Abstract
The utility model relates to a clamping device for fine machining of bearing hole of an assistant change gear shaft of a tractor. The clamping device is composed of a seat, a cone top and a pressing nut. The one end in the seat is mounted with a cone top, the center in the seat is fitted with a guide sleeve, and the other end in the seat is mounted with a conical ring with an opening. The conical ring with an opening is inner-fitted mounted with a pitch cylinder, and the pressing nut is fixed on the end surface of the seat. The utility model utilizes the clamping method of using the reference conical hole in fabrication of parts as the auxiliary supporting and limiting and centring, to grind the bearing hole under the circumstance of no or small changes of the reference of the fabrication of parts, reduces the influence caused by the change of reference, controls and ensures the precision of the mutual alignment of parts such as the support and the gear wheel, and satisfies the accuracy and function of the parts.
Description
Technical field
The utility model relates to the dead eye fine finishining anchor clamps field of the secondary change gear shaft of tractor, is the accurately machined clamping device of a kind of dead eye.
Background technology
Secondary variable-speed shaft is a strength member in the tractor transmission system.Have functions such as self two shifting gear transmission and other power transmission shaft of supporting.Part is after the carbon quenching heat treatment is quenched on the surface, and dead eye is wanted fine finishining, installs and the function of use effect to guarantee it.Usually when the working plate-like bore, adopt the pitch circle centralizer to process more.And the endoporus of big plate-like gear shaft is processed; Except that pitch circle centering guarantee the hole with gear coaxial; The other end of axle also must have more stable centering control and guarantee; Otherwise the two ends that receive axle add the man-hour out-of-alignment and change and influence, and the processing dimension of dead eye, shape and certain scattered error can occur with the positional precision at other position finally influence the result of use of part.
Summary of the invention
The purpose of the utility model is the dead eye fine finishining clamping device that the secondary change gear shaft of a kind of new tractor will be provided.
The technical scheme of the utility model is: by base, circular cone is top and jam nut is formed; It is top to it is characterized in that a end in base is equipped with circular cone; Centre in base is with guide pin bushing; The other end in base is equipped with the opening conical ring, is set with pitch cylinder in the opening conical ring, and jam nut is fixed on the end face of base.
Owing to adopted technique scheme, this device adopts pitch circle centering clamping, and utilizes part process benchmark taper hole to make the clamping means of aiding support, spacing centering.Keep the part processing benchmark to become less or constant situation under; The grinding dead eye; Reduce to reduce because of benchmark and change the influence that causes, thereby part precision and function of use are satisfied in the controlled and assurance of mutual alignment precision at positions such as the supporting that makes part and gear.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the drawings: 1, base; 2, circular cone is top; 3, guide pin bushing; 4, pitch cylinder; 5, opening conical ring; 6, jam nut.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
In Fig. 1, the end in the base 1 is equipped with that circular cone is top 2, and the centre in base 1 is with guide pin bushing 3, and the other end in base 1 is equipped with opening conical ring 5, is set with pitch cylinder 4 in the opening conical ring 5, and jam nut 6 is fixed on the end face of base 1.
The base 1 of this device is installed on the main shaft of internal grinder; Behind the specification requirement calibration centering conical surface, fastening seat 1, (the guide pin bushing endoporus should be slightly larger than part pinion external diameter to put into guide pin bushing 3; Supporting role when sending into to play; Conveniently send into operation, reduce the operator and be hold by one hand power, and be convenient to part taper hole and the applying of the top conical surface); The gear shaft part that to lay pitch cylinder 4 and opening conical ring more is along guide pin bushing 3 base 1 of packing into; Be close to the top conical surface when part process taper hole face, conical ring touch the base conical surface, compresses opening conical ring 5, makes its contraction and extruding pitch cylinder 4 be close to the flank of tooth, and functions such as spacing, the centering of finishing device, clamping are carried out inner hole grinding processing.What such installation way had kept feeling relieved in the part processing process one makes peace stablely, can control and guarantee the mutual position accuracy demand in each position of part, thereby satisfy the synthesis precision and the instructions for use of part.
