[0002] Aluminum profile refers to aluminum alloy profile, which is the most widely used type of non-ferrous metal structural material in industry.

[0004] Although the device can easily twist the aluminum profile into the required bending degree, and the staff does not need to apply any force to it during the operation, thereby improving the practicality of the device, the device cannot quickly adjust the clamping position according to the twisted position of the aluminum profile, which reduces the applicability of the device. At the same time, it is also impossible to easily replace the fixing seat according to the shape of the aluminum profile, which reduces the use effect of the device. For this reason, we provide a rotary precision CNC twisting device to solve the above problems. Utility Model Content

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0021] Refer toFigure 1 and Figure 2 A rotary precision numerical control twisting device, comprising a housing 1, an adjusting mechanism 2 is arranged above the housing 1. The adjusting mechanism 2 includes a threaded rod 201. The threaded rod 201 is rotatably connected to the inside of the housing 1. An auxiliary bearing 212 is sleeved on the outer surface of the threaded rod 201. The auxiliary bearing 212 is embedded in the inside of the housing 1. The auxiliary bearing 212 can reduce the friction generated when the threaded rod 201 rotates, make the threaded rod 201 more sensitive when rotating, and at the same time can also reduce the wear of the threaded rod 201 when rotating, and increase the service life of the threaded rod 201.

[0022] Referring to Figure 2 , a moving block 202 is threadedly connected to the outer surface of the threaded rod 201. The moving block 202 is slidably connected to the inside of the housing 1. Two limiting blocks 213 are fixedly connected to the inner top wall of the moving block 202. Each limiting block 213 is slidably connected to the inside of the housing 1. The limiting block 213 can move simultaneously with the moving block 202, and use the friction generated by itself when moving against the housing 1 to improve the stability of the moving block 202, and improve the stability of the device.

[0023] Referring to Figure 3 and Figure 4 , an auxiliary block 203 is fixedly connected to the upper surface of the moving block 202. A connecting block 214 is fixedly connected to the upper surface of the housing 1. An auxiliary frame 215 and a stabilizing frame 218 are respectively fixedly connected to the upper surface of the connecting block 214. A rotating motor 216 is fixedly connected to the upper surface of the auxiliary frame 215. The output end of the power of the rotating motor 216 is fixedly connected to a transmission rod 217. The right end of the transmission rod 217 penetrates through the stabilizing frame 218 and is fixedly connected to the left side surface of the clamping block 204. The power generated by the rotating motor 216 is used to drive the transmission rod 217 to rotate, and then the clamping block 204 rotates, so as to twist and correct the clamped aluminum sheet. The auxiliary frame 215 can play a role in supporting the rotating motor 216.

[0024] Referring to Figure 4 , a rotating bearing 219 is sleeved on the outer surface of the transmission rod 217. The rotating bearing 219 is embedded in the inside of the auxiliary frame 215. By the cooperation of the rotating bearing 219 and the auxiliary frame 215, the supporting position of the transmission rod 217 can be increased, and at the same time the sensitivity of the transmission rod 217 when rotating can also be improved, and the effect of the device when in use is increased.

[0025] Referring to Figure 4, a reinforcing ring 220 is fixedly connected to the outer surface of the transmission rod 217. The right end of the reinforcing ring 220 is fixedly connected to the left side surface of the clamping block 204. The reinforcing ring 220 can increase the fixed connection area between the transmission rod 217 and the clamping block 204, thereby improving the firmness of the bidirectional connection relationship, avoiding the possibility of breakage during long-term use, and increasing the durability of the device.

[0026] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A clamping block 204 is arranged above the housing 1. Two fixing blocks 205 are arranged inside both the clamping block 204 and the auxiliary block 203. An upper clamping block 207 and a lower clamping block 206 are threadedly connected inside each group of fixing blocks 205. A servo motor 208 is fixedly connected to the left side surface of the housing 1. The power output end of the servo motor 208 is fixedly connected to the left end of the threaded rod 201. Electric telescopic rods 209 are fixedly connected to the upper surfaces of both the clamping block 204 and the auxiliary block 203. The telescopic ends of the two electric telescopic rods 209 respectively penetrate through the clamping block 204 and the auxiliary block 203 and are fixedly connected to the upper surface of one of the fixing blocks 205. Mounting blocks 210 are fixedly connected to the front and back surfaces of each group of upper clamping blocks 207 and lower clamping blocks 206. A fixing bolt 211 is slidably connected inside each group of mounting blocks 210. The mutually remote ends of each group of fixing bolts 211 respectively penetrate through the mounting blocks 210 and are threadedly connected to the fixing blocks 205. The bottom surfaces of one group of fixing blocks 205 are respectively fixedly connected to the inner bottom walls of the clamping block 204 and the auxiliary block 203. The servo motor 208 can provide power for the threaded rod 201 to rotate, so that the moving block 202 moves inside the housing 1. The electric telescopic rod 209 can play a role in pushing the upper clamping block 207, thereby clamping the aluminum plate.

[0027] Working principle: When in use, first connect the servo motor 208, the electric telescopic rod 209 and the rotating motor 216 to the power supply. When it is necessary to correct the aluminum sheet, place both ends of the aluminum sheet on the surface of the upper clamping block 207 inside the auxiliary block 203 and the clamping block 204. Then start the electric telescopic rod 209. Relying on the power generated by the electric telescopic rod 209, push the fixed block 205 and the upper clamping block 207 to move downward and contact the aluminum sheet to clamp it. Then start the rotating motor 216. Use the power generated by the rotating motor 216 to drive the transmission rod 217 to rotate. The rotating bearing 219 can improve the effect of the transmission rod 217 during rotation, and then make the clamping block 204 rotate, so as to twist and correct the mechanical energy of the aluminum sheet. When it is necessary to adjust the clamping length, start the servo motor 208, and then make the threaded rod 201 rotate forward or backward. The auxiliary bearing 212 can improve the stability of the threaded rod 201 during rotation, and then make the moving block 202 move left and right inside the housing 1, so as to drive the auxiliary block 203 to move simultaneously, changing the positions of one set of upper clamping block 207 and lower clamping block 206, achieving the ability to quickly adjust the clamping length. When it is necessary to replace the clamping tools of different sizes, rotate the fixing bolts 211 to remove them from the inside of the fixed block 205, the upper clamping block 207 and the lower clamping block 206 respectively. At this time, the upper clamping block 207 and the lower clamping block 206 can be taken out, and the appropriate clamping tool can be fixed through the fixing bolts 211, which not only increases the use effect of the rotary precision numerical control twisting device, but also improves the applicability of the rotary precision numerical control twisting device.
