[0003] However, in the existing technology, the current manufacturing process is that one tooling is used to weld a wall-mounted trapezoidal frame of one specification, and there is no quick clamping function. There are multiple specifications of trapezoidal frames for wall mounting, which requires the production of multiple sets of welding tooling, which takes up a lot of space and is troublesome to manage. Secondly, the tooling does not have a quick clamping function, resulting in low clamping efficiency, which is not conducive to disassembly and assembly and affects the production cycle. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the existing technology, namely, that the current manufacturing process uses one tooling to weld a wall-mounted trapezoidal frame of one specification, and there is no quick clamping function. There are multiple specifications of trapezoidal frames for wall mounting, requiring the manufacture of multiple sets of welding tooling, which occupies a lot of space and is troublesome to manage; secondly, the tooling does not have a quick clamping function, resulting in low clamping efficiency, which is not conducive to disassembly and assembly, and affects the production cycle.

[0006] In a preferred embodiment, a fixing block is fixedly installed on the top of each of the push-pull clamps near one end.

[0007] The technical effect of adopting the above-mentioned further solution is that the fixing block can increase the friction between itself and the trapezoidal frame body, preventing shaking during welding.

[0008] In a preferred embodiment, a plurality of positioning blocks and a plurality of positioning sleeves are fixedly installed on the outer surface of the welding frame, and positioning pins are movably embedded in the inner cavities of the plurality of positioning blocks and positioning sleeves.

[0009] The technical effect of adopting the above-mentioned further solution is that the positioning pin and positioning block can fix and limit the parts with holes in the trapezoidal frame body, which can better prevent misalignment during welding.

[0010] In a preferred embodiment, a fixing sleeve is movably fitted onto the outer surface of each of the plurality of positioning pins, and a plurality of positioning holes are provided on the outer surface of the welding frame near the top.

[0011] The technical advantage of adopting the above-mentioned further solution is that multiple positioning holes have different diameters, which can be used for precise positioning according to different specifications of the trapezoidal frame body.

[0012] In a preferred embodiment, limiting plates are fixedly installed on both sides of the top outer surface of the welding frame, and the outer surfaces of the multiple limiting plates are provided with slots.

[0013] The technical effect of adopting the above-mentioned further solution is that the limiting plate can better limit the trapezoidal frame body, and the bayonet can also limit the trapezoidal frame body.

[0014] In a preferred embodiment, a support plate 1 is fixedly installed on the outer surface of the welding frame near one end, and support plates 2 are fixedly installed on the outer surfaces of the welding frame near both sides. A trapezoidal frame body is movably embedded in the outer surface of the welding frame.

[0016] In a preferred embodiment, connecting shafts are fixedly installed on the outer surfaces of the welding frame near both sides.

[0017] The technical effect of adopting the above-mentioned further solution is that it can better drive the trapezoidal frame body to rotate, and can weld on its back side, realizing welding on both sides and improving welding efficiency.

[0018] The present invention also provides a welding method for a wall-mounted trapezoidal frame welding fixture for a hoist, comprising the following steps:

[0019] (1) Place the trapezoidal frame body onto the support plate one and support plate two on the surface of the welding frame;

[0020] (2) Fix and limit the parts with holes in the trapezoidal frame body by using positioning sleeves and positioning pins;

[0021] (3) Push the push-pull clamping clamp to quickly clamp the trapezoidal frame body in the horizontal direction, and the fixing block fixes and limits the trapezoidal frame body;

[0022] (4) Use the vertical clamping clamp to quickly clamp the trapezoidal frame body vertically;

[0023] (5) With the help of a rotating connecting shaft to drive the trapezoidal frame body to rotate, welding work can be carried out on both sides.

[0024] (6) After welding is completed, open the push-pull clamp, remove the positioning pin, and you can take off the welded workpiece.

