Abstract
The utility model discloses a centering clamping jaw of a drill chuck as well as the drill chuck comprising the centering clamping jaw. A clamping surface of a clamping jaw body (1) is depressed inwards to form a clamping groove (2). In the centering clamping jaw of the drill chuck as well as the drill chuck comprising the centering clamping jaw, the clamping surface of the clamping jaw body is provided with the clamping groove so as to avoid the problem of slippage between the clamping jaw and a tool in the traditional clamping manner, and two crossing surfaces are axially symmetrical along the intersection line so as to thoroughly eliminate the problem of slippage between the clamping jaw and a handle tool; the centering clamping jaw of the drill chuck as well as the drill chuck comprising the centering clamping claw can be used as a common tool and have wider applicability; and a stud is matched with the drill chuck so as to realize the unscrewing and screwing of an internal thread angle nut as well as the use of regular internal thread angles and irregular internal thread angles and realize the function of a screw driver within a narrow space range.
Description
Technical field
The parts that the utility model relates to a kind of drill chuck with and the instrument that constitutes, specifically be meant a kind of centering jaw of drill chuck and the drill chuck of formation thereof.
Background technology
In modern industry production, life, electric drill, electric hammer are the instruments of using always, and electric drill, electric hammer are subjected to liking of people because of advantages such as volume are little, easy to carry, of many uses.The operation principle of electric drill, electric hammer is to utilize the rotation of motor to drive brill flower or reamer etc., by the adjusting ring on the rotary drilling chuck, the brill flower of a series of sizes can be installed in drill chuck, satisfies different client's needs with this.But present electric drill, electric hammer all have a fatal shortcoming, and that is exactly for the nut of abnormity or inner nut, present electric drill still can not at use, make the use of electric drill be restricted.
The utility model content
The purpose of this utility model provides a kind of centering jaw of drill chuck and the drill chuck and the kit of formation thereof, overcomes the phenomenon that the clamping handle kind tool skids easily, is used for increasing the scope of application of electric drill simultaneously, solves inner nut and is difficult to the problem tightening, dismantle.
The purpose of this utility model is achieved through the following technical solutions:
A kind of centering jaw of drill chuck comprises the jaw body, the clamping face of the jaw body formation clip slot that caves inward.The contact-making surface that the mode that clamping face by the jaw body is provided with clip slot has increased the handle of clamping face and handle class clamping device connects, the clamping that has changed traditional jaw and handle relies on and increases the radially mode of chucking power, has eliminated the phenomenon that jaw body and handle skid.
Described clip slot constitutes by two faces are crossing, and its dihedral angle is β.
Two faces of described clip slot become axial symmetry along its intersecting lens.For the handle that corner angle are arranged, by the mode of the clip slot with corner angle is set on the jaw body, make the corner angle of all jaw bodies constitute the mode of the cavity that the corner angle with handle are complementary, thoroughly eliminated the handle problem of slip.
A kind of drill chuck comprises the drill chuck body, and the jaw body is evenly distributed on the radially disc of drill chuck body as the described centering jaw of claim 1 to 2 to be equipped with n on the drill chuck body, and n is natural number and n 〉=3, β=360 ° ÷ n.For unconventional corner angle handle kind tool, can realize the corner angle clamping equally by the jaw body of varying number.
As a kind of corner angle commonly used, the number n of described centering jaw=3, β=120 °, by three clip slots that cross section is an isosceles triangle on 3 jaw bodies, the drift angle of isosceles triangle is 120 °, form orthohexagonal corner angle clamping cavity,, realize clamping the regular hexagon handle kind tool of a series of diameters by changing the distance that three jaw bodies directly make progress at the drill chuck body.
Also comprise the double-screw bolt that cavity that the clip slot with described n centering jaw constitutes is complementary.The instrument that drill chuck constitutes, comprise drill chuck, also comprise the double-screw bolt that cavity that the clip slot with n centering jaw constitutes is complementary, match mutually with the corner angle drill chuck that what use is double-screw bolt class instrument, with double-screw bolt class tool holding after on the drill chuck, can drive the rotation of double-screw bolt by the rotation of drill chuck, realize tightening and dismantling of internal spiral shell angle class nut.
The number n of described centering jaw=3, the cross section of double-screw bolt are regular hexagon.Common interior spiral shell angle nut is interior hexagonal (hexagon)nut, and therefore, selecting the number n of centering jaw is 3, and the cross section of double-screw bolt is a regular hexagon, and the dismounting of interior hexagonal (hexagon)nut commonly used will no longer need professional tool.
As further improvement of the utility model, in order to increase the scope of application of drill chuck, an end of double-screw bolt is provided with the cutter head of screwdriver, makes it realize the effect of screwdriver in the space-constrained scope.
The utility model compared with prior art has following advantage and beneficial effect:
The centering jaw of a kind of drill chuck of 1 the utility model, the mode of clip slot is set by the clamping face at the jaw body, eliminated the problem of skidding of jaw and Tool Room in traditional method of clamping, clip slot is set to two phase cross surfaces along the axial symmetrical manner of intersection, has thoroughly eliminated the problem of skidding between jaw and the handle kind tool;
A kind of drill chuck of 2 the utility model, the mode that n the jaw of feeling relieved evenly is installed on the drill chuck body makes the variation of drill chuck working method, be applicable to unconventional instrument, the jaw of feeling relieved is set to 3, can be used as common instrument and uses, and applicability is wider;
A kind of drill chuck of 3 the utility model, by the double-screw bolt that is complementary with drill chuck, the dismounting that can realize internal spiral shell angle nut with tighten, realize the use with unconventional interior Luo Jiao, and can in the narrow space scope, realize the effect of screwdriver Luo Jiao in conventional.
