DETAILED DESCRIPTION

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0029] See also Figure 1-6 As shown, a cylinder head internal impurity desorption and cleaning device comprises a cleaning mechanism 1, wherein the cleaning mechanism 1 is arranged according to the number of cleaning inner holes 2, and is used for cleaning the cleaning inner holes 2 at the same time, and the cleaning inner holes 2 are opened at the positions of the cylinder heads 3 to be cleaned. When in use, the positions of the cylinder heads 3 to be cleaned are fixed, and then the cleaning mechanism 1 is longitudinally moved so that the cleaning mechanism 1 acts on the inside of the cleaning inner holes 2, thereby accurately cleaning the inside of the cleaning inner holes 2, and during the cleaning process, the cleaning efficiency can be ensured.

[0030] Furthermore, the cleaning mechanism 1 includes a driving motor 11, wherein the driving motor 11 is installed at the output end of the driving telescopic rod. The existence of the driving telescopic rod is utilized to control the height of the driving motor 11, so that the cleaning component can be utilized to fully clean the cleaning inner hole 2. The existence of the driving motor 11 can enable the cleaning component to rotate inside the cleaning inner hole 2, thereby completely cleaning the cleaning inner hole 2.

[0031] Therefore, in the present application, the fixed support turntable 12 and the driving motor 11 are fixedly connected, and at the same time, the fixed support turntable 12 and the driving telescopic rod are fixedly connected, and the fixed support turntable 12 is used to support and limit the cleaning component below. Therefore, in the present application, the driving motor 11 is used to drive the cleaning component, and the fixed support turntable 12 is used to limit the movement of the cleaning component, thereby realizing the movement limitation of the cleaning component.

[0032] Furthermore, the cleaning component includes a scraper mechanism 14, a cleaning mechanism 13 and a blower mechanism 17, wherein the heights of the scraper mechanism 14, the cleaning mechanism 13 and the blower mechanism 17 are increased sequentially. When in use, the scraper mechanism 14 is first used to scrape the stepped corners inside the cleaning inner hole 2 to remove stubborn impurities, and then the cleaning mechanism 13 is used to sweep and clean the inner wall of the cleaning inner hole 2. When the cleaning mechanism 13 is lowered to the stepped corners inside the cleaning inner hole 2, the cleaning mechanism 13 is used to sweep away the impurities swept at the stepped corners. Finally, when the blower mechanism 17 is lowered to the stepped corners, the wind force applied by the blower mechanism 17 is used to clean the impurities swept out. At the same time, in the present application, the scraper mechanism 14 and the cleaning mechanism 13 are on the same vertical line, and the cleaning mechanism 13 and the blower mechanism 17 are symmetrically arranged in the horizontal direction, so that the blower mechanism 17 can be used to clean the inner hole 2 alone, avoiding the blower mechanism 17 from applying a large wind force to affect the cleaning of the cleaning mechanism 13.

[0033] A connecting rotating rod 16 is fixed to the output end of the driving motor 11, wherein the connecting rotating rod 16 and the fixed supporting turntable 12 are slidably connected, and at the same time, a longitudinal supporting frame 15 is vertically fixedly installed on the connecting rotating rod 16, and a scraper mechanism 14 is installed on the longitudinal supporting frame 15. A cleaning mechanism 13 and a blower mechanism 17 are respectively installed at both ends of the connecting rotating rod 16. When in use, the driving motor 11 is used to drive the connecting rotating rod 16, thereby driving the rotation of the cleaning mechanism 13, the scraper mechanism 14 and the blower mechanism 17, so as to achieve sufficient cleaning of the inner hole 2.

[0034] In order to realize the sliding limit of the connecting rotating rod 16 and the fixed support turntable 12, a side annular support frame 19 is fixedly installed on the fixed support turntable 12 through a fixed support frame 18, wherein a first support seat 171 and a second support seat 131 are respectively fixed at both ends of the connecting rotating rod 16, wherein a matching sliding seat 172 is respectively fixed on the first support seat 171 and the second support seat 131, and the matching sliding seat 172 is slidingly connected to the side annular support frame 19, and the sliding trajectory of the matching sliding seat 172 is circular, which is used to realize the driving of the cleaning mechanism 13, the scraper mechanism 14 and the blower mechanism 17, so as to facilitate the use of the cleaning mechanism 13, the scraper mechanism 14 and the blower mechanism 17 to fully clean the cleaning inner hole 2.

