Description

Technical Field

[0001] This utility model relates to the field of automotive parts clamping technology, and in particular to an automatic clamping device for automotive parts processing. Background Technology

[0002] As the fundamental unit of automobile manufacturing, the processing precision and production efficiency of automotive parts directly affect the quality and production capacity of the entire vehicle. In today's rapidly developing automotive manufacturing industry, automated clamping devices are widely used in automotive parts processing. Through automated operation, they achieve precise positioning and clamping, significantly improving production efficiency and processing precision, effectively meeting the demands of the automotive industry for large-scale, high-quality production.

[0003] Existing automated clamping devices for automotive parts processing typically consist of a base, a clamping mechanism, and a control system. The base provides stable support for the entire device; the clamping mechanism clamps and secures the parts using hydraulic, pneumatic, or electric methods; and the control system is responsible for controlling the clamping force and the movement sequence to ensure the accuracy and stability of the clamping process.

[0004] However, existing devices still have significant problems. First, during the processing of automotive parts, cutting and grinding operations generate pollutants such as dust and harmful chemical gases. Existing automatic clamping devices lack effective protection and purification measures, and producers are easily harmed by long-term exposure to this environment. Second, when processing the back of parts, the lack of an automatic flipping function often requires manual operation, which not only reduces production efficiency but also poses a significant safety hazard because the parts are still hot after processing and manual flipping can easily cause burns. Therefore, an automatic clamping device for automotive parts processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic clamping device for automotive parts processing. It aims to improve the existing automatic clamping devices in the prior art, which do not take effective purification and protection measures for harmful gases generated during cutting and grinding, thus threatening the health of producers. The device also requires manual flipping of the processed high-temperature parts, which reduces production efficiency and easily leads to burns.

[0031] 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.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an automatic clamping device for processing automotive parts, comprising a housing 1, an electric push rod 14 fixedly connected inside the housing 1, a top plate 12 fixedly connected to the output end of the electric push rod 14, a pad 18 fixedly connected to the top of the top plate 12, an electric push rod 19 fixedly connected to the top of the pad 18, a push plate 20 fixedly connected to the output end of the electric push rod 19, a rack 21 fixedly connected to the front side of the push plate 20, a lifting platform 9 fixedly connected to the top of the top plate 12, a protective shell 10 fixedly connected to the right side of the lifting platform 9, a gear 15 fixedly connected to the left side of the outer side of the protective shell 10, the gear 15 meshing with the rack 21, a fixed shell 16 fixedly connected inside the protective shell 10, a motor 17 fixedly connected inside the fixed shell 16, a threaded rod 22 fixedly connected to the output end of the motor 17, a moving plate 23 threadedly connected to the outer side of the threaded rod 22, two connecting rods 26 rotatably connected to the front and rear sides of the moving plate 23, and adjacent connecting rods 26... A clamp 24 is rotatably connected to the protective shell 10. Two connecting rods 25 are rotatably connected inside the protective shell 10. When processing the parts, the motor 17 drives the threaded rod 22 to rotate. The rotation of the threaded rod 22 can drive the moving plate 23 on its outer wall to move back and forth through the thread characteristics. At the same time, the moving plate 23 moves back and forth. The connecting rod 26 is rotatably connected to the moving plate 23, and the connecting rod 25 is rotatably connected to the connecting rod 26. As the moving plate 23 moves, the connecting rods 25 and 26 deform, thereby causing the clamp 24 to clamp or release the parts. After the clamped parts are processed, the electric push rod 14 pushes the top plate 12 to rise. After it rises, the electric push rod 19 pushes the rack 21 to slide, and the rack 21 meshes with the gear 15. The gear 15 is fixedly connected to the fixed shell 16. As the rack 21 slides, it drives the gear 15 to rotate, realizing the flipping of the parts. Then the electric push rod 14 begins to retract to process the back of the parts.

[0033] Reference Figure 1 and Figure 2A gas collection box 7 is slidably connected to the rear side of the protective shell 10. A fan 11 is fixedly connected to the inside of the gas collection box 7. An exhaust pipe 6 is fixedly connected to the right side of the gas collection box 7. Activated carbon 3 is fixedly connected inside the exhaust pipe 6. When the parts are processed, a large amount of harmful gas is generated. Producers who are exposed to this environment for a long time will suffer a lot of harm to their health. The harmful gas in the production process is extracted by the fan 11. The harmful gas is drawn into the exhaust pipe 6, and activated carbon 3 is fixedly connected in the exhaust pipe 6 to purify the harmful gas before it is discharged into the air.

