Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a sheet metal welding fixture. Background Technology

[0002] Sheet metal processing is a comprehensive cold processing technology for thin metal sheets (usually below 6nm), including shearing, punching, bending, welding, riveting, etc. Its significant feature is that the thickness of the same part is consistent.

[0003] In sheet metal processing, welding is a crucial step in assembling sheet metal parts. The precision and efficiency of welding heavily depend on the positioning and securing effect of the fixture on the sheet metal parts. Currently, most sheet metal welding fixtures on the market adopt a fixed structure design, meaning the fixture body and the mounting base are integrated, which cannot flexibly adjust the posture of the sheet metal parts according to changes in the welding position, resulting in poor flexibility.

[0026] like Figures 1-3 As shown, an optional embodiment of this utility model provides a sheet metal welding fixture, characterized in that it includes:

[0027] Mounting base 1, wherein a pivot hole 10 is provided on the mounting base 1;

[0028] A clamp body 3 for clamping sheet metal parts, wherein a pivot 31 extends outward from the center of the bottom end face of the clamp body 3, and the clamp body 3 is pivotally connected to the pivot hole 10 of the mounting base 1 via the pivot 31; the clamp body 3 is also fixed to the mounting base 1 by an adjusting positioning structure 32; and

[0029] A plurality of movable support components 5, each of the movable support components 5 including a support foot 51 pivotally connected at its top to the bottom surface of the mounting base 1, a ball head 52 disposed on the free end of the support foot 51, and a ball seat 53 for the ball head 52 to be movably fitted therein, the ball seat 53 being fixed to the table surface of the external workbench 6.

[0030] In this embodiment of the invention, the fixture body 3 is rotatably connected to the mounting base 1 via a pivot hole 10 on a rotating shaft 31. With the assistance of an adjustable positioning structure 32, the operator can flexibly rotate the fixture body 3 to the required angle and then fix it according to the welding needs of the sheet metal part. Furthermore, by adding a movable support component 5, the ball joint 52 and ball seat 53 in the movable support component 5 cooperate to allow the mounting base 1 to adjust its angle according to welding requirements. This allows for welding operations at different angles and enables rapid adjustment of the workpiece posture for multi-faceted welding of the same sheet metal part, demonstrating good applicability. In specific implementation, two sets of sheet metal welding fixtures can be set up, with each set holding one sheet metal part for welding operations.

[0031] In one optional embodiment of this utility model, such as Figures 1-3 As shown, the adjustment and positioning structure 32 includes an annular groove 321 disposed on the mounting base 1, a positioning hole 33 with one end passing through a correspondingly opened positioning hole 33 on the side end of the clamp body 3, a positioning rod 322 that performs limited movement within the annular groove 321, and a fastening cap 323 screwed onto the positioning rod 322. In this embodiment, by correspondingly providing the above-mentioned adjustment and positioning structure 32 on the mounting base 1 and the clamp body 3, and by threading the fastening cap 323 to the positioning rod 322, when the clamp is adjusted to the target angle, tightening the fastening cap 323 can lock the positioning rod 322 to the clamp body 3 and the mounting base 1, thereby preventing the clamp body 3 from rotating.

[0032] In one optional embodiment of this utility model, such as Figures 1-3 As shown, there are two annular grooves 321, two positioning rods 322, and two fastening caps 323. The two annular grooves 321 are symmetrically distributed on both sides of the pivot hole 10. The two sides of the clamp body 3 protrude outward to form lugs 34, and the lugs 34 are provided with the positioning holes 33. In this embodiment, there are two annular grooves 321, two positioning rods 322, and two fastening caps 323. The two annular grooves 321 are symmetrically distributed on both sides of the pivot hole 10 with the pivot hole 10 on the mounting base 1 as the center. The positioning holes 33 are opened on the lugs 34 integrally formed on both sides of the clamp body 3, which can effectively improve the stability of the adjustment and positioning.

[0033] In one optional embodiment of this utility model, such as Figures 1-3As shown, the outer contour of the mounting base 1 is circular, and a scale mark 11 for indicating the rotation angle of the fixture body 3 is provided on the outer surface of the mounting base 1. In this embodiment, by setting the outer contour of the mounting base 1 to be circular and providing a scale mark 11 near the edge of its outer surface, the operator can easily observe the rotation position of the fixture body 3 during the adjustment process, thus meeting the needs of different welding angles.

[0034] In one optional embodiment of this utility model, such as Figures 1-3 As shown, a rotating rod 12 is provided on the side wall of the mounting base 1. In this embodiment, by providing a rotating rod 12 on the side wall of the mounting base 1, the operator can drive the mounting base 1 to rotate around the mating point of the ball head 52 and the ball seat 53 by holding the rotating rod 12, thereby reducing the difficulty of angle adjustment.

[0035] In one optional embodiment of this utility model, such as Figures 1-3 As shown, the clamp body 3 includes a base 35 assembled on the mounting base 1, a fixed clamping arm 36 located at one end of the base 35, a movable clamping arm 37 disposed opposite to the fixed clamping arm 36, an adjusting rod 38 with one end pivotally connected to the movable clamping arm 37 and the other end screwed to a corresponding screw hole in the fixed clamping arm 36, and a handle 39 mounted on the adjusting rod 38. The base 35 is provided with the rotating shaft 31. In this embodiment, by setting the above-mentioned clamp, the operator can rotate the handle 39, causing the adjusting rod 38 to rotate, so that the movable clamping arm 37 will move linearly along the axial direction of the adjusting rod 38. When the movable clamping arm 37 moves towards the fixed clamping arm 36, the size of the clamping space is adjusted to adapt to the clamping requirements of sheet metal parts of different thicknesses.

[0036] In one optional embodiment of this utility model, such as Figure 1 As shown, a guide rod 361 is fixed on the fixed clamping arm 36, and the movable clamping arm 37 is movably connected to the guide rod 361. In this embodiment, by fixing the guide rod 361 on the fixed clamping arm 36 and connecting the guide rod 361 to the guide hole in the movable clamping arm 37, the movable clamping arm 37 can only move along the axial direction of the guide rod 361, thereby further improving the clamping accuracy.

[0037] In one optional embodiment of this utility model, such as Figure 1 As shown, the clamping surfaces of the fixed clamping arm 36 and the movable clamping arm 37 that are opposite each other and in contact with the sheet metal part are provided with anti-slip textures 30. In this embodiment, by providing anti-slip textures 30 on the clamping surfaces of the fixed clamping arm 36 and the movable clamping arm 37 that are opposite each other and in contact with the sheet metal part, the friction between the clamping surfaces and the sheet metal part can be increased, ensuring that the sheet metal part remains stable throughout the welding process.

[0038] In one optional embodiment of this utility model, such as Figure 2 As shown, the number of movable support components 5 is at least three. In this embodiment, the number of movable support components 5 is set to at least three. The support structure at three or more points ensures the overall stability of the mounting base 1 and the clamp body 3.
