Abstract
The invention discloses a columnar workpiece side opening tapping jig. The columnar workpiece side opening tapping jig comprises a jig body and an upper cover which is arranged on the jig body. The upper surface of the jig body is horizontally provided with a first workpiece groove with a half-round cross section, and the lower surface of the upper cover is horizontally provided with a second workpiece groove which is the same with the first workpiece groove in cross section shape and cross section size. The upper cover is further provided with a tapping hole which is communicated with the second workpiece groove. When the jig body and the upper cover are combined, the second workpiece groove is located over the first workpiece groove. When the jig body and the upper cover are combined, the second workpiece groove and the first workpiece groove form a sealed columnar space, a workpiece is placed inside the columnar space and then is located, and then a screw tap or a thread tap is used and penetrates through a tapping hole to conduct tapping on the workpiece. Therefore, the workpiece is precisely located and standard inner threads are easily obtained.
Description
Technical field
The present invention relates to a kind of machined tool, especially a kind of tapping tool that is applied to cylindricality workpiece side opening.
Background technology
Tapping is a kind of process for machining, specifically refers to process internal thread in ready-made hole.The instrument of tapping is called screw tap or screw tap usually, in the process of tapping, place level or vertical position in order to make the screwed hole center line, not only the positioning requirements to workpiece is very high, and the position of screw tap or screw tap just need be put, this has just proposed higher requirement to the tool of tapping.Especially the cylindricality side surface of workpiece is being carried out in the tapping process, because its side is the face of cylinder, thereby the more difficult location of workpiece.
Summary of the invention
The technical problem to be solved in the present invention is the instrument that a kind of location is provided to the side tapping of cylindricality workpiece.
For addressing the above problem, the invention provides a kind of columnar workpiece side opening tapping tool, the loam cake that comprises the tool main body and be arranged on described tool main body top, it is characterized in that: it is the semicircular first workpiece groove that described tool main body upper surface level is provided with a cross section, the lower surface level of described loam cake is provided with a cross sectional shape and the size second workpiece groove identical with the described first workpiece groove, cover on described and also be provided with the tapping hole that is communicated with the described second workpiece groove, during the combination of described tool main body and described loam cake, the described second workpiece groove be positioned at the described first workpiece groove directly over.
As a further improvement on the present invention, also comprise fixture with described loam cake and the detachable combination of described tool main body.
As a further improvement on the present invention, described fixture is screw rod and nut, and described screw rod is fixedly connected on the described tool main body, covers to be provided with on described and holds the through hole that described screw rod passes, described nut and described screw rod are when being threaded, and described nut is positioned at the top of described loam cake.
As a further improvement on the present invention, described tool main body and loam cake are square.
As a further improvement on the present invention, described screw rod is four, and along the top that circumferentially is distributed on described tool main body.
As a further improvement on the present invention, be provided with packing ring between described nut and described loam cake.
As a further improvement on the present invention, described tapping hole is vertical with the described first workpiece groove or the second workpiece groove.
Beneficial effect of the present invention is, when tool main body and loam cake combination, the second workpiece groove and the first workpiece groove form the cylindrical space of a sealing, workpiece is placed this cylindrical space, realization is to the location of workpiece, re-use screw tap or screw tap and pass the tapping hole workpiece is carried out tapping, because workpiece obtains accurate in locating, so the easier internal thread that obtains standard.
Description of drawings
Fig. 1 is structural representation of the present invention.
Wherein: 2-tool main body; The 4-screw rod; The 6-first workpiece groove; The 10-second workpiece groove; The 12-loam cake; 14-tapping hole; The 16-nut; The 18-through hole.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further details.
As shown in Figure 1, the loam cake 12 that the present invention includes tool main body 2 and be arranged on tool main body 2 tops, it is the semicircular first workpiece groove 6 that tool main body 2 upper surface levels are provided with a cross section, the lower surface level of loam cake 12 is provided with a cross sectional shape and the size second workpiece groove 10 identical with the first workpiece groove 6, also be provided with the tapping hole 14 that is communicated with the second workpiece groove 10 on the loam cake 12, tool main body 2 is during with loam cake 12 combinations, the second workpiece groove 10 be positioned at the first workpiece groove 6 directly over.When tool main body 2 makes up with loam cake 12, the second workpiece groove 10 and the first workpiece groove 6 form the cylindrical space of a sealing, workpiece is placed this cylindrical space, realization is to the location of workpiece, re-using screw tap or screw tap passes the 14 pairs of workpiece in tapping hole and carries out tapping, because workpiece obtains accurate in locating, so the easier internal thread that obtains standard.
Further, also comprise loam cake 12 fixture with the 2 detachable combinations of tool main body, when loam cake 12 and tool main body 2 by fixing device combination and when fastening, with clamping work pieces, prevent that it is loosening; When loam cake 12 and tool main body 2 are separated by fixture, be convenient to remove or from new installation workpiece.
Further, in the present invention, fixture is screw rod 4 and nut 16, and screw rod 4 is fixedly connected on the tool main body 2, and loam cake 12 is provided with and holds the through hole 18 that screw rod 4 passes, and nut 16 and screw rod 4 are when being threaded, and nut 16 is positioned at the top of loam cake 12.By being threaded, fastening convenient with dismounting.
Further, tool main body 2 and loam cake 12 are square, and screw rod 4 is four, and along the top that circumferentially is distributed on tool main body 2.Make when tool main body 2 and loam cake 12 combinations are fastening, stressed more even.
Further, 12 of nut 16 and loam cakes are provided with packing ring, increase lifting surface area, prevent from damaging by pressure loam cake 12.
Further, tapping hole 14 is vertical with the first workpiece groove 6 or the second workpiece groove 10.Guarantee the threaded line level of the internal thread that tapping obtains.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine technical scope according to the claim scope.
