Abstract
The utility model relates to a clamp structure for precise machining of an aluminium die-cast valve cap. The clamp structure comprises a clamp pressing block, a cylinder I and a cylinder II, wherein the cylinder I is vertically arranged on the upper end surface on one side of a machine body; an oblique slide block which moves vertically is arranged at the upper end of the cylinder I; the cylinder II is transversely arranged in the middle on one side of a bracket perpendicularly connected with the machine body; a piston rod, of which one end is connected with the cylinder II, transversely penetrates through the bracket; the other end of the piston rod is rotationally connected with one end of a lever pressing plate through a piston pillar; the lever pressing plate is vertically arranged above the oblique slide block; the middle of the lever pressing plate is connected with the bracket through a lever pillar; the other end of the lever press plate rotates around the lever pillar and is contacted with the clamp pressing block. The clamp structure is simple in structure, comprises two sets of cylinders, and amplifies the clamping force of the cylinders many folds by virtue of the lever principle and the slope self-locking principle.
Description
Technical field
The utility model relates to fixture field, particularly relates to a kind of for the precision machined clamp structure of aluminium die casting valve gap.
Background technology
At aluminium die casting valve gap, after die casting, toward contact, need to carry out fine finishining.General clamp for machining is cylinder or oil cylinder, by this valve gap of vertical compression, processes.Oil cylinder is the linear motion type executive component that the pressure differential on power output and piston effective area and both sides thereof is directly proportional, and converts hydraulic energy to mechanical energy.Oil cylinder clamp pressing power is large, but needs configure dedicated font station, takes up room large, clean not, and also can cause environmental pollution.Cylinder moves piston by compressed air, the power source clean environment firendly of cylinder, but thrust is less, and bleed pressure is unstable, easily causes the fluctuation of accessory size.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of for the precision machined clamp structure of aluminium die casting valve gap, simple in structure, two groups of cylinders, consists of, and utilizes lever principle and gradient self-lock mechanism, and the clamping force of cylinder is amplified at double.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of for the precision machined clamp structure of aluminium die casting valve gap, comprise fixture briquetting, cylinder I and cylinder II, described cylinder I is vertically arranged on the upper surface of fuselage one side, its upper end is furnished with the angled-lift splits of vertical movement, described cylinder II lateral arrangement is at the middle side part with the vertical support being connected of fuselage, described internal stent is horizontally through the piston rod that one end is connected with cylinder II, the other end of described piston rod is rotatedly connected by piston pillar and lever pressing plate one end, described lever pressing plate is vertically arranged in the top of angled-lift splits, its middle part is connected with support by lever pillar, the other end of described lever pressing plate rotates and contacts with fixture briquetting around lever pillar.
On described rack side wall and between angled-lift splits, block is installed.
Upper end, side near lever pressing plate on described angled-lift splits is furnished with inclined-plane.
The middle part of described lever pressing plate is rotatedly connected by one end of lever pillar and horizontally disposed lever dolly, and the described lever dolly other end is fixed by being embedded into internal stent.
After described angled-lift splits vertically rises, the disembark distance of body of upper surface is greater than the disembark distance of body of lever pressing plate lower end.
beneficial effect
The utility model relates to a kind of for the precision machined clamp structure of aluminium die casting valve gap, simple in structure, two groups of cylinders, consists of, and utilizes lever principle and gradient self-lock mechanism, and the clamping force of cylinder is amplified at double.
