Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive parts processing equipment technology, and in particular to a threaded hole flushing device. Background Technology
[0002] Pins and shafts constitute a large proportion of automotive parts and are in high demand. The machining of pins and shafts usually involves the machining of threaded holes. After machining, the threaded holes often accumulate waste and oil, which can affect the use of the pins and shafts. Therefore, the threaded holes need to be flushed after machining. Currently, flushing is usually done manually, which is time-consuming and labor-intensive. Therefore, a new flushing device is needed to solve this problem. Summary of the Invention
[0003] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.
[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a threaded hole flushing device.
[0005] To achieve the above objectives, the technical solution of the present invention is: a threaded hole flushing device, comprising a frame and a flushing head, wherein a carrying tray is rotatably connected to the frame, the carrying tray has a plurality of placement slots, the frame is provided with a drive mechanism for intermittently rotating the carrying tray, each placement slot has a water inlet hole at its bottom, one of the water inlets being aligned with the flushing head, the frame is fixedly connected with a guide rail, the outlet of the guide rail is connected to one of the placement slots not aligned with the flushing head, the frame is provided with a push-out mechanism for pushing material from the guide rail into the placement slot, the inlet of the guide rail is provided with a feeding mechanism for allowing material to enter the guide rail, and the top of one of the placement slots is provided with a discharge mechanism for pushing material out of the placement slot.
[0006] By adopting the above technical solution, the feeding mechanism can continuously put the pins into the guide rail. As the pins are continuously put in, the initial pins put into the guide rail are pushed to the exit of the guide rail. Then, the ejection mechanism pushes the pins into the placement slot of the carrying tray. Next, the drive mechanism drives the carrying tray to rotate, so that the placement slot containing the pins moves above the flushing head. The flushing head flushes high-pressure water into the threaded hole of the pin through the water inlet, cleaning the waste and oil in the threaded hole. After flushing, the drive mechanism drives the carrying tray to rotate again, so that the pin moves to the discharge mechanism. Under the action of the discharge mechanism, the pin is removed from the flushing device, realizing automatic flushing of the pin thread, thereby reducing the use of manpower.
[0007] Preferably, the drive mechanism includes a toothed gear and an input gear. The input gear is driven by the loading disk, the toothed gear is rotatably connected to the frame, and the toothed gear and the input gear are driven by each other. This invention utilizes the intermittent meshing of the toothed gear with the input gear to achieve intermittent driving of the loading disk.
[0008] Preferably, the feeding mechanism includes a hopper, a conveyor belt, drive rollers, a motor, and a cylinder. The bottom of the hopper is an inclined surface, and the outlet of the hopper is connected to the inlet of the guide rail. The conveyor belt is disposed between the outlet of the hopper and the inlet of the guide rail. Two drive rollers are provided, and both drive rollers are rotatably connected to the frame. The conveyor belt is arranged around the two drive rollers. One of the drive rollers is drively connected to the output shaft of the motor. The surface of the conveyor belt is on the same horizontal plane as the bottom of the guide rail and the lowest point of the bottom of the hopper. The cylinder is fixedly connected to the frame. The output rod of the cylinder is perpendicular to the conveying direction of the conveyor belt and parallel to the guiding direction of the guide rail. The frame is provided with a control mechanism for controlling the operation of the cylinder. This invention utilizes the inclined surface at the bottom of the hopper, causing the pins placed on the hopper to slide out of the hopper outlet continuously under their own weight. The conveyor belt at the hopper outlet, driven by motor one and drive rollers, continuously moves around the two drive rollers. When a pin falls onto the conveyor belt, it is transported to the guide rail by the conveyor belt. Since the conveyor belt is perpendicular to the guide rail, the pin will press against the side wall of the guide rail after leaving the conveyor belt. When the ejection mechanism pushes a pin on the guide rail into the placement slot, a gap is created on the guide rail. Cylinder one will push all the pins on the guide rail to slide along the guide rail to fill the gap. After cylinder one completes its action, the gap will move to the outlet of the conveyor belt. At this time, the next pin will be placed into the gap of the guide rail by the conveyor belt. This process is repeated to achieve continuous feeding of pins.
[0009] Preferably, the hopper is equipped with a discharge aid device to assist material discharge. The discharge aid device includes two rollers, which are respectively disposed on both sides of the hopper and rotatably connected to it. The two rollers are interconnected via a belt, and one of the rollers is connected to a motor. In this invention, the two rollers rotate in opposite directions under the drive of the motor and the belt. When the pin presses against the roller, it is pulled towards the opening of the hopper by the frictional force. This prevents the pins from blocking the outlet due to mutual compression.
