Technical Field

[0001] The utility model relates to the technical field of compressor housing manufacturing equipment, in particular to a compressor housing feeding mechanism. Background Art

[0002] In modern compressor manufacturing, the compressor housing, a core component, undergoes multiple critical processes, including stamping, casting, and machining. Material transfer between these processes, particularly the efficient and stable handling of irregularly shaped, semi-finished housings, has long been a significant bottleneck restricting production efficiency.

[0003] Traditionally, loading compressor casings relies primarily on manual labor. This method is not only inefficient and labor-intensive, but can also easily lead to problems such as uneven loading speed and unstable loading posture, which can affect subsequent automated assembly processes and even cause production line stalls. Furthermore, the haphazard nature of manual loading makes it difficult to ensure proper surface protection for the casing, increasing the risk of damage and scrap.

[0004] To address the shortcomings of manual loading, several automated loading mechanisms have been developed. However, existing automated loading mechanisms often suffer from complex structures, high maintenance costs, and limited versatility, making them difficult to adapt to compressor housings of varying sizes and shapes. These mechanisms typically employ complex mechanical structures and control systems, increasing manufacturing costs and failure rates. More importantly, many existing automated loading mechanisms fail to effectively maintain the housing's stable position and prevent damage during transport, creating potential quality risks. Utility Model Content

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0026] like Figures 1 to 5 As shown, the compressor housing loading mechanism described in this embodiment is mainly used to transport the compressor housing from a scattered state to the subsequent workstation in an orderly manner. The loading mechanism specifically includes:

[0027] The combing part 10 is used to send the compressor housing in a predetermined posture into the feeding guide rail 20; specifically, the combing part 10 is used to receive and sort the compressor housing in the incoming direction, so that it enters the feeding guide rail 20 in a predetermined posture and direction, and is ready for the subsequent feeding process; the feeding guide rail 20 includes a first inclined section 21 extending obliquely upward from the feeding end and a first straight section 22 extending horizontally toward the discharging end, and the first inclined section 21 is connected to the combing part 10; the circulating drive chain 30 is arranged below the feeding guide rail 20, and multiple equal-spaced sections are provided on its chain links. A follower rod 31 is provided, and the spacing between adjacent follower rods 31 is greater than the length of the compressor casing to be conveyed, so that a compressor casing to be conveyed can be accommodated between adjacent follower rods 31; wherein, an empty slot 40 extending along the first inclined section 21 and the first straight section 22 is provided on the loading guide rail 20, a part of the follower rod 31 extends from the empty slot 40 and abuts against the bottom of the compressor casing, and the follower rod 31 is configured to push the compressor casing to slide along the first inclined section 21 and the first straight section 22 under the drive of the circulating drive chain 30.

[0028] In actual work, the compressor casing is first preliminarily sorted by the combing part 10 to ensure that it enters the feeding guide rail 20 in a predetermined posture. Subsequently, the casing enters the inclined section 21 of the feeding guide rail 20 and reliably abuts against the follower rod 31 extending from the empty slot 40. Thereafter, when the circulating drive chain 30 starts to operate, the follower rod 31 will continue to push the compressor casing to slide along the inclined section 21 and the horizontal section 22 of the feeding guide rail 20, and finally transport it smoothly to the designated position. In particular, the follower rod 31 does not directly push the casing, but only contacts the empty bottom of the compressor casing. This design allows the casing to slide smoothly on the guide rail instead of being directly pushed to move, reducing the risk of damage to the casing's appearance and improving the smoothness of the transportation process. When the compressor casing is transported to the end of the horizontal section 22, it can be conveniently picked up by subsequent workstations, such as using a pneumatic suction cup, to perform processes such as deburring, thereby achieving seamless connection between loading and subsequent processing and improving overall production efficiency.

[0029] In some embodiments, as Figure 1 、 Figure 3 As shown, a first connecting plate 32 extending horizontally outward is fixed on the chain link of the circulating drive chain 30, and a second connecting plate 33 is provided at the bottom end of the follower rod 31. The first connecting plate 32 and the second connecting plate 33 are each provided with at least two threaded holes along the length direction of the chain link, and the first connecting plate 32 and the second connecting plate 33 are fixed by threading by passing bolts through the threaded holes.

[0030] In this embodiment, this bolt connection method not only makes the installation and removal of the follower rod 31 very convenient, without the need for complex tools, but also provides the possibility of adjusting the position of the follower rod 31. For example, when it is necessary to transport a different compressor housing, the adjustment can be completed by simply loosening the bolts, selecting the threaded hole on the appropriate chain link, and retightening the bolts. This feature facilitates the rapid switching of the production line according to different compressor housing sizes or shapes, improving the flexibility and adaptability of the production line. In addition, because this structure uses common bolt connections, its manufacturing cost is low and maintenance is more convenient and quick. It also ensures that the follower rod 31 will not loosen or fall off when the circulating drive chain 30 operates at high speeds, ensuring the stability and reliability of the feeding mechanism.

[0031] In some embodiments, as Figure 2 As shown, guide edges 23 are detachably mounted on both sides of the first inclined section 21 and the first straight section 22, and the distance between the two guide edges 23 is adapted to the width of the compressor housing. With this structural design, after the compressor housing enters the loading guide rail 20, its lateral movement will be restricted by the guide edges 23 on both sides, ensuring that the housing always remains on the predetermined track during the transportation process and will not deviate or tilt. In particular, the detachable guide edges 23 can be adjusted to the installation position of the guide edges 23 so that the loading mechanism can adapt to compressor housings of different widths. This means that even when different types of compressor housings need to be transported, there is no need to frequently replace or adjust the loading mechanism. Different transportation requirements can be met by simply adjusting the distance between the guide edges 23.

