[0031] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0032] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0033] See also Figure 1 Some embodiments of the present application provide an end face flattening machine 100 for milling the end face of a graphite electrode blank 200 and detecting whether the end face of the graphite electrode blank 200 is flat.

[0034] Specifically, the end face flattening machine 100 includes: a milling mechanism 10 and a flatness detection mechanism 20, the milling mechanism 10 is used to mill the end face of the graphite electrode blank 200, and the flatness detection mechanism 20 is used to detect the flatness of the end face of the graphite electrode blank 200 after milling.

[0035] Specifically, the flatness detection mechanism 20 includes: a first driving member 21 and a flatness detection unit 23 , the first driving member 21 is used to drive the flatness detection unit 23 to move, and the flatness detection unit 23 is used to detect the flatness of the end surface of the graphite electrode blank 200 .

[0036] The end face flattening machine 100 of the present application detects the cutting amount of the end face of the graphite electrode blank 200 before milling by setting the flatness detection mechanism 20, thereby controlling the milling mechanism 10 to move to a suitable position to complete the milling of the end face of the graphite electrode blank 200. In this way, the end face flattening machine 100 accurately grasps the cutting amount of the graphite electrode blank 200, and the yield of the graphite product is high.

[0037] Furthermore, since the cutting amount of the end face of the graphite electrode blank 200 is obtained in advance by the flatness detection mechanism 20, the milling mechanism 10 can be moved to a suitable position in advance according to the cutting amount, and the milling of the end face of the graphite electrode blank 200 can be completed at one time. The milling mechanism does not need to perform multiple feeds and retracts, which has high work efficiency and saves time.

[0038] It should be noted that the first driving member 21 can be a driving motor, which drives the flatness detection unit 23 to move directly or indirectly. For example, the driving motor moves directly with the flatness detection unit 23; or, the driving motor drives the flatness detection unit 23 to move through a transmission structure.

[0039] In a specific embodiment, the flatness detection mechanism 20 further includes a stage, and the flatness detection unit 23 is disposed on the stage; the driving member is used to drive the stage to move, and the movement of the stage drives the flatness detection unit 23 to move.

[0040] The stage provides an installation position for the flatness detection unit 23 , so that the installation of the flatness detection unit 23 is stable and reliable.

[0041] Furthermore, the stage is a turntable 22, and the flatness detection unit 23 is arranged at a non-center position on the side of the turntable 22 facing the graphite electrode blank 200; the driving member is a first driving motor, and the first driving motor is used to drive the turntable 22 to rotate, so as to drive the flatness detection unit 23 to rotate with the turntable 22.

[0042] It should be noted that the non-center position of the turntable 22 refers to a non-circular center position. When the flatness detection unit 23 is in a non-circular position, the detection range will change during the rotation of the turntable 22 .

[0043] When the graphite electrode blank 200 is cylindrical, that is, the cross-sections of both ends of the graphite electrode blank 200 are circular, during the rotation of the turntable 22, the flatness detection unit 23 obtains the difference information between the highest point and the lowest point of the end surface, and transmits the information to the computer for data analysis to obtain the conclusion of flatness.

[0044] In other embodiments, when the graphite electrode blank 200 is a quadrangular prism, that is, the end face of the quadrangular prism is a rectangle, the driving member can also drive the stage to move up and down, left and right, for example, in an S-shaped path under a preset plane, so as to drive the flatness detection unit 23 to detect the flatness of the entire end face.

[0045] In a specific embodiment, the flatness detection unit 23 is an infrared measuring device.

[0046] The infrared measuring device has the advantages of no direct contact with the workpiece, short response time, high measurement accuracy, strong adaptability, etc., and is very suitable for the scene of end face detection of the graphite electrode blank 200. The flatness detection unit can also be a laser sensor. Of course, the flatness detection unit 23 can also adopt a contact displacement sensor.

[0047] The end flattening machine 100 further includes a transmission mechanism 30, which is used to drive the graphite electrode blank 200 placed thereon to move along a first direction. The milling mechanism 10 and the flatness detection unit 23 are arranged along the first direction. Figure 1 The direction of the arrow.

[0048] Specifically, the end face flattening machine 100 includes two sets of flatness detection mechanisms 20 , and the two sets of flatness detection mechanisms 20 are respectively arranged on both sides of the milling mechanism 10 .

[0049] Correspondingly, the transmission mechanism 30 is provided with a first detection station 31 and a second detection station 33 corresponding to the two flatness detection units 23 respectively, and a processing station 32 corresponding to the milling mechanism 10 .

