Description

Technical Field

[0001] This invention relates to the field of conveying mechanism technology, specifically to a self-air-cooled vertical conveying mechanism for engine cylinder heads. Background Technology

[0002] The engine cylinder head is a core sealing component installed on top of the cylinder block. It is tightly connected to the cylinder block with bolts to prevent cylinder leakage, enabling the engine to be used well in automobiles and other fields. After the engine cylinder head is cast, it needs to be transported to a designated station by a conveyor mechanism for further processing such as cylinder head vibration, sawing risers, surface grinding, and polishing, so that the engine cylinder head meets the requirements of subsequent use. For example, the patent application with publication number "CN120135693A" entitled "A Plate Chain Conveying Device" discloses that when conveying a single piece of rolled steel, the output end of the cylinder is in the extended state, and the lifting slide drives the rotating shaft and the first actuating wheel to rise synchronously until the first actuating rod is inserted into the teeth of the first actuating wheel. While pushing the transmission chain plate to a horizontal state, it can maintain the stable conveying of each transmission chain plate. When conveying bundled finished steel products, the output end of the cylinder is in the retracted state, the lifting slide is placed at the lowest point, and the actuating wheel... One disengages from the lever and engages with the transmission gear, driving the shaft to rotate via the drive motor. This, in turn, drives the transmission gear to rotate via the first actuating wheel. Under the combined action of the limiting arm and the sliding of the rolling seat in the guide rail, the second actuating wheel, which is offset from the first actuating wheel, will flip until the second lever is inserted into the teeth of the second actuating wheel. This pushes the transmission chain plate into a flipped state, quickly raising the joint binding position with height differences, reducing the impact intensity on the overall transmission chain plate. Furthermore, the relative stillness between each transmission chain plate allows for a smoother transition to each set of transmission chain plates, reducing the failure rate.

[0003] The existing conveying mechanisms described above consist of only a set of transmission chain plates, which can only convey materials in one direction. When workpieces need to be conveyed to different processing stations, the placement and orientation of these stations are different, which means that the existing conveying mechanisms cannot meet the different conveying requirements and thus cannot achieve unmanned automatic transfer operations. Furthermore, the existing conveying mechanisms have relatively simple structures and functions and cannot perform automatic air cooling of the conveyed materials. Therefore, we propose an engine cylinder head self-air-cooled vertical conveying mechanism to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide an engine cylinder head self-air-cooled vertical conveying mechanism to solve the problems mentioned in the background art. The existing conveying mechanisms are composed of only a set of transmission chain plates, which can only convey materials in one direction. When it is necessary to convey workpieces to different processing stations, the placement position and orientation of the different processing stations are different, which makes the existing conveying mechanisms unable to meet different conveying needs and thus unable to achieve unmanned automatic transfer operations. Moreover, the existing conveying mechanisms have relatively simple structures and functions and cannot perform automatic air-cooling operations on the conveyed materials.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an engine cylinder head self-air-cooled vertical conveying mechanism, comprising a first lifting mechanism and air-cooled conveying chain plates disposed on the left and right sides below it. Rotating chain plates are disposed at the front and rear sides of the air-cooled conveying chain plates. An overhead chain plate conveying platform is connected to the upper right side of the first lifting mechanism, and a second lifting mechanism is connected to the right side of the overhead chain plate conveying platform. A cylinder head lifting platform is installed on the front side of both the first and second lifting mechanisms. Rotating transition chain plates are disposed on the left and right sides of the cylinder head lifting platform, and a rotating chain plate for adjusting the conveying direction of the engine cylinder head is disposed on the side of the rotating transition chain plate away from the cylinder head lifting platform. A self-air-cooling mechanism is installed above the air-cooled conveying chain plates and the overhead chain plate conveying platform.

[0006] Preferably, the cylinder head lifting platform is equipped with a chain conveyor mechanism.

[0007] The above structure enables the chain conveyor to transport the engine cylinder head from above to the overhead chain conveyor platform.

