Description

Technical Field

[0001] This invention relates to the technical field of metal grinding and processing. More specifically, this invention relates to a copper rod grinding and processing apparatus and method with rapid positioning capability. Background Technology

[0002] In the polishing and grinding process of copper rods, existing grinding devices typically use grinding wheels to achieve dual functions in order to simplify the structure and reduce costs: on the one hand, they grind the surface of the copper rod, and on the other hand, by setting the grinding wheel to be axially offset, they drive the copper rod to move horizontally along its axial direction while rotating.

[0003] However, to achieve effective positioning of the copper rod, existing technologies typically place limiting plates on both sides of the copper rod, and these limiting plates need to contact the copper rod to ensure its stable running trajectory. While this contact helps with positioning, significant frictional resistance is generated between the limiting plates and the copper rod during its movement, affecting its smooth movement, thus interfering with the grinding process, reducing grinding efficiency, and even affecting processing quality.

[0004] In summary, this application proposes a copper rod grinding processing device and method with rapid positioning capability, which improves the technical problems mentioned above. Summary of the Invention

Start the motor, which drives the grinding wheels to rotate. Manually push the copper rod to the right, so that the right end of the copper rod moves into the gap between the two grinding wheels and makes contact with the grinding wheels. The grinding wheels grind the copper rod and drive the copper rod to rotate and move to the right.

[0016] Beneficial effects: First, the copper rod drives the long rod to rotate through friction, which helps to reduce the frictional resistance in the direction of rotation of the copper rod. Compared with conventional plate positioning, it can effectively reduce the resistance encountered by the copper rod during movement, avoiding the problem of poor movement due to excessive resistance, thus avoiding interference with the grinding operation. Second, by combining the outer shell with the suction air, impurities generated during grinding are intercepted, effectively preventing impurities from splashing and remaining in the gaps of the long rod, thus avoiding interference with its rotation and the grinding operation. At the same time, the hollow column, together with the long rod, limits the copper rod, effectively preventing the copper rod from shifting and interfering with the grinding operation. In addition, the hollow column used to limit the copper rod can also be used with a spring to adjust the frictional resistance on the copper rod, avoiding uneven grinding caused by reduced frictional resistance in the initial stage of grinding. Furthermore, the hollow column used to limit the copper rod can also be used to blow away impurities remaining on the surface of the copper rod, preventing impurities from damaging the copper rod. Third, the hollow column can be quickly disassembled by the combination of protrusions, groove one, groove two and elastic beads, which is very convenient. At the same time, the angle of the long rod, the height of the long rod and the distance between the two grinding wheels can be adjusted by the combination of screw, telescopic cylinder and lead screw, so as to adapt to the grinding operation of copper rods of different diameters, which is highly versatile.

The external suction pipe draws air from the pipe 202 to remove the impurities dispersed inside the housing 201; a mechanical swing arm is installed inside the housing 201 to push the end of the copper rod out from inside the housing 201.

[0023] Each hollow column 302 has several ventilation holes; each hollow rod 301 is connected to the corresponding hollow column 302.

[0024] It also includes auxiliary components, including a connecting block 205 and a spring 206; each electric push rod 203 has a connecting block 205 fixedly connected to its telescopic end, the connecting block 205 is slidably connected to the outer shell 201, and the connecting block 205 is connected to the corresponding connecting seat 204; each connecting block 205 has two springs 206 fixedly connected to it, the springs 206 are connected to the corresponding connecting seat 204, and the springs 206 are made of metal.

[0025] It also includes a quick-release assembly, which includes a second connecting block 207 and elastic beads 208; each first connecting block 205 is slidably connected to a second connecting block 207, the second connecting block 207 is plugged into and pulled into a corresponding connecting seat 204, and the second connecting block 207 is fixedly connected to a corresponding spring 206; each second connecting block 207 is fixedly connected to two elastic beads 208; each connecting seat 204 is provided with a protrusion 91; each connecting seat 204 is provided with two first grooves 92; each second connecting block 207 is provided with a second groove 93; the movable part of the elastic bead 208 is located in the corresponding first groove 92, and the connecting seat 204 is fixed by the elastic bead 208; the protrusion 91 is located in the corresponding second groove 93.

[0026] First, the external vacuum hose is manually connected to pipe 202. The copper rod is then moved to the upper left side of the receiving plate 4 and lowered so that it rests on the symmetrical long rods 7. At this point, the long rods 7 not only position the height of the copper rod but also its front-to-back direction, aligning the axis of the copper rod with the middle of the gap between the two grinding wheels 3. Then, the motor 2 is started, driving the grinding wheels 3 to rotate. The copper rod is manually pushed to the right, moving its right end to the gap between the two grinding wheels 3 and into contact with them. Since the grinding wheels 3 are frustum-shaped, the frictional force exerted by the grinding wheels 3 on the copper rod can be decomposed into tangential forces. The copper rod is rotated via the tangential component and moved to the right via the axial component. This causes the copper rod to rotate while simultaneously moving to the right, meaning it passes through the gap between the two grinding wheels 3 in a rotating posture. During this process, the grinding wheels 3 polish the outer surface of the copper rod. As the copper rod rotates, friction causes the long rod 7 to rotate, which helps reduce the frictional resistance in the rotational direction. Compared to conventional long-plate positioning, this effectively reduces the resistance encountered during the copper rod's movement, preventing problems caused by excessive resistance and thus avoiding interference with the polishing operation.

