Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts detection equipment, and in particular relates to a maintenance equipment for automobile air-conditioning compressor. Background Art

[0002] The automotive air conditioning compressor is the core component of the air conditioning system, responsible for compressing low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas to achieve 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 will not only affect the performance of the air conditioning system, but also reduce the driving experience. Therefore, it is particularly important to regularly inspect and maintain the compressor.

[0003] At present, the automotive air-conditioning compressor maintenance equipment on the market is mainly divided into two categories: manual tools and automated testing equipment. Among them, manual tools include wrenches, pressure gauges, vacuum pumps, etc.; these tools are low-cost and easy to operate, but rely on the experience and skills of technicians, and are prone to misjudgment and missed detection. Automated testing equipment can achieve pressure testing, current detection, temperature monitoring, etc.

[0004] At present, when using automated testing equipment for pressure testing, there is a lack of effective means to fix the compressor. When high-pressure air is introduced into the compressor, it will cause the compressor to vibrate, which will cause the pipeline to loosen, leak, or even fall off, affecting the final maintenance effect.

[0005] Therefore, we propose a maintenance equipment for automobile air-conditioning compressor to solve the above problems. Summary of the invention

The upper end of the docking joint is connected to the air source of the body for the input end, and the lower end of the docking joint is movably connected with a sliding seat, which can slide in the vertical direction, and the upper end of the sliding seat is always connected with the lower end of the docking joint; When the sliding seat is located at the uppermost position, the sliding seat is separated from the intermediate transfer air pipe below, and when the sliding seat is located at the lowermost position, the sliding seat is connected to the intermediate transfer air pipe below.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] As one of the purposes of the present invention, in order to solve the problem in the prior art that the air-conditioning compressor is not fixed in place during maintenance, which easily leads to loose pipes and thus causes inaccurate detection results, the following technical solution is adopted: like Figure 1-Figure 10As shown, a maintenance device for automobile air-conditioning compressor includes a base 1, and a body 11 is installed on the upper end of the base 1. The body 11 is provided with a switch button, a power indicator light, a high-voltage indicator light, a fault indicator light, a control panel, a USB port, etc. A platform 12 for placing the compressor is installed on one side of the body 11. The upper end of the platform 12 is a horizontal table. A fixing frame 2 is fixedly installed on the upper end of the platform 12. The fixing frame 2 is a gantry frame. 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 to the upper end of the platform 12 to avoid vibration of the compressor during operation, which may cause the position of the compressor to shift and cause the pipe joint to loosen.

[0024] The specific introduction of the fixing mechanism 21 is as follows: The fixing mechanism 21 includes a nut seat 211, which 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. The nut seat 211 is internally threadedly connected with a screw rod 212, and the lower end of the screw rod 212 is arranged through the through hole. A tightening seat 213 is installed at the lower end of the screw rod 212, and the tightening seat 213 is fixedly or rotationally connected to the bottom of the screw rod 212. In order to reduce friction, the connection method between the tightening seat 213 and the screw rod 212 is preferably a rotational connection. The tightening seat 213 is moved closer to or away from the platform 12 by rotating the screw rod 212, thereby fixing or releasing the compressor.

[0025] As a further optimization, a rotating handle 214 is fixedly connected to the upper end of the screw rod 212, so that the operator can rotate the screw rod 212 by controlling the rotating handle 214, which saves effort and reduces the difficulty of operation.

[0026] In order to realize continuous loading of the compressor, reduce the time of moving the compressor up and down, and enable the machine body 11 to work continuously, the present device also includes a loading tray 3, which is installed at the upper end of the platform 12, and the loading tray 3 is horizontally arranged. The center of the loading tray 3 is rotatably connected to the platform 12, so that the loading tray 3 can rotate along the vertical center line. At the same time, a part of the loading tray 3 is located directly below the fixing mechanism 21, specifically, the part of the loading tray 3 close to the edge. When the loading tray 3 rotates, the compressor can be transported to the fixing mechanism 21. In actual work, multiple compressors to be repaired can be placed equidistantly on the loading tray 3. When the detection of the previous compressor is completed, the loading tray is rotated to realize the rapid detection of the next compressor. Compared with the operation method in the prior art, which requires moving the previous compressor away and then moving the next compressor in, it can save time and improve the maintenance efficiency.

[0027] In order to save time for connecting and disassembling the compressor pipeline and improve efficiency from the pipeline assembly and disassembly aspect, the device also includes a switching assembly 4, which has an input end and multiple output ends, the input end is connected to the air source of the body 11, and the output end is used to connect to the air pipe of the compressor. When 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, it is only necessary to adjust the connection line between the input end and the corresponding output end to achieve the switching of the pipeline. Compared with the operation mode in the prior art that the pipeline of the previous compressor must be removed and the pipeline of the next compressor must be connected, this embodiment can use the maintenance time to achieve the disassembly and assembly of the pipeline, thereby saving time and improving efficiency.

