Description

Technical Field

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

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming. Its significant characteristic is that the thickness of the same part is consistent. Products processed by sheet metal processing are called sheet metal parts. The sheet metal parts referred to in different industries are generally different. Sheet metal parts need to be clamped and fixed when welding.

[0003] Existing technologies, such as CN218461317U, describe a sheet metal assembly and welding device. Sheet metal parts clamped on the surfaces of a fixed plate and a movable plate are assembled by interlocking. Then, by tightening a nut along the screw towards one side of the movable plate, the fixed plate and the movable plate are fixed together, thereby fixing the position of the sheet metal parts and facilitating subsequent processing operations.

[0004] However, this device still has some shortcomings in its use:

[0005] 1. This device cannot quickly clamp sheet metal parts of different sizes. It is necessary to adjust the nuts to fix the movable plate, which reduces work efficiency. When the fixture is used to fix the sheet metal parts in the air, the sheet metal parts are prone to deformation during processing.

[0006] 2. After the device fixes the sheet metal parts, it makes it inconvenient to adjust the processing angle. If the angle needs to be changed, the sheet metal parts must be fixed again, which reduces the practicality of the device. Utility Model Content

When the fixture fixes the sheet metal parts in the air, the sheet metal parts are prone to deformation during processing. After the device fixes the sheet metal parts, it makes it inconvenient to adjust the processing angle. If the angle needs to be changed, the sheet metal parts must be re-fixed, which reduces the practicality of the device.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

The fixing plate 201 is L-shaped, and the limiting plate 207 is located on the fixing plate 201. At the top of the positioning block 204, a fixing sleeve 205 is provided on the top of the fixing sleeve 205, and a fixing bolt 206 is provided on the top of the fixing sleeve 205. The fixing bolt 206 passes through the fixing sleeve 205 and extends into the support plate 1. The fixing bolt 206 is threadedly connected to the fixing sleeve 205. A sliding groove 202 is provided on the top of the fixing plate 201. A moving block 208 is fixedly connected to the bottom of the limiting plate 207.

The anti-slip pad 211 is made of rubber. Two fixing bolts 206 are provided, and the two fixing bolts 206 are located on both sides of the positioning block 204.

[0029] The adjusting rod 203 can limit the limiting plate 207 toward the fixing plate 201, thereby enabling the quick fixing of sheet metal parts of different sizes.

[0030] According to this embodiment Figure 1 , Figure 3 and Figure 4 As shown, the adjustment assembly 3 includes a mounting hole 305 on the top of the support plate 1, a mounting platform 4 extending into the mounting hole 305 and rotatably connected to the mounting hole 305, a mounting groove 302 on the bottom of the support plate 1, a drive motor 303 installed in the mounting groove 302, an adjustment gear 304 fixedly connected to the output end of the drive motor 303, a gear ring 301 fixedly connected to the outer surface of the mounting platform 4, the gear ring 301 meshing with the adjustment gear 304, connecting posts 209 fixedly connected to the top and bottom of the positioning block 204 respectively, the two connecting posts 209 being inserted into the support plate 1 and the fixing sleeve 205 respectively, and a support leg 5 fixedly connected to the bottom of the support plate 1, the support leg 5 being L-shaped.
