Further, described body side is provided with detect aperture in the position of piston rod initial movable, the sheathed probe stretched in casing in detect aperture, and probe is positioned at one end linking springs sheet outside casing.
Further again, described spring leaf is provided with the displacement transducer of connection signal lamp.
Further, the screw top of described disc spring cylinder connects adjusting nut, and bottom is provided with the pressure head contacted with fixture block, and be provided with the disc spring in compressive state in the disc spring cylinder between pressure head and adjusting nut, described disc spring applies pressure by pressure head to fixture block.
Income effect: adopt hydraulic power simultaneously to realize fast by lathe slide plate and guide rail quick locking, the function of unclamping in conjunction with lever principle relative to prior art, utilize disc spring can regulate the size of coupling mechanism force, solve a difficult problem for fixed glides and guide rail position in machine tooling process, coupling mechanism force is large, time saving and energy saving, be convenient to locking and unclamp, avoid process middle slide plate and guide rail position uncertain, defective work piece or cutter.

Detailed description of the invention
Elaborate to embodiments of the invention below in conjunction with accompanying drawing, the present embodiment, premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
A kind of retaining mechanism as shown in Figure 1 and Figure 2, comprise casing 1, described casing 1 is connected to the below of lathe slide plate 9 by some screws, the structure be integrated with 9 one-tenth, lathe slide plate, as shown in Figure 6, between lathe slide plate 9 and retaining mechanism, be provided with guide rail 14, lathe slide plate 9 can move under unlocked state on guide rail 14, changes the relative position of guide rail 14 and lathe slide plate 9.
Retaining mechanism as shown in Figure 3, hydraulic cylinder 2 is provided with in casing 1, the cylinder body of hydraulic cylinder 2 is fixed among casing 1, the piston rod 3 of hydraulic cylinder 2 is parallel with lathe slide plate 9 lower surface, and extend from one end that cylinder body is fixed to the other end of casing 1, the end of piston rod 3 is provided with roller 4, this roller 4 times end in contact casing 1 bottom surfaces, upper end supports the clamp 5 arranged along piston rod 3 moving direction, and form lever with clamp 5, namely roller 4 is between clamp 5 and casing 1 inwall, and roller 4 can along with piston rod 3 rolls between clamp 5 and casing 1 inwall.Due to clamp 5 and roller 4 linear contact lay, under the support of roller 4, clamp 5 forms the lever that is the strong point with roller 4, the two ends of clamp 5 all convex to form the fixture block 6 stretched out outside casing, disc spring cylinder 7 is provided with above the fixture block 6 of hydraulic cylinder 1 one end, the guide rail 14 coordinated with lathe slide plate 9 is provided with above the fixture block 6 of clamp 5 other end, disc spring in described disc spring cylinder 78 pairs of clamp 5 one end apply pressure, one end tilting under making the other end of clamp 5 be positioned at guide rail 14 under roller 4 supports, realizes object guide rail 14 being applied to coupling mechanism force.
