Description
Technical field
The utility model relates to spring art, particularly relates to the improvement to disk-shape spring structure.
Background technique
Belleville spring is called for short disc spring, compares traditional helical spring, and because its load is large, stroke is short, and requisite space is little, and combinationally use conveniently, maintenance changes the outfit easily, and economy and security is high.Be applicable to space little, the accurate hoisting machinery that load is large, such as high-speed numeric control mould.Due on the die shank that belleville spring is set in mould usually or on the coupling shaft of equipment, and be Spielpassung, namely the through-hole diameter of belleville spring is greater than the die shank diameter of mould or the coupling shaft diameter of equipment, make when high speed stamping, motion, there are the following problems: produce vibration between (1), belleville spring, energy is difficult to release, affects the measure of precision of mould or equipment; (2), vibration time, belleville spring produces micro-ly beats, and rotates, and affects Belleville spring buffering effect; (3) cross section of belleville spring is the arc-shaped of concave, and after lathe drift presses down, the arc-shaped of concave becomes to the trend of turning up, and after lathe drift lifts, belleville spring resets again.But when resetting, belleville spring changes indent into by the trend of turning up, when lathe drift active force is large, when causing the belleville spring trend of turning up to reach certain limit, belleville spring easily produces distortion, fracture, gently then causes the damage of belleville spring, heavy then cause the damage of mould, lathe.
Model utility content
The utility model is for above problem, and provide a kind of raising and locate and spring strength, antivibration is effective, improves reset speed, prevents the belleville spring of camber of spring.
The technical solution of the utility model is: comprise disc spring body, reset supporting layer and vibration absorbing layer, described disc spring body is provided with through hole one, described reset supporting layer in the form of a ring, cross section be evagination arc-shaped, be located on the inner arc surface of described disc spring body, described vibration absorbing layer is located on the exterior arc surface of described disc spring body;
Described vibration absorbing layer is provided with some through holes two;
Described through hole one is provided with a pair positioning groove, described positioning groove and axially runs through described disc spring body and vibration absorbing layer;
Described disc spring body is provided with at least one pair of radiating groove, and described radiating groove runs through described vibration absorbing layer;
Described reset supporting layer and vibration absorbing layer are elasitic layer.
Described disc spring body is plane away from the bottom surface of the end of central shaft.
Described elasitic layer adopts rubber or silica gel material.
The degree of depth of described radiating groove is the 1/10-1/9 of described disc spring body thickness.
Reset supporting layer in the utility model and vibration absorbing layer all have elasticity, rubber or silica gel can be adopted to make, by vibration absorbing layer being covered on the exterior arc surface of disc spring body, the vibration produced when utilizing elasticity to absorb high speed stamping, shock, there is anti-effect of quivering, the machining accuracy of raising equipment, also effectively prevents disc spring body distortion.And the ring-type reset supporting layer be located on disc spring body inner arc surface, when disc spring body is impacted, arc surface is to providing support power and attachment force when turning up, and the reset supporting layer of outer convex type promotes disc spring body reset speed simultaneously, improves work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the plan view of Fig. 1,
Fig. 3 is the worm's eye view of Fig. 1,

Embodiment
The utility model as Figure 1-4, comprise disc spring body 1, reset supporting layer 2 and vibration absorbing layer 3, described disc spring body 1 is provided with through hole 1, for being set in mould or equipment, described reset supporting layer 2 in the form of a ring, cross section be evagination arc-shaped (the circular arc direction of reset supporting layer is contrary with disc spring body circular arc direction), be located on the inner arc surface of described disc spring body 1, be wherein good to be located at the middle part of disc spring body 1 inner arc surface, described vibration absorbing layer 3 is located on the exterior arc surface of described disc spring body 1;
Described vibration absorbing layer 3 is provided with some through holes 2 31, for heat radiation, buffering vibration, intercepts the continuous propagation of vibration;
Described through hole 1 is provided with a pair positioning groove 12, described positioning groove 12 and axially runs through described disc spring body 1 and vibration absorbing layer 3, by positioning key, described disc spring body 1 is fixed with the corresponding fixed groove on mould or equipment, avoid when high speed stamping, the rotary motion of disc spring body output, reduction cushioning effect;
Described disc spring body 1 is provided with at least one pair of radiating groove 13, and described radiating groove 13 runs through described vibration absorbing layer 3;
Described reset supporting layer 2 and vibration absorbing layer 3 are elasitic layer.
Described disc spring body 1 is plane 14 away from the bottom surface of the end of central shaft, in order to increase the area of contact between two disc spring bodies positioned opposite, improves stability, prevents disc spring body local pressure, affect usability.
Described elasitic layer adopts rubber or silica gel material.
During due to work, belleville spring extrudes mutually, impact process produces heat, dispelled the heat by described radiating groove 13 and through hole 2 31, the degree of depth of described radiating groove 13 is the 1/10-1/9 of described disc spring body 1 thickness, guarantee that radiating groove 13 is while heat radiation, avoid radiating groove 13 degree of depth to cross dark generation and be out of shape or fracture.
