Description

Technical Field

[0001] The present application relates to the field of machine or equipment cleaning, and in particular, to a tool kit. Background Art

[0002] Carbon electrodes are widely used in metallurgy, chemical industry, electrochemistry and other fields, and are a commonly used industrial electrode. However, carbon electrodes need to be baked during the processing. After baking, a large amount of residue is attached to the surface of the carbon electrode. These residues need to be removed before the carbon electrode is finally put into use. The traditional removal process is done manually, which is inefficient and costly. In addition, since some carbon electrodes have complex surface profiles, general grinding tools are less effective in removing residues attached to the surface of carbon electrodes. Therefore, there is a need in the market for a tool kit that can clean more complex carbon electrode surfaces or the outer surfaces of other devices, machines or equipment with more complex surface profiles.

[0033] Figure 1 is a schematic diagram of a tool kit 1000 according to an embodiment of the present application. Figure 1 The tool kit 1000 includes a concave tool 1100, a convex tool 1200 and a flat tool 1300 arranged along the direction of the X-axis.

[0034] Figure 2 is an enlarged schematic diagram of a tool kit 1000 according to an embodiment of the present application. Figure 2, the concave tool 1100 includes multiple groups of concave tool heads 1110, and each group of tool heads in the multiple groups of concave tool heads 1110 has a concave arc blade along the direction of the X-axis. The convex tool 1200 includes multiple groups of convex tool heads 1210, and each group of tool heads in the multiple groups of convex tool heads 1210 has a convex arc blade along the direction of the X-axis. The planar tool 1300 includes multiple groups of planar tool heads 1310, and the multiple groups of planar tool heads 1310 extend toward the X-axis direction, and the cutting edges of the multiple groups of planar tool heads are located in the YZ plane formed by the Y axis and the Z axis perpendicular to the X axis. In the present application, the Y axis and the Z axis may be perpendicular to each other. According to an embodiment of the present application, the multiple groups of concave tool heads 1110 and the multiple groups of convex tool heads 1210 may be arranged in a spiral around the X axis.

[0035] Figure 3 3000 is a schematic diagram of the outline of the carbon electrode. Generally speaking, the carbon electrode has an irregular shape. For example, Figure 3 The carbon electrode 3000 shown includes a convex area 3100 at the edge of the carbon bowl, a concave area 3200 extending from the carbon bowl, and planar areas 3300 and 3400 around the carbon electrode. The tool kit 1000 according to the embodiment of the present application can effectively grind the various surfaces of the carbon electrode 3000 and efficiently remove the residues attached to the surface of the carbon electrode 3000. Specifically, the concave tool 1100 of the tool kit 1000 can effectively grind the convex area 3100 of the carbon electrode 3000, the convex tool 1200 of the tool kit 1000 can effectively grind the concave area 3200 of the carbon electrode 3000, and the planar tool 1300 of the tool kit 1000 can effectively grind the planar area 3300 of the carbon electrode 3000. Therefore, the user can effectively grind the various surfaces of the entire carbon electrode 3000 without changing the tool head.

[0036] Figure 4 1 is an enlarged schematic diagram of the concave tool 1100 in the tool kit 1000 according to an embodiment of the present application.

[0037] According to the embodiment of the present application, each group of concave cutter heads in the multiple groups of concave cutter heads 1110 of the concave cutter 1100 includes a first cutter head 1111 and a second cutter head 1112 that are staggered and arranged side by side. The first cutter head 1111 and the second cutter head 1112 in each group of concave cutter heads are tightly fitted together. Along the direction of the X-axis (i.e., the direction of the main tool axis), the cutting edge of the first cutter head 1111 is higher than the cutting edge of the second cutter head 1112 at one end; on the contrary, the cutting edge of the first cutter head 1111 is lower than the cutting edge of the second cutter head 1112 at the other end.

