Oral prosthesis machining tool

Abstract

The invention relates to a device for manufacturing a dental crown, in particular to a machining tool. An oral prosthesis machining tool of the invention comprises a tool framework; three translation axes in the transverse, longitudinal and vertical three-dimension direction are arranged on the tool framework; and one side of the transverse translation axis is provided with a workpiece positioning device which is connected with the tool framework through a flexible connector and can slide along the transverse translation axis. The machining tool of the invention has the advantages of simple structure, easy control and operation, high efficiency, high precision and good economical efficiency, can machine metals and machine ceramics with performance closer to that of dental materials by introducing an automatic industrial production system, and meanwhile can establish an interactive network between a central work station and substations by using network technology to implement long-distance design and manufacture and wearing of the prosthesis so as to reduce the indirect expense of wearing and realize resource sharing; therefore, the oral prosthesis machining tool is easy to popularize and use in the market, and has broad industrialized prospect.

Description

technical field [0001] The invention relates to a device for manufacturing dental crowns, in particular to a processing machine tool. Background technique [0002] At present, traditional hand-made restorations are generally used in oral restoration in my country, mainly using methods such as engraving, wax-type, lost-wax casting, and porcelain-fried dentures. After wearing it, you need to go through several follow-up consultations before you can get used to it, which undoubtedly prolongs the patient's pain and treatment time. Moreover, during the fabrication of the prosthesis, the patient needs to wear a temporary prosthesis, which increases the cost of treatment. And the quality of the tooth-shaped outer crown after the repair depends entirely on the doctor's personal technical level, and the tooth-shaped outer crown shape is difficult to reach the general tooth-shaped outer crown shape of people's teeth, which makes the patient feel uncomfortable after the tooth is repair...

Problems solved by technology

However, the existing dual-axis grinding mechanism of the tooth cover processing machine tool has the following defects: the rotational movement of the main shaft is not isolated from the axial movement, and when the main shaft rotates under the drive of the gear shaft, it will drive the main shaft to move axially , so that there is a deviation in the axial movement, which affects the machining accuracy; in order to eliminate this effect, it is necessary to control the stepper motor in the control software of the tooth cover processing to compensate the axial movement, which also complicates the control software of the tooth cover processing machine tool; The axial movement is guided by the gear shaft, and the guiding accuracy is low, which affects the machining accuracy
