Description

Technical Field

[0001] The utility model relates to the field of compressor production tooling, and particularly relates to a turnover device for compressor shells. Background Art

[0002] At present, piston-type refrigerator compressors are enclosed, and the upper shell of the compressor and the lower shell of the compressor are welded together by a welding torch to ensure the sealing performance of the compressor. During mass production, the lower shell, feet, sealed terminal, relay bracket, and three pipes (suction pipe, process pipe, exhaust pipe) need to be welded together in sequence in the stamping and welding workshop to form a lower shell component. Then, the welded lower shell component is placed in an iron frame. After it is full, a forklift is used to transport the iron frame filled with the lower shell components to the assembly workshop for the next assembly work. During the process of loading the iron frame, the lower shell components come into contact with each other, and during this process, it is easy to cause the sealed terminal to collide with other shells. The sealed terminal is mainly composed of a glass body and a guide post. After the collision, the glass body is broken, resulting in poor insulation withstand voltage of the compressor and easily leading to safety accidents.

[0003] A turnover cart for cylinder blanks of an automotive air-conditioning compressor is disclosed in a Chinese patent (publication number CN205440464U). The base is in an I shape, and the end of a vertical bar is respectively connected to the middle parts of two horizontal bars to form an I shape. Universal wheels are arranged at the bottom ends of the two horizontal bars; two vertical support bars are vertically connected to the middle parts of the two horizontal bars, and several horizontal support bars are fixedly connected to the two vertical support bars at equal intervals from top to bottom; several hooks are arranged at equal intervals from left to right on both sides of the horizontal support bars. It stores the cylinder blanks of the compressor in a single-point hanging manner. During its movement, the cylinder blanks are still prone to shaking, resulting in mutual collision of the cylinder blanks, and it is difficult to be applicable to the turnover process of the compressor shell. At the same time, during production, due to factors such as process offline, it is impossible to make the number of shells and the number of cores exactly the same. Therefore, there will be a certain inventory of lower shell components. When there are many types of inventory, it is relatively difficult to control the placement position and identification. Content of the Utility Model

[0004] The purpose of the utility model is to address the defects existing in the prior art and provide a turnover device for compressor shells. Hanging racks arranged in an array are provided on the turnover cart. The hanging rack is composed of a pair of oppositely arranged hanging rods. Lifting platforms are respectively formed on the two hanging rods of the same hanging rack to carry the shells suspended upside down. The feet of the shell can form surface-to-surface contact with the lifting platform, which is convenient for maintaining the position of the shell and can make the vulnerable glass body be on the side of the shell. Even if the shells on the same hanging rack collide due to disturbance, the collision position avoids the vulnerable components, ensuring the integrity of the shell during turnover.

[0026] In a typical embodiment of the present invention, as Figures 1 - 4 shown, a compressor housing turnover device is proposed.

[0027] If the compressor housing 1 is temporarily stored in a single-point hanging manner, during its movement, the housing 1 is still prone to shaking, resulting in mutual collision of the cylinder blanks, and it is difficult to be applicable to the turnover process of the compressor housing 1. Based on this, the present embodiment provides a compressor housing turnover device, which consists of a turnover cart 2 and a plurality of hanging frames. The turnover cart 2 serves as a basic platform for supporting and moving the entire device. The hanging frames are fixed on the turnover cart 2 and arranged in an array distribution form. Each hanging frame is designed to be able to safely and stably hang the compressor housing 1, reduce the collision between the housings 1, carry the housing 1 in a longitudinal arrangement manner, and make the vulnerable parts on the housing 1 be on the side, so as to provide good protection for the vulnerable parts during the turnover process of the housing 1.

[0028] As Figure 1 shown, the compressor housing turnover device includes a turnover cart 2 and hanging frames arranged on the turnover cart 2. A plurality of hanging frames are arranged in an array distribution on the turnover cart 2, and adjacent hanging frames are spaced apart. The hanging frames can carry the housing 1. In this embodiment, as Figure 4 shown, the housing 1 carried by the hanging frame is the lower housing 1-5 component of the compressor housing 1. The feet 1-4, the sealed terminal 1-7, the relay bracket 1-6, the suction pipe 1-1, the process pipe 1-2, and the exhaust pipe 1-3 are respectively welded to the lower housing 1-5 to form the lower housing 1-5 component. Among them, the sealed terminal 1-7 is mainly composed of a glass body and a guide post. After collision, the glass body is broken, resulting in poor insulation withstand voltage of the compressor. Therefore, in this embodiment, the housing 1 is kept at intervals from other housings 1 both vertically, longitudinally and horizontally, so as to reduce the collision between the housings 1 during the transportation process.

[0029] Each hanging frame is composed of a pair of parallel and spaced hanging rods. On one side of the hanging rod of the same hanging frame facing the different hanging rod, there is a platform 2-2 distributed along the axial direction of the hanging rod. The platforms 2-2 of the two hanging rods on the same hanging frame overlap and carry the feet 1-4 of the same housing 1, so that the housing 1 is suspended and arranged in an inverted posture.

[0030] When arranging the housing 1, the main body of the lower housing 1-5 is located between the two hanging rods of the same hanging frame, and the feet 1-4 welded on the lower housing 1-5 overlap with the hanging rods. In this posture, the sealed terminal 1-7 is on the side of the gap between the two hanging rods and below the hanging rods, and the multiple housings 1 arranged on the same hanging frame are distributed along the axial direction of the hanging rods, so that the sealed terminal 1-7 avoids the vulnerable collision position. It ensures the structural stability of the hanging frame and provides enough space to hang the housing 1, avoiding mutual interference between the housings 1.

