Description

Technical Field

[0001] The invention relates to the technical field of transformer core technology, in particular to an off-line assembly method for core side auxiliary parts. Background Art

[0002] The side parts of the core include upper clamps, lower clamps and multiple pull plates. In the conventional offline assembly of side parts, the relative height of the clamps and pull plates is basically adjusted manually. Especially for large side parts, the upper clamps and lower clamps are usually placed on the operating platform first, and the pull plates are placed on the clamps before adjusting the relative positions of the pull plates and clamps. The supporting positions of the clamps and pull plates are manually adjusted according to the size information of the clamps and pull plates on site. Most of the pull plate assembly requires manual handling and assembly, and there are no positioning measures during the assembly process, resulting in the need to continuously adjust the position during the assembly process to meet the assembly accuracy requirements. Such traditional offline assembly methods have the following problems:

[0003] First, during the assembly process, there are no length and width positioning measures for the clamps and pull plates, and the support position needs to be adjusted manually, which wastes a lot of time and affects the assembly efficiency;

[0004] Second, due to the different sizes of clamps and pull plates of different products, the height difference between the pull plate support and the clamp support needs to be adjusted. It is difficult to ensure the uniformity of the support height by adjusting most support seats, which requires a lot of adjustment and affects the assembly accuracy.

[0005] Third, most of the pull plate assembly requires manual handling and cooperation of multiple people, which greatly increases the workload of on-site personnel.

[0006] Fourth, after assembly, the side accessories of the core on the low-voltage side need to be hoisted and turned over for the assembly of the core, which is a large workload. Summary of the invention

[0067] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0068] Embodiment 1:

[0069] like Figure 1-Figure 5 , Fig.12 As shown, the core side auxiliary part 1 includes two clamps 12 arranged in parallel and at intervals, and the two clamps 12 are connected by a plurality of pull plates 11. The two clamps 12 are an upper clamp and a lower clamp, and usually the two have the same size. The core side auxiliary part is divided into a high-voltage side and a low-voltage side, and the two have the same structure. When assembling the two core side accessories, the two are arranged in parallel and oppositely, that is, the pull plates 11 face opposite directions, as shown in FIG. Fig.13 shown.

[0070] The present embodiment includes a lifting platform 3 arranged in the middle of the assembly platform 2, and a plurality of pull plate support seats 4 are arranged at intervals on the upper part of the lifting platform 3. The arrangement direction of the plurality of pull plate support seats 4 is a linear direction, and is the same as the arrangement direction of the plurality of pull plates 11. The assembly platforms 2 on both sides of the lifting platform 3 are respectively slidably installed with clamp support assemblies 5, and a grid assembly 6 is arranged on the assembly platform 2 outside each clamp support assembly 5. The length directions of the grid assembly 6 and the clamp support assembly 5 are consistent with the arrangement direction of the pull plate support seats 4. The overall height of the lifting platform 3 and the relative positions of the pull plate support seats 4 and the clamp support assemblies 5 are automatically adjusted by the control system.

[0071] The off-line assembly method of the core side auxiliary parts of this embodiment comprises the following steps:

[0072] S1: Determine the clamp width, clamp length, clamp thickness, clamp inner distance, pull plate thickness, pull plate width, pull plate spacing, and pull plate quantity, and input them into the control system.

[0073] S2: The upper part of the clamp support assembly 5 is the clamp support portion, which is used to support the clamp 12. The clamp support assembly 5 is moved to the side of the grid assembly 6, and ensures that the distance between the center line of the clamp support portion in the length direction and the grid assembly 6 is half of the clamp width. When the clamp 12 is placed on one side of the grid assembly 6, the side of the clamp 12 is fitted with the grid assembly 6 to ensure that the clamp 12 is placed in the center of the clamp support assembly 5, which is convenient for the subsequent operation and positioning of the moving clamp 12.

[0074] S3: Adjust the distance between the multiple pull-plate support seats 4 according to the pull-plate spacing value, so that the positioning centers of the multiple pull-plate support seats 4 are consistent with the positions of the multiple pull-plates 11. The line connecting the positioning centers of all the pull-plate support seats 4 is a symmetry line of the entire core side auxiliary member 1. The symmetry line of the core side auxiliary member 1 in the other direction passes through the positioning center of the pull-plate support seat 4 in the middle and is perpendicular to the above symmetry line. The line connecting the positioning centers of the pull-plate support seats 4 is a positioning reference in the assembly method of this embodiment.

