[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. In the starting motor of the present invention, the motor drives the circular ring frame and the anti-slip pad to twist. The anti-slip pad improves the stability of driving the metal ring to rotate. At this time, the twisting operation of the metal ring can be realized. The staff only needs to aim the laser head at a point on the metal ring to realize the cutting operation of the metal ring, avoiding the phenomenon that the metal ring needs to be clamped multiple times to realize cutting. By setting the annular groove on the side wall of the anti-slip pad, it is possible to avoid the generation of burrs and other protrusions during the cutting of the metal ring. These protrusions are pressed on the anti-slip pad, affecting the subsequent stable driving rotation of the metal ring.

At this time, the V-shaped groove of the clamping plate can be used to realize the stable clamping and processing work of the metal pipe or metal ring, improving the flexibility of using the laser cutting fixture. By setting the clamping structure, it is convenient for the flexible clamping and cutting work of the metal ring structure product, and the rotation work during the cutting of the metal ring can be realized, thereby improving the cutting efficiency of the metal ring structure.

[0032] 2. In the present invention, the second driving rod drives the baffle to move towards the surface close to the end side of the metal ring until the baffle moves to a position where it abuts against the side of the metal ring. At this time, the limiting work on both end sides of the metal ring can be realized, avoiding the phenomenon of displacement of the metal ring during the rotation process, and further improving the stability of cutting the metal ring. During the cutting of the metal ring, the first sandpaper always abuts against the outer surface of the metal ring. During the relative movement between the metal ring and the first sandpaper, the effective polishing and grinding work of the outer surface of the metal ring can be realized, facilitating the polishing work during the cutting of the metal ring product. By setting the limiting structure, it is not only convenient for the stable limiting work on both end sides of the metal ring structure, but also the polishing and grinding work on the outer surface and both end sides can be realized during the rotation process of the metal ring structure, further improving the quality of the metal ring structure after cutting and forming.

[0033] 3. In the present invention, the first grinding head is inserted into the cutting gap on the outer side of the metal ring under the action of the gravity of the gravity ball, and the second grinding head is inserted into the cutting gap on the inner side of the metal ring for filling under the action of the elastic force of the third spring between the rectangular frame and the rectangular block, thereby realizing the filling work of the cutting gap of the metal ring, avoiding the phenomenon of shaking of the metal ring during the rotation process, and both the first grinding head and the second grinding head can realize the chamfering work on the cutting strip slot position, further improving the effect of post-treatment of laser cutting of the metal ring. By setting the auxiliary structure, it is convenient for the real-time filling work of the gap generated during the cutting of the metal ring product, and the chamfering work on the cut seam position can be realized after cutting the metal ring product, further improving the quality of the metal ring product after cutting.

[0046] Please refer to Figure 1-10 , the present invention provides a technical solution: a laser cutting fixture for high-end equipment manufacturing that is convenient for clamping, including a base 1 and a metal ring 5. Two mounting brackets 2 are fixedly installed on the upper surface of the base 1. Two clamping plates 3 are slidably connected to the surface of the mounting brackets 2. A V-shaped notch is provided on the upper side of the clamping plate 3. A bidirectional screw rod 4 is rotatably connected inside the mounting bracket 2. Threads with opposite directions are provided on both sides of the bidirectional screw rod 4. The bidirectional screw rod 4 is threadedly connected to the inside of the clamping plate 3. It further includes: a clamping structure 6 provided on the surface of the clamping plate 3, which is used to assist in clamping the metal ring 5 with a circular ring structure, and the clamped metal ring 5 can rotate, thus facilitating the circumferential cutting work of the metal ring 5; a limiting structure 7 provided inside the clamping plate 3, which can not only limit the two end sides of the metal ring 5, but also polish the two end sides and the cutting surface position of the metal ring 5 after laser cutting; an auxiliary structure 8 provided inside the clamping plate 3, which is used for inserting and supporting the cutting gap position and can also chamfer and polish the cutting gap position. By setting the clamping structure 6, it is convenient for the flexible clamping and circumferential cutting work of the metal ring 5 structure product, and the rotation work during the circumferential cutting of the metal ring 5 can be realized, thereby improving the circumferential cutting efficiency of the metal ring 5 structure. By setting the limiting structure 7, it is not only convenient for the stable limiting work of the two end sides of the metal ring 5 structure, but also the polishing work of the outer surface and the two end sides during the rotation of the metal ring 5 structure can be realized, further improving the quality of the metal ring 5 structure after cutting and forming. By setting the auxiliary structure 8, it is convenient for the real-time filling work of the gap generated during the circumferential cutting of the metal ring 5 product, and the chamfering work of the cut seam position after the circumferential cutting of the metal ring 5 product can be realized, further improving the quality of the metal ring 5 product after circumferential cutting.

