Description

Technical Field

[0001] This utility model relates to the field of cylinder head technology, specifically to a pretreatment device for insert rings in engine aluminum alloy cylinder heads. Background Technology

[0002] The pretreatment device for insert rings in engine aluminum alloy cylinder heads is a special equipment for pretreatment of insert rings in engine aluminum alloy cylinder heads. Its core function is to improve the bonding performance, surface quality and subsequent assembly reliability of the insert ring and the aluminum alloy cylinder head through specific processes, laying the foundation for the composite processing of the insert ring and the cylinder head.

[0003] Among them, the Chinese utility model patent with authorization announcement number CN210560684U discloses a pretreatment device for insert rings for engine aluminum alloy cylinder heads. Although the patent has an inert gas filling the sealing chamber below the sealing cover plate, and the insert rings are aluminized in the sealing chamber, this method can prevent air from contacting the aluminum liquid in the sealing chamber. On the one hand, it prevents the aluminum liquid surface from contacting the air and causing an oxidation reaction, which is better for the preservation of aluminum liquid. On the other hand, the insert rings will not come into contact with air during the aluminizing process, resulting in better aluminizing effect and higher product quality.

[0004] However, the device still has certain defects in use: In this device, the insert ring is suspended in a fixed position after being inserted into the aluminum liquid and cannot be rotated or adjusted. During the immersion process, since the insert ring is always fixed in the same position in the aluminum liquid, the surrounding aluminum liquid will continuously absorb iron elements from the insert ring due to the continuous aluminizing reaction, resulting in a gradual increase in the iron content of the aluminum liquid in this area. Since the insert ring cannot change its contact position by rotating, it can only always be in contact with this part of the aluminum liquid with high iron content, which restricts the overall aluminizing efficiency, not only prolonging the pretreatment process time, but also making it difficult to achieve a fast and uniform aluminizing effect. Utility Model Content

[0005] The purpose of this invention is to provide a pretreatment device for inserting rings for engine aluminum alloy cylinder heads, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pretreatment device for insert rings for engine aluminum alloy cylinder heads, comprising a sealing chamber, wherein the sealing chamber is provided with two sets of receiving slots, an adjustment component, two sets of suspension components and an inert gas equipment box; The two sets of receiving tanks are used to hold molten aluminum; The adjustment component is used to adjust the position and angle of the setting ring, and the suspension component is used to suspend and fix the setting ring. The inert gas equipment box is used to deliver inert gas into the sealed chamber.

[0007] As a further preferred embodiment of this technical solution, the adjustment assembly consists of an adapter plate, a transmission gear shaft, and a drive gear. A first adjustment gear and a second adjustment gear are movably installed below the adapter plate, and the first adjustment gear and the second adjustment gear mesh with each other, while the second adjustment gear forms a meshing connection with the transmission gear shaft.

[0008] As a further preferred embodiment of this technical solution, the adjustment component further includes a drive gear and a drive motor, the output end of the drive motor being connected to the drive gear in a transmission connection, and the drive gear meshing with the transmission gear shaft.

[0009] As a further preferred embodiment of this technical solution, the adapter plate, the first adjusting tooth, the second adjusting tooth, and the transmission gear shaft are each provided in two sets, and the two sets of components are symmetrically distributed inside the sealed chamber. At the same time, the drive tooth and the transmission gear shafts at both ends are kept in a meshing state.

[0010] As a further preferred embodiment of this technical solution, the adjustment assembly also includes two sets of lifting cylinders, each set of lifting cylinders having a connecting block at its output end, and the output end of each set of lifting cylinders extending into the sealed chamber and connected to the corresponding adapter plate via the connecting block.

[0011] As a further preferred embodiment of this technical solution, each set of suspension components is equipped with a T-shaped support bracket. Each set of T-shaped support brackets is installed below the first adjusting tooth through a positioning hole reserved at its upper end, and each set of T-shaped support brackets has two sets of suspension hooks integrally formed at its lower end.

[0012] As a further preferred embodiment of this technical solution, a sealing partition is installed on one side of the sealed chamber, and a connecting door is configured on the sealing partition. The connecting door is made of a transparent material.

[0013] This utility model provides a pretreatment device for insert rings in engine aluminum alloy cylinder heads, which has the following beneficial effects: (1) By adjusting the coordination of the drive motor, transmission gear shaft and meshing gear in the component, this utility model can drive the suspension and the insert to achieve angular rotation. At the same time, the lifting cylinder can adjust the immersion depth of the insert in the aluminum liquid. Through this multi-dimensional adjustment, each part of the insert can be evenly contacted with the aluminum liquid, avoiding the difference in aluminum diffusion speed caused by local iron enrichment. This not only improves the consistency of the aluminum diffusion layer thickness, but also shortens the pretreatment time and improves the overall process efficiency.

