Specific embodiments

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figure 1-7 , an engraving machine for denture production, including a multi-axis traveling module 11 and a main spindle box 12 assembled on the multi-axis traveling module 11, and an engraving cutter head 13 is assembled on the main spindle box 12.

[0044] It further includes a loading and unloading component 2, a positioning component, and a processing pad table 4 arranged below the multi-axis traveling module 11. The loading and unloading component 2 is used to transfer the processing pad table 4, and the positioning component is assembled on the loading and unloading component 2 and is used to fix the processing pad table 4. The denture blank to be processed is fixedly assembled on the processing pad table 4.

[0045] The loading and unloading component 2 includes: a transmission bracket 21, synchronous wheels 22 rotatably installed at both ends of the transmission bracket 21, a synchronous belt 23 wound around the synchronous wheels 22, a cleaning brush wheel 24 rotatably installed on the transmission bracket 21 and arranged in contact with the outer surface of the synchronous belt 23, and a driving motor 25 that is in power connection with the synchronous wheels 22 and the cleaning brush wheel 24; the processing pad table 4 is slidably installed on the transmission bracket 21 and is in contact with the outer side surface of the synchronous belt 23.

[0046] The positioning component includes a horizontal positioning mechanism and a vertical positioning mechanism assembled at the middle position of the transmission bracket 21, and the horizontal positioning mechanism and the vertical positioning mechanism perform positioning and clamping on the processing pad table 4.

[0047] The multi-axis traveling module 11 can drive the spindle box 12 and the engraving cutter head 13 assembled on the spindle box 12 to travel stably along the X, Y, and Z axes. For engraving machines with higher requirements for engraving accuracy and efficiency, it can also drive the spindle box 12 to adjust the flipping angle around the X-axis and Y-axis directions, so that the engraving cutter head 13 can effectively act on each processing surface of the rough denture blank. The spindle box 12 drives the engraving cutter head 13 to rotate at a high speed to perform efficient and rapid processing operations on each processing surface of the rough denture blank, so as to complete all engraving processing steps in one loading and unloading operation process of the rough denture blank without stopping in the middle to change the positioning posture of the rough denture blank.

[0048] Since corresponding types of engraving cutter heads 13 are required for processing different parts of the rough denture blank, a tool disc that operates in cooperation with the multi-axis traveling module 11 is also provided. Various types of engraving cutter heads 13 are stored in the tool disc to facilitate the automatic replacement of the engraving cutter head 13 assembled on the spindle box 12 and ensure the efficiency of engraving the rough denture blank.

[0049] The loading and unloading component 2 is used to transfer the processing pad table 4 fixed with the rough denture blank from one end (loading position) of the transmission bracket 21 to the other end (unloading position). When it is conveyed to the middle position of the transmission bracket 21, the driving motor 25 stops, and stops driving the synchronous wheels 22, the synchronous belt 23, and the cleaning brush wheel 24 to operate, so that the processing pad table 4 is in a static state. Then, with the help of the horizontal positioning mechanism and the vertical positioning mechanism in the positioning component, the processing pad table 4 is accurately positioned, and the multi-axis traveling module 11, the spindle box 12, and the engraving cutter head 13 cooperate to operate to perform accurate and efficient processing operations on the rough denture blank fixed on the processing pad table 4, and produce qualified dentures for use.

[0050] After the denture is processed and completed, the positioning component is recycled and reset to cancel the positioning effect on the processing table 4. Then, the loading and unloading component 2 further operates to convey the processing table 4 and the finished denture fixed thereon to the unloading position. During this process, the processing table 4 and the rough denture newly input from the loading position of the transmission bracket 21 are circulated and transported to continuously carry out the engraving production work of the rough denture.

[0051] During the process of the synchronous belt 23 in the loading and unloading component 2 being driven by the driving motor 25 to operate, the cleaning brush wheel 24 can clean the processing debris falling on the synchronous belt 23, ensuring the cleanliness during the cyclic operation of the synchronous belt 23, and further ensuring the stability and accuracy of the conveyance of the next processing table 4.

