Description

Technical Field

[0001] The utility model relates to the technical field of water washing equipment, in particular to water washing equipment for spraying treatment of aviation parts. Background Art

[0002] Aircraft parts refer to the components and parts that make up an aircraft or other aircraft, and they play a key role in aviation engineering. These parts include various fuselages, engines, landing gear, electronic systems, fuel systems, hydraulic systems and other accessories. There are many types of aircraft parts, including wings, tails, fuselages, engines, landing gear, flight control surfaces, fuel tanks, communication and navigation systems, seats, flaps, rudders, propellers, tires, brake systems, etc. The spraying of aircraft parts is a key process. It not only affects the appearance of the parts, but also plays an important role in their performance, protection and identification. Spraying can protect the surface of the parts from corrosion, oxidation, ultraviolet radiation and chemical substances.

[0003] Aviation parts need to be cleaned before spraying. Cleaning the surface of parts can improve the quality and performance of the coating. Currently, most aviation parts are cleaned manually using hot water high-pressure cleaners. This method can effectively clean propellers, fuel tanks, etc., but it is difficult to completely remove tiny particles and grease from precision parts such as aircraft engine impellers, hubs, bearings, etc., and manual cleaning has a low cleaning efficiency. Utility Model Content

[0004] The utility model aims to provide a water washing device for spraying treatment of aviation parts to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A water washing device for spraying of aviation parts, comprising a lifting mechanism, wherein a water washing mechanism is arranged at the bottom of the lifting mechanism;

[0007] The water washing mechanism includes a cleaning box, two hydraulic cylinders are symmetrically fixedly connected to the bottom of the cleaning box, ultrasonic generators are fixedly arranged on the opposite inner walls of the cleaning box, a water inlet pipe connected to the interior is fixedly connected to the top of one side wall of the cleaning box, a water outlet pipe connected to the interior is fixedly connected to the bottom of the other side wall of the cleaning box, control valves are fixedly arranged on the water inlet pipe and the water outlet pipe, and a filter plate is arranged inside the cleaning box.

[0008] Furthermore, four sliding rods are symmetrically fixedly connected to the bottom of the filter plate about its vertical center plane, and the outsides of the four sliding rods are slidably sleeved with connecting plates fixedly connected to the inner wall of the cleaning box, and the outsides of the sliding rods are sleeved with return springs fixedly connected to the filter plate.

[0009] Furthermore, two eccentric blocks that are in conflict with the bottom of the filter plate are symmetrically arranged at the bottom, a rotating column is fixedly connected between the two eccentric blocks, the rotating column is rotatably connected to the cleaning box, and the end of the rotating column is fixedly connected to the output end of the servo motor.

[0010] Furthermore, the lifting mechanism includes a protective cover, a base plate is fixedly connected to the bottom of the protective cover, two rotating shafts are rotatably connected inside the protective cover, sprockets are fixedly sleeved on the outer walls of the two rotating shafts, a chain is meshingly sleeved between the two sprockets, one end of the rotating shaft is fixedly connected to the output end of the driving motor, a plurality of connecting seats are fixedly connected to the chain at equal distances, a sliding groove is provided in the connecting seat, two moving rods are symmetrically slidably sleeved in the sliding groove, the bottom ends of the two moving rods are fixedly connected to clamp rings, protective plates are provided on both sides of the chain, and positioning columns are fixedly connected to the side walls of the protective plates.

[0011] Furthermore, sliding columns slidably connected to the connecting seats are fixedly connected to the side walls of the two moving rods, and the ends of the sliding columns are fixedly connected to the positioning seats. The positioning seats are rotatably connected to rollers, and the interior of the protective cover is symmetrically fixedly connected to two sliding rail plates, and the rollers are slidably abutted against the inner walls of the sliding rail plates, and the ends of the two sliding rail plates are fixedly connected to rail folding plates.

[0012] Furthermore, a tension spring fixedly connected to the connecting seat is sleeved on the outside of the sliding column.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The lifting mechanism can continuously transport aviation parts to the top of the cleaning box, and the hydraulic cylinder can lift the cleaning box until the aviation parts are completely immersed in the clean water inside the box. Then the ultrasonic generator emits ultrasonic waves, and the cavitation, acceleration and straight flow of ultrasonic waves in the liquid directly or indirectly act on the liquid and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the cleaning purpose, thereby facilitating the removal of oil stains and tiny particles from precision aviation parts. Compared with the current high-pressure washing method, this will not cause damage to the surface of the parts.

