Description

Technical Field

[0001] The present application relates to the field of part processing equipment, and in particular, to a high-pressure cleaning equipment. Background Art

[0002] The high-pressure cleaning equipment generates high pressure through a power device, drives a high-pressure plunger pump to pressurize ordinary tap water to an extremely high pressure, and then sprays it out in the form of a high-speed jet through a special nozzle to form a water column with a strong impact force, flushing the fine chips generated by turning on the surface of the part, so as to achieve efficient cleaning of the part.

[0003] In the prior art, the nozzle is usually fixed on the surface of the high-pressure cleaning equipment. When the part is clamped and fixed on the surface of the high-pressure cleaning equipment, the nozzle can only drive the water column to concentrate on impacting a local surface of the part, and it is necessary for the staff to adjust the position of the part on the high-pressure cleaning equipment, increasing the cleaning steps of the part, prolonging the processing cycle of the part, and thus increasing the processing cost of the part. Summary of the Invention

[0004] In order to improve the problem of the processing cost of the part, the present application provides a high-pressure cleaning equipment.

[0005] A high-pressure cleaning equipment provided by the present application adopts the following technical solutions: A high-pressure cleaning equipment includes a seat body, a clamping device and a cleaning device. The seat body has a cleaning cavity, and a door body for closing the cleaning cavity is slidably connected to the inner wall of the cleaning cavity. The clamping device includes a sliding seat, a clamping seat and a clamping component. The sliding seat is slidably connected to the inner wall of the cleaning cavity, and the sliding direction of the sliding seat is parallel to the length direction of the seat body. The clamping seat is slidably connected to the surface of the sliding seat, and the sliding direction of the clamping seat is parallel to the width direction of the seat body. The clamping component is connected to the surface of the clamping seat, and the clamping component can clamp and fix the part on the surface of the clamping seat. The cleaning device includes a nozzle and an adjusting seat. The adjusting seat is slidably connected to the inner wall of the cleaning cavity, and the sliding direction of the adjusting seat is parallel to the height direction of the seat body. The nozzle is connected to the adjusting seat, and the water outlet end of the nozzle faces the surface of the clamping seat.

[0006] By adopting the above technical solution, the clamping assembly clamps and fixes the turned parts on the surface of the clamping seat, the water outlet of the nozzle faces the surface of the part to be cleaned, and the high-pressure water column is sprayed on the surface of the part to be cleaned through the water outlet of the nozzle, removing impurities adhered to the surface of the part during turning, thereby achieving efficient cleaning of the surface of the part to be cleaned; at the same time, the sliding seat is driven to slide on the inner wall of the cleaning chamber, so that the other surfaces of the part to be cleaned are close to the water outlet of the nozzle, and the clamping seat slides on the surface of the sliding seat, so that the other surfaces of the part to be cleaned face the water outlet of the nozzle, thereby achieving automatic impact cleaning of the various surfaces of the part to be cleaned by the nozzle, without the need for staff to remove the parts from the clamping assembly and adjust the direction, reducing the cleaning steps of the parts, shortening the processing cycle of the parts, and thus reducing the processing cost of the parts; at the same time, the adjustment seat is slidably connected to the inner wall of the cleaning chamber, adjusting the distance between the water outlet of the nozzle and the surface of the part to be processed, thereby ensuring that the water flow impacts the surface of the part at an appropriate angle and speed, thereby improving the cleaning efficiency of the part surface.

[0007] Optionally, the clamping assembly includes multiple clamping plates, multiple rotating cylinders and multiple groups of positioning members, multiple groups of positioning members are connected at intervals on the surface of the clamping seat facing the nozzle, the arrangement direction of the positioning members and the length direction of the seat body are parallel to each other, each group of positioning members includes multiple positioning strips, multiple positioning strips are connected at intervals on the surface of the clamping seat, positioning spaces for parts to be embedded are left between the multiple positioning strips, and the surfaces of the positioning strips facing the positioning spaces are provided with positioning grooves for part ends to be embedded, the inner walls of the positioning grooves abut the surfaces of the positioning strips to form positioning, and multiple rotating cylinders are connected at intervals on the surface of the clamping seat, the rotating cylinders are located one-to-one between two adjacent groups of positioning members, the clamping plates are fixed one-to-one on the piston rods of the rotating cylinders, and when the part is embedded in the positioning space and the end parts of the part are embedded one-to-one in the positioning grooves, the rotating cylinders drive the clamping plates to rotate in the direction close to the part, and the inner walls of the positioning grooves and the clamping plate surfaces clamp the two ends of the part to form positioning.

