Description

Technical Field

[0001] The invention relates to the technical field of shift hub production, and in particular to a fully automatic production device for a shift hub. Background Art

[0002] The shift hub (also called shift fork or shift gear) is a key component in a car transmission, mainly used in manual transmissions. Its function is to push the gears to engage or disengage when shifting gears, thereby achieving switching between different gears.

[0003] The shift hub needs to go through the following steps during the production process: 1. Use the pouring robot to scoop out some molten aluminum from the molten aluminum pool and pour it into the casting machine; 2. Use the temperature control device to cool the mold; 3. The casting machine opens the mold, and the pick-up device clamps the product to obtain the newly plasticized shift hub; 4. The pick-up device moves along the linear rail and puts the product into the cold water pool for cooling; 5. After cooling, the pick-up device hands the product to the first robot arm, and the robot arm puts the product on the placement table in turn; 7. The rear robot arm puts the product into the riser machine in turn and performs riser removal on the product to ensure that the feeding speed of the robot arm is the same as the cutting speed of the riser machine; 8. After the removal is completed, the product is placed in the guide trough for manual inspection; 9. The molten aluminum pool needs to be cleaned and maintained regularly. Before cleaning, all the molten aluminum that can be discharged from the molten aluminum pool needs to be discharged to reduce the difficulty of cleaning, and then the molten aluminum pool is cleaned with 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, which is easy to cause pollution to the environment or the aluminum liquid.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-5 As shown, the present invention is a fully automatic production equipment for a shift hub, including an aluminum liquid pool 14, the aluminum liquid pool 14 includes an insulation cylinder 1, a heating component 11 is arranged inside the insulation cylinder 1, the heating component 11 includes a heating coil, the heating coil is arranged inside the cylinder body of the insulation cylinder 1, and an inner carrier cylinder 2 is coaxially fixedly sleeved in the middle of the insulation cylinder 1. The device also includes a load-bearing bucket 5 and a pushing component 3 for pushing the load-bearing bucket 5 to move up and down. The load-bearing bucket 5 and the inner carrier cylinder 2 are spliced ​​into a cavity for carrying aluminum liquid. The pushing component 3 is arranged inside the insulation cylinder 1, and a push cylinder 4 slidingly matched with the inner carrier cylinder 2 is arranged at the output end of the pushing component 3. The load-bearing bucket 5 is fixedly connected to the end of the push cylinder 4 away from the pushing component 3. The pushing component 3 can push the push cylinder 4 to move upward, thereby pushing the load-bearing bucket 5 to move upward along the inner carrier cylinder 2, so as to scrape the aluminum liquid stuck to the inner wall of the inner carrier cylinder 2 during cleaning. It should be noted that when the load-bearing 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 causing damage to the load-bearing bucket 5.

[0028] A storage cylinder 6 is provided at the bottom of the carrying bucket 5, and the storage cylinder 6 is used to carry the remaining aluminum liquid. An opening and closing component for controlling the through state of the storage cylinder 6 is provided on the top of the storage cylinder 6. A lifting component for adjusting the internal storage volume of the storage cylinder 6 is provided at the bottom of the storage cylinder 6. A winding ring plate 12 is fixedly connected to the opening of the upper end of the inner carrier cylinder 2 to reduce the loss of heat inside the inner carrier cylinder 2. The bottom of the winding ring plate 12 is provided with an inclined surface matching the upper edge of the carrying bucket 5. When it is necessary to clean the aluminum liquid pool 14, the opening and closing component is opened, so that the remaining aluminum liquid in the aluminum liquid pool 14 can enter the storage cylinder 6 along the carrying bucket 5. The storage space inside the inner carrier cylinder 2 is increased through the lifting component, thereby facilitating the collection of aluminum liquid. The rear driving push component 3 drives the carrying bucket 5 to move upward, and the aluminum liquid adhering to the inner wall of the inner carrier cylinder 2 is cleaned through the carrying bucket 5. After scraping, the scraped aluminum liquid can enter the storage tube 6 along the carrying bucket 5. When the upper edge of the carrying bucket 5 is docked with the bottom of the winding ring plate 12, the aluminum liquid on the edge of the carrying bucket 5 will be squeezed to the middle of the carrying bucket 5 under the action of the winding ring plate 12, thereby accelerating the collection process of the aluminum liquid. The carrying bucket 5 then moves down a distance to avoid the carrying bucket 5 and the winding ring plate 12 from sticking to each other. Then the opening and closing component is closed, so that the aluminum liquid is sealed inside the storage tube 6, thereby reducing the oxidation and pollution of the aluminum liquid by the external environment. When it is used next time, the carrying bucket 5 is reset, and aluminum liquid is poured into the inner carrying tube 2. The heating component 11 is used for heat preservation, and the solidified aluminum liquid inside the storage tube 6 will gradually melt. After a period of time, the opening and closing component is opened, and the internal volume of the storage tube 6 is reduced through the lifting component, thereby squeezing the aluminum liquid back to the top of the carrying bucket 5 to reduce the waste of aluminum liquid.

