Abstract
The utility model discloses a lathe used for processing a camshaft and provided with an auxiliary bracket. The lathe comprises a lathe body, wherein a lathe guide rail is arranged on the lathe body, the auxiliary bracket is further included, the auxiliary bracket comprises a bracket seat and a self-centering central frame connected to the bracket seat, and the bracket seat is connected in a sliding manner with the lathe guide rail; and the axial line of the self-centering central frame is positioned on the axial lead of the main shaft of the lathe. The lathe provided by the utility model can be used for a centre lathe or a numerically controlled lathe, the self-centering auxiliary bracket for camshaft turning is arranged on the lathe, during processing, the auxiliary bracket is placed on the lathe guide rail in a properly selected position and moves along the lathe guide rail, the bracket seat is locked, a workpiece is placed on the lathe, the self-centering central frame is closed, then the camshaft is processed, stress deformation during camshaft processing can be effectively reduced, and the requirements of external conditions in machining precision can be met.
Description
Technical field
The utility model relates to machine tool field, especially relates to a kind of lathe of machining cam axle.
Background technology
Camshaft is a vitals in the piston-mode motor.The main body of camshaft is a cylindrical barred body identical with cylinder group length, and design has several cams above.Its effect is the unlatching and the closed action of control valve.Though the rotating speed of camshaft is half (rotating speed at two stroke engine convexity wheel shaft is identical with bent axle) of bent axle in four-stroke engine, but its rotating speed is still very high usually, and need bear very big moment of torsion, therefore very high in the requirement aspect intensity and the support in the design to camshaft, camshaft design in the design of engine in occupation of crucial status.At present, most of engine design, particularly high-powered engine all adopt whole forged steel camshaft, and its material adopts medium carbon steel mostly.
According to special instructions for use, be the slender axles of multistage with the design shape of camshaft, its draw ratio can reach 30:1, is typical slender rod type part.And the shape of multistage makes to add man-hour in turning, needs a large amount of grooving cutters that adopt to carry out radial cutting, and workpiece deformation is serious during cutting, and machining condition extremely worsens.
The utility model content
The purpose of this utility model is to provide a kind of simple minimizing camshaft to add the lathe of distortion in man-hour.
The technical solution of the utility model is:
A kind of lathe of band auxiliary bracket of machining cam axle, comprise the body of lathe bed, the body of lathe bed is provided with the lathe guide rail, and it also comprises auxiliary bracket, described auxiliary bracket comprises bearer carrier and the self-centering centre frame that is connected on the bearer carrier, and described bearer carrier and lathe guide rail are slidingly connected; The axis of described self-centering centre frame is positioned on the lathe spindle axial line.
Also be provided with retaining mechanism on the described auxiliary bracket with guide rail locking.
Described bearer carrier is provided with riser, and described self-centering centre frame is connected with a side bolt of riser.
The utility model is used for engine lathe or numerically controlled lathe, the utility model is provided with camshaft turning self-centering auxiliary bracket on lathe, adding man-hour, auxiliary bracket is being placed on the lathe guide rail, moving along the lathe guide rail, select to place in position, and the locking tray seat, workpiece is placed on the lathe self-centering centre frame closure, machining cam axle then can effectively reduce the stress deformation that camshaft adds man-hour, the external condition requirement of satisfying machining accuracy.Machining deformation problem when the utility model has solved camshaft turning, and easy to install; Be provided with a riser in the middle of the bearer carrier, riser is provided with four bolts hole, the self-centering centre frame is installed in the left side or the right side of riser by bolt, the shortest with the distance that makes self-centering centre frame and spindle flange or tail centre as far as possible, when the turning district is between auxiliary bracket and dead center, the self-centering centre frame is installed in the right side of bearer carrier, and when the turning district was between lathe spindle flange and auxiliary bracket, the self-centering centre frame was installed in the left side of bearer carrier.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of auxiliary bracket.
The specific embodiment
As shown in Figure 1, 2, the utility model comprises the body of lathe bed 1 and auxiliary bracket 2, and auxiliary bracket 2 comprises bearer carrier 8 and self-centering centre frame 9.Be provided with a riser 10 in the middle of the bearer carrier 8, riser 10 is provided with four bolts hole, self-centering centre frame 9 is installed in the left side or the right side of riser 10 by bolt, should make the distance of self-centering centre frame and spindle flange or tail centre the shortest according to the difference in turning district during installation.
As shown in Figure 2, the centre frame of auxiliary bracket 2 is provided with three claws, and there is roller 4 end of claw, and three claws stretch out synchronously under the drive of hydraulic cylinder and block shaft-like workpiece 5(such as camshaft during work), shaft-like workpiece 5 rotates under lathe 1 rotating disk drives, and roller 4 also rotates thereupon.The center of circle of the tangent circle of three rollers 4 is positioned at and adds on shaft-like workpiece 5 the center line in man-hour, realizes the self-centering function.Relatively rotating of three carrying rollers 4 also can adopt this area alternate manner commonly used to realize.
In the processing, auxiliary bracket 2 is moved to guide rail 3 precalculated positions, locking then, after workpiece to be processed was put into lathe, three claws entad moved simultaneously under the drive of hydraulic cylinder and clamp shaft-like workpiece 5, begin processing then.After the completion of processing, three claws outwards move simultaneously under the drive of hydraulic cylinder and return, and unclamp shaft-like workpiece 5, and workpiece can take off from lathe.Put into next workpiece to be processed then, proceed processing.