[0008] By adopting the above technical solution, when the part is embedded in the positioning space and the positioning end portions are embedded in the positioning grooves one by one, the inner wall of the positioning groove abuts against the end face of the part to form a positioning, so that the part is not easy to slip on the surface of the clamping seat when impacted by water flow, thereby improving the limiting stability of the part on the surface of the clamping seat; at the same time, the rotating cylinder drives the clamping plate to rotate in the direction close to the part, and the clamping plate surface and the inner wall of the positioning groove clamp the two sides of the part to form a limit, so that the part is not easy to leave the positioning groove, thereby improving the stability of the part in the positioning space, thereby ensuring the stability of the water column impacting the surface of the part for cleaning.

[0009] Optionally, the cleaning device further includes a water supply assembly, which includes a water tank, a first pump body, a second pump body, and a filter. A drainage cavity is formed on the side wall of the clamping seat. A plurality of drainage holes are spaced apart on the inner wall of the drainage cavity close to the clamping assembly. The drainage holes penetrate the surface of the clamping seat. A drainage channel is formed on the inner wall of the cleaning cavity, and the drainage channel penetrates the surface of the seat body. The filter is connected to the surface of the seat body facing the drainage channel. The water in the cleaning cavity enters the filter through the drainage channel. The filter can filter the water. The first pump body, the water tank, and the second pump body are spaced and connected to the surface of the seat body. The water inlet end of the first pump body is communicated with the water outlet end of the filter through a pipeline. The water outlet end of the first pump body is communicated with the inner cavity of the water tank through a pipeline. The water inlet end of the second pump body is communicated with the inner cavity of the water tank through a pipeline. The water outlet end of the second pump body is communicated with the water inlet end of the nozzle through a pipeline.

[0010] By adopting the above technical solution, the water in the water tank is pressurized by the pump body and sprayed from the water outlet end of the nozzle onto the surface of the part, realizing the cleaning of the part surface; at the same time, the water impacting the part surface enters the cleaning cavity bottom wall from the drainage cavity through the drainage holes. The accumulated water flow in the cleaning cavity enters the filter through the drainage channel. The filter can filter the discharged water. The second pump body returns the filtered water in the filter to the water tank through a pipeline, realizing the recycling of water resources and reducing the consumption of resources, thereby reflecting the concept of environmental protection.

[0011] Optionally, it further includes a demisting assembly, which includes an oil mist purifier and a demisting pipeline. One end of the demisting pipeline is connected to the seat body and communicated with the cleaning cavity. The other end of the demisting pipeline is connected to the driving end of the oil mist purifier. The oil mist purifier sucks the oil mist in the cleaning cavity through the demisting pipeline.

[0012] By adopting the above technical solution, when multiple parts are respectively embedded in multiple positioning spaces, the door body is driven to slide on the inner wall of the cleaning cavity to close the cleaning cavity. When the high-pressure water column sprayed from the water outlet end of the nozzle impacts the part surface, a violent impact occurs between the water column and the part surface. This impact breaks the water column into fine droplets. The droplets floating in the air carry the oil droplets on the part surface to form oil mist. The oil mist purifier sucks the oil mist in the cleaning cavity through the demisting pipeline, realizing the treatment of the oil mist in the cleaning cavity, enabling the staff to observe the cleaning situation of the parts in the cleaning cavity through the perspective lens on the door body, and thus further improving the cleaning efficiency of the parts.

