Description

Technical Field

[0001] This utility model relates to the field of electricity metering box manufacturing technology, specifically to a quick-pressing clamp for the hinge of an electricity metering box door panel. Background Technology

[0002] Electricity metering boxes are critical equipment in electricity distribution. Their doors are connected to the box body via hinges and require frequent opening and closing. To prevent dust and water damage, enhance structural strength, and facilitate installation and sealing, electricity metering box doors typically feature a flanged design. Furthermore, to ensure reliability and lifespan, the door hinges need to be fixed to the door panel with extremely high connection strength and positional accuracy. Press-fitting is the mainstream method for installing electricity metering box hinges due to its strong connection and high efficiency. This method uses clamps to achieve precise positioning and reliable clamping of the door panel as needed.

[0003] However, in existing technologies, such clamps often use pressure applied to the outer surface of the door panel for clamping, such as pressing the edge of the door panel from the side with a pressure plate. However, the door panels of electricity metering boxes are mostly thin plate components with limited rigidity. If the clamping force applied by this external clamping method is not properly controlled, it can easily lead to irreversible indentations or even overall warping deformation of the door panel, affecting the product's appearance and sealing performance. Utility Model Content

[0004] The purpose of this invention is to provide a quick-pressing clamp for the hinge of the door panel of an electricity metering box, so as to solve the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-pressing and riveting fixture for a door panel hinge of an electricity metering box, comprising a processing table, a support frame fixedly mounted on the processing table, and a fixed frame mounted on the support frame; a bidirectional screw is rotatably mounted on the fixed frame, and movable blocks are threadedly connected to both sides of the bidirectional screw; two rotating rods are rotatably mounted at the bottom of each movable block, and an external support rod is fixedly mounted at the bottom of each rotating rod; when the bidirectional screw rotates, it drives each external support rod to abut against the inner wall of the door panel, thereby completing alignment and clamping while pressing the door panel.

[0006] Preferably, each of the external support rods has a rotating wheel rotatably mounted at the end furthest from the rotating rod.

[0007] Preferably, limit rods are fixedly provided on both sides of the fixed frame, and each of the moving blocks is slidably connected to each of the limit rods.

[0008] Preferably, each of the movable blocks is fixedly provided with a fixing plate at its bottom, and each fixing plate is fixedly provided with a spring on both sides. The end of each spring away from the fixing plate is fixedly connected to each of the external support rods.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Please see Figure 1-4 A quick-pressing clamp for the hinge of an electricity metering box door panel is disclosed. The proposed technical solution includes a processing table 1, a support frame 2 fixedly mounted on the processing table 1, and a fixed frame 4 mounted on the support frame 2. A bidirectional screw 8 is rotatably mounted on the fixed frame 4. Moving blocks 10 are threadedly connected to both sides of the bidirectional screw 8. Two rotating rods 11 are rotatably mounted at the bottom of each moving block 10, and an outer support rod 12 is fixedly mounted at the bottom of each rotating rod 11. When the bidirectional screw 8 rotates, it drives each outer support rod 12 to abut against the inner wall of the door panel 16, thus completing alignment and clamping while pressing the door panel 16. The fixed frame 4 slides up and down on the support frame 2. The moving blocks 10 are threadedly connected to the bidirectional screw 8, and the bottom of the outer support rod 12 is flush with the bottom of the fixed frame 4. Since most electricity metering box door panels have a flanged design, initially, the top of the fixed frame 4 abuts against the inner top wall of the support frame 2, and there is a certain angle between each outer support rod 12 and the bidirectional screw 8. In use, the door panel 16 is placed on the processing table 1 with the side requiring the hinge to be riveted facing the upper fixing frame 4, i.e., the flanged side facing upwards. At this time, the fixing frame 4 moves downwards. When the bottom of the fixing frame 4 abuts against the door panel 16, the bottom surfaces of each outer support rod 12 also abut against the door panel 16. The fixing frame 4 and the outer support rods 12 can press the door panel 16 tightly onto the processing table 1. Then, the bidirectional screw 8 is driven to rotate. When the bidirectional screw 8 rotates, it drives the moving block 10 to move to both sides, thereby causing each outer support rod 12 to move towards the inner wall of the flanged side at both ends of the door panel 16. During the movement, the door panel 16 is moved by the outer support rods 12, which enables the door panel 16 to be aligned in the axial direction of the bidirectional screw 8. When the ends of each external support rod 12 are in contact with both ends of the door panel 16, the bidirectional screw 8 is rotated further. At this time, the moving block 10 continues to move to both sides, and each external support rod 12, while in contact with the door panel 16, will open outwards, thereby abutting against the other two sides of the door panel 16, thus aligning the door panel 16 in the radial direction of the bidirectional screw 8. At this time, the ends of each external support rod 12 abut against the four corners of the door panel 16, thereby completing the alignment and fixation of the door panel through external support, and also pressing the door panel firmly onto the worktable 1.

