Description

Technical Field

[0001] The invention relates to the technical field of denture processing, in particular to a clamping and fixing device for processing zirconia dentures. Background Art

[0002] The oxidation process of zirconia dentures is only one step in the overall processing flow. Before this, multiple processes such as grinding, polishing, and cleaning must be completed. Among these processes, the clamping and fixing of zirconia dentures is a key step. As shown in the authorization announcement number CN 220408209 U, the patent adopts the following clamping method: first, the denture is placed on the abutment plate 205, and the anti-slip pad 2014 is made to correspond to the two ends of the denture by moving the two movable plates 2013, and the sleeve plate 203 and the movable plate 2013 are fixed with bolts 2012; then, the rotating disk 207 is rotated to drive the screw 208 to rotate, driving the screw sleeve 206 to move, and finally, the anti-slip pad 2014 is pushed to fit tightly with the denture through the connecting rod 209 to complete the clamping.

[0003] However, this type of clamping structure has significant drawbacks: while the combination of the abutment plate 205 and the anti-slip pad 2014 can achieve a secure fit, the contact area between the abutment plate 205 and the denture is excessively large. During polishing and other processes, especially oxidation, the operator must repeatedly remove and reattach the denture to process the surface covered by the clamping components. This clamping method significantly reduces overall processing efficiency. Summary of the Invention

[0008] The chassis and the support rod are an integrally formed structure. The chassis is provided with an adapting hole, and the base plate is provided with a screw hole. The chassis is fixed on the base plate by bolts, and the base plate is provided with an avoidance hole.

[0009] As a preferred solution of the clamping and fixing device for zirconia denture processing described in the present invention, wherein: the outer surface of the support rod is sleeved with a rod sleeve, the adapting thread on the outer surface of the rod sleeve is in contact with the external thread of the support rod, a concave ring is provided at the junction of the support rod and the chassis, the bottom of the rod sleeve extends to the concave ring, and a cable tie is provided on the concave ring to ensure that the rod sleeve is sealed against the outer surface of the support rod.

[0010] As a preferred solution of the clamping and fixing device for zirconia denture processing described in the present invention, wherein: the inner cavity of the support rod is provided with an air inlet hole connected to the rod sleeve, the inner cavity of the support rod is provided with a threaded sleeve, the threaded sleeve is provided with a threaded drive rod, one end of the threaded drive rod located in the inner cavity is provided with a piston block through a bearing, the piston block slides sealingly on the inner wall of the support rod, and the other end of the threaded drive rod is provided with a rotating disk.

[0011] As a preferred solution of the clamping and fixing device for processing zirconia dentures described in the present invention, the air inlet is located between the top of the support rod and the piston block.

[0012] As a preferred solution of the clamping and fixing device for zirconia denture processing described in the present invention, the rod sleeve is made of silicone and the thickness of the rod sleeve is between 0.05-0.1 mm.

[0013] As a preferred solution of the clamping and fixing device for zirconia denture processing described in the present invention, the substrate is arranged in a limiting slot of the tray, and the limiting slot is provided with an opening, and a locking assembly is provided on the tray, and the substrate is fixed to the tray through the locking assembly.

[0014] As a preferred solution of the clamping and fixing device for processing zirconia dentures described in the present invention, a plurality of limiting slots are provided on the tray at equal intervals, and the tray is in the shape of a bar or a rectangle.

[0015] As a preferred solution of the clamping and fixing device for zirconia denture processing described in the present invention, the locking assembly includes a rotating seat, a support arm, a screw rod, a cross handle and a pressure plate. The rotating seat is fixed on the top of the tray and located at both ends of the limiting slot. The number of the rotating seats is at least two.

[0016] As a preferred solution of the clamping and fixing device for zirconia denture processing described in the present invention, the rotating seat is fixedly connected to one end of the support arm, the other end of the support arm is threadedly sleeved with a screw, the top of the screw is provided with a cross handle, and the bottom of the screw is provided with a pressure plate, and the cross handle is rotated to squeeze the pressure plate onto the upper surface of the substrate.

[0017] The beneficial effects of the present invention are as follows: the support rod with the rod sleeve is assembled with the thread groove of the denture, and before that, the air in the rod sleeve and the support rod is emptied by driving the piston block to move outward. After assembly, the piston block is driven inward to fill the rod sleeve and the support rod with air, so that the expanded rod sleeve is interposed between the support rod and the thread groove of the denture, effectively protecting the thread structure of the thread groove of the denture, supporting the denture while the outer surface of the denture is completely exposed, and there is no need to repeatedly disassemble and re-fix the denture;

[0018] During polishing, the rod sleeve is made of silicone and the thickness of the rod sleeve is between 0.05-0.1mm. The denture will swing due to the air filling between the rod sleeve and the support rod. However, since the thickness of the rod sleeve is very thin, the swing amplitude is sufficient for polishing. At the same time, such a small swing helps to offset the vibration, thereby protecting the denture structure.

