[0004] When degreasing a gear workpiece, an existing degreasing device usually uses a nozzle flushing method to flush the gear. Due to the different shapes of the gears and the fixed position of the nozzle, the pressure on the gear tooth block and the gear tooth gap during flushing is different, and the tooth gap cannot be thoroughly flushed. For example, the above-mentioned referenced prior art uses multiple groups of cleaning nozzles to flush the gear parts at the same time for degreasing.

DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0051] Example 1: Reference Figure 1-Figure 2 , an air-water dual-purpose gear workpiece degreasing device, comprising a plurality of gear parts 14 to be cleaned placed in a cleaning tank 1;

[0052] The degreasing device also includes:

[0053] The hanging unit is arranged in the cleaning tank 1, and is used to realize the hanging positioning of the gear parts 14 and the position adjustment during cleaning, so that multiple gear parts 14 can be quickly installed, positioned and disassembled, and at the same time, the angular position of the gear parts 14 can be assisted to be adjusted during flushing, so that the gear parts 14 can be synchronously degreased and flushed on the outer surface, gears and tooth gaps, and inner rings, and the flushing and degreasing of the gear parts 14 is more comprehensive;

[0054] The degreasing and cleaning unit is arranged in the cleaning tank 1, and is used to realize the degreasing, cleaning, dehydration and drying of the gear parts 14. During the flushing and degreasing, the gear parts 14 can be fully flushed, and the flushing stroke can be flexibly adjusted according to the required flushing position to improve the flushing effect and avoid flushing dead corners. After flushing, the gear parts 14 can be dehydrated and dried, thereby further improving the degreasing and cleaning effect of the gear parts 14.

[0055] Example 2: Reference Figure 2-Figure 8 The technical solution of this embodiment is different from that of the first embodiment in that the hanging unit includes a positioning component and a positioning component, wherein the positioning component is used to realize the positioning of the gear part 14, and the positioning component is used to adjust the position of the gear part 14 to realize comprehensive degreasing and cleaning;

[0056] The positioning assembly includes a clamping plate 17 clamped and fixed on the positioning clamping slot 16, and a hanging frame 9 is fixedly installed on the clamping plate 17, a middle rod 19 is rotatably installed at the lower part of the clamping plate 17, and a plurality of clamping mechanisms for positioning the gear member 14 are installed on the middle rod 19;

[0057] The clamping mechanism includes a positioning collar 23 fixedly mounted on the middle rod 19, a plurality of contraction springs 21 are fixedly mounted on the positioning collar 23, and an elastic clamping frame 20 is fixedly mounted on each two contraction springs 21 in the vertical position, and the gear member 14 is clamped and positioned between the plurality of elastic clamping frames 20;

[0058] When washing the gear member 14, first insert the gear member 14 from the lower part of the middle rod 19 into the middle rod 19, and move the gear member 14 upward on the middle rod 19. When the gear member 14 moves to the positioning ring 23, the multiple elastic snap-fit ​​frames 20 are pressed to compress the multiple contraction springs 21, so that the inner ring of the gear member 14 is snapped between the multiple elastic snap-fit ​​frames 20, forming a position as shown in the appendix of the manual. Figure 7 In the state shown, the positioning of the gear member 14 is completed, and the above steps are repeated in sequence to complete the engagement and positioning of multiple gear members 14, so that they will not shake during flushing, thereby improving the flushing effect.

[0059] In a further embodiment, the positioning assembly includes two hydraulic push rods 3 fixedly mounted on the cleaning tank 1, and a squeeze plate 13 is fixedly mounted on the driving ends of the two hydraulic push rods 3, and a positioning slot 16 for positioning is provided on the squeeze plate 13;

[0060] After the multiple gear members 14 are positioned and the upper structure of the middle rod 19 is installed, the hanging frame 9 can be held to drive the middle rod 19 to move as a whole through the snap plate 17, so that the middle rod 19 is inserted into the positioning slot 16 on the extrusion plate 13, and the snap plate 17 is pressed down to snap and position it into the positioning slot 16, completing the positioning of the snap plate 17 and the positioning slot 16. At this time, when the extrusion plate 13 moves, it will drive the snap plate 17 to move as a whole through the positioning slot 16, thereby driving the multiple gear members 14 to move as a whole;

[0061] Electromagnets can be set on the positioning slot 16 and the locking plate 17. When the positioning slot 16 and the locking plate 17 are locked and positioned, the two electromagnets are started to make the positioning slot 16 and the locking plate 17 tightly adsorbed, which can further improve the fixing effect between the locking plate 17 and the positioning slot 16 and improve the overall connection stability between the extrusion plate 13 and the locking plate 17.

