A kind of quick positioning compression device of flip-over type automatically
the utility model relates to a kind of hold down gag, is specifically related to a kind of quick positioning compression device of flip-over type automatically.
car body workpiece, in the time that machine adds production, for guaranteeing that its geomery is controlled within the scope of designing requirement, need to be controlled with reliable clamping tool.Original clamp effect, reliability and flexibility have much room for improvement.Chinese patent CN201120106638.5 discloses a kind of screw welding apparatus, comprise base, U-shaped bearing, straight pin, leg, location-plate and spring attachment, leg is fixed on the below of base, U-shaped bearing is located by connecting on base, straight pin is located by connecting on base, location-plate and spring attachment are fixed on base, use this screw welding apparatus, can make screw rod and support be difficult in welding process loosening, after welding, the perpendicularity of screw rod and support can guarantee, has saved cost, has improved effect.But its scope of application is comparatively narrow, can not be widely used in the clamping processing of all kinds of car body workpiece.
Utility model content
the utility model object is to overcome above-mentioned deficiency, and a kind of quick positioning compression device of flip-over type is automatically provided, and it not only can carry out quick-replaceable according to the shape regioselective plate of workpiece, improves work efficiency, and accurate positioning, and repeatable accuracy is high.
the utility model is achieved through the following technical solutions utility model object: a kind of quick positioning compression device of flip-over type automatically, comprise dual-purpose pressure head, screw rod, spring, base plate, baffle plate and arm-tie, described base plate is fixedly connected with rotating shaft, in described rotating shaft, cover has dual-purpose pressure head, between described dual-purpose pressure head and base plate, be provided with spring, location-plate is equipped with respectively in described dual-purpose pressure head both sides, and described location-plate and dual-purpose pressure head removably connect.
further, described rotating shaft and base plate are fastening by screw and spring washer.
further, described base plate is also connected with baffle plate by holding screw.
further, described base plate below is also provided with arm-tie, and described arm-tie and base plate are fixed by screw and frock.
the utility model compared with prior art, has following good effect: the repetition accuracy of this fixture is guaranteed by spring, turn screw rod, and under spring action, screw rod can drive the reposition leggiero of dual-purpose pressure head.The utility model has the advantages that reliability is high, clamp effectively, repeatable accuracy is high.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.Wherein, 1. dual-purpose pressure head; 2. packing ring; 3. screw rod; 4. location-plate; 5. screw; 6. spring washer; 7. arm-tie; 8. screw; 9. baffle plate; 10. holding screw; 11. base plates; 12. rotating shafts; 13. springs.
the specific embodiment
below with reference to the accompanying drawings shown in, in conjunction with example, the utility model is described further.
embodiment 1: a kind of quick positioning compression device of flip-over type automatically, dual-purpose pressure head 1 and rotating shaft 12 coordinate, and control spacingly by spring 13, screw rod 3 and packing ring 2, and rotating shaft 12 and base plate 11 are fixing by screw 5, spring washer 6 and holding screw 10.Arm-tie 7 and base plate 11 are fixed by screw 8 and frock, and base plate 11 is connected by holding screw 10 with baffle plate 9, and rotating shaft 12 and base plate 11 are fastening by screw 5 and spring washer 6.Screw rod 3 and packing ring 2 coordinate with rotating shaft 12.Dual-purpose pressure head 1 is enclosed within rotating shaft 12 according to dimensional requirement.According to clamping machinable workpiece, select applicable location-plate 4.By on-site verification, use this measurer can be easy, clamping work pieces fast and accurately, improved operating efficiency.
the improvement that the utility model carries out mainly for the quick positioning compression device of a kind of automatic flip-over type, the foregoing is only the utility model preferred embodiment, non-ly therefore limit to the scope of the claims of the present utility model, therefore simple and easy variation and the equivalent transformation of such as doing by the utility model description and graphic content, all should be contained in the scope of the claims of the present utility model.
