[0002] The excavator bracket is one of the important components connecting the excavator upper frame and the cab. It is usually made of sheet metal. During the production process of the excavator bracket, the various components need to be welded into a whole.

[0003] Reference Figure 1 The excavator support includes a transverse plate 1, on which an articulated frame 2 is welded, the articulated frame 2 is composed of two articulated plates 3 and an articulated column 4, wherein the articulated column 4 is located between the two articulated plates 3, and a support column 5 is welded on the surface of the transverse plate 1 away from the articulated frame 2. The excavator support 8 also includes a bottom block 6, on which two mounting holes 7 are provided.

[0006] Through the above technical solution, when the support column and the bottom block need to be welded, the second clamping assembly is activated to clamp and fix the horizontal plate, and then the bottom push cylinder is activated to drive the support plate to move toward the support column. When the end face of the bottom block facing the horizontal plate contacts the end face of the support column away from the horizontal plate, the operator then uses the welding equipment to weld the support column and the bottom block into a whole. The first clamping assembly and the second clamping assembly are used to fix the bottom block and the horizontal plate respectively, which is convenient for the operator to perform welding operations and is not easy to shake during the welding process, thereby improving the weld quality and production efficiency.

[0015] In a specific possible implementation scheme, an auxiliary stopper is provided on the mounting plate, and the cross plate is pressed tightly between the auxiliary stopper and the pushing cylinder.

[0030] The following is combined with Figure 2-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a welding clamping tool.

[0032] Reference Figure 2The welding clamping tooling includes a bracket 8, a mounting plate 9 is arranged on the bracket 8, a first clamping assembly 10 for fixing the bottom block 6 is arranged on the mounting plate 9, and the first clamping assembly 10 includes a bottom push cylinder 13 arranged on the mounting plate 9, a support plate 14 is fixedly connected to the output end of the bottom push cylinder 13, a positioning block 15 matching the mounting hole 7 of the bottom block 6 is fixedly connected to the support plate 14, and a chamfer is arranged at one end of the positioning block 15 away from the support block to facilitate the installation of the support block, and the bottom block 6 is mounted on the positioning block 15 and the positioning block 15 passes through the mounting hole 7 of the bottom block 6. A second support block 33 is arranged on the mounting plate 9, and the cross plate 1 is mounted on the second support block 33. The second support block 33 supports the cross plate 1, reduces the possibility of shaking of the cross plate 1, and improves the stability of the placement of the cross plate 1 during welding.

[0033] Reference Figure 2 , the mounting plate 9 is bolted with a bottom push seat 16, the bottom push cylinder 13 is arranged on the bottom push seat 16, the support plate 14 is bolted with a guide rod 17 on the surface facing the bottom push seat 16, the bottom push seat 16 is provided with a guide hole 18 matching the size of the guide rod 17, and the guide rod 17 passes through the guide hole 18. When the bottom push cylinder 13 is started, the support plate 14 drives the guide rod 17 to slide along the guide hole 18, and the guide hole 18 limits the position of the guide rod 17, thereby improving the stability of the bottom push cylinder 13 when driving the support plate 14 to move. A bottom push plate 19 is bolted with a bottom push plate 19, and a bottom push block 20 is fixedly connected to the bottom push plate 19, and the bottom block 6 is pressed tightly between the bottom push block 20 and the support plate 14. When the bottom block 6 is mounted on the positioning block 15, the bottom push block 20 limits the position of the bottom block 6, thereby reducing the possibility of the bottom block 6 falling off from the support plate 14 and improving the stability of the bottom plate placed on the support plate 14.

[0034] Reference Figure 2 , a second clamping assembly 11 for clamping the cross plate 1 is provided on the mounting plate 9. In the embodiment of the present application, the second clamping assembly 11 is provided in two groups and is evenly distributed relative to the cross plate 1. The second clamping assembly 11 includes a pushing cylinder 21 provided on the mounting plate 9. A pushing stopper 22 corresponding to the position of the output end of the pushing cylinder 21 is bolted to the mounting plate 9. The cross plate 1 is pressed tightly between the pushing stopper 22 and the output end of the pushing cylinder 21. A pushing block 23 is provided at the output end of the pushing cylinder 21. The cross plate 1 is pressed tightly between the stopper and the pushing block 23. The pushing block 23 increases the contact area between the output end of the pushing cylinder 21 and the cross plate 1, reduces the possibility of deformation of the contact position between the output end of the pushing cylinder 21 and the cross plate 1, and improves the stability of clamping the cross plate 1.

[0035] Therefore, the pushing cylinder 21 is started, and the output end of the pushing cylinder 21 pushes the cross plate 1 to move, and the cross plate 1 is pressed tightly between the pushing stop seat 22 and the output end of the pushing cylinder 21 to fix the position of the cross plate 1, thereby reducing the possibility of shaking and shifting of the cross plate 1, and facilitating the operator to perform subsequent welding operations.

