What is the use method of flat jaw vice in precision parts processing
Pneumatic or hydraulic vises shall be generally used in mass production of precision parts processing. Pneumatic or hydraulic vises shall be used. The structure and adjustment method of vises shall be familiar with. For example, hydraulic vises can be used to effectively reduce labor intensity, stabilize clamping force and absorb certain vibration during milling for workpieces with large impact force and heavy dead weight in mass production.
According to the drawings and instructions, the structural principle of the hydraulic vise is analyzed as follows: during the clamping operation, pull the handle to the clamping position, the pressure oil enters the oil chamber above the piston 2 through the control valve 1, pushes the piston 2 to move downward, and drives the piston rod 3 connected to it to move. After the piston rod pushes the sliding block 4 with the chute to move, under the action of the chute and the roller 6, pull the movable jaw seat 5 to the left to clamp the workpiece.
After the end of the milling stage in the process of precision parts processing, pull the handle to the released position, the piston returns, and the jaw is released. When processing another batch of workpieces, if the distance between the two jaws needs to be adjusted due to the change of workpiece size, loosen the nut on the upper end of the T-shaped column shaft in the middle of the roller seat 7, so that the teeth on the roller end face are separated from the teeth on the movable jaw seat, and then the position of the movable jaw can be adjusted.