[0052] To ensure the stable installation of the multi-axis traveling module 11 and the loading and unloading component 2 in space and achieve coordinated operation to efficiently process the rough denture, the following technical solutions are provided.

[0053] It further includes a processing machine table 5. The transmission bracket 21 is fixedly installed on the processing machine table 5, and a mounting bracket 51 is fixedly installed on the processing machine table 5. The multi-axis traveling module 11 is fixedly installed on the mounting bracket 51.

[0054] The setting of the processing machine table 5 and the mounting bracket 51 thereon can ensure the reasonable layout of the multi-axis traveling module 11 and the transmission bracket 21 in the loading and unloading component 2 in the three-dimensional space, ensure that the loading and unloading component 2 can stably convey the processing table 4 and the rough denture, and the multi-axis traveling module 11 cooperates with the main spindle box 12 and the engraving cutter head 13 to effectively process the rough denture.

[0055] To ensure isolation from the external environment during the engraving process of the rough denture, avoid interference of the rough denture by the external environment, and also avoid threats to the health of external staff caused by various functional components and processing debris during the processing of the rough denture, the following technical solutions are provided.

[0056] It further includes a protective cover 6. The protective cover 6 is fixedly installed on the processing machine table 5. An access opening 61 is provided on the front side of the protective cover 6, and a telescopic protective door 62 is slidably assembled at the access opening 61. Feeding openings 63 and discharging openings 64 are respectively provided on both sides of the protective cover 6, and both ends of the transmission bracket 21 are arranged opposite to the feeding opening 63 and the discharging opening 64 respectively.

[0057] The setting of the protective cover 6 can effectively separate the processing area of the rough denture from the external environment to ensure the stable processing of the pressurized rough material and ensure the personal safety of the surrounding staff.

[0058] The access opening 61 provided on the front side of the protective cover 6 facilitates the stable installation of functional components such as the multi-axis traveling module 11, the spindle headstock 12, the loading and unloading assembly 2, and the positioning assembly on the processing machine tool 5, or the disassembly and maintenance of the functional components. The telescopic protective door 62 is provided to facilitate the control of the opening and closing posture of the access opening 61.

[0059] The loading opening 63 and the unloading opening 64 provided on both sides of the protective cover 6 facilitate the delivery of the processing pad 4 fixed with the rough denture material to the loading position of the loading and unloading assembly 2, and facilitate the unloading operation of the processed denture finished product and the supporting processing pad 4 from the unloading position.

[0060] To ensure that the synchronous pulley 22, the synchronous belt 23, and the cleaning brush wheel 24 can be stably installed and operated on the transmission bracket 21, ensure that the processing pad 4 can travel stably in a straight line on the transmission bracket 21, and at the same time facilitate the cleaning of the debris generated during the processing, the following technical solutions are provided.

[0061] The transmission bracket 21 includes: an assembly bottom plate 211, two groups of limit baffles 212 fixedly connected to the assembly bottom plate 211 and arranged in parallel, and a support table 213 fixed to the inner sides of the two groups of limit baffles 212; a chip discharge opening 2131 is provided on the support table 213, and a cleaning opening 2121 is provided on the side wall of the limit baffle 212. The synchronous pulley 22, the synchronous belt 23, and the cleaning brush wheel 24 are all arranged inside the two groups of limit baffles 212.

[0062] Connecting shafts A221 are rotatably installed at both ends of the transmission bracket 21. Synchronous pulleys 22 are fixedly connected to both ends of the connecting shafts A221. The synchronous pulleys 22 at the same end of the two groups of connecting shafts A221 achieve power transmission through the synchronous belt 23, and the synchronous belt 23 is arranged on the support table 213.

[0063] A connecting shaft B241 is rotatably installed at one end of the transmission bracket 21. Cleaning brush wheels 24 are fixedly connected to both ends of the connecting shaft B241, and the cleaning brush wheels 24 are arranged below the support table 213.

