Description

Technical Field

[0001] The present invention relates to the technical field of automotive part manufacturing, specifically to a cutting device for automotive part manufacturing and its usage method. Background Art

[0002] In the manufacturing process of automotive parts such as automotive exhaust pipes and intake pipes, it is usually necessary to use a laser pipe cutting machine to cut pipes into required sizes. Currently, during the cutting process of a laser pipe cutting machine, one end of the pipe is fixed by a main chuck, and then the pipe is cut by a laser cutting head.

[0003] Currently, when cutting a long pipe with a laser pipe cutting machine, since the main chuck can only fix one end of the cutting section of the pipe, during the high-speed rotary cutting process, the cutting section of the pipe will be affected by the centrifugal force generated by the rotation, resulting in a position deviation of the cutting section of the pipe. This deviation phenomenon will make the distance between the laser cutting head and the pipe uneven, and the laser cannot be accurately focused on the predetermined cutting position. In this way, the laser beam will deviate from the predetermined cutting line, making the pipe cutting machine unable to ensure the cutting accuracy, and will also cause irregular serrated burrs at the cutting end, seriously affecting the assembly accuracy of the pipe. In addition, when the pipe is cut by half, the connection strength of the pipe will be significantly reduced. Under the condition of high-speed rotation, the loosening of one end will cause obvious shaking of the cutting section of the pipe during rotation, which will also make the laser beam deviate from the predetermined cutting line, thereby affecting the cutting accuracy.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The cutting equipment and its usage method for manufacturing automotive parts are provided with a pipe component, a stable clamping component group, and a driving component group. Currently, when a laser pipe cutting machine cuts a long pipe, since the main chuck can only fix one end of the cutting section of the pipe, during the high-speed rotary cutting process, the cutting section of the pipe will be affected by the centrifugal force generated by the rotation, resulting in the displacement of the cutting section of the pipe. This displacement phenomenon will make the distance between the laser cutting head and the pipe uneven, and the laser cannot be accurately focused on the predetermined cutting position. In this way, the laser beam will deviate from the predetermined cutting line, making the pipe cutting machine unable to ensure the cutting accuracy, and will also cause irregular serrated burrs at the cutting end, seriously affecting the assembly accuracy of the pipe. In the designed stable clamping component group, during use, the pipe will be transported to the inside of the stable clamping component group by an external structure. After the transportation is completed, the control motor 1 is started. The motor 1 drives the synchronous gear part 1 to rotate through its working end. The rotation of the synchronous gear part 1 drives the synchronous gear part 2 and the gear 1 to rotate through the synchronous belt 1. The tensioning wheel is used to let the synchronous belt 1 avoid the running position of the synchronous moving plate. The rotation of the gear 1 drives the driven disk to rotate through the intermediate gear part 1. The rotation of the driven disk drives the bevel gear part to rotate through the semi-circular bevel gear. The bevel gear part drives the threaded rod. The rotation of the threaded rod can move the moving strip through the threaded belt, and then move the position of the side moving plate. The side moving plate drives the synchronous moving plate, and the synchronous moving plate makes the two side moving plates move synchronously in the opposite direction through the rack bar and the intermediate gear part 2. Then, the pipe component is clamped by the movement of the armrest and the clamping roller. When the pipe component is clamped, it can still be driven by an external machine to move back and forth on the clamping roller. The design of this stable clamping component group, compared with the current clamping structure, completes the clamping through a mechanical structure, and the synchronous effect is better. The four groups of clamping rollers can clamp a longer distance of the pipe component compared with the current clamping, thereby improving the clamping stability, avoiding the displacement of the pipe component during rotation, and enabling the laser beam to accurately cut the pipe component according to the predetermined cutting line, effectively improving the cutting quality of the overall laser pipe cutting machine;

