Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, specifically to a dental prosthesis processing fixture and dental prosthesis processing equipment. Background Technology

[0002] During the denture processing, the fixture needs to be fixed on the rotating shaft first to facilitate the adjustment of the processing angle of the sample.

Detailed Implementation

[0043] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0044] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0045] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] In view of the shortcomings of the prior art, this embodiment provides a denture processing fixture and denture processing equipment, which can be referred to as follows:

[0047] As attached Figure 1As shown, a denture processing fixture includes a square plate fixture 1, an extension fixture 2, and a fixing member 3. The square plate fixture 1 is fixed to the rotating shaft of the denture processing equipment for mounting square plate samples. The extension fixture 2 is detachably mounted on the surface of the square plate fixture 1 for mounting titanium rods or glass ceramics. The fixing grooves 21 on both sides of the extension fixture 2 cooperate with the square plate fixture 1, so that the mounting position of the extension fixture 2 is lower than the surface and located on the axis of the rotating shaft of the denture processing equipment. The fixing member 3 realizes the positioning connection between the two.

[0048] The square plate clamp 1 refers to a rigid support structure with a rotating shaft mounting interface on the denture processing equipment. Specifically, it can be a U-shaped frame made of cast aluminum alloy, with steps 14 on its inner wall for placing the square plate sample. The extension clamp 2 refers to a detachable module with material mounting function, with grooves machined on both sides to match the shape of the ends of the square plate clamp 1. The mounting position being lower than the surface means that the material fixing point of the extension clamp 2 forms a recessed space relative to the upper surface of the square plate clamp 1, which can be achieved by controlling the depth dimension of the fixing groove 21. The fastener 3 refers to the mechanical connection component that realizes the positioning and locking between modules. Specifically, it can be a combination structure of positioning pins and bolts, where the positioning pins constrain lateral displacement and the bolts provide axial clamping force.

[0049] Specifically, the square plate clamp 1 serves as the basic structure, remaining permanently fixed on the rotating shaft to complete routine processing tasks for the square plate sample. When processing titanium rods or glass ceramics is required, the extension clamp 2 is slid into the upper part of the square plate clamp 1 through the fixing grooves 21 on both sides, and mates with the surface of the square plate clamp 1, so that the mounting position of the extension clamp 2 is located on the axis of the rotating shaft. The positioning pin in the fixing member 3 is inserted into the preset pin hole 11 to complete the initial positioning, and then bolts are used to lock it to ensure the reliability of the connection. The mounting part 24 of the extension clamp 2 sinks into the inside of the square plate clamp 1, so that the fixing midpoint of the titanium rod or glass ceramic is at the same height as the axis of the rotating shaft. This structure allows for switching between processing different materials by quickly assembling and disassembling the extension module while retaining the basic clamp, without the need to recalibrate the axis position.

[0050] Compared with existing technologies, traditional methods require disassembling the entire fixture and reinstalling and calibrating it every time the processing material is changed, while this solution only requires replacing the expansion module and automatically maintains the same axis position.

[0051] Through the above technical solutions, this application effectively reduces the number of fixture replacements and calibration time, achieving multi-material processing compatibility while retaining the calibration status of the basic fixture. The quick assembly and disassembly of the expansion module avoids repeated disassembly and assembly of the basic structure, the cooperative design of the fixing slot 21 and the positioning pin eliminates the manual calibration process, and the sunken mounting position ensures the consistency of the axis of different processing objects, thereby significantly improving processing efficiency and reducing equipment idle wear.

[0052] As attached Figure 4 and attached Figure 5 As shown, this application further proposes that the fastener 3 includes a locating pin detachably disposed on the top wall of the fixing groove 21, and the surface of the square clamp 1 is provided with a pin hole 11 and a threaded hole 12, and the locating pin cooperates with the pin hole 11; the extension clamp 2 is provided with a connecting through hole 22, and the bolt passes through the connecting through hole 22 and the threaded hole 12 to form a threaded engagement.

[0053] The locating pin refers to a cylindrical metal insert that physically limits and constrains the horizontal displacement of the extended clamp 2. The pin hole 11 is a locating hole located in the square clamp 1, with its axis perpendicular to the axis of rotation. The connecting through hole 22 is a mounting hole for the extended clamp 2.

[0054] Specifically, when the extension clamp 2 needs to be installed, the locating pin is pre-inserted into the installation position on the top wall of the fixing groove 21. By inserting the locating pin into the pin hole 11, the installation position of the extension clamp 2 can be automatically aligned with the rotation axis. After horizontal positioning is completed, the axial coincidence of the connecting through hole 22 and the threaded hole 12 is ensured by the limiting action of the locating pin. At this time, the bolt passes through the connecting through hole 22 and screws into the threaded hole 12. The axial tensile force generated by the thread engagement presses the extension clamp 2 tightly onto the surface of the square clamp 1, forming a rigid connection with three points of force.

