Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheel hub processing technology, and in particular to an adjustable aluminum alloy wheel hub machining clamping device. Background Technology
[0002] Car wheel hubs are one of the most important automotive parts. They are cylindrical metal components that support the tire and are mounted on an axle. The wheel hub production process generally involves forming, drilling, and shaping. In order to ensure production quality, the wheel hub is usually clamped during the processing, so a clamping device is required.
[0003] A search revealed that patent CN212499666U discloses an aluminum alloy wheel hub processing equipment component. The main feature is a drive structure that moves two clamping seats relative to each other, causing the arc-shaped grooves on the two pressure plates to abut against the opposite sides of the circumference of the aluminum alloy wheel hub placed on the positioning plate, thus clamping the wheel hub and ensuring its stable placement on the positioning plate. This allows the wheel hub to have better positioning accuracy, thereby improving the marking position precision. A drive element is also included to move the lifting plate vertically to adjust the marking position.
[0004] This patent utilizes a movable clamping seat and uses arc-shaped grooves on two pressure plates to press against the surface of the wheel hub, achieving a certain clamping effect. However, it still has some drawbacks. For example, when processing larger wheel hubs, if the size of the arc-shaped groove is smaller than the size of the wheel hub, the inner wall of the arc-shaped groove cannot fit tightly against the circumference of the wheel hub. Instead, the two end faces of the arc-shaped groove press against the circumference of the wheel hub, which not only affects the clamping effect but also easily causes wear on the circumference of the wheel hub. It is also difficult to adjust and therefore not suitable for wheel hubs of different sizes, leaving room for improvement. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable aluminum alloy wheel hub machining clamping device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] Preferably, the rear end of the bidirectional screw is rotatably connected to the inner wall of the moving groove, and the two sliders are respectively threaded to the positive and negative threads on the surface of the bidirectional screw. After the handwheel drives the bidirectional screw to rotate, it can drive the two sliders to move towards the opposite surface.

[0013] Preferably, the position of the limiting rod corresponds to the position of the limiting plate, and the limiting rod is adapted to the limiting hole. The limiting rod can be driven by the hydraulic push rod to move into the bottom frame and insert into the limiting hole on the side of the limiting plate, thereby locking the connecting shaft.
[0014] The beneficial effects of this utility model are as follows:
[0015] By setting up movable blocks, lateral compression pads, sliders, clamping plates, and forward compression pads, the positive and negative threaded rods and bidirectional screws can be used to drive them closer to the wheel hub, thereby clamping and pressing the front and rear surfaces and left and right sides of the wheel hub. This changes the traditional arc-shaped clamping method, can be applied to wheel hubs of different sizes, and is flexible and adjustable, making it more practical.
[0016] By setting up a second motor, connecting shaft, limiting plate, and limiting rod, the positioning plate can drive the positioned wheel hub to rotate, thereby performing machining operations on the wheel hub at different angles. Furthermore, by inserting the limiting rod into the limiting hole on the side of the limiting plate, the limiting plate can be locked, thus ensuring that the connecting shaft will not deflect during the wheel hub machining process, resulting in higher stability.

The clamping component 6 includes a first motor 601, and a positive and negative threaded rod 602 fixedly connected to the output end of the first motor 601. Two sliding grooves are opened on the upper surface of the strip frame 3, and movable blocks 603 are slidably connected to the inner bottom walls of the two sliding grooves. The left end of the positive and negative threaded rod 602 is rotatably connected to the inner wall of the sliding groove, and the two movable blocks 603 are respectively threaded to the positive and negative threads on the surface of the positive and negative threaded rod 602.
