Description

The circular arc camber Work treatment installation

Technical field

The utility model relates to a kind of Work treatment installation, particularly the circular arc camber Work treatment installation.

Background technology

Lathe is the common equipment of processing metal workpiece (or part), the work characteristics of machine tool is: with machine spindle to the work metal workpiece that is arranged in parallel, be fixed on the jig and rotate, be fixed on the cutter on the workbench (workbench is placed in lathe top), about (along the lathe axial direction), front and back (with work metal workpiece vertical direction) move, the outer surface of work metal workpiece is processed.

At present, when adopting the metal works of machine tool processing outer surface curved surface, following 5 kinds of methods are arranged generally:

(1) Artificial Control, its shortcoming are that the machining accuracy of metal works is difficult to control;

(2) mimicking is copied in employing, on original lathe, increases the stencil master of the similar bitting form of a cover, by the copying curved surface.

Its shortcoming is that a kind of curved surface will be made a cover template.Curved surface as needs processing has more than 20 kinds, and the amount of every kind of Machining of Curved Surface is little again, and therefore, its cost is also very big, and the price of 20 cover templates equals a chassis bed expense.

(3) adopt molding cutter, on original lathe, grind the cutter of identical curved surface by the curved surface model, add man-hour, cutter is once finished Machining of Curved Surface.

Its shortcoming is: the curved surface of processing is subjected to the dynamic effect of material, subsequent corrosion, lathe big.The curved surface that only adapts to the minor radius of processing cast iron class; In addition, the low precision of the curved surface roughness of the method processing.

(4) adopt manual imitative type, on original lathe, as the in-process measurement plate, method is by hand imitated type by the curved surface model.

Its shortcoming is: process velocity is slow, efficient is low; The precision of the curved surface roughness of processing is very poor.

(5) adopt numerically controlled lathe to process, still, numerically controlled lathe price height generally is more than 2 times of engine lathe, and manufacturing cost is also improved thereupon.

Summary of the invention

The purpose of this utility model is a kind of cutter arrangement of processing the circular arc camber workpiece of design, can utilize machine tool that the circular arc camber workpiece is accurately processed, and improves the workpiece range of work of machine tool.

For achieving the above object, the technical solution of the utility model is,

The circular arc camber Work treatment installation is arranged on the lathe; Comprise that workbench is fixed on the lathe; Rotating mechanism is fixed in workbench, and it comprises, gear housing is fixed on the workbench; Master gear, pinion are arranged in the gear housing, and both are meshing with each other; Worm and gear is arranged in the gear housing, and the end of worm screw is connected with pinion; Rotation platform is arranged on the gear housing, fixedlys connected with worm gear by connecting axle; Rotary handle is and by connecting axle and master gear fixed connection; Cutter member is fixed in rotation platform, and it comprises that base is fixed in rotation platform; Knife rest is fixed on the base; Knife bar is fixed in the knife rest; Blade is fixed in the leading section of knife bar; Screw rod is arranged in the knife bar, and threaded engagement with it, and its other end is fixed an adjusting nut.

Rotate rotary handle, drive the master gear that connects in the gear-box and rotate, master gear drives pinion and rotates, and pinion drives worm screw and rotates, and the worm gear of worm screw driven rotary platform bottom rotates, and rotation platform is rotated along the horizontal plane direction together.

Under the effect of adjusting nut, control knife bar horizontal plane direction in knife rest is done the straight line adjustment, moves forward and backward along the position of center line of workbench; Blade is installed in the forefront of the knife bar (not marking among the figure) in the knife rest, can change, and the point of a knife of blade is on the position of center line of rotation platform; Adjusting nut is placed in the rear portion of knife rest, and is connected with screw rod between the knife bar, and the rotation adjusting nut makes knife bar move forward and backward along the center line of rotation platform, reaches the purpose that increases or reduce cutter processing radius.

The beneficial effects of the utility model

On enterprise original machine tool basis, do not increase too much fund input, machine tool is accurately processed the circular arc camber workpiece, improves the workpiece range of work of machine tool.
