However, in the actual application of this application, this is not limiting.

[0048] Example 1: Please refer to Figure 1-4 、 Figure 10-11 As shown, this embodiment provides a denture engraving machine 100, which includes a main body 110 with a processing chamber 121, a grinding disc 116 installed in the processing chamber 121, an air guide sleeve 123 installed on the main body 110, and a diaphragm air pump 120 installed on the main body 110 and connected to the air guide sleeve 123; wherein, the end of the air guide sleeve 123 is arranged opposite to the grinding disc 116, and the end of the air guide sleeve 123 is provided with a blowing hole 16a, and an air flow is generated by the diaphragm air pump 120, and the air flow passes through the air guide sleeve 123 and blows toward the grinding disc 116 from the blowing hole 16a, so that the debris on the grinding disc 116 can be cleaned during the processing of the material or after the processing of the material is completed.

[0049] According to the above scheme, it can be understood that this embodiment provides a diaphragm air pump 120 to conduct the air guide sleeve 123, and the end of the air guide sleeve 123 is arranged opposite to the grinding disc 116 and is provided with a blowing hole 16a, so that an air flow can be generated by the diaphragm air pump 120, and then blown out from the blowing hole 16a to the grinding disc 116 after passing through the inside of the air guide sleeve 123, so that the debris on the grinding disc 116 can be blown into the bottom of the processing chamber 121, avoiding the negative impact of the debris on the subsequent grinding process, replacing manual cleaning of the grinding disc 116, and improving the processing accuracy and continuity of the denture engraving machine 100.

[0050] According to the above scheme, it can be understood that the grinding disc 116 needs to be calibrated in advance before grinding the material. Therefore, the upper part of the grinding disc 116 can be called a calibration disc, or the grinding disc 116 can be called a calibration disc. The denture engraving machine 100 also includes a calibration rod 131 that can be detachably mounted on the end of the air guide sleeve 123. The blowing hole 16a is provided on one side of the calibration rod 131. The calibration rod 131 is used to calibrate the grinding disc 116. The specific calibration process of the calibration rod 131 can refer to Example 3 and will not be repeated here.

[0051] Please refer to Figure 10-11As shown, in some embodiments, the air blowing holes 16a are set to be multiple, and the number of the multiple air blowing holes 16a can be set to two, three or four, and a suitable number can be set according to the area or position that the grinding disc 116 needs to be cleaned; preferably, in this embodiment, the concentrated air blowing holes 16a are set to two, and the angle formed by the connection axis of the two air blowing holes 16a and the center of the air guide sleeve 123 is 120°, while in other embodiments, the angle formed by the connection axis of the two air blowing holes 16a and the center of the air guide sleeve 123 can be set to other angles, and any angle between 90 and 180° can be set. Figure 12 As shown, the angles formed by the two blowing holes 16a at the end of the air guide sleeve 123 and the central connection axis of the air guide sleeve 123 are designed to be 120°, so that the two blowing holes 16a can blow air in different directions respectively and expand the blowing area, thereby not only ensuring better removal of processing debris during processing, but also blowing air to the tool holder 125 located on the side of the grinding disc 116 in the processing chamber 121, thereby also achieving the purpose of clearing debris on the tool holder 125 and expanding the cleaning range.

[0052] according to Figure 12 As shown, preferably, any two adjacent blowing holes 16a form a fixed angle 16b with the connection axis of the center of the air guide sleeve 123. It can be understood that this design allows any two adjacent blowing holes 16a to be spaced apart from each other, so that they form a fixed angle 16b with the connection axis of the center of the air guide sleeve 123, and this spacing allows the valve of the fixed angle 16b to maintain any angle between 90 and 180 degrees, avoiding any two adjacent blowing holes 16a being too close to each other, causing the angle to overlap or be zero, thereby resulting in a smaller cleaning area for blowing.