[0062] Example 3: Reference Figure 2-Figure 4 as well as Figure 9-14The difference between this embodiment and the second embodiment is that the degreasing cleaning unit includes a cleaning component, a dehydration component and a liquid return component, wherein the cleaning component is used for both air and water, and is used to realize water replenishment cleaning and air replenishment drying of the gear part 14, the dehydration component is used to realize dehydration of the gear part 14 after cleaning, and the liquid return component is used to recycle and clean the clean water in the cleaning component, and replenish the clean water after cleaning into the cleaning component to realize backwashing of the gear part 14;

[0063] The cleaning assembly includes a conductive ring 2 fixedly mounted on the outside of the cleaning tank 1, a high-pressure air pipe 6 and a high-pressure water pipe 7 are fixedly connected to the conductive ring 2, and a control valve is provided on the high-pressure air pipe 6 and the high-pressure water pipe 7, the high-pressure air pipe 6 is used to conduct compressed air, and the high-pressure water pipe 7 is used to conduct high-pressure cleaning water;

[0064] When the gear member 14 is positioned, the control valve on the high-pressure water pipe 7 can be opened to pour the external high-pressure degreasing cleaning water into the high-pressure water pipe 7. The cleaning water in the high-pressure water pipe 7 will be poured into the conductive ring 2 to complete the injection of high-pressure cleaning water. At this time, the high-pressure air pipe 6 is in a closed state and no compressed air is injected.

[0065] Two conduction tubes 28 are fixedly installed on the conduction ring 2 and the cleaning tank 1, and each conduction tube 28 is fixedly connected to a conduction box 27, and a plurality of flushing mechanisms are installed on the conduction box 27, and a flushing pipe 30 is fixedly connected to the conduction box 27, and a driving impeller 18 matched with the flushing pipe 30 is fixedly installed on the middle rod 19;

[0066] The clean water in the conduction ring 2 will be injected into the conduction box 27 through the conduction pipe 28, and will be flushed out through the flushing pipe 30. The high-pressure clean water flushed out through the flushing pipe 30 will hit the driving impeller 18, that is, the driving impeller 18 will be promoted to rotate under the action of the impact force, and then the center rod 19 will be driven to rotate slowly. When the center rod 19 rotates, it will drive the multiple gear parts 14 thereon to rotate together, and the gear part 14 can be automatically driven to rotate during flushing, and then the flushing position of the gear part 14 can be adjusted, so that the gear part 14 can be fully flushed and cleaned to avoid flushing dead corners.

[0067] In a further embodiment, the flushing mechanism includes a fixed pipe 29 fixedly connected to the conduction box 27, a conduction disk 33 fixedly connected to the fixed pipe 29 through an elastic telescopic tube 31, and a flushing nozzle 32 for flushing the side of the gear member 14 fixedly connected to the conduction disk 33, and two external flushing pipes 35 for flushing the upper and lower parts of the gear member 14 fixedly connected to the conduction disk 33;

[0068] The clean water in the conduction box 27 will be injected into the elastic telescopic tube 31 through the fixed tube 29, and then injected into the conduction disk 33 through the elastic telescopic tube 31, and finally flushed out through the flushing nozzle 32 and the two external flushing tubes 35. The clean water flushed out of the flushing nozzle 32 will directly act on the side of the gear part 14, so that the side of the gear part 14 can be flushed and degreased, and the clean water flushed out of the upper and lower external flushing tubes 35 will be flushed to the upper and lower surfaces of the gear part 14, and flushed into the inner ring of the gear part 14 through the gap between the gear part 14 and the center rod 19, so that the upper and lower surfaces and the inner ring of the gear part 14 can be flushed synchronously. Through the cooperation of the two external flushing tubes 35 and the flushing nozzle 32, the gear part 14 can be fully flushed and degreased without any flushing dead corners.

[0069] A plurality of high-pressure flushing pipes 34 are fixedly connected to the fixed pipe 29, and the plurality of high-pressure flushing pipes 34 are matched with the conducting disc 33. A high-pressure control valve is arranged on each high-pressure flushing pipe 34. A part of the flushing water in the fixed pipe 29 will be flushed out through the plurality of high-pressure flushing pipes 34 and impact on the conducting disc 33. During the actual flushing, the opening and closing and impact pressure of the plurality of high-pressure flushing pipes 34 can be flexibly adjusted according to the size of the gear part 14, the distance between the flushing nozzle 32 and the outer teeth and tooth gaps of the gear part 14, and the impact force of the plurality of high-pressure flushing pipes 34 impacting on the conducting disc 33 can be adjusted.

