Description

Technical Field

[0001] The utility model belongs to the technical field of flange processing, in particular to a flange processing fixture. Background Art

[0002] Flange is also called flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as reducer flange. Flange connection or flange joint refers to a detachable connection that is connected by flange, gasket and bolts as a combined sealing structure.

[0003] During the flange processing, it is necessary to perform micro-processing on the surfaces of both sides, so the flange needs to be clamped. However, most of the existing clamps are single-group settings. Although the flange can be clamped, the work efficiency is relatively low. At the same time, it is difficult to flip the flange as needed to facilitate subsequent processing on both sides, which reduces the scope of application of the clamp. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the utility model provides a flange processing fixture, which can effectively solve the problems of the prior art.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

The driving rack is evenly arranged in a ring shape on the lower end surface of the base body. The driving gear is rotatably connected to one side of the lower end surface of the driving rack. The servo motor is fixed at one end of the driving gear, and the lower end of the servo motor is connected to the base body.

[0012] Furthermore, a connecting piece is fixed on the outer surface of the adjustment frame, and the cross section of the connecting piece is an "L"-shaped structure.

[0013] Furthermore, the flipping mechanism includes a second driving rack and a connecting gear, wherein the second driving rack is evenly fixed on the upper end surface of the driving plate in a ring shape, the connecting gear is meshedly connected to the upper end of the second driving rack, and the connecting gear is fixed on the outer surface of the connecting shaft.

[0014] Furthermore, the clamping assembly includes a limiting slide groove, a clamping ring, a limiting slide rod and a driving motor group. The limiting slide groove is symmetrically opened at the upper and lower ends of the clamping member, and the cross-section of the limiting slide groove is a "T"-shaped structure. The clamping ring is slidably clamped in the limiting slide groove, the limiting slide rod is fixed on the lower end surface of the clamping ring and slides left and right along the limiting slide groove.

[0017] The utility model has the following beneficial effects:

[0018] The utility model can adjust the angle of the adjustment frame by setting an angle adjustment mechanism. When the clamping member processes one group of flanges, it will not affect the clamping of another group of clamping members, thereby further improving the working efficiency of the clamp. Then, the set flipping mechanism can drive the connecting shaft to rotate at multiple angles, and the clamping member can be flipped according to its own needs, and manual flipping of the clamping member can be avoided. Not only can the safety during the construction process be reduced, but also the processing efficiency of the flange can be guaranteed, and the application scope of the equipment can be further improved. At the same time, the set clamping assembly can clamp the flange to facilitate subsequent micro-processing of the flange surface. BRIEF DESCRIPTION OF THE DRAWINGS

The drive adjustment 7 can drive the drive plate 8 to rotate, and the drive plate 8 The driving rack 2 9 at the end can mesh with the connecting gear 10, and can drive the connecting shaft 11 to rotate. Since the connecting shaft 11 is provided with three groups, when the driving plate 8 rotates 120°, the connecting gear 10 can just be turned over 180°, and then the clamping member 13 can be turned over. The outer surface of the connecting shaft 11 is set with a limiting base 12, and the limiting base 12 is connected to the inner wall of the adjustment frame 2 by bolts.
