Abstract
The invention relates to mechanical manufacturing industries and discloses a guide rail locking mechanism which specifically comprises a pressing plate, a pressing head, a jacking rod, a hinge seat, a pressing plate, a rear cover, a gasket, an oil cylinder, an oil cylinder front cover, a piston, a supporting rod, a disc spring and a locking nut. The guide rail locking mechanism is formed by sequentially mounting the disc spring below the piston, mounting the gasket, screwing up with the locking nut, mounting in the oil cylinder, mounting the rear cover and the oil cylinder front cover, screwing the jacking rod in a portion, exposed out of the cylinder, on the piston, linking the oil cylinder on a base, connecting the pressing head on the pressing plate, connecting one of pressing plates on the hinge seat, linking the hinge seat on the other pressing plate, enabling the pressing plates to be linked on the base and pressed on a guide rail face, and mounting the jacking rod in holes of the pressing plates to act on the guide rail face through compression of the pressing head. Locking force of a sliding table guide rail is provided by the disc spring, and even if a lathe hydraulic system fails, the sliding table guide rail still can be locked reliably, so that rigidity of a sliding table can be improved, and vibration of a lathe during processing is reduced.
Description
Technical field
What the present invention relates to is machine industry, is specially a kind of guide rail locking mechanism.
Background technology
At present, the most of hydraulic locking that adopts of the locking of the guide rail of lathe, in case hydraulic locking generation systems fault in the machine tooling process, locking will be lost efficacy, and easily caused the machine tooling vibration, therefore this hydraulic locking mechanism is unreliable.
Summary of the invention
The purpose of this invention is to provide a kind of guide rail locking mechanism, it has improved the reliability of guide rail locking, and can improve the slide unit rigidity.
technical solution of the present invention is: a kind of guide rail locking mechanism, specifically comprise: pressing plate, pressure head, push rod, hinge seat, pressing plate, bonnet, packing ring, cylinder body, the oil cylinder protecgulum, piston, support bar, the dish spring, locking nut, the dish spring is contained in the below of piston, load onto packing ring, use again locking nut screwing, then pack in cylinder body, be loaded on bonnet and oil cylinder protecgulum, push rod is screwed in the part of exposing cylinder body on piston, at last oil cylinder is bound up on base, pressure head is connected on pressing plate, pressing plate is bound up on hinge seat, again hinge seat is bound up on pressing plate, at last with pressing plate with being bound up on base, and pressing guide pass, push rod is packed in the hole of pressing plate, compression by pressure head also will act on guide pass.
Advantage of the present invention is as follows: the coupling mechanism force of guide rail is provided by the dish spring, even machine tool hydraulic system breaks down, guide rail or locking reliably can improve the slide unit rigidity, the vibration when reducing machine tooling.
Description of drawings
The present invention is further described below in conjunction with drawings and embodiments.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
as shown in Figure 1, a kind of guide rail locking mechanism specifically comprises: pressing plate (1), pressure head (2), push rod (3), hinge seat (4), pressing plate (5), bonnet (6), packing ring (7), cylinder body (8), oil cylinder protecgulum (9), piston (10), support bar (11), dish spring (12), locking nut (13), dish spring (12) is contained in the below of piston (10), load onto packing ring (7), use again locking nut (13) to tighten, then pack in cylinder body (8), be loaded on bonnet (6) and oil cylinder protecgulum (9), push rod (3) is screwed in the part of exposing cylinder body (8) on piston (10), at last oil cylinder is bound up on base, pressure head (2) is connected on pressing plate (1), pressing plate (1) is bound up on hinge seat (4), again hinge seat (4) is bound up on pressing plate (5), at last with pressing plate (5) with being bound up on base, and pressing guide pass, push rod (3) is packed in the hole of pressing plate (5), compression by pressure head (2) also will act on guide pass.
specific works principle: during duty, piston (10) is under the effect of dish spring (12) spring force, head on pressing plate (1) by support bar (11) always, pressure head (2) on pressing plate (1) compresses push rod (3) again, push rod (3) acts on guide pass, play the function of locking, when slide unit need move, the upper square tube pressure oil of piston (10), pushing piston (10) makes dish spring (12) compression, piston (10) moves down and drives cramp bar (11) retraction, pressing plate (1) and pressure head (2) lift, push rod (3) produces the gap with guide pass, slide unit can move.
Claims (1)
1. a guide rail locking mechanism, comprise pressing plate (1), pressure head (2), push rod (3), hinge seat (4), pressing plate (5), bonnet (6), packing ring (7), cylinder body (8), oil cylinder protecgulum (9), piston (10), support bar (11), dish spring (12), locking nut (13), it is characterized in that, dish spring (12) is contained in the below of piston (10), load onto packing ring (7), use again locking nut (13) to tighten, then pack in cylinder body (8), be loaded on bonnet (6) and oil cylinder protecgulum (9), push rod (3) is screwed in the part of exposing cylinder body (8) on piston (10), at last oil cylinder is bound up on base, pressure head (2) is connected on pressing plate (1), pressing plate (1) is bound up on hinge seat (4), again hinge seat (4) is bound up on pressing plate (5), at last with pressing plate (5) with being bound up on base, and pressing guide pass, push rod (3) is packed in the hole of pressing plate (5), compression by pressure head (2) also will act on guide pass.
