[0003] When using a traditional cutting device, the cutting part of the device is often fixed directly to the device operating table by bolts to keep its position constant. Therefore, if the cutting blade is stuck by the material or encounters excessive resistance during the cutting process, a rebound force may be generated, causing the cutting blade to move suddenly upward or in other directions, causing harm to the operator, and the practicality is poor; In the process of cutting aluminum alloy profiles, since the cutting part of the equipment is fixed in the operating table with bolts, when it is necessary to cut aluminum alloy profiles of different sizes, since the vertical position of the cutting blade is constant, it is necessary to remove the bolts to adjust the position of the cutting part or replace the cutting blades of different radius, which makes the operation process cumbersome and inflexible; In the process of cutting aluminum alloy profiles, the operator is required to carry multiple aluminum alloy profiles to the operating table and align their ends with the clamps on the equipment.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figure 4 and Figure 6-Figure 9As shown, an automobile spare parts cutting device described in the present invention includes a cutting machine body 1, a conveying structure 2 installed on the cutting machine body 1, a feeding structure 3 installed on the cutting machine body 1, a braking structure 5 arranged inside the cutting machine body 1, a height adjustment structure 6 connected to the braking structure 5, and a cutting structure 7 arranged on the height adjustment structure 6, wherein the braking structure 5 includes six load-bearing beams 501 and two guide plates 502 fixedly connected between two of the load-bearing beams 501, three load-bearing beams 501 are fixedly connected to the inner walls of both sides of the cutting machine body 1, a support plate 504 is slidably connected between the two guide plates 502, two third guide rods 507 are fixedly connected between the three load-bearing beams 501 on the same side, a docking block 508 is slidably connected between the two third guide rods 507, the docking block 508 is slidably connected to the outer wall of the guide plate 502, and two clamping blocks 509 are slidably connected inside the docking block 508, one of which A spring 511 is fixedly connected between the inner wall of the clamping block 509 and the docking block 508, a pull rod 510 is fixedly connected between the ends of the two clamping blocks 509, and the pull rod 510 is slidably connected to the docking block 508. The other ends of the two clamping blocks 509 are mutually engaged with the grooves provided on the support plate 504, and the support plate 504 is connected with a height adjustment structure 6, and the height adjustment structure 6 is matched with a cutting structure 7. The interiors of the two guide plates 502 are fixedly connected with a second guide rod 5 03, the support plate 504 is slidably connected to the second guide rod 503, both ends of the support plate 504 are fixedly connected to the inner wall of the guide plate 502 with tension springs 505, the bottoms of the two guide plates 502 are fixedly connected to limit blocks 506, the two load-bearing beams 501 close to the guide plates 502 are rotatably connected to the second screw rod 512, the docking block 508 is threadedly connected to the second screw rod 512, and the bottom of the second screw rod 512 is fixedly connected to a knob 513;During the cutting process, if it is found that the saw blade 704 is stuck by the aluminum alloy profile 4 or receives too much resistance and other abnormal phenomena, in order to avoid damage to the saw blade 704 or fragments flying around, it is only necessary to quickly pull the pull rod 510 on the side of the cutting machine body 1, and then the pull rod 510 drives the two blocks 509 inside the docking block 508 to slide outward, and at the same time one of the blocks 509 compresses the spring 511 until the two blocks 509 are no longer engaged with the grooves provided on the support plate 504. At this time, the support plate 504 and the mounting plate 508 are The cutting part installed above it moves downward rapidly under the action of gravity and the tension of the tension spring 505, so that the saw blade 704 moves downward rapidly until it is completely retracted into the interior of the cutting machine body 1. At the same time, since the support plate 504 slides downward along the guide plate 502 and the second guide rod 503 at the same time, the stability of the overall movement process is guaranteed. When the support plate 504 slides downward until the bottom hits the two limit blocks 506, the two tension springs 505 first restore to their initial lengths, and the support plate 504 and the cutting part of the device will continue to move downward under the action of inertia, and at this time the tension spring 505 will be compressed, so that the tension spring 505 plays a buffering role. At the same time, the limit block 506 installed at the bottom