Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically a polishing device for the production of automotive exterior parts. Background Technology

[0002] Automotive exterior parts include front and rear bumpers, wheel arches, air intake grilles, radiator grilles, rearview mirrors, pillar trim panels, roof racks, door handles, sunroofs, wipers, and rear spoilers. These exterior parts are not only an important part of the vehicle's appearance but also serve a variety of practical functions. For example, during the production and processing of automotive exterior roof racks, polishing equipment is used to polish them. Polished roof racks can significantly improve in terms of appearance, functionality, and durability.

[0003] Because the polishing device used for polishing car roof racks can only polish one side at a time, and after one side is polished, the staff needs to turn the car roof rack over and polish it again, which is inconvenient. Therefore, we have proposed a polishing device for the production of automotive exterior parts to solve the above problems. Utility Model Content

Three polishing rollers are fixed to the surface of the rotating shaft. Two rotating shafts are rotatably connected to the bottom of each connecting seat via bearings. Polishing rollers are fixed to the surface of each rotating shaft. Six driving bevel gears are fixed to the surface of the rotating shaft, and driven bevel gears are fixed to the surface of each rotating shaft. The driven bevel gears mesh with their corresponding driving bevel gears.

[0009] Furthermore, the clamping mechanism includes six U-shaped plates fixed to the top of the workbench. Each U-shaped plate has a through slot at its top, in which two clamping blocks are slidably connected. The bottom of each clamping block is rotatably connected to a connecting rod via a pin. The bottom of the workbench has two hydraulic push rods (II), and the protruding ends of the two hydraulic push rods (II) are fixed to I-shaped plates. The top of the I-shaped plates has six push rods (P), and the top ends of each push rod slide through the workbench and extend above it, where they are fixed to connecting plates. The bottom ends of the connecting rods are rotatably connected to the corresponding connecting plates via pins.

[0010] Furthermore, each side wall of the clamping block is fixed with an anti-slip pad, which is made of rubber.

[0011] Furthermore, dust collection hoods are fixed to both sides of the horizontal plate, and dust collection pipes are fixedly connected to the two dust collection hoods.

[0012] Furthermore, each lead screw has a sprocket fixed to its surface, and the two sprockets are connected by a chain drive.

[0013] Furthermore, guide rods are installed inside the two through holes at the top of the movable seat, and the bottom ends of the guide rods are fixedly connected to the horizontal plate.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a polishing device for the production of automotive exterior parts, which has the following beneficial effects:

