Description

Technical Field

[0001] The invention relates to the technical field of drilling, in particular to a production and processing device for an electric energy metering box. Background Art

[0002] The electric energy meter box usually contains electrical components such as electric energy meters, circuit breakers, and mutual inductors, and needs to connect incoming and outgoing cables. In order to facilitate the laying of communication cables and other power cables in and out, knock-out holes will be reserved or set on the box during the production and processing of the electric energy meter box.

[0003] The patent with publication number CN219025986U discloses a drilling tool for producing an electric energy metering box, comprising a processing table, an inverted U-shaped bracket is fixedly installed on the top of the processing table, an inverted U-shaped lifting plate is slidably installed on the inner side of the inverted U-shaped bracket, rotating grooves are provided on the inner walls of both sides of the inverted U-shaped lifting plate, rotating blocks are rotatably installed in the two rotating grooves, and the same rectangular rod is fixedly installed on one side of the two rotating blocks, a plurality of first bevel gears are provided on the outer movable sleeve of the rectangular rod, and second bevel gears are meshed on the plurality of first bevel gears, and rotating rods are fixedly installed on the bottom ends of the plurality of second bevel gears, and a drill bit is fixedly installed on the bottom end of the rotating rod, a vertical hole is provided on the inverted U-shaped lifting plate, a rectangular horizontal plate is fixedly installed in the vertical hole, and a plurality of movable plates are slidably installed in the vertical hole, and the spacing between the movable plates is adjusted by pushing the movable plate to move horizontally, so that the movement of the rotating rod drives the second bevel gear and the drill bit to move, thereby the spacing between the drill bits can be adjusted to meet different drilling requirements.

[0004] Although the above-mentioned drilling tool can adjust the spacing between the drill bits, the space for the drill bit to move up and down is limited. The electric energy meter box can generally only be placed horizontally on the processing table for drilling. When the electric energy meter box needs to be placed vertically to drill other sides, the above-mentioned drilling tool is not applicable. Even if the space for the drill bit to move up and down is increased, the drill surface of the vertically placed electric energy meter box will be much higher than the table top of the processing table, which will affect people's observation of the real-time drilling situation, making it difficult to make real-time adjustments.

[0016] Beneficial Effects

[0017] 1. The present invention arranges the first bracket, the placement bracket and the limit bracket, so that the top surface of the electric energy meter box is at the height of the processing table regardless of whether it is placed horizontally or vertically, which is convenient for drilling holes on all sides of the electric energy meter box, and ensures that the drilling surface can quickly adapt and adjust to a fixed processing table height when placed horizontally or vertically, which is convenient for people to observe the drilling situation in real time, and there is no need to constantly adjust the height of the processing table each time the surface is changed for drilling, thereby enhancing the flexibility and scope of application of the production line.

[0018] 2. The present invention utilizes the positions of two positioning blocks to accurately determine the forward and backward movement position of the drilling machine, thereby avoiding the height difference between the drilling machine and the drilling position, which makes it difficult to accurately control the drilling position when moving forward and backward. At the same time, the positioning block can also press the electric energy meter box when drilling to prevent the electric energy meter box from shaking up and down when drilling. When the slide returns to its initial position, the electromagnet is automatically energized to attract the magnetic block, so that the positioning block slides back to the initial position along the sensing rod and no longer blocks the electric energy meter box, thereby facilitating the removal and placement of the electric energy meter box.

[0019] 3. The present invention not only realizes the automatic opening and closing of the drilling machine through the cooperation between the drilling machine and the rotating rod, and the cooperation between the first contact switch and the first contact block, but also ensures that the drilling machine will be powered on and started only when the first contact switch is in contact with the first contact block, that is, the drilling machine is correctly and firmly mounted on the mounting frame and drilling downwards. The drilling machine will not be started due to misoperation during normal hand-held picking and placing, thereby enhancing the safety of the operation process.

