[0002] During the factory assembly process of the compressor, in order to ensure the dynamic stability of the compressor rotor and determine whether the performance of the compressor transmission system after assembly meets the factory requirements, each compressor needs to be subjected to an operation test. Through two oil injections, the operation of the compressor during use is simulated, and the exhaust pressure and holding pressure of the compressor are tested. Under the set speed, operating time and holding time, the exhaust pressure must reach the calibrated value. If it does not meet the standard, an abnormal pressure alarm will be issued. The holding pressure reaches the set value. If it does not meet the standard, a non-pressure holding alarm will be issued. Based on the alarm situation, it is judged whether the compressor performance is qualified.

The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figures 1 to 15 The compressor operation test bench shown includes: a frame and a test bench 10 assembled on the frame for receiving the compressor 01, a docking mechanism 20 for controlling the vertical and / or horizontal movement of the test bench 10, and an operating mechanism 30 for simulating the operation of the compressor 01; The test bench 10 is arranged horizontally, the docking mechanism 20 is fixedly connected to the bottom of the test bench 10, and the operating mechanism 30 is arranged opposite to the main shaft assembly end of the compressor 01; The operating mechanism 30 includes an operating bracket 31, an operating drive member 32, a rotating assembly 33, and a telescopic assembly 34. The operating bracket 31 is fixedly connected to the working side of the frame, and its interior is vertically divided into a drive assembly space and a transmission assembly space. The operation driving member 32 is arranged in the driving assembly space, the rotating assembly 33 is arranged in the transmission assembly space and connected to the operation driving member 32, and one end of the telescopic assembly 34 is movably connected to the telescopic assembly 34; When the telescopic assembly 34 slides out along the axis of the rotating assembly 33, the other end of the telescopic assembly 34 forms a docking effect with the main shaft assembly end of the compressor 01. When the operating drive 32 works, it drives the rotating assembly 33, the telescopic assembly 34 and the main shaft assembly end of the compressor 01 to rotate synchronously.

[0024] The present invention uses an automated operating test bench, in which the test bench 10 receives the compressor 01. The docking mechanism 20 can automatically drive the test bench 10 at a constant speed and force, so that the test bench 10 can be accurately moved to a set position; the operating mechanism 30 can automatically achieve accurate and stable docking with the compressor 01 on the test bench 10, and stably drive the rotor of the compressor 01 to rotate according to a preset program to perform a standardized operating test without manual assistance, greatly shortening the preparation time before testing a single compressor 01 and increasing the test throughput; effectively reducing human errors, making the test conditions of each compressor 01 consistent, and improving the reliability of the results.

[0025] Specifically, the test bench 10 is horizontally arranged to provide a stable bearing platform for the compressor 01, ensuring that the compressor 01 is placed stably to facilitate subsequent operation test operations; the docking mechanism 20 is connected to the bottom of the test bench 10, controlling its movement to the preset position in the vertical and horizontal directions, with precise position control to improve docking accuracy and efficiency; the operating bracket 31 is fixed to the frame to provide support and installation space for internal components, and is divided into a drive assembly space and a transmission assembly space to facilitate component layout and installation; the telescopic component 34 slides out along the axis of the rotating component 33 and automatically and accurately docks with the main shaft assembly end of the compressor 01. The operating drive member 32 generates power in the drive assembly space, which is transmitted through the rotating component 33 and the docking action of the telescopic component 34, thereby realizing power transmission of the operating drive member 32, causing the telescopic component 34 and the main shaft assembly end of the compressor 01 to rotate synchronously, simulating the working state of the compressor 01.

