Abstract
The present invention relates to a kind of bracing the bit device, including rotating base, drill bit, rotating base front end is extended with the adapter sleeve of corresponding drill bit, the some self-locking holes of adapter sleeve sidewall, is provided with some self-locking blocks in self-locking hole, and described self-locking block stretches into installing hole inner chamber；Side end face, self-locking block remotely mounted hole one is inclined plane, adapter sleeve outer wall is set with the fixed cover of corresponding self-locking block, arranges fixed cover, drives fixed cover to rotating base direction, utilize fixed cover inwall inclined plane to drive self-locking 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 bracing the bit 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 drill bit
Bracing means.
The concrete technical scheme of the present invention is: a kind of bracing the bit device, including rotating base, drill bit, before rotating base
End is extended with the adapter sleeve of corresponding drill bit, the some self-locking holes of adapter sleeve sidewall, is provided with some self-locking blocks, described self-locking in self-locking hole
Block stretches into installing hole inner chamber；Side end face, self-locking block remotely mounted hole one is inclined plane, and adapter sleeve outer wall is set with corresponding self-locking block
Fixed cover, described fixed cover inwall is provided with the inclined plane of corresponding self-locking block.
Described self-locking hole quantity is 4；Self-locking block is provided with zigzag end face near installing hole one side end face；Self-locking block tilts
Face is provided with screw thread, and fixed cover inwall is provided with the female thread of corresponding self-locking block.
Advantageous Effects: arrange fixed cover, drives fixed cover, utilizes fixed cover inwall inclined plane to rotating base direction
Drive self-locking block, thus it is fixing to drive the fast inward displacement of self-locking to realize drill bit；Simple in construction, good fixing effect；Sawtooth is set
Shape end face, contributes to strengthening the fastness of drill bit clamping；By Screw assembly fixed cover and self-locking block, annexation consolidates, makes
The two connects more stable, thus ensures drill bit quality of connection.
Accompanying drawing explanation
Accompanying drawing 1 is this apparatus structure sketch；
Accompanying drawing 2 installs sketch for drill bit.
Figure 1 is rotating base, 2 be adapter sleeve, 3 be fixed cover, 4 be self-locking block, 5 for drill bit.
Detailed description of the invention
A kind of bracing the bit device, sees Fig. 1-2: including rotating base 1, drill bit 5, it is right that rotating base 1 front end is extended with
Answering the adapter sleeve 2 of drill bit 5, the some self-locking holes of adapter sleeve 2 sidewall, be provided with some self-locking blocks 4 in self-locking hole, described self-locking block 4 is stretched
Enter installing hole inner chamber；Side end face, self-locking block 4 remotely mounted hole one is inclined plane, and adapter sleeve 2 outer wall is set with corresponding self-locking block 4
Fixed cover 3, described fixed cover 3 inwall is provided with the inclined plane of corresponding self-locking block 4.
Described self-locking hole quantity is 4；Self-locking block 4 is provided with zigzag end face near installing hole one side end face；Self-locking block 4 inclines
Inclined-plane is provided with screw thread, and fixed cover 3 inwall is provided with the female thread of corresponding self-locking block 4.
Fixed cover 3 is set, drives fixed cover 3 to rotating base 1 direction, utilize fixed cover 3 inwall inclined plane to drive self-locking
Block 4, 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,
Contribute to strengthening the fastness of drill bit 5 clamping；By Screw assembly fixed cover 3 and self-locking block 4, annexation consolidates, makes the two
Connect more stable, thus ensure drill bit 5 quality of connection.
