Description

Technical Field

[0001] The utility model relates to the technical field of bench vises, in particular to a new type of bench vise for metalworking practice clamping. Background Art

[0002] Metalworking practice is an important practical course for engineering students, and the clamping bench vise is one of the commonly used tools in metalworking practice. A bench vise, also known as a vise, is a general-purpose fixture installed on a workbench for clamping workpieces and is an essential tool in a fitter's workshop. Its structure mainly consists of a vise body, an angle adjustment base, a lead screw, a jaw body, etc. In metalworking practice, students need to use various tools to process metal materials, such as sawing, filing, chiseling, drilling, etc., and the role of the bench vise is to firmly clamp the workpiece and provide stable support for these processing operations. The vise body of some bench vises can also rotate, enabling the workpiece to be rotated to a suitable working position. When using a clamping bench vise, it is necessary to firmly fix it on the vise table to ensure that there is no loosening phenomenon during the processing. By using a clamping bench vise, students can better carry out metalworking practice operations, improve their practical hands-on ability, and at the same time can more deeply understand and master the processes and methods of metal processing.

[0003] For example, patent CN213673666U discloses an adjustable bench vise, which includes a connecting chassis. The top of the connecting chassis is fixedly provided with an angle adjustment base. The top of the angle adjustment base is provided with a sliding seat. One end of the sliding seat is provided with a fixed jaw. An adjustable jaw is slidably arranged on the sliding seat. One end of the adjustable jaw is rotatably provided with a threaded rod. The threaded rod extends to the other end of the sliding seat, and the other end of the sliding seat is connected to the threaded rod through a threaded bushing. The end of the threaded rod is provided with a handle. In the utility model, a movable chuck that can be flexibly disassembled and assembled is designed, and the movable chuck can be flexibly installed and disassembled. The movable chuck made of a material suitable for the processing requirements of the workpiece can be replaced according to the processing needs, which is more convenient to use and the disassembly is quick and convenient; in addition, a retractable storage box is designed inside the angle adjustment base, and movable chucks of various different materials can be placed in the storage box for storage, which is convenient to take and replace at any time and is more convenient.

In addition, the existing adjustable bench vise cannot rotate, which is not convenient for fitters to operate flexibly during processing. Therefore, there is a certain room for improvement.
