Abstract
The utility model aims to provide a novel concave threading die and convex buckle threading die box assembly, change the conventional positioning structure or positioning mode of a threading die in a threading die box, increase contact area, make contact firm and effectively guarantee processing stability of the threading die. In the operation process, the threading die is put into the threading die box, a concave groove on the excircle of the threading die is aligned with a convex buckle on the threading die box, so that the concave groove and the convex buckle are aligned and buckled with each other. After the threading die is determined to be totally contacted with the threading die box, a cover top is connected with an outer diameter screw thread of the threading die box by an inner diameter screw thread so as to be screwed down. The circumferential surface of the cover top is additionally provided with knurling so as to increase friction in the rotating process. An external screw thread of a handle rod is in matching connection with an internal screw thread on the circumferential surface of the threading die box. An operator can operate by rotating the handle rod so as to process screw threads of parts.
Description
Technical field
The utility model belongs to field of machining, is specifically related to a kind of screwing tool, more specifically relates to a kind of screw die case assembly supporting with it when the matrix formula screw die that uses in the processing of pincers bed is made the screw external screw thread that is applicable to.
Background technology
Matrix formula screw die adopts new location structure and locate mode, is about to the original traditional screw and the way of contact of screw die pit and changes system into more firm concavo-convex mosaic mode, and the result of use of matrix formula screw die is fully played.The threaded exterior that processes by novel matrix formula screw die has brightness.Can residually not pull on the screw external threaded surface, the vestige of plucking, reach the requirement of screw thread design strength.
Also not having at present can matching used with it screw die box.If screw die and screw die box are combined into one, just can easily make external screw thread by manual operations, the process advantage of performance matrix formula screw die, that just can effectively solve this practical problem.
The utility model content
The purpose of the utility model patent is to provide a kind of new matrix formula screw die and convex button screw die case assembly, change conventional location structure or the locate mode of screw die in the screw die box, increase contact area, contact firmly guarantees that effectively screw die adds the stability in man-hour.
Described screw die case assembly comprises matrix formula screw die, protruding button screw die box, packing ring, caping, handle, described matrix formula screw die is put into protruding button screw die box, the convex of screw die box inner chamber buckle with screw die on concave groove match, the convex of screw die box is buckled and the concave groove of screw die is a matched in clearance, and the gap is 0.30-0.50mm.Screw die box one end cylindrical adds the system external screw thread, described caping machining internal thread, and the cylindrical of protruding button screw die box holds threading to match with the caping internal thread Monday.Processing one cannelure in the described caping is placed packing ring in the cannelure, guarantee that after caping is screwing packing ring contacts with screw die, makes screw die fixing in the screw die box, on-slip.On the outer circumference surface of described protruding button screw die box, establish two symmetrical internal thread holes, an end of described handlebar is processed into external screw thread, and it matches with internal thread hole on the screw die box periphery.Two symmetrical internal thread holes offering on the periphery by external screw thread on the handlebar and screw die box are connected, and the externally threaded length of handlebar is less than screw die box internal thread length 2-4mm.Be processed with the annular knurl line on the surface of described handlebar, the frictional force during with the increase handle, the annular knurl line is straight burr or reticulate pattern.
During operation, screw die is put into the screw die box, the convex that the concave groove on the screw die cylindrical is aimed on the screw die box is buckled, and makes it mutual aligning, goes into button.After confirming contact fully, caping connects mutually by the outer-diameter threads of internal diameter whorl screw thread with the screw die box, gets rid of tightly to get final product.The caping circumferential surface adds system annular knurl line, the frictional force when rotating to increase.Be connected between the internal thread on handlebar external screw thread and the screw die box periphery, operating personnel can be undertaken by the rotary handle bar, come the screw thread of processing parts with this.
Chimeric by concave-convex type, no matter being contact area or contact strength comes reliably than original way of contact of withstanding the circular pit on the screw die cylindrical end face with holding screw.And this way of contact has also thoroughly solved screw die " rotation " phenomenon.So both be convenient to processing, be convenient to practical operation again.Need not to change operating habit.
The utility model can be widely used in mechanical manufacturing field, as: space flight, automobile, printing machinery, micro-machine etc.
Below in conjunction with drawings and Examples the utility model is elaborated, as is known to the person skilled in the art, the drawings and specific embodiments do not constitute restriction of the present utility model.
