[0014] Technical effects and advantages of the present invention:

[0015] 1. The present invention pushes the pipe to the center of the circle when the positioning rings are merged, and then controls the connecting plates on both sides to move inward to merge the positioning rings. At this time, the pipe is located in the positioning ring, and then the pipe is clamped by the clamping blocks on all sides at the same time, so that the loading and positioning of the pipe is completed. When loading pipes with a certain length, the equipment space requirement is reduced, and it is more convenient to load, and pipes of different diameters can be clamped and positioned. A first ball is provided in the clamping surface of the clamping block, so that the first ball contacts the surface of the pipe, which facilitates the subsequent movement of the pipe in the clamping state. Subsequently, the first driving wheel and the second driving wheel are respectively pressed and contacted with the surface of the pipe, and the pipe is controlled to slide and rotate in the clamping block, so that the cutting part of the pipe passes over the laser cutting gun to complete the cutting of the pipe.

[0016] 2. The present invention provides a conical inclined surface in the material preparation rack, so that the pipes to be processed stored on both sides will roll toward the center position, and one of the pipes to be processed will fall on the lifting block. Then, by controlling the operation of the third cylinder, the lifting block can be driven to move upward, and then the pipe to be processed can be moved upward. When the pipe moves to the center of the circle when the positioning rings are combined, the positioning rings can be combined and then the pipe can be clamped by the clamping block. Then, by controlling the lifting block to descend and reset, a pipe to be processed will be replenished on the lifting block, which is convenient for continuous lifting and loading.

[0017] 3. After the cutting position of the pipe in the present invention passes the laser cutting gun, the adjusting block moves to the center point of the cutting part, and then the pipe can be clamped by the clamping plate. When the pipe is subsequently cut, the pipe at the cut position can be prevented from falling, thereby improving the stability of the pipe when it is cut. Moreover, due to the contact between the second ball and the pipe, the overall rotation of the pipe when it is cut will not be affected. After the pipe is cut, the cut pipe is moved to the top of the conveyor belt, and then the clamping plate is opened so that the cut pipe can fall down onto the conveyor belt, and finally the pipe is transported by the conveyor belt.

In addition, the forms of the various structures recorded in the following embodiments are only examples. The laser cutting device for pipes used in the manufacture of hardware products involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0030] like Figure 1-Figure 8 As shown, in one embodiment, a tube laser cutting device for hardware product manufacturing is proposed, including a machine base 1 and a laser cutting gun 2 arranged on the machine base 1, a feeding mechanism 3 is arranged at the lower end of the machine base 1, a positioning assembly 4 and a material receiving mechanism 5 are arranged at the upper end of the machine base 1, the material receiving mechanism 5 is used to transfer the cut tube, the positioning assembly 4 includes an opening mechanism 41 and a clamping mechanism 42, the opening mechanism 41 includes a support seat 411, a connecting plate 412, a first cylinder 414 and a positioning ring 413, a pair of support seats 411 are fixedly arranged at the upper end of the machine base 1, the connecting plates 412 are slidably connected to the support seats 411 through guide rods, a plurality of positioning rings 413 are fixedly arranged on the inner side of the connecting plate 412, the connecting plate 412 is connected to the output end of the first cylinder 414 fixedly connected to the surface of the support seat 411, and a feed port 415 is opened on the upper end surface of the machine base 1;

[0031] The clamping mechanism 42 includes a connecting rod 421, a clamping block 422, a first ball 425 and a second cylinder 423. The multiple connecting rods 421 are slidably connected to the connecting plate 412 through a guide rod, and the multiple clamping blocks 422 are fixedly connected to the surface of the connecting rod 421. The clamping block 422 is slidably connected to the positioning ring 413. The connecting rod 421 is connected to the output end of the second cylinder 423 fixedly connected to the surface of the connecting plate 412. The clamping surface of the clamping block 422 is provided with multiple first ball grooves 424, and multiple first balls 425 are arranged in the first ball grooves 424.

[0032] In actual application of the embodiment of the present invention, the feeding mechanism 3 can push the pipe upward through the feed port 415, so that the pipe is pushed to the center of the circle when the positioning rings 413 are merged, and then the first cylinder 414 is controlled to drive the connecting plates 412 on both sides to move inward, so that the positioning rings 413 are merged, and the pipe is located in the positioning ring 413. Subsequently, the second cylinder 423 is controlled to operate so that multiple connecting rods 421 move toward the pipe at the same time, driving the clamping blocks 422 around to clamp the pipe at the same time, and the feeding positioning of the pipe is completed. When loading pipes of a certain length, the space requirement for equipment is reduced, and loading is more convenient. Moreover, pipes of different diameters can be clamped and positioned. A first ball 425 is provided in the clamping surface of the clamping block 422 so that the first ball 425 contacts the surface of the pipe, facilitating the subsequent movement of the pipe in the clamping state. Subsequently, the pipe is controlled to move forward so that the cutting portion passes over the laser cutting gun 2, and the portion passing over the laser cutting gun 2 is clamped by the material receiving mechanism 5. When the laser cutting gun 2 cuts the pipe, the material receiving mechanism 5 can be used to complete the unloading and transportation of the cut pipe.

