The head is the end cover on the pressure vessel, which is a major pressure-bearing component of the pressure vessel and plays a sealing role.

During the turning process, since aluminum is relatively soft and there is no special auxiliary support device, the machining process can easily cause the aluminum heads to deform.

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 12As shown, a head finishing auxiliary support tooling described in an embodiment of the present invention comprises a bottom plate 1 and an annular plate 11; a group of connecting plates 12 are fixedly connected to the bottom plate 1, and the group of connecting plates 12 are evenly distributed in an annular shape, and the bottom end of the annular plate 11 is fixedly connected to the top end of the group of connecting plates 12; a group of first supporting plates 13 and a group of second supporting plates 14 are fixedly connected to the bottom plate 1, and the group of first supporting plates 13 and the group of second supporting plates 14 are both distributed in an annular shape, and the two are staggered, and the first supporting plates 13 and the second supporting plates 14 are the same size; the first supporting plates 13 and the second supporting plates 14 are both provided with a first arc surface 15 at the top; the top view of the connecting plate 12 is an isosceles trapezoid, and the connecting plate 1 2 is fixedly connected to the outer wall of the first hydraulic cylinder 16; the first hydraulic rod 17 is provided at the conveying end of the first hydraulic cylinder 16; a pressing rod 18 is provided at the top of the first hydraulic rod 17; a first through hole is provided at the position of the annular plate 11 relative to the pressing rod 18; the top of the pressing rod 18 passes through the first through hole and is provided with a pressing plate 19; a first groove 2 is provided on the first arc surface 15; a support block 21 is slidably connected in the first groove 2, and the top surface of the support block 21 is arc-shaped, and the top surface of the support block 21 and the first arc surface 15 are parallel to each other, and a group of rollers 22 are provided at the top of the support block 21, and the group of rollers 22 are distributed in an arc shape; the support block 21 moves up and down through the lifting member;In the prior art, large aluminum heads need to be finely processed. During the turning process, since aluminum is relatively soft and there is no special auxiliary support device, the processing process may easily cause the aluminum heads to deform. At the same time, the large aluminum heads themselves are also prone to unstable fixation, resulting in large processing quality errors such as turning, which greatly affects the product quality. For this reason, the present invention sets an auxiliary support tooling when working. When working, the large aluminum head is placed in the annular plate 11 through a lifting and hoisting device (not described in the prior art), so that the bottom end of the head and the first support block 21 are in contact with the first arc surface 15, and supported by the lifting member. At the same time, the side wall of the head opening is attached to the inner wall of the annular plate 11. Because it is initially placed, it is difficult for the top surface of the head opening to be in a horizontal state at this time. Therefore, the first hydraulic cylinder 16 is started at this time to move the first hydraulic rod 17 downward. At this time, the downward movement of the first hydraulic rod 17 will drive the lower pressure rod 18 and the lower pressure plate 19 to move downward, so that the lower pressure plate 19 is attached to the top surface of the head opening. Because of a group of evenly distributed The lower pressing plate 19 moves downward at the same time. The roller 22 on the support block 21 can be used to adjust the head, so that the top opening of the head is in a horizontal state. At the same time, the pressure sensor in the lower pressing plate 19 measures that the pressure is in the same rated range. At the same time, after the lower pressing plate 19 is pressed downward, it moves downward through the lifting member and the first hydraulic cylinder 16, and the support block 21 enters the first groove 2 as a whole, so that the bottom end of the head is attached to the first arc surface 15. At the same time, due to the downward movement of the first hydraulic cylinder 16, it can be ensured that the lower pressing plate 19 drives the head to move vertically downward to ensure the horizontal state of the head, thereby ensuring the accurate placement and positioning of the head. At the same time, when the interior of the head is finely processed, due to the downward pressure of the lower pressing plate 19, its stability can be effectively maintained. The uniform support force of the annular plate 11, the first support plate 13 and the second support plate 14 can effectively avoid the processing deformation of the aluminum head. At the same time, the lower pressing plate 19 is stably pressed to ensure the stability of subsequent processing, further ensuring that the processing error is within the rated range, and ensuring the processing quality. ;

