Description

Technical Field

[0001] The present invention relates to the technical field of oil-conducting cavities, and in particular to automated processing equipment for oil-conducting cavities. Background Art

[0002] Oil guide cavity ( Figure 12 ) is an important component in the cooling structure of oil-immersed transformers and is of great significance to improving the cooling effect and operation reliability of transformers.

[0003] The oil-conducting cavity, located at the bottom of the transformer body and thought of as an insulated end ring with a housing, features decoupling notches at the four corners to facilitate unhooking during coil assembly. During installation, transformer oil enters through two openings in the upper cavity and is evenly distributed into the coil through small circular holes between the steps. After coil assembly, the cover and spacers are installed and sealed with glue. The outer edges are then screwed in place. Ensure the bottom end ring of the coil is flat to prevent bulging of the cardboard from hindering cover assembly. This significant feature ensures precise control of the oil flow rate and velocity into the windings by optimally managing the oil flow into the transformer body, preventing electrification caused by excessive oil flow. At low oil flow rates, this ensures optimal oil flow distribution among the windings, effectively eliminating dead zones and dead spots in horizontal oil channels. This improves coil heat dissipation, reduces average coil temperature rise, and prevents localized overheating or even burnout, ensuring stable transformer operation, extending its service life, and enhancing product quality and efficiency.

[0004] The oil guide cavity is processed from a laminate (multi-layer insulating cardboard), and there are multiple radially distributed protrusions in the oil guide cavity. The multiple protrusions are used to separate the wiring harness and support the cover. The processing of the oil guide cavity is generally integral milling. The blank is first fixed on the fixed seat, and then the outline of the protrusion is milled on the blank. After milling the side of a row of protrusions, the fixed seat is rotated so that the milling machine can mill the side of the other side of the row of protrusions. However, there is a certain error in the rotation angle of the fixed seat, and in the process of continuous multiple rotations, the error of the rotation angle of the fixed seat is constantly accumulating, and eventually affecting the milling accuracy of the blank, resulting in the angle between the final milled row of protrusions and the initially milled row of protrusions being quite different from the design angle, thereby affecting subsequent use. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic processing device for an oil guide cavity, aiming to solve the above problems.

[0009] The guide sleeve reciprocates along the first transverse groove to enable the guide cylinder to reciprocate along the first inclined groove or the second inclined groove in sequence and push the clamping disk to rotate relative to the guide cylinder.

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figure 1-12 As shown, an automatic processing device for an oil-conducting cavity includes a workbench 1, on which are provided:

[0038] The guide groove 12 includes a first transverse groove 121, a first oblique groove 125 and a second oblique groove 126 that are connected to the tail end of the first transverse groove 121 and have different inclination angles;

[0039] The clamping disc 11 is used to fix the blank. The clamping disc 11 is movably provided with a square guide sleeve 132 that is concentrically distributed and adapted to the first transverse groove 121 and a cylindrical guide cylinder 135 that is eccentrically distributed and adapted to the first inclined groove 125 and the second inclined groove 126, wherein:

[0040] The guide sleeve 132 reciprocates along the first transverse groove 121 to enable the guide cylinder 135 to reciprocate along the first inclined groove 125 or the second inclined groove 126 in sequence and push the clamping plate 11 to rotate relative to the guide cylinder 135 .

[0041] Specifically, a positioning column 119 is provided in the middle of the clamping disk 11, and a plurality of first clamping rods 111 and a plurality of second clamping rods 112 are movably provided on the clamping disk 11. The first clamping rod 111 and the second clamping rod 112 cooperate to clamp the blank. A movable frame 14 is slidably provided on the workbench 1, and an installation shaft 141 for driving the milling cutter head is slidably provided on the movable frame 14. A spring is provided between the guide sleeve 132 and the first transverse groove 121. One end of the first transverse groove 121 connected to the first inclined groove 125 is the tail end, and the other end is the head end.

