Description

Technical Field

[0001] The present invention relates to the technical field of valve tappet processing, and particularly relates to a valve tappet processing device and a processing method thereof. Background Art

[0002] During the processing of valve tappets, a quenching device is required to quench the valve tappet components. Since the valve tappet components are in a circular tube shape, quenching oil, oxides or other impurities are likely to adhere to the inside of the quenched valve tappet components. These impurities are not easily shaken off by the collision between multiple valve tappet components inside the valve tappet components, nor are they easy to clean. As the valve tappet components enter subsequent processing equipment, such as grinding equipment, it is easy to affect the grinding quality, thereby affecting the product quality and being inconvenient for use. Summary of the Invention

[0003] Based on the technical problem that it is not convenient to clean the inside of the quenched valve tappet components, the present invention proposes a valve tappet processing device and a processing method thereof.

[0004] A valve tappet processing device and a processing method thereof proposed by the present invention include a vibrating blanking machine and a base. A transfer mechanism is installed on the upper surface of the base. The transfer mechanism includes a material transport tray. A mounting plate is fixedly connected to the upper surface of the base. An installation groove is formed on the surface of the mounting plate. The axis of the installation groove is rotationally connected to the axis of the material transport tray through a rotating shaft. A driving motor is fixedly connected to the other surface of the mounting plate. The output shaft of the driving motor is in transmission connection with the rotating shaft on the surface of the material transport tray. It can also be controlled by an external chassis using the chip programming in the chassis to control the operation of the driving motor, so as to facilitate the accurate operation of the driving motor. A blanking mechanism is installed on the surface of the blanking pipe of the vibrating blanking machine. The blanking mechanism includes a discharge pipe. The discharge pipe is inclined, and a discharge groove is formed at the lower end of the discharge pipe.

[0005] Preferably, a material transport column is fixedly connected to the surface of the material transport tray. An adjustment column is fixedly inserted into the inner wall of the material transport column. The adjustment column is in a hollow shape with both ends sealed. An airbag is fixedly connected to one end of the material transport column. The airbag is located in the installation groove. The airbag includes a connecting airbag and a squeezing airbag. The connecting airbag is in a cylindrical shape. The squeezing airbag is in a semi-cylindrical shape. The surfaces of adjacent squeezing airbags are fixedly connected and communicated with the surface of the connecting airbag.

[0006] Through the above technical solution, the lower ends of the two squeezing airbags are separated from each other, so as to facilitate the lower end of the airbag to fit the surface of the trigger bar.

[0007] Preferably, a trigger rod is fixedly inserted on the surface of the connecting airbag. One end surface of the connecting airbag is fixedly connected and communicated with the outer surface of one end of the adjusting column. One end of the trigger rod is slidably inserted into the end surface of the adjusting column. A snap ring is fixedly connected to the inner wall of the adjusting column. A sealing plug is fixedly connected to one end of the trigger rod.

[0008] Through the above technical solution, by fixedly inserting and sealing the surface of the trigger rod with the surface of the connecting airbag, and the airbag can be made of an elastic material, it is convenient to prevent air from leaking out while facilitating the movement of the trigger rod.

[0009] Preferably, a mounting rod is fixedly connected to the inner wall of the adjusting column. A thrust spring is fixedly connected to the surface of the mounting rod. The movable end of the thrust spring is fixedly connected to the surface of the sealing plug.

[0010] Through the above technical solution, since neither the mounting rod nor the sealing plug blocks the inside of the adjusting column, it is convenient for air to circulate inside the adjusting column.

[0011] Preferably, a driving rod is fixedly connected to one end surface of the material transporting column. Threads are provided on the inner wall of the driving rod. A lead screw is threadedly connected to the inner wall of the driving rod. The lead screw is in the shape of a hollow circular tube with an open end. One end of the lead screw is rotatably connected to an air column through a bearing. One end of the air column is fixedly connected and communicated with the end surface of the adjusting column.

[0012] Through the above technical solution, by applying the threads on the inner wall of the driving rod to the lead screw, it is convenient to cause the lead screw to rotate by itself when the lead screw moves.

[0013] Preferably, a contraction spring is fixedly connected to the inner wall of the lead screw. The inner wall of the contraction spring is slidably sleeved on the outer surface of the air column. The movable end of the contraction spring is fixedly connected to the end surface of the adjusting column. A cleaning column is fixedly connected to one end surface of the lead screw. The cleaning column is composed of a ceramic column with a silicone coating on its outer surface.

