The opposite sides of the two moving rods penetrate through the placement frame and are fixedly connected to a control plate. A mating hole is formed in the bottom of the control plate. An extrusion rod is fixedly connected to the inner cavity of the mating hole. By providing the clamping assembly, when clamping a special-shaped air duct is required, the movement of the control plate drives the two moving rods to move, and the movement of the moving rods drives the two clamping plates to clamp the special-shaped air duct, preventing the special-shaped air duct from moving randomly.

[0013] Preferably, for the present utility model, an electric cylinder is fixedly connected to the bottom of the placement frame. The output end of the electric cylinder is fixedly connected to a special-shaped plate. Extrusion holes for cooperating with the extrusion rod are formed in the left side and the right side of the front side of the special-shaped plate.

By providing the electric cylinder, the special-shaped block and the extrusion hole, when it is required to drive the two control plates to move simultaneously, the electric cylinder is activated to drive the special-shaped plate at the output end to rise. The rising of the special-shaped plate causes the inner wall of the extrusion hole to squeeze the extrusion rod, and the extrusion of the extrusion rod drives the control plate to move.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] By using the pressing assembly, clamping assembly, support rod and connecting plate in cooperation, the present utility model starts the electric cylinder to drive the special-shaped plate at the output end to rise. The rising of the special-shaped plate will drive the inner wall of the extrusion hole to extrude the extrusion rod. When the extrusion rod is extruded, it will drive the control plate to move.

Detailed Embodiment

[0021] To further understand the content, features and effects of the present utility model, the following embodiments are exemplified and described in detail in conjunction with the drawings.

[0022] The structure of the present utility model will be described in detail below with reference to the drawings.

[0023] As Figures 1 to 4 shown, a special-shaped air duct fixing tooling provided by an embodiment of the present utility model includes a placement frame 1, a support frame 2, four support legs 3 and a moving hole 4. The right side of the placement frame 1 is movably connected to the left side of the support frame 2. The top of the support legs 3 is fixedly connected to the placement frame 1 and the support frame 2. The moving hole 4 is opened on the front side of the support frame 2;

[0024] The pressing component 5 for pressing the straight pipe is arranged on the top of the support frame 2;

[0025] The clamping component 6 for clamping the special-shaped air duct is arranged on the left and right sides of the placement frame 1.

[0027] Adopting the above scheme: By arranging the support rods 7 and the connecting plates 8, the support rods 7 can support the bottoms of the placement frame 1 and the support frame 2, and the connecting plates 8 can be connected with the legs 3, so as to increase the stability.

[0028] Reference Figure 3 , the pressing component 5 includes a lower pressing plate 501, the lower pressing plate 501 is movably connected to the inner cavity of the support frame 2, a rubber pad 502 is fixedly connected to the bottom of the lower pressing plate 501, a fixing plate 503 is fixedly connected to the top of the support frame 2, a threaded hole 504 is opened on the top of the fixing plate 503, a threaded rod 505 is threadedly connected to the inner cavity of the threaded hole 504, a rotating member 506 is fixedly connected to the top of the threaded rod 505, and the bottom of the threaded rod 505 is rotatably connected to the lower pressing plate 501 through a bearing.

[0029] Adopting the above scheme: By arranging the pressing component 5, when positioning the straight pipe is required, rotating the rotating member 506 drives the threaded rod 505 to rotate in the threaded hole 504, the rotation of the threaded rod 505 causes the lower pressing plate 501 to descend, and the lower pressing plate 501 then drives the rubber pad 502 to press the straight pipe. The rubber pad 502 can increase the friction force, and the straight pipe will not slip.

[0030] Reference Figure 3 , two sides on the front and rear sides of the support frame 2 are both provided with stroke holes 9, a stroke block 10 is slidably connected to the inner cavity of the stroke holes 9, and one side of the stroke block 10 close to the lower pressing plate 501 is fixedly connected to the lower pressing plate 501.

[0031] Adopting the above scheme: By arranging the stroke holes 9 and the stroke blocks 10, when the lower pressing plate 501 moves, the stroke blocks 10 and the stroke grooves can control the moving position of the lower pressing plate 501, so that the lower pressing plate 501 will not shake when moving.

[0032] Reference Figure 2, the clamping assembly 6 includes two clamping plates 61. On the opposite sides of the two clamping plates 61, moving rods 62 are fixedly connected. On the opposite sides of the two moving rods 62, they both penetrate through the placement frame 1 and are fixedly connected to a control plate 63. A mating hole 64 is formed at the bottom of the control plate 63, and a pressing rod 65 is fixedly connected to the inner cavity of the mating hole 64.

[0033] With the above solution: By setting the clamping assembly 6, when it is necessary to clamp the special-shaped air duct, the movement of the control plate 63 will drive the two moving rods 62 to move, and the movement of the moving rods 62 will drive the two clamping plates 61 to clamp the special-shaped air duct, so that the special-shaped air duct will not move randomly.

[0034] Reference Figure 2 , an electric cylinder 11 is fixedly connected to the bottom of the placement frame 1. The output end of the electric cylinder 11 is fixedly connected to a special-shaped plate 12. On the left and right sides of the front side of the special-shaped plate 12, pressing holes 13 for cooperating with the pressing rod 65 are formed, and the pressing rod 65 is movably connected to the inner cavity of the pressing hole 13.

[0035] With the above solution: By setting the electric cylinder 11, the special-shaped block and the pressing hole 13, when it is necessary to drive the two control plates 63 to move simultaneously, the electric cylinder 11 is turned on to drive the special-shaped plate 12 at the output end to rise. The rising of the special-shaped plate 12 will drive the inner wall of the pressing hole 13 to press the pressing rod 65, and the pressing rod 65 being pressed will drive the control plate 63 to move.

[0036] The working principle of the present utility model:

[0037] During use, first place the special-shaped air duct on the top of the placement frame 1. Subsequently, turn on the electric cylinder 11 to drive the special-shaped plate 12 at the output end to rise. The rising of the special-shaped plate 12 will drive the inner wall of the pressing hole 13 to press the pressing rod 65. The pressing rod 65 being pressed will drive the control plate 63 to move. The movement of the control plate 63 will drive the two moving rods 62 to move, and the movement of the moving rods 62 will drive the two clamping plates 61 to clamp the special-shaped air duct;

[0038] Subsequently, pick up the straight pipe welded to the special-shaped air duct and insert it into the support frame 2. After the special-shaped air duct and the straight pipe are perfectly docked, rotate the rotating member 506 to drive the threaded rod 505 to rotate in the threaded hole 504. The rotation of the threaded rod 505 will cause the lower pressing plate 501 to descend. When the lower pressing plate 501 drives the rubber pad 502 to press the straight pipe tightly, the user can conveniently weld the special-shaped air duct and the straight pipe.

[0039] In summary, for this special-shaped air duct fixing tooling, through the combined use of the pressing component 5, the clamping component 6, the support rod 7 and the connecting plate 8, the electric cylinder 11 is activated to drive the special-shaped plate 12 at the output end to rise. When the special-shaped plate 12 rises, the inner wall of the extrusion hole 13 will squeeze the extrusion rod 65. When the extrusion rod 65 is squeezed, it will drive the control plate 63 to move. When the control plate 63 moves, it will drive the two moving rods 62 to move. When the moving rods 62 move, they will drive the two clamping plates 61 to clamp the special-shaped air duct, solving the problem that when welding the special-shaped air duct, one person holds it by hand while the other person welds. However, holding the welding by hand depends on the manual skills and experience of the welder, which may lead to inaccurate alignment of the welding joints, thus affecting the welding quality.
