Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser pipe cutting machine, in particular to a three-chuck laser pipe cutting machine and cutting method. BACKGROUND

[0002] Laser pipe cutting machine, as an advanced metal processing equipment, is mainly applied to the cutting processing of various pipe materials. Whether it is round pipe or square pipe, this machine can provide precise cutting operation. Its biggest advantage is high precision and fast cutting ability, which makes laser pipe cutting machine gradually replace traditional cutting equipment in the field of metal processing. Compared with traditional cutting technology, laser pipe cutting not only has fast cutting speed, but also has very high cutting precision, almost no error.

[0003] Most of the existing cutting machines have limitations in design, especially in the adjustment of cutting angle. For example, the patent number CN115647612A is taken as an example. Although this machine is equipped with a transverse cutting displacement device to improve the flexibility and accuracy of cutting, it does not consider more complex application scenarios. Lack of inclination and rotation angle adjustment function. In many cases, such as bevel cutting or cutting at a specific angle, this limitation is particularly important. Without the corresponding angle adjustment device, the operator will encounter difficulties when using this machine to perform special angle cutting tasks, and the expected cutting effect cannot be achieved. This not only limits the application range of the machine, but also may cause waste of materials or decline in processing quality. SUMMARY

[0004] The purpose of the present application is to provide a three-chuck laser pipe cutting machine and cutting method to solve the problems raised in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a three-chuck laser tube cutting machine, comprising a first mounting plate, wherein a plurality of third rotating seats are fixedly arranged in a rectangular pattern on one side of the first mounting plate, and second rotating seats are fixed between the third rotating seats on the side of the first mounting plate, and a first telescopic rod is sleeved on each third rotating seat, and another identical third rotating seat is sleeved on the end of each first telescopic rod away from the third rotating seat, and a second mounting plate is fixed to the side of the other third rotating seat, wherein a first rotating seat is provided on the side of the second mounting plate close to the first mounting plate, and a plurality of second telescopic rods are sleeved at the four corners of the first mounting plate, wherein a fixing ear is sleeved on one end of each second telescopic rod, and an angle adjustment plate is fixed between the fixing ears, a fixing block is fixed on one side of the adjustment plate, and a fixing element is fixed on the side of the fixing block. The motor has a gear mounted on its output end. An angle plate meshes with the side of the gear. A main limiting block is located on the side of the angle plate near the angle adjustment plate. Several secondary limiting blocks are located on both sides of the main limiting block on the angle plate. A third mounting plate is fixed on the side of the secondary limiting blocks and the main limiting block away from the angle plate. The cutting head body is located on the side of the third mounting plate away from the main limiting block. The first telescopic rod, in conjunction with the first rotary seat and the second rotary seat, adjusts the vertical tilt angle of the second mounting plate by extending and retracting the first telescopic rod. The second telescopic rod, mounted on the second mounting plate, pushes the angle adjustment plate fixed on the fixed ear to move, causing the cutting head to move laterally and providing a cutting path for the cutting head along the direction of the bed body. The motor drives the gear to rotate, thereby pushing the angle plate to rotate, causing the cutting head to rotate.

[0006] Preferably, the first mounting plate has a housing on one side, and the housing has several slots on its side. The housing is used to protect the structure mounted on the first mounting plate and prevent the device from being touched by the operator during operation. The slots on the housing facilitate the wire harness on the cutting head body to pass through, thus avoiding obstructing the wire harness and hindering the movement of the cutting head body.

[0007] Preferably, the angle adjustment plate has a first groove with a certain curvature, and several smaller second grooves are provided on both sides of the first groove. A main limiting block is fitted inside the first groove, and a secondary limiting block is fitted inside the second groove. The curvature of the first and second grooves is coordinated with the main and secondary limiting blocks to rotate around the object being cut when they move.

[0008] Preferably, one side of the angle plate is hollowed out to prevent the angle plate from being obstructed by the second telescopic rod during movement.

[0009] Preferably, the second mounting plate has a through hole of the same size as the motor and the fixing block at the position of the motor, to prevent the motor and the fixing block from being obstructed by the second mounting plate when they move with the angle adjustment plate.

[0010] Preferably, the first mounting plate is fixed on the second chuck, and the second chuck has a first chuck and a third chuck on both sides. The first chuck and the third chuck are respectively clamped at both ends of the bed body, and the second chuck is clamped in the middle of the bed body. The first chuck and the second chuck, together with the third chuck, fix the item to be cut so that the cutting head can cut it.

[0011] Preferably, a second rotating seat is provided between the first rotating seats, and the two cooperate with each other to ensure that the second mounting plate can only be adjusted by tilting up and down.

[0012] The cutting method of a three-chuck laser tube cutter described above includes the following steps:

[0013] Step 1: Several first telescopic rods are divided into upper and lower groups. The upper and lower angles of the second mounting plate are adjusted by extending one group of the first telescopic rods and retracting the other group, so as to tilt the second telescopic rods.

[0014] Step 2: The angle adjustment plate fixed on the fixed ear is moved by extending or retracting the second telescopic rod, providing the cutting head with a cutting path along the direction of the bed body.