of the guide plate 502 is made of rubber material, which can prevent the support plate 504 and the cutting part of the device from continuing to slide downward, and at the same time plays a buffering effect, which is highly practical. At this time, the saw blade 704 is effectively retracted to the internal space of the cutting machine body 1, avoiding the damage caused by the saw blade 704 continuing to cut, thereby improving safety. At the same time, when the pull rod 510 is not pulled, Since the docking block 508 and the second screw rod 512 are threadedly connected, the second screw rod 512 can be driven to rotate on the load-bearing beam 501 by turning the knob 513, so that the second screw rod 512 drives the docking block 508 and the support plate 504 to move upward, and the support plate 504 drives the second hydraulic rod 603 and the two drive racks 601 to move upward, and the two drive racks 601 drive the cutting part of the equipment to move upward, so that it is easy to adjust the height of the second hydraulic rod 603 and the cutting part as a whole, which is easy to operate and has strong flexibility. ;

[0023] Specifically, Figure 4 and Figure 6-Figure 8As shown, the height adjustment structure 6 includes two driving frames 601 and two load-bearing bars 602 fixedly connected to the driving frames 601. The driving frames 601 are slidably connected between the two third guide rods 507 located on the same side. A second hydraulic rod 603 is provided at the bottom of one of the driving frames 601. The second hydraulic rod 603 is fixedly connected to the support plate 504. The telescopic end of the second hydraulic rod 603 is fixedly connected to an adjacent driving frame 601. The two driving frames 601 are symmetrically arranged. A cutting structure 7 is installed between the two load-bearing bars 602. Before using the equipment, first The height of the saw blade 704 is adjusted according to the size of the aluminum alloy profile 4 to be cut. When a larger aluminum alloy profile 4 needs to be cut, the height of the saw blade 704 needs to be raised. Just turn on the power of the equipment, and the telescopic end of the second hydraulic rod 603 extends upward, thereby driving the two drive frames 601 to slide upward along the third guide rod 507. The two drive frames 601 drive the two load-bearing bars 602 and the saw blade 704 arranged above them to move upward. At this time, the height of the saw blade 704 extending outward on the cutting machine body 1 is effectively increased, which is convenient for cutting aluminum alloy profiles 4 of different sizes. It is easy to operate and has strong flexibility.

[0024] Specifically, Figure 4 and Figure 6-Figure 8As shown, the cutting structure 7 includes a second guide rail 701 and two sliders 702 slidably connected to the second guide rail 701, each of the two load-bearing bars 602 is fixedly connected to a second guide rail 701, a mounting seat 703 is fixedly connected between the four sliders 702, an end of the load-bearing bar 602 away from the second hydraulic rod 603 is fixedly connected to a third motor 705, a third screw rod 706 is fixedly connected to the output shaft of the third motor 705, and an end of the third screw rod 706 away from the third motor 705 is connected to the adjacent drive frame 60 1, the mounting seat 703 is threadedly connected to the third screw rod 706, the upper surface of the mounting seat 703 is fixedly connected to a reducer 707, one end of the output shaft of the reducer 707 is installed with a third pulley 710, and the other end is installed with a saw blade 704, the bottom of the mounting seat 703 is fixedly connected to a fourth motor 708, the output shaft of the fourth motor 708 is fixedly connected to a second pulley 709, and a second belt 711 is wound between the second pulley 709 and the third pulley 710, and the mounting seat 703 is The "U"-shaped structure has a radius of the second pulley 709 that is larger than the radius of the third pulley 710. During the cutting process, the third motor 705 installed at the end of the load-bearing bar 602 drives the third screw rod 706 to rotate. Since the bottom surface of the mounting seat 703 is slidably connected to the second guide rail 701 through four sliders 702, and the mounting seat 703 and the third screw rod 706 are threadedly connected, the third screw rod 706 drives the mounting seat 703 to move back and forth along the second guide rail 701, so that the mounting seat 703 drives the saw blade 704 arranged above it to move back and forth. The fourth motor 708 at the bottom of the mounting seat 703 drives the second pulley 709 on the output shaft to rotate, and the second pulley 709 drives the third pulley 710 installed on the reducer 707 to rotate through the second belt 711, so that the third pulley 710 drives the rotating shaft of the reducer 707 and the saw blade 704 at the other end of the rotating shaft to rotate, and the mounting seat 703 moves back and forth, thereby completing the cutting of the aluminum alloy profile 4, which is easy to operate and has high cutting efficiency.

