Description

Technical Field

[0001] This utility model relates to the field of transformer frame production technology, specifically a transformer frame production device. Background Technology

[0002] The transformer bobbin is one of the important structural components of a transformer, providing space for the copper wires inside the transformer to be wound. The transformer bobbin is injection molded by an injection molding machine. Burrs and rough edges can easily form on the bobbin at the sprue, mold gaps, and other locations. After injection molding, the bobbin needs to undergo multiple deburring processes.

[0003] Existing drum polishing devices remove burrs by placing the polishing abrasive and the frame together inside the drum and rubbing the abrasive against the frame. However, after polishing, the transformer frame and the polishing abrasive need to be removed from the drum together for sorting. During the removal process, some transformer frame pins are easily stuck in the gaps of the drum, making it very inconvenient to remove. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a transformer frame production device to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transformer frame production device, comprising two mounting bases, with a first motor and a second motor respectively mounted on one side of each mounting base. The output end of the first motor is connected to a fixed base, and a first gear is mounted on the outer surface of the output end of the first motor. The output end of the second motor is connected to a roller, which is located on the outer surface of the fixed base. A sealing cover is bolted to the feed port of the roller. A limiting seat is connected to one side of the roller, and a movable rod is connected to the top of the limiting seat via a rotating rod. A placement rod is placed inside the fixed base, and a limiting plate is connected to the outer surface of the placement rod. A second gear is mounted on one end of the placement rod.

[0006] Furthermore, the fixed base has an "I" shaped cross-section and is rotatably connected to the roller.

[0007] By adopting the above technical solution, when grinding the transformer frame, the workers first place multiple transformer frames on the placement rods, then insert one end of the placement rod into the fixing hole, and at the same time put the other end into the groove, so that the first gear and the second gear mesh. Rotate the fixing seat, and install all the placement rods in sequence. After installation, put the grinding sand into the inside of the drum and fix the sealing cover. At the same time, start the first motor and the second motor, so that the first motor drives the fixing seat to rotate forward and the second motor drives the drum to rotate in reverse, thereby making the grinding sand rub against the transformer frame, and grinding the burrs on the edge of the transformer frame through friction.

[0008] Furthermore, the first gear meshes with the second gear.

[0009] By adopting the above technical solution, under the drive of the first motor, the first gear meshes with the second gear, causing the second gear to drive the placement rod to rotate, thereby causing the transformer skeleton on the placement rod to rotate. The rotation increases the contact area between the transformer skeleton and the abrasive, thereby improving the polishing effect of the abrasive on the transformer skeleton.

[0010] Furthermore, the outer surface of the fixing base has multiple grooves on one side, and the multiple grooves are distributed in a ring array.

[0011] By adopting the above technical solution, one side of the limiting plate corresponds to the groove, and the limiting plate seals the groove, thereby preventing the abrasive from leaking out of the roller and causing waste. Since the edges of the transformer frame are irregular and have gaps, the groove and the limiting plate cooperate to fix the positions of multiple placement rods, so that the transformer frame on each placement rod will not contact the transformer frame on another placement rod, thereby avoiding the transformer frames from getting stuck together and causing incomplete grinding.

[0012] Furthermore, the placement rod is detachably connected to the fixing seat via a groove.

[0013] By adopting the above technical solution, the transformer skeleton to be ground is fixed by the placement rod, which avoids direct contact between the transformer skeleton and the roller during grinding. After grinding is completed, the sealing cover is opened and the placement rods are taken out one by one, so that all the transformer skeletons can be taken out. This avoids the situation where the pins of the transformer skeleton are stuck in the gap of the roller, which would make it inconvenient to take them out.

[0014] Furthermore, a fixing hole is provided on one side of the inside of the fixing base, and one end of the placement rod is detachably connected to the fixing hole.

[0015] By adopting the above technical solution, the position of the placement rod is fixed by the cooperation of the fixing hole and the limiting plate. Driven by the output end of the first motor, the first gear and the second gear mesh, so that the placement rod rotates while following the rotation of the fixing seat. The placement rod is fixed by the cooperation of the limiting seat and the groove, thereby avoiding the displacement of the placement rod position under the action of centrifugal force, which would affect the practicality of the device.

[0016] Furthermore, both the limiting seat and the movable rod have pin holes on their outer surfaces, and the two pin holes are connected by a cotter pin.

[0017] By adopting the above technical solution, after the placement rods are placed in sequence, the movable rod is rotated so that its pin hole corresponds with the pin hole on the limit seat. Then, the cotter pin is inserted into the two pin holes and fixed by the cotter pin, so that the movable rod and the limit seat are integrated and cooperate with the groove to fix the placement rod, thus preventing the movement of the placement rod from affecting the meshing of the first gear and the second gear.

[0018] Furthermore, the movable rod corresponds to the position of the sealing cover.