[0050] Exemplarily, when the graphite electrode blank 200 moves to the first inspection station 31, the flatness inspection mechanism 20 inspects the flatness of the end surface of the graphite electrode blank 200. When the graphite electrode blank 200 moves to the milling station, the milling mechanism 10 mills the end surface of the graphite electrode blank 200.

[0051] The transmission mechanism 30 can save manpower and improve detection efficiency. In addition, the transmission mechanism 30 is provided with multiple workstations at the same time, and the multiple workstations can work at the same time, further improving the detection efficiency of the end flattening machine 100.

[0052] Furthermore, the milling process of the graphite electrode blank 200 can be divided into three steps: a cutting amount detection step, a milling step, and a material unloading step. The graphite electrode blank 200 sequentially undergoes the cutting amount detection step, the milling step, and the material unloading step.

[0053] When only one graphite electrode blank 200 is subjected to the milling process, the workflow is as follows:

[0054] The graphite electrode blank 200 is tested for cutting amount at the first testing station 31 to determine the cutting amount. Afterwards, driven by the transmission mechanism 30, the graphite electrode blank 200 enters the processing station 32 for end face milling. After milling, the graphite electrode blank 200 enters the second testing station 33 driven by the transmission mechanism 30 and is unloaded at the second testing station 33. That is, the cutting amount detection process is performed at the first testing station 31, the milling process is performed at the processing station 32, and the unloading process is performed at the second testing station 33.

[0055] In another embodiment, the cutting amount detection process may be performed at the second detection station 33 , the milling process may be performed at the processing station 32 , and the unloading process may be performed at the first detection station 31 .

[0056] When there are multiple graphite electrode blanks 200 undergoing the milling process, the workflow is as follows: In one embodiment, one of the graphite electrode blanks 200 moves from the first inspection station 31 to the processing station 31, and completes milling at the processing station 32. At this time, the first inspection station 31 is left idle, and another graphite electrode blank 200 is placed at the second inspection station 33. Afterwards, one of the graphite electrode blanks 200 is transported to the first inspection station 31 by the transmission mechanism 30, and unloading is completed at the first inspection station 31. Another graphite electrode blank 200 enters the processing station 32.

[0057] In another embodiment, when one graphite electrode blank 200 arrives at the processing station 32, another graphite electrode blank 200 can be placed in the first inspection station 31; when the graphite electrode blank 200 arrives at the second inspection station 33 and another graphite electrode blank 200 arrives at the processing station 32, another graphite electrode blank 200 can be placed in the first inspection station 31.

[0058] In this way, the end face flattening machine can run three graphite electrode blanks 200 at the same time, which greatly improves the production efficiency of the end face flattening machine.

[0059] Of course, it is conceivable that the end face flattening machine can also be configured to have only the milling mechanism 10 and the flatness detection mechanism 20 corresponding to the first detection station 31, or the end face flattening machine can also be configured to have only the milling mechanism 10 and the flatness detection mechanism 20 corresponding to the second detection station 33. The transmission mechanism 30 can be a combination of a drive motor and a conveyor belt, or other mechanisms capable of driving the graphite electrode blank 200 to perform linear motion in the first direction, and this structure is a prior art and will not be described in detail.

[0060] Specifically, a set of flatness detection mechanisms 20 includes two flatness detection mechanisms arranged along the second direction. The second direction is perpendicular to the first direction. Figure 1 In the direction of the arrow.

[0061] See also Figure 1 to Figure 3 In some embodiments of the present application, a milling mechanism 10 is provided for milling the end surface of a graphite electrode blank 200 .

[0062] The milling mechanism 10 includes: a base 11, a second driving member 12, a movable seat 13 and a milling assembly 14. The second driving member 12 is arranged on the base 11, and is used to drive the movable seat 13 to move back and forth in a straight line along the second direction; the milling assembly 14 is arranged on the movable seat 13, and can contact the end surface of the graphite electrode blank 200 under the drive of the movable seat 13.

[0063] Specifically, the milling mechanism 10 includes: two movable seats 13 arranged along the second direction, and the two movable seats 13 are configured to move toward or relative to each other along the second direction; wherein the first direction and the second direction are arranged perpendicular to each other.

