Abstract
Disclosed is a wheel drilling tool. The wheel drilling tool mainly solves problems that a product machined by an existing wheel drilling tool is assembled difficultly and the machining efficiency of the existing wheel drilling tool is low. The wheel drilling tool comprises an upper worktable, a lower worktable and a drill bit, and is characterized in that an arc chamber is arranged at a position, which is close to the bottom surface, of the drill bit, and the bottom surface of the drill bit is a circular conical surface. After a hole is drilled on a wheel by the drill bit, a chamfer is formed in the hole of the wheel, and accordingly the wheel can be conveniently assembled; and the wheel drilling tool is provided with a plurality of drill bits, so that the machining efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of boring bar tool, is specifically related to a kind of Wheel drilling instrument.
Background technology
With drill bit on solid material machining hole boring.The processing of the hole of various parts, remove a part by car, boring, mill etc. outside lathe completes, by pincers worker, utilize drilling machine and boring bar tool (drill bit, reamer, reamer etc.) to complete greatly.While holing on drilling machine, generally, drill bit should complete two motions simultaneously; Main motion, drill bit is around rotatablely move (cutting movement) of axis; Synkinesia, drill bit faces toward the rectilinear motion (feed motion) of workpiece along axis direction, during boring, mainly due to the shortcoming existed on drill bit structure, affect crudy, machining accuracy is generally below the IT10 level, and surface roughness is Ra12.5 μ m left and right, genus roughing.
Usually the boring bar tool of wheel is holed to wheel surface by drill bit, but does not establish a circular arc chamfering on the drill bit of existing Wheel drilling instrument, and the wheel circular hole processed does not so also have chamfering, inconvenience when causing the wheel assembling.And, there is now the Wheel drilling instrument all to only have a drill bit, greatly reduce like this operating efficiency.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of Wheel drilling instrument, has mainly solved existing Wheel drilling tool processes Product Assembly out and has been difficult for and the not high problem of working (machining) efficiency.
The technical scheme that the utility model adopts is: a kind of Wheel drilling instrument, comprise upper table, lower table and drill bit, and described drill bit is circular arc chamfering near the place, bottom surface, and the bottom surface of drill bit is taper seat.
Described upper table has a plurality of drill bits.
The beneficial effects of the utility model are: owing to taking technique scheme, after drill bit is holed to wheel, chamfering has just been arranged in the wheel hole, in wheel assembling time, just more like this; And be provided with a plurality of drill bits, greatly improved working (machining) efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure 1, upper table; 2, lower table; 3, drill bit; 4, bottom surface; 5, circular arc chamfering.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, a kind of Wheel drilling instrument, comprise upper table 1, lower table 2 and drill bit 3, and described drill bit 3 is circular arc chamfering 5 near 4 places, bottom surface, and the bottom surface 4 of drill bit 3 is taper seat.Like this, when the wheel that is positioned at lower table 2 when 3 pairs, drill bit is holed, place's circular arc chamfering can be processed, later wheel assembling will be greatly facilitated.
Described upper table 1 has a plurality of drill bits 3, and a plurality of drill bit 3 is all by a driven by motor, can play so the same with under effect, make the boring action of each drill bit 3 all consistent, greatly strengthened operating efficiency.
The utility model is not limited to above embodiment.
Claims (2)
1. a Wheel drilling instrument, comprise upper table (1), lower table (2) and drill bit (3), it is characterized in that: described drill bit (3) is located as circular arc chamfering (5) near bottom surface (4), and the bottom surface (4) of drill bit (3) is taper seat.
2. Wheel drilling instrument according to claim 1, it is characterized in that: described upper table (1) has a plurality of drill bits (3).