[0025] Specifically, Figure 1-Figure 3As shown, the conveying structure 2 includes two first guide rails 201 and a slide plate 202 slidably connected between the two first guide rails 201, the upper surface of the cutting machine body 1 is fixedly connected with the first guide rails 201, the bottom of the slide plate 202 is fixedly connected with a connecting plate 203, the outer wall of the cutting machine body 1 is fixedly connected with a first motor 204, the cutting machine body 1 is rotatably connected with a first screw rod 205, the end of the first screw rod 205 is fixedly connected to the output shaft of the first motor 204, the connecting plate 203 is threadedly connected to the first screw rod 205, and two first support frames 206 are fixedly connected to the slide plate 202, and the upper surface of the first support frame 206 is fixedly connected with a first A hydraulic cylinder 208, a pressure plate 209 is fixedly connected to the output shaft of the first hydraulic cylinder 208, and a first guide rod 207 is fixedly connected to both ends of the pressure plate 209, and the first guide rod 207 is slidably connected to the first support frame 206, and the upper surface of the slide plate 202 is provided with an aluminum alloy profile 4, and the bottom surface of the pressure plate 209 abuts against the aluminum alloy profile 4, and the side of the first support frame 206 is fixedly connected to a mounting plate 210, and the inner side of the mounting plate 210 is fixedly connected to the second hydraulic cylinder 211, and the output shaft of the second hydraulic cylinder 211 is fixedly connected to a positioning plate 212; when the aluminum alloy profile 4 on the connecting frame 301 is transported to the cutting machine body 1, the slide plate at this time The two first support frames 206 on 202 are located at one end of the cutting machine body 1 close to the connecting frame 301. When the conveying roller 303 drives the front end of the aluminum alloy profile 4 to pass through the two first support frames 206, the first hydraulic cylinder 208 located on the first support frame 206 starts to operate, and the telescopic end of the first hydraulic cylinder 208 drives the pressing plate 209 to move downward, and the first guide rods 207 installed at both ends of the pressing plate 209 slide between the first support frame 206. The setting of the first guide rod 207 enhances the firmness. At the same time, the second hydraulic cylinder 211 located on the mounting plate 210 operates at the same time, and the second hydraulic cylinder 211 drives the positioning plate 212 to move forward until the pressing plate 209 and the positioning plate 212 both contact the aluminum alloy. Profile 4, at this time, the aluminum alloy profile 4 is effectively clamped and fixed, which improves the stability of the aluminum alloy profile 4 during the cutting process, and is also beneficial to the transportation of the aluminum alloy profile 4 during the subsequent cutting process. After the clamps on the two first support frames 206 clamp the aluminum alloy profile 4, the first motor 204 located on the outer wall of the cutting machine body 1 starts to drive the first screw rod 205 to rotate. Due to the threaded connection between the connecting plate 203 at the bottom of the slide plate 202 and the first screw rod 205, the slide plate 202 is driven to move along the first guide rail 201 at the bottom toward the saw blade 704 until the front end of the aluminum alloy profile 4 is transported to the position of the saw blade 704, and then the cutting of the aluminum alloy profile 4 is completed at one time. It is easy to operate and has strong flexibility.

[0026] Specifically, Figure 1 , Figure 2 and Figure 5 As shown, the feeding structure 3 includes a connecting frame 301 and a mounting frame 302 fixedly connected to the connecting frame 301, the end of the cutting machine body 1 is fixedly connected to the connecting frame 301, a plurality of conveying rollers 303 are rotatably connected to the mounting frame 302, a second motor 304 is fixedly connected to the side wall of the mounting frame 302, one end of the rotating shaft of one of the conveying rollers 303 is fixedly connected to a first pulley 305, and the other end is fixedly connected to the output shaft of the second motor 304, another first pulley 305 is fixedly connected to the rotating shaft of the other conveying roller 303, and a first belt wheel 305 is wound around the two first belt wheels 305. The connecting frame 301 is provided with a plurality of guide frames 308 fixedly connected to one end of the connecting frame 301 near the mounting frame 302, and a bracket 307 is fixedly connected to the other end of the connecting frame 301, and the bracket 307 is in contact with the aluminum alloy profile 4. The bottom surface of the connecting frame 301 is fixedly connected to a first hydraulic rod 309, and the telescopic end of the first hydraulic rod 309 is fixedly connected to a push plate 310, and the push plate 310 is slidably connected to the bracket 307. In the process of conveying the aluminum alloy profile 4 to the cutting machine body 1, the whole bundle of aluminum alloy profiles 4 is first transported between the brackets 307, so that the multiple aluminum alloy profiles 4 are regularly