The two ends of the motion platform 3.8 are respectively provided with an air cylinder 3.12, the air pump is arranged on a bottom plate of the main frame 1 and is connected with the air cylinder 3.12 through an air pipe 3.11, the two clamps are hoisted under the motion platform 3.8 through corresponding clamp connecting arms, the clamp connecting arms 3.13 are connected with air cylinder sliding blocks (air cylinder pistons), the motion platform 3.8 is provided with a track along the length direction, and the air cylinder sliding blocks are connected with the track in a sliding manner. Gas is sent into the cylinder 3.12 through the trachea 3.11, and the anchor clamps pass through anchor clamps linking arm 3.13 and are connected with the cylinder slider, make the cylinder 3.12 can drive anchor clamps and open and shut.

Referring to fig. 8, the jig includes: a plurality of clamping columns 3.17, springs 3.16, limit plates 3.15 and a rear shell 3.14. The lower end of each clamping column 3.17 penetrates through a spring 3.16, and the spring 3.16 enables the clamping column 3.17 to return to the initial position in a natural state; the limiting plate 3.15 is fixed at the shell opening of the rear shell 3.14, the tail part of each clamping column 3.17 penetrates through a limiting hole of the limiting plate 3.15, the front ends of the clamps are tightly arranged into a honeycomb shape to form a clamping part, the clamping part of the clamps is a vertical plane in a natural state, and when the two clamps clamp parts, the clamping columns at the stressed parts compress the springs to form depressions according to the shapes of the parts to clamp the parts.

The specific working process of the automatic taking and wax infiltration post-treatment device for the nonmetal laser sintered part comprises the following steps:

after the non-metal parts are printed, the non-metal parts are placed on the wax paper 2, the control system controls the motor of the automatic part taking mechanism to work, the moving platform 3.8 moves along the guide rail through the guide rail sliding block 3.7 by the rotation of the lead screw, and when the clamp moves to the position of the part, the clamp stops. Then the air pump starts to work, the generated air is communicated to the air cylinder 3.12 through the air pipe 3.11 to push the piston to move, when the piston moves, the clamp connecting arm 3.13 connected to the piston drives the clamp to move towards the center, after the end part of the clamping column 3.17 touches a part, the compression spring 3.16 is moved backwards, a recess is formed at the part which is touched, and the part is clamped through the elastic force of the spring 3.16 and the support force generated at the recess. Then the automatic motor of getting works again, and control motion platform 3.8 removes, transports the part to oozing wax platform 4.1 top, and cylinder 3.12 is reverse to be put through, and the piston is to both sides removal control anchor clamps and loosen, and the part steadily falls into oozing on the wax net 4.2. The angle adjusting mechanism motor of the wax infiltration device works, the lead screw rotates to enable the angle adjusting supporting rod 4.9 to move upwards, the supporting rod connecting seat and the wax infiltration platform 4.1 rotate relatively, the right-angle fastener 4.11 and the pull rod 4.8 rotate relatively, and the wax infiltration platform 4.1 and parts arranged on the platform generate a certain inclination angle. At the moment, the wax liquid in the wax infiltration cylinder is heated and kept at 70 ℃ by the heating module of the wax infiltration cylinder 5, the motor of the lifting mechanism of the wax infiltration device works, and the lead screw rotates to drive the lifting column 4.14 and the optical axis sliding block 4.12 to slowly move downwards along the optical axis, so that the wax infiltration platform 4.1 and the parts are slowly immersed in the wax liquid in the wax infiltration cylinder 5. After the wax infiltration is finished, the motor of the lifting mechanism rotates reversely to enable the wax infiltration platform 4.1 to move upwards and move out of the liquid level of the wax infiltration cylinder 5, and meanwhile, the motor of the angle adjusting mechanism works to adjust the inclined wax infiltration platform 4.1 to be horizontal. When the wax infiltration platform 4.1 is level with the upper surface of the wax infiltration cylinder 5, the lifting motor 4.16 stops working. Standing for a moment, after the redundant wax liquid drops return to the wax infiltration cylinder 5, the pneumatic system works, the cylinder 3.12 drives the clamp to clamp the part after wax infiltration is completed, then the motor of the movement mechanism works to move the clamp and the clamped part to the central position of the wax absorption paper 2. Then the cylinder 3.12 moves reversely, the clamp opens, the part falls into the center of the wax-absorbing paper 2, and the constant temperature of 35 ℃ is kept above the wax-permeating device platform. And after the wax absorbing paper 2 absorbs the redundant wax liquid, taking out the part.

The invention not only improves the working efficiency, the wax infiltration effect and the automation level of the wax infiltration treatment, but also reduces the working intensity of people, thereby reducing various defects caused by manual workpiece taking and wax infiltration.
