Description

Technical Field

[0001] The invention relates to the technical field of copper inlay polishing, in particular to a copper inlay polishing device with a cam mechanism. Background Art

[0002] Copper inserts are copper parts embedded in other materials (such as plastic, wood, etc.). They are usually used to enhance structural strength, improve conductivity or provide a firm connection point. The purpose of polishing copper inserts is to remove surface impurities and oxide layers to make them smoother, ensure better bonding when embedded in other materials, and prevent corrosion and wear. Common copper inserts include nut inserts, threaded inserts, hot-melt inserts and embedded terminals. These inserts are widely used in electronics, electrical appliances, machinery, construction and other fields, playing a key role in connection and fixing.

[0003] Some cylindrical copper inserts only need to be polished on the end face or the outer wall, such as bearing bushings, conductive copper sleeves, etc. However, the prior art lacks a device for simultaneously polishing the end face and outer wall of cylindrical copper inserts. In actual processing, the cylindrical copper inserts need to be transferred to different workstations, which increases the complexity of the operation and the time cost. Each transfer may introduce positioning errors, affecting the processing accuracy and consistency. In addition, frequent transfers and clamping increase equipment wear and manual labor intensity, resulting in increased production costs and extended production cycles. These shortcomings are particularly prominent in mass production, seriously affecting production efficiency and product quality. Summary of the invention

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The present invention provides an inner support assembly for fixing the cylindrical copper inlay on the common plate on the top of the workbench, and a composite grinding assembly is provided on the top of the side of the workbench. The composite grinding assembly can grind the outer wall and end face of the cylindrical copper inlay at the same time, which can completely solve the traditional need to transfer the cylindrical copper inlay to different workstations, increasing the complexity of operation and time cost.

The temporary support assembly can temporarily support the bottom of the cylindrical copper insert before the inner support assembly fixes the cylindrical copper insert. A space is left between the end surface of the bottom of the cylindrical copper insert and the workbench, so that the end surface of the bottom of the cylindrical copper insert is exposed, which is convenient for the composite grinding assembly to be inserted into the upper and lower end surface positions of the cylindrical copper insert.

[0019] 3. The present invention provides a composite cam assembly for controlling the movement of the composite grinding assembly and the temporary support assembly at the bottom of the workbench. The composite cam assembly can control the linkage movement of the composite grinding assembly and the temporary support assembly. When the composite cam assembly drives the composite grinding assembly to move to the grinding station, it can drive the temporary support assembly to move down to a position where it no longer supports the bottom of the cylindrical copper inlay, thereby preventing the temporary support assembly from being rubbed by the bottom of the cylindrical copper inlay when the cylindrical copper inlay is driven to rotate by the internal support assembly, causing wear.

[0020] 4. The present invention is provided with a driving motor, a driving gear, and a driven gear ring at the bottom of the inner support component, and a micro switch for controlling the driving motor is vertically arranged at the bottom of the workbench. When the inner support component is supporting and fixing the cylindrical copper inlay, and the composite cam component drives the composite grinding component to enter the grinding station, the micro switch can be triggered, and the driving motor automatically drives the cylindrical copper inlay on the inner support component to rotate automatically. The whole device has a high degree of automation, and the setting of the micro switch is interlocked with the composite cam component. Only when the composite grinding assembly is moved to the grinding station, the driving motor can rotate to drive the whole device to perform grinding work, saving a lot of electricity.

[0037] Reference Figure 1-13A copper inlay grinding equipment with a cam mechanism includes a workbench 2, a base 5 is fixedly arranged at the bottom of the workbench 2, a fixed cover 4 is vertically fixedly arranged on the top of the side of the workbench 2, a transparent cover 1 is rotatably connected to the top of the fixed cover 4, an intermediate plate 6 is fixedly arranged at the middle position of the inner cavity of the workbench 2, a center groove 10 is opened on the top of the workbench 2, a docking tube 26 is rotatably connected to the bottom of the center groove 10, a common plate 25 is fixedly arranged on the top of the docking tube 26, the weight of the base 5 is set larger, so that the whole workbench 2 remains stable, transparent acrylic plates are arranged on the transparent cover 1 and the fixed cover 4, which is convenient for observing the grinding status of the workpiece at the bottom of the transparent cover 1 and the fixed cover 4, and the transparent cover 1 can be turned down, and the transparent cover 1 and the fixed cover 4 form a protective cover for the whole grinding mechanism to avoid the waste generated during the grinding process from splashing everywhere, which may cause scalding accidents.

