Description

Technical Field

[0001] This invention relates to the field of cleaning machine tank manufacturing technology, specifically to a flange and flaring device and method for the vertical cylinder of a cleaning machine tank. Background Technology

[0002] The tank body is the main component of the water tank type cleaning machine. For example, the Chinese utility model patent disclosed in patent application number CN202221382130.2 (publication number CN217679451U) entitled "A Water Tank and Cleaning Machine" includes a rim, a vertical cylinder and a tank bottom connected from top to bottom. The bottom edge of the rim and the top edge of the vertical cylinder are connected by a flange interlocking, and the bottom edge of the vertical cylinder and the top edge of the tank bottom are connected by a flange interlocking.

[0003] Because of the need for flanging and interlocking, the upper end of the vertical tube needs to be flanged or flared to interlock with the surrounding edge, and the lower end of the vertical tube needs to be flanged or flared to interlock with the bottom of the trough.

[0004] When processing vertical cylinders, such as flanging or flaring the ends of the cylinders, it is currently common to use dedicated flanging equipment and dedicated flaring equipment to perform the flanging or flaring of the cylinders respectively. This involves a lot of equipment, takes up space, and requires changing the corresponding equipment according to the operation, which is quite troublesome. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a flange and flaring device for the vertical cylinder of a cleaning machine tank with fewer components, in light of the current state of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a method for flanging and flaring the vertical cylinder of the above-mentioned cleaning machine tank, in view of the current situation of the prior art.

[0007] The technical solution adopted by the present invention to solve the first technical problem mentioned above is as follows: a flange and flaring device for the vertical cylinder of a cleaning machine tank, including a flange and flaring mechanism, the flange and flaring mechanism including a mounting base, a first power source and a second power source, the mounting base can move under the action of the first power source, the bottom of the mounting base is provided with a flaring wheel, a beveling wheel and a flattening wheel, the flaring wheel, the beveling wheel and the flattening wheel are evenly spaced along the same circular contour, the mounting base can rotate around the center line of the circular contour under the action of the second power source, the cross-section of the flaring wheel is circular, the beveling wheel is at least its lower part is a conical surface that gradually narrows from top to bottom, and the longitudinal section of the flattening wheel is circular.

[0008] When flanging or flaring the upper end of the vertical cylinder, the cylinder needs to be positioned. Therefore, the flanging or flaring device also includes a positioning fixture for positioning the vertical cylinder. The vertical cylinder includes at least three side plates arranged sequentially along its circumference, with adjacent side plates connected by a corner transition. The positioning fixture includes:

[0009] A support platform is provided with multiple support components, which are spaced apart along a contour that is adapted to the cross-section of the bottom of the vertical cylinder.

[0010] The internal support assembly, when the vertical tube is placed on the support platform, allows the cross-section of the upper part of the vertical tube to coincide with an N-sided profile, where N≥3. The internal support assembly includes a drive mechanism and internal support members connected to the drive mechanism. Each of the internal support members can move outward toward the center of the N-sided profile or inward toward the center of the N-sided profile. The internal support members are used to press against the inner wall surface of the vertical tube.

[0011] The pressing assembly includes a second drive assembly and a pressing member connected to the second drive assembly and capable of moving up and down. The pressing member is used to press down on the top of the vertical cylinder.

[0012] An external pressure assembly, located on the outer periphery of an N-gonal contour, includes a first drive assembly and an external pressure member connected to the first drive assembly. The external pressure member can move toward or away from the N-gonal contour and is used to press against the outer wall surface of the vertical cylinder.

[0013] Before positioning the vertical cylinder, the inner support member of the inner support assembly is moved inward to its limit position, and the outer pressure member of the outer pressure assembly is moved outward to its limit position. This prevents interference with the inner support assembly and outer pressure assembly during the lowering process, which would hinder the smooth lowering. After the vertical cylinder is lowered, the lower pressure member of the lowering assembly is pressed down to press the vertical cylinder into place, with the upper end of the vertical cylinder above the inner support assembly and outer pressure assembly. Then, the inner support member of the inner support assembly is moved outward to its limit position to abut against the inner wall surface of the vertical cylinder, and the outer pressure member of the outer pressure assembly is moved towards the vertical cylinder to abut against the outer wall surface of the vertical cylinder. The outer pressure assembly and the inner support assembly work together to position the vertical cylinder. Then, the lower pressure member of the lowering assembly is removed, and the flange flaring mechanism performs the corresponding operation on the upper end of the vertical cylinder.

[0014] To facilitate the installation of the inner support assembly and the outer pressure assembly, the inner support is mounted on the support platform, and the outer pressure assembly is mounted on the platform. Both the support platform and the platform are located above the bearing platform, with the platform situated on the outer periphery of the support platform. A gap exists between them for the vertical cylinder to pass through. When the vertical cylinder is placed on the bearing platform, the support platform and the platform are adjacent to the top of the vertical cylinder. This positioning of the inner support assembly and the outer pressure assembly near the top of the vertical cylinder prevents deformation of the vertical cylinder during flange or flaring of the upper end, thus ensuring the accuracy of the flange or flaring.

[0015] In order to guide the movement trajectory of the inner support member, each inner support member and the support platform are provided with a first slide rail and a first slide groove that are in sliding fit. One end of the first slide rail faces the inside of the N-sided contour and the other end faces the outside of the N-sided contour.

[0016] In order to guide the movement trajectory of the external pressure component, each of the external pressure components and the platform is provided with a second slide rail and a second slide groove that are in sliding fit. One end of the second slide rail is facing the N-sided contour, and the other end is away from the N-sided contour.

