Abstract
Description
Technical Field
[0001] This utility model belongs to the field of compressor steel sleeve production, and in particular relates to a product feeding and turning conveyor device. Background Technology
[0002] As a core component of reciprocating compressors, the compressor sleeve's design and manufacturing technology directly affect the overall efficiency, reliability, and lifespan of the machine. Its core function is to form a sealed compression chamber with the piston and piston rings, bearing the high pressure and high temperature generated during gas compression and guiding the piston in high-speed reciprocating motion. In the continuous production process of compressor sleeves, the transfer of sleeves between production stages faces numerous challenges. Traditional feeding and conveying devices often use external clamping or lifting methods to transfer compressor sleeves. For annular, tubular, or special compressor sleeves with inner ring structures, external clamping can easily lead to surface deformation, scratches, or damage to precision. Lifting conveyors, on the other hand, are difficult to adapt to compressors with irregular shapes. The steel sleeve has poor stability and is prone to slippage. Manual transfer is not only inefficient but also labor-intensive and prone to errors, making it difficult to meet the cycle time requirements of automated production lines. In addition, some production processes require the compressor steel sleeve to be flipped to adapt to downstream processing needs. Traditional devices require additional flipping equipment, which not only increases the space occupied on the production line but may also reduce transfer efficiency due to poor equipment connection, or even cause secondary damage to the compressor steel sleeve. These problems make traditional conveying devices significantly inadequate in adapting to compressor steel sleeves with special structures, ensuring transfer stability, improving automation, and meeting the needs of multi-process collaboration. There are also connection problems between two adjacent processes. Utility Model Content

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0025] like Figure 1 As shown, the product unloading and turning conveyor includes a support beam 1, a conveying assembly 2, a turning assembly 3, and an inner clamping assembly 4. The conveying assembly 2 is slidably connected to the periphery of the support beam 1, and the support beam 1 is fixedly installed in a fixed position. The turning assembly 3 is provided at the lower end of the conveying assembly 2, and the inner clamping assembly 4 is installed on the turning assembly 3. The inner clamping assembly 4 is used to pick up and clamp the product to be turned from the upstream line. The turning assembly 3 is used to drive the inner clamping assembly 4 and the product to be turned to turn. The conveying assembly 2 is used to convey the turned product to the downstream line. In this embodiment, the product to be turned is the outer steel sleeve of an air conditioner compressor. Figure 2 As shown, the conveying assembly 2 includes a frame 21, two tracks 22, and a drive unit 23. Two parallel tracks 22 are provided on the upper end of the support beam 1. The movable ends of the drive unit 23 are rotatably connected to the periphery of each track 22. The drive unit 23 is fixedly installed inside the frame 21, and the inner wall of the frame 21 is slidably connected to the periphery of the support beam 1. When the servo motor 232 starts, its output shaft drives the wheel axle 231 fixedly connected to it to rotate. Rollers 233, with fixed sleeves at both ends, roll within the two parallel tracks 22 on the upper end of the frame 21. The two inner walls of the drive unit 23 are slidably connected to the periphery of the frame 21. The rolling of the rollers 233 drives the drive unit 23 to move along the frame 21, causing the entire conveying assembly 2 to slide along the support beam 1, thereby realizing the transport of the compressor steel sleeve. The conveying assembly 2, after clamping the compressor steel sleeve, can transport it to the next process, playing a connecting role between multiple processes, ensuring continuous production, and improving production efficiency.
[0026] like Figure 3As shown, the drive unit 23 includes two axles 231, a servo motor 232, and rollers 233. Two parallel axles 231 are rotatably connected inside the frame 21. A roller 233 is fixedly sleeved on the outer periphery of each end of the axle 231. The outer periphery of each roller 233 is correspondingly tumbling connected to the outer periphery of a track 22. The servo motor 232 is installed on the upper end of the frame 21. The output shaft of the servo motor 232 is fixedly connected to one end of any axle 231. The servo motor 232 is existing technology, and its model is BLDC50WAGV.
