DETAILED DESCRIPTION

[0044] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0045] Example 1

[0046] One embodiment of the present invention provides a cleaning system, such as Figure 1As shown, it includes a clamp unit 2, a cleaning liquid injection device 3, a filtering unit 5 and a detection device 6.

[0047] The fixture unit 2 in this embodiment is a first fixture structure 21, such as Figure 2 As shown, the first clamp structure 21 includes a bottom plate 211 , a support plate 212 , a rib plate 213 , a lower clamp 214 , an upper clamp 215 and bolts 216 .

[0048] A support plate 212 is vertically fixed in the middle of the bottom plate 211, and ribs 213 are symmetrically arranged on both sides to provide support for the support plate 212. It should be noted that the support plate 212 and the ribs 213 have various heights to match the height of the lower contact surface of the workpiece 1.

[0049] The lower clamp 214 is disposed at the upper end of the support plate 212, and is used to clamp the workpiece 1 in combination with the upper clamp 215. The upper clamp 215 and the lower clamp 214 have protrusions at both ends, and a threaded hole is disposed in the middle of the protrusions. The protrusions of the upper clamp 215 and the protrusions of the lower clamp 214 are aligned, and the workpiece 1 is fixed by inserting bolts 216.

[0050] Furthermore, in this embodiment, a plurality of fixtures are provided, and the heights of the support plates 212 and the rib plates 213 in each fixture are different to accommodate the lower contact surfaces of the workpieces 1 of different heights.

[0051] Since the heights of the lower contact surfaces of the workpieces 1 are different, the present embodiment provides support plates 212 and rib plates 213 structures of different heights so that the fixture can adapt to different workpieces, thereby improving the adaptability of the fixture to workpieces of different heights.

[0052] The cleaning liquid injection device 3 is used to inject cleaning liquid into the workpiece 1 for cleaning. Before injection, the liquid inlet and liquid outlet in the cleaning liquid injection device 3 need to be connected for self-circulation, and the cleaning liquid is injected into the workpiece 1 after reaching the required cleanliness.

[0053] Furthermore, an air filling device 4 is provided. The air filling device 4 is used to fill the workpiece 1 with compressed gas to mix with the cleaning liquid during the cleaning process of the workpiece 1. The compressed gas can accelerate the flow speed of the cleaning liquid, form a vortex, increase the flushing force on the cleaning part, and improve the cleaning quality.

[0054] Compared with the prior art, the present embodiment is provided with an air charging device 4, which is used to charge compressed gas into the workpiece 1 during the cleaning process of the workpiece 1, so as to push the cleaning liquid to flow more quickly in the complex structure inside the workpiece 1, forming a vortex, and better flushing various parts inside the workpiece 1. The compressed gas is charged into the cleaning liquid to form bubbles, and the impact force generated after the bubbles burst hits the inner wall of the workpiece 1, so that the impurities attached to the inner wall and the deposited pollutants fall off and are taken out of the workpiece 1 with the cleaning liquid, thereby improving the cleaning quality and efficiency.

[0055] like Figure 3 As shown, the filter unit 5 includes a filter component 51 , a surplus material collecting component 52 and a cleaning liquid collecting component 53 .

[0056] In this embodiment, the filter assembly 51 includes a first filter component 511, a second filter component 512, and a third filter component 513. The first filter component 511, the second filter component 512, and the third filter component 513 are arranged from top to bottom, and the filtering accuracy increases in sequence. The first filter component 511 is a coarse filter, and exemplarily, the filtering accuracy is 15mm; the second filter component 512 is a medium filter, and exemplarily, the filtering accuracy is 1mm; the third filter component 513 is a fine filter, and exemplarily, the filtering accuracy is 5um.

[0057] In this embodiment, the filter assembly 51 is configured as a three-layer filter component stacked combination, which can filter particles of different levels and reduce the accumulation of particles in the filter components. The cleaning liquid discharged from the workpiece 1 is filtered by the multi-layer filter components, which can effectively prevent impurities of different sizes from passing through, improve the filtering accuracy, and ensure that the quality of the cleaning liquid meets the requirements for recycling.

[0058] In order to facilitate the collection of excess matter, the first filter component 511, the second filter component 512 and the third filter component 513 are all hollow mesh structures with an arc-shaped concave surface in the middle, so that the excess matter can be collected in the middle of the filter component. Furthermore, each filter component is tilted so that the excess matter can slide to the lower end of the filter screen by gravity.

[0059] The excess collection assembly 52 is arranged at the lower end of the filter component, and is used to collect the excess filtered out of the filter component. The excess collection assembly 52 comprises an excess collection bucket 521 and a collection bucket placement frame 5211. The excess collection bucket 521 can be inserted into the collection bucket placement frame 5211 to be fixed.

