Abstract

The invention relates to the technical field of lathes, in particular to a device for preventing a lathe chuck spanner from being thrown out. The device for preventing the lathe chuck spanner from being thrown out comprises a lathe bed and a sleeve which is arranged on the lathe bed and is provided with a hollow cavity, wherein a first pressing plate and a second pressing plate are arranged in the hollow cavity, the second pressing plate is located above the first pressing plate, a reset spring is arranged between the first pressing plate and the second pressing plate, a first conductive block is arranged on the side, facing the second pressing plate, of the first pressing plate, a second conductive block which is opposite to the first conductive plate is arranged on the second pressing plate, the first conductive block and the second conductive plate are connected into a main circuit of a machine tool in series, and the first pressing plate, and the second pressing plate and the reset spring are all insulating bodies; when the chuck spanner is inserted in the sleeve, the chuck spanner can press the second pressing plate towards the first pressing plate, the first conductive block makes conduct with the second conductive block touch so as to close the main circuit of the machine tool at the moment, then the machine tool operate, and thus the problem that the chuck spanner is thrown out to hurt people is solved.

Description

technical field [0001] The invention relates to the technical field of lathes, in particular to a device for preventing the chuck wrench of a lathe from being thrown out. Background technique [0002] Lathes are commonly used equipment in mechanical processing. According to the safety operating regulations for lathe workers, when the operator does not use the chuck wrench, the chuck wrench is never allowed to stay on the chuck. This point is often overlooked for beginners, and skilled workers occasionally Also can make such mistake, the accident that causes thereby is not uncommon, and existing anti-chuck wrench throws out device complex structure, and cost is higher, and some have also adopted control system and have increased the operation cost of enterprise greatly. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problem that the operator will forget to take off the chuck wrench and start the machi...
