Description

Technical Field

[0001] The utility model relates to the technical field of flange clamping tooling, in particular to a graduated clamping tooling for a metal flange. Background Art

[0002] Flange is also called flange or flange. Flange is a part that connects pipes to pipes and valves, and is connected to the pipe end. There are holes on the flange, and bolts connect the two flanges tightly. Gaskets are used to seal the flanges. Flanges are divided into threaded (threaded) flanges, welding flanges and ferrule flanges. During the flange drilling or reaming process, it is necessary to process the center axis of the flange to be processed, but the existing equipment requires manual support of the flange to be processed during the processing. Those skilled in the art will design special tooling according to actual conditions, such as the disclosed patent CN202321436274.6 hydraulic flange joint base indexing drilling tooling, which can solve the problem of indexing drilling very well. Another solution is to clamp it externally. Therefore, a indexing clamping tooling is proposed. Utility Model Content

DETAILED DESCRIPTION

[0015] The present invention will be described below based on the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. However, it is worth noting that the present invention is not limited to these embodiments. In the detailed description of the present invention below, some specific details are described in detail. However, for the parts that are not described in detail, those skilled in the art can also fully understand the present invention.

[0016] In addition, those skilled in the art should understand that the drawings are only provided to illustrate the purpose, features and advantages of the present invention, and the drawings are not actually drawn according to scale.

[0017] At the same time, unless the context clearly requires otherwise, the words "include", "comprises" and similar words throughout the specification and claims should be interpreted as inclusive rather than exclusive or exhaustive; that is, the meaning is "including but not limited to".

[0018] See also Figure 1-Figure 6 The utility model provides a technical solution: comprising a support plate 1, the support plate 1 is provided with a swivel seat 2 and a positioning mechanism 3, a turntable 4 is provided above the swivel seat 2, a clamping mechanism 5 is provided above the turntable 4, the positioning mechanism 3 comprises a positioning support 301 and a positioning handle 302; the clamping mechanism 5 comprises a clamping support 501, a clamping claw 502, a lifting frame 503, a guide column 504 and a nut 505.
