It uses software and numerical control systems to stack special metal materials, non-metallic materials and medical biomaterials layer by layer through extrusion, sintering, melting, photocuring, spraying, etc. to produce physical objects. The existing surface repair equipment has difficulty in fixing the additive products due to the complex structure of the additive products to be processed and the different heights of the additive products, which causes loosening during the surface repair process, resulting in instability of the additive products and errors in the surface repair, which requires secondary rework and poor repair results.

A fixed column is arranged inside a housing, and a telescopic tube, a telescopic column, a baffle plate, a fixed plate and a spring are installed at the bottom of the fixed column. The fixed column and the telescopic tube, the telescopic column, the baffle plate, the fixed plate and the spring are driven downward by a rotating handle. When in contact with the additive product, the spring is squeezed by the telescopic columns on the sides of the fixed plates on both sides, and the fixed plate clamps the two sides of the additive product by the compressed state of the spring. Different additive products can be adapted, the stability of the additive product is improved, and looseness during the repair process is avoided. However, the patent still has the following problems in actual use: Although the surface treatment and repair equipment for additive manufacturing products is equipped with a fixed column inside the shell, and a telescopic tube, a telescopic column, a baffle plate, a fixed plate and a spring are installed at the bottom of the fixed column so that the fixed plate can clamp the two sides of the additive product, it can only fix regular additive products and cannot adapt to some special-shaped additive products, thus affecting the fixation of the special-shaped products. At the same time, the additive products cannot be sandblasted before spraying, thus affecting the spraying effect of the additive products. The angle between the spray head and the workpiece surface cannot be adjusted, resulting in uneven spraying of paint mist, affecting the quality of spraying.

By utilizing the characteristic of the engagement connection between the mounting pin 232 and the repair nozzle 233, the installation and disassembly of the repair nozzle 233 can be achieved, and different types of repair nozzles 233 can be replaced as needed.

[0033] Working principle: Before using this kind of support-stabilized additive manufacturing product surface treatment and repair equipment, it is necessary to first check the overall condition of the device to ensure that it can work normally. Figure 1 - Fig.11As shown, first, the lifting motor 104 is used to drive the sprocket transmission assembly 105 and the lifting threaded rod 106 to rotate, so that the lifting threaded sleeve 107 drives the adjustment support plate 142 to move up and down, so as to adjust the height of the workpiece. At the same time, the adjusting knob 110 is turned to drive the adjustment threaded rod 111 to rotate, so that the adjustment threaded bracket 112 drives the adjustment sliding rod 113 and the adjustment sliding plate 114 to move, so as to adjust the distance between the two adjustment sliding plates 114, so as to facilitate clamping of workpieces of different sizes. The clamping rotating groove 118 and the clamping rotating shaft 119 can realize the relative rotation of the clamping rotating rod 120. When the inner diameter of the workpiece is larger than the spacing between the clamping rotating supports 117, the clamping rotating rod 120 can be rotated outward, and the fastening threaded rod 122 can be driven to rotate by rotating the fastening knob 121, so that the fastening threaded sleeve 123 drives the fastening plate 124 to move, and under the elastic force of the fastening spring 127, the fastening sliding rod 125 drives the fastening pressure block 126 to slide inside the fastening plate 124, thereby fixing the workpiece.

[0034] Secondly, when the inner diameter of the workpiece is smaller than the spacing between the clamping rotating supports 117, the clamping rotating rod 120 can be rotated inwardly, and the outer side of the workpiece can be clamped by tightening the pressure block 126. When the outer surface of the workpiece is flat, the entire clamping rotating rod 120 is rotated to a vertical state, so that the flat workpiece can be clamped and fixed, thereby adapting to special-shaped parts of different shapes. Through the characteristics of the sliding connection between the supporting sliding rod 129 and the supporting sliding sleeve 130 inside the supporting sliding bracket 128, the horizontal position of the first lifting cylinder 132 of the first supporting sliding plate 131 industry can be adjusted, and the first lifting cylinder 132 of the first supporting sliding plate 131 industry can be adjusted. The second supporting sliding plate 135 moves to the center position of the workpiece, and the first lifting cylinder 132 is started to adjust the height of the supporting chassis 133, and the first electric telescopic rod 134 is used to adjust the distance between the supporting chassis 133 and the second supporting sliding plate 135. The supporting rotating rod 139 can realize the limiting sliding sleeve 137 to drive the supporting bracket 140 and the two-way clamping plate 141 to move relative to each other. Through the structural characteristics of the two-way clamping plate 141, not only the bottom of the workpiece can be supported, but also the workpiece with a hollow interior can be supported from the inside of the workpiece, thereby improving the stability of the workpiece spraying.

[0035] Finally, the mixing motor 203 is used to drive the first mixing auger 204 and the second mixing auger 205 to rotate, and the mixing bracket 206 is used to drive the cleaning spiral blade 207 to rotate, so as to stir the raw materials inside the first mixing box 201 and the second mixing box 202 to improve the mixing uniformity of the raw materials. The first mixing box 201 can be filled with raw materials for sandblasting, and the second mixing box 202 can be filled with raw materials for spraying, so as to facilitate the sandblasting and spraying of the workpiece. The material is put into the conveying pipe 208 through the feeding hopper 209, and the conveying motor 210 is started to drive the conveying auger 211 to rotate. Under the action of the valve spring 213, the valve piston 214 is opened, and the raw materials are injected into the first mixing box 201 and the second mixing box 202, so as to facilitate the mixing of the raw materials. The raw materials are fed into the repair machine through the connecting pipe 218 and the serpentine pipe 219 through the discharge pump 217. In the compound nozzle 233, sandblasting and spraying of the workpiece are carried out. By starting the translation motor 221 to drive the translation threaded rod 222 to rotate, the translation threaded sleeve 223 drives the second electric telescopic rod 224 and the nozzle mounting seat 225 to move, so that uniform sandblasting and spraying of the workpiece can be achieved. By using the characteristics of the rotational connection between the damping rotation sleeve 226 and the universal ball 227, the angle of the repair nozzle 233 can be adjusted so that the repair nozzle 233 and the surface of the workpiece are in a vertical state, thereby improving the effect of sandblasting and spraying. By rotating the mounting turntable 229 and under the limiting action of the spiral slide groove 230, the limiting slider 231 can drive the mounting pin 232 to slide inside the mounting bracket 228. By utilizing the characteristics of the locking connection between the mounting pin 232 and the repair nozzle 233, the installation and disassembly of the repair nozzle 233 can be achieved, and different types of repair nozzles 233 can be replaced as needed.
