Description
Technical field
The utility model relates to machine tool field, specifically a kind of operating grip neutral self-locking mechanism.
Background technology
Lathe is the important production equipment for processing equipment parts in modern industry, in national modernization construction, play important effect.Lathe axis class handle is conventional lathe component part, plays the effect of transmitting power.In actual use, often because maloperation appears in External Force Acting, there is certain potential safety hazard in lathe axis class handle.
Utility model content
The purpose of this utility model is to provide a kind of operating grip neutral self-locking mechanism, to solve the problem of the easy maloperation of prior art lathe axis class handle.
In order to achieve the above object, the technical scheme that the utility model adopts is:
Operating grip neutral self-locking mechanism, include feeding seat, it is characterized in that: in feeding seat, be provided with central shaft axis hole in left-right direction, axis hole right-hand member is set to necking, poke rod axle is rotatablely equipped with in axis hole, poke rod axle right-hand member stretches out feeding seat and is provided with handle set, and poke rod axle right part is set to coordinate the step-like of necking, poke rod axle centre position in axis hole is provided with land, land sidewall is provided with self-locking grooves, and be connected with the Compress Spring one be enclosed within poke rod axle between land and axis hole necking mouth wall, in described feeding seat, side has central shaft pin groove along the longitudinal direction, to stagger left certain distance relative to poke rod axle self-locking grooves position in pin groove position, the inner of pin groove is along aperture axis to being communicated to axis hole, the outer end of pin groove is arranged on front side of feeding seat or on rear side sidewall, locking pin is slidably fitted with along the longitudinal direction in pin groove, locking pin pin end stretches in axis hole in the self-locking grooves also can sold on poke rod axle sidewall.
Described operating grip neutral self-locking mechanism, it is characterized in that: in described feeding seat, side also has central shaft spring groove along the longitudinal direction, the inner of spring groove is along aperture axis to being communicated to axis hole, the outer end of spring groove is separately positioned on front side of feeding seat or on rear side sidewall, in spring groove, outer end is fixed with spring base, spring base is connected with Compress Spring two, Compress Spring two stretches in axis hole along the longitudinal direction, and Compress Spring two spring end is connected with the locking ball supported on poke rod axle.
In the utility model, when poke rod axle be provided with handle set be in neutral position time, it is corresponding with pin groove position that poke rod axle entirety is moved to the left self-locking grooves position under the effect of Compress Spring one, now in pin groove, locking pin pin enters in the self-locking grooves on poke rod axle sidewall, the maloperation that External Force Acting causes can be avoided like this, play safety protection function, when handle set needs operation, poke rod axle entirety is moved right to locking pin to deviate from from self-locking grooves poke rod axle, the rotation of handle set can be realized, when poke rod axle moves to desired location, location is realized by locking ball by Compress Spring two.
The utility model structure is simple, and easy to operate, the maloperation that lathe axis class handle can be avoided to cause due to External Force Acting, improves the security of lathe work.
Accompanying drawing explanation
Fig. 1 is that the utility model structure is bowed sectional view.
