Description
Technical field
The utility model belongs to the fixing technical field of workpiece.
Background technology
Before workpiece is processed again, usually need to be fixed by hold down gag.Existing hold down gag comprises the depression bar be hinged on base, is compressed by workpiece by the rotation of depression bar.
When operating, if the pin joint of depression bar is higher than the lowest surfaces of workpiece, can ensure that one end of depression bar can offset with workpiece all the time, but one end scope of activities of depression bar and absorption surface is narrower.If the pin joint of depression bar is lower than the lowest surfaces of workpiece, although one end scope of activities of depression bar and absorption surface is wider, likely can not offset with workpiece in a certain section of scope of rotating.Still wish that a kind of one end scope of activities of depression bar and absorption surface that can make is wider, make again the hold down gag that one end of depression bar and absorption surface can offset with workpiece all the time.
Utility model content
The utility model provides a kind of floating type hold down gag, to offset with workpiece all the time conflicting problem with one end of the wider and depression bar of one end scope of activities solving depression bar and absorption surface and absorption surface.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of floating type hold down gag, comprise base, with workbench and the depression bar of locating slot, the middle part of depression bar is hinged on base, the pin joint of depression bar is lower than the locating slot of workbench, also comprise pole, subplate and the limiting plate be connected on base, limiting plate is concordant with the locating slot in the vertical direction of workbench, the hypomere of depression bar is control section, the epimere of depression bar has cylindrical void along on its width, pole is through cylindrical void, limiting plate can offset with pole, subplate covers the end of depression bar epimere, subplate is connected with the two ends of pole.
Principle of the present utility model is: when clamped condition, when one end of depression bar and absorption surface is higher than workpiece, subplate cover on depression bar with Work-sheet pressing.When one end of depression bar and absorption surface is lower than workpiece, limiting plate is concordant with the locating slot in the vertical direction for place work piece on workbench, and limiting plate can offset with pole, and subplate can lift by pole, subplate can, higher than the end of depression bar, make subplate and workpiece push against.
Compared with prior art, the utility model has the advantage of: the pin joint of depression bar is lower than the locating slot of workbench, one end scope of activities of depression bar and absorption surface is wider, and, when one end of depression bar and absorption surface is lower than workpiece, subplate can rise to push against workpiece, and one end of depression bar and absorption surface can push against with workpiece all the time.Both ensure that effective scope of activities of depression bar, in turn ensure that depression bar can offset with workpiece.
Further, also comprise spring, one end of spring is connected with the hypomere of depression bar, and the other end is connected with base, and spring is used for making depression bar away from workpiece, is convenient to workpiece and draws off.When spring is connected to away from locating slot place, spring is stage clip; When spring is connected near locating slot place, spring is extension spring.
Further, because of depression bar and subplate all may with absorption surface, therefore described depression bar and subplate are provided with rubber layer, prevent depression bar and subplate from being weighed wounded by workpiece.
Further, the control section of described depression bar is provided with the convenient handle gripped, and facilitates operated by personnel.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is the structural representation of the floating type hold down gag embodiment of the utility model.
Detailed description of the invention
Reference numeral in Figure of description comprises: base 1, workbench 2, depression bar 3, pole 4, subplate 5, limiting plate 6, stage clip 7, cylindrical void 8, locating slot 9.
As shown in Figure 1, the floating type hold down gag of the one in the present embodiment, comprises base 1, workbench 2 with locating slot 9, depression bar 3, pole 4, subplate 5, is connected to limiting plate 6 on base 1 and stage clip 7.Depression bar 3 is positioned at the right side of workbench 2, and the middle part of depression bar 3 is hinged on base 1, and the pin joint of depression bar 3 is lower than the locating slot 9 of workbench 2.Limiting plate 6 is concordant with the bottom surface in the vertical direction of workbench 2 locating slot 9.The hypomere of depression bar 3 is control section, and the control section of depression bar 3 is provided with the convenient handle gripped, and the epimere of depression bar 3 has cylindrical void 8 along on its width, and pole 4 is through cylindrical void 8, and limiting plate 6 can offset with pole 4.Subplate 5 covers the end (epimere of depression bar 3 herein refers to pin joint to be boundary, is used for and that section of absorption surface) of depression bar 3 epimere, and subplate 5 is connected with the two ends of pole 4.Depression bar 3 and subplate 5 are provided with rubber layer.One end of stage clip 7 is connected with the hypomere of depression bar 3, and the other end is connected away from locating slot 9 place with base 1.
When workpiece is clamped, depression bar 3 for rotating counterclockwise, when one end of depression bar 3 and absorption surface is higher than workpiece, subplate 5 cover on depression bar 3 with Work-sheet pressing.When one end of depression bar 3 and absorption surface is lower than workpiece, when depression bar 3 can't reach workpiece, limiting plate 6 is concordant with locating slot 9 in the vertical direction for place work piece on workbench 2, limiting plate 6 can offset with the pole 4 in cylindrical void 8, even if depression bar 3 continues to rotate counterclockwise, subplate 5 also can not continue to fall.Subplate 5 can be lifted by limiting plate 6 by pole 4, and subplate 5 can, higher than the end of depression bar 3, make subplate 5 and workpiece push against.
When designing, be close to when should note the end of subplate 5 and depression bar 3 epimere, otherwise in the process of work, subplate 5 can shake, and affects the stationarity of work.
One end of stage clip 7 is connected with the hypomere of depression bar 3, and the other end is connected away from locating slot 9 place with base 1.Stage clip 7 is used for making depression bar 3 away from workpiece, is convenient to workpiece and draws off.Because of depression bar 3 and subplate 5 all may with absorption surface, therefore described depression bar 3 and subplate 5 are provided with rubber layer, prevent depression bar 3 and subplate 5 from being weighed wounded by workpiece.The control section of described depression bar 3 is provided with the convenient handle gripped, and facilitates operated by personnel.
For a person skilled in the art; under the prerequisite not departing from the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
