The distance at the two ends on the said groove two end distance honing pedestal length directions is 15-40mm.
The distance at the two ends on the said groove two end distance honing pedestal length directions is 30mm.
Said mandrel component comprises thick mandrel, the thin mandrel that is threaded with thick mandrel center, and carefully cover is useful on the compression spring that thick mandrel resets on the mandrel, and the taper surface and the honing pedestal of thick mandrel are connected.
Said universal joint assembly comprises universal joint, and universal joint is connected with honing head body with universal drive shaft through connecting pin, and universal joint axially and radially is respectively equipped with long column pin and stub pin, and the long column pin is fixedly connected with carefully mandrel is coaxial.
Adopt technique scheme, have following technique effect:
1, the original special-shaped elongated groove for the silk processing of being careful of the base seat groove on the honing head body, the utility model is improved to planar slot, and has increased reinforcement, has improved the intensity of body, and it is concentrated to have reduced the stress of body in processing and the use.
2, the planar slot manufacturing processing technic is easier, has reduced the residual stress of processing simultaneously, also helps the life-span of honing head body; Reduce the difficult point in the processing and manufacturing process, reduced percent defective, reduced processing cost.
3, the edges and corners at base seat groove two ends are equipped with the circular arc deep trouth, and dispersive stress guarantees not burst apart, and is prone to processing, improves working (machining) efficiency and service life.
4, the number of base seat groove and gib block groove and arrangement are for being applicable to the large aperture fine-processing technique.
5, the honing pedestal changes the face that has groove into by original plane, has reduced the contact area with base seat groove, makes contact more abundant; Extension spring is arranged in the arc groove, and during assembling, extension spring just in time is stuck in the arc groove, has effectively controlled moving of extension spring; The utility model reduces the difficult point in the processing and manufacturing process, has reduced percent defective, has reduced processing cost.
