For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection, it may be directly connected, or indirectly connected through an intermediate medium, it may be the communication inside two components, or a "transmission connection", that is, a power connection is made through various suitable methods such as belt drive, gear drive or sprocket drive. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] The following will further describe the device for cleaning the residues in the automatic transmission valve body of the present invention with reference to the attached Figures 1-12 drawings.

[0050] Please refer specifically to Figure 1 , Figure 4 and Figures 7-9 , the present invention provides a device for cleaning the residues in the automatic transmission valve body, including a frame-shaped rack 10 as a whole. An upper cover assembly 20 is fixedly installed on the rack 10. The upper cover assembly 20 includes a cover body 21 with an open lower part. The cover body 21 is integrally a rectangular frame shape surrounded by a top wall 211, a front side wall 212, a rear side wall 213, a left side wall 214 and a right side wall 215. The lower part of the cover body 21 is an open end 216. A top spray head assembly 22, a front spray head assembly 23 and a rear spray head assembly 24 are respectively arranged on the inner sides of the top wall 211, the front side wall 212 and the rear side wall 213. A left air duct assembly 25 and a right air duct assembly 26 are respectively arranged on the outer sides of the left side wall 214 and the right side wall 215. The left air duct assembly 25 communicates the inside of the cover body 21 with the external space of the cover body 21. The right air duct assembly 26 communicates the inside of the cover body 21 with the external space of the cover body 21. A lifting platform assembly 30 is arranged directly below the cover body 21. A bottom spray head assembly 31 is arranged on the upper part of the lifting platform assembly 30. A positioning tooling 32 is arranged on the upper part of the lifting platform assembly 30. The positioning tooling 32 includes an outer frame 321 and a top bracket arranged above the outer frame 321 and fixedly connected to the outer frame 321. The top bracket includes a plurality of positioning rods 322 arranged vertically. The outer frame 321 is installed on the lifting platform assembly 30 and the outer frame 321 surrounds the bottom spray head assembly 31. A lifting assembly 40 for driving the lifting platform assembly 30 to lift is arranged below the lifting platform assembly 30.

[0051] More specifically, the top nozzle assembly 22, the front nozzle assembly 23, the rear nozzle assembly 24, and the bottom nozzle assembly 31 each include a plurality of jet nozzles 50. The jet nozzles 50 are connected to external high-pressure gas and are used to jet high-pressure gas to the middle position of the cover body 21 to carry away impurities and achieve cleaning. The jet nozzles 50 in each nozzle assembly (the top nozzle assembly 22, the front nozzle assembly 23, the rear nozzle assembly 24, or the bottom nozzle assembly 31) are arranged in rows, which can be one row or multiple rows. During specific implementation, according to needs, the opening sequence of the nozzle assemblies can be controlled separately, or the jet nozzles 50 in each nozzle assembly can be controlled to open in sequence, so as to achieve directional impurity removal.

[0052] It should be noted that the front, rear, left, right, up, and down directions mentioned in the present invention all refer to Figure 2 the direction of

[0053] In this embodiment, the structural design of the positioning tooling 32 needs to meet at least three requirements: First, it is necessary to ensure that it is conducive to the loading of the valve body 100. In this embodiment, the positioning rod 322 is inserted into the mounting hole on the valve body 100 to achieve the positioning of the valve body 100, and the valve body 100 is fixed by its own weight. Second and third, it is necessary to ensure that the positioning tooling 32 is fixed on the lifting platform assembly 30 and does not block the jet flow of the bottom nozzle assembly 31. In this embodiment, the above requirements are met through the following structure: The outer frame 321 is installed on the lifting platform assembly 30, and the outer frame 321 surrounds the bottom nozzle assembly 31.

[0054] The specific position of the positioning rod 322 needs to be correspondingly set according to the structure of the valve body 100 to be cleaned. The size and position of the positioning rod 322 are designed based on the position and size of the valve body mounting hole on the valve body 100.

