Description

Technical Field

[0001] This invention relates to the field of gear shift hub manufacturing technology, and specifically to a fully automated gear shift hub production equipment. Background Technology

[0002] The shift hub (also known as the shift fork or shift gear) is a key component in a car transmission, mainly used in manual transmissions. Its function is to drive the gears to engage or disengage during gear shifting, thereby enabling the switching of different gears.

[0003] The production process of the shift hub involves the following steps: 1. A portion of molten aluminum is scooped from the aluminum pool by a casting robot and poured into the casting machine; 2. The mold is cooled by a temperature control device; 3. The casting machine opens the mold, and the part-removing device clamps the product, resulting in a freshly molded shift hub; 4. The part-removing device moves along the guide rail and places the product into a cold water pool for cooling; 5. After cooling, the part-removing device hands the product to the first robotic arm, which then places the product onto the placement table; 7. The subsequent robotic arms place the product into the riser machine for riser removal, ensuring that the feeding speed of the robotic arm matches the cutting speed of the riser machine; 8. After removal, the product is placed into the guide trough for manual inspection; 9. The aluminum pool needs regular cleaning and maintenance. Before cleaning, all molten aluminum that can be drained from the pool should be discharged to reduce cleaning difficulty. The pool is then cleaned using a high-pressure water gun and a brush.

[0004] The shortcomings of the existing technical solutions are that, in the process of cleaning the aluminum liquid pool, the aluminum liquid needs to be discharged from the aluminum liquid pool. When the aluminum liquid is discharged from the aluminum liquid pool, it is easy to cause pollution to the environment or the aluminum liquid. After discharge, some aluminum liquid will stick to the carrier container and cannot be recycled, thus causing waste of resources. In addition, because the aluminum liquid pool has a certain depth, it is not convenient for workers to clean it, which is time-consuming and labor-intensive. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic production equipment for gear shift hubs, which solves the problems of the need to discharge aluminum liquid from the aluminum liquid pool during the cleaning process. The discharge of aluminum liquid from the aluminum liquid pool can easily cause pollution to the environment or the aluminum liquid itself. After discharge, some aluminum liquid will stick to the carrier container and cannot be recycled, thus wasting resources. In addition, the aluminum liquid pool has a certain depth, which makes it inconvenient, time-consuming and labor-intensive for workers to clean it.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A fully automatic production equipment for gear shift hubs includes an aluminum liquid tank, which includes an insulation cylinder. A heating component is installed inside the insulation cylinder. An inner carrier cylinder is coaxially and fixedly sleeved in the middle of the insulation cylinder. The device also includes a carrier bucket and a pushing component for moving the carrier bucket up and down. The pushing component is located inside the insulation cylinder. A pusher cylinder that slides with the inner carrier cylinder is installed at the output end of the pushing component. The carrier bucket is fixedly connected to the end of the pusher cylinder away from the pushing component. A storage cylinder is installed at the bottom of the carrier bucket. An opening and closing component for controlling the through-state of the storage cylinder is installed at the top of the storage cylinder. A lifting component for adjusting the internal storage volume of the storage cylinder is installed at the bottom of the storage cylinder.

[0008] As a further aspect of the present invention: the storage cylinder has a flow opening for the flow of molten aluminum at one end near the bearing hopper, and the opening and closing assembly includes a fixing block fixedly connected to one side of the storage cylinder, and a first pneumatic telescopic rod fixedly connected to the fixing block. The output end of the first pneumatic telescopic rod is provided with a closing plate that penetrates the inner wall of the storage cylinder and cooperates with the flow opening.

[0009] As a further aspect of the present invention: the lifting assembly includes a second pneumatic telescopic rod fixedly connected to the bottom of the storage cylinder, and the output end of the second pneumatic telescopic rod is fixedly connected to a sealing plug that slides inside the storage cylinder.

[0010] As a further aspect of the present invention: a spiral ring plate is fixedly connected to the upper opening of the inner carrier cylinder.

[0011] As a further aspect of the present invention: the bottom of the winding ring plate is provided with an inclined surface that matches the upper edge of the bearing bucket.