[0070] When the amount of high-pressure cleaning water that impacts the conducting plate 33 increases and the pressure increases, the conducting plate 33 will be subjected to a greater thrust, that is, it will move forward, thereby driving the flushing nozzle 32 to move forward, so that the flushing nozzle 32 is close to the gear member 14, and the stroke and pressure of the cleaning water flushed out of the flushing nozzle 32 are adjusted, thereby performing a more thorough and targeted flushing of the tooth blocks and tooth gaps of the gear member 14, and achieving a better flushing effect;

[0071] By adjusting the impact of multiple high-pressure flushing pipes 34, adjusting the force applied to the conduction disk 33 and thus adjusting its moving distance, the distance between the flushing nozzle 32 and the gear part 14 is automatically adjusted to achieve targeted flushing and degreasing, with better flushing effects and no flushing dead angles.

[0072] When in actual use, each set of cleaning components will perform independent degreasing and flushing on a single gear part 14 in a targeted manner, which has a better cleaning effect. When in actual use, according to the cleaning requirements, a single gear part 14 or multiple gear parts 14 can be adaptively selected for cleaning, which can not only achieve independent cleaning of a single gear part 14 and improve the cleaning effect, but also can clean multiple gear parts 14 simultaneously and improve the cleaning efficiency.

[0073] In a further embodiment, the dehydration assembly includes a separation plate 11 fixedly mounted in the cleaning tank 1, a lifting carrier plate 10 is slidably mounted in the cleaning tank 1, and the lifting carrier plate 10 is located on the upper part of the separation plate 11, the liquid return assembly includes a lower water tank 12 fixedly mounted on the separation plate 11 for draining sewage, and the lower water tank 12 is slidably connected to the lifting carrier plate 10, and the bottom of the cleaning tank 1 is fixedly connected to a sewage pipe 5 for draining sewage;

[0074] The wastewater generated during degreasing cleaning will fall onto the lifting carrier plate 10, and will fall to the lower part of the separation plate 11 (i.e., the bottom of the cleaning tank 1) through the lower water tank 12. After the initial flushing is completed, the drain pipe 5 can be opened to discharge the wastewater at the bottom of the cleaning tank 1.

[0075] The cleaning tank 1 is provided with a circulation mechanism, which includes an oil-water separation box 4 for separating oil and clean water, and the oil-water separation box 4 is connected to a sewage pipe 5, a water pump for absorbing and discharging clean water is provided in the oil-water separation box 4, and a return pipe 8 is fixedly connected to the water outlet of the water pump, and the upper end of the return pipe 8 is connected to a high-pressure water pipe 7, and a sewage box 36 for discharging oil is provided on the oil-water separation box 4;

[0076] The sewage discharged from the sewage pipe 5 will be injected into the oil-water separation box 4, and the oil-water separation box 4 will start to separate the sewage from oil and water, so that the clean water in the sewage is separated from the oil, and the separated oil is directly discharged through the sewage box 36, and then the water pump is started to pump the separated clean water into the return pipe 8, and then injected into the high-pressure water pipe 7 through the return pipe 8 to complete the return liquid replenishment of the clean water;

[0077] The return cleaning water entering the high-pressure water pipe 7 will be flushed again onto the gear parts 14 in the cleaning tank 1 through the cleaning component, so that the gear parts 14 can be flushed and cleaned again and the internal structure of the cleaning tank 1 can be backwashed, which can not only improve the utilization rate of cleaning water and avoid waste, but also further improve the flushing effect of the gear parts 14, thereby achieving thorough degreasing and cleaning of the gear parts 14.

[0078] The oil-water separation box 4 is a commonly used device for separating oil and water in existing equipment. It can automatically separate oil and clean water in sewage and independently store oil and clean water. This part is existing technology and will not be described in detail here.

[0079] After the secondary cleaning and flushing of the gear part 14 is completed, the high-pressure air pipe 6 can be opened and the high-pressure water pipe 7 can be closed. Compressed air is introduced into the high-pressure air pipe 6, and the compressed air is blown directly onto the gear part 14 through the conduction ring 2, the conduction tube 28, and the conduction box 27 through the flushing mechanism. The gear part 14 can be quickly blown and dried, and the clean water on the gear part 14 can be preliminarily blown off. Through the intermittent perfusion of the high-pressure air pipe 6 and the high-pressure water pipe 7, the same cleaning component can be used for both air and water, which can realize the flushing of the gear part 14 and the blowing and drying of the gear part 14. There is no need to set up a separate component for blowing, the utilization rate of the overall component is higher, and the overall cost is lower.

