Description

Technical Field

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

[0002] The valve guide of the engine cylinder head guides the valve, ensures that the valve makes a reciprocating linear motion, enables the valve and the valve seat ring to be correctly fitted, and transfers the heat of the valve stem to the cylinder head. Refer to Figure 1 , some valve guides have annular grooves machined on the outer cylindrical surface. During assembly, the annular grooves are inserted into the intake and exhaust valve stem seals to fasten the lower seat of the valve spring to prevent loosening. Due to the existence of the annular grooves, it is necessary to judge the directionality when installing the valve guide. However, at present, the automatic detection of the directionality of the cylinder head valve guide has not been realized, which is very inconvenient in the case of a large number of processed parts.

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

[0004] The purpose of the present invention is to at least solve the problem of how to judge and adjust the direction of the valve guide as needed. This purpose is achieved through the following technical solutions:

[0005] The first aspect of the present invention proposes a valve guide directional conveying device, including a feeding device, a direction detection device, and a flipping and feeding device;

[0006] The direction detection device includes a platform assembly and a direction detection assembly, and the flipping and feeding device includes a flipping assembly and a feeding assembly;

[0007] The feeding device is used to convey the valve guide to the platform assembly, the direction detection assembly is used to judge the direction of the valve guide on the platform assembly, the platform assembly can convey the valve guide to the flipping assembly according to the detection information of the direction detection assembly, the flipping assembly is set to adjust the direction of the valve guide according to the preset feeding direction and the detection information of the direction detection assembly, and the feeding assembly is used to receive the valve guide whose direction has been adjusted by the flipping assembly;

[0008] The platform component includes a guiding platform, a moving slider, and a slider driving member. The outlet end of the guiding platform faces the flipping component. The moving slider is arranged on the guiding platform. The slider driving member is used to drive the moving slider to move along the guiding platform. The moving slider has a positioning groove with an open bottom. The side surface of the moving slider has an air valve conduit inlet, and the air valve conduit inlet communicates with the positioning groove. The air valve conduit can be inserted into the positioning groove through the air valve conduit inlet. By moving the moving slider along the guiding platform, the open bottom of the positioning groove can be made to face the flipping component.

[0009] During the use of the air valve conduit directional conveying device provided by this technical solution, the air valve conduit is conveyed into the positioning groove of the moving slider by the feeding device, and the guiding platform plays a supporting role for the moving slider and the air valve conduit. The direction of the air valve conduit in the moving slider is random. At this time, the direction detection component judges the direction of the air valve conduit. Subsequently, the slider driving member drives the moving slider to move along the guiding platform. After the positioning groove moves out of the guiding platform, the air valve conduit drops from the open bottom of the positioning groove to the flipping component. Furthermore, the flipping component adjusts the direction of the air valve conduit according to the preset feeding direction and the detection information of the direction detection component, so that the feeding direction of the air valve conduit is adjusted to the preset feeding direction. Then, the air valve conduit enters the feeding component. The preset feeding direction can be set such that the end of the air valve conduit provided with the annular groove faces the inlet of the feeding component, or the end of the air valve conduit away from the annular groove faces the inlet of the feeding component. By using the air valve conduit directional conveying device provided by this technical solution, not only can the direction of the air valve conduit be automatically detected, but also the consistency of the feeding direction of the air valve conduit can be ensured, greatly improving the production efficiency.

[0037] Figure 1 The structural schematic diagram of the valve guide 10 in the prior art is schematically shown. Figure 2 The structural schematic diagram of the valve guide directional conveying device according to an embodiment of the present invention is schematically shown. Figure 3 The structural schematic diagram of the direction detection device 200 according to an embodiment of the present invention at a certain perspective is schematically shown. Figure 4 The structural schematic diagram of the moving slider 212 according to an embodiment of the present invention is schematically shown. Refer to Figures 1 to 4The 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 It is 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 driver 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, and the slider driver 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, and the side of the movable slider 212 has a valve guide inlet, and the valve guide inlet is connected to the positioning groove 212a. 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.

[0038] During the use of the valve guide directional conveying device provided by the technical solution, the valve guide 10 is conveyed to the positioning groove 212a of the moving slider 212 by 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, and 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.

[0039] Optionally, the guiding platform 211 includes a bottom plate and side plates vertically connected to both sides of the bottom plate. The moving slider 212 is located between the two side plates and can reciprocate along the extending direction of the side plates. Understandably, the bottom plate supports the moving slider 212, and the side plates guide the moving slider 212. Optionally, the shape of the positioning groove 212a is set according to the shape of the valve guide 10. Optionally, a conduit position sensor 214 is provided on the guiding platform 211. The conduit position sensor 214 is used to detect whether the valve guide 10 is delivered in place. When the conduit position sensor 214 detects that the valve guide 10 enters the positioning groove 212a, the next step can be executed.