[0038] See also Figure 4, along the direction of the X-axis, the cutting edge of the first cutter head 1111 at the lower end protrudes more outward than the cutting edge of the second cutter head 1112; the cutting edge of the second cutter head 1112 at the upper end protrudes more outward than the cutting edge of the first cutter head 1111. The first cutter head 1111 and the second cutter head 1112 are staggered in the middle area. Therefore, if the working surface of the grinding work of the concave cutter head 1110 is located at the upper end, the second cutter head 1112 contacts the working surface, and if the working surface of the grinding work of the concave cutter head 1110 is located at the lower end, the first cutter head 1111 contacts the working surface.

[0039] In the present application, multiple groups of concave cutter heads 1110 are arranged spirally around the X-axis, and a first cutter head 1111 and a second cutter head 1112 are arranged in an staggered and parallel manner. Therefore, when the concave cutter 1100 rotates to cut (or grind) the working surface, the contact between the concave cutter head 1110 and the carbon electrode 3000 is continuous without any height jump, thereby ensuring smooth grinding and avoiding collision between the cutter head and the working surface due to height jumps during the contact between the cutter head and the working surface, thereby avoiding damage to the cutter head.

[0040] Figure 5 It is an enlarged schematic diagram of the inwardly convex tool 1200 in the tool kit 1000 according to an embodiment of the present application.

[0041] According to the embodiment of the present application, each group of the multiple groups of the inner convex cutter heads 1210 of the inner convex cutter 1200 includes a third cutter head 1211 and a fourth cutter head 1212 that are staggered and arranged side by side. The third cutter head 1211 and the fourth cutter head 1212 in each group of the inner convex cutter heads are tightly fitted together. Along the direction of the X-axis (i.e., the direction of the main tool axis), the cutting edge of the third cutter head 1211 is higher than the cutting edge of the fourth cutter head 1212 at one end; on the contrary, the cutting edge of the third cutter head 1211 is lower than the cutting edge of the fourth cutter head 1212 at the other end.

[0042] See also Figure 5 , along the direction of the X-axis, the cutting edge of the third cutter head 1211 at the upper end protrudes more outward than the cutting edge of the fourth cutter head 1212; the cutting edge of the fourth cutter head 1212 at the lower end protrudes more outward than the cutting edge of the third cutter head 1211. The third cutter head 1211 and the fourth cutter head 1212 are staggered in the middle area. Therefore, if the working surface of the grinding work of the inner convex cutter head 1210 is located at the upper end, the third cutter head 1211 contacts the working surface, and if the working surface of the grinding work of the inner convex cutter head 1210 is located at the lower end, the fourth cutter head 1212 contacts the working surface.

[0043] In the present application, multiple groups of inwardly convex cutter heads 1210 are arranged spirally around the X-axis, and a third cutter head 1211 and a fourth cutter head 1212 are arranged in an staggered and parallel manner. Therefore, when the inwardly convex cutter 1200 rotates to cut (or grind) the working surface, the contact between the inwardly convex cutter head 1210 and the carbon electrode 3000 is continuous, without a height difference jump, thereby ensuring smooth grinding work and avoiding collision between the cutter head and the working surface due to a height difference jump during the contact between the cutter head and the working surface, thereby avoiding damage to the cutter head.

[0044] Figure 6 It is an enlarged schematic diagram of the flat tool 1300 in the tool kit 1000 according to the embodiment of the present application.

[0045] Multiple sets of planar tool holders 1320 are integrally formed on the multiple sets of inner convex tool heads 1210, and the multiple sets of planar tool heads 1310 are respectively fixed on the multiple sets of planar tool holders 1320. The planar tool holders 1320 and the inner convex tool heads 1210 are integrally formed according to the embodiment of the present application, thereby enhancing the structural strength of the tool kit 1000.

[0046] Figure 7 It is an enlarged schematic diagram of the connecting shaft 7000 according to an embodiment of the present application.

