Description

Technical Field

[0001] This utility model relates to the field of cathode carbon block processing technology, and in particular to a cutter disc for processing scratches on cathode carbon blocks. Background Technology

[0002] Graphitized cathode carbon blocks are widely used in modern high-current aluminum electrolytic cells. Scratches are applied to the sides and ends of the carbon blocks to increase the contact area between the carbon blocks and the carbon paste, improving their bonding performance and strength. This reduces the likelihood of cracking during the start-up of the electrolytic cell and extends its service life. Because the end and side properties of the cathode carbon blocks differ, scratches at different intervals are required on both sides. Current technology involves machining the scratches on a machine tool using a cutter head. The cutter head is an integral structure with a non-adjustable cutter head position. This means that at least two cutter heads are needed to process one cathode carbon block. After machining one side, the finished cutter head is removed and replaced with a new one. After machining one end face, not only does the position of the cathode carbon block need to be adjusted, but the cutter head also needs to be disassembled and replaced. When machining other sides, the cutter head needs to be re-aligned. The entire process is complex and inefficient. Utility Model Content

[0003] In view of the technical problems existing in the background art, the purpose of this utility model is to provide a cutter head for processing scratches on cathode carbon blocks, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: A cutter disc for machining scratches on cathode carbon blocks includes a pad, a clamping plate, an adjusting plate, and several cutters. One end of the pad is provided with a groove, and the cutters are slidably connected in the groove, with one end of each cutter extending out of the groove. The adjusting plate is disposed between adjacent cutters, and when adjacent cutters abut against both sides of the adjusting plate, the distance between adjacent cutters is the same as the spacing of the scratches. The clamping plate is connected above the groove and is detachably connected to one end of the pad, capable of clamping the cutters in the groove.

[0005] Preferably, the adjustment plates are provided in several groups, and the width of each group of adjustment plates is different.

[0006] Preferably, the cutting tool includes a tool holder and a cutting head, the cutting head being disposed at one end of the tool holder, the tool holder being disposed within a groove, and the cutting head extending out from the groove.

[0007] Preferably, the tool also includes a support member, and a support hole is provided in the middle of the tool holder. The support member is connected in the support hole, and one end of the support member protrudes above the tool holder.

[0008] Preferably, the support component is an internal hex bolt.

[0009] Preferably, the clamping plate is provided with a connecting hole I, and the pad is provided with a connecting hole II, with the connecting hole I and the connecting hole II aligned.

[0010] Preferably, the clamping plate and the support member abut against each other.

[0011] Preferably, a stop block is provided inside the pad, and the stop block is located at one end of the channel.

[0012] This utility model has the following advantages and beneficial effects: In this utility model: 1. Several cutting tools are slidably connected between the pad and the clamping plate. Several sets of adjustment plates are provided, and the width of each set of adjustment plates is different. The width of the adjustment plates is designed according to the spacing of the scratches. The adjustment plates of different widths are inserted between adjacent cutting tools so that the spacing between the cutting tools is the same as the required scratch spacing. This method does not require multiple cutting heads, nor does it require replacing the entire cutting head after machining one end face, which greatly increases the machining efficiency.

[0013] Second, the stop is set at one end of the channel to restrict the sliding of the tool. Using this method for positioning, after machining one end face, you only need to make the first tool close to the stop and readjust the spacing of the remaining tools. There is no need to re-set the tool. This not only ensures normal machining accuracy, but also reduces the time and difficulty required for overall machining. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] Example like Figures 1-5 As shown, a cutter head for machining scratches on cathode carbon blocks includes a pad plate 3, a clamping plate 2, an adjusting plate 5, and several cutters 4. The cutters 4 are slidably connected between the pad plate 3 and the clamping plate 2. The clamping plate 2 is connected above the pad plate 3 and is detachably connected to one end of the pad plate 3, which can clamp the cutters 4 between the pad plate 3 and the clamping plate 2. The pad plate 3 is connected to a machine tool 1. The drive structure of the machine tool 1 is set perpendicular to the ground, that is, the machining direction of the machine tool 1 is perpendicular to the ground direction. The pad plate 3 is fixedly set on the drive structure and is parallel to the ground to prevent the cutter head from tilting. When adjusting the position of the cutters 4, the sliding process of the cutters 4 is stable, reducing the difficulty of adjusting the cutters 4 and greatly increasing the efficiency of the cutter adjustment.

