[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] As Figures 2-4 shown, a trimming and punching device for assembling automobile air-conditioning ducts includes a frame 1;

[0046] The clamping and trimming assembly 2 is installed on the frame 1 and includes a first clamping and trimming part 21 and a second clamping and trimming part 22. The above-mentioned first clamping and trimming part 21 and second clamping and trimming part 22 are respectively used for clamping both ends of the air-conditioning duct and trimming the burrs;

[0047] The punching assembly 3 is installed on the frame 1 and includes a first punching part 31, a second punching part 32, a third punching part 33 and a fourth punching part 34 for punching the air-conditioning duct;

[0048] Among them,

[0049] The first punching part 31 includes a first drill 311 that can be lifted along the frame 1, and a pressure head 312 is arranged vertically above the first drill 311. The pressure head 312 is fixed on the first clamping and trimming part 21.

[0050] The working principle and beneficial effects of the above embodiments are:

[0051] Manually place the air-conditioning duct into the clamping and trimming assembly 2, use the first clamping and trimming member 21 and the second clamping and trimming member 22 to clamp and fix both ends of the air-conditioning duct respectively and trim its burrs, and then use the punching assembly 3 to punch the air-conditioning duct in the clamped state. Punching and burr trimming of the air-conditioning duct are carried out on the same device, reducing the equipment investment cost, improving the trimming quality and punching accuracy at the same time, with a simple structure and convenient maintenance and repair;

[0052] Among them, the first punching member 31 is in a suspended state corresponding to the punching position of the air-conditioning duct. When using the first drill 311 to carry out punching operations from bottom to top, the air-conditioning duct is assisted in positioning by pressing down the pressure head 312, improving the position accuracy of the punching.

[0053] In one embodiment,

[0054] As Figure 5 shown, the first clamping and trimming member 21 includes a bracket 211 fixedly connected to the frame 1, a first trimming member installed on the bracket 211, and a first clamping member installed on the first trimming member;

[0055] Among them,

[0056] The first trimming member includes a tool holder 212 installed on the bracket 211. A first cutting tool 213 is slidably installed in the tool holder 212, and the end of the first cutting tool 213 is connected to a first cylinder 214;

[0057] The first clamping member includes a first upper profiling block 215 and a first lower profiling block 216. The first upper profiling block 215 and the first lower profiling block 216 are in contact with each other and installed at the front end of the tool holder 212. A second cylinder 217 for driving its up and down movement is connected to the upper end of the first upper profiling block 215;

[0058] A profiling cavity for accommodating the air-conditioning duct is provided between the first upper profiling block 215 and the first lower profiling block 216;

[0059] The working principle and beneficial effects of the above embodiment are:

[0060] The second cylinder 217 drives the first upper profiling block 215 to move away from the first lower profiling block 216. Manually place the air-conditioning duct into the profiling cavity of the first lower profiling block 216. At this time, the second cylinder 217 drives the first upper profiling block 216 to move down until it abuts against the first lower profiling block 216, realizing the clamping operation of the air-conditioning duct. At this time, the first cylinder 214 expands and contracts to push the first cutting tool 213 to move forward along the tool holder 212, trimming the burrs at one end of the air-conditioning duct. The design of the first upper profiling block 215 and the first lower profiling block 216 makes the process of clamping and trimming the air-conditioning duct more compact and stable;

[0061] By means of the above-mentioned automated edge trimming and punching methods, the efficiency of edge trimming and punching of air-conditioning ducts is improved, while ensuring the accuracy and safety of operations, and the production efficiency and product quality of air ducts are enhanced.

[0062] In one embodiment,

[0063] The punch head 312 is installed on the first profiling block 215, and an avoidance hole is provided at the bottom of the punch head 312 directly facing the first drill 311;

[0064] The avoidance hole allows the first drill 311 not to collide or interfere with the punch head 312 during the punching operation, making the punching operation smoother and more accurate. The auxiliary positioning function of the punch head further improves the quality and efficiency of punching.

[0065] In one embodiment,

[0066] The first punching member 31 further includes a third cylinder 313 fixedly connected to the frame 1 and a first motor 314 provided at the output end of the third cylinder 313. The output end of the first motor 314 is connected to the above-mentioned first drill 311.