[0021] Specifically, each outer support rod 12 has a rotating wheel 13 rotatably mounted at the end away from the rotating rod 11; when the end of the outer support rod 12 abuts against the side wall of the door panel 16, the rotating wheel 13 can reduce friction, so that the end of the outer support rod 12 can smoothly abut against the four corners of the door panel 16, allowing the door panel to quickly complete the alignment.

[0022] Specifically, limit rods 9 are fixedly installed on both sides of the fixed frame 4, and each moving block 10 is slidably connected to each limit rod 9 in a one-to-one correspondence; the limit rods 9 limit the corresponding moving block 10, thereby preventing the moving block 10 from rotating when the bidirectional screw 8 rotates.

[0023] Specifically, each movable block 10 has a fixed plate 14 at its bottom, and each fixed plate 14 has a spring 15 fixed on both sides. The end of each spring 15 away from the fixed plate 14 is fixedly connected to each external support rod 12. By setting the spring 15 between the external support rod 12 and the fixed plate 14, a certain angle is created between the external support rod 12 and the double-acting screw 8. After the door panel 16 completes the hinge riveting, the double-acting screw 8 is reversed. At this time, the movable block 10 is reset, and the spring 15 causes each external support rod 12 to retract, thereby reducing the space occupied by the external support rod 12 and making it easier for the external support rod 12 to fall between the four flanges of the door panel 16 next time. When the bottom of the external support rod 12 abuts against the door panel 16, the height of the double-acting screw 8 is higher than that of the door panel 16.

[0024] Specifically, a hydraulic cylinder 3 is fixedly installed on the top of the support frame 2, and the piston rod end of the hydraulic cylinder 3 is fixedly connected to the fixed frame 4. The fixed frame 4 is moved up and down by the hydraulic cylinder 3, so that the bottom of the fixed frame 4 and the bottom of the outer support rod 12 can press the door panel 16 tightly, and the clamping is completed by the outward expansion of the outer support rod 12.

[0025] Specifically, a servo motor 5 is fixedly installed inside the mounting bracket 4, and a drive gear 6 is fixedly installed at the output end of the servo motor 5. A driven gear 7 that meshes with the drive gear 6 is installed inside the mounting bracket 4, and the driven gear 7 is fixedly connected to the bidirectional screw 8. Both the drive gear 6 and the driven gear 7 are rotatably mounted inside the mounting bracket 4. When the bottom wall of the mounting bracket 4 abuts against the door panel 16, each of the outer support rods 12 retracts to both sides of the bidirectional screw 8, thereby ensuring that each of the outer support rods 12 is on the door panel 16. At this time, the servo motor 5 drives the drive gear 6 to rotate, which in turn drives the bidirectional screw 8 to rotate in both directions through the driven gear 7, thereby controlling the clamping and releasing of the outer support rods 12 on the door panel 16.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
