Description

Technical Field

[0001] The present invention relates to the field of compressor test benches, and particularly to a compressor test bench. Background Art

[0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, and is the heart of a refrigeration system. Compressors are classified into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc. A piston compressor generally consists of a housing, an electric motor, a cylinder block, a piston, control equipment, and a cooling system. The cooling methods include oil cooling, air cooling, and natural cooling. A linear compressor has no shaft, no cylinder block, sealing, and heat dissipation structures, and uses the principle of magnetic levitation and the hydrodynamic structure of a spiral ring to compress gas and provide power for refrigeration.

[0003] At the current stage, in order to be fixed firmly, the volume of the compressor test bench is relatively large, resulting in inconvenience in carrying. When conducting an external test, it needs to be disassembled, transported, and reassembled, which is rather troublesome.

[0019] Compared with the prior art, the present invention provides a compressor test bench, which has the following beneficial effects:

[0020] 1. For this compressor test bench, by rotating the provided turning handle, the bidirectional lead screw can be driven to rotate, so that one side of the fixing component can be threadedly connected to the bidirectional lead screw. At this time, the two fixing components can be driven to move towards the opposite side, and when the compressor is being tested, a positioning effect can be achieved on it.

[0021] 2. For this compressor test bench, through the provided groove, the compressor can be placed during the test. When the compressor has an irregular shape or a large volume, it can be directly placed on the top of the test bench body. When the fixing component moves, the matching component inside it will be driven to move together. When the matching component disengages from the positioning strip, the first strong spring can bounce up the matching component, so that the matching component can drive the fixing component to perform positioning processing on the compressor.

[0022] 3. For this compressor test bench, through the provided second strong spring, it can always bounce the matching block outwards, and two second strong springs are installed at each matching block, so that the matching block can adapt to different shapes of compressors to perform auxiliary positioning processing on them. At the same time, the bottom of the matching block is inclined. When it is necessary to store the matching block and the matching component, the matching component can be directly pressed down. After rotating the positioning strip to the top of the matching component through the provided positioning strip, the matching component can be stored. Based on this, it is convenient to carry the test bench body.

[0023] 4. The compressor test bench is convenient for carrying the test bench body out through the provided handle. By moving the provided locking component, the clamping block can be driven to move left and right. After moving it to the locking block, it can be clamped in the inner cavity of the clamping groove with the cooperation of the spring, so that the handle can be positioned based on this. Through the provided nylon rope, when positioning the compressor, the compressor can be tied up, and at the same time, it is convenient to carry and transport the positioned compressor.

[0024] 5. The compressor test bench is convenient for storing the legs through the provided positioning disk. When carrying the test bench body, its floor area can be reduced, and the telescopic column can adjust its length. When placing the test bench body, it can be adjusted according to the usage requirements. Therefore, it is convenient to test the compressor anytime and anywhere. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the technical means, creative features, achieving purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0033] Embodiment 1:

[0034] As Figure 1 , Figure 2 shown, a compressor test bench includes a test bench body 1. There is a groove 2 opened on the top of the test bench body 1. On both sides of the inner cavity of the groove 2, fixing components 7 are symmetrically and movably connected. In the inner cavities of the two fixing components 7, an adapting component 8 is symmetrically and movably connected. In the middle of both sides of the inner cavity of the groove 2, moving grooves 4 are symmetrically opened. In the inner cavity of one moving groove 4, a bidirectional lead screw 5 is rotatably connected. One end of the bidirectional lead screw 5 extends to the outside of the test bench body 1. At one end of the bidirectional lead screw 5 extending to the outside of the test bench body 1, a turning handle 3 is installed. The middle parts on both sides of the adapting component 8 are symmetrically and movably connected in the inner cavities of the two moving grooves 4. One side of the adapting component 8 is threadedly connected to the outer wall of the bidirectional lead screw 5. The fixing component 7 is a cavity structure with the top communicating with the outside. On both sides of the bottom of the inner cavity of the fixing component 7, fixing columns 10 are symmetrically installed. At the top of the fixing column 10, a limiting block 9 is installed. A first strong spring 11 is wound around the outer wall of the fixing column 10. The bottom of the first strong spring 11 is installed at the bottom of the inner cavity of the fixing component 7. The top of the first strong spring 11 is installed at the bottom of the adapting component 8. The adapting component 8 is sleeved on the outer wall of the fixing column 10. The limiting block 9 is movably connected in the inner cavity of the adapting component 8. At both ends of the opposite sides of the two adapting components 8, adapting blocks 12 are symmetrically and movably connected. The bottom of the side of the adapting block 12 close to the adapting component 8 is inclined. At both ends of the side of the adapting block 12 close to the adapting component 8, second strong springs 14 are symmetrically installed. The other ends of the second strong springs 14 are installed in the inner cavity of the adapting component 8. A first fixing rod 13 is installed in the inner cavity of the adapting component 8. The second strong spring 14 is wound around the outer wall of the first fixing rod 13. At the other end of the first fixing rod 13, a limiting disk 15 is installed. The adapting block 12 is sleeved on the outer wall of the first fixing rod 13. The limiting disk 15 is movably connected in the inner cavity of the adapting block 12;

