Problems solved by technology

At present, there is no tooth wear instrument in China for reference. The relative displacement of the upper and lower teeth of similar foreign instruments is realized by electric circuits controlling the motor, while the occlusal action of the upper and lower teeth is driven by two motors. To achieve this, the motor is required to have positive and negative rotation during work, and its design scheme is complicated, the production cost is high, and the operation and control are inconvenient, so it is not suitable for implementation

Embodiment Construction

[0010] Referring to the accompanying drawings, the tooth wear testing machine of the present invention includes two major parts, a mechanical action device and an electrical device. The mechanical action device is mainly composed of frame table 18, crossbeam 3, cam transmission mechanism and six groups of tooth wear test units 1 arranged in parallel on the frame table 18. The crossbeam 3 reciprocates up and down under the action of the cam drive mechanism through the cam drive frame 17 and the guide rods arranged on both sides of the frame platform 18 frames. In order to achieve the reciprocating action of the crossbeam, the present invention considers the use of a cam transmission mechanism, which is located in the middle of the frame table 18, as shown in Figure 3, it has a drive frame 17 and is connected to the main shaft of the motor 19 through the transmission chain 16. The sprocket 11 is respectively equipped with a pair of cam 15 and jack block 14 for jacking up the bea...

Abstract

This invention relates to one tooth friction test machine through human tooth analogue operation to test human tooth materials and stuff property, which comprises one pair of tooth friction test unit frames set with one piece of protruding wheels for reverse beams, wherein the test unit comprises one pair of contact upper and down tooth chewing analogue structure fixed with one inclination block and one movable block on inclination and one mobile spring reset part; the upper tooth analogue structure comprises one piece of T shape cover cylinder on beam fixed with analogue long tooth and match block.

Description

technical field [0001] The content of the present invention belongs to the technical field of material physical and chemical property testing devices, and relates to a test device for stomatology, in particular to a tooth wear testing machine that can test the performance of artificial tooth materials and tooth fillings by simulating the occlusal action of human teeth. Background technique [0002] The tooth abrasion testing machine is an instrument that simulates the occlusal action of human teeth, that is, the action of chewing food, to test the performance of artificial tooth materials and dental fillings, and to make scientific judgments on their wear procedures. According to the applicant's search, a foreign paper "somulator forthermol and mechanical loading on teeth" once proposed a tooth simulation device. This clock simulation device is driven by air pressure. Filling materials and teeth simulators for simulating occlusion are quite complex in structure. [0003] Th...