[0064] The setting of the assembly bottom plate 211 can ensure the stable installation of the transmission bracket 21 on the processing machine tool 5, and make the transmission bracket 21 arranged in a horizontal posture. The limit baffles 212 can limit the transmitted processing pad 4, so that the processing pad 4 slides stably in a straight line inside the two groups of limit baffles 212. The two synchronous pulleys 22 at the same end of the transmission bracket 21 are synchronously rotated through the connecting shaft A221, thereby ensuring that the two synchronous belts 23 run synchronously. The upper processing pad 4 is stably supported by the two synchronous belts 23 and driven to travel stably inside the limit baffles 212.

[0065] The support platform 213 is provided to effectively support the upper part of the synchronous belt 23, ensuring that the upper part of the synchronous belt 23 runs stably in the horizontal straight line direction. The connecting shaft B241 and the cleaning brush wheel 24 are usually installed at one end of the loading position of the transmission bracket 21 to effectively clean the part of the synchronous belt 23 that is returned from the lower layer, ensuring the cleanliness of the outer surface of the synchronous belt 23 that is re-run to the upper layer, and thus ensuring the accuracy of the processing pad 4 transmitted thereon during the travel process.

[0066] A chip removal opening 2131 is provided on the support table 213. When the multi-axis moving module 11, the spindle box 12 and the engraving tool head 13 cooperate to process the denture rough material, the debris generated can fall onto the assembly base plate 211 through the chip removal opening 2131, and then the debris accumulated on the assembly base plate 211 can be cleaned through the cleaning opening 2121.

[0067] In order to ensure that the driving motor 25 can drive the synchronous wheel 22 and the cleaning brush wheel 24 to operate stably, and drive the synchronous belt 23 to operate while cleaning the outer surface of the synchronous belt 23, the following technical solution is provided.

[0068] The driving motor 25 is fixedly installed on the outer side of the limit baffle 212, and a driving bevel gear 251 is fixedly connected to the output shaft of the driving motor 25, and a transmission bevel gear 222 that is meshed with the driving bevel gear 251 is fixedly connected to one set of connecting shafts A221, and a reversing gear A223 and a reversing gear B242 are respectively fixedly connected to the same end of one set of connecting shafts A221 and a connecting shaft B241, and the reversing gear A223 and the reversing gear B242 are meshed.

[0069] When the driving motor 25 is working, it drives the driving bevel gear 251 to operate, and then drives the corresponding connecting shaft A221 and the synchronous wheel 22 thereon to operate stably through the transmission bevel gear 222, and drives another set of connecting shafts A221 and synchronous wheels 22 to operate through the combination of the synchronous wheel 22 and the synchronous belt 23, so as to ensure the continuous and stable operation of the synchronous belt 23.

[0070] On this basis, through the combination of reversing gear A223 and reversing gear B242, the power of the driving motor 25 can be transmitted from the connecting shaft A221 to the connecting shaft B241, thereby driving the cleaning brush wheel 24 to operate, so as to effectively clean the outer surface of the synchronous belt 23 during operation.

[0071] Since the inner side surface of the synchronous belt 23 is located inside the support platform 213, it will not be contaminated by the debris generated by the processing, and the cleaning work of the inner side surface of the synchronous belt 23 is not considered.

[0072] To prevent the debris generated during the processing from invading the driving motor 25 and the tooth gaps of each gear and affecting its normal operation, a dust cover A214 and a dust cover B215 are assembled on the outer side of the limit baffle 212 in a detachable manner. The dust cover A214 covers the driving motor 25, the driving bevel gear 251, and the transmission bevel gear 222 to prevent debris from invading, and the dust cover B215 covers the two groups of reversing gears to prevent debris from invading.

[0073] To ensure that the lateral positioning mechanism can be stably installed on the transmission bracket 21 and effectively position the processing pad table 4, the following technical solutions are provided.

[0074] The lateral positioning mechanism includes two groups arranged symmetrically. The two groups of lateral positioning mechanisms are respectively assembled on the side walls of the two groups of limit baffles 212, and two groups of guide chutes 2122 are fixedly connected to the side walls of each group of limit baffles 212.

