Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a relay drilling device. Background Art

[0002] A relay is an electrical control device. When the change of the input quantity (excitation quantity) reaches the specified requirement, it is an electrical appliance that makes the controlled quantity have a predetermined step change in the electrical output circuit. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is usually applied to an automatic control circuit. In fact, it is an "automatic switch" that uses a small current to control a large current operation and plays roles such as automatic regulation, safety protection, and circuit conversion in the circuit.

[0003] Relay drilling usually refers to the operation of drilling certain parts of a relay during the manufacturing or maintenance process of the relay. The purposes of relay drilling are as follows: 1. Install or fix internal components: When it is necessary to install pins, terminals or other connectors, it may be necessary to drill holes in the relay housing or internal bracket; 2. Ventilation and heat dissipation: In order to improve the heat dissipation performance of the relay, sometimes holes are drilled in the housing to increase air circulation. A large amount of debris will be generated during the relay drilling process. If these debris are not cleaned, it will affect the normal progress of the relay drilling work.

[0004] As referring to the prior art CN210789970U, a tapping device for a relay, the relay is placed on the placement plate for tapping (drilling). After the tapping is completed, the placement plate is turned 90 degrees to pour the debris generated by drilling and tapping into the debris collection dish. However, smaller debris will be generated during the relay drilling process, such as plastic debris. These smaller debris will adhere to the placement plate due to static electricity. Just relying on the flipping of the placement plate cannot clean these small debris. Therefore, it will also affect the normal progress of the drilling work. Summary of the Utility Model

[0005] The utility model aims to provide a relay drilling device to solve the problem that smaller debris cannot be cleaned due to adhesion in the prior art.

[0006] To solve the above problems, the utility model provides the following technical solutions:

[0007] A relay drilling device includes a bracket and a drilling machine. The bracket is rotatably connected with a rotating shaft. The rotating shaft is coaxially and fixedly sleeved with a placement plate located directly below the drilling machine. The bracket is also fixedly provided with a servo motor. The servo motor drives a driving gear. The rotating shaft is fixedly sleeved with a driven gear meshing with the driving gear. The bracket is provided with a placement groove. The placement groove is provided with a cylinder. The cylinder drives a scraper located in the placement groove. A groove is provided on one side of the scraper away from the placement plate. The groove is provided with a brush and an air outlet groove. The scraper is provided with a blower for supplying air towards the air outlet groove. The top of the scraper and the top of the brush are both on the same horizontal plane as the bottom of the placement plate.

[0008] The working principle and beneficial effects of the present utility model:

[0009] Due to the self-locking function of the servo motor, the output shaft of the servo motor is in a self-locking state and remains stationary. The output shaft of the servo motor locks the rotating shaft through the driving gear and the driven gear, so that the rotating shaft remains stationary. Place the relay on the placement plate, and the drilling machine drills the relay. The debris generated by drilling falls onto the placement plate, and then the relay is removed.

[0010] At this time, start the servo motor. Through the driving gear and the driven gear, the rotating shaft and the placement plate rotate 180 degrees. The placement plate faces downward, and most of the debris automatically falls off. A small amount of smaller debris adheres to the placement plate. Start the cylinder and the blower. The blower supplies air towards the air outlet groove. The cylinder drives the scraper to move towards the placement plate. First, the scraper scrapes off the attached smaller debris. Then, the brush continues to clean the fine debris. Then, the air outlet groove blows air on the placement plate for further cleaning. After the cleaning is completed, the cylinder drives the scraper to retract into the placement groove. Then, the servo motor makes the rotating shaft and the placement plate rotate 180 degrees in the reverse direction, and the placement plate returns to its original position to continue drilling.

[0011] Based on the existing technology, this solution adds a scraper, a brush, and air blowing through the air outlet groove for cleaning, which can effectively remove the fine debris on the placement plate, thus ensuring the normal progress of the relay drilling work.

[0012] Optimally, the bracket is detachably connected with a collection groove located below the placement plate. The collection groove collects the debris falling from the placement plate.

[0013] Optimally, the placement groove is also fixedly provided with a scraping block facing the brush. When the brush retracts into the placement groove, the scraping block combs the bristles of the brush, thereby cleaning the debris attached to the bristles and improving the cleaning ability of the brush.

[0014] Optimally, the number of the scraping blocks is multiple, and the scraping blocks are triangular prisms. The triangular prism-shaped scraping blocks have a better combing effect on the bristles.

