[0002] After the hydraulic pump has been used for a long time, it will wear out, which will affect the use of the hydraulic pump. Therefore, the hydraulic pump needs to be repaired. The hydraulic pump repair requires disassembling the hydraulic pump, replacing the severely worn parts, and then reassembling the hydraulic pump. The assembly of the hydraulic pump requires putting the parts into the 100-housing one by one. During the assembly of the 200-pump liner, the 500-plunger is easy to slip out of the 200-pump liner, so the staff needs to fix the 500-plunger and the 200-pump liner during assembly to prevent the 500-plunger from slipping out. Therefore, the staff's hands need to reach deep into the 100-housing for operation, and the gap between the 100-housing and the 200-pump liner is small, and the edge of the 100-housing has a sharp edge design, which significantly increases the risk of hand injury, causing the operator to be scratched by the edge, posing a potential threat to the safety of the operator.

[0030] The power assembly includes a support frame 101, a drive motor I 102, a slide rail 103, a slider I 104, a connecting ring 105, a slider II 106, a slider III 107 and a connecting plate 108; the workbench 1 is fixedly connected to the support frame 101; the support frame 101 is bolted to the drive motor I 102; the support frame 101 is rotatably connected to the slide rail 103, and the output end of the drive motor I 102 is fixedly connected to the slide rail 103; the slide rail 103 is slidably connected to the slider I 104; the slider I 104 is fixedly connected to the connecting ring 105, and the connecting ring 1 05 is connected to the support ring 2, and the connecting ring 105 is provided with a water storage tank and an air storage tank, the water storage tank is connected to the support ring 2, the water storage tank is connected to the external cleaning liquid delivery device through a water pipe, and the air storage tank is connected to the external air pump through an air pipe; the slide rail 103 is slidably connected to the slider II 106; the slide rail 103 is slidably connected to the slider III 107; the connecting ring 105 is fixedly connected to the connecting plate 108, and the connecting plate 108 is set to be hollow, and the connecting plate 108 is connected to the air storage tank of the connecting ring 105, and the connecting plate 108 is fixedly connected to and connected with the limiting ring 4.

[0031] It also includes a fixed plate I 201, a spring telescopic rod 202, a fixed ring 203, a vibration motor 204 and a bolt knob 205; the power component slider II 106 is fixedly connected to the fixed plate I 201; the fixed plate I 201 is fixedly connected to four spring telescopic rods 202; all the spring telescopic rods 202 are commonly fixedly connected to the fixed ring 203; the fixed ring 203 is fixedly connected to the vibration motor 204; the fixed ring 203 is rotatably connected to four bolt knobs 205.

[0032] The working steps of the above embodiment are: first, the hydraulic pump is placed on the workbench 1, and the hydraulic pump is fixed by the bench vise on the workbench 1, and the cover of the hydraulic pump is facing upward, and then the fixing plate Ⅰ201 and all the parts connected with it are driven downward by the slider Ⅱ106. When the fixing ring 203 moves downward to the same height as the cover of the hydraulic pump, the slider Ⅱ106 stops moving, and then the staff turns the bolt knob 205 so that the bolt knob 205 is in close contact with the cover of the hydraulic pump, thereby fixing the cover of the hydraulic pump, and then the staff The bolts on the hydraulic pump cover are removed, and then the vibration motor 204 is started to vibrate the fixing ring 203 and the bolt knob 205, thereby loosening the hydraulic pump cover and the housing 100. At the same time, the slider Ⅱ106 drives the fixing plate Ⅰ201 to move upward, thereby driving the hydraulic pump cover to move upward, so that the hydraulic pump cover is removed, avoiding the need for the staff to repeatedly knock on the hydraulic pump cover to loosen the hydraulic pump cover and the housing 100 when removing the hydraulic pump cover, which will cause damage to the hydraulic pump cover.

