Disc type vertical multi-spindle numerical control lathe adopting shaft speed variable principle

Abstract

The invention discloses a disc type vertical multi-spindle numerical control lathe adopting a shaft speed variable principle. The lathe structurally comprises a controller, a machining bin, a fixing base, an equipment base, a servo box, an overhaul door, a control host and a protective door. According to the lathe, when a main shaft mechanism is machined, a punching mechanism is matched with a driving shaft to rotate, and a linkage sleeve part on the inner side of an annular spraying assembly is driven, so that cooling liquid is quickly led out from the inside of an ejector pin, blockage in acooling connecting pipe is intermittently adsorbed and dredged, and finally an arc-shaped spraying column is controlled by the annular spraying assembly to rotate and spray, therefore, the driving shaft, a turning tool shank and a workpiece are uniformly cooled, and local cooling is avoided; and a tool can perform machining under the condition of real-time cooling, and the whole service life is prolonged.

Description

technical field [0001] The invention relates to the field of numerically controlled lathes, in particular to a disk type vertical multi-spindle numerically controlled lathe adopting the principle of variable shaft speed. Background technique [0002] Numerical control is to convert the circuit thinking of computer programming structure into digital technology, and carry out processing control operation through numerical control lathe. With the breakthrough of research and development technology, the current CNC lathes can be equipped with two or more spindles and platforms for processing, thereby improving work efficiency. There are such problems in the use of existing technologies on the market: [0003] Due to the flat design of the side machining spindle used in the existing technology of CNC lathes, if the cooling system pressure is low or there is a slight blockage during cooling, the coolant cannot reach the cutting position, forming a state of partial cooling, and th...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a disk-type vertical multi-spindle CNC lathe using the principle of variable shaft speed to solve the problem that the CNC lathe in the prior art uses a flat design for the side processing spindle. If the pressure of the cooling system is low or there is a slight blockage during cooling, the coolant cannot reach the cutting position, forming a state of partial cooling, and the tool is in a state of long-term high-temperature cutting, which will eventually affect the service life of the tool and the spindle