[0012] As a further aspect of the present invention: the heating component includes a heating coil, which is disposed inside the insulation cylinder.

[0013] As a further aspect of the present invention: the pushing component includes a telescopic cylinder and a push plate disposed at the output end of the telescopic cylinder, the telescopic cylinder being disposed inside the heat preservation cylinder, and the upper end of the push plate being fixedly connected to the push cylinder.

[0014] As a further aspect of the present invention: the inner carrier cylinder, the closing plate, the carrier hopper, the storage cylinder and the sealing plug are all made of silicon nitride ceramic material, and the carrier hopper and the sealing plug are all surrounded by silicon carbide sealing rings.

[0015] The beneficial effects of this invention are:

[0016] 1. In this invention, when the aluminum liquid pool needs to be cleaned, the first pneumatic telescopic rod retracts, causing the closing plate to be misaligned with the flow opening, so that the flow opening is in a flow state, allowing the remaining aluminum liquid in the aluminum liquid pool to enter the storage cylinder along the carrying hopper. The second pneumatic telescopic rod retracts, causing the sealing plug to move downward, increasing the storage space above the storage cylinder, thereby facilitating the collection of aluminum liquid. Then, the drive component moves the carrying hopper upward, scraping off the aluminum liquid adhering to the inner wall of the inner carrying cylinder through the carrying hopper. The scraped aluminum liquid can enter the storage cylinder along the carrying hopper. Subsequently, the flow opening closes, sealing the aluminum liquid inside the storage cylinder, thereby reducing the oxidation and pollution of the aluminum liquid by the external environment. The upward movement of the carrying hopper makes it easier for workers to clean the carrying hopper, improving the cleaning effect. Moreover, the carrying hopper automatically cleans the inner wall of the inner carrying cylinder, reducing the consumption of manpower.

[0017] 2. In this invention, a spiral ring plate is provided above the inner carrier cylinder to reduce the loss of heat inside the inner carrier cylinder. The bottom of the spiral ring plate is provided with an inclined surface that matches the upper edge of the carrier bucket. During the process of the carrier bucket moving upward to scrape the aluminum liquid on the inner wall of the inner carrier cylinder, when the upper edge of the carrier bucket connects with the bottom of the spiral ring plate, the aluminum liquid on the edge of the carrier bucket will be squeezed into the middle of the carrier bucket under the action of the spiral ring plate, thereby accelerating the collection process of the aluminum liquid and reducing the collection time of the aluminum liquid. Then the carrier bucket moves down a certain distance to avoid the carrier bucket and the spiral ring plate sticking to each other.

[0018] 3. In this invention, when the aluminum liquid pool is used again, the carrying hopper is reset, aluminum liquid is poured into the inner carrying cylinder, and the heating component is used to keep it warm. The solidified aluminum liquid inside the storage cylinder will gradually melt. After a period of time, the flow opening opens, the second pneumatic telescopic rod extends, and the sealing plug moves upward, reducing the internal volume of the storage cylinder, thereby squeezing the aluminum liquid back above the carrying hopper, thus reducing the waste of aluminum liquid.

[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 Figure 1-5 As shown, this invention is a fully automatic production equipment for gear shifting hubs, including an aluminum liquid tank 14, an aluminum liquid tank 14 including a heat preservation cylinder 1, a heating component 11 inside the heat preservation cylinder 1, the heating component 11 including a heating coil, the heating coil being disposed inside the heat preservation cylinder 1, an inner carrier cylinder 2 being coaxially fixedly sleeved in the middle of the heat preservation cylinder 1, the device also includes a carrier bucket 5 and a pushing component 3 for pushing the carrier bucket 5 to move up and down, the carrier bucket 5 and the inner carrier cylinder 2 are spliced ​​to form a cavity for carrying aluminum liquid, the pushing component 3 is disposed inside the heat preservation cylinder 1, the output end of the pushing component 3 is provided with a pusher 4 that slides with the inner carrier cylinder 2, the carrier bucket 5 is fixedly connected to the end of the pusher 4 away from the pushing component 3, the pushing component 3 can push the pusher 4 to move upward, thereby pushing the carrier bucket 5 to move upward along the inner carrier cylinder 2, so as to scrape off the aluminum liquid adhering to the inner wall of the inner carrier cylinder 2 during cleaning. It should be noted that when the carrier bucket 5 moves upward, it is necessary to ensure that the internal temperature of the aluminum liquid does not drop, to avoid the aluminum liquid solidifying and damaging the carrier bucket 5.

