Description

Technical Field

[0001] The utility model relates to the field of valve spring seat processing, and particularly relates to a valve spring seat screening device. Background Technique

[0002] The valve spring is a small tool that ensures the valve seats in time and fits tightly, preventing the valve from jumping during engine vibration and destroying its sealing performance. The valve spring seat, as a component product made by welding multi-ring circular shafts with different diameters on a circular plate, can play a role in fixedly connecting the valve spring; during the production process of the valve spring seat, due to various production processes, the produced valve spring seats often have different diameters, and it is often necessary to screen them after product production, so a screening device is required.

[0003] In the existing valve spring seat screening device, a large number of valve spring seats are placed in the screening tray, then screening openings with different sizes are opened, and the screening tray is vibrated by a vibration motor, so that the valve spring seats move and pass through the screening openings with different sizes to achieve the screening purpose. However, since a large number of valve spring seats enter the device simultaneously and the valve spring seats are stacked on each other, some valve spring seats are difficult to enter the corresponding screening openings and be screened, thus reducing the screening efficiency of the valve spring seats and the feeding efficiency of the valve spring seats. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a valve spring seat screening device to solve the technical problem that valve spring seats stack on each other in the screening tray, making it difficult for some valve spring seats to enter the corresponding screening openings, thereby reducing the screening efficiency of the valve spring seats.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A valve spring seat screening device, including a box body, the interior of the box body is respectively provided with a top plate and an inclined plate, and the top of the inclined plate is respectively penetrated by a first material dropping port, a second material dropping port and a third material dropping port, and a vibration motor is installed at the bottom of the inclined plate. The top of the box body is installed with a material cylinder through a fixing frame. One side of the box body is respectively provided with a feeding port and a guide plate, and an electric push rod is installed on one side of the guide plate. The output end of the electric push rod is installed with a push plate through a piston rod.

[0006] By adopting the above technical solution, when feeding is required, the electric push rod can be started to make the piston rod extend, thereby driving the push plate to move, and the push plate can push the lowermost valve spring seat to move so that the valve spring seat can be pushed into the box body.

[0007] Further, three baffle plates are provided at the top of the guide plate, and the bottom of the material cylinder is located between the baffle plates.

[0008] By adopting the above technical solution, the setting of the baffle can prevent the valve spring seat from sliding out of the guide plate, enabling the valve spring seat to smoothly enter the interior of the box body.

[0009] Further, three first collection boxes are slidably connected to the lower part inside the box body, and a handle is installed on the outer surface of the first collection box.

[0010] By adopting the above technical solution, the user can pull the first collection box through the handle, so that the first collection box is moved out of the box body, thereby facilitating the cleaning of the valve spring seat inside the first collection box.

[0011] Further, the three first collection boxes are respectively located directly below the first material dropping port, the second material dropping port, and the third material dropping port.

[0012] By adopting the above technical solution, the first collection box can collect the valve spring seats that fall downward through the first material dropping port, the second material dropping port, and the third material dropping port.

[0013] Further, a discharge port is opened on the other side of the box body, and one side of the inclined plate slopes downward along the direction of the discharge port.

[0014] By adopting the above technical solution, so that the valve spring seat can slide on the inclined plate, facilitating the screening of the valve spring seat.

[0015] Further, a second collection box is also slidably connected to the other side of the box body, and the second collection box is located below the discharge port.

[0016] By adopting the above technical solution, so that the valve spring seats that are not screened can slide into the second collection box through the discharge port, thereby enabling the collection of the valve spring seats.

[0017] Further, a plurality of valve spring seats are placed inside the material cylinder, and the bottom of one valve spring seat contacts the top of the guide plate.

[0018] By adopting the above technical solution, so that the staff can put the valve spring seats into the material cylinder, facilitating the subsequent pushing of the valve spring seats into the box body.

[0019] Further, the distance between the inclined plate and the top plate is slightly larger than the thickness of the valve spring seat.

[0020] By adopting the above technical solution, the top plate can play a certain limiting role on the valve spring seat, preventing the valve spring seat from tilting up.