[0019] like Figures 1-5 As shown, the pad 3 has a rectangular structure, and a groove 32 is provided at one end of the pad 3. The groove 32 is located at the upper end of the pad 3. Several cutting tools 4 are slidably connected in the groove 32, with one end of the cutting tool 4 extending out of the groove 32. The groove 32 is a groove structure parallel to the pad 3. The cutting tool 4 includes a tool holder 41, a support member 43, and a cutting head 42. The cutting head 42 is located at one end of the tool holder 41, which is located in the groove 32. The cutting head 42 extends out of the groove 32, and the end of the tool holder 41 is in contact with the inner wall of the groove 32. When the cutting tool 4 slides, the groove 32 acts as a limiter. When the cutting tool 4 slides, the end of the cutting tool 4 is in contact with the groove 32 throughout the entire process, so that each cutting tool 4 can slide in the same straight line direction, making the sliding process of the cutting tool 4 more stable and accurate.

[0020] like Figures 1-5As shown, a support hole 44 is provided in the middle of the tool holder 41. A support member 43 is connected in the support hole 44. The support member 43 is an internal hex bolt. The support member 43 and the support hole 44 are connected by threads. One end of the support member 43 protrudes above the tool holder 41. When the clamping plate 2 and the pad 3 are connected, the lower end of the clamping plate 2 abuts against the upper end of the support member 43. Considering that the tool 4 is installed and fixed by clamping, the clamping position of the tool 4 is prone to damage after long-term use. Therefore, a detachable support member 43 is designed on the tool holder 41. The support member 43 is used to bear the pressure of the clamping plate 2. The clamping plate 2 directly abuts against the support member 43. This not only ensures the clamping strength of the tool 4, but also allows the damaged support member 43 to be removed and a new support member 43 to be connected in the support hole 44 when the support member 43 is damaged. This not only protects the structure of the tool holder 41 and the tool head 42 to the greatest extent, but also further extends the overall service life of the tool disc. The clamp 2 is connected above the channel 32 without completely blocking the channel 32, which makes it easy for workers to observe the position of the tool 4 in a timely manner, and also makes it easy to observe the wear of the support 43.

[0021] The clamping plate 2 is provided with several connecting holes I21, which penetrate through the clamping plate 2. The pad 3 is provided with several connecting holes II31, which are aligned. The connecting holes I21 and II31 are threaded holes with internal thread sections. When the clamping plate 2 and the pad 3 are connected, the connecting holes I21 and II31 are aligned. The bolts are screwed into the connecting holes I21 and II31, thus connecting the clamping plate 2 and the pad 3. The clamping plate 2 and the pad 3 are connected in a detachable manner, which not only has high connection strength but also a simple connection method and an efficient connection process.

[0022] A stop 33 is provided inside the pad 3. The stop 33 is located at one end of the channel 32 to restrict the sliding of the tool 4 and to position the tool 4. Several tools 4 are slidably connected in the channel 32. When the tool 4 close to the stop 33 is in contact with the stop 33, the position of the tool 4 is the position of the first scratch. Using this method for positioning, after machining one end face, it is only necessary to make the first tool 4 close to the stop 33 and readjust the spacing of the remaining tools 4. There is no need to re-set the tool. This not only ensures normal machining accuracy but also reduces the time and difficulty required for overall machining.

[0023] Adjusting plates 5 are positioned between adjacent cutting tools 4 and are inserted into each other. When adjacent cutting tools 4 abut against both sides of the adjusting plate 5, the distance between adjacent cutting tools 4 is the same as the spacing of the scratches. Several sets of adjusting plates 5 are provided, and each set of adjusting plates 5 has a different width. When the spacing of the scratches to be processed is large, a wider adjusting plate 5 is selected and inserted between adjacent cutting tools 4. At this time, the distance between adjacent cutting tool heads 42 is the spacing required for the scratches during processing (large-spacing scratches). When the spacing of the scratches to be processed is small, a narrower adjusting plate 5 is selected. Adjust the adjusting plate 5 so that it is inserted between adjacent cutting tools 4. At this time, the distance between adjacent cutting tool heads 42 is the distance required for the scratch during processing (small-pitch scratch). After adjustment, pull out the adjusting plate 5. After processing one end face, select the adjusting plate 5 of different widths according to the required scratch spacing. After removing the clamping plate 2, insert the corresponding adjusting plate 5 between adjacent cutting tools 4 and adjust the position of the cutting tools 4 so that the distance between the cutting tools 4 is the same as the scratch spacing. Then connect the clamping plate 2 and the pad 3 so that the cutting tool 4 is fixed between the clamping plate 2 and the pad 3.

[0024] This is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
