Description
Technical Field
[0001] The utility model belongs to the technical field of production of power distribution cabinets and relates to a grinding auxiliary mechanism for copper bars of the power distribution cabinet. Background Art
[0002] Distribution cabinets (boxes) are classified as power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final stage of the power distribution system. A distribution cabinet is a general term for motor control centers (MCCs). Distribution cabinets are used in applications with relatively dispersed loads and a small number of circuits, while MCCs are used in applications with concentrated loads and a large number of circuits. They distribute power from a circuit in the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the loads.
[0003] The power distribution cabinet mainly includes a cabinet body, copper busbars, and various electrical components. The copper busbars serve to connect the various electrical components. During the production process, the copper busbar is usually in the form of a long sheet, which is then cut, bent, punched, etc. as needed. The edges of the copper busbar also need to be polished to prevent cuts on workers or insulation sleeves. Currently, when polishing, workers usually hold a sander in one hand and hold the copper busbar with the other hand and flip the copper busbar according to the polishing area. If the copper busbar is small and straight, flipping the copper busbar is relatively easy. However, if it is a large or irregularly shaped copper busbar, it is difficult to flip or hold it with one hand, which is more difficult to operate. Utility Model Content

[0040] A stabilizing disk 6 is horizontally disposed at the bottom of the compression column 5 , and the diameter of the stabilizing disk 6 is larger than the diameter of the compression column 5 .
[0041] A first elastic member 7 is vertically provided on the top of each of the compression columns 5, and an integral rod 8 is horizontally provided between the tops of the two first elastic members 7. The first elastic member 7 is fixedly connected to the integral rod 8 and the compression column 5;
[0042] The second driving mechanism includes a driving frame 9 arranged on the side of the support frame 1, and the driving frame 9 is U-shaped with its opening facing the copper busbar. A driving cylinder 10 is vertically arranged on the top of the driving frame 9, and the piston rod of the driving cylinder 10 is fixedly connected to the middle part of the integrated rod 8.
[0043] A stabilizing arm 11 is horizontally provided on the top of the driving frame 9 , and two stabilizing rods 12 are vertically provided on the top of the integrated rod 8 . Both stabilizing rods 12 are movable through the stabilizing arm 11 , and the outer walls of the stabilizing rods 12 are movably fitted to the stabilizing arm 11 .
[0044] The second driving mechanism includes a driving cylinder 13, the top of which is fixedly connected to the bottom of the integrated rod 8, the first elastic member 7 is located in the driving cylinder 13, and the top outer wall of the pressing column 5 is movably attached to the inner wall of the driving cylinder 13;
[0045] A U-shaped linkage frame 14 is provided on the side of the lifting block 3, and the opening of the linkage frame 14 faces the copper bar. The compression column 5 moves through the linkage frame 14, and the outer wall of the compression column 5 is separated from the linkage frame 14. A reset plate 15 is provided on the outside of the support frame 1, and a second elastic member 16 that is continuously in a compressed state is provided between the top of the reset plate 15 and the bottom of the lifting block 3;
[0046] The driving cylinder 13 includes a first state, a second state and a third state;
[0047] When the driving cylinder 13 is in the first state, the top of the driving cylinder 13 is higher than the linkage frame 14, the stabilizing plate 6 is higher than the copper busbar, and the bottom of the supporting block 2 contacts the lifting block 3;
[0048] When the driving cylinder 13 is in the second state, the stabilizing plate 6 contacts the top of the copper busbar, and the driving cylinder 13 is higher than the linkage frame 14;
[0049] When the driving cylinder 13 is in the third state, it contacts the top of the linkage frame 14 and presses it downward. The stop block 4 is lower than the copper busbar, and the support block 2 and the stabilizing plate 6 are each at a set distance from the edge of the copper busbar. The reset plate 15 is rectangular, and the second elastic members 16 are provided at each of its four corners.
[0050] The lifting block 3 is provided with a dovetail bar 17 vertically on the side thereof, and the outer side of the support frame 1 is provided with a dovetail slot 18 vertically arranged to flexibly cooperate with the dovetail bar 17, so that the lifting block 3 can be stably raised and lowered on the support frame 1. The linkage frame 14 and the driving frame 9 are located on the same side of the copper busbar.
[0051] An adjustment plate 19 is horizontally provided on the side of the lifting block 3, and several pairs of adjustment holes 20 are opened on the adjustment plate 19. Two adjustment bolts 21 are movably provided through the end block 4. The adjustment bolts 21 can be threadedly connected with any pair of the adjustment holes 20, and when the adjustment bolts 21 are connected with different pairs of the adjustment holes 20, there is a difference in the distance between the side of the end block 4 and the support block 2.