[0020] 4. When the support plate drives the drilling machine to drill downward, the present invention limits the positioning block by moving the clamping rod downward and clamping it into the circular hole, so as to prevent the strong vibration generated during drilling from causing the positioning block to rock back and forth on the sensing rod, thereby avoiding the electric energy metering box in contact with the positioning block from rocking back and forth. At the same time, the trapezoidal clamping block is clamped in the rectangular groove of the drilling machine, and the second clamping frame is squeezed to move inward to clamp the roller. The two work together to prevent the slide from being unable to move back and forth on the drilling machine at will. In this way, the stability during drilling is improved, thereby improving the accuracy of drilling.

[0021] 5. The present invention utilizes the cooperation between the second contact switch and the rotating frame and the cooperation between the second contact switch and the second contact block, so that when the drilling machine is drilling downwards, the U-shaped guide rail always maintains a power-on state, so that the slider can stay in the raised position of the U-shaped guide rail, and there is no need to manually grab the slide when drilling. When the drilling machine is completed and reset upward, the U-shaped guide rail automatically cuts off the power, so that the slider can automatically slide backward and reset by pulling the slide by the pull rope.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1: A production and processing device for an electric energy meter box, combined with the attached Figure 1 To Attachment Figure 4 , including a drilling machine 1, the upper part of the drilling machine 1 is slidably connected to a placement rack 2 for placing an electric energy meter box in the up-down direction, a U-shaped groove for vertically placing the electric energy meter box is opened in the middle of the placement rack 2, the front and rear sides between the drilling machine 1 and the placement rack 2 are fixedly connected with first springs 3 symmetrically distributed along the placement rack 2, the drilling machine 1 is slidably connected to a slide 4 in the front-to-back direction, the upper and lower sides of the lower part of the slide 4 are rotatably connected with rollers 5 symmetrically distributed along the slide 4, the rollers 5 roll forward and backward along the drilling machine 1, the upper part of the slide 4 is fixedly connected to an electric push rod 6 symmetrically distributed along the slide 4, a support plate 7 is fixedly connected between the telescopic ends of the symmetrically distributed electric push rod 6, the support plate 7 is placed with three spaced mounting racks 8 from left to right, the mounting rack 8 is slidably connected to a drilling machine 9 in the up-down direction, the drill bit of the drilling machine 9 is set to an inverted cone, and the upper part of the drilling machine 9 is fixedly connected with spring sheets symmetrically distributed along the drilling machine 9. 801, the spring sheet 801 is used to fasten the drilling machine 9 to the support plate 7 and the mounting frame 8 to prevent the drilling machine 9 from moving left and right and up and down at will. The upper part of the mounting frame 8 is threadedly connected with a first bolt 10, and the first bolt 10 is rotatably connected to the adjacent drilling machine 9. The drilling machine 1 is slidably connected to a first bracket 11 symmetrically distributed along the left and right directions of the drilling machine 1. The first bracket 11 is used to limit the placement frame 2. A wedge-shaped surface is provided in the middle of the first bracket 11. The vertically placed electric energy metering box is squeezed and matched with the wedge-shaped surface of the first bracket 11. A second spring 12 is fixedly connected between the first bracket 11 and the drilling machine 1. The drilling machine 1 is slidably connected to a limit frame 13 for limiting the descending height of the placement frame 2 along the up and down directions. The limit frame 13 is located below the placement frame 2. A second bolt 131 is threadedly connected to the side of the drilling machine 1 close to the limit frame 13, and the second bolt 131 is rotatably connected to the limit frame 13.