[0053] Please refer to Figure 3-4 、 Figure 10-11As shown, preferably, the denture engraving machine 100 also includes a connecting elbow 161, and the number of the connecting elbow 161 corresponds to the number of the blowing holes 16a, and the air guide sleeve 123 is connected to the diaphragm air pump 120 through the connecting elbow 161; it can be understood that the purpose of setting the connecting elbow 161 is to connect the air guide pipe of the diaphragm air pump 120 with the air guide sleeve 123, so that the communication effect of the diaphragm air pump 120 is better, and the connection stability between the diaphragm air pump 120 and the air guide sleeve 123 can be improved, and the fixation of different air guide pipes of the diaphragm air pump 120 corresponding to the multiple air guide holes can be improved, so as to avoid the situation where the fixing effect is unstable when the multiple air guide pipes of the diaphragm air pump 120 are directly connected; further, a connecting elbow 161 is provided in the air guide sleeve 123 61 corresponds to the air guide duct 16c, and the air guide duct 16c extends to the air hole 16a in the air guide sleeve 123. It can be understood that this structure can further enhance the blowing strength of the air hole 16a, and prevent the air guide sleeve 123 from directly receiving the airflow blown from the diaphragm air pump 120, thereby reducing the airflow strength blown out of the air hole 16a due to the larger internal space of the air guide sleeve 123; in addition, the present embodiment blows air through the air guide sleeve 123 through the diaphragm air pump 120, and independently forms the air guide duct 16c by passing the diaphragm air pump 120 through the space in the air guide sleeve 123, so that the air guide sleeve 123 will not be affected by the airflow, thereby promoting the stability of the calibration rod 131 installed on the air guide sleeve 123 and the subsequent grinding rod.

[0054] Please refer to Figure 10-11 As shown, preferably, the denture engraving machine 100 further includes a clamping machine 122. It can be understood that the clamping machine 122 is used to fix the air guide sleeve 123. The connecting elbow 161 is installed on one side of the clamping machine 122, and multiple connecting elbows 161 are arranged at intervals on the clamping machine 122. The air guide sleeve 123 is installed on the clamping machine 122, and the clamping machine 122 is provided with a connecting channel 16d for connecting the connecting elbow 161 and the air guide sleeve 123. It can be understood that the spaced elbows 161 are arranged at intervals. The membrane air pump 120 is connected to the connecting elbow 161 through an air guide tube, and the connecting elbow 161 is installed on the clamping machine 122, so that the diaphragm air pump 120 is connected to the clamping machine 122, and a connecting channel 16d is provided in the clamping machine 122 for connecting the connecting elbow 161 and the air guide sleeve 123, thereby further enabling the diaphragm air pump 120 to be connected to the air guide sleeve 123 through the clamping machine 122, and finally the blowing hole 16a can blow air outward.

[0055] Please refer to Figure 1-4As shown, preferably, the denture engraving machine 100 further includes an A-axis motion bracket 111, a B-axis motion bracket 112, and a C-axis motion bracket 113 installed on the main body 110, the A-axis motion bracket 111, the B-axis motion bracket 112, and the C-axis motion bracket 113 are connected to each other, and the clamping machine 122 is installed on the A-axis motion bracket 111 or the B-axis motion bracket 112 or the C-axis motion bracket 113; it can be understood that in this embodiment, the A-axis motion bracket 111 moves along the A-axis, the B-axis motion bracket 112 moves along the B-axis, and the C-axis motion bracket 113 moves along the C-axis, and this embodiment In the example, the clamping machine 122 is installed on the C-axis motion bracket 113 and can move along the C-axis with the C-axis motion bracket 113. When the A-axis motion bracket 111 and the B-axis motion bracket 112 move, the clamping machine 122 will also move along the A-axis and / or B-axis with the C-axis motion bracket 113, so that the clamping machine 122 can drive the air guide sleeve 123 to move in the processing chamber 121 during the movement, and the air guide sleeve 123 can drive the calibration rod 131 installed thereon to calibrate the calibration disk, and can also clamp the grinding knife to grind the material on the grinding disk 116.

[0056] Please refer to Figure 2-3 As shown, preferably, a processing chamber 121 is provided in the main body 110, and the denture engraving machine 100 also includes an A-axis rotating member 114 and a B-axis rotating member 115 installed in the processing chamber 121, and a grinding disc 116 is installed on the A-axis rotating member 114 or the B-axis rotating member 115 for rotation to achieve the rotation adjustment required for position calibration or the rotation adjustment required for grinding.