[0013] Optionally, the filter includes a filter base, a plurality of filter plates, and a plurality of positioning boxes. The filter base is connected to the surface of the seat body facing the drainage channel. A filter cavity is formed on the surface of the filter base facing the drainage channel. One water inlet end of the pump body is connected to the filter cavity through a pipeline. A plurality of sliding cavities for the positioning boxes to slide are formed at intervals on the inner wall of the filter cavity. The arrangement direction of the sliding cavities is parallel to the height direction of the seat body. A plurality of sieve holes are formed at intervals on the bottom wall of the positioning box, and the sieve holes penetrate the surface of the positioning box. The water in the drainage channel enters the inner cavity of the adjacent positioning box through the sieve holes from the inner cavity of the positioning box. The filter plates are respectively embedded into the inner cavities of the positioning boxes, and the filter plates can filter the water in the positioning boxes.

[0014] By adopting the above technical solution, the filter plates are respectively embedded into the inner cavities of the positioning boxes. When the water in the cleaning cavity enters the inner cavity of the positioning box through the drainage channel, the filter plates filter the water in the positioning box and then enter the inner cavity of the adjacent positioning box through the sieve holes, realizing multi-stage filtration of water. The water after multi-stage filtration accumulates in the filter cavity, and the pump body returns the water in the filter cavity to the water tank through a pipeline, realizing the recycling of water resources and reducing the waste of water resources.

[0015] Optionally, the filter base is connected with a limiting component, which includes a limiting plate and a first elastic member. A limiting cavity for the limiting plate to slide is formed on the surface of the filter base. The sliding direction of the limiting plate is perpendicular to the sliding direction of the positioning box. The limiting cavity communicates with a plurality of sliding cavities. One end of the first elastic member in the direction of its elastic force is connected to the inner wall of the limiting cavity, and the other end of the first elastic member in the direction of its elastic force is connected to the plate surface of the limiting plate. The first elastic member has an elastic force to drive the limiting plate to slide towards the direction close to the sliding cavity, and the plate surface of the limiting plate and the inner wall of the sliding cavity clamp both ends of the positioning box to form a limit.

[0016] By adopting the above technical solution, when the positioning box is installed, the limiting plate is driven to slide away from the sliding cavity against the elastic force of the first elastic member, and the plate surface of the limiting plate is flush with the inner wall of the sliding cavity. Then, the positioning box is driven to be embedded into the sliding cavity, and the end face of the positioning box is flush with the inner wall of the sliding cavity. After releasing the limiting plate, the elastic force of the first elastic member drives the limiting plate to slide towards the direction close to the sliding cavity, and the plate surface of the limiting plate and the inner wall of the sliding cavity clamp both ends of the positioning box to form a limit, making the positioning box not easy to shift in the sliding cavity, thereby improving the limiting stability of the positioning box in the sliding cavity.

[0017] Optionally, the limiting component further includes a limiting piston, a power piston, and a second elastic member. A power flow channel for the power piston to slide is provided on the inner wall of the sliding cavity. The sliding direction of the power piston is parallel to the sliding direction of the positioning box. The power flow channel communicates with the limiting cavity. The limiting piston is slidably connected to the inner wall of the power flow channel close to the limiting cavity. The sliding direction of the limiting piston is parallel to the sliding direction of the power piston. An embedding groove for the end of the limiting plate to be embedded is provided on the plate surface of the limiting piston facing the limiting plate. One end of the second elastic member in the direction of its elastic force is connected to the inner wall of the power flow channel, and the other end of the second elastic member in the direction of its elastic force is connected to the surface of the power piston. The second elastic member has an elastic force to drive the power piston to slide towards the sliding cavity. The end of the power piston protrudes from the inner wall of the sliding cavity, and the limiting piston slides towards the direction away from the limiting cavity. The end surface of the limiting piston abuts against the plate surface of the limiting plate, and there is a tendency for the plate surface of the limiting plate to be flush with the inner wall of the sliding cavity. When the positioning box is embedded in the sliding cavity, the end surface of the positioning box abuts against the end surface of the power piston and drives the power piston close to the power flow channel, pushing the limiting piston to slide towards the limiting cavity. The embedding groove faces the end of the limiting plate. The elastic force of the first elastic member drives the end of the limiting plate to be embedded in the embedding groove, and the plate surface of the limiting plate and the inner wall of the sliding cavity clamp both sides of the positioning box to form a limit.

