Technical Field

[0001] This utility model relates to the field of needle valve processing technology, and in particular to a vibratory drilling equipment for processing diesel engine needle valves. Background Technology

[0002] The needle valve of a diesel engine is a core component of the fuel injection system. The needle valve and the needle valve body usually form a needle valve assembly. The function of the needle valve is to control the injection timing, injection quantity and injection rate of the fuel injector. Its working process is closely related to the fuel injection system of the diesel engine. In the process of needle valve manufacturing, drilling equipment is required to drill holes in the needle valve.

[0003] When machining needle valves using drilling equipment, a large amount of metal chips are generated during the drilling process. Therefore, cutting fluid is required during drilling. However, the cutting fluid mixed with metal chips splashes around during drilling, making it inconvenient to collect and clean. Therefore, this application proposes a vibratory drilling equipment for machining diesel engine needle valves. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art that cutting fluid and debris are difficult to collect during the drilling of needle valves, and to propose a vibratory drilling device for the machining of diesel engine needle valves.

A nut is threaded onto the outer wall of the bidirectional lead screw. A connecting rod is fixed to one side of the nut. The connecting rod is fixed to one side of the clamp. Two sets of nuts and connecting rods are provided and are symmetrically distributed on the outer wall of the bidirectional lead screw.

[0007] Optionally, a sleeve frame is fixed to the top of the processing table. The sleeve frame is disposed on the outer wall of the bidirectional lead screw. One end of the bidirectional lead screw is rotatably connected to the inner wall of the sleeve frame. A sliding groove is provided on one side of the sleeve frame, and the connecting rod is slidably disposed on the inner wall of the sliding groove.

[0008] Optionally, the fixing component includes a ring fixed to the top end of one side of the clip, a pull rod slidably connected to the top end of the ring, a fixing plate fixed to the bottom end of the pull rod, the fixing plate being disposed on one side of the collection box, a spring fixed to the top end of the fixing plate, and the top end of the spring fixed to the bottom end of the ring.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 - Figure 5 As shown, the vibratory drilling equipment for machining diesel engine needle valves proposed in this utility model includes a machining table 1. A guide plate 2 is fixedly connected to the top of the machining table 1. A sliding sleeve 3 is slidably connected to one side of the guide plate 2. The sliding sleeve 3 is connected to the inside of the guide plate 2 through a hydraulic rod. A drilling machine 4 is fixedly connected to one side of the sliding sleeve 3. A clamping sleeve 5 is provided at the top of the machining table 1. A fitting groove 7 is provided on one side of the clamping sleeve 5. A needle valve body 6 is provided between two sets of clamping sleeves 5. The fitting groove 7 fits against the outer wall of the needle valve body 6. A driving assembly for driving the clamping sleeve 5 to move is provided at the top of the machining table 1. The driving assembly includes a motor 11. The motor 11 is fixedly connected to the top of the machining table 1. A bidirectional lead screw 12 is fixedly connected to the output end of the motor 11. A nut 13 is threadedly connected to the outer wall of the bidirectional lead screw 12. A connecting rod 14 is fixedly connected to one side of the sleeve 5. The connecting rod 14 is fixedly connected to one side of the sleeve 5. Two sets of nuts 13 and connecting rods 14 are provided and are symmetrically distributed on the outer wall of the bidirectional lead screw 12. A sleeve frame 15 is fixedly connected to the top of the processing table 1. The sleeve frame 15 is set on the outer wall of the bidirectional lead screw 12. One end of the bidirectional lead screw 12 is rotatably connected to the inner wall of the sleeve frame 15. A sliding groove is opened on one side of the sleeve frame 15. The connecting rod 14 is slidably set on the inner wall of the sliding groove. A collection groove 8 is opened on the inner wall of the sleeve 5. A support plate 9 is fixedly connected to the inner wall of the collection groove 8. A collection box 10 is installed on the top of the support plate 9. The collection box 10 is inserted into the inside of the sleeve 5. Multiple sets of filter holes are opened at the bottom of the collection box 10. A sealing gasket 20 is fixedly connected to the edge of one side of the sleeve 5. The sealing gasket 20 is made of rubber.

[0023] To address the issue of difficult collection of cutting fluid and chips during needle valve drilling, the needle valve body 6 can be placed between two sets of clamping sleeves 5 when machining the needle valve. Then, by starting the motor 11, the bidirectional lead screw 12 is rotated. As the lead screw 12 rotates, it causes the two sets of nuts 13 on the outer wall to move simultaneously towards the center. The movement of the nuts 13 simultaneously causes the connecting rod 14 to slide within a groove. The groove limits the movement trajectory of the connecting rod 14, and the sleeve 15 protects the connection between the nuts 13 and the bidirectional lead screw 12. As the two sets of connecting rods 14 and nuts 13 move towards the center, they also cause the two sets of clamping sleeves 5 to move towards the center until the fitting groove 7 on one side of the two sets of clamping sleeves 5 clamps the needle valve body 6. By setting a sealing gasket 20 on one edge of the jacket 5, the cutting fluid can be prevented from flowing out from the gap at the connection of the two sets of jackets 5 when they are in contact with each other. Then, the hydraulic rod in the guide plate 2 pushes the sliding sleeve 3 and the drilling machine 4 to move downward. The drilling machine 4 can then perform drilling on the needle valve body 6. During the drilling process, the metal chips and cutting fluid generated will splash in the collection tank 8 of the jacket 5, which can prevent the metal chips and cutting fluid from splashing to the surroundings. After entering the collection tank 8, the metal chips and cutting fluid can fall into the collection box 10. The metal chips can be blocked in the collection box 10 through the filter hole set at the bottom of the collection box 10, and the cutting fluid can flow into the bottom of the collection tank 8. This allows the metal chips and cutting fluid to be collected separately, which is convenient for subsequent classification and processing.