[0055] Through the above technical solution, this application eliminates the need for coaxial calibration using specialized measuring tools when replacing the extended fixture 2. Precise positioning can be achieved simply by inserting the locating pin and tightening the bolts. The physical limiting effect of the locating pin eliminates errors from manual adjustment, and the through-type connection of the bolts ensures consistent installation across different batches of fixtures, thereby effectively reducing fixture replacement time.

[0056] As attached Figure 4 and attached Figure 5 As shown, this application further proposes an extended clamp 2 including two mating parts 23, a mounting part 24, and a mounting hole group. The mounting part 24 is disposed between the two mating parts 23. The two mating parts 23 are respectively located at both ends of the mounting part 24 and cooperate with the mounting part 24 to form a fixing groove 21. The mounting part 24 is located inside the square clamp 1. The mounting hole group is disposed at the mounting position of the mounting part 24 and is located on the side of the mounting part 24 facing the opening of the square clamp 1, for mounting titanium rods or glass ceramics.

[0057] The contour of the mating part 23 forms a shape fit with both ends of the square clamp 1. This structure achieves automatic alignment of the axis of the extended clamp 2 with the rotation axis through physical positioning. The mounting part 24 is the intermediate support component connecting the two mating parts 23. This structure achieves vertical positioning of the extended clamp 2 by contacting the two end faces of the square clamp 1. The mounting position is the material fixing area located on the opening side of the mounting part 24, which can be formed by drilling or slotting. This positional layout ensures that the centerline of the material being processed coincides with the rotation axis.

[0058] Specifically, when the extended clamp 2 is installed onto the surface of the square clamp 1, the fixing groove 21 formed by the mating part 23 wraps around the two ends of the square clamp 1, forcing the extended clamp 2 to remain fixed in the radial direction along the rotation axis. The mounting part 24 is embedded in the internal cavity of the square clamp 1, and its open side mounting position is directly exposed to the processing area. When the titanium rod or glass ceramic is fixed in the mounting position, the material centerline is automatically aligned with the rotation axis due to the built-in structure of the mounting part 24. The depth design of the fixing groove 21 causes the extended clamp 2 to sink as a whole after installation, ensuring that the processed material is on the rotation axis.

[0059] Through the above technical solution, this application achieves rapid switching of processing material types while retaining the original fixture, eliminates the accumulation of positioning errors during fixture assembly and disassembly, and significantly reduces the coaxial calibration time after material change. Titanium rods and glass ceramics are fixed in separate areas through different mounting positions, simultaneously meeting the processing needs of metal cutting and ceramic engraving, avoiding the need for frequent changes of the entire fixture set when processing different materials.

[0060] As attached Figure 2 and attached Figure 4 As shown, this application further proposes a mounting hole assembly including a plurality of first fixing holes 25, a plurality of countersunk holes 26, and connecting bolts. The first fixing holes 25 are spaced apart on the side of the mounting portion 24 facing the opening of the square clamp 1, for inserting titanium rods. The countersunk holes 26 are spaced apart on the side of the mounting portion 24 away from the opening of the square clamp 1, corresponding one-to-one with the first fixing holes 25. The connecting bolts are disposed within the countersunk holes 26, connected to the titanium rods, and fix the titanium rods within the first fixing holes 25.

[0061] The first fixing hole 25 is a positioning hole located on the front side of the mounting part 24 to accommodate the titanium rod. The countersunk hole 26 is a stepped hole located on the back side of the mounting part 24 and extending coaxially with the first fixing hole 25, providing installation space for the connecting bolts.

[0062] Specifically, after the titanium rod is inserted into the first fixing hole 25, the connecting bolt passes through the countersunk hole 26 and is threaded to the end of the titanium rod. When the connecting bolt is tightened, the titanium rod is pulled back, and its front outer wall forms a surface contact with the inner wall of the first fixing hole 25. The enlarged structure of the countersunk hole 26 allows the bolt head to be completely recessed into the back side of the mounting part 24, avoiding contact with the surface of the square clamp 1. The operating space on the back side of the mounting part 24 allows for tightening operations to be performed while the clamp is installed, and the titanium rod can be fixed without disassembling the clamp.

[0063] Through the above technical solution, this application achieves reliable fixation of the titanium rod during the rotary machining process, avoiding calibration interruptions caused by material displacement. Simultaneously, the back-side countersunk hole 26 and the independent fastening structure allow for quick disassembly and replacement of different titanium rods, enabling material switching without the need for complete disassembly of the entire fixture, significantly shortening the preparation time between different machining tasks.

[0064] As attached Figure 3 and attached Figure 4 As shown, this application further proposes that the mounting hole group also includes a plurality of second fixing holes 27, which are spaced apart on the side of the mounting part 24 facing the opening of the square clamp 1, for placing ceramic glass. The second fixing holes 27 are located between two adjacent first fixing holes 25. A plurality of set screw holes 28 are provided on the top of the mounting part 24, and the set screw holes 28 are connected to the second fixing holes 27. The set screws are provided in the set screw holes 28 and abut against the ceramic glass to fix the ceramic glass in the second fixing holes 27.

