AI Technical Summary
Existing elbow processing fixtures cannot move synchronously on both sides when clamping elbows, making it difficult to clamp both ends of the elbow at the same time and affecting processing efficiency.
A bending head processing fixture was designed, which includes a rotating shaft, a turntable, a clamping mechanism, a linkage mechanism, and a fixing mechanism. The linkage mechanism enables the two clamping plates to move synchronously, thereby achieving synchronous clamping and fixing of the bending head.
It achieves synchronous clamping at both ends of the elbow, improving processing efficiency and control accuracy of the center position.

Technical Field
[0001] This utility model relates to a fixture for processing elbows. Background Technology
[0002] Elbows can be used for discharge pipelines, inlet pipelines, temporary fluid flow pipelines, well test pipelines, and other working environments for conveying fluid flow. During the processing of elbows, threads need to be machined at both ends of a bend. Currently, when machining the threads at both ends of an elbow, it needs to be clamped. When clamping the elbow, the clamps on both sides need to be adjusted separately, which means that the clamps on both sides of the elbow cannot move synchronously to clamp the elbow.

Its structural features are: it also includes a clamping mechanism, a linkage mechanism, and a fixing mechanism. The clamping mechanism and the fixing mechanism are both set on the turntable. One end of the linkage mechanism is connected to the clamping mechanism, and the other end of the linkage mechanism is connected to the fixing mechanism. The clamping mechanism includes a clamping plate, a clamping slider, and a clamping groove. The clamping plate and the clamping slider are fixed. The clamping groove is set on the turntable, and the clamping slider is located in the clamping groove.
[0005] Furthermore, the linkage mechanism includes a linkage body, a linkage groove, and a linkage shaft. The linkage shaft is fixed on the clamping slider, one end of the linkage body is hinged to the linkage shaft, and the linkage groove is provided at the other end of the linkage body.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0017] Example
[0018] See Figures 1 to 3 As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.
[0019] The elbow processing fixture in this embodiment includes a rotating shaft 1, a turntable 2, a clamping mechanism 3, a linkage mechanism 4, and a fixing mechanism 5. The rotating shaft 1 is fixed to the turntable 2. The clamping mechanism 3 and the fixing mechanism 5 are both set on the turntable 2. One end of the linkage mechanism 4 is connected to the clamping mechanism 3, and the other end of the linkage mechanism 4 is connected to the fixing mechanism 5. The rotating shaft 1 is mounted on the chuck of the lathe.

The clamping plate 31 is fixed to the clamping slider 32, the clamping groove 33 is disposed on the turntable 2, and the clamping slider 32 is located in the clamping groove 33.
[0021] The linkage mechanism 4 in this embodiment includes a linkage body 41, a linkage groove 42, and a linkage shaft 43. The linkage shaft 43 is fixed on the clamping slider 32. One end of the linkage body 41 is hinged to the linkage shaft 43, and the linkage groove 42 is provided at the other end of the linkage body 41.
[0022] The fixing mechanism 5 in this embodiment includes a fixing seat 51, a fixing groove 52, a fixing slider 53, a fixing shaft 54, and a fixing nut 55. The fixing seat 51 is disposed on the turntable 2, the fixing groove 52 is disposed on the fixing seat 51, the fixing slider 53 is fixed to the fixing shaft 54, the fixing slider 53 is located in the fixing groove 52, the fixing shaft 54 is located in the connecting rod groove 42, and the fixing nut 55 is disposed on the fixing shaft 54 and contacts the connecting rod body 41.
[0023] Specifically, when using this elbow processing fixture, the fixing nut 55 can be loosened to disengage it from the connecting rod body 41.
