Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing, and specifically relates to a hole-expanding device for the production of power distribution cabinets. Background Technology

[0002] A distribution cabinet is an electrical device used for centralized control and distribution of electrical energy. It typically consists of a cabinet, switching devices, protective devices, measuring instruments, busbars, etc.

[0003] During the reaming process of a distribution cabinet, a large amount of metal shavings are generated. If not cleaned in time, the shavings will accumulate on the surface of the reaming table. When clamping the cabinet again, the bottom of the distribution cabinet will come into contact with the shavings. Due to the presence of the shavings, the distribution cabinet cannot be completely fitted to the reaming table, resulting in uneven clamping. Uneven clamping will cause the position of the distribution cabinet to shift during reaming, resulting in inaccurate hole position. This phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content

[0024] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-6 The present invention provides a technical solution: a hole-expanding device for the production of power distribution cabinets, including a workbench 1, a first mounting plate 101 fixedly installed at one end of the workbench 1, a second mounting plate 102 fixedly installed at the other end of the workbench 1, and a moving mechanism 2 provided on the first mounting plate 101, the moving mechanism 2 being adapted to ensure that the tool or workpiece moves along a precise linear trajectory.

[0026] The moving mechanism 2 includes a first motor 203 fixedly installed on the side of the first mounting plate 101. The first fixed plate 201 is fixedly installed inside the first mounting plate 101. The output end of the first motor 203 passes through the first fixed plate 201. The first motor 203 is threadedly connected to a first lead screw (not shown in the figure). The first lead screw is provided with two sets of screw grooves with opposite helical directions (not shown in the figure). A movable seat (not shown in the figure) is threadedly connected to the first lead screw.

[0027] A first movable rod 204 is fixedly installed on the first fixed plate 201. The first movable rod 204 has two sets. Each set of the first movable rod 204 is provided with a sliding block 205 that is slidably connected. The two sets of sliding blocks 205 are fixedly connected to the movable seat. A fixed mounting plate (not shown in the figure) is fixedly installed at the bottom of the two sets of sliding blocks 205. A first cylinder 206 is fixedly installed at the bottom of the fixed mounting plate. A second motor 207 is fixedly installed at the output end of the first cylinder 206. A drill bit 209 is fixedly installed at the output end of the second motor 207.

[0028] After the first motor 203 starts, it begins to rotate. Since its output end is threadedly connected to the first lead screw, the rotational motion of the first motor 203 is transmitted to the first lead screw, driving the first lead screw to rotate around its own axis. The first lead screw is provided with two sets of helical grooves with opposite directions of rotation. The two sets of helical grooves with opposite directions of rotation allow the two sets of sliding blocks 205 that cooperate with the two sets of first lead screws to make linear movements in relative or opposite directions. The second motor 207, which is fixedly installed below the first cylinder 206, starts to rotate when working. The drill bit 209, which is fixedly installed at its output end, will rotate together with the second motor 207. Combined with the horizontal linear movement achieved by the first motor 203 and the first lead screw and the vertical position adjustment achieved by the first cylinder 206, the drill bit 209 can move precisely to the designated position and rely on its own rotation to perform hole enlargement operation on the workpiece, ensuring that the positional accuracy of the drilling meets the requirements, and realizing the completion of the corresponding processing task by moving along a precise linear trajectory.

[0029] Telescopic components 3 are provided on both the first mounting plate 101 and the second mounting plate 102. The telescopic components 3 have two sets. The telescopic components 3 include a second cylinder 301 fixedly mounted on the first mounting plate 101. The telescopic rod of the second cylinder 301 passes through the first mounting plate 101. A second movable rod 302 is slidably connected to the first mounting plate 101. One end of the second movable rod 302 passes through the first mounting plate 101. There are two sets of second movable rods 302. An L-shaped fixed seat 303 is fixedly mounted on the first mounting plate 101. The second movable rod 302 is slidably connected in the fixed seat 303. At the same time, one end of the second movable rod 302 passes through the fixed seat 303. A convex block 304 is fixedly mounted on the fixed seat 303. The telescopic end of the second cylinder 301 is fixedly connected to a fixed rod 305. The fixed rod 305 is slidably connected in the convex block 304. The top end of the fixed rod 305 is fixedly connected to a pressure plate 306. At the same time, the top ends of the two sets of second movable rods 302 are fixedly connected to the pressure plate 306.