[0033] The staff then removes the hydraulic pump from the fixture of the workbench 1 peripheral device, and then takes out the parts in the housing 100 in turn, then cleans the parts, and replaces the parts that are severely worn or damaged, and then first re-fixes the housing 100 on the fixture of the workbench 1 peripheral device, while the swing seat 300 is fixed on the housing 100. First, apply lubricating oil to the swing seat 300 and the swash plate 400, and then put the swash plate 400 on the swing seat 300, and then assemble the plunger 500, the nine-hole plate 600 and the pump bladder 200, and apply lubricating oil. Then the staff moves the pump bladder 200 and all the parts connected to it to the bottom of the limit ring 4, and then pushes the pump bladder 200 to move upward. When the pump bladder 200 moves upward to the top of the limit ring 4, the air pump connected to the connecting ring 105 inputs air into the air storage tank of the connecting ring 105, and then enters the air bag 5 through the connecting plate 108 and the limit ring 4, so that the air bag 5 expands and becomes as shown in the figure. Figure 4The state shown is shown, so that the pump bladder 200 and the plunger 500 are supported by the air bag 5, so that the pump bladder 200 will not fall and the plunger 500 will not slide out of the pump bladder 200, and then the connecting ring 105 and all the parts connected to it are driven downward by the slider Ⅰ104, thereby driving the pump bladder 200 to move downward. When the limit ring 4 moves downward to contact the swash plate 400, the slider Ⅰ104 stops moving downward, and then the air pump connected to the connecting ring 105 extracts the air in the air bag 5, so that the air bag 5 shrinks, and then the pump bladder 200 flattens the air bag 5, and then the connecting ring 105 is driven upward by the slider Ⅰ104, thereby driving the limit ring 4 and the air bag 5 to move upward. The bladder 5 has been flattened by the pump gall 200, so the airbag 5 follows the limiting ring 4 to move upward between the shell 100 and the pump gall 200 to reset. After the limiting ring 4 and the airbag 5 are reset, the assembly of the parts in the shell 100 is completed, and finally the cover is installed on the shell 100 to complete the assembly of the hydraulic pump; the pump gall 200 and all the parts connected to it are placed in the shell 100 through the limiting ring 4 and the airbag 5, and the plunger 500 is prevented from slipping out of the pump gall 200 by the airbag 5, thereby avoiding the problem that during the assembly process of the pump gall 200, the staff needs to fix the plunger 500 and the pump gall 200 during assembly to prevent the plunger 500 from slipping out, making the staff's hands easily scratched by the edge of the shell 100. Example 2

[0034] On the basis of Example 1, Figure 1 , Figure 4-5 and Figure 6-8 As shown, it also includes a gear ring 301, a gear 302 and a drive motor II 303; the power component connecting ring 105 is rotatably connected to the support ring 2, and the limit rod 3 is slidably connected to the limit ring 4; the support ring 2 is fixedly connected to the gear ring 301; the power component connecting ring 105 is rotatably connected to the gear 302, and the gear 302 is meshed with the gear ring 301; the power component connecting ring 105 is fixedly connected to the drive motor II 303, and the output shaft of the drive motor II 303 is fixedly connected to the gear 302.

[0035] Each limiting rod 3 is provided with a plurality of bristles, and the limiting rod 3 is hollow, and each limiting rod 3 is provided with a plurality of water spray outlets, and the limiting rod 3 is connected with the support ring 2, and the bristles on the limiting rod 3 are used to pre-clean the components in the shell 100.

[0036] It also includes a fixed plate II 401 and a receiving plate 402; the power component slider III 107 is fixedly connected to the fixed plate II 401; the fixed plate II 401 is fixedly connected to the receiving plate 402, and the receiving plate 402 is concentrically arranged with the support ring 2, and the diameter of the receiving plate 402 is smaller than the diameter of the support ring 2, and the fixed plate II 401 is located above the support ring 2, and the pump bladder 200 is supported by the receiving plate 402.

[0037] An electromagnet is arranged inside the limiting ring 4, and the swash plate 400 is sucked by the electromagnet.

[0038] It also includes a water storage frame 411; the workbench 1 is fixedly connected to the water storage frame 411.

[0039] The working steps of the above embodiment are: since a large amount of viscous oil stains will be generated in the hydraulic pump after long-term use, the oil stains in the hydraulic pump will flow out during the disassembly process of the hydraulic pump, polluting the workbench 1, resulting in the need for the staff to clean the workbench 1 later. Therefore, after the cover of the hydraulic pump is disassembled, the staff will turn the bolt knob 205 so that the bolt knob 205 is no longer tightly attached to the cover of the hydraulic pump, and then remove the cover of the hydraulic pump from the fixing ring 203 and the bolt knob 205, and then drive the fixing plate I 201 and all the parts connected to it to move downward through the slider II 106. When the fixing ring 203 moves downward to the middle of the housing 100, the slider II 106 stops moving downward, and then the staff will turn the bolt knob 205 again so that the bolt knob 205 is tightly attached to the housing 100, thereby fixing the housing 100, and loosen the bench vise of the external device on the workbench 1 to release the fixation of the bench vise to the housing 100.

