Description

Technical Field

[0001] The utility model relates to a cutting and processing device. Background Art

[0002] An automobile dust cover is a dust-proof device used for automobiles. Generally, the automobile dust cover is blow-molded by a blow molding machine. After the automobile dust cover is formed, it is also necessary to cut the upper and lower ends of the automobile dust cover. The traditional cutting and processing device drives a cutting knife to translate and cut the end of the automobile dust cover through a piston rod of a cylinder. This cutting method will cause the cutting knife to simultaneously squeeze and cut the end of the automobile dust cover while cutting the end of the automobile dust cover, resulting in the end of the cut automobile dust cover bending and deforming in the cutting direction. Even if the cutting speed and cutting pressure of the cutting knife can be guaranteed, the end of the automobile dust cover will still bend and deform to a certain extent in the cutting direction, ultimately resulting in the end face of the end of the automobile dust cover being inclined, and the flatness of the end of the cut automobile dust cover cannot be guaranteed.

[0013] The beneficial effects of the present utility model are:

[0014] Compared with the prior art, the cutting and processing device adopting the structure of the present utility model can use the swinging member to enable the cutting tool to automatically approach the through hole. When the part of the end of the automotive dust cover that needs to be cut penetrates into the through hole, as the cutting tool automatically approaches the through hole, the cutting edge of the cutting tool will eventually press against the outer wall of the end of the automotive dust cover. Under the action of centrifugal force, the swinging member will gradually drive the cutting tool closer to the center of the through hole, so that the cutting tool gradually cuts into the end of the automotive dust cover. At the same time, the cutting tool rotates with the centrifugal seat. Therefore, the cutting tool will not stay at the same cutting point for a long time, thus avoiding the situation that the end of the automotive dust cover is bent and deformed due to a single cutting direction. When the cutting tool cuts around the end of the automotive dust cover with the centrifugal seat, the pressure of the cutting tool can be evenly applied to the end of the automotive dust cover. After the cutting tool makes a shallow circumferential cut on the outer wall of the end of the automotive dust cover, under the action of the swinging member, it will further cut deeper circumferentially into the end of the automotive dust cover, and finally cut off the part of the end of the automotive dust cover that needs to be cut. This cutting method can avoid to the greatest extent the situation that the cutting surface of the automotive dust cover is inclined after being cut due to the influence of unidirectional cutting pressure, and effectively ensure the flatness of the end of the automotive dust cover after cutting and processing.

[0025] A number of seventh screwing holes evenly distributed in a circle are provided on the upper surface of the centrifugal seat 514.

[0026] One end of the cutting knife 523 adjacent to the through hole 521 is provided with an arc-shaped left cutting edge 557 on the left outer edge; one end of the cutting knife 523 adjacent to the through hole 521 is provided with a linear right cutting edge 558 on the right outer edge; the left cutting edge 557 and the right cutting edge 558 enclose a cutting angle 559; the angle of the cutting angle 559 is less than 60 degrees.

[0027] The upper surface of the end of the swinging member 517 is provided with a guiding groove 560 matching the tail of the cutting knife 523; the upper surface of the cutting knife 523 is higher than the upper notch of the guiding groove 560; a long circular hole is provided at the tail of the cutting knife 523, and the fastening screw 529 passes through the long circular hole.

[0028] The upper fixing frame 501 is arranged on the inner wall of the left side of the frame.

