[0040] Example

[0041] Before a denture is fully produced, it needs to go through multiple processing steps, including carving, polishing, etc. The manufacturer needs to form the corresponding groove on the crown by carving and milling, and then polish it to keep the crown surface smooth. In the above process, the denture needs to be positioned. In the existing technology, it is usually operated by holding it or placing it on the overall model of the original teeth. In actual production, the efficiency cannot be further improved, or it is limited by the need to operate on the overall model of the original teeth, which is inconvenient. In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0042] For details, see Figure 1-3 , this embodiment provides a denture processing positioning mechanism, including a positioning assembly 10; the positioning assembly 10 includes a fixed disk 11, a rotating disk 12, a rotating rod 13, a positioning column 14, a connecting shaft 16 and a rotating drive member 15;

[0043] Specifically, the rotary drive member 15 is provided on the fixed disk 11, and the connecting shaft 16 is provided at the driving end of the rotary drive member 15. The connecting shaft 16 is fixedly connected to the rotating disk 12 to drive the rotating disk 12 to rotate;

[0044] Furthermore, one end of the rotating rod 13 is rotatably disposed on the fixed disk 11 and is located between the rotating disk 12 and the fixed disk 11, and the other end is connected to the positioning column 14;

[0045] Specifically, an arc-shaped guide groove 121 is formed on the rotating disk 12 , and the positioning column 14 passes through the arc-shaped guide groove 121 and is confined in the arc-shaped guide groove 121 ;

[0046] Furthermore, there are at least two rotating rods 13 and positioning posts 14, and they are arranged in a one-to-one correspondence;

[0047] When the rotating disk 12 rotates, it is suitable for driving the plurality of positioning posts 14 to move closer to or away from each other with the axis of the rotating disk 12 as the center through the guide grooves;

[0048] In the above scheme, the crown is positioned at the positioning point of the groove body in the crown. In the initial state, multiple positioning posts 14 are retracted with each other. At this time, the positioning posts 14 can be accommodated in the groove body of the crown. Then the rotating drive member 15 is started. The rotating drive member 15 drives the rotating disk 12 to rotate through the connecting shaft 16. The rotating disk 12 uses the arc-shaped guide groove 121 thereon to guide the positioning posts 14 away from each other. Finally, the positioning posts 14 abut against the inner wall surface of the groove body of the crown, and the outside is exposed for subsequent processing. The scheme provided by the present application makes full use of the groove body structure of the crown to realize the positioning of the crown. It is easy to use and can stably fix the crown, which is convenient for subsequent stable processing.

[0049] For details, see Figure 2 The positioning column 14 includes a rod body 141 and a positioning end head 142 rotatably provided at the end of the rod body 141; the rotation plane of the positioning end head 142 is parallel to the radial plane of the rotating disk;

[0050] Specifically, a locking bolt 143 is provided at the rotation point of the positioning end 142 on the rod body 141;

[0051] In the above scheme, the positioning end head 142 in this scheme can be rotatably provided on the rod body 141, and the rotation plane of the positioning end head 142 is parallel to the radial plane of the rotating disk, that is, the positioning end head 142 can adjust its contact point with the inner wall surface of the crown groove when rotating; in this way, when encountering some crown grooves that are irregular grooves, the position of the positioning end head 142 can be adjusted so that multiple positioning end heads 142 can better abut against the inner wall surface of the crown groove to achieve good positioning and fixation; this scheme effectively improves the compatibility of the positioning mechanism and improves its scope of application.

[0052] Furthermore, the positioning end 142 is provided with anti-slip silicone;

[0053] In the above scheme, anti-slip silicone is provided on the positioning end 142, which can further enhance the relative friction between the positioning end 142 and the inner wall surface of the denture groove, thereby achieving better positioning and fixing effect; in addition, the anti-slip silicone also has a certain deformation ability, which can achieve a certain degree of positioning adaptation, effectively reducing the requirements for position adjustment of the positioning end 142.

[0054] Furthermore, anti-slip stripes are formed on the outer surface of the anti-slip silica gel.

[0055] Specifically, in one embodiment, the positioning end 142 is spherical;

[0056] In the above solution, the positioning end 142 is spherical, so that it can better abut against the inner wall surface of the crown groove when performing multiple adjustments.

[0057] Specifically, it also includes a transverse movement assembly, which includes a sliding plate 21, a screw rod 23, a transverse movement driving member 22 and a sliding seat 24;

[0058] Furthermore, a transverse driving member 22 is provided on the sliding plate 21 and its driving end is connected to a screw rod 23, the other end of which is rotatably provided on the sliding plate 21; the screw rod 23 is provided through a sliding seat 24 and is threadedly engaged with the sliding seat 24, and the sliding seat 24 is slidably provided on the sliding plate 21;

[0059] Specifically, the transverse driving member 22 is adapted to drive the screw rod 23 to rotate so as to drive the sliding seat 24 to slide on the sliding plate 21;

[0060] Furthermore, the positioning assembly 10 is disposed on the sliding seat 24;

[0061] In the above scheme, the transverse driving member 22 can drive the screw rod 23 to rotate, and the sliding seat 24 is threadedly matched with the screw rod 23, so when the screw rod 23 rotates, it can slide on the sliding plate 21 along the axial direction of the screw rod 23; the positioning component 10 is arranged on the sliding plate 21, so it can drive the positioning component 10 to move, and then drive the crown to be processed to move.

[0062] Specifically, in one embodiment, the transverse driving member 22 may be a rotary motor, and further may be a servo motor.

[0063] For details, see Figure 3 , further comprising a longitudinal movement assembly, the longitudinal movement assembly comprising a stand 31 and a longitudinal movement driving member 32;

[0064] Further, the sliding plate 21 is slidably mounted on the stand 31 in the vertical direction;

[0065] Specifically, the driving end of the longitudinal driving member 32 is connected to the bottom of the sliding plate 21 to drive the sliding plate 21 to move up and down;

[0066] In the above solution, the longitudinal driving member 32 can drive the sliding plate 21 to move up and down, thereby driving the crown to be processed to move up and down; wherein the stand 31 can limit the sliding plate 21, thereby ensuring the stability of its lifting process.

[0067] Furthermore, in some embodiments, a fixing frame 33 is also included, which connects the driving end of the longitudinal driving member 32 and the sliding plate 21; this solution increases the contact surface with the bottom of the sliding plate 21 by further providing a fixing frame 33, thereby making the lifting process of the sliding plate 21 more stable and the force on the bottom more uniform.

[0068] Specifically, in some embodiments, a plurality of sliding seats 24 are provided and are spaced apart along the axial direction of the screw rod 23;

[0069] In the above scheme, in some multi-station processing applications, multiple sliding seats 24 can be set and then equipped with multiple positioning components 10, so that multiple crowns to be processed can be fixed at the same time and multiple crowns can be processed synchronously, effectively improving processing efficiency.

[0070] It is understandable that the denture processing and positioning mechanism provided in this application can be used in conjunction with semi-automatic or fully automatic processing equipment for further processing.

[0071] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application.