[0040] Further, continue to refer to Figure 3 and Figure 4 , the direction detection assembly 220 includes an air inflation pump (not shown in the figure), a pressure detection member 221, an air pipe 222, and a connecting member 223. The inlet end of the air pipe 222 is communicated with the air inflation pump. The pressure detection member 221 is arranged on the air pipe 222 and is used to detect the internal pressure of the air pipe 222. The connecting member 223 is connected to the outlet end of the air pipe 222. The connecting member 223 has a communication port communicated with the air pipe 222. An avoidance port is arranged at the top of the moving slider 212. The avoidance port is communicated with the positioning groove 212a. The avoidance port is opposite to the end position of the valve guide 10. The connecting member 223 can be pressed against the valve guide 10 through the avoidance port so that the communication port fits against the end side wall of the valve guide 10. The air inflation pump is used to inflate the air pipe 222, and the pressure detection member 221 is used to detect the internal pressure of the air pipe 222.

[0041] Understandably, since one end of the valve guide 10 has an annular groove 11, when the communication port fits against the annular groove 11 of the valve guide 10, gas can flow through the annular groove 11. When the communication port of the air pipe 222 fits against the end of the valve guide 10 without the annular groove 11, the communication port is blocked. Correspondingly, the gas pressure inside the air pipe 222 is greater. Optionally, the end face of the connecting member 223 in contact with the valve guide 10 is an arc surface, so that it can better fit against the valve guide 10. Optionally, the connecting member 223 is connected to the valve guide 10 by means of adhesion or threaded connection.

[0042] 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. Correspondingly, the conduit includes a first air pipe 222a and a second air pipe 222b. The first avoidance opening 212b is correspondingly arranged with the first air pipe 222a, and the second avoidance opening 212c is correspondingly arranged with the second air pipe 222b. 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. The side with lower air pressure is the end of the valve conduit 10 where the annular groove 11 is arranged, and the side with higher air pressure is the end of the valve conduit 10 where the annular groove 11 is not arranged.

[0043] 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 inserted into 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.

[0044] 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 the end of the air pipe 222 connected to the connecting member 223 to descend, until the connecting 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 the end of the air pipe 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 provided 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.

[0045] Furthermore, one end of the air pipe 222 connected to the connecting piece 223 is movably arranged on the lifting plate 226, and a spring 224 and a stopper 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 stopper 225.

[0046] By sleeving a spring 224 and a limiting member 225 on the air pipe 222, after the lifting plate 226 moves downward, the connecting member 223 presses on the valve guide 10, the limiting member 225 moves upward along with the valve guide 10, and at the same time the spring 224 contracts, so that the connecting member 223 stably presses 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 limiting member 225 abuts against the lifting plate 226. By arranging the spring 224 on the air pipe 222, a buffering effect can be achieved.

[0047] Further, Figure 5 Schematically shows a schematic structural diagram of the direction detection device 200 according to an embodiment of the present invention from another perspective. Refer to Figure 5 , the direction detection device 200 further includes a recovery assembly 230, the recovery assembly 230 is arranged at the bottom of the guiding platform 211, a first discharge port 211b facing the recovery assembly 230 is formed on the guiding platform 211, and by moving the sliding block 212 along the guiding platform 211, the bottom of the positioning groove 212a can be communicated with the first discharge port 211b.

[0048] When the gas pressures inside the two air pipes 222 are both low, it indicates that both ends of the valve guide 10 are leaking air, the valve guide 10 is unqualified, and the directionality of the valve guide 10 cannot be judged. At this time, the slider cylinder drives the moving slider 212 to move to a position facing the first discharge port 211b, and the valve guide 10 falls into the material guiding groove 231 through the first discharge port 211b, and then falls into the discharge bucket 232 through the second discharge port 231a. Optionally, the recovery assembly 230 includes a material guiding groove 231 and a discharge bucket 232, a second discharge port 231a is arranged on the material guiding groove 231, the material guiding groove 231 is arranged at the bottom of the guiding platform 211, and the discharge bucket 232 is arranged at the bottom of the material guiding groove 231. Optionally, the bottom of the material guiding 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 bucket 232 is funnel-shaped.

[0049] Further, Figure 6 Schematically shows a schematic structural diagram of the slider driving member 213 according to an embodiment of the present invention. Refer to Figure 6 , a slider position sensor 2132 is arranged 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 moving slider 212, and the slider position sensor 2132 is used to detect the position of the piston rod 2131.