[0010] Preferably, the ejection mechanism includes a second cylinder, which is fixedly connected to the frame. The output rod of the second cylinder is aligned with the outlet of the guide rail, and the frame is equipped with a control mechanism for controlling the operation of the second cylinder. This invention utilizes the linear motion of the output rod of the second cylinder to push the pin into the placement slot.
[0011] Preferably, the control device includes a reversing valve, a rack, an elastic element, and a pressing rod. The reversing valve is connected to either cylinder one or cylinder two. The rack and the pressing rod are slidably connected to the frame. The rack is driven by the toothed gear and the pressing rod. The pressing rod abuts against the trigger button of the reversing valve. The elastic element is disposed between the pressing rod and the frame. This invention utilizes a reversing valve to change the inlet and outlet ends of cylinder one or cylinder two, thereby controlling cylinder one and cylinder two. The reversing valve is mechanical; pressing the trigger button on the reversing valve changes the position of the valve core. Releasing the trigger button resets the valve core. Utilizing this property of the reversing valve, through the transmission connection between the rack and the toothed gear, when the teeth on the toothed gear connect with the rack, the rack, driven by the toothed gear, pushes the pressing rod in a direction that overcomes the elastic force of the elastic element. Pressing the trigger button of the reversing valve causes the output rod of cylinder one or cylinder two to extend and push the pin. When the toothed gear is not connected to the rack, the elastic element releases its elastic force, pushing the rack to reset. At this time, the valve core of the reversing valve resets, and the output rod of cylinder one or cylinder two retracts.
[0012] Preferably, the pressing rod is connected to the rack and pinion via a push rod and an elastic element two. The push rod is fixedly connected to the rack and slidably connected to the frame. The elastic element two is disposed between the push rod and the pressing rod, and the maximum elastic force of the elastic element one is less than the minimum elastic force of the elastic element two. In this invention, the minimum elastic force of the elastic element two is greater than the maximum elastic force of the elastic element one. Therefore, when the rack pushes the push rod to slide, the push rod will first push the pressing rod to slide via the elastic element two, causing the elastic element one to be compressed. When the elastic element one is fully compressed, the pressing rod presses the trigger button of the reversing valve to its limit position. At this time, the push rod continues to squeeze the elastic element two under the drive of the rack, causing the elastic element two to be compressed and deformed. During this process, the pressing rod will always remain pressed against the trigger button of the reversing valve. In this way, the duration for which the pressing rod presses the trigger button of the reversing valve is guaranteed, ensuring that cylinder one and cylinder two have enough time to complete the action.
[0013] Preferably, the discharge mechanism includes a push plate, which is inclined and suspended above the loading tray, and is fixedly connected to the frame. This invention utilizes the inclined push plate so that when the loading tray drives the pin to press against the push plate, a continuously decreasing angle is formed between the push plate and the side wall of the placement groove, thereby continuously squeezing out the pin.
[0014] Preferably, the flushing head is connected to a water inlet pipe, which is equipped with a valve for connecting or disconnecting the water flow. The bottom of the carrying tray has several pressing blocks, the number of which is the same as the number of placement slots. Each pressing block abuts against the trigger button of the valve. This invention utilizes the pressing blocks to press the trigger button of the valve, causing the valve to open. At this time, water can flow from the flushing head through the valve. When the carrying tray rotates, the pressing blocks separate from the trigger button, causing the valve to close and the flushing head to stop discharging water. When the carrying tray stops rotating again, another pressing block presses against the trigger button of the valve, causing the valve to open again. This method ensures that the flushing head only sprays water when a pin is present at the top, avoiding water waste.
[0015] Preferably, the frame is surrounded by baffles to restrict the flow of wastewater around the platform, and the frame has a drainage trough connected to a drain pipe. This invention utilizes a baffle to prevent wastewater from flowing freely through the threaded holes, guiding it into the drainage trough under the guidance of the baffles, and then discharging it from the rinsing device through the drain pipe at the bottom of the trough.
[0016] In summary, the beneficial effects of this invention are:
[0017] 1. By using the intermittent drive mechanism to drive the stage, in conjunction with the ejection mechanism, feeding mechanism and discharge mechanism, the threaded hole of the pin is automatically flushed, reducing the use of manpower and improving processing efficiency.
[0018] 2. By using a valve and a pressing block, the pressing block will separate from the valve trigger button during the rotation of the tray, causing the flushing head to stop discharging water, thus saving water.