[0047] Next, specifically describe the specific settings and functions of its clamping structure 6, limiting structure 7 and auxiliary structure 8.

[0048] As Figures 1-4 and Figure 10As shown, the clamping structure 6 includes a positioning plate 603 fixedly connected to the side wall of the clamping plate 3. A push plate 604 is slidably connected to the side wall of the positioning plate 603. The push plate 604 is of a U-shaped structure. The push plate 604 slidably penetrates through the clamping plate 3. Roller 605 is rotatably connected to both ends of the push plate 604. A rectangular plate 611 is fixedly connected to the side wall of the clamping plate 3. A limiting frame 612 is slidably connected inside the rectangular plate 611. A first spring 613 is fixedly connected between the limiting frame 612 and the rectangular plate 611. When it is necessary to perform a circumcision operation on the metal ring 5, first pull out the limiting frame 612 inside the rectangular plate 611, slide the push plate 604 to the side close to the surface of the clamping plate 3, and release the limiting frame 612. At this time, the limiting frame 612 will lock the push plate 604 under the elastic force of the first spring 613, and the use of the push plate 604 after it extends from the inner side of the clamping plate 3 can be realized. A limiting plate 601 is fixedly connected to the surface of the base 1. An installation plate 602 is slidably connected to the side wall of the limiting plate 601. A motor 607 is fixedly installed inside the installation plate 602. A rotating shaft 608 is fixedly connected to the output end of the motor 607. A circular ring frame 609 is fixedly connected to the side wall of the rotating shaft 608. An anti-slip pad 610 is adhesively connected to the outside of the circular ring frame 609. A first driving rod 606 is threadedly connected inside the installation plate 602. The first driving rod 606 is rotatably connected to the inside of the base 1. Start the motor 607, and the motor 607 will drive the circular ring frame 609 and the anti-slip pad 610 to twist. The setting of the anti-slip pad 610 improves the stability of driving the rotation of the metal ring 5. At this time, the twisting operation of the metal ring 5 can be realized. The anti-slip pad 610 is of a circular ring structure, and an annular groove with a cross-section of an isosceles trapezoid structure is formed on the arc surface of the anti-slip pad 610. By providing the annular groove on the side wall of the anti-slip pad 610, it is possible to avoid the phenomenon that burrs and other protrusions are easily generated during the process of cutting the metal ring 5, and these protrusions are pressed on the anti-slip pad 610, affecting the subsequent stable rotation drive of the metal ring 5.

[0049] As Figures 1-2 and Figure 5 as well as Figure 6As shown, the limit structure 7 includes a sliding frame 71 slidably connected inside the clamping plate 3. A support plate 74 is fixedly connected to the side wall of the sliding frame 71. Two baffle plates 75 are slidably connected to the side wall of the support plate 74. A second driving rod 76 is threadedly connected inside the support plate 74. The second driving rod 76 is rotatably connected to the inside of the baffle plate 75. A second spring 79 is fixedly connected between the sliding frame 71 and the clamping plate 3. By rotating the two second driving rods 76 inside the support plate 74, the second driving rods 76 will drive the baffle plates 75 to move towards the surface on the side close to the metal ring 5 until the baffle plates 75 move to a position where they are in contact with the sides of the metal ring 5. At this time, the limiting work on both ends of the metal ring 5 can be realized. A first abrasive paper 77 is adhesively bonded to the surface of the support plate 74, and a second abrasive paper 78 is adhesively bonded to the surface of the baffle plate 75. The first abrasive paper 77 is located inside the baffle plate 75. During the relative movement between the metal ring 5 and the first abrasive paper 77, an effective polishing and grinding work on the outer surface of the metal ring 5 can be realized, which facilitates the polishing work during the circumferential cutting of the metal ring 5 product, further improving the clamping and driving effect on the metal ring 5 product. And the second abrasive paper 78 is in contact with the end sides of the metal ring 5 to realize the real-time grinding work on both ends of the structure of the metal ring 5, further improving the processing efficiency of the metal ring 5. A jack 73 is opened on one side of the sliding frame 71 close to the support plate 74. A plug 72 is slidably connected inside the clamping plate 3. The size of the plug 72 is adapted to the size of the jack 73. Inserting the plug 72 into the inside of the jack 73 can realize the locking and installation work on the position of the moved sliding frame 71, thus improving the flexibility of using the sliding frame 71.

