[0032] like Figure 1-4 As shown, this utility model provides a technical solution: a coaxial tube bending angle positioning device, including a base 1, an abutment device 2 and a locking device 3.

[0033] Reference Figure 1 The base 1 includes a mounting base 11. In this embodiment, the mounting base 11 is preferably a rectangular strip. The mounting base 11 is vertically arranged and can fit against the side wall of the external structure. The mounting base 11 is provided with a mounting groove 12 through it, parallel to the side wall of the external structure. The opening direction of the mounting groove 12 is perpendicular to the side wall of the external structure, and the long side direction of the mounting groove 12 is parallel to the long side direction of the mounting base 11.

[0034] Reference Figure 1 The base 1 also includes two positioning bolts 13, which are arranged sequentially along the long side of the mounting groove 12, and the positioning bolts 13 are threaded to the external structure after passing through the mounting groove 12.

[0035] Operators can use positioning bolts 13 to fix the base 1 to the corresponding position on the external structure.

[0036] Reference Figure 1 The end face of the mounting base 11 away from the external structure is provided with a groove 14. In this embodiment, the long side of the groove 14 is parallel to the long side of the mounting base 11. The inner cavity of the groove 14 is provided with a slider, which can slide along the long side of the groove 14. The slider is provided with a mounting plate 15 and a mounting block 16. The mounting plate 15 is rotatably connected to the slider by a bearing connection, and the rotation axis of the mounting plate 15 is perpendicular to the plane of the mounting base 11. The mounting plate 15 is provided with a set screw 17, which passes through the mounting plate 15 and abuts against the surface of the mounting base 11. The set screw 17 and the mounting plate 15 are threadedly connected. The mounting block 16 is fixedly connected to the mounting plate 15 by welding.

[0037] The operator can adjust the position of the mounting plate 15 by sliding the slider, and fix the angle of the mounting block 16 by using the set screw 17.

[0038] Reference Figure 1 In this embodiment, the mounting block 16 is preferably a rectangular block, and the mounting block 16 is provided with a through hole 18.

[0039] Reference Figure 1 The abutment device 2 includes a mounting rod 21, an abutment plate 22, and a first spring 23. In this embodiment, the mounting rod 21 is preferably a circular rod. The outer wall of the mounting rod 21 is attached to the through hole 18 and can slide along the axial direction of the through hole 18. The end of the mounting rod 21 can abut against the hole of the workpiece to position the workpiece. A positioning ring 221 is coaxially fixedly connected to the end of the mounting rod 21 near the workpiece. The radius of the positioning ring 221 is larger than the radius of the through hole 18. The abutment plate 22 is fixed to the end of the mounting rod 21 away from the workpiece by welding. The abutment plate 22 and the mounting rod 21 are coaxially arranged. The first spring 23 is sleeved on the mounting rod 21 and is located between the abutment plate 22 and the mounting block 16. The first spring 23 can slide along the axial direction of the mounting rod 21. The two ends of the first spring 23 abut against the end faces of the mounting block 16 and the abutment plate 22 that are close to each other.

[0040] The operator can press the abutment plate 22 to make the mounting rod 21 abut against the corresponding position of the workpiece, thereby completing the positioning of the workpiece. The setting of the first spring 23 can avoid excessive contact between the mounting rod 21 and the workpiece, which may affect the workpiece.

[0041] Reference Figure 1 and Figure 2The mounting rod 21 is coaxially provided with a positioning groove 24 at one end away from the mounting block 16. The mounting rod 21 is provided with multiple guide grooves 25 on the side wall of the positioning groove 24. The long side direction of the guide groove 25 is consistent with the axial direction of the mounting rod 21. The multiple guide grooves 25 are evenly distributed circumferentially along the axial direction of the positioning groove 24. The inner cavity of the guide groove 25 is provided with a second spring 26 and a guide block 27. The guide block 27 can slide along the long side direction of the guide groove 25. The two ends of the second spring 26 are fixedly connected to the mounting rod 21 and the guide block 27, respectively.

[0042] Reference Figure 1 and Figure 2 Each guide block 27 is equipped with an abutting component 28. In this embodiment, the abutting component 28 includes a support rod 281 and an abutting block 282. The support rod 281 is preferably an arc-shaped rod. The long side of the support rod 281 is parallel to the long side of the mounting rod 21. The support rod 281 can slide along the long side of the mounting rod 21. The abutting block 282 is preferably a conical block, and multiple conical blocks together form a complete cone.