[0035] In the present application, the blower mechanism 17 includes a first guide cover 175, wherein the first guide cover 175 is fixedly mounted on a first support seat 171, wherein a first connecting plate 173 is fixed on the first support seat 171, and a plurality of first nozzles 174 are evenly fixed on the first connecting plate 173, wherein the first nozzle 174 is connected to the output end of the output air pump, and the output air pump outputs high air pressure, so that the first nozzle 174 is used to spray the gas, and the gas is directly applied to the side wall of the cleaned inner hole 2, and the impurities adhered to the cleaned inner hole 2 are sprayed out with high pressure. During the spraying process, the impurities are very likely to rebound, so in the present application, a first bucket-shaped groove 176 is provided on the first guide cover 175, that is, when in use, the impurities are impacted on the first bucket-shaped groove 176. Since the first bucket-shaped groove 176 is bucket-shaped, the impurities will produce reflections with a certain angle, which can prevent the impurities from being blown to the step corners, thereby ensuring the normal discharge of impurities.

[0036] Furthermore, the cleaning mechanism 13 includes a second driving motor 132, which is fixedly mounted on the second supporting seat 131. At the same time, a second cleaning turntable 134 is fixed to the output end of the second driving motor 132, and a plurality of second cleaning brushes 133 are evenly arranged on the side of the second cleaning turntable 134. Therefore, when in use, the second cleaning turntable 134 is driven to rotate by starting the second driving motor 132, thereby driving the second cleaning brush 133 to act on the inner wall of the cleaning inner hole 2. In this process, since the material of the second cleaning brush 133 is soft, even if the inner diameter of the cleaning inner hole 2 changes in a step-like manner, it can be suitable for cleaning inner holes 2 of various sizes, thereby ensuring the applicability of the device.

[0037] As a further embodiment of the present application, the scraper mechanism 14 includes an end scraper 1410, wherein the height of the end scraper 1410 is adjustable, and the lateral position of the end scraper 1410 is adjustable. When in use, the height of the end scraper 1410 is adjusted so that the end scraper 1410 can be tightly attached to the stepped step of the cleaning inner hole 2, and then the lateral position of the end scraper 1410 is adjusted so that the end of the end scraper 1410 can be tightly attached to the inner wall of the cleaning inner hole 2, so that when the end scraper 1410 is able to rotate under the action of the drive motor 11, the end scraper 1410 can accurately clean the stubborn impurities adhered to the inner wall of the cleaning inner hole 2, thereby ensuring the cleanliness of the inner wall of the cleaning inner hole 2.

[0038] Furthermore, the end scraper 1410 is fixedly mounted on a pushing bracket 1411, and the pushing bracket 1411 is fixedly mounted on a pushing slider 1412, and the pushing slider 1412 is slidably connected to a pushing slot 149, and the pushing slot 149 is opened on the end support frame 148, and a pushing spring 1413 is also arranged inside the pushing slot 149, wherein a second hinged rotating rod 1414 is also rotatably arranged on the side of the pushing slider 1412, and a first hinged rotating rod 1414 is rotatably arranged on the end support frame 148. A hinged rotating rod 147, the first hinged rotating rod 147 and the second hinged rotating rod 1414 are rotatably connected, and the height of the end support frame 148 is adjustable. A limited position matching support frame 1415 is fixedly installed on the longitudinal support frame 15, and the limited position matching support frame 1415 cooperates with the rotation connection part of the first hinged rotating rod 147 and the second hinged rotating rod 1414, that is, when the first hinged rotating rod 147 and the second hinged rotating rod 1414 are adjusted in height, the first hinged rotating rod 147 and the second hinged rotating rod 1414 are adjusted in height. The rotating connection part of the rotating rod 1414 is gradually pressed on the limit matching support frame 1415, and the rotating connection part of the first hinged rotating rod 147 and the second hinged rotating rod 1414 is pressed downward. At this time, the push slider 1412 slides horizontally under the action of the second hinged rotating rod 1414, overcoming the elastic force of the push spring 1413, so that the end scraper 1410 slides horizontally until the end scraper 1410 contacts the stepped inner wall of the cleaning inner hole 2, thereby ensuring that the end scraper 14 10 is pressed on the stepped platform of the cleaning inner hole 2 with a certain pressure, and at the same time, the end scraper 1410 is pressed on the stepped inner wall of the cleaning inner hole 2 with a certain pressure, so as to facilitate the use of the end scraper 1410 to directly and accurately clean the cleaning inner hole 2, thereby avoiding the problem of scratches on the inner wall of the cleaning inner hole 2 caused by the end scraper 1410 directly pressing on the inner wall of the cleaning inner hole 2 for longitudinal sliding. The present application only scrapes on the stepped platform to ensure the integrity of the cleaning inner hole 2.