[0075] S4: Adjust the overall height of the lifting platform 3 so that the pull plate supporting surfaces of the multiple pull plate support seats 4 and the clamp supporting parts of the clamp supporting assembly 5 maintain an initial height difference, and the initial height difference is used to ensure that the end of the pull plate 11 can be staggered with the clamp 12 up and down; the pull plate 11 and the clamp 12 are staggered up and down to facilitate the subsequent adjustment of the overall height of the lifting platform 3 so that the assembly surfaces of the pull plate 11 and the clamp 12 fit together. At the same time, there are two ways to stagger the end of the pull plate 11 with the clamp 12 up and down, one is that the pull plate 11 is above the clamp 12, and the other is that the pull plate 11 is below the clamp 12.

[0076] S5: Place the clamp 12 on the clamp support assembly 5, with the outer edge of the clamp 12 in contact with the fence assembly 6, and ensure that the clamp 12 is centered on the clamp support assembly 5 along the length direction, and the middle parts of the two clamps 12 correspond to the middle pull plate 11;

[0077] The pull plate 11 is placed on the pull plate support seat 4 , ensuring that the pull plate 11 is centered relative to the positioning center of the pull plate support seat 4 in both length and width directions.

[0078] The clamp 12 and the pull plate 11 can be placed by manually operating the sling; when placing the clamp 12, the grid assembly 6 is used as a reference ruler to ensure that the clamp 12 is placed in the center of the width direction of the clamp support assembly 5. The clamp 12 is placed in the center of the clamp support assembly 5 along the length direction, which can be adjusted manually or automatically.

[0079] S6: Both clamp support assemblies 5 move toward the pull plate support seat 4 so that the distance between the center line of the clamp 12 in the length direction and the center line of the pull plate 11 in the width direction is the assembly horizontal distance, and the assembly horizontal distance is half of the sum of the clamp width and the clamp inner distance; that is, the line connecting the positioning centers of the pull plate support seat 4 is used as a reference to determine the assembly position of the clamp 12.

[0080] S7: Adjust the overall height of the lifting platform 3 so that the assembly surfaces at both ends of the pull plate 11 are in contact with the two clamps 12; the contact between the assembly surfaces and the clamps 12 includes the contact between the plates and the alignment of the assembly holes.

[0081] Specifically, the height adjustment of the lifting platform 3 in step S7 is adjusted according to the relative upper and lower positions of the pull plate 11 and the clamp 12. When the core side auxiliary part 1 on the high-voltage side is assembled, the pull plate support surface is higher than the clamp support part, and the height difference is a clamp thickness; when the core side auxiliary part 1 on the low-voltage side is assembled, the pull plate support surface is lower than the clamp support part, and the height difference is a pull plate thickness, ensuring that the state of the core side auxiliary part 1 after assembly is the same as the placement state when the core is assembled, saving the time of flipping the core side auxiliary part 1. Fig.13 As shown, the lower part is the state where the core side auxiliary parts 1 on the high-voltage side are assembled, and the upper part is the state where the core side auxiliary parts 1 on the low-voltage side are assembled.

[0082] S8: Assemble the two clamps 12 and the plurality of pull plates 11 together. Usually, multiple joints are locked with fasteners by manual operation.

[0083] A pull plate support seat 4 and a clamp support assembly 5 with adjustable relative positions are provided to support the pull plate 11 and the clamp 12. The control system combines the parameter information of the core side auxiliary part 1 and automatically adjusts the relative distance between the pull plate support seat 4 and the clamp support assembly 5 based on the positioning center of the pull plate support seat 4 to determine the relative assembly position of the pull plate 11 and the clamp 12. The overall height of the lifting platform 3 is automatically adjusted to facilitate the assembly of the core side auxiliary parts 1 on the high-voltage side and the low-voltage side. After assembly, the posture of the core side auxiliary parts 1 is consistent with the subsequent core assembly posture, thereby realizing overall offline assembly in a single-person operation, solving the problem of assembly accuracy not meeting the requirements, reducing the workload of on-site workers, and improving the overall assembly efficiency of the core.

[0084] Embodiment 2:

[0085] On the basis of the first embodiment, the structure of the equipment in the assembly method is further optimized to make the method steps more convenient and accurate, further improve production efficiency and reduce labor intensity.

[0086] like Figure 6-Figure 7 As shown, it also includes a support seat adjustment mechanism 7, the structure of the support seat adjustment mechanism 7 is: including a pull plate support beam 70 fixedly installed on the lifting platform 3, a fixed seat 74 is fixedly installed in the middle of the length direction of the pull plate support beam 70, two sliding seats 73 are respectively arranged on the pull plate support beam 70 on both sides of the fixed seat 74, the sliding seats 73 are slidably installed on the upper part of the pull plate support beam 70, and the sliding seats 73 and the fixed seats 74 are both provided with pull plate support seats 4;

[0087] The first screw rod 711 and the second screw rod 721 are rotatably mounted on the pull plate support beam 70. The first screw rod 711 and the second screw rod 721 are parallel to each other. The first screw rod 711 and the second screw rod 721 are both positive and negative screw rods symmetrical about the fixed seat 74.

