Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy wheel rim processing technology, and specifically to a clamping device for aluminum alloy wheel rim processing. Background Technology

[0002] Aluminum alloy wheels are automotive wheels made of aluminum alloy materials. They are lightweight, high-strength, have good heat dissipation, and are corrosion-resistant. Compared with traditional steel wheels, they can improve vehicle performance, fuel efficiency, and handling. They also come in a variety of designs and are commonly used in passenger cars, motorcycles, and high-performance vehicles.

[0003] The machining process of aluminum alloy wheels involves drilling and milling. The typical operation involves using a clamping device on a drilling or milling machine to hold the wheel, followed by drilling, tapping, or milling. Most clamping devices use a chuck to move the jaws, but the contact area between the jaws and the wheel is relatively small, easily damaging the wheel. Furthermore, because the diameters of the aluminum alloy wheels being machined vary, larger diameters require a longer jaw movement path, increasing clamping time, reducing machining speed, and lowering efficiency. Additionally, the jaws are typically made of steel, which can damage the cutting tool when it comes into contact with them during machining, increasing costs and reducing economic viability.

[0004] Therefore, in order to solve the above problems, a clamping device for machining aluminum alloy wheel rims is proposed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a clamping device for machining aluminum alloy wheel rims. This invention enables rapid clamping of aluminum alloy wheel rims of various diameters, improving machining efficiency and avoiding damage to cutting tools during machining, thus improving machining economy.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A clamping device for machining aluminum alloy wheel rims includes a chuck seat, a flange base plate at the bottom of the chuck seat, the flange base plate being mounted on a worktable, a movable block at the output end of the chuck seat being movable along the radial direction of the chuck seat, a mounting component being detachably mounted on the movable block, and the relative position between the mounting component and the movable block being adjustable, a clamping plate being mounted on the mounting component, an upper connecting hole for connecting with the mounting component and a through hole for facilitating connection between the mounting component and the movable block being provided through the clamping plate, and an arc-shaped stepped section being provided on the clamping plate, the cross-sectional shape of which is a stepped cone shape descending from the middle to both sides.

[0008] Preferably, the length direction of the movable block is parallel to its moving direction, and locking strips for sliding engagement with the chuck seat are provided on both sides of the movable block along the length direction of the movable block. A T-slot is opened on the movable block, the length direction of the T-slot is parallel to the length direction of the movable block, the opening of the T-slot faces upward, and a lower friction texture is provided on the side of the movable block outside the opening of the T-slot, the length direction of the lower friction texture is perpendicular to the length direction of the T-slot.

[0009] Preferably, the mounting assembly includes a T-block and a mounting block. The T-block is disposed in a T-slot and can slide along the length of the T-slot. The side of the T-block away from the T-slot is connected to the mounting block via a lower connector. A pad is provided on the side of the mounting block near the T-block. The length of the pad is parallel to the length of the T-slot. An upper friction texture is provided on the side of the pad away from the mounting block. The upper friction texture corresponds to the lower friction texture and can interlock with it.

[0010] Preferably, a lower connecting hole is formed through the mounting block, and a lower threaded hole is formed on the side of the T-block away from the T-slot. The lower connecting hole and the lower threaded hole can be connected by a lower connector. Two lower threaded holes are provided on the T-block, and more than two lower connecting holes are provided on the mounting block. The axes of the lower connecting holes are all parallel to each other and located in the same plane. The axes of the lower threaded holes are parallel to each other, and the plane where the axes of the lower connecting holes are located is the same plane as the plane where the axes of the lower connecting holes are located. The distance between adjacent lower connecting holes is the same as the distance between two lower threaded holes, which facilitates the connection between the lower connecting holes and the lower threaded holes and allows the T-block to be positioned on the mounting block.

[0011] Preferably, the mounting block has several upper threaded holes on the side away from the T-block. The position of the upper threaded holes corresponds to the position of the upper connecting holes on the clamping plate. The upper threaded holes and the upper connecting holes are connected by an upper connector. The number and position of the through holes on the clamping plate correspond to the number and position of the lower connecting holes on the mounting block, and the diameter of the through holes is larger than the diameter of the lower connecting holes.

[0012] Preferably, both the upper and lower connectors are screws, and both the upper and lower connecting holes are countersunk holes.

