Description

Technical Field

[0001] This application relates to the field of magnetic pole preparation tooling technology, and more specifically, to a magnetic pole winding clamping device. Background Technology

[0002] The magnetic poles of high-speed maglev vehicles are the core components of the high-speed maglev transportation system, greatly affecting the performance of the maglev vehicles. During the manufacturing process of the magnetic poles, hundreds of turns of thin aluminum foil need to be wound around the surface of the iron core. After the aluminum foil is wound, the magnetic poles need to be heated and cured in a heating furnace until the heating and cooling curing is completed. After the hundreds of turns of aluminum foil are wound, they are prone to unraveling due to the tension of the material itself, whether during the transfer to the heating furnace or during the curing process. If they are not clamped and fixed, they are prone to collapse as a whole, which will have an adverse effect on the quality of the magnetic poles.

[0003] In summary, how to avoid the aluminum foil becoming loose during the manufacturing process of magnetic poles is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The core of this application is to provide a magnetic pole winding clamping device, which can prevent the aluminum foil wound around the magnetic pole from loosening.

[0045] This application provides a magnetic pole winding clamping device for clamping and fixing products. The magnetic pole winding clamping device includes: a first clamp 11, a second clamp 12, and a connecting component 2; both the first clamp 11 and the second clamp 12 are concave structures, and the concave sides of the first clamp 11 and the second clamp 12 are arranged opposite to each other for clamping the product located between them; the first ends of the first clamp 11 and the second clamp 12 that are close to each other and the second ends that are close to each other are movably connected by the corresponding connecting component 2.

[0046] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4As explained, both the first clamp 11 and the second clamp 12 are concave structures with a groove on one side, such as C-shaped, L-shaped, or U-shaped components. The configurations of the first clamp 11 and the second clamp 12 can be the same or different. To accommodate the product, the openings of the first clamp 11 and the second clamp 12 are positioned opposite each other, so their grooves each accommodate a portion of the product, such as half or one-third. To achieve clamping and fix the product's position, a [feature / feature] is provided on the upper left end of each of the first clamp 11 and the second clamp 12 near each other. A connecting component 2 is provided, and a connecting component 2 is also provided at the lower right end of the first clamp 11 and the second clamp 12 that are close to each other. This fixes the relative position of the clamping device and the product. The connecting component 2 allows the close ends of the first clamp 11 and the second clamp 12 to be tightly connected to clamp the product. Conversely, it can also be slightly loosened or disengaged so that the close ends of the first clamp 11 and the second clamp 12 can be moved away from each other to release the product. Thus, the magnetic pole winding clamping device can clamp the magnetic pole to prevent the aluminum foil wound around the magnetic pole from loosening.

[0047] Based on the above embodiments, both the first clamp 11 and the second clamp 12 have a first clamping arm 101 and a second clamping arm 102, and there is a non-zero included angle between the first clamping arm 101 and the second clamping arm 102 of the first clamp 11 and between the first clamping arm 101 and the second clamping arm 102 of the second clamp 12.

[0048] refer to Figure 1 As explained, both the first clamp 11 and the second clamp 12 are composed of two parts, namely the first clamping arm 101 and the second clamping arm 102. The ends of the first clamping arm 101 and the second clamping arm 102 that are close to each other in the first clamp 11 are fixedly connected. The ends of the first clamping arm 101 and the second clamping arm 102 that are close to each other in the second clamp 12 are also fixedly connected. The ends of the first clamping arm 101 and the second clamping arm 102 that are far apart in the first clamp 11 are connected to the corresponding ends of the first clamping arm 101 and the second clamping arm 102 that are far apart in the second clamp 12. Thus, the first clamp 11 and the second clamp 12 can form a quadrilateral cavity, such as a square cavity, a parallelogram cavity, a trapezoidal cavity, etc.

[0049] It should be noted that the included angle between the first clamping arm 101 and the second clamping arm 102 in the first clamp 11 and the included angle between the first clamping arm 101 and the second clamping arm 102 in the second clamp 12 may be equal or unequal.

[0050] Based on the above embodiments, protective pads 3 are provided on the inner side of the first clamping arm 101 and the inner side of the second clamping arm 102 to prevent damage to the product.

[0051] Reference image Figure 1 , Figure 2 , Figure 3 , Figure 4 As can be seen, protective pads 3 are provided on the inner sides of all four side walls of the clamping device. When using the clamping device to hold the product, the product is in direct contact with the protective pads 3. The protective pads 3 can be made of rubber or polytetrafluoroethylene, etc., to prevent damage to the product that may be caused when using the clamping device to hold the product.

[0052] Preferably, the protective pad 3 is a flexible pad with high rigidity to ensure that the magnetic pole size meets the design requirements and also meets the clamping requirements.

