Embodiment Construction

[0028] A kind of eccentric lug puller of the present invention, as Figure 1-11 As shown, it includes a drawing rod 1, the drawing rod is a screw whose axis extends in the vertical direction, and the lower end of the drawing rod is provided with an eccentric disk perpendicular to the direction of the axis. The eccentric hanging lug 5 is installed on the above-mentioned drawing rod 1, and the eccentric hanging lug 5 and the pulling rod can be rotated relatively. ear. The eccentric disc has an installation station that turns into the projection of the eccentric lug in the up and down direction and a drawing station that is used to hang and pull the right end surface of the workpiece after turning out the projection of the eccentric lug.

[0029] The above-mentioned eccentric hanging lug is a sleeve-shaped structure extending in the up-down direction, and the above-mentioned hanging lug is arranged on the lower side of the eccentric hanging lug and extends radially along the val...

Abstract

The invention relates to an eccentric hanger drawing machine. The eccentric hanger drawing machine comprises a drawing rod with axle extending in the vertical direction, wherein an eccentric disc is arranged at the lower end of the drawing rod; the drawing rod is provided with an eccentric hanger capable of rotating corresponding to the drawing rod; the eccentric hanger is positioned above the eccentric disc, and has a hanger part for hanging the left side end surface of a workpiece; and the eccentric disc has an installation station for shifting in a projection of the eccentric hanger in the vertical direction, and a drawing station for shifting out the projection of the eccentric hanger in the vertical direction to hang the right side end surface of the workpiece. The eccentric hanger drawing machine can easily install in the drawing rod and the eccentric hanger, is convenient for installation, has no need to be smashed, prevents the damage, prolongs the service life, and also prevents the deformation or the damage of a frame type structure for installing the workpiece. Users can judge if the eccentric disc and the eccentric hanger are firmly connected with the workpiece through vertically lifting the drawing rod, so that both time and labor are saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a mechanical disassembly device, in particular to an eccentric lug puller. Background technique [0002] Chinese patent document CN201824115U discloses a bearing removal device, which includes a positioning sleeve, an adjusting sleeve and a pull rod shaft. The left end of the pull rod shaft is provided with an eccentric disk, and the above-mentioned positioning sleeve is rotatably assembled on the pull rod shaft on the right side of the eccentric disk. The right end of the pull rod shaft is sheathed with a pressing plate, and the pressing plate is matched with a nut that is screw-mounted on the right end of the pull rod shaft, and two bolts are also screw-mounted on the pressing plate. When in use, select the corresponding adjustment sleeve according to the specification of the bearing, and put the adjustment sleeve outside the positioning sleeve, then install the above-mentioned bearing removal device into the inner hole of th...
