Description

Technical Field

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

[0002] The valve is an important component of the engine. In order to reduce emissions and improve the thermal efficiency of the engine, the base materials used for valves have gradually been replaced by nickel-based alloy base materials from the original ordinary martensitic steel and austenitic steel. Ordinary abrasives no longer have the ability to process high-temperature nickel-based alloy materials. Therefore, ceramic CBN abrasives have been developed to cope with the grinding processing of nickel-based alloy materials. The grinding processing of the valve conical surface is a key process in valve processing. During the grinding processing of the valve conical surface, the valve is clamped in the workpiece spindle and rotated by the spindle to cooperate with the high-speed rotating grinding wheel to comprehensively polish the conical surface of the valve.

[0003] In the prior art, there is a CBN valve precision grinding conical surface grinding machine with the publication number of CN112658834A. This CBN valve precision grinding conical surface grinding machine automatically feeds, transports, and discharges through the active element rack, which facilitates the overall rapid loading and unloading, increases the overall loading and unloading speed, and thus increases the overall processing speed, facilitating the overall rapid processing and forming of the workpiece. The product is clamped and sent into the precision fixture by the cylinder, the fixture clamps and rotates, and the ceramic CBN grinding wheel quickly approaches the workpiece for high-speed grinding, ensuring the overall rapid and stable clamping, increasing the stability during the overall clamping, ensuring the overall good processing effect, and after the product is ground, the grinding wheel quickly retreats and the workpiece is discharged, and so on for cyclic processing, facilitating the overall rapid processing and forming.

[0004] Although the above device can automatically load and unload valves, there are still some defects in the actual processing process. Due to the automatic loading and unloading structure of the device, after the valve processing is completed, the valve is directly placed on the discharge conveyor belt for unloading. Then, after the valve comes out of the conveyor belt, workers need to take them out one by one and place them in the material box, which is not only time-consuming and laborious, but also greatly reduces the convenience performance of the device.

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0031] As Figures 1-10 shown, a valve cone surface machining device includes a cabinet body 1 and a valve feeding mechanism 2 arranged in the cabinet body 1. The valve feeding mechanism 2 mainly uses pneumatic components such as cylinders or pneumatic fingers to grab and move the workpiece (valve) by using the power generated by compressed air, and then inserts the valve into the clamping and rotating mechanism 3. This is a mature technology in the prior art and will not be described in detail here. A clamping and rotating mechanism 3 for clamping the valve is provided in the cabinet body 1. The clamping and rotating mechanism 3 can firmly fix the valve to ensure that the valve does not move during the grinding process, thereby ensuring the accuracy and safety of grinding. At the same time, it has the function of rotating the valve, which is convenient for the grinding mechanism 4 to comprehensively grind the valve cone surface. A grinding mechanism 4 for grinding the valve cone surface is provided in the cabinet body 1. The grinding mechanism 4 mainly consists of a motor, a grinding disc and a moving mechanism, which can automatically drive the grinding disc to rotate, grind the valve cone surface, and drive the grinding disc to move to the valve cone surface through the moving mechanism. Cooperating with the operation of the clamping and rotating mechanism 3, the valve is comprehensively ground;

[0032] An outlet is provided on the outer wall of the cabinet body 1. The top end of the outlet is fixedly connected with a top plate 5. The bottom end of the top plate 5 is slidably connected with a fixed frame 6. The inner side of the fixed frame 6 is slidably connected with a sliding cylinder 7. A fixed frame 8 is provided below the sliding cylinder 7. A rotating plate 9 is rotatably connected to the side wall of the fixed frame 8. A clamping mechanism 10 for clamping the valve is provided on the rotating plate 9. The clamping mechanism 10 mainly consists of a motor and clamping plates and other structures. This is a mature technology in the prior art and will not be described in detail here. A driving mechanism for driving the fixed frame 6 to move is provided on the top plate 5. A round rod 13 is slidably connected through the top end inside the sliding cylinder 7. Horizontal grooves 14 and U-shaped grooves 16 are respectively opened at the bottom end of the top plate 5. An L-shaped groove 15 is opened at one end of the horizontal groove 14, and one end of the U-shaped groove 16 is inclined and connected to the other end of the L-shaped groove 15. An inclined groove 17 is opened between the other end of the U-shaped groove 16 and the other end of the horizontal groove 14;

