Cooling system for dental milling machine

Abstract

The invention discloses a cooling system for a dental milling machine. The cooling system comprises an oil tank, an oil returning chute, an oil pump and an oil pipe. The oil returning chute is closely attached to the inner wall of the front side of a shell of the dental milling machine and used for collecting cooling liquid flowing from the inner wall of the front side of the shell. The oil pump is connected with the oil tank and the oil returning chute through the oil pipe and used for conveying the cooling liquid in the oil tank and the oil returning chute to the position above a workbench of the dental milling machine to cool a cutter. The oil returning chute is used for collecting the cooling liquid splashed to the shell, under the action of the oil pump, the cooling liquid in the oil returning chute is pumped back into the oil tank, the loss of cooling liquid is avoided, it is guaranteed that the cooling liquid can be reused for a long term, the problem that the shell is contaminated and corroded due to the fact that the cooling liquid is accumulated on the bottom of the dental milling machine for a long term is solved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a dental milling machine cooling system. Background technique [0002] Dental milling machine is a kind of CNC milling machine used for processing dentures. It can process dentures with irregular curved surfaces through the cooperative movement of its spindle and worktable. It can realize the automatic mass production of dentures, improve the processing efficiency of dentures, and reduce production costs. , with the advancement of science and technology, dental milling machines are gradually developing towards high precision and miniaturization. At present, dental milling machines generally use water cooling to cool the processing tools. Most of the coolant is guided by the return groove on the workbench. Returned to the oil tank, but part of the coolant splashed on the shell of the dental milling machine due to impact, and flowed to the bottom of the dental milling machine along the inner wall of the shell, not only causing th...

Problems solved by technology

[0003] In view of this, the object of the present invention is to provide a cooling system for dental milling machines, which uses an oil return tank to collect the coolant splashed onto the casing, and then pumps the coolant in the oil return tank back into the oil tank under the action of an oil pump to avoid The loss of coolant ensures long-term recycling, and at the same time solves the problem of contamination and corrosion of the shell caused by the long-term accumulation of coolant at the bottom of the dental milling machine, prolonging the service life
