Description
Technical field
The utility model relates to a kind of lathe accessories, particularly a kind ofly can be used for loading and unloading the lathe key that cutter can be operated the scroll chuck workpiece loading and unloading again.
Background technology
As everyone knows, all have two lathe keys on the lathe, wherein one being solid wrench, is used for rotating the scroll chuck workpiece loading and unloading, and another is dead sleeve, is used for loading and unloading cutting tool, and two keys are indispensable.But two lathe keys have the following disadvantages in actual use: the one, and operating grip comes off through regular meeting, falls in storage bits case, loses easily; The 2nd, when workpiece loading and unloading, individual operation personnel forget from scroll chuck sometimes and take down key, bring potential safety hazard to operation; The 3rd, put disheveled cleanly, deposit inconvenience; The 4th, function singleness can not be general.For this reason, many manufacturers and knowledgeable people develop and study at the problems referred to above, but do not find comparatively reasonably solution so far as yet.
Summary of the invention
For overcoming the above-mentioned disadvantage that existing lathe key exists, the purpose of this utility model provides a kind of simple and compact for structure, flexible and convenient operation, safe and reliable, lathe dual-purpose safe key that versatility is good.
The technical scheme that its technical problem that solves the utility model adopts, it comprises operating grip, connecting rod, spanner, outer sleeve, one end of connecting rod is provided with the installing hole of fitting operation handle, other end and spanner are connected as a single entity, be provided with continuous guide hole in the described outer sleeve successively, spanner telescopic hole and sleeve notch, on the afterbody sidewall of outer sleeve, be provided with relative slot, the connecting rod correspondence is arranged in the guide hole, spanner is arranged in the spanner telescopic hole and mutually and mates, operating grip is installed in the installing hole of connecting rod and stretches out sheathed spring on the connecting rod in the guide hole from two slots of outer sleeve.
Further preferred version of the present utility model, the aperture of described sleeve notch are convenient to spanner and are stretched out from the sleeve notch greater than the aperture of spanner telescopic hole.
Further preferred version of the present utility model, described spanner and sleeve notch are polygonized structure, can adapt to different requirements.
Further preferred version of the present utility model, described polygonized structure are equilateral triangle, square, orthohexagonal wherein a kind of.
After adopting said structure, the utility model has following advantage compared with the prior art: the one, can substitute the dead sleeve that is used for rotating the solid wrench of scroll chuck workpiece loading and unloading and is used for loading and unloading cutting tool, and spoonful dual-purpose; The 2nd, when key did not use, spring withstood on the operating grip, and operating grip can not deviate from from the installing hole of connecting rod, and good integrity is not easy to lose; The 3rd, when workpiece loading and unloading,, operating personnel take down key even forgetting from scroll chuck, drivening rod and spanner retraction under the spring force effect, key comes off from chuck automatically, has eliminated potential safety hazard; The 4th, key is combined into one from two, puts neatly, deposits conveniently, can effectively reduce cost; Have compact conformation, advantage such as easy and simple to handle, safe and reliable, effective.

The specific embodiment
Fig. 1 is to shown in Figure 4, specific embodiments for the utility model lathe dual-purpose safe key, it comprises operating grip 1, connecting rod 2, spanner 5, outer sleeve 3, one end of connecting rod 2 is provided with the installing hole 21 of fitting operation handle, other end and spanner 5 are connected as a single entity, be provided with continuous guide hole 32 successively in the described outer sleeve 3, spanner telescopic hole 33 and sleeve notch 34, the aperture of sleeve notch 34 and guide hole 32 is greater than the aperture of spanner telescopic hole 33, on the afterbody sidewall of outer sleeve 3, be provided with relative slot 31, connecting rod 2 correspondences are arranged in the guide hole 32, spanner 5 is arranged in the spanner telescopic hole 33 and mutually and mates, operating grip 1 is installed in the installing hole 21 of connecting rod and stretches out from two slots 31 of outer sleeve, sheathed spring 4 on the connecting rod 2 in the guide hole 32, spring 4 withstands on the operating grip 1 all the time.Described spanner 3 and sleeve notch 34 are polygonized structure, and this polygonized structure is equilateral triangle, square, orthohexagonal wherein a kind of preferably, and at present the most frequently used is square.
When the utility model is used to load and unload cutting tool, as shown in Figure 1, the sleeve notch 34 of outer sleeve 3 is entangled the clamp nut of cutting tool, pull operating grip 1 and can load and unload cutting tool.
When the utility model is used for the scroll chuck workpiece loading and unloading, hand-held operation handle 1, with force compresses spring 4, spanner 5 stretches out from sleeve notch 34, as shown in Figure 2, can utilize spanner 5 rotation scroll chuck workpiece loading and unloadings; After unclamping, spanner 5 resets under the effect of spring 4, retracts to automatically in the outer sleeve 3.
