Abstract
The invention relates to a press-mounting tool for disassembling and assembling tightly matched pin shafts, which forms a closed square frame by the connection of a steel plate and a track. A jack is placed in the square frame, the head of the jack applies a pressure on a pin shaft, the tail of the jack applies a pressure on the track, the pressure born by the track forms a supporting force on the pin shaft by the transfer of a pulling plate, and the pin shaft can be dismounted.
Description
Technical field
Removing and installing of the practical bearing pin of this specific purpose tool makes bearing pin injury-free when dismounting or installation, improves operating efficiency simultaneously and reduces cost.
Background technology
Removing and installing of present bearing pin, generally the method for directly beaing with sledgehammer causes bearing pin to pound riveting easily and damages bearing pin and hole quality of fit height, dismounting is difficulty relatively, in addition, owing to be subjected to the influence of ambient temperature, bearing pin expands, and the gap in bearing pin and hole is littler, makes troubles for the dismounting bearing pin.
Summary of the invention
For fast quick-detach or installation bearing pin, the utility model provides a kind of specific purpose tool, this instrument quick release or installation bearing pin, do not damage bearing pin when guaranteeing dismounting or installation simultaneously, guarantee the installation accuracy of bearing pin, improve operating efficiency, reduce recondition expense and labour intensity.
The method that this new tool solves the dismounting bearing pin is: with (1) two both sides that are welded on fixed pin shaft respectively of thick 20mm steel plate, thick 20mm steel plate (4) is fixed on the steel plate (1) with M30 bolt (2), track (3) with 43kg/m is through in the hole, with jack (5) ejector pin axle (6) outward, when the stroke of jack is not enough, withdraw from jack, track is moved a hole forward or backward, use jack ejector pin axle again,, realize dismounting or bearing pin is installed by the position of moving track.
The advantage of this new tool is; When dismounting or installation bearing pin, steel plate (4) is installed, the steel plate (4) of dismantling after installation or removal finish, unaffected when guaranteeing the equipment operation, when dismounting or installation bearing pin, jack dismounting bearing pin is stressed evenly, guarantee that bearing pin is not damaged, guarantee the installation accuracy of bearing pin, improve overhaul efficiency, reduce labour intensity.
Description of drawings:
Fig. 1 is the steel plate connection layout, and Fig. 2 is this tool construction schematic diagram
(1) steel plate (2) bolt (3) 43kg/mg track (4) steel plate (5) jack (6) bearing pin
The specific embodiment:
Use three bolts (2) to be connected respectively steel plate (1) and steel plate (4) as shown in the figure, track (3) is inserted in the hole, make entire tool form the square frame of a closure, at last hydraulic jack (5) is put into the square frame center, its head is withstood on the axle, afterbody withstands on the track, the pressure of jack can be become the top power to bearing pin.
Claims (1)
1. the extracting tool of a bearing pin is made up of two block plates, one on one, 32 tons jack of one meter track, 6 on the bolt of band attachment rail base.It is characterized in that: the steel plate by being welded on the bearing pin both sides and splicing, plug-in mounting such as two steel plates of belt track jack and track form a closure frame, and the pressure of jack is converted into top power to bearing pin.
