[0002] The automobile air conditioner compressor is the core component in the air conditioning system, which is responsible for compressing the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas, thereby realizing the refrigeration cycle. However, due to long-term use, environmental factors and mechanical wear, the compressor may have various faults such as leakage, wear, electrical failure, etc. These problems not only affect the performance of the air conditioning system, but also reduce the driving experience. Therefore, regular maintenance and maintenance of the compressor become particularly important.

[0003] Currently, the automobile air conditioner compressor overhauling equipment on the market is mainly divided into two categories: manual tools and automated detection equipment. Among them, the manual tools include wrench, pressure gauge, vacuum pump, etc. These tools have low cost and are easy to operate, but they depend on the experience and skills of technicians, and are prone to misjudgment and missed detection.

[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

[0046] As one of the purposes of the present application, in order to solve the problem that the air conditioner compressor is not fixed in place during maintenance, which can easily cause the pipe to loosen and thus cause inaccurate detection results in the prior art, the following technical solutions are adopted:

[0047] As shown in Figures 1-10 An automobile air conditioner compressor maintenance device, comprising a base 1, the upper end of the base 1 is provided with a machine body 11, a switch button, a power indicator, a high-voltage indicator, a fault indicator, a control panel, a USB port and the like are arranged on the machine body 11. A platform 12 for placing the compressor is installed on one side of the machine body 11, the upper end of the platform 12 is a horizontal table top, a fixing frame 2 is fixedly installed on the upper end of the platform 12, the fixing frame 2 is a gantry, the space below the fixing frame 2 can accommodate at least one compressor, a fixing mechanism 21 is installed on the fixing frame 2, the fixing mechanism 21 is used to fix the compressor on the upper end of the platform 12, so as to avoid the vibration of the compressor during work, which can cause the position of the compressor to deviate and cause the pipe joint to loosen.

[0048] The specific introduction of the fixing mechanism 21 is as follows:

[0049] The fixing mechanism 21 comprises a nut seat 211, the nut seat 211 is fixedly installed on the fixing frame 2, the nut seat 211 is vertically arranged, and the fixing frame 2 is provided with a through hole corresponding to the nut seat 211, a screw rod 212 is threadedly connected in the nut seat 211, the lower end of the screw rod 212 passes through the through hole and is arranged, a pressing seat 213 is installed at the lower end of the screw rod 212, the pressing seat 213 is fixedly or rotatably connected to the bottom of the screw rod 212, in order to reduce friction, the connection mode of the pressing seat 213 and the screw rod 212 is preferably a rotary connection, the pressing seat 213 is made close to or away from the platform 12 by rotating the screw rod 212, so as to realize the fixing or releasing of the compressor.

[0050] As a further optimization, a rotating handle 214 is further fixedly connected to the upper end of the screw rod 212, so that the operator can realize the rotation of the screw rod 212 by controlling the rotating handle 214, which plays a role in saving labor and reducing operation difficulty.

[0051] In order to realize the continuous feeding of the compressor, reduce the time of lifting the compressor up and down, and enable the machine body 11 to work continuously, the device further comprises a carrier disc 3 installed at the upper end of the platform 12, the carrier disc 3 is horizontally arranged, and the center of the carrier disc 3 is rotationally connected with the platform 12, so that the carrier disc 3 can rotate along the vertical center line. At the same time, a part of the carrier disc 3 is located directly below the fixing mechanism 21, specifically, the part of the carrier disc 3 close to the edge, when the carrier disc 3 rotates, can transport the compressor to the fixing mechanism 21. In actual work, a plurality of compressors to be repaired can be placed equidistantly on the carrier disc 3, when the detection of the previous compressor is completed, the carrier disc is rotated to realize the rapid detection of the next compressor. Compared with the operation mode in the prior art that the previous compressor must be removed and the next compressor must be moved, time can be saved and the repair efficiency can be improved.

[0052] In order to realize the purpose of saving the time of connecting and disconnecting the pipeline of the compressor, and improve the efficiency from the aspect of pipeline disassembly and assembly, the device further comprises a switching assembly 4, the switching assembly 4 has an input end and a plurality of output ends, the input end is communicated with the gas source of the machine body 11, and the output ends are used for connecting to the gas pipes of the compressors. In use, the previous compressor and the next compressor are connected to different output ends respectively, when the detection of the previous compressor is completed, only the connecting line between the input end and the corresponding output end needs to be adjusted, so that the pipeline can be switched. Compared with the operation mode in the prior art that the pipeline of the previous compressor must be disconnected and the pipeline of the next compressor must be connected, the embodiment can utilize the repair time to realize the disconnection and connection of the pipeline, thereby saving time and improving efficiency.

[0053] In order to make the continuous feeding of the compressor and the connection of the pipeline of the compressor cooperate with each other, the switching assembly 4 is rotationally installed on the platform 12, and the carrier disc 3 and the switching assembly 4 are drivingly connected through a transmission assembly. When the carrier disc 3 rotates, the switching assembly 4 rotates synchronously, so that the carrying station on the carrier disc 3 and the pipeline connection station on the switching assembly 4 can be switched synchronously, thereby further improving the working efficiency of the compressor repair.

