Description

Technical Field

[0001] The invention belongs to the technical field of valve guide tube processing, and in particular relates to a valve guide tube directional conveying device. Background Art

[0002] The valve guide of the engine cylinder head guides the valve, ensuring that the valve makes reciprocating linear motion, so that the valve and the valve seat can fit correctly, and transfer the heat of the valve stem to the cylinder head. Figure 1 Some valve guides have annular grooves on their outer cylindrical surfaces. During assembly, the annular grooves are inserted into the inlet and exhaust valve stem seals to fasten the valve spring lower seat to prevent them from falling off. Due to the presence of the annular grooves, the directionality of the valve guides needs to be determined during installation. However, automatic detection of the directionality of the cylinder head valve guides has not yet been achieved, which is very inconvenient when the number of processes is large.

[0003] In order to quickly and accurately determine the direction of the valve guide and adjust its direction to be consistent with the final feeding direction, it is urgently necessary to propose a valve guide directional conveying device. Summary of the invention

Figure 3 The structure diagram of the direction detection device 200 according to the embodiment of the present invention at a certain viewing angle is schematically shown. Figure 4 The structure diagram of the moving slider 212 according to the embodiment of the present invention is schematically shown. Figures 1 to 4 The present invention proposes a valve guide directional conveying device, comprising a feeding device 100, a direction detection device 200 and a flip feeding device 300; the direction detection device 200 comprises a platform component 210 and a direction detection component 220, and the flip feeding device 300 comprises a flip component 310 and a feeding component 320; the feeding device 100 is used to convey the valve guide 10 to the platform component 210, the direction detection component 220 is used to determine the direction of the valve guide 10 on the platform component 210, the platform component 210 can convey the valve guide 10 to the flip component 310 according to the detection information of the direction detection component 220, the flip component 310 is configured to adjust the direction of the valve guide 10 according to the preset feeding direction and the detection information of the direction detection component 220, and the feeding component 320 Used to receive the valve guide 10 after the direction is adjusted by the flip assembly 310; the platform assembly 210 includes a guide platform 211, a movable slider 212 and a slider driving member 213, the outlet end of the guide platform 211 is arranged toward the flip assembly 310, the movable slider 212 is arranged on the guide platform 211, the slider driving member 213 is used to drive the movable slider 212 to move along the guide platform 211, the movable slider 212 has a positioning groove 212a with a bottom opening, the side of the movable slider 212 has a valve guide inlet, the valve guide inlet and the positioning groove 212a are connected, the valve guide 10 can be inserted into the positioning groove 212a through the valve guide inlet, and the movable slider 212 moves along the guide platform 211, so that the bottom opening of the positioning groove 212a can face the flip assembly 310.

[0021] During use, the valve guide directional conveying device provided by the technical solution conveys the valve guide 10 to the positioning groove 212a of the moving slider 212 through the feeding device 100, and the guide platform 211 supports the moving slider 212 and the valve guide 10. The direction of the valve guide 10 in the moving slider 212 is random. At this time, the direction detection component 220 determines the direction of the valve guide 10. Subsequently, the slider driving member 213 drives the moving slider 212 to move along the guide platform 211. After the positioning groove 212a moves out of the guide platform 211, the valve guide 10 falls from the bottom opening of the positioning groove 212a to the flip component 310. Then, the flip component 310 adjusts the direction of the valve guide 10 according to the detection information of the direction detection component 220 and the preset feeding direction, so that the valve guide 10 is adjusted to the preset feeding direction. Then, the valve guide 10 enters the feeding component 320. The preset feeding direction can be set to the end of the valve guide 10 with the annular groove 11 facing the inlet of the feeding assembly 320, or the end of the valve guide 10 away from the annular groove 11 facing the inlet of the feeding assembly 320. By using the valve guide directional conveying device provided by the technical solution, the direction of the valve guide 10 can be automatically detected to ensure the consistency of the feeding direction of the valve guide 10, thereby greatly improving the production efficiency.

