Embodiment Construction

[0047] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples or drawings are used to illustrate the present invention, but not to limit the scope of the present invention.

[0048] like figure 1 , 2 As shown, it includes an I-shaped mounting plate 1, an inner clamping mechanism 2, an outer clamping mechanism 3, a base 4, and a motor 7, wherein the lower end of the base 4 is fixedly installed on the frame of the machine tool, as figure 1 As shown, the motor 7 is installed on the inner side of the base 4; the I-shaped mounting plate 1 is installed on the output shaft of the motor 7, and the I-shaped mounting plate 1 is rotatably matched with the base 4; image 3 , 4 As shown, the inner clamping mechanism 2 and the outer clamping mechanism 3 are installed on the I-shaped mounting plate 1 .

[0049] like image 3 , 4 As shown, the above-menti...

Abstract

The invention belongs to the technical field of clamps, and particularly relates to a quick clamping clamp which comprises an I-shaped mounting disc, an inner clamping mechanism, an outer clamping mechanism, a base and a motor. A limiting block is designed to always keep an inclined state relative to a corresponding arc-shaped rack under the action of two plate springs and deviates to the side on which a first clamping arc plate is mounted; it is guaranteed that after the arc-shaped racks move upwards, thrust far away from a telescopic outer sleeve is provided for corresponding telescopic inner rods, and the clamping force of first clamping arc plates installed on the telescopic inner rods on the inner wall face of a workpiece is improved; by means of the self-locking function of a first worm and a first worm gear, the three arc-shaped racks can be limited and locked, and the situation that the three arc-shaped racks are pressed to move reversely, and clamping of the workpiece by the inner clamping mechanism is affected is prevented; and by means of the self-locking function of a second worm and a second worm gear, the three racks can be limited and locked, and the situation that the three racks are pressed to move reversely, and clamping of the workpiece by the outer clamping mechanism is affected is prevented.

Description

[0001] Technical field [0002] The invention belongs to the technical field of clamps, in particular to a quick clamping clamp. 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 fast clamping and...
