Abstract
The utility model discloses a suspension type central auxiliary support for a camshaft. The suspension type central auxiliary support comprises a tray with a self-aligning center frame and a beam transversely arranged between two supporting frames, wherein the tray is positioned on the lower part of the beam; and the tray is detachably connected with the beam. The suspension type central auxiliary support can be used for conveniently turning the whole long and thin camshaft at one time.
Description
Technical field
The utility model relates to machine tool field, and especially a kind of lathe of machining cam axle is used auxiliary.
Background technology
Camshaft is a vitals in the piston-mode motor, and the main body of camshaft is a cylindrical barred body identical with cylinder length, is designed with several cams above.Its effect is the unlatching and the closed action of control valve.Therefore, the design and processing and manufacturing in, to camshaft in intensity and the requirement aspect processing very high.When camshaft is slender axles, and utilize grooving cutter to carry out turning to add man-hour, workpiece easy deformation, machining condition extreme difference.
In patent ZL201120032478.4, disclose " a kind of lathe of band auxiliary bracket of machining cam axle ", the turning processing to elongated type of camshaft provides a kind of auxiliary bracket; Auxiliary bracket comprises bearer carrier and self-centering centre frame, because bearer carrier is arranged on the guide rail, cutter is when feed; Can not the machining cam axle omnidistance; Can only process half length camshaft, turn again and process second half, use inconvenience.
The utility model content
The purpose of the utility model provides a kind of suspension type center auxiliary stand of being convenient to elongated type of omnidistance camshaft of turning processing.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of camshaft suspension type center auxiliary stand, comprise the carriage that has the self-centering centre frame, and also comprise the crossbeam that is horizontally placed between two bracing frames; Carriage is positioned at the crossbeam below, and carriage and crossbeam are for removably connecting.
Said self-centering centre frame is positioned at the bearer carrier below of carriage, and bearer carrier removably connects through U-bolt and crossbeam.
The A/F of U-bolt and crossbeam width are suitable.
Crossbeam is a square column type, and the crossbeam lower surface is installed with backing plate, and bearer carrier is positioned at the backing plate below.
Said carriage is set to two, and the center distance of two carriages is not more than 500mm.
The utility model is applicable to engine lathe or numerically controlled lathe; Two bracing frames are stood on the lathe bed both sides of lathe, be used for supporting traverse, crossbeam plays the support positioning action to carriage; The self-centering centre frame of carriage is used to press from both sides the axle journal of establishing the supporting cam wheel axle, and then supports whole camshaft.Use U-bolt to connect carriage and crossbeam, can be convenient to suspension strut, locking, dismounting and movable support bracket station carriage.If camshaft is long, carriage can be provided with two as required, is convenient to support.Owing to carriage is arranged at the crossbeam below, no longer takies the position of lathe guide rail, so can realize the whole process of a turning processing slim class camshaft.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that A among Fig. 1 is to view.
The specific embodiment
A kind of camshaft suspension type center auxiliary stand by illustrated in figures 1 and 2 comprises carriage and is horizontally placed on the crossbeam 2 between two bracing frames 1 that crossbeam 2 is the horizontal beam of square column type; Backing plate 3, two bracing frames 1 that crossbeam 2 lower surfaces are installed with level are the relative vertical gripper shoes of two plate faces, and carriage is below the crossbeam 2, between two bracing frames 1; Carriage has self-centering centre frame 6 and bearer carrier 5; Bearer carrier 5 is a transverse slat, and self-centering centre frame 6 is a hydraulic self-centering centre frame 6, sets firmly a riser 8 in the middle of bearer carrier 5 downsides; Self-centering centre frame 6 bolts are connected in a side of riser 8, and riser 8 and self-centering centre frame 6 all are positioned at bearer carrier 5 belows of carriage.Bearer carrier 5 is positioned at backing plate 3 belows; Bearer carrier 5 removably connects with crossbeam 2 through two U-bolts 4; Open Side Down hangs on the crossbeam 2 for U-bolt 4, and loosening for preventing carriage, and the A/F of U-bolt 4 and crossbeam 2 width are suitable; Equal corresponding U-bolt 4 is provided with screw jack on bearer carrier 5 and the backing plate 3; Backing plate 3, bearer carrier 5 backs are inserted successively through nut 10 lockings in the end of U-bolt 4, and can between nut 10 and bearer carrier 5, cushion block 11 be set in order to lock, and so just carriage are hung on the crossbeam 2.
During work, two bracing frames 1 are fixed in the lathe bed both sides of lathe, self-centering centre frame 6 has three claws; The claw end is equipped with 7, three claws of roller and under the drive of hydraulic cylinder, stretches out synchronously and block camshaft 9 axle journals, and camshaft 9 drives rotation down at the lathe rotating disk; Roller 7 also rotates thereupon; The center of circle of the tangent circle of three rollers 7 is positioned at and adds on camshaft 9 the center line in man-hour, and promptly the axis of self-centering centre frame 6 is positioned on the lathe spindle axial line, realizes the self-centering function.The axle journal of the self-centering centre frame 6 supporting cam wheel axles 9 of carriage, and then support whole camshaft 9.Self-centering centre frame 6 is a prior art, so be not described in detail.
Certainly, the utility model is not limited to above-mentioned form, and when camshaft 9 was long, said carriage was provided with two of space sets.Center distance between lathe spindle flange and the carriage, between adjacent two carriages and the turning offset between carriage and the dead center are from being no more than 500mm.Can realize the whole process of a turning processing slim class camshaft 9.The described camshaft 9 suspension type center auxiliary stands of the utility model can be realized the whole process of a turning processing slim class camshaft 9.
