Description

one

The invention relates to the field of hand tools for disassembling press joints and can be used in assembling new machines and especially in repairs when it becomes necessary to disassemble a previously made press connection.

A puller is known comprising a traverse, legs for gripping the part to be disassembled, fixed at the ends of the traverse, a crosspiece, pivotally connected to the traverse, and an adjustable stop.

In order to increase the effort of moving. The proposed puller is provided with levers interconnected with an emphasis and a crosspiece by means of bows and forming a power parallelogram.

FIG. 1 shows the proposed puller, front view; in fig. 2 - the same, side view.

The puller contains a crosspiece 1, ti 2, pivotally connected to the crosspiece, traverse 3, pivotally connected by means of tg 2 to the crosspiece /, paws 4 for gripping the part to be disassembled, stop 5 with a screwed-in stop screw 6, nut 7, sleeve 8, working screw 9, retaining ring 10, levers 11, forming a power parallelogram. When rotating the working screw 9 force

repressing through a system consisting of a screw 9, levers 11 forming a power parallelogram, t g 2, traverse 3, stop 5 and paws 4, is transmitted to the parts to be dismantled. Depending on the thickness of the removed parts

the length of the anvil 5 is adjusted by the stop screw 6.

Subject invention

The puller containing the crosshead, paws for gripping the part to be disassembled, fastened to the ends of the crosshead, a crossbar pivotally connected by means of a pull to the crosshead, and an adjustable stop, characterized in that

in order to increase the removal force, it is equipped with levers interconnected with an emphasis and a crosspiece by means of hinges and forming a power parallelogram.
