Dowels are made on the steering seat on the ball head of the car, and the rollers are assembled to the steering seat through the dowels. The prior art is manual driving of the pins, and the position of the pins is inaccurate when driving the pins, the labor intensity is high, the efficiency is low, and the quality of the steering seat is also affected. Therefore, it is necessary to design an automatic pin-driving mechanism to drive the pins into the steering seat. .
One of the steps in the screw production and processing process is to slot the screw head to facilitate the use of a screwdriver when tightening or loosening the screw. Generally, companies use manual sorting, and then use the cutting knife to slot the front end screws through the track, which is inefficient, and because the screws are not fixed, the cutting knife may easily fly out or break the blade during cutting. It is a safety problem, and after cutting, the screw head has rough workmanship and burrs, which is easy to hurt the hand.
The shear strength of a metal material refers to the ability of the material to withstand shearing force, which refers to the strength of the external force perpendicular to the material axis and shearing the material. The test is usually to install the cylindrical pin into the specified fixture, and the gap between the supporting part and the loading part is required to be no more than 0.15mm, and then force is applied to test the shear strength of the material.
