Abstract
The invention provides an adjustable bracket for crankshaft detection. The adjustable bracket is composed of a base (1), V-shaped iron (2), a left rotating supporting roller (4a), a right rotating supporting roller (4b), a height adjusting screw jacking rod (3) and a locking nut (5); one side of the lower end of the V-shaped iron (2) is hinged to the base (1), the lower end of the other side of the V-shaped iron (2) is provided with the screw jacking rod (3) which acts on the upper surface of the base (1) to adjust the height of the V-shaped iron (2), and the left side and the right side of a V-shaped groove of the V-shaped iron (2) are symmetrically arranged and provided with the left rotating supporting roller (4a) and the right rotating supporting roller (4b) respectively for being matched with a crankshaft neck for supporting.
Description
Technical field
The present invention relates to throw of crank shaft, beat, the index such as the depth of parallelism uses when detecting 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.So that detection bent axle
Throw of crankshaft, 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.
Summary 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 this support can the most quickly adjust bent axle supported on both sides center line of journal, in order to bent axle is carried out throw of crankshaft, jumping
The Indexs measure such as dynamic, the depth of parallelism.
Tractor crankshaft adjustable trestle of the present invention is supported roller 4a, 4b, altitude mixture control by base 1, V shape ferrum 2, left-right rotation
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, another of V shape ferrum 2
Lower end, side has stopping table 20, is provided with screw push rod 3 and locking nut 5 thereof, screw push rod on the table top 20a of this stopping table 20
3 bottoms 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 shape ferrum
The left and right sides of the V-shaped groove of 2 is symmetrical arranged and is respectively mounted left-right rotation support roller 4a, 4b, and left-right rotation supports roller 4a, 4b and substitutes
The V-shaped groove face of V shape ferrum 2 coordinates support with maneton.
Present configuration is simple, manufactures simplicity, easy to use, can be reached by screw push rod 3 to V shape ferrum 2 during use
Highly being adjusted, 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
The V-shaped groove face substituting V shape ferrum 2 coordinates support with maneton, makes bent axle rotate when detection easy and convenient.

Detailed description of the invention
Tractor crankshaft adjustable trestle of the present invention is supported roller 4a, 4b, altitude mixture control by base 1, V shape ferrum 2, left-right rotation
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 11
Being articulated and connected, the opposite side lower end of V shape ferrum 2 has stopping table 20, is provided with screw push rod 3 on the table top 20a of this stopping table 20
And locking nut 5, screw push rod 3 bottom acts on base 1 upper surface and makes V shape ferrum 2 rotate centered by hinge 11 to lift tune
Joint V shape ferrum 2 height, is symmetrical arranged in the left and right sides of the V-shaped groove of V shape ferrum 2 and is 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 maneton of rotational support roller 4a, the 4b on this support V shape ferrum 2 Yu crankshaft two end when the present invention uses
Coordinate and support, detect two support center line of journal the most contour, if the most contour, be pressed in V shape ferrum 2 with lever indicator
On the table top 20a of stopping table 20 or on maneton surface, coordinate with the hexagonal prism 31 offered on screw push rod 3 with spanner and turn
Dynamic screw push rod 3 is adjusted, after making bent axle supported on both sides center line of journal contour, and the locking nut 5 of lock screw push rod 3,
Start detection.