[0017] The external pressure components include external pressure blocks, the same number as the corner portions, and external pressure strips, the same number as the side plates. Each external pressure block can press against the outer wall surface of a corner portion, and each external pressure strip can press against the outer wall surface of a side plate. The first driving assembly includes a first driving source, the same number as the external pressure components, with each first driving source driving one external pressure component.

[0018] To ensure the effective pressure of the external pressure components against the outer wall of the vertical cylinder, each set of external pressure components is equipped with a corresponding locking component. The locking component includes a third driving component and a locking member connected to the third driving component. The locking member is located outside the external pressure component, and the two can abut against each other. This allows the locking member to press against the external pressure component, preventing it from shifting outwards and affecting its pressure effect on the outer wall of the vertical cylinder.

[0019] The locking member can move toward or away from the external pressure member, or it can move up and down. The locking member has a seventh inclined surface that slopes inward from top to bottom, and the external pressure member has an eighth inclined surface that slopes inward from top to bottom. The seventh and eighth inclined surfaces can press against each other so that the locking member presses against the external pressure member.

[0020] To guide the vertical cylinder during lowering and ensure its proper placement, the support platform is equipped with guide posts for guiding the outer surface of the cylinder's bottom. The top wall of the guide posts slopes downwards towards the desired placement position of the cylinder. When the bottom of the cylinder contacts the top wall of the guide posts, the sloped surface guides the cylinder.

[0021] After the upper end of the upright cylinder is flanged or flared, the positioning fixture further includes a pushing assembly to facilitate its removal. This pushing assembly includes a fourth drive assembly and a pushing rod connected to the fourth drive assembly. The pushing rod extends vertically and can move up and down. With the upright cylinder placed on the support platform, the bottom of the upright cylinder is positioned along the upward movement path of the pushing rod. This allows the pushing rod to push the upright cylinder upwards, making it easier for the user to grasp the top of the upright cylinder and move it upwards from the positioning fixture.

[0022] When it is not necessary for the pressing member to press against the vertical cylinder, the pressing member needs to be moved away. If the pressing member is only moved upward, it will be located directly above the vertical cylinder, which may interfere with the flange flaring mechanism. Therefore, the pressing assembly also includes a vertically extending moving rod. The moving rod is connected to the second drive assembly and can move up and down. The pressing member is mounted on the moving rod and can rotate around it. When it is necessary for the pressing member to press down against the top of the vertical cylinder, the pressing member is first rotated to be directly above the vertical cylinder, and then the pressing member moves downward with the moving rod to the position where it presses down against the top of the vertical cylinder. When it is not necessary for the pressing member to press down against the top of the vertical cylinder, the pressing member is first moved upward with the moving rod to a position away from the top of the vertical cylinder, and then the pressing member is rotated to a position away from the top of the vertical cylinder.

[0023] To reduce the travel distance of the external pressure component, the positioning fixture further includes a side-push assembly. This side-push assembly includes a fifth drive assembly and a side-push plate connected to the fifth drive assembly. The side-push plate is mounted on a support platform and can move towards or away from the installation position of the vertical cylinder. At least one set of external pressure components is mounted on the side-push plate. When the external pressure component needs to press inward against the outer wall of the vertical cylinder, the side-push plate is moved inward first, and then the external pressure component is moved inward, thus minimizing the travel distance of the external pressure component.

[0024] The side push plate is set horizontally, and a third slide rail and a third slide groove are provided between the side push plate and the support platform for sliding cooperation. One end of the third slide rail faces the installation position of the vertical cylinder, and the other end is away from the installation position of the vertical cylinder. The third slide rail and the third slide groove cooperate to guide the movement trajectory of the side push plate.

[0025] The side push plate has a vertically positioned plate with a through hole. A vertically extending fixing plate is fixed on the support platform. The fixing plate has a knob that can rotate around a horizontally extending axis. When the vertical plate moves towards the installation position of the vertical cylinder to the fixing plate, the knob passes through the through hole. Rotating the knob makes it abut against the vertical plate. When it is necessary to reset the side push plate, rotating the knob makes it fully align with the through hole, thus allowing the side push plate to move. The through hole is an oblong hole extending horizontally.

[0026] To enhance the compressive effect of the internal support components on the interior of the vertical cylinder, the internal support components include internal support blocks (the same number as the side plates) and internal support strips (the same number as the corners). Multiple internal support strips are arranged sequentially along an N-sided profile that conforms to the upper cross-section of the vertical cylinder. An internal support block is positioned between every two adjacent internal support strips. Each internal support strip can move outwards towards the center of the N-sided profile or inwards towards the center of the N-sided profile. Similarly, each internal support block can move outwards towards the center of the N-sided profile or inwards towards the center of the N-sided profile. When all internal support strips and blocks are moved outwards to their extreme positions, each internal support strip is used to press against the inner wall surface of the side plates of the vertical cylinder, and each internal support block is used to press against the inner wall surface of the corners of the vertical cylinder. This ensures that the inner wall surfaces of the side plates and corners of the vertical cylinder are pressed outwards, providing comprehensive circumferential pressure and preventing localized deformation of the vertical cylinder.

[0027] Preferably, both end faces of the inner support strip along its length are first inclined surfaces, which slope towards the corresponding inner support block along the length of the inner support strip. The inclined surface of the inner support block adjacent to the first inclined surface is a second inclined surface, and the first and second inclined surfaces are inclined to fit together. In this way, the inner support block and the inner support strip are mutually pressed and positioned, reducing the risk of displacement.

