A bench vise for labor technology

Abstract

The invention discloses a bench vice for labor skills. According to the key points of the technical scheme, the bench vice comprises a baseplate, a plurality of fixed pincers connected to the baseplate fixedly, and a plurality of movable pincers connected to the baseplate slidably; the fixed pincers and the movable pincers are arranged in an one-to-one corresponding manner, and the baseplate is rotatably connected to a rotating disk; the rotating disk is provided with a plurality of hinge bars used for driving the movable pincers to slide, and the two ends of each hinge bar are hinged to the rotating disk and the corresponding movable pincers separately; the fixed pincers, the movable pincers and the hinge bars are uniformly distributed around the rotating disk annularly, and the movable pincers are located between the fixed pincers and the rotating disk; any group of the fixed pincers and the movable pincers, arranged correspondingly, are provided with driving screw rods of which thelength direction is consistent with the sliding direction of the movable pincers; and the driving screw rods are fixedly and circumferentially connected to the axes of the movable pincers rotatably, and are in screw joint with the fixed pincers. According to the bench vice, a plurality of workpieces of the same type can be machined by a plurality of students simultaneously, and the overall practice efficiency of the labor skills of the students is improved.

Description

technical field [0001] The invention relates to the field of clamps, and more specifically relates to a bench vise for labor technology. Background technique [0002] Labor technical education is an important content and part of the basic education stage, and has been listed by the Ministry of Education as a nationally designated learning field in comprehensive practical activities. The labor skills class takes operability and practicality as the leading learning method, aims at cultivating students' correct labor technology awareness and innovative thinking ability, and takes students to obtain positive labor experience and form good technical literacy as the main goal. Comprehensive development has a unique role. Therefore, the main content of labor skills teaching is to let students experience the glory and fun of labor and learn to cooperate in the practice of hands-on operation, so as to cultivate students' comprehensive quality and ability. [0003] In the teaching o...

Problems solved by technology

The bench vise is usually installed on the workbench to clamp the workpiece so that people can process the workpiece. The existing bench vise is usually only used by one person to operate the same workpiece. When students practice labor skills, they usually Process multiple workpieces of the same type for multiple students. If the number of vises is not enough, students need to wait in line for processing, resulting in low efficiency of students' labor practice
