Motorized spindle adopting clamp cooling

Abstract

The invention discloses a motorized spindle adopting clamp cooling. The motorized spindle comprises a clamp and a motorized spindle body; the clamp is of a hollow structure, and a machine body portionof the motorized spindle body is fixedly inserted into the clamp; the surface of the clamp is provided with an air inlet and an air outlet, the interior of the clamp is provided with an air cooling channel, the air cooling channel surrounds the interior of the clamp by a circle, and the two ends of the air cooling channel communicates with the air inlet and the air outlet correspondingly; and theouter surface of the clamp is further uniformly provided with a plurality of heat dissipation ribs. According to the motorized spindle, the cooling effect of the motorized spindle is greatly improvedthrough synergistic action of the air cooling channel and the heat dissipation ribs, meanwhile, the gas cooling mode is adopted, compared with water cooling, cooling circulation is achieved more conveniently, the degree of cleanliness is higher, sewage leakage, drainage and pollution problems in the cooling process are not generated, influence on the environment of the production site is smaller,and the motorized spindle can adapt to a production workshop high in degree of cleanliness; and through reasonable structure design, the clamp and the motorized spindle body are convenient to installand separate, and the purposes of convenient maintenance and replacement are achieved.

Description

technical field [0001] The invention relates to the field of electric spindles, in particular to an electric spindle cooling with clamps. Background technique [0002] The electric spindle is one of the most important core components of the CNC engraving and milling machine. It is the core component of the engraving, milling and grinding of the CNC engraving and milling machine. It is mainly used in the manufacture of electronic parts, small precision molds, hardware products, furniture manufacturing, etc. industry. [0003] With the development of the industry, the requirements for the weight and cooling method of the spindle are gradually increasing, and the processing and application of small electric spindles are becoming more and more extensive. The electric spindle mainly adopts traditional water cooling, and needs to be equipped with peripheral equipment such as a chiller, which has the disadvantages of large footprint and high cost. At present, some water-cooling s...

AI Technical Summary

Problems solved by technology

Although this technical solution can reduce the equipment of the chiller, the cooling effect of the water-passing method is limited. Due to the limitation of the structure of the clamp itself, the volume of the water-cooling channel is always smaller than that of the entire clamp. The slender water-cooling channel has a small heat dissipation surface area, and the heat can only be taken away by cold water, and it is difficult to pass through the wall thickness of the clamp to dissipate naturally. For the electric spindle that needs to rotate frequently and continuously output large heat in the working condition , the cooling efficiency is limited

In addition, water cooling is also prone to problems such as dripping and discharge of sewage, which affects the working environment of the production site, and is not suitable for high-cleanliness production workshops

[0004] The traditional water cooling scheme can no longer meet the development needs of the current electric spindle
