Description
Technical field
The utility model belongs to mechanical production devices field, is specifically related to a kind of boring positioner.
Background technology
During boring, be unable to do without the positioner to processing work, thus ensure the reliable of borehole accuracy.Especially, in the production process of drilling tool, positioner seems particularly important.
As everyone knows, drilling tool is the indispensable construction tools such as the energy (power station, hydraulic engineering), traffic (railway, highway), mine, quarrying, urban construction (foundation ditch, road milling).The competition (quality, price) in drilling tool market is growing more intense, and only has quality is good, cost performance is worthwhile product just can obtain the accreditation in market.
Drilling tool primarily of drill steel, bore bit and bit shank three part composition, wherein one of the main machining operations of drill steel is exactly Centre Hole Burr, the only quality of the guaranteed accurate location guarantee drill steel to drill steel boring, and existing drilling-hole positioning device is simple and crude, use very inconvenient, and positioning precision is also poor, working (machining) efficiency and the quality of drill steel can not be ensured, therefore, be necessary to transform drilling-hole positioning device.
Summary of the invention
The purpose of this utility model is to provide the boring positioner that a kind of structure is simple, easy to operate, location machining accuracy is high.
Based on above-mentioned purpose, the utility model takes following technical scheme: a kind of boring positioner, comprise base and be positioned at the cover plate on base, described base top offers V-shaped groove, the middle part of described cover plate is inverted V-shaped, the region surrounded between described V-shaped groove and cover plate forms clamping part, and one end of described cover plate is connected with base rotation by bearing pin, and the other end is flexibly connected with base by the locking device be provided with in base.
Described locking device comprises clamping screw, and clamping screw comprises the bearing pin that screw rod is fixedly connected with screw rod one end, and the screw rod other end is provided with nut and pad, and clamping screw is connected with base rotation by bearing pin; Described cover plate is provided with the draw-in groove matched with described clamping screw.
Described clamping part is square.
Described base both sides inwardly offer groove, are provided with downward screw, are provided with set bolt in screw.
Compared with prior art, the beneficial effects of the utility model are: the utility model, by base and deck design forming V-shape structure, makes it the clamping part regular shape surrounded, especially square clamping part, are conducive to clamping stable; On the other hand, the square center surrounded and the center superposition of processing work, can realize the locating and machining of centre bore very soon, be particularly suitable for drilling tool boring to use, therefore, structure of the present utility model is simple, location machining accuracy is high, operate convenience, has boundless application prospect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of locking device in Fig. 1.
Detailed description of the invention
A kind of boring positioner, as depicted in figs. 1 and 2, base 1 and the cover plate 2 be positioned in inverted V-shaped on base, base 1 top offers V-shaped groove, and base 1 both sides inwardly offer groove 3, is provided with downward screw 4 in groove 3, set bolt 5 is provided with, for firm banking 1 in screw 4.
The region surrounded between V-shaped groove and cover plate 2 forms square clamping part 6, and one end of cover plate 2 is rotationally connected by bearing pin 7 and base 1, and the other end is flexibly connected with base 1 by locking device.
Locking device comprises clamping screw, and clamping screw comprises the bearing pin 12 that screw rod 8 is fixedly connected with screw rod 8 one end, and screw rod 8 other end is provided with nut 9 and pad 10, and clamping screw is rotationally connected by bearing pin 12 and base 1; Cover plate 2 is provided with the draw-in groove 11 matched with clamping screw.
When this novel middle positioner uses, first processing work is placed on the clamping part 6 of positioner, then screw rod 8 is turned in the draw-in groove 11 on cover plate 2, locked with nut, during dismounting, only need be opened clamping screw, therefore, the utility model installation and removal processing work is simple.In addition, adopt square clamping part 6, be specially adapted to the processing of rod aperture (as drill steel), be conducive to clamping stable; On the other hand, the square center surrounded and the center superposition of processing work, can realize the location of center machining hole very soon, and especially during drilling tool boring, location machining accuracy is high, operates also very convenient, have boundless application prospect.
