Abstract
The invention relates to an automatically centering and rollably supporting center frame. The center frame is provided with a slide rail which is firmly fixed on a lathe and can slide back and forth on the lathe; slide blocks capable of sliding left and right are respectively arranged on the left end and the right end on the upper part of the slide rail; the bottoms of the slide blocks are in fit connection with a dovetail groove of the slide rail; the upper parts of the slide blocks are respectively provided with a jack catch, the upper end and the lower end of the inner side of the jack catch are respectively fixedly connected with idler wheels for fixing a turning piece; a long screw rod with positive and reverse threads passes through the middle parts of the slide blocks, one end of the long screw rod is connected with a handwheel, and the long screw rod rotates while the handwheel is rotated, thereby the jack catch is driven to do left-and-right opening and closing motion; the idler wheel on the jack catch clamps the turning piece to automatically locate, and other workpieces can be directly installed after one workpiece is located. The automatically centering and rollably supporting center frame not only can conveniently slide on the lathe, but also can conveniently, rapidly and precisely clamp the workpieces according to the size of the turning piece and be firm and reliable.
Description
Technical field
The present invention relates to a kind of lathe centre frame, specifically a kind of self-centering, rolling centre of support frame.
Background technology
At present, traditional centre frame is fixed on centre frame on the lathe guide rail by pressing plate at work, opens loam cake, and workpiece is put into centre frame, manually adjusts three back-up blocks, guarantees axiality, and the loam cake that closes tights a bolt, and can start lathe and process.
Existing problems:
1, manually adjust three strong point centerings, efficient is low;
2, between workpiece and the back-up block be sliding friction, easy to wear, the life-span is short;
3, three cylinder strong points belong to cantilever design, and rigidity is poor, easily vibration;
4, poor stability, traditional centre frame is by a tight fixed bolt, and fastening upper and lower covers in the processing, if workpiece centering effect is bad, easily twists off centre frame in the rotation, causes equipment, personal injury.
Summary of the invention
In order to solve the problem that existing lathe centre frame in use runs into, the present invention proposes self-centering, rolling centre of support frame, this centre frame adopts sections to support, improved support stiffness greatly, reduced vibrations, improved the quality, it can not only slide on lathe easily, and it is can block workpiece easily and fast, accurately, and solid and reliable according to car spare size.
The technical solution adopted for the present invention to solve the technical problems is: this self-centering, rolling centre of support frame are mainly by guide rail locking block, bolt, and rail plate, left plate, limiting plate, screw stock, slide block, claw, roller, handwheel and right plate are formed; This novel lathe centre frame has a rail plate that can coincide with the guide rail above the lathe, the centre of this rail plate is provided with through hole, the two bottom sides of guide rail is provided with " ∧ " connected in star, and sliding connection can coincide with " ∧ " shape guide rail on the lathe; The bottom of rail plate with the through hole correspondence position, is provided with the guide rail locking block, and it is firmly fixed on the lathe rail plate by bolt; In the left and right sides of rail plate, be respectively arranged with vertical left plate and right plate; Between left plate, right plate, be provided with the screw stock of forward and reverse silk, on left plate and right plate, the screw stock extends to the right plate outside of band through hole to the screw stock, passes the side plate end cap and fixedly is rotatably connected with handwheel by roller bearings; The both sides of screw stock are separately installed with nut, and the outside fixed order of nut is connected with slide block and claw, by nut screw stock, slide block and claw is connected as one motion, and is fixed by screw; The bottom of slide block is connected with rail plate dovetail groove sliding fit; Be respectively arranged with limiting plate between left plate, right plate and the slide block, in case limited slip block de-orbits; The upper and lower end of claw inboard is fixedly connected with roller respectively, and the middle part is " V " connected in star, is used for fixing car spare.
The invention has the beneficial effects as follows: this self-centering, rolling centre of support frame can not only slide on lathe easily, and can block workpiece easily and fast, accurately according to car spare size, and solid and reliable.