[0026] When using the above compressor 01 operation test bench to conduct an operation test, the compressor 01 needs to be placed on the test bench first, and the test bench 10 supports the compressor 01 to ensure that it is placed stably and the main shaft assembly end of the compressor 01 faces the working side; the docking mechanism 20 controls the test bench 10 and the compressor 01 to move synchronously along the vertical and / or horizontal directions until the main shaft assembly end of the compressor 01 is arranged relative to the telescopic component 34. At this time, the test bench 10 and the main shaft assembly end of the compressor 01 move to the set position; the telescopic component 34 slides out along the axial direction of the rotating component 33 and forms a shape with the main shaft assembly end of the compressor 01 The operating drive member 32 works, so that the rotating assembly 33 drives the telescopic assembly 34 to rotate synchronously around the axis direction, and controls the synchronous rotation of the main shaft assembly end connected to the telescopic assembly 34 to simulate the operation of the compressor 01; confirm that the various working data of the compressor 01, including the exhaust pressure, the holding pressure and the performance indicators, are within the normal range during the simulation and the corresponding alarm is issued, and then the operating drive member 32 stops working; the telescopic assembly 34 releases the docking effect on the main shaft assembly end and slides back to reset, and the docking mechanism 20 controls the test bench 10 and the compressor 01 to reset to the initial position, and the rack transports the compressor 01 to the next station.

[0027] Based on the above embodiment, the rotating assembly 33 includes a base 331, an adjustment plate 332, a flange sleeve 333, an intermediate flange sleeve 334, a sliding sleeve 335 and a telescopic fixing sleeve 336; The base 331 has an assembly hole in the middle. The adjustment plate 332 is located on the side of the base 331 facing the interior of the transmission assembly space. One end of the flange sleeve 333 is assembled to the adjustment plate 332. The intermediate flange sleeve 334 is assembled to the other end of the flange sleeve 333. The sliding sleeve 335 is engaged with the inner side of the intermediate flange sleeve 334. The telescopic fixing sleeve 336 is located in the flange sleeve 333 and assembled to the outside of the end of the intermediate flange sleeve 334 that extends into the flange sleeve 333. The top of the base 331 has a screw plate 337 arranged opposite to the adjustment plate 332 . A groove is formed opposite the adjustment plate 332 and the screw plate 337 . An adjustment screw 338 is built into the groove and fixedly connected to the screw plate 337 .

[0028] Specifically, the base 331 serves as the basic support structure of the rotating assembly 33, and the assembly hole in the middle is used for assembly and connection with other components to ensure the stable installation and positioning of the entire rotating assembly 33 in the operating mechanism 30; the adjustment plate 332 is located on the side of the base 331 facing the inside of the transmission assembly space, and is used to assemble components such as the flange sleeve 333, and its position can be adjusted by cooperating with the adjusting screw 338 and the screw plate 337, so as to achieve fine-tuning of the position of the entire rotating assembly 33; the flange sleeve 333 plays a connecting and transition role, ensuring a stable and reliable connection between the adjustment plate 332 and the middle flange sleeve 334, and at the same time providing a stable connection for the middle flange sleeve 334. The intermediate flange sleeve 334 provides installation and positioning space to ensure the concentricity and stability of power transmission; the intermediate flange sleeve 334 and the sliding sleeve 335 on its inner side are used to further support and guide the axial movement of the telescopic component 34, ensuring that the telescopic component 34 maintains stable linear motion during the telescopic process, reducing offset and shaking during the movement, and improving the accuracy and reliability of power transmission; the telescopic fixing sleeve 336 is used to fix and limit the intermediate flange sleeve 334 to prevent the intermediate flange sleeve 334 from axial displacement during the movement, while enhancing the structural rigidity of the entire rotating component 33 and improving its load-bearing capacity and fatigue resistance.

[0029] When the operating drive member 32 is started, the power generated is transmitted to the flange sleeve 333 and the middle flange shaft sleeve 334 of the rotating component 33, and then the power is stably transmitted to the telescopic component 34 through the cooperation of the sliding sleeve 335 and the telescopic fixing sleeve 336, and finally drives the telescopic component 34 and the main shaft assembly end of the compressor 01 to rotate synchronously.