[0028] The inner support member can be moved manually, but this is rather cumbersome. Therefore, preferably, the inner support assembly further includes a first drive mechanism connected to the inner support block and a second drive mechanism connected to the inner support bar.

[0029] In the above scheme, the first driving mechanism includes a first driving member with the same number as the number of inner support blocks, and each first driving member drives one inner support block.

[0030] In the above scheme, the second driving mechanism includes a second driving member, a driving block and a transmission structure. The driving block is connected to the second driving member and can move up and down. A transmission structure is provided between the driving block and the inner support bar to make the inner support bar move back and forth.

[0031] The transmission structure can have various structural forms. One such form is as follows: the transmission structure includes two connecting rods, the driving block is located between two opposing inner support bars, and the two inner support bars are rotatably connected to the first ends of the two connecting rods respectively. The second ends of the two connecting rods are rotatably connected to the driving block, and the rotation axes of the two ends of the connecting rods are perpendicular to the arrangement direction of the two opposing inner support bars.

[0032] The transmission structure can have various structural forms. Another structural form is as follows: the driving block is located inside the corresponding inner support bar. The inner wall surface of the inner support bar has a first vertical surface and a third inclined surface. The driving block has a second vertical surface and a fourth inclined surface. The third and fourth inclined surfaces are both inclined outward from top to bottom. The third and fourth inclined surfaces can press against each other, causing the inner support bar to move outward. When the inner support bar moves outward to its limit position, the second vertical surface of the driving block abuts against the first vertical surface of the inner support bar. Each inner support bar maintains the tendency to move inward under the action of the first elastic element. The third inclined surface, the fourth inclined surface, and the first elastic element together constitute the transmission structure.

[0033] The inner support bars and inner support blocks are collectively referred to as inner support components. While the inner support blocks and bars can be manually driven to move, this is cumbersome. Therefore, preferably, the inner support assembly also includes a drive source and a transmission mechanism. The transmission mechanism includes a transmission table and transmission components mounted on the transmission table. The transmission table is connected to the drive source and can move up and down. The number of transmission components is the same as the number of inner support components, and they are arranged in a one-to-one correspondence. A transmission component is provided between the transmission component and the corresponding inner support component to enable the inner support component to move back and forth. In this way, all inner support components can be moved by a single drive source, simplifying the structure. The drive source can be a motor, cylinder, etc.

[0034] The transmission assembly can have various structural forms. For example, each inner support member can be connected to the corresponding transmission member via a connecting rod. Alternatively, the transmission member can be located inside the corresponding inner support member. The inner wall of the inner support member has a third vertical surface and a fifth inclined surface. The transmission member has a fourth vertical surface and a sixth inclined surface. Both the fifth and sixth inclined surfaces are inclined outward from top to bottom. The fifth and sixth inclined surfaces can press against each other, causing the inner support member to move outward. When the inner support member moves outward to its limit position, the fourth vertical surface of the transmission member abuts against the third vertical surface of the inner support member. Under the action of the second elastic member, each inner support member maintains the tendency to move inward. The fifth and sixth inclined surfaces and the second elastic member together constitute the transmission assembly.

[0035] In the above scheme, the vertical tube has four side plates, and the N-sided profile is a quadrilateral profile.

[0036] The technical solution adopted by the present invention to solve the second technical problem mentioned above is as follows: a method for flanging and flaring the vertical cylinder of a cleaning machine tank, using the above-mentioned flanging and flaring device, wherein the flaring wheel, the beveling wheel, and the flattening wheel are collectively referred to as processing wheels, and the flanging and flaring method includes the following steps:

[0037] (1) In the initial state, the inner support components of the inner support assembly are all in the inner limit position, and the outer pressure components of the outer pressure assembly are all in the outer limit position. Then the vertical cylinder is placed on the bearing platform from top to bottom.

[0038] (2) The pressing component of the pressing assembly presses down, so that the vertical cylinder is pressed down into place, and the upper port of the vertical cylinder is located above the inner support assembly and the outer pressing assembly;

[0039] (3) The inner support component of the inner support assembly moves outward to abut against the inner wall surface of the vertical tube, and the outer pressure component of the outer pressure assembly moves towards the vertical tube to abut against the outer wall surface of the vertical tube;

[0040] (4) The pressing component of the pressing assembly is removed;

[0041] (5) Under the action of the second power source, the mounting base rotates until the corresponding processing wheel abuts against the inner wall surface of the upper end of the cylinder. Then the first power source drives the mounting base to rotate around the circumference of the upper end of the cylinder, and the processing wheel spins the top of the cylinder.

[0042] (6) After the operation of step (5) is completed, the inner support components of the inner support assembly are all moved to the inner limit position, and the outer pressure components of the outer pressure assembly are all moved to the outer limit position. The vertical cylinder is then removed.

[0043] In the above scheme, when flanging the upper end of the vertical tube, step (5) specifically includes the following two steps:

[0044] Step 1: Under the action of the second power source, the mounting base rotates until the corresponding bend wheel abuts against the inner wall surface of the upper port of the vertical cylinder. Then, the first power source drives the mounting base to rotate one revolution around the circumference of the upper port of the vertical cylinder. The bend wheel spins and presses the top of the vertical cylinder to form a folded edge with a set angle.

[0045] Step 2: Under the action of the second power source, the mounting base rotates until the rolling wheel is located on the inner wall of the upper end of the cylinder, and the rolling wheel presses against the folded edge. Then, the first power source drives the mounting base to rotate one revolution around the circumference of the upper end of the cylinder, so that the rolling wheel presses the folded edge downward to a horizontal state to form a flange.