[0022] Optionally, the guide platform 211 includes a bottom plate and side plates vertically connected to both sides of the bottom plate, and the movable slider 212 is located between the two side plates and can slide back and forth along the extension direction of the side plates. It can be understood that the bottom plate supports the movable slider 212, and the side plates guide the movable slider 212. Optionally, the shape of the positioning groove 212a is set according to the shape of the valve guide 10. Optionally, a guide tube position sensor 214 is provided on the guide platform 211, and the guide tube position sensor 214 is used to detect whether the valve guide 10 is delivered in place. When the guide tube position sensor 214 detects that the valve guide 10 enters the positioning groove 212a, the next step can be executed.

[0023] Further, see Figure 3 and Figure 4The direction detection component 220 includes an air pump (not shown in the figure), a pressure detection component 221, an air pipe 222 and a connecting component 223. The inlet end of the air pipe 222 is connected to the air pump. The pressure detection component 221 is arranged on the air pipe 222 for detecting the internal pressure of the air pipe 222. The connecting component 223 is connected to the outlet end of the air pipe 222. The connecting component 223 has a connecting port connected to the air pipe 222. A avoidance port is arranged on the top of the movable slider 212. The avoidance port is connected to the positioning groove 212a. The avoidance port and the end position of the valve guide 10 are opposite. The connecting component 223 can be pressed on the valve guide 10 through the avoidance port so that the connecting port fits the end side wall of the valve guide 10. The air pump is used to inflate the air pipe 222. The pressure detection component 221 is used to detect the internal pressure of the air pipe 222.

[0024] It can be understood that, since one end of the valve guide 10 has an annular groove 11, when the communication port is fitted to the annular groove 11 of the valve guide 10, the gas can flow through the annular groove 11, and when the communication port of the trachea 222 is fitted to the end of the valve guide 10 without the annular groove 11, the communication port is blocked, and accordingly, the gas pressure inside the trachea 222 is greater. Optionally, the end surface of the connector 223 in contact with the valve guide 10 is an arc surface, so that it can better fit the valve guide 10. Optionally, the connector 223 is connected to the valve guide 10 by bonding or threading.

[0025] Optionally, the number of avoidance openings on the movable slider 212 is two, that is, the avoidance openings include a first avoidance opening 212b and a second avoidance opening 212c, and accordingly, the guide tube includes a first air pipe 222a and a second air pipe 222b, the first avoidance opening 212b and the first air pipe 222a are correspondingly arranged, and the second avoidance opening 212c and the second air pipe 222b are correspondingly arranged. During operation, by inflating the first air pipe 222a and the second air pipe 222b, the air pressure inside the two air pipes 222 can be compared, and the side with smaller air pressure is the end of the valve guide tube 10 where the annular groove 11 is arranged, and the side with larger air pressure is the end of the valve guide tube 10 where the annular groove 11 is not arranged.

[0026] Furthermore, the direction detection component 220 also includes a lifting plate 226 and a lifting drive 227. One end of the air pipe 222 connected to the connecting member 223 is passed through the lifting plate 226. The lifting drive 227 is used to drive the lifting plate 226 to move in the vertical direction so that the connecting member 223 is pressed against the valve guide 10.

[0027] It can be understood that after the valve guide 10 enters the positioning groove 212a, the lifting drive 227 drives the lifting plate 226 to descend, so that the lifting plate 226 drives one end of the trachea 222 connected to the connecting member 223 to descend, until the communication port on the connecting member 223 fits the valve guide 10 through the avoidance port. After the detection is completed, the lifting drive 227 drives the lifting plate 226 to rise, so that the lifting plate 226 drives one end of the trachea 222 connected to the connecting member 223 to rise, so that the connecting member 223 is away from the valve guide 10. Optionally, the lifting drive 227 can be a cylinder. Optionally, a connecting plate is connected to the fixed end of the cylinder, and an upper position sensor 228 and a lower position sensor 229 are arranged on the connecting plate. The upper position sensor 228 is used to detect whether the lifting plate 226 returns to the initial position, and the lower position sensor 229 is used to detect whether the lifting plate 226 reaches the position where the connecting member 223 presses the valve guide 10.

[0028] Furthermore, one end of the air pipe 222 connected to the connecting piece 223 is movably inserted into the lifting plate 226, and a spring 224 and a limit piece 225 are sleeved on the air pipe 222. The spring 224 is located between the lifting plate 226 and the connecting piece 223, and the side of the lifting plate 226 facing away from the spring 224 abuts against the limit piece 225.

