Description

Technical Field

[0001] This invention relates to the field of electricity metering box manufacturing technology, specifically to a manufacturing and processing device for electricity metering boxes. Background Technology

[0002] Electricity metering boxes are critical infrastructure components in power systems, used for the installation and protection of metering equipment such as electricity meters, transformers, and data acquisition terminals. Their enclosures are typically made of metal plates or engineering plastics, and their panels require the machining of numerous high-precision, multi-specification functional holes, such as mounting screw holes for fixing the electricity meter, inlet and outlet holes for wires, ventilation holes, and lead-sealed holes. The dimensional accuracy, relative positional accuracy, and machining efficiency of these holes directly determine the assembly quality, sealing performance, and operational reliability of the metering box.

[0003] However, with existing drilling equipment, when production tasks are switched to different specifications of electricity metering boxes, it is usually necessary to stop the machine and perform cumbersome mold changes and repositioning adjustments. This mode cannot meet the production needs of small batches and multiple varieties of electricity metering boxes, resulting in low equipment utilization. On the other hand, due to the need for internal cables to connect to the equipment, multiple openings are usually set on the side of the electricity metering box. In actual production, in order to perform drilling operations on different sides of the electricity metering box, it is usually necessary to repeatedly re-clamp and fix the electricity metering box on the drilling equipment, which is inefficient and may lead to a decrease in the accuracy of the drilling position.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-9 The present invention provides a technical solution: a production and processing device for an electricity metering box, including a processing table 1, a fixing structure 2 in the middle of the processing table 1, a positioning structure 4 connected between the fixing structure 2 and the processing table 1, a drilling structure 3 on the top side of the processing table 1, and a fastening structure 5 connected between the fixing structure 2 and the positioning structure 4. The fixed structure 2 includes a first positioning frame 202 and a second positioning frame 203. Two first positioning frames 202 and two second positioning frames 203 are arranged parallel to each other in the middle of the processing table 1. The ends of the first positioning frames 202 and the second positioning frames 203 are slidably connected to the inner side of the processing table 1. The two first positioning frames 202 and the two second positioning frames 203 are arranged in a "well" shape. Two first support rods 204 and two second support rods 205 are arranged in a rectangular shape in the middle of the processing table 1. The first support rods 204 and the second support rods 205 are slidably connected to the intersections of adjacent first positioning frames 202 and second positioning frames 203, respectively. The middle of the processing table 1 is fixed. A mounting bracket 206 is connected, and the mounting bracket 206 has an "X" shaped structure. The bottom end of the second support rod 205 is rotatably connected to a pulley 209. The bottom end of the second support rod 205 is slidably connected to the mounting bracket 206 through the pulley 209. The top ends of the first support rod 204 and the second support rod 205 are both square structures. The bottom end of the first support rod 204 is rotatably connected to a threaded block 208. The middle part of the mounting bracket 206 is rotatably connected to a central shaft block 207. The middle part of the central shaft block 207 is rotatably connected to an adjusting screw 201. The two sides of the adjusting screw 201 have opposite thread directions. The two threaded blocks 208 are respectively threaded to the two ends of the adjusting screw 201.

[0022] In practical use, the positions of the first support rod 204 and the second support rod 205 are adjusted according to the specifications of the box. The user can rotate the adjusting screw 201 located on the side of the processing table 1 around the central axis block 207. The first support rod 204 is rotatably connected to the two threaded blocks 208 threaded at both ends of the adjusting screw 201, while the two second support rods 205 are slidably connected to the mounting bracket 206 through the pulleys 209 on the bottom side. Combined with the restraining effect of the mounting bracket 206, when the adjusting screw 201 is rotated, the first support rod 204 and the second support rod 205 will slide between themselves and the corresponding first positioning bracket 202 and second positioning bracket 203, respectively. At the same time, the side length of the rectangle formed by the ends of the two first support rods 204 and the two second support rods 205 will also change. In addition, depending on the size of the box to be processed, the user can also rotate... Adjusting screw 201 causes the two threaded blocks 208 to slide in opposite directions, which in turn drives the first positioning frame 202 and the second positioning frame 203 to slide through the two first support rods 204. Finally, while maintaining the support shape, the size of the support surface is adjusted, and the electricity metering box to be processed is placed in the middle of the processing table 1. After adjusting so that the two first support rods 204 and the two second support rods 205 respectively abut against the four corners of the inner side of the box, the support and fixation of the box can be completed, ensuring the stability of the box during drilling the side of the box. When repeating the operation on the same specification box, the user can tighten or expand the four support rods by rotating the adjusting screw 201 while maintaining the deflection angle of the adjusting screw 201, ensuring the support effect of the box and facilitating the removal and placement of the processed box.

