A main cone lifting device

Abstract

The invention discloses a main cone lifting device, which is characterized in that a lifting air cylinder is arranged in a barrel body of an upper fixing pressing head, located at the bottom of a piston rod connecting seat of the upper fixing pressing head, and fixed in reversed mode. A three-jaw type shutter is arranged at the rod end of a piston rod of the lifting air cylinder, and the three-jaw type shutter is composed by a disk body fixed at the rod end of the piston rod and provided with annular clamping grooves, and three clamping jaws evenly distributed on the periphery of the disk body. The middle of each clamping jaw is hinged on the inner lateral wall of the upper fixing pressing head through hinge pins, the upper ends of the clamping jaws are clamped and fixed on the clamping grooves of the disk body, and the lower end of the clamping jaw surrounds the periphery of an upper shaft thread section of the main cone to form clamping on the main cone through elastic bodies fixed on the clamping jaws. The main cone lifting device enables the main cone to be lifted along with the lifting of the upper fixing pressing head.

Description

technical field [0001] The invention relates to a main cone lifting device, in particular to a main cone lifting device used in the press-fitting process of the inner ring of the main cone bearing of an axle. Background technique [0002] figure 1 and figure 2 Shown is the press-fitting process equipment for the inner ring of the axle main cone bearing in the prior art. The upper pressure head 8 is inserted into the upper fixed pressure head 1 and connected with bolts 11. The upper fixed pressure head 1 is connected with the piston rod connecting seat 2, and the piston rod The rod connection seat 2 pushes the upper fixed pressure head 1 and the upper pressure head 8 to press the lower bearing inner ring 9 to the set position of the main cone 10, and then the piston rod connection seat 2 returns, and the upper fixed pressure head 1 and the upper pressure head 8 rises, the main cone 10 with the lower bearing pressed remains on the tray 12, and the main cone 10 that has been...

[0002] figure 1 and figure 2 Shown is the press-fitting process equipment for the inner ring of the axle main cone bearing in the prior art. The upper pressure head 8 is inserted into the upper fixed pressure head 1 and connected with bolts 11. The upper fixed pressure head 1 is connected with the piston rod connecting seat 2, and the piston rod The rod connection seat 2 pushes the upper fixed pressure head 1 and the upper pressure head 8 to press the lower bearing inner ring 9 to the set position of the main cone 10, and then the piston rod connection seat 2 returns, and the upper fixed pressure head 1 and the upper pressure head 8 rises, the main cone 10 with the lower bearing pressed remains on the tray 12, and the main cone 10 that has been pressed on the inner ring of the lower bearing is manually removed, and after the tray 12 is removed by the conveying line body 13, the removed The opened main cone is placed on the lower pressing head 14 and waits for the next procedure; however, the main cone 10 is heavy overall and relatively large in size, so it is not easy to grasp by hand. Bevel gear surface; on the other hand, manual handling is very labor-intensive, and there is a potential safety hazard of being injured by the main cone