[0034] Reference Figure 1 A pad 2 is fixedly connected to the top right side of the outer casing 1. The parts to be processed are placed on the pad 2, and then the device is started, and the clamp 24 is used to clamp the parts on the pad 2 for processing.

[0035] Reference Figure 1 and Figure 3 One end of connecting rod 25 away from the protective shell 10 is rotatably connected to the middle of connecting rod 26. Motor 17 drives threaded rod 22 to rotate, and threaded rod 22 connected to it will start to reciprocate. While moving plate 23 reciprocates, it causes connecting rod 25 and connecting rod 26 to deform, thereby clamping or releasing the item.

[0036] Reference Figure 1 The outer wall of the lifting platform 9 is slidably connected to the left side of the air collection box 7. The bottom of the air collection box 7 is fixedly connected to the top of the outer shell 1. The lifting platform 9 is pushed up by the electric push rod 14, and then driven by the gear 15 and the rack 21 to rotate the protective shell 10 and the clamp 24, thereby realizing the rotation function of the clamping device.

[0037] Reference Figure 1 , Figure 3 and Figure 4 A protective shell 13 is fixedly connected to the top of the top plate 12. The rack 21 is slidably connected inside the protective shell 13. This mechanism enables the device to flip. The push plate 20 is moved by the electric push rod 29, which in turn pushes the rack 21 to slide along the protective shell 13. The gear 15 is fixed on the fixed shell 16. So when the rack 21 moves, it drives the gear 15 to rotate. The rotation of the gear 15 drives the protective shell 10 to rotate, thus realizing the function of flipping the clamping device.

[0038] Reference Figure 1 and Figure 3 The top of the outer shell 1 is fixedly connected to a support column 4, the top of the support column 4 is fixedly connected to a ceiling 5, and the bottom left side of the ceiling 5 is fixedly connected to four support columns 8. The support column 4 and the four support columns 8 work together to fix the ceiling 5, and the support columns 8 fix the direction of movement of the lifting platform 9, so that it can only move up and down.

[0039] Reference Figure 1 , Figure 3 and Figure 4 The inner wall of the lifting platform 9 is slidably connected between the outer walls of the four support columns 2 8. The support columns 2 8 fix the movement trajectory of the lifting platform 9 and prevent it from tipping over during the lifting process, thus avoiding a production accident.

[0040] Working Principle: In the automotive parts processing, the automatic clamping device is driven by motor 17. When motor 17 operates, it drives the threaded rod 22 to rotate. Since the threaded rod 22 only has rotational freedom and no axial movement capability, the moving plate 23, which is threaded to it, achieves reciprocating linear motion under the action of helical transmission. At the same time, the connecting rod 26, which is rotatably connected, moves in coordination with the moving plate 23. Its hinge structure with the connecting rod 25 causes the angle between the two rods to change, thereby controlling the clamping and releasing action of the fixture 24 to complete the clamping and releasing action of the parts. After the parts have completed single-sided processing, the device starts the flipping process. First, the electric push rod 14 extends, pushing the top plate 12 to rise, so that the clamped parts are removed from the processing table. Then, the electric push rod 29 drives the rack 21 to slide along the slide rail. Since the rack 21 is meshed with the gear 15 and the gear 15 is fixedly connected to the fixed shell 16, the linear motion of the rack 21 is converted into the rotational motion of the gear 15, which drives the fixed shell 16 and the clamped parts to flip. Once the parts are flipped into position, the electric push rod 14 retracts and resets, lowering the parts to the processing station for back-side processing. The device is equipped with a purification system to address harmful gases generated during processing. Fan 11 generates negative pressure suction, drawing harmful gases from the processing area into the extraction pipe 6. Activated carbon 3, fixedly installed inside the pipe, filters and purifies the harmful substances in the exhaust gas through physical adsorption, ensuring that the emitted gases meet safety standards and effectively reducing occupational health risks in the production environment.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