[0038] The common plate 25 is provided with an inner support assembly for clamping the cylindrical copper inlay when grinding. The inner support assembly includes an inner support rod 33, an extension column 36, a connecting spring 34, a mounting folding rod 32, a central cylinder 29, and a conical table 28. The four corners of the top of the common plate 25 are provided with transverse grooves 24. The side of the transverse groove 24 is fixedly connected to one end of the connecting spring 34. One end of the mounting folding rod 32 is fixedly connected to the bottom of the workbench 2. The other end of the connecting spring 34 is fixedly connected to the extension column 36. The extension column 36 is fixedly connected to the bottom of the workbench 2. An inner support rod 33 is fixedly provided on the top of the column 36, and the outer side surface of the inner support rod 33 is set to an arc surface, which can be fitted to the inner wall of the cylindrical copper insert to be fixed for internal support. A blocking block 35 is fixedly provided on the outer wall of the extension column 36. The width of the blocking block 35 is greater than the width of the transverse groove 24, and the width of the inner support rod 33 is greater than the width of the transverse groove 24. The blocking block 35 cooperates with the blocking block 35 to limit the transverse movement of the inner support rod 33 along the transverse groove 24. When the connecting spring 34 is at its original length, the four groups of inner support rods 33 are at the closest distance to each other.

[0039] A central cylinder 29 is vertically fixed at the other end of the installation folding rod 32, and a conical platform 28 is fixed at the output end of the central cylinder 29. The conical platform 28 extends between the four groups of extension columns 36. The conical platform 28 is a narrow upper and wide lower structure. When the central cylinder 29 is extended, it drives the conical platform 28 to move up to an appropriate position. The inner support rods 33 at the top of the four groups of extension columns 36 are at appropriate positions. The central cylinder 29 needs an external controller to accurately control the extension length of the central cylinder 29.

[0040] The four groups of extension columns 36 are arranged to form an arc surface 361 on the outer wall of the conical platform 28 to reduce the wear between the four groups of extension columns 36 and the conical platform 28 when they rotate. In order to further reduce the wear on the bottom ends of the four groups of extension columns 36, the extension columns 36 and the conical platform 28 are made of steel, stainless steel, cast iron and aluminum alloy, etc. The bottom of the extension columns 36 and the outer wall of the conical platform 28 are additionally plated with wear-resistant materials. The wear-resistant materials on the surface include hard chromium, nickel-phosphorus alloy, tungsten carbide, titanium nitride, chromium nitride, chromium carbide, silicon nitride and diamond-like coating, etc.

[0041] A grinding motor 31 is fixedly arranged at the bottom of the mounting folding rod 32, and a driving gear 30 is fixedly arranged at the output end of the grinding motor 31. The driving gear 30 is stably meshed with the driven gear ring 27, and the driven gear ring 27 is fixedly connected to the outer wall of the docking tube 26. The number of teeth of the driving gear 30 is much smaller than that of the driven gear ring 27, so that the grinding motor 31 can drive the inner support assembly to rotate slowly through the driving gear 30 and the driven gear ring 27, and finally drive the cylindrical copper insert to be polished to rotate slowly and cooperate with the composite grinding assembly to polish the outer wall and end face of the cylindrical copper insert.