[0021] Further, the distance between the material cylinder and the guide plate is larger than the thickness of one valve spring seat.

[0022] By adopting the above technical solution, it is possible to push only one valve spring seat to move each time, preventing a large number of valve spring seats from being pushed simultaneously.

[0023] Furthermore, the bottom of the push plate contacts the top of the guide plate, and the push plate is located on one side of the valve spring seat.

[0024] By adopting the above technical solution, when the push plate moves, it can push the valve spring seat to move, so that the valve spring seat slides into the inside of the feed port through the guide plate.

[0025] In summary, the main beneficial effects of the present utility model are as follows:

[0026] The present utility model is provided with an inclined plate, an electric push rod, a push plate, a guide plate and a cylinder. When feeding is required, the valve spring seat can be placed inside the cylinder. At this time, the lowermost valve spring seat will contact the top of the guide plate. Then, the electric push rod can be started to make the piston rod extend, thereby driving the push plate to move. The push plate can then push the lowermost valve spring seat to move, so that the valve spring seat can be pushed onto the inclined plate inside the box. Then, the valve spring seat slides down and is screened by the first blanking port, the second blanking port or the third blanking port. By this method, the feeding effect can be improved, so that the valve spring seats can only enter the box one by one, preventing stacking between the valve spring seats, and thus improving the screening efficiency of the valve spring seats.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.

[0034] The embodiments of the present invention will be described below according to its overall structure.

[0035] Embodiment 1:

[0036] A valve spring seat screening device, as Figures 1-5 shown, includes a box body 1. The inner part of the box body 1 is respectively provided with a top plate 2 and an inclined plate 4. The top of the inclined plate 4 is respectively penetrated by a first blanking port 5, a second blanking port 6 and a third blanking port 7. The sizes of the first blanking port 5, the second blanking port 6 and the third blanking port 7 increase in sequence from left to right, which is convenient for screening the valve spring seat 21. And a vibration motor 8 is installed at the bottom of the inclined plate 4. A material cylinder 16 is installed at the top of the box body 1 through a fixing frame 17. One side of the box body 1 is respectively provided with a feeding port 20 and a guide plate 12. And an electric push rod 14 is installed on one side of the guide plate 12. The output end of the electric push rod 14 is installed with a push plate 15 through a piston rod. When feeding is required, the electric push rod 14 can be started to make the piston rod extend, and then drive the push plate 15 to move. The push plate 15 can push the lowermost valve spring seat 21 to move, so that the valve spring seat 21 can be pushed into the box body 1.

[0037] Specifically, a plurality of valve spring seats 21 are placed inside the material cylinder 16. The bottom of one valve spring seat 21 is in contact with the top of the guide plate 12, so that the staff can put the valve spring seat 21 into the material cylinder 16, which is convenient for subsequently pushing the valve spring seat 21 into the box body 1. The distance between the inclined plate 4 and the top plate 2 is slightly larger than the thickness of the valve spring seat 21. The top plate 2 can play a certain limiting role on the valve spring seat 21 to prevent the valve spring seat 21 from tilting. Three first collection boxes 9 are slidably connected to the lower part inside the box body 1. And a handle is installed on the outer surface of the first collection box 9. The user can pull the first collection box 9 through the handle to make the first collection box 9 move out of the box body 1, so as to facilitate cleaning the valve spring seat 21 inside the first collection box 9.

[0038] Refer to Figures 2-4, three first collection bins 9 are respectively located directly below the first discharge opening 5, the second discharge opening 6, and the third discharge opening 7. The first collection bin 9 can collect the valve spring seats 21 that fall downward through the first discharge opening 5, the second discharge opening 6, and the third discharge opening 7. The distance between the cartridge 16 and the guide plate 12 is greater than the thickness of one valve spring seat 21 and less than the sum of the thicknesses of two valve spring seats 21, so that only one valve spring seat 21 can be pushed to move each time, preventing a large number of valve spring seats 21 from being pushed simultaneously. The bottom of the push plate 15 contacts the top of the guide plate 12. The push plate 15 is located on one side of the valve spring seat 21. When the push plate 15 moves, it can push the valve spring seat 21 to move. One side of the guide plate 12 is inclined downward along the direction of the feed inlet 20, so that the valve spring seat 21 slides into the feed inlet 20 through the guide plate 12.

