Description

Technical Field

[0001] The present invention relates to the technical field of oil guiding cavities, and more particularly to an automatic processing device for oil guiding cavities. Background Art

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

[0003] The oil guiding cavity is arranged at the bottom of the body and can be regarded as an insulated end ring with a shell. There are hook release notches at the four corners of the cavity to facilitate the release of the tooling during the coil sleeving process. During installation, the transformer oil enters through two openings at the upper part of the cavity and is evenly introduced into the coil through small round holes between the grids. After the coil sleeving is completed, the cover plate and pads are installed and sealed with glue, and the periphery is locked and fastened with screws. At the same time, it is necessary to ensure that the bottom end ring of the coil is flat to prevent the cardboard from arching and affecting the installation of the cover plate. Its function is remarkable. By reasonably arranging the oil flow rate entering the body, it can accurately control the oil flow rate and speed introduced into the winding, avoiding the charging phenomenon caused by too high an oil flow rate. At a low oil flow rate, the reasonable distribution of the oil flow between the windings can be realized, effectively eliminating the dead oil area and oil flow "dead corners" in the horizontal oil ducts, strengthening the coil heat dissipation, reducing the average temperature rise of the coil, avoiding local overheating or even burning of the winding, ensuring the stable operation of the transformer, extending its service life, and improving the product quality and operation efficiency.

[0004] The oil guiding cavity is processed from laminated boards (multiple layers of insulating cardboard), and there are multiple convex blocks radially distributed in the oil guiding cavity. The multiple convex blocks are used to separate the wire harnesses and support the cover plate. The processing of the oil guiding cavity is generally overall milling. First, the blank is fixed on the fixed seat, and then the contour of the convex blocks is milled on the blank. After milling the side of a column of convex blocks, the fixed seat is rotated so that the milling machine can mill the side of the other side of the column of convex blocks. However, there is a certain error in the rotation angle of the fixed seat, and during the continuous multiple rotations, the error in the rotation angle of the fixed seat accumulates continuously, and finally affects the milling accuracy of the blank, resulting in a large difference between the included angle between the finally milled column of convex blocks and the initially milled column of convex blocks and the designed angle, thereby affecting the subsequent use. Summary of the Invention

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

[0006] To achieve the above purpose, the present invention provides an automatic processing device for oil guiding cavities, including a workbench, and the workbench is provided with: A guiding groove, which includes a first transverse groove, a first inclined groove and a second inclined groove that are connected to the tail end of the first transverse groove and have different inclination angles; A clamping disk, which is used to fix a blank. A square guide sleeve that is concentrically distributed with the clamping disk and adapted to the first transverse groove, and a cylindrical guide cylinder that is eccentrically distributed and adapted to the first inclined groove and the second inclined groove are movably arranged on the clamping disk, where: The guide sleeve reciprocates along the first transverse groove so that the guide cylinder reciprocates along the first inclined groove or the second inclined groove in sequence and pushes the clamping disk to rotate relative to the guide cylinder.

[0007] Preferably, a guide piece is hinged in the guide groove, and the guide piece rotates to alternately open the first inclined groove and the second inclined groove.

[0008] Preferably, a locking disk that locks the guide sleeve between the workbench and the clamping disk is arranged on the guide sleeve, and the clamping disk is pushed to unlock the locking disk.

[0009] Preferably, a second transverse groove and a third transverse groove parallel to the first transverse groove are respectively arranged at the tail ends of the first inclined groove and the second inclined groove.

[0010] Preferably, movable pieces are hinged at the connection positions of the second transverse groove with the first inclined groove and the second inclined groove.

[0011] Preferably, fins that are vertically distributed and respectively extend into the first inclined groove and the second inclined groove are symmetrically arranged on the guide piece.

[0012] Preferably, a locking rod is slidably arranged in the guide cylinder, and the guide cylinder moves to a predetermined position to separate the locking rod from the clamping disk.

[0013] Preferably, a vertical groove communicating with the first transverse groove, the second transverse groove and the third transverse groove is formed on the workbench, and a strip-shaped magnet for pulling the locking rod to move downward is arranged in the vertical groove.

[0014] Preferably, a push block for pushing the guide cylinder to reset is arranged in the first transverse groove, and the guide sleeve moves to move the push block to the tail end of the vertical groove and store energy.

[0015] Preferably, an insertion block for fixing the push block is arranged on the strip-shaped magnet, and the strip-shaped magnet is coupled with the locking rod to unlock the push block.

