Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7 This utility model provides a drilling device for machining end caps of multi-stage hydraulic cylinders, including a support body 1 and a ball screw slide module 2 mounted on the surface of the support body 1. A machining mechanism 3 is provided on the surface of the ball screw slide module 2. Two protective plates 4, made of transparent acrylic material, are symmetrically rotatably connected to the surface of the support body 1 via bearings. A chip-extracting plate 5 is fixedly connected to the surface of the support body 1, and several through holes are evenly distributed on the surface of the chip-extracting plate 5. A collecting cylinder 6 is located inside the support body 1, below the chip-extracting plate 5. A railing 7 is rotatably connected to the support position of the support body 1. When drilling is required on the end cap, water is first poured into the collecting cylinder 6 to a certain height, and then the collecting cylinder 6 is pushed forward. The drill bit moves to the inside of the support body 1 until it is aligned with the chip-extracting plate 5. When drilling is required, the end cap is placed on the surface of the chip-extracting plate 5, and then force is applied to the protective plate 4 so that the two protective plates 4 rotate on the surface of the support body 1 through the hinge until the two protective plates 4 are aligned with the same axis. Then, the processing mechanism 3 is started to move the drill bit to the position where drilling is required. Then, the ball screw slide module 2 is started to move the drill bit toward the end cap and drill a hole in the end cap. The flying chips generated by drilling will be blocked by the protective plate 4. Due to the material of the protective plate 4, the processing progress of the end cap can be clearly observed. Some chips will fall into the inside of the collection cylinder 6 through the chip-extracting plate 5. The water inside the collection cylinder 6 will cool the chips and facilitate collection.

[0025] It should be noted that the ball screw slide module 2 consists of a ball screw, guide rail, slider, motor, coupling, support structure, sensor, lubrication and dustproof components, and fasteners, etc., which are existing technologies. Those skilled in the art can set them according to actual needs, and they will not be described in detail here.

[0026] It should be noted that the processing mechanism 3 consists of a turntable, a first forward and reverse motor, gear one, gear two, a moving groove, a moving block, a second forward and reverse motor, a lead screw, and a drill, etc. For reference, the drilling mechanism in Chinese Patent No. CN217453064U can be found.

[0027] In this embodiment, a through groove is provided at the center of the surface of the chip-stripping plate 5. The chip-stripping plate 5 has a square pyramidal structure and is concave on top and convex on the bottom. After the end cap is finished and picked up, the chips can be manually swept toward the chip-stripping plate 5. The through groove can quickly discharge a large amount of chips and larger chips. The concave shape of the chip-stripping plate 5 can not only make the chips gather toward the chip-stripping plate 5, but also quickly position the end cap, making it convenient to clamp the end cap.

[0028] In this embodiment, a guide bucket 8 is fixedly connected to the inside of the support body 1 by bolts. The guide bucket 8 and the chip removal plate 5 are on the same axis. A fan 9 is installed inside the support body 1. A duct is installed at the output end of the fan 9. The end of the duct away from the fan 9 is inserted into the inside of the guide bucket 8 and the duct is inclined downward. When the end cap is drilled, the fan 9 is started. The fan 9 blows air into the inside of the guide bucket 8. The air pressure causes a certain suction force to be generated on the surface of the chip removal plate 5, so that some smaller debris will enter the inside of the guide bucket 8 due to the suction force. The guide bucket 8 can guide the debris into the inside of the collection cylinder 6.

[0029] It should be noted that the fan 9 is existing technology, and those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0030] In this embodiment, a separating cylinder 10 is slidably connected inside the collecting cylinder 6. Several separating holes are evenly opened on the surface of the separating cylinder 10. A toothed plate 13 is fixedly connected to the surface of the separating cylinder 10, and a gear 12 is meshed with the surface of the toothed plate 13. A handwheel 11 is rotatably connected to the surface of the collecting cylinder 6. The shaft of the handwheel 11 passes through the surface of the collecting cylinder 6 and is fixedly connected to the gear 12. The debris entering the collecting cylinder 6 will be separated by the separating cylinder 10. When it is necessary to clean the debris inside the collecting cylinder 6, the railing 7 is rotated 90 degrees on the surface of the support body 1, and then the collecting cylinder 6 is pulled out from the inside of the support body 1. Then, the handwheel 11 is rotated, and the gear 12 connected to the handwheel 11 will rotate and drive the separating cylinder 10 to move upward through the toothed plate 13, making it convenient for workers to lift the separating cylinder 10. When the separating cylinder 10 is lifted, water will flow out from the inside of the separating cylinder 10 through the separating holes, while the debris will remain inside the separating cylinder 10, making it convenient to collect the debris separately. The water inside the collecting cylinder 6 can flow out through the faucet installed on the surface of the collecting cylinder 6.

