1results about How to "Expanded size range" patented technology

The application provides a gear synchronous transmission anti-clamping laser pipe cutting chuck, which comprises a front cover, a rear cover, a connecting shaft for fixedly connecting the front cover and the rear cover, two pairs of clamping claws for clamping a pipe, an actuating cylinder for providing a power source, a synchronous driving mechanism for synchronously transmitting the driving force of the actuating cylinder to the clamping claws, and an anti-clamping mechanism for limiting the stroke of the synchronous driving mechanism and thus limiting the stroke of the clamping claws; the synchronous driving mechanism comprises an ear seat connected with the actuating cylinder, a push rod connected with the ear seat, a synchronous driving gear wheel in transmission connection with the push rod, four driven gear wheels in meshing connection with the synchronous driving gear wheel, one pawl fixedly arranged on each of the driven gear wheels, and four sliders slidably arranged on the front cover; the four pawls are in transmission connection with the four sliders respectively; and one clamping claw is fixedly arranged on each of the sliders. The application has high transmission efficiency and synchronous precision, is suitable for machining pipe fittings with a large size range, and can be effectively used for clamping thin pipes or fragile pipe fittings.