[0053] Based on the above embodiments, the protective pad 3 has several countersunk holes, and the first clamping arm 101 and the second clamping arm 102 each have several fixing holes; the protective pad 3 is fixed to the first clamping arm 101 or the second clamping arm 102 by several first threaded rods 4, and the several first threaded rods 4 are inserted into the countersunk holes and fixing holes extending along the same axis, and the tail end of the first threaded rod 4 is buried inside the countersunk hole.

[0054] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 To fix the protective pad 3, countersunk holes extending along its thickness are provided on the protective pad 3, and the number of countersunk holes on a single pad is greater than or equal to two. Correspondingly, fixing holes are provided at corresponding positions of the first clamping arm 101 and the second clamping arm 102 of the first clamp 11 and the second clamp 12. The head end of the first threaded rod 4 is close to the protruding side of the first clamp 11 or the second clamp 12, while the tail end is submerged in the countersunk hole, so that the first threaded rod 4 will not come into contact with the clamped product, thus preventing damage to the product.

[0055] refer to Figure 3 , Figure 4 As can be seen, based on the above embodiments, the first clamping arm 101 and the second clamping arm 102 of the first clamp 11 and the second clamping arm 12 are both C-shaped channel steels. The lower left ends of the first clamping arm 101 and the second clamping arm 102 in the first clamp 11 are connected and welded together, while the lower right ends of the first clamping arm 101 and the second clamping arm 102 in the second clamp 12 are connected and welded together.

[0056] Based on the above embodiments, the first end of the first chuck 11 has a first connecting corner block 111, and the second end of the first chuck 11 has a second connecting corner block 112; the first end of the second chuck 12 has a third connecting corner block 121, and the second end of the second chuck 12 has a fourth connecting corner block 122; the first connecting corner block 111, the second connecting corner block 112, the third connecting corner block 121, and the fourth connecting corner block 122 all have receiving through holes; the receiving through holes of the first connecting corner block 111 and the third connecting corner block 121 extend coaxially; the receiving through holes of the second connecting corner block 112 and the fourth connecting corner block 122 extend coaxially.

[0057] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As can be explained, the corner blocks can be block structures such as triangular prisms or right trapezoidal prisms. A first connecting corner block 111 is set on the convex or concave side of the upper left end of the first clamp 11. Correspondingly, a third connecting corner block 121 is set on the convex or concave side of the upper left end of the second clamp 12. Similarly, a second connecting corner block 112 is set on the convex or concave side of the lower right end of the first clamp 11. Correspondingly, a fourth connecting corner block 122 is set on the convex or concave side of the lower right end of the second clamp 12.

[0058] After the first chuck 11 and the second chuck 12 are positioned with their concave sides facing each other, the receiving through holes of the first connecting corner block 111 and the third connecting corner block 121 extend coaxially, and the receiving through holes of the second connecting corner block 112 and the fourth connecting corner block 122 extend coaxially. By inserting connecting rods into the receiving through holes of the first connecting corner block 111 and the third connecting corner block 121, and by inserting connecting rods into the receiving through holes of the second connecting corner block 112 and the fourth connecting corner block 122, the first chuck 11 and the second chuck 12 can be movably connected. The connecting rods can be pins or spiral shafts, etc.

[0059] It should be noted that the number of the first connecting corner block 111, the second connecting corner block 112, the third connecting corner block 121, and the fourth connecting corner block 122 is not limited, as long as it can meet the requirement of fixing the first clamp 11 and the second clamp 12. For example, the number of the first connecting corner block 111 and the number of the third connecting corner block 121 are greater than or equal to two, and several first connecting corner blocks 111 are arranged along the thickness direction of the first clamp 11, and several third connecting corner blocks 121 are arranged along the thickness direction of the second clamp 12. The number and arrangement of the second connecting corner block 112 and the fourth connecting corner block 122 can be the same as the first connecting corner block 111 and the third connecting corner block 121, or they can be different. For example, the number of the second connecting corner block 112 and the number of the fourth connecting corner block 122 are both one.

[0060] Based on the above embodiments, the first clamping arm 101 of the first clamp 11 is perpendicular to its own second clamping arm 102, and the first clamping arm 101 of the second clamp 12 is perpendicular to its own second clamping arm 102; the receiving through holes of the first end of the first clamp 11 and the first end of the second clamp 12, and the receiving through holes of the second end of the first clamp 11 and the second end of the second clamp 12 are parallel to each other.

