Abstract
The utility model provides an assembled center hole drilling tool and adopts the technical scheme as follows: an immovable finial is mounted on a three jaw chuck of a lathe; a movable finial is supported in a finial body through a rolling bearing; a taper-shank mandrel are connected with three guide poles through a clamping ring and countersunk head screw; a rear cover is hermetically connected with the finial body through threads; a center hole drill head is mounted in a hole at the left end of the taper-shank mandrel and fixed through a bolt; three springs are mounted in three small holes of the finial body and propped against the three guide poles respectively; a stop screw is connected with the clamping ring; the taper-shank mandrel is in clearance fit with the movable finial and the finial body and drives the movable finial and the finial body to linearly move through the joint push of the guide poles and the clamping ring. The utility model has the benefits of simple structure, convenient operation, accurate positioning, strong universality, high processing efficiency and suitability for batch processing of products.
Description
Technical field
The utility model relates to a kind of assembled centre bore drilling tool, relates in particular to the drilling tool of Machining of Shaft-type Parts centre bore, belongs to field of machining.
Background technology
Workpiece processing, particularly during Machining of Shaft-type Parts, all need be in machining center hole, the one or both ends of axle, to satisfy the needs of following process.Conventional is that the scroll chuck of lathe is clamped an end of processing axle with the machined into centre bore, proofreaies and correct the center of processing axle, uses the other end machining center hole of the interior start(ing) drill of tail stock sleeve to axle again.Adopt this method machining center hole, operating efficiency is low, owing to proofread and correct by naked eyes control, the centre bore size of coaxial two ends or the processing of similar profile shaft and the degree of depth are difficult to guarantee in full accord, influence product lot quantity processing.
Summary of the invention
The purpose of this utility model just provides a kind of assembled centre bore drilling tool, addresses the above problem.
The technical solution of the utility model is: on the motionless top scroll chuck that is installed in lathe, move top by roller bearings in top body, the taper shank axle is connected by trim ring and sunk screw with three guide pillars, the bonnet sealing that links to each other with top body screw thread, start(ing) drill is installed in the taper shank axle left end hole, fix by screw, in three apertures of top body three springs are housed and head on three guide pillars respectively, stop screw links to each other with trim ring, the taper shank axle is joined with mobile top and top body work, connection by guide pillar and trim ring promotes, and drives mobile top and top body and moves as straight line.
The beneficial effects of the utility model are: simple in structure, easy to operate, location accurately, highly versatile, working (machining) efficiency height are applicable to the batch machining of product.
Description of drawings

Fig. 2 is the utility model work schematic diagram.
The specific embodiment
With reference to accompanying drawing 1 as can be known, a kind of assembled centre bore drilling tool, motionless top (1) is installed on the scroll chuck (15) of lathe, moving top (4) is supported in the top body (9) by rolling bearing (5), taper shank axle (14) and three guide pillars (8) are connected as a single entity by trim ring (10) and sunk screw (11), bonnet (12) links to each other with top body (9) screw thread, seal, start(ing) drill (3) is installed in taper shank axle (14) the left end hole, and it is fixing by holding screw (6), three springs (7) are installed in three apertures of top body (9), head on three guide pillars (8) respectively, stop screw (13) links to each other with trim ring (10) by screw thread, taper shank axle (14) is lived with mobile top (4) and top body (9) and is joined, by with the thrust that is connected of guide pillar (8) and trim ring (10), drive and move top (4) and top body (9) moves as straight line.
With reference to accompanying drawing 2 as can be known, a kind of its operating characteristic of assembled centre bore drilling tool is: with motionless top (1) clamping on the scroll chuck (15) of lathe, the taper shank of taper shank axle (14) is put in the tail stock sleeve, after treating that lathe is opened, rotate the tailstock handwheel, barrel of tail stock is stretched out forward, when treating that workpiece (2) two ends hold out against between motionless top (1) and mobile top (4), workpiece and two toply rotates with lathe spindle, be rotated further the tailstock handwheel, three springs (7) in the top body (9) are compressed, taper shank axle (14) in top body (9) to workpiece (2) direction feeding, start(ing) drill this moment (3) carries out machining, and by stop screw (13) control processing dimension, has so far finished the processing of workpiece one end centre bore.Backward rotation tailstock handwheel again, make the barrel of tail stock withdrawal, this drilling tool also together returns, wait to turn back to two top when not having workpiece pressing and not breaking away from workpiece, having only the lathe spindle band motionless top (1) idle running, stops the rotation in workpiece (2) and mobile top (4), takes off workpiece (2) and tune, repeat said process, finish the processing of other end centre bore.
Claims (1)
1. assembled centre bore drilling tool, it is characterized in that: motionless top (1) is installed on the scroll chuck (15) of lathe, moving top (4) is supported in the top body (9) by rolling bearing (5), taper shank axle (14) is connected by trim ring (10) and sunk screw (11) with three guide pillars (8), bonnet (12) sealing that links to each other with top body (9) screw thread, start(ing) drill (3) is installed in taper shank axle (14) the left end hole, fixing by screw (6), in three apertures of top body (9) three springs (7) are housed, head on three guide pillars (8) respectively, stop screw (13) links to each other with trim ring (10), and taper shank axle (14) is lived with mobile top (4) and top body (9) and joined.