[0040] The slider II 106 drives the fixing ring 203 to move upward, thereby driving the housing 100 and all the parts connected thereto to move upward. When the pump bladder 200 moves upward to contact the receiving plate 402, and the limit ring 4 contacts the swash plate 400, the slider II 106 stops moving upward, and then the driving motor I 102 drives the slide rail 103 and all the parts connected thereto to rotate counterclockwise from the front to the back, thereby driving the housing 100 to rotate. When the housing 100 rotates to the position shown in FIG. Figure 8In the tilted state shown, the driving motor I 102 stops rotating, and the opening of the shell 100 is opposite to the water storage frame 411. Since the oil stains in the shell 100 are relatively viscous, it is difficult for the oil stains in the shell 100 to flow out naturally after the shell 100 rotates. Since the pump gall 200 is supported by the receiving plate 402, the pump gall 200 will not flow out of the shell 100. Then, the gear 302 is driven to rotate by the driving motor II 303, and the gear 302 drives the gear ring 301 and all the parts connected to it to rotate, so that the limit rod 3 rotates around the connecting ring 105, and then the cleaning liquid delivery device connected to the limit rod 3 is connected to the water storage tank of the connecting ring 105. The cleaning liquid is input into the housing 100, and then input into the limiting rod 3 through the support ring 2, and finally sprayed out from the water spray port of the limiting rod 3, so that the housing 100 and the pump chamber 200 are cleaned by the rotation of the limiting rod 3, so that the oil stains in the housing 100 are diluted and flushed out, and since the housing 100 is tilted downward, the cleaning liquid and oil stains in the housing 100 will flow out of the housing 100, and then fall into the water storage frame 411, thereby completing the pre-cleaning of the parts in the housing 100, reducing the difficulty of subsequent cleaning, and avoiding the oil stains in the hydraulic pump from flowing out and contaminating the workbench 1, resulting in the need for staff to clean the workbench 1 later.

[0041] When the pre-cleaning is completed, the electromagnet inside the limit ring 4 is activated to attract the swash plate 400, so that the swash plate 400 will not fall after the subsequent movement of the housing 100, and then the slider II 106 drives the fixing plate I 201 to move rightward, thereby driving the fixing ring 203 and the housing 100 to move rightward. Since the housing 100 is in a downward tilted state, the pump bladder 200 will not move with the housing 100. When the housing 100 moves rightward to the right end of the slide rail 103, the slider II 106 stops moving. Since the pump 200 is in a downwardly tilted state and the plunger 500 is located at one end above the pump 200, the plunger 500 will not slide out of the pump 200 and the nine-hole plate 600 will not fall out. Then, the air pump connected to the connecting ring 105 inputs air into the airbag 5 to expand the airbag 5, thereby cooperating with the limiting rod 3 and the limiting ring 4 to limit the pump 200, the plunger 500 and the nine-hole plate 600, and then the driving motor I 102 drives the slide rail 103 and all the parts connected thereto to reset and rotate. , when the slide rail 103 is reset, the pump 200, the plunger 500 and the nine-hole plate 600 are limited by the limit rod 3, the limit ring 4 and the air bag 5, so the pump 200, the plunger 500 and the nine-hole plate 600 will not fall, and the inclined plate 400 will not fall because it is sucked by the electromagnet. The staff first holds the inclined plate 400, closes the electromagnet inside the limit ring 4, and removes the inclined plate 400 from the limit ring 4. Then, after the staff holds the pump 200, the air pump connected to the connecting ring 105 is The air in the airbag 5 is extracted to shrink the airbag 5, and then the staff holds the pump bladder 200 and moves it downward, thereby removing the pump bladder 200, the plunger 500 and the nine-hole plate 600 from the shell 100 as a whole, thereby avoiding the prior art that when the pump bladder 200, the plunger 500 and the nine-hole plate 600 are poured out of the shell 100, the pump bladder 200, the plunger 500 and the nine-hole plate 600 are directly scattered, causing the pump bladder 200, the plunger 500 and the nine-hole plate 600 to collide with each other and cause damage to parts. Example 3

[0042] On the basis of Example 2, Figure 5-7 As shown, it also includes an elastic metal sheet 501; all the limiting rods 3 are fixedly connected with an elastic metal sheet 501. When the pump chamber 200 is located between several limiting rods 3, the elastic metal sheet 501 is located between the pump chamber 200 and the nine-hole plate 600, and the nine-hole plate 600 is limited by the elastic metal sheet 501.

