Abstract
The utility model discloses a pin shaft removing device aiming to provide a pin shaft removing machine which is simple in structure, large in removing force, convenient to operate and makes workpieces and structures integrally pressed without deformation and damage. The utility model comprises an upper support, a lower support, a bushing, a hydraulic jack and a hand pressure device, or the like. The lower support is arranged in the upper support and relative shift motion exists between the two supports. The hydraulic jack is arranged between the upper support and the lower support, the lower support is flatwise arranged on the workpiece, the pin shafts of which is to be removed, the lower support is connected with the pin shafts to be removed by bolts. According to the load requirement of the pin shafts to be removed, the hydraulic jack is pressed until the pin shafts are removed. The utility model is suitable for pin shafts of various norms, in particular for long pin shafts and pin shafts which can be removed only from one direction.
Description
The utility model relates to a kind of bearing pin stripping attachment, especially is fit to the have strong market potential axle and the bearing pin that can only the single direction dismounting of interference fit.
In technique known, bearing pin on the detaching structure parts, especially dismantle interference fit major axis, be subjected to condition restriction can only single direction the bearing pin of dismounting, generally be disassembled the suitable framework of welding on the structural member of bearing pin, with jack or additive method, bearing pin is dismantled then., can influence the intensity of metal structure during lead frame, often monolateral stressed during operation, workpiece and structure easy deformation and impaired.
In order to overcome existing dismounting bearing pin method, monolateral stressed easily during operation, workpiece and structure easy deformation and impaired deficiency, the utility model provides a kind of bearing pin stripping attachment, dispose hydraulic jack between the upper and lower supporting of bearing pin stripping attachment, be connected with the bearing pin that is disassembled with bolt, operate manual pressue device, the dismounting bearing pin, simple in structure, easy to operate, during the bearing pin dismounting, workpiece and structural parts whole pressurized.
The technical scheme that its technical problem that solves the utility model adopts is: the bearing pin stripping attachment by upper support, lower support, hydraulic pressure thousand press closer, manual pressure device etc. forms.Lower support is enclosed within the upper support, certain stroke that relatively moves is arranged, the outer end of lower support lies on the workpiece or structure that is disassembled bearing pin, hydraulic jack is placed between the upper and lower supporting, with bolt with to be disassembled bearing pin and be connected, according to being disassembled the bearing pin burden requirement, pressurized hydraulic thousand presses closer, up to bearing pin is dismantled.
The beneficial effects of the utility model are: the utility model provides a kind of bearing pin stripping attachment, and is simple in structure, firm, and the scope that adapts to bearing pin is wide, and removal force is big, and is easy to operate, and during the bearing pin dismounting, workpiece and structural parts whole pressurized can not be out of shape with impaired.
Below in conjunction with accompanying drawing the utility model is further specified.
Figure is a bearing pin stripping attachment structure chart.
Upper support 1 lower support 2 hydraulic jack 3 bearing pins 4 manual augmentors 5 among the figure
Hexagon socket head cap screw 6 is disassembled structural member 7 linings 8 of bearing pin
In the drawings, the lower support cover 2 of bearing pin stripping attachment is 1 li of upper support, upper support 1 has certain shift motion relatively, the outer end of lower support 2 lies on the workpiece that is disassembled bearing pin or the structure 7, vertical or horizontal hydraulic jack 3 is placed between upper support 1 lower support 2, with hexagon socket head cap screw 6 with will be disassembled bearing pin 4 and couple together, according to being disassembled bearing pin 4 burden requirements, pressurized hydraulic jack 3, after lower support 2 strokes put in place, if bearing pin 4 is very long, earlier hydraulic pressure thousand is pressed closer 3 and lay down load, pull down hexagon socket head cap screw 6, add the lining 8 of certain altitude, with hexagon socket head cap screw 6 with will be disassembled bearing pin 4 and connect, continue pressurized hydraulic jack 3, again up to bearing pin is dismantled.
Claims (3)
1. the utility model discloses a kind of bearing pin stripping attachment, it by upper support, lower support, lining, hydraulic pressure thousand press closer, manual pressure device etc. forms, it is characterized in that the guide pad that Gong relatively moves is arranged in the upper support, lower support is enclosed within the upper support, lower support lies on the workpiece of split bearing pin, hydraulic pressure thousand presses closer and is placed between the upper and lower supporting, is connected with external manual pressure device, is connected with split bearing pin with bolt.
