Fixing tool for false tooth processing

Abstract

The utility model relates to the technical field of false tooth machining, and discloses a false tooth machining fixing tool which comprises a barrel-shaped frame, a guide rail, a sliding block, a bending plate, an optical shaft, a clamping plate, a spring, a supporting block and a cam bearing. In the using process, under driving of external force, the four sliding blocks can correspond to the four guide rail sliding blocks correspondingly, and then the four bending plates are driven to be close to or away from one another. And then under the elastic action of the four springs, the four polished shafts can drive the four clamping plates to be close to or away from each other. When the four clamping plates draw close to each other and abut against the false tooth placed on the top surface of the second circular plate, the four springs can be compressed. Therefore, elastic force is generated to clamp and fix the false tooth. Moreover, along with the increase of the deformation quantity of the four springs, the clamping force on the false tooth can be gradually improved. Compared with the mode that the false tooth is directly subjected to clamping force from a plurality of electric push rods, the clamping force can be conveniently controlled, and the clamping force can be linearly changed from small to large, so that the surface of the false tooth is prevented from being deformed or damaged.

[0037] A fixing tooling for denture processing provided by an embodiment of the present disclosure includes a cylindrical frame 1, guide rails 2, sliders 3, bending plates 4, optical axes 5, clamping plates 6, springs 7, support blocks 8, and cam bearings 9. The cylindrical frame 1 includes a first circular plate 01 and a second circular plate 02 distributed on the same center line. Along the height direction of the cylindrical frame 1, the second circular plate 02 is located above the first circular plate 01, and the two are respectively used to support and install other components of the device. Four guide rails 2 are uniformly installed on the top surface of the first circular plate 01 along the radial direction of the cylindrical frame 1. The straight lines where two adjacent guide rails 2 are located are perpendicular to each other, and the four guide rails 2 are distributed at intervals of 90° on the top surface of the first circular plate 01. Four sliders 3 are respectively slidably installed on the four guide rails 2 and jointly play a role of guiding and supporting. Four bending plates 4 are respectively installed on the four sliders 3 and are all movably passed through the second circular plate 02. The second includes four strip-shaped holes opened along its radial direction, and the four strip-shaped holes are respectively used to pass through the four bending plates 4. Four optical axes 5 are respectively slidably passed through the four bending plates 4 along the radial direction of the cylindrical frame 1. The axes of two adjacent optical axes 5 are perpendicular to each other and are respectively used to support and install the clamping plates 6. Along the height direction of the cylindrical frame 1, they are all located above the second circular plate 02 so that the four clamping plates 6 can clamp the denture placed on the top surface of the second circular plate 02. The clamping plates 6 are respectively installed at one end where the plurality of optical axes 5 are close to each other and are all used to abut against the denture placed on the top surface of the second circular plate 02. Springs 7 are respectively sleeved on each optical axis 5 and are respectively located between the upper bending plates 4 and the clamping plates 6, and are all used to provide elastic force. Four support blocks 8 are respectively installed at one end where the four optical axes 5 are far from each other and are all used to play a role of limiting to prevent the four optical axes 5 from falling off the four bending plates 4.

Among them, the plurality of sliders 3 can be controlled to respectively slide relative to the plurality of guide rails 3 to drive the plurality of bending plates 4 to approach or move away from each other.

[0038] During the use process, under the drive of an external force, the four sliders 3 can respectively slide relative to the four guide rails 2, and then drive the four bending plates 4 to approach or move away from each other. Then, under the elastic force of the four springs 7, the four optical axes 5 can drive the four clamping plates 6 to approach or move away from each other. When the four clamping plates 6 approach each other and abut against the denture placed on the top surface of the second circular plate 02, the four springs 7 can be compressed. Thereby generating an elastic force to clamp and fix the denture. And, as the deformation amount of the four springs 7 increases, the clamping force on the denture can be gradually increased. Compared with the denture directly receiving the clamping force from a plurality of electric push rods, it is convenient to control the clamping force and can make the clamping force change linearly from small to large, thereby avoiding deformation or damage to the surface of the denture.

By using one power source, the four clamping plates 6 can be driven to move simultaneously, and finally the clamping and fixing of the denture can be realized, which can play a role in cost saving.

[0043] Optionally, in combination with Figures 1 to 3 As shown, it further includes a rocker arm 13, a round rod 14 and an electric telescopic rod 15.
