Problems solved by technology

The manufacturing cost of special fixtures or molds is very high, and the most fatal problem is that a fixture can only be applied to a certain type of parts or a specific processing technology
When the surface features or dimensions of the part change, it is likely that the original fixture cannot be used, and it is necessary to redesign and develop a special fixture or mold

Embodiment Construction

[0026] Such as figure 1 As shown, the present invention is composed of upper and lower sets of clamp bodies arranged symmetrically. The uppermost and lowermost ends are two "well"-shaped frame bodies 10, and there are through holes at the eight end points of the "well" shape, with handles The long-leg screw rod 2 of 1 runs through and connects the upper and lower frame bodies 10, and is fixed with fastening nuts 18. All have threaded mouth in the middle part of four limits of " well " font frame body 10 up and down, the supporting adjustable screw rod 20 of four band size scales is equipped with, and the adjustable screw rod 20 outer ends of supporting have adjustment handle 19. In the upper clamping body, the four supporting adjustable screw rods 20 are respectively covered with springs 9 . Have threaded hole to screw into screw rod 8 respectively at the center of " well " shape frame body 10 , one end of screw rod 8 is connected with ball nut 6 and screw handle 7 , and the ...

Abstract

A flexible apparatus for locating and clamping a thin-wall workpiece with 3D shaped surface at multiple points is composed of two rectangular frames linked by scrwe bolts and with the regulating screws on their four sides, 4 lines X6 columns elastic sleeve tubes arranged uniformly on the netted structure in said frame and two barrier plates parallel in said frames and with regulating screws, locating pins and 4 locking tensional plates.

Description

technical field [0001] The invention relates to a positioning and clamping device, in particular to a flexible device for multi-point positioning and clamping of three-dimensional thin-walled parts in space. Edge, drilling and milling, stamping grinding, welding assembly, wire cutting, surveying and marking, etc. machinery manufacturing fields. Background technique [0002] With the development trend of lightweight product structure and beautiful appearance, more and more thin-walled parts with complex three-dimensional profiles appear in production, and the positioning and clamping of such parts are generally considered to be a difficult point. This is because, on the one hand, it is required that the positioning surface of the fixture can closely fit the complex curved surface of the part to achieve accurate positioning. On the other hand, it is required that the fixture can provide reliable clamping force without causing excessive deformation of the part, or Even damage ...
