This invention discloses a laser cutting machine for precision workpiece machining, capable of automatically positioning the workpiece. It relates to the field of precision workpiece machining technology and includes a worktable and a positioning assembly. A support roller is rotatably connected to the center of the worktable, and a waste bin is located below the worktable. A three-axis slide module is installed at the rear of the worktable, and the output end of the three-axis slide module is connected to a laser cutting head. During positioning, the drive motor first drives the two slide blocks to move synchronously towards each other via positive and negative threaded screws. A buffer spring pushes the roller frame and its rollers to contact the workpiece. The buffer spring, with its low elastic coefficient, ensures a gentle contact force. After initial positioning, the slide blocks continue to move, compressing the buffer spring. The drive slotted plate, through rollers, drives the positioning seat and positioning plate to complete the final rigid clamping. This process of first guiding and then locking can complete high-precision automatic centering within seconds, resulting in high positioning accuracy.

The utility model relates to optical fiber technical field especially relates to a kind of optical fiber fixing mechanism and fiber distribution box, including the support plate of being set in pairs, vertical lifting has lifting plate on support plate top, the same mounting plate is fixedly connected on the opposite side wall of two lifting plates, the same recessed plate is fixedly connected on the opposite side wall of two support plates, mounting plate and recessed plate opposite side are provided with several limit plates;Further include: drive assembly, drive assembly drives the synchronous lifting of two lifting plates;Moving assembly, moving assembly makes one of the limit plate on mounting plate can be individually vertically moved.The utility model is compared to the fiber distribution box in prior art, only single rotation is needed to realize the synchronous limit clamping of multiple optical fibers, avoids the tediousness of one by one operation, while effectively avoiding to loosen all optical fiber clamping during maintenance, prevent the situation that optical fiber line is in disorder, make optical fiber maintenance more accurate and efficient.

This utility model relates to the technical field of irregular part processing devices, specifically an adaptively adjustable thin-walled irregular part clamp, including a mounting plate. Two mounting frames are symmetrically slidably mounted on the top of the mounting plate. At least six first hydraulic cylinders are installed inside the mounting frames. The piston rods of the first hydraulic cylinders all point towards the center of the mounting plate, and a contact module is fixedly installed at the end of the piston rod of each hydraulic cylinder. This utility model achieves multi-directional and uniform clamping force on the thin-walled irregular part by setting at least six first hydraulic cylinders pointing towards the center of the mounting plate within the mounting frames. The contact module and pressure sensor at the end of the piston rod of each hydraulic cylinder can monitor the clamping force in real time, preventing deformation or damage to the thin-walled irregular part due to excessive clamping force. Simultaneously, the extension and retraction of the hydraulic cylinders can be flexibly adjusted according to the pressure data to adapt to thin-walled irregular parts of different shapes and sizes, ensuring clamping stability and accuracy.

This utility model discloses a welding fixture for radiators of engineering vehicles and commercial vehicles, including a base and a support platform. A worktable is installed on the horizontal surface of the support platform, and a lifting seat is provided on the vertical surface. Several end-face positioning rods of gradually varying lengths are installed on the lifting seat. A fixed seat is installed on the worktable, and a sliding seat that slides with the worktable is provided above the fixed seat. Clamping seats are respectively installed at both ends of the sliding seat. A support block is fixedly installed on the bottom front side of each clamping seat. Side positioning blocks are fixedly installed on the middle front side of two clamping seats on the same sliding seat. Side clamping mechanisms are provided on the front side of two clamping seats on another sliding seat, corresponding to the side positioning blocks. A top clamping mechanism is fixedly installed on the rear side of the clamping seat, and the top clamping block of the top clamping mechanism corresponds to the support block. This utility model is suitable for clamping products of the same type but different sizes, while ensuring clamping accuracy and facilitating subsequent automated welding.