[0019] By adopting the above technical solution, when the grinding is finished, the staff first opens the sealing cover, then removes the cotter pin and opens the movable rod, releasing the limit of one of the placement rods, making it convenient for the staff to take out all the transformer frames on that placement rod. By rotating the fixed base, the remaining placement rods are rotated to the corresponding positions of the roller discharge port and taken out, thus eliminating the need to take out all the transformer frames and grinding sand together and then sort them, improving work efficiency.

[0020] Furthermore, both the limiting seat and the movable rod are arc-shaped.

[0021] By adopting the above technical solution, with the cotter pin fixed, the limiting seat and the movable rod are combined into a circular whole and cooperate with the groove to limit the position of the placement rod, preventing the placement rod from shifting under the action of centrifugal force. Through the arc-shaped setting, this whole is always in contact with the placement rod at only one point, thereby reducing the contact area between the limiting seat and the movable rod and the placement rod, and extending the service life of the placement rod, the limiting seat and the movable rod.

[0022] Furthermore, a holding frame is placed between the two mounting bases via a placement plate, and a sieve is placed inside the holding frame.

[0023] By adopting the above technical solution, after the transformer frame is removed, the drum is rotated so that the discharge port of the drum faces downward. Under the action of gravity, the grinding sand and burrs fall into the collection frame together. The grinding sand is screened by a screen so that the burrs and unqualified grinding sand are separated from the qualified grinding sand, and the qualified grinding sand is recycled.

[0024] In summary, the present invention has the following main advantages: 1. This utility model, by setting a fixed base, a groove and a placement rod, allows all the transformer skeletons to be ground to be placed on multiple placement rods in sequence, and then the placement rods are fixed to the fixed base. This prevents the transformer skeletons from contacting the inner wall of the drum during grinding, thus avoiding the situation where the pins of the transformer skeletons get stuck in the gaps of the drum and cause inconvenience in handling. After grinding, the fixed base is rotated, and the remaining placement rods are rotated to the position corresponding to the discharge port of the drum in sequence and then removed. This eliminates the need to remove all the transformer skeletons and grinding sand together and then sort them, thus improving work efficiency. 2. This utility model is equipped with a first gear and a second gear. Driven by the output end of the first motor, the first gear meshes with the second gear, causing the placement rod to rotate while following the rotation of the fixed base. The rotation increases the contact area between the transformer frame and the abrasive, thereby improving the polishing effect of the abrasive on the transformer frame. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] Example 1: A production apparatus for a transformer frame, such as Figures 1-5As shown, the device includes two mounting bases 1. A first motor 2 and a second motor 3 are respectively mounted on one side of each mounting base 1. The output end of the first motor 2 is connected to a fixed base 4, and a first gear 7 is mounted on the outer surface of the output end of the first motor 2. The output end of the second motor 3 is connected to a roller 5, which is located on the outer surface of the fixed base 4. A sealing cover 6 is bolted to the feed inlet of the roller 5. A limit seat 10 is connected to one side of the roller 5. A movable rod 11 is connected to the top of the limit seat 10 via a rotating rod. A placement rod 8 is placed inside the fixed base 4, and a limit plate 16 is connected to the outer surface of the placement rod 8. A second gear 9 is mounted on one end of the placement rod 8. The fixed base 4 has an I-shaped cross-section. When grinding the transformer frame, the worker first places multiple transformer frames on the placement rod 8, then inserts one end of the placement rod 8 into the fixing hole 15 and the other end into the groove 14, so that the first gear 7 and the second gear 9 mesh. The fixing seat 4 is rotated, and all the placement rods 8 are installed in sequence. After installation, the grinding sand is put into the inside of the roller 5 and the sealing cover 6 is fixed. At the same time, the first motor 2 and the second motor 3 are started, so that the first motor 2 drives the fixing seat 4 to rotate forward and the second motor 3 drives the drum to rotate in reverse, so that the grinding sand rubs against the transformer frame and grinds the rough edges of the transformer frame through friction.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 5 In the above embodiment, the first gear 7 meshes with the second gear 9. Driven by the first motor 2, the meshing of the first gear 7 and the second gear 9 causes the second gear 9 to rotate the placement rod 8, thereby causing the transformer skeleton on the placement rod 8 to rotate. The rotation increases the contact area between the transformer skeleton and the abrasive, thereby improving the polishing effect of the abrasive on the transformer skeleton.

[0031] See Figure 3 and Figure 5 In the above embodiment, a plurality of grooves 14 are provided on one side of the outer surface of the fixing base 4, and the plurality of grooves 14 are distributed in a circular array. One side of the limiting plate 16 corresponds to the grooves 14. The limiting plate 16 seals the grooves 14, thereby preventing the abrasive from leaking out of the roller 5 from the grooves 14 and causing waste. Since the edges of the transformer frame are irregular and have gaps, the grooves 14 and the limiting plate 16 cooperate to fix the positions of the plurality of placement rods 8, so that the transformer frame on each placement rod 8 will not contact the transformer frame on another placement rod 8, thereby preventing the transformer frames from getting stuck together and causing the grinding to be incomplete.

