Abstract
The utility model provides an elastic sleeve of a drill chuck and belongs to the field of mechanical technology, which solves the problem of low operational stability in the prior art. The ring-shaped elastic sleeve of the drill chuck is arranged at the upper end of a drill chuck main body and circumferentially fixed with the drill chuck body; a plurality of convex bodies are arranged outside the elastic sleeve; a drill can be conveniently arranged on the drill chuck when necessary only by directly moving the elastic sleeve by hands of an operator to ensure the elastic sleeve to drive the body to rotate; as the convex bodies are arranged outside the elastic sleeve, larger friction force exists between the elastic sleeve and the hands of the operator in the operational process, so as to bring convenience for the move of the elastic sleeve. The elastic sleeve of the drill chuck is high in safety and convenient in rotation.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of elastic cover of the drill chuck that is used for the clamping drill bit, particularly drill chuck.
Background technology
Bench drill is widely used in machining, in order to process different workpiece, often needs to change different drill bits.
Drill chuck is exactly to be used for easy, quick more a kind of device of bit change, and existing drill chuck has two types usually: spanner drill chuck and self-tightening drill chuck.Spanner drill chuck is clamping or pine need be used aid when unloading drill bit, and operation seems more loaded down with trivial details.And self-tightening drill chuck has just overcome the problems referred to above, and it loads and unloads drill bit by the elastic cover that circumferentially is connected in the drill chuck main body.Only need rotate elastic cover with hand and get final product when operation, it seems easier in operation.
Rotation elastic cover for convenience, existing drill chuck are provided with the lines that protrudes slightly in the outside of elastic cover, after operator's hand contacts this lines, can increase frictional force, thereby be convenient to rotate elastic cover.But because lines and the frictional force between operator's hand on the elastic cover are limited, particularly when the rotation of drill chuck main body was smooth, the operator possibly can't rotate elastic cover.Finally just make drill chuck can't load and unload drill bit normally.
Summary of the invention
The purpose of this utility model is to exist the not high problem of stability in use at existing, and a kind of elastic cover of drill chuck is provided.
The purpose of this utility model can realize by following technical proposal: a kind of elastic cover of drill chuck, it is circular that elastic cover is, elastic cover is enclosed within the upper end of drill chuck main body and circumferentially fixing with the drill chuck main body, its feature in, the described elastic cover outside is provided with the convex body of several protrusions.
In the time of need being loaded and unloaded on drill bit on the drill chuck, the operator directly pulls elastic cover with hand, and elastic cover drives and can load and unload drill bit easily after main body is rotated.Because the outside of elastic cover has the convex body of protrusion, therefore, the frictional force in operating process between convex body and the operator's hand is bigger, thereby can pull elastic cover easily.
In the elastic cover of above-mentioned drill chuck, described convex body and elastic cover are connected as a single entity.Such structure is used more convenient.
In the elastic cover of above-mentioned drill chuck, described convex body is uniformly distributed in the elastic cover outside.
In the elastic cover of above-mentioned drill chuck, described convex body top is circular-arc, and the junction of convex body and elastic cover is an arc transition.Such structure just makes whole elastic cover be quincunx, and obviously, but the operation person can rotate the elastic cover of this shape easily.
In the elastic cover of above-mentioned drill chuck, described elastic cover is connected with the drill chuck main body by spline.Elastic cover and drill chuck main body circumferentially can be fixed by such structure.
As another kind of situation, in the elastic cover of above-mentioned drill chuck, the side on described drill chuck main body top has at least one plane, and above-mentioned elastic cover is inboard to be complementary with drill chuck main body shaped upper part.As can be seen, can make drill chuck main body and elastic cover circumferentially fixing firmly equally by such structure.
Compared with prior art, the elastic cover of this drill chuck is because the size of convex body is bigger, and correspondingly, the frictional force between operator's hand and the convex body is also just bigger.Therefore, when operation, elastic cover is rotated.
Simultaneously, the circular shape of convex body makes that also in pulling process, operator's hand is difficult for injured.Therefore, its safety in utilization is higher.

The specific embodiment
Embodiment one
As shown in Figure 1, drill chuck is installed on the bench drill, and it is used to load and unload drill bit.
As shown in Figure 2, the elastic cover of this drill chuck is circular, and it is enclosed within on the drill chuck main body 2.Elastic cover 1 is circumferentially fixing by spline and drill chuck main body 2.
Elastic cover 1 is quincunx, and its outside has the plush copper 3 of 12 protrusions, and plush copper 3 evenly distributes and plush copper 3 is connected as a single entity with elastic cover 1.In the present embodiment, the top of plush copper 3 is circular-arc, and the junction of it and elastic cover 1 is an arc transition.
When needing clamping or pine to unload drill bit, the operator can directly pull elastic cover 1 with hand, just can drive elastic cover 1 by the frictional force between elastic cover 1 plush copper 3 and the operator's hand rotates, drill chuck main body 2 so just can be contained in drill bit on the drill chuck or with drill bit and unload also along with rotation in elastic cover 1 rotation process.
Embodiment two
Present embodiment is basic identical with structure and the principle of embodiment one, and different place is that the two sides on drill chuck main body 2 tops all have a plane, and elastic cover 1 inboard is complementary with drill chuck main body 2 shaped upper parts, sees shown in Figure 3.After elastic cover 1 was enclosed within the top of drill chuck main body 2, elastic cover 1 had just circumferentially been fixed firmly with drill chuck main body 2.That is to say that drill chuck main body 2 can be along with together rotating when rotating elastic cover 1.
