Abstract
The present invention relates to a kind of self-locking drill bit connecting device, including rotating base, drill bit, it is characterized in that: in the middle part of rotating base, be provided with the installing hole of corresponding drill bit, installing hole side is along some self-locking hole is distributed, some self-locking blocks it are provided with in described self-locking hole, self-locking block stretches into installing hole inner chamber, and side end face, self-locking block remotely mounted hole one is inclined plane, is provided with the inserted block of corresponding self-locking block in self-locking hole；Described inserted block is provided with outer end and stretches out rotating base end face, and the inner is provided with the inclined plane of corresponding self-locking block；Arranging ring flange, during drill bit uses, owing to drill bit is by axial compressive force, ring flange presses inserted block, thus it is fixing to drive the fast inward displacement of self-locking to realize drill bit；Simple in construction, good fixing effect；Zigzag end face is set, contributes to strengthening the fastness of drill bit clamping.
Description
Technical field
The present invention relates to field of machining, be specifically related to a kind of self-locking drill bit connecting device.
Background technology
In machining, utilizing drilling equipment to carry out boring is common processing mode, and existing drill bit typically passes through
Connect between snap fastener, but owing to some metal works hardness are relatively big, drill bit in use suffered torsion is relatively big, commonly
The mode that clamps connect built on the sand.
Summary of the invention
In order to solve the problems referred to above, it is provided that a kind of more firm drill bit type of attachment, the present invention devises a kind of self-locking
Formula drill bit connecting device.
The concrete technical scheme of the present invention is: a kind of self-locking drill bit connecting device, and including rotating base, drill bit, it is special
Levy and be: being provided with the installing hole of corresponding drill bit in the middle part of rotating base, installing hole side is along some self-locking hole being distributed, in described self-locking hole
Being provided with some self-locking blocks, self-locking block stretches into installing hole inner chamber, and side end face, self-locking block remotely mounted hole one is inclined plane, in self-locking hole
It is provided with the inserted block of corresponding self-locking block；Described inserted block is provided with outer end and stretches out rotating base end face, and the inner is provided with inclining of corresponding self-locking block
Inclined-plane；Drill tip outer is provided with the ring flange of corresponding inserted block.
Described self-locking hole quantity is 4；Self-locking block is provided with zigzag end face near installing hole one side end face；Hole depth is installed
Degree is more than the distance of ring flange distance bit face；Lubricating oil it is provided with in self-locking hole.
Advantageous Effects: arrange ring flange, during drill bit uses, owing to drill bit is by axial compressive force, ring flange
Press inserted block, thus it is fixing to drive the fast inward displacement of self-locking to realize drill bit；Simple in construction, good fixing effect；Zigzag is set
End face, contributes to strengthening the fastness of drill bit clamping.
Accompanying drawing explanation
Accompanying drawing 1 is this apparatus structure sketch；
Accompanying drawing 2 is mounting seat end view；
Accompanying drawing 3 installs sketch for drill bit.
Figure 1 is rotating base, 2 be installing hole, 3 be self-locking block, 4 be inserted block, 5 be drill bit, 6 for ring flange.
Detailed description of the invention
A kind of self-locking drill bit connecting device, sees Fig. 1-3: include rotating base 1, drill bit 5, it is characterized in that: rotate the end
Being provided with the installing hole 2 of corresponding drill bit 5 in the middle part of seat 1, installing hole 2 side is along some self-locking hole being distributed, if being provided with in described self-locking hole
Dry self-locking block 3, self-locking block 3 stretches into installing hole 2 inner chamber, and side end face, self-locking block 3 remotely mounted hole 2 one is inclined plane, in self-locking hole
It is provided with the inserted block 4 of corresponding self-locking block 3；Described inserted block 4 is provided with outer end and stretches out rotating base 1 end face, and the inner is provided with corresponding self-locking block 3
Inclined plane；Drill bit 5 end outer is provided with the ring flange 6 of corresponding inserted block 4.
Described self-locking hole quantity is 4；Self-locking block 3 is provided with zigzag end face near installing hole 2 one side end face；Installing hole 2
The degree of depth is more than the ring flange 6 distance apart from drill bit 5 end face；Lubricating oil it is provided with in self-locking hole.
Ring flange 6 is set, during drill bit 5 uses, owing to drill bit 5 is pressed inserted block 4 by axial compressive force, ring flange 6,
Thus it is fixing to drive the fast inward displacement of self-locking to realize drill bit 5；Simple in construction, good fixing effect；Zigzag end face is set, helps
In the fastness strengthening drill bit 5 clamping.
