This utility model relates to the field of maintenance equipment technology and discloses a linear sliding table type mobile maintenance centering platform, including a platform base. Universal casters are evenly installed around the bottom of the platform base, and a tool storage compartment is provided at the top of the platform base. An installation platform is located on top of the platform base, and the installation platform is connected to the platform base via a set of lifting cylinders. This utility model uses a lifting cylinder assembly to connect the platform base and the installation platform, making the lifting of the installation platform more flexible and convenient. The lifting handle allows for adjustment to the optimal ergonomic operating height, accommodating operators of different heights and preventing muscle injury. A ball screw assembly drives two fitter platforms to move relative to each other, enabling direct engagement and rapid centering of equipment one and equipment two mounted on the fitter platforms, saving significant centering time, ensuring installation accuracy, and meeting user needs based on different equipment types.

This invention discloses a rotary pneumatic fixture for workpiece positioning and clamping. The base consists of an adapter plate, a lifting block, a base plate, and pads. A rotary cylinder drives a pull rod and a pressure cap on the base plate to vertically clamp the workpiece. Pairs of clamping blocks on the pads synchronously and balancedly clamp the workpiece under the action of springs and limit blocks. Positioning blocks pre-position the workpiece. By replacing or adjusting the lifting block, pads, pressure cap, and clamping blocks, it can accommodate workpieces of different sizes and shapes and can be quickly installed on automated production lines, improving processing accuracy and efficiency.
