Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, specifically a sheet metal welding positioning device. Background Technology

[0002] Sheet metal is characterized by its light weight, high strength, electrical conductivity (which can be used for electromagnetic shielding), low cost, and good mass production performance, and it has been widely used in electronics, communications, automotive, and medical device industries. When welding sheet metal, the parts to be welded need to be clamped to prevent movement and avoid affecting the weld quality.

[0003] For welding T-shaped sheet metal parts, the joints of the T-shaped sheet metal parts need to be fully welded. Existing sheet metal welding positioning devices completely fix the T-shaped sheet metal parts, requiring the welder to move to weld different T-shaped sheet metal parts. The welder needs to break the welding during movement, which reduces work efficiency and is inconvenient to use. Therefore, those skilled in the art have provided sheet metal welding positioning devices to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a sheet metal welding positioning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sheet metal welding positioning device includes a fixed frame, a horizontal plate moving device, and a vertical plate clamping device. The horizontal plate moving device is bolted to the base plate of the fixed frame. The horizontal plate moving device is equipped with two "L"-shaped first supports. Several horizontal plate sliding guide rollers are arranged between the first supports. Three sections of second supports are evenly welded to the sides of the two first supports. A downward pressure roller device is slidably connected to the top of the second supports. A spring is arranged between the downward pressure roller device and the second support. A drive motor is arranged on the outer side of the second support and connected to the horizontal plate sliding guide rollers. A first groove is welded to the top center of the fixed frame. A vertical plate clamping device is slidably connected in the first groove. A movable clamping device is slidably connected in the vertical plate clamping device. Vertical plate sliding guide rollers are symmetrically arranged on the vertical plate clamping device and the movable clamping device. A T-shaped sheet metal horizontal plate is arranged on the horizontal plate sliding guide roller of the horizontal plate moving device. A T-shaped sheet metal vertical plate is arranged between the vertical plate sliding guide rollers of the vertical plate clamping device.

[0007] As a further embodiment of this utility model: a second sliding groove is welded to one side below the top of the fixed frame, and a T-shaped connector is slidably connected in the second sliding groove. A vertical guide rod is provided at the bottom center of the T-shaped connector, and a connecting plate is slidably connected to the vertical guide rod. A sliding through hole is provided at the center of the connecting plate and is slidably connected to the guide rod. A bolt is threadedly connected to the side of the sliding through hole and is slidably connected to the bottom of the T-shaped connector. A grinding motor is bolted to one side of the bottom of the connecting plate, and a grinding wheel is provided at the output end of the grinding motor.

[0008] As a further embodiment of this utility model: both the first slide groove and the second slide groove are provided with T-shaped slide grooves inside, and T-shaped sliders are welded to the top center of the vertical plate clamping device and the top center of the T-shaped slider. The T-shaped slide groove and the T-shaped slider are slidably connected, and the top of both the first slide groove and the second slide groove are rotatably connected with horizontal telescopic bolts. The horizontal telescopic bolts and the T-shaped sliders are threadedly connected.

[0009] As a further embodiment of this utility model: an adjusting bolt is rotatably connected to the center of the back of the movable clamping device, the adjusting bolt is threadedly connected to the vertical plate clamping device, and two guide posts are symmetrically arranged on the back of the movable clamping device, the guide posts being slidably connected to the movable clamping device.

[0010] As a further improvement of this utility model: an "L"-shaped baffle is welded to the side of the connecting plate; two triangular reinforcing plates are welded between the top of the fixed frame and the vertical plate; and four support legs are welded to the bottom of the fixed frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the horizontal and vertical plates of the T-shaped sheet metal part are fixedly connected by welding points. The drive motor on the horizontal plate moving device rotates, which drives the horizontal plate sliding guide rollers located at three points on the first support to rotate, so that the horizontal plate of the T-shaped sheet metal part placed between the horizontal plate sliding guide rollers and the lower pressure roller device moves. During this process, the vertical plate of the T-shaped sheet metal part slides between the vertical plate clamping device, so that the T-shaped sheet metal part slides smoothly, which makes it easier for the welder to stand still and weld, thus improving work efficiency.

[0013] 2. In this utility model, by adjusting the horizontal telescopic bolt on the second slide groove, the position of the T-shaped connector is changed. In conjunction with adjusting the bolt on the connecting plate, the vertical position of the grinding motor on the connecting plate is changed, ensuring that the grinding wheel at the top of the grinding motor can fit against the welding position of the T-shaped sheet metal part, pre-grinding the welding position of the T-shaped sheet metal part, removing the oxide layer, and improving the welding quality.

