DETAILED DESCRIPTION
[0029] The following is combined with Figure 2 This application is described in further detail.
[0030] An embodiment of the present application discloses a clamp for welding an excavator cover plate.
[0031] Reference Figure 2 The fixture for welding the excavator cover plate includes a base 6, on which a first fixing unit for fixing the arc bottom plate 1, a second fixing unit for fixing the arc vertical plate 2, and a third fixing unit for fixing the bending plate 4 are arranged. The first fixing unit includes an arc support 7 arranged on the base 6 and matching the size of the arc bottom plate 1. Two reinforcing ribs 23 are welded on the side of the arc support 7, and the two reinforcing ribs 23 are both located between the base 6 and the arc support 7. The reinforcing ribs 23 improve the strength of the arc support 7, reduce the possibility of deformation of the arc support 7 during welding, and improve the stability of the arc support 7.
[0032] Reference Figure 2 , a support seat 10 is provided on the base 6. In the embodiment of the present application, the support seat 10 is plugged into the base 6. A support plate 11 is provided on the support seat 10. An arc groove 12 matching the size of the protrusion 3 is provided on the surface of the support plate 11 facing the arc bottom plate 1. The outer convex surface of the arc plate is mounted on the arc support 7 and the protrusion 3 of the arc bottom plate 1 is mounted on the arc groove 12. The support plate 11 supports the protrusion 3 of the arc bottom plate 1, reduces the possibility of shaking at the protrusion 3 of the arc bottom plate 1 during welding, further improves the stability of the placement of the arc bottom plate 1, and improves the quality of the weld.
[0033] Reference Figure 2 The base 6 is bolted with a limit seat 8, and the arc support 7 is provided with a first quick clamp 9. The arc bottom plate 1 is pressed tightly between the clamp end of the first quick clamp 9 and the limit seat 8, and the end surface of the limit seat 8 facing the protrusion 3 is in contact with the protrusion 3. The arc bottom plate 1 is pressed tightly between the clamp end of the first quick clamp 9 and the limit seat 8 by the first quick clamp 9, thereby reducing the possibility of shaking of the arc bottom plate 1, achieving the independent fixation of the arc bottom plate 1 and improving the stability of the placement of the arc bottom plate 1.
[0034] Reference Figure 2 The second fixing unit includes a fixing frame 13 hinged on the arc support 7, the fixing frame 13 includes a first arc plate 14 and a second arc plate 15, the arc vertical plate 2 is inserted between the first arc plate 14 and the second arc plate 15, and a limiting plate 16 is also hinged on the arc support 7, the limiting plate 16 is located between the first arc plate 14 and the second arc plate 15, and the arc vertical plate 2 is pressed between the limiting plate 16 and the arc bottom plate 1.
[0035] Reference Figure 2The first curved plate 14 is provided with a mounting bolt 17, which passes through the first curved plate 14, the limit plate 16 and the second curved plate 15 in sequence. The mounting bolt 17 is threadedly connected with a mounting nut 18 matching the mounting bolt 17, and the second curved plate 15 is pressed between the mounting nut 18 and the mounting bolt 17. The first curved plate 14, the limit plate 16 and the second curved plate 15 are connected as a whole by the mounting bolt 17, so that the operator can lift or put down the first curved plate 14, the limit plate 16 and the second curved plate 15 at the same time, thereby improving the convenience of operation.
[0036] Reference Figure 2 A second quick clamp 19 is provided on the arc support 7, and the fixing frame 13 is pressed between the clamp end of the second quick clamp 19 and the arc bottom plate 1. The fixing plate is pressed between the clamp end of the second quick clamp 19 and the arc bottom plate 1 by the second quick clamp 19, which reduces the possibility of shaking of the fixing frame 13, thereby improving the stability of the placement of the arc riser 2 and the arc bottom plate 1.