[0042] An avoidance groove 3 is provided on the top of the workbench 2, and a composite grinding component for simultaneously grinding the end face and outer wall of the cylindrical copper insert is arranged inside the avoidance groove 3. A temporary support component is provided on one side of the composite grinding component on the top of the workbench 2 to facilitate the composite grinding component to extend into the two ends of the cylindrical copper insert. The composite grinding component includes a vertical grinding rod 18, a horizontal grinding rod 20, a common rod 21, and an intermediate rod 22. An extension rod 14 is vertically fixed at the bottom of the intermediate rod 22. The top of the intermediate rod 22 is threadedly connected to one end of the adjusting screw 23, and the other end of the adjusting screw 23 is rotatably connected to the side of the common rod 21. The common rod 21 is movably inserted into the side of the intermediate rod 22, so that the common rod 21 can slide and move laterally along the outer wall of the intermediate rod 22. The head of the adjusting screw 23 is provided with a corrugated head. When the adjusting screw 23 rotates, the two groups of horizontal grinding rods 20 can be driven by the common rod 21 to extend the end of the vertical grinding rod 18 to an appropriate length, so as to grind cylindrical copper inserts with different end face thicknesses.

[0043] Horizontal grinding rods 20 are fixedly provided at both ends of the common rod 21, vertical grinding rods 18 are fixedly provided at the end of the middle rod 22, horizontal T-rods 19 are movably inserted into the horizontal grinding rods 20, vertical T-rods 17 are movably inserted into the vertical grinding rods 18 along the vertical direction, and grinding sandpaper is inserted between the vertical grinding rods 18 and the vertical T-rods 17, and between the horizontal grinding rods 20 and the horizontal T-rods 19.

[0044] A gap equal to the thickness of the sandpaper is left between the vertical grinding rod 18 and the vertical T-rod 17 and between the horizontal grinding rod 20 and the horizontal T-rod 19. When the sandpaper is inserted into the gap between the vertical grinding rod 18 and the vertical T-rod 17 and between the horizontal grinding rod 20 and the horizontal T-rod 19, the sandpaper presents a convex shape, and both ends of the sandpaper are fixed by the vertical grinding rod 18 and the vertical T-rod 17 and between the horizontal grinding rod 20 and the horizontal T-rod 19. The sandpaper on the side of the raised part of the vertical T-rod 17 and the raised part of the horizontal T-rod 19 is the actual grinding section of the sandpaper.

[0045] The existence of the vertical T-bar 17 and the horizontal T-bar 19 facilitates the instant replacement of sandpaper of different mesh sizes by the horizontal grinding rod 20 and the vertical grinding rod 18 to meet the roughness requirements of the outer wall and end face of the cylindrical copper insert. Furthermore, the horizontal grinding rod 20 is arranged in an arc shape near one end of the cylindrical copper insert and fits to both ends of the cylindrical copper insert.

[0046] The extension rod 14 extends from the avoidance groove 3, and the extension rod 14 is fixedly provided with limit blocks 15 on the upper and lower sides of the avoidance groove 3. The width of the limit blocks 15 is greater than the width of the avoidance groove 3. The limit blocks 15 assist the extension rod 14 to stably move laterally along the avoidance groove 3. The bottom of the extension rod 14 is rotatably connected to one end of the driving rod 16, and the other end of the driving rod 16 is provided with a composite cam assembly for controlling the actions of the composite grinding assembly and the temporary support assembly. The composite cam assembly includes a servo motor 7, a center column 11, an auxiliary support disk 12, and an intermediate disk 13. The servo motor 7 is vertically fixed on the intermediate plate 6, and the intermediate disk 13 is fixedly provided at the output end of the servo motor 7. The auxiliary support disk 12 is fixedly provided on the top of the intermediate disk 13. The top of the auxiliary support disk 12 is set to an inclined surface, and the appearance of the auxiliary support disk 12 is an end face cam structure.

[0047] A center column 11 is fixedly arranged on the top of the auxiliary support disk 12. The diameter of the center column 11 is smaller than the diameter of the auxiliary support disk 12, and the height of the center column 11 is greater than the height of the auxiliary support disk 12. The servo motor 7 requires an external controller, and the servo motor 7 requires an external controller to set the required specific angle, so that when the servo motor 7 drives the center column 11, the auxiliary support disk 12, and the integrated structure of the center column 11 to rotate, the corresponding auxiliary support components and the composite grinding components can work together to enter the preset work station.

[0048] The non-center part of the top of the center column 11 is rotatably connected to one end of the driving rod 16. When the center column 11 rotates, it forms a "crank slider structure" with the driving rod 16 and the composite grinding assembly. After the center column 11 rotates to a specific angle, the composite grinding assembly is pulled to the grinding station by the driving rod 16.

