Description

Technical Field

[0001] This utility model relates to the field of guiding device technology, specifically a positioning and guiding device for small iron core processing. Background Technology

[0002] An iron core is a key component used in electronic and electrical equipment. It is typically made of magnetic materials (such as silicon steel sheets or ferrite) and is used for magnetic conduction and the transmission of concentrated magnetic flux. Iron cores are widely used in devices such as current transformers, inductors, generators, frequency converters, and magnetic sensors. During iron core processing, a stamping press is used to press a coil of material into the desired shape. To facilitate feeding during stamping, a guide frame guides the movement of the coil. A search reveals that Chinese patent CN117533852A discloses an easy-to-use guiding device for feeding iron cores, comprising: at least two bases connected by a first rotation adjustment mechanism, with a bracket fixed on each base; a second guide frame... The device includes a guide rod and a second guide rod arranged side-by-side along the height of the support. One end of the first guide rod is engaged with the support via a clamping mechanism, which presses the first guide rod into contact with the second guide rod. The device is folded and stored conveniently by incorporating a first rotation adjustment mechanism, a first guide section, and a second guide section, avoiding the large external space required for traditional guide frames which are mostly fixed with metal. A scraper is also included to prevent difficulty in cleaning dirt from the coil material during transport and guidance.

[0003] Currently, existing guide devices, due to structural limitations, can only fix iron cores of specific sizes. This fixing method has significant limitations and cannot be applied to a large number of iron cores of different sizes. Utility Model Content

[0004] To address the problem that existing guiding devices are inconvenient for fixing iron cores of different sizes, this utility model provides a positioning and guiding device for small iron core processing.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A positioning and guiding device for small iron core processing includes a guide seat and a base. A cross-shaped hollow groove is formed on one side of the guide seat. A gathering mechanism is provided inside the cross-shaped hollow groove. One end of the gathering mechanism extends to the outside of the cross-shaped hollow groove and is connected to a clamping plate. The gathering mechanism includes a first lead screw, a second lead screw, and a connecting structure for transmission between the two. Slider blocks are threaded to both sides of the outer walls of the first and second lead screws. One end of each slider is connected to a pin for fixing the clamping plate. A moving mechanism is provided inside the base. One side of the moving mechanism is connected to the bottom surface of the guide seat.

[0007] Furthermore, the connection structure includes a worm and a worm wheel, with the worm mounted on the outer wall of the first lead screw and the worm wheel mounted on the outer wall of the second lead screw, the worm wheel meshing with the worm.

[0008] The beneficial effects of adopting the above-mentioned further solution are that, by using the design of worm gear and worm wheel meshing, when the first lead screw rotates, the worm can drive the worm wheel to rotate synchronously, thereby driving the second lead screw to operate, realizing the linkage transmission between the first and second lead screws; the worm gear transmission has the characteristics of stable transmission ratio and strong self-locking, which can not only ensure the synchronicity of the rotation of the two lead screws and ensure the uniformity of the clamping force, but also prevent the lead screw from reversing due to external force during the processing, thus improving the stability and reliability of positioning.

[0009] Furthermore, the clamping plate includes an arc-shaped plate body, and one side of the arc-shaped plate body has an insertion hole that matches the insertion shaft.

[0010] The beneficial effects of adopting the above-mentioned further solution are that the arc-shaped plate of the clamping plate is more compatible with the shape of the small iron core, which can increase the contact area with the iron core, disperse the clamping force, avoid excessive local pressure leading to iron core deformation, and protect the iron core machining accuracy; the insertion hole on the arc-shaped plate matches the insertion shaft of the gathering mechanism, which can quickly realize the connection and disassembly of the clamping plate and the slider, and facilitate the replacement of clamping plates of different sizes according to the specifications of the iron core, thereby improving the adaptability of the device.

[0011] Furthermore, a first motor is mounted on the top surface of the guide seat, and the output end of the first motor is connected to the top end of the first lead screw.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the first motor on the top surface of the guide seat is directly connected to the top of the first lead screw, providing a stable power source for the operation of the gathering mechanism.

[0013] Furthermore, dust-proof cloths are connected to both sides of the inner wall of the cross-shaped hollow groove, and the adjacent ends of the two dust-proof cloths are respectively connected to the two sides of the slider.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the dust cover is connected to the slider and can extend and retract synchronously with the movement of the slider, always blocking the opening of the hollow groove, effectively preventing iron filings, dust and other impurities generated during the processing from entering the guide seat. At the same time, the dust cover does not affect the normal movement of the slider, ensuring the flexible operation of the gathering mechanism and ensuring the stable realization of the positioning and guiding function.

