A positioning jig for positioning dentures

Abstract

The invention relates to the field of denture processing and repair equipment, and in particular to a positioning fixture for positioning dentures. The bottom of the denture is provided with a positioning hole. The positioning fixture for positioning dentures includes a base, an expansion support device and a telescopic clamping device. ; The expansion support device is installed on the base, which is suitable for inserting into the positioning hole to support the denture; the telescopic clamping device is installed on the base, which is suitable for clamping the outer surface of the denture. The positioning fixture for positioning dentures of the present invention clamps the dentures from multiple directions through the cooperation of the expansion support device and the telescopic clamping device, thereby realizing multi-point positioning and installation of the dentures, and has the advantages of convenient positioning operation and control It has the advantages of low difficulty and high positioning accuracy; the expansion support device supports the denture, avoiding the deformation of the overall shape due to force when the denture is clamped; the use of mechanical devices for clamping also makes the denture fixed better.

Description

technical field [0001] The invention relates to the field of denture processing and repairing equipment, in particular to a positioning fixture for positioning dentures. Background technique [0002] In recent years, with the continuous development of my country's economy and the continuous improvement of people's living standards, oral health problems have become an important factor affecting people's quality of life. Therefore, people pay more and more attention to oral health problems. In particular, the problem that the rate of tooth loss among the middle-aged and elderly people is becoming more and more serious has become increasingly prominent, resulting in a continuous increase in people's demand for dentures. Dentures need to be processed and repaired after one end of use, and in order to increase the comfort of denture users when using dentures, the precision of denture processing and repairs is extremely high. [0003] Among them, for dentures, since the specific ...

Problems solved by technology

[0003] Among them, for dentures, since the specific shape of dentures varies from person to person, dentures have the characteristics of complex curved surfaces, small structural dimensions, and low rigidity, which makes it impossible to use conventional fixtures to position dentures. Therefore, the current Denture processing and refurbishment is mainly carried out under the condition of manual hand-held, but it is difficult to guarantee the processing accuracy, and the work efficiency is also low
