Description

Technical Field

[0001] The present application relates to the field of compressor test benches, and in particular to a semi-automatic assembly test bench for a small compressor main engine. Background Art

[0002] After the design of a small screw compressor is completed, the prototype needs to be tested for performance. A common test bench usually includes a drive motor as the compressor drive source, an intake valve and an exhaust pipe. The drive motor drives the rotor in the compressor to rotate, and the intake valve is connected to the air filter, so that the air entering the compressor is cleaner and the data obtained is more accurate.

[0003] On conventional test benches, the intake valve is usually fixed to the intake end of the compressor by bolts, which makes installation and removal more troublesome. In addition, the position, design and number of bolt holes at the intake end of different compressors are different. When testing compressors of different models, the corresponding intake valve needs to be replaced, further increasing the testing cost and complexity. Summary of the invention

[0004] In order to solve the problem that the assembly process of a traditional compressor test bench is relatively complicated during testing, the present application provides a small-scale semi-automatic assembly test bench for a compressor main engine.

[0005] The semi-automatic assembly test bench for a small compression main engine provided by the present application adopts the following technical solution:

[0006] A small compression host semi-automatic assembly test bench, comprising:

[0007] Mounting table, used to install testing equipment and place small compression host;

[0008] A supporting mechanism, arranged on the mounting platform, for placing a small compression host;

[0009] A sealing plate, on which an air inlet hole is opened, one side of which is used to install an air inlet valve, the air inlet valve is connected to the air inlet hole, and the other side of which is used to fit tightly against the air inlet end of the small compressor main unit to form a sealed connection between the air inlet valve and the small compressor main unit;

[0011] The driving device is used to drive the rotor of the small compression main unit to rotate.

[0012] Through the above technical scheme, the air intake valve and the small compression host are sealed and connected through the sealing pressure plate. For different models of small compression hosts, the connection between the air intake valve and the small compression host can be completed by pressing the sealing pressure plate cover on the mounting surface of the air intake end of the small compression host. The connection method is relatively simple and has a wide applicability.

[0013] Optionally, the pressing device comprises:

[0014] A hydraulic cylinder, provided on the supporting mechanism;

[0015] The pressing block is connected to the piston rod of the hydraulic cylinder and is used to cooperate with the hydraulic cylinder to press and fix the sealing pressing plate on the small compression main machine.

[0016] Optionally, a positioning tube is provided on the sealing pressure plate, the positioning tube is connected to the air inlet hole, and the positioning tube is used to be inserted into the air inlet of the small compression main unit for positioning.

[0017] Optionally, the supporting mechanism includes:

[0018] A support seat, arranged on the mounting platform, and the hydraulic cylinder is arranged on the support seat;

[0019] A slide rail, arranged on the support seat;

[0020] A plurality of support blocks are provided and are all slidably mounted on the slide rails, and are used to cooperate with the bottom feet of the small compression host to support the small compression host;

[0021] A fixing member is used to fix the support block on the slide rail.

[0022] Optionally, the driving device includes:

[0023] A driving motor is arranged on the mounting platform;

[0024] A transmission shaft, one end of which is drivingly connected to the main shaft of the driving motor;

[0025] The main engine shaft sleeve has one end connected to the transmission shaft and the other end used to connect to the input shaft of the small compression main engine.

[0026] Optionally, a centering groove is provided in the middle of the side of the sealing pressure plate, and the pressure block is rotationally connected to the piston rod of the hydraulic cylinder.

[0027] Optionally, both side edges of one end of the pressing block used to press the sealing pressing plate are chamfered.

[0028] Through the above technical solution, the chamfer is used to match the centering groove. When the centering groove and the pressing block are not directly opposite, the length of the pressing block that can be pressed in the centering groove is extended.

[0029] Optionally, the main engine sleeve includes:

[0030] A base plate is arc-shaped and connected to one end of the transmission shaft, and a keyway is provided on its inner wall;

[0031] The clamping plate is arc-shaped and rotatably mounted on the base plate, and is assembled with the base plate;

[0032] The locking bolt is slidably mounted on the base plate, one end of which passes through the base plate and is threadedly connected to the clamping plate, and is used to lock the base plate and the clamping plate so that the base plate and the clamping plate are connected to the input shaft of the small host.