[0067] The third cylinder 313 drives the first motor 314 to displace, and the first motor 314 drives the first drill 311 to rotate and punch. Through the coordinated operation of the third cylinder 313 and the first motor 314, the operation process is simplified and the punching efficiency is improved.

[0068] The design integrating the cylinder and the motor improves the automation degree of the entire punching assembly and reduces the need for manual operation.

[0069] In one embodiment,

[0070] As Figure 6 shown, the second punching member 32 includes a support 321 and a sliding table cylinder 322 horizontally installed on the support 321. The output end of the sliding table cylinder 322 is connected to a fourth cylinder 323. The output end of the fourth cylinder 323 is provided with a second motor 324, and the output end of the second motor 324 is connected to a second drill 325;

[0071] The sliding table cylinder 322 drives the fourth cylinder 323 to move and position in the horizontal direction. The fourth cylinder 323 drives the second motor 324 to angularly displace, and the second motor 324 drives the second drill 325 to perform a rotary punching operation;

[0072] The design of the sliding table cylinder 322 avoids interference with the operation of the second clamping and edge trimming member 22. By combining the sliding table cylinder 322, the fourth cylinder 323 and the second drill 325, precise control and flexible positioning of the punching operation are achieved, with a high degree of automation and a reduced need for manual operation.

[0073] In one embodiment,

[0074] As Figures 7-8 shown, the second clamping and trimming member 22 includes a base 221 fixedly connected to the frame 1, a second trimming member mounted on the base 221, and a second clamping member mounted on the second trimming member;

[0075] Wherein,

[0076] The second trimming member includes a tool plate 222 mounted on the base 221. A second cutter 223 is slidably mounted on the tool plate 222. The end of the second cutter 223 is connected to a fifth cylinder 224. A blanking groove is formed on the tool plate 222 for the dropping of the trimmed air-conditioning track;

[0077] The second clamping member includes a second profiling block 225 and a second lower profiling block 226. The second profiling block 225 and the second lower profiling block 226 are in contact with each other and mounted at the front end of the tool plate 222. A sixth cylinder 227 for driving its up and down movement is connected to the upper end of the second profiling block 225;

[0078] The sixth cylinder 227 drives the second profiling block 225 to move away from the second lower profiling block 226. An operator places the air-conditioning duct into the profiling cavity of the second lower profiling block 226. The sixth cylinder 227 drives the second profiling block 225 to move down until it abuts against the second lower profiling block 226, realizing the clamping operation of the air-conditioning duct. The fifth cylinder 224 expands and contracts to push the second cutter 223 to move forward along the tool plate 222, cutting off the burrs at the other end of the air-conditioning duct. The cut burrs fall through the blanking groove;

[0079] The design of the second profiling block 225 and the second lower profiling block 226 makes the clamping and trimming process more compact and stable. The design of the blanking groove facilitates the collection and treatment of trimming waste, keeping the working environment clean.

[0080] In one embodiment,

[0081] Avoidance grooves for the operation of the second drill 325 are formed on both the second profiling block 225 and the second lower profiling block 226;

[0082] When the second drill 325 needs to perform a drilling operation on the air-conditioning duct, the avoidance grooves on the second profiling block 225 and the second lower profiling block 226 allow the drill to pass freely without being hindered; ensuring the accuracy of the drilling position and avoiding drilling deviation caused by improper avoidance.

[0083] It should be noted that,

[0084] The structures of the third punching member 33 and the fourth punching member 34 are similar to that of the first punching member 31. When installed on the frame 1, they are adapted to the positions of the air-conditioning ducts to be punched. At the same time, the third punching member 33 and the fourth punching member 34 are correspondingly provided with guiding grooves on the second clamping member to ensure the accuracy of the punching positions of the air-conditioning ducts.

[0085] In summary, the trimming and punching device for assembling automobile air-conditioning ducts of the present utility model performs automatic trimming and punching, improving the efficiency of trimming and punching of air-conditioning ducts. At the same time, it ensures the accuracy and safety of the operation, and improves the production efficiency and product quality of the air ducts.