[0065] The second fixing hole 27 refers to a cylindrical hole on the surface of the mounting part 24, whose spacing is limited between two adjacent first fixing holes 25, to avoid fixture changes when processing different materials. The set screw hole 28 refers to a threaded through hole perpendicular to the axis of the second fixing hole 27.

[0066] Specifically, the alternating arrangement of the second fixing hole 27 and the first fixing hole 25 allows the titanium rod and the glass-ceramic workpiece to be alternately fixed on the same mounting part 24, eliminating the need to change fixtures during the processing of the two materials. When mounting the ceramic glass, the workpiece is placed into the second fixing hole 27, and the set screw is screwed in through the set screw hole 28 and contacts the side wall of the workpiece. The radial component force generated by the tapered end face presses the workpiece against the hole wall. Since the set screw hole 28 and the second fixing hole 27 are connected and their axes are orthogonal, the clamping force direction is perpendicular to the workpiece axis, avoiding local stress concentration in brittle materials. The alternating distribution of the first fixing hole 25 and the second fixing hole 27 on the mounting part 24 ensures that the clamping positions of both workpieces are on the axis of rotation, eliminating the need to recalibrate the coaxiality of the equipment when processing different materials.

[0067] Through the above technical solution, this application achieves alternating processing of titanium rods and glass ceramics on the same fixture. When processing different materials, only the workpiece needs to be changed without disassembling the fixture, and the positioning of the equipment's rotation axis is continuously maintained. The adjustable characteristics of the set screw adapt to ceramic glass of different diameters, and the threaded locking method avoids the crushing damage to brittle materials caused by the traditional fixture pressure plate structure. The coaxial arrangement of the second fixing hole 27 and the first fixing hole 25 ensures that no repeated calibration is required when processing the two types of workpieces, and continuous processing of multiple materials can be completed in a single clamping.

[0068] This application further proposes that the centers of a plurality of first fixing holes 25 and a plurality of second fixing holes 27 are located on the axis of the rotating shaft of the denture processing equipment.

[0069] Through the above technical solution, this application realizes automatic centering and positioning when clamping titanium rods and ceramic glass. When changing materials during processing, there is no need to interrupt the equipment for coaxiality calibration, which effectively shortens the downtime waiting time when changing workpieces and avoids the accumulation of positioning errors caused by manual adjustment.

[0070] As attached Figure 4 As shown, this application further proposes to provide a positioning rod 29 on one side of the second fixing hole 27, the positioning rod 29 cooperating with the ceramic glass.

[0071] The positioning rod 29 refers to a rigid protrusion fixed to the side wall of the second fixing hole 27. It can be a cylindrical pin or a prism structure, and its end forms an abutment surface that matches the edge contour of the ceramic glass.

[0072] Specifically, when installing ceramic glass, the operator guides it along the positioning rod 29 and pushes it into the second fixing hole 27. The positioning rod 29 cooperates with the slot on the ceramic glass, thereby restricting the direction of the ceramic glass and preventing it from tilting or rotating.

[0073] Through the above technical solution, this application solves the problem of repeated calibration caused by ceramic glass installation misalignment, and changes the positioning accuracy of the ceramic glass blank on the fixture from relying on operational experience to being guaranteed by the mechanical structure.

[0074] As attached Figure 6 As shown, this application further proposes a square plate clamp 1 including a U-shaped part 13, a step 14, a pressure plate, and a slot 15. Both ends of the U-shaped part 13 are disposed on the rotating shaft of the denture processing equipment; the step 14 is disposed on the inner wall of the U-shaped part 13 for placing the square plate sample; the pressure plate is detachably disposed on the surface of the U-shaped part 13 for abutting against the square plate sample; the step 14 has a slot 15 at a position corresponding to the rotating shaft of the denture processing equipment, and the extension clamp 2 is located in the slot 15.

[0075] The U-shaped section 13 refers to a metal frame with a symmetrical support structure, whose two ends are rigidly connected to the rotating shaft by bolts. The step 14 refers to a stepped protrusion on the inner wall of the U-shaped section 13, the height of which matches the thickness of the square plate sample, forming a stable support surface. The pressure plate refers to a clamping component covering the surface of the U-shaped section 13, which can be implemented using an L-shaped steel plate with adjusting bolts; tightening the bolts generates downward pressure to fix the square plate. The slot 15 is a vertical notch penetrating the step 14.

[0076] Specifically, the square sample is placed on the planar area of ​​step 14, and the pressure plate quickly fixes the sample edge by bolts. The rigid connection between the two ends of the U-shaped part 13 and the rotating shaft ensures the overall coaxiality of the fixture and avoids radial offset during processing. The slot 15 in the step 14 area facilitates the insertion of the expansion fixture 2. When it is necessary to switch fixtures, the expansion fixture 2 is directly inserted into the slot 15 and connected by the fastener 3, without the need to recalibrate the axis position.

[0077] This application also proposes a denture processing device, including the aforementioned denture processing fixture.