[0037] Therefore, when it is necessary to weld the arc vertical plate 2 to the arc bottom plate 1, the operator places the arc vertical plate 2 on the inner concave surface of the arc bottom plate 1, and then puts down the first arc plate 14, the limiting plate 16 and the second arc plate 15, so that the arc vertical plate 2 is inserted between the first arc plate 14 and the second arc plate 15 and the arc vertical plate 2 is pressed tightly between the limiting plate 16 and the arc bottom plate 1, thereby fixing the arc vertical plate 2, reducing the possibility of shaking of the arc vertical plate 2 during welding, facilitating the operator to perform welding operations, and improving the quality of the weld.
[0038] Reference Figure 2 The third fixing unit includes a positioning column 20 which is threadedly connected to the limit seat 8 and matches the two bending nuts 5 of the bending plate 4 respectively. The two positioning columns 20 are threadedly connected to the bending nuts 5 respectively. The second arc plate 15 is provided with placement grooves 21 corresponding to the two ends of the bending plate 4. The size of the placement grooves 21 is slightly larger than the size of the bending plate 4. The bending plate 4 is mounted on the inner concave surface of the arc bottom plate 1 and the two ends of the bending plate 4 are in contact with the arc vertical plate 2 after the placement grooves 21 are penetrated. The two positioning columns 20 are fixedly connected with a handle 22 at one end away from the limit seat 8. In the embodiment of the present application, the handle 22 is a T-shaped handle 22. The operator can easily rotate the positioning column 20 through the handle 22, so that the positioning column 20 passes through the limit seat 8 and is threadedly connected to the bending nut 5, which saves time and effort and improves the convenience of operation.
[0039] Therefore, when the bent plate 4 needs to be welded to the arc bottom plate 1, the bent plate 4 is placed on the inner concave surface of the arc bottom plate 1. After the bent plate 4 is pressed tightly between the limit seat 8 and the arc vertical plate 2, the operator rotates the two positioning columns 20 so that the two positioning columns 20 are respectively threadedly connected to the bending nuts 5, thereby fixing the bent plate 4, reducing the possibility of shaking of the bent plate 4 during welding, facilitating the operator to perform welding operations, and improving the quality of the weld.
[0040] The implementation principle of the embodiment of the present application is as follows: when it is necessary to weld the excavator cover plate, the operator sets the arc bottom plate 1 on the arc support 7, so that the end face of the protrusion 3 facing the limit seat 8 contacts the limit seat 8, and uses the first quick clamp 9 to press the arc bottom plate 1 between the clamp end of the first quick clamp 9 and the limit seat 8. The operator places the arc vertical plate 2 and the bending plate 4 on the inner concave surface of the arc bottom plate 1 respectively, so that the surface of the bending plate 4 facing the limit seat 8 contacts the limit seat 8, and then puts down the first arc plate 14, the limit plate 16 and the second arc plate 15, so that the arc vertical plate 2 is inserted between the first arc plate 14 and the second arc plate 15 and the arc vertical plate 2 is pressed between the limit plate 16 and the arc bottom plate 1, thereby fixing the arc vertical plate 2. Then the operator rotates the two positioning columns 20 so that the two positioning columns 20 are respectively threadedly connected with the bending nuts 5, thereby fixing the bending plate 4. Finally, the operator uses a welding robot to intermittently weld the inner concave surface of the arc bottom plate 1 and the end face where the arc vertical plate 2 contacts, and to intermittently weld the inner concave surface of the arc bottom plate 1 and the contact surface of the bent plate 4, so that the arc bottom plate 1, the arc vertical plate 2 and the bent plate 4 are welded and connected as one.
[0041] The arc bottom plate 1 is fixed by the first fixing unit, the arc vertical plate 2 is fixed by the second fixing unit, and the bent plate 4 is fixed by the third fixing unit. This makes it convenient for operators to perform welding operations. During the welding process, the arc bottom plate 1, the arc vertical plate 2, and the bent plate 4 are not prone to shaking, thereby improving the weld quality and production efficiency.
