connected to the first sliding block 6. The two rectangular blocks 13 are rotatably connected to the two second light rods 14. A connecting block 15 is fixedly connected to the side of each of the two rectangular blocks 13, and an arc-shaped clamp 16 is fixedly connected to one end of each of the two connecting blocks 15.

[0026] In this embodiment: when the first connecting rod 12 moves relative to the second groove 10, the rectangular block 13 swings around the second light rod 14 due to the movement of the first connecting rod 12. When the rectangular block 13 swings, the connecting block 15 fixedly connected to it can drive the two arc-shaped clamps 16 to move relative to each other, thereby clamping the middle curved surface of the hub.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, an L-shaped block 17 is fixedly connected to the first sliding block 6, a disk 18 is rotatably connected to the bottom of the L-shaped block 17, a second motor 19 is fixedly connected to the L-shaped block 17, the output end of the second motor 19 is connected to the disk 18, a third optical rod 20 is fixedly connected to the bottom of the disk 18, a circular block 21 is fixedly connected to one end of the third optical rod 20, a second connecting rod 22 is rotatably connected to the third optical rod 20, a fourth optical rod 23 is fixedly connected to the second sliding block 9, and the fourth optical rod 23 is rotatably connected to the second connecting rod 22.

[0028] In this embodiment: the operator drives the second motor 19 to make the disk 18 rotate, thereby driving the third light rod 20 to make an eccentric movement. Through the bidirectional connection of the second connecting rod 22, the fourth light rod 23 drives the second sliding block 9 to slide in the first groove 8.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, both the first motor 4 and the second motor 19 are electrically connected to an external control device.

[0030] In this embodiment, the operator uses an external control device to start the first motor 4 and the second motor 19 to make the equipment run. When the operation is finished, both motors can be turned off at the same time for convenient control.

[0031] Working principle: When in use, the hub is first placed on the main body 1. The operator drives the second motor 19 to make the disc 18 rotate, which in turn drives the third light rod 20 to make an eccentric movement. Through the bidirectional connection of the second connecting rod 22, the fourth light rod 23 drives the second sliding block 9 to slide in the first groove 8, which can drive the first connecting rod 12 on the two sliding rods 11 to make relative movement in the second groove 10. Due to the movement of the first connecting rod 12, the rectangular block 13 swings with the second light rod 14 as the center. When the rectangular block 13 swings, the connecting block 15 fixedly connected to it can drive the two arc-shaped clamps 16 to make relative movement, thereby clamping the middle curved surface of the hub. When the bottom surface of the wheel hub needs to be processed, the operator can drive the first motor 4 to drive the threaded rod 3 to rotate. The threaded rod 3 is connected by a thread, which drives the first sliding block 6 to move arbitrarily to the desired position on the first smooth rod 5 so that the operator can further process or observe the surface of the wheel hub. It should be noted that this application requires the use of a controller or other components with control effects in actual use. Since these are known technologies and not within the scope of protection of this application, they are not shown in this application.
