Abstract

The utility model discloses a disc-spring clamping oil cylinder. A piston rod is located in a cylinder body, a cross wall of the piston rod is matched with the inner wall of the cylinder body, and a disc spring and a washer matched with a vertical wall in internal diameter and matched with the inner wall of the cylinder body in external diameter are sequentially and penetratingly arranged on the vertical wall of the piston rod. The disc spring is butted against one end of the cross wall of the piston rod, a bushing is tightly assembled on the vertical wall of the piston rod at the outer end of the washer, and the bushing and the inner wall of the cylinder body opening at the end are clamped and fixed via a locking nut. A gland matched with the inner wall of the cylinder body in external diameter is fixed at the other end of the cross wall of the piston rod, and a sealing ring is jointed between the gland and the cross wall of the piston rod in a compression manner. A flange is fixed on the cylinder body opening at one end of the gland, an oil cavity is formed between the gland and the flange, a hole communicated with the oil cavity is formed in the side wall of the flange, and an oil pipe joint is mounted in the hole. By the disc-spring clamping oil cylinder, heating caused by long-term operation of a hydraulic system and personal casualties caused by sudden power failure can be effectively avoided, and energy resources are saved. The disc-spring clamping oil cylinder is fast in action, stable in system pressure and high in clamping and loosening reliability.

Description

Dish spring clamping cylinder
Technical field
The utility model relates to the clamping of a kind of guide rail for lathe relative movement, machine table, machine tool fixture or the locking cylinder unclamping.
Background technique
Guide rail, machine table, the clamping of machine tool fixture or traditional locking cylinder major part of unclamping for lathe relative movement are hydraulic clamp oil cylinders, unclamp and clamp all by hydraulic control, when needs clamp, hydraulic system needs long-term running, and particularly, when system pressure is had relatively high expectations, heating is very fast, executive component is easy to occur that action is insensitive, pressure surge, causes whole hydraulic system unstable, thereby affects the size of clamping force; And the long-term running of hydraulic system wastes energy; If there is accident power-off fuel cut-off in clamping process, can cause clamping anergy, executive component unclamps suddenly, and operator have little time to hide sometimes, can come to harm.
Summary of the invention
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, and a kind of dish spring clamping cylinder is provided, and this cylinder action is fast, and system pressure is stable, clamps and to unclamp reliability high; And can effectively avoid the generation of the artificial injures and deaths phenomenon because causing in the generation of the hydraulic system fever phenomenon that running causes for a long time and the situation of power-off suddenly, save the energy.
For achieving the above object, technical solution of the present utility model is: a kind of dish spring clamping cylinder, and it comprises cylinder body, flange plate, piston rod, gland, seal ring, locking nut, pad, lining, belleville spring and oil connection; Piston rod is positioned at cylinder body, and its cross wall and inboard wall of cylinder block match, the belleville spring and the pad that on its perpendicular wall, be installed with successively that internal diameter and perpendicular wall match, external diameter and inboard wall of cylinder block match; Belleville spring withstands on one end of piston rod cross wall, and the perpendicular wall of piston rod of pad outer end tightens and is equipped with lining, between lining and this end cylinder port inwall, by locking nut, is fixedly clamped; The piston rod cross wall the other end is fixed with the gland that external diameter and inboard wall of cylinder block match, and between gland and piston rod cross wall, is crimped with seal ring; In the cylinder port of gland one end, being fixed with flange plate, is oil pocket between gland and flange plate, has the hole being communicated with oil pocket on flange plate sidewall, and oil connection is installed in hole.
The utility model also comprises that oil is stifled, and the center of flange plate has the oilhole being communicated with oil pocket, and the stifled sealing of oil is fixed on this oilhole.
Seal ring described above is y-type seal ring.Its sealing effect is better, is difficult for leaking.
The utility model also comprises T-shaped, and T-shaped is threaded with piston-rod lower end.T-shaped for clamping action.
Under normality, the utility model, can be according to required clamping force in impaction state, and by calculating, the stroke of adjusting nut, produces certain precompressed to belleville spring; When the utility model being installed or unclamping the utility model, the pressure oil that need inject the pressure that matches by hydraulic pressure installation is opened.That is to say, the utility model is when clamped condition, hydraulic system can be in closed condition, when needs unclamp, primer fluid pressing system is opened, can effectively avoid the generation of the artificial injures and deaths phenomenon because causing in the generation of the hydraulic system fever phenomenon that running causes for a long time and the situation of power-off suddenly, save the energy.And its cylinder action is fast, system pressure is stable, clamps and to unclamp reliability high.
The utility model is divided into piston rod and gland by the conventional piston rod of oil hydraulic cylinder, so not only makes the easy to assembly of y-type seal ring, and can not cause damage to seal ring, extends the working life of fastening device.On flange plate, increasing oilhole and shutoff is in the situation that hydraulic pressure installation lost efficacy, and can also open oil stifled, lays down screw, opens clamp device, has guaranteed the reliability of the utility model clamping and release.