stacked on the bracket 307. , due to the size limitation of the mounting frame 302 and the conveying roller 303, the number of single-layer aluminum alloy profiles 4 on the bracket 307 is set. At this time, the power of the equipment is turned on, and then the first hydraulic rod 309 located at the bottom of the connecting frame 301 starts to operate. The telescopic end of the first hydraulic rod 309 drives the push plate 310 to move in the direction of the mounting frame 302. At this time, the push plate 310 pushes the aluminum alloy profile 4 at the bottom layer to move in the direction of the mounting frame 302. At the same time, since a plurality of guide frames 308 are fixedly connected to the connecting frame 301 in the direction close to the mounting frame 302, it is avoided that the aluminum alloy profile 4 on the upper layer is displaced or deviated when the aluminum alloy profile 4 at the bottom layer is pushed. The bottom layer of aluminum alloy profile 4 is completely pushed between the multiple conveying rollers 303. At this time, the second motor 304 located on the mounting frame 302 drives one of the conveying rollers 303 to rotate, and the conveying roller 303 drives the first pulley 305 on the rotating shaft to rotate. The first pulley 305 drives another first pulley 305 on the other conveying roller 303 to rotate through the first belt 306. At this time, the two conveying rollers 303 cooperate with each other to drive the aluminum alloy profile 4 to move onto the cutting machine body 1. At this time, the automatic loading of the aluminum alloy profile 4 is completed, avoiding manual alignment of the aluminum alloy profile 4 with the clamp on the cutting machine body 1, thereby improving the operating efficiency.

[0027] When the present invention is in use, before using the equipment, the height of the saw blade 704 is adjusted according to the size of the aluminum alloy profile 4 to be cut. When it is necessary to cut an aluminum alloy profile 4 of a larger size, the height of the saw blade 704 needs to be raised. Only the power of the equipment needs to be turned on. At this time, the telescopic end of the second hydraulic rod 603 extends upward, thereby driving the two drive frames 601 to slide upward along the third guide rod 507. The two drive frames 601 drive the two load-bearing bars 602 and the saw blade 704 arranged thereon to move upward. At this time, the height of the saw blade 704 extending outward on the cutting machine body 1 is effectively increased, which is convenient for cutting aluminum alloy profiles 4 of different sizes. The operation is simple and the flexibility is strong. During the cutting process, the third motor 705 installed at the end of the load-bearing bar 602 drives the third screw rod 706 to rotate. Since the bottom surface of the mounting seat 703 is connected through four slide blocks 7 02 is slidably connected with the second guide rail 701, and the mounting seat 703 is threadedly connected with the third screw rod 706, so that the third screw rod 706 drives the mounting seat 703 to move back and forth along the second guide rail 701, so that the mounting seat 703 drives the saw blade 704 arranged above it to move back and forth, thereby achieving the purpose of completely cutting the aluminum alloy profile 4. At the same time, during the movement of the mounting seat 703, the fourth motor 708 located at the bottom thereof drives the second pulley 709 on the output shaft to rotate, and the second pulley 709 drives the third pulley 710 installed on the reducer 707 to rotate through the second belt 711, so that the third pulley 710 drives the rotating shaft of the reducer 707 and the saw blade 704 at the other end of the rotating shaft to rotate, and cooperates with the mounting seat 703 to move back and forth, thereby completing the cutting of the aluminum alloy profile 4, which is easy to operate and has high cutting efficiency; During the cutting process, if it is found that the saw blade 704 is stuck by the aluminum alloy profile 4 or receives too much resistance and other abnormal phenomena, in order to avoid damage to the saw blade 704 or fragments flying around, it is only necessary to quickly pull the pull rod 510 on the side of the cutting machine body 1, and then the pull rod 510 drives the two blocks 509 inside the docking block 508 to slide outward, and at the same time one of the blocks 509 compresses the spring 511 until the two blocks 509 are no longer engaged with the grooves provided on the support plate 504. At this time, the support plate 504 and the mounting plate 508 are The cutting part installed above it moves downward rapidly under the action of gravity and the tension of the tension spring 505, so that the saw blade 704 moves downward rapidly until it is completely retracted into the interior of the cutting machine body 1. At the same time, since the support plate 504 slides downward along the guide plate 502 and the second guide rod 503 at the same time, the stability of the overall movement process is guaranteed. When the support plate 504 slides downward until the bottom hits the two limit blocks 506, the two tension springs 505 first restore to their initial lengths, and the support plate 504 and the cutting part of the device will continue to move downward under the action of