Description

Technical Field

[0001] The invention belongs to the technical field of denture processing machine tools, and in particular relates to a denture trimming and drilling integrated machine. Background Art

[0002] In denture processing, drilling and trimming are crucial. Drilling is used to accurately open holes on the denture base or restoration to install connecting parts or prepare for subsequent processes. Trimming is to remove excess material after denture processing to make the denture edge smooth, the size precise, and fit the patient's mouth.

[0003] At present, small processing machine tools are commonly used in denture processing. The machine tools usually perform drilling processing on the dentures. After drilling, the dentures are trimmed by special trimming equipment. However, since drilling and trimming need to be performed separately, the efficiency becomes low. In order to improve the efficiency, some machine tools will integrate the drilling and trimming functions, such as a denture trimming and drilling integrated machine disclosed in patent announcement number CN208034090U;

[0004] However, like the denture processing device disclosed in the above-mentioned patent, even if the processing device integrates the two functions of drilling and trimming, drilling and trimming still work in sequence, that is, trimming cannot be performed simultaneously during the drilling process, and the overall efficiency is still low. Secondly, since most dentures are usually tailor-made according to different patients, when trimming the denture, the trimming grinding head can only be controlled to move along the edge of the denture for trimming. The grinding contact area is small, the trimming efficiency is low, and the use effect is not good. Summary of the invention

There are two air outlet holes 146, and a normally open solenoid valve 147 is fixedly installed inside the air outlet hole 146. The hollow block 145 is connected to the air outlet end of the air pump 131. The controller 2 controls the corresponding normally open solenoid valve 147 to work according to the electrical signal output by the second pressure detector 142. An air pressure switch 148 is fixedly installed inside the hollow block 145, and the air pressure switch 148 is electrically connected to the controller 2. Under the action of high air pressure, the moving contact of the air pressure switch 148 will gradually move back until it is closed, and when the air pressure returns to normal pressure, its moving contact will rebound and reset. This is an existing mature technology, so it will not be elaborated here.

[0040] The operating principle of the present invention is now described as follows: the denture to be processed is placed at the center of the denture placement table 4, and then the controller 2 is started;

[0041] After the controller 2 is started, it controls each electromagnetic block 129 to work, each electromagnetic block 129 is energized to generate magnetic force, and controls the current passed into each electromagnetic block 129 to gradually increase (for example, the current passed into the electromagnetic block 129 is gradually increased by sliding the variable resistance module). Under the effect of like-sex repulsion, the electromagnetic block 129 will push the connecting block 124 to move through the same-side permanent magnet 128, the magnetic isolation frame 127 and the movable block 122, and the connecting block 124 can drive the same-side adjustment roller 125 The adjusting roller 125 moves, and the movable adjusting roller 125 pushes and pulls the transmission belt 94 on the same side, so that the polishing cotton strip 11 on the outer wall of the transmission belt 94 contacts the side wall of the denture. When the polishing cotton strip 11 contacts the side wall of the denture, the displacement of each adjusting roller 125 is blocked by the denture. At this time, the connecting block 124 cannot move further, and the magnetic thrust of the electromagnetic block 129 on the permanent magnet 128 gradually increases. Therefore, the pressure between the movable block 122 and the connecting block 124 will gradually increase until the first After a pressure detector 123 detects that the trimming pressure reaches a set value (the trimming pressure can be pre-set through the controller 2 according to different dentures), the first pressure detector 123 will output an electrical signal to the controller 2. At this time, the controller 2 will control the current passing into the electromagnetic block 129 to remain constant. After the controller 2 receives the electrical signals output by each first pressure detector 123, the controller 2 will send a prompt voice through its own voice module. After receiving the prompt voice, the personnel control the horizontal drive assembly 51 through the controller 2 to adjust the position of the side plate 52 in the horizontal front-to-back direction, and then adjust the position of the mounting frame 54 in the horizontal left-to-right direction by horizontally pushing the electric push rod 53, so that the drill rod assembly 56 is directly above the denture that needs to be drilled (a laser head can be installed at the drill rod assembly 56, and the drilling point can be irradiated by the laser emitted by the laser head to ensure the accuracy of the drilling position). After the adjustment is completed, start the drilling start button on the controller 2;