[0052] The present invention provides a grinding auxiliary mechanism for the copper busbar of a distribution cabinet, wherein during the actual grinding process, if the copper busbar is very small, it can be flipped with one hand, but if the copper busbar is larger, the mechanism of the present application needs to be used for auxiliary grinding; at the same time, even if most copper busbars have certain special shapes, there is usually a part that is straight, such as the copper busbar in the attached figure, which has bent parts at both ends but a straight middle part, which can be used for clamping and positioning; secondly, the auxiliary mechanism of the present application is only used to fix and clamp the copper busbar, and the actual grinding operation still requires workers to manually use an angle grinder to grind the edge of the copper busbar.
[0053] During polishing, the worker first uses both hands to place the copper bar horizontally on the top of the supporting block 2 and the lifting block 3, and makes the side of the copper bar touch the end block 4; then the second driving mechanism drives the clamping column 5 downward, and the copper bar is clamped by the clamping column 5 and the supporting block 2; then the first driving mechanism drives the lifting block 3 downward, not only the lifting block 3 is lower than the copper bar, but also the lifting block 3 releases the edge of the copper bar, so that there is no obstruction structure around the copper bar and the upper and lower sides and outer sides of both ends, so that the subsequent polishing can be carried out smoothly and comprehensively, which not only saves labor but also ensures that every place is polished with high quality, that is, it reduces the difficulty of operation and ensures the quality of operation.
[0054] During actual operation, when the copper busbar is placed properly, the piston rod of the driving cylinder 10 (preferably a pneumatic cylinder, and an oil cylinder or an electric push rod can also be selected according to actual conditions) drives the integrated rod 8 downward to move. The integrated rod 8 first lowers the height of the clamping column 5 through the first elastic member 7 until the clamping column 5 is pressed against the top of the copper busbar through the stabilizing plate 6. At this time, the driving cylinder 13 has not yet contacted the linkage frame 14; as the integrated rod 8 continues to descend, the first elastic member 7 changes from the original extended state (needing to bear the gravity of the clamping column 5) to the compressed state, and the copper busbar can be pressed against the support block 2 through this compressed state.
[0055] After that, the integrated rod 8 continues to descend, and the driving cylinder 13 acts on the top of the linkage frame 14 and presses the linkage frame 14 downward, while compressing the second elastic member 16 and the first elastic member 7. At this time, although the linkage frame 14 lowers the height of the lifting block 3, the support area of the bottom of the copper busbar is reduced, but because the pressure of the first elastic member 7 gradually increases at this time, the copper busbar can be fully pressed by the stabilizing plate 6 and the support block 2.
[0056] Finally, the height of the integrated rod 8 reaches the lowest point. At this time, the position of the copper bar is fully fixed, and the lifting block 3 and the end block 4 are both lower than the copper bar. At the same time, the width of the support block 2 is small, and the diameter of the stabilizing plate 6 is also smaller than the width of the copper bar. In this way, the copper bar is clamped and fixed in the middle by the stabilizing plate 6 and the support block 2, and the edges are all in an open state, which can be easily polished. Although the linkage frame 14 and the driving frame 9 are located on the side of the copper bar, the middle of the linkage frame 14 and the driving frame 9 are a certain distance away from the copper bar and do not affect the workers' operation. In this way, the workers can directly bypass the driving frame 9 and the linkage frame 14 to polish the edges of the copper bar, thereby ensuring that the entire polishing process can proceed normally and smoothly.
[0057] After polishing is completed, the cylinder 10 only needs to be driven to raise the height of the integrated rod 8. At this time, the support block 2 is raised by the second elastic member 16 to support the copper bar. The end block 4 can easily limit the copper bar, making it easier to remove the copper bar stably. Secondly, the stabilizing plate 6 is separated from the copper bar after the support block 2 is raised to the highest position. In this way, the stabilizing plate 6 can also ensure that the copper bar does not shift in position and prevent the end block 4 from lifting the copper bar. Throughout the entire process, only one driving cylinder 10 is needed to achieve the compression and release of the copper bar, reducing costs.
[0058] The stabilizing plate 6 has a larger diameter, which can improve the pressing stability of the copper bar. Secondly, the side wall of the stabilizing rod 12 is limited by the stabilizing arm 11, thereby improving the position stability of the integrated rod 8. At the same time, when polishing copper bars of different widths, it is also necessary to adjust the position of the adjusting plate 19 so that the stabilizing plate 6 and the support block 2 act on the middle or near the middle of the copper bar (actual positioning and support do not require very precise positioning). When adjusting the position of the end block 4, it is only necessary to remove the adjusting bolt 21, move the adjusting plate 19 to the appropriate position, and then pass the adjusting bolt 21 through the pre-opening on the adjusting plate 19 and thread it into the adjusting hole 20. It is simple and convenient.
[0059] The above description is only a description of the preferred embodiment of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