[0018] By adopting the above technical solution, the elastic force of the second elastic member drives the power piston to slide towards the sliding cavity. The end of the power piston protrudes from the inner wall of the sliding cavity, and the air pressure in the power flow channel decreases. The external atmospheric pressure drives the limiting piston to slide along the power flow channel towards the direction away from the limiting cavity. The end surface of the limiting piston abuts against the plate surface of the limiting plate, and the plate surface of the limiting plate is flush with the inner wall of the sliding cavity. The positioning box is embedded in the sliding cavity. The end surface of the positioning box abuts against the end surface of the power piston and drives the power piston to slide towards the direction away from the sliding cavity. The end surface of the power piston is flush with the inner wall of the sliding cavity. At the same time, the air pressure in the power flow channel increases, and the air in the power flow channel squeezes the limiting piston and drives the limiting piston to slide towards the limiting cavity. The embedding groove faces the end of the limiting plate, and the limiting effect of the limiting piston on the limiting plate disappears. The elastic force of the first elastic member drives the end of the limiting plate to be embedded in the embedding groove, and the plate surface of the limiting plate and the inner wall of the limiting cavity clamp both sides of the positioning box to form a limit, making the positioning box not easily shift on the inner wall of the sliding cavity, thereby improving the limiting stability of the positioning box in the sliding cavity.

[0019] Optionally, a water outlet flow channel for the pipeline to be embedded is formed on the surface of the filtering seat facing one water inlet end of the pump body. The water outlet flow channel is communicated with the filtering cavity. The filtering seat is connected with an opening and closing assembly. The opening and closing assembly includes an opening and closing piston, a third elastic member, a plurality of floats, a plurality of opening and closing plates and a plurality of connecting ropes. An opening and closing flow channel for the opening and closing piston to slide is formed on the surface of the filtering seat. The opening and closing flow channel is communicated with the water outlet flow channel. An opening and closing cavity is formed on the surface of the opening and closing piston facing the water outlet flow channel. The opening and closing cavity penetrates through the surface of the opening and closing piston. One end of the third elastic member in the direction of the elastic force is connected to the inner wall of the opening and closing cavity, and the other end of the third elastic member in the direction of the elastic force is connected to the surface of the opening and closing piston. The third elastic member has an elastic force to drive the opening and closing piston to slide towards the direction close to the water outlet flow channel. The opening and closing cavity is in a trend of being communicated with the water outlet flow channel. The floats correspond to the positioning boxes one by one. A sliding groove for the float to slide is formed on the inner wall of each positioning box. The sliding direction of the float is parallel to the sliding direction of the opening and closing piston. The opening and closing plates correspond to the sliding cavities one by one. An opening and closing groove for the opening and closing plate to slide is formed on the inner wall of each sliding cavity close to the opening and closing flow channel. The opening and closing groove is communicated with the opening and closing flow channel. The connecting ropes correspond to the opening and closing plates one by one. One end of the connecting rope is connected to the end face of the opening and closing plate facing the opening and closing flow channel, and the other end of the connecting rope is connected to the surface of the opening and closing piston. The connecting rope is in a taut state. The end of the opening and closing plate away from the connecting rope faces the float.

[0020] By adopting the above technical solution, the elastic force of the third elastic member drives the opening and closing piston to slide towards the direction close to the water outlet flow channel. The opening and closing cavity is communicated with the water outlet flow channel. The water in the filtering cavity sequentially enters the water inlet end of the pump body through the water outlet flow channel, the opening and closing cavity and the pipeline, and the water resource filtered by multiple stages in the filtering cavity is discharged. When the filter plate is blocked by impurities in the water and needs to be replaced, the liquid level in the positioning box continuously rises. The float slides along the inner wall of the sliding groove towards the direction close to the opening and closing plate under the buoyancy of the water. The end face of the float abuts against the plate surface of the opening and closing plate and drives the opening and closing plate to slide along the inner wall of the opening and closing groove towards the direction away from the positioning box. The connecting rope receives the power of the opening and closing plate and drives the opening and closing piston to overcome the elastic force of the third elastic member and slide along the inner wall of the opening and closing flow channel towards the direction away from the water outlet flow channel. The communication effect between the opening and closing cavity and the water outlet flow channel disappears. The end face of the opening and closing piston abuts tightly against the inner wall of the opening and closing flow channel and closes the water outlet flow channel, realizing the directional discharge of the water in the filtering cavity.