[0028] In order to make the continuous loading of the compressor and the pipeline connection of the compressor cooperate with each other, the adapter assembly 4 is rotatably installed on the platform 12, and the loading plate 3 and the adapter assembly 4 are connected by a transmission assembly. When the loading plate 3 rotates, the adapter assembly 4 will rotate synchronously, so that the handling station on the loading plate 3 and the pipeline connection station on the adapter assembly 4 can be switched synchronously, thereby further improving the work efficiency of compressor maintenance.

[0029] At the same time, in order to avoid the intersection of the connected pipes, the difficulty of pipe connection is increased. In this embodiment, the transmission assembly includes a driving gear 431 and a driven gear 31, wherein the driving gear 431 is driven by a servo motor installed inside the body 11. The driving gear 431 and the driven gear 31 are respectively fixedly connected at the center of the adapter assembly 4 and the loading plate 3, and the driving gear 431 and the driven gear 31 rotate synchronously in opposite directions, so that the multiple compressors on the loading plate 3 and the multiple output ends on the adapter assembly 4 correspond one to one. In other words, the above-mentioned handling stations and pipeline connection stations are matched one to one, and there is no intersection, so that the pipeline can be disassembled and assembled more conveniently.

[0030] In addition, since the loading tray 3 and the adapter assembly 4 are driven by gear meshing, when the abutment seat 213 presses and fixes the compressor and the loading tray 3, the adapter assembly 4 will also be fixed, thereby improving stability.

[0031] Furthermore, for practical installation considerations, the driving gear 431 and the driven gear 31 are transmitted through the gear set 32, and the number of gears in the gear set 32 ​​is an even number, so that the driving gear 431 and the driven gear 31 keep synchronously rotating 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 angles of the adapter assembly 4 and the loading tray 3 can be kept consistent.

[0032] The specific introduction of the adapter component 4 is as follows: 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 the rotating shaft 43. The lower end of the rotating shaft 43 passes through the platform 12 and is fixedly connected to the driving gear 431. The fixed plate 51 is fixedly connected to the side wall of the body 11, and the fixed plate 51 is located directly above the rotating disk 41.

[0033] In order to improve stability, a support shaft 44 is rotatably connected between the rotating disk 41 and the fixed plate 51, so that the structure of the fixed plate 51 and the rotating disk 41 is more stable.

[0034] The output end of the adapter assembly 4 includes a transfer air pipe 42. A plurality of transfer air pipes 42 are arranged in an array around the central circumference of the rotating disk 41. Each transfer air pipe 42 includes a high-pressure pipe and a low-pressure pipe. The output end of the transfer air pipe 42 is connected to the air pipe of the compressor.

[0035] The input end of the adapter assembly 4 includes two sets of docking joints 52, which are fixedly mounted on the fixed plate 51, and the two pairs of joints 52 are matched and corresponded to the positions of the high-pressure pipe and the low-pressure pipe respectively. The upper end of the docking joint 52 is the input end and is connected to the gas source of the body 11. Specifically, the two are connected through the connecting pipe 6. The lower end of the docking joint 52 is movably connected with a sliding seat 53, which can slide in the vertical direction, and the upper end of the sliding seat 53 is always connected to the lower end of the docking joint 52. In other words, the connection or separation of the docking joint 52 and the transfer air pipe 42 is achieved by the up and down movement of the sliding seat 53.

[0036] When the sliding seat 53 is at the uppermost position, the sliding seat 53 is separated from the intermediate air pipe 42 below, so that the rotating disk 41 below can rotate normally. When the sliding seat 53 is at the lowermost position, the sliding seat 53 is connected to the intermediate air pipe 42 below.

[0037] The sliding seat 53 has an inner tube 531 , and the sliding seat 53 is cylindrical as a whole. The inner tube 531 is concentrically arranged with the sliding seat 53 . A first annular groove 533 is arranged at the upper end of the sliding seat 53 , and a second annular groove 534 is arranged at the lower end of the sliding seat 53 . Both the first annular groove 533 and the second annular groove 534 are concentrically arranged with the inner tube 531 .

[0038] A docking tube 521 is provided at the lower end of the docking head 52 . The docking tube 521 is inserted into the first annular groove 533 , and the inner wall of the docking tube 521 is tightly fitted with the outer wall of the inner tube 531 .

[0039] An extension tube 421 is disposed at the upper end of the transit air pipe 42 . The extension tube 421 can be inserted into and pulled out of the second annular groove 534 , and the inner wall of the extension tube 421 is tightly fitted with the outer wall of the inner tube 531 .

[0040] The upper end of the docking joint 52 has an inlet end 524, and the two ends of the connecting pipe 6 are respectively connected to the gas source of the body 11 and the inlet end 524. The gas enters the transit air pipe 42 along the docking joint 52, the docking tube 521, the inner tube 531, and the extension tube 421, and then the input end of the transit air pipe 42 is connected to the air pipe of the compressor through another section of the pipe, thereby realizing the connection of the entire pipeline.

