A kind of drilling aid, including drill bushing, bearing, fixing seat；The drill bushing is arranged in bearing, the fixed seating
Set on bearing；The drill bushing, bearing are successively cooperatively connected between fixing seat.
In the drilling aid, the drill bushing is provided with the chamfering for drill bit guiding on inner wall surface thereof top.
It is radially outwardly extending at the top of the outer ring of the drill bushing to be equipped with molding card in conjunction in the drilling aid
Ring, the snap ring are connected to bearing.
In the drilling aid, the bearing is deep groove ball bearing or tapered roller bearing or aligning roller axis
It holds.
In the drilling aid, the drill bushing is carbon tool steel drill bushing or alloy tool steel drill bushing.
In the drilling aid, the fixing seat is equipped with molding ring block in conjunction in its intracavity bottom,
The bearing is connected to ring block.
In the drilling aid, the fixing seat is provided with pin hole used for positioning and for bolted logical
Hole.
In the drilling aid, the pin hole, through-hole quantity be 2, and diagonal be arranged in the fixation
The quadrangle of seat.
The utility model has the advantages that
The utility model provides a kind of drilling aid, and the drill bushing is installed on by the bearing of matched connection
Fixing seat achievees the purpose that removable, replacement, and in bit work, can effectively slow down and cause because of drill bit shake
Drill bushing abrasion.The chamfering being provided at the top of the drill bushing, plays guiding role to drill bit, drill bit is enabled smoothly to be inserted into drill bushing.
Using carbon tool steel drill bushing or alloy tool steel drill bushing, the intensity of drill bushing is improved, effectively reduces abrasion.Two positioning are set
Pin hole can promote drilling aid to be mounted on drilling tool with high positioning accuracy, then by two through hole into
The connection of row bolt fastening, drilling aid is secured firmly on drilling tool.The utility model installs brill by bearing
Set, is slowed down drill bit using the buffer function of bearing to impact force brought by drill bushing, drill bushing is avoided to wear, and be able to achieve brill
The disassembling, assembling and replacing of set, bearing, can use different drill bushings, bearing instead, expand drilling aid when coping with different operating conditions
Range of applicability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of drilling aid provided by the utility model.
Fig. 2 is the cross-sectional view of drilling aid provided by the utility model.
Specific embodiment
The utility model provides a kind of drilling aid, to make the purpose of this utility model, technical solution and effect more
Add clear, clear, the utility model is further described as follows in conjunction with drawings and embodiments.It should be appreciated that this place
The specific embodiment of description only to explain the utility model, is not used to limit the utility model.
Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of drilling aid.Including drill bushing 1, bearing 2, fixing seat
3；Drill bushing 1 is arranged in bearing 2, and fixing seat 3 is sheathed on bearing 2；Drill bushing 1, bearing 2 are successively cooperatively connected between fixing seat 3.?
In boring procedure, bit shake can generate radial impact and tangential impact to drill bushing 1 when drill bit collides drill bushing 1.Its
In, radial impact can be buffered by bearing 2, weaken；Since drill bushing 1 is mounted on bearing 2, it is suitable that tangential impact will lead to drill bushing 1
Drill bit direction of rotation rotation, significantly reduce the relative motion and friction between drill bit and drill bushing 1, the energy of tangential impact
Amount is converted into the rotation function of drill bushing 1 Yu bearing 2, wears so as to avoid the fever of 1 inner wall of drill bushing.
Further, drill bushing 1 is provided with the chamfering 4 for drill bit guiding on inner wall surface thereof top.In bit work,
By the guiding role of chamfering 4, drill bit can be smoothly inserted into drill bushing 1.
Further, radially outwardly extending at the top of the outer ring of drill bushing 1 to be equipped with molding snap ring 5 in conjunction, snap ring 5 is connected to axis
Hold 2.Drill bushing 1 and the interference fit of bearing 2 connect, what the setting of snap ring 5 can avoid imposing in drill bit insertion process drill bushing 1 by drill bit
Active force and move down.
Further, when bore diameter is less than or equal to 8mm, deep groove ball bearing is selected to use；When bore diameter is greater than 8mm
When use tapered roller bearing；When drill bit, which has naked eyes, to understand the shake perceived, self-aligning roller bearing is selected.
Further, drill bushing 1 is carbon tool steel drill bushing.Moreover, drill bushing 1 is handled by nitriding and hardened face, it can
The hardness for effectively improving 1 inner wall of drill bushing effectively reduces the abrasion of drill bushing 1.In another specific embodiment, alloy tool is selected
Steel drill bushing.
Further, fixing seat 3 is equipped with molding ring block 6 in conjunction in its intracavity bottom, and bearing 2 is connected to annular
Block 6.Bearing 2 and the interference fit of fixing seat 3 are understood, and by the way that ring block 6 is arranged, bearing 2 are supported, prevents bearing 2 because of drill bit
It is violent rotation and move down.
Further, fixing seat 3 is provided with pin hole 7 used for positioning and for bolted through-hole 8.
As shown in Figure 1, further, pin hole 7, through-hole 8 quantity be 2, and be diagonally arranged in the four of fixing seat 3
Angle.
Further, the inner wall of drill bushing 1 has done the processing of carburizing, nitriding and quenching, to improve the hard of 1 inner wall of drill bushing
Degree, enhances its wear-resisting property, effectively reduces the abrasion of drill bushing 1.
In another specific embodiment, drilling aid is directly fixed on drilling tool by welding
On.
In conclusion the utility model provides a kind of drilling aid, the bearing that drill bushing passes through matched connection
It is installed on fixing seat, achievees the purpose that removable, replacement, and in bit work, can effectively be slowed down because drill bit is shaken
The abrasion of drill bushing caused by and.The chamfering being provided at the top of drill bushing, plays guiding role to drill bit, drill bit is enabled smoothly to be inserted into brill
Set.Using carbon tool steel drill bushing or alloy tool steel drill bushing, the intensity of drill bushing is improved, effectively reduces abrasion.Setting two
The pin hole of positioning can promote drilling aid to be mounted on drilling tool with high positioning accuracy, then logical by two
Hole carries out bolt fastening connection, and drilling aid is secured firmly on drilling tool.The utility model is pacified by bearing
Drill bushing is filled, slows down drill bit using the buffer function of bearing to impact force brought by drill bushing, drill bushing is avoided to wear, and can be real
The disassembling, assembling and replacing of existing drill bushing, bearing, can use different drill bushings, bearing instead when coping with different operating conditions, expand drilling auxiliary dress
