Abstract
The utility model relates to the field of part turning using lathes, in particular to a safety chuck key tool post wrench. The wrench comprises a lever, a spring, a tool post wrench sheath and a chuck key, wherein the lever is vertically connected with the chuck key; the tool post wrench sheath is sheathed on the chuck key; and a spring protection device is arranged between the lever and the tool post wrench sheath. The wrench has the functions of the chuck key and the tool post wrench, and has the advantages of convenient use, obviation of one common lever for two products, low material consumption, and improvement on safety. In addition, the spring protection device can achieve more humanized design effect.
Description
Technical field
The utility model relates to use lathe turning part field, especially a kind of safety chuck key tool-post wrench.
Background technology
In using lathe turning part process, the frequency of utilization of chuck key and tool-post wrench is very high, employed in the past such product function is single relatively, influence the raising of production efficiency, employed in the past chuck key and tool-post wrench are standalone tool, respectively carry boosting-rod, so waste material is not energy-conservation.Need select corresponding tool for use at different objects during use, then need select tool-post wrench for use when the knife rest nut being carried out degree of tightness, then need select the chuck key for use when if desired chuck being carried out degree of tightness as need, more time-consuming.Simultaneously, originally employed chuck key is pulled up owing to the operator forgets through regular meeting, and causes the generation of accident.
The utility model content
Use inconvenience in order to overcome existing chuck key and tool-post wrench, accident-prone deficiency, the utility model provides a kind of safety chuck key tool-post wrench.
The technical scheme that its technical problem that solves the utility model adopts is:. a kind of safety chuck key tool-post wrench; comprise boosting-rod, tool-post wrench cover and chuck key; boosting-rod is connected chuck on the key; the chuck key is combined with cover tool-post wrench cover, increases the spring protection device between boosting-rod and the tool-post wrench cover.
According to another embodiment of the present utility model, comprise that further chuck key top is a quadrangular, tool-post wrench cover top is an internal square hole.
According to another embodiment of the present utility model, comprise that further boosting-rod vertically is inserted in the hole of chuck key tip.
According to another embodiment of the present utility model, comprise that further the tool-post wrench cover is enclosed within the chuck key, be fixed on chuck screw screens on the key by one, can in certain interval, move up and down.
According to another embodiment of the present utility model, further comprise spring housing on the key at chuck, be limited between boosting-rod and the tool-post wrench cover.
The beneficial effects of the utility model are, the one, chuck key and tool-post wrench are united two into one, and play the effect that a product produces two kinds of functions, no matter be to chuck or the knife rest nut carried out degree of tightness can both finish smoothly.Two part one boosting-rods that product is public before dispensing simultaneously; promptly save material; the 2nd, increased security; consider that promptly the operator may forget the accident of taking out the chuck key and causing behind clamping work pieces; set up the spring protection device; after the chuck degree of tightness is finished; because the elastic pressure of spring puts on the tool-post wrench cover; under the effect of reaction force; the keyhole that makes the chuck key withdraw from chuck automatically is withdrawn in the tool-post wrench cover, plays the design effect of safer protection and hommization.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the schematic diagram of chuck key;
Fig. 3 is the schematic diagram of tool-post wrench cover;
1. boosting-rods among the figure, 2. tool-post wrench cover, 3. chuck key, 4. spring.
With preferred embodiment the utility model is described in further detail by reference to the accompanying drawings now. These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Structural representation of the present utility model such as Fig. 1, a kind of safety chuck key tool post wrench, comprise boosting-rod 1, tool-post wrench cover 2, chuck key 3 and spring 4, boosting-rod 1 vertically is inserted in the hole of chuck key 3 ends, can be elastic to adjust moment or convenient the use, chuck key 3 tops are quadrangular, and it is internal square hole that tool-post wrench overlaps 2 tops. Tool-post wrench cover 2 is enclosed within on the chuck key 3, by a screw screens that is fixed on the chuck key 3, can move up and down in certain interval. Spring 4 is enclosed within on the chuck key 3, is limited between boosting-rod 1 and the tool-post wrench cover 2.
The specific embodiment
The operator is in the process of using this product, only need hold boosting-rod 1 gets final product, when the knife rest nut being carried out degree of tightness as need, directly be enclosed within to rotate on the knife rest nut and get final product, the clamping force of nut is the internal square hole that passes to tool-post wrench cover 2 of the quadrangular by chuck key 3, so the torque ratio of transmitting is bigger, can satisfy instructions for use fully, when if desired chuck being carried out degree of tightness, the keyhole of then can be directly chuck being aimed on chuck key 3 tops gets final product, and four jiaos of keys will expose automatically and carry out work, and its moment of torsion will directly be transmitted by boosting-rod 1, if the operator forgets the instrument of pulling up, then chuck key 3 can be owing to the effect of spring force, and keyhole is withdrawed from the key top automatically, and the cover the inside, four directions that is withdrawn into tool-post wrench cover 2 is gone, thereby assurance safety implements more convenient.With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
