Description

Technical Field

[0001] This utility model relates to the field of drilling technology for the back panel of a power distribution box, and specifically to a drilling device for the back panel of a power distribution box. Background Technology

[0002] In the field of power equipment and industrial control, distribution boxes, as the basic load-bearing units of electrical systems, directly affect the stability and safety of equipment operation through their structural design and manufacturing process. Currently, the back panel of distribution boxes generally employs traditional mechanical drilling technology, machining through holes in metal sheets to achieve functions such as electrical connection, heat dissipation and ventilation, and mechanical fixation.

[0003] However, in existing technologies, when drilling holes in different positions on the back plate, it is usually necessary to adjust the back plate back and forth to ensure that the area to be drilled is directly below the drilling head. This requires back-and-forth movement, which results in the clamping and adjustment time accounting for more than 1 / 3 of the total working time when machining multiple holes. This not only significantly increases the labor intensity, but also introduces errors due to repeated positioning, making it difficult to consistently achieve the industry standard of CPK≥1.33 for hole machining accuracy.

[0004] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0015] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0016] like Figures 1 to 3 As shown, this utility model relates to a punching device for the back panel of a power distribution box, including: a processing table 1, an adjusting component 2 for adjusting the angle of the punching head 30°, and a fixing component 3 for fixing the back panel; The processing table 1 is provided with a placement rack 4, and a placement net 41 is elastically installed on the placement rack 4. The lower end of the placement net 41 is provided with a collection groove 42. The fixing component 3 includes: a fixing frame 31 fixedly installed on the processing table 1, a clamping plate 32 slidably installed on the fixing frame 31, teeth 33 formed on the clamping plate 32, a gear 34 rotatably installed on the fixing frame 31, a clamping plate 35 meshing with the other end of the gear 34, and a cylinder 36 for pushing the clamping plate 32 to move; the clamping plate 32 meshes with the gear 34.

[0017] When drilling is required on the back panel of the distribution box, the worker places the back panel to be drilled steadily on the placement net 41. At this time, the drive cylinder 36 is activated, pushing clamping plate 32 to move precisely towards the back panel. During the movement of clamping plate 32, drive gear 34 starts to rotate synchronously. As gear 34 rotates, clamping plate 35, which meshes with gear 34, moves in the opposite direction to clamping plate 32, thereby achieving automatic clamping and stable fixation of the back panel.

[0018] It is important to note that when using mechanical drilling, metal debris is easily embedded inside the formed holes. Simultaneously, metal debris will also remain on the placement mesh 41. If these residual metal debris are not cleaned promptly, they are highly likely to scratch the back panel surface during the next loading, affecting product quality.

[0019] The clamping plate 32 has multiple protrusions 321, and the placement net 41 has multiple abutment blocks 322. Therefore, when the cylinder 36 drives the clamping plate 32 to perform a separation action, the protrusions 321 on the clamping plate 32 will interact with the abutment blocks 322. Under the reaction force of the abutment blocks 322, the clamping plate 32 will reciprocate up and down along the vertical direction of the placement frame 4. It should be noted that an elastic reset element—a spring—is configured between the placement frame 4 and the placement net 41. Under the synergistic action of the protrusions 321 and the abutment blocks 322, the spring can drive the placement net 41 to achieve automatic reset.

[0020] Through the aforementioned mechanical linkage design, the following effect can be achieved after the drilling operation: when the cylinder 36 pushes the clamping plate assembly to release the back plate, the vibration mechanism of the placement mesh 41 is triggered simultaneously. This vibration can effectively remove metal shavings attached to the surface of the back plate and the placement mesh 41, ensuring the cleanliness requirements of subsequent processing.

[0021] The adjustment assembly 2 includes: a lifting frame 21 fixedly installed on the processing table 1, a mounting plate 23 slidably installed on the lifting frame 21, a threaded rod 24 fixedly installed on the lifting frame 21, a motor 25 driving the threaded rod 24 to rotate, an arm plate 26 rotatably installed on the mounting plate 23, a motor 27 driving the arm plate 26 to rotate, a wall plate 28 rotatably installed on the arm plate 26, a motor 29 driving the arm plate 2 to rotate along the wall plate 1, and a punching head 30 fixedly installed on the arm plate 2; the mounting plate 23 has a threaded hole; the threaded hole is threadedly connected to the threaded rod 24.

[0022] Once the back plate is clamped, the threaded rod 24 is driven to rotate by motor 25, which in turn moves the mounting plate 23 vertically, thereby adjusting the height of the punch head 30. Then, the arm plate 26 is driven to rotate along the rotation point of the mounting plate 23 by motor 27. The series arrangement of multiple arm plates forms a spatial linkage mechanism, which significantly expands the working space and attitude adjustment range of the device.

[0023] Through a parameterized adjustment mechanism in three-dimensional space, the drilling device can quickly respond to complex processing requirements without the need for secondary clamping and adjustment of the already positioned back plate, effectively shortening auxiliary processing time and significantly improving overall operating efficiency and processing accuracy.

[0024] Working Principle: When drilling is required on the back panel of the distribution box, the operator places the back panel to be drilled on the placement net 41. At this time, the drive cylinder 36 pushes the clamping plate 32 towards the back panel. When the clamping plate 32 moves towards the back panel, the drive gear 34 rotates. As the gear 34 rotates, the clamping plate 35, which meshes with the gear 34, moves in the opposite direction to the clamping plate 32, thereby achieving automatic clamping and fixing of the back panel. After the back panel is clamped, the motor 25 drives the threaded rod 24 to rotate, thereby driving the mounting plate 23 to move vertically, thus adjusting the height of the drilling head 30. Then, the drive motor 27 drives the arm plate 26 to rotate along the rotation point of the mounting plate 23. The series arrangement of multiple arm plates forms a spatial linkage mechanism, which significantly expands the working space and attitude adjustment range of the device. Through a parameterized adjustment mechanism in three-dimensional space, the drilling device can quickly respond to complex processing requirements without the need for secondary clamping and adjustment of the already positioned back plate, effectively shortening auxiliary processing time and significantly improving overall operating efficiency and processing accuracy.
