Description

Technical Field

[0001] This invention relates to the field of automotive parts processing, and in particular to a welding and adjustment fixture and process for a rear axle flange plate. Background Technology

[0002] In existing technologies, the rear axle welded assembly is a crucial structural component of the automotive chassis, used to support springs, shock absorbers, rear wheel brake modules, and pipeline harnesses, and to transmit suspension loads; it is a non-independent suspension. As a non-independent suspension, the flange face of the rear axle welded assembly needs to provide high-precision four-wheel alignment parameters such as toe-in and camber angles to meet the four-wheel alignment requirements after vehicle assembly and to satisfy the overall vehicle handling design needs.

[0003] Figure 1 This is a structural schematic diagram of the rear axle welded assembly. Figure 1 As shown, the rear axle welded assembly is welded from a crossbeam 10, a suspension arm 11, a body sleeve 12, a spring disc 13, a shock absorber bracket 14, a flange plate 15, and a reinforcing plate.

Figure 3 This is a schematic diagram of a traditional flange adjustment mechanism. Figure 2 and Figure 3 As shown, in the conventional rear axle welding assembly assembly OP10 process tooling 20, a flange plate positioning and adjustment mechanism 21 is arranged on the outer side of the flange plates on both sides. The flange plate positioning and adjustment mechanism 21 consists of a flange plate positioning block 22, a slide rail 23, a base 24, and a clamping mechanism 25. Four positioning points 27 are arranged on the flange plate positioning surface 26 of the flange plate positioning block 22.

[0080] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0081] Embodiments of the invention will now be described in detail with reference to the accompanying drawings. Preferred embodiments of the invention will now be described in detail, examples of which are shown in the drawings. Wherever possible, the same reference numerals will be used in all the drawings to denote the same or similar parts.

[0082] Furthermore, although the terminology used in this invention is selected from commonly known and used terms, some terms mentioned in this specification may have been selected by the applicant in his or her judgment, and their detailed meanings are explained in the relevant sections of the description herein.

[0083] Furthermore, the invention should be understood not only through the actual terminology used, but also through the meaning implied by each term.

[0084] like Figure 4 and Figure 5As shown, this invention discloses a rear axle flange welding and adjustment fixture, comprising: a base plate 100, a toe angle base plate 200, a camber angle base plate 300, a camber angle adjustment assembly 400, a toe angle adjustment digital display 500, and a camber angle adjustment digital display 600. The toe angle base plate 200 is rotatably connected to the base plate 100. For example, the toe angle base plate 200 is rotatably connected to the base plate 100 via a toe angle rotation shaft 700. One end of the camber angle base plate 300 is rotatably connected to one end of the toe angle base plate 200. For example, the camber angle base plate 300 and the toe angle base plate 200 are rotatably connected via a camber angle rotation center shaft 800.

[0085] A camber adjustment assembly 400 is mounted on the base plate 100, located between the other end of the camber base plate 300 and the other end of the toe angle base plate 200. Adjusting the camber adjustment assembly 400 allows the camber base plate 300 to be adjusted vertically. A toe angle adjustment digital display 500 is mounted on the side of the toe angle base plate 200 to read the angle adjustment value. A camber adjustment digital display 600 is mounted on the other end of the camber base plate 300 to read the angle adjustment value.

[0086] Preferably, a plurality of toe angle locking bolts 210 are provided on the toe angle base plate 200 for locking the toe angle base plate 200. A plurality of toe angle adjusting bolts 220 are installed on the base plate 100, located on both sides of the toe angle base plate 200, for adjusting the rotation angle of the toe angle base plate 200.

[0087] Similarly, preferably, a plurality of outward tilt angle locking bolts 310 are installed on the outward tilt angle base plate 300 for locking the outward tilt angle base plate 300.

[0088] The camber adjustment assembly 400 includes a camber adjustment threaded rod 410, a camber adjustment threaded sleeve 420, and a camber adjustment cap 430. The camber adjustment threaded sleeve 420 is mounted on the base plate 100. One end of the camber adjustment threaded rod 410 passes through the camber adjustment threaded sleeve 420 and abuts against the toe angle base plate 300, with the upper part of the camber adjustment threaded rod 410 contacting the bottom of the camber base plate 300. The camber adjustment cap 430 is connected to the other end of the camber adjustment threaded rod 410 and is used to adjust the movement of the camber adjustment threaded rod 410.

[0089] Furthermore, the camber adjustment assembly 400 also includes a camber adjustment pad 440, and the bottom of the other end of the camber base plate 300 is configured as a ramp surface 320, on which the camber adjustment pad 440 is mounted.

[0090] Furthermore, the camber adjustment assembly 400 also includes a camber adjustment support block 450. A stepped surface 230 is formed on the upper surface of the other end of the toe angle base plate 200, and the camber adjustment support block 450 is mounted on the stepped surface 230. One end of the camber adjustment threaded rod 410 abuts against the camber adjustment support block 450 and the toe angle base plate 200 in sequence, and the upper end of the camber adjustment support block 450 is in contact with the camber adjustment pad block 440.

