The utility model relates to the technical field of railway vehicle manufacturing and maintenance equipment, in particular to bogie frame turnover equipment with a positioning function, which comprises a support frame, a height adjusting device, a position adjusting device, a clamping device, a turnover device, a positioning device and a control system. Fixing bases are installed in the supporting frame through the two height adjusting devices and the position adjusting device, rotating discs are installed on the two fixing bases through the overturning devices, the clamping devices are installed on the side walls of the rotating discs, the position of a framework is preliminarily detected through a visual recognition system, namely a camera, and the clamping devices are installed on the side walls of the rotating discs. The control system adjusts the distance between the two sets of laser range finders according to deviation information, the position of the framework is further accurately positioned, light beams emitted by the laser range finders are used for auxiliary calibration, it is ensured that the deviation of the framework in the horizontal direction and the vertical direction is controlled within + / -1 mm, and in the overturning process, the positioning device continuously monitors the position of the framework, and the positioning accuracy is improved. And the stability is always kept.

The application discloses a dynamic shaft self-locking nut, which comprises a screwing part and a locking part connected with each other, and a bevel cut is formed between the screwing part and the locking part; when the dynamic shaft self-locking nut is screwed and fastened with a bolt, the locking part is in interference fit with the bolt in a closing direction of the bevel cut to realize self-locking. Compared with a traditional self-locking nut, the dynamic shaft self-locking nut does not need to be provided with an elastic member, and the self-locking effect can be effectively improved. The application further discloses a processing method of the dynamic shaft self-locking nut, which comprises the following steps: S100, selecting a nut blank with a proper length and completing basic processing; S200, calculating an interference amount e of the dynamic shaft self-locking nut and the bolt; S300, according to the interference amount e and proper bevel cut quantity, the depth and the included angle of the required bevel cut are obtained; and S400, cutting the nut blank to obtain the required dynamic shaft self-locking nut. Through the above method, the processing of the nut blank can be simply and accurately realized, and the dynamic shaft self-locking nut meeting the requirements can be obtained.

This utility model relates to the field of gear processing technology, and in particular to a cold forging forming device for locking differential connecting gears. The technical solution includes: a gear-cutting head movably mounted on a base, with a cutting head mounted at its output end; an indexing plate movably mounted below the gear-cutting head on the base; a Y-axis moving module mounted on the base, connected to an X-axis moving frame via a Y-axis moving frame and an X-axis moving module; a Z-axis moving module and a limiting module mounted on the X-axis moving frame; the gear-cutting head mounted on the Z-axis moving module via the Z-axis moving frame; a sliding groove and a first locking tooth on the X-axis moving frame, through which the limiting module is positioned; and a baffle on the Z-axis moving frame cooperating with the limiting module to restrict the movement distance of the gear-cutting head. This utility model, through the cooperation of a spring rod and the locking tooth, can quickly adjust the limiting position according to gears of different thicknesses, making the gear-cutting head suitable for processing gears of different specifications, thus possessing greater versatility and flexibility.