[0043] It also includes a rotating sleeve 502 and a cleaning plate 503; all the limit rods 3 are rotatably connected to a rotating sleeve 502 through a torsion spring, and a plurality of bristles are arranged on the surface of the rotating sleeve 502; all the rotating sleeves 502 are fixedly connected to a cleaning plate 503, and a plurality of bristles are arranged on the cleaning plate 503, and the piston 500 is cleaned by the cleaning plate 503.

[0044] The lower end of the cleaning plate 503 is provided with a bevel.

[0045] The working steps of the above embodiment are: since there will be a lot of viscous oil stains between the pump chamber 200 and the plunger 500, after the subsequent staff pulls the plunger 500 out of the pump chamber 200, the oil stains will flow out of the pump chamber 200 onto the staff's hands. In order to avoid contaminating the parts of the hydraulic pump, the subsequent staff needs to spend time to clean the oil stains on their hands and then assemble the clean hydraulic pump parts. Therefore, when the limit rod 3 rotates to clean the housing 100 and the pump chamber 200 for a period of time, After that, the slider III 107 drives the fixing plate II 401 and the receiving plate 402 to move to the left. Since the housing 100 and the pump bladder 200 are in a downwardly inclined state, after the receiving plate 402 moves to the left, the pump bladder 200 will move to the left along with the receiving plate 402. It should be noted that, in the process of the inclined plate 400 moving upward to contact with the limiting ring 4, when the pump bladder 200 passes the limiting rod 3, the pump bladder 200 squeezes the elastic metal sheet 501, so that the elastic metal sheet 501 is compressed. When the inclined plate 400 moves upward to contact with the limiting ring 4, the pump bladder 200 squeezes the elastic metal sheet 501, so that the elastic metal sheet 501 is compressed. When the piston 500 contacts the limiting ring 4, the elastic metal sheet 501 is located between the pump 200 and the nine-hole plate 600, and then the elastic metal sheet 501 is reset and popped out to limit the nine-hole plate 600, so that when the pump 200 moves to the left, the nine-hole plate 600 and the plunger 500 cannot move to the left with the pump 200, so that the part of the plunger 500 located inside the pump 200 is exposed. When the length of the plunger 500 located in the pump 200 is one centimeter, the slider III 107 stops moving, and in the embodiment In the process of the slider II 106 driving the housing 100 and the pump bladder 200 to move upward, since the lower end of the cleaning plate 503 is provided with a bevel, when the pump bladder 200 passes through the cleaning plate 503, the pump bladder 200 squeezes the bevel of the cleaning plate 503, and under the guidance of the bevel of the cleaning plate 503, the cleaning plate 503 and the rotating sleeve 502 rotate outward, and the torsion spring connecting the cleaning plate 503 and the rotating sleeve 502 is compressed, so the cleaning plate 503 will not hinder the rise of the pump bladder 200;Subsequently, when the slider III 107 drives the receiving plate 402 to move to the left, and the pump chamber 200 follows the receiving plate 402 to move to the left, the part of the plunger 500 located inside the pump chamber 200 is exposed. At this time, the cleaning plate 503 is directly opposite to the exposed position of the plunger 500, and the cleaning plate 503 is no longer restricted by the pump chamber 200. Then, the torsion spring recovery part connected to the cleaning plate 503 and the rotating sleeve 502 is twisted, driving the cleaning plate 503 to rotate inward, so that the cleaning plate 503 and the plunger 500 are tightly attached, so that in the subsequent rotation of the limit rod 3, the plunger 500 is cleaned by the bristles on the cleaning plate 503, so that there is no oil stain between the pump chamber 200 and the plunger 500, and then after the cleaning is completed, the cleaning plate 503 is cleaned by the bristles on the cleaning plate 503. The slider III 107 drives the fixing plate II 401 to move rightward, thereby pushing the pump bladder 200 into the housing 100 again, so that the pump bladder 200 and the plunger 500 are matched together again, and then when the subsequent staff lifts the pump bladder 200 to move out from the limiting ring 4, the pump bladder 200 contacts the elastic metal sheet 501 and moves relatively, at this time, the pump bladder 200 squeezes and deforms the elastic metal sheet 501, and then when the pump bladder 200 and the elastic metal sheet 501 are separated, the elastic metal sheet 501 is restored to its original shape, and the plunger 500 is cleaned by the bristles on the limiting rod 3, thereby avoiding the problem that the oil stains will flow out of the pump bladder 200 to the hands of the staff after the staff pulls the plunger 500 out of the pump bladder 200. ;

[0046] Although the present invention is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principle and spirit of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the present invention, but the scope of protection is limited by the content of the claims.
