Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle wheel hub production technology, and more specifically to an automated feeding device for new energy vehicle wheel hub production. Background Technology

[0002] A car wheel hub is a cylindrical metal component in a car tire that supports the tire centered on the axle. Its main function is to bear the rigid rotational inertia between the car and the tire, ensuring that the tire is fixed on the axle so that the vehicle can drive normally. With the growth of the global automotive industry, especially the rise of new energy vehicles, the demand for wheel hubs continues to rise. The traditional design of fuel-powered car wheel hubs can no longer meet the requirements of new energy vehicles for lightweight, high efficiency, and intelligence, prompting wheel hub production technology to accelerate its iteration towards material innovation, structural optimization, and functional integration.

[0003] However, new energy vehicle wheels typically adopt a lightweight design and have a wide size range. The existing feeding devices usually use a fixing structure that directly clamps the wheel surface, which can easily cause bumps and knocks. At the same time, the clamping force of the traditional fixing structure is too large, which can easily cause deformation of the lightweight wheel surface and affect the production quality of the wheel. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides an automated feeding device for the production of wheel hubs for new energy vehicles, so as to solve the problems that the existing fixing structure in the background art is prone to causing bumps and knocks on the surface of the wheel hub, and that excessive clamping force can easily cause the wheel hub to deform.

[0005] This utility model provides the following technical solution: an automated feeding device for the production of wheel hubs for new energy vehicles, including a wheel hub production line and a linear guide rail fixedly installed at one end thereon. A support frame is fixedly installed at the top of the linear guide rail, an L-shaped bracket is provided at one end of the support frame, a crossbar is fixedly connected to one side of the bottom end of the L-shaped bracket, and a flexible clamping component for fixing the wheel hub is provided on the surface of the crossbar. The flexible clamping assembly includes two movable frames sleeved on the surface of the crossbar. A load-bearing frame is fixedly connected to the bottom end of the movable frame. Two extension blocks are fixedly connected to the inner wall of the load-bearing frame. A clamping roller is installed in the middle of the extension block. A silicone gasket is sleeved on the surface of the clamping roller.

[0006] Preferably, the inner cavity of the crossbar is rotatably connected to a bidirectional screw, and the surface of the bidirectional screw has two helical grooves with opposite directions of rotation and equal pitch.

[0007] Preferably, a motor for driving the bidirectional screw is installed at one end of the crossbar, and the output end of the motor passes through one end of the crossbar and is fixedly connected to one end of the bidirectional screw.

[0008] Preferably, a movable groove is provided at the bottom center of the crossbar, and a connecting roller is fixedly connected to the bottom of the inner cavity of the movable frame. The top of the connecting roller passes through the movable groove and is movably connected to the inner cavity of the spiral groove.

[0009] Preferably, the support frame has a sliding groove at one end near the L-shaped bracket, and one end of the L-shaped bracket is movably connected to the inner cavity of the sliding groove.

[0010] Preferably, a cylinder is fixedly installed at the bottom of the inner cavity of the slide groove, and the extended end of the cylinder is fixedly connected to the bottom end of the L-shaped bracket.

[0011] The technical effects and advantages of this utility model are as follows: 1. This utility model uses a flexible clamping assembly to clamp and fix the wheel hub. Four clamping rollers are distributed in a rectangular array on the surface of the wheel hub to clamp and fix it. At the same time, silicone gaskets are added to the surface of the clamping rollers to prevent the clamping rollers from bumping or hitting the surface of the wheel hub. It can also prevent excessive clamping force from causing deformation of the surface of the wheel hub, effectively reducing the risk of bumping or deformation of the wheel hub during the fixing process and ensuring the product quality of the wheel hub.

[0012] 2. This utility model uses a bidirectional screw to adjust the distance between the clamping rollers on both sides. When it is necessary to adjust the distance between the clamping rollers on both sides, the bidirectional screw is driven to rotate by a motor. Since the two spiral grooves on its surface rotate in opposite directions and the pitch of the two spiral grooves is equal, the connecting rollers connected to the inner cavity move with the rotation direction of the spiral grooves when rotating. This causes the two movable frames to move at the same speed on the surface of the crossbar, so that the distance between the two load-bearing frames changes by an equal distance as the bidirectional screw rotates. This allows the device to be used for feeding wheel hubs of different sizes. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automated feeding device for the production of new energy vehicle wheel hubs involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] This utility model provides an automated feeding device for the production of wheel hubs for new energy vehicles, such as... Figure 1 - Figure 4 As shown, the device includes a wheel hub production line 1 and a linear guide rail 2 fixedly installed at one end of the line. A support frame 3 is fixedly installed at the top of the linear guide rail 2, and an L-shaped bracket 4 is provided at one end of the support frame 3. A crossbar 5 is fixedly connected to one side of the bottom end of the L-shaped bracket 4. A flexible clamping component 6 for fixing the wheel hub is provided on the surface of the crossbar 5. The linear guide rail 2 is existing technology and is relatively mature, so it will not be described in detail here. The linear movement of the linear guide rail 2 drives the support frame 3 to move linearly on the side of the wheel hub production line 1 to complete the wheel hub feeding operation. The device can be directly installed on the linear guide rail 2 through the support frame 3, making the disassembly and installation of the feeding device more convenient and easy to install in different positions to meet the flexible needs of multi-model mixed-line production.

