DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1

[0035] See also Figure 1-Figure 8 The present invention provides a technical solution: a sheet metal welding tool, including a workbench 1, on which two support seats 2 are movably arranged, the two support seats 2 are arranged at angles to each other, and the two support seats 2 both penetrate the workbench 1; two clamping assemblies 3 are arranged on the workbench 1, and the two support seats 2 correspond to one clamping assembly 3 respectively; a guide limit assembly 4 and two drive assemblies 6 are also arranged on the workbench 1, the guide limit assembly 4 is rotatably arranged on the workbench 1, and the two drive assemblies 6 are respectively used to drive the two support seats 2 to move up and down; each support seat 2 is respectively provided with a pressing assembly 5, and the two pressing assemblies 5 correspond to the positions of the two clamping assemblies 3 respectively.

[0036] The clamping assembly 3 includes a carrier plate 31 arranged on the workbench 1, on which an elastic spiral rod 36 is fixedly arranged, and the elastic spiral rod 36 corresponds to the central area of ​​the carrier plate 31; on the carrier plate 31, a plurality of butterfly elastic rings 32 are neatly stacked in sequence, except for the bottom butterfly elastic ring 32 and the top butterfly elastic ring 32, each of the remaining butterfly elastic rings 32 is respectively sleeved with an elastic clamping ring 33, and the elastic clamping ring 33 is used to clamp the sheet metal workpiece to be welded (hereinafter referred to as the workpiece); specifically, at the top An annular embedding groove 321 is coaxially arranged on each butterfly elastic ring 32 between the uppermost butterfly elastic ring 32 and the lowermost butterfly elastic ring 32, one end of the elastic clamping ring 33 is matched with the annular embedding groove 321, and the end of the elastic clamping ring 33 is fixed in the annular embedding groove 321; at the same time, when the elastic clamping ring 33 does not clamp the workpiece, the butterfly elastic ring 32 is coaxial with the elastic clamping ring 33 outside it; the butterfly elastic ring 32 is made of metal material with good elasticity, such as copper; the elastic clamping ring 33 can be made of rubber, silicone and other materials.

[0037] A support column 37 is provided at the center of the top of the carrier plate 31. The support column 37 is coaxial with the carrier plate 31 and passes through each butterfly elastic ring 32. At the same time, all the butterfly elastic rings 32 are sleeved on the outside of the elastic spiral rod 36. In the normal state of the elastic spiral rod 36, the elastic spiral rod 36 is adapted to the inner ring surface of the butterfly elastic ring 32. Through the cooperation between the elastic spiral rod 36 and the butterfly elastic ring 32, it is convenient to limit the butterfly elastic ring 32, such as Figure 4 As shown, the limited butterfly-shaped elastic ring 32 is coaxial with the support column 37; the elastic spiral rod 36 is made of metal material with good elasticity.

[0038] The clamping assembly 3 also includes a pressing ring 34, which is movably arranged on the supporting column 37, and the pressing ring 34 is coaxial with the supporting column 37; specifically, two slide grooves 371 are arranged on the supporting column 37, and the two slide grooves 371 are arranged along the axis direction of the supporting column 37; two limiting sliders 341 are fixedly arranged on the inner ring surface of the pressing ring 34, and the two limiting sliders 341 are respectively arranged in the two slide grooves 371; through the cooperation between the limiting sliders 341 and the slide grooves 371, the pressing ring 34 can be moved up and down; a retaining ring 38 is detachably arranged on the top of the supporting column 37, and the retaining ring 38 is used to prevent the pressing ring 34 from moving out of the top of the supporting column 37; a pressing cylinder 35 is arranged at the bottom of the pressing ring 34, and the pressing cylinder 35 is coaxial with the pressing ring 34; in addition, a plane for contacting the bottom end of the pressing cylinder 35 is arranged at the top of the uppermost butterfly elastic ring 32, and the inner ring surface diameter of the pressing cylinder 35 is slightly larger than the inner ring surface diameter of the butterfly elastic ring 32.

[0039] The guide limit assembly 4 adopts a clamping roller 41, which is movably connected to the workbench 1 through a bearing; the clamping roller 41 is vertically arranged, and a support ring 42 is arranged at the bottom end of the clamping roller 41, and the support ring 42 is coaxial with the clamping roller 41, and the support ring 42 is used to support the workpiece.