[0014] Through the above technical solution, the cleaning column is used to bond and clean the impurities in the valve tappet component, which is convenient for maintaining the valve tappet component. A magnetic ring can also be installed on the inner wall of the driving rod to facilitate the directional absorption of metal debris on the surface of the cleaning column.

[0015] Preferably, an extrusion plate is fixedly connected to the inner wall of the installation groove. The surface of the extrusion plate is in sliding contact with the surface of the extrusion airbag. A trigger strip is fixedly connected to the surface of the extrusion plate. Both the trigger strip and the extrusion plate are in a semi-circular ring shape.

[0016] Through the above technical solution, since the ends of the extrusion plate and the trigger strip are not aligned, it is convenient for the extrusion airbag to be inflated and deflated at a fixed position.

[0017] Preferably, a limiting block is fixedly connected to the upper surface of the lower end of the discharge pipe, and a limiting strip is rotatably connected to the upper surface of the lower end of the discharge pipe through a rotating shaft.

[0018] Through the above technical solution, the limiting strip is connected to the upper surface of the lower end of the discharge pipe through a snap spring, so as to facilitate the limiting strip to always deflect towards the surface of the limiting block.

[0019] Preferably, a blanking hose is fixedly connected to the upper end of the discharge pipe, the upper end of the blanking hose is fixedly connected to the blanking pipe of the vibrating blanking machine, and a telescopic rod is fixedly connected to the lower end of the discharge pipe.

[0020] Through the above technical solution, the vibrating blanking machine and the discharge pipe are connected by the blanking hose, so as to facilitate avoiding the discharge pipe being driven by the vibrating blanking machine to shake.

[0021] A processing method of a valve tappet processing device, step one, start the vibrating blanking machine, the vibrating blanking machine arranges the quenched valve tappet original parts, and enters the discharge pipe through the blanking hose. The limiting block cooperates with the limiting strip to block the falling of the valve tappet original parts. Start the driving motor, and the driving motor drives the material conveying disc to rotate on the surface of the mounting disc. The material conveying column moves to the surface of the extrusion plate under the drive of the mounting disc, and the extrusion plate compresses the extrusion airbag; Step two, after the opening of the driving rod is aligned with the lower end opening of the discharge pipe, the driving motor stops. At the same time, one end of the trigger rod slides to the surface of the trigger strip, and the trigger strip squeezes the trigger rod into the adjusting column. The trigger rod drives the sealing plug to separate from the snap ring, and the thrust spring is compressed. The air in the extrusion airbag flows into the air column through the adjusting column. The air column extends and pushes the lead screw. The contraction spring is stretched. The lead screw rotates under the action of the driving rod. The cleaning column extends into the discharge pipe under the drive of the lead screw, and pushes the limiting strip away. The cleaning column further penetrates into the valve tappet original part, rotates simultaneously, and bonds inside the valve tappet original part; Step three, start the driving motor, the material conveying disc drives the material conveying column to rotate upwards, and the cleaning column takes the valve tappet original part away from the discharge pipe. When moving to the other end of the mounting disc, the driving motor stops. The surface of the extrusion airbag loses the extrusion of the extrusion plate, and the gas in the air column flows into the extrusion airbag under the extrusion of the contraction spring. The cleaning column contracts into the driving rod under the drive of the lead screw, and the valve tappet original part is extruded and falls off outward by the inner wall of the driving rod; Step four, start the driving motor, the driving motor drives the material conveying disc to continue rotating, the trigger rod slides over the surface of the trigger strip and separates from the trigger strip, the thrust spring resets, and pushes the sealing plug to block the opening on the surface of the snap ring. The air in the extrusion airbag is isolated from the air in the air column. Repeat the above steps to work continuously.

[0022] The beneficial effects in the present invention are: 1. By setting up a transfer mechanism to extract the quenched valve tappet components, and while driving them through a cleaning column, the cleaning column drills into the interior of the valve tappet components. At the same time, the telescoping of the cleaning column is accompanied by its own rotation, so as to be able to clean the impurities inside the valve tappet components. Thus, while the transfer mechanism moves the valve tappet components, it cleans the interior of the valve tappet components, which is convenient for subsequent processing.

[0023] 2. By setting the discharge pipe in the blanking mechanism to be inclined, the quenched valve tappets can smoothly slide down along the inclined surface of the discharge pipe, and the sliding of the valve tappet components is blocked unidirectionally by the limiting strip, so as to facilitate the control of the blanking of the valve tappet components, and thus facilitate the extraction by the transfer mechanism.