[0041] In order to prevent the sliding seat 53 from falling off from the docking joint 52 and to limit the up and down displacement range of the sliding seat 53, an annular groove 522 is provided at the lower end of the docking joint 52, and an annular slider 535 is fixedly connected to the upper end of the sliding seat 53, and the annular slider 535 is slidably set in the annular groove 522.

[0042] It should be noted that the depth of the first annular groove 533 is greater than the depth of the annular groove 522. When the annular slider 535 is located at the lowermost end of the annular groove 522, the lower end of the docking tube 521 is still inserted in the first annular groove 533, so that when the annular slider 535 moves up and down, the docking tube 521 can always remain connected with the inner tube 531.

[0043] In order to increase the airtightness between the sliding seat 53 and the transfer air pipe 42, a spring 536 is provided on the outer sleeve of the sliding seat 53. The lower end of the spring 536 is fixedly connected to the sliding seat 53. Specifically, a convex ring 532 is fixedly connected to 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 to the docking head 52. When the sliding seat 53 is at the lowest position, the spring 536 is at least kept in the original length, and is preferably in a compressed state, so that under the action of the spring 536, the sliding seat 53 has a tendency to move away from the docking head 52, so that the inner tube 531 can be closely connected to the extension tube 421.

[0044] 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 made of iron sheet or other materials that can be attracted by magnets, and the iron piece 537 and the electromagnet 523 are arranged opposite to each other. When the electromagnet 523 is energized, it can generate a magnetic field that attracts the iron piece 537 upward, so that the sliding seat 53 overcomes the elastic force of the spring 536 and moves to the uppermost position. Therefore, when in use, it is only necessary to control the on and off of the electromagnet 523 to cooperate with the spring 536 to realize the up and down movement control of the sliding seat 53, thereby realizing the automatic connection and separation of the input end and the output end in the adapter assembly 4.

[0045] Furthermore, in order to avoid interference between the up and down movement of the sliding seat 53 and the rotation of the rotating disk 41 due to operational errors, a pressure sensor 13 is fixedly installed on the upper end of the platform 12. The pressure sensor 13 is located directly below the abutment seat 213, and the pressure sensor 13 is arranged below the loading plate 3 and contacts the lower side wall of the loading plate 3. When the abutment seat 213 acts downward on the compressor, the pressure will be transmitted to the pressure sensor 13 through the loading plate 3.

[0046] It should be noted that the pressure sensor 13 and the electromagnet 523 are both connected to the central controller of the body 11. When the pressure value of the pressure sensor 13 is greater than the preset pressure threshold, the central controller cuts off the power to the electromagnet 523. When the pressure value of the pressure sensor 13 is less than the preset pressure threshold, the central controller turns on the power to the electromagnet 523.

[0047] According to different specifications of the compressor, the clamping and fixing pressure for a small compressor is generally 200-500N. In this embodiment, the pressure threshold of the pressure sensor 13 can be set at 300N.

[0048] That is, only when the screw 212 rotates downward and the abutting seat 213 fixes the compressor in place, the electromagnet 523 will be powered off, so that the sliding seat 53 remains connected to the transfer air pipe 42. Once the abutting seat 213 moves upward and loses the restriction on the compressor, the electromagnet 523 will be powered on immediately, so that the sliding seat 53 moves upward and separates from the transfer air pipe 42. Since the abutting seat 213 is linked to the electromagnet 523 through the pressure sensor 13, the up and down movement of the sliding seat 53 and the rotation of the rotating disk 41 can be in a specific order, thereby avoiding motion interference caused by operating errors.

[0049] The working principle is as follows: when in use, first place the compressors to be tested on the loading plate 3 at equal distances, and match the number of compressors with the number of groups of transfer air pipes 42 so that the two can correspond one to one. Then, connect the compressor directly below the abutment seat 213 to the transfer air pipe 42 close to the abutment seat 213, and then rotate the screw 212 so that the abutment seat 213 fixes the compressor in place. After detection by the pressure sensor 13, the electromagnet 523 is de-energized, thereby connecting the entire air path, and the compressor is detected through the machine body 11.

[0050] While the compressor is being tested, the next group of compressors to be tested may be connected to the corresponding transfer air pipes 42 .

[0051] When the inspection of the previous set of compressors is completed, the abutment seat 213 is released to disconnect the gas path, and then the rotating disk 41 and the loading disk 3 can be directly rotated at the same time, and then the abutment seat 213 is moved downward again to fix the new set of compressors and connect the gas path.

[0052] While the machine body 11 is monitoring the compressor, the staff can remove the compressor that has been tested, put in a new compressor to be tested, and reconnect the pipelines of the next set of compressors to be tested. This cycle can achieve continuous testing of the machine body 11, greatly improving work efficiency.

[0053] Furthermore, when the compressor is tested, the abutment seat 213 can fix the compressor, so that the pipeline is not likely to become loose, thereby improving the air tightness and the accuracy of the test.

[0054] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
