Double-cooking device of full-automatic artificial tooth engraving and milling machine

Abstract

The invention belongs to the technical field of the artificial tooth processing of the dental restoration industry, and particularly relates to a double-cooking device of full-automatic artificial tooth engraving and milling machine, which comprises an electric spindle, and an inner clamping sleeve and an outer clamping sleeve which are used for fixing the electric spindle, wherein a joint and a support are respectively arranged on the side wall of the inner clamping sleeve, the joint is respectively connected with an air blowpipe and a cooling water pipe, a dust suction pipe is installed on the support, an air pipe is arranged at the top end of the dust suction pipe, a filter screen is arranged below the electric spindle, a water tank is arranged at the bottom of the filter screen, and is connected with a water circulating pump, a water pipe is arranged on the water circulating pump, the rear end of the water pipe is connected with the cooling water pipe. The invention has the beneficial effects that: the double-cooking device has a simple structure, is convenient to use, and can select the appropriate cooling mode according to different processing materials, and the working quality and efficiency are improved.

Description

technical field [0001] The invention relates to a double cooling device of a fully automatic denture engraving and milling machine, which belongs to the technical field of denture processing in the oral restoration industry. Background technique [0002] At present, the cooling method used by automatic denture engraving and milling machines to process dentures is a single cooling method, that is, a single liquid cooling method or a gas cooling method. [0003] When the liquid cooling method is adopted, the zirconia cake that was initially sintered during the processing is equivalent to being soaked in the cooling liquid. When using zirconia cakes, the properties of zirconia materials change, such as changes in hardness and shrinkage ratio, etc. Changes in hardness lead to faster tool loss and changes in shrinkage ratio, resulting in a large increase in the waste of dentures after sintering. [0004] When gas cooling is used, the air compressor is usually used to blow the ga...

Problems solved by technology

[0003] When the liquid cooling method is adopted, the zirconia cake that was initially sintered during the processing is equivalent to being soaked in the cooling liquid. When using zirconia cakes, the properties of zirconia materials change, such as changes in hardness and shrinkage ratio, etc. Changes in hardness lead to faster tool loss and changes in shrinkage ratio, resulting in a large increase in the waste of dentures after sintering

[0004] When gas cooling is used, the air compressor is usually used to blow the gas to the tool installed on the electric spindle for cooling. The high-speed electric spindle generates a lot of heat during milling, and the heat cannot be effectively dissipated. Processing paraffin cakes When it is used, the cake will be softened or deformed, which will cause the high-speed electric spindle speed of the engraving machine to be milled and cannot be increased, resulting in low processing efficiency.
