Description

Technical Field

[0001] The invention relates to the technical field of transformer magnetic cores, and more specifically, to a processing device for transformer magnetic cores. Background Art

[0002] The transformer is mainly composed of a wire wrap and a magnetic core. There are many types of transformers, including a complete transformer core composed of two ferrite cores. Before use, in order to control the inductance, it is usually necessary to grind the center column of the core to a certain depth so that the contact surfaces of the two ferrite cores can fit tightly when combined to improve the inductance stability value.

[0003] The prior art usually uses manual grinding or machine grinding to grind the magnetic core. Among them, manual grinding usually involves holding a single magnetic core and grinding with a file, or holding a magnetic core with both hands, sticking the middle columns of the two magnetic cores together for grinding, and grinding off the middle columns of the magnetic cores to a certain depth. Machine grinding usually fixes a single or multiple magnetic cores and then grinds them with a file or a grinding wheel.

[0004] Although the above two grinding methods can complete the grinding work of the core column well, in the actual operation process, manual grinding is difficult to control the grinding accuracy due to the increased vibration of human hands after long-term work, which can easily lead to over-deep or over-shallow grinding. The file or grinding wheel in machine grinding is prone to wear and tear that is not easily noticeable to the naked eye after being used for a period of time, which can easily affect the grinding accuracy. In addition, the grinding force of the file or grinding wheel is relatively large, which requires high fixation of the core and is more difficult to disassemble and assemble, all of which have certain inconveniences.

DETAILED DESCRIPTION

[0019] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0020] like Figure 1-Figure 11 As shown, this embodiment provides a transformer core processing device, including: a base 100; The mounting part 200 is arranged on the base 100. The mounting part 200 includes a mounting plate 201 movably arranged on the base 100. The mounting plate 201 is provided with a slot 1 for transversely embedding a plurality of magnetic cores. The base 100 is provided with a first moving component for driving the mounting plate 201 to reciprocate along its own length direction. The second mounting part 300 is arranged on the base 100. The second mounting part 300 includes a support frame 301 fixedly connected to the base 100. A second mounting plate 302 is arranged above the first mounting plate 201. A second moving component is arranged on the support frame 301 for driving the second mounting plate 302 to reciprocate in the vertical reverse direction. A plurality of second card slots for vertically embedding magnetic cores are equidistantly provided on the second mounting plate 302. The number of the second card slots corresponds to the number of magnetic cores embedded on the first mounting plate 201. An anti-slipping member is slidably provided on the second mounting plate 302. The anti-slipping member includes a pair of parallel slide plates 303 and a plurality of anti-slipping plates 304. Each anti-slipping plate 304 is equidistantly installed between the two slide plates 303, and the number of the anti-slipping plates 304 corresponds to the number of the second card slots. The third moving assembly 400 is disposed on the second mounting plate 302, and when the first mounting plate 201 moves downward, the third moving assembly 400 drives the anti-slip component to move toward the direction close to the second card slot, so as to block the upper notch of the second card slot.

[0021] The working principle and beneficial effects of the above technical solution are: First, half of the multiple groups of magnetic cores to be polished are embedded one by one into the first slot on the first mounting plate 201 , and then the other half of the magnetic cores are embedded one by one into the second slot on the second mounting plate 302 .

[0022] Next, the second moving component drives the second mounting plate 302 to move downward. During the downward movement of the second mounting plate 302, the third moving component 400 is driven to operate. The third moving component 400 drives the slide plate 303 and the anti-slip plate 304 to move toward the direction close to the second card slot until the anti-slip plate 304 just slides to the top of the corresponding magnetic core, blocking the space for its upward movement. At this time, the middle columns of the magnetic cores on the first mounting plate 201 and the second mounting plate 302 are against each other one by one, and the magnetic cores in each card slot two are vertically crossed with the corresponding magnetic cores in the first card slot.

[0023] Finally, the first moving assembly is used to drive the mounting plate 1 201 to move back and forth along its own length direction, so that the middle columns of the magnetic cores in groups of two rub against each other and their surfaces are polished and smoothed.

[0024] After polishing is completed, the second moving component is used to drive the second mounting plate 302 to move upward. During this process, the third moving component 400 drives the anti-drop plate 304 to reset, so that the staff can take out the polished magnetic cores in the second and first slots, and then install the magnetic cores to be polished, and repeat the above process.

[0025] The present embodiment adopts the technical means of matching the mounting part 1 200 and the mounting part 2 300, and utilizes the symmetry of the ferrite core itself. Through the mutually perpendicular slots 1 and 2, multiple pairs of ferrite cores are grouped together in pairs and perpendicularly fitted together for polishing, thereby avoiding the instability of manual polishing and the loss problem of machine polishing, overcoming the shortcomings of the prior art, and improving the stability of the device. At the same time, the third movable component 400 is used to automatically fix the core when the mounting plate 2 moves down, making it easier to disassemble and assemble, thereby improving the practicality of the present device.