[0016] In the above technical solution, an automatic processing device for an oil guiding cavity provided by the present invention has the following beneficial effects: during operation, the first clamping rod and the second clamping rod are driven to move to fix the blank on the clamping disk. The movable frame drives the mounting shaft and the cutter head to move, and the cutter head mills the blank to mill out the side edges of a row of convex blocks. The cutter head is lifted and the mounting shaft moves in the reverse direction with the movable frame. The mounting shaft pushes the positioning post, and the positioning post drives the clamping disk and the guide sleeve to move. The guide sleeve moves along the first horizontal groove, and the spring between the guide sleeve and the first horizontal groove is stretched. The guide cylinder moves along the first inclined groove, and the guide cylinder pushes the clamping disk to rotate relative to the guide sleeve by a first predetermined angle (the angle between two side edges of the convex block). When the guide sleeve moves to the end of the first inclined groove (the end adjacent to the first horizontal groove is the head end, and the other end is the tail end), the clamping disk is locked on the guide sleeve and separated from the guide cylinder. The spring pulls the guide sleeve and the clamping disk to move to the head end of the first horizontal groove, and the guide cylinder resets and couples with the clamping disk again; the milling operation is carried out again to mill out the other side edge of the convex block. Then the clamping disk moves repeatedly, the guide cylinder moves along the second inclined groove, and pushes the clamping disk to rotate relative to the guide sleeve by a second predetermined angle (the angle between two side edges of two adjacent convex blocks). The guide sleeve and the clamping disk move to the head end of the first horizontal groove to mill the side edges of another row of convex blocks. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Embodiment 1

[0022] As Figure 1-12 shown, an automatic processing device for an oil guiding cavity includes a workbench 1, and the workbench 1 is provided with: A guide groove 12, which includes a first transverse groove 121, a first inclined groove 125 and a second inclined groove 126 that are communicated with the tail end of the first transverse groove 121 and have different inclination angles; A clamping disk 11, which is used to fix a blank. A square guide sleeve 132 that is concentrically distributed with the clamping disk 11 and is adapted to the first transverse groove 121 and a cylindrical guide cylinder 135 that is eccentrically distributed and is adapted to the first inclined groove 125 and the second inclined groove 126 are movably arranged on the clamping disk 11, wherein: The guide sleeve 132 reciprocates along the first transverse groove 121 so that the guide cylinder 135 reciprocates along the first inclined groove 125 or the second inclined groove 126 in sequence and pushes the clamping disk 11 to rotate relative to the guide cylinder 135.

[0023] Specifically, a positioning post 119 is provided in the middle of the clamping disc 11. A plurality of first clamping rods 111 and a plurality of second clamping rods 112 are movably arranged on the clamping disc 11. The first clamping rods 111 and the second clamping rods 112 cooperate to clamp the blank. A movable frame 14 is slidably arranged on the workbench 1. A mounting shaft 141 for driving the milling cutter head is slidably arranged on the movable frame 14. A spring is arranged 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.

[0024] Further, a driving ring 115 for driving the first clamping rods 111 and the second clamping rods 112 to move is arranged in the clamping disc 11. A flat thread is arranged on the top of the driving ring 115. A driving rod 116 coupled with the driving ring 115 (the coupling method is the same as that of the full worm and worm gear) is rotatably arranged on the clamping disc 11. A plurality of tenon grooves are formed on the top of the clamping disc 11. Tenon blocks adapted to the tenon grooves are arranged on both the first clamping rods 111 and the second clamping rods 112. A chute adapted to the flat thread on the driving ring 115 is formed on the tenon block at the bottom of the first clamping rod 111. A slider 113 is slidably arranged on the second clamping rod 112. A chute adapted to the flat thread is arranged at the bottom of the slider 113. A screw rod 114 threadedly engaged with the second clamping rod 112 is rotatably arranged on the top of the slider 113. A knob is arranged on the top of the screw rod 114. As Figure 1-2 shown, the clamping rods on the inner ring and the positive arc of the outer ring of the blank are all first clamping rods 111, and the clamping rods on the side wall plane and another arc of the blank are second clamping rods 112. Before the clamping work, adjust the position of the second clamping rod 112 according to the size of the blank. Rotate the knob. The knob drives the slider 113 to move relative to the driving ring 115 through the screw rod 114. The slider 113 is separated from the flat thread on the driving ring 115. Adjust the second clamping rod 112 to a suitable position, and then rotate the knob in the reverse direction to make the slider 113 re-couple with the flat thread. Then place the blank on the clamping disc 11. Rotate the driving rod 116. The driving rod 116 drives the driving ring 115 to rotate. The flat thread on the driving ring 115 pushes the first clamping rods 111 and the second clamping rods 112 to move, and fixes the blank on the clamping disc 11.