[0037] The lifting member includes a second hydraulic cylinder 23 and a third hydraulic cylinder 24; the second hydraulic cylinder 23 and the third hydraulic cylinder 24 are respectively fixedly connected to the side walls of the first support plate 13 and the second support plate 14, and the second hydraulic cylinder 23 is located at the high part of the first arc surface 15, and the third hydraulic cylinder 24 is located at the low part of the first arc surface 15; the first through groove 25 and the second through groove 26 are respectively opened on the side walls of the first groove 2, and the first through groove 25 and the second through groove 26 correspond to the positions of the second hydraulic cylinder 23 and the third hydraulic cylinder 24 respectively; the connecting blocks 27 are fixedly connected to the side walls of the support block 21, and the same support block 21 has a plurality of connecting blocks 27 on each side. The two connecting blocks 27 are respectively slidably connected in the first through groove 25 and the second through groove 26; the output ends of the second hydraulic cylinder 23 and the third hydraulic cylinder 24 are respectively fixedly connected to the connecting blocks 27 on the adjacent sides; a pressure sensor is provided in the lower pressing plate 19; during operation, the supporting force of the second hydraulic cylinder 23 and the third hydraulic cylinder 24 is used to support the head in the initial state (initial release state), and then the rotation of the roller 22 can effectively adjust the horizontality of the head by pressing down the lower pressing plate 19, and at the same time, the support block 21 is supported by the second hydraulic cylinder 23 and the third hydraulic cylinder 24 to ensure the uniformity of the supporting force. When the lower pressing plate 19 is in the state of flattening the head, the pressure of the pressure sensor in the lower pressing plate 19 is basically within the same rated range. At this time, in order to further ensure stability, the support block 21 is retracted into the first groove 2 through the second hydraulic cylinder 23 and the third hydraulic cylinder 24, so that the bottom end of the head is attached to the first arc surface 15, and the lower pressing plate 19 will continue to press down to ensure the stability of the attachment level of the head.

[0038] The first hydraulic rod 17 and the lower pressure rod 18 are rotatably connected; a track groove 3 is provided on the outer wall of the lower pressure rod 18; the track groove 3 is composed of a first vertical groove 31, an arc groove 33 and a second vertical groove 32; the angle of the arc groove 33 is 180 degrees, and the first vertical groove 31 is located at the top of the arc groove 33, and the second vertical groove 32 is located at the bottom of the arc groove 33, and the first vertical groove 31, the arc groove 33 and the second vertical groove 32 are interconnected; a plurality of guide posts 34 are fixedly connected to the outer wall of the connecting plate 12, and each guide post 34 is slidably connected to the adjacent track groove 3; when working, if the lower pressure plate 19 is in the initial state, If the lower pressure plate 19 is oriented toward the center of the annular plate 11, it will be inconvenient to put the head into the annular plate 11. Therefore, the lower pressure plate 19 is initially away from the center of the annular plate 11, which will not affect the initial placement of the head. Then, when the first hydraulic rod 17 moves downward, the lower pressure rod 18 moves downward, and the guide column 34 passes through the second vertical groove 32 into the arc groove 33 and then into the first vertical groove 31. This process will allow the lower pressure rod 18 to rotate 180°, just enough to allow the lower pressure plate 19 to face the center of the annular plate 11 again, and then allow the guide column 34 to slide along the first vertical groove 31, thereby allowing the lower pressure rod 18 to move vertically downward, thereby ensuring the verticality of the downward pressure of the lower pressure plate 19.

[0039] The lower pressure rod 18 is composed of a first connecting rod 4 and a square rod 42; the bottom end of the first connecting rod 4 is rotatably connected to the top end of the first hydraulic rod 17, and the track groove 3 is located on the outer side wall of the first connecting rod 4; a square groove 41 is provided at the top end of the first connecting rod 4; a square rod 42 is slidably connected in the square groove 41, and the top end of the square rod 42 passes through the first through hole and is connected to the lower pressure plate 19; the square rod 42 is installed on the first connecting rod 4 through a disassembly part; a group of positioning parts are provided on the annular plate 11; when working, the inner part of the head is precisely adjusted. During processing, the downward pressure of the lower pressure plate 19 can generally be used for stabilization. However, when turning the outer side wall of the head opening, the lower pressure plate 19 and the lower pressure rod 18 will have an impact. Therefore, when processing the outer side wall of the head opening, a group of first hydraulic rods 17 are moved up in sequence. During the upward movement of the first hydraulic rods 17, the outer side wall of the head opening will be limited and fixed by the positioning parts. At the same time, after the positioning parts limit the head, the square rod 42 is manually removed from the first connecting rod 4 through the disassembly parts, thereby ensuring the processing of the outer side wall of the head opening.

