Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet processing technology, and in particular to a drilling fixture for power distribution cabinet accessories. Background Technology

[0002] Distribution cabinets are key equipment used for power distribution, control and protection in power systems. They are widely used in industrial, commercial, building and infrastructure fields. Distribution cabinets consist of cabinet body, door panel, side panel and some internal frame. When fixing the cabinet body, installing incoming and outgoing lines on the side panel and customizing accessories such as indicator lights on the door panel, drilling is required for the corresponding accessories of the distribution cabinet.

[0003] In new construction projects, expansion or renovation projects, and public facility construction, a large number of distribution cabinets are needed to ensure a stable and secure power supply to different areas or equipment in order to meet the power distribution needs of the entire project. These distribution cabinets require monitoring the status of numerous circuits or devices. When customizing and installing a large number of indicator lights and other accessories on the cabinet doors, batch drilling on-site is usually required. Currently, this is generally done manually, with manual positioning followed by manual drilling using a handheld drill. However, manual positioning typically involves using rulers, pens, and other tools to mark specific points on the cabinet doors to be processed. There are several issues with on-site drilling. First, inaccurate positioning and hole misalignment affect the accuracy of drilling positions and require significant time for positioning, impacting drilling efficiency. Second, directly hand-held drilling lacks support around the hole, making it difficult to control drilling force manually. Excessive pressure can deform the door panel, resulting in poor drilling quality. Third, the reason for manual on-site drilling in such situations is the inconvenience of transporting and assembling precision drilling equipment. Precision drilling equipment is complex and costly to assemble on-site, and there is currently no universal drilling fixture for portable on-site drilling of electrical cabinet components.

[0004] Therefore, in order to improve the accuracy of drilling positioning and increase drilling efficiency, this invention provides a drilling fixture for power distribution cabinet accessories. Summary of the Invention

[0012] In the aforementioned drilling fixture for a power distribution cabinet accessory, the support component 1 includes a positioning seat 1. The upper parts of the two U-shaped connecting seats are slidably connected to the positioning seat 1. The two positioning seats 1 are connected by a connecting rod 1 that is fixed symmetrically at the front and rear. The two positioning seats 1 are connected by a T-shaped piece 1 that slides through the sides of the two positioning seats 1 that are close to each other through a spring 1. The end of the T-shaped piece 1 located inside the positioning seat 1 is fixed with a toothed plate 5.

[0013] In the aforementioned drilling fixture for a power distribution cabinet accessory, multiple positioning components are provided. The positioning components include an adjusting seat, on which the adjusting seat slides left and right together on two connecting rods. The top wall of the adjusting seat is provided with four slide rails in a cross shape. Slide blocks slide on the slide rails via springs. Each of the four slide blocks is hinged with a stabilizing rod. The ends of the four stabilizing rods away from the slide blocks are hinged together with an annular drill sleeve.

The positioning component 32 is positioned above and below the support member 42 to prevent deformation of the door panel during drilling. The second locking component 43 is used to lock the position of the support member 42.

[0041] Reference Figure 3 and Figure 6 The support component 2 41 includes a positioning seat 2 411. The two U-shaped connecting seats 21 are slidably connected to the positioning seat 2 411 at their lower parts. The two positioning seats 2 411 are connected by a connecting rod 2 412 that is fixed symmetrically at the front and rear. The two positioning seats 2 411 are close to each other on one side, and a T-shaped piece 2 413 is slidably passed through by a spring 3. The end of the T-shaped piece 2 413 located inside the positioning seat 2 411 is fixedly connected to a toothed plate 6.

[0042] Reference Figure 3 , Figure 6 and Figure 7 Locking component 2 43 includes toothed plate 3 432. The bottom of positioning seat 2 411 is slidably connected to toothed plate 3 432 that is compatible with toothed plate 6. The bottom walls of the two toothed plates 3 432 are fixedly connected to an upper push frame 431. The bottom wall of support member 42 is symmetrically provided with locking member 2 433 that slides through spring 4. Locking member 2 433 corresponds to connecting rod 2 412. The support member 42 has a detachable rubber pad 2 434 installed above connecting rod 2 412 inside.

[0043] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9Both the adjusting seat 321 and the support 42 have holes in the middle for the drill bit to pass through. The toothed plate 34 is fixed to the bottom wall of the positioning seat 311, and the toothed plate 44 is fixed to the top wall of the positioning seat 411. The toothed plates 34 and 44 are respectively meshed with the left and right side walls of the same gear shaft 23. The bottom wall of the locking part 333 and the top wall of the rubber pad 334 are both arc-shaped to match the connecting rod 312. The top wall of the locking part 433 and the bottom wall of the rubber pad 434 are both arc-shaped to match the connecting rod 412.

