Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, specifically an automotive parts surface treatment device. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the car. There are many types of automotive parts. As people's living standards improve, people's consumption of cars is also increasing, and the market for automotive parts is becoming larger and larger. The surface treatment of automotive parts includes processes such as painting, grinding and polishing, cleaning and drying. Among them, the surface of some stamped parts in the car needs to be ground and polished.

[0003] A search revealed that patent CN220463249U discloses a device for removing burrs from the surface of automotive parts. The device includes a platform with a support frame welded to one end at the top center. A transmission box is fixed to the end of the support frame away from the platform. A groove is formed at the center of the top of the transmission box, and a rod is slidably connected inside the groove. A limiting groove is formed on one side of the rod, and a toothed plate is welded inside the limiting groove. A worm gear is movably connected to the transversely adjacent inner wall of the transmission box via bearings, and a transmission shaft is movably connected to the longitudinally adjacent inner wall of the transmission box via bearings. In this invention, a handwheel drives the worm gear to mesh with a worm wheel, which in turn drives the transmission shaft to rotate. The transmission shaft then drives the gear to mesh with the toothed plate, allowing the toothed plate to move the rod along the groove and lift a cover cylinder. This facilitates the cover cylinder being placed over the exterior of the automotive parts for efficient burr removal using a polishing brush.

[0004] Analysis of the above technical solutions reveals that automotive parts often require grinding in different areas, necessitating flipping. However, the existing solutions only grind the top of the workpiece; the remaining areas require manual removal, flipping, and re-fixing, which is cumbersome and increases the workload for workers. Therefore, we provide an automotive parts surface treatment device to address these issues. Utility Model Content

[0007] Preferably, the grinding mechanism includes a hydraulic cylinder, which is mounted on the top of the bracket. A first motor is fixedly connected to the telescopic end of the hydraulic cylinder, and a grinding disc is fixedly connected to the output end of the first motor.

[0008] Preferably, the displacement mechanism includes an X-axis linear module and a Y-axis linear module. The X-axis linear module is fixedly connected to the base, the Y-axis linear module is mounted on the slide of the X-axis linear module, and the bottom surface of the moving frame is fixedly connected to the slide of the Y-axis linear module.

[0009] Preferably, the clamping mechanism includes a second motor and a bidirectional lead screw.

The output end of the second motor is connected to the bidirectional lead screw. Two opposing movable plates are slidably arranged on the inner wall of the movable frame, and the bottom ends of the two movable plates are threaded onto the surface of the bidirectional lead screw. Rotary cylinders are rotatably connected to the two movable plates, and clamping plates are fixedly connected to the adjacent ends of the two rotary cylinders.

[0010] Preferably, the swing mechanism includes an L-shaped plate and a U-shaped plate. The L-shaped plate is fixedly connected to the front of the moving frame. A third motor is installed at the front end of the L-shaped plate. A screw is fixedly connected to the output end of the third motor, and the rear end of the screw is rotatably connected to the front of the moving frame. The middle part of the U-shaped plate is threaded onto the surface of the screw. Toothed plates are fixedly connected to both ends of the U-shaped plate. Two opposing support blocks are fixedly connected to the moving frame. Gears are rotatably connected to the top ends of the two support blocks, and the toothed plates mesh with the gears.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through the coordinated arrangement of a grinding mechanism, a displacement mechanism, a moving frame, a clamping mechanism, and a swinging mechanism, firstly uses the operation of a second motor to clamp and fix the workpiece with two clamping plates. Then, the operation of the X-axis linear module and the Y-axis linear module moves the workpiece to directly below the grinding mechanism. The operation of the hydraulic cylinder controls the raising and lowering of the grinding disc and the grinding belt. Next, the first motor is started to grind the top of the workpiece with the grinding disc. When the workpiece moves to one side of the grinding belt, the grinding belt can be used to grind the side of the workpiece, making the grinding more comprehensive. When it is necessary to control the rotation and adjustment position of the workpiece between the two clamping plates, the third motor drives the screw to rotate, thereby controlling the movement of the U-shaped plate. This further causes the two toothed plates to simultaneously drive the two gears to rotate, causing the rotating shaft to drive the rotating cylinder to rotate on the moving plate, thus realizing the control of the rotation of the workpiece between the two clamping plates. The operation is more convenient, thus eliminating the need for frequent manual adjustment of the workpiece clamping position. Attached Figure Description

[0026] 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.

