Abstract
The utility model discloses a center hole rapid drilling device, consisting of a radial drilling machine (1), a rocker (2), a drill bit (3), a workpiece (4), a three-jaw chuck (5), a locking rocker (6), a tray (7), a rotary knob (8), a clamping groove (9), a bolt (10) and a center hole (11), wherein the three-jaw chuck (5) is fixed on the tray (7) through the clamping groove (9) on the tray (7) and the bolt (10), and the tray (7) is fixed on the radial drilling machine (1); the center hole rapid drilling device is characterized in that the clamping groove (9) is arranged on the tray (7), the three-jaw chuck (5) can be fixed at the set position of the clamping groove (9), and the included angle between the tray (7) and the radial drilling machine (1) is adjusted by the rotary knob (8). According to the center hole rapid drilling device, rapid clamping is achieved by the three-jaw chuck, so that the center hole can be rapidly drilled. Compared with traditional lathe drilling, the work efficiency is improved for more than 5 times, and meanwhile, the labor intensity of workers is reduced, and thus the machining cost is lowered.
Description
Technical field
The utility model relates to a kind of drilling equipment, particularly a kind of device for the quick centering of drill bit.
Background technology
Drill bit, in the process of processing, need to utilize the centre bore of one end of stock to locate and clamping.After fixed-length blanking, must first beat (drilling) in stock one end and go out centre bore.But the operated in accordance with conventional methods of centering is loaded down with trivial details on lathe, efficiency is low, has affected the productive temp of whole drill bit processing.The method of traditional centering is: clamping workpiece is on the main shaft scroll chuck of lathe, on the drill jig of centre drill clamping and tailstock.Utilize main shaft rotation (main motion), tailstock feeding carrys out centering.The shortcoming of this method is: workpiece is put into scroll chuck and wastes time and energy from the operating process of scroll chuck taking-up.Due to tailstock reach, force middle supporting plate and knife rest to be clipped between scroll chuck and tailstock, for short workpiece, just must claw be opened greatlyr, with from putting between claw or taking out.And workpiece is easy to get rid of curved when rotated, before processing, needs again to increase and align together operation.
Summary of the invention
For above problem, the purpose of this utility model is to provide the centre drilling device of a kind of quick-clamping, rapid drilling, quick pickup.
The technical solution adopted in the utility model is: a kind of centre drilling device fast, formed by radial drilling machine, rocking arm, drill bit, workpiece, scroll chuck, locking rocking arm, pallet, knob, draw-in groove, bolt and centre bore, scroll chuck is by the draw-in groove on pallet and being bolted on pallet, pallet is fixed on radial drilling machine, it is characterized in that: on described pallet, be provided with draw-in groove, scroll chuck can be fixed on the desired location of draw-in groove, adjusts the angle between pallet and radial drilling machine by knob.
On described pallet, be provided with a through hole, the internal diameter A of through hole is greater than the maximum grip workpiece external diameter B of scroll chuck, makes the workpiece of scroll chuck clamping pass through through hole;
On described scroll chuck, be provided with locking rocking arm, for clamping and unclamping workpiece.
The utility model structure, by scroll chuck quick-clamping, can reach the object of quick centering.Compared with processing with traditional lathe boring, operating efficiency improves more than 5 times, has reduced workman's labour intensity simultaneously, thereby has reduced processing cost, has improved the competitiveness of product in market.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the C of Fig. 1 is to view.
In figure: 1 radial drilling machine, 2 rocking arms, 3 drill bits, 4 workpiece, 5 scroll chucks, 6 locking rocking arms, 7 pallets, 8 knobs, 9 draw-in grooves, 10 bolts, 11 centre bores.
The specific embodiment
By Fig. 1, Fig. 2 knows, a kind of centre drilling device fast, and radial drilling machine 1, rocking arm 2, drill bit 3, workpiece 4, scroll chuck 5, locking rocking arm 6, pallet 7, knob 8, draw-in groove 9, bolt 10, centre bore 11 form.Scroll chuck 5 is fixed on pallet 7 by the draw-in groove 9 on pallet 7 and bolt 10, pallet 7 is fixed on radial drilling machine 1, on described pallet 7, be provided with a through hole, the internal diameter A of through hole is greater than the maximum grip workpiece external diameter B of scroll chuck, guarantees that any scroll chuck can holding workpiece can pass through through hole.When work, adjust the concentricity of centre bore 11 with the center line of bit of scroll chuck, workpiece from the hole A of pallet 7 from the bottom up place work piece 4 to correct position, pull locking rocking arm 6, locking workpiece 4, start radial drilling machine 1, depress rocking arm 2, workpiece 4 is carried out to bore operation, after completing, unclamp locking rocking arm 6, workpiece 4 freely falls.Clamping workpiece 4 again, carries out bore operation next time.