[0033] A rotating motor 11 is fixedly connected to the side wall of the fixing frame 8. The output end of the rotating motor 11 passes through the side wall of the fixing frame 8 and is fixedly connected to the side wall of the rotating plate 9. Through the setting of the rotating motor 11, the clamped valve can be turned over so that the long handle end faces downward, which is convenient for subsequent insertion into the slot of the material box 27. An upper electric telescopic cylinder 12 is fixedly connected to the side wall of the sliding cylinder 7, and the output end of the upper electric telescopic cylinder 12 is fixedly connected to the top end of the fixing frame 8. Through the setting of the upper electric telescopic cylinder 12, it is convenient to insert the valve into the slot for blanking;

[0034] A recessed groove 18 is formed at the top end of the transverse groove 14 near one end of the inclined groove 17, and the connection between the groove 18 and the top end of the transverse groove 14 is inclined. The top end of the round rod 13 is inserted into the inner side of the transverse groove 14. An upper spring 19 is fixedly connected between the bottom end inside the sliding cylinder 7 and the bottom end of the round rod 13. The top of the round rod 13 is provided with a smooth arc surface, which is convenient for the round rod 13 to slide out along the inclined surface of the groove 18. A pair of lower springs 41 are fixedly connected between the inner side of the fixed frame 6 and the side wall of the sliding cylinder 7;

[0035] A first touch sensor 20 is fixedly connected through the corner of the L-shaped groove 15. The first touch sensor 20 is electrically connected to the clamping and rotating mechanism 3, the driving motor 23, and the clamping mechanism 10 through a controller. The second touch sensor 21 and the third touch sensor 22 are respectively fixedly connected through the two sides of the transverse end of the U-shaped groove 16. The second touch sensor 21 is electrically connected to the rotating motor 11 through a controller, and the third touch sensor 22 is electrically connected to the upper electric telescopic cylinder 12 and the driving motor 23 through a controller;

[0036] The driving mechanism includes a driving motor 23. Side plates 24 are fixedly connected to both sides of the outer wall of the top plate 5. A threaded rod 25 is rotatably connected between the side plates 24. The driving motor 23 is fixedly connected to the side wall of one of the side plates 24. The output end of the driving motor 23 passes through the side wall of the side plate 24 and is fixedly connected to the side wall of the threaded rod 25. A threaded groove is formed on the side wall of the fixed frame 6, and the threaded rod 25 is threadedly connected to the threaded groove through its threaded part;

[0037] During the grinding process of the conical surface of the valve, first, the valve is inserted into the clamping and rotating mechanism 3 through the valve feeding mechanism 2. The valve is clamped by the clamping and rotating mechanism 3. Subsequently, the grinding mechanism 4 is controlled to operate to grind the conical surface of the valve. At the same time, the clamping and rotating mechanism 3 drives the valve to rotate to comprehensively grind the conical surface of the valve. After the grinding is completed, the driving motor 23 can be controlled to start and drive the threaded rod 25 to rotate, thereby driving the fixedly connected frame 6 to move below the top plate 5 (it should be noted here that at the initial position, the round rod 13 in the sliding cylinder 7 is located in the transverse groove 14 and close to one side of the L-shaped groove 15, which can quickly remove the valve during subsequent operation, saving processing time and improving production efficiency). At the same time, it drives the sliding cylinder 7, the fixed frame 8, and the rotating plate 9 on the side wall of the fixedly connected frame 6 to move, and at the same time drives the round rod 13 to move to the connection of the transverse groove 14 and the L-shaped groove 15, thereby releasing the extrusion on the round rod 13;

[0038] Subsequently, under the elastic force of the lower spring 41, the round rod 13 is pulled into the L-shaped groove 15, and drives the sliding cylinder 7, the fixed frame 8, and the upper electric telescopic cylinder 12 to move, so that the clamping plates of the clamping mechanism 10 move to the upper and lower sides of the valve. At this time, the round rod 13 moves to the corner of the L-shaped groove 15, and the round rod 13 will touch the first touch sensor 20. Subsequently, the first touch sensor 20 transmits a signal to the controller, and the controller sequentially controls the clamping mechanism 10 to clamp the valve, then controls the clamping and rotating mechanism 3 to release the fixation of the valve. Subsequently, the driving motor 23 is controlled to reverse, driving the fixedly connected frame 6 connected by threads to move out of the cabinet body 1 in the reverse direction, and at the same time driving the round rod 13 to slide in the transverse end of the L-shaped groove 15 to pull out the valve from the clamping and rotating mechanism 3. At the same time, the controller can control the valve feeding mechanism 2 to operate to feed and grind the valve for seamless connection processing. With the continuous driving of the driving motor 23, the round rod 13 will slide out of the L-shaped groove 15 and then slide into the inclined end of the U-shaped groove 16. Then, the inclined surface of the inclined end of the U-shaped groove 16 squeezes the round rod 13 to slide backward, driving the sliding cylinder 7 to move, and at the same time gradually compressing the lower spring 41, thereby driving the valve to move backward (facilitating the subsequent removal of the clamping mechanism 10 from the valve);