[0015] Optimally, the servo motors are symmetrically arranged along the axis of the bracket. By driving the rotation shaft to rotate with the symmetrically arranged servo motors, the rotation of the rotation shaft is made smoother, and the locking effect on the rotation shaft is better.

[0016] Optimally, the placement plate is provided with a positioning groove. The positioning groove is used to position the placement position of the relay, and can also limit and fix the relay. Description of the Drawings

[0019] Figure 3 is Figure 1 the structural schematic diagram of the scraper in Detailed Description of the Embodiment

[0020] The following is further detailed through specific embodiments:

[0021] The reference numerals in the accompanying drawings of the specification include: scraper 1, blower 2, cylinder 3, rotating shaft 4, placement plate 5, drilling machine 6, relay 7, servo motor 8, bracket 9, driven gear 10, driving gear 11, brush 12, air outlet groove 13, air outlet hole 14, connecting pipe 15.

[0022] In the following statements, orientation words such as "left", "right", "up", and "down" are based on the orientation shown in the drawings. In actual situations, if the corresponding structures change in the same direction based on the orientation and the relative positions remain unchanged, it does not affect the implementation of the solution.

[0023] Embodiment: A relay drilling device, as Figure 1 shown, includes a bracket 9 and a drilling machine 6. The top of the bracket 9 is rotatably connected to a rotating shaft 4. The rotating shaft 4 is coaxially and fixedly sleeved with a placement plate 5 located directly below the drilling machine 6. The bracket 9 is also fixedly provided with a servo motor 8. In this embodiment, the servo motor 8 is a servo motor 8MZ751A200 produced by Nidec Corporation. This type of servo motor 8 is equipped with an electromagnetic brake, and the braking force is much greater than the sum of the weights of the rotating shaft 4, the placement plate 5, and the relay 7.

[0024] The servo motor 8 drives a driving gear 11. The rotating shaft 4 is fixedly sleeved with a driven gear 10 meshing with the driving gear 11. The bracket 9 is provided with a placement groove. The placement groove is fixedly provided with a cylinder 3. The cylinder 3 drives a scraper 1 located in the placement groove, as Figure 3As shown, the scraping plate 1 is provided with a groove, in which a brush 12 and an air outlet groove 13 are fixedly arranged. The scraping plate 1 is fixedly provided with a blower 2 for supplying air to the air outlet groove 13. A connecting pipe 15 is fixedly connected between the blower 2 and the air outlet groove 13. The air outlet groove 13 is provided with a plurality of air outlet holes 14. The top of the scraping plate 1 and the top of the brush 12 are on the same horizontal plane as the bottom of the placement plate 5.

[0025] Since the servo motor 8 has a self-locking function, the output shaft of the servo motor 8 is in a self-locked and stationary state under the action of the electromagnetic brake. The output shaft of the servo motor 8 locks the rotating shaft 4 through the driving gear 11 and the driven gear 10, so that the rotating shaft 4 remains stationary. Place the relay 7 on the placement plate 5, and the drilling machine 6 drills the relay. The debris generated by drilling falls on the placement plate 5, and then the relay 7 is removed.

[0026] As Figure 2 shown, at this time, start the servo motor 8. Through the driving gear 11 and the driven gear 10, the rotating shaft 4 and the placement plate 5 are rotated 180 degrees. The placement plate 5 faces downward, and most of the debris automatically falls off. A small part of the smaller debris adheres to the placement plate 5. Start the cylinder 3 and the blower 2. The blower 2 supplies air to the air outlet groove 13, and the air outlet holes 14 blow air. The cylinder 3 drives the scraping plate 1 to move towards the placement plate 5. First, the scraping plate 1 scrapes off the attached smaller debris, and then the brush 12 continues to clean the fine debris. Then, the air outlet holes 14 blow air on the placement plate 5 for further cleaning. After the cleaning is completed, the cylinder 3 drives the scraping plate 1 to retract into the placement groove. Then, the servo motor 8 rotates the rotating shaft 4 and the placement plate 5 in the reverse direction by 180 degrees, and the placement plate 5 is reset to continue drilling the next relay 7.

[0027] Based on the existing technology, this solution adds cleaning by the scraping plate 1, the brush 12, and blowing air through the air outlet holes 14, which can effectively remove the fine debris on the placement plate 5, thus ensuring the normal progress of the drilling work of the relay 7.

[0028] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts, and equipment all adopt conventional models in the existing technology. In addition, the circuit connection adopts the conventional connection method in the existing technology, which will not be elaborated here.
