This utility model provides a pneumatic lifting device for electronic trays, including a tray positioning assembly, a drive assembly, and a handling robot. The tray positioning assembly inserts a central positioning cone into the center hole of the tray, and, in conjunction with a pressure plate, clamps the tray to achieve precise vertical positioning. The drive assembly uses a downward-pressing cylinder to drive the limit plate to rise and fall, with linear bearings ensuring stability. The handling robot uses a rotary cylinder, a gripper cylinder, and a synchronous belt mechanism to achieve 45-degree rotation and extend / retract the fork, completing the tray gripping and handling. This device has a compact structure, high positioning accuracy, and strong adaptability, significantly improving the efficiency and stability of automated production, and is suitable for various electronic trays.

The utility model relates to the technical field of electric power detection, in particular to a magnetic type tower climbing robot device which comprises a driving unit, a protective shell is arranged on the driving unit, a gear cleaning unit is arranged on the protective shell, a guide unit is further arranged in the protective shell, and the driving unit comprises a second fixing frame arranged in the protective shell. A second motor is arranged in the second fixing frame, second magnetic attraction wheels are symmetrically and rotationally installed in the second fixing frame, the second motor drives the second magnetic attraction wheels to rotate through a gear set, the guide unit comprises a first fixing frame arranged in the protective shell, a first motor is arranged in the first fixing frame, and a second motor is arranged in the second fixing frame. According to the magnetic type tower climbing robot device, the conical plate and the spring rod of the gear clearing unit are designed, dirt on the surface of a tower can be effectively cleared away, the dirt is prevented from affecting the adsorption effect of the magnetic wheels, and it is ensured that the robot can stably climb in the complex environment.

The invention relates to the technical field of printing detection, and discloses a printing machine printing multi-stage quality detection device which comprises a detection box, and the top of the detection box is fixedly connected with a collection box. The moving part comprises a supporting column fixedly connected with the bottom of the inner wall of the detection box, a moving hole is formed in the top of the supporting column, a top column is slidably connected to the surface of the inner wall of the moving hole, an air pressure hole is formed in the top of the supporting column, a sliding groove is formed in the bottom of the inner wall of the detection box, and a clamping part is arranged on the surface of the sliding groove. By arranging the moving part, after the power device of the detection box is started, the top column moves upwards from the interior of the moving hole, the top of the top column makes contact with the bottom of the printing paper to lift up the printing paper, the printing paper is moved upwards through the top column, and finally the surface of the printing paper slides relative to the clamping plate, so that the abrasion resistance of the printing paper is detected, and the quality problem of each piece of printing paper is distinguished.

The utility model discloses straightening equipment for metal tubes, which belongs to the technical field of metal tube straightening and comprises a worktable, a support frame is connected below the worktable, side plates are connected to two sides below the worktable, supporting plates are connected to two sides above the worktable, and a plurality of fixing tables are mounted above the worktable through bolts. According to the metal pipe straightening equipment, a worker starts a working motor to rotate a threaded rod, a movable plate is promoted to move along the threaded rod through thread fit of a threaded sleeve and the threaded rod, and therefore a connecting frame is promoted to drive a fixed plate to move horizontally along a guide groove, and the movable fixed plate can push a connecting rod through an inclined groove; the connecting rod is driven to drive the movable table to enable the sliding sleeve to slide on the guide rod, so that the distance between the fixed table and the movable table is adjusted, the distance between the two straightening rollers is changed to adapt to metal pipes with different diameters, operation is easy, manual operation is not needed, and the adjusting and straightening efficiency is improved.

The application discloses a valve body structure and a valve assembly for a gas meter built-in valve, and belongs to the technical field of valves. The valve assembly comprises a valve body structure, the valve body structure comprises a valve body, a valve core and a lip seal ring, the valve core is supported in the valve body through a support frame, the support frame is slidingly matched in a sliding groove, the lip seal ring comprises a ring main body and a lip arranged on the inner side of the ring main body, the position on the lip seal ring for matching the valve core is located on the lip, the end of the support frame is towards the inner end face of the ring main body, and the relative position of the support frame and the lip seal ring satisfies that in the process that the valve core moves towards the lip seal ring, the support frame can move to the state that the end of the support frame is supported on the inner end face. The scheme can effectively optimize the influence of the medium pressure rise on the valve rotation resistance, so that the purposes of optimizing the valve action power consumption and response speed, prolonging the service life of the built-in battery of the gas meter and reducing the maintenance frequency of the gas meter are achieved.

The application discloses a containing and feeding mechanism for motor gear production, which comprises a mounting base, a conveying frame arranged on the mounting base, a conveying groove formed in the mounting base and a feeding frame clamped in the conveying groove, a rectangular groove for connecting a clamping plate arranged on the mounting base, a lifting transmission feeding frame arranged on the top of the clamping plate, a plurality of telescopic inserting rods arranged at the top end of the transmission feeding frame, a butt joint calibration frame arranged on the top of the telescopic inserting rods, a plurality of positioning clamping blocks arranged in the transmission feeding frame, a plurality of transmission shafts arranged on the positioning clamping blocks and a positioning plate arranged on one side of the transmission shafts. Compared with the prior art, the automatic feeding, flatness detection and gap cleaning functions of bevel gears are highly integrated in a compact unit through the mechanism, which not only simplifies the production line layout and reduces the transfer time and cost of materials between different stations, but also is beneficial to realize centralized control and intelligent management of the production process and optimize the whole production process.
