Description
Technical field
The present invention relates to the indexs such as throw of crank shaft, bounce, the depth of parallelism are used when being detected on flat board
Bent axle adjustable trestle.It is contour that this support can quickly adjust bent axle supported on both sides center line of journal.In order to detect bent axle
The indexs such as throw of crankshaft, bounce, the depth of parallelism.
Background technology
Existing tractor crankshaft support is a V shape iron support, is placed in detection platform by two a pair points during use
Not Zhi Cheng bent axle both ends axle journal, then detect two support center line of journal it is whether contour, if not contour that center line is low
Side bent axle lift, removed V shape iron support manually, clearance gauge inserted between V shape iron cradle bottom surface and detection platform, is then put down
Bent axle, two are detected again and supports center line of journal whether contour, is adjusted repeatedly untill contour if not contour.
Big shape bent axle, particularly pier forging bent axle volume is big, and weight is big, relatively difficult to remove, lift by manpower in detection process,
Often lifted by crane using crane, it is troublesome in poeration, it is time-consuming, it has not been convenient to.This lean against inserts plug between V shape iron cradle bottom surface and detection platform
Chi supports the contour modes of center line of journal to adjust two, and human factor influence error is larger, and labor intensity is big, adjustment time
It is long.Need to rotate bent axle in addition, the support of V shape iron and maneton coordinates, during detection, crank rotation resistance is big, is also not easy to song
Shaft detection.
The content of the invention
It is an object of the invention to provide a kind of simple in construction, manufacture simplicity, tractor crankshaft adjustable trestle easy to use.
It is contour that the support can quickly adjust bent axle supported on both sides center line of journal in time, in order to carry out throw of crankshaft to bent axle, jump
The Indexs measures such as the dynamic, depth of parallelism.
Tractor crankshaft adjustable trestle of the present invention is adjusted by base 1, V shapes iron 2, left-right rotation support roller 4a, 4b, height
Screw push rod 3 and its locking nut 5 are formed；
The lower end side of V shapes iron 2 is articulated and connected with the hinged block 10 opened up on base 1 by hinge 11, V shapes iron 2
Opposite side lower end is provided with stopping table 20, and screw push rod 3 and its locking nut 5, screw are provided with the table top 20a of the stopping table 20
The bottom of push rod 3, which is acted on the upper surface of base 1 and V shapes iron 2 is rotated centered on hinge 11, lifts the height of regulation V shapes iron 2, in V
Installation left-right rotation support roller 4a, 4b respectively, left-right rotation support roller 4a, 4b are symmetrical arranged at left and right sides of the V-shaped groove of shape iron 2
The V-shaped groove face and maneton for substituting V shapes iron 2 coordinate support.
The present invention is simple in construction, and manufacture is easy, easy to use, can be at any time by screw push rod 3 to V shapes iron 2 during use
Highly it is adjusted, makes two of bent axle to support center line of journal contour, left-right rotation support roller 4a, 4b on V shapes iron 2
The V-shaped groove face and maneton for substituting V shapes iron 2 coordinate support, bent axle is rotated in detection easy and convenient.

Embodiment
Tractor crankshaft adjustable trestle of the present invention is adjusted by base 1, V shapes iron 2, left-right rotation support roller 4a, 4b, height
Screw push rod 3 and its locking nut 5 are formed；The lower end side of V shapes iron 2 passes through hinge 11 with the hinged block 10 opened up on base 1
It is articulated and connected, the opposite side lower end of V shapes iron 2 is provided with stopping table 20, and screw push rod 3 is provided with the table top 20a of the stopping table 20
And its locking nut 5, the bottom of screw push rod 3, which is acted on the upper surface of base 1 and V shapes iron 2 is rotated centered on hinge 11, lifts tune
The height of V shapes iron 2 is saved, installation left-right rotation support roller 4a, 4b respectively is symmetrical arranged at left and right sides of the V-shaped groove of V shapes iron 2,
Left-right rotation support roller 4a, 4b substitutes the V-shaped groove face of V shapes iron 2 and maneton coordinates support.
Shown in accompanying drawing embodiment, left-right rotation support roller 4a, 4b is respectively by being fixedly mounted on the V-shaped groove both sides of V shapes iron 2
Bearing pin 41, the cylinder rolling bearing 42 on bearing pin 41, the structure of bearing outside 43 being fixedly mounted on rolling bearing 42
Into.The setting of bearing outside 43 can prevent bearing from directly supporting with maneton to coordinate abrasion, be conveniently replaceable maintenance.
Respectively with rotational support roller 4a, 4b and the maneton of crankshaft two end on this support V shapes iron 2 when the present invention uses
Coordinate support, detect two and support center line of journal whether contour, if not contour, V shapes iron 2 is pressed in lever indicator
On the table top 20a of stopping table 20 or on maneton surface, coordinated with the hexagonal prism 31 opened up on spanner and screw push rod 3 and turned
Dynamic screw push rod 3 is adjusted, after making bent axle supported on both sides center line of journal contour, the locking nut 5 of lock screw push rod 3,
Start to detect.
