[0001] This utility model relates to the field of meter housing processing technology, and in particular to a punching device for meter housing. Background Technology

[0002] Perforation in an electricity meter casing refers to the holes created during the manufacturing process of the meter casing through a stamping process to meet the needs of internal component installation, wiring, and heat dissipation. These holes may be used for wire passage, screw installation, ventilation, heat dissipation, or other functional purposes.

[0003] Patent application publication number CN221966550U discloses a punching device, including a base, a support plate fixedly connected to the top of the base, and a second threaded rod rotatably connected to one side of the support plate. While this patent achieves collection and cleaning functions by incorporating a collection box, filter plate, magnet, and collection trough—where metal debris generated during punching enters the collection box under the magnetic force of the magnet in the collection trough, allowing the collection box to be pulled out of the base for debris cleaning—the lack of a positioning mechanism during the punching process affects positioning accuracy and fails to provide additional stability at the punching head, potentially leading to deviations in the punching position.

[0004] In view of the existing patents, there is a need to provide a punching device for meter housing with positioning function. Utility Model Content

[0005] In order to overcome the shortcomings of current patents that do not have a positioning mechanism during the punching process, which affects the positioning accuracy and cannot provide additional stability when punching the head, and may eventually lead to deviation in the punching position, this utility model provides a punching device for electric meter housing with positioning function.

[0006] The technical solution of this utility model is as follows: a punching device for an electric meter housing, comprising a mounting base plate, a movable frame, a placement frame, a punching assembly, and a clamping mechanism. The movable frame is slidably arranged on the mounting base plate, and the placement frame is fixedly connected to the top of the mounting base plate. The punching assembly is mounted on the movable frame, and the clamping mechanism is arranged on the placement frame. The clamping mechanism is used to clamp and fix the electric meter housing. It also includes a mounting frame, positioning rods, connecting blocks, and a first elastic element. The mounting frame is fixedly connected to the bottom of the movable frame, and connecting blocks are fixedly connected to both the front and rear sides of the mounting frame. Two positioning rods are slidably arranged on the connecting blocks, and the positioning rods are connected to the connecting blocks by a first elastic element.

[0007] In one embodiment, the clamping mechanism includes a guide frame, a clamping frame, and a second elastic member. Guide frames are slidably arranged on both the left and right sides of the placement frame, and clamping frames are slidably arranged on the guide frames. Two second elastic members are sleeved on the clamping frames, and the two ends of the second elastic members are respectively connected to the guide frames and the clamping frames.

[0008] In one embodiment, an air jet pipe is also included, with the air jet pipe disposed on the mounting bracket.

[0009] In one embodiment, a rubber sheet is also included, with the rubber sheet bonded to the contact surface between the clamping frame and the meter housing.

[0010] In one embodiment, a plastic sheet is also included, with the plastic sheet bonded to the contact surface between the guide frame and the meter housing.

[0011] In one embodiment, two handles are fixedly connected to one side of the guide frame.

[0012] Compared with the prior art, the present invention provides a punching device for an electric meter housing, which has the following advantages: 1. The moving frame is pushed to slide along the mounting base plate, so that the punching component is close to the target punching point. The positioning rod automatically fits the surface of the electric meter housing during the movement and floats slightly through the first elastic element to adapt to the unevenness of the housing surface, ensure positioning accuracy, and provide additional stability when the punching component is operating.

[0013] 2. During or after punching, the air pump generates airflow that is ejected through the jet pipe to blow away the metal debris generated during punching, thereby keeping the work area clean and preventing debris from affecting subsequent operations or causing safety hazards.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: A punching device for an electricity meter housing, please refer to... Figures 1-3 The device includes a mounting base plate 1, a movable frame 2, a placement frame 3, a punching assembly 4, and a clamping mechanism. The movable frame 2 is slidably mounted on the mounting base plate 1, and the placement frame 3 is fixedly connected to the top of the mounting base plate 1. The punching assembly 4 is mounted on the movable frame 2, and the clamping mechanism is provided on the placement frame 3. The clamping mechanism is used to clamp and fix the meter housing. The clamping mechanism includes a guide frame 10, a clamping frame 11, and a second elastic element 12. Guide frames 10 are slidably mounted on both the left and right sides of the placement frame 3. The clamping frame 11 is slidably mounted on the guide frame 10, and two second elastic elements 12 are sleeved on the clamping frame 11. The two ends of the second elastic elements 12 are respectively connected to the guide frame 10 and the clamping frame. The 11 connection also includes a mounting bracket 5, a positioning rod 6, a connecting block 7, and a first elastic element 8. The mounting bracket 5 is fixedly connected to the bottom of the movable frame 2. The connecting blocks 7 are fixedly connected to both the front and rear sides of the mounting bracket 5. Two positioning rods 6 are slidably arranged on the connecting blocks 7. The first elastic element 8 is connected between the positioning rods 6 and the connecting blocks 7. A rubber plate 13 is bonded to the contact surface between the clamping frame 11 and the meter housing to protect the surface of the meter housing from damage. A plastic plate 14 is bonded to the contact surface between the guide frame 10 and the meter housing to increase friction and prevent the meter housing from moving. The handle is used to increase the point of force between the hand and the guide frame 10, making it easier to push the guide frame 10.

[0019] When this device is needed, first manually pull the clamping frame 11 outward to stretch the second elastic element 12. Then place the meter housing to be punched on the guide frame 10, ensuring that its edge is aligned with the guide reference. After placement, release the clamping frame 11, and the second elastic element 12 returns to its original state, pushing the clamping frame 11 inward to firmly clamp the meter housing. Next, push the moving frame 2 to slide along the mounting base plate 1, bringing the punching assembly 4 closer to the target punching point. The positioning rod 6 automatically fits against the surface of the meter housing during movement and floats slightly through the first elastic element 8 to adapt to unevenness of the housing surface, ensuring positioning accuracy and providing additional stability when the punching assembly 4 is operating. Subsequently, start the punching assembly 4 to punch the meter housing. If punching is required at different locations on the meter housing, the position of the guide frame 10 can be finely adjusted to adapt to different meter housing sizes, so as to accurately position the punching point.

[0020] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 2 It also includes a jet pipe 9, which is installed on the mounting bracket 5.

[0021] Before using this device, the external air pump should be connected to the jet pipe 9. During or after the punching process, the airflow generated by the air pump is ejected through the jet pipe 9 to blow away the metal debris generated during the punching process, thereby keeping the work area clean and preventing debris from affecting subsequent operations or causing safety hazards.
