Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a welding and fixing device for cylindrical sheet metal parts. Background Technology

[0002] Sheet metal parts are parts made from metal sheets and are widely used in industries such as automobiles, aerospace, and home appliances. Cylindrical sheet metal parts are a common type of sheet metal part. During the processing, welding operations are usually required, such as welding the ends of the cylindrical body or welding at the joints.

[0003] In traditional cylindrical sheet metal welding, workers typically use manual methods or basic welding fixtures to fix the sheet metal parts. Because the surface of cylindrical sheet metal parts is a relatively smooth arc shape, the contact area between conventional rectangular clamps and the cylindrical sheet metal surface is small, making it easy for the sheet metal parts to shift during welding, which in turn affects the welding quality. At the same time, the fixing devices are often designed for sheet metal parts of a specific size, which has poor versatility and makes it difficult to quickly adapt to sheet metal parts of different diameters and lengths. Therefore, a cylindrical sheet metal welding fixing device is proposed to solve the problems mentioned above. Utility Model Content

[0004] To solve the above-mentioned technical problems, a welding and fixing device for cylindrical sheet metal parts is provided. This technical solution addresses the issue mentioned in the background art, where workers typically use manual methods or basic welding fixtures to fix the sheet metal parts during traditional welding of cylindrical sheet metal parts. Because the surface of the cylindrical sheet metal parts is a relatively smooth arc shape, the contact area between the conventional rectangular clamp and the cylindrical sheet metal surface is small, making it easy for the sheet metal parts to shift during welding, thus affecting the welding quality. At the same time, the fixing device is often designed for sheet metal parts of a specific size, resulting in poor versatility and difficulty in quickly adapting to sheet metal parts of different diameters and lengths.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cylindrical sheet metal welding and fixing device includes a placement platform. Four evenly distributed electric push rods are fixedly installed on the inner bottom of the placement platform. A lifting seat is fixedly connected to the output end of each electric push rod. Four evenly distributed sliding grooves are formed at the upper end of the lifting seat. A lead screw is rotatably connected inside each sliding groove. One end of the lead screw passes through the outer side of the lifting seat and is fixedly connected to a driven gear. An arc-shaped clamp is threaded onto the outer surface of the lead screw. A rubber pad is fixedly connected to the inner side of the arc-shaped clamp. A drive chamber is provided inside the lifting seat. A motor is fixedly installed at the lower end of the lifting seat. The output end of the motor passes through the lower end of the drive chamber and is fixedly connected to a first bevel gear. Four evenly distributed second bevel gears mesh around the periphery of the first bevel gear. A rotating shaft is fixedly connected to the end of each second bevel gear. The other end of the rotating shaft passes through the inner wall of the drive chamber and is fixedly connected to a driving gear.

[0007] Preferably, the driving gear and the driven gear mesh with each other.

[0008] Preferably, a through groove is provided at the upper end of the placement platform and at the corresponding position of the slide groove, and the upper end of the arc-shaped clamp plate passes through the through groove and extends to the upper end of the placement platform.

[0009] Preferably, the upper end of the placement platform is fixedly connected to a positioning post on the inner side of the four through slots.

[0010] Preferably, the drive cavity is fixedly connected to four evenly distributed fixing plates, and the rotating shaft is rotatably connected to the inner side of the fixing plates.

[0011] Preferably, four evenly distributed guide rods are fixedly connected between the top and bottom of the inner side of the placement platform.

[0012] Preferably, two symmetrically distributed guide blocks are fixedly connected to both the left and right sides of the lifting seat, and the guide blocks are slidably connected to the outer surface of the guide rod.

[0013] The advantages of this utility model compared with the prior art are:

[0014] This solution proposes a welding and fixing device for cylindrical sheet metal parts. By setting up arc-shaped clamping plates to clamp and fix the cylindrical sheet metal parts, it can match the outer surface of the cylindrical sheet metal parts well, providing a larger contact area, thereby enhancing the clamping force and ensuring that the sheet metal parts will not shift or loosen during the welding process. At the same time, the spacing of the arc-shaped clamping plates can be adjusted by rotating the screw, which can accommodate cylindrical sheet metal parts of various diameters. The height of the arc-shaped clamping plates can be adjusted by raising or lowering the lifting seat through an electric push rod, which can accommodate cylindrical sheet metal parts of different lengths. This avoids the limitations caused by the single-size design of traditional clamps and has greater versatility. Attached Figure Description

