Description

Technical Field

[0001] This invention relates to the field of seat belt bracket repair technology, specifically to a surface repair device for remanufacturing automotive seat belt brackets. Background Technology

[0002] The existing defects of automotive seat belt bracket surface processing devices are: 1. When processing the bracket surface, the existing bracket surface processing devices require manual adjustment of the bracket's direction, which makes them less practical; 2. The existing bracket surface processing devices cannot process multiple parts of the bracket surface at the same time, resulting in low processing efficiency.

[0003] Chinese patent CN217475254U discloses a surface processing device for automotive seat belt wire brackets, including a chassis. A foot is fixedly connected to the bottom of the chassis. A mounting plate is provided on the outer side of the chassis and is fixedly connected to the chassis. A protective cover is provided on the top of the chassis and is fixedly connected to the chassis. A motor is housed inside the protective cover. A turntable is provided on the top of the motor and is threadedly connected to the motor. Adhesive is applied to the top surface of the turntable and is bonded to the turntable. The outer surface of the protective cover... The device has a guide rail on one side, with a protective pad on the outer side of the guide rail and a fixed connection between the protective pad and the chassis. An electric push rod is fixedly connected inside the guide rail, and a support rod is provided at the top of the electric push rod. The support rod and the electric push rod are connected by a slider. A hexagonal frame is provided on one side of the support rod and is fixedly connected to the support rod. A cylinder is fixedly connected to the inner side of the hexagonal frame. A carrier plate is provided at the end of the cylinder and is threadedly connected to the cylinder. A silicone pad is provided on one side of the carrier plate and is fixedly connected to the carrier plate.

[0004] Chinese patent CN218558793U discloses a seat belt bracket. According to the shape of the bracket, although the above-mentioned processing device can hold the seat belt bracket, it cannot hold it stably. This is because the force point of the bracket is very small. When the carrier clamps the side wall of the bracket, the force changes during grinding, which will inevitably cause the bracket to slip and tilt. Summary of the Invention

[0005] To address the aforementioned issues, a surface repair device for remanufacturing automotive seatbelt brackets is provided. The seatbelt bracket to be repaired is placed on a support bracket, with the rotating plate in a vertical position, allowing the bracket to be installed. Once the bracket is fully positioned, an activation device at the bottom of the bracket is activated. This activation device, controlled by a controller, starts a drive unit, which rotates the clamping wheels and moves the support bracket along the height of the mounting frame. The two clamping wheels hold the sides of the bracket, while the rotating plate and the bottom of the support bracket hold the top and bottom. The vertical rotating plate gradually rotates to a horizontal position under the action of the transmission assembly. A locking device then locks the horizontal rotation. At this point, the horizontal rotating plate and the support bracket together hold the top and bottom of the bracket. Because the bracket is stably clamped on all four sides, the repair process is ensured, preventing the bracket from shaking or slipping, and facilitating placement and removal.

Detailed Implementation

[0035] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figure 1 , Figure 2 and Figure 13 A surface repair device for remanufacturing automotive seatbelt brackets includes a mounting frame 1, a clamping device 2, and a repair device. The clamping device 2 includes a support frame 21, a locking device 22, a rotating plate 23, clamping wheels 24, a drive device 25, a transmission assembly 26, and an activation device 27. The support frame 21 is slidably disposed within the mounting frame 1 along its height direction and is used to support the seatbelt bracket 3. The rotating plate 23 is rotatably disposed on the upper part of the support frame 21. The transmission assembly 26 is disposed on one side of the rotating plate 23 and on the mounting frame 1. When the support frame 21 slides along its height direction, the rotating plate 23 rotates and clamps the seatbelt bracket 3 located on the support frame 21. The locking device 22 is disposed on one side of the rotating plate 23 and on the mounting frame 1. The locking device 22, located on the rotating plate 23 and the transmission assembly 26, can lock the rotating plate 23 when it is in a horizontal state. There are two clamping wheels 24, which are symmetrically arranged on the mounting frame 1 about the support frame 21. The axes of the clamping wheels 24 are parallel to the horizontal plane. The driving device 25 is located on one side of the clamping wheels 24. The driving device 25 drives the clamping wheels 24 to rotate and also drives the support frame 21 to rise and fall. The activation device 27 is located at the lower part of the support frame 21. The activation device 27 can be activated by the seat belt bracket 3 placed on the support frame 21. A controller is located on one side of the activation device 27. The activation device 27 controls the operation of the driving device 25 through the controller.