[0015] 2. The cutting equipment and its usage method for manufacturing automotive parts are provided with a stable clamping component group and a driving component group. The designed stable clamping component group ensures the accuracy of the laser beam cutting while being accurate in cutting and not easily generating serrated burrs, thus not affecting the assembly of the pipe after cutting. And the design of the driving component group, by starting the motor 2, the motor 2 drives the gear 2 to rotate through its working end. The gear 2 drives the gear 3 to rotate, and the gear 3 drives the rear housing sleeve to rotate. The rotation of the rear housing sleeve can drive the rotation of the overall stable clamping component group. The overall stable clamping component group is connected through bearings, the front frame plate, and the rear frame plate. The rotation of the stable clamping component group can naturally drive the rotation of the pipe component. During laser cutting, the rotation of the pipe component can be effectively completed through the driving component group to ensure the normal operation of the cutting;

[0016] 3. The cutting equipment and its usage method for manufacturing automotive parts are provided with an auxiliary support component group. When the pipe is cut by more than half, the connection strength of the pipe will be significantly reduced. In the case of high-speed rotation, the loosening of one end will cause obvious shaking of the cut pipe section during rotation, which will also cause the laser beam to deviate from the predetermined cutting line, thus affecting the cutting accuracy. In the corresponding design of the auxiliary support component group, by controlling the third motor, the working end of the third motor drives the rotation of the control rod through the pulley assembly. The rod drives the lead screw, and the lead screw can drive the moving base to slide on the base through the nut pair. By this control, the moving base is adjusted to the vertical bottom of the cutting position of the pipe part. The height of the inner moving part is adjusted by the telescopic pneumatic expansion rod. The height adjustment of the inner moving part can make the V-shaped part, sphere, connecting rod, air chamber cylinder, piston part and outer plate adaptively adjust the height of the pipe part. By pumping air into or out of the air chamber cylinder through the air pump, the position of the piston part inside the air chamber cylinder can be controlled. When inflating, the piston part will be pushed to both sides of the air chamber cylinder. The movement of the piston part will drive the change of the position of the V-shaped part through the connecting rod. Through this design, the sphere can contact the pipe part and can adapt to different sizes of pipe parts. During cutting, the laser cutting head does not move, and the pipe part is driven by the driving component group and the stable clamping component group to rotate. Therefore, the cutting position of the pipe part will be in the opposite position to the auxiliary support component group, and the auxiliary support component group will not affect the laser cutting. In addition, the sphere contacts the V-shaped part on both sides of the cutting position. When the structural strength of the pipe part is insufficient after being cut by more than half, the auxiliary support component group can form a support on both sides of the cutting position, avoiding the shaking caused by insufficient structural strength, and thus avoiding the deviation of the laser beam from the cutting line, improving the overall cutting accuracy.