[0055] During use, the valve body 100 to be cleaned is placed on the positioning tooling 32, and the lifting assembly 40 drives the lifting platform assembly 30 to move upward. When it stops when the top of the lifting platform assembly 30 fits with the lower part of the cover body 21, at this time, the cover body 21 and the lifting platform assembly 30 jointly enclose a cleaning chamber. The top nozzle assembly 22, the front nozzle assembly 23, the rear nozzle assembly 24, and the bottom nozzle assembly 31 respectively jet high-pressure gas from the top, front, rear, and bottom of the valve body 100. By using the high-pressure gas to jet at a fixed point, the impurities are separated from the valve body 100. In this way, the processed residues (such as aluminum chips, burrs, flash, cleaning liquid residues, etc.) in the internal channels of the valve body 100 can be removed, and the treatment of stubborn impurities can be achieved. Ensure the cleanliness of the valve body 100 and avoid affecting the normal operation of the transmission due to impurities in the valve body 100.

[0056] During the cleaning operation, under the action of continuous high-pressure gas, the high-pressure gas in the cleaning chamber carries impurities and is discharged through the left air duct assembly 25 and the right air duct assembly 26, which can achieve pressure relief and timely remove impurities, avoid the backflow of the blown impurities to the valve body 100, and improve the impurity removal effect while ensuring safety.

[0057] According to a specific embodiment of the present invention, the lifting platform assembly 30 further includes a bottom plate 33 and a top plate 34 fixed to the bottom plate 33 by threaded connectors. Two parallel and spaced nozzle mounting grooves 331 are provided on the bottom plate 33, and the nozzle mounting grooves 331 penetrate through the bottom plate 33. The bottom nozzle assembly 31 includes two nozzle mounting seats 311, and a plurality of air nozzles 50 are installed on each nozzle mounting seat 311. The two nozzle mounting seats 311 are respectively installed in the two nozzle mounting grooves 331. A nozzle through hole 341 penetrating through the top plate 34 in the vertical direction is provided in the middle of the top plate 34, and the outer frame 321 is fixed to the top plate 34 and arranged around the edge of the nozzle through hole 341.

[0058] In this embodiment, by designing the lifting platform assembly 30 in a split manner, it is beneficial to reduce the difficulty of processing and assembly, and at the same time is beneficial to the disassembly and assembly of related parts. Specifically: during assembly, first install a plurality of air nozzles 50 on the nozzle mounting seats 311 respectively to form a single spray group unit. In order to ensure the installation of the air nozzles 50 under the condition of a small spacing, the installation angles of adjacent air nozzles 50 can be set differently, and one air nozzle 50 rotates a certain angle relative to the previous air nozzle 50. In this way, it can be ensured that there is no interference between the air nozzle joints, and at the same time it is beneficial to the installation of the air pipe. In this embodiment, by providing the nozzle mounting grooves 331, the single spray group unit can be directly aligned with the nozzle mounting grooves 331 for installation, which can improve the installation accuracy and efficiency. At the same time, when maintenance is required later, the unit spray group unit can be removed as a whole for maintenance. The nozzle through hole 341 provided on the top plate 34 is used to avoid the top plate 34 blocking the air flow and facilitate the air nozzles 50 to spray towards the valve body 100.

[0059] More specifically, the shape formed by arranging a plurality of air nozzles 50 is rectangular, and the nozzle through hole 341 is a rectangular hole. The overall shape of the valve body 100 is rectangular.

[0060] Please refer to Figure 11 , according to a specific embodiment of the present invention, the nozzle mounting grooves 331 are rectangular, the nozzle mounting seats 311 are rectangular columns matching the shape of the nozzle mounting grooves 331, and the bottom nozzle assembly 31 further includes connecting columns 312 provided on the bottom plate 33 and respectively connecting the two nozzle mounting seats 311. There are two connecting columns 312, and the two connecting columns 312 are respectively fixed to the bottom plate 33 by threaded connectors.

[0061] Please refer to Figure 12, according to the specific embodiments of the present invention, a sunken annular groove 342 is provided on the top plate 34. The shape of the annular groove 342 is matched with the shape of the lower part of the cover body 21, and the annular groove 342 is arranged facing the lower contour of the cover body 21.

[0062] In this embodiment, when the device is performing a cleaning operation, under the action of the lifting assembly 40, the lower edge of the cover body 21 just extends into the annular groove 342. By providing the annular groove 342, the sealing performance between the lower part of the cover body 21 and the top plate 34 can be improved, and gas ejection can be reduced.

