Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel pipe processing equipment, specifically to a laser-guided flat-end device for stainless steel pipes. Background Technology

[0002] Currently, with the booming development of the automotive industry, the quality requirements for stainless steel pipes used in automobiles are becoming increasingly stringent, and the demand is also growing. The requirements for controlling process costs and ensuring product consistency are also increasing. Therefore, improvements and optimizations are needed in the stainless steel pipe processing technology. For example, CN219581912U describes a stainless steel pipe cutting machine, including a frame with a fixing device for securing the stainless steel pipe. A vertically oriented laser cutting head is horizontally slidably mounted on the frame via an installation device, positioned above the stainless steel pipe, with the sliding direction of the laser cutting head forming an acute angle with the length direction of the stainless steel pipe. However, this single-station design requires the operator to perform clamping, positioning, and cutting sequentially, resulting in significant downtime and slow processing speed, making it difficult to meet the demands of mass production. Furthermore, traditional equipment relies on manual visual adjustment of the cutting position and depth, making it difficult to guarantee cutting accuracy. This leads to large errors in pipe length and the presence of burrs or unevenness on the cut surface, affecting product quality. Frequent manual intervention increases labor costs, and the operator's workload is high. Metal chips and slag generated during the cutting process easily accumulate in the processing area, affecting equipment operation and increasing the frequency of manual cleaning.

[0027] The pneumatic rotary chuck 7 includes: a pneumatic rotary chuck base 701 fixed on the worktable 1, a hole in the center of the pneumatic rotary chuck base 701, a pneumatic rotary gripper 702 at the front end of the pneumatic rotary chuck base 701, the pneumatic rotary gripper 702 being connected to the pneumatic rotary chuck base 701 via bearings, a drive gear 703 at the rear end of the pneumatic rotary chuck base 701 being fixedly connected to the pneumatic rotary gripper 702 and rotating coaxially, and a pneumatic rotary motor 704 above the pneumatic rotary chuck base 701, the output end of the pneumatic rotary motor 704 being meshed with the drive gear 703 via a planetary gear set.

[0028] Among them, the pneumatic rotary gripper 702 clamps the stainless steel pipe by pneumatic drive, ensuring that the pipe remains stable during processing. The pneumatic rotary motor 704 drives the pneumatic rotary gripper 702 to rotate through the drive gear 703, adapting to the cutting requirements of different angles, ensuring that the end face of the pipe is evenly stressed during laser cutting, and avoiding burrs or unevenness on the cut surface.

[0029] The front and rear motion mechanism 8 includes: a front and rear motion guide rail 801 fixed on the worktable 1; a front and rear motion motor 802 located behind the front and rear motion guide rail 801; a front and rear motion screw 803 located at the output end of the front and rear motion motor 802 extending into the front and rear motion guide rail 801; a front and rear motion slide 804 connected to the front and rear motion screw 803; the front and rear motion slide 804 engaging with the front and rear motion guide rail 801 and slidably connected to the front and rear motion guide rail 801; a rear positioning part 9 fixed at the front end of the front and rear motion slide 804; and a front and rear drag chain 805 located on the side; the other end of the front and rear drag chain 805 fixed on the worktable 1.

[0030] Among them, the front and rear motion motor 802 drives the front and rear motion slide 804 to move back and forth through the front and rear motion screw 803. Through the precise control of the front and rear motion mechanism 8, the length error of the pipe is ensured to be controlled within ±0.1mm.

[0031] The front slag receiving structure 10 includes: a front slag receiving bracket 1001, a telescopic rod 1002 connected to the front slag receiving bracket 1001, a connecting plate 1003 connected to the end of the telescopic rod 1002, the middle part of the connecting plate 1003 being connected to the front slag receiving bracket 1001 via a rotating shaft 1004, and a front fixing part 16 provided at the end of the connecting plate 1003.

[0032] The telescopic rod 1002 and the connecting plate 1003 can adjust the position of the front slag receiving structure according to the length of the pipe fitting to ensure that the waste material can fall accurately into the slag receiving area. The front positioning part 16 is located at the end of the front slag receiving structure 10 to assist in positioning the pipe fitting and ensure cutting accuracy.

[0033] When using this invention, the operator first inserts the stainless steel pipe to be processed into the dual-position pneumatic rotary chuck 7. The pneumatic rotary chuck 7 automatically clamps the pipe through the pneumatic rotary jaws 702, ensuring the pipe remains stable during processing. The rear positioning part 9 adjusts its position through the front-rear motion mechanism 8, ensuring the length accuracy of the pipe is controlled within ±0.1mm. The operator inputs the pipe specifications, such as pipe diameter, length, and cutting depth, through the human-machine interface controller 14. The system automatically adjusts the initial positions of the front-rear motion mechanism 8, the left-right motion mechanism 4, and the up-down motion mechanism 5, ensuring that the laser gun head 6 is aligned with the cutting position of the pipe. After the equipment is started, the laser gun head 6 begins to cut the end face of the pipe according to the preset path. The left-right motion mechanism 4 and the up-down motion mechanism 5 work together to drive the laser gun. The laser head 6 precisely cuts along the end face of the pipe fitting. The pneumatic rotary chuck 7 rotates the pipe fitting as needed during cutting to ensure a smooth, burr-free cut surface. Waste generated during cutting is automatically collected into the waste trough 12 via the front slag receiving structure 10 and the waste sliding groove 11. After cutting, the front slag receiving structure 10 is adjusted in position via the telescopic rod 1002 and connecting plate 1003 to ensure the waste completely slides into the waste sliding groove 11. The waste then enters the waste trough 12 through the sliding groove. The operator can periodically clean the waste trough. After cutting, the laser head 6 and the motion mechanism automatically return to their initial positions. The pneumatic rotary chuck 7 releases the processed pipe fitting, and the operator removes the finished product and places the next pipe fitting to be processed. The equipment then enters the next processing cycle. The dual-station design supports alternating operation of two stations, further improving efficiency.