[0008] Preferably, two rotating shafts are symmetrically installed on the upper interior of both the first and second lifting mechanisms. A motor is installed at one end of each rotating shaft via a coupling. A chain is meshed with the outer side of a gear installed on the outer side of the rotating shaft. A lifting basket is installed at the front end of the chain. A cylinder head lifting platform is fixed to the front side of the lifting basket. A counterweight is installed at the rear end of the chain.

[0009] The above structure allows the counterweight to apply downward pressure to the chain, ensuring stable meshing between the chain and the gear mounted on the outside of the shaft, thereby ensuring stable lifting operations of both the first and second lifting mechanisms.

[0010] Preferably, buffer pads are installed inside the bottom end of the counterweight balance block and the bottom end of the first lifting mechanism.

[0011] With the above structure, the buffer pad can prevent the bottom surface of the counterweight block from generating a large impact force with the bottom end of the first lifting mechanism.

[0012] Preferably, the structure of the first lifting mechanism is the same as that of the second lifting mechanism, and both the first and second lifting mechanisms are equipped with a fixing rod on the side near the overhead chain conveyor platform, and the other end of the fixing rod is connected to the overhead chain conveyor platform.

[0013] With the above-mentioned structure, the first and second lifting mechanisms are well integrated with the overhead chain conveyor platform, ensuring stability during transport.

[0014] Preferably, guardrails are installed above and below the first and second lifting mechanisms, as well as on the outer side of the overhead chain conveyor platform.

[0015] With the above structure, the guardrail can protect the upper outer side and lower outer side of the first and second lifting mechanisms, as well as the upper outer side of the overhead chain conveyor platform, to prevent the engine cylinder head from falling off in the event of an accident.

[0016] Preferably, the self-cooling mechanism includes a protective cover installed above the air-cooled conveyor chain and the overhead conveyor platform, and a cooling fan is installed through the upper surface of the protective cover, with the cooling fan being inclined.

[0017] With the above-mentioned structure, the inclined cooling fan can effectively perform self-air cooling of the engine cylinder head on the air-cooled conveyor chain and the overhead conveyor platform.

[0018] Preferably, a support frame is fixed to the bottom surface of the rotating chain plate, and a support base plate is connected to the bottom surface of the support frame. A fixed base is rotatably mounted on the bottom surface of the support base plate, and a motor is installed through the bottom surface of the fixed base plate. The output end of the motor is connected to the bottom surface of the support base plate.

[0019] The above structure ensures that the supporting base plate can rotate stably.

[0020] Preferably, two guide rail assemblies are symmetrically installed on the upper surface of the support base plate, and the bottom surface of the support frame forms a sliding structure with the support base plate through the guide rail assemblies. An electric push rod is installed at the middle position of the upper surface of the support base plate, and the output end of the electric push rod is connected to the bottom surface of the support frame.

[0021] The above structure allows the support frame to slide stably in the horizontal direction on the support base plate.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the self-air-cooled vertical conveying mechanism for engine cylinder heads can meet the conveying requirements of different directions and heights, realize unmanned automatic transfer, and improve conveying efficiency. Its specific details are as follows: (1) By using the air-cooled conveyor chain plate and the cooling fan together, the cast engine cylinder head can be automatically air-cooled and conveyed. The rotating chain plate drives the engine cylinder head to rotate 90° together, which makes it easy to adjust the conveying direction of the engine cylinder head. The rotating chain plate can effectively convey the engine cylinder head to the rotating transition chain plate that is perpendicular to the air-cooled conveyor chain plate. The rotating transition chain plate conveys the engine cylinder head to the cylinder head lifting platform. Then, the first lifting mechanism drives the cylinder head lifting platform to rise, so that the engine cylinder head on the cylinder head lifting platform can be conveyed to the overhead chain plate conveying platform. Finally, the overhead chain plate conveying platform conveys the engine cylinder head to the second lifting mechanism, so that the second lifting mechanism can effectively convey the engine cylinder head downward to the designated work position. Therefore, the vertical conveying mechanism can meet the conveying needs of different directions and different height positions, realize unmanned automatic transfer, and improve the conveying efficiency.