[0054] At the same time, in order to avoid the pipelines from crossing each other and increase the difficulty of pipeline connection, in the embodiment, the transmission assembly comprises a driving gear 431 and a driven gear 31, wherein the driving gear 431 is driven by a servo motor installed in the machine body 11. The driving gear 431 and the driven gear 31 are fixedly connected at the centers of the switching assembly 4 and the carrier disc 3 respectively, and the driving gear 431 and the driven gear 31 rotate synchronously and reversely, so that the plurality of compressors on the carrier disc 3 and the plurality of output ends on the switching assembly 4 are one-to-one corresponding. That is to say, the above-mentioned carrying station and the pipeline connection station are one-to-one matched and corresponding, and there is no crossing, so that the pipeline can be disassembled and assembled more conveniently.

[0055] In addition, since the load cell 3 and the adapter 4 are driven by gear meshing, when the clamping seat 213 presses and fixes the compressor and the load cell 3, the adapter 4 will also be fixed, thereby improving stability.

[0056] Furthermore, for practical installation considerations, the driving gear 431 and the driven gear 31 are connected by a gear set 32, and the number of gears in the gear set 32 ​​is even, so that the driving gear 431 and the driven gear 31 rotate synchronously in opposite directions. In addition, the transmission ratio of the driving gear 431 and the driven gear 31 is 1:1, so that the rotation angle of the adapter assembly 4 and the loading plate 3 can be kept consistent.

[0057] The specific details of adapter component 4 are as follows:

[0058] The adapter assembly 4 includes a rotating disk 41 and a fixed plate 51. The lower end of the rotating disk 41 is fixedly connected to a rotating shaft 43. The lower end of the rotating shaft 43 passes through the platform 12 and is fixedly connected to the drive gear 431. The fixed plate 51 is fixedly connected to the side wall of the machine body 11 and is located directly above the rotating disk 41.

[0059] To improve stability, a support shaft 44 is rotatably connected between the rotating disk 41 and the fixed plate 51, making the structure of the fixed plate 51 and the rotating disk 41 more stable.

[0060] The output end of the adapter component 4 includes a transfer tube 42. Multiple sets of transfer tubes 42 are arranged in a circular array around the center of the rotating disk 41. Each set of transfer tubes 42 includes a high-pressure tube and a low-pressure tube. The output end of the transfer tube 42 is connected to the air pipe of the compressor.

[0061] The input end of the adapter assembly 4 includes two sets of connectors 52, which are fixedly mounted on the fixed plate 51. The two connectors 52 are respectively matched with the high-pressure pipe and the low-pressure pipe. The upper end of the connector 52 is the input end, connected to the air source of the machine body 11. Specifically, the two are connected through the connecting pipe 6. The lower end of the connector 52 is movably connected to a sliding seat 53, which can slide vertically, and the upper end of the sliding seat 53 is always connected to the lower end of the connector 52. In other words, the connection or disconnection between the connector 52 and the transfer air pipe 42 is achieved by the up-and-down movement of the sliding seat 53.

[0062] When the sliding seat 53 is in the uppermost position, it is separated from the lower transfer air tube 42, allowing the lower rotating disk 41 to rotate normally. When the sliding seat 53 is in the lowermost position, it is connected to the lower transfer air tube 42.

[0063] The sliding seat 53 has an inner tube 531, the sliding seat 53 is in a whole cylindrical shape, the inner tube 531 is concentrically arranged with the sliding seat 53, the upper end of the sliding seat 53 is provided with a first annular groove 533, and the lower end of the sliding seat 53 is provided with a second annular groove 534, and the first annular groove 533 and the second annular groove 534 are concentrically arranged with the inner tube 531.

[0064] The lower end of the adapter 52 is provided with an adapter tube 521, the adapter tube 521 is inserted into the first annular groove 533, and the inner wall of the adapter tube 521 is tightly fitted with the outer wall of the inner tube 531.

[0065] The upper end of the transit gas pipe 42 is provided with an extension pipe 421, the extension pipe 421 can be plugged into the second annular groove 534, and the inner wall of the extension pipe 421 is tightly fitted with the outer wall of the inner tube 531.

[0066] The upper end of the adapter 52 has an entering end 524, the two ends of the connecting pipe 6 are respectively communicated with the gas source of the machine body 11 and the entering end 524, the gas enters into the transit gas pipe 42 along the adapter 52, the adapter tube 521, the inner tube 531 and the extension pipe 421, and then the input end of the transit gas pipe 42 is communicated with the gas pipe of the compressor through another pipe, so that the whole pipeline is communicated.

[0067] In order to avoid the sliding seat 53 from falling off the adapter 52, and to limit the up-down displacement range of the sliding seat 53, the lower end of the adapter 52 is provided with an annular sliding groove 522, the upper end of the sliding seat 53 is fixedly connected with an annular sliding block 535, and the annular sliding block 535 is slidingly arranged in the annular sliding groove 522.

