Description

Technical Field

[0001] This utility model relates to a copper roller grinding device. Background Technology

[0002] In the production process of hydrogen storage alloy powder, the raw materials are melted in a smelting furnace and then rapidly cooled by rotating copper rollers to become flake alloy powder. During the production process, as the molten metal continuously flows and cools rapidly on the copper rollers, after a certain period of time, slight cracks and uneven surface defects appear on the surface of the copper rollers. These defects cause the surface runout to exceed the process requirements when the copper rollers rotate, which in turn causes an excessive gap in the tundish that is in close contact with the copper rollers during smelting. During smelting and pouring, molten liquid flows from the gaps into the equipment, melting the copper wire used to detect leakage alarms and preventing automatic pouring. This causes equipment failure and malfunction. Therefore, in order to avoid the above problems, it is necessary to grind and repair the copper rollers when slight cracks and uneven defects appear. The traditional method for polishing copper rollers involves removing the rollers and machining them on a lathe to achieve a smooth surface, thus restoring the round runout to meet the process requirements. However, this method is inconvenient to operate, and due to machining and clamping errors, the repaired copper rollers sometimes fail to meet the process requirements and cannot be used again. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model aims to provide a copper roller grinding device that is simple in structure, easy to use, and has high grinding and repair precision.

[0004] This utility model is achieved through the following solution:

[0005] A copper roller grinding device includes a moving assembly and a feed assembly. The moving assembly includes a motor mounting plate, a motor, a moving lead screw, a feed assembly mounting plate, and two moving lead screw support plates. The two moving lead screw support plates are vertically arranged on the top of the motor mounting plate in a parallel manner. The moving lead screw is straddling the two moving lead screw support plates and is rotatable. The feed assembly mounting plate is fitted onto the moving lead screw and can move along the moving lead screw as it rotates. The motor is mounted on the motor mounting plate, and the motor shaft is connected to one end of the moving lead screw. The feed assembly includes a connecting plate, a feed lead screw, a nut, a nut mounting plate, a cutting tool placement plate, a cutting tool, a cutting tool clamping plate, and a dial indicator. Feed lead screw support plates are vertically arranged at both ends of the connecting plate, and the feed lead screw is straddling the two feed lead screw support plates. The feed screw is rotatable, and the nut is fitted onto the feed screw and can move along the feed screw as it rotates. The top of the nut is fixed to the bottom of the nut fixing plate, and the bottom of the cutting tool placement plate is fixed to the top of the nut fixing plate. The cutting tool placement plate is located above the feed screw support plate. The cutting tool is placed on the cutting tool placement plate, and the cutting tool tip extends out of one end of the cutting tool placement plate. A cutting tool clamping plate support sleeve is provided on the top of the cutting tool placement plate. The cutting tool clamping plate is installed on the cutting tool clamping plate support sleeve and fixed to the cutting tool placement plate. The cutting tool clamping plate tightly presses against the cutting tool tail end. The dial indicator is installed on one side of the cutting tool placement plate, and the dial indicator probe is flush with the cutting tool tip end face. The connecting plate of the feed assembly is fixed to the motor fixing plate of the moving assembly, and the feed screw of the feed assembly is spatially perpendicular to the moving screw of the moving assembly.

[0006] Furthermore, the connecting plate of the feed assembly is positioned between the two feed screw support plates and is equipped with at least one guide rail perpendicular to the feed screw support plates. A slider is mounted on the guide rail and can move along it. The top of the slider is fixed to the bottom of the nut fixing plate. The guide rail and slider configuration ensure that the nut's movement trajectory does not deviate, thereby ensuring accurate tool feed.

[0007] Furthermore, the dial indicator is mounted on one side of the cutting tool placement plate via an L-shaped dial indicator fixing device. Specifically, the vertical part of the dial indicator fixing device is mounted on one side of the cutting tool placement plate, and the dial indicator is mounted on the horizontal part of the dial indicator fixing device, with the dial indicator probe passing through the horizontal part of the dial indicator fixing device.

[0008] Furthermore, a rotary handwheel is installed at the end of the feed screw away from the cutting tool head. The rotary handwheel facilitates the rotation operation of the feed screw.

[0009] Furthermore, a spring is provided between the end face of the nut fixing plate near the tool head and the inward-facing surface of the feed screw support plate near the tool head. The spring eliminates the gap between the feed screw and the nut, ensuring accurate tool feed.

[0010] Furthermore, at least one guide rod is straddled between the two movable lead screw support plates, and the feed assembly fixing plate is fitted onto the guide rod and can move along the guide rod. The number of guide posts can be adjusted as needed. The guide posts ensure that the feed assembly fixing plate does not swing when moving along the movable lead screw, ensuring that the feed assembly fixing plate moves with the feed assembly to the set position.

[0011] Furthermore, a drive sprocket is mounted on the motor shaft of the motor, and a driven sprocket is provided on the end of the moving screw near the motor. The drive sprocket is connected to the driven sprocket via a chain to connect the motor shaft of the motor to one end of the moving screw.

[0012] When using the copper roller grinding device, it can be directly fixed to the worktable by the motor fixing plate. Alternatively, depending on the site conditions, a fixing device can be set on the side or end face of the motor fixing plate of the copper roller grinding device. The fixing device can be fixed to the corresponding fixing component. The position and shape of the fixing device can be adjusted appropriately according to the structure and shape of the corresponding fixing component. For example, if the fixing component is a column structure, the fixing device can be set as a cylindrical clamping structure.

