Description
Technical Field
The utility model relates to a guiding orientation device for screw tapping.
Background
The bolt connection is a common structural form in process equipment, and when parts are machined, a threaded bottom hole is firstly machined and then manual tapping is carried out, so that the bolt connection is the most common machining mode in a workshop at present. When the axis of the screw hole is vertical to the surface of the workpiece, an operator needs to arrange the center line of the screw hole at a horizontal or vertical position during manual tapping, so that whether the axis of the screw tap is vertical to the plane of the workpiece or not can be easily judged during tapping. The tap is placed in a correct mode when tapping is started, then the tap is stressed and the twisting hand is rotated, the position of the tap is carefully checked and corrected when 1-2 circles of tapping are cut, the axis of the tap is perpendicular to the plane of a workpiece, and generally 3-4 circles of tapping are cut, the position of the tap is correct. Only then need to rotate the drift holder, should not again exert pressure to the tap, otherwise the screw thread profile will be destroyed.
However, in the actual operation process, due to the influence of factors such as visual judgment errors, the placement state of parts, the technical level of a fitter, large hand inclination or shaking amplitude in the tapping process and the like, the axis of the screw tap is not perpendicular to the surface of a workpiece, so that the screw hole is inclined, the screw tap is damaged or broken, when the screw tap is connected with a matched part, the bolt cannot be inserted into the screw hole, the part is reworked, and the part is possibly scrapped seriously; in addition, when screw quantity is more, process time and cost can greatly increased, in addition, when screw axis and workpiece surface area angle, can only realize through machining, manual tapping can't guarantee, consequently, seek a neotype screw tap guiding orientation device and have important realistic meaning in order to improve manual tapping machining efficiency and practice thrift the processing cost.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a guiding orientation device for screw tapping.
The utility model provides a technical scheme of above-mentioned problem is:
the utility model provides a guiding orientation device for screw tapping, includes direction base, quick change bush, location bolt and holding screw, still includes the magnetism gauge stand that adsorbs the fixed together of direction base and the work piece of treating the tapping, be equipped with a drill bushing hole and a drill bushing compress tightly the hole on the direction base, quick change bush and drill bushing hole cooperation pass the drill bushing through holding screw and compress tightly the hole location, and the location bolt is inserted and is located in the quick change bush, and the specification of quick change bush and location bolt is decided according to the specification of the screw of treating the tapping.
Further, the thickness of the guide base is smaller than the length of the positioning bolt.
The utility model discloses simple to use, the structure is reliable, and the screw location is accurate convenient, can realize the quick location of screw tap, has guaranteed the processingquality of screw, has improved the machining efficiency of manual tapping greatly, practices thrift the processing cost, has shortened processing cycle and has practiced thrift manufacturing cost.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Further, the thickness of the guide base 5 is smaller than the length of the positioning pin 3.
The positioning bolt 3 of the utility model is used for positioning the guide base 5, in order to adapt to the tapping of screw holes with different specifications, the quick-change bush and the positioning bolt are correspondingly matched according to the specifications of common screw holes, when in work, as shown in figure 5, firstly, the corresponding quick-change bush and the positioning bolt 3 are selected according to the specifications of the screw holes to be tapped, the quick-change bush 4 is installed in a drill bushing hole of a guide base hole, after the guide base 5 is aligned with a bottom hole of a screw thread to be tapped by utilizing the positioning bolt 3, the guide base 5 and a workpiece 6 to be tapped are adsorbed and fixed together by utilizing the magnet gauge stand 1, the positioning bolt is pulled out, then, the screw tap 7 is sleeved in the quick-change bush, the tapping work can be easily and standardly completed by utilizing the linear guiding effect of the quick-change drill bushing, only the wrench 8 needs to rotate without pressurizing the screw tap, the screw tap is effectively prevented from being damaged, especially, the work efficiency of workers can be greatly improved when the workpiece is suspended and the surface of the workpiece has an angle. And the device is light and portable, is simple and convenient to operate, and is widely suitable for field operation occasions.
In order to adapt to tapping of screw bottom holes of different specifications such as M5, M6, M8, M10, M12 and M16, wherein the inner hole of the guide base is phi 16H7, the quick-change bushings are provided with specifications such as 5 × 16g6 × 14, 6 × 16g6 × 14, 8 × 16g6 × 14, 10 × 16g6 × 14 and 12 × 16g6 × 14, and the corresponding positioning pins are provided with specifications such as phi 5/phi 4.2, phi 6/phi 5, phi 8/phi 6.8, phi 10/phi 8.5 and phi 12/phi 10.5.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