[0026] 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Refer to Figures 1-8 , a valve tappet processing device and its processing method, including a vibrating blanking machine 1 and a base 2. A transfer mechanism is installed on the upper surface of the base 2. The transfer mechanism includes a material transport plate 3. A mounting plate 4 is fixedly connected to the upper surface of the base 2. An installation groove is formed on the surface of the mounting plate 4. The axis of the installation groove is rotationally connected to the axis of the material transport plate 3 through a rotating shaft. A driving motor 31 is fixedly connected to the other side surface of the mounting plate 4. The output shaft of the driving motor 31 is in transmission connection with the rotating shaft on the surface of the material transport plate 3. The operation of the driving motor 31 can also be controlled by an external chassis using chip programming in the chassis, so as to facilitate the accurate operation of the driving motor 31. A blanking mechanism is installed on the surface of the blanking pipe of the vibrating blanking machine 1. The blanking mechanism includes a discharge pipe 5. The discharge pipe 5 is inclined, and a discharge groove 51 is formed at the lower end of the discharge pipe 5.

[0028] In order to inflate the air column 313, a material transport column 32 is fixedly connected to the surface of the material transport plate 3. An adjustment column 33 is fixedly inserted into the inner wall of the material transport column 32. The adjustment column 33 is in a hollow shape with both ends sealed. One end of the material transport column 32 is fixedly connected to an airbag. The airbag is located in the installation groove. The airbag includes a connecting airbag 34 and a squeezing airbag 35. The connecting airbag 34 is cylindrical, and the squeezing airbag 35 is semi-cylindrical. The surfaces of adjacent two squeezing airbags 35 are fixedly connected to and communicate with the surface of the connecting airbag 34. By using the lower ends of the two squeezing airbags 35 to be separated from each other, it is convenient for the lower end of the airbag to fit the surface of the trigger bar 7. A trigger rod 36 is fixedly inserted into the surface of the connecting airbag 34. One end surface of the connecting airbag 34 is fixedly connected to and communicates with the outer surface of one end of the adjustment column 33. One end of the trigger rod 36 is slidably inserted into the end surface of the adjustment column 33. A snap ring 37 is fixedly connected to the inner wall of the adjustment column 33. A sealing plug 38 is fixedly connected to one end of the trigger rod 36. By using the surface of the trigger rod 36 to be fixedly inserted into and sealed with the surface of the connecting airbag 34, the airbag can be made of an elastic material, so as to facilitate blocking the outward leakage of air while facilitating the movement of the trigger rod 36. A mounting rod 39 is fixedly connected to the inner wall of the adjustment column 33. A thrust spring 310 is fixedly connected to the surface of the mounting rod 39. The movable end of the thrust spring 310 is fixedly connected to the surface of the sealing plug 38. By using the fact that neither the mounting rod 39 nor the sealing plug 38 blocks the inside of the adjustment column 33, it is convenient for the air to flow inside the adjustment column 33.

[0029] To control the operation of the cleaning column 315, a driving rod 311 is fixedly connected to one end surface of the material conveying column 32. The inner wall of the driving rod 311 is provided with threads, and a lead screw 312 is threadedly connected to the inner wall of the driving rod 311. The lead screw 312 is in the shape of a hollow circular tube with an open end. The inner wall of the lead screw 312 is rotatably connected to an air column 313 through a bearing. One end of the air column 313 is fixedly connected and communicated with the end surface of the adjusting column 33. By using the threads on the inner wall of the driving rod 311 to act on the lead screw 312, it is convenient to cause the lead screw 312 to rotate self - when the lead screw 312 moves. A contraction spring 314 is fixedly connected to the inner wall of the lead screw 312. The inner wall of the contraction spring 314 is slidably sleeved on the outer surface of the air column 313. The movable end of the contraction spring 314 is fixedly connected to the end surface of the adjusting column 33. One end surface of the lead screw 312 is fixedly connected to a cleaning column 315. The cleaning column 315 is composed of a ceramic column wrapped with silica gel on the outer surface. The impurities in the valve tappet element are adhered and cleaned by the cleaning column 315, so as to facilitate the maintenance of the valve tappet element. A magnetic ring can also be installed on the inner wall of the driving rod 311 to facilitate the directional absorption of metal debris on the surface of the cleaning column 315.