[0057] According to the above solution, optionally, the A axis of this embodiment is arranged along the first direction, the B axis is arranged along the second direction, and the C axis is arranged along the third direction.

[0058] Example 2: Please refer to Figure 1-4 As shown, based on Example 1, this embodiment provides a denture engraving machine 100, which includes: a main shaft 117 connected to the main body 110, a first sealing frame 126 and a second sealing frame 127; wherein, the main shaft 117 includes a clamping machine 122 and a shaft sleeve, the shaft sleeve is the air guide sleeve 123 in Example 1, for ease of understanding, this embodiment continues to use the "air guide sleeve 123", and the main shaft 117 can be extended into the processing chamber 121 through the air guide sleeve 123 for movement, the first sealing frame 126 is installed on one side of the processing chamber 121, and the second sealing frame 127 is installed on the other side of the processing chamber 121; in this embodiment, the air guide sleeve 123 can be extended into the processing chamber 121 through one of the first sealing frame 126 and the second sealing frame 127 for movement to perform calibration and grinding processing.

[0059] Please refer to Figure 2-4 、 Figure 12-13 As shown, preferably, in this embodiment, the main shaft 117 passes through the first sealing frame 126 and then extends into the processing chamber 121. The first sealing frame 126 is sealed with the main shaft 117 and the processing chamber 121, and can be elastically deformed as the main shaft 117 moves in the processing chamber 121 to maintain the sealed connection between the first sealing frame 126 and the main shaft 117. The second sealing frame 127 is movably connected to the main body 110 to seal or open the processing chamber 121 through the second sealing frame 127. It can be understood that in this embodiment, the first sealing frame 126 is in a relatively sealed state with the processing chamber 121 and the main shaft 117, which also makes the first sealing frame 126 relatively sealed. The frame 126 always maintains a sealed connection with the processing chamber 121 and the main shaft 117, and the denture engraving machine 100 needs to open the processing chamber 121 to operate the grinder and the tool holder 125 therein. Therefore, this embodiment is movably connected to the main body 110 through the second sealing frame 127, so that the processing chamber 121 can be opened or sealed through the second sealing frame 127 to achieve the sealing of the main shaft 117 extending into the processing chamber 121 through the first sealing frame 126, and at the same time, the processing chamber 121 can also be opened on the other side, which can maintain the sealing effect without affecting the operation of the processing chamber 121.

[0060] Please refer to Figure 2-3 、 Figure 12-13As shown, according to the above scheme, specifically, the processing chamber 121 is provided with a first window 14a, and the air guide sleeve 123 extends into the processing chamber 121 from the first window 14a; further, the first sealing frame 126 includes a first sealing portion 141 and a second sealing portion 142, the first sealing portion 141 is fixed to the clamping machine 122, and the second sealing portion 142 is fixed to the processing chamber 121 on the peripheral side of the first window 14a; optionally, in this embodiment, the first sealing portion 141 and the second sealing portion 142 are both configured as a smooth planar structure, which can be made of either rigid material or flexible material, and the first sealing portion 141 is fixed to the clamping machine 122 by using fixing screws. The clamping machine 122 is fixed on the side facing the processing chamber 121, and the second sealing portion 142 is fixed to the processing chamber 121 on the peripheral side of the first window 14a. In this embodiment, silicone is used as the material of the first sealing frame 126 and the second sealing frame 127, so as to maintain the tightness of the sealing of the first window 14a and the flexibility of the connection between the air guide sleeve 123, so as to meet the sealing effect during the movement of the air guide sleeve 123. Furthermore, the processing chamber 121 is provided with a first sealing groove 15a on the peripheral side of the first window 14a, and the second sealing portion 142 is embedded in the first sealing groove 15a. The second sealing portion 142 is provided through the first sealing groove 15a. 142 is engaged with the side opposite to the first sealing portion 142 to improve the sealing tightness between the second sealing portion 142 and the processing chamber 121 at the first window 14a; in addition, the first sealing frame 126 also includes an elastic sealing layer 143, and the elastic sealing layer 143 is provided in plurality. It can be understood that the elastic sealing layer 143 is a sealing pleated layer, and the elastic sealing layer 143 is provided between the first sealing portion 141 and the second sealing portion 142, so that the air guide sleeve 123 can be deformed along with the air guide sleeve 123 during the movement through the elastic sealing layer 143, that is, when the air guide sleeve 123 moves in a certain direction, the side of the air guide sleeve 123 on the opposite side of the air guide sleeve 123 is deformed. Part of the elastic sealing layer 143 will be stretched, while part of the elastic sealing layer 143 located on the opposite side of the air guide sleeve 123 will be compressed, thereby achieving the effect of maintaining the seal; further, any two adjacent elastic sealing layers 143 are separated to form a buffer layer 144, and the buffer layer 144 and the elastic sealing layer 143 are integrally formed. The purpose of providing the buffer layer 144 is to buffer the elastic sealing layer 143 during the deformation process of the air guide sleeve 123, thereby avoiding the gap between any adjacent elastic sealing layers 143 being too small, resulting in the deformation amount being unable to meet the movement requirements of the air guide sleeve 123, thereby resulting in a decrease in sealing performance.

