[0024] like Figure 1 、 Figure 2 and Figure 3 As shown, a bulldozer cab welding tooling includes a tooling platform 1, on which a side positioning structure, a front rotating positioning frame 4 and a bottom plate positioning assembly 5 are installed;
[0025] The side positioning structure includes a left positioning assembly and a right positioning assembly installed on the tooling platform 1. The left and right positioning assemblies each include a positioning stand. A quick clamp flip positioning seat 6, a top crossbeam swing arm support assembly 7 and a quick clamp tightening seat 8 are installed on the positioning stand. The side positioning structure is used to position the left and right sides of the cab;
[0026] The front rotating positioning frame 4 is installed on the front side of the tooling platform 1, and includes a base 10 installed on the tooling platform 1, a rotary arm frame 9 rotatably installed on the base 10, and a support block 11 installed on the top of the rotary arm frame 9. The front rotating positioning frame 4 is used to position the angle formed by the front ends of the left and right sides of the cab, and can be rotated forward and tilted down to facilitate the removal of the cab after welding is completed;
[0027] The bottom plate positioning assembly 5 is installed on the tooling platform 1 to position and fix the cab bottom plate.
[0028] In some embodiments, as Figure 1 、 Figure 2 As shown, the left positioning assembly includes a left positioning stand 3, on which a quick clamp flip positioning seat 6, a top crossbeam swing arm support assembly 7 and a quick clamp tightening seat 8 are installed;
[0029] The right positioning assembly is arranged symmetrically with the left positioning assembly. The right positioning assembly includes a right positioning frame 2, on which a quick clamp flip positioning seat 6, a top beam swing arm support assembly 7 and a quick clamp tightening seat 8 are also installed;
[0030] After the left and right positioning assemblies are placed in appropriate positions on the cab side panels, the positioning seats 6 are flipped inward to the positioning dimensions by the quick clamp, and the side panels are pushed and fixed by the quick clamp tightening seat 8.
[0031] In some embodiments, as Figure 1 、 Figure 2 As shown, the quick clamp flip positioning seat 6 and the quick clamp tightening seat 8 are both installed in the middle and top of the positioning frame, and the top crossbeam swing arm support assembly 7 is installed on the front and rear sides of the upper part of the positioning frame.
[0032] In some embodiments, as Figure 1 、 Figure 2 As shown, the top cross beam swing arm support assembly 7 includes a mounting base mounted on a positioning frame, a swing arm 18 rotatably mounted on the mounting base, and a support block 17 detachably mounted on the swing arm 18. When the swing arm 18 of the top cross beam swing arm support assembly 7 rotates inward, the cab top cross beam is supported by the support block 17. The support block 17 is detachable to facilitate the entry and exit of the swing arm 18. For example, the support block 17 is inserted into the swing arm 18 through the bottom, making it easy to assemble and disassemble.
[0033] In some embodiments, as Figure 1 、 Figure 2 As shown, the base plate positioning assembly 5 includes a tightening seat 13, a threaded pin 14, a positioning block 15, a positioning seat 16 and a base plate hole positioning block 19 respectively installed on the tooling platform 1. When the cab base plate is hoisted onto the bulldozer cab welding tooling, the tightening seat 13 tightens the left and right side pieces to adjust the angle to facilitate the cab base plate to fall onto the positioning block 15. The positioning seat 16 supports the rear part of the base plate, and the mounting holes on the base plate coincide with the holes on the base plate hole positioning block 19, and then are positioned and fixed by the threaded pin 14.
[0034] In some embodiments, as Figure 1 、 Figure 2 As shown, a gas spring 12 is installed at the bottom of the front rotating positioning frame 4, which makes the process of laying down and standing up the rotating arm frame 9 in the front rotating positioning frame 4 more convenient and labor-saving.
[0035] In some embodiments, as Figure 1 、 Figure 2 As shown, the tooling platform 1 is made of welded steel plates and channel steels, with a stable structure and good strength. Standard 20mm horizontal and vertical square grooves are processed on the upper plane of the tooling platform 1 as a reference to facilitate subsequent three-coordinate detection; hanging plates are welded around the tooling platform 1 to facilitate the transportation of tooling.
[0036] When using, such as Figure 3As shown, the cab floor is hoisted onto the tooling, the mounting holes on the cab floor coincide with the holes on the floor hole positioning block 19, and are positioned and fixed by the threaded pin 14;
[0037] After lifting the left and right side panels of the cab and placing them in the appropriate positions, the positioning seat 6 is flipped inward by the quick clamp to adjust the positioning size. The positioning block 15 at the bottom supports the side panel to ensure the height. At the same time, the front and rear positions of the side panels are positioned. At the same time, the quick clamp tightening seat 8 installed on the positioning frame is pushed to tighten and fix the left and right side panels. The top crossbeam swing arm support assembly 7 is installed at the top position of the front and rear sides of the positioning frame. The swing arm 18 rotates inward, and the support block 17 on the swing arm 18 supports the top crossbeam of the cab.
[0038] After the left and right side panels are fixed, the swing arm frame 9 of the front rotating positioning frame 4 is rotated and raised. The support block 11 on the swing arm frame 9 is aligned with the angle of the front section of the cab. The front ends of the left and right sides of the cab are fixed to the support block 11 using F calipers to ensure the product size requirements. After the welding is completed, the front rotating positioning frame 4 can be tilted forward to facilitate the removal of the cab after the welding is completed.
[0039] The bulldozer cab welding fixture of the present invention can quickly locate and fix the positions of various components of the bulldozer cab when in use, ensure the welding size of the cab, have reliable positioning, fast and convenient clamping, reduce manual marking and measurement work, and improve welding quality and welding efficiency.
[0040] Furthermore, those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are also intended to fall within the scope of protection of the present invention and form different embodiments. For example, in the above embodiments, those skilled in the art will be able to use them in combination based on the known technical solutions and the technical problems to be solved by this application.