[0037] The repair device is located on one side of the mounting bracket 1. This device can repair the seatbelt bracket 3 located on the support bracket 21. In use, the seatbelt bracket 3 to be repaired is placed on the support bracket 21, with the rotating plate 23 in a vertical position. It is important to note that the seatbelt bracket 3 must also be placed vertically, ensuring that the peripheral wall of the clamping wheel 24 contacts the side wall of the seatbelt bracket 3. After the seatbelt bracket 3 is fully placed on the support bracket 21, the activation device 27 located at the bottom of the support bracket 21 is activated. The activation device 27 controls the drive device 25 to start via a controller. The drive device 25 drives the clamping wheel 24 to rotate, and simultaneously... The support bracket 21 can move along the height direction of the mounting frame 1. Since the two clamping wheels 24 clamp the two sides of the seat belt bracket 3, and the bottom of the rotating plate 23 and the support bracket 21 clamp the upper and lower sides of the seat belt bracket 3, the rotating plate 23, which is in a vertical state, gradually rotates to a horizontal state under the action of the transmission component 26. The locking device 22 locks the rotation in the horizontal state. At this time, the rotating plate 23 and the support bracket 21, which are in a horizontal state, together clamp the upper and lower sides of the seat belt bracket 3. Since the seat belt bracket 3 is stably clamped on all four sides, it is ensured that the seat belt bracket 3 will not shake or slip during repair, and it is also convenient to place and pick up the seat belt bracket 3. After the repair device finishes grinding the seat belt bracket 3, the drive device 25 rotates in the opposite direction. The drive device 25 drives the support frame 21 to move upward along the height direction of the mounting frame 1. At the same time, the clamping wheel 24 also provides support for the seat belt bracket 3. When the rotating plate 23 is about to reach the transmission component 26 located on the mounting frame 1, the locking device 22 unlocks. At the same time, as the support frame 21 continues to rise, the rotating plate 23 will gradually rotate to a vertical state under the action of the transmission component 26. In this way, the staff can easily remove the seat belt bracket 3.

[0038] Reference Figure 1 and Figure 4 The transmission assembly 26 includes a first gear 261, a first rack 262, and a first limiting plate 263. The first gear 261 is fixedly disposed on one side of the rotating plate 23 along the rotation axis of the rotating plate 23. The first rack 262 is fixedly disposed on the mounting bracket 1 on one side of the first gear 261 along the height direction of the mounting bracket 1, and the first rack 262 and the first gear 261 mesh with each other. The first limiting plate 263 is horizontally fixedly disposed on the support bracket 21 below the rotating plate 23, and the first limiting plate 263 is used to limit the rotation angle of the rotating plate 23.

[0039] When the seat belt bracket 3 is placed on the support frame 21 and the support frame 21 descends, the first gear 261 descends along with the support frame 21. The first gear 261 rotates under the action of the first rack 262. Since the first gear 261 is fixedly connected to the rotating plate 23, the rotating plate 23 can be driven to rotate by the first gear 261. At this time, the rotating plate 23, which is in a vertical state, will gradually rotate to a horizontal state. At the same time, the first limiting plate 263 can limit the rotating plate 23, ensuring that the first limiting plate 263 can rotate to a horizontal state, and ensuring that the locking device 22 can restrict the rotating plate 23, which is in a horizontal state.

[0040] Reference Figure 2 , Figure 11 and Figure 14 The locking device 22 includes a spring 221, a locking block 222, and a locking groove 223. A groove is provided on the side of the rotating plate 23 near the first gear 261 along the axis of the first gear 261. The projection of the groove on the first gear 261 is at a non-central position. The locking block 222 is slidably disposed in the groove along the length direction of the groove, and there is a gap between the locking block 222 and the bottom of the groove. The spring 221 is disposed in the gap. The locking groove 223 is provided on the side of the first gear 261 near the rotating plate 23 along the length direction of the groove. A support frame 21 is spaced between the first gear 261 and the rotating plate 23. A through groove is provided on the support frame 21. When the rotating plate 23 is in a horizontal state, the groove and the through groove coincide, and the locking groove 223 and the locking block 222 engage.

[0041] When the rotating plate 23 rotates to a horizontal position, the snap-fit ​​block 222 located in the groove of the rotating plate 23 passes through the through slot under the elastic force of the spring 221 and snaps into the snap-fit ​​slot 223. In this way, the rotating plate 23 will not rotate during the subsequent descent of the support frame 21.

[0042] Reference Figure 1 and Figure 2 The locking device 22 also includes a magnetic plate 224; the snap-fit ​​block 222 has magnetism, and the magnetism on the magnetic plate 224 is the same as that on the snap-fit ​​block 222. The magnetic plate 224 is located on one side of the first gear 261 at the lower part of the first rack 262.

[0043] When the support frame 21 descends, although the locking block 222 will pass by the magnetic plate 224, since the rotating plate 23 is already in a horizontal state, even if the locking block 222 briefly disengages from the locking groove 223 under the action of the magnetic plate 224, it will not have any impact. When the support frame 21 rises, the magnetic plate 224 generates a repulsive force on the locking block 222, and the locking block 222 slides back into the groove under the action of the repulsive force. Then the first gear 261 will mesh with the first rack 262, and the first gear 261 will rotate under the drive of the first rack 262.

[0044] Reference Figure 5 The clamping device 2 also includes a clamping protection device 241, which includes an air pump 2411, an elastic diaphragm 2412, and a connecting pipe 2413. An annular groove is formed on the clamping wheel 24 along its axis. The annular groove is used to clamp the seat belt bracket 3. The elastic diaphragm 2412 has an annular structure and is set in the annular groove along the axis of the clamping wheel 24. The elastic diaphragm 2412 and the annular groove form a cavity. The air pump 2411 is set on one side of the clamping wheel 24. The two ends of the connecting pipe 2413 are connected to the air pump 2411 and the clamping wheel 24, respectively. The end of the connecting pipe 2413 away from the air pump 2411 is connected to the cavity. The air pump 2411 can pump gas into the cavity.