[0029] By sleeve-arranging the spring 224 and the stopper 225 on the air pipe 222, when the lifting plate 226 moves downward, the connecting member 223 presses on the valve guide 10, the stopper 225 moves upward with the valve guide 10, and the spring 224 contracts, so that the connecting member 223 is stably pressed on the valve guide 10; after detecting the direction of the valve guide 10, the lifting plate 226 moves upward, the connecting member 223 moves away from the valve guide 10, and at the same time, the restoring force of the spring 224 itself causes the valve guide 10 to move downward until the stopper 225 abuts against the lifting plate 226. By arranging the spring 224 on the air pipe 222, a buffering effect can be achieved.

[0030] Further, Figure 5 Schematically shows a structural diagram of the direction detection device 200 according to an embodiment of the present invention at another viewing angle. Figure 5 The direction detection device 200 also includes a recovery component 230, which is arranged at the bottom of the guide platform 211. A first discharge port 211b facing the recovery component 230 is opened on the guide platform 211. By moving the slider 212 along the guide platform 211, the bottom of the positioning groove 212a can be connected to the first discharge port 211b.

[0031] When the gas pressure inside the two air pipes 222 is low, it means that both ends of the valve guide 10 are leaking, the valve guide 10 is unqualified, and the directionality of the valve guide 10 cannot be determined. At this time, the slider cylinder drives the movable slider 212 to move to the position facing the first discharge port 211b, and the valve guide 10 falls into the guide groove 231 through the first discharge port 211b, and then falls into the discharge barrel 232 through the second discharge port 231a. Optionally, the recovery component 230 includes a guide groove 231 and a discharge barrel 232, the guide groove 231 is provided with a second discharge port 231a, the guide groove 231 is arranged at the bottom of the guide platform 211, and the discharge barrel 232 is arranged at the bottom of the guide groove 231. Optionally, the bottom of the guide groove 231 includes an inclined plate and a horizontal plate, and the second discharge port 231a is arranged on the horizontal plate. The valve guide 10 can fall from the first discharge port 211b onto the inclined plate, and then slide from the inclined plate to the second discharge port 231a. Optionally, the discharge barrel 232 is funnel-shaped.

[0032] Further, Figure 6 The schematic diagram of the structure of the slider driving member 213 according to the embodiment of the present invention is shown schematically. Figure 6 A slider position sensor 2132 is provided on the slider driving member 213 . The slider driving member 213 is a cylinder. The piston rod 2131 of the cylinder is connected to the movable slider 212 . The slider position sensor 2132 is used to detect the position of the piston rod 2131 .

[0033] The movable slider 212 can stay at three positions on the guide platform 211. The first position is the position where the positioning groove 212a on the movable slider 212 is connected to the loading device 100, the second position is the position where the positioning groove 212a is connected to the flip feeding device 300, and the third position is the position where the positioning groove 212a is connected to the first discharge port 211b. Therefore, three slider position sensors 2132 can be set on the cylinder so that the piston rod 2131 can stay at the above three positions.

[0034] Further, Figure 7 The schematic diagram of the structure of the feeding device 100 according to the embodiment of the present invention is shown schematically. Figure 7 The feeding device 100 includes a vibrating screen 110 and a feeding guide rail 120. The vibrating screen 110 includes a barrel-shaped shell 111, a spiral table 112 and a vibration component. The spiral table 112 is arranged inside the shell 111, and the vibration component is arranged at the bottom of the shell 111. The feeding guide rail 120 is used to connect the spiral table 112 and the valve guide inlet. The vibration component is used to vibrate the spiral table 112. Through the vibration of the spiral table 112, the valve guide 10 can be transported along the table surface of the spiral table 112 to the feeding guide rail 120.

