DETAILED DESCRIPTION
[0019] The following is combined with Figure 1-4 This application is described in further detail.
[0020] The present application embodiment discloses a welding fixture for a guide seat of a crawler excavator. Figure 1-Figure 4 , including a welding table 1, the surface of the welding table 1 is symmetrically provided with through holes 8, a guide base plate 10 is installed on the outside of the through holes 8, and guide angle blocks 9 are symmetrically fixed to the edges of the guide base plate 10. An edge guide block 12 is fixed to one end of the welding table 1. By setting the guide angle blocks 9, the guide base plate 10 and the edge guide blocks 12, the corners of the guide seat half can be positioned to avoid displacement during the processing. A positioning seat 5 is installed at the center of the top of the welding table 1, and the tops of both sides of the positioning seat 5 are provided with guide half-piece outer opening positioning plates 19, and the bottom of the guide half-piece outer opening positioning plates 19 is provided with guide half-piece inner opening positioning plates 20. The guide half-piece inner opening positioning plates 20 are located in the middle and lower part of the positioning seat 5, which ensures the assembly inner opening size of the crawler excavator guide seat and has a good positioning effect.
[0021] like Figure 4 As shown, both sides of the positioning seat 5 are provided with movable cavities 11, a set of rotating shafts 17 are installed inside the movable cavity 11, and the outer side of the rotating shaft 17 is rotatably connected with a movable block 18, one end of the two sets of movable blocks 18 extends outside the movable cavity 11 and is respectively fixed to one end of the positioning plate 19 of the outer opening of the guide half piece and the positioning plate 20 of the inner opening of the guide half piece, so that the positioning plate 19 of the outer opening of the guide half piece and the positioning plate 20 of the inner opening of the guide half piece can be pushed to rotate upward outside the rotating shaft 17 along with the movable block 18, so as to flexibly release the lock of the guide seat;
[0022] A support plate 21 is provided at the bottom of the rotating shaft 17, and the internal thread of the support plate 21 is connected with a screw rod 22 for support. By adjusting the screw rod 22, the bottom of the guide half-piece outer opening positioning plate 19 and the guide half-piece inner opening positioning plate 20 can be supported to ensure the stability of their positioning.
[0023] Combination Figure 1-Figure 3As shown, the edges of the top of the welding table 1 are all installed with upright poles, and the upright poles are provided with a tightening mechanism, which includes a cylinder, a tightening block 7 and a positioning plate 15 arranged on the upright poles. The upright poles include upright pole 1 2, upright pole 2 3 and upright pole 3 4. The upright pole 1 2 is fixed to both sides of the top of the welding table 1. The center of the outer wall at both ends of the welding table 1 is welded with a fixing frame 13. The fixing frame 13 is connected to the upright pole 2 3 and the upright pole 3 4 by bolts. The height of the upright pole 2 3 is slightly higher than that of the upright pole 3 4, so that different positions of the guide seat can be supported to ensure the stability of the half-piece welding of the guide seat. .
[0024] Furthermore, the cylinder includes a tightening cylinder 1 6 and a tightening cylinder 2 14. The tightening cylinder 1 6 is fixed to the inner wall of the vertical pole 1 2, and the output end of the tightening cylinder 1 6 is connected to the back wall of the tightening block 7. The tightening cylinder 1 6 can push the tightening block 7 close to the outer wall of the guide seat half piece, so that the two guide seat half pieces can be tightened to make them fit tightly with the positioning seat 5, and the two tightening cylinders 2 14 are respectively installed on the top of the inner wall of the vertical pole 2 3 and the vertical pole 3 4, and the output end of the tightening cylinder 2 14 is connected to the back wall of the positioning plate 15. A folding plate 16 is rotatably connected to one side of the positioning plate 15. The arrangement of the positioning plate 15 and the folding plate 16 can fit the contact surfaces of the two guide seat halves to ensure the flatness during welding.
[0025] The implementation principle of the welding fixture of the guide seat of a crawler excavator in the embodiment of the present application is as follows: when in use, two guide seat halves are placed on the welding workbench 1 so that the two guide seat halves are located on both sides of the positioning seat 5. At this time, the guide seat halves are located on the guide bottom plate 10, and their corners are placed in contact with the guide angle blocks 9 and the edge guide blocks 12 for preliminary positioning. Then, the outer positioning plates 19 and the inner positioning plates 20 of the guide halves on both sides are flipped downward, and the movable block 18 is rotated and adapted outside the rotating shaft 17. At this time, the screw 22 on the supporting plate 21 can support the bottom of the outer positioning plates 19 and the inner positioning plates 20 of the guide halves to ensure that they are in a horizontal state. Then, the guide seat halves on both sides are aligned with the outer positioning plates 19 and the inner positioning plates 20 of the guide halves to ensure the size of the inner opening of the two guide seat halves when assembled.
[0026] Then start the tightening cylinder 16 on the vertical pole 2, and push the tightening block 7 close to the outer wall of the two guide seat halves through the tightening cylinder 16, and then push the positioning plate 15 and the folding plate 16 to close to the two ends of the connecting welded end faces of the two guide seat halves through the tightening cylinder 2 14 to position them. At this time, the positioning plate 15 and the folding plate 16 can also flexibly adapt to the support angle. Through the overall coordinated use, the various components of the product are closely fitted to each other, and at the same time, the assembly structure and size accuracy of the various components of the guide seat are improved, thereby ensuring the subsequent processing quality of the guide seat and the installation requirements of the whole machine.
