In the utility model, the quick-change joint part and the floating joint part are combined together organically. Which ensures the coaxial stable drive of the cutting tool and the drill press, enhances the accuracy of the making hole, and extends the service life of the cutting tool. The utility model has the advantages of compact structure, and convenient operation.
Description
The utility model belongs to the attachment technique field that is specially adapted for drilling machine.
On drilling machine, during machining hole, use the hydraulic quick coupler that do not stop to enhance productivity; When the length of fit of the leader of the cutter that machining hole is used and the drill bushing on the drill jig is longer, often select floating junction for use.Hydraulic quick coupler and floating junction are separately independently, and inconvenience is arranged during use; Floating junction is before putting into drill bushing to cutter, and cutter rotates and swings, and the operative employee can't make cutter and drill press spindle coaxial, so, might break blade in the moment of cutter being put into drill bushing.
The purpose of this utility model is a kind of combined joint of design, and this combined joint not only will possess the function of floating junction and hydraulic quick coupler, and before cutter was put into drill bushing, the rotation of cutter was not swung.
The utility model comprises that columniform work changes cover, the inside of changing cover is the mohs tapered bore that the center is provided with the axis living, the tool bore that unloads with the inner vertical connection of mohs tapered bore, on the side of changing cover of living, be socketed with the pole socket of floating lever, the floating lever middle part is provided with the driving hole with axis normal, the floating lever outside is set with the body seat of Mohs cone, Mohs cone body seat diameter of bore is greater than more than the floating lever external diameter 0.05mm, the middle part of Mohs cone is provided with the safety plug installing hole with its axis normal, on Mohs cone body seat, be equipped with body seat interference fit and pass the trundle and the flexible member that contacts with the floating lever lateral surface of driving hole, flexible member is divided into two rows, whenever drain into few three groups, every group evenly distributes on Mohs cone body seat, be provided with floating installation at axis position, floating lever upper surface, the other end of floating installation is fixed in the Mohs cone, the floating lever pole socket is provided with the hole of two symmetries, the transmission steel ball that dress cooperates with interporal lacuna in every hole, the lateral surface of floating lever pole socket is provided with upper spring back-up ring and lower spring back-up ring, floating lever pole socket outside is set with control loops, is provided with seam along the place in the bottom surface of control loops.
Mohs cone, floating installation, flexible member, trundle, floating lever and driving hole constitute the floating junction part, and cover, mohs tapered bore, transmission steel ball, control loops are changed in the pole socket of floating lever, work, check ring constitutes the hydraulic quick coupler part up and down.During use, the Mohs cone is connected mounting cutter in the mohs tapered bore that changes cover of living with drill press spindle.
Because the utility model organically combines hydraulic quick coupler part and floating junction part, both guaranteed the coaxial smooth rotation of cutter and drilling machine, do not swing, improve the precision in processed hole, prolong the service life of cutter, again than separately independently floating junction and hydraulic quick coupler unite and use compact conformation, easy to use, knock the phenomenon generation that influence the joint precision with wedge when having avoided the two is separated.
Describe concrete structure of the present utility model and operation principle in detail below in conjunction with drawings and Examples.
Accompanying drawing has provided embodiment of the present utility model, wherein:
Fig. 1 is the structural representation of embodiment;
Fig. 2 is the A-A profile of row's flexible member.
Columniform work change cover (1) with the axis be the center be provided with mohs tapered bore (2) and with the inner vertical connection of mohs tapered bore (2) unload tool bore (3), on the side of changing cover (1) of living, be socketed with the pole socket (5) of floating lever (4), floating lever (4) middle part is provided with the driving hole (6) with axis normal, floating lever (4) outside is set with the body seat (9) of Mohs cone (8), body seat (9) diameter of bore is greater than floating lever (4) external diameter 0.3mm, the middle part of Mohs cone (8) is provided with the safety plug installing hole (10) with its axis normal, on the body seat (9) of Mohs cone (8), be equipped with body seat (9) interference fit and pass the trundle (7) and the flexible member (11) that contacts with floating lever (4) lateral surface of moving hole (6), flexible member (11) is divided into two rows, four groups of every rows, every group of body seat (9) in Mohs cone (8) gone up evenly and distributed, every group of flexible member (11) comprises the removable pin (12) of serial connection, spring (13) and adjustment screw (14), be provided with floating installation (15) at axis position, floating lever (4) upper surface, floating installation (15) comprises the self-aligning spherical support nail (16) that is fixed on the axis position, floating lever (4) upper surface, be fixed on the tack supporting nail (17) in the Mohs cone (8), the pole socket (5) of floating lever (4) is provided with the hole of two symmetries, the transmission steel ball (18) that dress cooperates with interporal lacuna in every hole, pole socket (5) lateral surface of floating lever (4) is provided with upper spring back-up ring (21) and lower spring back-up ring (22), floating lever (4) pole socket (5) outside is set with control loops (19), is provided with seam (20) along the place in the bottom surface of control loops (19).
Operation principle of the present utility model is: because body seat (9) diameter of bore of Mohs cone (8) is greater than the external diameter of floating lever (4), between driving hole (6) on the floating lever (4) and the trundle (7) bigger gap is arranged, thus when work floating lever (4) relatively Mohs cone (8) can do a small amount of floating; Tack supporting nail (17) plays a part to transmit axial force with self-aligning spherical support nail (16) on the one hand, can obtain unsteady effect again on the other hand; During work the required cutting moment of torque be by drilling machine by Mohs cone (8) and body seat (9), trundle (7), floating lever (4), floating lever pole socket (5), pass to live by transmission steel ball (18) and change cover (1) again, pass to cutter at last; Flexible member (11) is to make the automatically reset key element of joint, removable pin (12) passes to floating lever (4) to the elastic force of spring (13), realize automatically reseting of joint, should carefully adjust the adjustment screw (14) of each group before using, by spring (13), the position of removable pin (12) fine setting floating lever (4) in body seat (9) endoporus of Mohs cone (8), the mohs tapered bore (2) that making lives changes on the cover (1) is coaxial with drill press spindle.The principle of the quick change cutter that do not stop of the present utility model is identical with the hydraulic quick coupler principle that tradition is used.
In use, cutter is contained in the mohs tapered bore (2), control loops (19) is upwards held up, change cover (1) living and pack in the pole socket (5) of floating lever (4), fall control loops (19); When getting cutter, control loops (19) is upwards held up, the seam (20) that makes transmission steel ball (18) slide into control loops (19) lower end is located, and just can change cover (1) living and take off together with cutter.