[0033] like Figure 7 and 8 As shown, as a preferred embodiment of the present invention, the loading mechanism 3 includes a material preparation rack 301, a mounting rack 303 and a lifting block 304. The material preparation rack 301 is fixedly arranged at the lower end of the machine base 1, and a conical inclined surface 302 is arranged on the inner surface of the material preparation rack 301. The mounting rack 303 is fixedly arranged at the lower end of the material preparation rack 301. The lifting block 304 is slidably connected to the material preparation rack 301 through a guide rod, and the lifting block 304 is connected to the output end of the third cylinder 305 fixedly connected to the lower end of the material preparation rack 301.

[0034] When the embodiment of the present invention is actually applied, by placing the pipes to be processed in the preparation rack 301, the conical slope 302 is provided in the preparation rack 301, and the pipes stored on both sides will roll toward the center position, and one of the pipes will fall on the lifting block 304. Then, by controlling the operation of the third cylinder 305, the lifting block 304 can be driven to move upward, and then the pipe can be moved upward. When the pipe moves to the center of the circle when the positioning rings 413 are merged, the positioning rings 413 can be merged and then the pipe can be clamped by the clamping block 422. Then, by controlling the lifting block 304 to descend and reset, a pipe to be processed will be replenished on the lifting block 304 for subsequent lifting and loading.

[0035] like Figure 5 and 6As shown, as another preferred embodiment of the present invention, a material moving mechanism 6 is arranged in the clamping block 422, and the material moving mechanism 6 includes a slide groove 601, a first slider 602, a second slider 603, a gear 608, a driving motor 606 and a bidirectional motor 604. The slide groove 601 is opened in the clamping block 422, and the first slider 602 and the second slider 603 are both slidably connected in the slide groove 601. The lower end of the first slider 602 is fixedly connected to the bidirectional motor 604, and the output end of the bidirectional motor 604 is rotatably connected to the first driving wheel 605 through a rotating shaft. The lower end of the second slider 603 is fixedly connected to the driving motor 606, and the output end of the driving motor 606 is rotatably connected to the second driving wheel 607 through a driving shaft. The gear 608 is rotatably connected in the clamping block 422, and the inner surfaces of the first slider 602 and the second slider 603 are both provided with tooth grooves 609 meshing with the gear 608.

[0036] In actual application of the embodiment of the present invention, after the pipe to be processed is clamped in the clamping block 422, the first slider 602 is controlled to slide, so that the multiple first drive wheels 605 squeeze the surface of the pipe, and then the bidirectional motor 604 is operated to drive the first drive wheel 605 to rotate, and at the same time, with the first ball 425 at the bottom, the pipe can be driven to move forward, so that the part to be cut passes the laser cutting gun 2, and then the first slider 602 is controlled to slide in the opposite direction, so that the first drive wheel 605 is away from the pipe body. At this time, under the action of the gear 608 and the tooth groove 609, the first slider 602 will move relative to the second slider 603, and the second slider 603 slides in the opposite direction. At this time, the first slider 602 will drive the multiple second drive wheels 607 to squeeze the surface of the pipe, and then by controlling the drive motor 606 to operate, the pipe body can be driven to rotate. At this time, with the action of the laser welding gun, the pipe body can be circularly cut.

[0037] In one case of an embodiment of the present invention, the outer surfaces of the first driving wheel 605 and the second driving wheel 607 are both made of rubber material, so when the multiple first driving wheels 605 and the multiple second driving wheels 607 squeeze the pipe, the friction between them and the pipe is relatively large. Then, the pipe is in contact with the multiple first balls 425 all around. When the first driving wheel 605 and the multiple second driving wheels 607 rotate respectively, the effect of controlling the pipe to slide and rotate can be achieved.

[0038] like Figure 6 As shown, as another preferred embodiment of the present invention, an electric push rod 6010 is fixedly connected inside the clamping block 422 , and an output end of the electric push rod 6010 is fixedly connected to the first slider 602 .

[0039] In actual application, the embodiment of the present invention controls the operation of the electric push rod 6010. When the electric push rod 6010 is extended to the extreme position, the first drive wheel 605 can be squeezed and fitted with the surface of the pipe. When the electric push rod 6010 is reset to the extreme position, the second drive wheel 607 can be squeezed and fitted with the pipe, thereby achieving the timing of controlling the contact between the first drive wheel 605 and the second drive wheel 607 and the pipe.