[0030] To control the use of the airbag and the trigger rod 36, a pressing plate 6 is fixedly connected to the inner wall of the installation groove. The surface of the pressing plate 6 is in sliding contact with the surface of the pressing airbag 35. A trigger strip 7 is fixedly connected to the surface of the pressing plate 6. Both the trigger strip 7 and the pressing plate 6 are in a semi - circular ring shape. Since the end of the pressing plate 6 and the end of the trigger strip 7 are not aligned, it is convenient for the pressing airbag 35 to be inflated and deflated at a fixed position.

[0031] By setting up a transfer mechanism to extract the quenched valve tappet element, and while being driven by the cleaning column 315, the cleaning column 315 drills into the valve tappet element. At the same time, the expansion and contraction of the cleaning column 315 are accompanied by its own rotation. Furthermore, the impurities in the valve tappet element can be cleaned, so that while the transfer mechanism moves the valve tappet element, the inside of the valve tappet element is cleaned, which is convenient for subsequent processing.

[0032] To discharge the valve tappet element, a limit block 52 is fixedly connected to the upper surface of the lower end of the discharge pipe 5. The upper surface of the lower end of the discharge pipe 5 is rotatably connected to a limit strip 53 through a rotating shaft. The limit strip 53 is connected to the upper surface of the lower end of the discharge pipe 5 through a snap ring, so as to facilitate the limit strip 53 to always deflect towards the surface of the limit block 52. The upper end of the discharge pipe 5 is fixedly connected to a blanking hose 54. The upper end of the blanking hose 54 is fixedly connected to the blanking pipe of the vibrating blanking machine 1. The lower end of the discharge pipe 5 is fixedly connected to a telescopic rod 55. By using the blanking hose 54 to connect the vibrating blanking machine 1 and the discharge pipe 5, it is convenient to prevent the vibrating blanking machine 1 from driving the discharge pipe 5 to vibrate.

[0033] By setting the discharge pipe 5 in the blanking mechanism to be inclined, the quenched valve tappets can smoothly slide down along the inclined surface of the discharge pipe 5, and the limiting strip 53 unidirectionally blocks the sliding of the valve tappet components, thereby facilitating the control of the blanking of the valve tappet components and further facilitating the extraction by the transfer mechanism.

[0034] Working principle: Step 1, start the vibrating blanking machine 1. The vibrating blanking machine 1 arranges the quenched valve tappet components and feeds them into the discharge pipe 5 through the blanking hose 54. The limiting block 52 and the limiting strip 53 cooperate to hinder the falling of the valve tappet components. Start the driving motor 31. The driving motor 31 drives the material conveying disk 3 to rotate on the surface of the mounting disk 4, and the material conveying column 32 moves to the surface of the pressing plate 6 under the drive of the mounting disk 4. The pressing plate 6 compresses the pressing air bag 35.

[0035] Step 2, after the opening of the driving rod 311 is aligned with the lower opening of the discharge pipe 5, the driving motor 31 stops. At the same time, one end of the trigger rod 36 slides onto the surface of the trigger strip 7. The trigger strip 7 squeezes the trigger rod 36 into the adjusting column 33. The trigger rod 36 drives the sealing plug 38 to separate from the snap ring 37, and the thrust spring 310 is compressed. The air in the pressing air bag 35 flows into the air column 313 through the adjusting column 33. The air column 313 extends and pushes the lead screw 312. The compression spring 314 is stretched. The lead screw 312 rotates automatically under the action of the driving rod 311. The cleaning column 315 extends into the discharge pipe 5 under the drive of the lead screw 312, pushes open the limiting strip 53, and further penetrates into the valve tappet component. At the same time, it rotates automatically and adheres to the inside of the valve tappet component.

[0036] Step 3, start the driving motor 31. The material conveying disk 3 drives the material conveying column 32 to rotate upward. The cleaning column 315 takes the valve tappet component away from the discharge pipe 5. When it moves to the other end of the mounting disk 4, the driving motor 31 stops. The surface of the pressing air bag 35 loses the extrusion of the pressing plate 6. The gas in the air column 313 flows into the pressing air bag 35 under the extrusion of the compression spring 314. The cleaning column 315 contracts into the driving rod 311 under the drive of the lead screw 312, and the valve tappet component is extruded and falls off outward by the inner wall of the driving rod 311.

[0037] Step 4, start the driving motor 31. The driving motor drives the material conveying disk 3 to continue rotating. The trigger rod 36 slides over the surface of the trigger strip 7 and separates from the trigger strip 7. The thrust spring 310 resets and pushes the sealing plug 38 to block the opening on the surface of the snap ring 37. The air in the pressing air bag 35 is isolated from the air in the air column 313. Repeat the above steps for continuous operation.

[0038] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