[0080] In a further embodiment, a pressure plate 15 is threadedly mounted on the lower portion of the center rod 19, an alcohol solution is filled between the separation plate 11 and the lifting and supporting plate 10, and the lifting and supporting plate 10 cooperates with the pressure plate 15;

[0081] After the positioning of the multiple gear members 14 is completed, the pressure plate 15 can be threadedly installed to the lower part of the middle rod 19 to complete the installation of the pressure plate 15, so as to avoid the pressure plate 15 blocking the installation of the gear members 14;

[0082] An upper liquid tank 24 is fixedly installed in the cleaning tank 1, and the upper liquid tank 24 is slidably connected to the lifting and lowering bearing plate 10. The lower part of the upper liquid tank 24 is fixedly connected to a liquid inlet box 26 for the alcohol solution to be added, and the lifting and lowering bearing plate 10 is fixedly connected to a liquid return pipe 22 for the alcohol solution to be returned.

[0083] After the gear member 14 is flushed, the two hydraulic push rods 3 can be started to drive the squeezing plate 13 to move downward. When the squeezing plate 13 moves downward, it will drive the middle rod 19 to move downward through the clamping plate 17. The middle rod 19 moves downward and drives the pressure plate 15 to move downward. The pressure plate 15 moves downward and squeezes the lifting and lowering bearing plate 10 below it, thereby pushing the lifting and lowering bearing plate 10 to move downward in the cleaning tank 1.

[0084] The downward movement of the lifting carrier plate 10 will squeeze the alcohol solution at the bottom thereof, and allow the alcohol solution to enter the upper liquid tank 24 through the liquid inlet box 26, and then flow upward through the upper liquid tank 24 and be poured into the upper part of the lifting carrier plate 10, that is, as the lifting carrier plate 10 gradually moves downward, the alcohol solution at the bottom thereof gradually decreases while the alcohol solution at the upper part gradually increases. When the lifting carrier plate 10 moves downward to the maximum position, the alcohol solution on the lifting carrier plate 10 will submerge the single or multiple gear parts 14 thereon, that is, the single or multiple gear parts 14 will be immersed in the alcohol solution. At this time, the alcohol solution will absorb the residual clean water on the gear parts 14, completing the further dehydration of the gear parts 14.

[0085] After a single or multiple gear parts 14 are soaked and dehydrated, the return liquid pipe 22 can be opened and the hydraulic push rod 3 can be contracted synchronously, so that the lifting support plate 10 automatically rises and rebounds under the action of the lifting spring 25 (the lifting spring 25 will be compressed when the lifting support plate 10 moves downward, and the lower water tank 12 is in a closed state). At this time, the alcohol solution on the lifting support plate 10 will return to its lower part through the return liquid pipe 22, completing the automatic separation of the alcohol solution and the gear parts 14.

[0086] After the immersion of a single or multiple gear parts 14 is completed, compressed air can be introduced again to blow the single or multiple gear parts 14 for a second time to blow away the residual alcohol solution on the gear parts 14, complete the thorough drying of the gear parts 14, and then complete the degreasing and cleaning process of the gear parts 14. After the degreasing and cleaning of the gear parts 14 is completed, the positioning of the clamping plate 17 can be released, and the gear parts 14 can be pulled out of the cleaning tank 1 through the hanging frame 9 to complete the disassembly of the gear parts 14.

[0087] The specific operation process of this degreasing device is:

[0088] Installation of the gear member 14: insert a single or multiple gear members 14 into the middle rod 19 from the lower part of the middle rod 19, and move the gear member 14 upward on the middle rod 19. When the gear member 14 moves to the positioning ring 23, press multiple elastic snap-fit ​​frames 20 to compress multiple contraction springs 21, so that the inner ring of the gear member 14 is snapped between the multiple elastic snap-fit ​​frames 20 to complete the positioning of the gear member 14. Repeat the above steps in sequence to complete the snap-fit ​​positioning of the gear member 14.

