Description
Technical field
The utility model is related to one kind being used for the fixed frock clamp of bent axle.
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 the end trepanning in crank arm, it is therefore desirable to which crank is fixed.Existing skill
In art, it is used for the complicated of the tooling of fixed crankshaft, it is inconvenient to use, cause the drilling efficiency of bent axle relatively low, therefore exist
Improved space.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of for the fixed frock clamp of bent axle.
To achieve the above object, the utility model provides following technical solution：
One kind being used for the fixed frock clamp of bent axle, including bottom plate, bent axle positioning seat, crossbeam, cylinder and compression bar；The song
Axis positioning seat is installed on bottom plate, has locating slot on bent axle positioning seat；The crossbeam is fixedly installed in the top of bottom plate, described
Cylinder is installed on crossbeam, and the compression bar is connected on the piston rod of cylinder, and is moved up and down with piston rod, under the compression bar
Surface has compact heap, and compact heap is correspondingly arranged up and down with locating slot.
Preferably, there is limiting plate, the limiting plate to be located at wherein one end of locating slot on the bent axle positioning seat.
Preferably, screw-thread fit is connected with Limit screw on the limiting plate.
Preferably, the compact heap and bent axle positioning seat all have multiple, and compact heap is corresponded with bent axle positioning seat.
Preferably, the lower surface of the compact heap has mating groove, and the section of the mating groove is arc-shaped setting.
Preferably, it is threaded with cushion block on the side wall of the locating slot.
The advantages of the utility model is：In use, bent axle is positioned in locating slot, cylinder driving compression bar moves down,
So that compact heap compresses the bent axle in locating slot, to realize the fixation of bent axle, due to the structure of frock clamp during being somebody's turn to do
It is relatively simple, and using more convenient, therefore improve the efficiency that bent axle is fixed and drills.
Description of the drawings
The schematic diagram for the fixed frock clamp of bent axle that Fig. 1 is provided by the present embodiment.
Specific implementation mode
The utility model is further described for the fixed frock clamp of bent axle by Fig. 1.
One kind being used for the fixed frock clamp of bent axle, including bottom plate 1, bent axle positioning seat 2, crossbeam 8, cylinder and compression bar 6；Institute
It states bent axle positioning seat 2 and is bolted and be installed on bottom plate 1, there is locating slot 21 on bent axle positioning seat 2；The crossbeam 8 is solid
Dingan County is loaded on the top of bottom plate 1, i.e. the crossbeam 8 can be located at the top of bottom plate 1 by way of being installed on rack, can also lead to
Column to be crossed to be installed on bottom plate 1, the cylinder is fixedly installed on crossbeam 8, and the compression bar 6 is connected on the piston rod 9 of cylinder,
And moved up and down with piston rod, the lower surface of the compression bar 6 has compact heap 7, and compact heap 7 is corresponding with about 21 locating slot sets
It sets, after cylinder pushes compression bar 6 to move down, compact heap 7 can compress the bent axle in locating slot 21.
Further, the section of the locating slot 21 is arranged for triangle, which can be to bent axle in locating slot 21
Play the role of left and right limit, so that the fixation of bent axle is more stable.
Further, there is limiting plate 4, the limiting plate 4 to be located at wherein the one of locating slot 21 on the bent axle positioning seat 2
End, the limiting plate 4 can play the role of the axial direction of bent axle limit, improve the fixed stability of bent axle.
Further, screw-thread fit is connected with Limit screw 5 on the limiting plate 4, i.e., has threaded hole on limiting plate 4,
Limit screw 5 is matched in threaded hole, and Limit screw 5 is located along the same line with locating slot 21, and Limit screw 5 being capable of basis
The physical length of bent axle is adjusted in threaded hole, the fixation to various sizes of bent axle is realized, to improve this practicality
The novel flexibility used.
Further, the compact heap 7 and bent axle positioning seat 2 all have multiple, and compact heap 7 and bent axle positioning seat 2 one
One corresponds to, which can simultaneously compress multiple bent axles, to improve the efficiency of crankshaft drilling.In the present embodiment, one
There are two pieces of compact heaps 7, therefore corresponding there are two bent axle positioning seat 2 on root compression bar 6, two pieces of compact heaps 7 are located at the two of compression bar 6
End.
Further, the lower surface of the compact heap 7 has mating groove 71, and the section of the mating groove 71 is arc-shaped sets
Set, arc-shaped setting can increase the contact area of mating groove 71 and bent axle, can improve the stability that bent axle is compressed and
Mating groove 71 is reduced by the probability of bent axle part crushing.
Further, it is threaded with cushion block 3 on the side wall of the locating slot 21, which can play bent axle into one
The protective effect of step.
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
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the scope of protection of the utility model.It should refer to