[0061] Please refer to Figure 2-3 、 Figure 12-13As shown, preferably, the main body 110 also includes a pivot member 119, and the processing chamber 121 is provided with a second window 14b. One end of the pivot member 119 is installed on one side of the second window 14b, and the other end is connected to the second sealing frame 127. The second sealing frame 127 can pivot on the processing chamber 121 through the pivot member 119; it can be understood that when the denture engraving machine 100 needs to work (engraving and grinding dentures or materials), the second window 14b is sealed by using the second sealing frame 127, so that the processing chamber 121 is sealed, and when it is necessary to operate the material or grinder and other components in the processing chamber 121, the second sealing frame 127 can be pulled to drive the pivot member 119 to rotate so that the second sealing frame 127 is flipped upward from the second window 14b, so that the second window 14b is opened, and the user can operate the processing chamber 121 through the second window 14b.

[0062] Please refer to Figure 2-3 As shown, according to the above scheme, preferably, the pivot member 119 is set as a pneumatic pivot member. The advantage of setting the pneumatic pivot member 119 is that it can increase the friction during the rotation process, so that when the second sealing frame 127 is sealing the second window 14b, it is necessary to use a larger force to pull the second sealing frame 127 so that the second sealing frame 127 is flipped upward from the second window 14b; and when the second sealing frame 127 is in a fully open state and is located above the second window 14b, it is necessary to use a larger force to push the second sealing frame 127 so that the second sealing frame 127 seals the second window 14b, and when the second sealing frame 127 is in a state of sealing the second window 14b or the second sealing frame 127 is in a state of completely flipping upward from the second window 14b, the pneumatic pivot member can achieve the effect of maximum friction to maintain the continuity of its state.

[0063] Please refer to Figure 2As shown, specifically, the pivot member 119 includes a first pivot member 145 and a second pivot member 146 at different positions; one end of the first pivot member 145 is installed at the center of the processing chamber 121 on the second window 14b side, and the other end is connected to the bottom end of the second sealing frame 127; one end of the second pivot member 146 is installed at the top of the processing chamber 121 on the second window 14b side, and the other end is connected to the center of the second sealing frame 127; it can be understood that the purpose of setting this structure is to enable the pivot member 119 to achieve the effect of allowing the second sealing frame 127 to be flipped upward when it is flipped out of the second window 14b. The advantage of setting the flip upward is that This is to avoid the second window 14b taking up too much space, so that the denture engraving machine 100 can save more space during operation; in other embodiments, one end of the first pivot member 145 can be installed at the center of the processing chamber 121 on one side of the second window 14b, and the other end can be connected to the top of the second sealing frame 127; one end of the second pivot member 146 is installed at the bottom end of the processing chamber 121 on one side of the second window 14b, and the other end is connected to the center of the second sealing frame 127, so that the second sealing frame 127 can be flipped downward by driving the rotation of the pivot member 119, and can be placed according to the placement position of the denture engraving machine 100.

[0064] Please refer to Figure 2 、 Figure 12-13 As shown, preferably, the processing chamber 121 is provided with a second sealing groove 15b on the peripheral side of the second window 14b, and the second sealing frame 127 can be engaged with the second sealing groove 15b; the peripheral side of the opposite side of the second sealing frame 127 is engaged through the second sealing groove 15b to improve the sealing tightness between the second sealing frame 127 and the processing chamber 121 at the second window 14b.