[0042] Furthermore, the clamping disk 11 is provided with a driving ring 115 for driving the first clamping rod 111 and the second clamping rod 112 to move. The top of the driving ring 115 is provided with a flat thread. The clamping disk 11 is rotatably provided with a driving rod 116 coupled with the driving ring 115 (the coupling method is the same as the coupling of a full worm gear). The top of the clamping disk 11 is provided with a plurality of mortises. The first clamping rod 111 and the second clamping rod 112 are both provided with tenons that match the mortises. The tenon at the bottom of the first clamping rod 111 is provided with a sliding groove that matches the flat thread on the driving ring 115. The second clamping rod 112 is slidably provided with a slider 113. The bottom of the slider 113 is provided with a sliding groove that matches the flat thread. The top of the slider 113 is rotatably provided with a screw 114 that matches the thread of the second clamping rod 112. The top of the screw 114 is provided with a knob. Figure 1-2 As shown, the clamping rods clamped on the inner ring and the outer ring of the blank are the first clamping rod 111, and the clamping rods clamped on the side wall plane and the other arc of the blank are the second clamping rod 112. Before performing the clamping work, the position of the second clamping rod 112 is adjusted according to the size of the blank, and the knob is turned. The knob drives the slider 113 to move relative to the drive ring 115 through the screw 114. The slider 113 is separated from the plane thread on the drive ring 115, and the second clamping rod 112 is adjusted to a suitable position. The knob is then rotated in the opposite direction to recouple the slider 113 with the plane thread. The blank is then placed on the clamping disk 11, and the drive rod 116 is rotated. The drive rod 116 drives the drive ring 115 to rotate the plane thread on the drive ring 115 to push the first clamping rod 111 and the second clamping rod 112 to move, thereby fixing the blank on the clamping disk 11.

[0043] Furthermore, there may be two driving rings 115 in the above embodiment, and the two driving rings 115 drive the clamping rods of the inner ring and the outer ring respectively.

[0044] In the above technical solution, the first clamping rod 111 and the second clamping rod 112 are driven to move, the blank is fixed on the clamping plate 11, the movable frame 14 drives the installation shaft 141 and the cutter head to move, the cutter head mills the blank, mills out the side of a row of protrusions, the cutter head is lifted and the installation shaft 141 moves in the opposite direction with the movable frame 14, the installation shaft 141 pushes the positioning column 119, the positioning column 119 drives the clamping plate 11 and the guide sleeve 132 to move, and the guide sleeve 132 moves along the first transverse groove 121. The spring between the guide sleeve 132 and the first transverse groove 121 is stretched, and the guide cylinder 135 moves along the first inclined groove 125. The guide cylinder 135 pushes the clamping plate 11 to rotate relative to the guide sleeve 132 by a first predetermined angle (the angle between the two side edges of the protrusion). When the guide sleeve 132 moves to the tail end of the first inclined groove 125 (the end of the first inclined groove 125 adjacent to the first transverse groove 121 is the head end, and the other end is the tail end), the clamping plate 11 is locked on the guide sleeve 132 and Separated from the guide cylinder 135, the spring pulls the guide sleeve 132 and the clamping plate 11 to the head end of the first transverse groove 121, and the guide cylinder 135 is reset and recoupled with the clamping plate 11; the milling work is performed again to mill out the other side of the protrusion, and then the clamping plate 11 repeats the movement, and the guide cylinder 135 moves along the second inclined groove 126, pushing the clamping plate 11 to rotate a second predetermined angle (the angle between the two side edges of two adjacent protrusions) relative to the guide sleeve 132, and the guide sleeve 132 and the clamping plate 11 move to the head end of the first transverse groove 121 to mill the side edges of another row of protrusions, and repeat the above operation. After the milling of multiple rows of protrusions is completed, the protrusions can be fine-machined to give them a preset shape; the angle of each rotation of the clamping plate 11 is determined by the specific first inclined groove 125 and second inclined groove 126, which is equivalent to each rotation of the clamping plate 11 being calibrated so that the error in the angle of rotation of the clamping plate 11 is small and the error will not accumulate.

[0045] Example 2

[0046] A guide piece 146 is hinged in the guide groove 12 , and the guide piece 146 rotates to open the first inclined groove 125 and the second inclined groove 126 alternately.

[0047] Specifically, the guide piece 146 is hinged at the connection between the first inclined slot 125 and the second inclined slot 126 .

[0048] Furthermore, after the milling of one side of a row of bumps is completed, the mounting shaft 141 pushes the clamping disc 11, the guide sleeve 132 and the guide cylinder 135 to move. At this time, the guide piece 146 seals the second bevel 126, and the guide cylinder 135 enters the first bevel 125 under the guidance of the guide piece 146, pushing the clamping disc 11 to rotate the first predetermined angle relative to the guide sleeve 132 to facilitate the milling of the row of bumps. Then the guide sleeve 132 and the guide cylinder 135 are reset, and the guide piece 146 rotates to the other side to seal the first bevel 125 and open the second bevel 126 for the next work.

