Description

Technical Field

[0001] The utility model relates to the technical field of bench vises, in particular to a quick vise changing device for a machine bench vise. Background Art

[0002] The existing bench vise is also called a bench vise. The bench vise is a universal fixture used to clamp the workpiece. It is installed on a workbench to clamp the workpiece for processing. When the bench vise is operated, the movable clamp plate is moved to the position of the fixed clamp plate through the moving adjustment mechanism to clamp the workpiece, so that the workpiece is processed and tightened by the bench vise, thereby improving the processing operation of the bench vise when processing the workpiece.

[0003] According to the patent with application number 202223289350.3, a bench vise is disclosed, including a bench vise body, wherein the bench vise body includes a fixed seat, an operating plate seat and a movable clamp plate, wherein the operating plate seat is rotatably connected to the upper surface of the fixed seat, and the movable clamp plate is arranged at one end of the upper surface of the operating plate seat. The bench vise body is also provided with: a fastening mechanism, and the fastening mechanism facilitates the pressing assembly and the locking assembly, and the fastening mechanism is arranged at the edge of the fixed seat; a clamping mechanism, and the clamping mechanism includes a clamping assembly and an installation assembly, and the clamping mechanism is arranged on the movable clamp plate.

[0004] The above scheme is adopted to solve the problem that the operator is prone to increase the force to adjust the pressing operation and rotate the vise to the operating direction during the pressing operation of the bench vise in the prior art, and the fixing bolts are loosened due to the influence of external force when the bench vise is installed and used, and the bench vise is unstable and shakes when in use, thereby affecting the fastening, clamping and reinforcement operation of the workpiece through the bench vise. When the elastomer provided in the above scheme is severely worn, the elastomer needs to be disassembled and replaced. However, the above scheme adopts the method of fixing the elastomer with screws, and when replacing it, a screwdriver or other tool needs to be used to tighten or loosen it, which will cause a long time in the disassembly process. If the elastomer cannot be disassembled and replaced quickly, the operator will have to spend a lot of time to disassemble and reinstall it, and this cumbersome process will cause work to stop, greatly reducing production efficiency, and there are certain shortcomings. To this end, we provide a machine bench vise quick clamp changing device to solve the above problems. Utility Model Content
