[0001] The utility model belongs to the technical field of graphite electrode detection, and in particular relates to a graphite electrode diameter measuring device. Background Art

[0002] In order to solve the problem that the manual measurement of graphite electrodes using calipers or π rulers is limited by the operator's level, the measurement results have large errors and low precision, and the measurement difficulty increases with the increase of the diameter of the graphite electrode, the utility model patent with authorization announcement number CN218884924U discloses a graphite electrode diameter measuring device, which includes a bottom plate, a sliding column, a top plate, a first distance measuring instrument, a second distance measuring instrument and a support tube. The number of the support tubes is two and they are arranged at the same height on the bottom plate. The first distance measuring instrument is arranged on the bottom plate, and the first distance measuring instrument is directly opposite to the symmetry line of the two support tubes. The working end of the first distance measuring instrument is flush with the top surface of the bottom plate. The number of the sliding columns is two and they are vertically arranged on the bottom plate. The two ends of the top plate are longitudinally slidably connected to the sliding columns. The second distance measuring instrument is arranged on the top plate, and the working end of the second distance measuring instrument is flush with the bottom surface of the top plate. The first distance measuring instrument is parallel to the second distance measuring instrument.

[0003] However, the above mechanism has the following problems: the length specifications of graphite electrodes are different and are generally long. The first distance measuring instrument and the second distance measuring instrument can only measure the diameter of the graphite electrode at the measuring point, and cannot measure the diameter at any position on the entire graphite electrode. Therefore, the measurement accuracy is low, and the measurement result is prone to a large deviation from the actual diameter range of the graphite electrode. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a graphite electrode diameter measuring device to solve the problem that the existing graphite electrode diameter measuring device cannot quickly and conveniently measure the diameter of any position on the entire graphite electrode, so the measurement accuracy is low and the measurement result is easy to deviate greatly from the actual diameter range of the graphite electrode.

[0005] To achieve the above purpose, the utility model adopts the following technical solution: a graphite electrode diameter measuring device, comprising a connecting frame, a main machine and a support frame are respectively installed at both ends of the connecting frame, a driving roller, a supporting roller and a lead screw are rotatably installed on the main machine and the support frame, and the main machine and the support frame connect the two ends of a lower polished rod and an upper polished rod, the driving roller and the lead screw are respectively connected to the output shafts of a driving motor and a lead screw motor, the driving motor and the lead screw motor are installed on the support frame, a measuring piece is transmission-connected to the lead screw, the measuring piece is slidably mounted on the outer side of the lower polished rod, and a positioning piece one and a positioning piece two are slidably mounted on the outer sides of the lower polished rod and the upper polished rod, the measuring piece comprises a sliding block, a lead screw nut threadedly connected to the lead screw is installed on the sliding block, and a displacement sensor is installed on the top of the sliding block.

[0006] The beneficial effects of the present utility model are as follows: when the graphite electrode rotates slowly driven by the driving roller, the measuring member moves along the axis of the graphite electrode driven by the lead screw, so as to comprehensively and accurately detect the diameter range of the whole graphite electrode.

[0007] In order to accurately detect the diameter of the graphite electrode during the movement of the measuring member;

[0008] As a further improvement of the above technical solution: the axes of the lead screw and the lower optical rod are parallel to the axes of the driving roller and the supporting roller.

[0009] The beneficial effect of this improvement is that after the graphite electrode is supported by the rolling of the driving roller and the supporting roller, the measuring member can move along the axial direction of the graphite electrode driven by the lead screw motor, so as to accurately detect the diameters of different parts in the axial direction of the graphite electrode.

[0010] In order to enable the displacement sensor to accurately detect the diameter of the graphite electrode;

[0011] As a further improvement of the above technical solution: the axis of the displacement sensor is perpendicular to the plane where the axes of the driving roller and the supporting roller are located, and the driving roller and the supporting roller are symmetrically arranged with the axis of the displacement sensor as the symmetry axis.

[0012] The beneficial effect of this improvement is that after the graphite electrode is supported by the rolling of the driving roller and the supporting roller, the displacement sensor can accurately measure the diameter change of the graphite electrode.

[0013] In order to ensure the stability of the connection between the main machine and the support frame;

[0014] As a further improvement of the above technical solution: the number of the connecting frames is multiple, and the connecting frames are of channel steel structure.

[0015] The beneficial effect of this improvement is that multiple connecting frames can stably connect the main machine and the support frame.

[0016] In order to improve the detection speed of the device for the graphite electrode;

[0017] As a further improvement of the above technical solution: the first positioning member and the second positioning member have the same structure and size and are oppositely arranged. The first positioning member includes a moving block, an installation plate is arranged on the moving block, a travel switch is installed on the installation plate, the travel switch is electrically connected to the main machine, and the moving block is slidably sleeved outside the lower optical rod and the upper optical rod.