[0039] Then the round rod 13 moves to the lateral end of the U-shaped groove 16. At this time, it will touch the second touch sensor 21, and then transmit a signal to the controller. The controller controls the rotation motor 11 to start and drive the rotating plate 9 to rotate, thereby driving the clamping mechanism 10 and the valve to rotate, and flipping the long handle end of the valve downward (facilitating subsequent insertion into the slot in the material box 27). Subsequently, before the round rod 13 moves to the other end of the lateral groove of the U-shaped groove 16, it will touch the third touch sensor 22. At this time, the valve moves above the slot of the material box 27, and then transmits a signal to the controller. The controller sequentially controls the driving motor 23 to stop running, and then controls the upper electric telescopic cylinder 12 to start and drive the fixing frame 8 and the rotating plate 9 to move downward, thereby inserting the valve into the slot. Subsequently, after the operation of the upper electric telescopic cylinder 12 ends, the controller controls the clamping mechanism 10 to release the clamping of the valve, and then controls the driving motor 23 to continue running, thereby driving the round rod 13 to move to the corner of the U-shaped groove 16, thus releasing the extrusion on the round rod 13. Then, under the elastic force of the lower spring 41, the round rod 13 is pushed out of the longitudinal end of the U-shaped groove 16 and drives the sliding cylinder 7 to move forward, so that the clamping mechanism 10 moves away from the valve. Subsequently, the round rod 13 slides into the inclined groove 17, and thus is gradually pushed forward by the inclined surface of the inclined groove 17 to move the round rod 13 forward;

[0040] At the same time, it drives the sliding cylinder 7 and the fixing frame 8 to move forward and gradually stretches the lower spring 41. Subsequently, the round rod 13 slides out of the inclined groove 17, then slides into the transverse groove 14 and is located above the groove 18. Thus, under the elastic force of the upper spring 19, the top of the round rod 13 is pushed into the groove 18. Due to the step between the groove 18 and the inclined groove 17, it will prevent the round rod 13 from sliding into the inclined groove 17. Finally, control the driving motor 23 to rotate forward to drive the round rod 13 to move to the initial position. During this process, the round rod 13 will slide out along the inclined surface of the groove 18 and gradually push the round rod 13 upward to move, while compressing the upper spring 19. Subsequently, the round rod 13 moves to the initial position. Repeating this process can achieve automatic blanking and sorting of the valve.

[0041] In order to automatically push the material frame 27 to move and change the slot position, a blanking table 26 is provided on the outer wall of the cabinet body 1 and below the top plate 5. A material frame 27 for sorting valves is provided on the blanking table 26. A number of slots for inserting valves are equidistantly arranged on the material frame 27. A front plate 28 is fixedly connected to the front side of the blanking table 26. A pair of lower electric telescopic cylinders 29 are fixedly connected to the front side of the front plate 28. A U-shaped plate 30 is provided at the top of the blanking table 26. Here, it should be noted that an electromagnet is provided inside the U-shaped plate 30, and the material frame 27 is made of a material that can be adsorbed by a magnet, so as to avoid that when the lower electric telescopic cylinder 29 resets, the material frame 27 cannot be pulled back for reset, and it will not affect the lower electric telescopic cylinder 29 to push the material frame 27 onto the conveying mechanism 40. The material frame 27 is inserted inside the U-shaped plate 30. A cross plate 31 is provided on the blanking table 26, and the U-shaped plate 30 is slidably connected to the rear side of the cross plate 31. The output end of the lower electric telescopic cylinder 29 passes through the rear side of the front plate 28 and is fixedly connected to the front side of the cross plate 31. A push frame mechanism for fixing the frame 6 to push and change the discharging position is provided on the U-shaped plate 30;

