Description

Technical Field

[0001] The present invention relates to the technical field of air compressor assembly, and in particular to automated assembly equipment for air compressor production and an operating method thereof. Background Art

[0002] An air compressor is a device used to compress gas, including a twin-screw air compressor. A twin-screw compressor is a double-shaft positive displacement rotary compressor, which mainly compresses air by the rotation of the main and auxiliary rotor screws. In the actual assembly process, it is necessary to avoid bumping and damaging the coatings of the main and auxiliary rotor screws, and at the same time, it is necessary to ensure that the clearance between the main and auxiliary rotors meets the standard, otherwise it will affect the quality of air compression. At present, the automatic assembly equipment for air compressors mostly uses a sling to hang the rotor screws and insert them into the air compressor housing one by one. After the main rotor is inserted into the air compressor housing, the auxiliary rotor needs to be inserted in a spiral rotation state when installing. Improper operation may easily bump against the main rotor and the air compressor housing, making it inconvenient for the main and auxiliary rotors to be inserted into the air compressor housing after automatic assembly. The installation is not efficient enough, and the installation accuracy is poor. It is also inconvenient to perform accuracy testing on the main and auxiliary rotor screws after installation. The rotor axial clearance control effect is poor, which may easily cause poor performance of the air compressor after assembly.

At the same time, the overall structure is labor-saving and convenient to use manually, and has better safety. ;

[0042] An operating method of an automated assembly device for air compressor production, the steps comprising:

[0043] 1) Place the air compressor housing between the two limit bars 105, manually control the start of the conveying motor 103 to drive the roller 102 to rotate, and drive the conveyor belt 104 to convey the air compressor housing; manually control the centering hydraulic cylinder 106 to drive the positioning plate 107 to push the air compressor housing against the end of the guide positioning piece 402 for positioning;

[0044] 2) The main and auxiliary rotor screws are placed on the support mounting plate 201, and the clamping drive hydraulic cylinder 302 is manually controlled to drive the two drive brackets 301 to move toward each other, driving the two driving wheels 602 and the driven wheel 603 to move toward each other, clamping the main and auxiliary rotor screws, and the limit drive cylinder 501 is manually controlled to push out the plug-in column 502 and insert it into the main and auxiliary rotor screws. The drive motor 601 is controlled to drive the driving wheel 602 to rotate, driving the main and auxiliary rotor screws to rotate at the same time. At this time, the plug-in column 502 is inserted into the thread of the main and auxiliary rotor screws. Under the rotation and extrusion of the thread, the main and auxiliary rotor screws will produce axial displacement on the driving wheel 602 and the driven wheel 603, and are inserted into the air compressor housing for assembly;

[0045] 3) After the rotor screw is driven to be inserted into the air compressor housing, the electric screw 701 is manually controlled to drive the movable slider 702 to move, driving the two detection balls 802 on the swing arm 801 to fit and squeeze the ends of the main and auxiliary rotor screws; the pressure data displayed by the pressure sensor digital display module 202 is manually observed to see if there is any deviation from the basic value.

[0046] The working principle of this embodiment is as follows: first, place the entire device on the ground, place the air compressor housing between the two limit bars 105, use the limit bars 105 to limit, place the main and auxiliary rotor screws on the support mounting plate 201, and drive the roller 102 to rotate through the conveying motor 103, so as to drive the conveyor belt 104 to transport the air compressor housing. When the air compressor housing moves to the position of the support mounting plate 201, control the centering hydraulic cylinder 106 to drive the positioning plate 107 to move, and use the inner inclined surface structure of the positioning plate 107 to realize the centering and pushing of the air compressor housing so that it is close to the end of the guide positioning piece 402 for positioning, so as to ensure smooth subsequent installation. At the same time, the two clamping drive hydraulic cylinders 302 drive the two drive brackets 301 When moving toward each other, the two driving wheels 602 and the driven wheel 603 can be driven to move in opposite directions to clamp the main and auxiliary rotor screws, and make their threads mesh and fit together to ensure installation accuracy. When the two driving brackets 301 move toward each other, the positioning clamping plate 401 and the guide positioning piece 402 are driven to move simultaneously. At this time, the two guide positioning pieces 402 are respectively aligned with the ports of the air compressor housing. At the same time, the two main and auxiliary rotor screws are clamped by the driving wheel 602 and the driven wheel 603. During the process, the main and auxiliary rotor screws mesh closely with each other. When the main and auxiliary rotor screws need to be installed, the plug-in column 502 is pushed out through the limit driving cylinder 501, so that the end of the plug-in column 502 is inserted into the inner side of the thread of the main and auxiliary rotor screws, and cooperates with the driving cylinder 501 to drive the plug-in column 502 ... The motor 601 drives the driving wheel 602 to rotate, driving the main and auxiliary rotor screws to rotate at the same time. At this time, the plug-in column 502 is inserted into the thread of the main and auxiliary rotor screws. Under the rotation and extrusion of the thread, the main and auxiliary rotor screws will produce axial displacement on the driving wheel 602 and the driven wheel 603. At this time, the main and auxiliary rotor screws will be respectively attached to the inner sides of the two guide positioning pieces 402, and inserted into the air compressor housing in a spiral shape for assembly; after the main and auxiliary rotor screws are driven to be inserted into the air compressor housing, the electric screw 701 is manually controlled to drive the moving slider 702 to move, driving the two detection balls 802 on the swing arm 801 to fit and squeeze the main and auxiliary rotor screws, apply pressure, and cooperate with the tension springs 7021 on both sides of the swing arm 801 to elastically pull the main The auxiliary rotor screw is fully inserted into the air compressor housing. If the ends of the main and auxiliary rotor screws are not flush at this time, the swing arm 801 will fit the ends of the main and auxiliary rotor screws under the drive of the movable slider 702. However, the swing arm 801 will be skewed at this time, and the swing rod 803 on the swing arm 801 is no longer coaxial with the sliding column 708, but rotates to squeeze the sliding column 708, driving the sliding column 708 to retract. The retraction of the sliding column 708 squeezes the pressure sensor 707, and the pressure data is displayed through the pressure sensor digital display module 202. The value is manually observed. Once it deviates from the basic value, it means that the swing arm 801 is skewed, that is, the ends of the main and auxiliary rotor screws are not flush. In this case, the installation accuracy is not up to standard and needs to be adjusted and repaired.
