Abstract

The invention provides the boring device for cutting of a kind of arbitrary shape hole and axle.

When driving parts such as Connection Block, moving body and cutter head cramping body when taper shank with the lathe main axle moving, moving body is under the effect of interchangeable template and traction wheel, driving the cutter head cramping body does corresponding flexible, the track that point of a knife moves along pre-designed interchangeable template promptly is the hole of required processing or the shape and the size of axle.

Description

The boring device for cutting of arbitrary shape hole and axle

The present invention relates to the boring device for cutting of a kind of arbitrary shape hole and axle.

This device can be processed the shape hole, 3-n limit of different size, and oval, the non-circular hole of shapes such as cam circle, oval and non-circular shaft, and the while also can be processed the circular hole and the circular shaft class part of different size.

On February 21st, 1986, a kind of multifunction machine boring frame is disclosed on the BP GB2162773A.It forms a space by taper shank, valve jacket and the panel of the machine tool chief axis of packing into, and knife rest is contained in the described space between rolling bearing movably.One rod member is housed in the taper shank, the inclined-plane of rod member and the motions that match such as the inclined-plane of knife rest and rocking arm, rod member is along axially-movable under the effect of driver and spring, and the inclined-plane of rod member then drives knife rest and does radial expansion, thereby realizes non-circular hole processing.The boring frame that documents is given must be equipped with special driver, and this driver does not provide in documents.Therefore the invention of documents can not directly be applied on existing lathe.

The objective of the invention is, provide a kind of and can replace the broaching tool of arbitrary shape and specification, the aperture knife tool of push broach, can process the boring device for cutting of the axial workpiece of arbitrary shape and different size simultaneously again.

Invention is achieved in that taper shank that the present invention includes the machine tool chief axis of packing into and the Connection Block that links to each other with taper shank, the moving body that can move radially is housed in the Connection Block, moving body is contained in the cavity set on the Connection Block, the traction seat of cutter head cramping body and adjustable position is housed in the moving body, wheel seat is housed on the traction seat, traction wheel is housed respectively on traction seat and the wheel seat, wheel seat can be around hinge through, cover is fixed on the sleeve of machine tool chief axis outside, interchangeable template is equipped with in the end of cover, this template is provided with mesopore, and a flange is arranged, and the traction wheel that is contained on the moving body can flexiblely be clamped flange, move along the line of shape shown in the flange with the traction moving body, when traction wheel drives moving body when interchangeable template flange-shape line moves, the cutter head cramping body also moves with moving body, thereby makes cutter head process hole shape shown in the template flange.

The invention provides and a kind ofly directly apply to the arbitrary shape hole of existing lathe and the process tool of axle, and do not need the special driver beyond the lathe, thereby overcome the shortcoming that the invention of documents just can not directly be used without creative work.

The concrete structure of invention is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is a primary structure view of the present invention.

Fig. 2 is cutd open and the partial view that draws by Figure 1A-A.

Fig. 3 is the partial view of working shaft-like part.

Fig. 4 is cutd open and the view that draws by Fig. 3 B-B.

Describe the concrete device provided by the invention and the course of work thereof in detail below in conjunction with Fig. 1 and Fig. 2.

This device comprises taper shank (1) that can insert in the machine tool chief axis and the Connection Block (5) that links with taper shank, and Connection Block (5) and taper shank (1) can be one.The moving body (12) that can move radially is housed on the Connection Block (5), rolling element (11) is housed between moving body and the Connection Block, its gap length is adjusted by panel (10).Cutter head cramping body (7) and traction seat (15) are housed on the moving body (12).Two traction wheels (21) are housed on the traction seat, traction wheel be contained in respectively on the traction seat axle (14) and on the wheel seat (16) that hinge (17) rotates.Traction wheel (21) can be circular, also can be (as square, hexagon etc.) of other shape.

Cover (2) is fastening with the part that does not rotate the machine tool chief axis outside, and cover (2) can be that monoblock type also can be an assembly type.Between cover (2) and the Connection Block (5) bearing (4) is housed, not establishing bearing (4) does not influence result of use of the present invention yet.Circlip (3) has limited the axial location of cover (2).Interchangeable template (8) connects with cover (2).Two traction wheels (21) are adjacent to the collar flange both sides of interchangeable template by elastic force, it is adjacent to power and realizes by screw (19) top elastomer (18), satisfying the smaller the better (see figure 3) of gauge H of collar flange under the situation of intensity, flange inner peripheral diverse location place during because of work between two traction wheels changes at any time by the distance at taper shank center, and the big more variation of H size is obvious more.The effect of elastomer (18) is to make outside traction wheel can not only be adjacent to flange when stressed, and certain amount of floating is arranged.Adjust the position of traction seat (15) according to the hole shape size after, with screw (20) that traction seat and moving body is fastening, load onto interchangeable template (8), make traction wheel be adjacent to template flange both sides, pretension screw (19) gets final product work again.The point of a knife of cutter head (22) is final processing dimension when the center overlaps with internal trolley (21).

Interchangeable template (8) is not rotated during work, and cutter head cramping body (7) rotates with main shaft.Because traction wheel (21) rolls along the flange shape of interchangeable template (8), do radial expansion simultaneously, realize the processing of non-circular hole or non-circular shaft and drive moving body (12).Adjusting device (9) is housed and the tight mechanism (not drawing among the figure) of stopping on the cutter head cramping body (7), adjusting device (9) is to fix its axial location by connecting plate (13).If the purpose of adjusting device (9) is, boring is cut surplus when big, and feed boring is several times cut to size.When point of a knife and traction wheel center are final processing dimension during at straight line.Pull down interchangeable template (8), screw (6) is fastening, just can process the circular hole and the circular shaft of different-diameter.

When processing circular shaft and non-circular shaft class part, should go up at cutter head cramping body (7) increases connection knife bar (23), and cutter head (22) should be contained in the tool bore that connects knife bar (seeing Fig. 3, Fig. 4).
