Improved numerically controlled lathe

Abstract

The invention discloses an improved numerically controlled lathe structurally comprising an adsorption plate, an operation panel, a slide rail, a lathe body, a movable slide block, a protective device, a switch door, a fixed seat, an air blowing device, a tool rest and a slide way. After improvement, the air blowing device is operated by a controller, and the air is conveyed into a connecting ringthrough a guide pipe, so that an air blowing port uniformly blows the air out, metal scraps adsorbed on the surface of a tool or a machined part are blown onto the adsorption plate, and the tool is prevented from being interfered with by the metal scraps in the machining process of the part; when the lathe opens the switch door after processing the part, the switch door slides to left and right sides due to inertia; and when the switch door touches a chucking board, the switch door is magnetically and fixedly adsorbed on the chucking board through a magnetic adsorption ball under the magneticaction, and the switch door is protected through cooperation of a protective cover and a buffering bullet piece, such that the inner side of the switch door is avoided from deforming, the switch doorcan be normally closed, and the sealed effect of protecting the switch door is achieved.

Description

technical field [0001] The invention relates to the field of numerically controlled lathes, in particular to an improved numerically controlled lathe. Background technique [0002] With the rapid development of social economy, CNC lathes are one of the most widely used CNC machine tools at present. CNC lathes are generally used in production workshops. CNC machine tools automatically process the processed parts according to the pre-programmed processing programs. CNC machine tools increase the processing speed and accuracy of workpieces and increase productivity. When the CNC lathe is processing, it needs to be improved: [0003] 1. When the CNC lathe is performing processing operations, the metal debris generated is easy to accumulate and adsorb on the surface of the tool or the processed parts, causing the tool to be interfered by metal debris during the processing of the parts, making the surface of the processed parts unsuitable for use. Requirements, greatly reducing ...

AI Technical Summary

Problems solved by technology

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an improved CNC lathe to solve the problem that when the CNC lathe is performing processing operations, the metal debris generated is easy to accumulate and adsorb on the surface of the tool or the machined parts, causing the tool to be broken. Interference with metal debris during the processing of the parts makes the surface of the processed parts not meet the requirements for use, which greatly reduces the quality of the processed parts. When the switch door is opened after the CNC lathe is processed, the switch door and the car body will collide with each other due to inertia , causing the opening and closing door to rebound and close again, causing deformation on the inside of the opening and closing door, making the opening and closing door unable to close normally, and affecting the sealing effect of the opening and closing door