[0030] Based on the above embodiment, the rotating assembly 33 further includes a first transmission wheel 339, a bushing 3310, a second transmission wheel 3311 and a transmission belt 3312; The first transmission wheel 339 is assembled on the outer axial surface of the telescopic fixing sleeve 336 extending out of the base 331 away from the transmission assembly space.

As a flexible transmission component connecting the first transmission wheel 339 and the second transmission wheel 3311, it has good elasticity and wear resistance, can achieve smooth power transmission, buffer the impact and vibration during operation, and reduce noise.

[0032] After the operating drive member 32 is started, the second transmission wheel 3311 on its output end rotates accordingly, and the second transmission wheel 3311 transmits power to the first transmission wheel 339 through the transmission belt 3312. The transmission belt 3312 forms a closed-loop transmission under the action of the friction force between the two transmission wheels, ensuring that power is stably and continuously transmitted from the second transmission wheel 3311 to the first transmission wheel 339; driven by the first transmission wheel 339, the telescopic fixing sleeve 336 starts to rotate, and the telescopic fixing sleeve 336 is tightly connected with the telescopic component 34, thereby driving the telescopic component 34 to rotate synchronously, and the other end of the telescopic component 34 is docked with the assembly end of the main shaft of the compressor 01, thereby driving the main shaft of the compressor 01, simulating the actual operation of the compressor 01.

The two ends of the adapter sleeve 342 are respectively connected to the telescopic rod 341 and the rotating sleeve 343. The rotating sleeve 343 is set at an opening at one end away from the adapter sleeve 342, and a step surface is formed on the inner side; one end of the torque sleeve 344 is assembled at the opening of the rotating sleeve 343 and slides relatively along the axial direction of the rotating sleeve 343. One end of the copper sleeve 345 cooperates with the step surface and is located between the torque sleeve 344 and the rotating sleeve 343; the spline sleeve 346 is assembled on the other end face of the torque sleeve 344, and the end face facing the assembly end of the compressor 01 main shaft is concave, forming a spline hole adapted to the assembly end of the main shaft; The telescopic driving member 347 is fixed on the adjusting plate 332, one end of the clamping plate 348 is fixed to the executing end of the telescopic driving member 347, and the other end forms two vertical legs.

[0035] When the telescopic drive 347 starts to provide power for the telescopic assembly 34, the splint 348 fixed on the execution end of the telescopic drive 347 and the first clamping claw 349 connected to the splint 348 drive the telescopic sleeve 3411 connected thereto to synchronously move axially, so that the telescopic sleeve 3411 drives the internal telescopic rod 341, adapter sleeve 342, rotating sleeve 343, torque sleeve 344, copper sleeve 345, and spline sleeve 346 to move synchronously to achieve telescopic movement.

[0038] Based on the above embodiment, the telescopic assembly 34 further includes an extension plate 3418 , a detection switch 3419 and a sensing head 3420 ; A second strip-shaped groove 344a is provided on the outer axial surface of the torque sleeve 344 along the axial direction.

The detection switch 3419 is installed on the side of the extension plate 3418 facing the second strip groove 344a, and is used to monitor the position changes of the induction head 3420 in real time, and feed back the monitored position information to the control system, thereby realizing real-time monitoring and automatic control of the position of the telescopic component 34. , wherein the detection switch 3419 usually adopts a non-contact sensor, such as a photoelectric switch or a magnetic induction switch, which can quickly and accurately detect the approach or distance state of the sensing head 3420; the sensing head 3420 slides in the second strip groove 344a with the movement of the rotating sleeve 343 and the copper sleeve 345, and is arranged opposite to the detection switch 3419. Its position change can be captured in real time by the detection switch 3419, ensuring that the detection switch 3419 can indirectly monitor the axial position change of the torque sleeve 344, thereby realizing accurate detection of the telescopic state of the telescopic component 34.