[0028] A storage cylinder 6 is installed at the bottom of the carrying hopper 5 to hold the remaining molten aluminum. An opening and closing assembly is installed at the top of the storage cylinder 6 to control its open / closed state. A lifting assembly is installed at the bottom of the storage cylinder 6 to adjust its internal storage volume. A spiral ring plate 12 is fixedly connected to the upper opening of the inner carrying cylinder 2 to reduce heat loss. The bottom of the spiral ring plate 12 has an inclined surface that matches the upper edge of the carrying hopper 5. When the molten aluminum pool 14 needs cleaning, the opening and closing assembly opens, allowing the remaining molten aluminum in the pool 14 to flow along the carrying hopper 5 into the storage cylinder 6. The lifting assembly increases the storage space inside the inner carrying cylinder 2, facilitating the collection of molten aluminum. The rear drive component 3 then moves the carrying hopper 5 upwards, allowing the molten aluminum adhering to the inner wall of the inner carrying cylinder 2 to be removed. The scraped-off molten aluminum can enter the storage cylinder 6 along the carrying hopper 5. When the upper edge of the carrying hopper 5 aligns with the bottom of the spiral ring plate 12, the molten aluminum on the edge of the carrying hopper 5 will be squeezed to the middle of the carrying hopper 5 by the spiral ring plate 12, thereby accelerating the collection process of the molten aluminum. Then the carrying hopper 5 moves down a certain distance to prevent the carrying hopper 5 from sticking to the spiral ring plate 12. Subsequently, the opening and closing component closes, so that the molten aluminum is sealed inside the storage cylinder 6, thereby reducing the oxidation and pollution of the molten aluminum by the external environment. When used again, the carrying hopper 5 is reset, and molten aluminum is poured into the inner carrying cylinder 2. The heating component 11 is used to keep it warm, and the solidified molten aluminum inside the storage cylinder 6 will gradually melt. After a period of time, the opening and closing component opens, and the lifting component reduces the internal volume of the storage cylinder 6, thereby squeezing the molten aluminum back to the top of the carrying hopper 5, thus reducing the waste of molten aluminum.

[0029] In this invention, to facilitate the collection of filtrate, the storage cylinder 6 has a flow opening 8 for the flow of molten aluminum at one end near the bearing hopper 5. The opening and closing assembly includes a fixing block 19 fixedly connected to one side of the storage cylinder 6. A first pneumatic telescopic rod 7 is fixedly connected to the fixing block 19. The output end of the first pneumatic telescopic rod 7 is provided with a closing plate 13 that penetrates the inner wall of the storage cylinder 6 and cooperates with the flow opening 8. When the molten aluminum pool 14 is in operation, the closing plate 13 is used to block the flow opening 8. When cleaning the molten aluminum pool 14, the first pneumatic telescopic rod 7 retracts, causing the closing plate 13 to be misaligned with the flow opening 8, thereby facilitating the collection of molten aluminum.

[0030] In this invention, in order to control the volume of the storage cylinder 6, the lifting assembly includes a second pneumatic telescopic rod 9 fixedly connected to the bottom of the storage cylinder 6. The output end of the second pneumatic telescopic rod 9 is fixedly connected to a sealing plug 10 that slides inside the storage cylinder 6. When it is necessary to collect aluminum liquid, the second pneumatic telescopic rod 9 retracts, causing the sealing plug 10 to move down, thereby increasing the storage space above the storage cylinder 6, which facilitates the collection of aluminum liquid.

[0031] In this invention, in order to push the pusher cylinder 4, the pushing component 3 includes a telescopic cylinder and a push plate disposed at the output end of the telescopic cylinder. The telescopic cylinder is disposed inside the heat preservation cylinder 1, and the upper end of the push plate is fixedly connected to the pusher cylinder 4. The telescopic cylinder drives the push plate to move upward, thereby driving the pusher cylinder 4 and the carrying bucket 5 to move upward.

