Problems solved by technology

[0002] There is an existing flange, which is provided with reinforcing ribs for its strength, so the bolt connection holes need to be arranged between the reinforcing ribs, and it needs to be accurately positioned; the existing clamping and positioning method is, on the flange Scribe a line, and cut off a part of the flange through the scribed line, so that the flange forms an incomplete circle, thereby forming a positioning plane, and then cooperate with the outer circumference of the flange plate through the V-shaped positioning fork, and pass a The positioning block with a plane cooperates with the positioning plane on the flange to realize the clamping of the flange, and the positioning of the flange is realized through the cooperation of the positioning block and the positioning plane; although this method realizes the positioning of the flange The clamping and positioning of the disc, but it is necessary to cut the flange, which increases the processing procedure and prolongs the processing time, and also damages the structure of the flange after cutting the flange.

Embodiment 1

[0017] The embodiment is basically as attached figure 1 , figure 2 Shown: A clamping and positioning device for a flange includes a clamping seat 1, a clamping jaw 2, a compression bolt 3 and a return spring 4; the clamping base 1 is a square shell, and there are two clamping jaws 2 , and are symmetrically hinged in the inner cavity of the clamping seat 1, one end of the jaw 2 is the clamping end 21, and the other end is the force end 22, the clamping end 21 has a circular arc-shaped clamping surface 211, and the clamping The surface 211 has the same radian as the periphery of the flange 5 to be clamped, the clamping surface 211 is perpendicular to the force end 22, and there is an arc-shaped protrusion 212 on the left side of the clamping surface 211. There is a limit notch 214 on the protrusion 212, and the two opposite sides of the limit notch 214 have a certain slope; the compression bolt 3 is screwed on the clamping seat 1, located on the right side of the jaw 2, and ex...

Embodiment 2

[0020] as attached image 3 As shown, the difference between the second embodiment and the first embodiment is that the limit block 11 is canceled in the second embodiment, and the limit arc surface 213 is set on the right side of the clamping surface 211 of the jaw 2, and the limit arc The surface 213 is an arc surface with the same radian as the clamping surface 211, the limiting arc surface 213 forms an included angle of 150o with the clamping surface 211, and the limiting arc surface 213 protrudes outward relative to the clamping surface 211, limiting The distance from the intersection line between the arc-shaped surface 213 and the clamping surface 211 to the intersection line between the arc-shaped protrusion 212 and the clamping surface 211 is equal to the thickness of the flange 5 .

[0021] During the clamping process, the two limit arc surfaces 213 also rotate toward the center at the same time, but due to the inclination between the limit arc surfaces 213 and the cl...

Abstract

The invention discloses a clamping and positioning device for a flange and relates to a flange clamp. The clamping and positioning device for the flange comprises a clamping seat, clamping jaws and pressing bolts. The clamping seat is provided with a clamping seat inner cavity, and the two clamping jaws are symmetrically hinged to the clamping seat inner cavity. One ends of the clamping jaws are clamping ends, and the other ends of the clamping jaws are stress ends. The clamping ends are provided with circular-arc-shaped clamping faces. The clamping faces are perpendicular to the stress ends. A circular-arc-shaped protrusion is arranged on the clamping face of the front end of each clamping jaw, and a limiting notch is formed in each circular-arc-shaped protrusion. The pressing bolts are screwed on the clamping seat and located on the rear sides of the clamping jaws, stretch into the clamping seat inner cavity and abut against the stress ends of the clamping jaws. A rear limiting part is further arranged on the rear side of each clamping jaw. According to the clamping and positioning device for the flange, machining processes in the flange machining process can be reduced, and positioning and clamping of the flange can be achieved rapidly.