[0013] Preferably, the clamping plates are made of aluminum alloy and are fan-shaped. Multiple clamping plates are evenly arranged around the chuck seat in a circumferential direction, and the clamping plates can move simultaneously. When clamping, the axis of the arc-shaped stepped section on the clamping plate coincides with the axis of the chuck seat.

[0014] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages:

[0015] This utility model increases the contact area between the clamping device and the aluminum alloy wheel rim by setting a clamping plate on the traditional chuck seat to replace the clamping jaws, thereby avoiding possible damage to the aluminum alloy wheel rim during clamping and improving the processing quality.

[0016] By setting arc-shaped stepped sections on the clamping plate, each step of the stepped section corresponds to an aluminum alloy wheel of a certain diameter, the aluminum alloy wheel can be clamped by moving only a small distance so that it can be fully placed on the step corresponding to its diameter, and then clamped. This eliminates the need for the clamping plate to move too far before clamping, thus improving the clamping speed and thus improving the processing efficiency.

[0017] By setting the cross-sectional shape of the stepped section to a stepped cone shape that descends from the middle to both sides, the three-dimensional space on the clamping plate can be utilized to the maximum extent, while reducing the overall weight of the clamping plate and making it easier to handle and move. The step on the inner side of the stepped cone is used to clamp the outer wall of the aluminum alloy wheel rim, while the step on the outer side of the stepped cone is used to clamp the inner wall of the aluminum alloy wheel rim. That is, the clamping principle of the steps on both sides of the stepped cone is different for the aluminum alloy wheel rim, so that both small-diameter and large-diameter aluminum alloy wheel rims can be quickly clamped in the same set of clamping plates, improving the economy of processing.

[0018] By setting up installation components, and ensuring that the installation components, clamps, and movable blocks are all detachably connected, it is possible to replace different clamps and adjust the relative position between the clamps and the movable blocks, thus avoiding problems such as the center of gravity of the replaced clamps deviating, and improving the safety and practicality of the device.

[0027] 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.

[0028] like Figures 1-6 As shown, this utility model provides a technical solution:

[0029] A clamping device for machining aluminum alloy wheel rims includes a chuck seat 1. The chuck seat 1 is a vertical chuck seat, and can be a commonly available chuck model, preferably a three-jaw chuck. The chuck seat 1 refers to the remaining parts of the chuck after removing the jaws, and its output end is the end of the chuck used to drive the jaws to move. A flange base plate 2 is provided at the bottom of the chuck seat 1, and the flange base plate 2 can be placed on the worktable of a drilling and milling machine. A movable block 3 is provided at the output end of the chuck seat 1. The movable block 3 can move in the radial direction of the chuck seat 1. A mounting component 4 is detachably provided on the movable block 3, and the relative position between the mounting component 4 and the movable block 3 can be adjusted in the radial direction of the chuck seat 1. A clamping plate 5 is provided on the mounting component 4. An upper connecting hole 6 for connecting with the mounting component 4 and a through hole 7 for facilitating the connection between the mounting component 4 and the movable block 3 are provided on the clamping plate 5. An arc-shaped stepped section 8 is provided on the clamping plate 5, and the cross-sectional shape of the stepped section 8 is a stepped cone shape that descends from the middle to both sides.

[0030] In an optional embodiment, the clamping plate 5 is made of aluminum alloy, the same material as the aluminum alloy wheel rim. This ensures that even if the tool touches the clamping plate 5 during milling of the aluminum alloy wheel rim, the clamping plate 5 will not damage the tool, resulting in better economic efficiency. Furthermore, the clamping plate 5 is fan-shaped, which increases the contact area with the aluminum alloy wheel rim, avoids clamping marks, and improves clamping stability. Multiple clamping plates 5 are evenly arranged circumferentially around the chuck seat 1, with the number of clamping plates 5 corresponding to the original number of chuck jaws. The clamping plates 5 can move simultaneously. When clamping the aluminum alloy wheel rim, the axis of the arc-shaped stepped section 8 on the clamping plate 5 coincides with the axis of the chuck seat 1, improving stability.

[0031] In an optional embodiment, the length direction of the movable block 3 is parallel to its moving direction. Along the length direction of the movable block 3, locking strips 31 are provided on both sides of the movable block 3 for sliding engagement with the chuck seat 1 to enhance the sliding stability of the movable block 3. A T-slot 32 is formed on the movable block 3, with its length direction parallel to the length direction of the movable block 3. The opening of the T-slot 32 faces upwards, and a lower friction texture 33 is provided on the side of the movable block 3 outside the opening of the T-slot 32. The length direction of the lower friction texture 33 is perpendicular to the length direction of the T-slot 32 to increase friction and improve the stability of the connection.

