Abstract

The invention provides a cooling device for a motor of an engraving machine, and relates to an engraving machine. The cooling device is provided with a motor, the housing of the motor is provided with a cooling mechanism, and the cooling mechanism is a cooling liquid cooling mechanism in the housing of the motor, a spiral cooling liquid pipe cooling mechanism on the periphery of the housing of the motor or a cooling liquid outer cover cooling mechanism on the periphery of the housing of the motor. A cavity is arranged in the cooling liquid cooling mechanism in the housing of the motor, and the cavity is provided with a cooling liquid inlet and a cooling liquid outlet; the spiral cooling liquid pipe of the spiral cooling liquid pipe cooling mechanism on the periphery of the housing of the motor clings to the periphery of the housing of the motor; the cooling liquid outer cover of the cooling liquid outer cover cooling mechanism on the periphery of the housing of the motor sleeves the periphery of the housing of the motor; the cooling liquid outer cover is provided with a cooling liquid inlet and a cooling liquid outlet, the cooling liquid inlet is connected with a cooling liquid outlet of a cooling liquid source, the cooling liquid outlet is connected with a cooling liquid inlet of the cooling liquid source, and a sealing ring can be arranged between the cooling liquid outer cover and the housing of the motor.

Description

technical field [0001] The invention relates to an engraving machine, in particular to an engraving machine motor cooling device. Background technique [0002] Existing engraving machines, such as jade engraving machines, usually adopt the working method of belt transmission to the flexible shaft and then to the handle, while the cooling of the motor is carried out by the fan installed at the tail of the motor; in addition, the chuck of the engraving machine usually uses The main disadvantages of the three-lobe structure are: [0003] 1. The noise generated during belt transmission is large, causing noise pollution to the surrounding environment. [0004] 2. Belts and flexible shafts have a short lifespan and are often replaced. The procedure for replacing the flexible shaft is cumbersome and time-consuming. [0005] 3. Large size, high quality, poor portability, and occupying space. [0006] 4. When working, the engraving machine must be hoisted to work, and the bending ...