[0091] This invention also provides a process method for welding and adjusting a rear axle flange plate using the aforementioned rear axle flange plate welding and adjusting fixture. The process method includes:

[0092] like Figure 6 As shown, when adjusting the positive angle of the toe angle base plate 200, first loosen the toe angle locking bolt 210; adjust the toe angle adjusting bolt 220, and the toe angle base plate 200 rotates around the toe angle rotation axis 700. When the rotation angle is in place, tighten the toe angle locking bolt 210, and the toe angle base plate 200 completes the angle adjustment.

[0093] like Figure 7 As shown, when adjusting the toe angle base plate 200, first loosen the toe angle locking bolt 210; adjust the toe angle adjusting bolt 220, and the toe angle base plate 200 rotates around the toe angle rotation axis 700. When the rotation angle is in place, tighten the toe angle locking bolt 210, and the toe angle base plate 200 completes the angle adjustment.

[0094] like Figure 8 and Figure 9 As shown, the process further includes: when adjusting the positive angle of the tilt angle substrate 300, first loosen the tilt angle locking bolt 310; adjust the tilt angle adjusting screw cap 430, and the tilt angle substrate 300 rotates around the tilt angle rotation center axis 800; when the rotation angle is in place, tighten the tilt angle locking bolt 310, and the tilt angle substrate 300 completes the angle adjustment.

[0095] like Figure 10 and Figure 11 As shown, when adjusting the opposite angle of the tilt angle base plate 300, first loosen the tilt angle locking bolt 310; adjust the tilt angle adjusting screw cap 430, and the tilt angle base plate 300 rotates around the tilt angle rotation center axis 800; when the rotation angle is in place, tighten the tilt angle locking bolt 310, and the tilt angle base plate 300 completes the angle adjustment.

[0096] like Figure 12 and Figure 13As shown, on the rear axle welding assembly fixture, one side of the flange plate connecting block 30 is bolted to the rear axle flange plate welding adjustment fixture 40, while the other side is tightly fitted to the rear axle flange plate. The welding sequence is achieved by adjusting the rear axle flange plate welding adjustment fixture 40 to ensure that the flange plate connecting block 30 and the flange plate mating surface achieve the required spatial angles for the rear axle toe-in and camber angles, thus achieving precise positioning of the flange plate.

[0097] More specifically, the adjustments are as follows:

[0098] The rear axle flange welding adjustment fixture 40 has toe angle adjustment bolts 220 on its left and right sides near the outside. Loosen the toe angle adjustment bolts 220 and adjust them in the desired direction. The mechanism will rotate around the component's toe angle rotation axis 700. Depending on the required angle, the adjustment can be achieved by rotating to the scale position. The specific adjustment value can be read from the toe angle adjustment digital display 500.

[0099] An outward tilt adjustment screw cap 430 is arranged in the middle of the outer side of the adjustment mechanism. When the outward tilt adjustment screw cap 430 is rotated, it will push the inner outward tilt adjustment threaded rod 410. As the outward tilt adjustment threaded rod 410 is pushed inward, the outward tilt adjustment support block 450 will press against the outward tilt adjustment pad block 440, thereby causing the outward tilt base plate 300 to rotate and rise or fall along the component's outward tilt rotation center axis 800, thus realizing the outward tilt adjustment. The specific adjustment value can be read from the outward tilt adjustment digital display 600.

[0100] After the above angles are adjusted, the positioning position of the flange plate adjustment mechanism can be locked by tightening the toe angle locking bolt 210 and the camber angle locking bolt 310, thereby achieving the positioning of the flange plate on the rear axle assembly tooling.

[0101] The rear axle flange plate welding adjustment fixture of this invention mainly solves the problem of operation convenience when adjusting the toe angle and camber angle of the flange plate on the welding site, and improves the dimensional adjustment accuracy of the welding assembly. This mechanism has good applicability in the rear axle torsion beam assembly fixture.

[0102] Using the existing welding fixtures, along with precision-stamped flange plates and machining of the flange plate mounting holes in the disassembled state, can be used for some models with general four-wheel alignment accuracy levels. This eliminates the need for machining after rear axle welding, thereby simplifying the process, eliminating investment in assembly machining equipment, and reducing parts processing costs.

[0103] The fixture mechanism for welding flanges on subsequent torsion beam welding fixtures can be widely applied to improve the positioning accuracy of flanges. For parts of some assemblies with low requirements for four-wheel positioning accuracy, the post-weld machining process of the rear axle welding assembly can be eliminated by adjusting the process of the flange assembly, thereby reducing equipment investment and manufacturing costs.

[0104] In summary, the welding adjustment fixture and process method for the rear axle flange plate of the present invention improves the convenience of operation when adjusting the toe angle and camber angle of the flange plate on the welding site, and improves the dimensional adjustment accuracy of the welding assembly. It has good applicability in the assembly fixture of the rear axle torsion beam.

[0105] The rear axle flange plate welding and adjustment fixture uses a precision-stamped flange plate and completes the machining of the flange plate mounting holes in a disassembled state. This is suitable for some vehicle models with general four-wheel alignment accuracy levels. It eliminates the need for post-weld machining of the rear axle, thereby simplifying the process, eliminating investment in assembly machining equipment, and reducing parts processing costs.
