[0001] This utility model relates to the field of automotive parts processing technology, and in particular to an automotive parts grinding workbench with workpiece positioning function. Background Technology

[0002] Automotive parts refer to the various unit components that make up a car as a whole, as well as all consumable materials that serve the car, including core components such as engines, transmission systems, and braking systems, as well as auxiliary components such as interior and exterior trim.

[0003] In the production and processing of automotive parts, the grinding process is a crucial step in ensuring the surface quality of the parts. Its processing accuracy directly affects the subsequent assembly and performance of the automotive parts. Currently, the existing automotive parts grinding worktables on the market have simple workpiece positioning structures, mostly using fixed clamping methods. They cannot be flexibly adjusted according to different specifications and shapes of automotive parts, resulting in poor versatility and poor positioning stability. During the grinding process, the workpiece is prone to displacement or shaking, leading to a decrease in grinding accuracy and problems such as uneven surface and excessive dimensional errors. Therefore, it is necessary to redesign an automotive parts grinding worktable with workpiece positioning function to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a grinding workbench for automotive parts with workpiece positioning function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A grinding workbench for automotive parts with workpiece positioning function includes a workbench body. The bottom wall of the workbench body is fixedly fitted with shock-absorbing pads via multiple support legs. A bidirectional screw is rotatably mounted on the bottom wall of the workbench body via a movable frame. A first motor connected to the bidirectional screw is fixedly mounted on the outer wall of the movable frame. A limit rod is fixedly mounted inside the movable frame. Two movable sleeves are threaded onto the outer wall of the bidirectional screw. The limit rod slides through the two movable sleeves. Mounting plates are fixedly mounted on the bottom walls of both movable sleeves via a connecting mechanism. Each wall is fixedly mounted with a positioning frame via a rotating rod. A second motor connected to one of the rotating rods is fixedly mounted on the outer wall of one of the mounting plates. Cylinders are fixedly mounted on the upper surfaces of both positioning frames via mounting frames. Positioning plates are fixedly mounted on the telescopic ends of both cylinders. A one-way screw is rotatably mounted on the upper surface of the worktable body via a lifting frame. A third motor connected to the one-way screw is fixedly mounted on the upper surface of the lifting frame. A moving block is threadedly mounted on the outer wall of the one-way screw via a stabilizing mechanism. A grinding device is fixedly mounted on the outer wall of the moving block via a connecting mechanism.

[0007] Preferably, the connecting mechanism includes a connecting plate fixedly installed on the bottom wall of the movable sleeve, and the end of the connecting plate is fixedly connected to the outer wall of the mounting plate.

[0008] Preferably, the stabilizing mechanism includes a stabilizing rod fixedly installed inside the lifting frame, the stabilizing rod sliding through the moving block.

[0009] Preferably, the connecting mechanism includes a connecting rod fixedly installed on the outer wall of the movable block, and the end of the connecting rod is fixedly connected to the upper end face of the grinding device.

[0010] Preferably, a first anti-slip pad is fixedly installed on the bottom wall of each of the two positioning frames, and two second anti-slip pads are fixedly installed on the bottom wall of each of the two positioning plates. Both the first and second anti-slip pads are made of rubber.

[0011] Preferably, a PLC controller is fixedly installed on the outer wall of the workbench body, and the PLC controller is electrically connected to the first motor, the second motor and the third motor respectively.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as a bidirectional screw, a cylinder, and a first anti-slip pad, the bidirectional screw is driven to rotate by a first motor, thereby adjusting the distance between the two positioning frames. Combined with the positioning plate driven by the cylinder, it can adapt to the positioning needs of automotive parts of different specifications and shapes, with strong versatility. Furthermore, the first and second anti-slip pads made of rubber not only enhance the clamping friction and prevent the workpiece from sliding, but also avoid damage to the workpiece surface and ensure grinding accuracy.

[0014] 2. By setting up components such as a one-way screw, a stabilizer bar, and a moving block, the one-way screw is driven to rotate by a third motor. When the one-way screw rotates, it can drive the moving block and grinding device to rise and fall through cooperation with the stabilizer bar, which can quickly adapt to the grinding needs of different workpieces and improve work efficiency.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A grinding workbench for automotive parts with workpiece positioning function includes a workbench body 1. Multiple support legs 2 are used to fix shock-absorbing pads 3 to the bottom wall of the workbench body 1. A bidirectional screw 5 is rotatably mounted on the bottom wall of the workbench body 1 via a movable frame 4. A first motor 6 connected to the bidirectional screw 5 is fixedly mounted on the outer wall of the movable frame 4. A limit rod 7 is fixedly mounted inside the movable frame 4. Two movable sleeves 8 are threaded onto the outer wall of the bidirectional screw 5. The limit rod 7 slides through the two movable sleeves 8. Mounting plates 10 are fixedly mounted on the bottom walls of both movable sleeves 8 via a connecting mechanism. The connecting mechanism includes a connecting plate 9 fixedly mounted on the bottom wall of the movable sleeve 8. The end of the connecting plate 9 is fixedly connected to the outer wall of the mounting plate 10. The connecting plate 9 ensures a stable connection between the movable sleeve 8 and the mounting plate 10, allowing the movement of the movable sleeve 8 to be stably transmitted to the mounting plate 10 and subsequent positioning components, ensuring the reliability of positioning adjustment.