[0031] On one side of the hanging rod facing the different hanging rod, there is a platform 2-2 distributed along the axial direction of the hanging rod. The platform 2-2 is a key part of the hanging rack. It directly contacts the feet 1-4 of the compressor housing 1 to ensure that the housing 1 can be stably suspended in an inverted posture. The design of the platform 2-2 enables the feet 1-4 of the housing 1 to form a surface-to-surface contact with it, thus effectively preventing the housing 1 from shaking or falling off during the turnover process. By hanging the housing 1 in an inverted manner, the vulnerable parts such as the glass body are located on the side of the housing 1, rather than in positions such as between adjacent housings 1 on the same hanging rack that are prone to being impacted, reducing the risk of damage to the housing 1 due to collision during the turnover process.

[0032] The hanging racks are distributed in an array on the turnover cart 2, enabling the entire device to accommodate a large number of compressor housings 1, improving the turnover efficiency. A certain interval is maintained between adjacent hanging racks, ensuring the independence of the hanging racks, avoiding interference with each other, and facilitating the operator to pick up, place, and inspect during the turnover process.

[0033] Through the surface-to-surface contact design between the platform 2-2 and the feet 1-4 of the housing 1, the stability of the housing 1 during the turnover process is ensured, preventing the housing 1 from shaking and falling off. The design of hanging in an inverted manner places the vulnerable parts such as the glass body on the side of the housing 1, effectively avoiding damage caused by collision. The design of the array-distributed hanging racks increases the capacity of the entire device, enabling more compressor housings 1 to be turned over simultaneously, improving the working efficiency.

[0034] As Figure 2 and Figure 3 shown, the vehicle frame 2-1 serves as the basic support structure of the entire turnover device. The vehicle frame 2-1 adopts a frame structure, which not only ensures strength but also reduces weight. This enables the vehicle frame 2-1 to bear the weight of the hanging racks and the compressor housing 1 and maintain overall stability. The universal wheels 2-3 are installed at the corner positions at the bottom of the vehicle frame 2-1, with at least three provided to ensure that the turnover cart 2 can move stably, enabling the turnover cart 2 to move flexibly in different directions and on different grounds, improving the convenience of operation. At the same time, the setting of the brake pedal allows the operator to lock or unlock the universal wheels 2-3 at any time to ensure that the turnover cart 2 can be fixed when needed.

[0035] The hanging rod is made of an angle steel with an L-shaped cross-section, providing sufficient strength. The angle steel is composed of a first limb and a second limb connected at the end. The planes where the first limb and the second limb are located are perpendicular, and the shape characteristics of the hanging rod are used to form the platform 2-2. The first limb is horizontally arranged as the platform 2-2, directly bearing the feet 1-4 of the compressor housing 1; the second limb connects the first limb and is fixed to the turnover cart 2, playing a supporting and stabilizing role.

[0036] The first limbs of the two hanging rods on the same hanging rack (i.e., the part of the platform 2-2) are coplanarly distributed, ensuring that the two platforms 2-2 can carry the two feet 1-4 of the same housing 1 simultaneously and stably, improving the stability of the housing 1.

[0037] The hanging rods are fixed to the turnover cart 2 through auxiliary blocks. The auxiliary blocks can adopt structures such as connecting pieces, connecting rods, and square tubes, making the installation of the hanging rack more firm and reliable, and also enabling the distance between the two hanging rods on the same hanging rack to meet the required specifications. At the same time, a protective layer is provided on the platform 2-2 for contacting the feet 1-4 of the housing 1, which can adopt structures such as plastic plates and rubber plates to reduce wear and scratches on the feet 1-4 and protect the integrity of the housing 1.

[0038] The hanging racks are arranged in a rectangular array on the turnover cart 2, which can maximize the use of the space of the turnover cart 2. At the same time, in the first direction and the second direction of the rectangular array, there are gaps between the housings 1 carried by adjacent hanging racks, avoiding direct contact and collision between the housings 1 carried on different skeletons and protecting the surface of the housing 1 from damage.

[0039] In the axial direction of the hanging rod, a plurality of load-bearing parts are formed on the platform 2-2 at intervals, and the hanging rack can carry multiple compressor housings 1 simultaneously. At the same time, one or more hanging racks can be adjusted to different sizes from other hanging racks to adapt to housings 1 of different sizes, improving the flexibility and adaptability of the turnover cart 2.

[0040] A plurality of card slots are provided on the turnover cart 2 for placing identification stickers. This facilitates the operator to classify, number, or mark the compressor housings 1, improving the convenience and accuracy of management. The card slots are distributed at both axial ends of the hanging rod and correspond to the position of the hanging rack. The identification stickers can be observed from both sides, and the identification stickers can directly correspond to the specific hanging rack and housing 1, reducing the possibility of confusion and errors. Through the design of the card slots and identification stickers, the classification, numbering, and management work of the compressor housings 1 are simplified. The rationality and humanized consideration of the overall design enable the operator to complete the work more easily and efficiently during the turnover process.

[0041] In this embodiment, the compressor housing turnover device is mainly applied to the turnover and placement of the lower shell 1-5 components.

[0042] First, the welded housings 1 are placed according to their respective models, as Figure 1 shown, and are slid onto the platform 2-2 of the turnover cart 2 in sequence; even if two housings 1 collide, vulnerable parts such as the suction pipe 1-1, process pipe 1-2, exhaust pipe 1-3, and sealed terminal 1-7 will not be damaged;

[0043] Then, after the placement of this model is completed, the identification card is posted at a fixed position on the vehicle frame 2-1 for easy distinction;

[0044] Finally, after the transfer cart 2 is filled with the housing 1, push the transfer cart 2 to the next process or push the transfer cart 2 to the designated area.

[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