[0021] Optionally, the opening and closing assembly further includes a contact switch. The contact switch is connected to the inner wall of the opening and closing flow channel close to the water outlet flow channel. The contact switch is electrically connected to the first pump body. When the opening and closing cavity is communicated with the water outlet flow channel, the contact switch abuts against the surface of the opening and closing piston and is turned on, and the first pump body is powered on and operates.

[0022] By adopting the above technical solution, the three elastic forces of the elastic part drive the opening and closing piston to slide along the inner wall of the opening and closing flow channel toward the water outlet flow channel, and the opening and closing cavity is connected to the water outlet flow channel. At the same time, the contact switch abuts the surface of the opening and closing piston and is turned on, and the pump body is energized and runs; when the float abuts the surface of the opening and closing plate and drives the opening and closing plate to slide in the direction away from the positioning box, the connecting rope receives the power of the opening and closing plate and drives the opening and closing piston to slide along the inner wall of the opening and closing flow channel toward the direction away from the water outlet flow channel, the abutment effect between the contact switch and the opening and closing piston disappears, the pump body is powered off and stops running, realizing directional starting of the pump body, reducing energy loss, and thus embodying the concept of energy saving.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The arrangement of the sliding seat, clamping seat and clamping assembly enables the nozzle to automatically impact clean each surface of the part to be cleaned. There is no need for workers to remove the part from the clamping assembly and adjust the orientation, which reduces the cleaning steps for the part, shortens the processing cycle of the part, and thus reduces the processing cost of the part. 2. The setting of the clamping plate, rotating cylinder and positioning piece, the clamping plate surface and the inner wall of the positioning groove clamp the two sides of the part to form a limit, making it difficult for the part to fall out of the positioning groove, improving the stability of the part in the positioning space, and thus ensuring the stability of the water column impacting the surface of the part for cleaning; 3. The water tank, pump body 1, pump body 2 and filter are set up. Pump body 2 returns the water filtered in the filter to the water tank through a pipeline, realizing the recycling of water resources, reducing resource consumption, and thus embodying the concept of environmental protection.

Two door bodies 5 are slidably connected to the inner wall of the cleaning chamber 11 at intervals. The sliding direction of the door bodies 5 is parallel to the length direction of the base body 1. When the two door bodies 5 slide towards each other, the end faces of the two door bodies 5 facing each other abut and close the cleaning chamber 11, so that the water flow in the cleaning chamber 11 is not easily splashed out of the cleaning chamber 11, realizing the stable impact of the water flow on the surface of the parts in the cleaning chamber 11; the clamping device 2, the cleaning device 3 and the demisting assembly 4 are connected to the surface of the base body 1 at intervals. The clamping device 2 can clamp multiple parts and drive the parts to slide in the cleaning chamber 11. The cleaning device 3 can drive the water column to sequentially impact multiple parts on the clamping device 2, realizing the automatic cleaning of multiple parts, improving the cleaning efficiency of the parts, shortening the processing cycle of the parts, and thus reducing the processing cost of the parts. The demisting assembly 4 can suck the oil mist in the cleaning chamber 11, enabling the staff to observe the cleaning state of the parts in real time through the viewing mirror on the door body 5, further improving the cleaning efficiency of the parts.

[0033] Refer to Figure 1 andFigure 2 The clamping device 2 includes a sliding seat 21, a clamping seat 22 and a clamping assembly 23. The sliding seat 21 is slidably connected to the inner wall of the cleaning chamber 11. The sliding direction of the sliding seat 21 is parallel to the length direction of the seat body 1.

When the parts are embedded in the positioning spaces 2332 and the part ends are embedded in the positioning grooves 2333 one by one, the inner walls of the positioning grooves 2333 abut the surface of the parts to form a limit, so that the parts are not easily offset on the surface of the clamping seat 22, thereby improving the limit stability of the parts on the clamping seat 22.

When the parts are embedded in the positioning space 2332 and the ends of the parts are embedded in the positioning grooves 2333 one by one, the rotation of the piston rod of the rotating cylinder 232 drives the two ends of the clamping plate 231 in the length direction to rotate toward the direction close to the positioning space 2332. The plate surface of the clamping plate 231 and the inner wall of the positioning groove 2333 are pressed against the two sides of the parts to form a limit, so that the parts are not easy to leave the positioning space 2332, thereby improving the limit stability of the parts on the positioning parts 233.