[0046] In the above scheme, when flaring the upper end of the vertical tube, step (5) is as follows: the mounting base rotates under the action of the second power source until the corresponding flaring wheel abuts against the inner wall surface of the upper end of the vertical tube. Then the first power source drives the mounting base to rotate around the circumference of the upper end of the vertical tube, so that the flaring wheel presses the vertical tube outward to flare the upper end of the vertical tube. This is one process. This process is performed at least once until the flaring reaches the set size.

[0047] Compared with the prior art, the advantages of this invention are as follows: This invention integrates a flaring wheel, a beveling wheel, and a flattening wheel onto a single mounting base. The flaring wheel is used to flare the vertical cylinder, and the beveling wheel and flattening wheel are used to flanging the vertical cylinder. In this way, a single set of equipment can perform both flanging and flaring of the vertical cylinder, involving fewer parts and occupying less space. When the corresponding operation is required, the mounting base only needs to be rotated to rotate the required processing wheels (flaring wheel, beveling wheel, and flattening wheel) to the part of the vertical cylinder that needs to be processed. Then, the mounting base moves under the action of a first power source to spin and press the vertical cylinder. Compared with the existing method of changing equipment, the operation is more convenient. Attached Figure Description

[0072] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0073] In the description of this invention, it should be understood that, unless otherwise stated, "a plurality of" means two or more, and the terms "upper," "lower," "left," "right," "top," "bottom," "front," "rear," etc., indicate the orientation or positional relationship based on the direction or positional relationship shown in the drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0074] In the description of this invention patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an adhesive connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention patent based on the specific circumstances.

[0075] like Figure 1 As shown, the flange and flaring device of the vertical cylinder of the cleaning machine tank in this preferred embodiment includes a flange and flaring mechanism 9 and a positioning fixture.

[0076] like Figure 17 , 24 As shown, the vertical tube 1 includes at least three side plates arranged sequentially along its circumference. Adjacent side plates are connected by a corner transition. In this embodiment, there are four side plates, and the corners are arc-shaped.

[0077] like Figure 1 , 2 As shown, the flaring mechanism 9 includes a mounting base 91, a first power source, and a second power source. The mounting base 91 can move under the action of the first power source. The bottom of the mounting base 91 is provided with a flaring wheel 92, a beveling wheel 93, and a flattening wheel 94. The flaring wheel 92, the beveling wheel 93, and the flattening wheel 94 are evenly spaced along the same circular contour. The mounting base 91 can rotate around the center line of the circular contour under the action of the second power source. The cross-section of the flaring wheel 92 is circular, the beveling wheel 93 is at least its lower part a tapered surface that gradually narrows from top to bottom, and the longitudinal section of the flattening wheel 94 is circular. Both the first power source and the second power source can be a motor, a cylinder, a hydraulic cylinder, etc.

[0078] In this embodiment, both the flaring wheel 92 and the flattening wheel 94 are cylindrical. The axis of the flaring wheel 92 extends vertically, and the axis of the flattening wheel 94 extends horizontally. The lower part of the beveling wheel 93 has a tapered structure 931 that gradually narrows from top to bottom. The diameter of the flaring wheel 92 is determined according to the required flaring size of the vertical cylinder 1. The taper of the tapered structure 931 of the beveling wheel 93 is fixed according to the angle of the beveled edge that the vertical cylinder 1 needs to be tilted. The length of the flattening wheel 94 along its axis is determined by the width of the bevel that needs to be flattened.

[0079] The lowest points of the flaring wheel 92, the beveling wheel 93, and the flattening wheel 94 are located on the same horizontal plane to avoid interference between the other two machining wheels and the positioning fixture when one of the machining wheels is working. In addition, the flaring wheel 92, the beveling wheel 93, and the flattening wheel 94 are evenly spaced along the same circular contour to avoid interference between the other two machining wheels and the positioning fixture when one of the machining wheels is working.

[0080] This invention integrates a flaring wheel 92, a beveling wheel 93, and a flattening wheel 94 onto a single mounting base 91. The flaring wheel 92 flares the vertical cylinder 1, while the beveling wheel 93 and flattening wheel 94 flanging the vertical cylinder 1. This allows for both flanging and flaring of the vertical cylinder 1 with a single set of equipment, involving fewer components and requiring less space. When the corresponding operation is needed, the mounting base 91 simply rotates, positioning the required processing wheels (flaring wheel 92, beveling wheel 93, and flattening wheel 94) at the desired location on the vertical cylinder 1. Then, under the action of a first power source, the mounting base 91 moves to spin-press the vertical cylinder 1. Compared to existing methods that require changing equipment, this method is much more convenient. The mounting base 91 can be mounted on a support; as the support moves under the action of the first power source, the mounting base moves accordingly.

[0081] When the upper end of the vertical tube 1 is flanged or flared, the vertical tube 1 needs to be positioned. Therefore, a positioning fixture is required to position the vertical tube 1. The positioning fixture includes a bearing platform 2, an inner support assembly 3, a pressing assembly 4, an outer pressing assembly 5, a locking assembly 6, and a pushing assembly 7.

[0082] like Figure 5 As shown, the support platform 2 is provided with multiple support members 21. The outer wall surface of each support member 21 is a support surface 211 on which the bottom of the vertical cylinder 1 can rest. The support surface 211 is an inclined surface that slopes outward from top to bottom. The inclined surface can guide the vertical cylinder 1 when it is placed. There are multiple support members 21 and they are spaced apart along a contour that matches the bottom cross-section of the vertical cylinder 1.