[0075] Each group of lateral positioning mechanisms includes a connecting plate 311, a positioning cylinder A312, and two positioning keys 313. The two positioning keys 313 are slidably installed in the guide chute 2122. The connecting plate 311 is fixedly connected to the two positioning keys 313. The positioning cylinder A312 is fixedly installed on the transmission bracket 21, and the connecting plate 311 is fixedly connected to the movable end of the positioning cylinder A312.

[0076] A positioning slot 41 that is nested and clamped with the positioning key 313 is provided on the side wall of the processing pad table 4.

[0077] The setting of the guide chute 2122 can ensure that the positioning key 313 slides telescopically in a direction perpendicular to the limit baffle 212. A horizontally arranged mounting sleeve 2123 is fixedly connected to the two limit baffles 212. The positioning cylinder A312 is fixedly installed in the mounting sleeve 2123 to ensure the stable operation of the positioning cylinder A312. When the positioning cylinder A312 extends, it can drive the connecting plate 311 and the positioning key 313 to move outwards. At this time, the positioning key 313 slides out from the inside of the limit baffle 212 to cancel the positioning effect on the positioning slot 41 in the processing pad table 4 here. When the positioning cylinder A312 contracts, it can drive the positioning key 313 to move towards the inside of the limit baffle 212, and then realize the matching clamping with the positioning slot 41 to achieve the preliminary positioning of the processing pad table 4.

[0078] It should be emphasized that both sides of the positioning slot 41 and the positioning key 313 are provided with wedge-shaped surfaces. When the loading and unloading transmission assembly transports the processing pad table 4 here, there are often small errors, resulting in the positioning slot 41 and the positioning key 313 not being perfectly opposite. Through the setting of the wedge-shaped surface, the position of the processing pad table 4 on the transmission bracket 21 can be accurately positioned by means of the telescopically moving positioning key 313.

[0079] It should also be emphasized that since the height position of the processing pad table 4 is prone to jitter when the synchronous belt 23 transports the processing pad table 4, the thickness of the positioning card slot 41 is greater than the thickness of the positioning key 313. The existing thickness redundancy enables the positioning key 313 to effectively penetrate into the positioning card slot 41 to position the horizontal position of the processing pad table 4, while ensuring that the vertical position of the processing pad table 4 is still adjustable.

[0080] To ensure that the vertical positioning mechanism can be stably installed on the transmission bracket 21 and effectively position the processing pad table 4, the following technical solutions are provided.

[0081] Two sets of limit baffles 212 are fixedly connected with assembly wing plates 2124 arranged symmetrically, and two sets of vertical positioning mechanisms are assembled on each group of assembly wing plates 2124.

[0082] Each set of vertical positioning mechanisms includes a positioning cylinder B321 and a positioning pin rod 322. The positioning cylinder B321 is fixedly installed on the assembly wing plate 2124 and arranged in the vertical direction, and the positioning pin rod 322 is fixedly connected to the movable end of the positioning cylinder B321.

[0083] The processing pad table 4 is provided with a positioning pin hole 42 that is nested and clamped with the positioning pin rod 322.

[0084] The setting of the assembly wing plate 2124 can ensure the stable installation of the positioning cylinder B321 in the vertical direction and avoid interfering with the transmission movement of the processing pad table 4.

[0085] When the positioning cylinder B321 extends, it drives the positioning pin rod 322 to move downward and insert into the positioning pin hole 42 of the processing pad table 4. The processing pad table 4 preliminarily positioned by the horizontal positioning mechanism restricts its lateral movement, and then through the further action of the vertical positioning mechanism, the vertical movement of the processing pad table 4 can be restricted.

[0086] Through the cooperation of the horizontal positioning mechanism and the vertical positioning mechanism, accurate positioning of the processing pad table 4 can be achieved, ensuring accurate processing of the false tooth blanks fixed thereon.
