Description
Technical Field
The invention relates to a bench vice.
Background
Bench vice, also called vice, bench vice. Bench vices are universal fixtures used to hold work pieces. The device is arranged on a workbench and used for clamping and stabilizing a processed workpiece, and is a necessary tool in a bench work shop. The turntable type clamp body can rotate to enable the workpiece to rotate to a proper working position. The structure of the clamp consists of a clamp body, a base, a guide nut, a screw rod, a clamp jaw body and the like. The movable clamp body is in sliding fit with the guide rail of the fixed clamp body through the guide rail. The screw rod is arranged on the movable clamp body, can rotate but cannot axially move, and is matched with a screw rod nut arranged in the fixed clamp body. When the handle is rocked to rotate the screw rod, the movable clamp body can be driven to axially move relative to the fixed clamp body, so that the clamping or loosening effect is achieved. The spring is fixed on the screw rod by virtue of the check ring and the cotter pin, and the spring has the function of enabling the movable clamp body to timely withdraw when the screw rod is loosened. The fixed clamp body and the movable clamp body are respectively provided with a steel clamp jaw and are fixed by screws. The working surfaces of the jaws are provided with cross reticulate patterns, so that the workpiece is not easy to slide after being clamped. The jaw is hardened by heat treatment, and has better wear resistance. The fixed clamp body is arranged on the swivel base and can rotate around the axis of the swivel base, and when the swivel base rotates to a required direction, the clamping handle is pulled to enable the clamping screw to be screwed, so that the fixed clamp body can be fastened under the action of the clamping disc. Three bolt holes are arranged on the swivel base and are used for being fixed with the clamp table. However, the bench vice on the market at present basically adopts a screw nut to realize the approaching and separating of the movable jaw and the fixed jaw to clamp or release the workpiece, so that the working efficiency of the bench worker is greatly reduced due to the fact that the bench vice is slow in idle stroke advancing. Although some technical improvements for improving the idle stroke progress exist at present, the general technical improvement is larger, the structure is complex, and the technical improvement cost is higher, such as the patent with publication number of CN 207058118U: a rapid clamping bench vice comprises a fixed lead body, a movable lead body and a guide rail seat; the guide rail seat is provided with an inclined guide rail groove arranged at one side of the movable lead body; an upper cover plate is fixed at the upper end of the movable lead body, and two symmetrical slideway holes are formed between the upper cover plate and the movable lead body; a telescopic slide bar capable of sliding is arranged in the slide way hole, and the extending end of the telescopic slide bar is fixedly connected with a telescopic jaw plate; the rear end of the middle part of the telescopic jaw plate is provided with a fine adjustment screw rod, and the fine adjustment screw rod penetrates through the movable lead body and is fixedly connected with a hand wheel; a turnover clamping plate capable of being turned up and down is arranged on one side of the movable lead body, which is positioned on the hand wheel, and the turnover clamping plate can slide into the inclined guide rail groove to be clamped; a rotating seat which rotates and locks through the inclined tooth clamping cover and the inclined tooth clamping seat is fixedly arranged below the guide rail seat; the quick clamping bench vice can realize quick clamping and disassembly of workpieces, is simple to operate, safe and reliable, improves the working efficiency, but has large technical improvement degree, complex structure and higher technical improvement cost. As further described in publication number CN 103659376B: a rotatable rapid clamping bench vice, which comprises a base component, a guide rail, a locking clamp body and a movable clamp body; the guide rail is provided with guide rail teeth which are distributed along the central line direction of the guide rail; the locking pliers are arranged at one end of the guide rail far away from the guide rail teeth; the movable clamp body is slidably arranged on the guide rail; the locking pliers body is provided with a cam and a movable clamping plate; the movable clamp body is provided with a fixed clamping plate and a clamping plate; according to the rotatable rapid clamping bench vice, the locking clamp body and the movable clamp body are matched, the guide rail teeth are used for positioning, and the cam arranged on the locking clamp body drives the movable clamping plate to clamp a workpiece, so that the rapid clamping of the workpiece is realized, the workpiece is always in the most convenient processing position, a large amount of workpiece clamping time is saved, and the working efficiency is improved. However, the device still has the problems of large technical improvement degree, complex structure and high technical improvement cost.
