Description

Technical Field

[0001] The invention relates to the technical field of valve processing, and in particular to a valve cone surface processing device. Background Art

[0002] The valve is an important part of the engine. With more stringent emission requirements, in order to reduce emissions and improve the thermal efficiency of the engine, the base material used for the valve has been gradually replaced by nickel-based alloy base material 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 of nickel-based alloy materials. The grinding of the valve cone surface is a key process in valve processing. During the grinding process of the valve cone surface, the valve is clamped in the workpiece spindle and rotated by the spindle, cooperating with the high-speed rotating grinding wheel to fully grind the cone surface of the valve.

[0003] The prior art discloses a CBN valve conical surface grinding machine with a publication number of CN112658834A. The CBN valve conical surface grinding machine automatically feeds, delivers and discharges materials through an active component material rack, which is convenient for rapid loading and unloading of materials as a whole, increases the overall loading and unloading speed, thereby increasing the overall processing speed, and is convenient for rapid processing and forming of the workpiece as a whole. The product is clamped by a cylinder and sent into a precision fixture. The fixture is clamped and rotated, and the ceramic CBN grinding wheel quickly approaches the workpiece for high-speed grinding, ensuring rapid and stable clamping of the whole, increasing the stability of the whole during clamping, and ensuring a good overall processing effect. After the product is ground, the grinding wheel quickly retreats and the workpiece is discharged. This cycle of processing facilitates rapid processing and forming of the whole.

[0004] Although the above-mentioned 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, the valve is directly placed on the discharge track for unloading after the valve processing is completed. Then, after the valve comes out of the track, workers are required to take it out one by one and put it in the material box, which is not only time-consuming and labor-intensive, but also greatly reduces the convenience of the device.

[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In the following description, many specific details are set forth to facilitate 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 present invention is not limited to the specific embodiments disclosed below.

