Automatic overturning clamping apparatus
Technical field
The utility model relates to a kind of production fixture, particularly relates to one and processes for certain trestle component, the automatic overturning clamping apparatus of the upset of band hydraulic swivel and corner oil cylinder clamping.
Background technology
Certain wind-powered electricity generation trestle component, for producing in enormous quantities, is welding blank, requires processing 8 holes, overturn 90 ° of another 6 holes of needs in front.Traditional handicraft is processed on CNC milling machine, and need twice installation to clamp, twice tool setting, production efficiency is on the low side.Producing non-cutting time for reducing, comprising tool setting, hand-operated clamping time, manual tool changing time.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to reality need, designs a kind of automatic overturning clamping apparatus.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of automatic overturning clamping apparatus, comprise base plate, longitudinal holder is provided with in the middle part of described base plate, described holder comprises the support nail of vertical direction setting and the depression bar of horizontal direction, one end of described depression bar is driven by external force does vertical motion, the other end is positioned at the top in the middle part of base plate, and described base plate drives upset by hydraulic swivel.
Described holder also comprises spacing rest pad, and described spacing rest pad is positioned at bottom edge.
The piston rod of one end of described depression bar and corner hydraulic cylinder or swing clamp cylinder is connected and is driven by it and does vertical motion.
The piston rod of described corner hydraulic cylinder or swing clamp cylinder rotates around its axis.
Described corner hydraulic cylinder is provided with two and is symmetricly set in the two ends of base plate.
Described support nail comprises two or more, and the peak of each support nail is all positioned at same level.
Described spacing rest pad comprises lateral support block and longitudinal supporting block, and each supporting is distributed in outside holder.
The beneficial effects of the utility model are:
1. reduce when this part is produced trade union college time, tool setting time and hand-operated clamping time;
2. enhance productivity, reduce labour intensity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is base plate, and 2 is hydraulic swivel, and 3 is corner hydraulic cylinder, and 4 is spacing rest pad, and 5 is support nail, and 6 is depression bar, and 7 is holder.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: see Fig. 1.
The utility model discloses a kind of automatic overturning clamping apparatus, comprise base plate 1, longitudinal holder is provided with in the middle part of described base plate 1, described holder comprises the support nail 5 of vertical direction setting and the pressure 6 of horizontal direction, one end of described depression bar is driven by external force does vertical motion, the other end is positioned at the top in the middle part of base plate 1, and described base plate 1 drives upset by hydraulic swivel 2.The piston rod of one end of described depression bar 6 and corner hydraulic cylinder 3 or swing clamp cylinder is connected and is driven by it and does vertical motion.The piston rod of described corner hydraulic cylinder 3 or swing clamp cylinder rotates around its axis.Described corner hydraulic cylinder 3 is provided with two and is symmetricly set in the two ends of base plate 1.Described support nail 5 comprises two or more, and the peak of each support nail 5 is all positioned at same level.Described spacing rest pad 4 comprises lateral support block and longitudinal supporting block, and each supporting is distributed in outside holder.
Original state, the outside of depression bar 6 free end deflection chassis 1, is placed on holder 7 on support nail 5, and then corner hydraulic cylinder 3 piston rod drives depression bar 6 to turn to the top of holder 7, then drives depression bar 6 to be clamped by holder 7 downwards.Preferably, holder also comprises spacing rest pad 4, and described spacing rest pad 4 is positioned at base plate 1 edge, spacing rest pad 4 is arranged at the outside of holder 7, can plays the effect of auxiliary stopper.After clamping, can process the exposed surface of holder 7.After completion of processing, drive base plate 1 to overturn by hydraulic swivel 2, holder 7 can be turned, another one face is processed.
Holder 7 in the utility model adopts bottom surface, two sides as positioning reference plane, by support nail 5 limit feature three degree of freedom, the spacing rest pad 4 of long side surface two limits two free degree, the spacing rest pad 4 that another side is arranged limits workpiece one degree of freedom, can realize the location to specific holder; Described corner hydraulic cylinder 3, is distributed in holder both sides, after holder is had good positioning, can control pressure arm and rotate to above part, then rectilinear motion can by Workpiece clamping vertically downward by the reversal valve controlled on described corner hydraulic cylinder 3.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