[0023] (2) The motor passing through the bottom of the fixed base drives the support plate to rotate, thereby causing the fixed base to drive the support frame and the rotating chain plate to rotate. Therefore, it is easy to adjust the direction of the rotating chain plate to meet different conveying needs. (3) The support frame can be pushed horizontally on the support base plate by the electric push rod, thereby adjusting the distance between the rotated chain plate and the rotating transition chain plate after rotation, so as to avoid the distance between the rotated chain plate and the rotating transition chain plate being too large and affecting the stability of the transfer and transportation of the engine cylinder head.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-9 The present invention provides the following technical solution: Example 1: The engine cylinder head self-air-cooled vertical conveying mechanism in this example can meet the conveying requirements of different directions and heights, realize unmanned automatic transfer, and improve conveying efficiency. See attached diagram for the specific structure. Figures 1-8 As shown, a first lifting mechanism 4 and air-cooled conveyor chain plates 1 are arranged on the left and right sides below it. Rotating chain plates 7 are arranged at the front and rear of the air-cooled conveyor chain plates 1. An overhead chain plate conveyor platform 5 is connected to the upper right side of the first lifting mechanism 4, and a second lifting mechanism 6 is connected to the right side of the overhead chain plate conveyor platform 5. A cylinder head lifting platform 3 is installed in front of both the first lifting mechanism 4 and the second lifting mechanism 6. Rotating transition chain plates 2 are arranged on the left and right sides of the cylinder head lifting platform 3, and the side of the rotating transition chain plate 2 away from the cylinder head lifting platform 3 is provided with a function to adjust the conveying direction of the engine cylinder head. The adjustable rotating chain plate 7, the air-cooled conveyor chain plate 1, and the overhead chain plate conveyor platform 5 are all equipped with self-air-cooling mechanisms. The cylinder head lifting platform 3 is equipped with a chain plate conveyor mechanism 31. The first lifting mechanism 4 and the second lifting mechanism 6 are both symmetrically equipped with two rotating shafts 41. One end of the rotating shaft 41 is equipped with a motor through a coupling. The outer side of the gear installed on the outer side of the rotating shaft 41 is meshed with a chain 42. The front end of the chain 42 is equipped with a lifting basket 44. The cylinder head lifting platform 3 is fixed to the front side of the lifting basket 44. The rear end of the chain 42 is equipped with a counterweight balance block 43.

[0028] The structure of the first lifting mechanism 4 is the same as that of the second lifting mechanism 6. Both the first lifting mechanism 4 and the second lifting mechanism 6 are equipped with a fixing rod 11 on the side near the overhead chain conveyor platform 5. The other end of the fixing rod 11 is connected to the overhead chain conveyor platform 5. Guardrails 10 are installed above and below the first lifting mechanism 4 and the second lifting mechanism 6, as well as on the outer side of the overhead chain conveyor platform 5. The self-cooling mechanism includes a cover 8 installed above the air-cooled conveyor chain 1 and the overhead chain conveyor platform 5. A cooling fan 9 is installed through the upper surface of the cover 8. The cooling fan 9 is inclined. A support frame 71 is fixed to the bottom surface of the rotating chain plate 7. A support base 73 is connected to the bottom surface of the support frame 71. A fixed base 74 is rotatably installed on the bottom surface of the support base 73. A motor is installed through the bottom surface of the fixed base 74. The output end of the motor is connected to the bottom surface of the support base 73.

[0029] After the engine cylinder head is cast, it is picked up by a robot and placed on the rotating chain plate 7 behind the air-cooled conveyor chain plate 1. The rotating chain plate 7 then transports the engine cylinder head onto the air-cooled conveyor chain plate 1, which in turn transports it forward to the rotating chain plate 7 in front of it. At the same time, the cooling fan 9 installed inside the protective cover 8 on the air-cooled conveyor chain plate 1 is started by the PLC controller installed in the conveying mechanism. The cooling fan 9 blows air onto the upper surface of the air-cooled conveyor chain plate 1, thereby effectively cooling the engine cylinder head on the air-cooled conveyor chain plate 1 and preventing the engine cylinder head from overheating after the forming process.

