Description
Technical field
The present invention relates to a kind of instrument for being exclusively used in crane span structure pipe orifice bearing dismantling.
Background technology
Include front axle assy and rear axle assy in the chassis suspension of automobile, front axle assy and rear axle assy are generally all
Can have a crane span structure pipe, installation endoporus needle bearing in the pipe of crane span structure pipe, endoporus needle bearing due to a distance from the mouth of pipe often compared with
Far, so dismounting is very inconvenient.
The content of the invention
In view of the deficiencies in the prior art, the technical problem to be solved in the present invention is be that providing one kind is exclusively used in crane span structure pipe
The dismounting that hole axle is held, easy to operate crane span structure pipe orifice bearing assembling-disassembling tools simple in structure.
The present invention is adopted the following technical scheme that to complete：
Crane span structure pipe orifice bearing assembling-disassembling tools, it is characterised in that：Including symmetrically arranged left and right pull rod, it is equipped between the pull rod of left and right
Spring, the lowermost end of left and right pull rod are equipped with the pawl head of outside 90 degree bendings, and left and right pull rod is equipped with spiral shell in the position close to upper rod end
Card, thread plate allow left and right pull rod activity to pass through equipped with left and right fenestra, positioning pin are equipped with the fenestra of left and right, it is fixed that left and right pull rod passes through
Position pin is rotatablely connected with thread plate, and the center of thread plate, which is equipped with, adjusts threaded hole, adjusts threaded hole internal thread and is screwed with adjusting spiral shell
Bar, the top of thread plate are equipped with limiting plate, and the center of limiting plate is worn equipped with spacing window by adjusting screw rod and left and right pull rod activity
Cross, the upper rod end of left and right pull rod is equipped with spacer pin, and spacer pin blocks limiting plate from upper side direction, and the side of limiting plate is equipped with positioning
Screw, positioning screw are threadedly connected on limiting plate, the head face pull rod of positioning screw.
The crane span structure pipe orifice bearing assembling-disassembling tools of above-mentioned technical proposal, simple in structure easy to operate, specific operation process is：
Left and right pull rod is extend into crane span structure pipe orifice first, and compressing spring makes the bottom of left and right pull rod close to each other, then left and right is drawn
The bottom of bar and pawl head reach the lower face of needle bearing by the endoporus of needle bearing, and then pull-off spring makes left and right pull rod remote
From at this moment by turning positioning screw come pushing drawing rod, making the opening distance of pull rod lower end suitable, then the pawl head of left and right pull rod
The lower face of needle bearing can be reliably held from bottom direction, at this moment tightens adjusting screw rod（Before adjusting screw rod is tightened, first
Plate is placed against in the nozzle position of crane span structure pipe, allows the lower rod end of adjusting screw rod to offset with abutment plate）, thread plate can be driven upward
Mobile, then left and right pull rod little by little pulls up needle bearing, until needle bearing can easily take from the endoporus of crane span structure pipe
Go out.
Brief description of the drawings
The present invention has drawings described below：