[0040] The pressing assembly 5 includes a fixed head 51 arranged on the support seat 2, and a pressure head 52 is fixedly arranged on the fixed head 51, and the pressure head 52 is used to press down the pressure ring 34; the pressure head 52 is an integral cylindrical structure, the pressure head 52 is coaxial with the pressure ring 34 included in the corresponding clamping assembly 3, and the pressure head 52 is located above the pressure ring 34.

[0041] In the present embodiment, by driving the support seat 2 with the driving assembly 6 to move downward, the pressure head 52 can be driven to press the pressure ring 34, thereby causing the pressure cylinder 35 to press down the uppermost butterfly elastic ring 32, causing the multiple butterfly elastic rings 32 arranged in a stacked manner to deform, so that each butterfly elastic ring 32 expands outward. Since the multiple butterfly elastic rings 32 have the same structure and are neatly stacked, the outward expansion state is basically consistent, and since the uppermost butterfly elastic ring 32 is uniformly stressed, each part of the butterfly elastic ring 32 expands outward basically uniformly, further causing the elastic clamping ring 33 to deform and the outer diameter to increase; when the butterfly elastic ring 32 is deformed, the elastic spiral rod 36 will also be deformed. When the pressure head 52 moves upward to release the pressure on the pressure ring 34, the resetting of the elastic spiral rod 36 facilitates the rapid resetting of the butterfly elastic ring 32.

[0042] The welding fixture can be used to clamp workpieces with arc structures, such as Fig. 9As shown in the figure, the arc portion of the workpiece is clamped between the two clamping assemblies 3, and the arc portion of the workpiece is covered on the outside of multiple butterfly elastic rings 32 adjacent to the clamping roller 41; at the same time, the workpiece is also located between the clamping roller 41 and the multiple butterfly elastic rings 32 adjacent to the clamping roller 41, and the support ring 42 at the bottom end of the clamping roller 41 is used to support the workpiece; when the arc portion of the workpiece can be coaxial with the butterfly elastic ring 32 covered by it (the thickness of the workpiece can be different within a certain range), the butterfly elastic ring 32 covered by the arc portion of the workpiece is deformed, and because the elastic clamping ring 33 can be deformed, the corresponding elastic clamping ring 33 can be well adapted to the arc portion of the workpiece, which effectively improves the clamping effect; if the arc portion of the workpiece cannot be coaxial with the butterfly elastic ring 32 covered by it, that is, Fig.10 As shown, the workpiece can also be clamped and fixed, which is suitable for occasions where the requirements for workpiece clamping stability are not high.

[0043] In addition, it can also be used to clamp flat workpieces, such as Fig.11 The workpiece is placed in the manner shown, and the workpiece is supported by the support ring 42. At this time, through the deformation of the butterfly elastic ring 32, the elastic clamping ring 33 can clamp both sides of the workpiece, thereby meeting different usage requirements and improving the adaptability of the entire welding tooling.

[0044] Furthermore, in the present embodiment, the pressing ring 34 is pressed down by the pressing head 52, thereby causing the pressing cylinder 35 to press down the uppermost butterfly-shaped elastic ring 32, further causing the multiple butterfly-shaped elastic rings 32 stacked in a stack to deform, thereby achieving a clamping effect; that is, clamping can be achieved by simply pressing down, and the operation is simple and efficient.

[0046] See again Figure 1-Figure 11 In this embodiment, based on the first embodiment, the retaining ring 38 can be connected to the top of the support column 37 by screw connection, so as to realize a detachable retaining ring 38; by removing the retaining ring 38, it is convenient to replace the butterfly elastic ring 32, and it is also convenient to increase or decrease the butterfly elastic ring 32 connected with the elastic clamping ring 33, so as to clamp workpieces of different widths.

[0047] Embodiment 3

[0048] See again Figure 1-Figure 13 This embodiment is based on the second embodiment, and four guide rails 7 are vertically arranged on the workbench 1, two of which are located on one side of one of the support seats 2, and the remaining two are located on one side of the other support seat 2; each guide rail 7 is respectively provided with a guide slider 8, and the guide slider 8 on each guide rail 7 is fixedly connected to the support seat 2 corresponding to the guide rail 7; the guide slider 8 cooperates with the guide rail 7, so that the support seat 2 can move up and down.

[0049] At the same time, the driving component 6 adopts a hydraulic cylinder 61, which is vertically installed on the workbench 1, and the output end of the hydraulic cylinder 61 is fixedly connected to the support seat 2; the output end of the hydraulic cylinder 61 is extended and retracted up and down, so that the support seat 2 can be driven to move up and down, so that the pressure head 52 can press the pressure ring 34 down.
