Description

Technical Field

[0001] This utility model relates to the field of shock absorber outer cylinder cleaning, specifically a spray washing machine for shock absorber outer cylinder. Background Technology

[0002] The outer cylinder of a shock absorber is used to suppress the oscillations caused by the spring rebounding after absorbing shocks, as well as impacts from the road surface. Widely used in automobiles, it accelerates the attenuation of vibrations in the chassis and body, thereby improving ride comfort. When driving over uneven roads, although the shock-absorbing spring can filter out road vibrations, the spring itself will still have reciprocating motion; the outer cylinder of the shock absorber is used to suppress this spring bounce.

[0003] During the production of shock absorbers, the outer cylinder needs to be internally cleaned to remove residual impurities. Currently, this cleaning is done manually, with each cylinder being sprayed sequentially. This method is labor-intensive, inefficient, and cannot meet the demands of mass production. Therefore, a new technical solution is needed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a spray washing machine for the outer cylinder of shock absorbers. This solves the technical problem that the current method of manually spraying and washing the outer cylinder of shock absorbers for internal cleaning results in high labor intensity, low work efficiency, and inability to meet the needs of mass production.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A spray washing machine for the outer cylinder of a shock absorber is designed, comprising:

[0006] A cleaning tank, wherein the top and both ends of the cleaning tank are open;

[0007] The switching mechanism includes a bottom plate slidably connected to the openings at both ends of the cleaning tank. Three baffles are fixedly connected to the surface of the bottom plate. The distance between two adjacent baffles is the same as the distance between the two ends of the inner cavity of the tank. Multiple elastic rubber cylinders are provided on the bottom plate between two adjacent baffles.

[0008] A cleaning mechanism includes a connecting plate disposed on the front side of a column. A lifting mechanism is disposed between the column and the connecting plate. Multiple brush rollers are rotatably connected to the bottom of the connecting plate via bearings. The multiple brush rollers correspond to multiple elastic rubber cylinders respectively. The end of each brush roller near the connecting plate rotates through the connecting plate and is connected to the connecting plate by a driving mechanism.

[0009] Preferably, the cleaning mechanism further includes multiple conduits installed at the bottom of the connecting plate, the bottom of each of the multiple conduits being connected to multiple nozzles, a connecting pipe connecting two adjacent conduits, and a water inlet pipe connected to one of the conduits.

[0010] Preferably, the lifting mechanism includes an adjustment groove formed at one end of the column near the connecting plate, an adjustment block slidably connected in the adjustment groove, the surface of the adjustment block being fixedly connected to the connecting plate, a lead screw being rotatably connected between the upper and lower sides of the inner cavity of the adjustment groove via bearings, the adjustment block being threaded onto the outside of the lead screw, and a first drive motor being fixedly installed at the top of the column, the drive end of the first drive motor rotating through the column and connected to the lead screw via a coupling.

[0011] Preferably, the driving mechanism includes a gear fixedly connected to the brush roller and a mounting plate fixedly connected to one end of the connecting plate. A second driving motor is mounted on the bottom of the mounting plate. The driving end of the second driving motor rotatably passes through the mounting plate and is fixedly connected to a driving disk. A connecting shaft is fixedly connected to one side of the surface of the driving disk. A pull rod is rotatably connected to the outside of the connecting shaft via a bearing. A connecting seat is provided at one end of the pull rod. The connecting seat is rotatably connected to the pull rod via a pin. A fixing plate is fixedly connected to the end of the connecting seat away from the pull rod. A rack is connected to the end of the fixing plate near the gear. The rack meshes with the gear. A sliding guide mechanism is provided between the rack and the connecting plate.

[0012] Preferably, the surface of the base plate is provided with a groove, and a filter plate is fixedly connected to the inner cavity of the groove. The surface of the filter plate is on the same horizontal plane as the surface of the base plate, and the elastic rubber cylinder is fixedly connected to the surface of the filter plate. Drainage pipes are connected to one side of both ends of the base plate, and both drainage pipes are in communication with the inner cavity of the groove.

[0013] Preferably, a limiting plate is fixedly connected to the middle of both ends of the base plate, the height of the limiting plate is greater than the thickness of the base plate, and an arc-shaped handle is fixedly connected to one outer end of the limiting plate.