[0050] The movable slider 212 can stay at three positions on the guiding platform 211. The first position is the position where the positioning groove 212a on the movable slider 212 communicates with the feeding device 100, the second position is the position where the positioning groove 212a communicates with the flipping feeding device 300, and the third position is the position where the positioning groove 212a communicates with the first discharge port 211b. Therefore, three slider position sensors 2132 can be arranged on the air cylinder, so that the piston rod 2131 can stay at the above three positions.

[0051] Furthermore, Figure 7 Schematically shown is a structural schematic diagram of the feeding device 100 according to an embodiment of the present invention. Refer to 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 housing 111, a spiral platform 112 and a vibrating member. The spiral platform 112 is arranged inside the housing 111, and the vibrating member is arranged at the bottom of the housing 111. The feeding guide rail 120 is used to connect the spiral platform 112 and the valve guide inlet. The vibrating member is used to vibrate the spiral platform 112. Through the vibration of the spiral platform 112, the valve guide 10 can be conveyed to the feeding guide rail 120 along the tabletop of the spiral platform 112.

[0052] Through the vibration of the vibrating member, the valve guide 10 can move spirally upward on the spiral platform 112, so that the valve guides 10 are conveyed to the feeding guide rail 120 one by one. Subsequently, they enter the positioning groove 212a along the feeding guide rail 120. Optionally, the feeding guide rail 120 is a long strip-shaped track structure. To facilitate the valve guide 10 to enter the positioning groove 212a, the feeding guide rail 120 can be inclined so that the end of the feeding guide rail 120 connected to the vibrating screen 110 is higher than the end of the feeding guide rail 120 connected to the positioning groove 212a. Optionally, the vibrating member includes a vibrator and an exciting vibrator. The vibrator is arranged inside the exciting vibrator, and the exciting vibrator generates vibration by driving the vibrator, so as to vibrate the spiral platform 112.

[0053] Optionally, the feeding device 100 further includes a feeding funnel 130. The feeding funnel 130 includes a funnel-shaped channel with a top opening and a bottom opening and a guiding plate connected to the bottom of the funnel-shaped channel. When it is necessary to add the valve guide 10, the valve guide 10 is put in from the top of the feeding funnel 130, and then the valve guide 10 can fall onto the guiding plate and then into the vibrating screen 110.

[0054] Furthermore, Figure 8 Schematically shown is a structural schematic diagram of the flipping feeding device 300 according to an embodiment of the present invention. Refer to Figure 8, the flipping assembly 310 includes a flipping plate 311 and a flipping driving member 312. A dropping opening 311a is provided in the middle of the flipping plate 311. The flipping plate 311 is capable of moving relative to the outlet end of the guiding platform 211. The moving direction of the flipping plate 311 is the axial direction of the valve guide 10. The border of the flipping plate 311 in the width direction is used to contact the end of the valve guide 10 so as to rotate the valve guide 10. After the valve guide 10 rotates, it can drop from the dropping opening 311a. The flipping driving member 312 is arranged to drive the flipping plate 311 to move according to the direction of the valve guide 10 on the guiding platform 211.

[0055] 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 guiding platform 211. Therefore, the flipping plate 311 moves relative to the axial direction of the valve guide 10. Optionally, the flipping driving member 312 can be a cylinder. Exemplarily, according to the detection information of the direction detection assembly 220, when the valve guide 10 needs to rotate counterclockwise, the cylinder pushes the flipping plate 311 away from the fixed end of the cylinder, so that the end of the valve guide 10 contacts the second border 311c of the flipping plate 311, realizing the counterclockwise rotation of the valve guide 10; when the valve guide 10 needs to rotate clockwise, the cylinder pushes the flipping plate 311 close to the fixed end of the cylinder, so that the end of the valve guide 10 contacts the first border 311b of the flipping plate 311, realizing the clockwise rotation of the valve guide 10. It can be understood that the consistency of the direction of the valve guide 10 after rotation should be ensured.

[0056] Further, continue to refer to Figure 8 , the feeding assembly 320 includes a material trough 321, a check valve pipe 322 and a check valve driving member 323. The material trough 321 has a funnel-shaped communication channel. The material trough 321 is arranged at the bottom of the flipping plate 311. The check valve pipe 322 is arranged at the bottom of the material trough 321. The top of the communication channel is communicated with the dropping opening 311a, and the bottom of the communication channel is communicated with the check valve pipe 322. The valve guide 10 drops from the dropping opening 311a and enters the check valve pipe 322 through the communication channel. The check valve driving member 323 is used to drive the check valve pipe 322 to move to a specified position. It can be understood that the moving distance of the flipping 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.