[0063] Please refer to Figure 5 , according to the specific embodiments of the present invention, the upper cover assembly 20 further includes a rear side air duct assembly 27 provided outside the rear side wall 213. The rear side air duct assembly 27 communicates the inside of the cover body 21 and the external space of the cover body 21.

[0064] In this embodiment, the function of the rear side air duct assembly 27 is similar to that of the left side air duct assembly 25 and the right side air duct assembly 26, and can achieve pressure relief and timely removal of impurities. After adding the rear side air duct assembly 27, an additional position for impurity discharge is added, and the direction of impurity discharge is different from that of the left side air duct assembly 25 and the right side air duct assembly 26. In this way, the efficiency and timeliness of impurity discharge can be further improved.

[0065] Please refer to Figure 10 , according to the specific embodiments of the present invention, the left side air duct assembly 25 and the right side air duct assembly 26 are symmetrical structures. The left side air duct assembly 25 and the rear side air duct assembly 27 both include an air outlet hood 251 and an air outlet pipe 252. The air outlet hood 251 is in a horn shape as a whole. A hood connection flange 253 is provided at the large head end of the air outlet hood 251. The small head end of the air outlet hood 251 is communicated with the air outlet pipe 252. An air outlet hole 2141 penetrating through the left side wall 214 of the cover body 21 and having a shape matched with the large head end of the air outlet hood 251 is provided. The air outlet hood 251 completely covers the air outlet hole 2141, and the air outlet hood 251 is fixed to the cover body 21 through the hood connection flange 253.

[0066] In this embodiment, by providing the horn-shaped air outlet hood 251, the space of the cleaning cavity can be expanded, and horn-shaped impurity collection spaces are formed on the left side, right side, and rear wall of the cleaning cavity. With the horn-shaped structure, on the one hand, it is beneficial for the high-pressure gas to be discharged in time along the air outlet hood 251. On the other hand, it is also beneficial for the collection and discharge of impurities. After the impurities are blown to the inner wall of the air outlet hood 251, restricted by the inner wall of the air outlet hood 251, it is difficult for the impurities to run out of the air outlet hood 251 and flow back to the valve body 100. Under the continuous action of the pressure gas, the impurities are discharged along the air outlet hood 251 through the air outlet pipe 252 and discharged outside the cover body 21.

[0067] During specific implementation: The air outlet pipes 252 in the left air duct assembly 25 and the right air duct assembly 26 are right-angle pipes, while the air outlet pipe in the rear air duct assembly 27 is a straight pipe. In this way, it can be ensured that the outlets of the three air outlet pipes 252 are in the same direction, which is beneficial to the centralized treatment of the three-way discharged air and impurities.

[0068] Please refer to Figure 7 , according to the specific implementation manner of the present invention, the top bracket further includes a first side bracket 323 and a second side bracket 324 fixed directly above both sides of the outer frame 321. The first side bracket 323 is in the shape of a gantry as a whole, and the second side bracket 324 is in the shape of a gantry as a whole; both ends of the second side bracket 324 extend in the direction of the first side bracket 323 with a straight support rod 325 and a bent support rod 326 respectively; the number of positioning rods 322 is five. Two positioning rods 322 are respectively provided at both ends of the top of the first side bracket 323, one positioning rod 322 is provided in the middle of the top of the second side bracket 324, one positioning rod 322 is provided at the end of the straight support rod 325 away from the second side bracket 324, and two positioning rods 322 are provided on the bent support rod 326.

[0069] More specifically, one positioning rod 322 is respectively provided at the end and the bending part of the bent support rod 326. In this embodiment, the first side bracket 323 and the second side bracket 324 are used to fix the positioning rods 322 at the required positions, and at the same time, they also do not avoid blocking the jet flow of the jet nozzle 50.

[0070] According to the specific implementation manner of the present invention, each positioning rod 322 is inserted and fixed to the top bracket; a locking screw 327 is further provided on the side of some positioning rods 322. The locking screw 327 passes through the top bracket and abuts against the positioning rod 322 along the radial direction of the positioning rod 322.

[0071] In this embodiment, five positioning rods 322 are provided, and each positioning rod 322 is detachable. In this way, according to the installation requirements of different valve bodies, the positioning rods 322 to be installed can be selected. With this structure, the positioning installation of a variety of different valve bodies can be realized, greatly expanding the application range of the present invention. The added locking screw 327 can further improve the stability of the connection of the positioning rod 322.