[0044] Before drilling, the specific operation of adjusting the positioning mechanism 3 according to the actual drilling distance requirements is as follows: First, adjust and slide multiple adjusting seats 321 left and right on the connecting rod 312 to the specified position required by the actual drilling distance. At this time, the spring 2 connected between the locking part 333 and the adjusting seat 321 is in a contracted state. The locking part 333 is away from the connecting rod 312 and will not interfere with the movement of the adjusting seat 321.

[0045] After all the adjustment seats 321 have moved to the specified positions, hold the pressing frame 331, align the toothed plate 332 with the positioning seat 311, and press the pressing frame 331 down. The toothed plate 332 enters the corresponding positioning seat 311, and the T-shaped part 313 and the toothed plate 5 are squeezed and slide out of the positioning seat 311. The spring 1 performs adaptive extension and contraction.

[0046] The two left and right facing sections of the positioning seat 311 correspond to the locking element 333 below. When the pressing frame 331 moves down, it presses the top walls of the locking elements 333 on multiple adjusting seats 321 in batches. The spring 2 stretches, and the locking element 333 moves down towards the corresponding connecting rod 312 until the locking element 333 and the rubber pad 334 are in close contact with the connecting rod 312 from both the top and bottom directions (e.g., Figure 5 As shown in the figure, the positions of the adjusting seat 321 and the connecting rod 312 are relatively fixed.

[0047] T-shaped part 313 is subjected to the restoring force of spring 1, which makes toothed plate 5 and toothed plate 332 fit tightly together, restricting the position of toothed plate 332 in positioning seat 311. Therefore, the positions of pressing frame 331 and positioning seat 311 are relatively fixed, and the positioning mechanism 3 forms a stable whole.

[0048] It should be noted that the connecting rod 312 can be marked with graduations as needed, and an observation hole is provided in the middle of the front side wall of the adjusting seat 321. The precise graduation at the center of the adjusting seat 321 can be observed through the observation hole, which is beneficial for accurately adjusting the position of the adjusting seat 321. A rubber pad can be fitted to the contact surface between the locking element 333 and the connecting rod 312 to increase friction.

[0049] Before drilling, the specific operation of adjusting the support mechanism 4 according to the actual drilling distance requirement or the position change of the adjusting seat 321 is as follows: First, slide the multiple support parts 42 left and right on the connecting rod 2 412 to the specified position required by the actual drilling distance or the position corresponding to the adjusting seat 321. At this time, the spring 3 connected between the locking part 2 433 and the support part 42 is in a contracted state. The locking part 2 433 is away from the connecting rod 2 412 and will not interfere with the movement of the support part 42.

[0050] After all the supporting parts 42 have moved to the designated positions, hold the push frame 431 and align the toothed plate 3 432 with the positioning seat 2 411. Move the push frame 431 closer to the positioning seat 2 411 until the toothed plate 3 432 enters the corresponding positioning seat 2 411. The T-shaped part 2 413 and the toothed plate 6 are squeezed and slide outward from the positioning seat 2 411. The spring 3 adapts to the expansion and contraction.

[0051] The two left and right facing sections of the upper push frame 431 correspond to the upper locking element 433. When the upper push frame 431 moves upward, it pushes the bottom walls of multiple locking elements 433 in batches, stretching the spring 4. The locking elements 433 move upward toward the corresponding connecting rod 412 until the locking elements 433 and the rubber pad 434 are in close contact with the connecting rod 412 from both the top and bottom directions (e.g., Figure 7 As shown in the figure, the positions of the support member 42 and the connecting rod 412 are relatively fixed.

[0052] T-shaped part 413 is subjected to the restoring force of spring 3, which makes toothed plate 6 and toothed plate 3 432 fit tightly together, restricting the position of toothed plate 3 432 in positioning seat 411. Therefore, the upper push frame 431 and positioning seat 2 411 are relatively fixed, and the supporting mechanism 4 forms a stable whole.

[0053] It should be noted that the connecting rod 412 can be marked with graduations as needed, and the front side wall of the support 42 has an observation hole, through which the precise graduation at the center of the support 42 can be observed, which is beneficial for accurately adjusting the position of the support 42. A rubber gasket can be fitted to the contact surface between the locking part 433 and the connecting rod 412 to increase friction.

