Description

Technical Field

[0001] This invention belongs to the field of dental prosthesis processing machine tool technology, and in particular relates to a dental prosthesis trimming and drilling integrated machine. Background Technology

[0002] In denture fabrication, drilling and trimming are crucial. Drilling is used to precisely create holes in the denture base or restoration to install connecting components or prepare for subsequent processes. Trimming removes excess material after denture fabrication, making the denture edges smooth, dimensionally accurate, and fit the patient's mouth perfectly.

[0003] Currently, small processing machine tools are commonly used equipment in denture processing. The machine tools are usually used to drill holes in dentures. After drilling, the dentures are trimmed using specialized trimming equipment. However, since drilling and trimming need to be done separately, the efficiency is low. In order to improve efficiency, some machine tools will integrate drilling and trimming functions, such as a denture trimming and drilling integrated machine disclosed in patent publication number CN208034090U.

[0004] However, like the denture processing device disclosed in the aforementioned patent, even though the processing device integrates both drilling and trimming functions, drilling and trimming still work sequentially. That is, trimming cannot be performed simultaneously during drilling, resulting in low overall efficiency. Secondly, since most dentures are usually custom-made for different patients, when trimming dentures, the trimming 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 effect is not good. Summary of the Invention

[0034] The drilling unit 5 is equipped with a clamping mechanism 6, which is used to fix the denture.

The end face of the clamping plate 63 has a circular hole 64 that is coaxial with the drill rod assembly 56. A limit switch 65 is fixedly installed on one side of the bottom of the mounting plate 61. The controller 2 controls the drive mechanism 10 to work according to the electrical signal output by the limit switch 65. The clamping plate 63 and the two elastic telescopic rods 62 are fixed with locking parts such as nuts. The appropriate size clamping plate 63 can be replaced according to different dentures.

[0035] Two fixed covers 7 are symmetrically arranged on the two side walls of the processing table 1. The two cavity walls of the processing cavity 3 have through holes 8 that communicate with the fixed covers 7. Belt support assemblies 9 are installed on the inner walls of both fixed covers 7. Each belt support assembly 9 includes two support plates 91 fixedly installed on the inner wall of the fixed cover 7, and a connecting plate 92 is fixedly provided between the two support plates 91. A set of support rollers 93 is rotatably connected to the end faces of the two support plates 91. The two support rollers 93 are connected to a drive belt 94 for transmission. The polishing cotton strip 11 is detachable from the drive belt 94. The connecting plate 92 is disassembled and a baffle 95 is fixedly installed on its end face. A follower plate 96 is provided on one side of the baffle 95. Two adjusting wheels 97 are fixedly installed on the side wall of the follower plate 96 away from the baffle 95.

The circular rod is installed on the side wall of the baffle 95 and is slidably connected to the side wall of the follower plate 96. The elastic element is located between the baffle 95 and the follower plate 96.

[0036] The processing table 1 is equipped with a drive mechanism 10, which is used to drive two belt support assemblies 9. The outer walls of the two belt support assemblies 9 are fitted with detachable polishing cotton strips 11. The drive mechanism 10 includes a drive motor 101 fixedly installed on the end face of the processing table 1.

The drive motor 101 is electrically connected to the controller 2. The chain drive assembly 102 includes components such as a drive chain and sprockets.

[0037] The extrusion adjustment unit 12 is installed inside the processing chamber 3 and is used to adjust the belt support assembly 9. Both extrusion adjustment units 12 include multiple slotted holes 121 on the end face of the processing table 1. Each slotted hole 121 has a movable block 122 slidably connected inside it. A first pressure detector 123 is fixedly inserted into the end face of the movable block 122, and a connecting block 124 is installed on the pressure measuring end of the first pressure detector 123. An adjusting roller 125 is rotatably connected to the bottom of the connecting block 124, and the adjusting roller 125 is connected to the transmission belt 94.

A magnetic shielding frame 127 is installed at the end of the movable block 122 away from the connecting block 124, and a permanent magnet 128 is fixedly embedded at the end of the magnetic shielding frame 127 away from the movable block 122. An electromagnetic block 129 is fixedly installed on the side wall of the strip hole 121 away from the support spring 126. The first pressure detector 123 and the electromagnetic block 129 are both electrically connected to the controller 2. After the electromagnetic block 129 is energized and generates magnetic force, the permanent magnet 128 will be subjected to magnetic repulsion under the action of like poles repulsion.

[0038] The dust collection unit 13 is installed on the end face of the processing table 1 and is used to absorb the waste generated during drilling and trimming. The dust collection unit 13 includes an air pump 131 fixedly installed on the side wall of the processing table 1, and the suction end of the air pump 131 is connected to the interior of the processing table 1. A filter screen 132 is installed inside the processing chamber 3 near the suction end of the air pump 131. The air pump 131 is electrically connected to the controller 2. An opening is left on the side wall of the processing chamber 3, and a sealing cover is provided at the opening for periodically transferring the waste intercepted by the filter screen 132 out for processing.

