Description

Technical Field

[0001] This utility model relates to the field of casting, specifically a high-stability small compressor bearing housing casting device. Background Technology

[0002] In the manufacturing process of small compressors, the bearing housing, as a core transmission component, directly determines the compressor's operating efficiency and service life through its structural stability and precision. Due to the small size and intricate internal structure of small compressor bearing housings, extremely high requirements are placed on the casting precision, ease of operation, and casting quality of the casting equipment. Therefore, the rationality of the casting equipment design becomes a key factor affecting the production efficiency of bearing housings.

[0003] Currently, most casting equipment for small compressor bearing housings in the industry adopts a fixed casting structure, meaning the casting module is in a fixed position, requiring manual or additional auxiliary equipment to adjust the position of the casting components to match the casting requirements. This traditional structure has the following significant drawbacks: First, it lacks flexibility in adjusting the casting position, placing high demands on the casting workers' skill level; even slight deviations can lead to molten iron overflowing. Although some devices use external components to assist the casting process, the position of the casting mold still needs to be manually adjusted, resulting in low ease of use.

[0004] Therefore, there is an urgent need to develop a casting device with superior performance to solve the pain points in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a high-stability small compressor bearing housing casting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-stability small compressor bearing housing casting device includes a base, a portal frame fixedly connected above the base, a sliding support plate slidably connected to the base, an inclined groove opened on the portal frame, an inclined slide rod slidably connected in the inclined groove, and a casting component connected to the inclined slide rod. During the sliding of the inclined slide rod, the casting component moves away from or closer to the sliding support plate.

[0007] As a further embodiment of this utility model, a support foot is fixedly connected to the bottom of the base.

[0008] As a further embodiment of this utility model: a drive motor is fixedly connected to the bottom of the base, and an active bevel gear is fixedly connected to the output shaft of the drive motor. The sliding support plate is connected to the active bevel gear through a transmission assembly. When the active bevel gear rotates, the sliding support plate slides back and forth.

[0009] As a further embodiment of this utility model: the transmission assembly includes a longitudinal rotating shaft rotatably connected to the base, a driven bevel gear fixedly connected to the bottom of the longitudinal rotating shaft, a driving bevel gear meshing with the driven bevel gear, a drive rod fixedly connected to the eccentric part below the driven bevel gear, a grooved rod sleeved on the outside of the drive rod, a linkage rod fixedly connected to the grooved rod, a guide groove is provided on the base, and the end of the linkage rod passes through the guide groove and is fixedly connected to the sliding support plate.

[0010] As a further embodiment of this utility model: the top of the longitudinal rotating shaft is connected to a screw via a one-way coupling, a guide telescopic rod is fixedly connected to the inclined slide rod, a drive ring is fixedly connected to the end of the guide telescopic rod, and the drive ring is threadedly connected to the screw.

[0011] As a further embodiment of this utility model: the casting component includes a guide funnel fixedly connected to an inclined slide bar, and a screen is placed inside the guide funnel.

[0012] As a further improvement of this utility model: a reset wheel is fixedly connected to the outside of the screw, and a reset elastic rope is fixedly connected to the reset wheel. The other end of the reset elastic rope is fixedly connected to the base, and the reset elastic rope is always in a taut state.

[0013] As a further improvement of this utility model: a ratchet locking mechanism is provided on the top of the gantry frame. When the pawl of the ratchet locking mechanism disengages from the ratchet of the ratchet locking mechanism, the reset wheel resets.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is driven by a drive motor.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3A high-stability small compressor bearing housing casting device includes a base 1, a portal frame 2 fixedly connected above the base 1, a sliding support plate 3 slidably connected to the base 1, an inclined groove 4 on the portal frame 2, an inclined slide rod 5 slidably connected within the inclined groove 4, and a casting component 6 connected to the inclined slide rod 5. During the sliding of the inclined slide rod 5, the casting component 6 moves away from or closer to the sliding support plate 3. A support foot 7 is fixedly connected below the base 1, providing stable support for the entire device.

[0025] When using it, adjust the pouring position of the pouring component 6. After adjusting the pouring position, slide the sliding support plate 3 to adjust the position. The pouring mold at the top of the sliding support plate 3 can then be adjusted to be below the pouring component 6, so as to achieve pouring in conjunction with the pouring component 6.

[0026] Please see Figure 4 A drive motor 8 is fixedly connected to the bottom of the base 1. A drive bevel gear 9 is fixedly connected to the output shaft of the drive motor 8. The sliding support plate 3 is connected to the drive bevel gear 9 through a transmission assembly 10. When the drive bevel gear 9 rotates, the sliding support plate 3 slides back and forth. When the drive motor 8 rotates, it drives the drive bevel gear 9 to rotate. During the rotation of the drive bevel gear 9, the position of the sliding support plate 3 is adjusted through the transmission assembly 10.

[0027] The transmission assembly 10 includes a longitudinal rotating shaft 11 rotatably connected to the base 1. A driven bevel gear 12 is fixedly connected to the bottom of the longitudinal rotating shaft 11. A driving bevel gear 9 meshes with the driven bevel gear 12. A drive rod 13 is fixedly connected to the eccentric part below the driven bevel gear 12. A grooved rod 14 is sleeved on the outside of the drive rod 13. A linkage rod 15 is fixedly connected to the grooved rod 14. A guide groove 16 is provided on the base 1. The end of the linkage rod 15 passes through the guide groove 16 and is fixedly connected to the sliding support plate 3. The transmission assembly 10 can also adopt other transmission mechanisms, such as a crank-slider mechanism, to fix the sliding support plate 3 to the slider to achieve position adjustment.