[0040] The disassembly member includes a positioning groove 43; positioning grooves 43 are provided on both side walls of the square groove 41; a first cavity 44 is provided in the square rod 42, and through grooves 47 are provided on both sides of the first cavity 44; a pair of symmetrically distributed right-angled trapezoidal blocks 45 are slidably connected in the first cavity 44, and the sides of the pair of right-angled trapezoidal blocks 45 away from each other are fixed to the side wall of the first cavity 44 by springs, and the inclined surfaces of the pair of right-angled trapezoidal blocks 45 are arranged oppositely; the sides of the pair of right-angled trapezoidal blocks 45 away from each other are fixed with isosceles trapezoidal blocks 46, and the isosceles trapezoidal blocks 46 extend out through the through groove 47; a first threaded rod 49 is rotatably connected to the middle part of the bottom end of the first cavity 44, and the top end of the first threaded rod 49 passes through the square rod 42; a sliding rod 48 is provided in the first cavity 44, The sliding rod 48 is threadedly connected to the first threaded rod 49, and the two ends of the sliding rod 48 are respectively slidably connected to the inclined surfaces of a pair of right-angled trapezoidal blocks 45; during operation, when disassembly is required, the first threaded rod 49 is manually rotated to move the sliding rod 48 upward, thereby allowing a group of right-angled trapezoidal blocks 45 to move toward each other, allowing the isosceles trapezoidal blocks 46 to disengage from the positioning groove 43, releasing the fixation of the square rod 42, and then disassembling the square rod 42. At the same time, when the head needs to be initially placed later, the square rod 42 is placed in the square groove 41, and then the first threaded rod 49 is rotated to move the sliding rod 48 downward, thereby allowing a group of right-angled trapezoidal blocks 45 to move in the opposite direction, allowing the isosceles trapezoidal blocks 46 to snap into the positioning groove 43, that is, completing the installation of the square rod 42. At the same time, the isosceles trapezoidal blocks 46 are arranged to snap into the positioning groove 43 to avoid looseness.

[0041] The positioning member includes a fixing block 5; a group of fixing blocks 5 are fixedly connected to the annular plate 11, and a threaded through groove 51 is opened in the fixing block 5; a positioning threaded rod 52 is threadedly connected to the threaded through groove 51; the positioning threaded rod 52 is rotated by a power unit; during operation, when the first hydraulic rod 17 moves upward, the positioning threaded rod 52 is driven to rotate by the power unit, and then the positioning threaded rod 52 moves toward the center of the annular plate 11, and then rests on the outer side wall of the head placed flatly, that is, to ensure the horizontal stability of the head after the square rod 42 is disassembled.

[0042] The power unit includes a first gear 6; a first gear 6 is rotatably connected to the side wall of the fixed block 5; a pair of symmetrically distributed first slide grooves 62 are provided on the positioning threaded rod 52; a pair of symmetrically distributed first sliders 61 are fixedly connected to the inner wall of the first gear 6, and the first sliders 61 are slidably connected in the first slide grooves 62; a group of second grooves are provided in the annular plate 11; the side wall of the second groove and the first through hole are connected to each other; a second gear 63 is rotatably connected in the second groove through a rotating shaft; the top end of the second gear 63 extends out of the second groove and meshes with the first gear 6; an annular cylinder 64 is sleeved on the outer wall of the first connecting rod 4, and the outer plate of the annular cylinder 64 is strongly clamped by the outer plate of the annular cylinder 64. The spring 68 is fixed to the bottom end of the annular plate 11; a pair of symmetrically distributed second slide grooves 67 are provided in the annular tube 64; a rotating ring 65 is rotatably connected to the outer side wall of the top end of the first connecting rod 4, and a pair of symmetrically distributed second sliders 66 are fixed to the outer side wall of the rotating ring 65, and the pair of second sliders 66 are respectively slidably connected to the second slide grooves 67 on the adjacent sides; a guide groove 69 is provided in the first through hole; a guide block 691 is fixed to the outer side wall of the annular tube 64, and the guide block 691 is slidably connected to the guide groove 69; a group of teeth 692 is fixed to the outer side wall of the annular tube 64, and the group of teeth 692 meshes with the second gear 63; the inner diameter of the second gear 63 is larger than that of the second gear 63. When working, when it is necessary to process the outer wall of the head opening, the first hydraulic cylinder 16 is started in sequence, the first hydraulic rod 17 is moved up, and the guide column 34 passes through the second vertical groove 32, the arc groove 33, and slides into the first vertical groove 31. At this time, the lower pressure plate 19 is in the initial state, and it is reversed toward the center of the annular plate 11. Then the first hydraulic rod 17 continues to move up, thereby driving the first connecting rod 4 to move up, allowing the guide column 34 to slide in the first vertical groove 31, and at the same time, the second slider 66 on the rotating ring 65 is attached to the top of the second slide groove 67. At this time, the upward movement of the first connecting rod 4 will drive the annular cylinder 64 to move up, and the upward movement of the annular cylinder 64 will compress the strong spring 68. At the same time, due to a group of teeth 692 and the first The meshing of the two gears 63 drives the second gear 63 to rotate, and because the first gear 6 and the second gear 63 are meshed with each other, the first gear 6 is driven to rotate. The rotation of the first gear 6 drives the positioning threaded rod 52 to rotate in the threaded groove 51, so that the positioning threaded rod 52 moves toward the center of the annular plate 11 until the positioning threaded rod 52 rests on the outer wall of the head. At this time, the first hydraulic rod 17 has finished moving up, and the square rod 42 at this position can be removed, and then the next first hydraulic cylinder 16 can be started in sequence; wherein the first hydraulic rod 17 on the first hydraulic cylinder 16 is started in sequence to ensure the stable positioning of the positioning threaded rod 52, and also to avoid the instability of the head caused by the simultaneous disengagement of a group of first hydraulic cylinders 16.

