Description

Vice device {VICE DEVICE}

The present invention relates to a vise apparatus, in which a gap adjusting groove is formed in a guide rail to adjust an initial setting interval of the moving tank, and a separate pressing block is provided inside the moving tank to firmly hold the workpiece Vise device.

Generally, the vise is configured such that the movable member is slid along the guide groove by unscrewing and screwing the screw shaft coupled to the female screw of the mount portion, thereby clamping the workpiece by adjusting the distance between the movable member and the fixed member. In the case of a finished vise, it takes a long time to rotate the screw shaft one by one according to the size of the workpiece, thereby causing a remarkable reduction in the work efficiency.

Therefore, in order to quickly adjust the spacing of the movable member from the fixing member, it has already been disclosed in the Utility Model No. 1989-0001227 'Desktop Vice' and the Utility Model Registration No. 20-0214028 'Speed Vice'.

However, in the case of the utility model room 1989-0001227 'desktop vise', the female screw is connected to the elevating rod to which the elasticity of the coil spring is applied, so that the female screw is lowered by the action of the operating rod, And the clamping or unclamping is performed by operating the bellows. This complicates the construction for quick clamping operation of the movable jaw, resulting in an increase in the manufacturing cost at the time of manufacture. Therefore, the price competitiveness of the product is deteriorated and the clamping or unclamping In particular, since the female screw retains the coupling force with the screw rod due to the elastic force of the coil spring, it is difficult to secure the screw shaft for clamping the workpiece. It causes frequent malfunctions, as well as strong clamping of the workpiece It can not be made because not be able to function properly as a vise.

In the case of the "speed vise" of utility model registration No. 20-0214028, a screw for operating the movable jaw is connected to the body by a screw, a compression spring, a compression nut, a split nut, The split nut is opened by the unlocking of the adjustment handle so that the clamping is performed by the operation of the moving jaw by the screw. This also complicates the structure for the quick clamping operation of the moving jaw, And for the clamping or unclamping operation, it is very inconvenient to use the split nut by interlocking and unscrewing the adjustment handle screwed into the body, so that the divided split nut is divided into two parts for clamping operation When the adjustment handle is tightened with the screw, the frictional resistance with the screw is large In that they do not have to problems such as the operation flexibility can not be achieved, as well as not be able to be a strong tightening of the screw with the relaxation during the clamping of the work of the control handle for a flexible operation that leads to the deterioration as a vice.

In addition, a general vise is constructed such that a screw is provided at the center of the side surface of the movable jaw so as to clamp the work (workpiece) by the pressing force of the screw applied to the central portion of the movable jaw.

However, the pressing structure of such a machining jig and screw has a problem that a pressing force is concentrated on a central portion of the machining jig and the pressing force applied to the work is lowered.
