Description
Technical field
The utility model relates to throw of crank shaft, beat, the index such as the depth of parallelism detect on flat board time
The bent axle adjustable trestle used.It is contour that this support can quickly adjust bent axle supported on both sides center line of journal.So that detection
Throw of crank shaft, beat, the index such as 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 point during use
Not supporting the two ends axle journal of bent axle, then detection two support center line of journal is the most contour, if the most contour that centrage is low
Side bent axle lift, manually removed V shape iron support, between V shape iron cradle bottom surface and detection platform insert clearance gauge, then put down
Bent axle, detection two support center line of journal is the most contour again, repeatedly adjusts until contour if the most contour.
Big shape bent axle, particularly pier forging bent axle volume are big, and weight is big, remove by manpower during detection, lift relatively difficult,
Crane is often used to lift by crane, troublesome poeration, time-consuming, it has not been convenient to.This leaning against inserts plug between V shape iron cradle bottom surface and detection platform
Chi adjusts two and supports the mode that center line of journal is contour, and it is relatively big that anthropic factor affects error, and labor intensity is big, adjusts the time
Long.Coordinating it addition, V shape iron supports with maneton, need to rotate bent axle during detection, crank rotation resistance is big, is also not easy to song
Shaft detection.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, manufactures simplicity, and tractor crankshaft easy to use is adjustable
Support.It is contour that this support can the most quickly adjust bent axle supported on both sides center line of journal, in order to bent axle carries out crank half
Footpath, beat, the Indexs measure such as the depth of parallelism.
This utility model tractor crankshaft adjustable trestle is supported roller 4a, 4b, highly by base 1, V shape ferrum 2, left-right rotation
Set screw push rod 3 and locking nut 5 thereof are constituted；
The hinged block 10 offered on the side, lower end of V shape ferrum 2 and base 1 is articulated and connected by hinge 11, V shape ferrum 2
Opposite side lower end has stopping table 20, is provided with screw push rod 3 and locking nut 5, screw on the table top 20a of this stopping table 20
Push rod 3 bottom act on base 1 upper surface make V shape ferrum 2 rotate centered by hinge 11 lift regulation V shape ferrum 2 height, at V
The left and right sides of the V-shaped groove of shape ferrum 2 is symmetrical arranged and is respectively mounted left-right rotation support roller 4a, 4b, and left-right rotation supports roller 4a, 4b
The V-shaped groove face substituting V shape ferrum 2 coordinates support with maneton.
This utility model simple in construction, manufactures simplicity, easy to use, can be reached by screw push rod 3 to V shape during use
The height of ferrum 2 is adjusted, and two the support center line of journal making bent axle are contour, and the left-right rotation on V shape ferrum 2 supports roller
4a, 4b substitute the V-shaped groove face of V shape ferrum 2 and coordinate support with maneton, make bent axle rotate when detection easy and convenient.

Detailed description of the invention
This utility model tractor crankshaft adjustable trestle is supported roller 4a, 4b, highly by base 1, V shape ferrum 2, left-right rotation
Set screw push rod 3 and locking nut 5 thereof are constituted；The hinged block 10 offered on the side, lower end of V shape ferrum 2 and base 1 is by hinge
Axle 11 is articulated and connected, and the opposite side lower end of V shape ferrum 2 has stopping table 20, is provided with screw on the table top 20a of this stopping table 20
Push rod 3 and locking nut 5 thereof, screw push rod 3 bottom acts on base 1 upper surface makes V shape ferrum 2 rotate centered by hinge 11
Lift regulation V shape ferrum 2 height, be symmetrical arranged in the left and right sides of the V-shaped groove of V shape ferrum 2 and be respectively mounted left-right rotation support roller
4a, 4b, left-right rotation supports the V-shaped groove face of roller 4a, 4b replacement V shape ferrum 2 and coordinates support with maneton.
Shown in accompanying drawing embodiment, left-right rotation supports roller 4a, 4b respectively by the V-shaped groove both sides being fixedly mounted on V shape ferrum 2
Bearing pin 41, the cylinder rolling bearing 42 being arranged on bearing pin 41, bearing outside 43 structure that is fixedly mounted on rolling bearing 42
Become.The setting of bearing outside 43 is possible to prevent bearing directly to coordinate abrasion with maneton support, it is simple to repair and replacement.
Respectively with the song of rotational support roller 4a, the 4b on this support V shape ferrum 2 Yu crankshaft two end when this utility model uses
Journal engagement supports, and detects two support center line of journal the most contour, if the most contour, is pressed in V shape ferrum with lever indicator
On the table top 20a of the stopping table 20 of 2 or on maneton surface, join with the hexagonal prism 31 offered on spanner and screw push rod 3
Close rotation screw push rod 3 to be adjusted, after making bent axle supported on both sides center line of journal contour, the locking screw of lock screw push rod 3
Female 5, start detection.