[0032] In this invention, to ensure the service life of the device, the inner carrier cylinder 2, the closing plate 13, the carrier hopper 5, the storage cylinder 6, and the sealing plug 10 are all made of silicon nitride ceramic. The carrier hopper 5 and the sealing plug 10 are both surrounded by silicon carbide sealing rings. Silicon nitride ceramic has high hardness, high thermal stability, good thermal shock resistance, and chemical corrosion resistance. In particular, it exhibits excellent corrosion resistance when in contact with molten aluminum. Silicon carbide has high hardness and good heat resistance, and can operate in high temperature and corrosive environments, thereby ensuring the service life of the device.

[0033] like Figure 1 As shown in Figure 5, in this embodiment, before implementation, a casting robot arm 15 for scooping molten aluminum is provided on one side of the molten aluminum pool 14. A casting machine 16 for shaping the molten aluminum is provided on one side of the casting robot arm 15. The casting robot arm 15 pours the scooped molten aluminum into the casting machine 16, and the casting machine 16 cools the molten aluminum, thus completing the shaping of the shift hub. A linear clamping rail 17 is provided on one side of the casting machine 16, and a cold water pool is provided at the bottom of the linear clamping rail 17. After the casting machine 16 opens the mold, the linear clamping rail 17 carries the shift hub away from the casting machine 16 and places it in the cold water pool for soaking for a period of time. A handling robot 18 is provided on one side of the linear clamping rail 17, and a riser machine is provided on one side of the handling robot 18. After the shift hub is soaked, it is handed to the handling robot 18 through the linear clamping rail 17. The handling robot 18 places the shift hub into the riser machine's working area for riser cutting, thereby realizing the production of the shift hub.

[0034] The working principle of this invention is as follows: When the aluminum liquid pool 14 needs to be cleaned, the first pneumatic telescopic rod 7 retracts, causing the closing plate 13 to be misaligned with the flow opening 8, so that the flow opening 8 is in a flow state, allowing the remaining aluminum liquid in the aluminum liquid pool 14 to enter the storage cylinder 6 along the carrying hopper 5. The second pneumatic telescopic rod 9 retracts, causing the sealing plug 10 to move downward, increasing the storage space above the storage cylinder 6, thereby facilitating the collection of aluminum liquid. Then, the drive component 3 moves the carrying hopper 5 upward, scraping off the aluminum liquid adhering to the inner wall of the inner carrying cylinder 2 through the carrying hopper 5. The scraped aluminum liquid can enter the storage cylinder 6 along the carrying hopper 5, realizing the collection of aluminum liquid. When the upper edge of the carrying hopper 5 aligns with the bottom of the spiral ring plate 12, the aluminum liquid on the edge of the carrying hopper 5 will be squeezed to the middle of the carrying hopper 5 under the action of the spiral ring plate 12, thereby accelerating the collection process of aluminum liquid. Finally, the carrying hopper 5 moves downward a certain distance to avoid bearing The hopper 5 and the spiral ring plate 12 are bonded together. Then the flow opening 8 is closed, sealing the molten aluminum inside the storage cylinder 6, thereby reducing the oxidation and contamination of the molten aluminum by the external environment. After the molten aluminum solidifies, the support hopper 5 moves upward, making it easier for workers to clean it, thus improving the cleaning effect and reducing manpower consumption. It should be noted that the volume of the molten aluminum shrinks after solidification, so after the flow opening 8 is closed, the closing plate 13 and the flow opening 8 need to be slightly offset to ensure the pressure balance inside and outside the storage cylinder 6. When the molten aluminum pool 14 is used again, the support hopper 5 is reset, and molten aluminum is poured into the inner cylinder 2. The heating component 11 is used to keep it warm, and the solidified molten aluminum inside the storage cylinder 6 will gradually melt. After a period of time, the flow opening 8 opens, the second pneumatic telescopic rod 9 extends, and the sealing plug 10 moves upward, reducing the internal volume of the storage cylinder 6, thereby squeezing the molten aluminum back above the support hopper 5 to reduce the waste of molten aluminum.

[0035] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