[0083] In addition, the support platform 2 is provided with guide posts 22 for guiding the outer surface of the bottom of the vertical cylinder 1. The top wall surface of the guide posts 22 is inclined from top to bottom toward the position where the vertical cylinder 1 is to be placed. When the bottom of the vertical cylinder 1 contacts the top wall surface of the guide posts 22, the inclined surface will guide the vertical cylinder 1.

[0084] When the inner support assembly 3 is placed on the support platform 2, the cross-section of the upper part of the vertical cylinder 1 can coincide with an N-sided profile, where N≥3. In this embodiment, N is 4. The inner support assembly 3 includes a drive mechanism and an inner support member connected to the drive mechanism. The inner support member can move outward toward the center of the N-sided profile or inward toward the center of the N-sided profile. The inner support member is used to press against the inner wall surface of the vertical cylinder 1.

[0085] like Figure 12 , 13 As shown, the internal support components include internal support blocks 31 in the same number as the side plates and internal support strips 32 in the same number as the corners. Multiple internal support strips 32 are arranged sequentially along an N-sided contour. An internal support block 31 is positioned between every two adjacent internal support strips 32. Each internal support strip 32 can move outwards towards the center of the N-sided contour or inwards towards the center of the N-sided contour. Similarly, each internal support block 31 can move outwards towards the center of the N-sided contour or inwards towards the center of the N-sided contour. When both internal support strips 32 and internal support blocks 31 are moved outwards to their extreme positions, each internal support strip 32 is used to press against the inner wall surface of the side plates of the vertical cylinder 1, and each internal support block 31 is used to press against the inner wall surface of the corners of the vertical cylinder 1. In this way, the inner wall surfaces of the side plates and the inner wall surfaces of the corners of the vertical cylinder 1 are pressed outwards, i.e., all-around pressing is performed in the circumferential direction, preventing local deformation of the vertical cylinder 1.

[0086] In this embodiment, both end faces of the inner support bar 32 along its length are first inclined surfaces 321. These first inclined surfaces 321 are inclined towards the corresponding inner support block 31 along the length of the inner support bar 32. The inclined surface of the inner support block 31 adjacent to the first inclined surface 321 is a second inclined surface 311. The first inclined surface 321 and the second inclined surface 311 are inclined and fit together. In this way, the inner support block 31 and the inner support bar 32 are mutually pressed and positioned, reducing the risk of displacement. The outer wall surface of the inner support bar 32 is flat, and the outer wall surface of the inner support block 31 is adapted to the shape of the corner to better support the inner wall surface of the vertical cylinder 1.

[0087] External pressure component 5 is located on the outer periphery of the N-gonal profile, such as Figure 6 , 7 As shown in Figures 9 and 10, the external pressure assembly 5 includes a first drive assembly 51 and an external pressure member 52 connected to the first drive assembly 51. The external pressure member 52 can move toward or away from the N-gonal contour and is used to press against the outer wall surface of the vertical cylinder 1. The first drive assembly 51 includes a first drive source with the same number as the external pressure members 52, and each first drive source drives one external pressure member 52. The first drive source can be a motor, cylinder, etc.

[0088] The external pressure member 52 includes external pressure blocks in the same number as the corners and external pressure strips in the same number as the side plates. The external pressure blocks can press against the outer wall surface of the corners one by one, and the external pressure strips can press against the outer wall surface of the side plates one by one. The inner wall surface of the external pressure strip is flat, and the inner wall surface of the external pressure block is adapted to the shape of the corner to better support the outer wall surface of the vertical cylinder 1.

[0089] The inner support component is mounted on the support platform 33, and the outer periphery of the support platform 33 is the N-shaped deformation profile. The outer pressure component 52 is mounted on the platform 53. Both the support platform 33 and the platform 53 are located above the bearing platform 2. The platform 53 is located on the outer periphery of the support platform 33, and there is a gap between them for the vertical cylinder 1 to pass through. When the vertical cylinder 1 is placed on the bearing component 21, the support platform 33 and the platform 53 are adjacent to the top of the vertical cylinder 1. In this way, the inner support component 3 and the outer pressure component 5 position the position adjacent to the top of the vertical cylinder 1 to prevent the vertical cylinder 1 from deforming when the upper end of the vertical cylinder 1 is flanged or flared, which would affect the accuracy of the flanged or flared opening.

[0090] In order to guide the movement trajectory of the internal support member, such as Figures 13-16 As shown, each inner support member and the support platform 33 are provided with a first slide rail 341 and a first slide groove 342 that are in sliding engagement. One end of the first slide rail 341 faces the inside of the N-sided contour, and the other end faces the outside of the N-sided contour. In this embodiment, the first slide rail 341 is provided on the support platform 33.

[0091] In order to guide the movement trajectory of the external pressure component 52, such as Figure 9 As shown, each external pressure component 52 is provided with a second slide rail 54 and a second slide groove 55 that are in sliding fit with the platform 53. One end of each second slide rail 54 faces the N-sided contour, and the other end is away from the N-sided contour. In this embodiment, the second slide rail 54 is provided on the platform 53.

[0092] Each set of external pressure components 5 is equipped with a corresponding set of locking components 6, such as Figure 9 As shown, the locking assembly 6 includes a third drive assembly 61 and a locking member 62 connected to the third drive assembly 61. The locking member 62 is located outside the outer pressure member 52 and the two can abut against each other. In this way, the locking member 62 can press against the outer pressure member 52 to prevent the outer pressure member 52 from moving outward and affecting the pressing effect on the outer wall surface of the vertical cylinder 1.