[0015] Step 3: The motor rotates, driving the gear to rotate, which in turn pushes the angle plate to move along the first and second slides, causing the third mounting plate to rotate, providing a rotation angle for the cutting head to cut.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention achieves multi-angle adjustment of the cutting head through a first telescopic rod, a second telescopic rod, a motor, gears, an angle plate, an angle adjustment plate, and a third mounting plate. The improved device significantly enhances the flexibility of the cutting angle, allowing for more precise adjustments. This not only enables the device to handle the cutting needs of a wider variety of materials but also ensures the efficiency and safety of the cutting process, greatly reducing material loss and waste. Furthermore, this improvement expands the device's application scenarios, enabling its use in more fields, including the precision machining of some special materials. This versatility further meets the diverse cutting needs of users. Attached Figure Description

A plurality of second telescopic rods 9 are fitted at the four corners of the first mounting plate 2. Each second telescopic rod 9 has a fixing ear 19 fitted at one end, and an angle adjusting plate 8 is fixed between the fixing ears 19. A fixing block 20 is fixed to one side of the adjusting plate, and a motor 11 is fixed to the side of the fixing block 20. The motor 11 outputs... A gear 10 is fitted at the end, and an angle plate 14 meshes with the side of the gear 10. A main limiting block 12 is provided on the side of the angle plate 14 near the angle adjusting plate 8. Several secondary limiting blocks 13 are provided on both sides of the main limiting block 12 on the angle plate 14. A third mounting plate 6 is fixed on the side of the secondary limiting blocks 13 and the main limiting block 12 away from the angle plate 14. A cutting head body 7 is provided on the side of the third mounting plate 6 away from the main limiting block 12. The first telescopic rod 4, in conjunction with the first rotating seat 15 and the second rotating seat 17, adjusts the up and down tilt angle of the second mounting plate 5 by telescopically extending and retracting the first telescopic rod 4. The second telescopic rod 9 fitted on the second mounting plate 5 pushes the angle adjusting plate 8 fixed on the fixing ear 19 to move, thereby causing the cutting head to move laterally and providing a cutting path for the cutting head along the direction of the bed body 1. The motor 11 drives the gear 10 to rotate, thereby pushing the angle plate 14 to rotate, causing the cutting head to rotate.

[0030] Furthermore, a housing 3 is provided on one side of the first mounting plate 2. Several slots are provided on the side of the housing 3. The housing 3 is used to protect the structure installed on the first mounting plate 2 and prevent the device from being touched by the operator during operation.

When the curvature of the first slide groove 21 and the second slide groove 22 is coordinated with the main limiting block 12 and the secondary limiting block 13, they rotate around the object being cut.

[0032] Furthermore, one side of the angle plate 14 is hollowed out to prevent the angle plate 14 from being obstructed by the second telescopic rod 9 during movement.

[0033] Furthermore, the second mounting plate 5 has a through hole 16 of the same size as the motor 11 and the fixing block 20 at the position of the motor 11, to prevent the motor 11 and the fixing block 20 from being obstructed by the second mounting plate 5 when they move with the angle adjustment plate 8.

[0034] Furthermore, the first mounting plate 2 is fixed on the second chuck. The second chuck has a first chuck and a third chuck on both sides.

[0035] Furthermore, a second rotating base 17 is provided between the first rotating bases 15, and the two cooperate with each other to ensure that the second mounting plate 5 can only be adjusted by tilting up and down.

[0036] The cutting method of a three-chuck laser tube cutter described above includes the following steps:

[0037] Step 1: Several first telescopic rods are divided into upper and lower groups. The upper and lower groups of first telescopic rods 4 are used to adjust the upper and lower angles of the second mounting plate 5 by extending one group and retracting the other group, so as to tilt the second telescopic rod 9.

[0038] Step 2: The angle adjustment plate 8 fixed on the fixed ear 19 is moved by extending or retracting the second telescopic rod 9 to provide a cutting path for the cutting head along the direction of the bed body 1.

[0039] Step 3: The rotation of motor 11 drives gear 10 to rotate, thereby pushing angle plate 14 to move along the first slide groove 21 and the second slide groove 22, driving the third mounting plate 6 to rotate, providing a rotation angle for the cutting head to cut.

[0040] In summary, this device includes a first mounting plate 2 with several third rotating seats 18 fixed on it, and a second rotating seat 17 fixed on its side. Each third rotating seat 18 is fitted with a first telescopic rod 4, and another third rotating seat 18 is provided on the other side, with a second mounting plate 5 fixed to its side. The second mounting plate 5 has a first rotating seat 15 on the side closest to the first mounting plate 2. The several first telescopic rods 4 are divided into upper and lower groups, which push the third rotating seats 18 respectively to adjust the vertical tilt angle of the second mounting plate 5.

[0041] Second telescopic rods 9 are fitted at the four corners of the first mounting plate 2, with fixed ears 19 fitted at one end. Angle adjustment plates 8 are fixed between the fixed ears 19. The second telescopic rods 9 push the angle adjustment plates 8 fixed between the fixed ears 19 to move, providing a cutting path for the cutting head along the bed body 1. A motor 11 and a gear 10 are fixed on the angle adjustment plate 8. The gear 10 meshes with an angle plate 14, which has a main limiting block 12 and a secondary limiting block 13. The cutting head body 7 is located on the side of the third mounting plate 6 away from the main limiting block 12. The motor 11 drives the gear 10 to rotate, pushing the angle plate 14 to rotate, thereby driving the third mounting plate 6 fixed to the sides of the main limiting block 12 and the secondary limiting block 13 to move, providing rotational tilt for the cutting head, and ultimately enabling the cutting head to generate multi-directional cutting angles.

[0042] It is worth noting that the entire device is controlled by a central control unit. Since the equipment matched with the control unit is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
