Description
Technical field
The utility model is related to a kind of bent axle positioning tools.
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 other attachmentes on engine is driven to work.Bent axle is by the centrifugal force of gyrating mass, the gas inertia of 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 in process of production, needs to carry out drilling operation on bent axle, it is therefore desirable to use frock clamp to song
Axis is fixed, to realize drilling.The structure for being used for the frock clamp of fixed crankshaft in the prior art is complex, the spirit used
Activity is relatively low, therefore causes the drilling efficiency of bent axle relatively low, therefore there is improved spaces.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of bent axle positioning tool.
To achieve the above object, the utility model provides following technical solution：
A kind of bent axle positioning tool, including bent axle positioning seat, compact heap, limited block, mounting groove and regulation cock；The bent axle
There is the locating slot extended up and down on positioning seat；The bent axle positioning seat, which corresponds to, is connected with pilot pin on the side wall of locating slot, institute
It states compact heap to be connected on pilot pin, and compact heap can be rotated relative to pilot pin, and turns on the notch of locating slot；Institute
State the top that mounting groove is set to bent axle positioning seat；The limited block sliding is matched in mounting groove, and has limit on limited block
Slot；There is the bent axle positioning seat mounting plate, the regulation cock screw-thread fit to be connected to mounting plate on the side wall of locating slot
On, and the end of regulation cock extend into mounting groove with limited block against.
Preferably, the mounting groove is made of two pieces of guide plates and one piece of top plate, and two pieces of guide plates are arranged in parallel, and bottom plate connects
It is connected to the upper surface of two guide plates.
Preferably, threaded hole is offered on the top plate, and fastening bolt, the lower end of the fastening bolt are equipped in the threaded hole
It is resisted against on limited block across top plate.
The advantages of the utility model is：When fixed crankshaft, the front end of bent axle is placed in locating slot, compact heap is rotated, makes
Bent axle is pressed in locating slot by compact heap, and the crank arm of bent axle coordinates in limiting slot, and circumferential direction and axis are played to bent axle
To position-limiting action, to play the role of stablizing to bent axle it is fixed；On the other hand, regulation cock can adjust limited block and pacify
Position in tankage, pilot pin can adjust the elasticity of compact heap, are fixed, carry to various sizes of bent axle to realize
The flexibility that the utility model uses is risen, therefore the utility model is not only simple in structure, and used simply, flexibly, significantly
Improve the efficiency fixed, drilled to bent axle.
Description of the drawings
The schematic diagram for the bent axle positioning tool that Fig. 1 is provided by the present embodiment；
The side view for the bent axle positioning tool that Fig. 2 is provided by the present embodiment.
Specific implementation mode
The utility model bent axle positioning tool is further described by Fig. 1 to Fig. 2.
A kind of bent axle positioning tool, including bent axle positioning seat 1, compact heap 2, limited block 5, mounting groove 4 and regulation cock 10；Institute
State the locating slot 11 for having on bent axle positioning seat 1 and extending up and down；Have on the side wall of the correspondence of bent axle positioning seat 1 locating slot 11
Threaded connection hole is connected with pilot pin 3 in threaded connection hole, and the compact heap 2 is connected on pilot pin 3, and 2 energy of compact heap
It rotates, and is turned on the notch of locating slot 11 relative to pilot pin 3, when the various sizes of bent axle of fixation, pilot pin 3 passes through
Screw-thread fit setting adjusts the elasticity of compact heap 2, to adapt to the fixation of various sizes of bent axle；The mounting groove 4 is set to song
The top of axis positioning seat 1；The sliding of the limited block 5 is matched in mounting groove 4, and has limiting slot 51 on limited block 5；The song
Axis positioning seat 1 forms mounting plate 9 on the side wall of locating slot 11, and 10 screw-thread fit of the regulation cock is connected to mounting plate 9
On, i.e., there is threaded connection hole, 10 screw-thread fit of regulation cock is in threaded connection hole, and the end of regulation cock 10 on mounting plate 9
Portion extends into mounting groove 4 with limited block 5 against playing the role of limit to limited block 5, to realize limited block 5 to song
The positioning of axis.
Further, the mounting groove 4 is made of two pieces of guide plates 6 and one piece of top plate 7, and two pieces of guide plates 6 are arranged in parallel,
Bottom plate is connected to the upper surface of two guide plates 6, this is simple in structure, stable, and use aspect, is convenient for the operation of staff.
Further, threaded hole is offered on the top plate 7, and fastening bolt 8, the fastening bolt 8 are equipped in the threaded hole
Lower end be resisted against on limited block 5 across top plate 7, which can play the effect compressed to limited block 5, further to carry
Stability of the high limited block 5 in mounting groove 4 realizes effective limit of the limited block 5 to bent axle.
Further, for compact heap 2 towards having inclined surface on the side wall of locating slot 11, which can facilitate compact heap
2 turn on bent axle, and bent axle is compressed.
Further, there is handle 21, the handle 21 can facilitate the rotation of compact heap 2 on compact heap 2.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