[0064] In the non-working state, the spacing between the two moving seats 13 is configured to allow the graphite electrode blank 200 to extend therein. When the graphite electrode blank moves to the processing station, the second driving member 12 drives the two milling mechanisms 10 to move toward each other, thereby milling the graphite electrode blank entering the processing station. After the milling is completed, the second driving member 12 drives the two milling mechanisms 10 to move back and forth, so that the transmission mechanism drives the graphite electrode blank 200 to leave the processing station, and the graphite electrode blank to be milled can enter the processing station.

[0065] Furthermore, the milling assembly 14 includes: a third driving member 141 , a first milling disc 142 , a second milling disc 143 and a fourth driving member 144 .

[0066] The output shaft of the third driving member 141 is connected to the first milling disk 142 , so that the third driving member 141 drives the first milling disk 142 to pivot.

[0067] The fourth driving member 144 is disposed on the first milling disk 142. The second milling disk 143 is connected to the output shaft of the fourth driving member 144, so that the fourth driving member 144 drives the second milling disk 143 to pivot.

[0068] In some embodiments, the fourth driving member 144 is disposed at a non-central position of the first milling disk 142. Driven by the third driving member 141, the fourth driving member 144 pivots around the central axis of the first milling disk 142. The second milling disk 143 is connected to the output shaft of the fourth driving member 144, so that the fourth driving member 144 drives the second milling disk 143 to pivot.

[0069] Since the fourth driving member 144 is arranged at a non-central position of the first milling disc 142, the second milling disc 143 revolves around the central axis of the first milling disc 142 and rotates under the drive of the fourth driving member 144. The self-rotation and revolution of the first milling disc 142 can increase the working range of the milling assembly 14 to meet the needs of large-section graphite electrode blanks 200. In addition, when cutting the graphite electrode blank 200, the milling mechanism 10 does not need to feed from the side for processing, so dust is small and energy is saved.

[0070] When the graphite electrode blank 200 enters the processing station, the third driving member 141 drives the first milling disc 142 to rotate, thereby driving the second milling disc 143 to revolve around the center point of the first milling disc 142, thereby performing preliminary milling on the cross section of the graphite electrode blank. The fourth driving member 144 drives the second milling disc 143 to rotate, so as to further mill the cross section of the graphite electrode blank.

[0071] In some embodiments, the first milling disc 142 is provided with a mounting groove, a positioning clamping plate 145 is provided in the mounting groove, and the second milling pin disc 143 and the fourth driving member 144 are respectively provided on both sides of the positioning clamping plate 145 .

[0072] The positioning card plate 145 is used to install the fourth driving member 144, and the installation is stable and reliable. In addition, the fourth driving member 144 and the second milling disk 143 are distributed on both sides of the positioning card plate 145, and the configuration is reasonable, and the operation of the milling assembly 14 is stable and reliable.

[0073] The milling assembly 14 further includes a dust cover 15 , and the dust cover 15 is disposed on the milling assembly 14 .

[0074] By providing a dust cover 15 and making the dust cover 15 cover the milling assembly 14, the dust generated during the milling process is all in the dust cover 15. The operator only needs to clean the dust regularly, and there is no need to use wind blowing dust removal or spraying dust removal to add an extra fan or spraying system, which has a simple structure and saves energy and reduces consumption.

[0075] Furthermore, the dust cover 15 has an opening toward the graphite electrode blank 200 , and the opening enables the graphite electrode blank 200 to be inserted and extended.

[0076] Both ends of the graphite electrode blank 200 extend into the dust cover 15 , and the milling assembly 14 performs end milling of the graphite electrode blank 200 , and the milling is stable and reliable under the interference of the outside world.

[0077] In some specific embodiments, the milling mechanism 10 further includes: a base 11 and a second driving member 12 , and a moving seat 13 is movably disposed on the base 11 ; the second driving member 11 is used to drive the moving seat 12 to move.

[0078] The second driving member 12 drives the moving seat 13 to move, and causes the milling assembly 14 disposed on the moving seat 13 to contact or separate from the end surface of the graphite electrode blank 200 .

[0079] In some specific implementations, the cross-sectional area of ​​the first milling pin disk 142 is s1, the cross-sectional area of ​​the second milling pin disk 143 is s2, and s2:s1≤1:2.

[0080] By reasonably configuring the cross-sectional sizes of the first milling disk 142 and the second milling disk 143, when the first milling disk 142 pivots, the movement path of the second milling disk 143 can cover the end faces of graphite electrode blanks 200 of different sizes, so as to adapt to the production and processing of conductive and 200 of different sizes, and has a wide range of application scenarios.

[0081] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom still fall within the scope of protection created by this application.
