[0028] Please refer to FIG. 1 to FIG. 2, a quick and reliable elbow clamping positioning module, comprising a box body 1 and a clamping assembly 2 connected with the box body 1. Wherein, the box body 1 comprises a left side plate 11, a right side plate 12 and a bottom plate 13 connecting the left side plate 11 and the right side plate 12, the clamping assembly 2 is provided with two groups, two groups of clamping assembly 2 are connected on the side of left side plate 11 and right side plate 12 facing each other, and the clamping space 3 is formed between the two groups of clamping assembly 2, the elbow 4 to be processed is placed in the clamping space 3, so as to facilitate the hoisting, transportation, polishing, storage, assembly, welding and other processes of the elbow 4 to be processed by moving or fixing the box body 1.

[0029] In the prior art, the connection between the clamping assembly 2 and the left side plate 11 and the right side plate 12 is fixed, so that different types of clamping assembly 2 need to be configured correspondingly when clamping different types and sizes of elbows, which is high in module cost and complicated in replacement process, and is not conducive to the automation of the whole processing flow.

[0030] In order to solve the above problems existing in the prior art, in the present embodiment, the two groups of clamping assembly 2 can move in the direction of approaching or moving away from each other under the driving of external force, so as to clamp or release the elbow 4 to be processed, and the size of the clamping space 3 between the two groups of clamping assembly 2 can also be changed, which can clamp more accurately and firmly, and can also adapt to different types and sizes of elbows 4 to be processed, so as to reduce the module cost, and the adjustment process is also convenient, which is convenient for automation implementation, and when the elbow 4 to be processed is clamped by the clamping assembly 2, the two ends of the elbow 4 to be processed protrude out of the box body 1, which is convenient for processing the two ends of the elbow 4 to be processed.

[0031] Specifically, the middle part of the left side plate 11 and the right side plate 12 has a threaded hole 14, the clamping assembly 2 includes a threaded pressing disc 21 screwed with the threaded hole 14 of the left side plate 11 and / or the right side plate 12, an arc-shaped pressing plate 22 connected with the elbow 4 to be processed, and a force transmission plate component 23 connecting the threaded pressing disc 21 and the arc-shaped pressing plate 22. In this embodiment, the threaded pressing disc 21 is tightened by using a special wrench, and the arc-shaped pressing plate 22 is driven by the force transmission plate component 23 to move towards or away from the elbow 4 to be processed, so as to adjust the size of the clamping space 3.

[0032] In this embodiment, the middle part of the left side plate 11 and the right side plate 12 is connected with the threaded pressing disc 21 of the clamping assembly 2, and the adjustment accuracy and flexibility are further improved by adjusting the two sets of clamping assemblies 2, while ensuring that the elbow 4 to be processed can be kept centered in the module, facilitating the operation of the subsequent process.

[0033] The side of the arc-shaped pressing plate 22 facing the elbow 4 to be processed is recessed inward to form an arc surface 221, and the arc surface 221 abuts against the outer wall 41 of the elbow to be processed when the clamping assembly 2 clamps the elbow to be processed, so that the clamping effect of the clamping assembly 2 is more firm. The force transmission plate component 23 includes a square force transmission hard plate (not shown) connected with the threaded pressing disc 21 and a square force transmission soft plate connecting the square force transmission hard plate (not shown) and the arc-shaped pressing plate 22. The arc-shaped pressing plate 22 is a whole curved plate with an arc, and the curvature and the arc are consistent with the elbow 4 to be processed, so as to ensure the close fit with the elbow 4 to be processed. The arc-shaped clamping plate can be made of soft materials such as PU (polyurethane) and rubber plate, or hard materials such as steel plate and nylon. Whether the arc-shaped clamping plate is made of hard or soft material depends on the material of the front force transmission plate component 23. If the force transmission plate component 23 is made of hard material, the arc-shaped clamping plate is made of soft material, and vice versa.

[0034] In the above embodiment, the material of the square force transmission hard plate can be steel or nylon, the material of the square force transmission soft plate can be PU (polyurethane) or rubber plate, and the material of the box body 1 is steel.

[0035] It is worth noting that the box body 1 further includes a back plate 15 connected with the left side plate 11, the right side plate 12 and the bottom plate 13 respectively. The back plate 15 is formed with a stop 151 and a plurality of screw holes 152, and the box body 1 further includes a chuck clamping tail pipe 16 connected with the stop 151 and the screw holes 152. The elbow clamping and positioning module can be clamped by an external chuck through the chuck clamping tail pipe 16, thereby realizing automatic processing.

[0036] In order to prevent the elbow 4 to be machined clamped by the clamping assembly 2 from falling, in the embodiment, the left side plate 11 and the right side plate 12 have a U-shaped groove 17 at the top of the side away from the back plate 15, and the elbow clamping and positioning module further comprises a quick-mounting positioning connecting rod component 5, both ends of the quick-mounting positioning connecting rod component 5 are fixedly connected in the U-shaped groove 17. Wherein, the quick-mounting positioning connecting rod component 5 comprises a positioning rod 51 and a fixing piece 52, both ends of the positioning rod 51 have positioning holes (not shown), and the fixing piece 52 is fixed in the positioning holes through the U-shaped groove 17 to fixedly connect between the left side plate 11 and the right side plate 12, so that the elbow 4 to be machined is firmly limited in the module by the limiting effect of the fixing piece 52, and falling is prevented. The fixing piece 52 is a screw rod, and the positioning hole is a corresponding screw hole 152.

[0037] As described above, the left side plate 11, the right side plate 12, the bottom plate 13 and the back plate 15 of the module are all provided with the weight-reducing holes 6, so as to reduce the weight of the whole module and facilitate carrying and moving.

[0038] In order to facilitate hoisting of the module, the hoisting rings 7 are arranged at the top of both sides of the left side plate 11 and the right side plate 12, and when the module needs to be hoisted, only the hoisting rings 7 need to be tightly bound by the hoisting ropes, which is quick and convenient.

When the elbow to be machined is clamped by the clamping assembly, both ends of the elbow to be machined protrude out of the box body, which facilitates machining and processing of both ends of the elbow to be machined.

[0040] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, those skilled in the art can make other different forms of changes or modifications without creative labor, which should all belong to the protection scope of the present application.
