[0002] Dentures are what people often call "false teeth". In medicine, they are a general term for restorations made after partial or complete tooth loss in the upper and lower teeth. The denture processing industry is a high-precision industry. The existing denture processing method uses resin casting as the main production process. In the actual production process, it is necessary to use a laser beam to irradiate the resin to solidify and form the denture, so the position of the laser needs to be constantly adjusted. The existing laser installation method is to lock it on the shell or fixed bracket with screws or other fixing methods, and there are also screws that are installed on the shell, but these installation methods require manual adjustment of the laser position, and there is no device that automatically adjusts the laser.

[0003] As in the prior art, a Chinese patent with publication number CN210100720U discloses a light machine horizontal rapid debugging structure, including an light machine (laser), which is fixedly mounted on an light machine fixing plate by fixing screws, and each of the four corners of the light machine fixing plate is provided with a positioning support hole, and a support spring is provided below each of the positioning support holes of the light machine fixing plate, and an adjusting nut is installed through the support spring and the positioning support hole, and the bottom end of the support spring is fixedly connected with a positioning plate, and the positioning plate is fixedly mounted on the top of the fixing bracket, and a groove and an installation groove are provided on the light machine fixing plate, and the groove and the installation groove are used in conjunction with the light machine.

[0004] Although this patent can calculate the adjustment step according to the pitch of the screws, the size of the optical machine fixing plate, the distance of the positioning hole relative to the center of the optical machine and the height of the optical machine lens, thereby adjusting the position of the optical machine, this patent still requires manual adjustment, and the adjustment process is cumbersome and troublesome. At the same time, it is very easy to cause printing errors, which is not convenient for promotion and use. Summary of the invention

The solenoid valves are all connected to the control system, and the vane pump 212 is connected to the hydraulic oil tank through another hose for conveying hydraulic oil.

[0041] The working principle of the present invention is as follows: the shell 101 is the shell of the printer, and the shell 101 is divided into two layers, the upper layer is the resin molding part of the 3D printer, and the lower layer is the part for installing the laser and the supporting seat. The lower layer is provided with an intermediate plate 102, and the intermediate plate 102 is provided with an intermediate hole 103, and the intermediate hole 103 is used to allow the laser to pass through the intermediate plate 102.

[0042] The support seat 227 is used to place the laser. When the position of the laser needs to be adjusted, the command is transmitted to the motor 201 through the control system, and the motor 201 is started to rotate forward. After the motor 201 is started, it will drive the main shaft 202 to rotate. When the main shaft 202 rotates, it drives the inner ring 232 to rotate. When the inner ring 232 rotates, it drives the circular shaft 234 to rotate. When the inner ring 232 rotates, the control block 235 receives a signal through the control system, and loosens and fixes the sliding bar 236. The sliding bar 236 slides under the action of centrifugal force and is stuck in the groove set in the middle ring 230 to drive the middle ring 230 to rotate. When the middle ring 230 rotates, it drives the first pulley 214 to rotate. The first pulley 214 drives the second pulley 216 to rotate through the transmission belt 215. When the second pulley 216 rotates, it drives the screw rod 217 to rotate. At this time, the crank 218 In threaded cooperation with the screw rod 217, the crank 218 is first moved toward the direction of the first sleeve shaft 204, and finally the spline sleeve 206 is clamped on the first sleeve shaft 204, and the first sleeve shaft 204 is driven to rotate. When the first sleeve shaft 204 rotates, the first gear 203 is driven to rotate, and the first gear 203 forms a gear rack cooperation with the second rack 223, driving the second rack 223 to move, thereby adjusting the position of the movable seat 221 on the U-shaped plate 219 in the width direction, and finally calibrating the position of the support seat 227 on the U-shaped plate 219 in the width direction. When the position of the support seat 227 changes, the position of the laser also changes accordingly. At this time, the motor 201 rotates forward, and the second rack 223 moves in the direction close to the first sleeve shaft 204. When the motor 201 reverses, the second rack 223 will move in the direction away from the first sleeve shaft 204.

[0043] The following will describe the working state of the motor 201 when it is reversed. When the motor 201 is reversed, the first pulley 214 drives the second pulley 216 to rotate through the transmission belt 215, and the screw rod 217 drives the crank 218 to slide, thereby moving the crank 218 in the direction close to the second sleeve shaft 207, and finally the spline sleeve 206 is stuck in the second sleeve shaft 207. When the second sleeve shaft 207 rotates, it will drive the first bevel gear 208 to rotate. The first bevel gear 208 and the second bevel gear 209 form a gear match and drive the transmission shaft 210 to rotate. The transmission shaft 210 drives the second gear 211 to rotate, and then drives the first rack 220 to slide on the U-shaped plate 219. When the first rack 220 slides, it drives the moving seat 221 to move through the long rod 222, thereby adjusting the position of the support seat 227 in the length direction on the U-shaped plate 219 left and right.

[0044] When it is necessary to adjust the height of the support seat 227, the speed of the motor 201 will be reset. At this time, the speed of the motor 201 will be increased, and the motor 201 will be started to rotate forward. At this time, the sliding bar 236 will slide to the outer ring 231 under the action of centrifugal force, and be stuck in the slot set in the outer ring 231, thereby driving the outer ring 231 to rotate. When the outer ring 231 rotates, it drives the fan blades 229 to rotate. When the fan blades 229 rotate, the vane pump 212 is connected to the middle hydraulic valve 224 through a hose, and is connected to the side hydraulic rod 228 through another hose. A solenoid valve is set on each hose. The solenoid valve is used to control the on and off of the hose. When the fan blade 229 rotates, the control system transmits a signal to the solenoid valve, and at the same time starts the solenoid valve on the hose connecting the vane pump 212 and the middle hydraulic valve 224, and the solenoid valve on the hose connecting the vane pump 212 and the side hydraulic rod 228 Solenoid valve, after the solenoid valve is opened, the hydraulic oil in the hydraulic oil tank is pressed into the middle hydraulic valve 224 and the side hydraulic rod 228 through the hose, thereby driving the support seat 227 to rise, thereby achieving the purpose of adjusting the height of the laser. When the support seat 227 needs to be lowered, the motor 201 is started to reverse, the fan blades 229 will draw away the hydraulic oil, and the middle hydraulic valve 224 will bring the support seat 227 down. When the angle of the support seat 227 needs to be adjusted, the control system selects to control one of the solenoid valves on the two side hydraulic rods 228, and presses the hydraulic oil into the side hydraulic rod 228 with the corresponding solenoid valve opened, thereby adjusting the side hydraulic rod 228 to rise, thereby adjusting the inclination angle of the support seat 227. When adjusting the angle of the support seat 227, the motor 201 must also be used in conjunction with forward and reverse rotation. When the motor 201 stops rotating, the sliding bar 236 is reset under the action of the small spring 233.
