Description

A clamp for welding right-angle rods Technical Field

[0001] This utility model belongs to the field of air cooler component manufacturing technology, and in particular relates to a fixture for welding right-angle rods. Background Technology

[0002] A right-angle bar is made of triangular steel with a right-angle cross-section and is often used as a connector. To meet the requirements of the connection angle, isosceles triangular notches of a certain angle are cut at a certain position on one of the right-angle sides at both ends using a flame cutting gun. Then, the two isosceles sides of the cut are joined together by bending, and finally welded together at the joint using a welding gun.

[0003] After a right-angle rod is bent, the elasticity of the material itself will cause it to open up. During welding, it is necessary to apply a pushing force on both sides of the joint to rejoin the cuts before welding, in order to ensure that the angles of the bent parts at both ends are consistent after forming.

[0004] This process is mostly done manually. The worker steps on the horizontal right-angle side of the middle horizontal section of the right-angle rod with one foot, then uses the other foot to brace against the outside of the vertical right-angle side of the middle horizontal section, and uses one hand to move one end of the right-angle rod to reconnect the cuts. Finally, the welding is carried out. After welding one end, the above operation is repeated to weld the other end, which is time-consuming and laborious. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this utility model provides a clamp for welding right-angle rods, which can automatically align the notches at both ends of the right-angle rod during welding, making operation convenient and efficient.

[0006] In order to achieve the purpose of this utility model, the following solution is proposed:

[0007] A clamp for welding right-angle bars includes an operating table and a clamp assembly disposed on the operating table;

[0008] The operating platform includes a water platform with a vertical plate on one side. The inner side of the vertical plate has a strip groove, and the opening direction of the strip groove is rotated to provide a set of symmetrically arranged rotating plates.

[0009] The clamping assembly includes a bidirectional lead screw with both ends rotatably connected to the strip groove. The bidirectional lead screw is symmetrically provided with moving blocks. One end of the moving block is rotatably connected to the corresponding rotating plate. A clamping plate is vertically provided on the symmetrical center line of a set of moving blocks. The clamping plate is movable along the short axis of the platform.

[0010] Furthermore, the cross-section of the strip groove is a horizontally arranged T-shaped structure, and one end of the rotating plate is perpendicular to the vertical part of the T-shaped strip groove.

[0011] Furthermore, the movable block has a horizontally arranged I-shaped structure, with one end of its horizontal part slidingly disposed in the strip groove and threadedly connected to the bidirectional lead screw, and the other end of its horizontal part extending out of the strip groove.

[0012] Furthermore, the other end of the I-shaped movable block is equipped with connecting rods on the upper and lower layers of the horizontal part, and one end of the connecting rod is rotatably connected to the upper and lower sides of the corresponding rotating plate.

[0013] Furthermore, a handwheel is connected to one end of the two-way lead screw after it extends out of the vertical plate.

[0014] Furthermore, the upper end of the card plate is provided with a telescopic rod, and the upper end of the upright plate is vertically provided with an L-shaped connecting seat. The inner right angle of the connecting seat is inward, and its horizontal part is provided with a sliding groove. The upper end of the telescopic rod is slidably connected to the sliding groove.

[0015] Furthermore, a bevel is provided on one side of the lower end of the card plate.

[0016] The beneficial effects of this utility model are as follows:

[0017] The system uses a locking block to limit the middle horizontal section of the right-angle rod, and a bidirectional screw to synchronously drive the moving block. The position of the moving block on the bidirectional screw controls the angle between the rotating plate and the upright plate, thereby satisfying the connection at the notch of the right-angle rod with different bending angles, reducing the labor intensity of workers and improving work efficiency.

Detailed Implementation

[0025] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0026] As shown in Figures 1-5, this embodiment provides a fixture for welding right-angle bars, including an operating table 10 and a fixture assembly 20 disposed on the operating table 10.

[0027] Specifically, as shown in Figures 1 and 4, the operating platform 10 includes a water platform 11 and a vertical plate 12. The water platform 11 has a rectangular plate structure and is horizontally fixed on a frame for placing the right-angle rod 1 to be welded. The vertical plate 12 is vertically arranged on the outside of the water platform 11 along its length.

[0028] A strip groove 121 is provided in the inner right-angle direction at the connection between the upright plate 12 and the water platform 11. The strip groove 121 is parallel to the length direction of the water platform 11, and the cross-section of the strip groove 121 is a horizontally arranged T-shaped structure, with its vertical part connected to the inner side of the upright plate 12.

