The utility model relates to mechanical processing auxiliary equipment field especially, and is split type bearing shell drilling positioning frock, including split type bearing shell drilling positioning frock, including base, clamping component, and clamping mechanism includes T type clamp plate, and T type clamp plate includes connecting plate and clamp plate, and the clamp plate is located split type bearing shell mounting hole, and the bottom fixed position column of connecting plate tail end, and the base is fixed with hollow tube, and the inner chamber diameter of hollow tube is greater than the outer diameter of position column, and the hollow tube position column rotation connects, and the vertical installation adjusting screw rod on base, and the central hole is set up in connecting plate, and adjusting screw rod passes through the hole and penetrates T type clamp plate, and the adjusting screw rod is screwed adjusting nut, and adjusting nut is located T type clamp plate top. Through the matching of arc locating groove and split type bearing shell connecting lug outer arc surface, avoid the vibration when punching and cause bearing shell to shake, improve drilling processing accuracy. Compression spring can play the role of saving strength when replacing bearing shell, and the labor intensity of operating personnel is reduced.

This utility model relates to the field of transfer box technology and discloses a hollow board turnover box, comprising: a box body, which is composed of multiple hollow boards spliced ​​together, and the hollow boards have honeycomb-shaped hollow cavities inside; reinforcing columns are provided at the four corners of the box body, and the reinforcing columns are fixedly connected to the hollow boards, and the reinforcing columns also have hollow cavities inside; a groove is formed on the top of the box body; a protrusion is installed on the bottom of the box body, and the shape of the groove matches the shape of the protrusion; multiple ventilation holes are evenly formed on the side walls of the box body; and a moisture-proof net is installed in the ventilation holes. In this utility model, by setting the box body, groove, and protrusion, the honeycomb-shaped hollow cavities inside the box body ensure lightweight and high-strength support, while the embedded structure of the protrusion and groove and the design of the rubber anti-slip pad prevent lateral sliding or tipping during stacking, thereby improving the utilization rate of storage space and ensuring the stability of logistics transportation.

This utility model relates to the field of steel structure technology, specifically to a welding steel structure clamp, comprising a base, with clamps on both sides of the upper middle portion of the base, each clamp including a base plate, with a fixed clamping plate fixedly installed on one side of the upper part of each base plate, and a sliding groove formed in the middle of the upper part of each base plate, the sliding clamping plate being slidably engaged in the middle of the sliding groove, a hollow groove formed in the middle of one end of the base, a semi-circular worm gear fixedly installed on one side of the middle of the hollow groove, a semi-circular sliding groove formed in one side of the middle of one end of the base, a semi-circular sliding plate being slidably engaged in the middle of the semi-circular sliding groove, a fixed plate fixedly installed at the lower end of the semi-circular sliding plate, and a worm gear rotatably installed in the middle of one end of the fixed plate. This utility model solves the problem that traditional clamps are mostly fixed angles, such as right angles, and can only meet the needs of straight line or simple angle welding, such as flat welding and fillet welding, which have many shortcomings in practical use.