[0042] The push frame mechanism includes a push rod 32. The push rod 32 is fixedly connected to the bottom end of the fixed frame 6. A top slot is penetrated and opened at the top end of the U-shaped plate 30. A limiting plate 33 is fixedly connected to the inner side of the top slot. A number of top rods 34 are rotatably connected to the inner side of the top slot at equal intervals. A pressing plate 35 is fixedly connected to the inclined side of each of the number of top rods 34 away from the cabinet body 1. Here, it should be noted that the weight of the pressing plate 35 needs to be set to twice the weight of the top rod 34, so as to avoid that when the L-shaped plate 36 pushes the top rod 34 to flip to the other side, the pressing plate 35 will be driven to flip over, affecting the normal operation of the device. The bottom ends of the pressing plates 35 are all abutted against the top of the limiting plate 33. A chute is opened at the top end of the cross plate 31. An L-shaped plate 36 is slidably connected to the inner side of the chute. A return spring 37 is fixedly connected between the side wall of the L-shaped plate 36 and the inner side of the chute. A fourth touch sensor 38 is fixedly connected to the inner side of the chute. A conveying frame 39 is provided at the rear side of the blanking table 26. A conveying mechanism 40 for conveying the material frame 27 is provided on the conveying frame 39;

[0043] When the valve is inserted into the slot, while controlling the driving motor 23 to rotate forward to drive the sliding cylinder 7 to reset, control the lower electric telescopic cylinder 29 to start (here, it should be noted that the running distance of the lower electric telescopic cylinder 29 can be set by the program each time to accurately push the slot to the blanking position), drive the cross plate 31 to move backward, and at the same time push the U-shaped plate 30 and the material frame 27 to move backward, thereby changing the position of the slot and pushing the slot with the inserted valve backward to avoid affecting the normal blanking of the subsequent valves;

[0044] Repeat this process. When the vertical row of slots on the material frame 27 is full, the L-shaped plate 36 on the cross plate 31 will move next to the push rod 32. Then, after the valve is placed in the last slot and the driving motor 23 drives the round rod 13 to move into the groove 18, the push rod 32 below the fixed frame 6 will push the L-shaped plate 36 to move. Then, the push rod 34 will be driven to move by the L-shaped plate 36. Since the side wall of the push rod 34 is provided with an inclined extrusion plate 35 and the bottom end of the extrusion plate 35 abuts against the top end of the limiting plate 33, the flipping position of the push rod 34 will be restricted. Therefore, the push rod 34 and the U-shaped plate 30 will be driven to move under the push of the L-shaped plate 36, and the material frame 27 will be driven to move, moving another set of slots to the valve blanking position. At the same time, the return spring 37 will be gradually compressed. Subsequently, when the L-shaped plate 36 moves to the other end of the chute, it will touch the fourth touch sensor 38 (it should be noted here that the length of the fourth touch sensor 38 is set to be greater than the length after the return spring 37 is compressed to avoid the phenomenon that the L-shaped plate 36 cannot touch the fourth touch sensor 38).

[0045] Then, the signal will be transmitted to the controller, and the controller will control the electric telescopic cylinder 29 to operate to pull the cross plate 31 to move backward for reset. At the same time, the electromagnet in the U-shaped plate 30 will adsorb the material frame 27, and then the material frame 27 will be pulled forward to move for reset. Subsequently, when the driving motor 23 drives the fixed frame 6 to reset, the extrusion on the L-shaped plate 36 will be gradually released. Then, under the elastic force of the return spring 37, the L-shaped plate 36 will be gradually pushed to reset. Subsequently, when the L-shaped plate 36 moves next to the push rod 34 at the back, since there is no restriction on the other side of the push rod 34, the L-shaped plate 36 will push the push rod 34 to flip. However, the weight of the extrusion plate 35 is greater than the weight of the push rod 34, so the push rod 34 will not completely flip downward. The push rod 34 will closely adhere to the bottom end of the L-shaped plate 36. Then, after the L-shaped plate 36 moves away, under the gravity of the extrusion plate 35, the push rod 34 will be pulled to flip and reset. Repeat this process to further replace the blanking position of the material frame 27. Finally, when the material frame 27 is full, the electric telescopic cylinder 29 can be controlled to push the material frame 27 onto the conveying mechanism 40. After turning off the electromagnet, then control the electric telescopic cylinder 29 to reset and retract the cross plate 31, and then the conveying mechanism 40 can be controlled to start to convey the material frame 27 away. Then, place the empty material frame 27 on the blanking table 26, and at the same time, the U-shaped plate 30 needs to be pushed back (it should be noted here that when pushing back the U-shaped plate 30, it is necessary to press the push rod 34 to flip in sequence to release the extrusion on the L-shaped plate 36 and push the U-shaped plate 30 back to reset).