[0032] See Figure 3 and Figure 5In the above embodiment, the placement rod 8 is detachably connected to the fixing seat 4 through the groove 14. The placement rod 8 is used to fix the transformer skeleton to be ground, so as to avoid the transformer skeleton from directly contacting the roller 5 during grinding. After grinding is completed, the sealing cover 6 is opened and the placement rod 8 is taken out one by one, so that all the transformer skeletons can be taken out, thereby avoiding the situation where the pins of the transformer skeleton are stuck in the gap of the roller 5, which would cause inconvenience in taking them out.

[0033] See Figure 3 and Figure 5 In the above embodiment, a fixing hole 15 is provided on one side of the fixed base 4, and one end of the placement rod 8 is detachably connected to the fixing hole 15. The fixing hole 15 cooperates with the limiting plate 16 to fix the position of the placement rod 8. Driven by the output end of the first motor 2, the first gear 7 meshes with the second gear 9, so that the placement rod 8 rotates while following the rotation of the fixed base 4. The limiting seat 10 cooperates with the groove 14 to fix the placement rod 8, thereby avoiding the displacement of the position of the placement rod 8 under the action of centrifugal force, which would affect the practicality of the device.

[0034] See Figure 1 , Figure 3 and Figure 4 In the above embodiment, both the limiting seat 10 and the movable rod 11 have pin holes 12 on their outer surfaces, and the two pin holes 12 are connected by cotter pins 13. After the placement rods 8 are placed in sequence, the movable rod 11 is rotated so that its pin holes 12 correspond to the pin holes 12 on the limiting seat 10. Then, the cotter pins 13 are inserted into the two pin holes 12 to fix the two pin holes 12. This makes the movable rod 11 and the limiting seat 10 form a whole and cooperates with the groove 14 to fix the placement rods 8, preventing the movement of the placement rods 8 from affecting the meshing of the first gear 7 and the second gear 9.

[0035] See Figure 1 , Figure 3 and Figure 4 In the above embodiment, the movable rod 11 corresponds to the sealing cover 6. When the grinding is finished, the worker first opens the sealing cover 6, then removes the cotter pin 13 and opens the movable rod 11, releasing the limit of one of the placement rods 8, making it convenient for the worker to take all the transformer frames on the placement rod 8. By rotating the fixed base 4, the remaining placement rods 8 are rotated to the position corresponding to the discharge port of the roller 5 and taken out, so that it is not necessary to take out all the transformer frames and grinding sand together and then sort them, thus improving work efficiency.

[0036] See Figure 1 , Figure 3 and Figure 4In the above embodiment, both the limiting seat 10 and the movable rod 11 are arc-shaped. With the cotter pin 13 fixed, the limiting seat 10 and the movable rod 11 are combined into a circular whole and cooperate with the groove 14 to limit the position of the placement rod 8, so as to prevent the placement rod 8 from shifting under the action of centrifugal force. By the arc-shaped setting, this whole is always in contact with the placement rod 8 at only one point, thereby reducing the contact area between the limiting seat 10 and the movable rod 11 and the placement rod 8, and extending the service life of the placement rod 8, the limiting seat 10 and the movable rod 11.

[0037] Example 2: In order to recycle the abrasive, Example 2 is an improvement on Example 1. (See attached document.) Figure 1 and Figure 2 A holding frame 17 is placed between the two mounting bases 1 via a placement plate, and a screen 18 is placed inside the holding frame 17. After the transformer frame is removed, the roller 5 is rotated so that the discharge port of the roller 5 faces downward. Under the action of gravity, the grinding sand and burr debris fall into the collection frame together. The grinding sand is screened by the screen 18 so that the debris and unqualified grinding sand are separated from the qualified grinding sand, and the qualified grinding sand is recycled.

[0038] The implementation principle of this utility model is as follows: When grinding the transformer frame, the worker first places multiple transformer frames to be ground (not shown in the figure, but the specific appearance can be referred to the transformer frame with patent application number 202222207886.X) on multiple placement rods 8. Then, one end of one placement rod 8 is inserted into the fixing hole 15, and the other end is placed into the groove 14, so that the first gear 7 meshes with the second gear 9. The fixing seat 4 is rotated, and all placement rods 8 are installed in sequence. After installation, the movable rod 11 is rotated, and the movable rod 11 and the limiting seat 1 are connected by the cotter pin 13. 0. Fix it to make it a whole and limit the placement rod 8. Finally, put the polishing sand into the inside of the roller 5 and fix the sealing cover 6. At the same time, start the first motor 2 and the second motor 3. The first motor 2 drives the fixed seat 4 to rotate forward and the second motor 3 drives the drum to rotate in reverse, so that the polishing sand and the transformer frame will rub against each other. The friction will polish the rough edges of the transformer frame. After polishing, open the sealing cover 6, remove the cotter pin 13, and rotate the fixed seat 4 in sequence so that the placement rod 8 corresponds to the feed port of the roller 5. Then, take out the placement rod 8 and the polished transformer frame in sequence.
