Detailed description of the invention
With reference to Fig. 2 to Fig. 5, hand tapping guider of the present utility model, comprises pedestal 1, fairlead 2 and magnet 3.Pedestal 1 is in cuboid, the surface of fitting with workpiece to be machined of pedestal 1 is provided with container cavity 10, and described magnet 3 is arranged in container cavity 10, and the height of described magnet 3 is less than or equal to the degree of depth of container cavity, by the adsorption of magnet 3, ensure that fairlead is vertical with the screw thread basal plane of workpiece.Also comprising locating piece 4, is that compartment of terrain is provided with the first support arm 5 and two support arm 6, first support arms 5 and two support arms 6 and extends along the length direction of pedestal 1 in one end of pedestal 1.Locating piece 4 is between the first support arm 5 and two support arms 6, and the two ends of locating piece 4 are hinged with the end of the first support arm 5 and the second support arm 6 respectively, and like this, locating piece 4 can rotate around pin joint.The end face of the workpiece to be machined laminating of locating piece 4 is provided with through hole 40, and through hole can be taper, can offer help to the raising of positioning precision, and described fairlead 2 is arranged in this through hole 40.The aperture of fairlead 2, can process the size of screw tap, change fairlead, namely select the fairlead 2 of concrete pore size according to difference, be decided by the screw tap of thread mill drilling.
First end face towards the first support arm 5 of locating piece 4 is provided with the first step 41 coordinated with the first support arm 5, second end face towards the second support arm 6 of locating piece 4 is provided with the second step 42 coordinated with the second support arm 6, after being provided with first step 41 and second step 42, the cross sectional shape of locating piece 4 is in " convex " font.When locating piece rotates around the pin joint with the first support arm 5 and the second support arm 6, the first support arm 5 pairs first step 41 forms position-limiting action, and the second support arm 6 pairs second step 42 forms position-limiting action.Like this, locating piece 4 is limited and rotates within the specific limits, and the rotation of 360 degree can not be carried out, in use, because locating piece 4 will be pushed down by the first support arm 5 and the second support arm 6, locating piece 4 can be avoided to overturn because of vibration, that is, the stability that locating piece 4 can be made to locate obtains and improves.
Between the first support arm 5 and first step 41, and between the second support arm 6 and second step 42, spring 7 is all installed.The concrete mounting means of spring 7 is, first support arm 5 and the second support arm 6 are provided with installing hole, first step 41 and second step 42 are provided with erection column 43, and one end of spring 7 is arranged in installing hole, and the other end of spring 7 to be enclosed within erection column 43 and to hold out against described locating piece 4.In order to more convenient to install, what erection column 43 adopted is screw.By the elastic force effect of spring 7, locating piece 4 is withstood, under non-working condition, locating piece 4 and define angle between the first support arm 5 and the second support arm 6, the size of this angle is 5 to 10 degree, because the first support arm 5 and the second support arm 6 are one with pedestal, and extend along pedestal length direction, therefore, after locating piece 4 and the first support arm 5 and the second support arm 6 define 5 to 10 angles of spending, also automatically make to form corresponding spacing distance between the locating surface of pedestal 1 workpiece to be machined, at the magnetic force that this spacing distance lower magnet sends, magnet adsorption can not be made on workpiece, namely this spacing distance avoid centering fairlead and workpiece want the position of tapping before, pedestal 1 is just made to position, then be difficult to the drawback at centering tapping center.
With reference to Fig. 6, the other end of pedestal 1 is provided with handle 8, and the end of the mounting handle of pedestal 1 is provided with groove, and handle 8 is arranged in this groove, and by bearing pin and pedestal hinged.When the utility model uses, by the center of fairlead and workpiece to be machined 9 want the position of tapping to align after, by turning handle 8, pedestal 1 is driven to overcome the elastic acting force of spring 7 under the surface pressure of workpiece, under the adsorption of magnet 3, be adsorbed on by pedestal 1 on the surface of workpiece 9, like this, pedestal 1 and locating piece 4 have all been fixed on workpiece to be machined 9.Because fairlead 2 and surface of the work maintain perpendicularity, therefore, after screw tap enters into fairlead 2, screw tap and workpiece also keep vertical, and screw tap enters after in fairlead 2, can carry out hand tapping.After tapping completes, by pulling handle 8 to overcome the magnetic adsorptive power of magnet 3, guider is made to depart from workpiece.