[0027] like Figure 4 As shown, the flipping assembly 3 includes two support plates 31, a bracket 32, a U-shaped frame 33, and a linear module 34. The bracket 32 is installed at the lower end of the frame 21. Two support plates 31 are installed on the inner side of the bracket 32. The two support plates 31 are arranged axially symmetrically. Each support plate 31 has a sliding groove on its outer side. One inner sidewall of the opening end of the U-shaped frame 33 is slidably connected in each sliding groove. The other end of the U-shaped frame 33 is connected to the movable end of the linear module 34. The fixed end of the linear module 34 is installed in the bracket 32. The linear module 34 is a telescopic cylinder, linear motor, or lead screw of the prior art. In this embodiment, the linear module 34 is a telescopic cylinder.
[0028] like Figure 5 and Figure 6 As shown, the flipping assembly 3 also includes a first rotating shaft 35, a second rotating shaft 36, and a rotating component 37. The rotating component 37 is rotatably connected between the two support plates 31 via the first rotating shaft 35. One end of the rotating component 37 has a through hole, and the second rotating shaft 36 is slidably connected within the through hole. The second rotating shaft 36 is rotatably positioned at the open end of the U-shaped frame 33. The outer periphery of the second rotating shaft 36 is slidably connected within the two support plates 31. The movable end of the linear module 34 drives the U-shaped frame 33 to move. The inner sidewall of the open end of the U-shaped frame 33 slides within the groove on the outer side of the two support plates 31. Simultaneously, the second rotating shaft 36 at the open end of the U-shaped frame 33 moves accordingly. The second rotating shaft 36 slides within the through hole of the rotating component 37, causing the rotating component 37 to rotate around the first rotating shaft 35 between the two support plates 31. The rotation of the rotating component 37 drives the connected inner clamping assembly 4. The compressor steel sleeve is flipped, and the flipping component 3 is set up to flip the compressor steel sleeve 90 degrees, adjusting the compressor steel sleeve to a suitable angle to facilitate the connection of subsequent processes and ensure the smoothness of the overall production.
[0029] like Figure 7As shown, the inner clamping assembly 4 includes a telescopic cylinder 41 and an inner expansion shaft 42. One end of the rotating component 37 is connected to the fixed end of the telescopic cylinder 41, and the movable end of the telescopic cylinder 41 is connected to the inner expansion shaft 42. One end of the inner expansion shaft 42 is fixedly connected to one end of the rotating component 37. A distance sensor 371 is also provided on the rotating component 37. The distance sensor 371 is used to detect the distance between the rotating component 37 and the compressor cylinder liner. The distance sensor 371 is existing technology, and the model of the distance sensor 371 is VDM54.
[0030] The distance at which the compressor sleeve is precisely aligned with the inner expansion shaft 42 is determined. When the distance between the rotating component 37 and the compressor cylinder sleeve is exactly the set value, it indicates that the compressor sleeve is precisely fitted around the inner expansion shaft 42. The controller then drives the subsequent inner expansion clamping and conveying flipping operations. If the distance between the rotating component 37 and the compressor cylinder sleeve is not the set value, the controller will control the conveying component 2 to approach or move away from the compressor sleeve until the set value is found. If the distance between the rotating component 37 and the compressor cylinder sleeve is infinite, it indicates that the compressor cylinder sleeve has not been detected, and the device needs to be stopped and manually calibrated. After the setting is complete, the distance between the compressor sleeve and the rotating component 37 should first decrease within a certain range, indicating that when the conveying component 2 approaches the compressor sleeve and transports it to a specific distance, the compressor sleeve is precisely fitted around the inner expansion shaft 42. The inner expansion shaft 42 expands and clamps the inner ring of the compressor sleeve. After a period of time, the inner expansion shaft 42 contracts, removing the compressor sleeve. At this time, the distance will increase within a certain range. After removal, the entire device resets, and the above process is repeated.
