Abstract
The utility model discloses the harness of a kind of drilling center-punching, bore lid (1), top board (2) by joining, lower platen (3), screw rod (4), wing nut (5), sample flushing device (6) form, screw rod (4) lower end is welded on the centre position of lower platen (3), to be screwed on wing nut (5) by the through hole of top board (2) in upper end, join and bore lid (1) and be located between top board (2) and lower platen (3), it is characterized in that establishing sample flushing device (6) and drilling (7) joining to bore to cover on (1).This drilling center-punching harness, compared with the method for current center-punching, has structure simple, easy to operate, time saving and energy saving, can ensure the center in hole, the advantage of improving the quality of products.
Description
Technical field
The utility model relates to a kind of utensil of center-punching, specifically a kind of drilling center-punching harness.
Background technology
At present, some factory, when drilling and tapping, be generally first will join drill body and join brill to cover stacked, press to join and bore lid, with scriber by joining the drilling boring and cover, the circumference in hole is drawn, then according to circumference alignment, after center is found out, charge and attack central eye with sample, then hole, the operation of above-mentioned center-punching, generally apply though existing, but also there is weak point: one is that operation is cumbersome, and operation is many, wastes time and energy; Two be draw hole and knock sample rush time, join and bore lid and join drill body and be easily shifted, the hole drawing and get out, be difficult to ensure the distance between the center in hole and Kong Yukong, affect product quality.
Summary of the invention
It is simple, easy to operate, time saving and energy saving that the purpose of this utility model is to provide a kind of structure, can ensure the center in hole, the drilling center-punching harness of improving the quality of products.
For reaching above object, technical solution adopted in the utility model is: this drilling center-punching harness, bore lid by joining, top board, lower platen, screw rod, wing nut, sample flushing device form, screw rod lower end is welded on the centre position of lower platen, to be screwed on wing nut by the through hole of top board in upper end, join and bore lid and be located between top board and lower platen, it is characterized in that covering and establishing sample flushing device and drilling joining brill.The utility model is also implemented by following measure: described sample flushing device, and by stable cover, sample jumper bar, rush to summit, rush point and form, sample jumper bar upper end establishes lower end of rushing to summit to establish punching point, its external diameter and drilling and to stablize the internal diameter overlapped consistent.When using the utility model, first wing nut is backed out, take off top board and join and bore lid, be placed in above lower platen by joining drill body, then joining and bore lid and be placed in and join on drill body, with top board and wing nut, reinforcing joining to bore to cover and join drill body, then with vice, lower platen is clipped, prevent from moving when knocking sample and rushing; When center-punching, first sample jumper bar is inserted in the drilling of joining and boring and covering, then stable cover is enclosed within sample jumper bar, press and stablize cover and pound with a hammer and rush to summit, punching point is got sample dotting punch, after getting first sample dotting punch, by above-mentioned operation, continuously the sample dotting punch of joining drill body is beaten, then holed.
The beneficial effects of the utility model are: compared with the method for current center-punching, have structure simple, easy to operate, time saving and energy saving, can ensure the center in hole, the advantage of improving the quality of products.
Accompanying drawing explanation
Fig. 1 is the utility model structure schematic front view.
Fig. 2 is that the utility model sample flushing device 6 structure master is depending on analysing and observe enlarged diagram.
Detailed description of the invention
The utility model is made with reference to accompanying drawing 1,2.This drilling center-punching harness, bore lid 1 by joining, top board 2, lower platen 3, screw rod 4, wing nut 5, sample flushing device 6 form, screw rod 4 lower end is welded on the centre position of lower platen 3, to be screwed on wing nut 5 by the through hole of top board 2 in upper end, join and bore lid 1 and be located between top board 2 and lower platen 3, it is characterized in that establishing sample flushing device 6 and drilling 7 joining to bore on lid 1.Described sample flushing device 6, by stable cover 6a, sample jumper bar 6b, the 6c that rushes to summit, rush sharp 6d and form, sample jumper bar 6b establishes upper end 6c lower end of rushing to summit to establish and rushes sharp 6d, its external diameter and drilling 7 and the stable internal diameter overlapping 6a consistent.