[0049] The guide sleeve 132 is provided with a locking plate 131 for locking the guide sleeve 132 between the workbench 1 and the clamping plate 11 . The clamping plate 11 is pushed to unlock the locking plate 131 .

[0050] Specifically, a limit plate 13 is provided on the guide sleeve 132, and a limit bar 145 is provided on the workbench 1 to fit with the limit plate 13. The limit bar 145 cooperates with the limit plate 13 to limit the guide sleeve 132 to move only along the first transverse groove 121. The lock disk 131 is provided with protrusions distributed in a circumferential array, and the bottom of the clamping disk 11 is provided with a plurality of grooves adapted to the protrusions. The limit plate 13 is provided with grooves adapted to the plurality of protrusions. The lock disk 131 is provided with a push rod 136 extending to the positioning column 119. The top of the push rod 136 is hemispherical, and the bottom of the lock disk 131 is provided with a guide rod extending to the guide sleeve 132. 133, a spring is provided between the guide rod 133 and the guide sleeve 132, a locking block 134 adapted to the middle channel of the guide sleeve 132 is provided on the workbench 1, a slope is provided on the side wall of the locking block 134, a spring is provided between the locking block 134 and the workbench 1, a plurality of fan-shaped blocks 117 are slidingly provided on the positioning column 119, a push rod 118 extending to the inside of the positioning column 119 is provided on the fan-shaped block 117, a spring is provided between the fan-shaped block 117 and the positioning column 119, and a plurality of fan-shaped blocks 117 are distributed in a circular array on the positioning column 119 to ensure that the mounting shaft 141 can push a fan-shaped block 117 from any angle.

[0051] Furthermore, in the process of the installation shaft 141 approaching the positioning column 119, the installation shaft 141 pushes one of the sector blocks 117, and the push rod 118 on the sector block 117 moves along the hemispherical shape at the top of the push rod 136, pushing the push rod 136 to move downward, and the push rod 136 pushes the locking plate 131 to move downward, and the locking plate 131 retracts into the limit plate 13 and separates from the clamping plate 11. At this time, the clamping plate 11 can rotate relative to the guide sleeve 132, and the clamping plate 11 pushes the locking block 134 through the guide rod 133, so that the locking block 134 is separated from the guide sleeve 132, and the guide sleeve 132 can move along the first transverse groove 121. The installation shaft 141 continues to move, pushing the guide sleeve 132 to move to the first transverse groove 121. The tail end of the first transverse groove 121 is moved by the spring, and then the mounting shaft 141 moves in the direction away from the positioning column 119. The sector block 117 is no longer pushed and resets under the action of the spring. The guide rod 133 moves up under the action of the spring, pushing the lock plate 131 up. The protruding piece on the lock plate 131 spans the limit plate 13 and the clamping plate 11, locking the clamping plate 11 on the limit plate 13. The guide sleeve 132 moves toward the head end of the first transverse groove 121 under the pull of the spring, and the guide sleeve 132 pushes the lock block 134 along the slope of the lock block 134, so that the lock block 134 retracts into the workbench 1. When the lock block 134 is facing the guide sleeve 132, the lock block 134 is inserted into the guide sleeve 132 under the action of the spring, locking the peach at the head end of the first transverse groove 121.

[0052] A second transverse groove 122 and a third transverse groove 123 parallel to the first transverse groove 121 are respectively provided at the tail end of the first oblique groove 125 and the tail end of the second oblique groove 126 .

[0053] Specifically, the guide sleeve 132 moves to the tail end of the first transverse groove 121, and then the mounting shaft 141 moves in the direction away from the positioning column 119. The sector block 117 is no longer pushed and resets under the action of the spring. The guide rod 133 moves upward under the action of the spring, pushing the locking plate 131 to move upward. The protrusion on the locking plate 131 spans the limit plate 13 and the clamping plate 11, locking the clamping plate 11 on the limit plate 13. At this time, the guide cylinder 135 also moves to the tail end of the first inclined groove 125 or the second inclined groove 126. Then the guide sleeve 132 moves toward the head end of the first transverse groove 121 under the pull of the spring, and the guide cylinder 135 moves synchronously with the clamping plate 11 along the first inclined groove 125 or the second inclined groove 126.

[0054] The connections between the second transverse groove 122 and the first inclined groove 125 and the second inclined groove 126 are all hinged with movable pieces.