[0023] The positioning structure 4 includes an arc-shaped slider 401. An arc-shaped slider 401 is slidably connected to each side of the processing table 1. The end of the adjusting screw 201 is rotatably connected to the arc-shaped slider 401 on the same side. An arc-shaped rack 405 is fixedly connected to the inner side of the processing table 1. A toothed slider 402 is slidably connected to the inner side of the arc-shaped slider 401. The toothed slider 402 meshes with the arc-shaped rack 405. A first spring 404 is fixedly connected between the toothed slider 402 and the arc-shaped slider 401. An abutment groove 403 is provided on the bottom side of the toothed slider 402. A release rod 406 is slidably connected to the middle of the arc-shaped slider 401. A second spring 407 is fixedly connected between the end of the release rod 406 and the arc-shaped slider 401. A protrusion structure is provided on the side of the release rod 406. The release rod 406 abuts against the toothed slider 402 through the protrusion on the side.

[0024] In practical use, in order to position and lock the adjusting screw 201 when adjusting its deflection angle, an arc rack 405 is provided on the inner side of the processing table 1. When the adjusting screw 201 rotates around the central shaft block 207, the toothed slider 402 on the inner side of the arc-shaped slider 401 at the end of the adjusting screw 201 will mesh with the arc rack 405, thereby facilitating the positioning of the deflection angle of the adjusting screw 201. A release rod 406 is provided on the bottom side of the toothed slider 402. When the user presses the release rod 406, the protrusion on the side of the release rod 406 will engage with the abutment groove on the bottom side of the toothed slider 402. When 403 is aligned, the toothed slider 402 can slide inward toward the arc-shaped slider 401, thereby achieving the positioning effect on the rotation angle of the adjusting screw 201. After the adjustment of the rotation angle of the adjusting screw 201 is completed, the user can release the release rod 406. At this time, the protruding structure on the side of the release rod 406 is offset from the contact groove 403, and the side of the release rod 406 directly abuts against the toothed slider 402 through the protruding structure. At this time, the toothed slider 402 cannot slide, thereby locking the current deflection angle of the adjusting screw 201 and ensuring the fixed support position of the four support rods.

[0025] The drilling structure 3 includes a guide rail 301. The top side of the processing table 1 is fixedly connected to the guide rail 301, which has a ring structure. A mounting plate 302 is slidably connected to the guide rail 301. A dual-axis drilling device is mounted on the mounting plate 302. Multiple positioning grooves 304 are opened on the side of the guide rail 301, and the arc between adjacent positioning grooves 304 is 90°. A positioning lever 306 is rotatably connected to the bottom side of the mounting plate 302. A torsion spring 307 is fixedly connected between the positioning lever 306 and the mounting plate 302. The side of the positioning lever 306 is engaged with the guide rail 301 through the positioning groove 304. A support frame 303 is slidably connected to the middle of the processing table 1. The top and bottom sides of the support frame 303 are both "X" shaped. A hydraulic rod 305 is mounted on the bottom side of the mounting frame 206. The bottom side of the support frame 303 is fixedly connected to the hydraulic rod 305.