[0060] like Figure 4 As shown, the cleaning liquid collection assembly 53 includes a liquid collecting pool 531 and a liquid collecting box 532. The liquid collecting pool 531 is tilted by raising one end with a pad 533, so that the collected filtered cleaning liquid flows into the liquid collecting box 532. The liquid collecting box 532 is provided with a liquid outlet pipe 5321, which can be passed into the cleaning liquid injection device 3 for recycling.

[0061] Furthermore, the filter unit 5 further comprises a dumping assembly 54 . The dumping assembly 54 is symmetrically arranged on both sides of the filter component, and comprises a filter component placement frame 541 , a rotating shaft 542 , a pressing plate 543 and a rocker arm 544 .

[0062] Both ends of the filter component are arranged on the filter component placement frame 541 and are hinged to the filter component placement frame 541. Pressing plates 543 are arranged on both sides of the filter component. The pressing plate 543 is an L-shaped plate, one side of the pressing plate 543 is fitted and fixed to the planes on both sides of the filter component, and the other side is hinged to the filter component placement frame 541 through a rotating shaft 542. When the pressing plate 543 is rotated, the filter component rotates accordingly.

[0063] Furthermore, a rocker arm 544 is provided on the other side of the filter component placement rack 541, and the rocker arm 544 is coaxially arranged with the pressing plate 543 and can rotate simultaneously. When it is necessary to dump the excess, the rocker arm 544 is rotated to make the pressing plate 543 press down the filter component, the filter component is tilted, and the excess in the filter component enters the excess collection bucket 521.

[0064] Compared with the prior art, the filter component in this embodiment is tilted, and the middle of the filter component is concave, etc., which is convenient for collecting the filtered excess. The rocker arm 544 and the pressing plate 543 are arranged to press the filter component, so that the filter component rotates to dump the collected excess, which is easy to operate.

[0065] Furthermore, since the filtering accuracy in the third filter component 513 is high and the pores are very small, some small excess materials such as iron filings brought out by the cleaning oil will adhere to the third filter component 513, resulting in a decrease in the filtering effect. The filter unit 5 of this embodiment is also provided with a scraper assembly 55 for scraping the small excess materials adhered to the third filter component 513 into the excess material collection bucket 521.

[0066] The scraper assembly 55 includes a scraper frame 551, a scraper rod 552 and a scraper 553. The scraper assembly 55 is arranged at the end of the third filter component 513. There is a through hole in the middle of the scraper frame 551, and the scraper rod 552 can be inserted into the through hole. The curvature of the bottom of the scraper 553 is the same as the curvature of the middle part of the third filter component 513.

[0067] Compared with the prior art, the present embodiment is provided with a scraper assembly 55 for scraping small excess materials adhered to the third filter component 513 into the excess material collecting bucket 521, so as to prevent the excess materials from accumulating and blocking the mesh of the filter component and reduce the excess materials remaining in the filter component.

[0068] Furthermore, it also includes a detection device 6 for detecting the cleanliness and cleaning effect of the kerosene cleaning medium.

[0069] Example 2

[0070] The difference between this embodiment and the first embodiment is that the second clamp structure 22 is used in this embodiment to replace the first clamp structure 21. The first clamp structure 21 in the first embodiment uses a clamp to fix the workpiece 1. Different clamps are used for different diameters of the workpiece 1. Since the shape of the workpiece 1 is semicircular, circular or other shapes, the height of the support plate 212 used is different. Different clamps and clamps need to be replaced according to the workpieces 1 of different diameters.

[0071] like Figure 5 As shown, the second fixture structure 22 includes a fixed plate 221, a guide column 222, a guide sleeve 223 and a support plate 224. The guide column 222 and the guide sleeve 223 are installed on both sides of the fixed plate 221. The guide sleeve 223 is sleeved on the guide column 222 and can move up and down along the guide column 222. The support plate 224 is fixed on the upper part of the guide sleeve 223, and the support plate 224 can move up and down together with the guide sleeve 223.

[0072] The second clamp structure 22 also includes a ball joint 226, a ball joint rod 2261 and a clamp mounting plate 227 fixed to the ball joint rod 2261. A ball joint support 2241 is provided in the middle of the support plate 224, and the ball joint 226 is provided in the ball joint support 2241, and can rotate in multiple directions in the ball joint support 2241, driving the clamp mounting plate 227 to rotate in multiple directions.

[0073] Furthermore, the second clamp structure 22 is also provided with a limit plate 225 for limiting the rotation angle of the ball joint 226. The limit plate 225 is installed on the upper part of the support plate 224, and a limit hole 2251 is provided corresponding to the position of the ball joint support 2241, and the ball joint rod 2261 can pass through the limit hole 2251. Furthermore, the diameter of the limit hole 2251 is larger than the diameter of the ball joint 226. When the ball joint 226 rotates in the ball joint support 2241, the ball joint rod 2261 rotates inside the limit hole 2251 to limit the swing amplitude of the ball joint 226.

