Problems solved by technology

[0002] With the rapid development of high-speed, high-precision, and long-stroke machining application technology, people have put forward higher requirements for the machining accuracy and stability of machine tools and the complexity of workpieces. Machine tool parts are one of the main factors affecting machining accuracy. The accuracy of the screw is the most important thing. The better the accuracy of the screw, the better the machining effect of the machine tool. How to reduce the deformation of the screw has become a problem that needs to be overcome in the machine tool industry, and the screw needs high-speed rotation. High-speed thermal deformation will affect the accuracy of the screw, and increase the reverse gap, which needs further improvement

Embodiment Construction

[0018] The present invention will be further described below through specific embodiments.

[0019] refer to Figure 1 to Figure 2 As shown, a cooling system for a screw rod includes a screw rod 1 , a cooling device 3 , a rotary joint 2 , an output pipeline 4 and an input pipeline 5 .

[0020] The screw rod 1 includes a screw rod body 11 and a spiral cooling tube 12 .

[0021] The spiral cooling pipe 12 is set in the screw body 11 by casting. Specifically, the spiral cooling pipe 12 is made of high-temperature-resistant copper tube. When the screw rod 1 is cast, the high-temperature-resistant spiral cooling pipe 12 is put into the mold, and then Pour molten steel to form a semi-finished product, and then process threads on the outer wall of the semi-finished product to form a screw 1. The spiral cooling tube 12 and the screw body 11 are cast in one casting process. The preparation process is simple, and the spiral cooling tube 12 will not be damaged by wire The high-speed ro...

Abstract

The invention discloses a lead screw and a cooling system thereof. The lead screw comprise a lead screw body, a spiral cooling pipe, a cooling device and two rotary joints, wherein the spiral coolingpipe is arranged in the lead screw body and is provided with a spiral extension section; the cooling device is provided with an output pipeline connected with one end of the spiral cooling pipe through a rotary joint and an input pipeline connected with the other end of the spiral cooling pipe through the rotary joint; the cooling device enables cooling liquid to circularly flow in the spiral cooling pipe and cools the cooling liquid. Heat generated by high-speed rotation of the lead screw body is taken away through continuous circulating backflow of the cooling liquid between the cooling device and the spiral cooling pipe, so that the problem that thermal deformation of the lead screw influences the accuracy of the lead screw due to high-speed rotation is prevented.