[0032] In an optional embodiment, the mounting component 4 includes a T-block 41 and a mounting block 42. The T-block 41 is snapped into the T-slot 32 and can slide along the length of the T-slot 32. The side of the T-block 41 away from the T-slot 32 is connected to the mounting block 42 via a lower connector. A pad 421 is provided on the lower side of the mounting block 42 near the T-block 41. The length of the pad 421 is parallel to the length of the T-slot 32. Preferably, two pads 421 are provided, and the distance between the two pads 421 is the same as the width of the T-slot 32. An upper friction texture 422 is provided on the side of the pad 421 away from the mounting block 42. The upper friction texture 422 corresponds to the lower friction texture 33, and the upper friction texture 422 and the lower friction texture 33 can rub against each other to increase the friction force, prevent relative sliding between the mounting block 42 and the movable block 3, and improve the clamping stability.

[0033] In an optional embodiment, a lower connecting hole 423 is provided through the mounting block 42, and a lower threaded hole 411 is provided on the side of the T-block 41 away from the T-slot 32. The lower connecting hole 423 and the lower threaded hole 411 can be connected by a lower connector. Two lower threaded holes 411 are provided on the T-block 41 to avoid the rotation of the mounting block 42 caused by a single threaded hole connection, thereby improving the stability and safety of the connection. Two or more lower connecting holes 423 are provided on the mounting block 42. The axes of the lower connecting holes 423 are all parallel to each other and located in the same plane. The axes of the lower threaded holes 411 are parallel to each other, and when connected, the plane where the axis of the lower threaded hole 411 is located is the same plane as the plane where the axis of the lower connecting hole 423 is located. The distance between adjacent lower connecting holes 423 is the same as the distance between two lower threaded holes 411, which facilitates the interchange connection between the lower connecting holes 423 and the lower threaded holes 411, so as to change the setting position of the T-block 41 on the mounting block 42, thereby improving the stability and safety of clamping.

[0034] In an optional embodiment, the mounting block 42 has several threaded holes 424 on its side away from the T-block 41. The positions of the threaded holes 424 correspond to the positions of the upper connecting holes 6 on the clamping plate 5. The threaded holes 424 and the upper connecting holes 6 can be connected by an upper connector. The number and position of the through holes 7 on the clamping plate 5 correspond to the number and position of the lower connecting holes 423 on the mounting block 42. The diameter of the through holes 7 is larger than the diameter of the lower connecting holes 423, so that the upper connector can pass through the through holes 7 and connect the T-block 41 and the mounting plate. After the T-block 41 is initially positioned, the T-block 41 and the mounting plate are tightened to fix the relative position between the mounting plate and the movable plate, which improves practicality.

[0035] In an optional embodiment, both the upper and lower connectors are configured as screws and can be tightened with a screwdriver. Both the upper connecting hole 6 and the lower connecting hole 423 are countersunk holes, and the inner wall of the countersunk hole is provided with internal threads to strengthen the connection between the upper connecting hole 6 and the upper threaded hole 424 and the lower connecting hole 423 and the lower threaded hole 411, thereby improving the stability of the connection.

[0036] Working principle: First, the clamping plate 5 is connected to the mounting block 42 via the upper connector. Then, based on the size and center of gravity of the clamping plate 5, the connection position of the lower threaded hole 411 on the T-block 41 and the lower connecting hole 423 on the mounting block 42 is selected. The T-block 41 and the mounting block 42 are initially connected via the lower connector. The T-block 41 is then placed in the T-slot 32, and its position within the T-slot 32 can be adjusted. After determining the position of the T-block 41, the lower connector is tightened to secure the T-block 41. With the relative position of the movable block 3 fixed, the upper friction texture 422 and the lower friction texture 33 are interlocked, improving the stability of the connection. Then, the chuck seat 1 is set on the worktable of the drilling and milling machine through the flange base plate 2. The input end of the chuck seat 1 is connected to the power component to control the output end of the chuck seat 1 to drive the movable block 3 to move along the radial direction of the chuck, thereby clamping the aluminum alloy wheel rim. Placing the aluminum alloy wheel rim on the step of the stepped section 8 with its corresponding diameter can achieve rapid clamping, which is more practical and has higher processing efficiency.
