Description

Technical Field

[0001] The utility model relates to the field of laser cutting equipment, in particular to a laser cutting tooling for quartz tubes. Background Art

[0002] At present, the cutting of quartz tubes generally uses laser cutting instead of grinding wheel cutting to reduce dust and noise. However, a small amount of dust is still generated during laser cutting. Currently, a dust removal mechanism is set on the equipment body to collect dust. However, since the dust is mainly generated during the cutting of quartz tubes, if a dust removal mechanism is set on the equipment body, the distance between the dust removal mechanism and the quartz tube is relatively far. Moreover, the quartz tube is cut while exposed to the air, and the dust is likely to float out and pollute the environment and affect the health of the staff.

[0003] CN202222197266 discloses a numerically controlled laser cutting machine with a movable fixture, including a workbench. A support seat is fixedly connected to the top end of the workbench. A laser cutting probe is fixedly connected to the bottom end of the cross plate of the support seat. A moving clamping assembly and a dust removal assembly are further arranged on the top end of the workbench, and the dust removal assembly is located below the moving clamping assembly. The dust removal assembly includes a fixed seat fixedly connected to the top end of the workbench, a third electric push rod fixedly connected to the inner side wall of the fixed seat, a moving plate fixedly connected to the telescopic end of the third electric push rod, and a cleaning brush fixedly connected to the bottom end of the moving plate. This numerically controlled laser cutting machine collects the dust and debris floating on the workbench by setting a cleaning brush at the bottom end of the moving plate. However, during laser cutting, since the numerically controlled laser cutting machine is open, some dust and debris may float to the outside and pollute the environment.

[0004] The technical problem to be solved by the utility model is: how to improve the dust removal effect during the cutting of quartz tubes. Summary of the Utility Model

[0024] In this embodiment, this quartz tube laser cutting tooling is placed on the workbench of an external laser device, and then the quartz tube 7 is placed on the driving unit 2, and the quartz tube 7 is located in the receiving cavity 4. The staff adjusts the position of the quartz tube 7 so that the laser head of the external laser device is aligned with the quartz tube 7, and the driving unit 2 is started. The driving unit 2 drives the quartz tube 7 to rotate around its own axis, so that the laser can cut along the outer circumference of the quartz tube 7, and then cut off the quartz tube 7.

[0025] It should be noted that by providing the protective cover 3 on the fixed seat 1, the dust generated by laser cutting can be surrounded by the protective cover 3, initially preventing the dust from floating to the outside. Secondly, by providing the dust removal module 5 on the protective cover 3 to suck and collect the dust in the protective cover 3, the dust is further prevented from floating to the outside. Through the synergistic effect of the protective cover 3 and the dust removal module 5, the dust removal effect of laser cutting can be greatly improved.

[0026] The dust removal module 5 can be a commercially available dust suction device. The protective cover 3 is provided with a mounting flange, and the dust removal module 5 is fixed on the protective cover 3 through the mounting flange and is communicated with the receiving cavity 4.

[0027] Preferably, the protective cover 3 is composed of a first side plate 31 , a top plate 32 , and a second side plate 33 ; one end of the top plate 32 is connected to the first side plate 31 , and the other end is hinged to the second side plate 33 ; the first side plate 31 is connected to the fixing seat 1 .

[0028] In this embodiment, the first side plate 31, the top plate 32, and the second side plate 33 are assembled into the protective cover 3 by screws, and both ends of the protective cover 3 are open sides, which is convenient for placing quartz tubes 7 of different lengths. The staff can open the second side plate 33 and then place the quartz tube 7 on the driving unit 2 to avoid taking out the quartz tube 7 from both ends of the protective cover 3 and causing wear of the quartz tube 7.

[0029] Preferably, the top plate 32 is provided with a through hole 321 for facilitating the laser to pass through the protective cover 3 ; and the second side plate 33 is provided with a handle 331 .

[0030] In this embodiment, a through hole 321 is provided on the top plate 32, so that the laser head of an external laser device can pass through the top plate 32 to laser cut the quartz tube 7. A handle 331 is provided on the second side plate 33, so that the staff can open the second side plate 33 easily.