[0035] Through the vibration of the vibration component, the valve guide 10 can move upward in a spiral on the spiral platform 112, so that the valve guides 10 are transported to the feed guide rail 120 one by one, and then enter the positioning groove 212a along the feed guide rail 120. Optionally, the feed guide rail 120 is a long rail structure. In order to facilitate the valve guide 10 to enter the positioning groove 212a, the feed guide rail 120 can be tilted so that the end of the feed guide rail 120 connected to the vibrating screen 110 is higher than the end of the feed guide rail 120 connected to the positioning groove 212a. Optionally, the vibration component includes a vibrator and an exciter, the vibrator is arranged inside the exciter, and the exciter generates vibration by driving the vibrator, thereby causing the spiral platform 112 to vibrate.

[0036] Optionally, the loading device 100 further includes a loading hopper 130, which includes a funnel-shaped channel with a top opening and a bottom opening and a guide plate connected to the bottom of the funnel-shaped channel. When the valve guide 10 needs to be added, the valve guide 10 is put in from the top of the loading hopper 130, and then the valve guide 10 can fall to the guide plate and then fall into the vibrating screen 110.

[0037] Further, Figure 8 The structure diagram of the overturning feeding device 300 according to the embodiment of the present invention is schematically shown. Figure 8 The flip assembly 310 includes a flip plate 311 and a flip driving member 312. A drop opening 311a is provided in the middle of the flip plate 311. The flip plate 311 can move relative to the outlet end of the guide platform 211. The moving direction of the flip plate 311 is the axial direction of the valve guide 10. The frame of the flip plate 311 along the width direction is used to contact the end of the valve guide 10 to rotate the valve guide 10. After the valve guide 10 rotates, it can fall from the drop opening 311a. The flip driving member 312 is configured to drive the flip plate 311 to move according to the direction of the valve guide 10 on the guide platform 211.

[0038] In this embodiment, the axial direction of the valve guide 10 in the positioning groove 212a is perpendicular to the moving direction of the valve guide 10 on the guide platform 211, so the flip plate 311 moves relative to the axial direction of the valve guide 10. Optionally, the flip driving member 312 can be a cylinder. Exemplarily, according to the detection information of the direction detection component 220, when the valve guide 10 needs to rotate counterclockwise, the cylinder pushes the flip plate 311 away from the fixed end of the cylinder, so that the end of the valve guide 10 contacts the second frame 311c of the flip plate 311, and the valve guide 10 rotates counterclockwise; when the valve guide 10 needs to rotate clockwise, the cylinder pushes the flip plate 311 close to the fixed end of the cylinder, so that the end of the valve guide 10 contacts the first frame 311b of the flip plate 311, and the valve guide 10 rotates clockwise. It can be understood that the direction of the valve guide 10 after rotation should be consistent.

[0039] Further, see Figure 8 The feed assembly 320 includes a material trough 321, a check pipe 322 and a check drive 323. The material trough 321 has a funnel-shaped communication channel. The material trough 321 is arranged at the bottom of the flip plate 311. The check pipe 322 is arranged at the bottom of the material trough 321. The top of the communication channel is connected to the drop port 311a. The bottom of the communication channel is connected to the check pipe 322. After the valve guide 10 drops from the drop port 311a, it enters the check pipe 322 through the communication channel. The check drive 323 is used to drive the check pipe 322 to move to a specified position. It can be understood that the moving distance of the flip plate 311 needs to be set according to the specific length of the valve guide 10 to ensure that the valve guide 10 can rotate as required.

[0040] In one embodiment, the top of the communication channel is a rectangular opening, and the cross-sectional area gradually decreases from the top to the bottom. Optionally, the bottom of the communication channel is connected to a cylindrical channel, and when the valve guide 10 falls, it enters the cylindrical channel from the communication cavity. Optionally, a connecting channel 324 is provided between the trough 321 and the check tube 322, and the front of the connecting channel 324 is open, so that the falling process of the valve guide 10 can be observed through the connecting channel 324 to ensure the direction consistency of the valve guide 10. Optionally, the check drive 323 is located on the side of the check tube 322, and after the valve guide 10 falls into the check tube 322, the check drive 323 can drive the check tube 322 to move to the next station for assembly. In order to ensure that the check drive 323 can push the check tube 322 to a preset position, a position sensor can be provided on the check drive 323. Optionally, the check drive 323 can be a cylinder or a motor.