[0057] 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, a cylindrical channel is connected to the bottom of the communication channel. When the valve guide 10 falls, it enters the cylindrical channel from the communication cavity. Optionally, a connection channel 324 is provided between the feed trough 321 and the check valve pipe 322. The front of the connection channel 324 is open, so that the falling process of the valve guide 10 can be observed through the connection channel 324 to ensure the direction consistency of the valve guide 10. Optionally, the check valve driving member 323 is located on the side of the check valve pipe 322. After the valve guide 10 falls into the check valve pipe 322, the check valve driving member 323 can drive the check valve pipe 322 to move to the next working station for assembly. To ensure that the check valve driving member 323 can push the check valve pipe 322 to the preset position, a position sensor can be provided on the check valve driving member 323. Optionally, the check valve driving member 323 can be a cylinder or a motor.

[0058] Optionally, the valve guide 10 positioning and conveying device further includes a control unit, and each sensor and driving member are signal-connected to the control unit. The main function of the control unit is to receive and process input signals and send control signals, etc.

[0059] Taking the feeding direction as an example where one end of the valve guide 10 away from the annular groove 11 faces the inlet of the feed trough 321, the working process of the valve guide orientation conveying device in the present technical solution will be described as follows:

[0060] The valve guide 10 falls from the feeding hopper 130 into the vibrating screen 110. The valve guide 10 gradually moves along the spiral platform 112 towards the conveying guide rail 120 through the vibration of the vibrating screen 110. Furthermore, the valve guide 10 enters the positioning groove 212a through the conveying guide rail 120 and the communication 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 place, and then the conduit position sensor 214 sends a signal to the control unit.

[0061] After the control unit receives the signal from the conduit position sensor 214, it controls the lifting driving member 227 to start. Furthermore, the lifting driving member 227 drives the lifting plate 226 to move downward until the connecting member 223 presses on the valve guide 10. At this time, the spring 224 on the air pipe 222 contracts, and the limiting member 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 descended in place, it sends a signal to the control unit.

[0062] Further, the control unit controls the inflation pump to turn on, and the inflation pump inflates both ends of the valve guide 10 through the first air pipe 222a and the second air pipe 222b respectively. The pressure detection member 221 performs pressure detection. When the air pressure in the first air pipe 222a is less than that in the second air pipe 222b, it indicates that the annular groove 11 is located at the first avoidance port 212b; when the air pressure in the first air pipe 222a is less than that in the second air pipe 222b, it indicates that the annular groove 11 is located at the second avoidance port 212c; when the air pressures in both the first air pipe 222a and the second air pipe 222b are relatively small, it indicates that both the first avoidance port 212b and the second avoidance port 212c are leaking air, and the valve guide 10 is unqualified, and the directionality of the valve guide 10 cannot be judged.

[0063] After completing the step of detecting the direction of the valve guide 10, the control unit controls the lifting drive member 227 to start, causing the lifting plate 226 to move upward. At this time, the connecting member 223 moves away from the air pipe 222 conduit, and the spring 224 elongates by its own restoring force, and the limiting member 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 member 227 stops.

[0064] While the lifting plate 226 is rising, the control unit controls the slider drive member 213 to start. When both the first avoidance port 212b and the second avoidance port 212c are leaking air, the slider drive member 213 drives the moving slider 212 to move backward to the rear of the guiding platform 211, making the positioning groove 212a face the first discharge port 211b, so that the unqualified valve guide 10 can fall into the discharge bucket 232 through the first discharge port 211b and the second discharge port 231a. When the annular groove 11 is located at the first avoidance port 212b, the slider drive member 213 drives the moving slider 212 to move forward to the front of the guiding platform 211. At the same time, the flipping drive member 312 drives the flipping plate 311 to move in the direction close to the fixed end of the flipping drive member 312, making the first frame 311b contact 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 port 212c, the slider drive member 213 drives the moving slider 212 to move forward to the front of the guiding platform 211. At the same time, the flipping drive member 312 drives the flipping plate 311 to move in the direction away from the fixed end of the flipping drive member 312, making the second frame 311c contact 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.

[0065] The valve guide 10 enters the connection channel 324 through the chute 321 and then drops into the check pipe 322. After the valve guide 10 drops into the check pipe 322, the check driving member 323 drives the check pipe 322 to move, so that the check pipe 322 moves to a preset position.

[0066] As mentioned above, it 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 those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