[0026] like Figure 3 to Figure 4 As shown, in a specific embodiment: a U-shaped plate 305 corresponding in number to the anti-slip plate 304 is fixedly connected between the two slide plates 303, a plurality of symmetrically arranged spring telescopic rods 306 are fixedly connected to the inner top of each U-shaped plate 305, the lower end of the spring telescopic rod 306 is fixedly connected to the upper surface of the corresponding anti-slip plate 304, the width of the U-shaped plate 305 is equal to the width of the anti-slip plate 304, and the width of the anti-slip plate 304 is smaller than the width of the second card slot.

[0027] The working principle and beneficial effects of the above technical solution are as follows: the setting of the spring telescopic rod 306 enables each group of magnetic cores to be tightly pressed together under the elastic force of the spring telescopic rod 306, thereby avoiding the situation where the middle column of the shorter magnetic core is difficult to be polished due to the error in the actual production of the middle column length of each group of magnetic cores during polishing.

[0028] like Figure 2As shown, in a specific embodiment: the first moving component includes a reciprocating screw 202 rotatably connected to the base 100, a servo motor 203 is fixedly connected to the base 100, the output shaft of the servo motor 203 is fixedly connected to the reciprocating screw 202, a mounting block 204 is fixedly connected to the lower side of the mounting plate 201, the reciprocating screw 202 is threadedly connected to the mounting block 204, a pair of parallel limit rods 205 are fixedly connected to the base 100, a pair of mounting blocks 206 are fixedly connected on both sides of the mounting plate 201, and each mounting block 206 is slidably connected to the corresponding limit rod 205.

[0029] The working principle and beneficial effects of the above technical solution are as follows: the servo motor 203 is started, and the output shaft of the servo motor 203 rotates, driving the reciprocating screw rod 202 to rotate, thereby driving the mounting block 204, the mounting plate 201 and multiple mounting blocks 206 to move synchronously, so that the mounting block 206 and the corresponding limit rod 1 205 slide relative to each other, and at the same time, the limit rod 1 205 limits the movement trajectory of the mounting block 206, the mounting block 1 204 and the mounting plate 1 201, so that they can only reciprocate in the horizontal direction.

[0030] like Figure 3 As shown, in a specific embodiment: the second moving component includes an electric telescopic rod 307 fixedly connected to the support frame 301, and the moving end of the electric telescopic rod 307 is fixedly installed with a connecting plate 308, and the lower surface of the connecting plate 308 is fixedly connected to the upper surface of the mounting plate 302.

[0031] The working principle and beneficial effects of the above technical solution are as follows: the electric telescopic rod 307 is started, and the output shaft of the electric telescopic rod 307 moves, driving the connecting plate 308 and the mounting plate 302 to move in the vertical direction.

[0032] like Figure 5 As shown, in a specific embodiment: the third moving component 400 includes a rotatably arranged horizontal axis 401, a pair of horizontal plates 402 are fixedly connected to the mounting plate 302, each horizontal plate 402 is rotatably connected to the horizontal axis 401, a gear 1 403 is fixedly connected to the middle part of the horizontal axis 401, a rack 1 404 is fixedly connected to the support frame 301, the gear 1 403 is meshingly connected to the rack 1 404, both ends of the horizontal axis 401 are fixedly connected to gear 2 405, each slide plate 303 is fixedly connected to a rack 2 406 on one side close to the gear 2 405, and the rack 2 406 is meshingly connected to the corresponding gear 2 405.

[0033] The working principle and beneficial effects of the above technical solution are as follows: when the mounting plate 302 moves downward, the rack 404 drives the gear 403 to rotate, thereby driving the horizontal axis 401 to rotate synchronously. The rotation of the horizontal axis 401 drives the gear 2 405 at both ends to rotate, thereby driving the corresponding rack 2 406 to move. The rack 2 406 drives the corresponding slide plate 303 and the anti-slip plate 304 thereon to move, so that multiple anti-slip plates 304 all move in the direction close to the corresponding slot 2 until they move to the top of the corresponding magnetic core and fix it in the mounting plate 302.

[0034] like Figure 6 , Figure 7 , Fig.11 As shown, in a specific embodiment: a pop-up assembly 500 is also provided on the second mounting plate 302, and the pop-up assembly 500 includes a moving frame 501 slidably connected in the second mounting plate 302, and a spring 1 502 is fixedly connected to the side of the moving frame 501 away from the second rack 406, and the other end of the spring 1 502 is fixedly connected to the inner wall of the second mounting plate 302, and a slide groove for the moving frame 501 to move is provided in the second mounting plate 302, and each moving frame 501 is fixedly connected with a number of clamping rods 503 corresponding to the second clamping slot, and the second mounting plate 302 is located in the plate body of the second clamping slot. A pair of push rods 504 are provided on the upper slide, and the lower end of each push rod 504 is fixedly connected to a spring 2 505, and the lower end of the spring 2 505 is fixedly connected to the inner bottom of the mounting plate 2 302, and each clamping rod 503 has a convex portion at one end close to the push rod 504, and a circular groove for the clamping rod 503 to be embedded is provided at the corresponding position on the push rod 504, and a force-bearing plate 506 is fixedly connected to one side of each movable frame 501 close to the rack 2 406, and a pair of extrusion plates 507 are fixedly connected to the horizontal axis 401, and each extrusion plate 507 is in contact with and cooperates with the corresponding force-bearing plate 506.