[0093] In this embodiment, the locking member 62 can move up and down. The locking member 62 is provided with a seventh inclined surface 621 that slopes inward from top to bottom, and the outer pressure member 52 is provided with an eighth inclined surface 521 that slopes inward from top to bottom. The seventh inclined surface 621 and the eighth inclined surface 521 can press against each other so that the locking member 62 presses against the outer pressure member 52. The third drive assembly 61 can be a motor or a cylinder, etc.

[0094] like Figure 8 , 10As shown, the pressing assembly 4 includes a second drive assembly 41 and a pressing member 42 connected to the second drive assembly 41 and capable of moving up and down. The pressing member 42 is used to press down on the top of the vertical cylinder 1. The second drive assembly 41 can be a motor or a cylinder, etc.

[0095] When it is not necessary for the pressing member 42 to press against the vertical cylinder 1, the pressing member 42 needs to be moved away. If the pressing member 42 is only moved upward, it will be located directly above the vertical cylinder 1, and it is easy for it to interfere with the flange flaring mechanism 9. Therefore, the pressing assembly 4 also includes a vertically extending moving rod 43. The moving rod 43 is connected to the second drive assembly 41 and can move up and down. The pressing member 42 is mounted on the moving rod 43 and can rotate around the moving rod 43. When it is necessary for the pressing member 42 to press down against the top of the vertical cylinder 1, the pressing member 42 is first rotated to be directly above the vertical cylinder 1, and then the pressing member 42 moves downward with the moving rod 43 to the position where it presses down against the top of the vertical cylinder 1. When it is not necessary for the pressing member 42 to press down against the top of the vertical cylinder 1, the pressing member 42 is first moved upward with the moving rod 43 to a position away from the top of the vertical cylinder 1, and then the pressing member 42 is rotated to a position away from the top of the vertical cylinder 1.

[0096] After the upper end of the vertical cylinder 1 is flanged or flared, a jacking assembly 7 is installed to facilitate the removal of the vertical cylinder 1, such as... Figure 4 , 11 As shown, the jacking assembly 7 includes a fourth drive assembly 71 and a jacking rod 72 connected to the fourth drive assembly 71. The jacking rod 72 extends vertically and can move up and down. When the vertical cylinder 1 is placed on the support platform 2, the bottom of the vertical cylinder 1 is located on the upward movement path of the jacking rod 72. In this way, the vertical cylinder 1 can be pushed upward by the jacking rod 72, making it easier for the user to grasp the top of the vertical cylinder 1 and move it upward onto the self-positioning fixture. The fourth drive assembly 71 can be a motor or a cylinder.

[0097] In this embodiment, the fourth drive assembly 71 is connected to a plate 73, and there are multiple push rods 72 mounted on the plate 73.

[0098] The flanging and flaring method for the vertical cylinder 1 of the cleaning machine tank adopts the above-mentioned flanging and flaring device. The flaring wheel 92, the bend wheel 93, and the flattening wheel 94 are collectively referred to as processing wheels. The flanging and flaring method includes the following steps:

[0099] (1) In the initial state, the inner support members of the inner support assembly 3 are all in the inner limit position, and the outer pressure members 52 of the outer pressure assembly 5 are all in the outer limit position. At this time, the inner support members and the outer pressure members 52 will not interfere with the lowering of the vertical cylinder 1. Then, the vertical cylinder 1 is placed on the support platform 2 from top to bottom. During the lowering process of the vertical cylinder 1, the resting surface 211 of the support member 21 on the support platform 2 and the inclined surface on the guide column 22 will guide the vertical cylinder 1.

[0100] (2) The pressing part 42 of the pressing assembly 4 presses down, so that the vertical cylinder 1 is pressed down into place. The upper port of the vertical cylinder 1 is located above the inner support assembly 3 and the outer pressing assembly 5, so that the processing wheel can operate the upper port.

[0101] (3) The inner support component of the inner support assembly 3 moves outward to abut against the inner wall surface of the vertical cylinder 1, and the outer pressure component 52 of the outer pressure assembly 5 moves towards the vertical cylinder 1 to abut against the outer wall surface of the vertical cylinder 1. Then the locking component of the locking assembly abuts against the outer pressure component 52. At this time, the position of the vertical cylinder 1 near the top is pressed by the inner support assembly 3 and the outer pressure assembly 5 together, and it is not easy to deform.

[0102] (4) The pressing component 42 of the pressing assembly 4 is removed;

[0103] (5) Under the action of the second power source, the mounting base 91 rotates until the corresponding processing wheel abuts against the inner wall surface of the upper port of the vertical cylinder 1. Then the first power source drives the mounting base 91 to rotate around the circumference of the upper port of the vertical cylinder 1, and the processing wheel spins the top of the vertical cylinder 1.

[0104] (6) After the operation of step (5) is completed, the inner support members of the inner support assembly 3 are all moved to the inner limit position, the locking member of the locking assembly is released from the pressure of the outer pressure member 52, the outer pressure member 52 of the outer pressure assembly 5 are all moved to the outer limit position, the pushing assembly 7 pushes the vertical cylinder 1 up and removes the vertical cylinder 1.

[0105] When flanging the upper end of the vertical tube 1, step (5) specifically includes the following two steps:

[0106] Step 1: Under the action of the second power source, the mounting base 91 rotates until the corresponding beveling wheel 93 abuts against the inner wall surface of the upper port of the vertical cylinder 1. Then, the first power source drives the mounting base 91 to rotate one revolution around the circumference of the upper port of the vertical cylinder 1, and the beveling wheel 93 spins and presses the top of the vertical cylinder 1 to form a folded edge with a set angle. Figure 18 As shown, the inclination angle of fold a is 45°;

[0107] Step Two: Under the action of the second power source, the mounting base 91 rotates until the flattening roller 94 is located on the inner wall surface of the upper port of the vertical cylinder 1, and the flattening roller 94 presses against the folded edge a. Then, the first power source drives the mounting base 91 to rotate one revolution around the circumference of the upper port of the vertical cylinder 1, so that the flattening roller 94 presses the folded edge downward to a horizontal state (90°) to form the flange b. Figure 17 , 18 As shown;

[0108] The process of steps one and two above is as follows: Figure 18 As shown.