[0024] The inner walls of both mounting plates 10 are fixedly fitted with positioning frames 13 via rotating rods 11. A second motor 12 connected to one of the rotating rods 11 is fixedly fitted on the outer wall of one of the mounting plates 10. Cylinders 16 are fixedly fitted on the upper surfaces of both positioning frames 13 via mounting frames 15. Positioning plates 17 are fixedly fitted on the telescopic ends of both cylinders 16. First anti-slip pads 14 are fixedly fitted on the inner bottom walls of both positioning frames 13. Two second anti-slip pads 18 are fixedly fitted on the bottom walls of both positioning plates 17. Both the first anti-slip pads 14 and the second anti-slip pads 18 are made of rubber. The rubber anti-slip pads not only increase the friction with the workpiece and effectively prevent the workpiece from sliding during grinding, but also use their elasticity to avoid rigid damage to the workpiece surface and protect the quality of the workpiece.

[0025] A one-way screw 20 is rotatably mounted on the upper end face of the workbench body 1 via a lifting frame 19. A third motor 21 connected to the one-way screw 20 is fixedly mounted on the upper end face of the lifting frame 19. A moving block 23 is threadedly mounted on the outer wall of the one-way screw 20 via a stabilizing mechanism. The stabilizing mechanism includes a stabilizing rod 22 fixedly installed inside the lifting frame 19. The stabilizing rod 22 slides through the moving block 23, and the stabilizing rod 22 guides and limits the moving block 23, preventing it from shifting or shaking when moving with the one-way screw 20, thus ensuring the stability of the grinding device 25 during its lifting process. A grinding device 25 is fixedly installed on the outer wall of the moving block 23 via a connecting mechanism. The connecting mechanism includes a connecting rod 24 fixedly installed on the outer wall of the moving block 23. The end of the connecting rod 24 is fixedly connected to the upper end face of the grinding device 25. The connecting rod 24 provides stable support and connection for the grinding device 25, so that the movement of the moving block 23 can accurately drive the grinding device 25 and ensure the accuracy of the position adjustment of the grinding device 25. A PLC controller 26 is fixedly installed on the outer wall of the worktable body 1. The PLC controller 26 is electrically connected to the first motor 6, the second motor 12 and the third motor 21 respectively.

[0026] When using this utility model, the part to be processed is placed on the upper surface of two first anti-slip pads 14. The parameters are set by the PLC controller 26 on the outer wall of the workbench body 1, and the first motor 6 is started. The first motor 6 drives the bidirectional screw 5 to rotate in the moving frame 4. Due to the sliding limit of the limit rod 7 on the two moving sleeves 8, the two moving sleeves 8 move towards each other along the bidirectional screw 5. The mounting plate 10 is moved synchronously through the connecting plate 9, so that the two positioning frames 13 gradually approach the two sides of the part until they are in contact with the outer wall of the part, thus completing the initial horizontal positioning.

[0027] At this time, the PLC controller 26 starts the cylinder 16. The telescopic end of the cylinder 16 extends downward, pushing the positioning plate 17 to move down synchronously until the second anti-slip pad 18 is in close contact with the upper surface of the accessory. The first anti-slip pad 14 and the second anti-slip pad 18 made of rubber form an upper and lower clamping structure, which increases the friction with the accessory to prevent slippage, and avoids damage to the surface of the accessory by rigid clamping through its own elastic buffer, thus achieving a stable fixation of the accessory.

[0028] According to the grinding requirements of the parts, the second motor 12 is started by the PLC controller 26. The second motor 12 drives the rotating rod 11 to rotate, thereby causing the positioning frame 13 and the fixed parts to rotate synchronously. When the parts rotate to the optimal grinding angle, the second motor 12 is turned off to complete the angle adjustment. Then the third motor 21 is started. The third motor 21 drives the one-way screw 20 to rotate in the lifting frame 19. Under the guidance of the stabilizing rod 22, the moving block 23 moves up and down along the one-way screw 20. The grinding device 25 is adjusted to a suitable height through the connecting rod 24. After the grinding device 25 is started, the parts can be precisely ground.

[0029] During the grinding process, the shock-absorbing pads 3 at the bottom of the support leg 2 can absorb the vibration of the equipment and reduce the impact of vibration on the grinding accuracy. If the grinding position needs to be adjusted, the PLC controller 26 can control the operation of each motor in real time, flexibly adjust the spacing of the positioning frame 13, the angle of the accessory, and the height of the grinding device 25 to meet the grinding needs of different parts. After the operation is completed, the grinding device 25 is turned off, and the cylinder 16 is controlled by the PLC controller 26 to retract and reset, which drives the positioning plate 17 to move up and separate from the accessory. Then, the first motor 6 is started in reverse to separate the two positioning frames 13, and the processed accessory can be taken out.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
