Description

Bench vice

Technical Field

The invention relates to a bench vice.

Background

The bench vice is also called vice or bench vice. A vise is a universal fixture used to clamp workpieces. The device is arranged on a workbench and used for clamping and stably processing workpieces, and is a necessary tool for a bench worker workshop. The turntable type clamp body can rotate, so that the workpiece can rotate to a proper working position. The structure of the clamp consists of a clamp body, a base, a guide nut, a lead screw, a clamp opening body and the like. The movable pliers body is in sliding fit with the guide rail of the fixed pliers body through the guide rail. The lead screw is arranged on the movable caliper body, can rotate but cannot axially move, and is matched with a lead screw nut arranged in the fixed caliper body. When the handle is shaken to rotate the screw rod, the movable vice body can be driven to move axially relative to the fixed vice body, and the clamping or loosening effect is realized. The spring is fixed on the screw rod by the aid of the retainer ring and the split pin, and the spring has the function of enabling the movable pliers body to timely withdraw when the screw rod is loosened. The fixed pliers body and the movable pliers body are respectively provided with a steel jaw and are fixed by screws. The working surface of the jaw is provided with crossed reticulate patterns, so that the workpiece is not easy to slide after being clamped. The jaw is hardened through heat treatment, and has better wear resistance. The fixed clamp body is arranged on the rotary seat and can rotate around the axis of the rotary seat, when the fixed clamp body rotates to a required direction, the clamping handle is pulled to enable the clamping screw to be screwed tightly, and the fixed clamp body can be fastened under the action of the clamping disc. The rotary seat is provided with three bolt holes for fixing with the clamp platform. However, in the existing bench vices on the market, the movable jaw and the fixed jaw are basically close to and far away from each other by adopting the screw nut to clamp or release the workpiece, so that the workpiece is very slow in idle running, and the working efficiency of a bench worker is greatly reduced. Although some technical improvement solutions for improving the lost motion process exist at present, the general technical improvement is large, the structure is complex, and the technical improvement cost is high, for example, patent with publication number 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 oblique guide rail grooves arranged on 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 slide way holes are formed between the upper cover plate and the movable lead body; a telescopic sliding rod capable of sliding is arranged in the sliding channel hole, and the extending end of the telescopic sliding rod 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; the movable lead body is provided with an overturning clamping plate which can be overturned up and down and is positioned on one side of the hand wheel, and the overturning clamping plate can slide into the inclined guide rail groove to be clamped; a rotating seat which is rotated and locked through a helical tooth clamping cover and a helical tooth clamping seat is fixedly arranged below the guide rail seat; quick clamping bench vice, can realize the quick clamping and the dismantlement of work piece, easy operation, safe and reliable has improved work efficiency, but the technique degree of improving is big, the structure is complicated, the technique cost of improving is higher. Further patent publication No. CN 103659376B: a rotatable rapid clamping bench vice comprises a base assembly, a guide rail, a locking vice body and a movable vice body; the guide rail is provided with guide rail teeth which are arranged along the central line direction of the guide rail; the locking pliers body is arranged at one end of the guide rail, which is 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 clamp plate and a clamping plate; according to the rotatable rapid clamping bench vice, the locking vice body is matched with the movable vice body, the guide rail teeth are used for positioning, the cam arranged on the locking vice body drives the movable clamping plate to clamp a workpiece, rapid clamping of the workpiece is achieved, the workpiece is always located at the most convenient machining position, a large amount of workpiece clamping time is saved, and the working efficiency is improved. But still have technical improvement degree, the structure is complicated, technical improvement cost's problem higher.