[0037] When the electric energy meter box needs to be placed horizontally for punching, people place the electric energy meter box horizontally on the placement rack 2. At this time, since the placement rack 2 is limited by the first bracket 11, the placement rack 2 will not drop. When the electric energy meter box needs to be placed vertically for punching, people place the electric energy meter box vertically in the U-shaped groove of the placement rack 2. At this time, since the electric energy meter box squeezes the wedge-shaped surface of the first bracket 11, the first bracket 11 slides outward, the second spring 12 is compressed, and the first bracket 11 no longer limits the placement rack 2. The placement rack 2 can be dropped to the limiting bracket 13, the first spring 3 is compressed, and the height of the limiting bracket 13 is adjusted in advance by screwing the second bolt 131, so that the top surface of the subsequent electric energy meter box is at the same position height regardless of whether it is placed horizontally or vertically;

[0038] After the electric energy meter box is placed, the first bolt 10 is screwed forward and backward according to the required drilling size, so that the first bolt 10 drives the drilling machine 9 to move up and down relative to the mounting frame 8. Since the drill bit of the drilling machine 9 is set to an inverted cone, the larger the hole to be drilled, the lower the drill bit of the drilling machine 9 is adjusted. After adjustment, the mounting frame 8 is installed on the support plate 7. Under the action of the spring sheet 801, the drilling machine 9 is fastened to the support plate 7 and the mounting frame 8. Then, according to the specific position of the hole to be drilled, people push the slide 4 back and forth. Under the rolling action of the roller 5, the slide 4 drives the electric push rod 6, the support plate 7, the mounting frame 8, the spring sheet 801, the drilling machine 9 and the first bolt 10 to move forward and backward synchronously. Then, the mounting frame 8 is pushed left and right with force, so that the electric push rod 6, the support plate 7, the spring sheet 801, the drilling machine 9 and the first bolt 10 move left and right synchronously. After front, back, left and right adjustments, the drilling machine 9 is positioned at the drilling position.

[0039] Then, the drilling machine 9 is started to rotate the drill bit of the drilling machine 9, and the telescopic rod of the electric push rod 6 is controlled to shorten, thereby driving the support plate 7 to move downward, and the support plate 7 drives the drilling machine 9 to move downward, thus completing the drilling operation;

[0040] After completing the drilling, turn off the drilling machine 9 and remove the mounting frame 8 together with the drilling machine 9 from the support plate 7, then push the slide 4 backward to reset, and finally take away the drilling-finished electric energy meter box. When taking away the vertically placed electric energy meter box, the second spring 12 resets and drives the first bracket 11 to slide inward and reset, and the first spring 3 resets and drives the placement frame 2 to slide upward and reset.

[0041] In summary, the present invention limits the placement rack 2 at a certain height through the first bracket 11, which is used to place the energy meter box horizontally, and then squeezes the first bracket 11 when the energy meter box is placed vertically, thereby releasing the limitation on the placement rack 2, so that the placement rack 2 can be lowered, increasing the placement space, and is used to place the energy meter box vertically. By adjusting the height of the limit rack 13, the top surface of the energy meter box is at the height of the processing table regardless of whether it is placed horizontally or vertically. In this way, it is convenient to drill holes on all sides of the energy meter box, and it is ensured that the drilling surface can quickly adapt and adjust to a fixed height when placed horizontally or vertically. There is no need to continuously adjust the height of the processing table each time the surface is changed and holes are drilled, thereby enhancing the flexibility and applicability of the production line.

[0042] Embodiment 2: Based on embodiment 1, Figure 5 To Attachment Figure 6, also includes sensing rods 14 symmetrically distributed along the drilling machine 1, the sensing rods 14 are fixedly connected to the inner side of the slide 4, the sensing rods 14 are slidably connected along the front-back direction with a positioning block 15 for limiting the top surface of the electric energy metering box and positioning the drilling position, a tension spring 16 is fixedly connected between the sensing rods 14 and the adjacent positioning block 15, the rear side of the drilling machine 1 is fixedly connected with sensing switches 17 symmetrically distributed along the drilling machine 1, the sensing switches 17 are in contact with the rear ends of the adjacent sensing rods 14, a magnetic block 18 is fixedly connected to the inner side of the positioning block 15, the rear side of the drilling machine 1 is fixedly connected with electromagnets 19 symmetrically distributed along the drilling machine 1, the sensing switch 17 is electrically connected to the electromagnet 19 through a control module, and when the electromagnet 19 is energized, the electromagnet 19 is magnetically attracted to the adjacent magnetic block 18.