[0045] When the air pump 2411 is started, it pumps gas into the cavity through the connecting pipe 2413. The elastic diaphragm 2412 gradually bulges up. The side of the bulging elastic diaphragm 2412 that contacts the seat belt bracket 3 gradually deforms, that is, the contact area between the elastic diaphragm 2412 and the seat belt bracket 3 increases. This increases the friction between the elastic diaphragm 2412 and the seat belt bracket 3, reducing the wear on the elastic diaphragm 2412 caused by the shaking caused by the vibration of the seat belt bracket 3 during repair. At the same time, the elastic diaphragm 2412 can reduce the impact of vibration on the clamping wheel 24, avoiding wear of the clamping wheel 24 during the clamping process.

[0046] Reference Figure 1 and Figure 2 The drive unit 25 includes a rotary driver 251, a second gear 252, and a third gear 253.

[0047] Two second gears 252 are provided, and the two second gears 252 are fixedly disposed at the same end of the two clamping wheels 24 along the axis of the two clamping wheels 24, and the two second gears 252 mesh with each other; the third gear 253 is disposed on one side of the second gear 252, and the third gear 253 meshes with the second gear 252; the rotary driver 251 is disposed at the end of the third gear 253, and the rotary driver 251 drives the third gear 253 to rotate.

[0048] The rotary driver 251 is preferably a servo motor. When the rotary driver 251 is started, it drives the second gear 252 to rotate through the third gear 253 set on its output end. The third gear 253 drives one of the second gears 252 to rotate. The two second gears 252 are meshed with each other, so both second gears 252 will rotate, causing the two clamping wheels 24 set at the ends of the two second gears 252 to rotate. The clamping wheels 24 can drive the seat belt bracket 3 to move. At the same time, the rotating clamping wheels 24 can also drive the support frame 21 to move along the height direction of the mounting frame 1.

[0049] Reference Figures 6-9 The clamping device 2 also includes a toothed ring 242 and a second rack 243; the toothed ring 242 is fixedly mounted on the clamping wheel 24 along the axis of the clamping wheel 24; the second rack 243 is fixedly mounted on the side of the support frame 21 near the mounting frame 1 along the height direction of the support frame 21, and the second rack 243 and the toothed ring 242 mesh with each other.

[0050] When the drive device 25 drives the clamping wheel 24 to rotate, since the clamping wheel 24 and the toothed ring 242 are fixedly connected, the toothed ring 242 will also be driven to rotate by the clamping wheel 24. The toothed ring 242 drives the second rack 243 to move. As the toothed ring 242 rotates, the second rack 243 drives the support to slide along the height direction of the mounting base.

[0051] Reference Figures 6-9 The clamping device 2 also includes a second limiting plate 244, a third limiting plate 245, and a guide rail 246; the second limiting plate 244 is fixedly disposed on the upper part of the second rack 243; the third limiting plate 245 is fixedly disposed on the lower part of the mounting frame 1; the guide rail 246 is fixedly disposed on the side wall of the mounting frame 1 along the height direction of the mounting frame 1, the guide rail 246 slides with the support frame 21, and the guide rail 246 can contact the second limiting plate 244.

[0052] When the support bracket 21 slides upward along the height direction of the mounting frame 1 under the drive of the drive device 25, the bottom of the support bracket 21 will contact the third limiting plate 245 set at the lower part of the mounting frame 1. At this time, the support bracket 21 can no longer slide. At the same time, when the support bracket 21 descends, the support bracket 21 slides on the guide rail 246. The second limiting plate 244 set on the support bracket 21 gradually moves closer to the end of the guide rail 246. Finally, the second limiting plate 244 will contact the end of the guide rail 246, so the support bracket 21 can no longer descend.

[0053] Reference Figure 12 and Figure 13 The activation device 27 includes a button 271; the button 271 is located at the bottom of the support frame 21.

[0054] When the seat belt bracket 3 is placed on the support frame 21, the weight of the seat belt bracket 3 acts on the button 271. The button 271 is pressed under the weight of the seat belt bracket 3. The button 271 controls the drive device 25 to start through the controller. After starting, the drive device 25 drives the clamping wheel 24 to rotate and also drives the support frame 21 to move.

[0055] Reference Figure 9 and Figure 10 The clamping device 2 also includes a camera 28; the camera 28 is fixedly mounted on the mounting bracket 1, and the output end of the camera 28 points towards the support bracket 21.

[0056] After the seat belt bracket 3 is placed on the support frame 21, the drive device 25 drives the support frame 21 to slide along the height direction of the mounting frame 1. The camera 28 can then scan the seat belt bracket 3 on the sliding support frame 21. The repair device set on one side of the mounting frame 1 can then polish and repair the seat belt bracket 3 on the support frame 21 based on the image captured by the camera 28.

[0057] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
