The structure and technical analysis of the use of Web jaws pliers, the more detailed the better, thank you!
Clamp structureThe clamp assembly structure is a detachable threaded connection and pin connection; linear motion of movable clamp body is changed by spiral motion; the working surface is the friction surface of screw, guide and clearance of shaft and hole. Clamp composition concise, compact structure.
The working principle of the clampThe screw rod is rotated by a wrench, and the movable clamp body is moved by the screw nut to form the tightening and loosening of the workpiece. The size of the workpiece to be clamped shall not exceed 70 millimeters.
The use of pliersAlso known as machine vise clamp, is a common fixture, commonly used in the installation of small parts. It is a random attachment of milling machines and drilling machines. Fix it on the machine table to clamp the workpiece and do the cutting.
Is not inside clamp forcepsUsually, the bench vice is used as a locksmith fixture and is suitable for the clamping and positioning of manual work.Vise is a universal fixture for machine tool, and machine tool with the use of more use of milling and planing machine. The characteristics of working face no cut face, the high accuracy than, and the similar, and drive the way they are all the same.
Note clamp clamping workpiece:(1) the machined surface of the workpiece must be higher than the jaw; otherwise, the workpiece should be padded with a parallel pad.(2) in order to hold the clamp firmly and prevent the workpiece from loosing during the planing, the flat surface must be put on the pad and jaw. To make the workpiece tightly on the pad iron, should side clamping, with a hand hammer to tap workpiece sub surface, smooth plane with copper to prevent knock knock to smooth surface.(3) in order not to damage the jaw and maintain the machined surface, the copper is pressed at the jaw at the time of clamping the workpiece.D, hand move the iron pad to check the clamping degree, such as loose, between the workpiece and the pad iron don't fit well, should loosen the clamp to clamp(4) lack of rigidity: the workpiece needs to be clamped so as to avoid clamping force to deform the workpiece.
