Description
Technical field
The utility model relates to a kind of devices for replacing withdrawal straightening machine roller bearing, belong to the maintenance of metallurgy industry tension leveller of continuous casting machine
Tool equipment technical field of tools.
Background technique
Currently, in 100 tons of tension leveller of continuous casting machine repair procedures, since the replacement of roller bearing is without specific purpose tool, only
Installation exercise can be struck by manually hammer.Manually hammer strikes installation exercise, is easily damaged bearing, and installs a dish axle and hold
Need 5 people that could complete 2 hours, operating rate is extremely low；In addition, there is also some potential safety problems, works for hammering installation bearing
People's large labor intensity, and it is easy to happen industrial accident.
Utility model content
The utility model aim is to provide a kind of device for replacing withdrawal straightening machine roller bearing, being capable of quickly and easily more roll change
Sub- bearing is effectively reduced labor intensity of workers, guarantees safety in production, solves the problems, such as background technique.
The technical solution of the utility model is:
A kind of device for replacing withdrawal straightening machine roller bearing includes fixed baffle, roller, roller support, hydraulic cylinder cylinder head, liquid
Cylinder pressure and hydraulic cylinder hold-down support, roller are located on roller support, and one end of roller is equipped with fixed baffle, and the other end of roller is set
There is hydraulic cylinder, the hydraulic cylinder is fixed on hydraulic cylinder hold-down support, and hydraulic cylinder connects the liquid matched with roller bearing
Cylinder pressure cylinder head, the hydraulic cylinder cylinder head are ladder circle column type, and the lesser one end of hydraulic cylinder cylinder head diameter is threadedly coupled with hydraulic cylinder,
The center of one end that hydraulic cylinder cylinder head is relatively large in diameter is equipped with a blind hole.
The outer diameter of one end that the hydraulic cylinder cylinder head is relatively large in diameter is less than the diameter of roller bearing outer ring, and hydraulic cylinder cylinder head is straight
The diameter of blind hole of the biggish one end of diameter is greater than the diameter of roller bearing inner ring.
The center line of the center line of the hydraulic cylinder cylinder head and roller is on the same line.
The bearing block for installing roller bearing is placed on when replacing withdrawal straightening machine roller bearing by roller using the utility model
Shaft end starts hydraulic cylinder, roller bearing is installed to roller bearing using the pressure of hydraulic cylinder travel, and by hydraulic cylinder cylinder head
Hydraulic cylinder cylinder head after roller bearing is installed in place, is withdrawn in end face.
The beneficial effects of the utility model are: the pressure and hydraulic cylinder cylinder head using hydraulic cylinder travel install roller bearing
In place, damage bearing no longer is avoided with the method for user's work hammering installation, and a dish axle is installed and is held by 5 original people 2
A hour, bearing installation exercise can be completed in people 10 minutes by only needing 2 now.Structure is simple and convenient to operate, and improves work
Make efficiency, alleviate the labor intensity of worker, while avoiding the generation of industrial accident.

Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1-5, a kind of device for replacing withdrawal straightening machine roller bearing includes fixed baffle 1, roller 2, roller support
5, hydraulic cylinder cylinder head 7, hydraulic cylinder 8 and hydraulic cylinder hold-down support 9, roller 2 are located on roller support 5, and one end of roller 2 is equipped with solid
Determine baffle 1, the other end of roller 2 is equipped with hydraulic cylinder 8, and the hydraulic cylinder 8 is fixed on hydraulic cylinder hold-down support 9, and hydraulic cylinder 8 connects
The hydraulic cylinder cylinder head 7 matched with roller bearing is connect, the hydraulic cylinder cylinder head 7 is ladder circle column type, and hydraulic cylinder cylinder head 7 is straight
The lesser one end of diameter is threadedly coupled with hydraulic cylinder 8, and the center of one end that hydraulic cylinder cylinder head 7 is relatively large in diameter is equipped with a blind hole.
In the present embodiment, fixed baffle 1 and roller support 5 are according to being welded on one after 2 length of roller and elevation carrection
On workbench, hydraulic cylinder hold-down support 9 is welded on another workbench, and the main function of hydraulic cylinder hold-down support 9 is solid
Determine hydraulic cylinder 8, make in its work not play, the center line of the center line of hydraulic cylinder cylinder head 7 and roller 2 is on the same line.
Referring to attached drawing 3,4,5, the outer diameter of one end that hydraulic cylinder cylinder head 7 is relatively large in diameter is less than the diameter of 4 outer ring of roller bearing
5mm, guarantees the outer ring that roller bearing 4 can be pushed down while do not contact with bearing block 3, hydraulic cylinder cylinder head 7 be relatively large in diameter one
The diameter of blind hole at end is greater than the diameter 5mm of 4 inner ring of roller bearing, and can push down the inner ring of roller bearing 4, and really not with axis
The contact of seat 3 is held, makes 4 Internal and external cycle of roller bearing in a plane, while being pushed into the abutting end of axis, does not damage bearing.
The specific work process of the utility model is as follows:
When installing roller bearing, first roller 2 is hung on the roller bracket 5 on platform, rear end is leaned on fixed baffle 1
It is real, the bearing block 3 for installing roller bearing 4 is placed at 2 front end spindle nose of roller, starting hydraulic cylinder 8 using hydraulic cylinder 8 makes liquid
Cylinder pressure cylinder head 7 installs positive roller bearing 4, after being installed in place, withdraws hydraulic cylinder cylinder head 7 and completes operation.