[0021] like Figure 1-Figure 10 A valve cone surface processing device shown in the figure includes a cabinet 1 and a valve feeding mechanism 2 arranged in the cabinet 1. The valve feeding mechanism 2 mainly uses pneumatic components, such as a cylinder or a pneumatic finger, and uses the power generated by compressed air to grab and move the workpiece (valve), and then inserts the valve into a clamping and rotating mechanism 3. It 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 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 the grinding. At the same time, it has a valve rotation function, which makes it easy for the grinding mechanism 4 to fully grind the valve cone surface. A grinding mechanism 4 for grinding the valve cone surface is provided in the cabinet 1. The grinding mechanism 4 is mainly composed of a motor, a grinding disc and a moving mechanism. It can automatically drive the grinding disc to rotate to grind the valve cone surface, and the grinding disc is driven by the moving mechanism to move to the valve cone surface, and the valve is fully polished in cooperation with the operation of the clamping and rotating mechanism 3. The outer wall of the cabinet 1 is provided with a discharge port, the top of the discharge port 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, and a rotating plate 9 is rotatably connected with the side wall of the fixed frame 8, and a clamping mechanism 10 for clamping the valve is provided on the rotating plate 9. The clamping mechanism 10 is mainly composed of a motor and a clamping plate and other structures, which is a mature technology in the prior art and is not described in detail here. A driving mechanism for driving the fixed frame 6 to move is provided on the top plate 5, and a round rod 13 is slidably connected through the top end of the sliding cylinder 7, and a transverse groove 14 and a U-shaped groove 16 are respectively provided at the bottom end of the top plate 5, an L-shaped groove 15 is provided at one end of the transverse 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, and an inclined groove 17 is provided between the other end of the U-shaped groove 16 and the other end of the transverse groove 14; The side wall of the fixed frame 8 is fixedly connected with a rotating motor 11, and the output end of the rotating motor 11 passes through the side wall of the fixed frame 8 and is fixedly connected with 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 frame 27. The side wall of the sliding cylinder 7 is fixedly connected with an upper electric telescopic cylinder 12, and the output end of the upper electric telescopic cylinder 12 is fixedly connected to the top of the fixed frame 8. Through the setting of the upper electric telescopic cylinder 12, it is convenient to insert the valve into the slot for unloading; The top of the transverse groove 14 near the inclined groove 17 is provided with an inwardly sunken groove 18, and the connection between the groove 18 and the top of the transverse groove 14 is inclined, the top 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 inner bottom end of the sliding cylinder 7 and the bottom end of the round rod 13, and the top of the round rod 13 is set as a smooth arc surface, so that the round rod 13 can slide out along the inclined surface of the groove 18, and 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; A first touch sensor 20 is fixedly connected through the corner of the L-shaped groove 15, and the first touch sensor 20 is electrically connected to the clamping rotation mechanism 3, the drive motor 23 and the clamping mechanism 10 through the controller. A second touch sensor 21 and a third touch sensor 22 are respectively fixedly connected through the two sides of the lateral end of the U-shaped groove 16, and the second touch sensor 21 is electrically connected to the rotating motor 11 through the controller, and the third touch sensor 22 is electrically connected to the upper electric telescopic cylinder 12 and the drive motor 23 through the controller. 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 one of the side walls 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 provided on the side wall of the fixing frame 6. The threaded rod 25 is threadedly connected to the threaded groove through its threaded portion. During the grinding process of the conical surface of the valve, the valve is first inserted into the clamping and rotating mechanism 3 through the valve feeding mechanism 2, and the valve is clamped by the clamping and rotating mechanism 3, and then 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 and 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 threaded fixed frame 6 to move under the top plate 5 (it should be noted here that in the initial position, the round rod 13 in the sliding cylinder 7 is located in the transverse groove 14 and close to the side of the L-shaped groove 15, so that the valve can be quickly taken out in the subsequent operation, saving processing time and improving production efficiency), and at the same time, the sliding cylinder 7, the fixed frame 8 and the rotating plate 9 on the side wall of the fixed frame 6 are driven to move, and at the same time, the round rod 13 is driven to move to the connection between the transverse groove 14 and the L-shaped groove 15, thereby releasing the squeezing of the round rod 13; Then, under the elastic force of the lower spring 41, the round rod 13 is pulled to slide into the L-shaped groove 15, and the sliding cylinder 7, the fixing frame 8 and the upper electric telescopic cylinder 12 are driven to move, so that the clamping plate of the clamping mechanism 10 moves 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 touches the first touch sensor 20. Then the first touch sensor 20 transmits a signal to the controller, and the controller controls the clamping mechanism 10 to clamp the valve in turn, and then controls the clamping rotation mechanism 3 to release the fixation of the valve, and then controls the driving motor 23 to reverse, driving the threaded fixed frame 6 to move in the opposite direction and move out of the cabinet. The valve body 1 is in the inner part of the valve body 1, and the round rod 13 is driven to slide at the lateral end of the L-shaped groove 15, and the valve is pulled out from the clamping and rotating mechanism 3. At the same time, the controller can control the operation of the valve feeding mechanism 2 to feed and grind the valve for seamless connection processing. With the continued 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, and then squeeze the round rod 13 to slide backward through the inclined surface of the inclined end of the U-shaped groove 16, and drive the sliding cylinder 7 to move, and gradually compress the lower spring 41, thereby driving the valve to move backward (to facilitate the subsequent removal of the clamping mechanism 10 from the valve); Then the round rod 13 moves to the lateral end of the U-shaped groove 16, at which time it touches the second touch sensor 21, and then transmits a signal to the controller. The controller controls the rotating 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 to the bottom (to facilitate subsequent insertion into the slot in the material frame 27). Then, before the round rod 13 moves to the other end of the lateral groove of the U-shaped groove 16, it touches the third touch sensor 22. At this time, the valve moves to the top of the slot of the material frame 27, and then transmits a signal to the controller. The controller controls the drive motor 23 to stop running in turn, and then controls the upper motor 23 to stop running. The telescopic cylinder 12 starts to drive the fixing frame 8 and the rotating plate 9 to move downward, thereby inserting the valve into the slot. After the upper electric telescopic cylinder 12 finishes running, 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, thereby releasing the squeezing of the round rod 13, and then the round rod 13 is pushed out of the longitudinal end of the U-shaped groove 16 under the elastic force of the lower spring 41, and the sliding cylinder 7 is driven to move forward, so that the clamping mechanism 10 is moved away from the valve, and then the round rod 13 slides into the inclined groove 17, thereby gradually squeezing the round rod 13 forward through the inclined surface of the inclined groove 17; At the same time, the sliding cylinder 7 and the fixing frame 8 are driven to move forward, and the lower spring 41 is gradually stretched, and then the round rod 13 slides out of the inclined groove 17, and then slides into the transverse groove 14, and is located above the groove 18, so that the top end of the round rod 13 is pushed into the groove 18 under the elastic force of the upper spring 19. Since there is a step between the groove 18 and the inclined groove 17, it is restricted, which will hinder the round rod 13 from sliding into the inclined groove 17. Finally, the driving motor 23 is controlled 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 squeeze the round rod 13 upward to move, while compressing the upper spring 19, and then the round rod 13 moves to the initial position. This is repeated to achieve automatic unloading and sorting of the valve.

