Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic component cleaning, and specifically relates to a hydraulic component cleaning device. Background Technique

[0002] Hydraulic components are an important part of the hydraulic system. During the processing and production of hydraulic components, burrs, chips, flash, dust, welding slag and oil pollution contaminants often remain on the surface of the hydraulic components. In order to ensure the normal operation of the hydraulic system, it is necessary to clean the hydraulic components before installing them. When cleaning the hydraulic components, a hydraulic component cleaning device is usually used, for example, an ultrasonic cleaning machine.

[0003] However, the cleaning effect of the existing hydraulic component cleaning device is not ideal, and it cannot remove the contaminants on the hydraulic components well. Once the cleaned component touches the cleaning device, the side of the component that touches the cleaning device will not be cleaned. Therefore, it is necessary to flip the uncleaned component to ensure complete cleaning. In addition, the hydraulic components themselves have through holes of different numbers and sizes, and cleaning during the real-time flipping process can ensure the outflow of contaminants in the through holes. Therefore, a cleaning device suitable for hydraulic components is needed to solve these problems. Content of the Utility Model

The first output end of the double-output motor 11 is connected to a second gear 42 arranged in the cleaning chamber 2 through a belt. The second gear 42 is rotationally matched with the cleaning chamber 2. A filter chamber 12 is arranged at the second output end of the double-output motor 11. The filter chamber 12 is communicated with the cleaning chamber 2 and a valve body 13 through a first pipeline. The filter chamber 12 is communicated with the cleaning chamber 2 through a second pipeline to realize circular filtration during the cleaning process; a filter screen 22 is also arranged inside the cleaning chamber 2. Pulling hands higher than the cleaning chamber 2 by a certain distance are arranged on both sides of the filter screen 22 to extract impurities attached to and isolated by the filter screen 22; the cleaning chamber 2 is an ultrasonic cleaning chamber.

[0029] The pressing component 3 includes an upper pressing part and a lower pressing part. The upper pressing part includes a handle 33 and a movable rod 31 movably installed on the cleaning chamber 2, a connecting rod 34 movably installed in the middle sections of the handle 33 and the movable rod 31, and a pressing rod 32 arranged at one end of the movable rod 31. An upper cover 54 is arranged at one end of the pressing rod 32. The same ends of the handle 33 and the movable rod 31 are movably connected to the cleaning chamber 2.

[0030] The lower pressing part includes a conduit 55 installed inside the cleaning chamber 2, a first spring 53 placed inside the conduit 55, a lower cover 52 installed on the first spring 53. The upper cover 54 is provided with a positioning pin 56 inserted into the lower cover 52. A plurality of rollers 51 are arranged at the arc-shaped parts of the upper cover 54 and the lower cover 52. The conduit 55 is threadedly connected to the cleaning chamber 2. The lower cover 52 is slidably matched with the conduit 55.

[0031] The clamping component includes a special-shaped rod 44 disposed between the upper cover 54 and the lower cover 52. One end of the special-shaped rod 44 is provided with a first gear 41, and the other end is sleeved with a sleeve. The sleeve is movably connected to the cleaning chamber 2. Symmetrically arranged in the special-shaped rod are a ejector rod 45 and a screw rod 46. A second spring 43 is provided between the ejector rod 45 and the special-shaped rod 44. The sleeve is rotationally engaged with the special-shaped rod 44. The first gear 41 is in interference fit with the special-shaped rod 44. The ejector rod 45 is slidably engaged with the special-shaped rod 44. A rectangular hole is formed at the mating portion of the special-shaped rod 44 and the ejector rod 45. At the rectangular hole, there is a stud threadedly connected to the ejector rod 45. The screw rod 46 is threadedly connected to the special-shaped rod 44.

[0032] Principle description: First, when the upper cover 54 and the lower cover 52 are not in a mated state, rotate the special-shaped rod 44 with the position of the sleeve as the fulcrum. When the special-shaped rod 44 is perpendicular to the cleaning chamber 2, place the hydraulic components to be cleaned between the screw rod 46 and the ejector rod 45. Adjust the distance for clamping the hydraulic components by moving the stud or rotating the screw rod 46. After adjustment, loosen the stud and under the action of the first spring 53, make the ejector rod 45 contact the hydraulic components.

[0033] After clamping the hydraulic components, rotate the special-shaped rod 44 so that one end of the special-shaped rod 44 contacts the lower cover 52. At this time, the hydraulic components are immersed in the cleaning chamber 2. If the hydraulic components that do not need to be clamped rotate in the cleaning chamber 2, start the cleaning chamber 2 and the dual-output motor 11 at this time. The dual-output motor 11 drives the filter chamber 12 to operate. The filter chamber 12 circulates and filters the liquid in the cleaning chamber 2. The filter net 22 isolates the particles to avoid blocking the pipeline. After cleaning, rotate the special-shaped rod 44 to remove the components.

[0034] When it is necessary to make the components rotate during the cleaning process,

[0035] After one end of the special-shaped rod 44 contacts the lower cover 52, rotate the handle 33 to press the connecting rod 34 against the movable rod 31 and make the pressure rod 32 move towards the upper cover 54. At this time, under the guidance of the positioning pin 56, the upper cover 54 and the lower cover 52 are mated to clamp the special-shaped rod 44. Under the action of the pressure, the lower cover 52 moves in the conduit 55, making the first gear 41 engage with the second gear 42, and making the special-shaped rod 44 rotate slowly under the speed difference state. At this time, there is no need to stop the cleaning chamber 2 and the dual-output motor 11. Make the handle 33 reset, and under the action of the first spring 53, place the special-shaped rod 44 in a position where it can be taken. At this time, remove the cleaned hydraulic components.