[0047] The concave tool 1100 and the convex tool 1200 are fixedly connected by a connecting shaft 7000 extending in the direction of the X-axis. A first screw connection portion 7100 connected to the concave tool 1100 and a second screw connection portion 7200 connected to the convex tool 1200 are respectively arranged on both sides of the connecting shaft 7000. The connecting shaft 7000 has a hollow portion 7300 passing through the direction of the X-axis. The tool kit 1000 has a driving shaft 7400 spline-connected to the hollow portion 7300. The driving shaft 7400 drives the concave tool 1100 and the convex tool 1200 to rotate through the connecting shaft 7000.

[0048] Figure 8 Schematic diagram of a slider 8100 and a fixed frame 8200 according to an embodiment of the present application.

[0049] The tool kit 1000 further includes a slider 8100 fixedly connected to the concave tool 1100 or the convex tool 1200. The slider 8100 is connected to the drive shaft 7400 at its end 8101 to transmit the power to drive the concave tool 1100 and the convex tool 1200 to rotate. In addition, the slider 8100 has a first sliding portion 8110 extending in the direction of the Y axis. The first sliding portion 8100 can be a slide groove, which can be connected to the slide rail.

[0050] The tool kit 1000 also includes a fixed frame 8200 that can move relative to the concave tool 1100 or the convex tool 1200. The fixed frame 8200 can be connected to a robotic arm so as to move according to the movement of the robotic arm. The robotic arm can drive the tool kit 1000 to perform grinding work in the desired working area by moving the fixed frame 8200 to the working area to be ground. The fixed frame 8200 includes a second sliding portion 8210 that is slidably connected to the first sliding portion 8110, and the second sliding portion 8210 can be a slide rail. Since the slider 8100 has the ability to move laterally relative to the fixed frame 8200, when the tool kit 1000 performs grinding work on the surface of the carbon electrode 3000, the tool kit 1000 can be adaptively moved according to the surface contour of the carbon electrode 3000 to avoid excessive grinding of the surface of the carbon electrode 3000.

[0051] A damping resetter (not shown) is provided between the slider 8100 and the fixed frame 8200, and the damping resetter can provide damping or reset force for the movement of the slider 8100 relative to the fixed frame 8200 along the Y-axis. In addition, since the damping resetter can provide damping for such lateral movement, when the tool kit 1000 is grinding on the surface of the carbon electrode 3000, the slider 8100 can apply a force toward the working surface to the tool kit 1000 to help the tool kit 1000 better fit the working surface. The damping resetter can be a spring or a gas pressure damper.

[0052] A limit block 8220 is disposed on one side of the second sliding portion 8210 to prevent the sliding block 8100 from continuing to slide toward a side further away from the fixed frame 8200 .

[0053] Fig. 9 It is a schematic diagram of the connection between the power transmission shaft 8300 and the slider 8100 according to an embodiment of the present application.

[0054] The tool kit 1000 includes a power transmission shaft 8300 connected to the fixed frame 8200 and a three-section coupling 8400 connected to the power transmission shaft 8300 and the slider 8100. The outermost two sections of the three-section coupling 8400 are respectively connected to the power transmission shaft 8300 and the slider 8100. The power transmission shaft 8300 is fixedly connected to the fixed frame 8200 to receive a power source from the fixed frame 8200 or the robot arm, and the power source can be provided by a motor or a cylinder.

[0055] The slider 8100 includes a transmission shaft 8111 connected to the three-section coupling 8400, a sleeve 8112 covering the transmission shaft 8111, and a bearing assembly disposed between the transmission shaft and the sleeve. The sleeve 8112 is fixedly connected to the first sliding part 8110 so as to slide according to the surface profile of the carbon electrode 3000.

[0056] The bearing assembly includes a first annular bearing 8113 and a second annular bearing 8114 arranged in sequence along the X-axis. In addition, the bearing assembly may further include more annular bearings. The multiple annular bearings arranged in sequence along the X-axis may improve the stability of the tool kit 1000 in the radial direction of the main tool shaft.