[0065] Preferably, the second sealing frame 127 can be made of a transparent material. In this embodiment, quartz glass is selected to ensure structural stability while allowing the image inside the processing chamber 121 to be viewed through the second sealing frame 127 .

[0066] Example 3: Please refer to Figures 1 to 4 As shown, based on Examples 1 to 2, this embodiment provides a denture engraving machine 100, which includes: a sleeve, a calibration part 118 and a control main board 124, wherein the sleeve is the air guide sleeve 123 in Examples 1 to 2. For ease of understanding, this embodiment continues to use the "air guide sleeve 123".

[0067] Please refer to Figure 2-8As shown, preferably, the air guide sleeve 123 is installed on the main body 110, and the end of the air guide sleeve 123 is arranged opposite to the grinding disc 116. The calibration part 118 is used to calibrate the grinding disc 116. The calibration part 118 is installed at the end of the air guide sleeve 123. It can be understood that the grinding disc 116 in this embodiment is provided with a calibration disc for calibration on the side facing the calibration part 118, or the grinding disc 116 can be set as a calibration disc so as to achieve calibration work before the grinding work begins; the control main board 124 is used to control the calibration of the grinding disc 116 by the calibration part 118, and the control main board 124 is electrically connected to the calibration part 118; wherein, the calibration part 118 can move with the air guide sleeve 123 to move away from or approach and abut the grinding disc 116, and the calibration part 118 can feedback a calibration signal to the control main board 124 when abutting against the grinding disc 116.

[0068] According to the above scheme, it can be understood that the calibration of the grinding disc 116 by the calibration piece 118 is controlled by the control main board 124, so that when the calibration piece 118 moves with the air guide sleeve 123 and abuts against the grinding disc 116, the calibration piece 118 is electrically connected to the control main board 124, so that the calibration piece 118 can feedback the calibration signal to the control main board 124, confirming that the calibration of the grinding disc 116 is completed, so as to facilitate the next operation, replacing the traditional engraving machine that needs to rely on the complex operation method of manual calibration, reducing the difficulty of calibration, and improving the calibration efficiency, thereby further improving the processing accuracy and continuity.

[0069] Please refer to Figure 2-5 As shown, preferably, in some embodiments, the calibration piece 118 includes a calibration rod 131 and a conductive sheet 132 installed on the calibration rod 131, and the calibration rod 131 is the same as the calibration rod 131 in Examples 1 to 2, and the conductive sheet 132 is in contact with the air guide sleeve 123, and when the calibration rod 131 is in contact with the grinding disc 116, the conductive sheet 132 forms a short circuit with the grinding disc 116 and feeds back a short circuit signal to the control main board 124; it can be understood that when the calibration piece 118 is installed on the air guide sleeve 123, one end of the conductive sheet 132 is in contact with the conductive part on the air guide sleeve 123, and the control board is electrically connected to the calibration rod 131 through the air guide sleeve 123, so that After the engraving machine is running, power is supplied between the control main board 124 and the calibration rod 131. Since the calibration rod 131 is not in contact with the grinding disk 116 at this time, the conductive sheet 132 and the grinding disk 116 do not form a complete path. When the calibration rod 131 is in contact with the grinding disk 116 as the air guide sleeve 123 moves, the grinding disk 116 and the calibration rod 131 are connected to each other, so that the conductive sheet 132 and the grinding disk 116 form a short circuit, and a short-circuit signal is fed back to the control main board 124. After receiving the short-circuit signal, the control main board 124 can determine that the calibration rod 131 has calibrated and positioned the grinding disk 116, thereby determining the position coordinates of the grinding disk 116.

