Description

Technical Field

[0001] This utility model belongs to the technical field of automotive parts processing equipment, specifically, it relates to a frame riveting device. Background Technology

[0002] In the manufacturing process of automotive steering wheels, the assembly of the frame is a crucial step. The frame is typically composed of multiple components connected together by riveting to ensure the overall structural strength and stability of the steering wheel. Currently, existing frame riveting devices have some shortcomings.

[0003] Utility model CN216881573U discloses a riveting and positioning fixture for a steering wheel frame, comprising a base, a support block, and a positioning mechanism. The base is provided with guide rails and a mounting seat. At least four guide rails are radially and evenly arranged around the mounting seat, with threaded holes on at least one side of each guide rail. The support block is slidably mounted on the guide rails, and its bottom has a protrusion with an elongated adjusting groove matching the threaded hole. The positioning mechanism is detachably mounted on the mounting seat and includes a connecting seat, a positioning shaft, a positioning post, and a support post. The positioning shaft, positioning post, and support post are all fixed to the upper side of the connecting seat. By providing a detachable and replaceable positioning mechanism and a movable support block, the fixture can adapt to the riveting and positioning of steering wheel frames of different models and sizes, improving its practicality, reducing production costs, and saving workshop space.

[0004] However, the above-mentioned patent still has the following problems: the height adjustment effect of the clamping structure is not good, and its height cannot be flexibly adjusted according to the specific needs of different sized steering wheel frames. When encountering some special shapes or sizes of steering wheel frames, the clamping structure may not fit perfectly with the frame, resulting in unstable clamping. During the riveting process, the frame is prone to shaking or displacement, and the steering wheel position is easily shifted during clamping. The limiting effect is not good, and the device is inconvenient to use.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0040] Working principle: The steering wheel frame 38 is placed between two sets of arc-shaped clamping plates 36. Rotating the knob rod 29 drives the first threaded rod 30 to rotate, causing the first threaded sleeve 33 to rotate inside the first movable plate 32. At the same time, the guide rod 31 and the limiting hole 34 guide the first movable plate 32, thereby changing the distance between the two sets of arc-shaped clamping plates 36, thus achieving the limiting and fixing of the steering wheel frame 38. The air cushion plate 37 can increase friction and provide buffer protection. The bottom of the first connecting flange 15 is connected to the top of the second connecting flange 17. The limiting bolt 20 is screwed into the first threaded groove 16 and the second threaded groove 18 to achieve the connection and fixing of the first connecting flange 15 and the second connecting flange 17. Then, the riveting die plate 19 is connected to the hydraulic push rod 14. The hydraulic cylinder 13 is powered and controlled by the power supply box 12. Activating the hydraulic cylinder 13 drives the hydraulic push rod 14 to move, causing the riveting die plate 19 to move downwards, thus riveting the fixed steering wheel frame 38. The hexagonal nut 21 enhances the limiting effect of the limiting bolt 20. The steering wheel frame 38 is placed on top of the fixed base plate 10, supported by the first anti-slip pad 22 and the second anti-slip pad 23 to prevent slippage. The bottom of the steering wheel frame 38 is in close contact with the top of the anti-wear plate 25. The riveting position of the steering wheel frame 38 is positioned by the first positioning plate 24 and the anti-wear plate 25 to ensure accurate riveting.