[0027] Impurities generated during the polishing of the copper rod splash onto the long rod 7 and become stuck in the gaps between adjacent long rods 7, interfering with the rotation of the long rod 7. This reduces the ability of the long rod 7 to reduce the resistance on the copper rod. Therefore, a housing 201 is installed on the outside of the two polishing wheels 3 to intercept most of the impurities generated during polishing. At the same time, air is drawn into the pipe 202 through the external suction pipe, allowing outside air to flow into the inside of the housing 201 through the through hole 90, then into the pipe 202, and finally into the external suction pipe, thereby removing impurities. The impurities generated during polishing are completely removed. During this process, outside air continuously flows into the inner side of the outer casing 201 through the through hole 90. After the copper rod passes through the through hole 90, the airflow channel at this point is reduced, which helps to increase the airflow speed. This forms an air barrier in the through hole 90, preventing impurities from spreading outward from the through hole 90. This effectively avoids impurities splashing and remaining in the gaps of the long rod 7. In use, the outer casing 201 and the suction air work together to intercept the impurities generated during polishing. This effectively avoids the problem of impurities splashing and remaining in the gaps of the long rod 7 and interfering with its rotation, thus avoiding interference with the polishing operation.

[0028] During the polishing process of the copper rod, in order to ensure the uniformity of polishing, the copper rod should always be aligned with the middle of the gap between the two polishing wheels 3. However, the long rod 7 can only limit the front, back, and bottom sides of the copper rod. When the copper rod is subjected to external forces such as vibration, it will jump upwards, causing the long rod 7 to deviate from the middle of the gap between the two polishing wheels 3, thereby reducing the uniformity of polishing. Therefore, a limiting component is set on the outer shell 201. When the end of the copper rod passes through the through hole 90, the electric push rod 203 drives the connecting seat 204 to move. The connecting seat 204 drives the hollow rod 301 and the hollow column 302 to move, so that the hollow column 302 contacts the copper rod. The hollow column 302 limits the movement of the copper rod, preventing it from shifting upwards and jumping. During the movement of the copper rod, the hollow column 302 has a protective layer on its surface, and the hardness of the protective layer is lower than that of the copper rod, so the hollow column 302 will not scratch the copper rod. At the same time, during the movement of the copper rod, the copper rod drives the hollow column 302 and the hollow rod 301 to rotate through friction, converting sliding friction into rolling friction, further avoiding scratches. In use, the hollow column 302 works in conjunction with the long rod 7 to limit the movement of the copper rod, effectively preventing the copper rod from shifting and thus avoiding interference with the polishing operation of the copper rod.

[0029] In the initial stage of polishing, the right end of the copper rod passes through the left through hole 90, but before it passes through the right through hole 90 onto the right long rod 7, the contact area between the copper rod and the left long rod 7 continuously decreases. This leads to a decrease in the frictional resistance experienced by the copper rod, causing instability in its movement speed and affecting the uniformity of polishing. Therefore, the electric push rod 203 drives the connecting block 1 205 and its components to move towards the copper rod. Because the hollow column 302 is blocked by the copper rod, the connecting block 1 205 slides relative to the connecting block 2 207, and the spring 20... When compressed, spring 206 applies elastic force to connecting seat 204, thereby pressing hollow column 302 against copper rod, thus increasing the pressure of hollow column 302 on copper rod, thereby adjusting the friction between copper rod and hollow column 302, so that the total frictional resistance on copper rod remains stable, thus enabling copper rod to be polished evenly. In use, hollow column 302, which is used to limit copper rod, can also work with spring 206 to adjust the frictional resistance on copper rod, avoiding the problem of uneven polishing caused by the reduction of frictional resistance on copper rod in the initial stage of polishing.

[0030] During the polishing process, some impurities remain on the surface of the copper rod. The hollow column 302 will squeeze these impurities onto the surface of the copper rod, resulting in pressure damage. Therefore, ventilation holes are made on the hollow column 302. First, an external air inlet pipe is manually connected to the hollow rod 301. During polishing, air is supplied to the hollow rod 301 through the external air inlet pipe. The air flows into the inside of the hollow column 302 through the hollow rod 301 and then sprays out from the ventilation holes, thereby blowing away the impurities remaining on the surface of the copper rod and effectively avoiding pressure damage. In use, the hollow column 302, which is used to limit the copper rod, can also be used to blow away impurities remaining on the surface of the copper rod, preventing the problem of impurities damaging the copper rod.