[0018] The beneficial effect of this improvement is that the operator can adjust the positions of the first positioning member and the second positioning member according to the length of the graphite electrode, so that the lead screw motor reverses or stops rotating after the measuring member touches the travel switch, avoiding the ineffective movement of the measuring member after the measurement is completed and affecting the measurement time.

[0019] In order to quickly locate the position of the first positioning member;

[0020] As a further improvement of the above technical solution: a positioning plate is provided on the end face of one end of the moving block facing the supporting roller.

[0021] The beneficial effect of this improvement is that the operator can slide the moving block to make the positioning plate press against the end face of the graphite electrode.

Detailed Implementation Modes

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0029] Embodiment 1:

[0030] As Figure 1As shown in Fig. 4, a graphite electrode diameter measuring device includes a connecting frame 1. At both ends of the connecting frame 1, a main machine 2 and a support frame 3 are respectively installed. A driving roller 10, a support roller 11 and a lead screw 4 are rotatably installed on the main machine 2 and the support frame 3. And the two ends of a lower optical rod 6 and an upper optical rod 7 are connected to the main machine 2 and the support frame 3. The driving roller 10 and the lead screw 4 are respectively connected to the output shafts of a driving motor 12 and a lead screw motor 5. The driving motor 12 and the lead screw motor 5 are installed on the support frame 3. A measuring member 8 is drivingly connected to the lead screw 4. The measuring member 8 is slidably sleeved outside the lower optical rod 6. A first positioning member 9 and a second positioning member 13 are slidably sleeved outside the lower optical rod 6 and the upper optical rod 7. The measuring member 8 includes a sliding block 81. A lead screw nut 82 threadedly connected to the lead screw 4 is installed on the sliding block 81. A displacement sensor 83 is installed at the top of the sliding block 81. When the graphite electrode rotates slowly under the drive of the driving roller 10, the measuring member 8 moves along the axis of the graphite electrode under the drive of the lead screw 4, so as to comprehensively and accurately detect the diameter range of the whole graphite electrode. The axes of the lead screw 4 and the lower optical rod 6 are parallel to the axes of the driving roller 10 and the support roller 11. After the graphite electrode is rollingly supported by the driving roller 10 and the support roller 11, the measuring member 8 can move along the axial direction of the graphite electrode under the drive of the lead screw motor 5, so as to accurately detect the diameters of different parts in the axial direction of the graphite electrode. The axis of the displacement sensor 83 is perpendicular to the plane where the axes of the driving roller 10 and the support roller 11 are located. The driving roller 10 and the support roller 11 are symmetrically arranged with the axis of the displacement sensor 83 as the symmetry axis. After the graphite electrode is rollingly supported by the driving roller 10 and the support roller 11, the displacement sensor 83 can accurately measure the diameter change of the graphite electrode. The number of the connecting frames 1 is multiple. The connecting frame 1 is made of channel steel. The multiple connecting frames 1 can stably connect the main machine 2 and the support frame 3. The first positioning member 9 and the second positioning member 13 have the same structure and size and are oppositely arranged. The first positioning member 9 includes a moving block 91. An installation plate 93 is arranged on the moving block 91. A travel switch 94 is installed on the installation plate 93. The travel switch 94 is electrically connected to the main machine 2. The moving block 91 is slidably sleeved outside the lower optical rod 6 and the upper optical rod 7. The operator can adjust the positions of the first positioning member 9 and the second positioning member 13 according to the length of the graphite electrode, so that the lead screw motor 5 reverses or stops rotating after the measuring member 8 touches the travel switch 94, avoiding the ineffective movement of the measuring member 8 after the measurement is completed and affecting the measurement time. A positioning plate 92 is arranged on the end face of the moving block 91 facing the support roller 11. The operator can slide the moving block 91 to make the positioning plate 92 press against the end face of the graphite electrode.

[0031] The working principle of this technical solution is as follows: Place the graphite electrode on the driving roller 10 and the supporting roller 11, slide the positioning member one 9 and the positioning member two 13, so that the positioning plates 92 on the positioning member one 9 and the positioning member two 13 are abutted against the two end faces of the graphite electrode. Subsequently, start the lead screw motor 5 and the driving motor 12 through the main machine 2; when the driving motor 12 operates, it drives the driving roller 10 to rotate, thereby making the graphite electrode rotate at a low speed; when the lead screw motor 5 operates, it drives the lead screw 4 to rotate, thereby making the measuring member 8 move parallel to the axis of the graphite electrode under the support and guidance of the lower optical rod 6, and measure whether the diameter of the entire graphite electrode is within the qualified range through the displacement sensor 83 located directly below the graphite electrode; when the slider 81 touches the travel switch 94 installed on the positioning member one 9 or the positioning member two 13, the lead screw motor 5 reverses under the control of the main machine 2, making the measuring member 8 move in the reverse direction, so that the measuring member 8 can measure the diameter of the entire graphite electrode.