[0031] like Figure 8 and Figure 9 As shown, the internal expansion shaft 42 includes a shaft 421, a bushing 422, two sets of movable units 423, a shaft plate 424, and a pressure sensor 425. The movable end of the telescopic cylinder 41 is fixedly connected to one end of the shaft 421. Two sets of movable units 423 are fixedly sleeved around the outer periphery of the shaft 421. The two sets of movable units 423 are arranged parallel to each other. The inner ring of a shaft plate 424 is fixedly connected to each side of the movable unit 423. The two shaft plates 424 are arranged opposite to each other. The outer periphery of the shaft plate 424 is used to abut against the inner ring of the product. One end of the shaft plate 424 is slidably connected to one end of the bushing 422. The other end of the bushing 422 is fixedly connected to the lower end of the rotating part 37. The pressure sensor 425 is arranged around one of the shaft plates 424. The pressure sensor 425 is existing technology. The model of the pressure sensor 425 is Rohe D2632. When the inner expansion shaft 42 expands in the inner ring of the compressor steel sleeve, the shaft plate 424 will abut against the inner ring of the compressor steel sleeve and trigger the pressure sensor 425 to transmit the signal to the controller. After the controller knows that it has been clamped, it will enter the subsequent moving and flipping process.
[0032] like Figure 9As shown, each shaft piece 424 has a slide table 4241 at its upper end and two slide grooves 4221 at its lower end. Each slide table 4241 is slidably connected to a corresponding slide groove 4221.
[0033] like Figure 10 and 11 As shown, the active unit 423 includes two first sliding members 4231, two second sliding members 4232, and a metal ring 4233. The metal ring 4233 is fixedly sleeved around the shaft 421. The outer periphery of the metal ring 4233 is fixedly connected to the planar ends of the two first sliding members 4231 respectively. The two first sliding members 4231 are arranged opposite to each other. The inclined end of each first sliding member 4231 is slidably connected to the inclined end of a second sliding member 4232. The planar end of each second sliding member 4233 is fixedly connected to the inner ring of a corresponding shaft piece 424. The movable end of the telescopic cylinder 41 drives the shaft 421 to move. The shaft 421 drives the two sets of movable units 423, which are fixedly sleeved on the outside, to move synchronously. The first sliding member 4231 on both sides of the metal ring 4233 moves with the shaft 421. The inclined end slides relative to the inclined end of the second sliding member 4232. The second sliding member 4232 moves outward under the thrust, causing the shaft piece 424 fixedly connected to it to open. One end of the shaft piece 424 slides along the bushing 422, and its outer periphery abuts against the inner ring of the compressor steel sleeve to achieve clamping. The telescopic cylinder 41 retracts, the shaft piece 424 retracts, and the compressor steel sleeve is released. An inner clamping component 4 is provided, which uses the inclined sliding principle to adjust the opening range of the shaft piece. It can be adapted to compressor steel sleeves with different inner diameters, enhancing the versatility of the device. Moreover, it clamps from the inner ring of the compressor steel sleeve, avoiding contact with the outer surface of the compressor steel sleeve and preventing damage and wear to the outer surface of the compressor steel sleeve.
[0034] Working process of the product unloading and tilting conveyor device: The device is used for transferring compressor sleeves between two production processes. The linear module 34 of the flipping assembly 3 pushes the U-shaped frame 33 to slide along the slide groove of the support plate 31. The second rotating shaft 36 slides in the through hole of the rotating part 37. At the same time, the rotating part 37 rotates around the first rotating shaft 35 to flip the compressor sleeve. When the compressor sleeve reaches the designated position, the distance sensor 371 on the rotating part 37 detects the position of the compressor sleeve. The telescopic cylinder 41 extends and pushes the shaft 421 to move. The shaft 421 drives the two sets of moving units 423 to move. The first sliding part 423... The inclined surface of the first sliding member 4232 slides, causing the shaft piece 424 to expand outward along the bushing 422, abutting against and clamping the compressor steel sleeve from the inner ring of the compressor steel sleeve. The pressure sensor 425 determines that the shaft piece 424 has completely abutted against the inner ring of the compressor steel sleeve. The servo motor 232 drives the wheel axle 231 to rotate, causing the roller 233 to roll in the track 22, so that the conveying component 2 slides along the support beam 1, transporting the compressor steel sleeve to the target position. The telescopic cylinder 41 retracts, and the shaft piece 424 retracts inward to release the compressor steel sleeve, completing the transfer.
[0035] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
