Description

Technical Field

[0001] The invention belongs to the technical field of pipe cutting machines, in particular to a pipe cutting machine chuck and a laser pipe cutting machine. Background Art

[0002] Laser tube cutting machine is a new type of tube cutting equipment, which uses high energy density laser beam as heat source to cut tubes, and has the advantages of fast cutting speed, high production efficiency, high cutting surface quality, etc. With the continuous development of laser technology and CNC technology, laser tube cutting machine has become an advanced processing equipment in the field of industrial tube cutting.

[0003] In the prior art, when the tube cutting machine chuck is limiting the position of the tube, there is a problem that the resistance end is high in strength. If the resistance end does not have good resistance force, it will cause looseness during the tube cutting process of the laser tube cutting machine, thereby causing cutting deviation. If the resistance end provides good resistance force, it will cause the tube to be squeezed and dented.

[0004] After searching, it is found that a laser tube cutting machine chuck and a laser tube cutting machine (publication number: CN113199162A) are disclosed in a Chinese patent document. The present invention relates to a laser tube cutting machine chuck and a laser tube cutting machine. The laser tube cutting machine chuck comprises a rotating disk, a first slide bar, a second slide bar, a third slide bar, a fourth slide bar and four groups of claw assemblies. Each claw assembly comprises a slide table, a roller assembly, a cylinder and a linear slide rail assembly. The roller assembly is fixedly arranged on the slide table. Each slide table is matched with the cylinder transmission. The two ends of the slide table are respectively matched with the first slide bar and the third slide bar or the second slide bar and the fourth slide bar. A linear slide rail assembly is arranged on the top surface or the bottom surface of the cylinder. The linear slide rail assembly comprises a sliding block and a slide rail that are matched with each other. The slide rail is fixedly arranged on the cylinder. A connecting rod that is matched with each other for rotation is arranged at both ends of each slide table. The other end of each connecting rod is respectively matched with each other for rotation on one side of the adjacent cylinder slide block, so that the two connecting rods on the same slide table are distributed in an eight-shaped shape, and the two connecting rods on the same slide block are distributed in an eight-shaped shape. However, the following defects still exist:

[0005] Although the above-mentioned laser tube cutting machine chuck and laser tube cutting machine ensure that the roller assemblies symmetrically arranged in pairs can be adjusted synchronously, and ensure that the spacing between the center lines of the rotating disk and the two groups of roller assemblies symmetrically are always the same, thereby improving the adjustment accuracy, there is still a problem that due to the high strength of the resistance end, if the resistance end does not have a good resistance force, it will lead to looseness during the tube cutting process of the laser tube cutting machine, thereby causing cutting deviation.

Through the mounting tube 5, in the process of limiting one end of the tube by the tube cutting machine chuck body 1, the four mounting tubes 5 all move toward the center point of the tube cutting machine chuck body 1 until the balloon block 6 contacts the outer wall of the tube, so that the abutment protrusion 8 is forced to contact the outer wall of the tube, and then the balloon block 6 is inflated by the air pump 9 to harden the balloon block 6, so that the outer wall of the balloon block 6 fits with the outer wall of the tube, thereby completing the limiting of the tube.

[0036] Specifically, one end of the pipe cutting machine chuck body 1 is fixedly connected to the mounting shell 10 through a flange, and four rotating chambers 18 are fixedly connected inside the mounting shell 10 at equal intervals, and the rotating wheels 17 are movably connected inside the rotating chambers 18, one end of the rotating wheel 17 is fixedly connected to one end of the first transmission screw 11, and the four first transmission screws 11 correspond to the guide slide rails 2 one by one, and the four first transmission screws 11 are arranged in a cross-shaped structure, and the outer side walls of the first transmission screws 11 are meshed and connected with connecting screw sleeves, and the outer side walls of the connecting screw sleeves are fixed to the other end of the guide slider 3, the thread teeth of the left and right first transmission screws 11 are arranged in opposite structures, and the thread teeth of the upper and lower first transmission screws 11 are arranged in the same structure, and the four first transmission screws 11 rotate synchronously, so that the four first transmission screws 11 and the connecting screw sleeve constitute a screw transmission structure, thereby driving the guide slider 3 to move synchronously with the center of the pipe cutting machine chuck body 1, thereby synchronously driving the mounting seat 4 and the mounting tube 5 and other components.