The water outlet channel 3345 communicates with the filter cavity 3344. The water inlet end of the first pump body 332 is embedded into the water outlet channel 3345 through the pipeline and communicates with the filter cavity 3344. A plurality of sliding cavities 3346 for the positioning boxes 3343 to slide are spaced apart on the inner wall of the filter cavity 3344. The arrangement direction of the positioning boxes 3343 is parallel to the width direction of the seat body 1, and the sliding cavities 3346 penetrate the surface of the filter base 3341 in the direction away from the seat body 1. The arrangement direction of the sliding cavities 3346 is parallel to the height direction of the seat body 1. The filter plates 3342 correspond to the positioning boxes 3343 one by one and are embedded into the inner cavities of the positioning boxes 3343. The outer peripheral surfaces of the filter plates 3342 abut against the inner walls of the positioning boxes 3343 to form a limit. The filter plates 3342 can filter the water in the positioning boxes 3343. A plurality of sieve holes 3357 are spaced apart on the bottom wall of the positioning box 3343. The axis of the sieve holes 3357 is parallel to the height direction of the seat body 1. The sieve holes 3357 penetrate the bottom wall of the positioning box 3343 along their own axes.

[0038] Referring to Figure 3 and Figure 4 , when the water in the drainage channel 13 enters the positioning box 3343, the filter plate 3342 filters the water and then enters the inner cavity of the adjacent positioning box 3343 through the sieve holes 3357. The filter plates 3342 in the adjacent positioning boxes 3343 filter the water again. When the water in the filter cavity 3344 accumulates on the bottom wall of the filter cavity 3344 after being multi-stage filtered by a plurality of filter plates 3342 in sequence, the first pump body 332 operates and drives the water in the filter cavity 3344 to enter the inner cavity of the water tank 331 through the water outlet channel 3345 and the pipeline, realizing the recycling of water resources, making the water not easily carry impurities into the first pump body 332 to interfere with the operation of the first pump body 332, thereby prolonging the service life of the high-pressure cleaning equipment.

[0039] Referring to Figure 5 and Figure 6, the limiting component 6 can limit the positioning box 3343 to slide on the inner wall of the sliding cavity 3346. The number of the limiting components 6 can be one or two. In the embodiment of the present application, the number of the limiting components 6 is two, and the two limiting components 6 correspond to the two ends of the positioning box 3343 in the length direction one by one. The limiting component 6 includes a limiting plate 61, a first elastic member 62, a limiting piston 63, a power piston 64 and a second elastic member 65. The first elastic member 62 and the second elastic member 65 can be compression springs or tension springs. In the embodiment of the present application, both the first elastic member 62 and the second elastic member 65 are compression springs and have a certain deformation ability. The materials of the limiting piston 63 and the power piston 64 can be rubber or silica gel. In the embodiment of the present application, the materials of both the limiting piston 63 and the power piston 64 are rubber and have a certain deformation ability. A limiting cavity 3358 for the limiting plate 61 to slide is formed on the surface of the filter seat 3341. The sliding direction of the limiting plate 61 is parallel to the length direction of the seat body 1. The limiting cavity 3358 communicates with a plurality of sliding cavities 3346. One end of the first elastic member 62 in the direction of the elastic force is connected to the inner wall of the limiting cavity 3358, and the other end of the first elastic member 62 in the direction of the elastic force is connected to the plate surface of the limiting plate 61. The first elastic member 62 has an elastic force to drive the limiting plate 61 to slide towards the sliding cavity 3346, and a tendency of the plate surface of the limiting plate 61 and the inner wall of the sliding cavity 3346 to clamp both sides of the positioning box 3343 to form a limit.

