Abstract
The utility model discloses a kind of fixture, comprise clamp, described clamp is I shape, its both sides, upper end are provided with vertical screwed hole, described screwed hole is formed with screw rod and is threaded, and described screw rod upper end is laterally provided with hand lever, and lower end is provided with chuck, the hyperbolic configuration that the cross section of described clamp middle standing pillar is symmetrical set, the rectangular configuration that the both sides of this hyperbolic configuration are symmetrical set.This fixture is easy to carry and places, and is the manual light instrument of student; Two workpiece can be clamped simultaneously, be convenient to process in turn, raise the efficiency; The particularly clamp pillar construction of optimal design after finite element analysis, material is economized, and intensity is high.
Description
Technical field
The utility model relates to a kind of fixture, belongs to clamping device technical field.
Background technology
Professional colleges focuses on the cultivation of students ' practical ability, and so just need a kind of fixture being easy to carry and fixing, no matter be in classroom, or dormitory all can be arranged on desk easily, and the workpiece that will make is clamped, and then carries out filing and polishing etc. to workpiece.
Summary of the invention
The utility model makes the needs of workpiece by hand in order to meet Vocational College Students, provide a kind of fixture.
The utility model solves the technical scheme that its technical problem adopts: a kind of fixture, comprise clamp, described clamp is I shape, its both sides, upper end are provided with vertical screwed hole, described screwed hole is formed with screw rod and is threaded, and described screw rod upper end is laterally provided with hand lever, and lower end is provided with chuck, the hyperbolic configuration that the cross section of described clamp middle standing pillar is symmetrical set, the rectangular configuration that the both sides of this hyperbolic configuration are symmetrical set.
Further, described clamp both sides, bottom by screw and base plate fastening.
Further, the side of described clamp column is provided with two round open-works.
The beneficial effects of the utility model are, this fixture, are easy to carry and place, and are the manual light instruments of student; Two workpiece can be clamped simultaneously, be convenient to process in turn, raise the efficiency; The particularly clamp pillar construction of optimal design after finite element analysis, material is economized, and intensity is high.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is a kind of fixture front view of the utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
As shown in Figure 1, a kind of fixture, comprises clamp 5, clamp 5 is in I shape, and its both sides, upper end are provided with vertical screwed hole, and screwed hole is formed with screw rod 2 and is threaded, screw rod 2 upper end is laterally provided with hand lever 1, and lower end is provided with chuck 3, and the both sides, bottom of clamp 5 are fastening by screw 4 and base plate 6.The side of clamp 5 column is provided with two round open-works 51, is convenient to hang on wall or on Working gantry.
Due to fixture sandwich workpiece, the compound action of middle standing pillar under tension and moment of flexure, presents complex stress condition, very easily ruptures, and applies finite element software for this reason and carries out force analysis.As shown in Figure 2, the hyperbolic configuration that after optimizing, the cross section of clamp 5 middle standing pillar of design is symmetrical set, the rectangular configuration that the both sides of this hyperbolic configuration are symmetrical set.
Lain in by fixture on work top, two workpiece are placed on below chuck 3 respectively, rotate hand lever 1, screw rod 2 moves down, chuck 3 workpiece pressing, then just can carry out filing and polishing to workpiece; After processing workpiece, counter-rotation hand lever 1, unclamps workpiece, is unloaded.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any equivalent replacement done and improvement, all should be included within protection domain of the present utility model.