[0039] Refer to Figures 1-4 , a discharge opening 3 is provided on the other side of the box body 1. One side of the inclined plate 4 is inclined downward along the direction of the discharge opening 3, so that the valve spring seat 21 can slide on the inclined plate 4, facilitating the screening of the valve spring seat 21. A second collection bin 10 is also slidably connected to the other side of the box body 1. The second collection bin 10 is located below the discharge opening 3, so that the un-screened valve spring seats 21 can slide into the second collection bin 10 through the discharge opening 3, thereby collecting the valve spring seats 21. A support frame 11 is fixed to the lower part of one side of the box body 1. The top of the support frame 11 is connected to the bottom of the guide plate 12. The support frame 11 can support the guide plate 12 and improve the stability of the guide plate 12. Observation windows 18 and a control panel 19 are respectively provided on the outer surface of the box body 1, and the control panel 19 is electrically connected to the vibration motor 8 and the electric push rod 14 respectively, facilitating the staff to start or stop the vibration motor 8 and the electric push rod 14 through the control panel 19.

[0040] Embodiment 2:

[0041] On the basis of the above Embodiment 1, in order to prevent the valve spring seat 21 from sliding out from both sides of the guide plate 12, it is necessary to limit the valve spring seat 21. Therefore, the following structure is set.

[0042] Refer to Figures 1-3 , three baffles 13 are provided on the top of the guide plate 12. The bottom of the cartridge 16 is located between the baffles 13. The setting of the baffles 13 can prevent the valve spring seat 21 from sliding out of the guide plate 12, so that the valve spring seat 21 can smoothly enter the box body 1.

[0043] The working principle of the present utility model is as follows: First, the staff can place valve spring seats 21 with different diameters into the interior of the cartridge 16. At this time, the lowermost valve spring seat 21 will contact the top of the guide plate 12. Then, the electric push rod 14 can be activated to make the piston rod extend, thereby driving the push plate 15 to move. The push plate 15 can then push the lowermost valve spring seat 21 to move so that the valve spring seat 21 can be pushed onto the inclined plate in the box body 1. Then, the valve spring seat 21 slides downward, while the valve spring seat 21 above drops onto the push plate 15. The setting of the push plate 15 can prevent the valve spring seats 21 in the cartridge 16 from directly dropping onto the guide plate 12. After the lowermost valve spring seat 21 is pushed into the box body 1, the electric push rod 14 can work to make the piston rod contract, thereby driving the push plate 15 to reset. When the push plate 15 no longer contacts the valve spring seat 21, the valve spring seat 21 drops downward. At this time, the lowermost valve spring seat 21 contacts the guide plate 12 again, facilitating the next time to push the valve spring seat 21 into the interior of the box body 1 through the push plate 15, and facilitating the valve spring seat 21 to enter the interior of the box body 1 orderly;

[0044] After the valve spring seat 21 enters the inclined plate 4 in the box body 1, the vibration motor 8 can be activated to make the vibration motor 8 vibrate the inclined plate 4. At this time, the valve spring seat 21 will slide downward. When the diameter of the valve spring seat 21 is smaller than the width of the first discharge opening 5, the valve spring seat 21 will drop into the lower first collection box 9 through the first discharge opening 5. And when the diameter of the valve spring seat 21 is larger than the width of the first discharge opening 5 and smaller than the width of the second discharge opening 6, the valve spring seat 21 will drop into the lower first collection box 9 through the second discharge opening 6. If the diameter of the valve spring seat 21 is larger than the widths of the first discharge opening 5 and the second discharge opening 6 and smaller than the width of the third discharge opening 7, the valve spring seat 21 will drop into the lower first collection box 9 through the third discharge opening 7. In this way, the valve spring seat 21 can be screened by the first discharge opening 5 or the second discharge opening 6 or the third discharge opening 7, and the unscreened valve spring seats 21 will drop into the second collection box 10 through the discharge port 3.
