Description

Technical Field

[0001] The utility model belongs to the technical field of detection tooling, and more specifically, particularly relates to a flange detection tooling. Background Art

[0002] The flange neck is annular and located on the end face of the flange. The top of the flange neck is provided with an annular plane, an annular outer slope, and an annular inner slope. The annular plane is located between the outer slope and the inner slope, and the two sides of the annular plane are respectively connected to the top of the outer slope and the inner slope. The sizes of the annular plane, the outer slope, and the inner slope at the top of the flange neck are usually detected by using a card to clamp on the top of the flange neck.

[0003] The utility model with application number 202021559860.6 discloses a flange neck detection tool, including: a horizontal ruler, a vertical ruler, a first swing arm, a second swing arm, and a movable vertical ruler. The outer end of the horizontal ruler and the top end of the vertical ruler are fixed vertically to each other, and a scale is provided on the lower edge of the horizontal ruler, and a scale is also provided on the vertical edge on the inner side of the vertical ruler. A guide long hole is also provided on the horizontal ruler. The upper ends of the first swing arm, the second swing arm, and the movable vertical ruler are all hinged to the horizontal ruler, and the hinge axes of the first swing arm, the second swing arm, and the movable vertical ruler are all located in the guide long hole, and a scale is also provided on the vertical edge on the outer side of the movable vertical ruler. The above-mentioned flange neck detection tool can detect flange necks of different sizes because the movable vertical ruler on it can move inward and outward, the first swing arm can move inward and outward and can also swing, and the second swing arm can move inward and outward and can also swing, thereby reducing the detection cost and improving the detection efficiency.

[0004] Based on the search of the above patents and the understanding of the existing flange detection applications: Most of the current flange detection is simply to detect a single position of the flange, and subsequent replacement of other detection tools must be replaced for detection, which is rather cumbersome.

At the same time, the length of the flange workpiece is determined in combination with the scale value of the measuring seat.

[0014] After the flange workpiece is fixed, the screw rod is rotated to drive the slider to slide forward until the L-shaped positions above the two positioning and measuring plates are in contact with the rear end of the flange workpiece. Next, the bidirectional screw rod is rotated to drive the two positioning and measuring plates to move closer to each other. The two positioning and measuring plates clamp and fix the two sides of the rear end of the flange workpiece.