[0029] The usage method of the present utility model is as follows:

[0030] When it is necessary to cut the upper and lower ends of the automotive dust cover, the grasping device can be used to transfer the automotive dust cover to between the upper and lower clamping holes 511, and then the end of the automotive dust cover can enter the through hole 521 through the clamping hole 511. At this time, a part of the end of the automotive dust cover that enters the through hole needs to be cut and trimmed. After cutting and trimming, the flatness of the end of the automotive dust cover can be ensured. When it is necessary to cut and trim the part of the automotive dust cover that enters the through hole 521, the driving motor 535 can be started. At this time, the motor shaft of the driving motor 535 will drive the lower transmission shaft 538 to rotate. The lower transmission shaft 538 and the upper transmission shaft 541 are connected by the middle transmission shaft 547. Therefore, when the lower transmission shaft 538 rotates, the upper transmission shaft 541 rotates synchronously, so as to realize the synchronous rotation of the upper driving wheel 544 and the lower driving wheel 539. The upper driving wheel 544 and the upper driven wheel 516, and the lower driving wheel 539 and the lower driven wheel 516 are all connected by the synchronous belt 545. When the upper driving wheel 544 and the lower driving wheel 539 rotate, the upper and lower driven wheels 516 rotate accordingly, so as to realize the rotation of the centrifugal seat 514.

[0031] When the centrifuge base 514 rotates, a centrifugal force is generated on the centrifuge base 514, which directly affects the swinging member 517. The weight of the end of the swinging member 517 without the cutting blade 523 is greater than the weight of the end of the swinging member 517 with the cutting blade 523. Under the action of the centrifugal force, the end of the swinging member 517 without the cutting blade 523 will be thrown outwards, while the end of the swinging member 517 with the cutting blade 523 will approach the through hole 521. At the same time, the cutting edge of the cutting blade 523 faces the through hole 521. As the cutting blade 523 approaches the through hole 521, the cutting blade 523 will ultimately directly cut on the part of the automotive dust cover that enters the through hole 521. As the centrifuge base 514 rotates one circle, the cutting blade 523 also completes one circle of cutting work. By continuously cutting in circles like this, the excess part at the end of the automotive dust cover can be stably cut off, ensuring the cutting quality. After the end of the automotive dust cover is cut and trimmed, finally, the grasping device will move the automotive dust cover directly above the position where the finished product box is placed. As the grasping device releases the automotive dust cover, the automotive dust cover will directly fall into the finished product box, completing the collection of the finished product.

[0032] Since the clamping plate 526 is fixed to the swinging member 517 by the fastening screw 529, it is only necessary to loosen the fastening screw 529 to adjust the position of the cutting blade 523 clamped between the clamping plate 526 and the swinging member 517 according to actual needs. When the swinging member 517 swings under the influence of the centrifugal force, the positioning screw 530 moves accordingly. At this time, the positioning screw 530 presses one end of the torsion spring 534, causing the torsion spring 534 to generate elasticity. As the rotation of the centrifuge base 514 ends, without the clamping action of the centrifugal force, the elasticity of the torsion spring 534 will cause the positioning screw 530 to reset, thereby realizing the reset of the swinging member 517. At this time, the end of the swinging member 517 with the cutting blade moves away from the through hole 521, effectively avoiding the situation where the port of the next automotive dust cover to be cut is blocked by the cutting blade 523 and cannot pass through the through hole 521.

[0033] A plurality of uniformly distributed second oblong holes 550 are provided on the upper adjusting plate 502. A plurality of fifth screw holes corresponding to the positions of the second oblong holes 550 are provided on the upper surface of the upper fixing plate 503. A plurality of uniformly distributed third oblong holes 552 are provided on the lower adjusting plate 507. The third oblong holes 552 are perpendicular to the second oblong holes 550. A plurality of sixth screw holes corresponding to the positions of the third oblong holes 552 are provided on the lower surface of the lower fixing plate 508. The second oblong holes 550 and the fifth screw holes, as well as the third oblong holes 552 and the sixth screw holes, can be fixed by screws. Just by pressing the heads of the screws against the upper surface of the upper adjusting plate 502 and the lower surface of the lower adjusting plate 507, the position fixing of the upper adjusting plate 502 and the lower adjusting plate 507 can be completed. When the second oblong holes 550 and the third oblong holes 552 are perpendicular to each other, when the second oblong holes 550 can adjust the left and right positions of the upper adjusting plate 502, the third oblong holes 552 can adjust the front and back positions of the lower adjusting plate 507, thereby effectively changing the positions of the through holes 521 on the upper and lower sides, achieving the effect of finely adjusting the positions of the through holes 521 on the upper and lower sides, and further ensuring the cutting quality of the upper and lower ends of the automotive dust cover.