[0044] The first support plate 13 is located on the side wall of the second hydraulic cylinder 23, and is slidably connected with the first rack 8 and the second rack 81, and a third gear 84 is provided in the middle of the first rack 8 and the second rack 81, and the third gear 84 is rotatably connected to the side wall of the first support plate 13; the first rack 8 and the second rack 81 are respectively meshed with the third gear 84; the end of the second rack 81 is fixedly connected to the first stop column 82; the side wall of the first rack 8 is fixedly connected to the first push plate 83, and the first push plate 83 is located in the space formed by the connecting block 27 and the hydraulic rod of the second hydraulic cylinder 23; the side of the first support plate 13 A first baffle is fixedly connected to the wall, and the first baffle and the second rack 81 are connected by a spring; the second support plate 14 is located on the side wall of the third hydraulic cylinder 24 and is slidably connected to the third rack 85 and the fourth rack 86, and a fourth gear 87 is provided in the middle of the third rack 85 and the fourth rack 86, and the fourth gear 87 is rotatably connected to the side wall of the second support plate 14; the third rack 85 and the fourth rack 86 are respectively meshed with the fourth gear 87; a second stop column 88 is fixedly connected to the fourth rack 86; a second push plate 89 is fixedly connected to the side wall of the third rack 85, and the second push plate 89 is located at the connection The space formed by the hydraulic rod of the block 27 and the third hydraulic cylinder 24; a second baffle is fixedly connected to the side wall of the second support plate 14, and the second baffle and the fourth rack 86 are connected by a spring; when working, when the lower pressure plate 19 is pressed down to stabilize, the effects of the first and second columns 82 and 88 are basically negligible, but after the lower pressure plate 19 is disassembled, when it is fixed by the positioning threaded rod 52, the first and second columns 82 and 88 can effectively increase the stability. At the same time, in actual work, when the support block 21 is retracted into the first groove 2 by the second hydraulic cylinder 23 and the third hydraulic cylinder 24, at this time The connecting block 27 cannot yet contact the first push plate 83 or the second push plate 89. Only after the support block 21 completely enters the first groove 2, the second hydraulic cylinder 23 and the third hydraulic cylinder 24 will continue to move the connecting block 27, thereby pushing the first push plate 83 or the second push plate 89, and through the first rack 8, the second rack 81 and the third gear 84 and the third gear 84, the fourth rack 86 and the fourth gear 87, the first support column 82 and the second support column 88 limit the bottom end of the head. At the same time, due to the different positions of the first support column 82 and the second support column 88, the stability of the head can be further effectively increased.

[0045] An operating method of a head finishing auxiliary support tooling, the operating method is applicable to the above-mentioned head finishing auxiliary support tooling, the method is as follows:

[0046] S1: Put the end cap through the middle of the annular plate 11, so that the bottom end of the end cap and the roller 22 on the support block 21 are in contact with each other, and then the first hydraulic cylinder 16 drives the lower pressing plate 19 to press down, and at the same time, the lower pressing plate 19 presses down to adjust the end cap to ensure that the initial end cap is placed horizontally;

[0047] S2: Then, the entire end cap is driven downward by the lifting member and the first hydraulic cylinder 16, so that the bottom surface of the end cap and the first arc surface 15 are in contact with each other, and then the interior of the end cap is finely processed;

[0048] S3: When the outer side wall of the head opening needs to be fine-machined, the square plate is disassembled by the disassembly parts, and the positioning parts are used to limit the head, and then the outer side wall of the head opening is fine-machined.

