The utility model discloses a high-rigidity half-moon groove tool rest unit of a combined lathe and the combined lathe, belongs to the technical field of numerical control combined lathes, and solves the problems that a traditional linear guide rail feeding structure is large in occupied space, poor in rigidity and unstable in machining quality. The tool rest unit comprises a tool rest body, and a guide groove is formed in the circumferential face of the tool rest body and axially penetrates through the tool rest body. A sliding groove plate matched with the guide groove is arranged in the guide groove. The sliding groove plate is shorter than the guide groove and used for bearing a cutter. And the section of the guide groove is half-moon-shaped. Limiting plates are installed on the portions, on the two sides of a groove opening of the guide groove, of the tool rest body respectively, and the limiting plates are pressed on the sliding groove plates so as to limit movement of the sliding groove plates in the radial direction. Due to the fact that the sliding groove and the sliding groove plate are arranged on the peripheral face of the tool rest body, occupied space is reduced, and rigidity and transmission efficiency of the whole structure are improved. The tool rest unit is matched with a narrow space scene of a multi-spindle lathe, and the machining requirements of high precision and high efficiency are met.

The utility model provides a positive and negative surface conductive structure applied to flexible film circuit, include: flexible base material layer, flexible base material layer is PET material quality, circuit layer, set up in the positive and negative two sides of flexible base material layer, conductive connection structure is used for realizing the electric connection of flexible base material layer positive and negative two sides circuit layer, and conductive connection structure includes the through -hole of setting up on flexible base material layer and fills in the through -hole and fills in the through -hole around circuit layer on the hole filling conductive layer. This scheme through setting up the through -hole of specific diameter and quantity on flexible base material layer, and adopt the design of multilayer hole filling conductive layer, realized the double -sided printing of circuit, effectively solved the problem that circuit layout single side cannot layout in prior art, reduced the size area of product, this conductive structure adopts the preparation of printing process, and the process is simple, and the cost is low, is fit for large -scale production.

This utility model discloses an irregularly shaped corner solid square pile and a combined pile. The solid square pile includes a pile body, which comprises alternating square segments and irregularly shaped segments along its length. Each irregularly shaped segment includes a cylindrical portion and a first protrusion extending radially outward from the outer side of the cylindrical portion. The position of the first protrusion corresponds to the position of the diagonal of the cross-section of the square segment. The diameter of the cylindrical portion is less than or equal to the side length of the square segment. The pile body has square segments at both ends. A cylindrical connecting segment is also provided at both ends of the pile body, with the outer diameter of the cylindrical connecting segment being less than or equal to the side length of the square segment. A skirt plate is provided on the outer side of the cylindrical connecting segment, and / or an end plate is provided at the end of the cylindrical connecting segment. The irregularly shaped corner solid square pile disclosed in this application, because it also has cylindrical connecting segments at both ends of the pile body, with the outer diameter of the cylindrical connecting segments being less than or equal to the side length of the square segment, can reduce the perimeter or end area of ​​the precast pile connection portion, thereby reducing the size (area) of the skirt plate or end plate of the irregularly shaped corner solid square pile, further reducing costs.