[0088] A first drive motor 71 is installed at one end of the pull plate support beam 70, and the first drive motor 71 is transmission-connected to the first sliding seat 73 on both sides of the fixed seat 74 through the first screw rod 711. A second drive motor 72 is installed at the other end of the pull plate support beam 70, and the second drive motor 72 is transmission-connected to the second sliding seat 73 on both sides of the fixed seat 74 through the second screw rod 721.

[0089] Then in S3: when adjusting the distance between the plurality of pull plate support seats 4 according to the pull plate spacing value, the control system starts the first drive motor 71 and the second drive motor 72 to adjust the relative distance between the plurality of pull plate support seats 4 according to the number of pull plates 11 and the pull plate spacing parameters.

[0090] The two motors drive the two forward and reverse screw rods respectively to drive the sliding seats 73 on both sides of the fixed seat 74 to move in the opposite direction, so as to realize the rapid and accurate automatic adjustment of the relative position of the pull plate support seat 4 based on the position of the fixed seat 74, thereby shortening the operation time of step S3.

[0091] like Figure 7-Figure 8 As shown, the structure of the sliding seat 73 is: it includes a block body 731, the upper part of the block body 731 is used to install the pull plate support seat 4, the lower part of the block body 731 is slidably connected with the pull plate support beam 70, the block body 731 is provided with an avoidance hole 733 and a connecting part 732, the connecting part 732 is provided with a threaded hole, and the avoidance hole 733 and the threaded hole correspond to the first screw rod 711 and the second screw rod 721.

[0092] When the sliding seat 73 is driven to slide by the first screw rod 711, the threaded hole is threadedly matched with the first screw rod 711, and the second screw rod 721 passes through the avoidance hole 733; when the sliding seat 73 is driven to slide by the second screw rod 721, the threaded hole is threadedly connected with the second screw rod 721, and the first screw rod 711 passes through the avoidance hole 733. The sliding seat 73 cooperates with the first screw rod 711 and the second screw rod 721 through the avoidance hole 733 and the threaded hole, thereby realizing the compact structure of the support seat adjustment mechanism 7 and saving installation space.

[0093] like Fig. 9 As shown, the structure of the pull plate support seat 4 is as follows: it includes a base 41, on which two parallel and symmetrical clamping plates 42 are slidably mounted, the sliding direction of the clamping plates 42 is perpendicular to the length direction of the pull plate 11, the symmetry center of the two clamping plates 42 is the positioning center of the pull plate support seat 4, the base 41 between the two clamping plates 42 is used to place the pull plate 11, and the two side edges of the pull plate 11 cooperate with the clamping plates 42;

[0094] A driver 43 is installed on the base 41 , and the driver 43 is transmission-connected with the two clamping plates 42 . The driver 43 is used to change the distance between the two clamping plates 42 to make it consistent with the width of the pull plate.

[0095] Specifically, the structure of the relative movement of the two clamping plates 42 can drive two parallel racks to move toward each other through the rotation of a gear. The relative movement of the clamping plates 42 is achieved by installing the clamping plates 42 on the racks. The driver 43 can be a motor connected to the gear transmission or a cylinder connected to a single rack transmission.

[0096] Then in S5: after placing the pull plate 11 on the pull plate support seat 4, start the driver 43 to make the two clamping plates 42 move relative to each other so that the distance from the positioning center of the pull plate support seat 4 is half of the width of the pull plate, ensuring that the width direction of the pull plate 11 is centered relative to the positioning center of the pull plate support seat 4.

[0097] In addition, the length direction of the pull plate 11 in S5 is centered relative to the pull plate support seat 4 and is preliminarily adjusted by manually pulling the pull plate 11 to ensure that the end of the pull plate 11 in step S4 can be staggered up and down with the clamp 12. Without increasing the number of operators, the equipment investment cost is reduced, and the optimal assembly equipment layout and assembly method step setting are achieved.

[0098] like Figure 5-Figure 7 As shown, the structure of the lifting platform 3 is as follows: it includes two scissor lifting frames 32 and a platform plate 31 installed on the assembly platform 2, the lower end of the scissor lifting frames 32 cooperates with the assembly platform 2, the sliding parts 33 at the lower ends of the scissor lifting frames 32 are arranged relatively, the upper ends of the two scissor lifting frames 32 are connected to the platform plate 31 at the same time, and the pull plate support seat 4 is installed on the platform plate 31;

[0099] It also includes a lifting motor 35 and a lifting screw 34 arranged on the assembly platform 2. The output end of the lifting motor 35 is connected to the sliding parts 33 at the lower ends of the two scissor lifting frames 32 through the lifting screw 34, driving the two sliding parts 33 to move in the opposite direction.