[0015] Furthermore, the dust-proof cloth includes a cloth strip, the outer wall of which is provided with equidistant pleats for shrinkage.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the crease gives the fabric tape good shrinkage and stretching properties, and it can be quickly folded or unfolded as the slider moves, ensuring effective coverage of the cross-shaped cutout groove.

[0017] Furthermore, the moving mechanism includes a sliding plate, which is slidably connected to the interior of the base, and the top surface of the sliding plate is connected to the bottom surface of the guide seat.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the slide plate is slidably connected to the base, and the top surface is fixed to the bottom surface of the guide seat, which can drive the guide seat and the positioning structure above it to move smoothly along the base, thereby realizing the lateral adjustment of the iron core processing position.

[0019] Furthermore, a threaded rod is threadedly connected to one side of the slide plate, and limit rods are inserted into both sides of the slide plate near the threaded rod. A second motor is installed on the outer wall of the base, and the output end of the second motor is connected to one end of the threaded rod for transmission.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the threaded rod on one side of the slide is connected to the second motor, and the motor drives the threaded rod to rotate, which can drive the slide to move smoothly along the limit rod.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This type of small iron core processing positioning and guiding device, through the coordinated use of a gathering mechanism, clamping plates, and a moving mechanism, allows the guiding device to adapt to iron cores of different sizes. Specifically, by setting the gathering mechanism in the cross-shaped hollow groove of the guide seat, a linkage transmission is formed by the first lead screw, the second lead screw, and the connecting structure. With the help of the slider and the insert shaft connected by the thread on the outer wall, the clamping plate can be driven to gather synchronously from multiple directions, achieving precise clamping and positioning of iron cores of different sizes. The moving mechanism in the base can drive the guide seat to move as a whole, which can flexibly adjust the processing position of the iron core to adapt to the needs of different processing procedures. The structural design of the cross-shaped hollow groove provides reasonable space for the movement of the gathering mechanism, making the overall device layout compact. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5This utility model provides a technical solution: a positioning and guiding device for small iron core processing, including a guide seat 1 and a base 6. A cross-shaped perforated groove is provided on one side of the guide seat 1. The structure of the cross-shaped perforated groove provides reasonable space for the movement of the gathering mechanism 2, making the overall device layout compact. The gathering mechanism 2 is located inside the cross-shaped perforated groove. One end of the gathering mechanism 2 extends to the outside of the cross-shaped perforated groove and is connected to a clamping plate 3. The gathering mechanism 2 includes a first lead screw 201, a second lead screw 202, and a connecting structure for transmission between the two. Slider blocks 205 are threadedly connected to both sides of the outer walls of the first lead screw 201 and the second lead screw 202. One end of block 205 is connected to a shaft 206 for fixing clamping plate 3. By setting a gathering mechanism 2 in the cross-shaped hollow groove of guide seat 1, a linkage transmission is formed by the first lead screw 201, the second lead screw 202 and the connecting structure. With the slider 205 and the shaft 206 connected by the outer wall thread, the clamping plate 3 can be driven to gather synchronously from multiple directions to achieve precise clamping and positioning of iron cores of different sizes. The base 6 is provided with a moving mechanism 7. One side of the moving mechanism 7 is connected to the bottom surface of guide seat 1. The moving mechanism 7 in the base 6 can drive the guide seat 1 to move as a whole, and the processing position of the iron core can be flexibly adjusted to meet the needs of different processing procedures.

[0031] As an embodiment of this utility model, the connecting structure further includes a worm 203 and a worm wheel 204. The worm 203 is fitted onto the outer wall of the first lead screw 201, and the worm wheel 204 is fitted onto the outer wall of the second lead screw 202. The worm wheel 204 meshes with the worm 203. With the design of the worm 203 and worm wheel 204 meshing, when the first lead screw 201 rotates, the worm 203 can drive the worm wheel 204 to rotate synchronously, thereby driving the second lead screw 202 to rotate, realizing the linkage transmission between the first lead screw 201 and the second lead screw 202. The worm gear transmission has the characteristics of stable transmission ratio and strong self-locking, which can ensure the synchronicity of the rotation of the two lead screws and ensure that the clamping force of the clamping plate 3 is uniform. The clamping plate 3 is uniform and can prevent the lead screw from reversing due to external force during the processing, thus improving the stability and reliability of positioning. The clamping plate 3 includes an arc-shaped plate 301. One side of the arc-shaped plate 301 is provided with a hole 302 that matches the insertion shaft 206. The arc-shaped plate 301 of the clamping plate 3 has a stronger compatibility with the shape of the small iron core, which can increase the contact area with the iron core, disperse the clamping force, avoid excessive local pressure that could cause the iron core to deform, and protect the processing accuracy of the iron core. The insertion hole 302 on the arc-shaped plate 301 matches the insertion shaft 206 of the gathering mechanism 2, which can quickly realize the connection and disassembly of the clamping plate 3 and the slider 205, and facilitate the replacement of clamping plates 3 of different sizes according to the specifications of the iron core, thus improving the adaptability of the device.