[0074] When cleaning the inside of the workpiece, on the one hand, the rotation of the ball joint 226 causes the workpiece 1 and the cleaning liquid inside the workpiece 1 to swing left and right, front and back; on the other hand, the up and down movement of the guide column 222 and the guide sleeve 223 can realize the up and down swinging of the workpiece 1 and the fixture. Therefore, the workpiece 1 in this embodiment can be shaken up, down, left, right, front and back to thoroughly clean the blind spots inside the workpiece 1.

[0075] Compared with the prior art, the present embodiment is provided with a ball joint 226, and the ball joint 226 can swing back and forth and left and right in the ball joint support 2241, and the lifting and lowering of the guide column 222 and the guide sleeve 223 can realize the up and down, left and right, and front and back swinging of the workpiece, so that the cleaning liquid inside the workpiece 1 swings on the inner wall of the workpiece 1 and collides with the inner wall, so that the excess materials attached to the inner wall are peeled off and enter the cleaning liquid, and are taken out of the workpiece 1 by the cleaning liquid, thereby improving the cleaning efficiency and cleaning depth of the workpiece 1.

[0076] like Figure 6 As shown, further, in order to adapt to clamps of different diameters, a slide groove 2271 is provided on the upper part of the clamp mounting plate 227, and the length direction of the slide groove 2271 is the same as the length direction of the clamp mounting plate 227. The lower clamp 214 is designed to be split into two halves. The bottom of the lower clamp 214 has a slider, which can drive the lower clamp 214 to slide on the slide groove 2271, so that the distance between the two sides of the lower clamp 214 becomes larger or smaller, so as to adapt to workpieces 1 of different diameters.

[0077] The upper clamp 215 is designed to be divided into two halves. A screw is provided in the middle of the upper clamp 215, and the screw is screwed with the upper clamps 215 on both sides. By rotating the screw, the distance between the two sides of the two upper clamps 215 becomes larger or smaller to adapt to workpieces 1 of different diameters. Long bolts 216 are provided on both sides of the upper clamp 215 and the lower clamp 214 for connecting and fixing the upper clamp 215 and the lower clamp 214.

[0078] Compared with the prior art, the present embodiment is provided with a guide column 222 and a guide sleeve 223 lifting structure, so that the clamp mounting plate 227 can be lifted and lowered, so that the fixture can adapt to workpieces 1 with lower support surfaces of different heights. The upper clamp 215 and the lower clamp 214 are evenly divided into half structures, and a screw is provided in the middle of the upper clamp 215 to adjust the distance between the two sides of the upper clamp 215; a slider is provided at the lower part of the lower clamp 214, which can move in the slide groove 2271 of the clamp mounting plate 227 to adjust the distance between the two sides of the lower clamp 214; the distance between the upper clamp 215 and the lower clamp 214 is adjusted by bolts 216 provided on the two sides, so as to realize the fixation of workpieces 1 with different diameters and workpieces 1 with lower contact surfaces of different heights, and improve the adaptability of the fixture to the diameter and height of the workpiece 1.

[0079] When fixing the workpiece 1, the distance between the two sides of the lower clamp 214 is adjusted by sliding the two lower clamps 214 in the slide groove 2271. After adapting to the diameter of the workpiece 1, the workpiece 1 is placed on the lower clamp 214 and fixed. The upper clamp 215 is buckled on the top of the workpiece 1, and the screw between the two upper clamps 215 is adjusted to the diameter of the workpiece 1 and then fixed. The upper and lower clamps 214 are fixed with bolts 216.

[0080] Because the clamp and the workpiece 1 are fixed to the clamp mounting plate 227. The clamp mounting plate 227 is connected to the support plate 224 through the ball joint 226, and the support plate 224 can rise and fall with the guide sleeve 223, so as to adapt to the height of the lower contact surface of the workpiece 1.

[0081] The ball joint 226 at the lower part of the clamp mounting plate 227 can rotate up, down, left, right, front and back in the ball joint support 2241, driving the clamp and the workpiece 1 to rotate. Due to the limit of the limit hole 2251, the swing angle of the clamp and the workpiece 1 is within a limited range.

[0082] When the workpiece 1 rotates, the cleaning liquid inside the workpiece 1 shakes therewith, collides with the inner wall of the workpiece 1, and washes away the excess matter on the inner wall of the workpiece 1, so that the excess matter enters the cleaning liquid and is finally discharged together with the cleaning liquid.

[0083] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
