DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] See also Figure 1 , an automatic cleaning device for processing a compression piston of an automobile air conditioner, a connecting rod 80 is rotatably connected to a piston body 8 through a piston pin, a connecting rod bearing 81 is installed at the lower end of the connecting rod 80, and the cleaning device comprises: a base 1, a soaking pool 2 and a flushing receiving pool 3 which are arranged in sequence and closely attached to each other along its length direction are installed on the top of the base 1, a decontamination agent for cleaning dirt on the piston is placed in the soaking pool 2, a support frame 4 which is symmetrically arranged along its width direction and located on both sides of the flushing receiving pool 3 is installed on the top of the base 1, and a high-pressure flushing mechanism 5 is installed between the two support frames 4.

[0035] See also Figure 1 Two sliding seats 6 symmetrically arranged along the width direction are also slidably mounted on the top of the base 1, and a fixing mechanism 7 for fixing the piston is installed between the two sliding seats 6.

[0036] See also Figure 1 , Figure 4 and Figure 8The fixing mechanism 7 includes a rotating cylinder 70, which is rotatably installed between the two sliding seats 6 by supporting a rotating driving group 71. The rotating cylinder 70 is provided with an inner support fixing group 72 for positioning and fixing the piston sleeved thereon. The rotating cylinder 70 is also provided with a locking positioning group 73, which is used to insert one end of a piston pin to lock the position of the piston body 8.

[0037] A plurality of connecting rod bearings 81 are sequentially sleeved on the rotating cylinder 70 and then internally supported and fixed by the internal support fixing group 72, and the locking positioning group 73 is tightly pressed against one end of the piston pin, and the piston body 8 is placed stationary in the decontamination agent in the soaking tank 2. After a certain period of time, the supporting rotation driving group 71 drives the rotating cylinder 70 to rotate 180 degrees, and the piston body 8 is rotated to the top of the rotating cylinder 70, and then the two sliding seats 6 drive the piston body 8 to move to the flushing receiving tank 3.

[0038] See also Figure 1 , Figure 3 and Figure 8 The supporting rotation driving group 71 includes a fixed plate 710 installed on one of the sliding seats 6, an inverted T-shaped groove is provided on the other sliding seat 6, a bracket 711 is slidably connected to the inverted T-shaped groove, the bracket 711 and the inverted T-shaped groove are connected by a push spring 712, the rotating cylinder 70 is rotatably connected to the fixed plate 710, the bracket 711 is provided with a socket 713 that is plugged into the rotating cylinder 70, a bearing sleeve is installed in the socket 713, and a flip driving source that drives the rotating cylinder 70 to rotate 180 degrees is installed on the fixed plate 710.

[0039] Before the connecting rod bearing 81 is mounted on the rotating cylinder 70, the bracket 711 is manually pulled to disengage it from the rotating cylinder 70, so that the connecting rod bearing 81 can be mounted on the rotating cylinder 70. Then, after multiple connecting rod bearings 81 are mounted on the rotating cylinder 70 in sequence, the bracket 711 is released. The bracket 711 is reset and mounted on the rotating cylinder 70 under the elastic force of the push spring 712, thereby supporting the rotating cylinder 70 and preventing the rotating cylinder 70 from being in a cantilever beam state and insufficient supporting force.

[0040] See also Figure 1 and Figure 3 The bracket 711 is provided with a card slot 31, and the flushing receiving pool 3 is provided with a receiving slot 30 flush with the top of the soaking pool 2, the receiving slot 30 is used to cooperate with the card slot 31, and a ball (not shown in the figure) is installed on the card slot 31. When the bracket 711 is mounted on the rotating cylinder 70 through the socket 713, the card slot 31 is stuck on the top of one side of the soaking pool 2. When the sliding seat 6 drives the bracket 711 to move toward the flushing receiving pool 3, the ball in the card slot 31 rolls from the soaking pool 2 to the receiving slot 30, thereby always supporting the bracket 711, further improving the supporting force of the rotating cylinder 70.