[0043] Reference Figure 1 The end of the abutment block 282 away from the mounting rod 21 is set as a plane, and the plane is perpendicular to the axial direction of the mounting rod 21.

[0044] Reference Figure 1 The outer wall of the abutment block 282 is fitted with a friction pad, and the friction pad is fixedly connected to the abutment block 282 by screws.

[0045] The positioning groove 24 limits the sliding direction of the abutment component 28. At the same time, multiple abutment blocks 282 form a complete cone, which can limit the hole positions of different diameters of the workpiece and improve the overall applicability of the device.

[0046] Reference Figure 1 , Figure 3 and Figure 4 The mounting block 16 has a locking device 3 on its side wall. The locking device 3 includes a fixing rod 31 and a positioning plate 32. The fixing rod 31 is rotatably connected to the mounting block 16 by a torsion spring. The rotation axis of the fixing rod 31 is parallel to the end face of the mounting block 16. The end face of the fixing rod 31 near the abutment plate 22 has a fixing groove 33. The fixing rod 31 has a sliding groove 34 on the side wall of the mounting groove 12. In this embodiment, the sliding groove 34 is preferably an arc-shaped groove. The inner cavity of the arc-shaped groove has a sliding block 35 and a third spring 36. The sliding block 35 can slide along the long side of the sliding groove 34. The two ends of the third spring 36 are fixedly connected to the sliding block 35 and the fixing rod 31, respectively. The positioning plate 32 passes through the fixing groove 33 and extends to one side of the abutment plate 22. The positioning plate 32 is fixedly connected to the sliding block 35 by screws.

[0047] Reference Figure 1 , Figure 3 and Figure 4 The end face of the positioning plate 32 away from the mounting block 16 is set as an inclined surface, wherein the inclined direction of the positioning plate 32 is from the axis of the fixing rod 31 to the mounting rod 21, and is inclined towards the abutment block 282.

[0048] Reference Figure 1 , Figure 3 and Figure 4 The positioning plate 32 has an adjustment groove 37 on its end face near the mounting block 16. An adjustment bolt 38 and an adjustment plate 39 are located in the adjustment groove 37. The adjustment bolt 38 passes through the positioning plate 32 and is threadedly connected to it. The adjustment bolt 38 is rotatably connected to the adjustment plate 39 via a bearing connection. The sidewall of the adjustment plate 39 fits against the sidewall of the adjustment groove 37. In this embodiment, when the end of the adjustment bolt 38 abuts against the positioning plate 32, the adjustment plate 39 extends beyond the adjustment groove 37.

[0049] Reference Figure 1 , Figure 3 and Figure 4 The end face of the adjusting plate 39 away from the mounting block 16 is inclined, and the inclination direction of the adjusting plate 39 is parallel to the inclination direction of the end face of the positioning plate 32 away from the mounting block 16.

[0050] The operator can press the abutment plate 22 to squeeze the positioning plate 32 and drive the positioning plate 32 to rotate, thereby limiting the abutment plate 22. When it is necessary to adjust the limiting effect, simply rotate the adjusting bolt 38 to adjust the position of the adjusting plate 39 so that both the positioning plate 32 and the adjusting plate 39 can limit the abutment plate 22.

[0051] The operating principle of a coaxial tube bending angle positioning device is as follows: the operator first fixes the mounting base 11 in the corresponding position, and then presses the abutment plate 22 to make the mounting rod 21 slide along the mounting block 16 until the mounting rod 21 abuts against the corresponding position of the workpiece, thus completing the positioning of the workpiece.

[0052] The spring can prevent excessive contact between the mounting rod 21 and the workpiece, thus avoiding damage to the workpiece.

[0053] During the process of limiting the abutment plate 22, the operator presses the abutment plate 22 to squeeze the positioning plate 32, causing the positioning plate 32 to rotate along the fixing rod 31. When it is necessary to adjust the positioning effect, simply rotate the adjusting bolt 38 to make the adjusting plate 39 slide out of the adjusting groove 37, thereby completing the limiting of the abutment ring by the adjusting plate 39, avoiding manual limiting by the operator.

[0054] When it is necessary to release the limit, simply rotate the fixing rod 31. At this time, the adjusting plate 39 and the positioning plate 32 will no longer be released from the abutment plate 22, thereby releasing the limit.