[0070] Please refer to Figure 2-4 、 Figure 6 As shown, preferably, in other embodiments, the calibration member 118 includes a calibration rod 131 and a sensor 133 installed on the calibration rod 131, one end of the sensor 133 abuts against the air guide sleeve 123, and the other end can abut against the grinding disc 116 as the calibration rod 131 abuts against the grinding disc 116 and feed back an abutment signal to the control main board 124. It can be understood that when the calibration member 118 is installed on the air guide sleeve 123, the sensor 133 is electrically connected to the control main board 124, and when the calibration rod 131 abuts against the grinding disc 116 as the air guide sleeve 123 moves, the sensor 133 is electrically connected to the control main board 124. At this time, the sensor 133 will receive the contact signal between the calibration rod 131 and the grinding disk 116, and feedback the contact signal to the control motherboard 124. The control motherboard 124 can determine that the calibration rod 131 calibrates and positions the grinding disk 116 upon receiving the contact signal, thereby determining the position coordinates of the grinding disk 116; it is understandable that when the calibration rod 131 separates from the grinding disk 116 as the air guide sleeve 123 moves, the sensor 133 does not receive the contact signal between the calibration rod 131 and the grinding disk 116, and thus will not feedback the contact signal to the control motherboard 124.

[0071] In the above solution, preferably, the sensor 133 is configured as a touch sensor 133 , and the touch sensor 133 is a pressure sensor 133 .

[0072] Optionally, in other embodiments, the sensor 133 may also be configured as a laser sensor 133 .

[0073] Please refer to Figure 2-4 、 Figure 7 As shown, preferably, in some other embodiments, the calibration member 118 includes a calibration rod 131 and a gear member 134 installed on the calibration rod 131, and the gear member 134 is electrically connected to the control main board 124. It can be understood that the gear member 134 is set as a gear adjustment member, and the gear adjustment member can be set as a button, or a trigger switch and other gear adjustment components. By installing it at the end of the calibration rod 131, when the calibration rod 131 moves with the air guide sleeve 123 and abuts against the grinding disc 116, At this time, the gear member 134 will be triggered or acted upon to adjust the gear position, and the gear adjustment signal will be fed back to the control motherboard 124. The control motherboard 124 can determine that the calibration rod 131 has calibrated and positioned the grinding disc 116 upon receiving the abutment signal, thereby determining the position coordinates of the grinding disc 116; it is understandable that when the calibration rod 131 is separated from the grinding disc 116 as the air guide sleeve 123 moves, the gear member 134 is not triggered or acted upon, and thus returns to its original gear position to prepare for the next calibration.

[0074] Please refer to Figure 5As shown, preferably, the calibration piece 118 also includes a limiting piece 135, and the calibration rod 131 is provided with an embedding groove 13a for the limiting piece 135 to be embedded, and the limiting piece 135 is embedded in the embedding groove 13a and is adjacent to the conductive piece 132; the purpose of providing the limiting piece 135 is to limit the conductive piece 132 so that the conductive piece 132 is squeezed and fixed; in addition, the calibration rod 131 is further provided with a limiting protrusion 136, and the limiting protrusion 136 is provided on one side of the embedding groove 13a and is spaced apart from the embedding groove 13a, and the conductive piece 132 is clamped between the limiting protrusion 136 and the limiting piece 135 installed in the embedding groove 13a. This structure is to enhance the fixing effect of the conductive piece 132, so that the conductive piece 132 can play a role in stably abutting the conductive part of the air guide sleeve 123, thereby maintaining its function of stably transmitting short-circuit signals.

[0075] Please refer to Figure 9 As shown, preferably, the denture engraving machine 100 also includes a tool holder 125, which is provided with a plurality of loading slots 13b connected to the outside, and a plurality of calibration rods 131 are provided, and each calibration rod 131 is detachably installed in the loading slot 13b; further, the tool holder 125 is provided with a first switch 137 and a second switch 138, the first switch 137 is used to fix the corresponding calibration rods 131 in all loading slots 13b, and the second switch 138 is used to pop out the corresponding calibration rods 131 in all loading slots 13b; further, the tool holder 125 also includes digital buttons 139, the number of digital buttons 139 corresponds to the number of loading slots 13b, any digital button 139 corresponds to a loading slot 13b, and any digital button 139 is used to pop out the calibration rod 131 in the corresponding loading slot 13b.

[0076] To sum up, the utility model provides a denture engraving machine, which maintains good sealing of the processing chamber during the operation of the main shaft by setting a first sealing frame, and also realizes the operation of the processing chamber without affecting the sealing effect by setting a second sealing frame, thereby improving the sealing performance and convenience of the denture engraving machine, so as to achieve the effect of improving processing accuracy and continuity.
