Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser processing equipment, in particular to a gantry type three-dimensional five-axis laser processing equipment. BACKGROUND

[0002] At present, when cutting special-shaped pipe fittings, the raw materials need to be placed in the cutting tool for processing. Different products require different tooling, and the tooling production cost is high. Moreover, it is highly dependent on manual work, resulting in heavy manual workload. The cutting position and fixing position need to be adjusted multiple times, the operation process is complex, and the cutting precision and efficiency are also reduced.

[0003] Chinese patent CN 217799666 U discloses a special-shaped pipe fitting laser cutting equipment, which comprises a workbench, a cutting mechanism and a feeding mechanism. The cutting mechanism comprises a rack and a laser cutting head. The rack is installed on the workbench, and the laser cutting head is installed on the rack. A rotating member for driving the laser cutting head to rotate around a horizontal axis and a moving member for driving the laser cutting head to move in a direction perpendicular to the horizontal axis are arranged on the rack. The feeding mechanism comprises a special-shaped pipe fitting placing table for placing the pipe fittings to be cut and a feeding manipulator for clamping the pipe fittings to be cut on the special-shaped pipe fitting placing table. The special-shaped pipe fitting placing table and the feeding manipulator are both installed on the workbench. The above-mentioned special-shaped pipe fitting laser cutting equipment can realize automatic continuous production and greatly improve the production efficiency. However, in actual application, the feeding manipulator is limited by its joint structure, forming a machining dead angle on the machining position of the special-shaped pipe fitting, which cannot be directly machined. At this time, the feeding manipulator needs to release the special-shaped pipe fitting, and then the clamping position is adjusted manually. After that, the feeding manipulator re-clamps the special-shaped pipe fitting to realize cutting machining. However, this may easily cause the cutting machining position of the special-shaped pipe fitting to deviate, affecting the product quality. SUMMARY

[0067] In practical application, the controller controls the follow-up driver 592 to work according to the distance information detected by the capacitive sensor. Specifically, a distance threshold is stored in the controller, when the current distance detected by the capacitive sensor is less than the distance threshold, the controller controls the follow-up driver 592 to drive the follow-up lead screw 591 to rotate, so as to make the cutting head body 58 move upward; when the current distance detected by the capacitive sensor is greater than the distance threshold, the controller controls the follow-up driver 592 to drive the follow-up lead screw 591 to rotate, so as to make the cutting head body 58 move downward, so as to realize real-time follow-up adjustment of the distance between the cutting head body 58 and the surface of the special-shaped pipe fitting 200, which can effectively improve the cutting efficiency and also improve the cutting quality.

While the current special-shaped pipe fitting 200 is being cut, the operator can place another special-shaped pipe fitting 200 on the clamping assembly 64, and when the cutting of the current special-shaped pipe fitting 200 is completed, only the rotating table 62 needs to be controlled to rotate, that is, the positions of the current special-shaped pipe fitting 200 and another special-shaped pipe fitting 200 are switched, so as to realize non-stop feeding and effectively improve the production efficiency.

[0069] Please refer to Figure 6 The swing driver is fixedly arranged in the switching cross beam 63, the number of the swing drivers is two, the two swing drivers are separately arranged at two ends of the switching cross beam 63, the clamping assembly 64 is in transmission connection with the swing driver, the clamping assembly 64 corresponds to the swing driver in one-to-one manner, and the clamping assembly 64 swings ±180° in the vertical direction under the drive of the swing driver.

[0072] Please refer to Figure 7 and Figure 8 The gantry type three-dimensional five-axis laser processing equipment 100 further comprises a waste discharging mechanism 70. The waste discharging mechanism 70 comprises a support 71, an inclined upward conveying belt 72, a driving roller, a driven roller and a conveying driver 73. The driving roller and the driven roller are rotatably arranged on the support 71. The inclined upward conveying belt 72 is arranged outside the driving roller and the driven roller. The driven roller is in transmission connection with the driving roller through the inclined upward conveying belt 72. The conveying driver 73 is fixedly arranged on the support 71. The driving roller is in transmission connection with the conveying driver 73. The conveying driver 73 is a driving motor. The inclined upward conveying belt 72 is sequentially divided into a waste accumulation area 721, an upward inclined area 722 and a discharging area 723 according to the advancing direction. The waste accumulation area 721 is arranged below the rotary laser cutting head 50 and the pipe fitting clamping mechanism 60. In the cutting process, under the driving of the driving motor, the driving roller rotates in cooperation with the driven roller to drive the inclined upward conveying belt 72 to work. The cutting waste falls into the waste transport vehicle outside the device from the waste accumulation area 721, the upward inclined area 722 and the discharging area 723, thereby saving the labor intensity and effectively avoiding the waste accumulation to affect the normal working of the gantry type three-dimensional five-axis laser processing equipment 100, effectively reducing the downtime and improving the production efficiency.

The rotary laser cutting head 50 is close to the pipe clamping mechanism 60 through the cooperation of the Y-axis moving mechanism 20, the X-axis moving mechanism 30 and the Z-axis moving mechanism 40. The cutting angle of the cutting head body 58 is adjusted through the cooperation of the C-axis driving mechanism 54 and the B-axis driving mechanism 56. The processing position of the special-shaped pipe 200 is adjusted through the swing driving device. Therefore, the cutting head body 58 can process all the processing regions of the special-shaped pipe 200, and no processing dead angle is formed. Therefore, the position does not need to be adjusted again by manual operation in the processing process, the positioning accuracy is high, the cutting quality is effectively improved, the repeated accuracy of cutting processing is high, and the repeated accuracy is controlled within 5 μm.