[0031] In this embodiment, two symmetrical grooves 18 are opened on the upper surface of the support body 1. Each groove 18 is provided with a positioning plate 17. The adjacent sides of the two positioning plates 17 are fixedly connected to clamping plates 19. The end of the positioning plate 17 away from the clamping plates 19 is fixedly connected to a connecting plate 16. A stepper motor 14 is installed on the bottom surface of the support body 1. The output shaft of the stepper motor 14 is fixedly connected to a bidirectional screw 15. The bidirectional screw 15 passes through the two connecting plates 16 and is threadedly connected to them. When it is necessary to clamp the end cap, the end cap is placed on the surface of the chip removal plate 5. Then the stepper motor 14 is started, so that the bidirectional screw 15 rotates. The two connecting plates 16 threadedly connected to the bidirectional screw 15 will drive the positioning plate 17 to slide inside the groove 18, so that the two clamping plates 19 move closer to the end cap and clamp it. Then the stepper motor 14 is stopped. Since the two clamping plates 19 move synchronously, the end cap is centered and positioned. The adjacent sides of the two clamping plates 19 are V-shaped grooves, which facilitates clamping end caps of different sizes within a certain range.

[0032] It should be noted that the stepper motor 14 is existing technology, and those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0033] The use of this utility model involves the following steps:

[0034] S1: When drilling is required on the end cap, first pour water into the collection cylinder 6 to a certain height, then push the collection cylinder 6 into the support body 1 until it is on the same axis as the chip removal plate 5. When drilling is required, place the end cap on the surface of the chip removal plate 5, and then apply force to the protective plate 4 so that the two protective plates 4 rotate on the surface of the support body 1 through the hinge until the two protective plates 4 are on the same axis. Then start the processing mechanism 3 to move the drill bit to the position where drilling is required, and then start the ball screw slide module 2 to move the drill bit towards the end cap. Drill the end cap with the drill bit. The flying chips generated by drilling will be blocked by the protective plate 4. Due to the material of the protective plate 4, the processing progress of the end cap can be clearly observed. Some chips will fall into the collection cylinder 6 through the chip removal plate 5. The water inside the collection cylinder 6 will cool the chips and facilitate collection.

[0035] S2: When it is necessary to clamp the end cap, place the end cap on the surface of the chip removal plate 5, and then start the stepper motor 14 to make the bidirectional screw 15 rotate. The two connecting plates 16 that are threaded to the bidirectional screw 15 will drive the positioning plate 17 to slide inside the slide groove 18, so that the two clamping plates 19 move closer to the end cap and clamp it. Then stop the stepper motor 14. Since the two clamping plates 19 move synchronously, the end cap is centered and positioned. The adjacent side of the two clamping plates 19 is a V-shaped groove, which is convenient for clamping end caps of different sizes within a certain range.

[0036] S3: While drilling holes in the end cap, start the fan 9. The fan 9 will blow air into the guide bucket 8. The air pressure will cause the surface of the chip filter plate 5 to generate a certain suction force, so that some smaller chips will enter the interior of the guide bucket 8 due to the suction force. The guide bucket 8 can guide the chips into the interior of the collection cylinder 6.

[0037] S4: After the end cap is finished and picked up, the debris can be manually swept toward the chip removal plate 5. The through groove can quickly discharge a large amount of debris and larger debris. The concave shape of the chip removal plate 5 can not only gather the debris toward the chip removal plate 5, but also quickly position the end cap, making it convenient to clamp the end cap.

[0038] S5: The debris entering the collection cylinder 6 will be separated by the separator cylinder 10. When it is necessary to clean the debris inside the collection cylinder 6, rotate the railing 7 ninety degrees on the surface of the support body 1, and then pull the collection cylinder 6 out from the inside of the support body 1. Then, turn the handwheel 11. The gear 12 connected to the handwheel 11 will rotate and drive the separator cylinder 10 upward through the tooth plate 13, making it convenient for the worker to lift the separator cylinder 10. When the separator cylinder 10 is lifted, water will flow out from the inside of the separator cylinder 10 through the separation hole, while the debris will remain inside the separator cylinder 10, making it convenient to collect the debris separately. The water inside the collection cylinder 6 can flow out through the faucet installed on the surface of the collection cylinder 6.

[0039] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