[0041] See also Figure 8 and Fig. 9 The inner support fixing group 72 includes a plurality of groups of inner support components slidably connected to the side wall of the rotating cylinder 70 and evenly arranged along its axial direction. Each group of inner support components consists of a plurality of T-shaped inner support plates 720 slidably connected to the side wall of the rotating cylinder 70 and evenly arranged along its circumference, a limit clamp 721 connected to the T-shaped inner support plate 720, and a return spring 722 installed between the T-shaped inner support plate 720 and the inner wall of the rotating cylinder 70. A ball is installed at one end of the T-shaped inner support plate 720 away from the limit clamp 721. A moving rod 723 concentric with the rotating cylinder 70 is slidably connected inside the rotating cylinder 70. A plurality of conical columns 724 evenly arranged along its axial direction are fixedly sleeved on the moving rod 723. A moving driving source (such as a cylinder) for driving the moving rod 723 is installed at one end of the inner wall of the rotating cylinder 70.

[0042] See also Fig. 9 The limit clamp 721 is a U-shaped arc plate having a U-shaped structure when cut along the radial direction of the rotating cylinder 70 .

[0043] After multiple connecting rod bearings 81 are sleeved on the rotating cylinder 70, the connecting rod bearings 81 are moved and placed on the corresponding limiting clamps 721. At this time, the two vertical sections of the limiting clamps 721 located above the axis of the rotating cylinder 70 and perpendicular to the axis of the rotating cylinder 70 preliminarily limit the two sides of the connecting rod bearing 81, so that the T-shaped inner support plate 720 can internally support and fix the corresponding connecting rod bearing 81. Then the moving driving source drives the moving rod 723 to move, and the moving rod 723 drives the conical column 724 to move. When the balls on the T-shaped inner support plate 720 contact the inclined surface of the conical column 724, the conical column 724 pushes the balls to drive the circumferentially arranged T-shaped inner support plate 720 and the limiting clamps 721 to move until the limiting clamps 721 are tightly pressed against the inner wall of the connecting rod bearing 81, thereby achieving the fixation of the connecting rod bearing 81, so that the rotating cylinder 70 can drive the connecting rod 80 and the piston to rotate.

[0044] See also Figure 2 , Figure 4 and Figure 8 The locking positioning group 73 includes a fixed plate 730 slidably mounted on the rotating cylinder 70, and an L-shaped connecting frame 731 is installed on the side wall of the fixed plate 730. The horizontal section of the L-shaped connecting frame 731 parallel to the axis of the rotating cylinder 70 extends toward the bracket 711 and is installed with a plurality of connecting strips 732 evenly arranged along its length direction, and a plug column 733 is installed on the connecting strip 732, and a limiting member is installed on the plug column 733.

[0045] See also Figure 2The limiting member includes a support rod 740 installed on the side wall of the plug column 733, and a V-shaped limiting strip 741 is installed on one end of the support rod 740 away from the plug column 733, and the V-shaped limiting strip 741 is located at one end of the piston body 8.

[0046] After the internal support fixing group 72 fixes the connecting rod bearing 81, the external electric slider drives the fixing plate 730 to drive the L-shaped connecting frame 731, the connecting strip 732 and the plug post 733 to move until the plug post 733 is inserted into the end of the piston pin mounting hole and is tightly pressed against the piston pin. The limit piece limits the rotation of the piston body 8 around the axial direction of the connecting rod bearing 81 to prevent the piston body 8 from rotating along the piston pin under the impact force of water, which affects the flushing and cleaning effect of the piston body 8.

[0047] See also Figure 1 , Figure 4 and Figure 6 The high-pressure flushing mechanism 5 includes a storage dispersion pipe group 51 installed between two support frames 4 through a connecting shaft 50, and a hook-shaped fixed pipe 52 connected to the storage dispersion pipe group 51 is installed at the lower end, and a high-pressure nozzle 53 arranged in sequence from top to bottom is installed on the vertical section of the fixed pipe 52, and a rotating nozzle 54 is installed on the top of the inclined section of the fixed pipe 52, and the fixed pipe 52 corresponds to the piston body 8 one by one.

[0048] See also Figure 4 , Figure 5 and Figure 7 The storage dispersion pipeline group 51 includes a storage tank 510 installed between two connecting shafts 50, and the bottom of the storage tank 510 is equipped with connecting pipes 511 that are evenly arranged along its axial direction and connected to it. The lower end of the connecting pipe 511 is rotatably connected to a rotating disk 512 connected to it, and a rotating drive component that drives multiple rotating disks 512 to rotate synchronously is installed on one of the support frames 4.