[0020] Furthermore, such as Figure 1 and Figure 2As shown, the flexible clamping assembly 6 includes two movable frames 61 sleeved on the surface of the crossbar 5. A load-bearing frame 62 is fixedly connected to the bottom end of each movable frame 61. Two extension blocks 63 are fixedly connected to the inner wall of the load-bearing frame 62. A clamping roller 64 is installed in the middle of each extension block 63. A silicone gasket 65 is sleeved on the surface of the clamping roller 64. In use, the flexible clamping assembly 6 is positioned above the wheel hub production line 1. The completed wheel hubs are placed on the wheel hub production line 1 and clamped and fixed by the flexible clamping assembly 6 before feeding. The two load-bearing frames 62 are located on the wheel hub... On both sides, four clamping rollers 64 are arranged in a rectangular array on the surface of the wheel hub. The surface of the wheel hub is clamped and fixed by the four clamping rollers 64. Since existing new energy wheel hubs usually adopt a lightweight design, the existing fixed structure is prone to causing bumps and knocks on the surface of the wheel hub when clamping and fixing the wheel hub. Therefore, silicone gaskets 65 are added to the surface of the clamping rollers 64 to reduce the risk of bumps and knocks caused by contact between the clamping rollers 64 and the surface of the wheel hub. At the same time, it can also prevent the clamping force of the clamping rollers 64 from being too large, which could cause deformation of the surface of the wheel hub.

[0021] Furthermore, such as Figure 3 As shown, a bidirectional screw 7 is rotatably connected to the inner cavity of the crossbar 5. Two helical grooves 8 are formed on the surface of the bidirectional screw 7. The two helical grooves 8 have opposite directions of rotation and equal pitch.

[0022] Furthermore, such as Figure 1 and Figure 3 As shown, a motor 9 for driving the bidirectional screw 7 to rotate is installed at one end of the crossbar 5. The output end of the motor 9 passes through one end of the crossbar 5 and is fixedly connected to one end of the bidirectional screw 7. The distance between the two load-bearing frames 62 is adjusted by the bidirectional screw 7, so that the flexible clamping assembly 6 can be adapted to wheel hubs of different sizes.

[0023] Furthermore, such as Figure 3 and Figure 4 As shown, a movable groove 10 is provided in the middle of the bottom end of the crossbar 5. A connecting roller 66 is fixedly connected to the bottom end of the inner cavity of the movable frame 61. The top end of the connecting roller 66 passes through the movable groove 10 and is movably connected to the inner cavity of the spiral groove 8. When it is necessary to adjust the distance between the clamping rollers 64 on both sides, the motor 9 is started, and the bidirectional screw 7 is driven to rotate by the motor 9. Since the two spiral grooves 8 on its surface rotate in opposite directions, when rotating, the connecting roller 66 connected to the inner cavity moves with the rotation direction of the spiral groove 8, causing the two movable frames 61 to move on the surface of the crossbar 5 at the same speed and in opposite directions. At the same time, the pitch of the two spiral grooves 8 is equal, and the distance between the two load-bearing frames 62 will change by an equal distance as the bidirectional screw 7 rotates.

[0024] Furthermore, such as Figure 1As shown, a groove 11 is provided at one end of the support frame 3 near the L-shaped bracket 4. One end of the L-shaped bracket 4 is movably connected to the inner cavity of the groove 11. The L-shaped bracket 4 is movably connected to the support frame 3 through the groove 11.

[0025] Furthermore, such as Figure 1 As shown, a cylinder 12 is fixedly installed at the bottom of the inner cavity of the slide 11. The extended end of the cylinder 12 is fixedly connected to the bottom of the L-shaped bracket 4. By extending and retracting the extended end of the cylinder 12, the L-shaped bracket 4 is driven to move up and down in the inner cavity of the slide 11. When picking up material, the extended end of the cylinder 12 is shortened to make the L-shaped bracket 4 descend. After the wheel hub is fixed by the flexible clamping component 6, the extended end of the cylinder 12 is extended to make the L-shaped bracket 4 rise. It is used in conjunction with the linear guide rail 2 to realize the feeding operation of the wheel hub. No manual intervention is required in the whole process, which effectively realizes the automated operation of the device.

[0026] The working principle of this utility model is as follows: First, the finished wheel hub is temporarily placed on the wheel hub production line 1. According to the position of the wheel hub, the linear guide rail 2 drives the flexible clamping assembly 6 to move above the wheel hub. In the initial state, the distance between the two movable frames 61 in the flexible clamping assembly 6 is the largest. Then, the cylinder 12 is started. Through the extension and retraction of the cylinder 12 extension end, the L-shaped bracket 4 is driven to move up and down in the inner cavity of the slide groove 11. When picking up the material, the cylinder 12 extension end is shortened, so that the L-shaped bracket 4 descends, driving the two load-bearing frames 62 to be lowered to the side of the wheel hub. Then, the motor 9 is started. The motor 9 drives the bidirectional screw 7 to rotate. Since the two spiral grooves 8 on its surface rotate in opposite directions, when rotating, the connecting roller 66 connected to the inner cavity moves with the rotation direction of the spiral grooves 8, driving the two movable frames 61 to move on the surface of the crossbar 5 at the same speed and in opposite directions. At the same time, the two spiral grooves 8 With equal screw pitches, the distance between the two support frames 62 changes equidistantly as the bidirectional screw 7 rotates. Adjusting the distance between the two support frames 62 according to the specific dimensions of the wheel hub allows for the fixed feeding operation of wheel hubs of different sizes. The motor 9 is turned off after the four side clamping rollers 64 contact the wheel hub surface. The wheel hub is then clamped and fixed by the four clamping rollers 64 in a rectangular array. Silicone gaskets 65 are added to reduce the risk of collisions between the clamping rollers 64 and the wheel hub surface, and also to prevent excessive clamping force from causing deformation of the wheel hub surface. After clamping and fixing, the cylinder 12 is restarted, controlling the extension end of the cylinder 12 to extend, causing the L-shaped bracket 4 to rise and cooperate with the linear guide rail 2 to achieve the feeding operation of the wheel hub. The entire process requires no manual intervention, effectively realizing the automated operation of the device.
