Abstract
The invention discloses a special-purpose disk spring type clamping and loosening device of a lathe. The device comprises an electric spindle arranged in a spindle box. One side of the electric spindle is provided with a chuck. The hollow part of the electric spindle is sleeved with a clamping and loosening mechanism. The clamping and loosening mechanism comprises a bracing steel ball used for bracing the chuck. The bracing steel ball is connected with a pop rivet through a connection screw. The pop rivet is sleeved with a disk spring. One side of the pop rivet is connected with one side of a push rod. The other side of the push rod is provided with a single-action extrusion cylinder. By adopting the disk spring type clamping and loosening device, air pressure does not need to be provided for the cylinder in the machining process; after a workpiece is machined, the cylinder resupplies air pressure, a piston compresses the spring to move leftwards, the pop rivet is pushed through the push rod, the disk spring deforms after being compressed, the bracing steel ball moves leftwards, and the chuck retracts and immediately loosens the workpiece. According to the special disk spring type clamping and loosening device, in the whole cycle process, the air pressure needs to be supplied only when the workpiece is loosened, the cylinder only needs to work instantaneously, and accordingly the energy saving effect of the cylinder is achieved.

Further, a kind of special purpose lathe disk spring type clamping loosening device as above, cylinder terminal pad is equipped with bent plate support, the sense switch detecting piston position is arranged on bent plate support.
Further, a kind of special purpose lathe disk spring type clamping loosening device as above, cylinder side and opposite side are delivery port and water inlet respectively, and water inlet is communicated with delivery port through cylinder baffle, cylinder terminal pad, electro spindle inside, cylinder terminal pad, cylinder baffle.
Compared with the jack catchs type air clamper that the present invention and traditional numerically controlled lathe use, have that good stability, structure are simple, reliable clamping, assembling and easy to maintenance, the axiality requirement of processing work can be ensured, under the condition of High Rotation Speed, improve service life simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of special purpose lathe disk spring type of the present invention clamping loosening device.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, electro spindle 21 is arranged in main spindle box 8, jointly constitutes the main part of main shaft.Push rod 9 is set in the hollow space of electro spindle 21, and its one end is stretched out, and the other end is connected by the side of screw thread with blind rivet 3.Chuck 4 utilizes mounting screw 5 to be assemblied in electro spindle side, and chuck 4 is cut to 6 lobes in that side of mounting screw, is convenient to swelling workpiece.Chuck 4 is set with disk spring 7, and disk spring 7 side contacts with the boss of chuck 4, and the support set 6 that opposite side is installed in electro spindle 21 center compresses.The opposite side of blind rivet 3 is connected with stretching steel ball 2 by attachment screw 1, simultaneously stretching steel ball 2 land portions and chuck 4 interior side contacts.The opposite side of electro spindle is followed successively by cylinder terminal pad 12 and cylinder baffle 13, and cylinder back cover 16 is installed on the side of cylinder baffle 13 thus forms the sealed environment of cylinder, cylinder back cover is equipped with air inlet 17 for cylinder simultaneously and provides air pressure.It is inner that piston 14 is loaded on cylinder baffle 13, and both mating parts adopt O shape circle 19 sealing, and piston 14 is side pocketed springs 20 inwardly, when cylinder does not have the situation lower piston 14 of air pressure to bounce back under the pressure of spring 20.Whether cylinder terminal pad 12 is equipped with bent plate support 11, bent plate support 11 is equipped with sense switch 10, return put in place for detecting piston 14.Cylinder back cover 16 side and opposite side are water inlet 18 and the delivery port 15 of cooling fluid respectively, cooling fluid through water inlet 18, cylinder back cover 16, cylinder baffle 13, cylinder terminal pad 12, electro spindle 21 inside, cylinder terminal pad 12, cylinder baffle 13, cylinder back cover 16, delivery port 15, realizes the cooling to main shaft portion successively.
After air pressure enters cylinder by air inlet 17, piston 14 Compress Spring 20 move to push rod and contact with push rod 9 under the influence of air pressure, push rod 9 continues to move in the direction under the effect of cylinder, by the projection section of chuck 4 to this direction compact disc shape spring, stretching steel ball 2 moves to this direction with blind rivet 3, depart from chuck 4, chuck 4 automatic retracted, thus unclamp workpiece; After removal air pressure, piston 14 moves in the opposite direction thus departs from push rod 9 under the pressure of spring 20, blind rivet 3 moves along this rightabout with stretching steel ball 2 under the effect of disk spring restoring force simultaneously, and chuck 4 struts and then by Workpiece clamping by stretching steel ball 2.Sense switch 10 detects that piston 14 is return and puts in place, and now chuck 4 workpiece clamping action completes.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if belong within the scope of the claims in the present invention and equivalent technology thereof to these amendments of the present invention and modification, then the present invention is also intended to comprise these change and modification.