[0050] As Figures 1-2 and Figures 7-9As shown, the auxiliary structure 8 includes a limit pin 802 fixedly connected to the side wall of the splint 3, the side wall of the limit pin 802 is slidably connected with a rectangular block 807, the internal thread of the rectangular block 807 is connected with the third driving rod 801, the third driving rod 801 and the internal rotation connection of the splint 3, the internal sliding connection of the rectangular block 807 is connected with a rectangular frame 808, the side wall of the rectangular frame 808 is fixedly connected with a grinding rod 810, the side wall of the grinding rod 810 is fixedly connected with a second grinding head 806, and a third spring 809 is fixedly connected between the rectangular block 807 and the rectangular frame 808. While pulling the rectangular frame 808, the third driving rod 801 is rotated to move the grinding rod 810 and the second grinding head 806 to the position inside the metal ring 5. After the second grinding head 806 is moved to the position at the same horizontal plane as the first grinding head 803, the rectangular frame 808 is released. At this time, the rectangular frame 808 is driven by the elastic force of the third spring 809 to drive the third grinding head on the grinding rod 810 to be close to the inside of the metal ring 5. A diamond hole 805 is provided on the surface of the clamping plate 3, and the first grinding head 803 is slidably connected to the inside of the diamond hole 805, and the flat end of the first grinding head 803 is fixedly connected to the gravity ball 804. The first grinding head 803 is inserted into the gap cut on the outside of the metal ring 5 by the gravity of the gravity ball 804. The cross sections of the first grinding head 803 and the second grinding head 806 are both diamond-shaped, and the end sides of the first grinding head 803 and the second grinding head 806 are both provided with a tip. The first grinding head 803 and the second grinding head 806 can both perform grinding and chamfering of the cutting slit positions, further improving the effect of post-processing of the metal ring 5 by laser cutting.

[0051] Working principle: When it is necessary to perform a circumferential cutting operation on the metal ring 5, first pull the limiting frame 612 inside the rectangular plate 611, slide the push plate 604 to the side close to the surface of the clamping plate 3, and release the limiting frame 612. At this time, the limiting frame 612 will be locked by the elastic force of the first spring 613 to lock the push plate 604, and the use operation after the push plate 604 extends from the inner side of the clamping plate 3 can be realized. After placing the metal ring 5 between the two push plates 604, rotate the bidirectional lead screw 4. At this time, the bidirectional lead screw 4 will drive the two clamping plates 3 to move towards each other on the surface of the mounting frame 2 until the four rollers 605 move to the position where the metal ring 5 is limited, and the clamping operation of the metal ring 5 can be realized. At this time, rotate the first driving rod 606, and the first driving rod 606 will drive the mounting plate 602 to slide on the surface of the limiting plate 601 until the anti-slip pad 610 moves to the position close to the lower surface of the metal ring 5. Then start the motor 607, and the motor 607 will drive the circular ring frame 609 and the anti-slip pad 610 to twist. The setting of the anti-slip pad 610 improves the stability of driving the metal ring 5 to rotate. At this time, the twisting operation of the metal ring 5 can be realized. The staff only needs to align the laser head with a point on the metal ring 5 to realize the circumferential cutting operation of the metal ring 5, avoiding the phenomenon that the circumferential cutting can only be realized after multiple clamping of the metal ring 5. By setting the annular groove on the side wall of the anti-slip pad 610, it is possible to avoid the generation of burrs and other protrusions during the process of cutting the metal ring 5. These protrusions are pressed on the anti-slip pad 610, affecting the subsequent stable rotation of the metal ring 5. When it is necessary to stably clamp and cut the metal ring 5 or the metal pipe, the limiting frame 612 can be pulled again to slide the push plate 604 out of the inner side of the clamping plate 3. At this time, the V-shaped groove of the clamping plate 3 can be used to realize the stable clamping and processing operation of the metal pipe or the metal ring 5, improving the flexibility of using the laser cutting fixture. By setting the clamping structure 6, it is convenient to flexibly clamp and circumferentially cut the metal ring 5 structure product, and the rotation operation during the circumferential cutting of the metal ring 5 can be realized, thereby improving the circumferential cutting efficiency of the metal ring 5 structure.