[0043] The slide 4 moves forward and backward, driving the sensing rod 14, the positioning block 15, the tension spring 16 and the magnetic block 18 to move forward and backward. When the sensing rod 14 moves forward and disconnects from the sensing switch 17, the sensing switch 17 controls the electromagnet 19 to be powered off through the control module. After the magnetic block 18 is separated from the electromagnet 19, the tension spring 16 in the stretched state resets and drives the positioning block 15 to slide forward along the sensing rod 14, so that the straight line formed by the two positioning blocks 15 and the straight line formed by the drill bits of the three drilling machines 9 are on the same vertical plane. In this way, when the slide 4 drives the positioning block 15 to move forward and backward on the plane to be drilled in the electric energy metering box, people can accurately judge the position of the drilling machine 9 moving forward and backward according to the positions of the two positioning blocks 15.

[0044] When the sensing rod 14 moves backward and contacts the sensing switch 17, the sensing switch 17 controls the electromagnet 19 to be energized through the control module. Under the action of magnetic attraction, the magnetic block 18 moves backward and is attracted to the electromagnet 19, thereby driving the positioning block 15 to slide backward along the sensing rod 14, and the tension spring 16 is stretched, so that the positioning block 15 no longer blocks the electric energy meter box;

[0045] To sum up, the present invention utilizes the positions of the two positioning blocks 15 to accurately determine the forward and backward movement position of the drilling machine 9, thereby avoiding the height difference between the drilling machine 9 and the drilling position, which makes it difficult to accurately control the drilling position when moving forward and backward. At the same time, the positioning block 15 can also press the electric energy meter box when drilling to prevent the electric energy meter box from shaking up and down when drilling. When the slide 4 returns to its initial position, the electromagnet 19 is automatically energized to attract the magnetic block 18, so that the positioning block 15 slides backward along the sensing rod 14 back to the initial position, no longer blocking the electric energy meter box, and facilitating the removal and placement of the electric energy meter box.

[0046] Combined with Figure 7 To Attachment Figure 8, and also includes a rotating rod 20 symmetrically distributed along the front and back of the slide 4, the rotating rod 20 is rotatably connected to the upper part of the slide 4, and a first torsion spring 21 symmetrically distributed along the left and right of the rotating rod 20 is fixedly connected between the rotating rod 20 and the slide 4. A first contact switch 22 is fixedly connected to the rotating rod 20, and the first contact switch 22 is electrically connected to the drilling machine 9 through the control module. The front and rear sides of the drilling machine 9 are fixedly connected with first contact blocks 221, and the first contact blocks 221 are in contact with and cooperate with the adjacent first contact switches 22.

[0047] When the drilling machine 9 moves downward, it squeezes the rotating rod 20 to rotate, thereby driving the first contact switch 22 to rotate toward the side close to the drilling machine 9, and the first torsion spring 21 is deformed, so that the first contact switch 22 contacts the first contact block 221, and the first contact switch 22 is automatically started by the drilling machine 9 through the control module. When the drilling machine 9 moves upward, it no longer squeezes the rotating rod 20, and the first torsion spring 21 resets to drive the rotating rod 20 to reverse, thereby driving the first contact switch 22 to rotate toward the side away from the drilling machine 9, so that the first contact switch 22 is disengaged from the first contact block 221, and the drilling machine 9 is automatically turned off;

[0048] To sum up, the present invention not only realizes the automatic opening and closing of the drilling machine 9 through the cooperation between the drilling machine 9 and the rotating rod 20, and the cooperation between the first contact switch 22 and the first contact block 221, but also ensures that the drilling machine 9 is powered on and started only when the first contact switch 22 is in contact with the first contact block 221, that is, the drilling machine 9 is correctly and firmly mounted on the mounting frame 8 and drilling downwards. The drilling machine 9 will not be started due to misoperation during normal hand-held taking and placing, thereby enhancing the safety of the operation process.

