Embodiment Construction

[0014] The present invention is described below in conjunction with accompanying drawing.

[0015] attached Figure 1-3 It is a new type of chuck protection device according to the present invention, which includes a sleeve body 1 and an upper cover 2; the sleeve body 1 is cylindrical, and on the rear end surface of the sleeve body 1, there are protrusions extending radially outward. Disk 5; a plurality of fixing holes 6 are evenly distributed on the convex disk 5; the sleeve body 1 is overcoated on the chuck, and fixed on the machine tool through the fixing holes 6 on the convex disk 5; the sleeve body 1 The front end of the sleeve body 1 is axially cut with a semi-annular groove 3; the semi-annular groove 3 is located directly above the sleeve body 1, and the length of the semi-annular groove 3 is longer than that on the chuck. The distance from the wrench hole to the clamping workpiece end; the upper cover 2 is matched with the semi-circular groove 3, and one end of the up...

Abstract

The invention discloses a novel chuck protecting device comprising a sleeve body and an upper cover. The sleeve body is of a cylinder shape, and the rear face of the sleeve body extends outwards radically to form a convex plate. A plurality of fixing holes are evenly reserved in the convex plate, and the sleeve body is sleeved outside the chuck and is fixed on a machine tool through the fixing holes in the convex plate. A semi-circle groove is axially reserved, along the center of the sleeve body, at the front end of the sleeve body by means of cutting. The semi-circle groove is right above the sleeve body, and the length of the semi-circle groove is greater than the distance from a spanner hole of the chuck to the end of a clamped workpiece. The upper cover made of transparent organic glass matches with the semi-circle groove, and one end of the upper cover is connected with one end of the semi-circle groove through a hinge. With the novel chuck protecting device, involving of outside foreign materials is prevented when the chuck is in high-speed operation, normal operation of the machine tool is guaranteed, service life of the chuck is prolonged, fixing and demounting of the workpiece become convenient, efficiency of processing and producing is improved, and labor intensity of an operator is lowered.

Description

technical field [0001] The invention relates to a protection device, in particular to a protection device installed on a chuck of a horizontal lathe, belonging to the field of lathe auxiliary accessories. Background technique [0002] When a workpiece is processed on a lathe, the chuck that holds the workpiece rotates at high speed along with the spindle. The chuck occupies a relatively large space, and it is easy to twist the thread-like objects and other sundries next to the machine tool onto the chuck or even onto the workpiece, which not only affects the normal processing of the workpiece, but may also break the workpiece and waste a lot of materials. . In addition, if the staff in the production workshop accidentally touch the high-speed rotating chuck, it will also cause personal safety accidents. For this reason, most machine tools are fitted with an arched guard that fits directly over the chuck and wraps the axial length of the chuck within the guard. The protect...