[0027] Example 1, as Figure 1-9 As shown, this embodiment proposes a surface treatment device for automotive parts, including a base 1, a support 2 fixedly connected to the base 1, and a grinding mechanism 3 provided at the top of the support 2. The grinding mechanism 3 is used to grind the workpiece on the base 1, and can grind the top and sides of the workpiece, thereby improving the surface treatment efficiency. A displacement mechanism 4 is provided on the base 1, and a moving frame 5 is provided on the displacement mechanism 4. The movement of the moving frame 5 on the base 1 can be controlled by the operation of the displacement mechanism 4 to move in the X and Y directions, thereby grinding different positions of the workpiece on the moving frame 5. The device is more flexible in use. The moving frame 5 is equipped with a clamping mechanism 6 for fixing the workpiece and a swinging mechanism 7 for controlling the rotation of the workpiece. With the clamping mechanism 6 and the swinging mechanism 7, the workpiece can be fixed above the moving frame 5 by the clamping mechanism 6. When it is necessary to change the grinding surface of the workpiece, the workpiece can be flipped over by simply using the swinging mechanism 7 without having to be removed again, making the operation more convenient. The machinery, parts and equipment in this device all adopt conventional models in the existing technology. In addition, the circuit connection adopts conventional connection methods in the existing technology, which will not be described in detail here.

[0028] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. See the description below for details:

[0029] like Figure 1As shown, the grinding mechanism 3 includes a hydraulic cylinder 301, which is mounted on the top of the bracket 2. The telescopic end of the hydraulic cylinder 301 is fixedly connected to a first motor 303, and the output end of the first motor 303 is fixedly connected to a grinding disc 302. A grinding belt 304 is fixedly connected to the side of the grinding disc 302. Both the grinding disc 302 and the grinding belt 304 are existing mature components and will not be described in detail here. With the above structure, the operation of the hydraulic cylinder 301 can control the lifting and lowering of the grinding disc 302 and the grinding belt 304, so as to facilitate subsequent grinding of the top or side of the workpiece. The bottom surface of the grinding disc 302 can grind the top of the workpiece, while the grinding belt 304 can grind the side of the workpiece, thus eliminating the need for frequent manual adjustment of the workpiece clamping position.

[0030] like Figure 1 and Figure 8 As shown, the displacement mechanism 4 includes an X-axis linear module 41 and a Y-axis linear module 42. The X-axis linear module 41 is fixedly connected to the base 1, and the Y-axis linear module 42 is mounted on the slide of the X-axis linear module 41. The bottom surface of the moving frame 5 is fixedly connected to the slide of the Y-axis linear module 42. With the above structure, the X-axis linear module 41 can drive the moving frame 5 and the Y-axis linear module 42 to move in the X-axis direction, and the Y-axis linear module 42 can drive the moving frame 5 to move in the Y-axis direction. This allows for more flexible adjustment of the workpiece's grinding position. Combined with the use of the grinding mechanism 3, it greatly improves the grinding efficiency of the workpiece. Both the X-axis linear module 41 and the Y-axis linear module 42 are existing mature technologies.

[0031] like Figures 1 to 3 and Figure 5 As shown, the clamping mechanism 6 includes a second motor 65 and a bidirectional lead screw 64. The second motor 65 is mounted on the inner wall of the movable frame 5, and the bidirectional lead screw 64 is rotatably connected to the inner wall of the movable frame 5. The output end of the second motor 65 is connected to the bidirectional lead screw 64. Two opposing movable plates 61 are slidably arranged on the inner wall of the movable frame 5, and the bottom ends of the two movable plates 61 are threaded onto the surface of the bidirectional lead screw 64. Rotary cylinders 62 are rotatably connected to the two movable plates 61, and clamping plates 63 are fixedly connected to the adjacent ends of the two rotary cylinders 62. With the above structure, the workpiece is placed between the two clamping plates 63. Then, the operation of the second motor 65 controls the two movable plates 61 to move closer to each other, further clamping and fixing the workpiece with the two clamping plates 63. Since the rotary cylinders 62 are rotatably arranged on the movable plates 61, the workpiece between the two clamping plates 63 will also rotate when the rotary cylinders 62 rotate.