[0049] Combined with Fig. 9 To Attachment Fig.10, and also includes a clamping rod 23 symmetrically distributed along the slide 4, the clamping rod 23 is slidably connected to the slide 4 in the up and down direction, a third spring 24 is fixedly connected between the clamping rod 23 and the slide 4, and a trapezoidal clamping block 25 is slidably connected to the clamping rod 23 in the left and right directions. Rectangular grooves are provided on the left and right sides of the top of the drilling machine 1. The trapezoidal clamping block 25 moves downward and is embedded in the rectangular groove of the drilling machine 1 under the extrusion of the drilling machine 1 to prevent the slide 4 from being unable to move forward and backward on the drilling machine 1 at will. A fourth spring 26 is fixedly connected between the trapezoidal clamping block 25 and the adjacent clamping rod 23, and a circular hole 261 is provided on the positioning block 15. The positioning block 15 slides forward along the sensing rod 14 until the circular hole 261 is located directly below the clamping rod 23, and the support The support plate 7 moves downward to drive the clamping rod 23 to be clamped into the circular hole 261, which is used to limit the positioning block 15. The slide 4 slides in the left and right directions with a second clamping frame 27 connected and symmetrically distributed along the slide 4. The upper and lower sides of the second clamping frame 27 respectively limit the adjacent upper and lower rollers 5. The outer side of the support plate 7 is fixed with a guide frame 28 symmetrically distributed along the support plate 7. The guide rail of the guide frame 28 is composed of a vertical long rail on the upper side, a vertical short rail on the lower side, and an inclined rail connecting the vertical long rail and the vertical short rail. When the guide frame 28 moves downward, the adjacent second clamping frame 27 is squeezed inward by the inclined rail. When the guide frame 28 moves upward, the adjacent second clamping frame 27 is pulled outward by the inclined rail.

[0050] When the tension spring 16 is reset so that the positioning block 15 slides forward along the sensing rod 14, the positioning block 15 drives the circular hole 261 to move to the bottom of the clamping rod 23. When the support plate 7 moves downward, the support plate 7 drives the clamping rod 23 to move downward and snap into the circular hole 261, thereby limiting the positioning block 15. At the same time, the downward movement of 23 drives the trapezoidal clamping block 25 and the fourth spring 26 to move downward synchronously. Under the squeezing effect of the drilling machine 1, the trapezoidal clamping block 25 slides inward, and the fourth spring 26 is compressed until the trapezoidal clamping block 25 is clamped in the rectangular groove of the drilling machine 1. In addition, the downward movement of the support plate 7 drives the guide frame 28 to move downward. When When the inclined rail of the guide frame 28 moves to the second clamping frame 27, the guide frame 28 squeezes the second clamping frame 27 to move inwards and clamp the roller 5, so that the roller 5 cannot roll freely. When the support plate 7 moves upwards, the support plate 7 drives the clamping rod 23 to move upwards and disengage from the circular hole 261, thereby releasing the limit on the positioning block 15. The upward movement of 23 drives the trapezoidal clamping block 25 and the fourth spring 26 to move upwards synchronously, and the trapezoidal clamping block 25 disengages from the rectangular groove of the drilling machine 1. The fourth spring 26 resets and drives the trapezoidal clamping block 25 to slide outwards. The upward movement of the support plate 7 drives the guide frame 28 to move upwards, thereby pulling the second clamping frame 27 to move outwards and releasing the roller 5.