[0031] During the polishing process, the hollow column 302 and the copper rod will slide relative to each other. Over time, the protective layer on the surface of the hollow column 302 will wear down. Therefore, the hollow column 302 needs to be replaced regularly. When replacing, the connecting seat 204 is manually moved. The connecting seat 204 squeezes the movable part of the elastic ball 208, making it move away from the groove 92. This causes the protrusion 91 to fall out of the groove 93, quickly completing the disassembly operation. Then, the new connecting seat 204 is inserted back into the connecting block 207, quickly completing the replacement operation. During the polishing process, the resistance experienced by the connecting seat 204 is towards the side away from the protrusion 91, that is, the connecting seat 204 will not fall off due to friction. In use, the hollow column 302 can achieve quick disassembly through the cooperation of the protrusion 91, the groove 92, the groove 93 and the elastic ball 208, which is very convenient.

[0032] Example 2, based on Example 1, such as Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, it also includes an adjustment assembly, which includes a screw 209, a first adjustment unit, and a second adjustment unit; each limiting plate 5 is rotatably connected to the receiving plate 4; each limiting plate 5 is provided with a screw 209, which is screwed to the receiving plate 4; the first adjustment unit is connected to the worktable 1; and the second adjustment unit is connected to the outer shell 201.

[0033] The first control unit includes a connecting block 3 2010, a connecting block 4 2011, a telescopic cylinder 2012, and a stop block 2013. The connecting block 3 2010 is bolted to the worktable 1. Two connecting blocks 4 2011 are slidably connected to the connecting block 3 2010, and the connecting blocks 4 2011 are bolted to the corresponding motor 2. Two telescopic cylinders 2012 are bolted to the connecting block 3 2010, and the telescopic ends of the telescopic cylinders 2012 are fixedly connected to the corresponding connecting blocks 4 2011. Two stop blocks 2013 are slidably connected to the outer shell 201, and the stop blocks 2013 are rotatably connected to the corresponding output shaft of the motor 2. The stop blocks 2013 cover the holes of the outer shell 201 corresponding to the output shaft of the motor 2 to prevent dust from spreading out of the holes.

[0034] The second control unit includes a connecting block 5 2014, a lead screw 2015, and a connecting block 6 2016; two connecting blocks 5 2014 are bolted to the worktable 1; a lead screw 2015 is screwed onto each connecting block 5 2014; a connecting block 6 2016 is rotatably connected to each lead screw 2015; the connecting block 6 2016 is slidably connected to the worktable 1 and bolted to the receiving plate 4.

[0035] Depending on the diameter of the copper rod, the screw 209 is manually turned to stop pressing the limiting plate 5, thus rotating the limiting plate 5 and adjusting it to an appropriate angle. The limiting plate 5 adjusts the angle of the long rod 7, ensuring the copper rod is always supported on it. Simultaneously, the lead screw 2015 is manually turned, causing it to rotate on the connecting block 5 2014 while moving vertically. The lead screw 2015 drives the connecting block 6 2016 to move vertically, which in turn drives the supporting plate 4 and its components to move vertically, thereby adjusting the height of the long rod 7. This ensures that after the copper rod is supported on the long rod 7, its axis is always aligned with the center of the gap between the two grinding wheels 3. When in use, the telescopic cylinder 2012 drives the connecting block four 2011 to move on the connecting block three 2010. The connecting block four 2011 drives the motor 2 and the grinding wheel 3 to move, thereby adjusting the distance between the two grinding wheels 3 to accommodate the grinding operation of copper rods of different diameters. The motor 2 drives the stop block 2013 to move, so that after adjusting the position of the motor 2, the stop block 2013 can always cover the hole of the outer shell 201 corresponding to the output shaft of the motor 2, preventing dust from spreading out of the hole. In use, the screw 209, the telescopic cylinder 2012 and the lead screw 2015 can cooperate to adjust the angle of the long rod 7, the height of the long rod 7 and the distance between the two grinding wheels 3, thereby accommodating the grinding operation of copper rods of different diameters, and has strong versatility.

[0036] A method for quickly positioning and polishing copper rods includes the following steps: Step 1, handling: The copper rod to be polished is manually moved to the top of the receiving plate 4; Step 2: Placement. Manually move the copper rod downwards so that it rests on two symmetrical long sticks 7. Step 3, Grinding: Start motor 2, which drives the grinding wheel 3 to rotate. Manually push the copper rod to the right, so that the right end of the copper rod moves into the gap between the two grinding wheels 3 and comes into contact with the grinding wheels 3. The grinding wheels 3 grind the copper rod and drive the copper rod to rotate and move to the right.
