The present invention has positive effect: thread chasing bar of the present invention is a kind of device that carries out tapping by means of the positioning component double thread, this device carries out the occasion of thread tapping applicable to a plurality of thread Pilot holes of tapping for the treatment of to the same surface of a part, device designs and produces conveniently, cost is low, screw processing quality had both been guaranteed in practicality simple to operate, improved tapping efficient again, and screw tap is frangibility not, and effect is better.
Description of drawings
Fig. 1 is a thread chasing bar structural representation of the present invention;
Fig. 2 is the A-A cutaway view among Fig. 1;
Fig. 3 is the B-B cutaway view among Fig. 1.
The specific embodiment
See Fig. 1 to Fig. 3, thread chasing bar of the present invention has positioning component and screw tap 4.Positioning component has locating template 1, Template Location pin 2 and screw tap positioning sleeve 3.
According to the locating template 1 of a planar shaped plate body of tapping place configuration design on the part, on the plate body of locating template 1, be provided with seven cylindrical locating holes 11 according to processed screw thread quantity and processed screw position.
Screw tap positioning sleeve 3 is the steel integral piece of being made up of tapping-head section 31 and screw tap bar section 32, and the interior hole dimension of the tapping-head section 31 of screw tap positioning sleeve 3 is greater than the interior hole dimension of the screw tap bar section 32 of screw tap positioning sleeve 3.The external surface shape of screw tap bar section 32 is columniform external surface shape.The circumferential size of the peripheral dimension of the tapping-head section 31 of screw tap positioning sleeve 3 and the locating hole 11 of template 1 matches, and the diameter of the internal diameter of the tapping-head section 31 of screw tap positioning sleeve 3 and the tapping-head 41 of screw tap 4 matches.
During use, the linkage section 21 of two Template Location pins 2 inserts in the locating hole 11 of 1 two of locating templates, the positioning section 22 of Template Location pin 2 inserts to be treated in the thread Pilot hole of tapping part, the part of the whole or termination of the tapping-head section 31 of screw tap positioning sleeve 3 is inserted in the locating hole 11 of template 1, the tapping-head 41 of screw tap 4 is positioned among the tapping-head section 31 of screw tap positioning sleeve 3, and can rotate and slide along the axis direction of tapping-head section 31 with respect to tapping-head section 31, a part of bar section that the screw tap bar 42 of screw tap 4 is connected with tapping-head 41 be arranged in the screw tap bar section 32 of screw tap positioning sleeve 3.Diligent silk chuck or lengthening connect handle clockwise rotates screw tap 4, and adds to the active force of the direction of the thread Pilot hole of part and carry out thread tapping.Tapping process plug tap 4 is in positioning states all the time, thereby guarantees the precision of processed screw thread.After 5 hole processing are finished, Template Location pin 2 is taken out from two locating holes 11 in two locating holes 11 that insert tapping again, two locating holes 11 to not tapping carry out tapping again, all finish tapping up to all locating holes 11.
When the screw thread quantity of needs processing was 3, part had 3 thread Pilot holes, and locating template should have 3 locating holes mutually.During beginning, use 2 thread Pilot holes wherein to be used for the location earlier, 1 is used for tapping.After tapping was finished, this screwed hole of attacking silk can be used for the location, and carries out tapping to one in two other thread Pilot hole, up to all thread Pilot holes have all been carried out tapping.
