The steering column consists of a steering shaft, an upper column tube, a clamping mechanism and a lower column tube.
[0003] The steering column is assembled with the lower column tube, the upper column tube and the steering shaft. Figure 1 As shown, after assembly, the bearing of the lower column tube 1 realizes the anti-dropping function through the rivet point 11 to prevent the bearing from falling out of the lower column tube 1, which is a very important safety function. Affected by the structure and part characteristics, there are strict requirements on the rivet point size and the pull-out force of the lower column tube.
[0004] During the prototype development stage, there are many product types and a tight development cycle. Special equipment is used to rivet the lower column tube of the steering column. This has the disadvantages of long equipment manufacturing cycle, poor multi-product versatility, and high tooling changeover costs.

Two mounting blocks are installed on the outer side of the clamping ring, and the mounting positions of the two mounting blocks correspond to the positions of the rivet points of the lower column tube. An adjusting bolt and a rivet head are arranged in the mounting hole of the mounting block. The end of the adjusting bolt is connected to the tail of the rivet head by a T-block, and the end of the rivet head passes through the through hole on the inner surface of the clamping ring. A fastener is arranged at the bottom of the clamping ring.
[0008] The fastener is a tightening bolt.
[0009] The clamping ring is sleeved outside the riveted end of the lower column tube.
[0010] The height and shape of the rivet head match the model of the lower column tube and the design requirements of the rivet point.
[0011] The installation positions of the installation blocks are located on both sides of the clamping ring.
[0012] The mounting block and the adjusting bolt are connected by threads.
[0013] The end of the adjusting bolt is provided with a T-shaped slot, the tail of the rivet head is provided with a T-shaped block, and the T-shaped block is inserted into the T-shaped slot.
[0014] Compared with the prior art, the utility model designs a riveting tool for the lower column tube of the steering column, which meets the riveting requirements of sample parts with a small number of assemblies, is easy to operate, improves the sample assembly efficiency and quality, and reduces the sample assembly cost. The lower column tubes of steering columns of different models can be riveted by replacing the rivet head and the clamping ring, has strong versatility and low replacement cost.

[0021] The utility model is now further described with reference to the accompanying drawings.
[0022] See also Figure 2 , Figure 3 The utility model is a riveting tool for a lower column tube of a steering column, comprising a clamping ring, a mounting block, an adjusting bolt, a rivet head, and a fastener. Two mounting blocks 24 are mounted on the outer side of a clamping ring 21. The mounting positions of the two mounting blocks 24 correspond to the positions of the rivet points 11 of the lower column tube 1. An adjusting bolt 23 and a rivet head 22 are arranged in the mounting hole of the mounting block 24. The end of the adjusting bolt 23 is connected to the tail of the rivet head 22 by a T-block. The end of the rivet head 22 passes through a through hole 211 on the inner surface of the clamping ring 21. A fastener 25 is arranged at the bottom of the clamping ring 21.
[0023] For ease of use, the fastener 25 is a tightening bolt. The mounting block 24 and the adjusting bolt 23 are connected by threads.
[0024] The height and shape of the rivet head 22 match the model of the lower column tube 1 and the design requirements of the rivet point 11 to meet the different riveting requirements of steering columns of different models.
[0025] The mounting positions of the mounting blocks 24 are located on both sides of the clamping ring 21 .
[0026] See also Figure 4 In order to facilitate the installation and removal of the adjusting bolt 23 and the rivet head 22, a T-shaped slot is provided at the end of the adjusting bolt 23, and a T-shaped block is provided at the tail of the rivet head 22, and the T-shaped block is inserted into the T-shaped slot. When a different rivet head 22 needs to be replaced, the T-shaped block of the original rivet head 22 is slid out of the T-shaped slot of the adjusting bolt 23, and then the T-shaped block of the replaced rivet head 22 is inserted into the T-shaped slot of the adjusting bolt 23.
[0027] See also Figure 5 , Figure 6 When the utility model is working, a rivet head 22 and a matching clamping ring 21 of a customized design standard are selected according to the model of the steering column. The rivet head 22 is installed to the end of the adjusting bolt 23. Then, the clamping ring 21 is sleeved outside the riveted end of the lower column tube 1. After aligning the rivet head 22 with the rivet point 11 of the lower column tube 1, the tightening bolt is locked to fix the clamping ring 21 to the lower column tube 1. Manually tighten the adjusting bolt 23, and the adjusting bolt 23 pushes the rivet head to apply force to the rivet point 11 of the lower column tube 1. The screwing position of the adjusting bolt 23 is limited by the height of the rivet head 22. The adjusting bolt can be adjusted to a customized position according to the design standard requirements. After the adjusting bolt 23 screws the tail of the rivet head 22 into the customized position, the size of the end of the rivet head 22 compresses the rivet point 11 and deforms to meet the design requirements of the drawing. After the riveting is completed, the adjusting bolt 23 is unscrewed, the rivet head 22 is pulled out from the riveting point 11 , the tightening bolt is loosened, and the lower column tube 1 is taken out from the clamping ring 21 .