[0040] like Fig. 9 and 10 As shown, as another preferred embodiment of the present invention, a support frame 201 is fixedly connected to the upper end of the machine base 1, a fourth cylinder 202 is fixedly connected to the upper end of the support frame 201, an output end of the fourth cylinder 202 is slidingly connected to the support frame 201, and a laser cutting gun 2 is fixedly connected to the output end of the fourth cylinder 202.

[0041] In actual application of the embodiment of the present invention, when the pipe cutting position passes the laser cutting gun 2, the fourth cylinder 202 is controlled to operate according to the diameter of the pipe, so that the laser cutting gun 2 can be controlled to approach the surface of the pipe. Subsequently, the cutting operation of the laser cutting gun 2 can be completed by rotating the pipe and starting the laser cutting gun 2.

[0042] like Fig. 9 and 10 As shown, as another preferred embodiment of the present invention, the material receiving mechanism 5 includes a rotating seat 501, a threaded rod 502, a driving block 505, an adjusting block 506 and a clamping plate 507. The rotating seat 501 is fixedly arranged at the upper end of the machine base 1, and the threaded rod 502 is rotatably connected to the rotating seat 501 and the support frame 201. One of the threaded rods 502 is connected to the output end of the displacement motor 503 fixedly arranged on the surface of the rotating seat 501, and the threaded rods 502 are connected by a sprocket set 504. The driving block 505 is threadedly connected to the circumferential surface of the threaded rod 502, and the adjusting block 506 is fixedly connected to the lower end of the driving block 505. The clamping plate 507 is slidably connected in the adjusting block 506 through a guide rod. A bidirectional electric push rod 508 is fixedly connected to the upper end of the adjusting block 506, and the output end of the bidirectional electric push rod 508 is fixedly connected to the clamping plate 507 through a connecting frame 509.

[0043] In actual application of the embodiment of the present invention, when the pipe cutting position passes the laser cutting gun 2, the displacement motor 503 is controlled to rotate and drive the threaded rod 502 to rotate, and then the driving block 505 can drive the adjustment block 506 to move, so that the adjustment block 506 moves to the center point of the cutting position, and then the two-way electric push rod 508 is controlled to operate, and the clamping plate 507 can be driven to move inward under the action of the connecting frame 509, and then the pipe can be clamped by the clamping plate 507. When the pipe is cut later, the pipe at the cut position can be prevented from falling, and the stability of the pipe cutting can be improved. After the pipe is cut, the threaded rod 502 can be rotated again to control the cut pipe to move to the unloading position, and then the clamping plate 507 can be opened to make the cut pipe fall downward, completing the unloading of the pipe.

[0044] In one case of an embodiment of the present invention, the adjustment block 506 is moved to the center point of the pipe cutting part, that is, the clamping plate 507 is moved to the center point of the length of the pipe cutting part, and the length of the pipe cutting has certain restrictions, the shortest length is not less than the length of the clamping plate 507, and the longest distance is not higher than the width of the conveyor belt 5013, and the length of the clamping plate 507, the width of the conveyor belt 5013 and the dimensions of related components can be replaced in specifications and dimensions according to usage requirements.

[0045] like Fig.10 As shown, as another preferred embodiment of the present invention, a plurality of second ball grooves 5010 are formed on the clamping surface of the clamping plate 507 , and second balls 5011 are disposed in each of the second ball grooves 5010 .

[0046] In actual application of the embodiment of the present invention, when the clamping plate 507 clamps the tube, the second ball 5011 will come into contact with the ball, and the tube at the cut portion can rotate in the clamping plate 507 through the action of the second ball 5011, so that the rotation effect of the tube will not be affected when the tube is cut and clamped.

[0047] like Fig. 9 As shown, as another preferred embodiment of the present invention, a conveying frame 5012 is arranged at the upper end of the machine base 1, and a conveying belt 5013 is rotatably connected to the conveying frame 5012 through a connecting roller, and a plurality of convex strips 5014 are arranged on the surface of the conveying belt 5013.

[0048] In actual application of the embodiment of the present invention, the pipe at the cut portion clamped by the clamping plate 507 is moved to the upper end of the conveyor belt 5013, and then the clamping plate 507 is opened. At this time, the pipe at the cut portion will fall onto the conveyor belt 5013, and the conveyor belt 5013 will carry out subsequent transportation and transfer. In the process of conveying the pipe, the convex strips 5014 set on the surface of the conveyor belt 5013 can prevent the pipe on the conveyor belt 5013 from rotating, thereby improving the stability during transportation.

[0049] In one case of an embodiment of the present invention, the lengths of the conveyor frame 5012 and the conveyor belt 5013 can be set according to usage requirements and are not limited to a certain size.