[0055] Specifically, the plurality of movable pieces are respectively a first movable piece 127, a second movable piece 128 and a third movable piece 129. A torsion spring is provided between the first movable piece 127 and the workbench 1, between the second movable piece 128 and the workbench 1, and between the third movable piece 129 and the workbench 1. The first movable piece 127 makes the rear half of the first inclined slot 125 in a normally closed state under the action of the torsion spring, the second movable piece 128 makes the connection between the second transverse slot 122 and the second inclined slot 126 in a normally closed state under the action of the torsion spring, and the third movable piece 129 makes the middle part of the second inclined slot 126 in a normally closed state (as shown in FIG. Figure 7 shown).

[0056] Furthermore, during the movement of the guide cylinder 135 along the first inclined groove 125, the guide cylinder 135 pushes the first movable piece 127, and the first movable piece 127 makes room for the guide cylinder 135 to move. The guide cylinder 135 continues to move and separates from the first movable piece 127. The first movable piece 127 closes the first inclined groove 125, and the guide sleeve 132 moves to the tail end of the first transverse groove 121. Then, the guide sleeve 132 moves in the opposite direction, and the guide cylinder 135 moves along the second transverse groove 122 under the guidance of the first movable piece 127. And push the second movable piece 128, the second movable piece 128 and the third movable piece 129 cooperate to seal the connection between the second transverse groove 122 and the second inclined groove 126, and the guide sleeve 132 moves along the second transverse groove 122; in the process of the guide cylinder 135 moving along the second inclined groove 126, the guide cylinder 135 pushes the third movable piece 129 to open the second inclined groove 126. When the guide cylinder 135 moves to the end of the second inclined groove 126, the guide sleeve 132 moves in the opposite direction, and the guide cylinder 135 moves along the third transverse groove 123.

[0057] Fins 147 are symmetrically arranged on the guide piece 146 and are vertically distributed and extend into the first inclined slot 125 and the second inclined slot 126 respectively.

[0058] Specifically, there is a magnetic fit between the end of the guide piece 146 and the side wall of the first inclined groove 125 and the side wall of the second inclined groove 126 .

[0059] Furthermore, when the guide piece 146 seals the second chute 126, the guide cylinder 135 moves along the first chute 125 and pushes the guide piece 146 to extend into the fin 147 in the first chute 125. The fin 147 drives the guide piece 146 to rotate, so that the guide piece 146 is attracted to the side wall of the first chute 125. At this time, the second chute 126 is opened and the first chute 125 is closed. When working next time, the guide cylinder 135 can move along the second chute 126, so that the first chute 125 and the second chute 126 work alternately.

[0061] A locking rod 137 is slidably provided in the guide cylinder 135 , and the guide cylinder 135 moves to a predetermined position to separate the locking rod 137 from the clamping disk 11 .

[0062] Specifically, a plurality of positioning holes 138 distributed in a circular array and adapted to the locking rods 137 are defined at the bottom of the clamping disk 11 .

[0063] Furthermore, in the process of the guide sleeve 132 moving along the first transverse groove 121 and the guide cylinder 135 moving along the first inclined groove 125 or the second inclined groove 126, the guide cylinder 135 drives the clamping disk 11 to rotate relative to the guide sleeve 132 through the locking rod 137.

[0065] Specifically, a magnet that magnetically cooperates with the locking rod 137 is provided in the positioning hole 138 , and there is magnetic cooperation between the strip magnet 139 and the locking rod 137 .

[0066] Furthermore, when the guide cylinder 135 moves along the first inclined groove 125 or the second inclined groove 126, the locking rod 137 is inserted into the positioning hole 138 under the attraction of the magnet in the positioning hole 138. When the guide cylinder 135 moves along the second transverse groove 122 or the third transverse groove 123 to the vertical groove 124, the strip magnet 139 attracts the locking rod 137, and the locking rod 137 overcomes the attraction of the magnet in the positioning hole 138 and moves downward. The locking rod 137 is separated from the clamping disk 11, and the guide cylinder 135 is also separated from the clamping disk 11.

[0069] Furthermore, in the process of the guide sleeve 132 moving from the head end to the tail end of the first transverse groove 121, the guide sleeve 132 drives the push block 144 to move through the cable 142, and the spring between the push block 144 and the workbench 1 accumulates elastic potential energy. When the guide cylinder 135 moves to above the strip magnet 139, the spring between the push block 144 and the workbench 1 releases the elastic potential energy, pushing the guide cylinder 135 to move along the vertical groove 124 to the first transverse groove 121, and the locking rod 137 on the guide cylinder 135 is facing another positioning hole 138.