[0026] In practical use, after the box is fixed by the first support rod 204 and the second support rod 205, a mounting plate 302 is provided on the side of the processing table 1, which slides along the annular guide rail 301. A dual-axis drilling device for drilling holes in the box is mounted on the mounting plate 302. By rotating the mounting plate 302 along the guide rail 301, the drilling device can be positioned on different sides of the box for drilling operations. During this process, the electricity metering box remains in a fixed state, eliminating the need for repeated clamping and fixing of the box, thus improving processing efficiency and accuracy. On the other hand, a positioning groove 304 is provided on the guide rail 301. When the mounting plate 302 moves to the positioning groove 304, the mounting plate 302... The positioning lever 306 on the bottom side engages with the positioning groove 304 under the action of the torsion spring 307, thereby fixing the current position of the mounting plate 302. This ensures that the drilling equipment and the current side of the box are aligned, guaranteeing drilling accuracy and preventing the mounting plate 302 from shifting during drilling. On the other hand, a support frame 303 driven by a hydraulic rod 305 is also provided in the middle of the processing table 1. The top and bottom sides of the support frame 303 are both cross-shaped, which can support the bottom opening side of the box. At the same time, the height of the support frame 303 can be adjusted by the hydraulic rod 305 according to the specifications of the box, thereby achieving longitudinal adjustment of the drilling position and improving operational flexibility.

[0027] The fastening structure 5 includes an inclined abutment block 501. The inclined abutment block 501 is slidably connected to the inner side of the arc-shaped slider 401. A third spring 502 is fixedly connected between the inclined abutment block 501 and the arc-shaped slider 401. An elastic brake block 503 is fixedly connected to the side of the inclined abutment block 501. The elastic brake block 503 abuts against the side of the adjusting screw 201. A limiting groove 505 is opened on the inner side of the arc-shaped slider 401. A threaded push block 504 is slidably connected to the arc-shaped slider 401 through the limiting groove 505. The side of the threaded push block 504 is slidably connected to the inclined side of the inclined abutment block 501. A fastening screw 506 is threadedly connected to the middle of the threaded push block 504. The end of the fastening screw 506 is rotatably connected to the arc-shaped slider 401.

[0028] In practical use, vibrations are generated during the drilling process of the box. To prevent the adjusting screw 201 from rotating due to vibration, which would affect the support effect of the first support rod 204 and the second support rod 205 on the box, after adjusting the position of the adjusting screw 201, the user can rotate the fastening screw 506 located on one side of the arc-shaped slider 401. When the fastening screw 506 rotates, it will drive the threaded push block 504 to slide in the limiting groove 505. At the same time, the threaded push block 504 will push the inclined abutment block 501 on the side to the side, so that the elastic braking block 503 at the end of the inclined abutment block 501 is in close contact with the side of the adjusting screw 201, preventing the adjusting screw 201 from rotating and ensuring stable support for the electricity metering box.

[0029] Working Principle: First, two first positioning frames 202 and second positioning frames 203 arranged in a "well" shape are located in the middle of the processing table 1. First support rods 204 and second support rods 205 slide at the intersection of the first positioning frames 202 and second positioning frames 203, respectively. When drilling holes in the electricity metering box, the positions of the first support rods 204 and second support rods 205 need to be adjusted according to the box specifications. The user can rotate the adjusting screw 201 located on the side of the processing table 1 around the central axis block 207. The first support rods 204 are rotatably connected to two threaded blocks 208 threaded at both ends of the adjusting screw 201, while the two second support rods 205 are slidably connected to the mounting frame 206 via pulleys 209 on the bottom side. Combined with the restraining effect of the mounting frame 206, when the adjusting screw 201 rotates, the first support rods 204 and second support rods 205 will slide against the corresponding first positioning frames 202 and second positioning frames 203, respectively. Simultaneously, the two first support rods 204 and 205 slide against the corresponding first positioning frames 202 and second positioning frames 203. The side length of the rectangle formed by the ends of the 4 and the two second support rods 205 will also change. At the same time, depending on the size of the box to be processed, the user can also rotate the adjusting screw 201 to make the two threaded blocks 208 slide in opposite directions, thereby driving the first positioning frame 202 and the second positioning frame 203 to slide through the two first support rods 204. Finally, while keeping the support shape unchanged, the size of the support surface is adjusted, and the electricity metering box to be processed is placed in the middle of the processing table 1. After the two first support rods 204 and the two second support rods 205 respectively abut against the four corners of the inner side of the box, the support and fixation of the box can be completed, ensuring the stability of the box during the drilling of the side of the box. When repeating the operation on the same specification box, the user can tighten or expand the four support rods by rotating the adjusting screw 201 while maintaining the deflection angle of the adjusting screw 201, ensuring the support effect of the box and facilitating the removal and placement of the processed box.

