Description

Technical Field

[0001] The utility model relates to an assembly tool for a drive axle of a wheeled excavator, in particular to an assembly tool for a half-axle of a drive axle of a wheeled excavator. Background Art

[0002] At present, there is a method for assembling a half-axle of a wheeled excavator drive axle in the market. First, the bearing is placed in the axle housing of the wheeled excavator drive axle, and then the bearing end face is hit with a rubber hammer. When hitting, it is necessary to hit along the symmetrical points on the bearing end face in sequence to press the entire bearing into the axle housing. Since an oil seal is provided on the end face of the bearing facing outward, a position for placing the oil seal is reserved in the axle housing. For this reason, the bearing cannot be pressed to the bearing position in one step. At this time, it is necessary to use a copper rod to hit the bearing to the bearing position, and then install the oil seal in the axle housing at the outer end of the bearing, and finally manually install the half-axle. However, since a spline is provided on the half-axle, it is easy to cause the cutting edge on the spline to scratch the oil seal during installation, thereby causing oil leakage, affecting the environment and service life.

[0005] The slide mechanism consists of a slide, a slider I, a slide rail I, a cushion block, a support block and a bracket. The slide is slidably connected to the slide rail I arranged on the base through the slider I. The cushion block, the support block and the bracket that can support the half-axle are arranged in sequence on the slide along the sliding direction.

[0006] The bracket is composed of a U-shaped block, a slide rail II, a slider II and a support plate. The slider II is arranged on the support plate installed on the lower surface of the slide plate, and the slide rail II is installed in the slider II. The U-shaped block is arranged at one end of the slide rail II close to the positioning mechanism I and the positioning mechanism II.
