Description
Technical field
The present invention relates to one to be applied to diameter and be less than M10 millimeter threaded hole, and this hole and outside screw have the frock of spiral shell cover processing that certain morpheme requires, screw thread frock and method thereof are attacked in the interior hole overlapped in particular to a kind of small-bore band outside screw steel spiral shell ensureing that internal and external threads morpheme requires.
Background technology
Some product structure adopts aluminum material, and the product place of being fastenedly connected need to constantly repeat dismounting, because aluminum material hardness is low, repeatedly repeats the damage that easy disassembling causes screw thread, thus greatly reduces the work-ing life of product. In order to overcome the above problems, generally join dress steel spiral shell cover at the place of being fastenedly connected of these products and solve. When Product Assembly accuracy requirement is higher (as: screw and outside screw concentricity are not more than �� 0.022 millimeter, and screw and outside screw precision are 6 grades), it is necessary to the spiral shell cover of special processing and manufacturing high precision. In order to the requirement of satisfied production in enormous quantities, this kind of spiral shell cover is generally completed by numerically-controlled machine, lathe in machining efficiency height, but disposable can not complete the processing of internal and external screw thread, need to machine for twice, owing to the benchmark of the processing of internal and external screw thread is inconsistent, particularly the processing of the internal thread that the spiral shell of high precision concentricity requirement overlaps can not being ensured, the problem of the requirement of concentricity is particularly outstanding.
Summary of the invention
Screw thread frock is attacked in the interior hole that the present invention provides a kind of small-bore band outside screw steel spiral shell cover, solves the technical problem that the processing of the internal thread that the spiral shell of high precision concentricity requirement overlaps can not be ensured concentricity by existing lathe.
The present invention solves above technical problem by the following technical programs:
Screw thread frock is attacked in the interior hole of a kind of small-bore band outside screw steel spiral shell cover, comprise platen, platen is provided with machine tool three-jaw chuck, platen is provided with support tube, the support tube periphery of support tube is connected in machine tool three-jaw chuck, the end face of support tube is fixedly installed round shape connected unit, the outer side wall of round shape connected unit is provided with round shape connected unit outside screw, the inner hole wall connecting cylinder is provided with and connects cylinder internal thread, together with the round shape connected unit external thread bolt connection that connection cylinder is arranged on the outer side wall of round shape connected unit by connecting cylinder internal thread, steel spiral shell cover inner hole thread tapping hole it is provided with in the hole of the connection cylinder of the top face of round shape connected unit, the outer side wall of steel spiral shell cover is provided with spiral shell cover outside screw, it is with externally threaded steel spiral shell cover to be screwed onto in steel spiral shell cover inner hole thread tapping hole, it is provided with in the surface of steel spiral shell cover and attacks chasing tool.
The bottom surface of steel spiral shell cover is that top is connected on the upper annular end face (9) of round shape connected unit, is bolted with and connects cylinder rotation handle on the outer side wall connecting cylinder.
A screw method is attacked in the interior hole of small-bore band outside screw steel spiral shell cover, comprises the following steps:
The support tube of the first step, processing belt round shape connected unit, tapping outside screw on the outer side wall of the round shape connected unit arranged in the center of top of support tube, the inner hole wall connecting cylinder is arranged and connects cylinder internal thread, the outer side wall connecting cylinder is arranged and connects cylinder rotation handle;
2nd step, connection cylinder is screwed in round shape connected unit, and rotates handle (screwed by connecting cylinder;
3rd step, by steel spiral shell cover by spiral shell overlap external thread bolt connection to connect cylinder top, interior hole in, and make steel spiral shell cover bottom surface top be connected on the upper annular end face of round shape connected unit;
4th step, by attack chasing tool extend into steel spiral shell cover interior hole in carry out the threaded of internal thread, the iron pin of the threaded middle generation of screw thread is drained in the cavity in support tube.
The present invention is modeled to the environment for use of spiral shell to be processed cover by connecting cylinder, before changing machining internal thread be beyond full diameter of thread be the custom thinking of benchmark, owing to the hole internal thread of processing spiral shell cover is by benchmark of the center axis of spiral shell cover, ensure that the concentricity of spiral shell cover internal and external threads, meet the processing request of the spiral shell cover of high precision concentricity requirement.