[0037] Optionally, the support block is provided with a first pressure sensor for detecting the gravity of the small compression mainframe, and the first pressure sensor is electrically connected to the driving assembly.

[0038] In summary, the air intake valve of the present application is sealed and connected to the small compression host through a sealing pressure plate. For small compression hosts of different models, the connection between the air intake valve and the small compression host can be completed by pressing the sealing pressure plate cover on the mounting surface of the air intake end of the small compression host. The connection method is relatively simple and has wide applicability.

[0039] And in the process of tightening the locking bolts, the input shaft of the small compression host will be highly coaxial with the transmission shaft. At this time, if the actual height of the small compression host is lower than the required height, the small compression host will be lifted up, and the first pressure sensor will detect that the pressure of the small compression host on the top wall of the support block is reduced. At this time, the lifting motor will start to continue to lift the lifting plate until the pressure value increases to the registered pressure. Otherwise, the small compression host will be pressed down, and the first pressure sensor will detect that the pressure of the small compression host on the top wall of the support block is increased. At this time, the lifting motor will start to lower the lifting plate until the pressure value decreases to the registered pressure, so that the coaxiality between the small compression host and the transmission shaft is higher, and the vibration generated during the testing of the small compression host is smaller.

[0055] Reference Figure 3 and Figure 6 A circular air inlet hole 31 is formed through the sealing plate 3 , and an air inlet valve 32 is fixedly installed on one side of the sealing plate 3 by bolts. The air inlet valve 32 is sealed and fixedly connected to the air filter 11 through the air inlet hose 12 .

[0056] Reference Figure 3 and Figure 7A positioning tube 34 is integrally provided on the other side of the sealing plate 3. The positioning tube 34 is coaxial with the air inlet hole 31. The positioning tube 34 is used to be inserted into the air inlet end of the small compression host 10 to supply air, and then a seal is formed by pressing and fixing the sealing plate 3 on the mounting surface 101 of the air inlet end of the small compression host 10.

[0057] Reference Figure 1 and Figure 2 A cantilever crane 13 is fixedly installed on the ground on one side of the mounting platform 1, and a clamping device 4 is provided on the mounting platform 1. An oil-gas separator 14 is fixedly installed in the mounting platform 1. The cantilever crane 13 is used to hoist a small compression host 10, and the clamping device 4 is used to clamp and fix the sealing plate 3.

[0058] Reference Figure 1 and Figure 2 An exhaust hose 15 is fixedly installed on the air inlet side of the oil-gas separator 14 through a sealing joint. One end of the exhaust hose 15 is sealed and connected to a sensor connecting seat 16 , and one end of the sensor connecting seat 16 is sealed and connected to an exhaust pipe quick-connect male connector 151 .

[0059] Reference Figure 3 and Fig.10 Before the test, an exhaust pipe quick-plug female connector 103 which is plugged into and matched with the exhaust pipe quick-plug male connector 151 is sealed and installed at the air outlet end of the small compressor main unit 10 .

[0060] At the beginning of the test, first, the small compression host 10 is lifted to the support mechanism 5 by the cantilever crane 13 and lowered, then the input shaft of the small compression host 10 is connected to the drive device 6, the exhaust pipe quick-plug male connector 151 is connected to the exhaust pipe quick-plug female connector 103, the sensor is installed on the sensor connecting seat 16, and then the positioning tube 34 is inserted into the air inlet of the small compression host 10, and then the sealing pressure plate 3 is clamped and fixed by the clamping device 4, and finally the drive device 6 is started to test the small compression host 10.

[0061] Reference Figure 1 A frequency conversion cabinet 17 is fixedly installed on the ground at one side of the mounting platform 1 for power supply, and an operation panel 18 is fixedly installed on the ground at one side of the mounting platform 1 for overall control and display of data.

[0062] Reference Figure 1 and Figure 2 After the driving device 6 is started, the air is filtered by the air filter 11 and enters the small compression host 10 along the air intake hose 12. The compressed air enters the oil-gas separator 14 along the exhaust hose 15. The pressure value of the compressed air is detected by the sensor and transmitted to the operation panel 18 for display.

[0063] Reference Figure 1 and Figure 2An ASME nozzle flow device 19 is provided on the ground on one side of the mounting platform 1. The ASME nozzle flow device 19 is sealedly connected to the air inlet end of the oil-gas separator 14 through a pipeline. The flow rate of the exhaust gas of the small compression host 10 is detected by the ASME nozzle flow device 19, and the flow rate detection value is transmitted to the operation panel 18 for display.