[0024] Positioning frames 604 are fixedly connected to the opposite faces of the two movable blocks 603. Lateral compression pads 605 are fixedly connected to the opposite faces of the two positioning frames 604. The positions of the two lateral compression pads 605 correspond to the positions of the guide posts 5. Two moving slots are opened on the opposite faces of the two positioning frames 604. The moving slots of every two identical positioning frames 604 form a group. A slider 606 is slidably connected to the inner wall of each group of moving slots. A clamping plate 607 is fixedly connected to the side of the slider 606 away from the inner wall of the moving slot. A forward compression pad 608 is fixedly connected to the opposite face of each group of clamping plates 607. A bidirectional screw 609 is rotatably connected to the front of the two positioning frames 604. The rear end of the bidirectional screw 609 is rotatably connected to the inner wall of the moving slot. The two sliders 606 are threaded to the forward and reverse threads on the surface of the bidirectional screw 609, respectively. A handwheel 610 is fixedly connected to the front end of the two bidirectional screws 609.
[0025] The first motor 601 can drive two movable blocks 603 to move towards the opposite face via the forward and reverse threaded screws 602, thereby driving the lateral compression pads 605 to press against the left and right sides of the wheel hub. At the same time, turning the handwheel 610 can drive two sliders 606 to move towards the opposite face via the bidirectional screw 609, thereby causing the forward compression pads 608 on the opposite face of the two clamping plates 607 to press against the front and rear surfaces of the wheel hub. With the adjustable clamping structure, it can be used for wheel hubs of different sizes, and has high flexibility.
[0026] Example 2: Refer to Figure 1 and Figure 4 The rotating component 2 includes a positioning disk 201. A second motor 202 is fixedly connected to the inner bottom wall of the bottom frame 1. A connecting shaft 203 is fixedly connected to the output end of the second motor 202. The top end of the connecting shaft 203 extends to the upper surface of the bottom frame 1 and is fixedly connected to the lower surface of the positioning disk 201. A limiting disk 204 is fixedly connected to the surface of the connecting shaft 203. Several limiting circular holes 205 are opened on the side of the limiting disk 204.
[0027] A hydraulic push rod 206 is fixedly connected to the right side of the bottom frame 1. The output end of the hydraulic push rod 206 extends into the interior of the bottom frame 1 and is fixedly connected to a limiting round rod 207. The position of the limiting round rod 207 corresponds to the position of the limiting plate 204, and the limiting round rod 207 is adapted to the limiting round hole 205.
[0028] The second motor 202 can drive the positioning disk 201 to rotate via the connecting shaft 203, thereby driving the clamping assembly 6 above to rotate, rotating the positioned wheel hub, thus facilitating the processing of the wheel hub at different angles. After the angle is rotated, the hydraulic push rod 206 drives the limiting round rod 207 to insert into the limiting round hole 205 on the surface of the limiting disk 204, thereby locking the connecting shaft 203 and ensuring the stability of the wheel hub during processing, preventing any deflection.
[0029] Working principle: First, place the wheel hub on the positioning platform 4 and insert the center hole into the surface of the guide post 5. At this time, turn on the first motor 601. The first motor 601 drives the positive and negative threaded rods 602 to rotate, thereby driving the movable blocks 603 in the two sliding grooves to move towards the opposite face until the two lateral extrusion pads 605 press against the two sides of the wheel hub. At this time, the operator manually rotates the two handwheels 610, which drive the bidirectional screw 609 to rotate, thereby driving the sliders 606 in each set of moving grooves to move towards the opposite face, so that the two clamping plates 607 drive the two positive extrusion pads to move towards the opposite face. The pressure pad 608 presses the front and rear surfaces of the wheel hub together, changing the traditional arc-shaped clamping method. It can be used for wheel hubs of different sizes and has high adjustability. The second motor 202 drives the connecting shaft 203 to rotate, which in turn drives the positioned wheel hub to rotate through the positioning plate 201 to change different angles, thereby facilitating the processing of the wheel hub. After rotation, the hydraulic push rod 206 drives the limiting round rod 207 to insert into the limiting round hole 205 on the surface of the limiting plate 204, thereby locking the connecting shaft 203 and ensuring the stability of the wheel hub during the processing.