[0019] 3. Both the loading tray and the control device are driven by a toothed gear in the drive mechanism, so that the rotation of the loading tray and the actions of cylinder one and cylinder two can be carried out in a certain sequence without interfering with each other.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0036] like Figure 1As shown, a threaded hole flushing device includes a frame 1 and a flushing head 2. The frame 1 is rotatably connected to a carrying tray 3, which has several placement slots 4. The frame 1 is equipped with a drive mechanism for intermittently rotating the carrying tray 3. Each placement slot 4 has a water inlet 5 at its bottom, one of which is aligned with the flushing head 2. The frame 1 is fixedly connected to a guide rail 6, the outlet of which is connected to one of the placement slots 4 that is not aligned with the flushing head 2. The frame 1 is equipped with a push-out mechanism for pushing materials from the guide rail 6 into the placement slot 4. The inlet of the guide rail 6 is equipped with a feeding mechanism for allowing materials to enter the guide rail 6. Above one of the placement slots 4 is a discharge mechanism for pushing materials out of the placement slot 4.
[0037] By adopting the above technical solution, the feeding mechanism can continuously put the pins into the guide rail 6. As the pins are continuously put in, the initial pins put into the guide rail 6 will be pushed to the outlet of the guide rail 6. Then, the ejection mechanism will push the pins into the placement slot 4 of the carrying tray 3. Next, the drive mechanism will drive the carrying tray 3 to rotate, so that the placement slot 4 carrying the pins will move above the flushing head 2. The flushing head 2 will flush the threaded hole of the pin with high pressure water through the water inlet 5, and clean the waste and oil in the threaded hole. After the flushing is completed, the drive mechanism will drive the carrying tray 3 to rotate again, so that the pins will move to the discharge mechanism. The pins will be removed from the flushing device under the action of the discharge mechanism, realizing automatic flushing of the pin threaded hole, thereby reducing the use of manpower.
[0038] like Figure 2 As shown, the drive mechanism includes a toothed gear 7 and an input gear 8. The input gear 8 is connected to the loading plate 3, and the toothed gear 7 is rotatably connected to the frame 1. The toothed gear 7 and the input gear 8 are mutually connected. By intermittently meshing the toothed gear 7 with the input gear 8, the intermittent drive of the loading plate 3 is achieved.
[0039] like Figure 1 and Figure 3As shown, the feeding mechanism includes a hopper 9, a conveyor belt 10, a drive roller 11, a motor 12, and a cylinder 13. The bottom of the hopper 9 is an inclined surface, and the outlet of the hopper 9 is connected to the inlet of the guide rail 6. The conveyor belt 10 is located between the outlet of the hopper 9 and the inlet of the guide rail 6. There are two drive rollers 11, and both drive rollers 11 are rotatably connected to the frame 1. The conveyor belt 10 is arranged around the two drive rollers 11. One of the drive rollers 11 is connected to the output shaft of the motor 12. The surface of the conveyor belt 10 is on the same horizontal plane as the bottom of the guide rail 6 and the lowest point of the bottom of the hopper 9. The cylinder 13 is fixedly connected to the frame 1. The output rod of the cylinder 13 is perpendicular to the conveying direction of the conveyor belt 10 and parallel to the guiding direction of the guide rail 6. The frame 1 is provided with a control mechanism for controlling the operation of the cylinder 13. Using the inclined surface at the bottom of the hopper 9, the pins placed on the hopper 9 will continuously slide out of the outlet of the hopper 9 under their own weight. The conveyor belt 10 located at the outlet of the hopper 9 will continuously move around the two drive rollers 11 under the drive of the motor 12 and the drive roller 11. When the pin falls on the conveyor belt 10, it will be transported to the guide rail 6 under the action of the conveyor belt 10. Since the conveyor belt 10 is perpendicular to the guide rail 6, the pin will press against the side wall of the guide rail 6 after leaving the conveyor belt 10. When the ejection mechanism pushes a pin on the guide rail 6 into the placement slot 4, when a gap is created on the guide rail 6, the cylinder 13 will push all the pins on the guide rail 6 to slide along the guide rail 6 to fill the gap. After the cylinder 13 completes its action, the gap will be transferred to the outlet of the conveyor belt 10. At this time, the next pin will be placed into the gap of the guide rail 6 by the conveyor belt 10. This process is repeated to realize the continuous feeding of the pins.
[0040] like Figure 1 and Figure 3 As shown, the hopper 9 is equipped with a discharge aid device to assist material discharge. The discharge aid device includes two rollers 14, which are respectively located on both sides of the hopper 9. Both rollers 14 are rotatably connected to the hopper 9 and are interconnected by a belt 28. One of the rollers 14 is connected to a motor 29. The two rollers 14 rotate in opposite directions under the drive of the motor 29 and the belt 28. When the pin abuts against the roller 14, it is driven towards the opening of the hopper 9 by the frictional force. In this way, the pins do not block the outlet due to mutual compression.