inertia, and at this time the tension spring 505 will be compressed, so that the tension spring 505 plays a buffering role. At the same time, the limit block 506 installed at the bottom of the guide plate 502 is made of rubber material, which can prevent the support plate 504 and the cutting part of the device from continuing to slide downward, and at the same time plays a buffering effect, which is highly practical. At this time, the saw blade 704 is effectively retracted to the internal space of the cutting machine body 1, avoiding the damage caused by the saw blade 704 continuing to cut, thereby improving safety. At the same time, when the pull rod 510 is not pulled, Since the docking block 508 is threadedly connected with the second screw rod 512, the second screw rod 512 can be driven to rotate on the load-bearing beam 501 by turning the knob 513, so that the second screw rod 512 drives the docking block 508 and the support plate 504 to move upward, and at this time the support plate 504 drives the second hydraulic rod 603 and the two drive racks 601 to move upward, and the two drive racks 601 drive the cutting part of the equipment to move upward, so that it is easy to adjust the height of the second hydraulic rod 603 and the entire cutting part, which is easy to operate and has strong flexibility; In the process of conveying the aluminum alloy profiles 4 onto the cutting machine body 1, the whole bundle of aluminum alloy profiles 4 is first moved between the brackets 307, so that multiple aluminum alloy profiles 4 are regularly stacked on the brackets 307. Due to the size restrictions of the mounting frame 302 and the conveying roller 303, the number of single-layer aluminum alloy profiles 4 on the bracket 307 is set. At this time, the power of the equipment is turned on, and then the first hydraulic rod 309 located at the bottom of the connecting frame 301 starts to operate. The telescopic end of the first hydraulic rod 309 drives the push plate 310 to move toward the mounting frame 302. At this time, the push plate 310 pushes the bottom layer of aluminum alloy profiles 4 to move toward the mounting frame 302. At the same time, since the connecting frame 301 is fixedly connected to the direction close to the mounting frame 302 with multiple guide frames 308, it is avoided When the aluminum alloy profile 4 at the bottom layer is pushed, the aluminum alloy profile 4 at the upper layer is displaced or offset, and the aluminum alloy profile 4 at the bottom layer is completely pushed between the multiple conveying rollers 303. At this time, the second motor 304 located on the mounting frame 302 drives one of the conveying rollers 303 to rotate, and the conveying roller 303 drives the first pulley 305 on the rotating shaft to rotate. The first pulley 305 drives another first pulley 305 on another conveying roller 303 to rotate through the first belt 306. At this time, the two conveying rollers 303 cooperate with each other to drive the aluminum alloy profile 4 to move onto the cutting machine body 1. At this time, the automatic loading of the aluminum alloy profile 4 is completed, avoiding manual alignment of the aluminum alloy profile 4 with the fixture on the cutting machine body 1, thereby improving the operating efficiency; When the aluminum alloy profile 4 on the connecting frame 301 is conveyed to the cutting machine body 1, the two first support frames 206 on the slide plate 202 are located at one end of the cutting machine body 1 close to the connecting frame 301. When the conveying roller 303 drives the front end of the aluminum alloy profile 4 to pass through the two first support frames 206, the first hydraulic cylinder 208 located on the first support frame 206 starts to operate, and the telescopic end of the first hydraulic cylinder 208 drives the pressure plate 209 to move downward, and the first guide rods 207 installed at both ends of the pressure plate 209 slide with the first support frame 206. The setting of the first guide rod 207 enhances the firmness, and at the same time, the second hydraulic cylinder 211 located on the mounting plate 210 operates at the same time, and the second hydraulic cylinder 211 drives the positioning plate 212 to move forward until the pressure plate 209 is pressed. The plate 209 and the positioning plate 212 both contact the aluminum alloy profile 4, and the aluminum alloy profile 4 is effectively clamped and fixed at this time, which improves the stability of the aluminum alloy profile 4 during the cutting process, and is also beneficial to the transportation of the aluminum alloy profile 4 during the subsequent cutting process. After the clamps on the two first support frames 206 clamp the aluminum alloy profile 4, the first motor 204 located on the outer wall of the cutting machine body 1 starts to drive the first screw rod 205 to rotate. Due to the threaded connection between the connecting plate 203 at the bottom of the slide plate 202 and the first screw rod 205, the slide plate 202 is driven to move along the first guide rail 201 at the bottom toward the saw blade 704 until the front end of the aluminum alloy profile 4 is transported to the position of the saw blade 704, and then the cutting of the aluminum alloy profile 4 is completed at one time. It is easy to operate and has strong flexibility.
