Abstract
The utility model discloses a simple drive-type expansion sleeve structure, and the simple drive-type expansion sleeve structure comprises a shaft sleeve, and the simple drive-type expansion sleeve structure is characterized in that a stepped through hole is arranged inside the shaft sleeve, wherein two ends of the stepped through hole are respectively of a flared hole, the side wall of the shaft sleeve is provided with axial adjusting grooves, a circular buffering hole which is communicated with each axial adjusting groove is arranged between one end of each axial adjusting groove and the shaft sleeve, each axial adjusting groove comprises an upper end surface axial adjusting groove and a lower end surface axial adjusting groove, the upper end surface axial adjusting groove is communicated with the upper end surface of the shaft sleeve, and the lower end surface axial adjusting groove is communicated with the lower end surface of the shaft sleeve. The simple drive-type expansion sleeve structure is reasonable in structural design, two ends of the shaft sleeve can be expanded, the clamping stability also can be improved, the simple drive-type expansion sleeve structure is not easy to damage after being used for a long time, and the service life of the expansion sleeve can be guaranteed.
Description
Technical field
The utility model relates to a kind of ringfeder structure, relates in particular to a kind of simple drive-type ringfeder structure.
Background technique
At present, existing ringfeder is simple in structure, mostly adopts simple axle sleeve type structure; On the sidewall of axle sleeve, offer the axial adjustment groove, in use axle sleeve can only an end spreading, thereby cooperates with workpiece to be clamped; It is simple in structure, can not realize two ends spreading simultaneously, and the poor stability that clamps; After long-term the use, damage easily, influence the working life of ringfeder.
The model utility content
The purpose of the utility model is in order to remedy the deficiency of prior art; A kind of simple drive-type ringfeder structure is provided, and it is simple in structure to have solved existing ringfeder, can not realize two ends spreading simultaneously; And the poor stability that clamps; After long-term the use, damage easily, influence the problems such as working life of ringfeder.
The utility model is realized through following technological scheme:
A kind of simple drive-type ringfeder structure; Include axle sleeve; It is characterized in that: be provided with step through-hole in the said axle sleeve, the two ends of said step through-hole are respectively flared hole, are distributed with the axial adjustment groove on the said axle sleeve sidewall; Be provided with the circular cushion hole that is communicated with the axial adjustment groove between described axial adjustment groove one end and the axle sleeve; Said axial adjustment groove includes upper-end surface axial adjustment groove and lower end surface axial adjustment groove, and said upper-end surface axial adjustment groove is communicated with the upper-end surface of axle sleeve, and said lower end surface axial adjustment groove is communicated with the lower end surface of axle sleeve.。
Described axle sleeve is the 65Mn round steel, and the angle of described flared hole is 40-90 °.
Being evenly distributed on the axle sleeve of described said upper-end surface axial adjustment groove and lower end surface axial adjustment groove interval.
Its principle is: step through-hole through axle sleeve two ends band flared hole and upper-end surface axial adjustment groove and lower end surface axial adjustment groove close the structural design that compartment distributes; Can realize axle sleeve two ends spreading; Improved the stability that clamps simultaneously; After long-term the use, be not easy to damage, guaranteed the working life of ringfeder.
The ringfeder material is that (the 65Mn round steel has excellent comprehensive performances to the 65Mn round steel; As mechanical property (particularly limit of elasticity, ultimate strength, yield ratio), elasticity attenuation resistance can (be the elastoresistance performance that goes down, claim anti-relaxation property again), fatigue behaviour, hardenability, physical and chemical performance (heat-resisting, low temperature resistant, anti-oxidant, corrosion-resistant etc.).
Ringfeder needs bulk heat treatment: 850 degree oil quenching 400-430 degree tempering 1H hardness guarantee high hardness and better elastic at HRC40-45.
The utility model has the advantages that:
The utility model reasonable in design can realize axle sleeve two ends spreading, has improved the stability that clamps simultaneously, after long-term the use, is not easy to damage, and has guaranteed the working life of ringfeder.
