Description

Technical Field

[0001] The utility model relates to the technical field of artificial teeth processing, in particular to a clamping jaw of an artificial teeth cutting machine. Background Art

[0002] Dentures are what people often call "false teeth". Dentures are divided into two types: removable and fixed. Fixed dentures cannot be taken off and put on by patients themselves, while removable dentures can be easily taken off and put on by patients. Removable dentures are connected by transfer bases and implants that fit the mouths of different patients.

[0003] In denture processing, it is usually necessary to use a clamp to clamp the blank firmly before using cutting or carving tools for processing. In traditional technology, fixed mechanical clamps or hydraulic clamps are generally used to clamp the blank.

[0004] The existing method is basically to tighten the Latin on the half-disc clamp by the pulling claw of the robot to further tighten the connection, but the arc-shaped base of the denture is slightly Y-shaped, and the force points are concentrated at the fork connection of the Y-shaped during the mechanical vibration of the processing, and there is no reinforcement mechanism, so the service life is not long. Utility Model Content

[0007] A side guard plate 1 is fixed to one end of the connecting shaft close to the cylinder, a coupling is installed on the output shaft of the driving motor, a side guard plate 2 is fixed to one end of the coupling outside the cylinder, two positioning grooves are provided on the opposite sides of the side guard plate 1 and the side guard plate 2, and a bottom rod is fixed between the lower sides of the side guard plate 1 and the side guard plate 2;

[0008] A Latin is provided on the outer side of the external fixator; a cylinder is provided on the outside of the end of the external fixator away from the Latin, and there is no direct connection between the cylinder and the external fixator; a connecting horizontal plate is provided on the end of the cylinder close to the external fixator, and a flat plate is provided under the connecting horizontal plate, and the flat plate and the connecting horizontal plate form an L shape.

[0009] Furthermore, the opposite sides of the connecting horizontal plate and the flat plate are both provided with sound-proof silicone pads.

[0010] Furthermore, the cylinder is located at the center of the connecting cross plate, and the cylinder axis coincides with the Latin axis.

[0011] Furthermore, an elastic buffer layer is provided on the upper surface of the flat plate.

[0012] Furthermore, the driving motor is a stepping motor, and the stepping motor has forward rotation and reverse rotation.

[0013] Furthermore, the positioning slide groove is higher than the flat plate, a gap is provided between the flat plate and the first side guard plate, and the first side guard plate and the second side guard plate are arranged opposite to each other.

[0014] The advantages of the utility model compared with the prior art are:

[0015] By setting a U-shaped external fixator, and using the side guard plate 1 and the side guard plate 2 in combination with the positioning slide grooves with the guide edges sliding relative to each other, the denture base material can be quickly inserted between the side guard plate 1 and the side guard plate 2, thereby realizing the rapid assembly of the denture base material;

[0016] The driving motor rotates in the left and right directions, driving the side guard plate 1 and the side guard plate 2 to flip, thereby changing the flip of the denture base material between the side guard plate 1 and the side guard plate 2, and changing the cutting angle and position;

[0017] The telescopic movement of the cylinder drives the connecting cross plate to move closer to or away from the side guard plate 1 / side guard plate 2, and then the side guard plate 1 and the side guard plate 2 can be clamped or not clamped to flip the denture base material to a flat surface, so that when cutting, the denture base material can be firmly located between the side guard plate 1, the side guard plate 2 and the connecting cross plate, balancing the stress points and extending the service life.
