Protective device for lathe

Abstract

The invention discloses a protective device for a lathe. The protective device structurally comprises rack bodies, connecting clamping teeth and a telescopic protective cover. The rack bodies and thecorresponding connecting clamping teeth are of an integrated structure, the connecting clamping teeth are uniformly arranged at one end of each rack body from top to bottom, and the rack bodies are engaged with the telescopic protective cover through the corresponding connecting clamping teeth in a penetrating manner. The telescopic protective cover comprises an assembling head inner groove, a telescopic protective body, sliding groove baffles, springs, telescopic clamping heads, telescopic sliding grooves, protective body sliding grooves, first clamping teeth, a protective cover assembly head, a first gear, a first shaft rod, a protective ejector rod, a second shaft rod, a second gear, a shaft rod assembly plate, a third gear and second clamping teeth. When the device is used, the unfolding state of the device is maintained through the spring structure on the device, and the machining splashing risk caused by the fact that a user forgets to open the protective cover can be lowered; and by arranging various gear mechanisms on the device, the device can be locked in the extending and contracting state in the descent protection use of the device, the shrinkage caused by the error contact is prevented, and the use safety of the device is protected.

Description

technical field [0001] The invention is a lathe protective device, which belongs to the field of lathe protective devices. Background technique [0002] The lathe protection device, that is, the device that can protect the lathe during use, can better prevent the flying chips of the lathe from causing harm to the staff. [0003] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Drill bits, reamers, reamers, screw taps, dies and knurling tools can also be used on lathes for corresponding processing, also known as machine tools, workers who use lathes are called lathes, and lathes are considered to be all equipment in the machining industry. working machine. Lathes are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces, mainly cylinders, and the main movement mode is that the turning tool moves and the workpiece does not move. It is the most widely used type of machine tool in machinery manufacturi...

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a lathe protection device to solve the problem that when the prior art is used, the protection mainly consists of flipping and stretching. For the flipping type, it is easy to cause damage to the fixed part of the protection device due to flipping. The telescopic protective cover is easy to shrink the protective cover due to accidental touch after the protection is lowered, causing collision between the workpiece or the cutter head and the protective cover, causing danger and inconvenience.