[0064] Reference Figure 1 The ground on both sides of the mounting platform 1 is paved with guide rails 2, and two protection boxes 21 are slidably installed on the guide rails 2. The protection boxes 21 cover the mounting platform 1 to protect the tester when testing the small compression host 10.

[0065] Reference Figure 3 The supporting mechanism 5 includes a supporting seat 51, two slide rails 52 and a plurality of supporting blocks 53, two of which are designed in this embodiment. The driving device 6 includes a driving motor 61 fixed on the mounting table 1, a transmission shaft 62 coaxially fixed to the output shaft of the driving motor 61 through a flange, and a mainframe sleeve 7 for connecting the transmission shaft 62 and the input shaft of the small compression mainframe 10.

[0066] The pressing device 4 includes a plurality of hydraulic cylinders 41 and a pressing block 42 rotatably mounted on the piston rod of the hydraulic cylinder 41. In this embodiment, there are two hydraulic cylinders 41. The hydraulic cylinder 41 is vertically mounted, and the pressing block 42 is horizontally arranged.

[0067] Reference Figure 3 The support base 51 in this embodiment includes a bottom plate 511 and a lifting plate 512. In a test scenario where only one type of small compression host needs to be tested, the support base 51 only includes a bottom plate 511 for support.

[0068] Reference Figure 3 The bottom plate 511 is located on one side of the output shaft of the driving motor 61 . The bottom plate 511 is horizontal and a shock absorbing block 514 is fixedly installed at the four top corners of the bottom wall by bolts. The shock absorbing block 514 is threadedly fixedly installed on the table surface of the mounting platform 1 .

[0069] Reference Figure 3 The lifting plate 512 is horizontal, and the lifting plate 512 is vertically slidably installed on the top wall of the bottom plate 511 through the light rod 513. The two slide rails 52 are fixedly installed on the top wall of the lifting plate 512. The two slide rails 52 are parallel to each other. The two support blocks 53 are both slidably installed on the slide rails 52, and the support blocks 53 slide in the direction close to or away from the output shaft of the drive motor 61.

[0070] Reference Figure 3The support block 53 is provided with a fixing part 54, and the fixing part 54 includes a fixing bolt 541. One end of the fixing bolt 541 is threaded through the support block 53 and pressed against the side wall of the slide rail 52 to fix the support block 53 and the slide rail 52. During the test, two pairs of supporting feet 102 of the small compression host 10 are respectively placed on the top walls of the two support blocks 53. The distance between the two support blocks 53 is adjusted by sliding to adapt the spacing between the supporting feet 102 of small compression hosts 10 of different models.

[0071] Reference Figure 3 , Figure 4 and Figure 5 The two hydraulic cylinders 41 are respectively arranged on both sides of the top wall of the bottom plate 511 , the base of the hydraulic cylinder 41 is fixedly connected to the top wall of the bottom plate 511 , and the base of the hydraulic cylinder 41 slides through the lifting plate 512 .

[0072] Reference Figure 3 and Figure 7 A centering groove 35 is provided on one side of the sealing plate 3 which is away from the positioning tube 34 and in the middle of both ends of the side. A sealing ring 33 is embedded in one side of the sealing plate 3 where the positioning tube 34 is provided. The sealing ring 33 surrounds the positioning tube 34 to increase the sealing performance when the sealing plate 3 is pressed against the mounting surface 101 of the air inlet 1 of the small compression main unit 10.

[0073] Reference Figure 3 When the sealing pressure plate 3 is placed on the mounting surface 101 at the air inlet of the small compression main unit 10, the two ends of the sealing pressure plate 3 are respectively located at the two hydraulic cylinders 41, and the pressure block 42 is rotated until one end of the pressure block 42 is aligned with the centering groove 35 of the sealing pressure plate 3, and then the hydraulic cylinder 41 is started to retract the piston rod, and one end of the pressure block 42 is pressed against the bottom wall of the centering groove 35 to press and fix the sealing pressure plate 3 on the small compression main unit 10, and at the same time, the small compression main unit 10 is pressed and fixed on the support block 53.