[0051] To sum up, when the support plate 7 drives the drilling machine 9 to drill downward, the present invention limits the positioning block 15 by moving the clamping rod 23 downward and clamping it into the circular hole 261, so as to prevent the strong vibration generated during drilling from causing the positioning block 15 to shake back and forth on the sensing rod 14, thereby avoiding the electric energy metering box in contact with the positioning block 15 from shaking back and forth. At the same time, the trapezoidal clamping block 25 is clamped in the rectangular groove of the drilling machine 1, and the second clamping frame 27 is squeezed to move inward to clamp the roller 5. The two work together to prevent the slide 4 from being unable to move back and forth on the drilling machine 1 at will. In this way, the stability during drilling is improved, thereby improving the accuracy of drilling.

[0052] Combined with Fig.11 To Attachment Fig.12 , also includes a U-shaped guide rail 29, the U-shaped guide rail 29 is fixedly connected to the rear side of the drilling machine 1, the U-shaped guide rail 29 is slidably connected with a slider 30 in the up and down directions, a pull rope 31 is fixedly connected between the slider 30 and the slide 4 and is symmetrically distributed along the slide 4, a second contact switch 32 is fixedly connected to the top right side of the slide 4, the second contact switch 32 is thick at the top and thin at the bottom, and a rotating frame 33 is rotatably connected to the right side of the support plate 7, the rotating frame 33 contacts the top surface of the second contact switch 32, a second torsion spring 34 is fixedly connected between the rotating frame 33 and the support plate 7 and is symmetrically distributed along the rotating frame 33, a second contact block 35 is fixedly connected to the top of the rotating frame 33, and the second contact block 35 cooperates with the second contact switch 32, the U-shaped guide rail 29 is set as an electromagnet, the second contact switch 32 is electrically connected to the U-shaped guide rail 29 through the control module, the slider 30 is set as a magnet, and when power is turned on, the slider 30 and the U-shaped guide rail 29 are magnetically matched.

[0053] Initially, the second contact switch 32 is turned on, so that the U-shaped guide rail 29 is energized. When the carriage 4 slides forward to the drilling position, the carriage 4 pulls the slider 30 to slide upward along the U-shaped guide rail 29 through the pull rope 31. When the carriage 4 stops, the slider 30 stays at the raised position of the U-shaped guide rail 29, and then the carriage 4 can be released to perform the drilling operation.

[0054] When the support plate 7 moves downward, the support plate 7 drives the rotating frame 33, the second torsion spring 34 and the second contact block 35 to move downward synchronously. During the downward movement, the rotating frame 33 rotates upward due to the squeezing action of the second contact switch 32, and the second torsion spring 34 is deformed, thereby driving the second contact block 35 to rotate toward the side away from the second contact switch 32. When the rotating frame 33 moves downward to be separated from the second contact switch 32, the second torsion spring 34 is reset to drive the rotating frame 33 to reverse, thereby driving the second contact block 35 to rotate toward the side close to the second contact switch 32.

[0055] When the support plate 7 moves upward, the support plate 7 drives the rotating frame 33, the second torsion spring 34 and the second contact block 35 to move upward synchronously. During the upward movement, the second contact block 35 is squeezed by the second contact switch 32 to rotate, thereby driving the rotating frame 33 to rotate downward, the second torsion spring 34 is deformed, the second contact block 35 contacts the second contact switch 32, and the second contact switch 32 is closed, so that the U-shaped guide rail 29 is powered off. Under the action of gravity, the slider 30 slides downward along the U-shaped guide rail 29, thereby pulling the slide 4 to automatically slide backward and reset through the pull rope 31.

[0056] In summary, the present invention utilizes the cooperation between the second contact switch 32 and the rotating frame 33 as well as the cooperation between the second contact switch 32 and the second contact block 35, so that when the drilling machine 9 is drilling downwards, the U-shaped guide rail 29 always maintains a powered state, so that the slider 30 can stay in the raised position of the U-shaped guide rail 29, and there is no need to manually grasp the slide 4 when drilling. When the drilling machine 9 completes drilling and resets upward, the U-shaped guide rail 29 automatically cuts off the power, so that the slider 30 can automatically slide backward and reset by pulling the slide 4 through the pull rope 31.

[0057] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