[0031] Preferably, the driving unit 2 includes symmetrically arranged rollers 21 and a first driving module 22 for driving the rollers 21 to rotate; the symmetrically arranged rollers 21 are all rotatably connected to the fixing base 1; and the quartz tube 7 is placed on the symmetrically arranged rollers 21.

[0032] In this embodiment, the symmetrically arranged rollers 21 are arranged on the fixing seat 1 and are located in the accommodating chamber 4. The first driving module 22 is connected to the rollers 21 through a synchronous belt. The staff places the quartz tube 7 on the symmetrically arranged rollers 21, and the first driving module 22 drives the rollers 21 to rotate, thereby driving the quartz tube 7 to rotate around its own axis. The quartz tube 7 rotates while the laser head does not move, thereby realizing the laser cutting of the quartz tube 7. In this way, after the quartz tube 7 is cut, the rollers 21 can support the quartz tube 7 to prevent the quartz tube 7 from falling outside the external laser device.

[0033] The first driving module 22 is a motor.

[0034] Preferably, the quartz tube laser cutting tool further comprises a transverse adjustment unit 6 ; the transverse adjustment unit 6 is used to adjust the relative position of the fixing seat 1 and the laser head of the peripheral device; the fixing seat 1 is slidably connected to the transverse adjustment unit 6 .

[0035] In this embodiment, when the quartz tube laser cutting tool is used for cutting for the first time or when a quartz tube 7 of a different diameter is replaced for cutting, the relative position of the fixing seat 1 and the external laser head can be adjusted through the lateral adjustment unit 6 so that the laser head is located on the axis of the quartz tube 7 to cut the quartz tube 7, thereby ensuring the laser cutting effect.

[0036] Preferably, the lateral adjustment unit 6 includes a base 61 and a second drive module 62 disposed on the base 61; the fixed seat 1 is slidably connected to the second drive module 62.

[0037] In this embodiment, the base 61 is fixed on the workbench of the peripheral laser device, and the second drive module 62 drives the fixed seat 1 to move, thereby driving the quartz tube 7 to move, so that the laser head is aligned with the axis of the quartz tube 7.

[0038] Preferably, the lateral adjustment unit 6 further includes a locking module 63 disposed on the base 61; the second drive module 62 is a lead screw 621 and a hand wheel 622; the lead screw 621 is rotatably connected to the base 61; the fixed seat 1 is slidably connected to the lead screw 621; the hand wheel 622 is connected to one end of the lead screw 621; the locking module 63 is used to limit the rotation of the lead screw 621.

[0039] In this embodiment, the lead screw 621 is rotatably connected to the base 61 through a bearing seat. A nut is provided on the lead screw 621, and the fixed seat 1 is slidably connected to the lead screw 621 through the nut. The hand wheel 622 is fixed to the end of the lead screw 621. The locking module 63 is a optical axis fixed seat 1 and an adjustable handle screw. The optical axis fixed seat 1 is disposed on the base 61. The end of the lead screw 621 passes through the optical axis fixed seat 1 and is connected to the hand wheel 622. The adjustable handle screw is disposed on the optical axis fixed seat 1. The staff rotates the adjustable handle screw to enable the lead screw 621 to rotate within the optical axis fixed seat 1, and then rotates the hand wheel 622 to drive the lead screw 621 to rotate, thereby driving the fixed seat 1 to move, so that the laser head is aligned with the axis of the quartz tube 7. After the adjustment is completed, the adjustable handle screw is rotated to clamp the lead screw 621 by the optical axis fixed seat 1, avoiding the lead screw 621 from rotating due to vibration during the laser cutting process, and further changing the relative position between the laser head and the quartz tube 7.

[0040] Preferably, the protective cover 3 is a protective cover 3 made of acrylic.

[0041] In this embodiment, the transparent acrylic protective cover 3 is adopted, which is convenient for the staff to observe the cutting condition of the quartz tube 7 in real time and avoid safety accidents.

[0042] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
