Abstract

The utility model relates to a bearing puller which is characterized by comprising a puller body, wherein a first connecting piece and a second connecting piece are fixed on the puller body, the first connecting piece and the second connecting piece are respectively hinged with a clamping claw, the puller body is also provided with a jacking screw rod, the clamping claw comprises a first clamping part and a second clamping part, a clamping gap is formed between the first clamping part and the second clamping part, and a magnet is arranged on the upper end surface of the first clamping part and on the lower end surface of the second clamping part. The bearing clamping device realizes multi-point contact on the bearing through the first clamping part and the second clamping part, improves the clamping effect, and ensures that the bearing cannot be separated from the clamping claw by arranging the magnet to improve the attraction force.

Description

Bearing puller

Technical Field

The utility model relates to the technical field of mechanical tools, in particular to a bearing extractor.

Background

The traditional bearing extractor, namely the bearing puller, generally adopts 2 claws or 3 claws to pull the bearing sleeved on the shaft rod out through a screw rod, but the existing claws only have contact surfaces when contacting the bearing, and the bearing is easy to slide out when the clamping force to the bearing is insufficient in the extracting process.

Disclosure of Invention

The utility model aims to provide a bearing puller, which improves the clamping effect between a bearing and a clamping jaw.

In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a bearing extractor, its characterized in that, includes the extractor body, be fixed with first connecting piece and second connecting piece on the extractor body, first connecting piece and second connecting piece articulate respectively has the chucking claw, the extractor body still is provided with the tight screw rod in top, the chucking claw includes first clamping part and second clamping part, form the chucking clearance between first clamping part and the second clamping part, wherein the lower terminal surface of the up end box second clamping part of first clamping part is provided with magnet.

The utility model is further provided with a rotating shaft arranged between the clamping claw and the first connecting piece and between the clamping claw and the second connecting piece, and the rotating shaft is provided with a first screwing nut and a second screwing nut.

The utility model has the beneficial effects that: the bearing clamping device realizes multi-point contact on the bearing through the first clamping part and the second clamping part, improves the clamping effect, and ensures that the bearing cannot be separated from the clamping claw by arranging the magnet to improve the attraction force.