[0034] The lower end of the upper transmission shaft 541 is connected to the upper end of the middle transmission shaft 547 through an upper universal joint 548 located in the upper universal hole 546. The upper end of the lower transmission shaft 538 is connected to the lower end of the middle transmission shaft 547 through a lower universal joint 549 located in the lower universal hole 540. The upper universal joint 548 and the lower universal joint 549 can achieve the effect of universal rotation. Therefore, even if the through holes 521 on the upper and lower sides are not coaxial, the stable rotation of the upper transmission shaft 541 and the lower transmission shaft 538 can still be ensured, thereby ensuring the stable rotation of the upper and lower centrifugal seats 514. The middle transmission shaft 547 can adopt a telescopic structure with an inner tube and an outer tube, which can achieve the effect of automatically adjusting the length of the middle transmission shaft 547 to accommodate the change in the position of the through hole.

[0035] A plurality of seventh screw holes evenly distributed in a circle are provided on the upper surface of the centrifugal seat 514. A plurality of weight blocks 555 corresponding to the positions of the seventh screw holes are placed on the upper surface of the centrifugal seat 514. A counterbore 556 communicating with the seventh screw hole is provided on the weight block 555. The first screw hole and the counterbore 556 can be connected and fixed by screws. This fixing method facilitates the disassembly and assembly of the weight block 555. The presence of the weight block 555 can effectively adjust the center of gravity of the centrifugal seat 514, avoiding the situation where the centrifugal seat 514 has only the swing member 517 and causing deviation of the centrifugal seat 514, and avoiding the situation where the center of the centrifugal seat 514 is offset and the rotation is unstable, thereby affecting the cutting quality.

[0036] One end of the cutting knife 523 adjacent to the through hole 521 is provided with an arc-shaped left cutting edge 557 on the outer edge of the left side, and one end of the cutting knife 523 adjacent to the through hole 521 is provided with a linear right cutting edge 558 on the outer edge of the right side. The existence of the left cutting edge 557 and the right cutting edge 558 enables the cutting knife to have cutting ability on both the left and right sides. Even if it is not the tip of the cutting knife 523 that contacts the automotive dust cover, but the edges on both sides of the cutting knife 523 that contact the automotive dust cover, the redundant part on the automotive dust cover can be cut off, further ensuring the progress of the cutting work. The left cutting edge 557 and the right cutting edge 558 enclose a cutting angle 559, and the angle of the cutting angle 559 is less than 60 degrees, which can effectively improve the sharpness of the cutting knife 523, thereby further improving the cutting ability of the cutting knife 523.

[0037] The upper surface of the end of the swing member 517 is provided with a guiding groove 560 that matches the tail of the cutting knife 523. The tail of the cutting knife 523 is provided with an oblong hole, and the fastening screw 529 passes through the oblong hole. The existence of the guiding groove 560 and the oblong hole can both ensure the guiding effect when moving the cutting knife 523, avoiding the situation that the cutting knife 523 deviates in angle during movement and affecting the normal cutting of the cutting knife 523. The upper surface of the cutting knife 523 is higher than the upper notch of the guiding groove 560, which is convenient for the clamping plate 526 to effectively fix the cutting knife 523 with the fastening force of the fastening screw 529 after the cutting knife 523 is displaced.

[0038] The upper fixing frame 501 is arranged on the inner wall of the left side of the frame. The upper fixing frame 501 and the lower fixing frame 506 are both fixed on the inner wall of the left side of the frame, which can form a fixed reference, thereby ensuring that each component can stably perform its own function.
