Purpose of the present invention can also further realize by following technical measures.
Aforesaid thin-wall curved-surface part assembling and positioning anchor clamps, wherein said positioning sucker disk seat upper surface is provided with notch for one jiao, and three faces that intersect vertically that constitute notch form three planes, location.
Aforesaid thin-wall curved-surface part assembling and positioning anchor clamps, adjacent dual-side shape that wherein said sucker disk seat is relative with described notch and thin-wall curved-surface part edge shape are coincide.
The present invention is adsorbed on separately thin-wall curved-surface piece surface by pull of vacuum with positioning sucker disk seat, and it is fixedly connected mutually by the orientation angle iron phase, thereby realize the assembling of polylith thin-wall curved-surface part, simple in structure, absorption affinity is strong, and clamping is reliable and stable, easy to operate, the positioning sucker disk seat upper surface is provided with three planes, location, location when being convenient to assemble and measurement, positioning accuracy height.
Advantage of the present invention and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a perspective view of the present invention;
Fig. 2 is that the A of Fig. 1 is to perspective view;
Fig. 3 is the perspective view of analysing and observe of positioning sucker disk seat of the present invention;
Fig. 4 utilizes the present invention to assemble the perspective view of thin-wall curved-surface part.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As Fig. 1～shown in Figure 3, the present invention includes positioning sucker disk seat 1, sealing strip 2, vacuumize piston rod 3, sealing ring 4 and 2 location angle bar 5, positioning sucker disk seat 1 bottom surface is a curved surface, positioning sucker disk seat 1 bottom surface curvature is identical with thin-wall curved-surface part 6 curvature, being convenient to the two fits well, strengthen absorption affinity, positioning sucker disk seat 1 is absorbed and fixed at thin-wall curved-surface part 6 surfaces, its upper surface is provided with notch 11 for one jiao, three faces that intersect vertically that constitute notch 11 form three planes 111, location, 112 and 113, location when being convenient to assemble and measurement, positioning sucker disk seat 1 and notch 11 relative adjacent dual- sides 12 and 13 are curved surface, its shape and thin-wall curved-surface part 6 edge shapes coincide, easy to assembly, sealing strip 2 is inlaid on positioning sucker disk seat 1 bottom surface, sealing strip 2 contacts with thin-wall curved-surface part 6 surfaces during assembling, seal, vacuumizing piston rod 3 is arranged in the through hole 14 at positioning sucker disk seat 1 middle part, vacuumizing piston rod 3 upper ends is threaded with through hole 14 upper ends, the vacuum chamber 15 of 14 ends slidably is connected under its lower end and the through hole, can slide up and down along the vacuum chamber 15 of through hole 14 lower ends, sealing ring 4 is inlaid in and vacuumizes piston rod 3 lower ends, and contact with the vacuum chamber 15 of through hole 14 lower ends, thin-wall curved-surface part 6 surfaces like this, sealing strip 2, form a confined space between the vacuum chamber 15 of through hole 14 lower ends and the sealing ring 4, the volume of the vacuum of confined space and confined space initial residual gas is inversely proportional to, be directly proportional with the displacement that vacuumizes piston rod 3,2 location angle bar 5 are separately positioned on positioning sucker disk seat 1 both sides, be used for adjacent positioned sucker disk seat 1 fixedly connected, thereby polylith thin-wall curved-surface part 6 is fixedly connected.