[0032] As an embodiment of this utility model, a first motor 5 is further installed on the top surface of the guide seat 1. The output end of the first motor 5 is connected to the top end of the first lead screw 201. The first motor 5 on the top surface of the guide seat 1 is directly connected to the top end of the first lead screw 201 to provide a stable power source for the operation of the gathering mechanism 2.

[0033] As an embodiment of this utility model, further, dust-proof cloths 4 are connected to both sides of the inner wall of the cross-shaped hollow groove. The adjacent ends of the two dust-proof cloths 4 are connected to both sides of the slider 205. The dust-proof cloths 4 are connected to the slider 205 and can extend and retract synchronously with the movement of the slider 205, always blocking the opening of the hollow groove, effectively preventing iron filings, dust and other impurities generated during the processing from entering the guide seat 1. At the same time, the dust-proof cloths 4 do not affect the normal movement of the slider 205, ensuring the flexible operation of the gathering mechanism 2 and ensuring the stable realization of the positioning and guiding function. The dust-proof cloth 4 includes a cloth strip 401. The outer wall of the cloth strip 401 is provided with equidistant creases 402 for shrinkage. The creases 402 give the cloth strip 401 good shrinkage and extension performance, which can be quickly folded or unfolded with the movement of the slider 205 to ensure effective blocking of the cross-shaped hollow groove.

[0034] As an embodiment of this utility model, the moving mechanism 7 further includes a sliding plate 701, which is slidably connected to the inside of the base 6. The top surface of the sliding plate 701 is connected to the bottom surface of the guide seat 1. The sliding plate 701 is slidably connected to the base 6, and its top surface is fixed to the bottom surface of the guide seat 1. This allows the guide seat 1 and the positioning structure above it to move smoothly along the base 6, thereby achieving lateral adjustment of the core processing position. A threaded rod 703 is threadedly connected to one side of the sliding plate 701. Limiting rods 702 are inserted into both sides of the sliding plate 701 near the threaded rod 703. A second motor 704 is installed on the outer wall of the base 6. The output end of the second motor 704 is drivenly connected to one end of the threaded rod 703. The threaded rod 703 on one side of the sliding plate 701 is drivenly connected to the second motor 704. The motor drives the threaded rod to rotate, which can drive the sliding plate 701 to move smoothly along the limiting rod 702.

[0035] Specifically, the working principle of this positioning and guiding device for small iron core processing is as follows: When in use, the small iron core to be processed is placed below the cross-shaped hollow groove of the guide seat 1, and the first motor 5 on the top surface of the guide seat 1 is started. The output end of the first motor 5 drives the first lead screw 201 of the gathering mechanism 2 to rotate. Since the worm 203 mounted on the outer wall of the first lead screw 201 meshes with the worm wheel 204 on the outer wall of the second lead screw 202, the rotation of the first lead screw 201 will drive the worm wheel 204 to rotate synchronously, thereby driving the second lead screw 202 to operate, realizing the linkage transmission of the two lead screws. When the first lead screw 201 and the second lead screw 202 rotate, the sliders 205 connected by threads on both sides of their outer walls will move along the lead screw axis. The insertion shaft 206 at one end of the slider 205 drives the clamping plate 3 to move synchronously. Since the arc-shaped plate 301 of the clamping plate 3 is fixed to the insertion shaft 206 through the insertion hole 302, the four clamping plates 3 will converge synchronously from multiple directions until they fit against the outer wall of the iron core. The arc-shaped plate increases the contact area and disperses the clamping force, so as to achieve precise clamping and positioning of iron cores of different sizes and avoid processing deviation. During the clamping and positioning process, the dust cover 4 on both sides of the inner wall of the cross-shaped hollow groove moves and extends synchronously with the slider 205. The crease 402 on the outer wall of the cloth strip 401 ensures that it folds or unfolds smoothly, always blocking the opening of the hollow groove, preventing iron filings and dust from entering the guide seat 1, and protecting the normal operation of the transmission components. If the core processing position needs to be adjusted, the second motor 704 on the outer wall of the base 6 is started. The second motor 704 drives the threaded rod 703 of the moving mechanism 7 to rotate. The slide plate 701, which is threadedly connected to the threaded rod 703, will slide smoothly along the limit rods 702 on both sides. Since the top surface of the slide plate 701 is fixed to the bottom surface of the guide seat 1, when the slide plate moves, it will drive the guide seat 1 and the core that has been positioned above to move synchronously, so as to realize the lateral adjustment of the core processing position, adapt to the needs of different processing procedures, and finally complete the positioning and guiding operation of the core processing.
