Electronic hand wheel with good heat dissipation performance

Abstract

The invention discloses an electronic hand wheel with good heat dissipation performance. The electronic hand wheel comprises an electronic hand wheel body, the surface of the electronic hand wheel body comprises a display screen and two switch keys, the display screen is located above the switch keys, one switch key is located on the left side of the other switch key, the surface of each switch key comprises a pulse generator, an indication post, a photoelectric encoder and an index dial, a storage battery is fixedly connected to the bottom of an inner cavity of the electronic hand wheel body,a fixing frame is fixedly connected to the top of the inner cavity of the electronic hand wheel body, and a suction fan is fixedly connected to the bottom of the fixing frame. By means of the cooperation of the electronic hand wheel body, the display screen, the two switch keys, the pulse generator, the indication post, the photoelectric encoder, the index dial, the storage battery, the fixing frame, the suction fan and a temperature sensor, the problems that heat dissipation performance is poor, and the electronic hand wheel is likely to be damaged or control is invalid since the internal temperature is too high are solved.

Description

technical field [0001] The invention relates to the technical field of CNC machine tool accessories, in particular to an electronic handwheel with good heat dissipation performance. Background technique [0002] Electronic handwheel is a necessary accessory of CNC machine tools. It needs to be adjusted during operation to achieve precise positioning. However, the existing electronic handwheels on the market have poor heat dissipation performance. When used for a long time , It is often easy to cause damage to the electronic handwheel or control failure due to excessive internal temperature. Since the price of the electronic handwheel is relatively expensive, if the temperature is too high and the use is inflexible, it will reduce work efficiency and affect production. Contents of the invention [0003] The purpose of the present invention is to provide an electronic handwheel with good heat dissipation performance, which has the advantage of good heat dissipation performan...