[0049] Working principle: Place the large aluminum end cap in the annular plate 11 through a lifting device (the prior art is not described), so that the bottom end of the end cap and the first support block 21 are in contact with the first arc surface 15, supported by the lifting member, and the side wall of the end cap opening is attached to the inner wall of the annular plate 11. Because it is a preliminary placement, it is difficult for the top surface of the end cap opening to be in a horizontal state. Therefore, the first hydraulic cylinder 16 is started at this time to move the first hydraulic rod 17 downward. At this time, the downward movement of the first hydraulic rod 17 will drive the lower pressure rod 18 and the lower pressure plate 19 to move downward, so that the lower pressure plate 1 9 is attached to the top surface of the head opening, and because a group of evenly distributed lower pressure plates 19 are moved downward at the same time, the head can be adjusted by using the roller 22 on the support block 21, so that the opening at the top of the head is in a horizontal state. At the same time, when the pressure sensor in the lower pressure plate 19 measures that the pressure is in the same rated range, the lifting member and the first hydraulic cylinder 16 are moved downward, and the support block 21 enters the first groove 2 as a whole, so that the bottom end of the head is attached to the first curved surface 15. At the same time, due to the downward movement of the first hydraulic cylinder 16, it can be ensured that the lower pressure plate 19 drives The head is moved down vertically to ensure the horizontal state of the head, thereby ensuring the accurate placement and positioning of the head. At the same time, when the interior of the head is finely processed, the downward pressure of the lower pressure plate 19 can effectively maintain its stability. The uniform support force of the auxiliary tooling through the annular plate 11, the first support plate 13 and the second support plate 14 can effectively avoid the processing deformation of the aluminum head. At the same time, the lower pressure plate 19 is stably pressed to ensure the stability of subsequent processing, further ensure that the processing error is within the rated range, and ensure the processing quality; when the interior of the head is finely processed, it can generally be The downward pressure of the lower pressure plate 19 is used for stabilization. However, when turning the outer side wall of the head opening, the lower pressure plate 19 and the lower pressure rod 18 will have an impact. Therefore, when processing the outer side wall of the head opening, a group of first hydraulic rods 17 are moved up in sequence. During the upward movement of the first hydraulic rods 17, the outer side wall of the head opening is limited and fixed by the positioning member. At the same time, after the positioning member limits the head, the square rod 42 is manually disassembled from the first connecting rod 4 through the disassembly member, thereby ensuring the processing of the outer side wall of the head opening;When it is necessary to process the outer wall of the head opening, the first hydraulic cylinder 16 is started in sequence to move the first hydraulic rod 17 upward, so that the guide column 34 passes through the second vertical groove 32, the arc groove 33, and slides into the first vertical groove 31. At this time, the lower pressure plate 19 is in the initial state, facing the center of the annular plate 11 in the opposite direction, and then the first hydraulic rod 17 continues to move upward, thereby driving the first connecting rod 4 to move upward, allowing the guide column 34 to slide in the first vertical groove 31, and at the same time, the second slider 66 on the rotating ring 65 is attached to the top of the second slide groove 67. At this time, the upward movement of the first connecting rod 4 will drive the annular cylinder 64 to move upward, and the upward movement of the annular cylinder 64 will compress the strong spring 68. At the same time, due to a set of teeth 692 and the second gear 63 The meshing of the first gear 6 and the second gear 63 drives the second gear 63 to rotate. The meshing of the first gear 6 and the second gear 63 drives the first gear 6 to rotate. The rotation of the first gear 6 drives the positioning threaded rod 52 to rotate in the threaded groove 51, so that the positioning threaded rod 52 moves toward the center of the annular plate 11 until the positioning threaded rod 52 abuts against the outer wall of the head. At this time, the first hydraulic rod 17 moves upward, and the square rod 42 at this position can be disassembled, and then the next first hydraulic cylinder 16 is started in sequence; wherein the first hydraulic rod 17 on the first hydraulic cylinder 16 is started in sequence to ensure the stable positioning of the positioning threaded rod 52, and to avoid the instability of the head caused by the simultaneous disengagement of a group of first hydraulic cylinders 16. ;