[0025] Still further, two driving rings 115 in the above embodiments can be used, and the two driving rings 115 respectively drive the clamping rods of the inner and outer circles.

[0026] In the above technical solution, the first clamping rod 111 and the second clamping rod 112 are driven to move, fixing the blank on the clamping disk 11. The movable frame 14 drives the mounting shaft 141 and the tool head to move. The tool head mills the blank to mill out the side edges of a row of bumps. The tool head is lifted and the mounting shaft 141 moves in the reverse direction with the movable frame 14. The mounting shaft 141 pushes the positioning post 119, and the positioning post 119 drives the clamping disk 11 and the guide sleeve 132 to move. The guide sleeve 132 moves along the first transverse groove 121, and the spring between the guide sleeve 132 and the first transverse groove 121 is stretched. The guide cylinder 135 moves along the first inclined groove 125, and the guide cylinder 135 pushes the clamping disk 11 to rotate relative to the guide sleeve 132 by a first predetermined angle (the angle between two side edges of the bump). When the guide sleeve 132 moves to the end of the first inclined groove 125 (the end adjacent to the first transverse groove 121 is the head end, and the other end is the tail end), the clamping disk 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 disk 11 to move to the head end of the first transverse groove 121. The guide cylinder 135 resets and re-couples with the clamping disk 11; the milling work is carried out again to mill out the other side edge of the bump. Then the clamping disk 11 moves repeatedly. The guide cylinder 135 moves along the second inclined groove 126, pushing the clamping disk 11 to rotate relative to the guide sleeve 132 by a second predetermined angle (the angle between two side edges of adjacent bumps). The guide sleeve 132 and the clamping disk 11 move to the head end of the first transverse groove 121 to mill the side edges of another row of bumps. By repeating the above operations, after milling multiple rows of bumps, the bumps can be finely processed to present a preset shape; the angle of each rotation of the clamping disk 11 is determined by specific first inclined groove 125 and second inclined groove 126, which is equivalent to calibrating each rotation of the clamping disk 11, so that the error of the rotation angle of the clamping disk 11 is small and the error will not accumulate.

[0027] Embodiment 2

[0028] A guide piece 146 is hinged in the guide groove 12, and the guide piece 146 rotates to alternately open the first inclined groove 125 and the second inclined groove 126.

[0029] Specifically, the guide piece 146 is hinged at the connection of the first inclined groove 125 and the second inclined groove 126.

[0030] Further, after milling one side of a row of bumps, the mounting shaft 141 pushes the clamping disk 11, the guide sleeve 132 and the guide cylinder 135 to move. At this time, the guide piece 146 seals the second inclined groove 126, and the guide cylinder 135 enters the first inclined groove 125 under the guidance of the guide piece 146, pushing the clamping disk 11 to rotate relative to the guide sleeve 132 by a first predetermined angle, facilitating the milling of this row of bumps. Then the guide sleeve 132 and the guide cylinder 135 reset, and the guide piece 146 rotates to the other side, sealing the first inclined groove 125 and opening the second inclined groove 126 for the next operation.

[0031] A locking plate 131 for locking the guide sleeve 132 between the workbench 1 and the clamping disc 11 is provided on the guide sleeve 132, and the clamping disc 11 is pushed to unlock the locking plate 131.

[0032] Specifically, a limiting plate 13 is provided on the guide sleeve 132, a limiting strip 145 that fits with the limiting plate 13 is provided on the workbench 1, and the limiting strip 145 cooperates with the limiting plate 13 to limit the guide sleeve 132 to move only along the first transverse groove 121. The locking plate 131 is provided with tabs distributed in a circumferential array, and a plurality of grooves adapted to the tabs are formed at the bottom of the clamping disc 11. Grooves adapted to the plurality of tabs are formed on the limiting plate 13. A ejector rod 136 extending into the positioning post 119 is provided on the locking plate 131. The top of the ejector rod 136 is hemispherical. A guide rod 133 extending into the guide sleeve 132 is provided at the bottom of the locking plate 131. 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 sector blocks 117 are slidably arranged on the positioning post 119. A push rod 118 extending into the interior of the positioning post 119 is provided on the sector block 117. A spring is provided between the sector block 117 and the positioning post 119. The plurality of sector blocks 117 are arranged on the positioning post 119 in a circumferential array, ensuring that the mounting shaft 141 can be pushed to one of the sector blocks 117 from any angle.