[0032] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 9 As shown, the swing mechanism 7 includes an L-shaped plate 77 and a U-shaped plate 75. The L-shaped plate 77 is fixedly connected to the front of the moving frame 5. A third motor 79 is installed at the front end of the L-shaped plate 77. A screw 78 is fixedly connected to the output end of the third motor 79, and the rear end of the screw 78 is rotatably connected to the front of the moving frame 5. The middle part of the U-shaped plate 75 is threaded onto the surface of the screw 78. Both ends of the U-shaped plate 75 are fixedly connected to toothed plates 74. Two opposing support blocks 73 are fixedly connected to the moving frame 5. Gears 72 are rotatably connected to the top of each of the two support blocks 73, and the toothed plates 74 mesh with the gears 72. Each adjacent side is fixedly connected to a rotating shaft 71, and the two rotating shafts 71 are slidably inserted into the two rotating cylinders 62 respectively. With the above structure, when it is necessary to control the rotation and position adjustment of the workpiece between the two clamping plates 63, it is only necessary to use the third motor 79 to drive the screw 78 to rotate, thereby controlling the U-shaped plate 75 to move, and further causing the two toothed plates 74 to simultaneously drive the two gears 72 to rotate, so that the rotating shaft 71 drives the rotating cylinder 62 to rotate on the moving plate 61, thereby realizing the control of the rotation of the workpiece between the two clamping plates 63. The operation is more convenient, and there is no need to remove the workpiece and clamp it again.

[0033] like Figure 1 and Figure 8 As shown, the bottom surface of the Y-axis linear module 42 is fixedly connected to two rollers. The base 1 is provided with a sliding groove that matches the two rollers, and the two rollers slide in the two sliding grooves respectively. With the above structure, the Y-axis linear module 42 is more stable when moving in the Y-axis direction, and the grinding debris can be easily cleaned when it falls into the sliding groove, and will not accumulate in the sliding groove.

[0034] like Figure 2 , Figure 4 , Figure 7 and Figure 9 As shown, guide grooves are provided on the bottom surfaces of both toothed plates 74, and guide blocks are fixedly connected to both support blocks 73. The guide blocks are inserted into the guide grooves. With the above structure, the toothed plates 74 can slide stably on the support blocks 73, thereby preventing the toothed plates 74 and gears 72 from tilting, thus ensuring the meshing stability of the toothed plates 74 and gears 72.

[0035] like Figure 1 and Figure 2 As shown, two opposing guide rods 76 are fixedly connected to the front of the movable frame 5, and the U-shaped plate 75 is slidably sleeved on the two guide rods 76. With the above structure, the stability of the movement of the U-shaped plate 75 can be guaranteed, and the deformation of the U-shaped plate 75 can be avoided during the grinding process of the workpiece.

[0036] The working principle and usage process of this utility model are as follows: First, the workpiece is placed between two clamping plates 63. Then, the operation of the second motor 65 controls the two moving plates 61 to move closer to each other, further clamping and fixing the workpiece with the two clamping plates 63. Then, the operation of the Y-axis linear module 42 moves the workpiece to the bottom of the grinding disc 302. Subsequently, the operation of the hydraulic cylinder 301 controls the descent of the grinding disc 302 and the grinding belt 304. Then, the first motor 303 is started to drive the grinding disc 302 and the grinding belt 304 to rotate together, so that the grinding disc 302 can grind the top of the workpiece. When the workpiece moves to the grinding disc 302 through the X-axis linear module 41, the grinding disc 302 can grind the top of the workpiece. When grinding one side of the grinding belt 304, the grinding belt 304 can be lowered by using the hydraulic cylinder 301 to grind the side of the workpiece. This eliminates the need for frequent manual adjustment of the workpiece clamping position. When the workpiece needs to be flipped for adjustment, the workpiece can be rotated between the two clamping plates 63. The third motor 79 drives the screw 78 to rotate, which in turn controls the U-shaped plate 75 to move. This further causes the two toothed plates 74 to simultaneously drive the two gears 72 to rotate, so that the rotating shaft 71 drives the rotating drum 62 to rotate on the moving plate 61, thereby achieving the rotation of the workpiece. The operation is more convenient, and there is no need to remove the workpiece and clamp it again.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
