Description

Technical Field

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

[0002] Automotive welding overturning equipment is a type of mechanical equipment used in the automotive manufacturing process, especially during body welding, to fix and flip the car body or its components. Its main function is to keep the workpiece (such as the chassis, body panels, etc.) stable during welding operations and to flip the workpiece to different angles or positions as needed, making it easier for workers to access the welding points, thereby improving welding efficiency and quality. Automotive welding overturning equipment is an indispensable part of modern automotive manufacturing plants, playing a vital role in improving production efficiency, enhancing product quality, and ensuring worker safety.

[0003] Existing automotive welding flipping equipment's fixtures and support structures may cause indentations, scratches, or other forms of damage to the workpiece surface when fixing it, especially when processing body parts with high appearance requirements. Furthermore, flipping equipment is usually designed to fit workpieces of specific sizes and shapes. When encountering different models or non-standard workpieces, additional adjustments or even replacements of the fixtures are required, which increases production preparation time and costs. Therefore, we propose an automotive welding flipping equipment to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose an automobile welding and turning device.

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

[0006] An automotive welding flipping device includes a flipping mechanism and a clamping mechanism. The clamping mechanism includes several support plates. Multiple suction cups are fixedly installed on one side of each support plate. A rotating hole is opened on one side of each support plate. The same rotating shaft is rotatably installed in the multiple rotating holes. A lead screw is fixedly installed at both ends of the rotating shaft. A movable plate is threaded onto the outer side of the lead screw. A clamping plate is fixedly installed at the bottom of the movable plate.

[0007] Furthermore, the flipping mechanism includes two support frames, a rotating motor is fixedly installed on one side of the support frame, and the same flipping frame is fixedly installed between the output shafts of the two rotating motors. Connecting plates are fixedly connected to both sides of the support plate, and one side of the connecting plate is fixedly connected to the inner wall of the flipping frame.

[0008] Furthermore, several hydraulic rods are fixedly installed on both the left and right sides of the flipping frame, and a support plate is fixedly connected to the bottom of each hydraulic rod.

[0009] Furthermore, a servo motor is fixedly installed on the top of the support plate located in the middle, a drive gear is fixedly installed on the output shaft of the servo motor, and a driven gear is fixedly sleeved on the outside of the rotating shaft, with the drive gear meshing with the driven gear.

[0010] Furthermore, two guide plates are fixedly installed on one side of the support plate located on the front and rear sides, and the movable plate is slidably sleeved on the outside of the corresponding two guide plates.

[0011] Furthermore, an anti-slip plate is fixedly installed on one side of the clamping plate, and a wavy anti-slip groove is provided on one side of the anti-slip plate.

[0012] Furthermore, the two lead screws have opposite thread directions and the same thread pitch.

[0013] The beneficial effects of this utility model are as follows:

[0014] The workpiece on the pallet is lifted by a hydraulic rod until it comes into contact with the suction cup and is adsorbed. The suction cup can adsorb the workpiece and provide a more uniform pressure distribution, reducing damage to the workpiece surface and protecting the quality and appearance of the workpiece. In addition, the suction cup can adsorb workpieces of different weights and sizes, eliminating the need for frequent fixture changes and improving the flexibility and efficiency of the equipment.

[0020] 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.

[0021] Reference Figure 1-4 An automobile welding and turning device includes a turning mechanism and a clamping mechanism. The clamping mechanism includes several support plates 5. Multiple suction cups 6 are fixedly installed on one side of the support plates 5. A rotating hole is opened on one side of the support plates 5. The same rotating shaft 7 is rotatably installed in the multiple rotating holes. Lead screws 8 are fixedly installed at both ends of the rotating shaft 7. A movable plate 9 is threaded on the outside of the lead screw 8. A clamping plate 10 is fixedly installed at the bottom of the movable plate 9.

[0022] In this embodiment, the flipping mechanism includes two support frames 1. A rotary motor 2 is fixedly installed on one side of the support frame 1. The same flipping frame 3 is fixedly installed between the output shafts of the two rotary motors 2. Connecting plates 17 are fixedly connected to both sides of the support plate 5. One side of the connecting plate 17 is fixedly connected to the inner wall of the flipping frame 3. The flipping frame 3 is driven to rotate by the two rotary motors 2. The setting of two rotary motors 2 can achieve more precise and stable control and realize the flipping function of the workpiece. The rotary motors 2 are usually used in conjunction with a reducer.

[0023] In this embodiment, several hydraulic rods 4 are fixedly installed on both the left and right sides of the flipping frame 3, and a support plate 16 is fixedly connected to the bottom of the hydraulic rods 4.

[0024] In practical use, the workpiece is placed on multiple pallets 16, and multiple hydraulic rods 4 are activated simultaneously. The hydraulic rods 4 drive the multiple pallets 16 and the workpiece to move upward in sync until the top of the workpiece is squeezed against the suction cup 6 and is attracted by the suction cup 6.

[0025] It should be noted that traditional flipping equipment usually uses mechanical clamps or support structures to fix the workpiece. Using the suction cup 6 to adsorb the workpiece can provide a more uniform pressure distribution and reduce damage to the workpiece surface. The hydraulic rod 4 is used to lift the workpiece on the pallet 16 to contact the suction cup 6 and be adsorbed. This process can be pre-positioned without changing the workpiece posture, which helps to improve the accuracy of workpiece installation.

[0026] Furthermore, thanks to the use of the suction cup 6 and the adjustable hydraulic rod 4 system, this device can better adapt to workpieces of different shapes and sizes, expanding its application range. The suction cup 6 can reduce indentations or other forms of damage to the workpiece surface, making it particularly suitable for handling body parts with high appearance requirements. Moreover, if there is a problem with the suction cup 6 or the hydraulic rod 4, it is relatively easy to replace or repair without affecting the overall frame structure.

[0027] In this embodiment, a servo motor 11 is fixedly installed on the top of the support plate 5 located in the middle, a drive gear 12 is fixedly installed on the output shaft of the servo motor 11, and a driven gear 13 is fixedly sleeved on the outer side of the rotating shaft 7. The drive gear 12 and the driven gear 13 mesh with each other.

[0028] In this embodiment, two guide plates 14 are fixedly installed on one side of the support plate 5 located on the front and rear sides, and the movable plate 9 is slidably sleeved on the outside of the corresponding two guide plates 14.

[0029] In this embodiment, an anti-slip plate 15 is fixedly installed on one side of the clamping plate 10. A wave-shaped anti-slip groove is provided on one side of the anti-slip plate 15. The anti-slip plate 15 is made of an elastic material such as rubber, which improves the stability of the clamping plate 10 in clamping the workpiece and protects the workpiece.

[0030] In this embodiment, the two lead screws 8 have opposite thread directions and the same thread pitch.

[0031] In practical use, after the workpiece is attracted by multiple suction cups 6, the output shaft of the servo motor 11 drives the rotating shaft 7 to rotate through the cooperation of the drive gear 12 and the driven gear 13, thereby driving the two lead screws 8 to rotate, thereby driving the two moving plates 9 to move towards each other, thereby driving the clamping plate 10 to clamp the workpiece, further preventing the workpiece from slipping. Then, the two rotating motors 2 are started. Under the action of the reducer, the rotating motors 2 rotate slowly and evenly to prevent the workpiece from slipping due to vibration caused by excessive speed and instability.

[0032] 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.