[0049] The temporary support assembly includes a temporary support fork 37, a connecting bent rod 38, a reset spring 39, and a lifting column 41. A connecting bent rod 38 is fixedly provided on the side of the temporary support fork 37, and a lifting column 41 is fixedly provided at the bottom of the connecting bent rod 38. The lifting column 41 is movably inserted into the workbench 2, and the bottom of the lifting column 41 is abutted against the top of the auxiliary support plate 12. A connecting ring 40 is fixedly provided on the outer wall of the lifting column 41. The outer wall of the connecting ring 40 is fixedly connected to one end of the reset spring 39, and the other end of the reset spring 39 is fixedly connected to the bottom of the workbench 2. When the auxiliary support plate 12 rotates to a certain angle, the lifting column 41 is pushed up. At this time, the reset spring 39 is compressed, and the lifting column 41 drives the temporary support fork 37 to move up to the temporary support position.

[0050] A vertical plate 8 is vertically fixedly arranged at the bottom side of the avoidance groove 3 on the workbench 2, and a micro switch 9 is vertically fixedly arranged at the bottom of the side of the vertical plate 8. The micro switch 9 is connected to the control circuit of the grinding motor 31.

[0051] The specific implementation steps and principles of the present invention are as follows:

[0052] In the initial state, the temporary support fork 37 is at the highest position under the support of the auxiliary support plate 12. At this time, the horizontal grinding rod 20 and the vertical grinding rod 18 are at the farthest distance from the inner support assembly, and the reset spring 39 is compressed. The worker sets the cylindrical copper inlay on the outer wall of the multiple groups of inner support rods 33 until the bottom of the cylindrical copper inlay overlaps the top of the temporary support fork 37, starts the central cylinder 29, and the central cylinder 29 extends out, driving the multiple groups of inner support rods 33 away from each other through the conical platform 28, thereby fixing the cylindrical copper inlay for inner support, and then starts the servo motor 7, which drives the central column 11, the auxiliary support plate 12, and the intermediate plate 13 to rotate the set angle. In this process, the auxiliary support plate 12 and the intermediate plate 13 are rotated to the set angle. The support plate 12 rotates to a position where it no longer pushes up the temporary support fork 37, and the reset spring 39 drives the temporary support fork 37 to move down to a position where it no longer supports the bottom of the cylindrical copper insert. On the other hand, the center column 11 drives the extension rod 14 through the drive rod 16 to approach the three groups of inner support rods 33 along the avoidance groove 3. At this time, the two groups of horizontal grinding rods 20 extend into the upper and lower end surfaces of the cylindrical insert. At this time, the extension rod 14 triggers the microswitch 9, and the microswitch 9 controls the grinding motor 31 to start. The grinding motor 31 rotates through the driving gear 30 and the driven gear ring 27, and the inner support assembly drives the cylindrical copper insert to rotate. The sandpaper on the horizontal grinding rod 20 and the vertical grinding rod 18 can grind the cylindrical copper insert.

[0053] After the cylindrical copper inlay is polished, the servo motor 7 drives the center column 11, the auxiliary support plate 12, and the intermediate plate 13 to rotate in the opposite direction to the set angle. During this process, the auxiliary support plate 12 rotates to the position of the upper temporary support fork 37, driving the temporary support fork 37 to move up to the position supporting the bottom of the cylindrical copper inlay. On the other hand, the center column 11 drives the extension rod 14 along the avoidance groove 3 away from the three groups of inner support rods 33 through the driving rod 16. At this time, the two groups of horizontal grinding rods 20 are detached from the upper and lower end surfaces of the cylindrical copper inlay, and the extension rod 14 does not trigger the microswitch 9. The microswitch 9 controls the polishing motor 31 to stop. After waiting for a certain period of time, the inner support assembly stops, and finally the center cylinder 29 is started to retract. The conical table 28 no longer expands the multiple groups of inner support rods 33. The multiple groups of inner support rods 33 no longer expand the cylindrical copper inlay under the reset of the connecting spring 34. Finally, the worker removes the cylindrical copper inlay from the three groups of inner support rods 33.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