[0033] Further, during the process of the mounting shaft 141 approaching the positioning post 119, the mounting shaft 141 pushes one of the sector blocks 117. The push rod 118 on the sector block 117 moves along the hemispherical shape at the top of the ejector rod 136, pushing the ejector rod 136 downward. The ejector rod 136 pushes the locking disc 131 downward, and the locking disc 131 retracts into the limiting plate 13 and separates from the clamping disc 11. At this time, the clamping disc 11 can rotate relative to the guide sleeve 132, and the clamping disc 11 pushes the locking block 134 through the guide rod 133, causing the locking block 134 to separate from the guide sleeve 132. The guide sleeve 132 can move along the first transverse groove 121. The mounting shaft 141 continues to move, pushing the guide sleeve 132 to the end of the first transverse groove 121. Then the mounting shaft 141 moves away from the positioning post 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 disc 131 upward. The tab on the locking disc 131 straddles the limiting plate 13 and the clamping disc 11, locking the clamping disc 11 on the limiting plate 13. The guide sleeve 132 moves toward the beginning of the first transverse groove 121 under the pulling of the spring. The guide sleeve 132 pushes against the locking block 134 along the slope of the locking block 134, causing the locking block 134 to retract into the workbench 1. When the locking block 134 is aligned with the guide sleeve 132, the locking block 134 inserts into the guide sleeve 132 under the action of the spring, locking the guide sleeve 132 at the beginning of the first transverse groove 121.

[0034] At the ends of the first inclined groove 125 and the second inclined groove 126, a second transverse groove 122 and a third transverse groove 123 parallel to the first transverse groove 121 are respectively provided.

[0035] Specifically, when the guide sleeve 132 moves to the end of the first transverse groove 121, then the mounting shaft 141 moves away from the positioning post 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 disc 131 upward. The tab on the locking disc 131 straddles the limiting plate 13 and the clamping disc 11, locking the clamping disc 11 on the limiting plate 13. At this time, the guide cylinder 135 also just moves to the end of the first inclined groove 125 or the second inclined groove 126. Then the guide sleeve 132 moves toward the beginning of the first transverse groove 121 under the pulling of the spring, and the guide cylinder 135 moves synchronously with the clamping disc 11 along the first inclined groove 125 or the second inclined groove 126.

[0036] Activity pieces are hinged at the joints of the second transverse groove 122 with the first inclined groove 125 and the second inclined groove 126.

[0037] Specifically, the multiple movable pieces are respectively a first movable piece 127, a second movable piece 128, and a third movable piece 129. Torsion springs are 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. Under the action of the torsion spring, the second half of the first inclined groove 125 is in a normally closed state by the first movable piece 127, the connection between the second transverse groove 122 and the second inclined groove 126 is in a normally closed state by the second movable piece 128, and the middle part of the second inclined groove 126 is in a normally closed state by the third movable piece 129 (as Figure 7 shown).

[0038] Further, during the process of the guide cylinder 135 moving along the first inclined groove 125, the guide cylinder 135 pushes the first movable piece 127, and the first movable piece 127 makes way for the space 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. The guide sleeve 132 moves to the end of the first transverse groove 121. Then the guide sleeve 132 moves in the reverse direction. The guide cylinder 135 moves along the second transverse groove 122 under the guidance of the first movable piece 127 and pushes 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. The guide sleeve 132 moves along the second transverse groove 122. During 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 reverse direction, and the guide cylinder 135 moves along the third transverse groove 123.

[0039] Fins 147 are symmetrically arranged on the guide piece 146 and are vertically distributed and extend into the first inclined groove 125 and the second inclined groove 126 respectively.

[0040] Specifically, there is a magnetic attraction fit between the end of the guide piece 146 and the side walls of the first inclined groove 125 and the second inclined groove 126.

[0041] Further, when the guide piece 146 seals the second inclined groove 126, the guide cylinder 135 moves along the first inclined groove 125 and pushes the fin 147 of the guide piece 146 extending into the first inclined groove 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 inclined groove 125. At this time, the second inclined groove 126 is opened and the first inclined groove 125 is closed. During the next operation, the guide cylinder 135 can move along the second inclined groove 126, enabling the first inclined groove 125 and the second inclined groove 126 to work alternately.