A horizontal plate of the T-shaped sheet metal part 2 is arranged on the horizontal plate sliding guide roller 15 of the horizontal plate moving device 3. A vertical plate of the T-shaped sheet metal part 2 is arranged between the vertical plate sliding guide rollers 21 of the vertical plate clamping device 5. The horizontal plate sliding guide roller 15 is driven to rotate by the drive motor 10, thereby driving the T-shaped sheet metal part 2 to slide. The welder stands still and welds the moving T-shaped sheet metal part 2, saving physical strength, preventing interruption in the welding process, and improving work efficiency.

[0024] Among them, a second slide groove 6 is welded to one side of the top lower part of the fixed frame 1. A T-shaped connector 7 is slidably connected in the second slide groove 6. A vertical guide rod 25 is set at the bottom center of the T-shaped connector 7. A connecting plate 8 is slidably connected to the vertical guide rod 25. A sliding through hole 27 is set at the center of the connecting plate 8 and is slidably connected to the guide rod. A bolt is threadedly connected to the side of the sliding through hole 27 and is slidably connected to the bottom of the T-shaped connector 7. A grinding motor 9 is bolted to one side of the bottom of the connecting plate 8. A grinding wheel 26 is set at the output end of the grinding motor 9. The grinding wheel 26 is used to polish the welding position of the T-shaped sheet metal part 2 to remove the oxide layer and improve the welding quality.

[0025] The first slide 4 and the second slide 6 are both equipped with T-shaped slides 19. The top center of the vertical plate clamping device 5 and the T-shaped slider 20 are both welded with T-shaped sliders 20. The T-shaped slides 19 and the T-shaped sliders 20 are slidably connected. The top of the first slide 4 and the second slide 6 are rotatably connected with horizontal telescopic bolts 13. The horizontal telescopic bolts 13 and the T-shaped sliders 20 are threaded. Rotating the horizontal telescopic bolts 13 can change the position of the vertical plate clamping device 5 and the grinding motor 9. It is suitable for T-shaped sheet metal parts 2 with different vertical plate positions and is easy to adjust.

[0026] Among them, the back center of the movable clamping device 22 is rotatably connected to the adjusting bolt 24, and the adjusting bolt 24 is threadedly connected to the vertical plate clamping device 5. Two guide posts 23 are symmetrically arranged on the back of the movable clamping device 22. The guide posts 23 are slidably connected to the movable clamping device 22, which facilitates the adjustment of the distance between the movable clamping device 22 and the vertical plate clamping device 5, so as to stabilize the vertical plate clamping of the T-shaped sheet metal part 2 while allowing for smooth sliding.

[0027] Among them, an "L"-shaped baffle 28 is welded to the side of the connecting plate 8 to prevent the sparks caused by the grinding wheel 26 grinding the oxide layer from affecting the welding; two triangular reinforcing plates 12 are welded between the top of the fixed frame 1 and the vertical plate to prevent the top plate of the fixed frame 1 from deforming after long-term use; and four support legs 11 are welded to the bottom of the fixed frame 1.

[0028] The working principle of this utility model is as follows: Rotating the horizontal telescopic bolt 13 located on the first slide groove 4 changes the position of the vertical plate clamping device 5. The T-shaped sheet metal part 2, pre-welded by electric welding, is placed into the horizontal plate moving device 3 and the vertical plate clamping device 5, so that the horizontal plate of the T-shaped sheet metal part 2 is located between the horizontal plate sliding guide roller 15 and the downward pressing roller device 17, and the vertical plate of the T-shaped sheet metal part 2 is located within the vertical plate clamping device 5. The downward pressing roller device 17, under the action of the spring 18, always adheres to the T-shaped sheet metal part 2. Rotating the adjusting bolt 24 moves the movable clamping device 22 closer to the vertical plate clamping device 5, ensuring stable clamping and smooth sliding of the vertical plate of the T-shaped sheet metal part 2. Adjusting the horizontal telescopic bolt 13 on the second slide groove 6 changes the position of the T-shaped connecting piece 7, and coordinating with the adjustment of the bolt located on the connecting plate 8. The vertical position of the grinding motor 9 located on the connecting plate 8 is changed, and the connecting plate 8 is slidably connected to the vertical guide rod 25, so that the grinding wheel 26 at the top of the grinding motor 9 can fit against the welding position of the T-shaped sheet metal part 2. After the power is turned on, the drive motor 10 rotates, which drives the horizontal sliding guide roller 15 to rotate, so that the horizontal plate of the T-shaped sheet metal part 2, which is placed between the horizontal sliding guide roller 15 and the lower pressure roller device 17, moves. The vertical plate of the T-shaped sheet metal part 2 slides between the vertical plate clamping device 5, so that the T-shaped sheet metal part 2 slides smoothly. Before the welder welds, the grinding wheel 26 of the grinding motor 9 pre-grinds the welding position to remove the oxide layer and improve the welding quality. The welder is positioned between the second brackets 16 to weld the ground welding position without moving, which improves the welding efficiency.
