The invention belongs to the technical field of fluid braking equipment, and particularly relates to a safety limiting device for a pull rope oil cylinder, which comprises a fixed frame, a sliding base and a hydraulic oil cylinder, the device further comprises a stable transmission mechanism. On one hand, in the stretching and retracting process of the hydraulic oil cylinder, the sliding base is driven to move in the mode that the fixed pulley pushes the transmission steel cable, and in the moving process, due to the fact that the fixed pulley and the transmission steel cable are symmetrically distributed on the upper side and the lower side of the hydraulic oil cylinder, tension of the transmission steel cable on a connecting piece is more balanced; on the other hand, due to the arrangement of the fixed pulley and the sliding base, under the condition that the stroke of the sliding base is fixed, the stroke of the hydraulic oil cylinder is halved, the requirement for the rigidity of the hydraulic oil cylinder is lowered, and the bending probability of the hydraulic oil cylinder is lowered; the stability of the hydraulic oil cylinder for driving the sliding base to move is further enhanced.

The invention relates to the technical field of feed trays, and discloses a novel feed tray detection device, which comprises an adjustable bracket used for mounting and supporting the detection device and avoiding a vibration source; the connecting support and the adjustable support are installed in a hinged mode, the connecting support is used for adjusting the detection angle of the detection device, a mounting plate is installed on one side of the connecting support, and the relative height of the mounting plate and the connecting support is adjustable; the pendulum component is arranged on the side surface of the mounting plate and is rotationally connected with the mounting plate; according to the invention, the problems of unstable material quantity and high alarm rate caused by similar colors and different heights of products in traditional optical fiber detection are comprehensively solved through a plurality of adjusting structures (the adjusting pipe has multiple gears, and the angle and height of the connecting bracket are adjustable) and different state designs (vertical / inclined / universal ball structures) of the pendulum component, and the production efficiency is effectively improved.

The application discloses a kind of wire tin-coating quick cooling mechanism, including fixedly arranged on base frame and air-cooled track, the upper end of frame is provided with traction assembly, wire is after being coated with tin in base and is connected with traction assembly again after passing air-cooled track upward, further include: flap, which is hinged with air-cooled track, for controlling the opening and closing of the side of air-cooled track;Isolation component is isolated and arranged in air-cooled track, and a plurality of air holes for communicating outside air with positioning channel are symmetrically arranged on the side wall thereof for wire to pass through.The application can close the open side of air-cooled track when air-cooled track is working, and under the cooperation of first blowing assembly and second blowing assembly, the airflow in air-cooled track blows from middle to up and down sides, so that the wire is balanced, in addition, the airflow opposite to the upper and lower ends can pull the wire tight to the two ends, to avoid wire relaxation.

This invention relates to the field of polishing equipment technology, and discloses a multi-faceted polishing fixture for watch cases, including a processing box. A silicone mesh plate is located in the center of the inner side of the processing box, and a placement seat is provided on the silicone mesh plate. Multiple processing chambers for individually processing the watch case are equidistantly arranged on the placement seat. By adding and setting a front-end processing mechanism, which uses alkaline cleaning water immersion combined with ultrasonic vibration and a circulating filtration structure, various oil stains and impurities such as cutting fluid and release agents remaining on the surface and crevices of the watch case can be thoroughly removed, eliminating polishing slippage and surface dulling caused by oil residue. Secondly, relying on constant-temperature liquid immersion, the thin-walled watch case is heated evenly throughout, thoroughly and evenly releasing residual metal stress from previous processing, avoiding subsequent polishing deformation caused by uneven stress release. Simultaneously, it optimizes the polishing process, reduces grinding head vibration, and eliminates wavy lines and light / dark layer defects on the watch case surface.

This utility model relates to the field of wind turbine technology and proposes a wind turbine blade tip demolding and cutting-free hoisting device. It includes a hoisting frame with an electric hoist installed inside, and further includes a hook, a slide, a lifting mechanism, a buffer head, and a moving mechanism. The hook is located at the bottom of the electric hoist. Two slides are provided, each slidably mounted within the hoisting frame via a sliding assembly. The sliding assembly supports the two slides for lifting and lowering within the hoisting frame. The lifting mechanism is mounted on the hoisting frame. Each slide has two buffer heads via two support mechanisms. The moving mechanism is located at the bottom of the hoisting frame. This technical solution addresses the problem in the prior art where, during the process of lifting the blade tip from the mold, the blade tip is prone to vibration and swaying due to the influence of the blade material, which damages the strength of the blade tip and easily leads to a decrease in hoisting stability.

The utility model discloses a high-precision numerical control machining center with strong anti-tremble capability, which relates to the technical field of machining centers, and comprises a base, a working table arranged on the base, a movable supporting table arranged below the working table and used for supporting the working table, and a machine table arranged on the base and used for supporting the movable supporting table, a Y-axis moving mechanism used for driving the workbench to move along the Y axis is arranged on the movable supporting table, an X-axis moving mechanism used for driving the movable supporting table to move along the X axis is arranged on the machine table, the Y-axis moving mechanism is relatively perpendicular to the stand column, the X-axis moving mechanism is relatively parallel to the stand column, and the X-axis moving mechanism is located below the Y-axis moving mechanism. The movable supporting table can be supported by the machine table all the time, it is guaranteed that tremor generated during machining can be transmitted to the machine table and the base, and therefore tremor borne by the workbench is reduced.

The utility model relates to the technical field of polishing equipment, specifically disclose a kind of polishing head driving device, including support column, rotary seat, driving mechanism and positioning damping mechanism;Rotary seat is sleeved in support column outside;Driving mechanism is located in support column;The driving end of driving mechanism is connected rotary seat;Positioning damping mechanism includes driving adjustment assembly and positioning damping piece, driving adjustment assembly is located in support column, the driving end of driving adjustment assembly is connected positioning damping piece, for driving positioning damping piece close and abut on rotary seat or away from rotary seat.In the utility model, when need to accurately position polishing head on station, through driving adjustment assembly driving positioning damping piece abuts on rotary seat, to deadlock rotary seat, to facilitate the positioning adjustment of polishing head, positioning damping piece can also stop blocking the displacement or tremor of rotary seat, reduce the tremor amplitude of driving mechanism and polishing head, to improve the processing quality of the product to be processed, also avoid the breakage of the product to be processed.
