A lathe with a cooling device

Abstract

The invention discloses a lathe provided with a cooling device. The lathe comprises a rack and turning boxes mounted on the rack; the two turning boxes are symmetrically arranged; three-jaw chucks for clamping turning tools, rotating mechanisms for driving the three-jaw chucks to rotate and sliding mechanisms for driving the turning boxes to slide in the length direction of the rack are arranged on the turning boxes; liquid storage bottles are fixedly mounted on the rack and are located above the turning boxes; the lower end surfaces of the liquid storage bottles are connected with liquid infusion pipes communicating with the liquid storage bottles and air inlet pipes for introducing air into the liquid storage bottles; the liquid infusion pipes are flexible; one end, opposite to the corresponding liquid storage bottle, of each liquid infusion pipe is aligned to a workpiece; an adjuster is fixedly arranged on each liquid infusion pipe and comprises an adjusting casing fixedly arranged on the liquid infusion pipe and a driving wheel for adjusting the area of an inner hole, located at the adjusting casing, of the liquid infusion pipe; and each driving wheel is glidingly connected to the adjusting casing in a positioned manner. The flow of cooling liquids can be adjusted, the workpiece is sufficiently cooled, the machining precision is improved, and the service life of the tools is prolonged.

Description

technical field [0001] The invention relates to a lathe, in particular to a lathe provided with a cooling device. Background technique [0002] At present, the known lathes all have a power system to control a chuck to work. In order to improve work efficiency and reduce the space occupied by the equipment in the work area, there are also two power systems combined on a lathe guide rail for design and processing, which can reduce The number of workpiece clamping and improve processing efficiency. [0003] For example, the application number is CN02231472.5 patent, which discloses a double-head CNC lathe, including a numerical control system, a lathe and a headstock thereof, and two headstocks are arranged on the CNC lathe. During processing, the user first uses the left headstock for cutting, and the right headstock can carry out the work of clamping the workpiece. After the left workpiece is processed, the user immediately starts the right headstock, and uses the same set ...

Problems solved by technology

[0006] In actual processing, the turning tool will process different workpieces, and the amount of water sprayed in the above-mentioned water cooling device is fixed; if the amount of water sprayed is large to ensure that the workpiece can be cooled under any working condition, it will cause waste of water resources; If the amount of water sprayed is small, the workpiece cannot be sufficiently cooled under certain working conditions, which will affect the machining accuracy of the workpiece