[0039] In order to be suitable for cleaning multiple stepped platforms inside the same cleaning inner hole 2, the end support frame 148 in the present application is fixedly mounted on the end base 146, and the end base 146 is fixedly mounted on the limiting telescopic rod 145, and the limiting telescopic rod 145 is fixedly mounted on the limiting support base 144. When in use, the limiting telescopic rod 145 is used to clean the stepped platforms inside the cleaning inner hole 2 of different sizes at different heights, so that the present application can be suitable for cleaning inner holes 2 of different sizes, thereby ensuring sufficient cleaning of the cleaning inner hole 2.

[0040] In order to realize the longitudinal movement of the end scraper 1410, the limit support base 144 in the present application is fixedly installed on the limit slider, and a limit slide groove 143 is opened on the longitudinal support frame 15, wherein the limit slide groove 143 and the limit slider are slidably connected, and a limit internal spring 142 is fixed inside the limit slide groove 143, and one end of the limit internal spring 142 is fixed inside the limit slide groove 143, and the other end is fixed on the limit slider. In the present application, the limit slider is used to slide inside the limit slide groove 143 to overcome the elastic force of the limit internal spring 142 to realize the longitudinal sliding of the end scraper 1410.

[0041] When the present invention is used, the position of the cylinder head 3 to be cleaned is first fixed, and then the cleaning mechanism 1 is longitudinally moved so that the cleaning mechanism 1 acts on the inside of the cleaning inner hole 2, thereby accurately cleaning the inside of the cleaning inner hole 2;

[0042] Specifically, when in use, the longitudinal height of the cleaning mechanism 1 is controlled by driving the telescopic rod, so that the cleaning mechanism 1 is stably and gradually moved toward the inside of the cleaning inner hole 2, and during the movement, the driving motor 11 is stably started to rotate the connecting rotating rod 16, and the cleaning mechanism 13, the scraper mechanism 14 and the blower mechanism 17 are controlled to clean the inner wall of the cleaning inner hole 2 during the rotation process. In this process, the sliding seat 172 and the side annular support frame 19 are slidably connected, and the sliding track of the sliding seat 172 is circular, which is used to realize the driving of the cleaning mechanism 13, the scraper mechanism 14 and the blower mechanism 17;

[0043] When cleaning the stepped platform in the cleaning inner hole 2, first, the end scraper 1410 contacts the edge of the stepped platform, and then the rotating connection parts of the first hinged rotating rod 147 and the second hinged rotating rod 1414 are gradually squeezed on the limit matching support frame 1415, and under the action of the driving telescopic rod, the cleaning mechanism 1 moves downward stably. At this time, the rotating connection parts of the first hinged rotating rod 147 and the second hinged rotating rod 1414 are pressed downward, and the pushing slider 1412 slides laterally under the action of the second hinged rotating rod 1414, overcoming the elastic force of the pushing spring 1413, so that the end scraper 1410 slides laterally until the end scraper 1410 contacts the stepped inner wall of the cleaning inner hole 2, thereby ensuring that the end scraper 1410 is squeezed on the stepped platform of the cleaning inner hole 2 with a certain pressure, and at the same time, the end scraper 1410 is squeezed on the stepped inner wall of the cleaning inner hole 2 with a certain pressure, so that the end scraper 1410 is used to directly and accurately clean the cleaning inner hole 2;

[0044] After the scraper mechanism 14 finishes cleaning, the cleaning mechanism 13 is lowered to the stepped platform position, and the second cleaning rotary disc 134 is driven to rotate by the start of the second driving motor 132, thereby driving the second cleaning brush 133 to act on the inner wall of the cleaning inner hole 2. In this process, since the material of the second cleaning brush 133 is soft, even if the inner diameter of the cleaning inner hole 2 changes in a stepped manner, it can be applied to cleaning inner holes 2 of various sizes, thereby ensuring the applicability of the device;

[0045] Finally, the blower mechanism 17 is moved longitudinally so that it acts on the stepped platform, that is, the output air pump is used to output high air pressure, so that the first nozzle 174 is used to spray the gas, and the gas is directly applied to the side wall of the cleaned inner hole 2, thereby removing impurities adhered to the cleaned inner hole 2 by high-pressure spraying.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
