[0002] Air conditioning connection pipes refer to the connecting pipe system between the indoor and outdoor units of an air conditioner. Currently, most domestic companies use copper pipes, whose main function is to transport refrigerant to achieve the cooling and heating effects of the air conditioner.

[0003] Air conditioning connecting pipes play a crucial role in air conditioning systems. They are the pipes through which refrigerant circulates, and their quality directly affects the cooling effect and overall performance of the air conditioner. The refrigerant circulates in the connecting pipes, enabling heat exchange between indoor and outdoor environments and ensuring the normal operation of the air conditioner. The production of air conditioning connecting pipes requires a crimping machine to tightly connect the metal fittings to the connecting pipes. However, when using existing crimping machines, different specifications of air conditioning connecting pipes are placed between the crimping blocks, requiring manual support before starting the crimping machine, resulting in low crimping efficiency.

[0014] 2. By adjusting the connection between the throttle and the worm, and the connection between the fixed shaft and the worm wheel, rotating the throttle drives the worm to rotate, which in turn drives the worm wheel to rotate on the surface of the fixed shaft. Then, through the connection between the connecting rod and the connecting frame, and the connection between the connecting frame and the machine base, the rotation of the worm wheel drives the connecting rod and the connecting frame to rotate, thereby changing the working direction of the machine base. This improves the applicability of the crimping machine and achieves the effect of adjusting the working direction of the crimping machine. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A crimping machine for producing air conditioning connecting pipes includes a base 1 for supporting the entire equipment. An electrical control system 11 is installed on the surface of the base 1 to control the start of a crimping machine 12. The crimping machine 12 is installed on the surface of the base 1 for crimping air conditioning copper pipes 13. The air conditioning copper pipes 13 are inserted into the surface of the crimping machine 12. A support frame 2 is fixedly connected to the surface of the base 1 for clamping the air conditioning copper pipes 13. A cylinder 21 is installed on the surface of the support frame 2 for moving a rack plate 22. The rack plate 22 is fixedly connected to the surface of the cylinder 21 for rotating a first driven rack plate 23 and a second driven rack plate 26. The first driven rack plate 23 is meshed with the surface of the rack plate 22 for rotating a connecting frame 35. A first balance rod 24 is rotatably connected to the surface of the support frame 2 for balancing the movement of a first clamping block 25. The end of the first driven rack plate 23 away from the support frame 2 is movably connected to the first clamping block 25 for cooperating with the first... Two clamping blocks 28 clamp the air conditioning copper pipe 13. A second driven toothed plate 26 is meshed with the surface of the rack plate 22, which drives the second clamping block 28 to move by rotating itself. A second balance rod 27 is rotatably connected to the surface of the support frame 2, which is used to balance the movement of the second clamping block 28. The second clamping block 28 is movably connected to the end of the second driven toothed plate 26 away from the support frame 2, which is used to cooperate with the first clamping block 25 to clamp the air conditioning copper pipe 13. An adjusting handle 3 is rotatably connected to the surface of the base 1, which is used to drive the worm 31 to rotate. The worm 31 is fixedly connected to the surface of the adjusting handle 3, which is used to drive the worm wheel 33 to rotate. A fixed shaft 32 is fixedly connected inside the base 1, which is used to rotate the worm wheel 33. The worm wheel 33 is meshed with the surface of the worm 31, which is used to drive the connecting rod 34 to rotate. The connecting rod 34 is fixedly connected to the surface of the worm wheel 33, which is used to connect the connecting frame 35. The connecting frame 35 is fixedly connected to the end of the connecting rod 34 away from the worm wheel 33, which is used to adjust the working direction of the pipe crimping machine 12.

[0024] Furthermore, the surface of the support frame 2 is provided with multiple sets of circular grooves for connecting the first driven toothed plate 23, the first balance rod 24, the second driven toothed plate 26, and the second balance rod 27. The rack plate 22 is movably connected to the surface of the base 1 via the cylinder 21. The first driven toothed plate 23 is rotatably connected to the surface of the support frame 2 via the rack plate 22. The second driven toothed plate 26 is rotatably connected to the surface of the support frame 2 via the rack plate 22. Activating the cylinder 21 causes the rack plate 22 to move, thereby driving the first driven toothed plate 23 and the second driven toothed plate 26 to rotate on the surface of the support frame 2.