[0042] Embodiment 3

[0043] A locking rod 137 is slidably arranged in the guiding cylinder 135. The guiding cylinder 135 moves to a predetermined position so that the locking rod 137 is separated from the clamping disc 11.

[0044] Specifically, a plurality of positioning holes 138 which are arranged in a circumferential array and are adapted to the locking rod 137 are formed at the bottom of the clamping disc 11.

[0045] Furthermore, during the process that the guiding sleeve 132 moves along the first transverse groove 121 and the guiding cylinder 135 moves along the first inclined groove 125 or the second inclined groove 126, the guiding cylinder 135 drives the clamping disc 11 to rotate relative to the guiding sleeve 132 through the locking rod 137. When the guiding cylinder 135 moves to the predetermined position, the locking rod 137 is separated from the clamping disc 11, and the clamping disc 11 can continue to move along with the guiding sleeve 132, and the guiding cylinder 135 moves relative to the clamping disc 11.

[0046] A vertical groove 124 communicating with the first transverse groove 121, the second transverse groove 122 and the third transverse groove 123 is formed on the workbench 1, and a strip-shaped magnet 139 for pulling the locking rod 137 to move downward is arranged in the vertical groove 124.

[0047] Specifically, a magnet magnetically coupled with the locking rod 137 is arranged in the positioning hole 138, and there is a magnetic coupling between the strip-shaped magnet 139 and the locking rod 137.

[0048] Furthermore, during the process that the guiding 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 guiding cylinder 135 moves along the second transverse groove 122 or the third transverse groove 123 into the vertical groove 124, the strip-shaped magnet 139 attracts the locking rod 137, and the locking rod 137 moves downward against the attraction of the magnet in the positioning hole 138. The locking rod 137 is separated from the clamping disc 11, and the guiding cylinder 135 is also separated from the clamping disc 11.

[0049] A pushing block 144 for pushing the guiding cylinder 135 to reset is arranged in the first transverse groove 121. The guiding sleeve 132 moves to make the pushing block 144 move to the tail end of the vertical groove 124 and store energy.

[0050] Specifically, a spring is arranged between the pushing block 144 and the workbench 1, a cable 142 is arranged between the guiding sleeve 132 and the pushing block 144, a groove adapted to the side wall of the guiding cylinder 135 is arranged on the side wall of the pushing block 144, and the end of the vertical groove 124 far from the first transverse groove 121 is the tail end.

[0051] Further, during 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. The spring between the push block 144 and the workbench 1 accumulates elastic potential energy. When the guide cylinder 135 moves 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 into the first transverse groove 121. And the locking rod 137 on the guide cylinder 135 is exactly opposite to another positioning hole 138. The magnet in this positioning hole 138 attracts the locking rod 137 to move upward, and the locking rod 137 is inserted into this positioning hole 138, connecting the guide cylinder 135 with the clamping disc 11 together.

[0052] An insertion block 143 for fixing the push block 144 is arranged on the strip magnet 139, and the strip magnet 139 is coupled with the locking rod 137 to unlock the push block 144.

[0053] Specifically, a spring is arranged between the strip magnet 139 and the workbench 1. Ramps are arranged on the side walls of the strip magnet 139 close to the second transverse groove 122 and the third transverse groove 123. Ramps are arranged on the side wall of the insertion block 143 close to the push block 144. A groove adapted to the insertion block 143 is formed at the bottom of the insertion block 143.

[0054] Further, during 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. The spring between the push block 144 and the workbench 1 accumulates elastic potential energy. The push block 144 gradually approaches the insertion block 143 and moves along the ramp on the insertion block 143 until the insertion block 143 is exactly opposite to the groove at the bottom of the push block 144. The insertion block 143 is inserted into the push block 144 under the pushing of the spring. When the guide cylinder 135 moves along the ramp on the strip magnet 139 to above the strip magnet 139, the strip magnet 139 attracts the locking rod 137, and the locking rod 137 moves downward against the attraction of the magnet in the positioning hole 138. The locking rod 137 is separated from the clamping disc 11, and the guide cylinder 135 is also separated from the clamping disc 11. The guide cylinder 135 pushes the strip magnet 139 to drive the insertion block 143 to move downward, unlocking the push block 144. 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 into the first transverse groove 121. And the locking rod 137 on the guide cylinder 135 is exactly opposite to another positioning hole 138. The magnet in this positioning hole 138 attracts the locking rod 137 to move upward, and the locking rod 137 is inserted into this positioning hole 138, connecting the guide cylinder 135 with the clamping disc 11 together.

Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