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figures 1-5 As shown, a cylindrical sheet metal welding and fixing device includes a placement platform 1. Four evenly distributed electric push rods 2 are fixedly installed on the inner bottom end of the placement platform 1. A lifting seat 3 is fixedly connected to the output end of each electric push rod 2. Four evenly distributed sliding grooves 4 are opened on the upper end of the lifting seat 3. A lead screw 5 is rotatably connected inside the sliding grooves 4. One end of the lead screw 5 passes through the outer side of the lifting seat 3 and is fixedly connected to a driven gear 6. An arc-shaped clamping plate 7 is threaded onto the outer surface of the lead screw 5. The inner side of the arc-shaped clamping plate 7 is fixedly connected to... There is a rubber pad 8. The inside of the lifting seat 3 is provided with a drive cavity 19. The lower end of the lifting seat 3 is fixedly installed with a motor 9. The output end of the motor 9 passes through the lower end of the drive cavity 19 and is fixedly connected to a first bevel gear 10. Four evenly distributed second bevel gears 11 mesh around the periphery of the first bevel gear 10. The end of the second bevel gear 11 is fixedly connected to a rotating shaft 12. The other end of the rotating shaft 12 passes through the inner wall of the drive cavity 19 and is fixedly connected to a driving gear 13. The driving gear 13 meshes with the driven gear 6.

[0024] Furthermore, a through groove 15 is provided at the corresponding position of the upper end of the placement platform 1 and the slide 4, and the upper end of the arc-shaped clamp 7 passes through the through groove 15 and extends to the upper end of the placement platform 1.

[0025] Furthermore, the threads of the four lead screws 5 are in the same direction. The first bevel gear 10 is driven by the motor 9 to rotate, which in turn drives the four second bevel gears 11 to rotate. Under the transmission action of the rotating shaft 12 and the driving gear 13, the four driven gears 6 drive the four lead screws 5 to rotate synchronously, thereby causing the four arc-shaped clamping plates 7 to move closer or further apart. By adjusting the distance between the four arc-shaped clamping plates 7, cylindrical sheet metal parts of different diameters can be clamped and fixed.

[0026] Furthermore, by using the electric push rod 2 to move the lifting seat 3 up and down, the four arc-shaped clamping plates 7 can be moved up and down, thereby adjusting the height of the arc-shaped clamping plates 7 relative to the upper end of the placement platform 1, which can clamp and fix cylindrical sheet metal parts of different lengths.

[0027] Furthermore, the upper end of the placement platform 1 is fixedly connected to the inner side of the four through slots 15 with positioning posts 16. When placing the cylindrical sheet metal parts, the cylindrical sheet metal parts can be initially positioned by fitting them onto the outer surface of the positioning posts 16.

[0028] Furthermore, four evenly distributed fixing plates 14 are fixedly connected inside the drive cavity 19, and the rotating shaft 12 is rotatably connected to the inner side of the fixing plates 14. The fixing plates 14 can provide auxiliary support for the rotating shaft 12.

[0029] Furthermore, four evenly distributed guide rods 17 are fixedly connected between the top and bottom of the inner side of the placement platform 1, and two symmetrically distributed guide blocks 18 are fixedly connected to both the left and right sides of the lifting seat 3. The guide blocks 18 are slidably connected to the outer surface of the guide rods 17. The guide blocks 18 and the guide rods 17 guide the vertical movement of the lifting seat 3, making it move more smoothly.

[0030] Working principle: When in use, first, the cylindrical sheet metal part is placed on the outer surface of the positioning post 16. Then, the electric push rod 2 is started to drive the lifting seat 3 to move in the vertical direction, adjusting the arc-shaped clamping plate 7 to a height that matches the cylindrical sheet metal part. Next, the motor 9 is started to drive the first bevel gear 10 to rotate. Under the transmission action of the rotating shaft 12, the driving gear 13 and the driven gear 6, the four lead screws 5 rotate simultaneously, thereby driving the four arc-shaped clamping plates 7 to clamp and fix the cylindrical sheet metal part.