[0025] Furthermore, the two ends of the first driven toothed plate 23 are rotatably connected to the surfaces of the support frame 2 and the first clamping block 25, and the two ends of the first balance rotating rod 24 are rotatably connected to the surfaces of the support frame 2 and the first clamping block 25. The first clamping block 25 is movably connected to the surface of the support frame 2 through the first driven toothed plate 23, and the first balance rotating rod 24 is rotatably connected to the surface of the support frame 2 through the first clamping block 25. The rotation of the first driven toothed plate 23 drives the first clamping block 25 to move, and the synchronous rotation of the first balance rotating rod 24 causes the first clamping block 25 to move horizontally.

[0026] Furthermore, the two ends of the second driven toothed plate 26 are rotatably connected to the surfaces of the support frame 2 and the first clamping block 25, the two ends of the second balance rotating rod 27 are rotatably connected to the surfaces of the support frame 2 and the first clamping block 25, the second clamping block 28 is movably connected to the surface of the support frame 2 via the second driven toothed plate 26, and the second balance rotating rod 27 is rotatably connected to the surface of the support frame 2 via the second clamping block 28. The rotation of the second driven toothed plate 26 drives the second clamping block 28 to move, and the synchronous rotation of the second balance rotating rod 27 causes the second clamping block 28 to move horizontally.

[0027] Furthermore, the air conditioning copper pipe 13 acts between the first clamping block 25 and the second clamping block 28. The air conditioning copper pipe 13 is connected by the abutting of the surfaces of the first clamping block 25 and the second clamping block 28. The air conditioning copper pipe 13 is fixedly connected to the surface of the crimping machine 12 by the second clamping block 28. After the air conditioning copper pipe 13 is inserted into the surface of the crimping machine 12, the first clamping block 25 and the second clamping block 28 clamp the air conditioning copper pipe 13 by starting the cylinder 21, causing the air conditioning copper pipe 13 to fall or shake.

[0028] Furthermore, the worm 31 is internally rotatably connected to the base 1 via the adjusting handle 3, and the worm wheel 33 is rotatably connected to the surface of the fixed shaft 32 via the worm 31. The two ends of the connecting rod 34 are fixedly connected to the surface of the worm wheel 33 and the connecting frame 35. Rotating the adjusting handle 3 can drive the worm 31 to rotate, thereby driving the worm wheel 33 and the connecting rod 34 to rotate on the surface of the fixed shaft 32. The worm 31 and the worm wheel 33 can self-lock.

[0029] Furthermore, the connecting rod 34 is rotatably connected to the surface of the base 1 via the worm gear 33, and the connecting frame 35 is rotatably connected to the surface of the base 1 via the connecting rod 34. The crimping machine 12 is fixedly connected to the surface of the connecting frame 35 via bolts. The crimping machine 12 is rotatably connected to the surface of the base 1 via the connecting frame 35. The rotation of the connecting rod 34 drives the connecting frame 35 to rotate, thereby changing the direction of action of the crimping machine 12, which facilitates the insertion of air conditioning copper pipes 13 of different specifications.

[0030] Working principle: When using the crimping machine 12, the air conditioning copper pipe 13 is first inserted into the surface of the crimping machine 12. Then, the cylinder 21 is activated to move the rack plate 22, which in turn causes the first driven rack plate 23 and the second driven rack plate 26 to rotate on the surface of the support frame 2. This causes the first clamping block 25 and the second clamping block 28 to move closer to the air conditioning copper pipe 13 until the air conditioning copper pipe 13 is clamped and fixed. The second driven rack plate 26 and the second balance rod 27 rotate along with the movement of the first clamping block 25 and the second clamping block 28. The movement causes the first clamping block 25 and the second clamping block 28 to move horizontally and fix the air conditioning copper pipe 13. Then, the electrical control system 11 can be started to make the crimping machine 12 crimp the air conditioning copper pipe 13. If the air conditioning copper pipe 13 is too long and inconvenient to insert, the worm gear 31 can be rotated by rotating the adjustment handle 3, so that the worm wheel 33 and the connecting rod 34 rotate on the surface of the fixed shaft 32, thereby driving the connecting frame 35 and the crimping machine 12 to rotate, changing the direction of action of the crimping machine 12, making it easier to insert the air conditioning copper pipe 13.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
