DETAILED DESCRIPTION

[0022] The technical scheme of the present application will be described clearly and completely in conjunction with the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all.

[0023] As shown in Figure 1 and 2 , the existing processing method for the inner wall of the forming hole of the pavement brick mold is to fix the robot 2 on the ground. At this time, the processing range of the laser processing head 13 is limited, and the adjustment range of the robot arm is not enough. Only the mold can be moved to cooperate. The pavement brick mold 3 itself is relatively large and is not convenient to carry, which leads to processing difficulty and cannot complete the additive processing of the inner wall of the forming hole of the pavement brick mold 3 at one time.

[0024] In order to expand the processing range of the laser processing head 13 while facilitating the movement of the pavement brick mold 3, a pavement brick mold additive manufacturing processing device is designed, as shown in Figure 3 , which comprises a laser processing module and a workpiece module. The laser processing module comprises a gantry 1 and a robot 2. The robot 2 is hung upside down on the top beam of the gantry 1. The workpiece module comprises a linear movement mechanism and a dividing disc 4 for placing the pavement brick mold 3. The dividing disc 4 is movably arranged below the gantry 1 through the linear movement mechanism.

[0025] The robot 2 is installed upside down on the gantry 1, and the laser processing head 13 is installed on the robot 2 through a connecting flange. During additive processing, the pavement brick mold 3 is placed on the rotatable dividing disc 4, and then the dividing disc 4 is pushed to move to below the laser processing head 13 along the linear movement mechanism. The inverted laser processing head 13 has a large processing range, and the movable mold can complete the processing at one time, improving the processing efficiency.

[0026] In order to facilitate the pushing of the mold, a handle 11 is further arranged on the base plate 7. The handle 11 is fixedly connected with the base plate 7 through a connecting rod 12, and the connecting rod 12 is inclined. The connecting rod 12 is fixedly connected with the base plate 7 and the handle 11 at both ends through screws. The base plate 7 is pushed and pulled forward and backward along the guide rail 5 by holding the handle 11, so as to cooperate with the processing of the laser processing head 13.

[0027] The robot 2 has a laser processing head 13 connected with the robot 2 through a connecting flange, in order to provide the laser processing head 13 with beam energy and metal powder, the laser processing module further comprises a laser 14, a water cooler 15, a powder feeder 16 and a voltage stabilizer 17 connected with the laser processing head 13. The water cooler 15 provides water cooling for the laser and the laser processing head, the powder feeder 16 provides metal powder for additive manufacturing of the laser processing, and the voltage stabilizer 17 provides stable voltage for all devices and provides a stable processing environment for additive manufacturing. The laser all-in-one machine integrates three functions of laser 14, robot control and general control. The laser 14 converts electrical energy into optical energy to provide beam energy for the laser processing head 13, the robot control programs the movement mode of the robot 2, and the general control includes laser power adjustment, powder feeder powder amount adjustment, powder feeder gas path switch and laser processing head protection gas adjustment.

The sliding blocks 6 of the two guide rails 5 are fixedly arranged above a bottom plate 7, the sliding blocks 6 are arranged on four corners of the bottom plate 7, and the index plate 4 is installed on the bottom plate 7. The cooperation of the two guide rails 4 and the four sliding blocks 6 enables the bottom plate 7 to stably slide and drive the mold, thereby ensuring the processing stability.

[0029] In order to install the guide rail 5, the two ends of the guide rail 5 are provided with mounting seats 8, and the opposite surfaces of the mounting seats 8 are provided with silica gel blocks 81. The guide rail 5 is fixedly installed between the two mounting seats 8, and the inner side surfaces of the mounting seats 8 are also provided with silica gel blocks 81. When the bottom plate 7 is pushed or pulled, the silica gel blocks 81 can buffer the sliding inertia of the sliding blocks 6.

[0030] As shown in Figure 5 , in order to limit and fix the bottom plate 7, the middle parts of the two guide rails 5 are also provided with locking grooves 9, and the locking grooves 9 are arranged in parallel with the guide rails 5. The two ends of the bottom plate 7 are provided with locking pieces 10 for fixing the bottom plate 7 on the locking grooves 9.