[0042] At this time, the controller 2 will control the vertical push electric push rod 55 to work, and the vertical push electric push rod 55 will drive the drill rod assembly 56 and the clamping plate 63 to move downward. When the clamping plate 63 contacts the top of the denture, the clamping plate 63 is blocked and cannot move further. At this time, the telescopic end of the elastic telescopic rod 62 will retract, and the elastic squeezing force provided by the elastic telescopic rod 62 to the clamping plate 63 is used to make the clamping plate 63 stably pressed against the top of the denture, so that the denture can be pressed and fixed. At this time, the drill rod assembly 56 and the mounting plate 61 continue to move downward. The drill rod of the drill rod assembly 56 will pass through the circular hole 64, and after the travel switch 65 on the mounting plate 61 detects the position of the clamping plate 63 (the travel switch 65 determines the position of the clamping plate 63 by emitting light and calculating the reflected light), the travel switch 65 will output an electrical signal to the controller 2, and the controller 2 will start the drill rod assembly 56, and the drill rod assembly 56 can drive its own drill rod to work. The rotating drill rod can drill holes in the denture under the action of the vertical electric push rod 55 pushing down.

[0043] After the controller 2 receives the electrical signal from the travel switch 65, it will also start the drive motor 101 synchronously. The drive motor 101 drives the support roller 93 on the same side to rotate. Under the action of the transmission belt 94 on the same side, the support rollers 93 on the same side rotate synchronously, and in the transmission assembly of the chain transmission assembly 102, the support rollers 93 on the other side also rotate synchronously. At this time, the transmission belts 94 on both sides rotate synchronously, thereby driving the polishing cotton strips 11 on both sides to rotate synchronously. The polishing cotton strips 11 can trim the side walls of the denture, so that the denture can be trimmed synchronously during the drilling process, thereby improving the processing efficiency of the denture;

[0044] When the controller 2 starts the driving motor 101, it will also control the air pump 131 to work synchronously. The suction end of the air pump 131 can suck away the air inside the processing chamber 3, and the external airflow will be supplemented into the processing chamber 3 through the L-shaped opening, so that under the action of the flowing airflow, the waste chips generated during drilling and trimming can be collected at the filter 132, and the waste chips are intercepted by the filter 132 and will not be discharged with the airflow. The airflow output by the air pump 131 will enter the hollow block 145 and be discharged through the air outlet 146. When polishing When the cotton strip 11 has sufficient grinding roughness, the polishing cotton strip 11 will apply friction to the friction block 144 on the same side during its circulation, so that the friction block 144 applies pressure to the second pressure detector 142 on the same side. The second pressure detector 142 detects that the pressure is too high. At this time, the second pressure detector 142 will output a qualified electrical signal to the controller 2. As the polishing cotton strip 11 is worn, its surface gradually becomes smooth. At this time, the friction force of the polishing cotton strip 11 on the friction block 144 gradually decreases. Therefore, the pressure applied by the friction block 144 to the second pressure detector 142 on the same side gradually decreases. When the second pressure detector 142 detects that the pressure is lower than a preset value (the preset value can be pre-set by the controller 2 according to the material of the polishing cotton), the qualified electrical signal output by the second pressure detector 142 to the controller 2 disappears. At this time, the controller 2 will control the corresponding normally open solenoid valve 147 to be energized and closed, and the air pump 131 works normally and outputs the air to the inside of the hollow block 145, which will be discharged through the two air outlets 146. When one of the outlets is When the normally open solenoid valve 147 inside the air hole 146 is closed, or the normally closed solenoid valves inside the two air outlet holes 146 are closed, the air delivered to the inside of the hollow block 145 by the air pump 131 cannot be discharged in time due to the smaller exhaust aperture of the hollow block 145. At this time, the air pressure inside the hollow block 145 will gradually increase, so that the moving contact of the air pressure switch 148 is back-pressed and closed. After the controller 2 receives the closing electrical signal of the air pressure switch 148, the controller 2 will remind the personnel to replace the polishing cotton strip 11 through its own voice module;

[0045] After the drill rod assembly 56 and the drive motor 101 have been working for a certain period of time (the timed working time is pre-set by the controller 2 according to different denture processing requirements), the controller 2 controls the drill rod assembly 56 and the drive motor 101 to stop working, and then controls each electromagnetic block 129 to cut off the power, and controls the vertical push electric push rod 55 to drive the drill rod assembly 56 and the clamping plate 63 and other components to move back and reset. At this point, the drilling and trimming work of the denture is completed.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
