Description
Technical field
The utility model relates to tractor crankshaft devices, and in particular to a kind of tractor crankshaft bracket.
Background technique
Crankshaft 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.Crankshaft is by the centrifugal force of gyrating mass, the gas inertia of mechanical periodicity
The collective effect of power and reciprocal inertia force makes crankshaft bear the effect of flexion torsion load.Existing tractor crankshaft bracket is
One V shape iron bracket, when use, are placed on the both ends axle journal for supporting crankshaft in detection platform respectively by two a pair, then detect two
Whether a support center line of journal is contour, if the not contour side crankshaft that center line is low lifts, has removed V shape iron branch manually
Frame is inserted into clearance gauge between V shape iron cradle bottom surface and detection platform, then puts down crankshaft, detects two support journal centre again
Whether line is contour, is adjusted until contour repeatedly if not contour.
Big shape crankshaft, especially pier forging crankshaft volume is big, and weight is big, removed in detection process by manpower, lift it is relatively difficult,
Often lifted by crane using crane, it is troublesome in poeration, it is time-consuming, it has not been convenient to.This lean against is inserted into plug between V shape iron cradle bottom surface and detection platform
Ruler adjusts two contour modes of support center line of journal, and it is larger that human factor influences error, large labor intensity, adjustment time
It is long.In addition, V shape iron and maneton support cooperate, when detection, needs to rotate crankshaft, and 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 tractor crankshaft bracket, the detection support bracket can in time quickly
The height for adjusting crankshaft axle journal supported on both sides, is convenient for detecting.
In order to achieve the above objectives, the base case of the utility model is as follows: tractor crankshaft bracket: including pedestal, the bottom
Seat is equipped with the first V-block and the second V-block, is all provided on first V-block and the second V-block there are two rotational support roller,

The sliding rail is equipped with first baffle and second baffle, and the first baffle and second baffle are located at the first V-block and the
Above two V-blocks, RF transmitter is equipped with above the first baffle, the second baffle, which is equipped with, can receive infrared ray hair
Emitter emits the infrared receiver of signal, and the pedestal is equipped with slot, and the slot top is rotatably connected to screw element, institute
It is affixed to state screw rod one end and the first V-block lower end, the screw rod other end passes through screw element and slot and matches with screw element screw thread
It closes.
Using this base case working principle and have the beneficial effect that: when specifically used, crankshaft is placed on the first V
On type block and the second V-block, and first baffle and second baffle are slided along sliding rail, first baffle is made to offset with the first V-block, the
Two baffles offset with the second V-block.Start RF transmitter.If two axle journal height of crankshaft are identical, then first gear
The height of plate and second baffle be also it is equal, at this time RF transmitter transmitting infrared ray can be connect by infrared receiver
It receives, directly crankshaft is detected.If the height of two axle journals of crankshaft is different, RF transmitter emits infrared
Line will not be received by infrared receiver, at this point, rotation screw element is turning because screw element and screw flight cooperate
When dynamic screw element, screw rod can axially generate displacement along this, that is, change the height of the first V-block, until infrared receiver receives
The infrared ray emitted to RF transmitter.Two axle journals height of crankshaft is identical, can detect to crankshaft.
It further, further include buzzer, the buzzer is electrically connected with infrared receiver.When infrared receiver receives
After the infrared ray emitted to RF transmitter, buzzer is transmitted signals to, buzzer makes a sound prompt people.
It further, further include rotating bar, described rotating bar one end is connect with screw element, screw element is rotated by rotating bar,
It is easy to operate, it is laborsaving.
Further, the rotating bar includes connecting rod, ring set and lantern ring, is equipped in the ring set and mutually fits with screw element shape
The inner hole matched, the ring set outer wall are circumferentially with groove, and the lantern ring is slidably connected by groove and ring set；The groove inner wall
Equipped with multiple slots, described connecting rod one end is connect with lantern ring；The hollow setting of the connecting rod and internal slide is connected with connection
Column, the connecting column can be plugged into slot；The connecting rod upper end slidably connects skewback, the connecting column be equipped with it is oblique
The baltimore groove that block offsets.It when in use,, then can be by one in the slot that the end of connecting column is protruded under reset condition
Direction is rotatablely connected bar, makes connecting rod that lantern ring and ring set be driven to rotate together, because inner hole is adapted with screw element shape
To drive screw element to rotate, achieve the effect that adjust height.When the circle number for needing to rotate is more, skewback, skewback can be pressed
It slides down in baltimore groove, under the action of skewback, connecting column is slid back, and connecting column is not extend into slot, and rotation connects
Extension bar then only drives lantern ring rotation, ring set will not be made to rotate, can rotate screw element back and forth, be particularly suitable for turn
The case where 360 ° dynamic.
Further, elastic component is equipped between the connecting column and connecting rod inner wall, setting elastic component returns to just convenient for connecting column
Beginning position.
Further, the elastic component is pressure spring, and spring is easy to obtain.