[0074] Since one end of the pressure block 42 is located in the centering groove 35, the overall pressure of the two pressure blocks 42 on the sealing pressure plate 3 is relatively uniform. After the sealing pressure plate 3 is tightened, the pressure on the sealing ring 33 is relatively uniform. The sealing performance between the sealing pressure plate 3 and the mounting surface 101 at the air inlet of the small compression main unit 10 is better and leakage is not easy to occur.

[0075] Reference Figure 3 and Figure 5, chamfers 43 are provided on both sides of the end face of the sealing platen 3 pressed by the pressing block 42. After the sealing platen 3 is placed on the mounting surface 101 of the air inlet of the small compression host 10 of different models, the centering groove 35 of the sealing platen 3 and the pressing block 42 are not completely aligned, and the pressing block 42 needs to be rotated and adjusted so that the end of the pressing block 42 can be pressed against the bottom of the centering groove 35. The chamfer 43 is designed to increase the length of the pressing block 42 in the centering groove 35 when it is tilted and pressed in the centering groove 35, and the friction between the pressing block 42 and the sealing platen 3 is increased, so that the pressing block 42 is not easily separated from the sealing platen 3 due to the vibration generated when the small compression host 10 is started and tested, and the pressure provided by the pressing block 42 is more stable.

[0076] Reference Figure 3 A driving assembly 9 is provided on the surface of the mounting table 1. The driving assembly 9 includes a lifting motor 91 fixedly mounted on the surface of the mounting table 1 and a screw 92. The screw 92 is rotatably mounted on the surface of the mounting table 1. The screw 92 is vertical and the upper end passes through the bottom plate 511 and the lifting plate 512 in sequence. The screw 92 is threadedly matched with the lifting plate 512, and the screw 92 is connected to the lifting motor 91 through a gear set.

[0077] Reference Figure 3 and Figure 6 and Figure 7 The sealing platen 3 is provided with a measuring piece 36, which includes two second pressure sensors 361. Mounting holes 37 are provided at both ends of the sealing platen 3. The mounting holes 37 are used for threadedly mounting the second pressure sensors 361. The mounting holes 37 are connected to the centering groove 35. The second pressure sensor 361 is used to detect the pressure when the pressure block 42 is pressed against the bottom of the centering groove 35, and the second pressure sensor 361 is electrically connected to the lifting motor 91 through the operation panel 18.

[0078] Reference Figure 3 and Figure 6 and Figure 7 Since the height of the output shaft of the driving motor 61 is fixed, the height of the lifting plate 512 is adjusted to adapt to different models of small compression hosts 10, so that the input shaft and the transmission shaft 62 of different models of small compression hosts 10 are coaxial.

[0079] Reference Figure 3 and Figure 6 and Figure 7 When adjusting, the piston rod of the hydraulic cylinder 41 is fully extended, and the lifting plate 512 is adjusted to the highest position. Then, the sealing pressure plate 3 is installed to the small compression main unit 10. After rotating the pressure block 42 to align with the centering groove 35, the hydraulic cylinder 41 is started to retract the piston rod.

[0080] Reference Figure 3 and Figure 6 and Figure 7When the pressure block 42 is pressed against the bottom of the centering groove 35, the second pressure sensor 361 detects the pressure and starts the lifting motor 91, and the lifting motor 91 drives the lifting plate 512 to descend. When the second pressure sensor 361 detects that the pressure returns to zero, the lifting motor 91 stops. The above process is repeated until the piston rod of the hydraulic cylinder 41 is fully retracted. The second pressure sensor 361 detects that the pressure returns to zero for the last time, and the lifting motor 91 stops. Compare the distance between the mounting surface 101 at the air inlet of the top wall of the small compression host 10 and the axis of the input shaft of the small compression host 10, and the distance between the bottom wall of the pressure block 42 and the axis of the output shaft of the drive motor 61 after the piston rod of the hydraulic cylinder 41 is fully retracted. It can be obtained how much height the lifting plate 512 needs to be adjusted at this time to make the input shaft of the small compression host 10 and the transmission shaft 62 coaxial.

[0081] Reference Figure 4 After the measurement is completed, the second pressure sensor 361 is removed to prevent interference with subsequent tests.