[0052] After clamping the metal ring 5, the pin 72 inside the jack 73 is withdrawn. At this time, the support plate 74 will be pressed against the surface of the metal ring 5 under the elastic force of the spring between the clamping plate 3 and the sliding frame 71. Then, rotate the two second driving rods 76 inside the support plate 74. The second driving rods 76 will drive the baffle 75 to move towards the surface of the metal ring 5 near the end side until the baffle 75 moves to a position where it abuts against the side of the metal ring 5. At this time, the limiting work on both end sides of the metal ring 5 can be realized, avoiding the phenomenon of displacement of the metal ring 5 during the rotation process, and further improving the stability of the circumferential cutting of the metal ring 5. During the circumferential cutting of the metal ring 5, the first sandpaper 77 will always be pressed against the outer surface of the metal ring 5. During the relative movement between the metal ring 5 and the first sandpaper 77, the effective polishing and grinding work on the outer surface of the metal ring 5 can be realized, facilitating the polishing work during the circumferential cutting of the metal ring 5 product, and further improving the effect of clamping and driving the metal ring 5 product. The second sandpaper 78 is pressed against the end side position of the metal ring 5 to realize the real-time grinding work on both end sides of the metal ring 5 structure, further improving the processing efficiency of the metal ring 5. When it is not necessary to grind the metal ring 5, the sliding frame 71 can be pulled. When the jack 73 on the sliding frame 71 moves to the position corresponding to the pin 72, insert the pin 72 into the inside of the jack 73, and the locking installation work of the position of the sliding frame 71 after movement can be realized, thus improving the flexibility of using the sliding frame 71. By setting the limiting structure 7, it is not only convenient for the stable limiting work on both end sides of the metal ring 5 structure, but also the polishing and grinding work on the outer surface and both end sides of the metal ring 5 structure during the rotation process can be realized, further improving the quality of the metal ring 5 structure after cutting and forming.

[0053] After the metal ring 5 is clamped, the first grinding head 803 can be inserted into the inner side of the diamond hole 805. The first grinding head 803 will be pressed against the outer side of the metal ring 5 by the gravity of the gravity ball 804. The third driving rod 801 is rotated while the rectangular frame 808 is pulled to move the grinding rod 810 and the second grinding head 806 to the inner side of the metal ring 5. After the second grinding head 806 is moved to the position on the same horizontal plane as the first grinding head 803, the rectangular frame 808 is released. The third grinding head on the grinding rod 810 will be driven by the elastic force of the third spring 809 to be close to the inner side of the metal ring 5. In the process of real-time cutting of the metal ring 5, when the metal ring 5 is completely cut, the first grinding head 803 will be inserted into the gap cut on the outer side of the metal ring 5 by the gravity of the gravity ball 804, and the second grinding head 806 will be inserted into the gap cut on the inner side of the metal ring 5 by the elastic force of the third spring 809 between the rectangular frame 808 and the rectangular block 807 to fill it, thereby achieving the metal ring 5 being cut in real time. 5 The filling work of the cutting gap of the metal ring 5 can avoid the shaking of the metal ring 5 during the driving and rotating process, and the first grinding head 803 and the second grinding head 806 can both grind and chamfer the cutting slit position, further improving the effect of post-processing of the metal ring 5 by laser cutting, and improving the quality of laser cutting of the product. When the tip of the second grinding head 806 is completely inserted into the inner side of the gap, the grinding rod 810 can polish and grind the inner side of the metal ring 5, which is convenient for the comprehensive grinding work of the metal ring 5 product. After the grinding is completed, the driving rod can be rotated to retract the second grinding head 806 and the grinding rod 810, and the first grinding head 803 can be directly withdrawn from the inner side of the diamond hole 805, which improves the flexibility of processing the metal ring 5 product. By setting the auxiliary structure 8, the real-time filling work of the gap generated during the ring cutting process of the metal ring 5 product is facilitated, and the chamfering work of the cutting slit position after the ring cutting of the metal ring 5 product can be realized, which further improves the quality of the metal ring 5 product after the ring cutting.