[0041] Optionally, the valve guide 10 positioning and conveying device further comprises a control unit, and each sensor and driving member are connected to the control unit by signal. The main function of the control unit is to receive and process input signals and send control signals.

[0042] The following takes the feeding direction as an example that the end of the valve guide 10 away from the annular groove 11 is toward the entrance of the material groove 321 to illustrate the working process of the valve guide directional conveying device in the present technical solution: The valve guide 10 falls from the loading funnel 130 into the vibrating screen 110, and the valve guide 10 gradually moves along the spiral table 112 toward the feed guide rail 120 due to the vibration of the vibrating screen 110. Then, the valve guide 10 enters the positioning groove 212a through the feed guide rail 120 and the connecting hole 211a. When the two ends of the valve guide 10 are respectively opposite to the first avoidance port 212b and the second avoidance port 212c, the valve guide 10 moves into position, and then the guide position sensor 214 transmits a signal to the control unit.

[0043] After receiving the signal from the guide tube position sensor 214, the control unit controls the lifting drive 227 to start. Then, the lifting drive 227 drives the lifting plate 226 to move downward until the connecting member 223 presses on the valve guide tube 10. At this time, the spring 224 on the air pipe 222 contracts, and the stopper 225 moves away from the upper end surface of the lifting plate 226. When the lower position sensor 229 detects that the lifting plate 226 has fallen into place, it sends a signal to the control unit.

[0044] Further, the control unit controls the air pump to turn on, and the air pump inflates the two ends of the valve guide 10 through the first air pipe 222a and the second air pipe 222b. The pressure detection member 221 performs pressure detection. When the air pressure of the first air pipe 222a is less than that of the second air pipe 222b, it indicates that the annular groove 11 is located at the first avoidance port 212b; when the air pressure of the first air pipe 222a is less than that of the second air pipe 222b, it indicates that the annular groove 11 is located at the second avoidance port 212c; when the air pressure of the first air pipe 222a and the second air pipe 222b are both small, it indicates that the first avoidance port 212b and the second avoidance port 212c are both leaking, the valve guide 10 is unqualified, and the directionality of the valve guide 10 cannot be determined.

[0045] After completing the step of detecting the direction of the valve guide 10, the control unit controls the lifting drive 227 to start, so that the lifting plate 226 moves upward. At this time, the connecting member 223 is away from the trachea 222 guide tube, the spring 224 extends by its own restoring force, and the limiter 225 abuts against the lifting plate 226. After the lifting plate 226 rises to the preset position, the lower position sensor 229 sends a signal to the control unit, and then the lifting drive 227 stops.

[0046] When the lifting plate 226 rises, the control unit controls the slider driver 213 to start. When both the first avoidance port 212b and the second avoidance port 212c are leaking, the slider driver 213 drives the movable slider 212 to move toward the rear of the guide platform 211, so that the positioning groove 212a faces the first discharge port 211b, and the unqualified valve guide 10 can fall into the discharge barrel 232 through the first discharge port 211b and the second discharge port 231a. When the annular groove 11 is located at the first avoidance opening 212b, the slider driving member 213 drives the movable slider 212 to move toward the front of the guide platform 211, and at the same time, the flip driving member 312 drives the flip plate 311 to move toward the fixed end of the flip driving member 312, so that the first frame 311b contacts the end of the valve guide 10 provided with the annular groove 11, so that the end of the valve guide 10 away from the annular groove 11 falls into the material trough 321 toward the entrance of the material trough 321; when the annular groove 11 is located at the second avoidance opening 212c, the slider driving member 213 drives the movable slider 212 to move toward the front of the guide platform 211, and at the same time, the flip driving member 312 drives the flip plate 311 to move toward the fixed end of the flip driving member 312, so that the second frame 311c contacts the end of the valve guide 10 provided with the annular groove 11, so that the end of the valve guide 10 away from the annular groove 11 falls into the material trough 321 toward the entrance of the material trough 321.

[0047] The valve guide 10 enters the connecting channel 324 through the material slot 321 and then falls into the check tube 322. After the valve guide 10 falls into the check tube 322, the check drive 323 drives the check tube 322 to move, so that the check tube 322 moves to a preset position.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