[0109] When flaring the upper end of the vertical cylinder 1, step (5) specifically involves: the mounting base 91 rotating under the action of the second power source until the corresponding flaring wheel 92 presses against the inner wall surface of the upper end of the vertical cylinder 1; then, the first power source drives the mounting base 91 to rotate one revolution around the circumference of the upper end of the vertical cylinder 1, causing the flaring wheel 92 to press the vertical cylinder 1 outward, thus flaring the upper end of the vertical cylinder 1. This constitutes one process, which is performed at least once until the flaring reaches the set size. The flared portion is as follows: Figure 24 As shown in the reference numeral c.

[0110] When flange or flare the upper end of the vertical cylinder 1, the inner support component 3 of the positioning fixture is different, mainly due to the different drive mechanism. The positioning fixture adapted for flange is called the flange positioning fixture, and the positioning fixture adapted for flaring is called the flaring positioning fixture.

[0111] For flange positioning fixtures:

[0112] The drive mechanism includes a first drive mechanism connected to the inner support block 31 and a second drive mechanism connected to the inner support bar 32.

[0113] In this embodiment, the first driving mechanism includes a number of first driving members that are the same as the number of inner support blocks 31, with each first driving member driving one inner support block 31. The first driving rods are motors, cylinders, etc.

[0114] The second drive mechanism includes a second drive component, a drive block 37, and a transmission structure. The drive block 37 is connected to the second drive component and can move up and down. A transmission structure is provided between the drive block 37 and the inner support bar 32, which allows the inner support bar 32 to move back and forth. The second drive component is a motor, cylinder, etc.

[0115] The first structural form of the transmission structure is as follows: Figure 14 As shown, the transmission structure includes two connecting rods 38, and a driving block 37 is located between two opposing inner support bars 32. Each inner support bar 32 is rotatably connected to the first end of one of the two connecting rods 38, and the second end of each connecting rod 38 is rotatably connected to the driving block 37. The rotation axes of the two ends of the connecting rods 38 are perpendicular to the arrangement direction of the two opposing inner support bars 32. When the driving block 37 moves upward, it drives the two connecting rods 38 to rotate, and the two inner support bars 32 move towards each other. When the driving block 37 moves downward, it drives the two connecting rods 38 to rotate, and the two inner support bars 32 move away from each other.

[0116] The second structural form of the transmission structure is as follows: Figure 15 , 16As shown, the drive block 37 is located inside the corresponding inner support bar 32. The inner wall surface of the inner support bar 32 has a first vertical surface 323 and a third inclined surface 322. The drive block 37 has a second vertical surface 371 and a fourth inclined surface 372. Both the third inclined surface 322 and the fourth inclined surface 372 are inclined outward from top to bottom. The third inclined surface 322 and the fourth inclined surface 372 can press against each other, causing the inner support bar 32 to move outward. When the inner support bar 32 moves outward to its limit position, the second vertical surface 371 of the drive block 37 abuts against the first vertical surface 323 of the inner support bar 32. Under the action of the first elastic element, each inner support bar 32 maintains the tendency to move inward. The third inclined surface 322, the fourth inclined surface 372, and the first elastic element (not shown in the figure) together constitute the transmission structure. The first elastic element can be a tension spring, with one end connected to the inner support bar 32 and the other end connected to the support platform 33.

[0117] During the upward movement of the drive block 37, the third inclined surface 322 and the fourth inclined surface 372 press against each other, causing the inner support bar 32 to move outward toward a position away from the center of the N-sided contour. When the second vertical surface 371 and the first vertical surface 323 abut against each other, the inner support bar 32 moves outward into position and is limited between the drive block 37 and the inner wall surface of the vertical cylinder 1. When the drive block 37 moves downward until the first vertical surface 323 and the second vertical surface 371 disengage, the limitation of the drive block 37 on the inner support bar 32 disappears, and the inner support bar 32 moves inward to reset under the action of the first elastic element.

[0118] In this embodiment, two opposing inner support bars 32 adopt the first structural form of the transmission structure, and these two inner support bars 32 share a common transmission structure; the other two opposing inner support bars 32 adopt the second structural form of the transmission structure, and these two inner support bars 32 are each configured with a corresponding transmission structure.

[0119] If the travel of the inner support bar 32 allows, there can be four inner support bars 32, with each pair of opposite inner support bars 32 adopting the first structural form of the transmission structure, or each inner support bar 32 adopting the second structural form of the transmission structure.

[0120] For flared positioning fixtures:

[0121] like Figures 21-23 As shown, the drive mechanism includes a drive source 39 and a transmission mechanism. The transmission mechanism includes a transmission platform 35 and transmission components 30 mounted on the transmission platform 35. The transmission platform 35 is connected to the drive source 39 and can move up and down. The number of transmission components 30 is the same as that of the inner support components, and they are arranged in a one-to-one correspondence. A transmission assembly is provided between the transmission component 30 and the corresponding inner support component to enable the inner support component to move back and forth. In this way, the movement of all inner support components can be realized through a single drive source 39, resulting in a simplified structure.