[0016] 1. This utility model combines a brush roller, a connecting plate, a base plate, an elastic rubber cylinder, a lifting mechanism, and a driving mechanism. When the outer cylinder of the shock absorber inside the cleaning chamber is being cleaned, the elastic rubber cylinder on the outer base plate of the cleaning chamber simultaneously loads a new workpiece. After the shock absorber inside the cleaning chamber is cleaned, the work position is changed by shifting the base plate, thus achieving uninterrupted flow operation. This enables alternating and continuous automatic cleaning of the outer cylinder of the shock absorber, effectively reducing labor intensity and further improving the efficiency of cleaning the outer cylinder of the shock absorber.

[0017] 2. By setting up a filter plate, this utility model can direct the wastewater generated during the cleaning of the inner wall of the shock absorber's outer cylinder into the groove, and then discharge it from the groove through the drain pipe, thereby avoiding the accumulation of wastewater generated during the cleaning of the inner wall of the shock absorber's outer cylinder, which would affect the cleaning effect of the inner wall of the shock absorber's outer cylinder.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A spray washing machine for the outer cylinder of a shock absorber, see [link to example]. Figures 1 to 6 The system includes: a cleaning tank 1, wherein the top and both ends of the cleaning tank 1 are open; a switching mechanism, wherein the switching mechanism includes a base plate 2 slidably connected to the openings at both ends of the cleaning tank 1, and three baffles 22 are fixedly connected to the surface of the base plate 2, the distance between two adjacent baffles 22 being the same as the distance between the two ends of the inner cavity of the tank body, and a plurality of elastic rubber cylinders 21 are provided on the base plate 2 between two adjacent baffles 22, the external dimensions of the baffles 22 being adapted to the inner cavity dimensions of the openings at both ends of the cleaning tank 1; and a cleaning mechanism, wherein the cleaning mechanism includes a connecting plate 8 disposed on the front side of the column 5, the column 5 being connected to the connecting plate 8. A lifting mechanism is provided between the connecting plates 8. Multiple brush rollers 81 are rotatably connected to the bottom of the connecting plates 8 via bearings. The multiple brush rollers 81 correspond to multiple elastic rubber cylinders 21 respectively. The end of the brush roller 81 near the connecting plate 8 rotates through the connecting plate 8 and is provided with a driving mechanism between it and the connecting plate 8. The cleaning mechanism also includes multiple conduits 71 installed at the bottom of the connecting plate 8. The bottom of each of the multiple conduits 71 is connected to multiple nozzles 72. A connecting pipe 73 is connected between two adjacent conduits 71. A water inlet pipe 7 is connected to one of the conduits 71.

[0027] During operation, the outer cylinder of the shock absorber to be cleaned is vertically inserted into the elastic rubber cylinder 21. Then, the base plate 2 is pushed to place the installed outer cylinder of the shock absorber into the cleaning tank 1. The lifting mechanism drives the connecting plate 8 to descend, allowing the brush roller 81 to be inserted into the inner cavity of the outer cylinder of the shock absorber. Then, the drive mechanism is activated to drive the brush roller 81 to rotate in the inner cavity of the outer cylinder of the shock absorber, so that the brush roller 81 can brush the inner wall of the outer cylinder of the shock absorber. Then, the water is connected to an external water source through the water inlet pipe 7, so that the cleaning water is sprayed onto the inner wall of the outer cylinder of the shock absorber through the nozzle 72. Combined with the rotation of the brush roller 81, the cleaning effect of the inner wall of the outer cylinder of the shock absorber is improved. The wall cleaning effect is that when the shock absorber is being cleaned, the elastic rubber cylinder 21 on one side of the base plate 2 is placed outside the cleaning box 1. This allows the next shock absorber outer cylinder to be cleaned to be inserted into the elastic rubber cylinder 21 outside the cleaning box 1 while the outer cylinder of the shock absorber is being cleaned. After the shock absorber is cleaned, the base plate 2 is pushed to place the cleaned shock absorber outer cylinder outside the cleaning box 1 for unloading. Then, the next shock absorber outer cylinder to be cleaned is placed inside the cleaning box 1. This allows for alternating and continuous automatic cleaning of the shock absorber outer cylinder, which can effectively reduce labor intensity and further improve the efficiency of cleaning the shock absorber outer cylinder.