[0068] It should be noted that the depth of the first annular groove 533 is greater than the depth of the annular sliding groove 522, when the annular sliding block 535 is located at the lowermost end of the annular sliding groove 522, the lower end of the adapter tube 521 is still inserted into the first annular groove 533, so that the adapter tube 521 can always be in communication with the inner tube 531 during the up-down movement of the annular sliding block 535.

[0069] In order to increase the air tightness between the sliding seat 53 and the transit gas pipe 42, the sliding seat 53 is sleeved with a spring 536. The lower end of the spring 536 is fixedly connected with the sliding seat 53, specifically, a convex ring 532 is fixedly connected at the lower end of the sliding seat 53, the lower end of the spring 536 is fixedly connected to the upper end of the convex ring 532, and the upper end of the spring 536 is fixedly connected with the adapter 52. When the sliding seat 53 is located at the lowermost position, the spring 536 is at least in the original length state, and preferably in the compressed state, so that the sliding seat 53 has a tendency to move away from the adapter 52 under the action of the spring 536, so that the inner tube 531 can be tightly connected with the extension pipe 421.

[0070] In order to realize the automatic operation, the lower end of the joint 52 is fixedly connected with an electromagnet 523, and the sliding seat 53 is fixedly connected with an iron piece 537, which can be an iron sheet or other material that can be attracted by the magnet. The iron piece 537 is arranged opposite to the electromagnet 523. When the electromagnet 523 is powered, a magnetic field is generated to attract the iron piece 537 upward, so that the sliding seat 53 moves to the uppermost position against the elastic force of the spring 536. Therefore, in use, only the on-off control of the electromagnet 523 is needed to cooperate with the spring 536 to realize the up-down movement control of the sliding seat 53, and then realize the automatic connection and automatic separation of the input end and the output end in the adapter assembly 4.

[0071] Further, in order to avoid the interference between the up-down movement of the sliding seat 53 and the rotation of the rotating disc 41 due to operation errors, a pressure sensor 13 is fixedly installed at the upper end of the platform 12, which is located directly below the abutting seat 213, and the pressure sensor 13 is arranged below the carrier disc 3 and in contact with the lower side wall of the carrier disc 3. When the abutting seat 213 acts downward on the compressor, the pressure is transmitted to the pressure sensor 13 through the carrier disc 3.

[0072] It should be noted that the pressure sensor 13 and the electromagnet 523 are both connected to the central controller of the machine body 11. When the pressure value of the pressure sensor 13 is greater than the preset pressure threshold value, the central controller makes the electromagnet 523 de-energized, and when the pressure value of the pressure sensor 13 is less than the preset pressure threshold value, the central controller makes the electromagnet 523 energized.

[0073] According to the different specifications of the compressor, the clamping and fixing pressure of the small compressor is generally 200-500N. In this embodiment, the pressure threshold value of the pressure sensor 13 can be set to 300N.

[0074] That is to say, only when the screw rod 212 is rotated downward to fix the compressor in place by the abutting seat 213, the electromagnet 523 will be de-energized to keep the sliding seat 53 in communication with the intermediate gas pipe 42, and once the abutting seat 213 moves upward and loses the restriction on the compressor, the electromagnet 523 will be immediately energized to move the sliding seat 53 upward and separate from the intermediate gas pipe 42. Since the abutting seat 213 is linked between the pressure sensor 13 and the electromagnet 523, the up-down movement of the sliding seat 53 and the rotation of the rotating disc 41 have a specific sequence, which can avoid the movement interference caused by operation errors.

[0075] The working principle is as follows: in use, first, the compressors to be detected are placed equidistantly on the carrier disc 3, the number of the compressors matches the number of groups of the transfer air pipes 42, so that they can be one-to-one corresponding. Then, the compressor located directly below the abutting seat 213 is communicated with the transfer air pipe 42 close to the abutting seat 213, then the screw rod 212 is rotated, the abutting seat 213 fixes the compressor in place, the pressure sensor 13 detects, the electromagnet 523 is powered off, so that the whole air circuit is turned on, and the detection of the compressor is realized through the machine body 11.

[0076] While the compressor is being detected, the next group of compressors to be detected can be communicated with the corresponding transfer air pipe 42.

[0077] When the detection of the previous group of compressors is completed, the abutting seat 213 is loosened, the air circuit is disconnected, then the rotating disc 41 and the carrier disc 3 can be directly rotated at the same time, then the abutting seat 213 is moved downward again, the next group of compressors is fixed, and the air circuit is communicated.

[0078] While the machine body 11 is monitoring the compressors, the staff can take out the detected compressors and put in new compressors to be detected, and the pipeline of the next group of compressors to be detected is connected again. This cycle can realize the continuous detection of the machine body 11, greatly improving the work efficiency.

[0079] And when the compressor is detected, the abutting seat 213 can fix the compressor, so that the pipeline is not easy to loosen, the air tightness is improved, and the detection accuracy is improved.

[0080] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