[0089] Degreasing and cleaning of the gear 14: Open the control valve on the high-pressure water pipe 7, and pour the external high-pressure degreasing cleaning water into the high-pressure water pipe 7. The cleaning water in the high-pressure water pipe 7 will be poured into the conductive ring 2, and the cleaning water in the conductive box 27 will be injected into the elastic telescopic tube 31 through the fixed tube 29, and then injected into the conductive disk 33 through the elastic telescopic tube 31, and finally flushed out through the flushing nozzle 32 and two external flushing pipes 35;

[0090] The clean water flushed out by the flushing nozzle 32 will directly act on the side of the gear part 14, so that the side of a single or multiple gear parts 14 can be flushed and degreased, and the clean water flushed out by the upper and lower external flushing pipes 35 will flush the upper and lower surfaces of the gear part 14, and flush into the inner ring of the gear part 14 through the gap between the gear part 14 and the middle rod 19, so that the upper and lower surfaces and the inner ring of the gear part 14 can be flushed synchronously. Through the cooperation of the two external flushing pipes 35 and the flushing nozzle 32, the comprehensive flushing and degreasing of a single or multiple gear parts 14 can be achieved without any flushing dead angles.

[0091] The sewage generated during degreasing cleaning will fall onto the lifting carrier plate 10, and will fall to the lower part of the cleaning tank 1 through the lower water tank 12. The sewage at the bottom of the cleaning tank 1 is discharged through the sewage pipe 5 and injected into the oil-water separation box 4. At this time, the oil-water separation box 4 will start to separate the sewage from oil and water, so that the clean water in the sewage is separated from the oil and dirt. The separated oil and dirt are directly discharged through the sewage box 36. Then the water pump is started to pump the separated clean water into the return pipe 8, and then injected into the high-pressure water pipe 7 through the return pipe 8 to complete the liquid return replenishment of the clean water.

[0092] The return cleaning water entering the high-pressure water pipe 7 will be flushed to the gear part 14 in the cleaning tank 1 again through the cleaning component, so that the gear part 14 can be flushed and cleaned again and the internal structure of the cleaning tank 1 can be backwashed, thereby achieving thorough degreasing and cleaning of the gear part 14.

[0093] Drying of the gear parts 14: After the secondary cleaning and flushing of a single or multiple gear parts 14 is completed, the high-pressure air pipe 6 can be opened and the high-pressure water pipe 7 can be closed. The high-pressure air pipe 6 is passed with compressed air, and the compressed air is blown directly onto the gear parts 14 through the conduction ring 2, the conduction pipe 28, the conduction box 27 and the flushing mechanism, so that the gear parts 14 can be quickly blown and dried, and the clean water on the gear parts 14 can be initially blown off;

[0094] After the gear 14 is rinsed, the two hydraulic push rods 3 can be started to drive the squeezing plate 13 to move downward. When the squeezing plate 13 moves downward, the middle rod 19 and the pressure plate 15 will be driven downward through the clamping plate 17. The pressure plate 15 moves downward to squeeze the lifting and lowering bearing plate 10 and the alcohol solution at the same time, so that the alcohol solution is poured into the upper part of the lifting and lowering bearing plate 10 through the upper liquid tank 24, and the gear 14 on the upper part of the lifting and lowering bearing plate 10 is immersed. The residual clean water on the gear 14 is sucked away by the alcohol solution, and the gear 14 is further dehydrated.

[0095] After a single or multiple gear parts 14 are soaked, compressed air can be introduced again to blow the gear parts 14 for a second time to blow away the residual alcohol solution on the gear parts 14, complete the thorough drying of the gear parts 14, and then complete the degreasing and cleaning process of the gear parts 14.

[0096] The embodiment of the present invention further provides a method for degreasing a gear workpiece by using a dual-purpose air-water method, which is used in the above-mentioned dual-purpose air-water method for degreasing a gear workpiece, and comprises the following steps:

[0097] S1, placing a plurality of gear parts 14 to be cleaned into the positioning assembly for positioning, and then placing the positioning assembly as a whole into the adjustment assembly in the cleaning tank 1;

[0098] S2, start the cleaning component to pass high-pressure cleaning water to wash the multiple gear parts 14, and adjust the stamping stroke according to the shape of the gear parts 14 to achieve comprehensive cleaning;

[0099] S3, after the wastewater generated during cleaning is separated from the oil and water by the liquid return component, the separated clean water is returned to the cleaning component to rinse the gear part 14 again;

[0100] S4, after cleaning, introduce compressed air to dry the surface of the gear member 14;

[0101] S5, placing the dried gear part 14 into a dehydration assembly for adsorption dehydration, and introducing compressed air again after dehydration to dry the gear part 14 for a second time, thereby completing the purging and drying.
