The invention belongs to the technical field of clamps, and particularly relates to a clamp for a cylindrical workpiece. The clamp comprises an I-shaped mounting plate, an inner clamping mechanism andan outer clamping mechanism. When the clamp clamps the workpiece, the workpiece is sleeved with three obliquely-distributed first clamping arc plates, and the workpiece is pushed to drive three setsof telescopic structures to swing; when the three sets of telescopic structures swing to be level with the upper end face of the I-shaped mounting plate, an adjusting rod is rotated, a worm and a wormwheel are driven by the adjusting rod to drive three arc-shaped racks to move upwards, and the upwards-moved arc-shaped racks limit stretching and swinging of the three sets of telescopic structures;the inner wall of the workpiece is fixed; then driving columns mounted on a three screw rods are manually driven through a hexagonal wrench to drive the screw rods to rotate, and the screw rods rotate to drive a connecting plate to slide along the radial direction of the I-shaped mounting plate under the action of threads; the connecting plate slides to drive two second clamping arc plates installed on the connecting plate to slide to clamp the outer wall of the workpiece; and workpiece installation is completed.
Description
[0001] Technical field [0002] The invention belongs to the technical field of fixtures, in particular to a fixture for cylindrical workpieces. Background technique [0003] A machine tool fixture is a device used to clamp a workpiece on a machine tool. Its function is to position the workpiece so that the workpiece can obtain the correct position relative to the machine tool and the tool, and clamp the workpiece reliably. [0004] For some cylindrical workpieces, especially cylindrical workpieces with relatively large diameters, they are generally processed by vertical lathes; there are the following problems in clamping: [0005] First, during the clamping process, the workpiece is not easy to clamp and is easily deformed during the clamping process. [0006] Second, the clamping process of cylindrical workpieces is relatively slow and cannot be quickly clamped. [0007] It is necessary for the present invention to design a fixture for a vertical lathe that can realize f...
