Description
Technical field
It the utility model is related to field of drill, more particularly to a kind of regeneration hard alloy straight fluted drill.
Background technology
Drill bit be on solid material drilling go out through hole or blind hole, and can be to the cutter of existing hole reaming.It is common
Drill bit mainly have fluted drill, chit drill, centre drill, depth drill and cylindrical drill.Though reamer and counterbit cannot be on solid materials
Drilling, but they are also traditionally included into drill bit one kind.
Industrially there are a variety of methods to regenerate hard alloy, chemical method and physical method are broadly divided into, by hard
Alloy regeneration, so as to save resource, reduces manufacture cost, and the generally pylindrical structure of existing drill bit, is being bored
For the size inconvenience control of drilling when hole, different drill bits is needed replacing when different size of hole is processed,
The time of user's processing is just wasted when more bit change, brings inconvenience for user, and replace different drill bits
Also increase use cost.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, there is provided one kind regeneration hard alloy straight-flute drill
Head.
The utility model is to be achieved through the following technical solutions：
One kind regeneration hard alloy straight fluted drill, including connecting shaft, the connecting shaft upside is welded with fixed link, described solid
Fixed pole upper end is welded with drill bit, and the fixed link surrounding is welded with casing, and described sleeve pipe internal welding is connected to cage plate, in the cage plate
Side is welded with helical spring, described spiral
Spring inner is socketed with guide rod, and described guide rod the inner is installed with baffle, and the guide rod outer end is installed with
Polishing plate.
As the optimal technical scheme of the utility model, the polishing plate section is triangular structure and is that regeneration hard closes
Golden material is formed.
As the optimal technical scheme of the utility model, the guide rod coordinates with cage plate sliding.
As the optimal technical scheme of the utility model, the drill bit is made of cemented carbide material.
As the optimal technical scheme of the utility model, described sleeve pipe right-angled intersection forms straight trough.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is by setting helical spring and polishing plate, by the cooperation of the two, consequently facilitating to the straight of drilling
Footpath is controlled, consequently facilitating drilling out different size of hole, is avoided and is replaced different drill bits back and forth, has saved user's drilling
Time, the convenient hole that different-diameter is drilled out in the case where drilling machine does not take out, the present apparatus, can be with by the pulling of helical spring
Polishing plate is gradually moved out, with the increase in hole, make polishing plate contact hole all the time, so as to process different-diameter
Hole, and it is easy to operate, design is reasonable, is worth being promoted the use of.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the top view of the utility model.
In figure：1st, drill bit, 2, polishing plate, 3, connecting shaft, 4, guide rod, 5, cage plate, 6, helical spring, 7, baffle, 8, casing,
9th, fixed link.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, in the utility model embodiment
Technical solution be clearly and completely described, it is clear that described embodiment is only the utility model one
Divide embodiment, instead of all the embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not having
All other embodiments obtained under the premise of creative work are made, shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：
One kind regeneration hard alloy straight fluted drill, including connecting shaft 3, the upside of connecting shaft 3 are welded with fixed link 9, institute
State 9 upper end of fixed link and be welded with drill bit 1, the drill bit 1 is made of cemented carbide material, and 9 surrounding of fixed link is welded with set
Pipe 8,8 right-angled intersection of described sleeve pipe form straight trough, and 8 internal welding of described sleeve pipe is connected to cage plate 5, and the inner side of cage plate 5 is welded with spiral shell
Spring 6 is revolved, guide rod 4 is socketed with inside the helical spring 6, the guide rod 4 coordinates with the sliding of cage plate 5, and the guide rod 4 is inner solid
Dingan County is equipped with baffle 7, and 4 outer end of guide rod is installed with polishing plate 2, and 2 section of the polishing plate is triangular structure and is
Cemented carbide material is regenerated to form.
Operation principle：Connecting shaft 3 is installed on electric drill shaft junction first, drill bit 1 is placed on the upper surface of workpiece, so
It is followed by being powered and bores, makes electric drill drive connecting shaft 3 to rotate, so as to drive drill bit 1 to rotate, by the rotation of drill bit 1, polishing can be made
Plate 2 rotates, and polishing plate 2 is entered in the hole of processing, due to the presence of helical spring 6, it will and air exercise nog plate 2 promotes inwards, with
The increase in hole, so that polishing plate 2 is gradually to external expansion, so as to process the hole of different-diameter, when drilling
More bit change 1 back and forth is avoided, so as to save time of the user to Workpiece boring.
While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art,
It is appreciated that in the case where not departing from the principle of the utility model and spirit
A variety of change, modification, replacement and modification can be carried out to these embodiments, the scope of the utility model is by appended power
Profit requires and its equivalent limits.
