Description

Technical Field

[0001] The utility model relates to the technical field of denture making, in particular to a fixed base for denture making. Background Art

[0002] Dentures are artificial teeth that are replaced after teeth are lost or extracted in order to restore chewing, aesthetics, pronunciation and other functions. During the denture making process, after the crown, abutment and implant are fixed, the abutment or crown needs to be polished. In the process of denture grinding, a fixed base is needed.

[0021] See also Figure 1-Figure 5 The utility model provides a technical solution: a fixed base for denture production, comprising a workbench 1, a rotating rod 2 is installed on the upper surface of the workbench 1 through a bearing, one end of the rotating rod 2 penetrates and extends to the inside of the workbench 1, an adjusting block 3 is fixedly sleeved on the outer surface of one end of the rotating rod 2, an arc-shaped limiting groove 4 distributed in a ring array is opened on the outer surface of the adjusting block 3, and a toggle groove 5 distributed in a ring array is opened on the outer surface of the adjusting block 3;

[0022] The other end of the rotating rod 2 is provided with an adjusting device, and the adjusting device includes a rotating disk 6 , and the lower surface of the rotating disk 6 is fixedly connected to the other end of the rotating rod 2 .

[0023] Furthermore, a servo motor 61 is fixedly installed on the inner bottom wall of the workbench 1, and the output shaft of the servo motor 61 is fixedly installed with a rotating shaft 62 through a coupling. An arc-shaped limit block 63 is fixedly sleeved on the outer surface of one end of the rotating shaft 62. The outer surface of the arc-shaped limit block 63 contacts the inner wall of one of the arc-shaped limit grooves 4. The arc-shaped limit block 63 limits and fixes the adjustment block 3 by limiting the cooperation with the arc-shaped limit groove 4, thereby limiting and fixing the turntable 6 through the rotating rod 2.

[0024] Furthermore, a mounting plate 64 is fixedly sleeved on the outer surface of the rotating shaft 62, a toggle rod 65 is fixedly connected to the upper surface of the mounting plate 64, and mounting blocks 66 distributed in a circular array are fixedly connected to the upper surface of the rotating disk 6. The rotation of the rotating shaft 62 drives the toggle rod 65 to rotate through the mounting plate 64.

[0025] Furthermore, the two side surfaces of the mounting block 66 contact each other, and the inner walls on both sides of the mounting block 66 are fixedly connected with symmetrically distributed guide rods 67, the inner walls of the guide rods 67 are movably sleeved with a moving block 68, and the outer surfaces of the guide rods 67 are movably sleeved with a return spring 69, and the guide rods 67 play a role in guiding the movement of the moving block 68.

[0026] Furthermore, one end of the return spring 69 is fixedly connected to one side surface of the moving block 68, the other end of the return spring 69 is fixedly connected to one side inner wall of the mounting block 66, the other side surface of the moving block 68 is fixedly connected with a positioning rod 610, and a first support 611 is fixedly installed on the front side of the moving block 68. The return elastic force of the return spring 69 drives the moving block 68 to perform a return movement, and drives the positioning rod 610 to perform a return movement through the moving block 68.

[0027] Furthermore, the inner wall of the first support 611 is hinged with a swing rod 612 through a pin shaft, and one end of the two swing rods 612 is hinged with a second support 613. The front of the second support 613 is fixedly connected with a connecting rod 614, and one end of the connecting rod 614 passes through and extends to the front of the mounting block 66. The connecting rod 614 serves to facilitate the movement of the second support 613.

[0028] Furthermore, one end of the connecting rod 614 is fixedly connected to a pressing block 615, and a slot 616 is provided on the upper surface of the mounting block 66. A fixing seat 617 is movably inserted into the inner wall of the slot 616. The lower surface of the fixing seat 617 contacts the inner bottom wall of the mounting block 66. The two side surfaces of the fixing seat 617 are provided with symmetrically distributed positioning holes 618. The inner wall of the positioning hole 618 is movably inserted into one end of the positioning rod 610. One end of the positioning rod 610 is in a pointed cone shape, so that it produces an interference fit when it is inserted and limited with the positioning hole 618, thereby avoiding the fixing seat 617 from loosening.

[0029] Through this adjustment device, multiple fixing seats 617 can be rotationally adjusted, thereby avoiding the need for workers to repeatedly move positions when grinding dentures of different models, reducing manual labor, and facilitating disassembly and assembly of the fixing seats 617, thereby facilitating cleaning of the fixing seats 617.

[0030] Working principle: Step 1, start the servo motor 61 to drive the rotating shaft 62 to rotate one circle, the rotation of the rotating shaft 62 drives the mounting plate 64 and the arc-shaped limit block 63 to rotate, the rotation of the arc-shaped limit block 63 makes it disengage from the arc-shaped limit groove 4, thereby canceling the limit on the adjustment block 3, and at the same time, the rotation of the mounting plate 64 drives the toggle rod 65 to rotate, and the toggle rod 65 cooperates with the toggle groove 5 to drive the adjustment block 3 to rotate ninety degrees. After the rotation is completed, the arc-shaped limit block 63 contacts the next arc-shaped limit groove 4 again, thereby limiting the rotating rod 2 after the rotation is completed. At this time, the rotating rod 2 drives the mounting block 66 to rotate ninety degrees through the turntable 6, so that the staff can grind the dentures in different fixed seats 617 without moving;

[0031] Step 2, when it is necessary to clean the inside of the fixed seat 617, the pressure block 615 is pressed to drive the second support 613 to move through the connecting rod 614, and the movement of the second support 613 drives the first support 611 to move through the swing rod 612, and the movement of the first support 611 drives the moving block 68 to move through the cooperation of the guide rod 67. At this time, the reset spring 69 is squeezed and contracted, and the moving block 68 drives the positioning rod 610 to move, so that it is separated from the limit of the positioning hole 618, and the fixed seat 617 can be taken out for cleaning. After cleaning, the fixed seat 617 is inserted into the slot 616, and then the pressure block 615 is released. The elastic force of the reset spring 69 drives the moving block 68 to reset and move, and the moving block 68 drives the positioning rod 610 to reset and move, so that one end of it is inserted into the positioning hole 618 to limit and fix the fixed seat 617.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