[0030] When rotating, the sliding seat 403 moves linearly along the axis of the second lead screw 402 under the action of the screw thread. The second cylinder 301 starts to work, and its internal power drive mechanism causes the telescopic rod to extend outward. Since the fixed rod 305 is firmly fixed to the telescopic end of the second cylinder 301, the fixed rod 305 will move linearly downward along the trajectory defined by the convex block 304 in sync with the telescopic rod. The sliding connection of the convex block 304 to the fixed rod 305 effectively restricts its direction of movement and avoids deviation. The sliding connection between the second movable rod 302 and the first mounting plate 101 and the fixed seat 303 ensures the linearity and stability of the movement of the pressure plate 306, so that the pressure plate 306 can move accurately according to the preset downward pressing path.

[0031] Displacement components 4 are provided on both sides of the workbench 1. There are two sets of displacement components 4. Each displacement component 4 includes a third motor 401 fixedly installed on the second mounting plate 102. The output end of the third motor 401 passes through the second mounting plate 102. The output end of the third motor 401 is threadedly connected to a second lead screw 402. A sliding seat 403 is threadedly connected to the second lead screw 402.

[0032] When the third motor 401 starts, its output end begins to rotate, and the second lead screw 402 rotates.

[0033] Both sets of second mounting plates 102 are equipped with lifting components 5. The lifting component 5 on the left is defined as the first lifting component, and the lifting component 5 on the right is defined as the second lifting component (see reference). Figure 1The first lifting assembly and the second lifting assembly have similar structures. The lifting assembly 5 includes a base 501 mounted on the second mounting plate 102. A third cylinder 502 is fixedly mounted on the base 501. A rack 503 is fixedly mounted on the telescopic end of the third cylinder 502. The rack 503 has only a small section of teeth (not shown in the figure).

[0034] A cleaning component 6 is provided on the sliding seat 403. The cleaning component 6 includes a second fixed plate 602 fixedly installed on the sliding seat 403. A third movable rod 601 is connected to the bearing inside the second fixed plate 602. A gear 504 is fixedly connected to the top end of the third movable rod 601. When the third cylinder 502 pushes the rack 503 to a designated position, when the gear 504 moves close to the rack 503, a small section of teeth on the rack 503 will mesh with the gear 504.

[0035] Two sets of second fixing blocks 605 are fixedly installed on the third movable rod 601. A brush plate 603 is fixedly installed between the two sets of second fixing blocks 605. A cloth plate 604 is also fixedly installed between the two sets of second fixing blocks 605. A round rod 606 is fixedly installed on the side of the second fixing block 605. Four sets of grooves (not shown in the figure) are opened on the second fixing plate 602. The round rod 606 can rotate with the third movable rod 601 to engage in the groove. Round holes (not shown in the figure) are opened on both sides of the inner wall of the groove. A spring 608 is fixedly installed at one end of the inner wall of the round hole. A protrusion 607 is fixedly installed at the top of the spring 608. The round rod 606 is adapted to rotate to squeeze the protrusion 607 to squeeze the spring 608 into the round hole. When the round rod 606 passes the two sets of protrusions 607, the protrusions 607 are extended again by the action of the spring 608 to restrict the round rod 606.

[0036] In the initial state, the second lifting component is moved upward by the action of the third cylinder 502, so that the rack 503 of the second lifting component moves to the designated position, and the cleaning component 6 is initially located to the left of the first lifting component.

[0037] During cleaning, the third motor 401 drives the second lead screw 402 to rotate, causing the cleaning component 6 to move to the right and perform preliminary cleaning on the surface of the worktable 1 through the brush plate 603. When the gear 504 contacts and meshes with the rack 503 of the second lifting component, and when the gear 504 passes over the teeth on the rack 503, the third movable rod 601 completes a 180-degree rotation. At this time, the brush plate 603 and the cloth plate 604 are switched, and the cloth plate 604 is in contact with the surface of the worktable 1.

