Specific implementation mode
Embodiment 1：
In Fig. 1, a kind of lathe drill bit fixing device, including grip block 1, locating piece 2 and precession bar 3, the grip block 1
Equipped with through-hole 101, locating piece 2 is placed in through-hole 101, and precession bar 3 is threadedly coupled with grip block 1, and 3 one end of precession bar is resisted against
On locating piece 2.Thus structure is it is found that locating piece 2 is placed in through-hole 101, and when precession 3 precession of bar pushes locating piece 2 to advance, and bores
Head, which is put into front end, can step up to fix, and then by 1 clamping of grip block on tool apron, can carry out bore operation.Work as completion of processing
Afterwards, grip block 1 is removed, precession bar 3 is exited, drill bit can be removed.Since precession bar 3 is threadedly coupled with grip block 1, when rotation is revolved
Into that can realize moving forward and backward for precession bar 3 when bar 3, locating piece 2 can be pushed to clamp drill bit in this way, and be not easy to loosen, when
When needing to dismantle drill bit, need to only rotate the retrogressing of precession bar 3 can unclamp locating piece 2, then remove drill bit.The time saving province of whole process
Power, it is easy to use.
Preferably scheme, 101 one end of through-hole have the first circular arc cutaway, 2 one end of locating piece have with it is first arc-shaped
Corresponding second circular arc cutaway of notch.Thus it is found that when precession bar 3 pushes locating piece 2 to compress drill bit, first justifies structure
Arc notch wraps up drill bit with the second circular arc cutaway, and contact area is big, increases frictional force.
Preferably scheme, as shown in Fig. 2, precession bar 3 includes screw rod 301,301 one end of screw rod is fixedly connected with handle 302.
Thus it is found that screw rod 301 is connected through a screw thread with grip block 1, handle 302 is conveniently operated personnel and rotates precession bar 3, precession structure
Bar 3 there has been precessing force using screw-thread fit, with this come push locating piece 2 advance.
Preferably scheme, as shown in figure 3, locating piece 2 includes pedestal 201 and the jacking block 202 for being fixed on 201 one end of pedestal,
202 material of jacking block is manganese alloy.Thus for structure it is found that 3 one end of precession bar is resisted against 202 one end of jacking block, jacking block 202 compresses drill bit
Reach fixed purpose.Manganese alloy material has good wear-resisting effect.
Preferably scheme, as shown in figure 3,201 one end of pedestal is equipped with blind hole 203, blind hole 203 is inserted into one end of precession bar 3
It is interior.Thus structure in precession and during step up drill bit, can preferably ensure it is found that precession bar 3 is inserted into blind hole 203
The play of locating piece 2.
Preferably scheme, as shown in figure 3,202 one end of jacking block has skid resistant course 204.Skid resistant course 204 is zigzag, is improved
The roughness of contact surface, and then increasing friction force achieve the effect that better fixed drill bit.
Preferably scheme, locating piece 2 are equipped with plane bearing, and 3 one end of precession bar is resisted against the plane bearing of locating piece 2
On.Thus it is found that while precession bar 3 is during pushing locating piece 2 to move, 3 relative positioning block 2 of precession bar is revolving structure
Turn, plane bearing, which is not shown in figure, to be arranged on locating piece 2, is caused when can reduce the rotation of 3 relative positioning block 2 of precession bar in this way
Friction, while not influencing propulsive force.
As shown in figure 4, Fig. 4 is the fixing device and drill bit assembling schematic diagram of the utility model.Locating piece 2 and grip block 1
Cooperation, precession bar 3 push the clamping drill bit 4 of locating piece 2 to achieve the purpose that fixed drill bit.
A kind of drill bit fixing device provided by the utility model, including grip block, locating piece and precession bar, grip block are equipped with
Through-hole, locating piece are placed in through-hole, and precession bar is threadedly coupled with grip block, and precession bar one end is resisted against on locating piece, is passed through
Precession bar applies pressure and locating piece is pushed to clamp drill bit, and grip block clamping is then adjusted lathe in machining on knife rest
The automatic drilling of parameter, that is, practicable workpiece, improves production efficiency and product quality, reduces the operation intensity of worker, works as brill
After the completion of hole, precession bar i.e. demountable bit is exited, operation is simple and reliable, economical and practical.