[0054] Before drilling, the positioning mechanism 3 and the supporting mechanism 4, which form an integral whole, are aligned vertically (e.g., Figure 3As shown), the positioning mechanism 3 and the supporting mechanism 4 are quickly connected by two symmetrically distributed connecting mechanisms 2. The specific operation is as follows: Positioning seat 1 311 and positioning seat 2 411 are slid simultaneously into the left and right facing sections of the corresponding U-shaped connecting seat 21. Positioning seat 1 311 drives the corresponding toothed plate 2 34 to move downwards and closer to the gear shaft 23. Positioning seat 2 411 drives the corresponding toothed plate 44 to move upwards and closer to the gear shaft 23, until both toothed plate 2 34 and toothed plate 44 are engaged with the side wall of the gear shaft 23 (as shown). Figure 9 As shown in the initial state), the quick assembly of the connecting mechanism 2, the positioning mechanism 3, and the supporting mechanism 4 is completed at this time.

[0055] During the meshing adjustment of gear plate 34 and gear plate 44 with the side wall of gear shaft 23, gear shaft 23 drives ratchet 24 to rotate. When ratchet 24 rotates, it pushes limit key 26 to rotate. Torsion spring rod rotates to adapt to the change of limit key 26, and then drives limit key 26 to reset. After ratchet 24 rotates, it is restricted by the reset of limit key 26, and the positions of gear plate 34 and gear plate 44 are relatively stable.

[0056] After the connecting mechanism 2, positioning mechanism 3 and supporting mechanism 4 are assembled, the U-shaped connecting seat 21 drives the positioning mechanism 3 and supporting mechanism 4 to move downward, aligning the mounting hole 22 with the support column 12. The support column 12 and the U-shaped connecting seat 21 are then engaged, thus completing the assembly process of the mounting mechanism 1, connecting mechanism 2, positioning mechanism 3 and supporting mechanism 4.

[0057] The instruction manual indicates that this invention is a portable assembly and disassembly kit. Each component is small and lightweight, making it easy to carry. After arriving at the work site, the components should be assembled in a portable manner according to the above-described scheme before drilling operations can be performed.

[0058] The specific steps for drilling are as follows: First, place the support 11 on a horizontal surface. Then, pass the distribution cabinet door panel to be processed between the positioning mechanism 3 and the supporting mechanism 4. The door panel is supported by the support roller 13. By turning the left knob 25 counterclockwise and the right knob 25 clockwise, the knob 25 drives the corresponding ratchet 24 and gear shaft 23 to rotate. The rotation of the gear shaft 23 drives the corresponding toothed plate 34 to move downward and the toothed plate 44 to move upward (e.g., ...). Figure 9 As shown, the positioning mechanism 3 and the supporting mechanism 4 move closer to each other. The bottom wall of the adjusting seat 321 and the top wall of the supporting member 42 are circular rubber pads that clamp the door panel to be processed. The supporting member 42 supports the door panel to prevent the door panel from deforming due to excessive drilling pressure during drilling, which would affect the drilling effect.

[0059] After clamping is completed, drilling is performed. The operator holds the drill and aligns it with the annular drill sleeve 323, and drills downwards to the position that has been positioned by the adjusting seat 321. The adjusting seat 321, which has been pre-adjusted for the drilling hole spacing, can modularly and synchronously position multiple holes, which helps to improve the positioning efficiency.

[0060] When the annular drill sleeve 323 is subjected to a downward force, it causes multiple stabilizing rods 322 to change from a nearly vertical state to a nearly horizontal state. As the multiple stabilizing rods 322 tilt, they rotate with the slide and the annular drill sleeve 323 to adapt to the change. The slide slides on the slide rail, and the multiple slides slide from a state close to each other to a state far apart from each other. The spring 5 is gradually compressed to adapt to the change. The stabilizing rods 322 support the annular drill sleeve 323 to maintain a vertical drilling path throughout the downward movement process, reducing errors and hole position deviations caused by manual positioning and opening, and ensuring the accuracy of drilling.

[0061] After a single hole is drilled, the operator moves the drill rig upwards and then to the next annular drill sleeve 323 to drill. The previous annular drill sleeve 323 moves upwards and resets. The specific reset action is as follows: the downward pressing action is released, the spring returns to its original position, the slide block slides in the slide rail and resets, the stabilizing rod 322 resets from a near-horizontal state to a near-vertical state, driving the annular drill sleeve 323 to move upwards and reset. The stabilizing rod 322 rotates between the slide block and the annular drill sleeve 323 to adapt to the change.

[0062] It should be noted that when drilling multiple rows of holes in a single distribution cabinet door panel, after drilling one row of holes, the door panel is released by turning knob 25 to adjust the position of adjusting seat 321 and support member 42. After moving the door panel, the position of adjusting seat 321 and support member 42 is adjusted by turning knob 25 to clamp the door panel, and then drilling of the next row of holes can begin. When drilling holes in the same position in multiple distribution cabinet door panels in batches, the positioning mechanism 3 and support mechanism 4 do not need to be adjusted or changed, which helps to improve the efficiency of batch drilling.