[0038] At this time, the third cylinder 502 of the second lifting component drives the rack 503 to move down, while the third cylinder 502 of the first lifting component drives the rack 503 to move up to the designated position. Then the third motor 401 rotates in the opposite direction again, driving the cleaning component 6 to move to the left. The cloth plate 604 further cleans the surface of the workbench 1. When the gear 504 of the first lifting component contacts and meshes with the rack 503, and the gear 504 passes over the teeth on the rack 503, the third movable rod 601 completes a 180-degree reverse rotation, thus returning to the state where the brush plate 603 is at the lower end and the cloth plate 604 is at the upper end.

[0039] It should be noted that when the gear 504 drives the third movable rod 601 to rotate 180 degrees, the round rod 606 fixedly installed on the second fixed block 605 is pressed against the two sets of protrusions 607, and the protrusions 607 press against the spring 608. When the round rod 606 passes the two sets of protrusions 607, the protrusions 607 are extended again by the action of the spring 608 to restrict the round rod 606.

[0040] At the same time, when gear 504 drives the third movable rod 601 to rotate 180 degrees in the opposite direction, the round rod 606 will squeeze the two sets of protrusions 607 again and disengage from them, thereby flipping into the opposite protrusion 607 for limiting.

[0041] Working principle:

[0042] When the first motor 203 starts, the rotational motion of its output end is transmitted to the first lead screw. Since the first lead screw has two sets of spiral grooves with opposite directions of rotation, the two sets of sliding blocks 205 that cooperate with the first lead screw will make linear motion in relative or opposite directions, thereby realizing the precise movement of the movable seat in the horizontal direction. At the same time, the first cylinder 206 can realize the vertical position adjustment of the fixed mounting plate, thereby driving the second motor 207 and the drill bit 209 to move up and down.

[0043] Furthermore, the second motor 207 starts to rotate, and the drill bit 209 fixedly installed at its output end rotates accordingly. Combined with the horizontal and vertical movements, the drill bit 209 can move precisely to the designated position to perform hole enlargement operation on the workpiece, ensuring that the positional accuracy of the drilling meets the requirements.

[0044] When the second cylinder 301 is working, its telescopic rod extends outward, and the fixed rod 305 moves downward in a straight line along the trajectory defined by the convex block 304 in sync with the telescopic rod. At the same time, the sliding connection between the second movable rod 302 and the first mounting plate 101 and the fixed seat 303 ensures the linearity and stability of the movement of the pressure plate 306, so that the pressure plate 306 presses down accurately and fixes the workpiece on the worktable 1.

[0045] In the initial state, the rack 503 of the second lifting component moves upward to the designated position under the action of the third cylinder 502. The cleaning component 6 is on the left side of the first lifting component. During cleaning, the third motor 401 drives the second lead screw 402 to rotate, causing the cleaning component 6 to move to the right. The brush plate 603 performs preliminary cleaning on the surface of the worktable 1.

[0046] When gear 504 contacts and meshes with rack 503 of the second lifting assembly, and gear 504 passes over the teeth on rack 503, the third movable rod 601 completes a 180-degree rotation, the positions of brush plate 603 and cloth plate 604 are reversed, and cloth plate 604 contacts the surface of worktable 1.

[0047] The third cylinder 502 of the second lifting assembly drives the rack 503 to move down, and the third cylinder 502 of the first lifting assembly drives the rack 503 to move up to the designated position. Then the third motor 401 rotates in the opposite direction again, driving the cleaning assembly 6 to move to the left, and the cloth plate 604 further cleans the surface of the workbench 1.

[0048] When the gear 504 of the first lifting assembly contacts and meshes with the rack 503 and rotates, and the gear 504 passes over the teeth on the rack 503, the third movable rod 601 completes a 180-degree reverse rotation and returns to the initial state where the brush plate 603 is at the lower end and the cloth plate 604 is at the upper end.

[0049] Throughout the entire process, through the coordinated action of various components, the device can achieve precise hole enlargement machining of the power distribution cabinet, effectively clean the worktable 1 before and after machining, and ensure the fixation effect of the workpiece, thereby improving work efficiency and machining quality.
