[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The following is combined with Figure 1 —4 Provide further details of this application.

[0020] A fast and accurate positioning excavator frame comprises a frame body 1 and a support beam 2.

[0021] A positioning hole 3 is provided on the frame body 1, and a clearance hole 4 is provided on the support beam 2. The positioning hole 3 and the clearance hole 4 are coaxially arranged, a positioning rod 5 is placed in the clearance hole 4, a limiting platform 6 is fixedly provided on the side of the positioning rod 5 close to the clearance hole 4, a limiting groove 7 is provided on the positioning rod 5 at a position away from the limiting platform 6, and a clamping mechanism 8 is clamped on the limiting groove 7.

[0022] A docking block 9 is fixedly provided on the support beam 2 at a position away from the support beam 2 , and a docking port 10 corresponding to the docking block 9 is provided on the frame body 1 , and the docking block 9 is plugged into the docking port 10 .

[0023] The clamping mechanism 8 includes a clamping portion 11 and a pressing portion 12. The clamping portion 11 is circular. The pressing portions 12 are fixedly arranged at both ends of the clamping portion 11. When the two pressing portions 12 approach each other, the clamping portion 11 expands along the formed circle. A steel wire rope 13 is connected to the pressing portion 12, and the other end of the steel wire rope 13 is fixedly arranged on the limit platform 6.

[0024] The implementation principle of this embodiment is as follows: when welding the support beam 2, the positioning hole 3 and the clearance hole 4 are first arranged coaxially, and the docking block 9 is placed in the docking port 10, so that the support beam 2 is placed at a predetermined position of the frame body 1; then the positioning rod 5 is inserted into the clearance hole 4, and the two pressing parts 12 of the clamping mechanism 8 are pressed to make them close to each other, so that the clamping part 11 can be sleeved on the positioning rod 5, and then move to the limiting groove 7 until the clamping part 11 is engaged in the limiting groove 7, the positioning rod 5 is fixed, the positioning of the support beam 2 is completed, and the welding of the frame body 1 and the support beam 2 can be carried out; when the welding operation is completed, the two pressing parts 12 of the clamping mechanism 8 are pressed again to make them close to each other, so that the clamping part 11 is disengaged from the limiting groove 7, and then move in the direction of disengaging from the positioning rod 5 until the clamping part 11 is disengaged from the positioning rod 5, and then the positioning rod 5 can be removed from the clearance hole 4.
