Description
Technical field
The present invention relates to a kind of frock fixed for crankshaft drilling.
Background technology
Bent axle is most important component in engine.It bears the power that connecting rod transmits, and is transformed into torque and passes through song
Axis exports and drives other annexes on engine to work.Bent axle is subject to the gas inertia of the centrifugal force of gyrating mass, mechanical periodicity
The collective effect of power and reciprocal inertia force, makes bent axle bear the effect of flexion torsion load.Therefore it is required that bent axle have it is enough strong
Degree and rigidity, journal surface need are wear-resisting, work is uniform, balance is good.
Bent axle on bent axle in process of production, it is necessary to carry out drilling operation, it is therefore desirable to use frock clamp to song
Axis is fixed, to realize drilling.Structure in the prior art for the frock clamp of fixed crankshaft is complex, the spirit used
Activity is relatively low, therefore causes the drilling efficiency of bent axle relatively low, therefore there is improved space.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of frock fixed for crankshaft drilling.
To achieve the above object, the present invention provides following technical solution：
A kind of frock fixed for crankshaft drilling, including bent axle positioning seat, gripping block and positioning plate；On the bent axle positioning seat
With the locating slot extended up and down, the upper end of the locating slot has limiting slot one, and limited block is arranged with the limiting slot one,
There is limiting slot two on the limited block；The positioning plate is installed on the top of bent axle positioning seat, and has on positioning plate pair
Quasi- hole, the alignment hole are corresponding with locating slot；The bent axle positioning seat, which corresponds to, has pilot pin, the folder on the side wall of locating slot
Tight block is connected on pilot pin, and gripping block can be rotated relative to pilot pin, and gripping block can turn to locating slot
On notch.
Preferably, the alignment hole screw-internal thread fit has locating sleeve.
Preferably, it is connected with handle in the gripping block.
Preferably, the gripping block has inclined plane towards the side of locating slot.
Preferably, the positioning plate includes fixed plate and movable plate, has link slot, the movable plate in the fixed plate
On be connected with contiguous block, the contiguous block is matched with link slot, and contiguous block can be moved along the depth direction of link slot, institute
Alignment hole is stated to be opened on movable plate.
Preferably, there is location hole, the location hole is connected with link slot, and location hole internal thread is matched somebody with somebody in the fixed plate
Conjunction has fixing bolt.
Advantages of the present invention is：When being operated to crankshaft drilling, the front end of bent axle is matched with locating slot, and utilizes clamping
Block clamps, and the crank arm of bent axle is matched with limiting slot two, carries out circumferential spacing fixation, after the completion of fixed, drill bit through pair
Quasi- hole is realized to crankshaft drilling, therefore structure of the present invention is relatively simple, and the drilling operation of personnel easy to operation, effectively raises
The efficiency of drilling；The setting of alignment hole at the same time, effectively avoids drilling and bores inclined situation, ensure that the quality of drilling；Due to
Limited block is fastened in limiting slot one, therefore can be changed limited block, can be replaced according to the actual size of bent axle
Change, there is the limited block of the limiting slot two closed with the matching size of crank arm in replacement so that the present invention use it is flexible
Property is obviously improved.
Brief description of the drawings
The schematic diagram for being used for the frock that crankshaft drilling is fixed that Fig. 1 is provided by the present embodiment；
The top view for being used for the frock that crankshaft drilling is fixed that Fig. 2 is provided by the present embodiment.
Embodiment
It is used to the frock that crankshaft drilling is fixed to the present invention by Fig. 1 to Fig. 2 be further described.
A kind of frock fixed for crankshaft drilling, including bent axle positioning seat 1, gripping block 2 and positioning plate 7；The bent axle
There is the locating slot 6 extended up and down, the section of the locating slot 6 is triangle, and the upper end of the locating slot 6 has on positioning seat 1
Limiting slot 1, is arranged with limited block 5 in the limiting slot 1, has limiting slot 2 51, the limiting slot two on the limited block 5
51 can supply the crank arm of bent axle to engage, and the situation for preventing bent axle from rotating in boring procedure with drill bit, improves drilling
Stability；The positioning plate 7 is installed on the top of bent axle positioning seat, and has alignment hole 9, the alignment hole 9 on positioning plate 7
Corresponding with locating slot 6, that is, when drilling, drill bit initially passes through alignment hole 9 and is contacted again with bent axle, realizes drilling, improves the essence of drilling
Exactness, reduces drilling and bores inclined situation；The bent axle positioning seat 1, which is corresponded on the side wall of locating slot 6, has threaded connection hole, spiral shell
Pilot pin 3 is combined with line connecting hole, the gripping block 2 is connected on pilot pin 3, and gripping block 2 can be relative to positioning
Bolt 3 rotates, and gripping block 2 can be turned on the notch of locating slot 6, and when needing to clamp various sizes of bent axle, it is fixed to rotate
Position bolt 3, can be adjusted the elastic of gripping block 2, to adapt to the clamping to various sizes of bent axle, improving the present embodiment makes
Flexibility, improves the efficiency of drilling.
Further, 9 screw-internal thread fit of alignment hole has locating sleeve 8, i.e., has internal thread in alignment hole 9, positions
