Abstract
The utility model relates to a miniature mounting and dismounting fixture, which is characterized in that the miniature mounting and dismounting fixture is provided with a body and a clamping mechanism, the clamping mechanism comprises an outer casing, a fixed sleeve, steel balls and a torsion spring, wherein the steel balls are arranged in a radial pore of an end portion of the body, the fixed sleeve is fixed in the middle of the body, the outer casing is covered on the outer circle of the end portion of the body, and the torsion spring is arranged between the outer casing and the fixed sleeve. The miniature mounting and dismounting fixture is further provided with an ejecting mechanism which is equipped with a spring, a positioning block and a choke plug, wherein the positioning block is arranged in the middle of the body, the spring is sleeved on the positioning block, and the choke plug is arranged at a head portion of the body. Besides, the inner end diameter of the radial pore is smaller than the diameter of the steel balls. The utility model has simple structure and fine using effect. Torsion force generated by the torsion spring limits and clamps the tool via the outer casing, and steps on different radiuses on an inner bore groove of the outer casing have anti-loose function under stress.
Description
Technical field:
The utility model relates to the miniature loading and unloading clamp that loads and unloads cutter in a kind of machining fast, is mainly used in the fixing of positioning handle, and is applicable to power drill.
Background technology:
On the market a kind of professional drill bit---Steel Plate Guide Drill is arranged now, but can only be on specialized apparatus, or carry out operation on the legacy equipment.Opened greatly at this product and on little cutting-in, specification, can utilize handheld device that steel plate is carried out hole processing miniature steel plate to bore.The anchor clamps that have some to connect handheld device and miniature steel plate brill in the market, but adopt screw to connect more, service efficiency is low, and is convenient inadequately.
Summary of the invention:
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of clamp cylinders surface that is used for that the miniature loading and unloading clamp of uniform two holes or three hole groove positioning handles is arranged.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this miniature loading and unloading clamp, it is characterized in that being provided with main body, clamp mechanism, main body is used for transmission power, clamp mechanism comprises overcoat, fixed cover, steel ball, torsion spring, clamp mechanism is used for the clamping of positioning handle, fixed cover is fixed on the centre of main body, overcoat is enclosed within on the body end cylindrical, can rotate around main body, be connected with torsion spring between overcoat and the fixed cover, make outer be with clockwise or change counterclockwise apply torsion, steel ball moves radially certain distance in main body near the Kong Zhongke of end, overcoat endoporus groove is that different radius arc connects and constitutes.Steel ball protrudes in outer round surface, also just form the torsion rotating jacket of answering torsion spring to produce, overcoat is contacted with steel ball on little overcoat radius arc, the restriction steel ball radially outward moves, this moment, steel ball was higher than bore area, just can produce two restrictions to grip shank: limit rotation and move axially restriction.The torsion that overcomes torsion spring when external force makes overcoat to anticlockwise, and steel ball just can move radially certain distance, and this moment, steel ball was lower than bore area, unclamped positioning handle.
The utility model also can be provided with material jacking mechanism, and material jacking mechanism is provided with spring, locating piece, silently, and locating piece is arranged in the middle of the main body, and spring housing silently is arranged on body head on locating piece.
The inner aperture of radial hole described in the utility model is less than diameter of the steel ball.
The utility model fixed cover is fixed on the centre of main body by screw, is adopted diameter less than 13mm and there is trisection flat by the design of the ansa of clamping, meets the method for clamping of power drill.
The utility model is simple in structure, result of use good, and the torsion that torsion spring produced is used for restriction and clamping tool by overcoat, and the step on the overcoat endoporus groove on the different radii plays the effect that does not come loose when stressed.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the schematic diagram under the utility model embodiment steel ball clamped condition.
Fig. 3 is the schematic diagram under the utility model embodiment steel ball releasing orientation.
The specific embodiment:
Referring to Fig. 1～Fig. 3, the miniature loading and unloading clamp of the utility model embodiment is provided with main body 2, clamp mechanism, main body 2 is used for transmission power, clamp mechanism comprises overcoat 8, fixed cover 4, steel ball 7, torsion spring 6, screw 5, clamp mechanism is used for the clamping of special-purpose handle (location, two holes or three hole positioning handles), fixed cover 4 is fixed on the centre of main body 2 by screw 5, overcoat 8 is enclosed within on the main body 2 end cylindricals, can rotate around main body 2, be connected with torsion spring 6 between overcoat 8 and the fixed cover 4, make overcoat 8 that the torsion that applies of clockwise commentaries on classics be arranged, steel ball 7 is in the radial hole 11 of main body 2, radial hole 11 inner apertures are less than steel ball 7 diameters, restriction steel ball 7 drops out from radial hole 11, and overcoat 8 endoporus have the groove 10 of corresponding steel ball 7, and groove 10 is provided with the circular arc of different-diameter, the radial hole 11 of steel ball 7 stressing mains 2, the steel ball 7 of stressing main 2 is positioned at the groove 10 of overcoat 8.By the torsion rotating jacket 8 that torsion spring 6 is produced, make steel ball 7 contact on the medium and small radius arc of groove 10, make steel ball 7 protrude in the endoporus of main body 2, this moment, overcoat 8 limited radially moving outward of steel ball 7, and Fig. 2 has shown that steel ball 7 is in the schematic diagram of clamped condition.The torsion that overcomes torsion spring 6 when external force makes overcoat 4 to anticlockwise, and steel ball 7 can move radially when rotating to certain position, and steel ball 7 outwards moves under the promotion of positioning handle, and Fig. 3 has shown that steel ball 7 is in the schematic diagram of releasing orientation.
The utility model embodiment also can be provided with material jacking mechanism, material jacking mechanism comprises silently 1, spring 3, locating piece 12, locating piece 12 is arranged in the middle of the main body 2, spring 3 is enclosed within on the locating piece, silently be arranged on main body 2 heads, the effect that utilizes spring force is to silently 1 producing a kind of power to clamping handle direction end.Thimble in the middle of being used in use miniature steel plate being bored produces the power on top, thereby plays the effect of liftout.
The utility model embodiment can be designed to overcoat 8 according to actual needs and turned clockwise by the active force of torsion spring 6 to clamp or be rotated counterclockwise to clamp steel ball 7, and correspondingly adjusts the torsion direction of torsion spring 6 and the arc position of overcoat 8 endoporus groove different-diameters.
The overcoat 8 endoporus grooves of the utility model embodiment also can be other forms of plane or curved surface, as relative plane etc.The simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought to fall into protection domain of the present utility model.
