Abstract
A hydraulic clamping device suitable for regulating spacing distance between an upper frame and a lower frame of a needle machine is characterized by comprising a hydraulic cylinder fixed on a wallboard, wherein a spring is arranged between a piston of the hydraulic cylinder and a base of the hydraulic cylinder, a piston shaft penetrates through a movable frame of a needle machine, the end of the piston shaft is provided with a fastening piece which is used for tightly pressing the movable frame, and the hydraulic cylinder controls oil to enter through an electromagnetic valve. When the hydraulic cylinder is under no-load, the shaft head of the hydraulic cylinder retracts under the thrust of a disc spring, double nuts on the shaft head can clamp the movable frame under the tension of the disc spring, the disc spring in the hydraulic cylinder can be compressed by oil pressure when oil enters the hydraulic cylinder through regulating the electromagnetic valve, then the shaft head in the hydraulic cylinder extends outwards, the movable frame is separated from the double nuts, and then the movable frame can move up and down under the effect of a lifter. The hydraulic clamping device has the advantages that the expansion of an inner shaft journal in the hydraulic cylinder is realized through regulating the electromagnetic valve, further the up-and-down motion of the movable frame is achieved, the connection strength is guaranteed, and the movable frame can be randomly regulated up and down when in necessary, which is convenient and reliable.
Description
Technical field
The utility model relates to hydraulic clamp, is specifically related to be applicable to the hydraulic clamp that the lower bearing bracket spacing is regulated on the needing machine, is a kind of jockey of realizing that the lower bearing bracket spacing is locked after regulating and regulating on the needing machine.
Background technology
Develop rapidly along with the non-weaving cloth technology, spacing can be regulated automatically between the upper and lower frame of a lot of weaving process requirement needing machines, with the accurate adjustment pricker degree of depth, about this just requires in the frame at least one can be done and move up and down, also need to guarantee the intensity that connects after the spacing adjustment finishes, traditional be threaded to be connected with key can't realize these functions.
Summary of the invention
The purpose of this utility model is just at the problems referred to above and custom-designed a kind of hydraulic clamp that is applicable to that lower bearing bracket spacing on the needing machine is regulated, when hydraulic cylinder is unloaded, hydraulic cylinder spindle nose retraction under the dish spring thrust in hydraulic cylinder, double nut clamps moving frame on the spindle nose under dish spring tension force; Regulate by electromagnetic valve, in oil entered hydraulic cylinder, oil pressure made dish spring compression in the hydraulic cylinder, and spindle nose is overhanging in the hydraulic cylinder, and moving frame separates with double nut, and this moment, moving frame was realized moving up and down under the lifter effect.
The purpose of this utility model is achieved through the following technical solutions: originally be applicable to the hydraulic clamp that the lower bearing bracket spacing is regulated on the needing machine, comprise the hydraulic cylinder that is fixed on the wallboard, be provided with spring between hydraulic cylinder piston and the hydraulic cylinder base, the axis of the piston passes the needing machine moving frame, the piston axle head is equipped with the anti-loose fastener that is used to compress moving frame, hydraulic cylinder is by the solenoid control oil-feed, at oil pressure effect lower compression spring, make axle journal overhanging, axle journal tightens firmware to be separated with moving frame, and then the realization moving frame is realized moving up and down under lifter is regulated.
In the utility model, moving frame can be the upper spider of needing machine, also can be the lower bearing bracket of needing machine.
Described anti-loosening securing member is that a double nuts structure or other have the nut of locking functions; The spring that is arranged in the hydraulic cylinder is the dish spring, to guarantee enough elastic force.
Advantage of the present utility model is: by stretching of axle journal in the electromagnetic valve adjusting realization hydraulic cylinder, and then the upper and lower of realization moving frame moved, both guaranteed the intensity that connects, realized also that the position of moving frame can be adjusted up and down when needed at any time, convenient and reliable.
Description of drawings
Accompanying drawing is a structural principle schematic diagram of the present utility model
Among the figure: 1. hydraulic cylinder, 2. dish spring, 3. moving frame, 4. wallboard, 5. double nut, 6. lifter
The specific embodiment
The utility model is described further below with reference to embodiment (accompanying drawing):
As shown in the figure: the electromagnetic valve that hydraulic clamp of the present utility model is used by double nut 5 on dish spring 2, the hydraulic cylinder axle journal in hydraulic cylinder 1, the hydraulic cylinder and control hydraulic cylinder is formed.Hydraulic cylinder is fixed on the wallboard 4, and when not having pressure in the hydraulic cylinder, double nut 5 compresses moving frame 3 on hydraulic cylinder axle journal under the dish spring tension force, realizes being fastenedly connected of moving frame; When in the electromagnetic valve regulator solution cylinder pressure during oil-feed, the cylinder neck is at oil pressure lower compression dish spring, and axle journal is overhanging, and double nut separates with moving frame on the axle journal, and moving frame 3 is realized moving up and down under lifter 6 is regulated.