[0082] Reference Figure 8 and Fig. 9 The main engine shaft sleeve 7 includes an arc-shaped base plate 71, an arc-shaped clamping plate 72 and a locking bolt 73. One end of the base plate 71 is fixedly connected to one end of the transmission shaft 62 through a flange, and a keyway 711 is provided on the inner wall of the base plate 71. The clamping plate 72 is rotatably connected to the base plate 71 and is assembled with each other. The locking bolt 73 is slidably installed on the base plate 71, and one end of the locking bolt 73 passes through the base plate 71 and is threadedly connected to the clamping plate 72.

[0083] When connecting the drive motor 61 and the small compression host 10, first insert the input shaft of the small compression host 10 into the base plate 71, then rotate the clamping plate 72 to assemble with the base plate 71, tighten the locking bolt 73 to fix the base plate 71 and the clamping plate 72, and complete the transmission connection between the input shaft of the small compression host 10 and the output shaft of the drive motor 61.

[0084] Reference Figure 2 and Figure 3 A first pressure sensor is provided in each of the two support blocks 53 to detect the pressure of the small compression host 10 on the top wall of the support block 53, and the first pressure sensor is electrically connected to the lifting motor 91 through the operation panel 18. Before the input shaft of the small compression host 10 is inserted into the base plate 71, the small compression host 10 is first stably placed on the support block 53, and the pressure value generated at this time is registered as the reference value.

[0085] Reference Figure 3 , Figure 8 and Fig. 9In the process of tightening the locking bolt 73, the input shaft of the small compression host 10 will be highly coaxial with the transmission shaft 62. At this time, if the actual height of the small compression host 10 is lower than the required height, the end of the small compression host 10 close to the transmission shaft 62 will be lifted, so that the first pressure sensor close to the transmission shaft 62 detects that the pressure of the small compression host 10 on the top wall of the support block 53 is reduced. At this time, the lifting motor 91 starts to continue to lift the lifting plate 512 until the pressure value increases to the registered pressure;

[0086] On the contrary, if the actual height of the small compression host 10 is higher than the required height, as the locking bolt 73 is tightened, the end of the small compression host away from the transmission shaft 62 will be lifted, so that the first pressure sensor of the principle transmission shaft 62 detects that the pressure of the small compression host 10 on the top wall of the support block 53 is reduced. At this time, the lifting motor 91 starts to lower the lifting plate 512 until the pressure value increases to the registered pressure.

[0087] Reference Figure 3 The cross section of the slide rail 52 is designed to be dovetail-shaped, so that the cooperation between the support block 53 and the slide rail 52 is more stable, and it is not easy to cause rollover to interfere with the detection value of the first pressure sensor.

[0088] Since there may be a certain difference between the theoretical distance and the actual distance between the mounting surface 101 of the top wall air inlet of the small compression host 10 and its input shaft when the preliminary measurement is performed by the pressure block 42 and the second pressure sensor 361, resulting in a low coaxiality between the input shaft of the small compression host 10 and the transmission shaft 62, direct connection for testing will produce greater vibration and further generate greater noise. Therefore, further detection and adjustment are performed through the first pressure sensor to improve the coaxiality between the input shaft of the small compression host and the transmission shaft 62, thereby effectively reducing the vibration and noise generated during the test.

[0089] The implementation principle of the semi-automatic assembly test bench for a small compression main unit in the embodiment of the present application is as follows: before measurement, the exhaust pipe quick-plug female connector 103 is sealed and installed at the exhaust port of the small compression main unit 10. After the installation is completed, it is lifted and hoisted to the support block 53 by the cantilever crane 13.

[0090] Then, through the cooperation between the second pressure sensor 361 and the pressure block, the lifting motor automatically adjusts the lifting plate to the appropriate height, and then synchronously slides the support block 53 and the small compression host 10, inserts the input shaft of the small compression host 10 into the base plate 71, fixes the support block 53 by the fixing bolt 541, closes the clamping plate, tightens the locking bolt 73, and the operation panel 18 further fine-adjusts the height of the lifting plate 512 through the first pressure sensor. After completing the connection between the input shaft of the small compression host 10 and the transmission shaft 62, insert the positioning tube 34 into the air inlet of the small compression host 10, rotate the pressure block 42 to align with the centering groove 35, start the hydraulic cylinder 41 through the pressure block 42 and the compression sealing pressure plate 3, insert the exhaust pipe quick-plug male connector 151 into the exhaust pipe quick-plug female connector 103, and start the drive motor 61 for testing after completing the overall installation.

[0091] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