[0029] A connecting seat 122 with an inverted L-shaped structure is vertically provided in the middle of the top surface of the upper side of the upright plate 12. The lower end of the vertical part of the connecting seat 122 is vertically connected to the center of the top surface of the upper side of the upright plate 12, and the inner right angle is oriented towards the direction of the horizontal 11. A sliding groove is provided on the bottom surface of the horizontal part of the connecting seat 122 with the inverted L-shaped structure. The sliding groove is located directly above the short axis of the water platform 11 and is parallel to the short axis of the water platform 11.

[0030] A set of rotating plates 13 are symmetrically arranged in the direction of the opening of the strip groove 121. The upper and lower sides of one end of the rotating plate 13 are respectively rotatably arranged with the two sides of the vertical opening of the strip groove 121, and the rotating plate 13 is perpendicular to the water platform 11.

[0031] As shown in Figures 1-3 and 5, the clamp assembly 20 includes a bidirectional lead screw 21, a moving block 22, and a clamping plate 23. The bidirectional lead screw 21 is located in the strip groove 121, and both ends of the bidirectional lead screw 21 are rotatably connected to both ends of the strip groove 121. One end of the bidirectional lead screw 21 passes through the vertical plate 12 and is equipped with a handwheel 211 for driving the bidirectional lead screw 21 to rotate. Of course, the handwheel 211 can also be replaced by a motor, and the user can choose according to the budget.

[0032] The two ends of the bidirectional lead screw 21 are respectively provided with two threaded sections with opposite directions of rotation. Two moving blocks 22 are symmetrically provided, and the moving blocks 22 are horizontally arranged in an I-shaped structure. The horizontal part of one end of the moving block 22 is slidably disposed in the strip groove 121 and threadedly connected to the corresponding threaded section of the bidirectional lead screw 21. The vertical part of the moving block 22 with the I-shaped structure is slidably connected to the vertical part of the strip groove 121. The horizontal part of the other end of the moving block 22 with the I-shaped structure extends out of the strip groove 121.

[0033] The movable block 22 with an I-shaped structure extends out of the horizontal part of the strip groove 121 and is provided with connecting rods 221 on the upper and lower sides respectively. One end of the connecting rod 221 is rotatably connected to the upper and lower sides of the rotating plate 13 extending to the water platform 11, so that the movable block 22 is located in the area between the end of the rotating plate 13 and the end of the strip groove 121, which is used to control the included angle between the rotating plate 13 and the vertical plate 12.

[0034] It is worth noting that the included angle at the connection between the connecting rod 221 and the rotating plate 13 shall not be less than 90°.

[0035] The clamping plate 23 is parallel to the side of the upright plate 12 facing the water platform 11. The upper end of the clamping plate 23 is provided with a telescopic rod 231. The upper end of the telescopic rod 231 is slidably connected to the sliding groove of the horizontal part of the connecting seat 122 to adjust the distance between the clamping plate 23 and the upright plate 12. The bottom of the clamping plate 23 is provided with an inclined surface 232 on the side facing the upright plate 12. When the horizontal section of the right angle rod 1 is placed in front of the upright plate 12, the clamping plate 23 is vertically downward and, under the action of the inclined surface 232, pushes the horizontal section of the right angle rod 1 to stick tightly to the upright plate 12.

[0036] The specific usage process is as follows:

[0037] Place the right-angle rod 1 to be welded on the top surface of the platform 11, with the bent ends of the right-angle rod 1 facing away from the vertical plate 12. That is, place the bent ends between a set of rotating plates 13, and make the horizontal section in the middle of the right-angle rod 1 close to the vertical plate 12. Adjust the telescopic rod 231 according to the thickness of the right-angle side of the horizontal section in the middle of the right-angle rod 1, so that the horizontal distance between the clamping plate 23 and the vertical plate 12 is consistent with the thickness of the right-angle side of the horizontal section in the middle of the right-angle rod 1.

[0038] Make the telescopic rod 231 vertically downward, so that the push plate 23 moves vertically downward to the middle horizontal section of the right-angle rod 1, and keep the upward right-angle side of the middle horizontal section of the right-angle rod 1 pressed against the side of the upright plate 12 facing the water platform 11, thereby achieving the limitation of the horizontal section of the right-angle rod 1.

[0039] Rotating the handwheel 211 causes the bidirectional lead screw 21 to rotate, thereby controlling the position of the moving block 22 on the bidirectional lead screw 21. The moving block 22 moves along the bidirectional lead screw 21 towards the corresponding rotating plate 13, so that the connecting rod 221 pushes one end of the rotating plate 13 on the horizontal platform 11 towards the two bent edges of the right-angle rod 1 and abuts against the bent edges, thereby keeping the two sides of the notch at the two bent ends of the right-angle rod 1 aligned. This replaces manual positioning by workers, thereby reducing the labor intensity of workers and improving efficiency.

[0040] Finally, the contact welding was performed using a welding torch.

[0041] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