[0014] (2) Since the adapter plate, the first adjusting tooth, the second adjusting tooth and the transmission tooth shaft are all set in two groups and symmetrically distributed, and the driving tooth meshes with the transmission tooth shaft at both ends at the same time, only one driving motor is needed to drive the two groups of transmission tooth shafts to rotate synchronously through the driving tooth, thereby realizing the synchronous rotation of the two groups of suspension components. With this design, there is no need to configure a driving source for the two groups of transmission structures separately, which reduces the number of driving components used and reduces the energy consumption and manufacturing cost of the equipment.

[0015] (3) This utility model ensures the airtightness of the inert gas environment inside the chamber by connecting the door with the sealing partition and the transparent window material on one side of the sealed chamber, and also makes it easy for operators to observe the internal aluminizing state in real time. At the same time, the design of two sets of symmetrically distributed receiving slots and hanging parts can process multiple inlay rings simultaneously. Combined with the automatic drive of the adjustment components, it reduces manual intervention and improves the convenience and continuity of operation. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figure 1-4 As shown in this embodiment, a pretreatment device for insert rings for an engine aluminum alloy cylinder head includes a sealing chamber 1. A sealing partition 2 is installed on one side of the sealing chamber 1. A connecting door 21 is configured on the sealing partition 2. The connecting door 21 is made of a transparent material. The sealing chamber 1 is provided with two sets of receiving slots 3, an adjustment component 4, two sets of suspension components 5, and an inert gas equipment box 6. The two sets of receiving slots 3 are used to hold molten aluminum. The adjustment component 4 is used to adjust the position and angle of the insert ring. The suspension components 5 are used to suspend and fix the insert ring. The inert gas equipment box 6 is used to deliver inert gas into the sealing chamber 1.

[0020] like Figure 1-4 As shown, the adjustment assembly 4 consists of an adapter plate 41, a transmission gear shaft 44, and a drive gear 45. A first adjustment gear 42 and a second adjustment gear 43 are movably mounted below the adapter plate 41, and the first adjustment gear 42 and the second adjustment gear 43 mesh with each other. The second adjustment gear 43 is meshed with the transmission gear shaft 44. The adjustment assembly 4 also includes a drive gear 45 and a drive motor 46. The output end of the drive motor 46 is connected to the drive gear 45, and the drive gear 45 meshes with the transmission gear shaft 44. It also includes two sets of lifting cylinders 47. The output ends of the two sets of lifting cylinders 47 are equipped with connecting blocks 48, and the output end of each set of lifting cylinders 47 extends into the sealed chamber 1 and is connected to the corresponding adapter plate 41 through the connecting blocks 48. Each set of suspension components 5 is equipped with a T-shaped support bracket 511. Each set of T-shaped support brackets 511 is installed below the first adjusting tooth 42 through the positioning hole reserved at its upper end. The lower end of each set of T-shaped support brackets 511 is integrally formed with two sets of suspension hooks 51.

[0021] In this scheme, firstly, open the transparent material connecting door 21 on the sealing partition 2, hang the inlay ring to be processed on the corresponding hook 51 on the T-shaped support 511, inject an appropriate amount of aluminum liquid into the two sets of receiving tanks 3, close the connecting door 21 to ensure the sealing chamber 1 is sealed, and then start the inert gas equipment box 6. The inert gas equipment box 6 continuously supplies inert gas into the sealing chamber 1 through the connecting pipe to create an anti-oxidation environment. (It should be noted that the inert gas equipment box 6 adopts the BKX series. This series of equipment boxes is a current mature product. Its specific working principle will not be described in detail here.) Then, the two sets of lifting cylinders 47 in the adjustment component 4 are activated. The output end of the lifting cylinder 47 extends into the sealed chamber 1 through the sealing structure. The connecting block 48 at its end drives the corresponding adapter plate 41 to descend synchronously, so that the ring on the suspension hook 51 gradually approaches the aluminum liquid in the receiving tank 3 until it is adjusted to the preset immersion depth. Finally, the drive motor 46 is started, and the output end of the drive motor 46 drives the drive gear 45 to rotate. Since the drive gear 45 is meshed with both sets of transmission gear shafts 44, it can drive the two sets of transmission gear shafts 44 to rotate synchronously. The transmission gear shafts 44 drive the meshing second adjusting gear 43 to rotate, and the second adjusting gear 43 then drives the meshing first adjusting gear 42 to rotate. In turn, the T-shaped support frame 511 connected below the first adjusting gear 42 drives the insert ring to rotate, so that all parts of the insert ring can be in uniform contact in the aluminum liquid, thus completing the aluminizing pretreatment.

