Abstract
The utility model relates to a kind of Novel drilling device, and this drilling equipment comprises: drillstock cover, locating pin one, large drill, aperture drill bit, adjusting bolt, locating pin two; Described drillstock cover is cylindrical structural, and its center is provided with an internal taper hole, and an adjusting bolt is established at top, and adjusting bolt can move up and down as required; Opposite end at described drillstock cover is provided with locating pin one, locating pin two; The tapered structure of large drillstock profile of large drill, matches with the internal taper hole of drillstock cover; The center of whole large drill is provided with a through hole, and aperture drill bit can run through whole through hole, and the end of its little drillstock contacts with adjusting bolt; Opposite end at described large drill is longitudinally provided with mounting hole.The utility model drilling equipment is not only simple in structure, easy to operate, and the length that can adjust as required little drill bit processes, and has not only ensured axiality but also reduced production cost.
Description
Technical field
The utility model belongs to mechanical manufacturing field, particularly a kind of Novel drilling device.
Background technology
At machinery industry, processing step hole is very general operation, and traditional method is the processing in Yi Ge hole, a hole, but this method exists certain drawback.If in the case of the axiality of stepped hole is had relatively high expectations, this method is just difficult to meet technical requirement, thereby cause a large amount of wastes.
Utility model content
For overcoming above-mentioned defect, the technical problems to be solved in the utility model be to provide a kind of simple in structure, easy to operate and can ensure axiality require drilling equipment.
A kind of Novel drilling device, this drilling equipment comprises: drillstock cover, locating pin one, large drill, aperture drill bit, adjusting bolt, locating pin two; Described drillstock cover is cylindrical structural, and its center is provided with an internal taper hole, and an adjusting bolt is established at top, and adjusting bolt can move up and down as required; Opposite end at described drillstock cover is provided with locating pin one, locating pin two; The tapered structure of large drillstock profile of large drill, matches with the internal taper hole of drillstock cover; The center of whole large drill is provided with a through hole, and aperture drill bit can run through whole through hole, and the end of its little drillstock contacts with adjusting bolt; Opposite end at described large drill is longitudinally provided with mounting hole.
The utility model drilling equipment is not only simple in structure, easy to operate, and the length that can adjust as required little drill bit processes, and has not only ensured axiality but also reduced production cost.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model drilling equipment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, a kind of Novel drilling device, this drilling equipment comprises: drillstock cover 1, locating pin 1, large drill 3, aperture drill bit 4, adjusting bolt 5, locating pin 26.Drillstock cover 1 is cylindrical structural, and its center is provided with an internal taper hole, and an adjusting bolt 5 is established at top, and adjusting bolt 5 can move up and down as required; Opposite end at drillstock cover 1 is provided with locating pin 1, locating pin 26.The tapered structure of large drillstock 8 profile of large drill 3, matches with the internal taper hole of drillstock cover 1; The center of whole large drill 3 is provided with a through hole 10, and aperture drill bit 4 can run through whole through hole, and the end of its bradawl handle 9 contacts with adjusting bolt 5.Opposite end at large drill 3 is longitudinally provided with mounting hole 7.
In the time that needs are holed, the internal taper hole that first large drill 2 is packed into drillstock cover 1 forms tight fit (mounting hole 7 of noting opposite end on large drill 3 will match with the locating pin 1, the locating pin 26 that are positioned on drillstock cover 1), again aperture drill bit 4 is packed in the through hole 10 of large drill 3, regulate adjusting bolt 5 to locate according to aperture Len req, after length is fixing, screwed in place nail 1, locating pin 26 are locked aperture drill bit 4.Finally whole drilling equipment is connected and is holed with machine tool chief axis.
The utility model improves on the basis of existing concentric step drill bit, because step drill bit can not regulate the length of drill bit as required, and the utility model can regulate size and the length of aperture drill bit as required, both ensured the axiality requirement of product, reduce again production cost.