[0025] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0026] 1. The wall-mounted trapezoidal frame welding fixture of the present invention, when in use, places the trapezoidal frame body on the support plate one and support plate two on the surface of the welding frame, and then fixes and limits the parts with holes on the trapezoidal frame body by positioning sleeve and positioning pin, which can better prevent misalignment during welding. The welding frame has positioning holes of different diameters, and different paint colors are used to distinguish them to correspond to different specifications of trapezoidal frame bodies, which can realize the rapid identification and accurate positioning of different products.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-4 The present invention provides a technical solution: a welding fixture for a trapezoidal frame for a lift, comprising: a welding frame 1, a plurality of installers 103 fixedly installed on the outer surface of the welding frame 1 near the top, a vertical clamping clamp 7 fixedly installed on the top of each of the plurality of installers 103, an anti-slip block 701 fixedly installed on one end of each of the plurality of vertical clamping clamps 7, and installers 2 105 fixedly installed on both sides of the outer surface of the welding frame 1 near the top, and push-pull clamping clamps 6 fixedly installed on the top of each of the plurality of installers 2 105.

[0037] like Figure 1-4 As shown, a fixing block 5 is fixedly installed on the top of each of the multiple push-pull clamping clamps 6 near one end. The fixing block 5 can increase the friction between the clamp and the trapezoidal frame body 2 and prevent shaking during welding.

[0038] like Figure 1-4 As shown, multiple positioning blocks 102 and multiple positioning sleeves 401 are fixedly installed on the outer surface of the welding frame 1. Positioning pins 3 are movably embedded in the inner cavities of the multiple positioning blocks 102 and positioning sleeves 401. The positioning pins 3 and positioning blocks 102 can fix and limit the parts with holes in the trapezoidal frame body 2, which can better prevent misalignment during welding.

[0039] like Figure 1-4 As shown, a fixing sleeve 301 is movably fitted on the outer surface of multiple positioning pins 3, and multiple positioning holes 4 are opened on the outer surface of the welding frame 1 near the top. The multiple positioning holes 4 have different diameters, which can be accurately positioned according to the trapezoidal frame body 2 of different specifications.

[0040] like Figure 1-4As shown, limit plates 104 are fixedly installed on both sides of the top outer surface of the welding frame 1. The outer surfaces of the multiple limit plates 104 are provided with slots 106. The limit plates 104 can better limit the trapezoidal frame body 2, and the slots 106 can also limit the trapezoidal frame body 2.

[0041] like Figure 1-4 As shown, a support plate 107 is fixedly installed on the outer surface of the welding frame 1 near one end, and a support plate 108 is fixedly installed on the outer surfaces of the welding frame 1 near both sides.

The support plate 107 and the support plate 108 can more easily lift the trapezoidal frame body 2, making welding easier.

[0042] like Figure 1-4 As shown, the welding frame 1 has connecting shafts 101 fixedly installed on the outer surfaces near both sides, which can better drive the trapezoidal frame body 2 to rotate, and can weld on its back side, realizing welding on both sides and improving welding efficiency.

[0043] A welding method for a wall-mounted trapezoidal frame welding fixture for a lifting platform includes the following steps: placing the trapezoidal frame body 2 onto the support plate 107 and support plate 108 on the surface of the welding frame 1; then fixing and limiting the parts with holes in the trapezoidal frame body 2 using the positioning sleeve 401 and positioning pin 3 to better prevent misalignment during welding; the welding frame 1 has positioning holes 4 of different diameters, which are distinguished by different paint colors to correspond to different specifications of the trapezoidal frame body 2, enabling rapid identification and precise positioning of different products; then pushing and pulling the clamping clamp 6 to horizontally position the trapezoidal frame body 2. The quick clamping mechanism, with a fixed block 5 fixedly installed at one end of the push-pull clamping clamp 6, makes it easier to fix and limit the trapezoidal frame body 2. The vertical clamping clamp 7 is moved to quickly clamp the trapezoidal frame body 2 vertically. An anti-slip block 701 is fixedly installed at one end of the vertical clamping clamp 7 to increase friction and prevent the trapezoidal frame body 2 from shaking during welding. Connecting shafts 101 are fixedly installed on both sides of the welding frame 1. Rotating the connecting shafts 101 allows welding to be performed on the back of the trapezoidal frame body 2, which can better improve the welding efficiency and firmness. Rotating the connecting shafts 101 also reduces the labor intensity.

[0044] The welding process of the hoist wall-mounted trapezoidal frame welding fixture of the present invention can realize multi-purpose use of one mold and quick assembly and disassembly of workpieces. Its production efficiency is more than 3 times higher than that of traditional fixtures, space utilization is more than 2 times higher, and quality is also steadily improved.