[0022] By adjusting the coordination of the drive motor 46, transmission gear shaft 44, and meshing gear in component 4, the suspension component 5 and the insert ring can be rotated at an angle. At the same time, the lifting cylinder 47 can adjust the immersion depth of the insert ring in the molten aluminum. This multi-dimensional adjustment allows all parts of the insert ring to contact the molten aluminum evenly, avoiding differences in the aluminizing speed caused by local iron enrichment. This not only improves the consistency of the aluminized layer thickness but also shortens the pretreatment time and improves the overall process efficiency.

[0023] like Figure 2-4 As shown, the adapter plate 41, the first adjusting tooth 42, the second adjusting tooth 43 and the transmission gear shaft 44 are each provided in two sets. The two sets of components are symmetrically distributed inside the sealed chamber 1. At the same time, the drive tooth 45 and the transmission gear shaft 44 at both ends are in a meshing state.

[0024] In this scheme, the drive motor 46 is started, and its output end drives the drive gear 45 to start rotating. The two sets of transmission gear shafts 44 will rotate simultaneously and synchronously. As the two sets of transmission gear shafts 44 rotate synchronously, the two sets of second adjusting teeth 43 that mesh with the transmission gear shafts 44 will also rotate synchronously. Since the second adjusting teeth 43 mesh with the first adjusting teeth 42, the two sets of first adjusting teeth 42 will achieve synchronous operation under the drive of the second adjusting teeth 43. Since the two sets of first adjusting teeth 42 are respectively connected to the corresponding suspension parts 5, under the synchronous operation of the first adjusting teeth 42, the two sets of suspension parts 5 will carry the suspended inserts to perform synchronous angle adjustments, thereby ensuring that the two sets of inserts maintain a consistent action state during the preprocessing process.

[0025] By setting the adapter plate 41, the first adjusting tooth 42, the second adjusting tooth 43, and the transmission gear shaft 44 into two sets and symmetrically distributed, and by having the drive tooth 45 mesh with the transmission gear shaft 44 at both ends simultaneously, only one drive motor 46 is needed to drive the two sets of transmission gear shafts 44 to rotate synchronously through the drive tooth 45, thereby achieving synchronous rotation of the two sets of suspension components 5. This design eliminates the need to configure drive sources for the two sets of transmission structures separately, reducing the number of drive components used and lowering equipment energy consumption and manufacturing costs.

[0026] This utility model provides a pretreatment device for insert rings in engine aluminum alloy cylinder heads, and its working principle is as follows: First, open the transparent material connecting door 21 on the sealing partition 2, hang the inlay ring to be pretreated on the hanging hook 51 at the lower end of the T-shaped support 511 of the two sets of hanging parts 5, inject an appropriate amount of aluminum liquid into the two sets of receiving tanks 3 in the sealing chamber 1, close the connecting door 21, and then start the BKX series inert gas equipment box 6 to continuously deliver inert gas into the sealing chamber 1 through the connecting pipe to create an anti-oxidation treatment environment; Next, the two sets of lifting cylinders 47 in the adjustment assembly 4 are activated. The output end of the lifting cylinder 47 extends into the sealed chamber 1 through the sealing structure. The connecting block 48 at its end will drive the corresponding adapter plate 41 to descend synchronously. As the adapter plate 41 descends, the second adjusting tooth 43 and the transmission gear shaft 44 always remain in mesh. The T-shaped support bracket 511 and the insert on the suspension hook 51 connected to the first adjusting tooth 42 movably installed below the adapter plate 41 also gradually descend until the insert is immersed in the aluminum liquid in the receiving tank 3 at a preset depth. Then, the drive motor 46 is started. The output end of the drive motor 46 drives the drive gear 45 to rotate. Since the drive gear 45 is engaged with the two sets of symmetrically distributed transmission gear shafts 44, it will drive the two sets of transmission gear shafts 44 to rotate synchronously. When the transmission gear shaft 44 rotates, it drives the second adjusting gear 43 that is engaged with it to rotate. The second adjusting gear 43 drives the first adjusting gear 42 that is engaged with it to rotate. Then, through the T-shaped support bracket 511 connected below the first adjusting gear 42, it drives the inlay rings on the two sets of suspension parts 5 to rotate synchronously, so that each part of the inlay ring is in uniform contact in the aluminum liquid, and the aluminum infiltration pretreatment is completed. After the aluminizing pretreatment is completed, the output ends of the two sets of lifting cylinders 47 are retracted, and the connecting block 48 drives the adapter plate 41, the first adjusting tooth 42, the T-shaped support frame 511 and the insert to rise, so that the insert is separated from the aluminum liquid. The drive motor 46 is turned off to stop the rotation of the insert. The inert gas equipment box 6 is turned off to stop the supply of inert gas to the sealed chamber 1. Finally, the connecting door 21 is opened and the pretreated insert is removed.