Detailed Implementation

[0022] 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.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an embodiment of this utility model discloses a polishing device for the production of automotive exterior parts, including a worktable 1. A clamping mechanism 2 and two support plates 3 are mounted on the worktable 1. Two lead screws 4 are rotatably connected to the two support plates 3 via bearings. Each lead screw 4 has a sprocket 17 fixed to its surface. The two sprockets 17 are connected by a chain 18, allowing the two lead screws 4 to rotate synchronously under the action of a single motor, thereby saving production costs. A movable seat 5 is threaded onto the surface of the two lead screws 4. A hydraulic push rod 6 is fixed to the top of the movable seat 5. The hydraulic push rod 6 has a self-locking function, allowing it to remain firmly in place after the movable seat 5 moves up and down to a designated position, preventing damage from external impacts, vibrations, or pressure fluctuations. The displacement caused by this effectively improves safety and reliability. The top end of the hydraulic push rod 6 slides through the moving seat 5 and extends below it, where a horizontal plate 7 is fixed. Guide rods 19 are installed inside the two through holes at the top of the moving seat 5. The bottom ends of the guide rods 19 are fixedly connected to the horizontal plate 7, providing auxiliary guidance and support for the horizontal plate 7, making it more stable during vertical movement. Three connecting seats 8 are fixed to the bottom of the horizontal plate 7. A rotating shaft 9 is rotatably connected between the three connecting seats 8 via bearings. Three polishing rollers 10 are fixed to the surface of the rotating shaft 9. Two rotating shafts 11 are rotatably connected to the bottom of each connecting seat 8 via bearings. Polishing rollers 12 are fixed to the surface of each rotating shaft 11. Six driving bevel gears 13 are fixed to the surface of the rotating shaft 9. Each surface of the rotating shaft 11 is fixed with a driven bevel gear 14, which meshes with the corresponding driving bevel gear 13. During the polishing process using this polishing device for automotive exterior parts production, since the bottom of the automotive exterior roof rack has two grooves, during polishing, simply place a certain number of roof racks on the clamping mechanism 2 as shown in the figure. Then, operate the clamping mechanism 2 to clamp and fix multiple roof racks. After the roof racks are clamped, a rubber hammer can be used to gently tap each roof rack to prevent unevenness after clamping. Then, the motor can be started to drive the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 will drive the polishing roller 10 to rotate, and the rotation of the rotating shaft 9 will drive the six driving bevel gears 13 to rotate. After the bevel gear 13 rotates, it drives the driven bevel gear 14 to rotate. The driven bevel gear 14 then drives the rotating shaft 11 to rotate, which in turn drives the polishing roller 12 to rotate. Next, the hydraulic push rod 6 is activated to move the moving seat 5 downwards. The downward movement of the moving seat 5 then drives the rotating polishing rollers 10 and 12 downwards. Once the polishing rollers 10 and 12 have moved downwards, they will contact and polish the upper surface and two side surfaces of the car roof rack. During polishing, the motor drives the lead screw 4 to rotate, which in turn drives the moving seat 5 to move laterally. This allows for the overall polishing of the clamped car roof rack. Since the car exterior roof rack is arc-shaped, the height of the lateral sliding moving seat 5 can be adjusted vertically using the hydraulic push rod 6.Then, the heights of the multiple polishing rollers 10 and 12 are adjusted.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the clamping mechanism 2 includes six U-shaped plates 201 fixed to the top of the workbench 1. Each U-shaped plate 201 has a through slot at its top, and two clamping blocks 202 are slidably connected to it. The bottom of each clamping block 202 is rotatably connected to a connecting rod 203 via a pin. Two hydraulic push rods 204 are fixed to the bottom of the workbench 1. These two hydraulic push rods 204 have a self-locking function, allowing them to be stably held after the I-beam 205 reaches the designated position, preventing damage from external impacts or vibrations. Displacement caused by dynamic or pressure fluctuations effectively improves safety and reliability. Two hydraulic push rods 204 have I-shaped plates 205 fixed to their protruding ends. Six push rods 206 are fixed to the top of the I-shaped plates 205. The top ends of the push rods 206 slide through the worktable 1, extending above it and being fixed with connecting plates 207. The bottom ends of the connecting rods 203 are rotatably connected to the corresponding connecting plates 207 via pins. Anti-slip pads 208, made of rubber, are fixed to one side wall of the clamping block 202. The anti-slip pads 208 ensure greater stability of the car roof rack after it is secured by the clamping blocks 202, while also providing protection by preventing direct contact between the inner surface of the car roof rack and the clamping blocks 202, thus avoiding damage. In use, one end of the car roof rack is placed on the surface of the two clamping blocks 202 on the same U-shaped plate 201, and the other end is placed on the two clamping blocks 202 on the U-shaped plate 201 that are laterally aligned with it. Once a certain number of car roof racks have been placed, this… When the two hydraulic push rods 204 are activated, the top ends of the push rods 204 can be used to push the I-shaped plate 205 upward. After the I-shaped plate 205 is moved upward, the push rod 206 can drive the six connecting plates 207 upward. After the connecting plates 207 are moved upward, with the cooperation of the connecting rod 203, the two clamping blocks 202 on the same U-shaped plate 201 can be driven to move in opposite directions synchronously. At this time, the car roof rack can be clamped and fixed. When it is necessary to release the car roof rack, it is only necessary to drive the two hydraulic push rods 204 to move the I-shaped plate 205 downward.

[0026] like Figure 2 As shown, in some embodiments, dust collection hoods 15 are fixed on both sides of the horizontal plate 7, and dust collection pipes 16 are fixedly connected to the two dust collection hoods 15. This allows the dust generated during polishing of the car roof rack to be collected by the dust collection hoods 15, preventing it from spreading everywhere. In use, simply connect the inlet hose of the vacuum cleaner to the dust collection pipe 16.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