[0040] Referring to Figure 5 and Figure 6 , a power flow channel 3359 for the power piston 64 to slide is formed on the inner wall of the sliding cavity 3346. The sliding direction of the power piston 64 is parallel to the sliding direction of the positioning box 3343. The power flow channel 3359 communicates with the limiting cavity 3358. The limiting piston 63 is slidably connected to the inner wall of the power flow channel 3359 close to the limiting cavity 3358. The sliding direction of the power piston 64 is parallel to the sliding direction of the limiting piston 63. An embedding groove 631 for the end of the limiting plate 61 to be embedded is formed on the end surface of the power piston 64 facing the limiting plate 61. One end of the second elastic member 65 in the direction of the elastic force is connected to the inner wall of the power flow channel 3359, and the other end of the second elastic member 65 in the direction of the elastic force is connected to the surface of the power piston 64. The second elastic member 65 has an elastic force to drive the power piston 64 to slide towards the sliding cavity 3346. The end of the power piston 64 protrudes from the inner wall of the sliding cavity 3346, driving the limiting piston 63 to slide away from the limiting cavity 3358. The end surface of the limiting piston 63 abuts against the plate surface of the limiting plate 61, and there is a tendency that the plate surface of the limiting plate 61 is flush with the inner wall of the sliding cavity 3346.

[0041] Referring to Figure 5 and Figure 6When the positioning box 3343 is embedded in the sliding cavity 3346 and the end face of the positioning box 3343 abuts against the end of the power piston 64 protruding from the sliding cavity 3346, the positioning box 3343 drives the power piston 64 to slide away from the sliding cavity 3346 against the elastic force of the second elastic member 65. The end face of the power piston 64 is flush with the inner wall of the sliding cavity 3346, and the end face of the positioning box 3343 is flush with the inner wall of the limiting cavity 3358. At the same time, the air pressure in the power flow channel 3359 increases, pushing the limiting piston 63 to slide towards the limiting cavity 3358. The embedding groove 631 faces the plate surface of the limiting plate 61, and the limiting effect of the limiting piston 63 on the limiting plate 61 disappears. The elastic force of the first elastic member 62 drives the limiting plate 61 to slide along the inner wall of the limiting cavity 3358 towards the sliding cavity 3346. The end of the limiting plate 61 is embedded in the embedding groove 631 to form a limit. At the same time, the plate surface of the limiting plate 61 and the inner wall of the sliding cavity 3346 clamp both sides of the positioning box 3343 to form a limit, making it difficult for the positioning box 3343 to shift on the inner wall of the sliding cavity 3346, thereby improving the limiting stability of the positioning box 3343 in the sliding cavity 3346.

[0042] Referring to Figure 3 and Figure 4 As shown in

[0043] Referring to Figure 3 and Figure 4, the third elastic member 72 can be a compression spring or a tension spring. In the embodiment of the present application, the third elastic member 72 is a compression spring, which has a certain deformation ability. One end of the third elastic member 72 in the direction of its elastic force is connected to the inner wall of the opening and closing flow channel 8, and the other end of the third elastic member 72 in the direction of its elastic force is connected to the surface of the opening and closing piston 71. The third elastic member 72 has an elastic force to drive the opening and closing piston 71 to slide in the direction close to the water outlet flow channel 3345, and there is a tendency for the opening and closing cavity 711 to communicate with the water outlet flow channel 3345; the float 74 corresponds to the positioning box 3343 one by one. The positioning box 3343 is provided with a sliding groove 10 for the float 74 to slide on the inner wall close to the opening and closing flow channel 8. The sliding direction of the float 74 is parallel to the sliding direction of the opening and closing piston 71. The opening and closing plate 75 corresponds to the sliding cavity 3346 one by one. The inner walls of the sliding cavities 3346 close to the opening and closing flow channel 8 are all provided with opening and closing grooves 14 for the opening and closing plate 75 to slide. The opening and closing grooves 14 communicate with the opening and closing flow channel 8, and the sliding direction of the opening and closing plate 75 is parallel to the sliding direction of the float 74. The connecting rope 76 corresponds to the opening and closing plate 75 one by one. One end of the connecting rope 76 is fixed to the end face of the opening and closing plate 75 facing the opening and closing flow channel 8, and the other end of the connecting rope 76 is fixed to the end face of the opening and closing piston 71. The connecting rope 76 between the opening and closing plate 75 and the opening and closing piston 71 is in a taut state, and the end of the opening and closing plate 75 far from the connecting rope 76 faces the surface of the float 74.