[0122] The transmission component 30 is located inside the corresponding inner support component. The inner wall surface of the inner support component has a third vertical surface 303 and a fifth inclined surface 304. The transmission component 30 has a fourth vertical surface 305 and a sixth inclined surface 306. The fifth inclined surface 304 and the sixth inclined surface 306 are both inclined outward from top to bottom. The fifth inclined surface 304 and the sixth inclined surface 306 can press against each other, causing the inner support component to move outward. When the inner support component moves outward to its limit position, the fourth vertical surface 305 of the transmission component 30 abuts against the third vertical surface 303 of the inner support component. Under the action of the second elastic element (not shown in the figure), each inner support component maintains the tendency to move inward. The fifth inclined surface 304, the sixth inclined surface 306, and the second elastic element together constitute the transmission assembly. The second elastic element can be a tension spring, with one end connected to the inner support component and the other end connected to the support platform 33.

[0123] As the transmission table 35 moves upward, the transmission component 30 moves upward accordingly. The fifth inclined surface 304 and the sixth inclined surface 306 press against each other, causing the inner support component to move outward toward a position away from the center of the N-sided contour. When the third vertical surface 303 and the fourth vertical surface 305 abut, the inner support component moves outward into position and is limited between the transmission table 35 and the inner wall surface of the vertical cylinder 1. When the transmission table 35 moves downward until the third vertical surface 303 and the fourth vertical surface 305 disengage, the limitation of the transmission table 35 on the inner support component disappears, and the inner support component moves inward to reset under the action of the second elastic component.

[0124] The reason why the drive mechanisms of the flange positioning fixture and the flaring positioning fixture have different structures is that the vertical cylinder 1 in this embodiment is not a straight vertical cylinder 1, such as... Figure 17 , 24 As shown, the vertical cylinder 1 includes a main body 11 and an expansion portion 12 protruding outward from one of the side walls of the main body 11. The main body 11 is a straight cylinder with the same or basically the same cross-sectional area from top to bottom, and the two ports of the vertical cylinder 1 have different diameters.

[0125] When performing flanging, the smaller opening faces down and the larger opening faces up, and flanging is performed at the larger opening. When performing flaring, the smaller opening faces up and the larger opening faces down, and flaring is performed at the smaller opening. Considering the different travel distances of the inner support component when performing flaring and flanging, different drive mechanisms are used, that is, different positioning fixtures are used.

[0126] If the existing straight cylindrical vertical tube 1 is adopted, such as the structure of the vertical tube 1 in CN217679451U in the background art, the positioning fixtures for both the flange and the flaring can be either flange positioning fixtures or flaring positioning fixtures.

[0127] Furthermore, because the vertical cylinder 1 of this application has an irregular shape, when the vertical cylinder 1 is placed for flaring, the external pressure component 5 on the flaring side will be far from the vertical cylinder 1 due to the flaring portion. In order to reduce the travel of the external pressure component 5 on the flaring side, such as Figure 19 As shown, the flaring positioning fixture also includes a side-push assembly 8. The side-push assembly 8 includes a fifth drive assembly and a side-push plate 81 connected to the fifth drive assembly. The side-push plate 81 is mounted on the support platform 2 and can move toward or away from the installation position of the vertical cylinder 1. At least one set of external pressure components 5 is provided on the side-push plate 81. The fifth drive assembly can be a motor or a cylinder. When the external pressure component 52 needs to press inward against the outer wall of the vertical cylinder 1, the side-push plate 81 is moved inward first, and then the external pressure component 52 is moved inward, thus reducing the travel distance of the external pressure component 52.

[0128] The side push plate 81 is horizontally set, and a third slide rail 82 and a third slide groove 83 are provided between the side push plate 81 and the support platform 2 for sliding cooperation. One end of the third slide rail 82 faces the installation position of the vertical cylinder 1, and the other end is away from the installation position of the vertical cylinder 1. The third slide rail 82 and the third slide groove 83 cooperate to guide the movement trajectory of the side push plate 81.

[0129] The side push plate 81 has a vertically arranged vertical plate 85 with a through hole 86. A vertically extending fixing plate 23 is fixedly mounted on the support platform 2. The fixing plate 23 has a knob 24 that can rotate around a horizontally extending axis. When the vertical plate 85 moves towards the installation position of the vertical cylinder 1 to the fixing plate 23, the knob 24 passes through the through hole 86. Rotating the knob 24 causes it to abut against the vertical plate 85. When it is necessary to reset the side push plate 81, rotating the knob 24 ensures it aligns perfectly with the through hole 86, thus allowing the side push plate 81 to move. The through hole 86 is an oblong hole extending horizontally.

[0130] If the vertical cylinder 1 is a regular straight cylinder with the same or basically the same cross-sectional area from top to bottom, then the side push assembly 8 may not be required. If the side push assembly 8 is provided, in step (3), before the external pressure member 52 on the side push plate 81 is activated, the side push plate 81 moves towards the installation position of the vertical cylinder 1. In step (6), before the external pressure member 52 on the side push plate 81 is activated, the side push plate 81 moves away from the installation position of the vertical cylinder 1.

[0131] In this article, "inner" refers to the direction closer to the center of the N-sided outline, and "outer" refers to the direction farther away from the center of the N-sided outline.

[0132] The flange and flaring device of the vertical cylinder of the cleaning machine tank can be controlled by a voice module. The module is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the flange and flaring device of the vertical cylinder of the cleaning machine tank to perform corresponding operations, thereby realizing intelligent control of the flange and flaring device of the vertical cylinder of the cleaning machine tank and improving the user experience.