[0049] The top of the storage tank 510 is connected to an external water pump, and water is dispersed into the respective rotating disks 512 through the storage tank 510 and the connecting pipe 511, and then transported to the fixed tube 52 through the rotating disk 512. When the rotating cylinder 70 drives the piston body 8 to move as a whole to the top of the rotating cylinder 70, the external electric slider connected to the bottom of the two sliding seats 6 drives the sliding seat 6, the rotating cylinder 70 and the piston body 8 to move toward the flushing receiving pool 3 until the sliding seat 6 and the sliding groove are tightly pressed against one end in the direction of the flushing receiving pool 3. At this time, the piston body 8 is concentric with the rotating disk 512, the vertical section of the fixed tube 52 is located on one side of the outer wall of the piston body 8, and the inclined section of the fixed tube 52 is located below the piston body 8.

[0050] Start the water pump, and water is sprayed from the multiple high-pressure nozzles 53 to the outer wall of the piston body 8 to wash away the dirt on the piston body 8, and the rotating nozzle 54 rotates under the action of water pressure and sprays water on the inner wall of the piston body 8, thereby cleaning the inner wall of the piston body 8, and the rotating drive assembly drives the rotating disk 512 and the fixed tube 52 to rotate along the circumference of the piston body 8, and comprehensively washes and cleans the piston body 8 from multiple angles until the fixed tube 52 conflicts with the locking positioning group 73. During this process, the locking positioning group 73 conflicts with the piston body 8, preventing the piston body 8 from rotating along the piston pin under the impact force of water, affecting the washing and cleaning effect of the piston body 8.

[0051] See also Figure 5 The rotary drive assembly includes a sleeve 520 fixedly connected to the top of the rotating disk 512 and sleeved on the connecting pipe 511, a sprocket is fixedly sleeved on the sleeve 520, and multiple sprockets are connected by chain transmission. A connecting seat 521 is installed on one of the support frames 4, and a driving shaft 522 is rotatably connected to the connecting seat 521. The lower end of the driving shaft 522 and the sleeve 520 adjacent to it are fixedly sleeved with a gear, and the two gears are meshed for transmission.

[0052] The drive shaft 522 is connected to an external drive source (such as a motor). The drive shaft 522 drives the corresponding sleeve 520 to rotate through the meshing transmission of the gears. The sleeve 520 drives the other sleeves 520 to rotate through the meshing transmission of the sprocket chain. The sleeve 520 drives the fixed tube 52 to rotate along the circumference of the piston, thereby comprehensively flushing and cleaning the piston from multiple angles until the fixed tube 52 conflicts with the locking positioning group 73.

[0053] See also Figure 6 and Figure 7 The multiple high-pressure nozzles 53 arranged in sequence from top to bottom are arranged at a downward tilt, so that the impurities washed off when impacting the piston body 8 can fall downward quickly.

[0054] See also Figure 1-Figure 9 When working, multiple connecting rod bearings 81 are sequentially sleeved on the rotating cylinder 70 in such a way that the piston body 8 is located below the axis of the rotating cylinder 70, and then the connecting rod bearings 81 are internally supported and fixed by the internal support fixing group 72, and the locking positioning group 73 is tightly pressed against one end of the piston pin, and the piston body 8 is placed in the decontamination agent in the soaking tank 2. After a certain period of time, the support rotation driving group 71 drives the rotating cylinder 70 to rotate 180 degrees, and rotates the piston body 8 to the top of the rotating cylinder 70 to avoid the accumulation of decontamination agent in the piston body 8, and then the two sliding seats 6 drive the piston body 8 to move to the flushing receiving tank 3.

[0055] Then start the water pump, and water is sprayed from multiple high-pressure nozzles 53 to the outer wall of the piston body 8 to wash away the dirt on the piston body 8. The high-pressure nozzles 53 rotate under the action of water pressure and spray water on the inner wall of the piston body 8, thereby cleaning the inner wall of the piston body 8, and the rotary drive assembly drives the rotating disk 512 and the fixed tube 52 to rotate along the circumference of the piston body 8, and comprehensively washes and cleans the piston body 8 from multiple angles until the fixed tube 52 conflicts with the locking positioning group 73. During this process, the locking positioning group 73 conflicts with the piston body 8 to prevent the piston body 8 from rotating around the piston pin under the impact force of water and affecting the washing and cleaning effect.