[0019] During oxidation and spraying processes, the air filling between the rod sleeve and the support rod can have an isolation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0035] Example

[0036] Reference Figures 1 to 8 , is an embodiment of the present invention, which provides a clamping and fixing device for processing zirconia dentures, including a support assembly 400, the bottom of the support assembly 400 is set on the base plate 300, the support assembly 400 is provided with a control assembly 500, the top of the support assembly 400 is provided with a rod sleeve 405, the support assembly 400 and the control assembly 500 cooperate to separate the rod sleeve 405 from the outer surface of the support assembly 400;

[0037] Specifically, the support assembly 400 includes a chassis 401 and a support rod 402; the control assembly 500 includes a piston block 501, a threaded drive rod 502, a bearing 502a, a screw sleeve 503, and a rotating disk 504;

[0038] The chassis 401 and the support rod 402 are an integrally formed structure. The chassis 401 is provided with an adaptation hole 401a, and the base plate 300 is provided with a screw hole 301. The chassis 401 is fixed to the base plate 300 by a bolt 401b. The base plate 300 is provided with an avoidance hole 302. The bolt 401b is inserted into the adaptation hole 401a and threadedly connected to the screw hole 301 to fix the integrally formed structure of the chassis 401 and the support rod 402 on the base plate 300.

[0039] The outer surface of the support rod 402 is sleeved with a rod sleeve 405, and the adapting thread 405a on the outer surface of the rod sleeve 405 fits with the external thread 404 of the support rod 402. A concave ring 402c is provided at the junction of the support rod 402 and the chassis 401. The bottom of the rod sleeve 405 extends to the concave ring 402c, and a cable tie 403 is sleeved on the concave ring 402c to seal the rod sleeve 405 and the outer surface of the support rod 402. An air inlet 402b is provided in the inner cavity 402a of the support rod 402 and is connected to the rod sleeve 405. The inner cavity 402a of the support rod 402 is provided with a screw sleeve 503, and the screw sleeve 503 is threadedly sleeved with a threaded drive rod 502. One end of the threaded drive rod 502 located in the inner cavity 402a is provided with a piston block 501 through a bearing 502a. The piston block 501 slides sealingly on the inner wall of the support rod 402, and the other end of the threaded drive rod 502 is provided with a rotating disk 504.

[0040] The rotating disk 504 allows the threaded driving rod 502 to rotate downward under the threaded connection of the threaded sleeve 503, so that the piston block 501 supported by the bearing 502a moves downward to extract the air in the inner cavity 402a of the support rod 402, so that the adapting thread 405a of the rod sleeve 405 is tightly fitted with the external thread 404 of the support rod 402, and is now threadedly assembled with the thread groove of the artificial tooth 600 to be processed. Then, the piston block 501 is moved upward in the opposite direction to squeeze the air in the inner cavity 402a of the support rod 402, so that the expanded rod sleeve 405 is located between the support rod 402 and the thread groove of the artificial tooth 600 to be processed, forming a barrier. At the same time, the air inlet hole 402b is always located between the top of the support rod 402 and the piston block 501 to ensure air tightness.

[0041] Furthermore, the rod sleeve 405 is made of silicone and the thickness of the rod sleeve 405 is between 0.05-0.1mm, so that the expanded rod sleeve 405 forms a thinner layer between the support rod 402 and the thread groove of the denture 600 to be processed, so that the denture 600 to be processed does not have the problem of loose fixation during polishing and grinding. At the same time, the slight swing is conducive to offsetting vibration, thereby having a protective effect on the structure of the denture 600 to be processed.

[0042] The substrate 300 is arranged in the limiting slot 101 of the tray 100, and the limiting slot 101 is provided with an opening 102. A locking assembly 200 is provided on the tray 100, and the substrate 300 is fixed on the tray 100 through the locking assembly 200. The avoidance hole 302 of the substrate 300 and the opening 102 provided in the limiting slot 101 of the tray 100 are both for the convenience of operation and setting of the rotating disk 504.

[0043] Several limit slots 101 are provided at equal intervals on the tray 100. The tray 100 is strip-shaped or rectangular. The tray 100 has multiple limit slots 101 and corresponding locking assemblies 200 for fixing and accommodating more support assemblies 400 fixed on the base plate 300, so as to realize the processing of more dentures 600 to be processed.

[0044] The locking assembly 200 fixes the support assembly 400 fixed on the base plate 300 to the tray 100 through a movable installation method, making it convenient to take out the denture 600 for processing;

[0045] Specifically, the locking assembly 200 includes a rotating seat 201, a support arm 202, a screw rod 203, a cross handle 204 and a pressure plate 205. The rotating seat 201 is fixedly mounted on the top of the tray 100 and located at both ends of the limiting slot 101. There are at least two rotating seats 201. The rotating seat 201 is fixedly connected to one end of the support arm 202. The other end of the support arm 202 is threadedly sleeved with a screw rod 203. The top of the screw rod 203 is provided with a cross handle 204. The bottom of the screw rod 203 is provided with a pressure plate 205. The cross handle 204 is rotated to press the pressure plate 205 against the upper surface of the base plate 300.

[0046] During use, the denture 600 to be processed is fixed on the support assembly 400 fixed on the base plate 300, the base plate 300 is placed in the limit slot 101 of the tray 100 and is fully engaged, the support arm 202 is rotated to rotate under the support of the rotating base 201, and the pressure plate 205 at the other end is aligned with the upper surface of the base plate 300, and then the cross handle 204 is rotated to rotate and move the screw rod 203 downward, so that the pressure plate 205 presses the surface of the base plate 300, and the denture 600 to be processed is fixed on the tray 100;

[0047] It is worth mentioning that by fixing most of the dentures 600 to be processed on the tray 100, the batch processing process (grinding, polishing, cleaning and oxidation, etc.) of the dentures 600 to be processed can be carried out and the dentures 600 to be processed will not be taken out until the end. This process greatly reduces the problem of low efficiency of the processing process due to excessive contact between the dentures 600 and their surfaces during the clamping process of the existing technology, which requires repeated disassembly and re-fixing of the dentures.