[0028] During the adjustment process, the driven bevel gear 12 rotates synchronously with the rotation of the driving bevel gear 9, and drives the grooved rod 14 to slide synchronously back and forth through the drive rod 13. The grooved rod 14 will then drive the sliding support plate 3 to change position to achieve position adjustment.

[0029] The top of the longitudinal rotating shaft 11 is connected to a screw 17 via a one-way coupling. A guide telescopic rod 18 is fixedly connected to the inclined slide rod 5. A drive ring 19 is fixedly connected to the end of the guide telescopic rod 18. The drive ring 19 is threadedly connected to the screw 17.

[0030] Before adjusting the sliding support plate 3, the position of the casting component 6 needs to be adjusted first. When adjusting the position of the casting component 6, the drive motor 8 rotates in the opposite direction to the position of the sliding support plate 3. At this time, the drive motor 8 drives the screw 17 to rotate through the one-way coupling. The screw 17 drives the inclined slide bar 5 to slide along the inclined groove 4 through the drive ring 19, thereby adjusting the position of the casting component 6. During this process, the drive ring 19 moves up and down.

[0031] The casting assembly 6 includes a guide funnel 20 fixedly connected to the inclined slide bar 5, and a screen 21 is placed inside the guide funnel 20. The molten iron is screened through the ceramic screen 21, which has a porosity between 75-85%, and can filter out any fine impurities to ensure the purity of the molten iron and improve the overall quality of the product.

[0032] Example 2: Based on the previous example, this example also discloses the following technical features: a reset wheel 22 is fixedly connected to the outside of the screw 17, a reset elastic rope 23 is fixedly connected to the reset wheel 22, the other end of the reset elastic rope 23 is fixedly connected to the base 1, and the reset elastic rope 23 is always in a taut state.

[0033] After adjusting the pouring component 6, the reverse drive motor 8 is reversed to adjust the position of the sliding support plate 3. While adjusting the position of the pouring component 6, the reset wheel 22 drives the reset elastic rope 23 to wind around. After pouring is completed, the limit of the screw 17 is released to reset the pouring component 6. In this application, a ratchet locking mechanism 24 is used to lock and release the screw 17.

[0034] The top of the gantry frame 2 is provided with a ratchet locking mechanism 24. When the pawl of the ratchet locking mechanism 24 disengages from the ratchet of the ratchet locking mechanism 24, the reset wheel 22 resets.

[0035] As the screw 17 rotates, during the position adjustment of the casting component 6, the pawl of the ratchet locking mechanism 24 engages with the ratchet wheel of the ratchet locking mechanism 24, ensuring unidirectional transmission. When the position of the casting component 6 is adjusted to the appropriate range, the screw 17 will not rotate during casting due to the self-locking property of the thread, and the position of the casting component 6 can be locked. After the pawl is released, the ratchet locking mechanism 24 cannot lock, and under the reset force of the reset elastic rope 23, the casting component 6 moves upward to achieve reset. In this embodiment, the pawl is slidably connected to the gantry frame 2 and abuts against the ratchet surface under the spring force. When it is necessary to disengage the pawl from the ratchet, the pawl position is slid to disengage the pawl from the ratchet. In addition, the device can also limit and release the screw 17 through other structures. A limiting structure is set on the outside of the screw 17, which rotates when the screw 17 needs to rotate and locks the position when the screw 17 needs to be locked.

[0036] It should be noted that, in order to further ensure the quality of the castings, certain components in the molten iron material need to be controlled at the following levels to make the performance of the castings more stable. Specifically: C: 3.05-3.15%; Si: 1.7-2.0%; Mn: 1.0-1.2%; P: ≤0.05%; S: 0.05-0.12%.

[0037] Furthermore, the casting process of this application adopts a top-pouring riserless process, which utilizes the self-expansion and feeding of molten iron and a closed structure to improve the utilization rate of molten iron. This also makes the setting of the casting component 6 of this application necessary. Since the riserless process has more stringent requirements for the operator's operating skills, the casting component 6 disclosed in this application is specifically designed to avoid molten iron overflow.

[0038] Working principle: Position adjustment process: First, adjust the pouring position of the pouring component 6, then slide and adjust the sliding support plate 3 so that the top pouring mold is moved below the pouring component 6 to complete the pouring.

[0039] When the casting component 6 is adjusted, the drive motor 8 rotates and drives the screw 17 to rotate through the one-way coupling. The screw 17, with the help of the drive ring 19, causes the inclined slide bar 5 to slide along the inclined groove 4, thereby adjusting the position of the casting component 6.

[0040] After adjustment, the sliding support plate 3 can be adjusted by reversing the drive motor 8. At this time, due to the one-way coupling, the screw 17 does not rotate. The drive motor 8 rotates and drives the active bevel gear 9. Through the transmission component 10 (the driven bevel gear 12 rotates synchronously with the active bevel gear 9, and drives the grooved rod 14 to slide back and forth through the drive rod 13), the sliding support plate 3 is finally moved and adjusted.

[0041] When adjusting the pouring assembly 6, the reset wheel 22 drives the reset elastic rope 23 to wind around; after pouring is completed, the screw 17 is released from its limit (the screw 17 is locked and released using a ratchet locking mechanism 24), and the pouring assembly 6 can be reset. When adjusting the pouring assembly 6, the pawl of the ratchet locking mechanism 24 engages with the ratchet to achieve unidirectional transmission. During pouring, due to the self-locking of the threads, the screw 17 does not rotate, and the position of the pouring assembly 6 is locked; after releasing the pawl, the reset force of the reset elastic rope 23 drives the pouring assembly 6 to move upward and reset.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
