What's the difference between a vice and a vice
In order not to damage and maintain the surface of the tongs, place the piece of copper on the clamp. D, use the hand to move the iron to check the clamping degree, if there is loose, to show that the workpiece is not good to the padded iron, should loosen the flat tongs clamp again (4) it is not enough to be rigid: the workpiece needs to be firm, so as to prevent the clamping force from deforming the workpiece. Bench vice: use: device on the workbench, used to clip the machining workpiece, for the fitter workshop essential tool. The rotary clamp can rotate to make the workpiece rotate to the appropriate position.
Note to the pincers: (1) the machined surface of the workpiece must be higher than the tongs, otherwise it shall be made of a parallel mat. (2) to prevent the workpiece from being loose when the workpiece is loose in order to hold the clamp firmly, it must be applied to the iron and tongs. To make a workpiece stick close on the pad iron should be a clamp, a hammer tap the workpiece surface, smooth plane to knock knock to prevent injury by copper bar is bright and clean surface.
The construction of flat pliers The assembly structure of flat pliers is removable thread connection and pin connection. The linear motion of the clamp body is transformed by the spiral motion; The surface of the work is the friction surface of the shaft and hole of screw, guide and clearance. As shown in figure 2-2, the pincers are simple and compact.
Use of flat tongs Pincers are also known as vice, a common fixture that is used to install small workpieces. It is a random attachment for milling machines and drilling machines. It is fixed to the machine tool workbench, and it is used for cutting and processing of the workpiece. The working principle of flat tongs Use the wrench to move the screw and move the clamps through the screw nut, forming the tightening and loosening of the workpiece. The size of the sandwiched piece shall not exceed 70 mm.