[0022] In order to automatically push the material frame 27 to move and change the slot position, a material unloading platform 26 is provided on the outer wall of the cabinet 1 and below the top plate 5. The material unloading platform 26 is provided with a material frame 27 for arranging the valves. The material frame 27 is provided with a plurality of slots for inserting and releasing the valves at equal intervals. A front plate 28 is fixedly connected to the front side of the unloading platform 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 on the top of the unloading platform 26. It should be noted that an electromagnet is provided inside the U-shaped plate 30, and the material frame 2 7 is a material that can be adsorbed by a magnet, so as to avoid the material frame 27 from being pulled back to reset when the lower electric telescopic cylinder 29 is reset, and will not affect the lower electric telescopic cylinder 29 from pushing the material frame 27 to the conveying mechanism 40. The material frame 27 is inserted into the inner side of the U-shaped plate 30, and a transverse plate 31 is provided on the unloading platform 26, and the U-shaped plate 30 is slidably connected to the rear side of the transverse plate 31, and 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 transverse plate 31, and a push frame mechanism for the fixed frame 6 to push and change the material discharge position is provided on the U-shaped plate 30; The push frame mechanism includes a push rod 32, which is fixedly connected to the bottom end of the fixed frame 6. A top groove is formed at the top of the U-shaped plate 30, and a limit plate 33 is fixedly connected to the inner side of the top groove. A plurality of push rods 34 are rotatably connected to the inner side of the top groove at equal intervals. A plurality of push rods 34 are tilted and fixedly connected to the side away from the cabinet 1. An extrusion plate 35 is fixedly connected. It should be noted that the weight of the extrusion plate 35 needs to be set to twice the weight of the push rod 34 to prevent the extrusion plate 35 from flipping over when the L-shaped plate 36 pushes the push rod 34 to flip to the other side, thereby affecting the normal operation of the device. The bottom ends of the extrusion plates 35 are all against the top of the limit plate 33. A slide groove is formed at the top of the cross plate 31, and an L-shaped plate 36 is slidably connected to the inner side of the slide groove. A return spring 37 is fixedly connected between the side wall of the L-shaped plate 36 and the inner side of the slide groove. A fourth touch sensor 38 is fixedly connected to the inner side of the slide groove. A conveying frame 39 is provided at the rear side of the unloading platform 26, and a conveying mechanism 40 for conveying the material frame 27 is provided on the conveying frame 39. When the valve is inserted into the slot, the driving motor 23 is controlled to rotate forward to drive the sliding cylinder 7 to reset, and the lower electric telescopic cylinder 29 is controlled to start (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 unloading position), driving the cross plate 31 to move backward, and at the same time pushing the U-shaped plate 30 and the material frame 27 to move backward, thereby changing the position of the slot, pushing the slot into which the valve is inserted backward, and avoiding affecting the normal unloading of the subsequent valve; This is repeated. When the longitudinal slots on the material frame 27 are full, the L-shaped plate 36 on the horizontal plate 31 will move to the side of the push rod 32. When the valve is placed in the last slot, the driving motor 23 drives the round rod 13 to move into the groove 18. The push rod 32 under the fixed frame 6 will push the L-shaped plate 36 to move, and then the push rod 34 will be driven to move through 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 is against the top end of the limit plate 33, the push rod 34 will be limited. The flip position of the L-shaped plate 36 drives the push rod 34 and the U-shaped plate 30 to move, and drives the material frame 27 to move, and moves another set of slots to the valve unloading position, and gradually compresses the return spring 37, and then the L-shaped plate 36 moves to the other end of the slide slot and touches the fourth touch sensor 38 (it should be noted that the length of the fourth touch sensor 38 is set to be greater than the length of the return spring 37 after compression, so as to avoid the phenomenon that the L-shaped plate 36 cannot touch the fourth touch sensor 38); The signal is then transmitted to the controller, and the controller controls the electric telescopic cylinder 29 to operate and pull the cross plate 31 to move in the opposite direction for reset, and at the same time drive the electromagnet in the U-shaped plate 30 to adsorb the material frame 27, and then pull the material frame 27 forward for reset. Subsequently, when the driving motor 23 drives the fixed frame 6 to reset, the extrusion of the L-shaped plate 36 will be gradually released, and then the L-shaped plate 36 will be gradually pushed to reset under the elastic force of the reset spring 37. Subsequently, when the L-shaped plate 36 moves to the rear push rod 34, 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 over, but 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, and the push rod 34 will be close to the L-shaped The bottom end of the plate 36, and then when the L-shaped plate 36 is removed, the push rod 34 is pulled to flip and reset under the gravity of the extrusion plate 35, and this is repeated to further change the unloading position of the material frame 27. Finally, when the material frame 27 is full, the lower electric telescopic cylinder 29 can be controlled to push the material frame 27 onto the conveying mechanism 40, and then the electromagnet is turned off, and then the lower electric telescopic cylinder 29 is controlled to reset and retract the cross plate 31, and the conveying mechanism 40 can be controlled to start to transport the material frame 27 away, and then the empty material frame 27 is placed on the unloading table 26, and the U-shaped plate 30 needs to be pushed back at the same time (it should be noted that when pushing the U-shaped plate 30 back, it is necessary to press the push rod 34 to flip it in turn, release the extrusion of the L-shaped plate 36, and push the U-shaped plate 30 back to its original position).
