Description

High-precision high-finish forming and carving device and method for tooth occlusal pad

Technical Field

The invention relates to the technical field of tooth occlusion pad processing, in particular to a high-precision high-finish forming and carving device and method for a tooth occlusion pad.

Background

In tooth filling, a machine is generally used for grinding teeth, and at the moment, a tooth occlusion pad is needed so as to separately position upper teeth and lower teeth of a person, and further, a doctor can conveniently grind the teeth. The structure of the tooth occlusion pad is shown in figures 1-3, and comprises an occlusion pad body (46), an upper groove (47) and a lower groove (48) which are respectively arranged at the upper end and the lower end of the occlusion pad body (46), when in use, the upper teeth bite at the groove bottom of the upper groove (47), and the lower teeth bite at the groove bottom of the lower groove (48). Wherein, the upper groove (47) and the lower groove (48) are processed by a carving machine, and the processing technology is as follows: a worker firstly places a blank on a tool table of a carving machine, then fixes the blank on the tool table through a pressing mechanism on the tool table, and then a carving knife on the carving machine carves along the length direction of the blank so as to machine an upper groove (47); the blank is turned 180 degrees, and the lower groove (48) can be processed by repeating the operations, so that the processing of the tooth occluding cushion is finally realized.

However, in the actual production in a production plant, a number of problems arise: 1. in addition, the pressing plate applies downward pressure to the blank, the carving direction of the carving knife is in the horizontal direction, the blank slides on the tool table, the machined upper groove (47) and the machined lower groove (48) are asymmetric, the upper groove (47) and the lower groove (48) are technically required to be vertically symmetric, and therefore the machining precision of the tooth occlusion pad is reduced. 2. In the process of carving the blank by the carving knife, the cooling liquid can only be sprayed on the top surface of the blank, so that the upper half part of the blank is cooled, the lower half part of the blank cannot be sprayed on the cooling liquid, the bottom surface of the blank is heated and deformed, the upper end surface and the lower end surface of the produced tooth occlusion pad are non-planar, the upper end surface and the lower end surface of the tooth occlusion pad are technically required to be planar, and the processing precision of the tooth occlusion pad is further reduced. 3. The bottom surface and two side surfaces of the groove are ground after the upper groove (47) and the lower groove (48) are machined by the engraving machine so as to remove burrs remained in the groove. 4. Because the groove bottoms of the upper groove (47) and the lower groove (48) are directly contacted with teeth, in order to prevent the teeth from being damaged, the groove bottoms of the grooves are technically required to have higher smoothness, but the grooves can only be polished by working experience during manual polishing, and although the smoothness of the groove bottoms can be improved, the smoothness required in the market can not be met. Therefore, an engraving device for improving the smoothness of the groove bottom, improving the machining precision of the tooth occlusion pad, reducing the labor intensity of workers and improving the production efficiency of the tooth occlusion pad is needed.