[0029] In the present invention, in order to facilitate the collection of filtrate, a flow opening 8 for circulating aluminum liquid is opened inside the storage cylinder 6 near one end of the carrying bucket 5, and the opening and closing assembly includes a fixed block 19 fixedly connected to one side of the storage cylinder 6, and a first pneumatic telescopic rod 7 is fixedly connected to the fixed 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 aluminum liquid pool 14 is in operation, the closing plate 13 is used to block the flow opening 8. When the aluminum liquid pool 14 is cleaned, the first pneumatic telescopic rod 7 contracts to drive the closing plate 13 to be staggered with the flow opening 8, thereby facilitating the collection of aluminum liquid.

[0030] In the present 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, and 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 molten aluminum, the second pneumatic telescopic rod 9 contracts, driving the sealing plug 10 to move downward, thereby increasing the storage space above the storage cylinder 6, thereby facilitating the collection of molten aluminum.

[0031] In the present invention, in order to push the push tube 4, the pushing assembly 3 includes a telescopic cylinder and a push plate arranged at the output end of the telescopic cylinder. The telescopic cylinder is arranged inside the insulation tube 1, and the upper end of the push plate is fixedly connected to the push tube 4. The telescopic cylinder drives the push plate to move up, thereby driving the push tube 4 and the carrying bucket 5 to move up.

[0032] In the present invention, in order to ensure the service life of the device, the inner carrier tube 2, the closing plate 13, the carrying bucket 5, the storage tube 6 and the sealing plug 10 are all made of silicon nitride ceramics, and the outer sides of the carrying bucket 5 and the sealing plug 10 are surrounded by silicon carbide sealing rings. Silicon nitride ceramics have high hardness, high thermal stability, good thermal shock resistance and chemical corrosion resistance, especially when in contact with molten aluminum, it shows excellent corrosion resistance, and chemical silicon carbide has very 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 FIG. 5 , in this embodiment, before the application document is implemented, a casting robot arm 15 for scooping molten aluminum is provided on one side of the molten aluminum pool 14, and 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 molten aluminum is cooled by the casting machine 16 to complete the shaping of the shift hub. A linear clamp 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 clamp rail 17. After the casting machine 16 opens the mold, the linear clamp rail 17 takes the shift hub away from the casting machine 16 and puts it into the cold water pool for soaking for a period of time. A transport robot 18 is provided on one side of the linear clamp rail 17, and a riser machine is provided on one side of the transport robot 18. After the shift hub is soaked, the shift hub is handed to the transport robot 18 through the linear clamp rail 17, and the transport robot 18 puts the shift hub into the operating area of ​​the riser machine for riser cutting, thereby realizing the production of the shift hub.

[0034] The working principle of the present invention is as follows: when the aluminum liquid pool 14 needs to be cleaned, the first pneumatic telescopic rod 7 contracts to drive the closing plate 13 to be staggered with the flow opening 8, so that the flow opening 8 is in a flow state, so that the remaining aluminum liquid in the aluminum liquid pool 14 can enter the storage tube 6 along the carrying bucket 5, and the second pneumatic telescopic rod 9 contracts to drive the sealing plug 10 to move downward, so that the storage space above the storage tube 6 is increased, thereby facilitating the collection of aluminum liquid, and then the driving push component 3 drives the carrying bucket 5 to move upward, and the aluminum liquid adhering to the inner wall of the inner carrying tube 2 is scraped off by the carrying bucket 5, and the scraped aluminum liquid can enter the storage tube 6 along the carrying bucket 5 to collect the aluminum liquid, and when the upper edge of the carrying bucket 5 is docked with the bottom of the winding ring plate 12, the aluminum liquid on the edge of the carrying bucket 5 will be squeezed to the middle of the carrying bucket 5 under the action of the winding ring plate 12, thereby accelerating the collection process of the aluminum liquid, and then the carrying bucket 5 moves down a distance to avoid the carrying bucket 5 from The bucket 5 and the winding ring plate 12 are adhered to each other, and then the flow opening 8 is closed, so that the aluminum liquid is sealed inside the storage tube 6, thereby reducing the oxidation and pollution of the aluminum liquid by the external environment. Waiting for the aluminum liquid to solidify, the upward movement of the carrying bucket 5 will make it easier for the staff to clean the carrying bucket 5, thereby improving the cleaning effect and reducing manpower consumption. It should be noted that the volume of the aluminum liquid 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 tube 6. When the aluminum liquid pool 14 is used again, the carrying bucket 5 is reset, and aluminum liquid is poured into the inner carrier tube 2. The heating component 11 is used for insulation, and the solidified aluminum liquid inside the storage tube 6 will gradually melt. After a period of time, the flow opening 8 is opened, and the second pneumatic telescopic rod 9 is extended, driving the sealing plug 10 to move upward, and the internal volume of the storage tube 6 is reduced, thereby squeezing the aluminum liquid back to the top of the carrying bucket 5 to reduce the waste of aluminum liquid.

[0035] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