[0028] For details, see Figure 1 and Figure 5The lifting mechanism includes an adjustment groove 53 located at one end of the column 5 near the connecting plate 8. An adjustment block 54 is slidably connected within the adjustment groove 53. The surface of the adjustment block 54 is fixedly connected to the connecting plate 8. A lead screw 52 is rotatably connected between the upper and lower sides of the inner cavity of the adjustment groove 53 via bearings. The adjustment block 54 is threaded onto the outer side of the lead screw 52. A first drive motor 51 is fixedly installed on the top of the column 5. The drive end of the first drive motor 51 rotates through the column 5 and is connected to the lead screw 52 via a coupling. By starting the first drive motor 51, the lead screw 52 is driven to rotate, thereby driving the connecting plate 8 to move up and down reciprocally (the up and down reciprocating movement of the connecting plate 8 is achieved by the forward and reverse rotation of the first drive motor 51, and how the motor achieves forward and reverse rotation is existing technology, which will not be elaborated here). This allows the brush roller 81 to be inserted into the outer cylinder of the shock absorber and disengaged from the inner cavity of the outer cylinder of the shock absorber.

[0029] Further, see Figure 1 and Figure 6 The driving mechanism includes a gear 66 fixedly connected to the brush roller 81 and a mounting plate 6 fixedly connected to one end of the connecting plate 8. A second drive motor 68 is mounted on the bottom of the mounting plate 6. The drive end of the second drive motor 68 rotatably passes through the mounting plate 6 and is fixedly connected to a drive disk 61. A connecting shaft 62 is fixedly connected to one side of the surface of the drive disk 61. A pull rod 63 is rotatably connected to the outer side of the connecting shaft 62 via a bearing. A connecting seat 64 is provided at one end of the pull rod 63. The connecting seat 64 is rotatably connected to the pull rod 63 via a pin. A fixing plate 65 is fixedly connected to the end of the connecting seat 64 away from the pull rod 63. A rack 67 is connected to the end of the fixing plate 65 near the gear 66. The rack 67 meshes with the gear 66. A sliding guide mechanism is provided between the rack 67 and the connecting plate 8. The sliding guide mechanism includes a guide groove 69 formed on the surface of the connecting plate 8. A guide block 610 is slidably connected in the guide groove 69, and the guide block 610 is fixedly connected to the bottom of the rack 67. By starting the second drive motor 68, the drive disk 61 is driven to rotate. Since the pull rod 63 is rotatably connected between the connecting seat 64 and the connecting shaft 62, the rack 67 moves within the guide groove 69 guided and limited by the guide block 610. This allows the rotational kinetic energy of the drive disk 61 to be transferred to the linear kinetic energy of the rack 67, thereby driving the rack 67 to move back and forth in a linear motion. In turn, the gear 66 drives the brush roller 81 to rotate on the inner wall of the shock absorber outer cylinder, improving the cleaning effect of the inner wall of the shock absorber outer cylinder.

[0030] It is worth noting that, see Figure 4The base plate 2 has a groove 24 on its surface. A filter plate 23 is fixedly connected to the inner cavity of the groove 24. The surface of the filter plate 23 is on the same horizontal plane as the surface of the base plate 2. The elastic rubber cylinder 21 is fixedly connected to the surface of the filter plate 23. Drain pipes 3 are connected to one side of both ends of the base plate 2. Both drain pipes 3 communicate with the inner cavity of the groove 24. Through the setting of the filter plate 23, the sewage generated during the cleaning of the inner wall of the shock absorber outer cylinder can flow into the groove 24 and then be discharged from the groove 24 through the drain pipes 3. This avoids the accumulation of sewage generated during the cleaning of the inner wall of the shock absorber outer cylinder, which would affect the cleaning effect of the inner wall of the shock absorber outer cylinder.

[0031] It is worth noting that, see Figure 3 Limiting plates 4 are fixedly connected to the middle of both ends of the base plate 2. The height of the limiting plates 4 is greater than the thickness of the base plate 2. An arc-shaped handle 41 is fixedly connected to one outer end of the limiting plates 4. With the setting of the limiting plates 4, when the base plate 2 moves, the limiting plates 4 are limited to the outside of the cleaning tank 1. On the one hand, the movement of the base plate 2 can be limited to ensure that the baffle 22 can be placed at the openings at both ends of the cleaning tank 1. On the other hand, it prevents the base plate 2 from falling out of the cleaning tank 1. In addition, with the arc-shaped handle 41, it is easy for personnel to hold and thus easy for personnel to pull the base plate 2.

[0032] In addition, all components designed in this utility model are general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