[0100] Specifically, the scissors lifting frame 32 lifts and lowers the platform plate 31 by changing the angle between the two crossed parts. The lifting screw rod 34 is a centrally symmetrical positive and negative screw rod. The middle part of the lifting screw rod 34 is connected to the lifting motor 35 through a worm gearbox. The sliding part 33 at the lower end of the scissors lifting frame 32 slides in the slide groove on the assembly platform 2. The other side of the lower end of the scissors lifting frame 32 is hingedly mounted on the assembly platform 2. The installation method of the upper end of the scissors lifting frame 32 and the platform plate 31 is similar. The structure of using a motor and a screw rod to drive the scissors lifting frame 32 to drive the platform plate 31 to rise and fall has low cost and high lifting accuracy, and is convenient for adjusting the height of the clamp 12 and the pull plate 12 in the thickness direction.

[0101] like Figure 2-Figure 3 As shown, a transmission screw 8 is rotatably mounted on the assembly platform 2 , a transmission motor is mounted in the middle of the assembly platform 2 , and the output end of the transmission motor is transmission-connected to the two clamp support assemblies 5 through the transmission screw 8 .

[0102] Then in S6: the movement of the clamp support assembly 5 is started by the transmission motor, and the two clamp support assemblies 5 move simultaneously and the distance from the pull plate support seat 4 is always the same, thereby improving the assembly efficiency and assembly accuracy.

[0103] like Figure 10-11As shown, the structure of the clamp support assembly 5 is as follows: it includes a clamp support beam 50 slidably mounted on the assembly platform 2, a fixed mounting seat 54 mounted in the middle of the clamp support beam 50, and a plurality of sliding mounting seats 53 slidably mounted on the clamp support beam 50, the sliding mounting seats 53 are symmetrically distributed on the clamp support beam 50 on both sides of the fixed mounting seat 54, and also includes two centering structures 56, the two centering structures 56 are symmetrically arranged at both ends of the clamp support beam 50 with respect to the fixed mounting seat 54, and the position of the fixed mounting seat 54 corresponds to the positioning center of the pull plate support seat 4 in the middle;

[0104] It also includes a third drive motor 51 installed at one end of the clamp support beam 50, the third drive motor 51 is connected to the two centering structures 56 through a third screw rod 511, the third screw rod 511 is a positive and negative screw rod symmetrical about the fixed mounting seat 54, and both ends of the clamp 12 cooperate with the centering structure 56;

[0107] Then in S5: after the clamp 12 is placed on the clamp support assembly 5, when the clamp 12 is placed on the clamp support assembly 5 in the center along the length direction, the third drive motor 51 is started to move the two centering structures 56 to each centering structure 56 until the distance from the fixed mounting seat 54 is half of the length of the clamp. At this time, the centering structure 56 contacts the end of the clamp 12, and the clamp 12 is placed on the clamp support assembly 5 in the center along the length direction, so as to realize the automatic positioning and clamping of the clamp 12. In step S7, when the assembly surfaces at both ends of the pull plate 11 are in contact with the two clamps 12, the positions of the two clamps 12 remain unchanged, and the position of the pull plate 11 relative to the clamp 12 is further adjusted manually to align the assembly holes at the assembly surface and the clamp 12 in the fitting position. Under the condition that the number of operators is not increased, manual adjustment is realized during the installation process to avoid rigid positioning deviation caused by equipment error, and also reduce the manufacturing cost of the assembly equipment.

A handle is installed on the rotating shaft 552 to facilitate the operator to manually rotate the rotating shaft 552 and then adjust the angle of the support 553 to avoid other structures on the clamp 12.

[0110] like Fig.10 As shown, it also includes a fourth drive motor 52 installed at the other end of the clamp support beam 50. The fourth drive motor 52 is transmission-connected to the first sliding mounting seat 53 on both sides of the fixed mounting seat 54 through a fourth screw rod 521. The fourth screw rod 521 is a positive and negative screw rod symmetrical about the fixed mounting seat 54.

[0111] The control system drives the synchronous movement of the first sliding mounting seat 53 on both sides of the fixed mounting seat 54 through the motor and screw structure according to the input clamp length size, thereby realizing the positioning of the clamp support seat 55, reducing the workload of manually adjusting the distance between the clamp support seats 55, and ensuring the overall supporting effect of the clamp support assembly 5. At the same time, the position of the clamp support seat 55 can be flexibly selected by manually sliding the other two sliding mounting seats 53.
