The invention discloses a drilling-milling clamp for positioning and clamping a lateral surface used in a workpiece, which comprises a bottom plate (1) a positioning structure and a clamping device to carry out drilling and milling on the workpiece (11); and the lateral surface used in the workpiece (11) is positioned and clamped. The clamping device adopts a float clamping device, which means that a clamped element is a floating press block (13) capable of natural oscillation on the clamping device, and the floating press block (13) is pressed on the lateral surface of the workpiece (11) when the clamp tightly clamps. The invention also discloses a method for clamping the drilling-milling clamp. With the technical proposal, the clamp can conveniently clamp the workpiece, is particularly applicable to condition of positioning and clamping the lateral surface used in the workpiece which has an irregular clamping surface and can not be clamped by a common clamping structure. The clamp has the advantages of evenly clamping force distribution, quick clamp and high production efficiency.
Description
technical field [0001] The invention belongs to the technical field of mechanical manufacturing process equipment, and relates to a fixture structure of a machine tool. More specifically, the invention relates to a drilling and milling fixture for positioning and clamping a workpiece by a side. The present invention also relates to the clamping method of the drilling and milling fixture Background technique [0002] When mechanical parts are processed on machine tools, fixture positioning processing is often required, such as drilling fixtures and milling fixtures used in drilling and milling. However, the shape of some parts is irregular, and it needs to be positioned by the side and clamped with the corresponding side, and the surface used for clamping is uneven, or irregular, or line-shaped. The shape and position of the different parts change, which brings great difficulties to the setting of the clamping device. Contents of the invention [0003] The first problem t...
