The utility model discloses a vertical machining center drilling positioning tool which comprises a bottom plate, a positioning shaft sleeve seat is arranged on the bottom plate through a positioning mandrel, a positioning shaft sleeve is arranged on the positioning shaft sleeve seat, and a pressing plate and a tool nut are sequentially arranged on the positioning shaft sleeve. A workpiece needing to be drilled is installed between the positioning shaft sleeve and the positioning shaft sleeve seat, and the workpiece needing to be drilled is connected with the bottom plate through assembly of the positioning pin and the positioning sleeve. On the premise of ensuring the hole site precision of the workpiece, the operation is simplified, the production efficiency is improved, common use of the same kind of workpieces (parts) of different specifications can be achieved by replacing positioning shaft sleeves of different specifications, meanwhile, the first machining face serves as the positioning reference when the workpiece is turned over and machined, the accuracy of a finished product is improved, and the universality of the positioning tool is improved; the cost is further reduced.

The utility model discloses an adjustable handrail. The adjustable handrail comprises a middle rod which is hollow in the axial direction; the two connectors are detachably installed at the two ends of the middle rod respectively, one connector is inserted into the middle rod, and the installation depth of the connector can be adjusted in the axial direction of the middle rod. The locking piece is located in the middle rod and installed on the end portion of the connector with the installation depth capable of being adjusted. The locking piece is sleeved with the locking sleeve, and in the process that the locking piece is installed on the corresponding connector, the locking piece has acting force for driving the locking sleeve to expand on the locking sleeve, so that the locking sleeve abuts against the inner wall of the middle rod; through cooperation of the connector and the middle rod, the adjustable handrail can adjust the overall installation length, and the adjustable handrail is suitable for various products and high in universality and universality. The locking piece and the locking sleeve are hidden in the middle rod to fix the connector, the external space of the middle rod is not occupied, and the problems of interference with a product and the like can be avoided when the locking piece and the locking sleeve are matched with the product for installation and use.

The application discloses a diameter 1200-1700mm large-diameter seamless steel pipe sizing production method, and belongs to the technical field of seamless steel pipe manufacturing in the metallurgical industry. The application adopts large continuous casting billet piercing, cross rolling expanding, directly heating furnace reheating after equalizing cross rolling, on-line reheating, and then sizing, so that the production heating frequency of the steel pipe is reduced, the finished product inner and outer grinding and polishing are realized, the material yield is high, one roughing mill and one set of rolls can be used for sizing the large-diameter steel pipe, the outer diameter group distance of the sized pipe is large, that is, the roll commonality is strong, and the mold investment amount is reduced. The application utilizes the reciprocating rolling of the roughing mill and the movement and overturning of the push-pull bed, can balance the deformation of each surface, and the group distance of the two rolls for sizing the pipe is relatively large. Compared with the existing traditional steel pipe sizing and outer diameter control production process, the production frequency of the application is less, the production process is simple, the production efficiency is high, the mold investment amount is small, and the production cost is greatly reduced.

The invention provides a cross-modal fine-grained retrieval method based on modal specific features and modal sharing features. The target of the cross-modal fine-grained retrieval task is that a user gives any sample as a query sample, and the system retrieves to obtain each modal sample related to the query sample. On one hand, a branch network is used for extracting modal specific features of each modal, so that feature information of each modal is fully utilized; and on the other hand, the same network is used for extracting common features of the modes so as to enhance the relation between the modes, and the model learns the generality and the relation between data of different modes. In this way, specific information of each mode and shared information of different modes are utilized at the same time, semantic information contained in the high-dimensional semantic space vector is increased, heterogeneous gaps and semantic gaps between samples are reduced, the clustering capacity of the model for the high-dimensional space vector is enhanced, and the cross-modal retrieval capacity of the model is further improved.
