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.

This utility model discloses a guiding device for multi-nozzle oil painting printing, relating to the technical field of guiding devices. It includes a correction guiding mechanism, with a compensation mechanism and a limiting mechanism arranged on its inner side. By coordinating the compensation and limiting mechanisms, this utility model ensures that during the correction process, the compensation mechanism, through the linkage of the limiting collar and the compensation connecting plate, allows the correction roller to maintain contact with the printing fabric even when tilted, enhancing the friction between the correction roller and the printing fabric and preventing secondary deviation due to insufficient friction, thus improving the stability of the canvas transport. Through the design of the lifting block and auxiliary roller in the limiting mechanism, the height of the auxiliary roller can be automatically adjusted via a pull rope mechanism during the correction process, ensuring it remains in contact with the printing fabric at all times, achieving secondary correction and guiding functions, further enhancing the trajectory control capability of the canvas during the correction process.

The application relates to the technical field of semiconductor manufacturing, in particular to a wafer transfer box and a semiconductor device. The wafer transfer box is used for avoiding the problems of easy contamination and easy damage in wafer overturning. The wafer transfer box comprises a box body assembly, the box body assembly has a containing space for placing a wafer, and a fixing assembly connected with the box body assembly, the fixing assembly is used for fixing the relative position of the wafer in the containing space at least when the box body assembly is overturned. The wafer is overturned by adopting the mode of overturning the wafer transfer box as a whole, under the premise of avoiding the contamination of the wafer, the fixing assembly is arranged in the wafer transfer box, so that the position of the wafer is fixed relative to the containing space in the process of overturning the wafer transfer box as a whole, the uncertain movement of the wafer in the wafer transfer box is avoided, and then the damage of the wafer in the overturning process can be avoided.

The utility model discloses an umbrella honeycomb structure to solve the problem that an existing umbrella honeycomb structure is inconvenient to open and close or poor in overall stability. The device comprises an upper honeycomb, an outer sleeve, an inner sleeve, a check ring and a spring, the upper honeycomb is installed at the top end of a middle rod of the umbrella, and the outer sleeve is arranged outside the inner sleeve in a sleeving mode and moves in the axial direction of the middle rod along with the inner sleeve; according to the honeycomb structure, the outer sleeve and the upper honeycomb can rapidly achieve the locking function through the clamping hole and the first guide inclined plane which are arranged on the first pull strip and the clamping block and the second guide inclined plane which are arranged on the upper honeycomb, meanwhile, the direction does not need to be distinguished during use, an umbrella can be easily opened and closed, and use is convenient and fast; according to the structural design of the middle rod, the outer diameters of the inner pipe, the middle pipe and the outer pipe are sequentially increased, and the overall supporting performance and stability of the umbrella are improved; the structural stability of the umbrella is enhanced through the check ring, the umbrella can be prevented from swinging in the using process, and the using safety and reliability of the umbrella are improved.