[0024] It should be noted that, as Figure 3 The top of the sleeve 5 is provided with a fixing component for fixing the position of the collection box 10. The fixing component includes a ring 16, which is fixedly connected to the top of one side of the sleeve 5. A pull rod 17 is slidably connected to the top of the ring 16. A fixing plate 18 is fixedly connected to the bottom of the pull rod 17. The fixing plate 18 is located on one side of the collection box 10. A spring 19 is fixedly connected to the top of the fixing plate 18. The top of the spring 19 is fixedly connected to the bottom of the ring 16. A handle 21 is fixedly connected to one side of the collection box 10. The handle 21 is arc-shaped.

[0025] When it is necessary to remove the metal debris from the collection box 10, the lever 17 can be pulled upwards, thereby moving the bottom fixing plate 18 upwards as well. When the fixing plate 18 moves, it will compress the spring 19 until the fixing plate 18 is removed from one side of the collection box 10, thus releasing the fixing of the collection box 10. Then, the collection box 10 can be pulled out from the collection slot 8, and the metal debris collected in the collection box 10 can be removed and cleaned by pulling the handle 21.

[0026] Furthermore, such as Figure 1 and Figure 4A connecting pipe 22 is fixedly connected to the bottom of one side of the jacket 5. A first valve 23 is fixedly connected to the outer wall of the connecting pipe 22. A storage box 24 is fixedly connected to one side of the processing table 1. The bottom of the connecting pipe 22 extends into the storage box 24. A water outlet pipe 25 is fixedly connected to one side of the storage box 24. A second valve is provided on the outer wall of the water outlet pipe 25. A telescopic pipe 26 is fixedly connected to the center of the connecting pipe 22. The telescopic pipe 26 is made of plastic.

[0027] When it is necessary to remove the cutting fluid from the collection tank 8, the first valve 23 can be opened to allow the cutting fluid collected at the bottom of the collection tank 8 to be transferred downward through the connecting pipe 22 until the cutting fluid flows into the storage tank 24, so that the cutting fluid can be collected in a concentrated manner. By opening the second valve, the outlet pipe 25 can be opened to allow the cutting fluid in the storage tank 24 to flow out through the outlet pipe 25. By setting a telescopic pipe 26 at the center of the connecting pipe 22, the internal communication of the connecting pipe 22 can be maintained when the position of the jacket 5 moves.

[0028] Working Principle: To address the issue of difficult collection of cutting fluid and chips during needle valve drilling, the needle valve body 6 is placed between two sets of clamping sleeves 5. Then, the motor 11 is started to rotate the bidirectional lead screw 12. As the lead screw 12 rotates, it causes the two sets of nuts 13 on the outer wall to move towards the center simultaneously. This movement of the nuts 13 also causes the connecting rod 14 to slide within a groove. The groove limits the movement trajectory of the connecting rod 14, and the sleeve 15 protects the connection between the nuts 13 and the bidirectional lead screw 12. As the two sets of connecting rods 14 and nuts 13 move towards the center, they also cause the two sets of clamping sleeves 5 to move towards the center until the fitting groove 7 on one side of the two sets of clamping sleeves 5 engages the needle valve body 6. The clamping mechanism, by setting a sealing gasket 20 on one edge of the clamping sleeve 5, prevents the cutting fluid from flowing out from the gap at the connection between the two sets of clamping sleeves 5 when they are in contact with each other. Then, the hydraulic rod in the guide plate 2 pushes the sliding sleeve 3 and the drilling machine 4 to move downwards, and the drilling machine 4 can perform drilling on the needle valve body 6. During the drilling process, the metal chips and cutting fluid generated will splash in the collection tank 8 of the clamping sleeve 5, which can prevent the metal chips and cutting fluid from splashing to the surroundings. After entering the collection tank 8, the metal chips and cutting fluid can fall into the collection box 10. The metal chips can be blocked in the collection box 10 through the filter hole set at the bottom of the collection box 10, and the cutting fluid can flow into the bottom of the collection tank 8, so that the metal chips and cutting fluid can be collected separately, which is convenient for subsequent classification and processing.

[0029] When it is necessary to remove the metal debris from the collection box 10, the pull rod 17 can be pulled upward, thereby moving the bottom fixing plate 18 upward as well. When the fixing plate 18 moves, it will compress the spring 19 until the fixing plate 18 is removed from one side of the collection box 10, thus releasing the fixing of the collection box 10. Then, the collection box 10 can be pulled out from the collection tank 8, and the metal debris collected in the collection box 10 can be removed and cleaned by pulling the handle 21. When it is necessary to remove the cutting fluid from the collection tank 8, the first valve 23 can be opened, so that the cutting fluid collected at the bottom of the collection tank 8 can be transferred downward through the connecting pipe 22 until the cutting fluid flows into the storage tank 24, so that the cutting fluid can be collected in a concentrated manner. By opening the second valve, the outlet pipe 25 can be opened, so that the cutting fluid in the storage tank 24 can flow out through the outlet pipe 25. By setting the telescopic pipe 26 at the center of the connecting pipe 22, the internal communication of the connecting pipe 22 can be maintained when the position of the jacket 5 moves.

[0030] The above specific embodiments are merely several optional embodiments of this utility model.