[0030] To position and lock the adjusting screw 201 during adjustment of its deflection angle, an arc-shaped rack 405 is provided on the inner side of the machining table 1. When the adjusting screw 201 rotates around the central shaft block 207, the toothed slider 402 on the inner side of the arc-shaped slider 401 at the end of the adjusting screw 201 engages with the arc-shaped rack 405, thus facilitating the positioning of the adjusting screw 201's deflection angle. A release lever 406 is provided on the bottom side of the toothed slider 402. When the user presses the release lever 406, the protrusion on the side of the release lever 406 engages with the abutment groove 403 on the bottom side of the toothed slider 402. When aligned, the toothed slider 402 can slide inward to the inside of the arc-shaped slider 401, thereby achieving the positioning effect on the rotation angle of the adjusting screw 201. After the adjustment of the rotation angle of the adjusting screw 201 is completed, the user can release the release rod 406. At this time, the protruding structure on the side of the release rod 406 is offset from the contact groove 403, and the side of the release rod 406 directly contacts the toothed slider 402 through the protruding structure. At this time, the toothed slider 402 cannot slide, thereby locking the current deflection angle of the adjusting screw 201 and ensuring the fixed support position of the four support rods.

[0031] After the box is fixed by the first support rod 204 and the second support rod 205, a mounting plate 302 is provided on the side of the processing table 1, which slides along the annular guide rail 301. A dual-axis drilling device for drilling holes in the box is mounted on the mounting plate 302. By rotating the mounting plate 302 along the guide rail 301, the drilling device can be positioned on different sides of the box for drilling operations. During this process, the electricity metering box remains in a fixed state, eliminating the need for repeated clamping and fixing of the box, thus improving processing efficiency and accuracy. On the other hand, a positioning groove 304 is provided on the guide rail 301. When the mounting plate 302 moves to the positioning groove 304, the bottom side of the mounting plate 302... Under the action of the torsion spring 307, the side of the positioning lever 306 engages with the positioning groove 304, thereby fixing the current position of the mounting plate 302. This ensures that the drilling equipment and the current side of the housing are aligned, guaranteeing drilling accuracy and preventing the mounting plate 302 from shifting during drilling. On the other hand, a support frame 303 driven by a hydraulic rod 305 is also provided in the middle of the processing table 1. The top and bottom sides of the support frame 303 are both cross-shaped, which can support the bottom opening side of the housing. At the same time, the height of the support frame 303 can be adjusted by the hydraulic rod 305 according to the specifications of the housing, thereby achieving longitudinal adjustment of the drilling position and improving operational flexibility.

[0032] Because vibrations are generated during the drilling process of the box, in order to prevent the adjusting screw 201 from rotating due to vibrations, which would affect the supporting effect of the first support rod 204 and the second support rod 205 on the box, after the position of the adjusting screw 201 is adjusted, the user can rotate the fastening screw 506 located on one side of the arc-shaped slider 401. When the fastening screw 506 rotates, it will drive the threaded push block 504 to slide in the limiting groove 505. At the same time, the threaded push block 504 will push the inclined abutment block 501 on the side to the side, so that the elastic braking block 503 at the end of the inclined abutment block 501 will be in close contact with the side of the adjusting screw 201, preventing the adjusting screw 201 from rotating and ensuring stable support for the electricity metering box.