[0041] like Figure 1 As shown, the ejection mechanism includes a second cylinder 15, which is fixedly connected to the frame 1. The output rod of the second cylinder 15 is aligned with the outlet of the guide rail 6. The frame 1 is equipped with a control mechanism for controlling the operation of the second cylinder 15. The linear motion of the output rod of the second cylinder 15 is used to push the pin into the placement slot 4.
[0042] like Figure 2 As shown, the control device includes a reversing valve, a rack 16, an elastic element 17, and a pressing rod 18. The reversing valve is connected to either cylinder 13 or cylinder 15. The rack 16 and the pressing rod 18 are slidably connected to the frame 1. The rack 16 is driven by the toothed gear 7. The rack 16 is also driven by the pressing rod 18. The pressing rod 18 abuts against the trigger button of the reversing valve. The elastic element 17 is disposed between the pressing rod 18 and the frame 1. By using a reversing valve to change the inlet and outlet of cylinder 13 or cylinder 2 15, control of cylinder 13 and cylinder 2 15 is achieved. The reversing valve is mechanical. By pressing the trigger button on the reversing valve, the position of the valve core is changed. After releasing the trigger button, the valve core resets. Utilizing this property of the reversing valve, through the transmission connection between rack 16 and toothed gear 7, when the teeth on toothed gear 7 are connected to rack 16, rack 16 will push the pressing rod 18 to slide in the direction of overcoming the elastic force of elastic element 17 under the drive of toothed gear 7. Pressing the trigger button of the reversing valve causes the output rod of cylinder 13 or cylinder 2 15 to extend and push the pin. When toothed gear 7 is not connected to rack 16, elastic element 17 releases its elastic force and pushes rack 16 reset. At this time, the valve core of the reversing valve resets, and the output rod of cylinder 13 or cylinder 2 15 also retracts.
[0043] like Figure 2-3 As shown, the pressing rod 18 is connected to the rack 16 via the push rod 19 and the second elastic element 20. The push rod 19 is fixedly connected to the rack 16 and slidably connected to the frame 1. The second elastic element 20 is disposed between the push rod 19 and the pressing rod 18. The maximum elastic force of the first elastic element 17 is less than the minimum elastic force of the second elastic element 20. The minimum elastic force of elastic element 20 is greater than the maximum elastic force of elastic element 17. Therefore, when rack 16 pushes push rod 19 to slide, push rod 19 will first push push rod 18 to slide through elastic element 20, causing elastic element 17 to be compressed. When elastic element 17 is fully compressed, push rod 18 will press the trigger button of the reversing valve to the limit position. At this time, push rod 19 continues to squeeze elastic element 20 under the action of rack 16, causing elastic element 20 to be compressed and deformed. During this process, push rod 18 will always remain pressed against the trigger button of the reversing valve. In this way, the duration of press rod 18 pressing the trigger button of the reversing valve is guaranteed, ensuring that cylinder 13 and cylinder 25 have enough time to complete the action.
[0044] like Figure 1 As shown, the discharge mechanism includes a push-out plate 21, which is inclined and suspended above the loading tray 3. The push-out plate 21 is fixedly connected to the frame 1. By using the inclined push-out plate 21, when the loading tray 3 drives the pin to press against the push-out plate 21, a continuously decreasing angle is formed between the push-out plate 21 and the side wall of the placement groove 4, thereby continuously squeezing out the pin.
[0045] like Figure 5 As shown, the flushing head 2 is connected to a water inlet pipe 22, which is equipped with a valve 24 for connecting or disconnecting the water flow. Several pressing blocks 23 are located at the bottom of the carrying tray 3, the number of which is the same as the number of placement slots 4. The pressing blocks 23 abut against the trigger button of the valve 24. By pressing the trigger button of the valve 24 with the pressing block 23, the valve 24 is opened, allowing water to spray from the flushing head 2. When the carrying tray 3 rotates, the pressing block 23 separates from the trigger button of the valve 24, closing the valve 24 and stopping the water flow from the flushing head 2. When the carrying tray 3 stops rotating again, another pressing block presses against the trigger button of the valve 24, reopening the valve 24. This method ensures that the flushing head 2 only sprays water when a pin is present at the top, avoiding water waste.
[0046] like Figure 1 As shown, the frame 1 is surrounded by baffles 25 to restrict the flow of wastewater. The frame 1 has a drainage trough 26, which is connected to a drain pipe 27. The baffles prevent the wastewater from flowing around the threaded holes from flowing around, and instead guide it into the drainage trough 26 under the guidance of the baffles 25, and discharge it from the rinsing device through the drain pipe 27 at the bottom of the drainage trough 26.
[0047] It should be noted that many specific details have been set forth in the above description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