[0013] The copper roller grinding device of this utility model has a simple structure and is easy to use. It can grind and repair copper rollers without removing them. The grinding and repair precision is high, which can ensure that the circular runout of the copper roller after grinding and repair meets the process requirements. This allows the ground and repaired copper roller to be put back into use and extends the service life of the copper roller. At the same time, it can save the process of disassembling the copper roller, save related disassembly costs, and improve work efficiency. Attached Figure Description

Two guide rails 210 perpendicular to the feed screw support plates 209 are arranged on the connecting plate 201 between the two feed screw support plates 209. On both sides of the feed screw 202, sliders 211 are provided on the guide rail 210 and can move along the guide rail 210. Nuts 203 are fitted on the feed screw 202 and can move along the feed screw 202 as the feed screw 202 rotates. The top of the nut 203 and the top of the slider 211 are fixed to the bottom of the nut fixing plate 204. The bottom of the cutting tool placement plate 205 is fixed to the top of the nut fixing plate 204 and the cutting tool placement plate 205 is located above the feed screw support plate 209. The cutting tool 206 is placed on the cutting tool placement plate 205 and the tip of the cutting tool 206 extends out of the cutting tool. At one end of the tool placement plate 205, a tool clamping plate support sleeve 212 is provided on the top of the tool placement plate 205. The tool clamping plate 207 is bolted to the tool clamping plate support sleeve 212 and fixed to the tool placement plate 205. The tool clamping plate 207 presses the tail end of the tool 206 tightly with bolts. A spring 213 is provided between the end face of the nut fixing plate 204 near the head end of the tool 206 and the inward face of the feed screw support plate 209 near the head end of the tool 206. A dial indicator 208 is mounted on one side of the tool placement plate 205 through an L-shaped dial indicator fixing device 214. The probe of the dial indicator 208 is flush with the end face of the cutting tool 206. Specifically, the vertical part of the dial indicator fixing device 214 is installed on one side of the cutting tool placement plate 205, the dial indicator 208 is installed on the horizontal part of the dial indicator fixing device 214 and the probe of the dial indicator 208 passes through the horizontal part of the dial indicator fixing device 214, and a rotating handwheel 215 is installed at the end of the feed screw 202 away from the end of the cutting tool 206; the connecting plate 201 of the feed assembly 2 is fixed on the motor fixing plate 11 of the moving assembly 1 and the feed screw 202 of the feed assembly 2 is spatially perpendicular to the moving screw 13 of the moving assembly 1.

[0021] In use, the copper roller grinding device 0 is fixed to the fixed part near the copper roller 3 to be ground and repaired via the fixing device on the motor fixing plate of the moving component. Ensure that the moving lead screw is parallel to the copper roller to be ground and repaired, and that the cutting tool head faces the copper roller to be ground and repaired. Simultaneously, ensure that the cutting tool is positioned close to the head end of the copper roller to be ground and repaired. A schematic diagram of the positions of the copper roller grinding device 0 and the copper roller 3 to be ground and repaired is shown below. Figure 4As shown. In actual operation, the motor is started and rotated clockwise. The drive sprocket on the motor shaft rotates, causing the driven sprocket to rotate, which in turn rotates the moving lead screw. This drives the feed assembly fixing plate to move away from the motor, i.e., towards the tail end of the copper roller to be ground and repaired. When the cutting tool moves to the position directly opposite the tail end of the copper roller to be ground and repaired, the motor stops. At this point, the copper roller motor is started, causing the copper roller to rotate. Simultaneously, the handwheel is rotated clockwise, causing the feed lead screw to rotate... This movement causes the nut to move closer to the copper roller to be ground and repaired. When the cutting tool tip contacts the surface of the copper roller, continue rotating the handwheel clockwise to allow the cutting tool tip to advance a certain distance. Then, hold the handwheel still. The cutting tool can then begin grinding and repairing the surface of the copper roller. Simultaneously, start the motor and rotate it counterclockwise, causing the feed assembly fixing plate to move closer to the motor, i.e., towards the head end of the copper roller to be ground and repaired. This allows the cutting tool to move from the tail end to the head end of the copper roller to be ground and repaired. The entire surface of the head end is ground and repaired. While the cutting tool is working, observe the dial indicator readings to determine if the ground and repaired surface of the copper roller meets the process requirements. If not, adjust the cutting depth of the cutting tool by turning the handwheel to ensure the surface meets the requirements. When the cutting tool leaves the head end surface of the copper roller, stop the motor and simultaneously rotate the handwheel counter-clockwise to return the cutting tool to its original position. Observe the grinding and repair process of the copper roller. The surface finish is then assessed, and the change in dial gauge readings during processing is used to determine whether the above steps need to be repeated for another grinding and repair of the copper roller. If no further grinding and repair is needed, the circular runout at both ends of the copper roller is checked. If the circular runout of the copper roller meets the process requirements, the copper roller grinding device is removed, thus completing the grinding and repair work of the copper roller to be ground and repaired. If the circular runout of the copper roller does not meet the process requirements, the above steps are repeated for another grinding and repair until the circular runout of the copper roller meets the process requirements.