[0039] The replacement indicator unit 14 is installed inside the processing table 1 and is connected to the air outlet of the dust collection unit 13. The replacement indicator unit 14 includes support slots 141 fixedly installed on the two inner walls of the processing cavity 3. A second pressure detector 142 is installed inside each of the two support slots 141. A fixing block 143 is installed at the pressure measuring end of the second pressure detector 142. A friction block 144 is fixedly installed at the end of the fixing block 143. The side wall of the friction block 144 is in contact with the outer side wall of the polishing cotton strip 11 on the same side. A hollow block 145 is fixedly installed on the end face of the processing table 1. The side wall of the hollow block 145 is open. Two air outlets 146 are provided, and normally open solenoid valves 147 are fixedly installed inside the air outlets 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. A pressure switch 148 is fixedly installed inside the hollow block 145 and is electrically connected to the controller 2. Under the action of high air pressure, the moving contact of the pressure switch 148 will gradually move back until it closes. When the air pressure returns to normal pressure, its moving contact will spring back to reset. This is a mature existing technology, so it will not be described in detail here.

[0040] The operating principle of the present invention is explained 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 the operation of each electromagnetic block 129. Each electromagnetic block 129 generates magnetic force when energized, and the current flowing through each electromagnetic block 129 is gradually increased (for example, by gradually increasing the current flowing through the electromagnetic block 129 through a sliding rheostat module). Under the action of like poles repelling each other, the electromagnetic blocks 129 will push the connecting block 124 to move through the permanent magnet 128, the magnetic shielding frame 127 and the movable block 122 on the same side. The connecting block 124 can then drive the adjusting roller 125 on the same side. The movement of the adjusting roller 125 pushes and pulls the transmission belt 94 on the same side, causing the polishing cotton strip 11 on the outer wall of the transmission belt 94 to contact the side wall of the denture. Once 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 point, 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 gradually increases until the... After a pressure detector 123 detects that the trimming pressure has reached the set value (this trimming pressure can be preset by 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 flowing into the electromagnetic block 129 to remain constant. After the controller 2 receives the electrical signals output by each of the first pressure detectors 123, the controller 2 will issue a prompt voice through its own voice module. After receiving the prompt voice, the personnel will control the horizontal drive component 51 to work through the controller 2, thereby adjusting the position of the side plate 52 in the horizontal front-back direction. Then, the personnel will adjust the position of the mounting bracket 54 in the horizontal left-right direction by pushing the electric push rod 53, so that the drill rod component 56 is directly above the denture that needs to be drilled (a laser head can be installed at the drill rod component 56, and the drilling position can be ensured by the laser emitted by the laser head irradiating the drilling point). After the adjustment is completed, the drilling start button on the controller 2 will be activated.

[0042] At this time, controller 2 will control the vertical push electric actuator 55 to work, which 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, it will be blocked and unable to move further. At this time, the telescopic end of the elastic telescopic rod 62 will retract, and the elastic pressure provided by the elastic telescopic rod 62 on the clamping plate 63 will make the clamping plate 63 stably press against the top of the denture, thereby clamping and fixing the denture. Meanwhile, the drill rod assembly 56 and the mounting plate 61 continue to move downward. As the drill rod of the drill rod assembly 56 moves, the drill rod will pass through the round hole 64. After the limit switch 65 on the mounting plate 61 detects the position of the clamping plate 63 (the limit switch 65 determines the position of the clamping plate 63 by emitting light and calculating the received reflected light), the limit switch 65 will output an electrical signal to the controller 2. At this time, the controller 2 will start the drill rod assembly 56 to work. 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 push electric push rod 55.

[0043] After receiving the electrical signal from the limit switch 65, the controller 2 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, each support roller 93 on the same side rotates synchronously. In the transmission component of the chain transmission assembly 102, each support roller 93 on the other side will also rotate synchronously. At this time, the transmission belts 94 on both sides rotate synchronously, which can drive the polishing cotton strips 11 on both sides to rotate synchronously. The polishing cotton strips 11 can trim the sidewalls of the denture, so that the denture can be trimmed synchronously during the drilling process, improving the processing efficiency of the denture.

[0044] When controller 2 starts drive motor 101, it also controls air pump 131 to work synchronously. The suction end of air pump 131 can suck away the air inside processing chamber 3, while external airflow will supplement the processing chamber 3 through L-shaped opening. Thus, under the action of the flowing airflow, the waste generated during drilling and trimming can be collected at filter screen 132, and the waste is intercepted by filter screen 132 and will not be discharged with the airflow. The airflow output by air pump 131 will enter hollow block 145 and be discharged through air outlet 146. When polishing... When the polishing cotton strip 11 has sufficient abrasive roughness, during its cyclic rotation, the polishing cotton strip 11 applies frictional force to the friction block 144 on the same side, thereby causing the friction block 144 to apply pressure to the second pressure detector 142 on the same side. If the second pressure detector 142 detects excessive pressure, it will output a qualified electrical signal to the controller 2. As the polishing cotton strip 11 wears down and its surface gradually becomes smoother, the frictional force between the polishing cotton strip 11 and 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 pressure below a preset value (this preset value can be preset according to the material of the polishing cotton via the controller 2), 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 energize and close. The air pump 131, which normally outputs air to the hollow block 145, will be discharged through the two air outlets 146. When one of the outlets... When the normally open solenoid valve 147 inside the air outlet 146 is closed, or when the normally closed solenoid valves inside both air outlets 146 are closed, the air pump 131 delivers air into the hollow block 145 to the interior of the hollow block 145 cannot be discharged in time because the exhaust port diameter of the hollow block 145 becomes smaller. At this time, the air pressure inside the hollow block 145 will gradually increase, which will cause the moving contact of the pressure switch 148 to be pressed back and closed. After receiving the closing electrical signal of the 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 timer is preset 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. Then, it controls the power off of each electromagnetic block 129 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 to their original positions. 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 principles of the present invention should be included within the protection scope of the present invention.
