Description
Technical field
The utility model relates to a kind of fluid power control pressurize supercharging bench vice structure, belongs to the compound clamping control device of mechanical-hydraulic, and the pressure when being mainly used in the bench vice clamping work pieces keeps and the pressure adjustment.
Background technology
In the application principle of bench vice; There are two kinds at present, the one, the mechanical type drive mechanism is the trapezoid spiral auxiliary driving, the size of bench vice clamping work pieces power applies the torque decision by the operator; When caught workpiece is a rigid body; The occasion of vibration influence is being arranged, and secondary can the generation of the trapezoid spiral of bench vice become flexible, and the mechanical type bench vice clamped lost efficacy; The 2nd, fluid pressure type clamping bench clamp structure; The hydraulic clamp structure has overcome the not shortcoming of antidetonation of mechanical type bench vice; Existing fluid pressure type bench vice is secondary with the trapezoid spiral that hydraulic cylinder replaces in the mechanical type; Its hydraulic power supply controls supply automatically according to hydraulic system or the hand supercharging device provides, and complex structure and volume are bigger, and is difficult for moving.
Summary of the invention
For the better reliable clamping that realizes bench vice, use simple and easy; Occupy the little requirement in space, the utility model provide a kind of rational in infrastructure, be easy to make, the fluid power pressurize booster-type bench vice application structure of handiness, this application structure is improved on the basis of universal machine formula bench vice and is designed; Mechanical type trapezoid spiral screw mandrel is made hollow structure; The built-in axle of realizing the pressurize pressurization is housed in hollow screw mandrel, and the screw mandrel operating side of moved jaw is designed to combined mechanism, accomplishes fast moving and the predetermined torque value of jaw when operating mechanism links and clamps; When continuation applies moment of torsion to operating grip; The mechanical type trapezoidal screw receives the square mechanism's effect of spring compression limit and stops operating, and the operation transmission mechanism of separation acts on built-in liquid spring structure through wrench shaft, makes the built-in axle in trapezoidal screw hole produce axial force; Built-in axle holds out against jaw, under the liquid spring effect, produces the effect of pressurize supercharging.
The technical scheme of the utility model is: the bench vice that is used for fluid power pressurize supercharging; Comprise bench vice lower body, jaw plate, jacking block, moved jaw, screw mandrel, nut, built-in axle, end cap, screw, compression spring, piston, plunger, handle body, taper knob, wrench shaft, pin, screw, slip goalpost, sealing ring, packing ring, hydraulic oil; Described moved jaw one end is fixed with jacking block; The other end carries out axial limiting through endoporus and split end cap to screw mandrel and cooperates, and screw mandrel fits in the screw pair with the nut that is fixed on the bench vice lower body, and the fast moving of accomplishing moved jaw clamps; Screw mandrel is realized axial limiting through the step shaft portion of setting and the end endoporus and the end cap of moved jaw; Described screw mandrel is designed to hollow structure, in the screw mandrel endoporus, is equipped with built-in axle, and the end of screw mandrel is connected with handle body through binding thread; Handle body is fastening through screw and screw mandrel, and described handle body indoor design has built-in being coupling of piston and screw mandrel to touch; Handle body inside also is designed with plunger, and plunger moves axially at the handle body endoporus, and the one of which end stretches in the cavity of handle body and piston formation, and the other end contacts with the wrench shaft end face of flange; Be designed with the groove of taking in of slip pin on the described wrench shaft end face of flange; The handle body other end is fixed with end cap through pin, and end cap is equipped with slip goalpost, compression spring, adjustment screw vertically, and the sphere of slip goalpost is taken the groove cooperation in the end face of flange of wrench shaft and contacted; Described wrench shaft forms with end cap through binding thread and cooperates; The inner chamber that described piston and wrench body endoporus form is full of hydraulic oil; Piston and screw mandrel are designed with the compression spring on axial end, described built-in axle bore design has the compression spring; Described moved jaw endoporus and split end cap leave micro-end play to the axial limiting cooperation that screw mandrel carries out.On described taper knob, be designed with the handle hole that carries out screw adjusted sliding ball column pressure.
During application, workpiece is positioned between the jaw plate of bench vice lower body and moved jaw, the rotating spanner axle, thus wrench shaft rotates through the moving slip goalpost interlock of the troughed belt screw mandrel of taking on it, realizes the fast moving clamping action of mechanical type bench vice.When bench vice clamping work pieces power reaches preset value; The groove of taking on the ball head structure of sliding ball column end and the wrench shaft produces slip/stick movement; Stop operating with the joining screw mandrel of slip goalpost; Wrench shaft carries out axially-movable through the screw thread transmission with respect to the end cap in the wrench body, and the wrench shaft axially-movable promotes plunger advancement, and plunger compression handles body and piston form the hydraulic oil in the cavity; The pressure of hydraulic oil acts on the built-in axle that promotes piston on the piston and link to each other with piston; To being fixed on the jacking block effect on the moved jaw, produce the pressurize pressurized effect of moving jaw under the fluid power effect through built-in axle, the reaction force under the fluid power effect passes to the nut that is fixed on the bench vice lower body through the combination screw structure.The step shaft portion of described screw mandrel axially leaves certain fluid power effect gap when cooperating with the moved jaw hole, moved jaw can continue micro-mobile when guaranteeing under the fluid power effect pressurize supercharging.
Wrench shaft moment of torsion preset value under the described hydraulic booster formula bench vice mechanical type clamping action is regulated the pressure of slip goalpost through screw compression spring.
When bench vice unclamps, the backward rotation wrench shaft, the quick rollback of feed screw nut pair unclamps the jaw workpiece, and the goalpost of sliding simultaneously slides into goalpost at the smooth end face of wrench shaft and falls into the original position of taking groove in, and the piston in the wrench body is compressing rollback under the spring action with built-in axle.
The described hydraulic booster formula of the utility model bench vice had both had the structure and the application characteristic of mechanical type bench vice, had increased fluid power pressurize supercharging device again, and need not extraneous hydraulic power provides, simple and reliable for structure, convenient to use.Can effectively prevent to shake the loosening inefficacy unstability of clamping work pieces under the occasion.
