Quick clamping bench vice

Abstract

The invention discloses a quick clamping bench vice. The quick clamping bench vice comprises a fixed vice body, a moving vice body and a guide rail seat. Inclined guide rail grooves arranged in the direction of the center line are formed in the side, located at the moving vice body, of the guide rail seat. An upper cover plate is fixed to the upper end of the moving vice body. Two symmetrical slideway holes are formed jointly by the upper cover plate and the moving vice body. Sidable telescopic slide rods are arranged in the slideway holes. The extension ends of the telescopic slide rods are fixedly connected with a stretchable vice jaw plate. The rear end of the middle portion of the stretchable vice jaw plate is provided with a fine adjustment screw rod. The fine adjustment screw rod penetrates through the moving vice body and is fixedly connected with a hand wheel. A turnover clamping plate capable of turning over up and down is arranged on the side, located at the hand wheel, of the moving vice body. The turnover clamping plate can slide into the corresponding inclined guide rail groove to be clamped. A rotary base conducting rotating and locking through an oblique tooth clamping cap and an oblique tooth clamping seat is fixedly arranged below the guide rail seat. The quick clamping bench vice provided by the invention can realize quick clamping and dismantling of workpieces and is easy to operate, safe and reliable, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a fast clamping bench vise, in particular to a bench vise capable of fast rotation and fast clamping. Background technique [0002] Before machining, it is necessary to clamp and position the blank. For example, a rotatable and fast clamping bench vise is disclosed in the application number 201310658940.5. This clamp can ensure sufficient clamping force to tighten the workpiece reliably. , which greatly shortens the time required for clamping the workpiece, especially suitable for occasions where the size of the blank is frequently changed; and the structure is simple and compact, the appearance is beautiful, and the manufacturing cost is low; the parts are easy to replace after wear; but this kind of fixture needs to be lifted in advance when changing the blank When the clamping plate is moved to a fixed position, it is necessary to align the clamping plate with the teeth of the guide rail, which is troublesome to operate, and...