[0015] 2. During the ultrasonic cleaning process, the servo motor can drive the rotating column and the two eccentric blocks to rotate. Since four reset springs are connected to the bottom of the filter plate to quickly reset it, the eccentric block can push the filter plate to vibrate up and down, so that the stubborn stains and particles adhering to the surface of the parts on the filter plate can be completely removed by ultrasonic cleaning, thereby improving the completeness and thoroughness of the cleaning of the parts.

[0016] 3. The sprocket can be driven to rotate by the output end of the driving motor, and the chain can be driven to roll by the two sprockets, thereby driving multiple connecting seats to roll along the chain at the same time. When the connecting seat drives the roller and the track folding plate to slide and contact each other, the two track folding plates can contact the roller and gradually shrink to between the two slide rails, thereby driving the sliding column to slide in the connecting seat, thereby driving the clamping rings at the ends of the sliding column to merge together, and the aviation parts can be suspended and driven to move together through the two merged clamping rings. By simultaneously lifting multiple aviation parts and moving them to the water washing mechanism, and then batch cleaning them through the water washing mechanism, the cleaning efficiency of the aviation parts is improved. When the roller and the slide rail plate are separated, the tension spring pulls the sliding column to reset, so that the two clamping rings will separate and release the parts.

[0025] The water washing mechanism 200 includes a cleaning box 201, two hydraulic cylinders 205 are symmetrically fixedly connected to the bottom of the cleaning box 201, ultrasonic generators 202 are fixedly arranged on the opposite inner walls of the cleaning box 201, a water inlet pipe 203 connected to the interior is fixedly connected to the top of one side wall of the cleaning box 201, and a water outlet pipe 204 connected to the interior is fixedly connected to the bottom of the other side wall of the cleaning box 201, control valves are fixedly arranged on the water inlet pipe 203 and the water outlet pipe 204, and a filter plate 206 is arranged inside the cleaning box 201.

[0026] Specifically, the lifting mechanism 100 can continuously transport the aviation parts to the top of the cleaning box 201, and the hydraulic cylinder 205 can lift the cleaning box 201 so that the aviation parts are completely immersed in the clean water inside the cleaning box 201, and then the ultrasonic generator 202 emits ultrasonic waves, and then the cavitation effect, acceleration effect and straight flow effect of the ultrasonic waves in the liquid directly or indirectly act on the liquid and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the cleaning purpose, thereby facilitating the removal of oil stains and tiny particles from precision aviation parts. Compared with the current high-pressure washing method, this will not cause damage to the surface of the parts.

[0027] Embodiment 1

[0028] like Figure 5As shown, in this embodiment, the bottom of the filter plate 206 is symmetrically fixedly connected with four slide rods 207 about its vertical center plane, the outside of the four slide rods 207 are slidably sleeved with a connecting plate 208 fixedly connected to the inner wall of the cleaning box 201, and the outside of the slide rods 207 is sleeved with a return spring 209 fixedly connected to the filter plate 206; the bottom of the filter plate 206 is symmetrically provided with two eccentric blocks 210 that are in conflict with its bottom, and a rotating column 211 is fixedly connected between the two eccentric blocks 210, the rotating column 211 is rotatably connected to the cleaning box 201, and the end of the rotating column 211 is fixedly connected to the output end of the servo motor 212.

[0029] In this embodiment, during the ultrasonic cleaning process, the servo motor 212 can drive the rotating column 211 and the two eccentric blocks 210 to rotate.

[0030] Embodiment 2

[0031] like Figure 2-3 As shown, in this embodiment, the lifting mechanism 100 includes a protective cover 101, a base plate 102 is fixedly connected to the bottom of the protective cover 101, two rotating shafts 103 are rotatably connected inside the protective cover 101, sprockets 104 are fixedly sleeved on the outer walls of the two rotating shafts 103, a chain 105 is meshed and sleeved between the two sprockets 104, an end of one rotating shaft 103 is connected to the output end of the driving motor 106, a plurality of connecting seats 111 are fixedly connected to the chain 105 at equal distances, a slide groove 112 is provided in the connecting seat 111, two moving rods 113 are symmetrically slidably sleeved in the slide groove 112, and the bottom ends of the two moving rods 113 are fixedly connected to clamp rings 114.