[0035] The working principle and beneficial effects of the above technical solution are as follows: in the initial state, the extrusion plate 507 squeezes the corresponding force-bearing plate 506, so that the convex parts on the multiple clamping rods 503 are in a state of being separated from the corresponding circular grooves, the spring 1 502 is deformed, and the push rod 504 is supported by the spring 2 505, and most of the rod bodies pop out. When it is needed, the mounting plate 2 302 is first moved downward for a distance, so that the horizontal axis 401 rotates, driving the two extrusion plates 507 to move away from the force-bearing plate 506 until it moves to a position where it is against the force-bearing plate 506 but not subjected to force. At this time, the moving frame 501 moves under the elastic force of the spring 1 502, driving the multiple clamping rods 503 to move in the direction close to the corresponding push rod 504, until the clamping rod 503 and the corresponding push rod 504 are against each other and subjected to force. At this time, the magnetic core is placed in the corresponding slot 2 and pressed down with force. During the downward movement of the magnetic core, the push rod 504 is pressed down until the push rod The circular groove on 504 moves to a position exactly opposite to the convex portion on the clamping rod 503, and the spring second 505 is compressed. The convex portion is embedded in the corresponding circular groove under the elastic force of the spring first 502, locking the push rod 504. During the downward movement of the mounting plate second 302, the squeezing plate 507 moves in the direction away from the force-bearing plate 506, and the locking state of the push rod 504 is not released. After the grinding is completed, the mounting plate second 302 moves upward, and the squeezing plate 507 rotates in the direction close to the force-bearing plate 506 until it contacts and squeezes the force-bearing plate 506, pushing the force-bearing plate 506 in the direction close to the mounting plate second 302, thereby driving the movable frame 501 and the clamping rod 503 thereon to move, so that the convex portion on the clamping rod 503 is disengaged from the corresponding circular groove, and the push rod 504 moves upward under the elastic force of the corresponding spring second 505, pushing part of the core of the corresponding magnetic core out of the clamping groove second, making it convenient for the staff to take out the magnetic core.

[0036] like Figure 6 As shown, in a specific embodiment: a plurality of symmetrically arranged mounting blocks 3 508 are fixedly connected to the mounting plate 2 302 , a plurality of limiting rods 2 509 are fixedly connected to the base 100 , and each limiting rod 2 509 is slidably connected to the corresponding mounting block 3 508 .

[0037] The working principle and beneficial effects of the above technical solution are as follows: when the mounting plate 2 302 moves up and down, it drives multiple mounting blocks 3 508 and corresponding limiting rods 2 509 to slide relative to each other. At the same time, the setting of the limiting rods 2 509 makes the mounting plate 2 302 more stable when moving in the vertical direction and during grinding.

[0038] like Figure 8 , Fig. 9As shown, in a specific embodiment: a fastening assembly 600 is arranged on the mounting plate 201, and the fastening assembly 600 includes a threaded rod 601 rotatably arranged on the mounting plate 201, a fastening plate 602 is slidably arranged in a slot, one end of the threaded rod 601 located in the slot is rotatably connected to the fastening plate 602, and one end of the threaded rod 601 located outside the mounting plate 201 is fixedly connected to a rotating disk 603, and the rotating disk 603 is provided with anti-slip grooves.

[0039] The working principle and beneficial effects of the above technical solution are as follows: applying a force on the rotating disk 603 drives the threaded rod 601 to rotate, thereby driving the fastening plate 602 to move. The fastening plate 602 is restricted in its movement trajectory by the slot 1, and moves toward the direction of the magnetic core in the slot 1 until the fastening plate 602 tightly presses against the nearest magnetic core, which can further fix the magnetic core in the slot 1 and improve its stability during grinding.

[0040] like Figure 8 , Fig. 9 As shown, in a specific embodiment: a positioning rod 604 is slidably connected to the rotating disk 603, and a positioning groove for the positioning rod 604 to be inserted is opened on the mounting plate 201.

[0041] The working principle and beneficial effects of the above technical solution are as follows: after the fastening plate 602 holds the magnetic core against the magnetic core, the positioning rod 604 is rotated to a position exactly opposite to the positioning groove, and a force is applied to the positioning rod 604 to insert it into the positioning groove and fix the rotating disk 603, thereby preventing the fastening plate 602 from shifting during grinding and improving the stability of the device.

[0042] like Fig.10 As shown, in a specific embodiment: a receiving groove 101 is opened in the base 100, and a plurality of drainage holes 102 are opened through the bottom of the mounting plate 201.

[0043] The working principle and beneficial effects of the above technical solution are: The receiving groove 101 on the base 100 is filled with water, and the magnetic core being polished is flushed with water at regular intervals to cool it down and wash away the debris generated by polishing. The drainage hole 102 can drain the water entering the card slot one.

[0044] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.