[0035] By rotating the set handle 3, the bidirectional lead screw 5 can be driven to rotate, so that one side of the fixed component 7 can be threadedly connected to the bidirectional lead screw 5. At this time, the two fixed components 7 can be driven to move towards the opposite side, which can play a positioning effect when testing the compressor. Through the set groove 2, the compressor can be placed during the test. When the compressor has an irregular shape or a large volume, it can be directly placed on the top of the test bench body 1. When the fixed component 7 moves, the matching component 8 inside its cavity will move together. When the matching component 8 disengages from the positioning bar 6, the first strong spring 11 can bounce the matching component 8 up, so that the matching component 8 can drive the fixed component 7 to position the compressor. Through the set second strong spring 14, it can always bounce the matching block 12 outward, and two second strong springs 14 are installed at each matching block 12, so that the matching block 12 can adapt to different-shaped compressors for auxiliary positioning. At the same time, the bottom of the matching block 12 is inclined. When it is necessary to store the matching block 12 and the matching component 8, the matching component 8 can be directly pressed down. By rotating the set positioning bar 6 to the top of the matching component 8, the matching component 8 can be stored. Based on this, it is convenient to carry the test bench body 1.

Two ends of the test bench body 1 are symmetrically and movably connected with locking components 18. Two sides of the test bench body 1 are symmetrically provided with moving grooves 17. Opposite sides of the two locking components 18 are symmetrically and movably connected with clamping blocks 21. The clamping blocks 21 are movably connected in the moving grooves 17 and the inner cavity of the test bench body 1. The top and bottom of the clamping blocks 21 are symmetrically installed with movable blocks 22. The top and bottom of the inner cavity of the locking component 18 are symmetrically installed with second fixing rods 23. Springs 24 are wound around the outer walls of the second fixing rods 23. One end of the spring 24 is installed in the inner cavity of the locking component 18, and the other end of the spring 24 is installed on the outer wall of the movable block 22. The movable blocks 22 are sleeved on the outer walls of the second fixing rods 23, and the movable blocks 22 are movably connected in the inner cavity of the locking component 18. The outer wall of the locking block 19 is provided with a card slot 20. The sizes of the card slot 20 and the clamping block 21 are adapted to each other. The clamping block 21 is inserted into the inner cavity of the locking block 19 through the card slot 20. One side of the clamping block 21 is inclined. The other end of the nylon rope 25 is installed in the inner cavity of the test bench body 1. The nylon rope 25 is stored in the inner cavity of the test bench body 1;

[0038] Through the provided handle 16, it is convenient to carry the test bench body 1 outdoors. By moving the provided locking component 18, the clamping block 21 can be driven to move left and right. After moving it to the locking block 19 and cooperating with the spring 24, it can be clamped in the inner cavity of the clamping groove 20. Based on this, the handle 16 can be positioned. Through the provided nylon rope 25, when positioning the compressor, the compressor can be tied up, and at the same time, it is convenient to transport and carry the positioned compressor.

[0039] Embodiment Three:

[0040] As Figure 1 , Figure 5 , Figure 6 shown, for a compressor test bench, legs 28 are symmetrically arranged around the bottom of the test bench body 1. A positioning disk 27 is installed in the center of the bottom of the test bench body 1. A telescopic column 31 is installed in the inner cavity of the leg 28. Fixed seats 26 are symmetrically installed around the bottom of the test bench body 1. One end of the leg 28 is installed at the fixed seat 26 through a positioning anchor bolt.

The positioning screw 30 is attached to the outer wall of the leg 28;

[0041] Through the provided positioning disk 27, it is convenient to store the legs 28. When carrying the test bench body 1, its floor area can be reduced, and the telescopic column 31 can adjust its length. When placing the test bench body 1, it can be adjusted according to the usage requirements. Therefore, it is convenient to test the compressor anytime and anywhere.

[0042] It should be noted that the present invention is a compressor test bench. When in use, one end of the leg 28 is taken out from the positioning disk 27, rotated to a suitable angle and then positioned through a positioning anchor bolt. The positioning screw 30 is loosened, and the height of the telescopic column 31 is adjusted. After the height adjustment is completed, the telescopic column 31 is positioned through the connection between the positioning screw 30 and the positioning block 32. At this time, the test bench body 1 can be placed on the ground;

[0043] Place the compressor at the groove 2 or the test bench body 1. Rotate the positioning bar 6 to move it away from the top of the adapter assembly 8. At this time, the first strong spring 11 will lift the adapter assembly 8 upwards. Rotate the turning handle 3 to drive the bidirectional lead screw 5 to rotate in the inner cavity of the movable slot 4, so that one side of the adapter assembly 8 can be threadedly connected thereto. At this time, the two adapter assemblies 8 can drive the two fixing assemblies 7 to move, and the fixing assemblies 7 and the adapter assemblies 8 can be attached to the outer wall of the compressor. Based on this, the positioning process of the compressor can be completed. At this time, the compressor can be tested. At the same time, the compressor can also be tied with a nylon rope 25 to improve the positioning and fastening degree of the compressor. Specifically, the locking assembly 18 can be moved to drive the block 21 to disengage from the inner cavity of the card slot 20. At this time, the nylon rope 25 can be withdrawn from the inner cavity of the test bench body 1 through the handle 16;

[0044] When the test bench body 1 needs to be carried, retract the telescopic column 31 into the inner cavity of the leg 28, rotate the leg 28, and snap one end of it into the inner cavity of the positioning disk 27.
