It is required for whether on the same line redefining hole and drill bit after upset, result in process repetition, the frock time is elongated, production
Efficiency step-down and obtained hole precision is not also high.
Utility model content
The technical problems to be solved in the utility model:There is provided it is a kind of can quickly position and registration lock core drillman
Dress, to overcome the deficiencies in the prior art.
The technical solution of the utility model：A kind of lock core drilling tool, including clamp body, the lock core with tapered end are described
Clamp body is provided with positioning sleeve and positioning seat, and lock core insertion positioning sleeve, the positioning seat includes rotational positioning portion, curved support
Portion, the rotational positioning portion is provided with vallecular cavity, and vallecular cavity is provided with keeper and spring, and the extended vallecular cavity of keeper simultaneously inserts lock core
Machined hole.
The keeper end is cambered surface.
The keeper include bearing pin, bearing pin include spring stack portion, bearing pin sliding block, the spring housing in spring stack portion,
The bearing pin sliding block is slided along vallecular cavity, and the end of the bearing pin sliding block sets steel ball structure.
Stroke limit groove is set on the bearing pin sliding block, and the vallecular cavity wall in rotational positioning portion opens up spacing hole, and limited block is worn
Cross the spacing hole, in insertion stroke limit groove so that bearing pin sliding block is slided in the range of stroke limit.
The clamp body is fastenedly connected with positioning seat by screw.
Opened up on the barrel of the positioning sleeve in screwed hole, screwed hole and be fitted with threaded fastener.
The beneficial effects of the utility model：
The utility model can be when carrying out workpiece lock core drilling tool, it is only necessary to which lock core is put into positioning seat and positioning
Set, is fixed and rotates, you can be accurately positioned the position in hole to be processed as requested, saves the frock time and positions more
Accurately.