[0032] In some embodiments, a silicone sleeve is provided on the follower rod 31. The silicone sleeve is soft and can effectively cushion the contact impact between the follower rod 31 and the compressor housing, preventing damage such as scratches, scrapes, or bumps on the housing surface caused by hard contact during transportation.

[0033] In some embodiments, as Figure 1 、 Figure 4 As shown, it also includes a compression shell arc plate 50, which is arranged above the first straight section 22, and one end of the compression shell arc plate 50 facing the first inclined section 21 is pivotally connected to the external support structure; when the follower rod 31 on the circulating drive chain 30 drives the compressor casing to run to the first straight section 22, the other end of the compression shell arc plate 50 is crimped onto the compressor casing that has been detached from the follower rod 31.

[0034] During specific implementation, the compression shell arc plate 50 is not fixed, but one end of the compression shell arc plate 50 facing the first inclined section 21 is pivotally connected to the external support structure through a pivot structure. When the follower rod 31 on the circulating drive chain 30 pushes the compressor housing to run to the first straight section 22, it may jump or flip due to inertia. At this time, the other end of the compression shell arc plate 50 will be pressed onto the compressor housing that has been separated from the follower rod 31, thereby effectively suppressing the jumping and flipping of the housing. This allows the compressor housing to be more smoothly transported to the subsequent workstation, providing reliable protection for subsequent processes. It is particularly important to point out that the compression shell arc plate 50 is pressed against the housing after the housing is separated from the follower rod 31, which ensures that the compression shell arc plate 50 will not interfere with the pushing effect of the follower rod 31 on the housing, thereby ensuring the reliability and accuracy of transportation.

[0035] In some embodiments, as Figure 1 As shown, the combing portion 10 includes a second straight section 11, a second inclined section 12 and a third straight section 13. The second inclined section 12 extends obliquely downward and is connected between the second straight section 11 and the third straight section 13. The third straight section 13 is connected to the feed end of the first inclined section 21. The widths of the second straight section 11, the second inclined section 12 and the third straight section 13 are adapted to the width of the compressor housing.

[0036] In specific implementation, the compressor housing can be placed manually or transported to the combing section 10 via a conveyor belt. First, the housing enters the second straight section 11 of the combing section 10. The function of this section is to initially receive and guide the housing into the combing path. Subsequently, under the action of gravity, the housing will naturally slide down along the second inclined section 12 extending obliquely downward, and gradually adjust its posture, and finally smoothly enter the third straight section 13. In the third straight section 13, the housing will smoothly enter the first inclined section 21 of the feeding guide rail 20 with the help of inertia in a stable posture and direction, and reliably abut against the follower rod 31, thereby being driven by the follower rod 31. In addition, in order to ensure that the housing can be transported smoothly and accurately in the combing section 10, the widths of the second straight section 11, the second inclined section 12, and the third straight section 13 are all designed to precisely match the width of the compressor housing, thereby effectively preventing the housing from lateral displacement or jamming during the combing process, thereby ensuring the smoothness and reliability of the combing process.

[0037] In some embodiments, as Figure 1As shown, smooth rounded corners transition between the second straight section 11 and the second inclined section 12, between the second inclined section 12 and the third straight section 13, and between the third straight section 13 and the first inclined section 21. The rounded corners prevent the impact force generated by sharp corner collisions when the compressor housing moves between guide sections, thereby reducing the risk of damage to the housing. The smooth rounded corners also allow for smoother transitions between guide sections, reducing potential jams or stagnation caused by sharp corners, and improving the fluidity and continuity of delivery.

[0038] In some embodiments, as Figure 1 、 Figure 5 As shown, one end of the second straight section 11 is connected to a shell supply vibration plate 14. Specifically, when the compressor shells enter the combing section 10 by manual delivery or conveyor belt, they are often in a disorderly manner. At this time, the vibration generated by the shell supply vibration plate 14 can effectively comb these scattered shells, so that they are gradually arranged in an orderly manner under the action of vibration and enter the second straight section 11 in a suitable posture; at the same time, the vibration of the shell supply vibration plate 14 can effectively prevent the shells from piling up and clogging at the entrance of the second straight section 11, thereby ensuring that the shells can continuously and evenly enter the combing mechanism, providing a stable material supply guarantee for the subsequent feeding process.

[0039] The compressor casing feeding mechanism provided in this embodiment, through the inclined guide rail design and the follower rod drive, not only significantly improves the feeding efficiency and realizes the rapid and continuous conveying of the casing, but also effectively improves the stability of the conveying process and avoids the common jamming and tipping phenomena in traditional feeding mechanisms. The mechanism has a simple structure and is easy to maintain and repair, which greatly reduces maintenance costs and downtime. At the same time, the mechanism can effectively protect the casing during the conveying process, avoiding bumps and scratches, thereby reducing the scrap rate and improving product quality. In addition, the mechanism realizes the automation of the feeding process, greatly reduces manual intervention, and effectively reduces labor costs. More importantly, the mechanism has good versatility and can be flexibly applied to compressor casings of different sizes and shapes without the need for frequent equipment replacement, which significantly improves the automation level and overall production efficiency of compressor manufacturing.