[0044] Referring to Figure 3 and Figure 4 , the contact switch 73 is embedded in the inner wall of the opening and closing flow channel 8 close to the water outlet flow channel 3345. The contact switch 73 is electrically connected to the first pump body 332. When the elastic force of the third elastic member 72 drives the opening and closing piston 71 to slide in the direction close to the water outlet flow channel 3345, the opening and closing cavity 711 communicates with the water outlet flow channel 3345. The contact switch 73 abuts against the opening and closing piston 71 and is turned on. The first pump body 332 is powered on and operates, driving the water that has completed multi-stage filtration in the filtration cavity 3344 to pass through the water outlet flow channel 3345 and the opening and closing cavity 711 in sequence and enter the water inlet end of the first pump body 332 through the pipeline; when the filter holes of the filter plate 3342 are blocked by impurities in the water and need to be replaced, the liquid level in the positioning box 3343 rises. The float 74 slides along the inner wall of the sliding groove 10 in the direction close to the opening and closing plate 75 under the buoyancy of the water. The float 74 abuts against the plate surface of the opening and closing plate 75 and drives the opening and closing plate 75 to slide in the direction away from the positioning box 3343. The connecting rope 76 receives the power of the opening and closing plate 75 and drives the opening and closing piston 71 to slide along the inner wall of the opening and closing flow channel 8 in the direction away from the water outlet flow channel 3345. The communication effect between the opening and closing cavity 711 and the water outlet flow channel 3345 disappears. The end face of the opening and closing piston 71 abuts tightly against the inner wall of the opening and closing flow channel 8 and closes the water outlet flow channel 3345. At the same time, the abutting effect between the contact switch 73 and the opening and closing piston 71 disappears. The first pump body 332 is powered off and stops operating, realizing the directional start of the first pump body 332, reducing energy consumption, and thus reflecting the concept of energy saving.

[0045] Referring to Figure 1, the demisting assembly 4 includes an oil mist purifier 41 and a demisting pipeline 42. The bottom of the oil mist purifier 41 abuts against the ground to form a support. One end of the demisting pipeline 42 is fixed on the seat body 1 and communicates with the cleaning chamber 11. The other end of the demisting pipeline 42 is connected to the driving end of the oil mist purifier 41. The oil mist purifier 41 sucks the oil mist in the cleaning chamber 11 through the demisting pipeline 42, enabling the staff to clearly observe the cleaning state of the parts through the viewing mirror on the door body 5, thereby improving the cleaning efficiency of the parts.

At the same time, the rotary cylinder 232 drives the two ends of the clamping plate 231 to rotate towards the direction close to the positioning space 2332 one by one. The clamping plate 231 and the inner wall of the positioning groove 2333 clamp the two ends of the part to form a limit, realizing the fixation of multiple parts on the clamping seat 22. The water outlet end of the nozzle 32 faces the surface of the part to be cleaned. The high-pressure water column sprays on the surface of the part to be cleaned through the water outlet end of the nozzle 32, and the impurities adhered to the surface of the part during turning processing are carried by the water flow through the drain holes 222 and the drain cavity 221 into the bottom wall of the cleaning chamber 11 and enter the filter 334 through the drain channel 13, realizing the efficient cleaning of the surface of the part to be cleaned; at the same time, the sliding seat 21 is driven to slide on the inner wall of the cleaning chamber 11, so that other surfaces of the part to be cleaned are close to the water outlet end of the nozzle 32, and the clamping seat 22 slides on the surface of the sliding seat 21, so that other surfaces of the part to be cleaned face the water outlet end of the nozzle 32, realizing the automatic impact cleaning of the nozzle 32 on each surface of the part to be cleaned. There is no need for the staff to take the part off the clamping assembly 23 and adjust the orientation, reducing the cleaning steps of the part and shortening the processing cycle of the part, thereby reducing the processing cost of the part; at the same time, the adjusting seat 31 is slidably connected to the inner wall of the cleaning chamber 11 to adjust the distance between the water outlet end of the nozzle 32 and the surface of the part to be processed, so as to ensure that the water flow impacts the surface of the part at an appropriate angle and speed, thereby improving the cleaning efficiency of the surface of the part.
