Abstract

The invention relates to the technical field of electric appliances for numerically controlled lathes, and discloses a fuse for a numerically controlled lathe. The fuse comprises a fuse shell, first metal sheets are connected to inner side ends of a conducting wire, a rotating shaft is connected between the two first metal sheets, an insulating porcelain cylinder is connected to an outer side faceof the rotating shaft, second metal sheets are connected to upper ends of the first metal sheets, the second metal sheets are connected with a fusing connector, the fusing connector is connected witha fuse wire, a rotating frame is arranged at an upper end of the fuse wire, and a manual rotary table is connected directly above the rotating frame. By means of the cooperative transmission of an inner convex arc-shaped groove in the manual rotary table and a concave arc-shaped groove at the outside of the rotating frame, the rotating frame drives the insulating porcelain cylinder to rotate on the rotating shaft, the second metal sheets at both ends of the fuse shell start to deviate from the fusing connector, when the next fusing connector is in contact with the second metal sheets, the next fuse wire has been connected in series in a circuit of the fuse, and this structure solves the problem that the existing fuse component is complicated and difficult to replace.

Description

technical field

[0001] The invention relates to the technical field of electrical appliances for numerically controlled lathes, in particular to a fuse for numerically controlled lathes. Background technique

[0002] CNC lathe, also known as CNC lathe, is a machine tool that is controlled by computer numbers. It is currently the most widely used machine tool in China. It is mainly used for cutting the inner and outer cylindrical surfaces of shaft parts or disk parts, the inner and outer conical surfaces of arbitrary cone angles, the complex rotary inner and outer curved surfaces, cylinders, and conical threads, etc., and can perform grooving, drilling, reaming, and reaming. Holes and borings etc. The CNC machine tool automatically processes the processed parts according to the pre-programmed processing program.

[0003] The electrical control system of the CNC lathe is mainly composed of a numerical control device (CNC), a servo system, a machine tool strong current contro...
