Embodiment 1

[0018] Steering column bearing assembly tooling of the present invention such as figure 2 , 3 As shown, one end of the base plate 1 is equipped with a cylinder 3 with a horizontally telescopic piston rod through an underframe 2 . The other end of the bottom plate 1 is formed with a horizontal chute 1-1 extending in the telescopic direction of the piston rod, and the assembly support block 4 is installed. The specific structure of the assembly support block is as follows: Figure 4 , 5 As shown, the middle part of the upper surface of the base plate 21 extends upwards to a riser 22 , and a support plate 23 is welded and fixed between the upper surface of the base plate 21 and the surface of the riser 22 away from the cylinder 3 . The top of the riser 22 is provided with a U-shaped groove, and the lower end of the U-shaped groove is formed into a stepped shape by coaxial semicircles with a large diameter and semicircles with a small diameter connected to each other. The rad...

Embodiment 2

[0022] Steering column bearing assembly tooling of the present invention such as Figure 6 As shown, the basic structure is the same as that of the embodiment, the difference is that the piston rod front end looper of the cylinder 3 has a rotatable cylindrical plug 3-1, and the rear end of the cylindrical plug 3-1 passes through the axial retaining ring 3 -2 Axial limit, the outer circle has a four-thread thread 3-3 with a large lead, and the vertical plate 22 of the assembly support block 4 extends out of the pallet 25 toward the direction of the cylinder 3, and the pallet 25 has a U-shaped opening with the opening facing upward. The center of the semi-circle at the bottom of the U-shaped opening is concentric with the large-diameter semi-circle and small-diameter semi-circle of the U-shaped groove and the cylindrical top, and the semi-circular arc at the bottom is formed with a spiral groove that matches the four-thread thread, and the cylindrical top 3- The front end of 1 h...

Abstract

The invention relates to a steering column bearing assembly tool and belongs to the technical field of hydraulic steering gear manufacture. A cylinder provided with a horizontally telescopic piston rod is mounted at one end of a bottom plate of the tool, and the other end of the bottom plate and the bottom of an assembly support block form a positionable moving pair through a horizontal chute; a U-shaped groove is formed in the top of the assembly support block, and the lower end of the U-shaped groove is in a step shape by means of a major-diameter semicircle and a minor-diameter semicircle which are coaxial and jointed; the radius of the minor-diameter semicircle is larger than that of the small end of a steering column, and the minor-diameter semicircle is far away from the cylinder; the radius of the major-diameter semicircle is matched with the radius of the excircle of a steering column bearing, and the center of the major-diameter semicircle is coaxial with the piston rod. During assembly, the bearing is placed on the major-diameter semicircle of the U-shaped groove, the small end of the steering column penetrates the bearing, the position of the assembly support block is regulated along the horizontal chute, the cylinder is started, the steering column is pushed by aid of the piston rod, so the bearing can reach the step end surface between the big end and the small end reliably, high efficiency is realized, and position precision and parallelism can be guaranteed.

Description

technical field [0001] The invention relates to an assembly tool, in particular to a steering column bearing assembly tool, which belongs to the technical field of hydraulic steering gear manufacturing. Background technique [0002] The steering column is the torque transmission device between the steering wheel of the vehicle and the control elements of the vehicle, and its structure is as follows: figure 1 As shown, it includes the small end X connected with the steering wheel and the big end D connected with the vehicle control elements. After assembly, the stepped end face between the small end and the large end is equipped with a bearing Z. During operation, when drivers apply steering force to the steering wheel, the steering column is input to the vehicle control elements to make corresponding steering actions. [0003] In the prior art, the assembly methods of the bearings are all manually knocked with a hammer. In this way, it is difficult to ensure the parallelis...
