Description
Technical field
The utility model relates to machine tool field, specifically a kind of operation self-locking limit position-limit mechanism.
Background technology
lathe is the important production equipment for processing equipment parts in modern industry, in national modernization construction, play important effect.In lathe often there is the problem of maloperation in handle, there is certain potential safety hazard when lathe is worked.
utility model contentthe purpose of this utility model is to provide a kind of operation self-locking limit position-limit mechanism, there is the problem of potential safety hazard to solve prior art lathe due to the maloperation of axle class handle.
In order to achieve the above object, the technical scheme that the utility model adopts is:
Operation self-locking limit position-limit mechanism, it is characterized in that: include handle set, handle, axis hole is provided with on rear side of handle set, described handle front end is connected with Handle axis, and handle front end Handle axis to be rotatably installed on rear side of handle set in axis hole, and matched in clearance between Handle axis and axis hole, the stopper slot being provided with on the left of axis hole and being communicated with axis hole is positioned in handle set, the spring groove being provided with on the right side of axis hole and being communicated with axis hole is positioned in handle set, the spring extended in left-right direction is connected with in spring groove, described spring left end stretches in axis hole, and spring left end is connected with limit spacer pin, described Handle axis is provided with the pin-and-hole that can enter for limit spacer pin pin.
Described operation self-locking limit position-limit mechanism, is characterized in that: described spring left end is connected with Connection Block, Connection Block is connected with limit spacer pin.
In the utility model, during handle inoperation, spring is utilized to drive spacer pin to push in stopper slot by Handle axis, make handle locked in stopper slot, thus can effectively avoid maloperation problem, when needing operating grip, Handle axis is exited from stopper slot, easy to use, substantially increase the security of lathe handle.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