[0037] Furthermore, one end of the left first transmission screw 11 is fixedly connected to one end of the first bevel gear 12, and the other end of the first bevel gear 12 is fixedly connected to one end of the connecting gear 14 through a connecting rod. One end of the right first transmission screw 11 close to the connecting gear 14 is fixed to the other end of the connecting gear 14 through a transmission rod. One end of the connecting gear 14 is meshedly connected to the outer wall with a transmission gear 15, and one end of the transmission gear 15 is connected to the output end of the motor 16 through a coupling.

In this way, during use, the transmission gear 15 is rotated by the output of the motor 16, and then drives the meshing connecting gear 14 to rotate synchronously. In this way, the first bevel gear 12 and the first transmission screw rod 11 on the right side are rotated by the rotation of the connecting gear 14, and then the first bevel gear 12 is rotated to drive the first transmission screw rod 11 on the left side to rotate, and the meshing second bevel gear 13 is rotated, and finally the second bevel gear 13 drives the connected first transmission screw rod 11 to rotate, thereby realizing the synchronous rotation of the four first transmission screw rods 11.

[0038] Furthermore, a bendable and adjustable bellows 35 is fixedly connected to the top of the mounting shell 10, and the end of the bellows 35 away from the mounting shell 10 is fixedly connected to a connecting seat 36, and the end of the connecting seat 36 away from the bellows 35 is threadedly connected with a threaded adjustment rod 37, and one end of the threaded adjustment rod 37 is fixedly connected to a limiting block, and the other end of the threaded adjustment rod 37 is fixedly connected to a mounting plate 38, and the end of the mounting plate 38 away from the threaded adjustment rod 37 is fixedly connected with a connecting balloon 39 with a "concave" structure, and a vibration sensor 40 for collecting vibration parameter data of the pipe is fixedly connected inside the groove of the connecting balloon 39. Through the bellows 35, during use, the bellows 35 can be bent and adjusted to a suitable position according to requirements such as the pipe size, and then the threaded adjustment rod 37 is rotated to make the mounting plate 38, the connecting balloon 39 and other components movable and adjusted until the vibration sensor 40 conflicts with the outer wall of the pipe, and then the vibration parameter data of the pipe is monitored by the vibration sensor 40.

[0039] Principle and process of the present invention:

[0040] First, by setting the mounting tube 5, in the process of limiting one end of the pipe by the pipe cutting machine chuck body 1, one end of the pipe is placed in the center of the pipe cutting machine chuck body 1;

[0041] Secondly, the transmission gear 15 is set, so that during use, the transmission gear 15 is rotated by the output of the motor 16, and then drives the meshing connecting gear 14 to rotate synchronously, so that the first bevel gear 12 and the first transmission screw 11 on the right are driven to rotate by the rotation of the connecting gear 14, and then the first bevel gear 12 is driven to rotate the first transmission screw 11 on the left and the second bevel gear 13 to be meshed is driven to rotate, and finally the second bevel gear 13 drives the connected first transmission screw 11 to rotate, so that the four first transmission screws 11 are rotated synchronously;

[0042] Then, when the four first transmission screws 11 rotate synchronously, the four first transmission screws 11 and the connecting screw sleeve form a screw transmission structure, thereby driving the guide slider 3 to move synchronously with the center of the pipe cutting machine chuck body 1, thereby synchronously driving the mounting seat 4, the mounting pipe 5 and other components;

[0043] Then, the four mounting tubes 5 are synchronously moved toward the center point of the tube cutting machine chuck body 1 until the four balloon blocks 6 are in contact with the outer wall of the tube, so that the contact protrusions 8 are forced to contact the outer wall of the tube, and then the air pumps 9 are started to slowly inflate each balloon block 6 at the same time to ensure that the inflation amount of the balloon blocks 6 does not float too much, so that the outer wall of the balloon block 6 is in contact with the outer wall of the tube, thereby completing the position limiting of the tube;