[0036] Reference Figure 2 The mounting plate 9 is bolted with an auxiliary stopper 24, and the cross plate 1 is pressed tightly between the auxiliary stopper 24 and the pushing cylinder 21. The auxiliary stopper 24 is located on the side of the cross plate 1 close to the support column 5. The auxiliary stopper 24 supports the cross plate 1 and limits the position of the cross plate 1, thereby improving the stability of the cross plate 1 being clamped.

[0037] Reference Figure 2 The mounting plate 9 is also provided with a third clamping assembly 12 for clamping the hinge column 4. In the embodiment of the present application, the third clamping assembly 12 is provided in two groups and is evenly distributed relative to the horizontal plate 1. The third clamping assembly 12 includes a clamping oil cylinder 25 provided on the mounting plate 9, and a clamping pressure plate 26 is provided at the output end of the clamping oil cylinder 25. A positioning seat 27 matching the shape of the hinge column 4 is bolted to the mounting plate 9, and the hinge column 4 is mounted on the positioning seat 27 and is pressed between the positioning seat 27 and the clamping pressure plate 26.

[0038] Therefore, the positioning seat 27 supports the hinged column 4 and limits the position of the hinged column 4. The clamping cylinder 25 is started and the clamping plate 26 presses the hinged column 4 between the positioning seat 27 and the clamping plate 26 for positioning, thereby reducing the possibility of shaking of the hinged column 4 and improving the stability of the placement and welding operation of the cross plate 1.

[0039] Reference Figure 2 and Figure 3 A fourth clamping assembly 34 for clamping the support column 5 is provided on the mounting plate 9. The fourth clamping assembly 34 includes a side thrust cylinder 28 arranged on the mounting plate 9. A side thrust block seat 29 corresponding to the output end position of the side thrust cylinder 28 is bolted to the mounting plate 9. The support column 5 is pressed between the side thrust block seat 29 and the output end of the side thrust cylinder 28.

[0040] Therefore, the side-thrust cylinder 28 is started, and the output end of the side-thrust cylinder 28 pushes the support column 5 to move. The output end of the side-thrust cylinder 28 can be set with a push block 23 corresponding to the output end of the push cylinder 21, and the support column 5 is pressed between the side-thrust block seat 29 and the output end of the side-thrust cylinder 28 to fix the position of the support column 5, thereby reducing the possibility of the support column 5 shaking and shifting, and facilitating the subsequent welding operation of the operator. During the production process of the excavator support, the support column 5 may be tilted or offset when being welded to the cross plate 1. The side-thrust cylinder 28 pushes the support column 5 to press against the side-thrust block seat 29, which will calibrate the position of the support column 5, so that the position of the support column 5 perpendicular to the cross plate 1 is more accurate.

[0041] Reference Figure 2 and Figure 3 , a rotating oil cylinder 30 is arranged on the mounting plate 9, an auxiliary pressing plate 31 is arranged at the output end of the rotating oil cylinder 30, a first supporting block 32 corresponding to the auxiliary pressing plate 31 is bolted to the side thrust block seat 29, and the supporting column 5 is pressed tightly between the auxiliary pressing plate 31 and the first supporting block 32. When the supporting column 5 is pressed tightly between the side thrust block seat 29 and the output end of the side thrust oil cylinder 28, the rotating oil cylinder 30 is started to drive the auxiliary pressing plate 31 to rotate to the top of the supporting column 5, and the supporting column 5 is pressed tightly between the auxiliary pressing plate 31 and the first supporting block 32 to fix the position of the supporting column 5, thereby reducing the possibility of shaking and displacement of the supporting column 5, and facilitating the subsequent welding operation of the operator.

[0042] The implementation principle of the embodiment of the present application is as follows: when the support column 5 needs to be welded to the bottom block 6, the operator sets the hinge column 4 on the positioning seat 27, and the cross plate 1 on the second support block 33. Start the push cylinder 21, the output end of the push cylinder 21 pushes the cross plate 1 to move, and the cross plate 1 is pressed between the push stop seat 22 and the output end of the push cylinder 21 to fix the position of the cross plate 1, start the clamping cylinder 25, and the clamping plate 26 presses the hinge column 4 between the positioning seat 27 and the clamping plate 26 to fix it, start the side push cylinder 28, and the output end of the side push cylinder 28 pushes the support column 5 to move, and the support column 5 is pressed between the side push stop seat 29 and the output end of the side push cylinder 28 to fix the position of the support column 5. Then the bottom push cylinder 13 is started to drive the support plate 14 to move toward the support column 5. When the end surface of the bottom block 6 facing the horizontal plate 1 contacts the end surface of the support column 5 away from the horizontal plate 1, the operator uses the welding equipment to weld the support column 5 and the bottom block 6 into a whole. The first clamping assembly 10 and the second clamping assembly 11 are used to fix the bottom block 6 and the horizontal plate 1 respectively, which is convenient for the operator to perform the welding operation. At the same time, the bottom block 6 and the horizontal plate 1 are not easy to shake during the welding process, which improves the weld quality and production efficiency.