[0042] Working principle: When the current laser pipe cutting machine cuts long pipes, since the main chuck can only fix one end of the cutting section of the pipe, during the high-speed rotary cutting process, the cutting section of the pipe will be affected by the centrifugal force generated by the rotation, resulting in the position deviation of the cutting section of the pipe. This deviation phenomenon will make the distance between the laser cutting head and the pipe uneven, and the laser cannot be accurately focused on the predetermined cutting position. In this way, the laser beam will deviate from the predetermined cutting line, making the pipe cutting machine unable to ensure the cutting accuracy, and will also cause irregular serrated burrs at the cutting end, seriously affecting the assembly accuracy of the pipe. In the corresponding designed stable clamping component group 200, during use, the pipe will be transported to the inside of the stable clamping component group 200 by an external structure. After the transportation is completed, the control motor 1 201 is started. The motor 1 201 drives the synchronous gear part 1 202 to rotate through the working end. The rotation of the synchronous gear part 1 202 drives the synchronous gear part 2 205 and the gear 1 206 to rotate through the synchronous belt 1 203. The tensioning wheel 204 is used to let the synchronous belt 1 203 avoid the running position of the synchronous moving plate 214. The rotation of the gear 1 206 drives the driven disk 209 to rotate through the intermediate gear part 1 208. The rotation of the driven disk 209 drives the bevel gear part 210 to rotate through the semi-circular bevel gear. The bevel gear part 210 drives the threaded rod 211. The rotation of the threaded rod 211 can move the moving strip 212 through the threaded belt, and then move the position of the side moving plate 213. The side moving plate 213 drives the synchronous moving plate 214. The synchronous moving plate 214 makes the two side moving plates 213 move synchronously in the opposite direction through the rack bar 215 and the intermediate gear part 2 216, and then clamps the pipe part 100 through the movement of the armrest 217 and the clamping roller 218. When the pipe part 100 is clamped, it can still be driven by an external machine to move back and forth on the clamping roller 218. The design of this stable clamping component group 200, compared with the current clamping structure, completes the clamping through a mechanical structure, and the synchronization effect is better. The four groups of clamping rollers 218 can clamp the pipe part 100 for a longer distance compared with the current clamping, thereby improving the clamping stability, avoiding the position deviation when the pipe part 100 rotates, and enabling the laser beam to accurately cut the pipe part 100 according to the predetermined cutting line, effectively improving the cutting quality of the overall laser pipe cutting machine.The designed stable clamping component group 200 ensures the accuracy of laser beam cutting while making the cutting accurate and not easily generating serrated burrs, thus not affecting the assembly of the pipe after cutting. Moreover, in the design of the driving component group 300, it is started by the second motor 301. The second motor 301 drives the second gear 305 to rotate through its working end. The second gear 305 drives the third gear 306 to rotate. The third gear 306 then drives the rear housing sleeve 220 to rotate. The rotation of the rear housing sleeve 220 can drive the rotation of the overall stable clamping component group 200. The overall stable clamping component group 200 is connected to the front frame plate 308 and the rear frame plate 307 through bearings. The rotation of the stable clamping component group 200 can naturally drive the rotation of the pipe component 100. During laser cutting, the rotation of the pipe component 100 can be effectively completed through the driving component group 300 to ensure the normal operation of the cutting. When the pipe is cut by half, the connection strength of the pipe will be significantly reduced. In the case of high-speed rotation, the loosening of one end will cause obvious shaking of the cut pipe section during rotation, which will also cause the laser beam to deviate from the predetermined cutting line, thus affecting the cutting accuracy. In the corresponding designed auxiliary support component group 400, by controlling the third motor 401, the working end of the third motor 401 drives the control rod 403 to rotate through the pulley assembly 402. The rod 403 drives the lead screw 404. The lead screw 404 can drive the moving base 405 to slide on the base 304 through the nut pair. Through this control, the moving base 405 is adjusted to the vertical bottom of the cutting position of the pipe component 100. The height of the inner moving part 408 is adjusted through the telescopic pneumatic telescopic rod 407. The height adjustment of the inner moving part 408 can enable the V-shaped part 410, the sphere 411, the connecting rod 412, the air chamber cylinder 413, the piston part 414, and the outer plate 409 to adaptively adjust the height of the pipe component 100. By pumping air into or out of the air chamber cylinder 413 through the air pump, the position of the piston part 414 inside the air chamber cylinder 413 can be controlled. When inflating, the piston part 414 will be pushed to both sides of the air chamber cylinder 413. The movement of the piston part 414 will drive the position change of the V-shaped part 410 through the connecting rod 412. Through this design, the sphere 411 can contact the pipe component 100 and can adapt to different sizes of the pipe component 100. During cutting, the laser cutting head does not move and the pipe component 100 is driven to rotate by the driving component group 300 and the stable clamping component group 200. Therefore, the cut position of the pipe component 100 will be in the opposite position to the auxiliary support component group 400. The auxiliary support component group 400 will not affect the laser cutting. In addition, the sphere 411 contacts the V-shaped part 410 on both sides of the cutting position. When the structural strength of the pipe component 100 is insufficient after being cut by half, the auxiliary support component group 400 can form supports on both sides of the cutting position to avoid the shaking caused by insufficient structural strength, thereby avoiding the deviation of the laser beam from the cutting line and improving the overall cutting accuracy.