[0044] Finally, by setting the bellows 35, during use, according to the requirements of the pipe size, the bellows 35 is bent and adjusted to a suitable position, and then the threaded adjustment rod 37 is rotated to adjust the mounting plate 38 and the connected balloon 39 and other components until the vibration sensor 40 conflicts with the outer wall of the pipe, and then the vibration parameter data of the pipe is monitored by the vibration sensor 40. When the monitored vibration is greater than the set floating threshold, it means that the clamping is not good, and excessive vibration frequency will cause looseness. Therefore, the staff can discover and adjust it in time, so it is necessary to adjust the balloon block 6 and other components in a targeted manner. The limiting force of such a pipe cutting machine chuck is completed. It should be noted that this embodiment is a pipe cutting machine chuck. The components are all universal standard parts or components known to technical personnel in this field. The structure and principle are known to technical personnel in this field through technical manuals or through conventional experimental methods.

In this way, the potential energy released by the reset spring 30 drives the connecting sleeve rod 28 to move, thereby making the transfer roller 29 contact with the outer wall of the pipe. Since the transfer roller 29 is movable, the pipe can be moved horizontally. At the same time, after the transfer roller 29 contacts, the electromagnetic block 27 is energized to magnetically limit the connecting sleeve rod 28 with the magnetic attraction structure.

[0046] Specifically, both sides of the operating table 20 are fixedly connected with a guide slot 21 with a "convex" structure provided on the inner side wall, and the inner side wall of the guide slot 21 is movably connected with a guide movable block 22 provided with a "convex" structure, one of the guide movable blocks 22 is fixedly connected with a transmission screw sleeve 31 through the inside, and the inner side wall of the transmission screw sleeve 31 is meshedly connected with a second transmission screw 32, both ends of the second transmission screw 32 are fixedly connected with a limiting wheel 33 movably connected inside the limiting cavity, and one of the limiting wheels 33 is connected to the guide slot 21 through a linkage rod. The adjusting knob 34 on one end of the outer side is fixedly connected to the other end. By setting the adjusting knob 34, when the positions of the movable seat 23, the mounting ring 25 and other parts need to be adjusted during use, the adjusting knob 34 is rotated forward or reversely to drive the second transmission screw 32 to rotate forward or reverse synchronously, so that the second transmission screw 32 cooperates with the transmission screw sleeve 31 to form a screw transmission structure, driving the guide movable block 22 to move left or right, and finally adjusting the positions of the movable seat 23, the mounting ring 25 and other parts to a suitable position.

[0047] Furthermore, the top of the guide movable block 22 is fixedly connected to a movable seat 23, and the top of the movable seat 23 is fixedly connected to a mounting ring 25.

The movable seat 23 is coordinated with the mounting ring 25 and other components. In this way, the position of the mounting ring 25 and other components can be adjusted by adjusting the movable seat 23 during use. In this way, during the laser pipe cutting machine body 19 cutting the pipe, it can provide good stability and can be adjusted in real time according to the size of the pipe, thereby providing good stability for all pipes during the pipe cutting process.

[0048] Principle and process of the present invention:

[0049] First, the pipe to be processed is passed through all the mounting rings 25 and one end thereof is fixed to the pipe cutting machine chuck body 1;

[0050] Secondly, by rotating the adjusting knob 34 forward or reversely, the adjusting knob 34 drives the second transmission screw 32 to rotate forward or reverse synchronously, so that the second transmission screw 32 cooperates with the transmission screw sleeve 31 to form a screw transmission structure, driving the guide movable block 22 to move left or right, and finally adjusting the positions of the movable seat 23 and the mounting ring 25 and other components to the appropriate positions;

[0051] Afterwards, through the provided mounting ring 25, one end of the pipe to be cut by the chuck body 1 of the pipe cutter is passed through the mounting ring 25, and then the potential energy released by the reset spring 30 drives the connecting sleeve 28 to move, so that the transfer roller 29 contacts the outer wall of the pipe, and because the transfer roller 29 is movable, the pipe can be moved horizontally, and at the same time, after the transfer roller 29 contacts, the electromagnetic block 27 is energized to magnetically limit the connecting sleeve 28 provided in the magnetic attraction structure;

[0052] Finally, the laser tube cutting machine body 19 outputs the operation and completes the laser cutting of the tube. In this way, the use of the laser tube cutting machine is completed.
