Yue Luo Customized 304 Stainless Steel Inner Hexagonal Oil Plug Plug, Inner Hexagonal Thread Plug, Pipe Plug, and Screw Plug

Pin the steering seat on the car ball head and assemble the roller onto the steering seat through the pin. The existing technologies are all manual pin driving, which results in inaccurate pin position, high labor intensity, low efficiency, and also affects the quality of the steering seat. Therefore, it is necessary to design an automatic pin driving mechanism to drive the pin into the steering seat.

Screws are commonly used fastening parts in machinery, but most of the commonly used screws in the market are standard products. The standard screws themselves are ordinary, without anti loosening and protecting the substrate. Therefore, in order to prevent screws from loosening in use, elastic washers, flat washers and other elastic washers and flat washers that are usually suitable for screws are metal products, which are easy to wear with the body substrate and damage the protective layer of the sheet metal substrate in use. Long term use can easily rust metal washers, affecting the fastening effect and aesthetics of the screws. In addition, using metal washers not only increases weight and cost, but also complicates the assembly process and has poor anti loosening effect.

In existing technology, there are two implementation methods for screw suction devices: one is to use a magnet to magnetize the electric screwdriver head, and use the electric screwdriver head to approach the screw. The screw is then stuck by the electric screwdriver head, which can achieve the function of picking up the screw; One method is to use a vacuum generator to create negative pressure in the screw guide groove, suck the screw into the tube, and achieve screw pickup. The disadvantage of this solution is that during the process of picking up the screw, it is not possible to fully align with the screw groove, resulting in deviation or leakage of the screw. The disadvantages of the two schemes are that the screws with the Aspect ratio less than 1.8 are prone to be misaligned, and the stability is not high. It can be seen that the existing technology still needs improvement and development.

The front soundproofing and insulation pad is used to absorb the heat and noise transmitted by the firewall, while also playing a role in insulation and vibration isolation, ensuring a relatively quiet and comfortable environment inside the car, and improving ride comfort. As shown in Figures 1 and 2, the fixation of the front wall sound insulation pad 101 with the vehicle body is generally achieved through the screw buckle 102. The screw 100 is clamped by the clamp 103 in the screw buckle 102, and the limit bar 104 in the screw buckle 102 clamps the screw 100. After the screw 100 is inserted into the screw buckle 102, the tail end of the screw 100 is exposed, which can easily scratch the operator when assembling other components. Moreover, the exposed screw 100 is also prone to rust, affecting the connection strength of the screw 100 and reducing the service life of the screw 109.

Among them, pneumatic rivet pulling machines are more commonly used, and they are also equipped with a fixture for assembling rivets. Existing fixtures usually use two rotating clips for buckle assembly, but rotation can easily cause the two clips to buckle out of place, thereby affecting the assembly of rivets.
