[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] Reference Figs. 1-2 A diameter measuring mechanism for copper rod drawing, comprising: a fixed part 1, which is annular structure; a rotating part 2, which is also annular structure, and is sleeved on one end of the fixed part 1; at least two displacement sensors 3, which are arranged on the end of the rotating part 2 away from the fixed part 1, and are oppositely arranged for measuring the diameter of the copper rod 5; and a locking part 4, which is arranged on the rotating part 2 for locking the rotating angle of the rotating part 2.

[0026] It can be understood that the rotating part 2 is sleeved, which can be directly sleeved or sleeved with bearings and the like. The displacement sensor 3 can be a non-contact laser displacement sensor 3, or can be realized by combining a contact elastic pressure roller with a linear variable differential transformer, but is not limited thereto. The locking part 4 can be a screw or a connecting structure such as a screw, which connects and locks the rotating part 2 and the fixed part 1, or can adopt a clamping ring structure, which clamps and fixes the end of the fixed part 1 and the rotating part 2, but is not limited thereto. The two oppositely arranged displacement sensors 3 are a group, and multiple groups can be arranged to simultaneously detect the diameter of the position of the copper rod 5.

[0027] In this way, the copper rod 5 is sleeved on the fixed part 1 and the rotating part 2, and the diameter of the copper rod 5 is detected by the displacement sensor 3. Furthermore, the rotating part 2 can rotate on the fixed part 1, thereby rotating the displacement sensor 3 on the rotating part 2, so that the diameter of any position on the copper rod 5 can be detected, that is, multi-point diameter measurement, thereby comprehensively improving the diameter measurement accuracy.

[0028] In some embodiments, the fixed part 1 comprises a base ring 11 and an embedded ring 12 arranged at one end of the base ring 11 and having an outer diameter smaller than that of the base ring 11; and the rotating part 2 is sleeved on the embedded ring 12. Further, the rotating part 2 comprises a rotating ring 21 and a positioning ring 22 arranged at one end of the rotating ring 21 and having an outer diameter larger than that of the rotating ring 21; the positioning ring 22 is sleeved on the base ring 11, the rotating ring 21 is sleeved on the embedded ring 12; and the locking part 4 is arranged on the positioning ring 22. Here, the base ring 11 and the embedded ring 12, and the rotating ring 21 and the positioning ring 22 can be integrally formed or welded, etc. In this way, the positioning ring 22 is sleeved on the base ring 11, and the rotating ring 21 is sleeved on the embedded ring 12, and the sleeving of the two can enhance the stability of the rotating sleeve between the fixed part 1 and the rotating part 2. The locking part 4 is arranged on the positioning ring 22, and the locking part 4 can act on the base ring 11 without damaging the embedded ring 12, thereby ensuring the smooth rotation between the rotating ring 21 and the embedded ring 12.

Here, when the positioning ring 22 is thin, the threaded seat 41 can enhance the stability of the positioning of the bolt 42. Of course, when the positioning ring 22 is thick, the threaded seat 41 can be omitted and a threaded hole can be directly formed on the positioning ring 22. In this way, the bolt 42 is tightened to lock the position of the rotating member 2. Further, the outer wall of the base ring 11 is provided with a ring groove 111 corresponding to the bolt 42, and the bolt 42 is threaded into the ring groove 111. In this way, the bottom of the bolt 42 is embedded in the ring groove 111 to lock the axial direction of the rotating member 2. Further, the locking member 4 is arranged at intervals along the outer ring of the positioning ring 22. In this way, multi-point positioning is achieved to improve the stability of the position of the rotating member 2.

[0030] In some embodiments, the rotating ring 21 is provided with an outwardly extending connecting piece 7 at the end away from the positioning ring 22, and the displacement sensor 3 is arranged on the connecting piece 7. Here, the connecting piece 7 can be integrally arranged on the rotating member 2, or can be connected and fixed by using a clamping piece structure or a screw, etc. In this way, the displacement sensor 3 is located on the outer side of the rotating member 2, which facilitates the installation and observation of the displacement sensor 3.

[0031] In some embodiments, the base ring 11 is provided with a base 6 at the bottom, and the base 6 is used to fix the diameter measuring mechanism for the copper rod drawing. Here, the base 6 can be a reverse T-shaped structure, or a rod body structure, etc. The base 6 is fixed on the body of the drawing machine by a connecting member such as a bolt 42 to measure the diameter of the copper rod 5 on the drawing machine.