[0030] When the front rotating chain plate 7 needs to transport the engine cylinder head to the inner rotating transition chain plate 2, the PLC controller controls the motor installed through the bottom of the fixed base 74. The output end of the motor drives the support base plate 73, which is rotated and installed on the top of the fixed base 74, to rotate 90°. This causes the support base plate 73 to drive the support frame 71 and the rotating chain plate 7 to rotate 90° together. At this time, the output end of the rotating chain plate 7 faces the rotating transition chain plate 2, and the rotating chain plate 7 and the rotating transition chain plate 2 change from being perpendicular to each other to being parallel. Then the rotating chain plate 7 transports the engine cylinder head above to the rotating transition chain plate 2, and the rotating transition chain plate 2 transports the engine cylinder head above to the cylinder head lifting platform 3.

[0031] Next, the motor above the first lifting mechanism 4 is started. The motor drives the rotating shaft 41 and the outer gear to rotate, and the gear drives the chain 42 to rotate. At this time, the front end of the chain 42 drives the lifting basket 44 and the cylinder head lifting platform 3 to move upward, and the rear end of the chain 42 drives the counterweight block 43 to move downward. When the cylinder head lifting platform 3 rises to the same height as the overhead chain conveyor platform 5, the rising of the cylinder head lifting platform 3 is stopped. Then, the chain conveyor mechanism 31 inside the cylinder head lifting platform 3 is started. The chain conveyor mechanism 31 transports the engine cylinder head onto the overhead chain conveyor platform 5, and at the same time, the overhead chain... The conveyor platform 5 is also equipped with a protective cover 8 and a cooling fan 9. The cooling fan 9 is started to further cool the engine cylinder head on the overhead conveyor platform 5. Then the overhead conveyor platform 5 transports the engine cylinder head to the cylinder head lifting platform 3 installed on the second lifting mechanism 6. Then, as shown above, the second lifting mechanism 6 drives the cylinder head lifting platform 3 to descend, so that the cylinder head lifting platform 3 transports the engine cylinder head downward to the designated work position. Therefore, this vertical conveying mechanism can meet the conveying needs of different directions and different height positions, realize unmanned automatic transfer, and improve the conveying efficiency.

[0032] Example 2: The engine cylinder head self-cooled vertical conveying mechanism in this example, based on Example 1, allows for adjustment of the distance between the rotated chain plate 7 and the rotating transition chain plate 2 after rotation. This prevents the distance between the rotated chain plate 7 and the rotating transition chain plate 2 from being too large, which would affect the stability of the engine cylinder head transfer and conveying. For the specific structure, please refer to the attached diagram. Figure 9 As shown, two guide rail assemblies 75 are symmetrically installed on the upper surface of the support base plate 73, and the bottom surface of the support frame 71 forms a sliding structure with the support base plate 73 through the guide rail assemblies 75. An electric push rod 72 is installed in the middle of the upper surface of the support base plate 73, and the output end of the electric push rod 72 is connected to the bottom surface of the support frame 71.

[0033] When the rotating chain plate 7 rotates 90°, its output end faces the rotating transition chain plate 2. The rotating chain plate 7 and the rotating transition chain plate 2 change from being perpendicular to each other to being parallel. At this point, the electric push rod 72 is activated. The output end of the electric push rod 72 drives the support frame 71 to move towards the rotating transition chain plate 2. The support frame 71 slides stably on the support base plate 73 via the guide rail assembly 75, thus stably driving the rotating chain plate 7 towards the rotating transition chain plate 2. Therefore, the distance between the rotated rotating chain plate 7 and the rotating transition chain plate 2 can be reduced, preventing the distance between them from being too large and affecting the stability of the engine cylinder head transport.

[0034] Both the bottom of the counterweight 43 and the bottom of the first lifting mechanism 4 are equipped with buffer pads 45.

[0035] By setting the buffer pad 45, a large impact between the bottom of the cylinder head lifting platform 3 and the bottom of the first lifting mechanism 4 can be avoided. At the same time, a pressure sensor can be installed in the buffer pad 45. When the pressure sensor in the buffer pad 45 detects that the pressure is greater than the threshold, it indicates that the chain 42 connected above the counterweight balance block 43 is broken. At this time, the pressure sensor transmits this signal to the central processing module in the conveying mechanism. The central processing module controls the alarm in the conveying mechanism to sound an alarm, so as to provide timely warning of the chain 42 breakage.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