[0061] refer to Figure 1 , Figure 2 As explained, the first clamping arm 101 of the first clamp 11 and the second clamp 12 are perpendicular to the second clamping arm 102, that is, both are L-shaped components. In order to achieve clamping of a series of rectangular products of different sizes but the same length-to-width ratio, the accommodating through hole of the first connecting corner block 111 is parallel to the accommodating through hole of the third connecting corner block 121 which is coaxial, and the accommodating through hole of the second connecting corner block 112 which is coaxial with the accommodating through hole of the fourth connecting corner block 122 which is coaxial. That is, all the accommodating through holes extend in the same direction, so that the first clamp 11 and / or the second clamp 12 can be pulled to move along the extension direction of the accommodating through hole, that is, the size of the space formed by the first clamp 11 and the second clamp 12 can be adjusted.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, the extension direction of the accommodating through hole has a 45-degree angle with both the first clamping arm 101 and the second clamping arm 102, so the clamping device in this embodiment is suitable for clamping square products.

[0063] In some embodiments, the extending direction of the accommodating through hole has an angle of 37 degrees with the first clamping arm 101 and an angle of 53 degrees with the second clamping arm 102. In this embodiment, the clamping device is suitable for clamping rectangular products with an aspect ratio of 4:3.

[0064] Of course, the extension direction of the accommodating through hole is not limited to the several examples mentioned above, as long as it meets the clamping requirements of the above-mentioned series of products.

[0065] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As can be seen, in order to achieve the connection between the first chuck 11 and the second chuck 12, based on the above embodiment, the clamping device is also equipped with a plurality of second threaded rods 21, which pass through two corresponding and coaxially extended receiving through holes.

[0066] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the second threaded rod 21 is a bolt, and the connecting assembly 2 also includes several nuts 22. The nuts 22 can be threadedly connected to the head end of the corresponding second threaded rod 21, and the tail ends of the several second threaded rods 21 abut against the corresponding connecting corner blocks. The corresponding connecting corner blocks are the first connecting corner block 111, the second connecting corner block 112, the third connecting corner block 121, or the fourth connecting corner block 122.

[0067] Of course, the connecting component 2 is not limited to the type that includes the second threaded rod 21. For example, the connecting component 2 includes a first magnetic pole and a second magnetic pole. The first magnetic pole is disposed at the end of the first chuck 11 and the second magnetic pole is disposed at the end of the second chuck 12. The ends of the first chuck 11 and the second chuck 12 that are close to each other are connected by the first magnetic pole and the second magnetic pole that attract each other. When it is necessary to remove the product, a pulling force greater than the attraction between the first magnetic pole and the second magnetic pole is applied to the first chuck 11 and the second chuck 12, which can separate the first chuck 11 and the second chuck 12.

[0068] Based on the above embodiments, the second threaded rod 21 has a first threaded rod segment and a second threaded rod segment, and the external thread direction of the first threaded rod segment is opposite to that of the external thread direction of the second threaded rod segment; the first threaded rod segment and the second threaded rod segment of the same second threaded rod 21 are respectively inserted into the receiving through holes at the close ends of the first chuck 11 and the second chuck 12.

[0069] refer to Figure 6As explained, the inner walls of the receiving through holes of the first chuck 11 and the second chuck 12 are machined with internal threads for threaded engagement with the second threaded rod 21. The left-hand portion of the second threaded rod 21, which is inserted into the receiving through hole of the second chuck 12 along its own extension direction, is the first threaded rod segment, and the right-hand portion of the second threaded rod 21, which is inserted into the receiving through hole of the second chuck 12, is the second threaded rod segment. Since the direction of the external thread of the first threaded rod segment is opposite to the direction of the external thread of the second threaded rod segment, the first threaded rod segment and the second threaded rod segment can drive the first chuck 11 and the second chuck 12 to move synchronously towards or away from each other by rotating in the same direction around the center line of their receiving through holes.

[0070] refer to Figure 6 As can be seen, based on the above embodiment, a third driving component 5 is also included. The third driving component 5 is connected to the second threaded rod 21 and is used to drive the second threaded rod 21 to rotate around the center line of the accommodating through hole.

[0071] Specifically, in some embodiments, the third drive assembly 5 is located between the first threaded rod segment and the second threaded rod segment, and the third drive assembly 5 is a dual-axis micro motor. The first output end of the third drive assembly 5 is driven to the first threaded rod segment to drive the first threaded rod segment to rotate around the center line of the accommodating through hole. The second output end is driven to the second threaded rod segment to drive the second threaded rod segment to rotate around the center line of the accommodating through hole. In use, the first threaded rod segment and the second threaded rod segment are controlled to rotate in the same direction by the third drive assembly 5, that is, the first chuck 11 and the second chuck 12 can be driven to move towards or away from each other along the extension direction of the accommodating through hole.

[0072] In other embodiments, such as Figure 6 As shown, the first threaded rod segment and the second threaded rod segment are connected as a single structure. The third drive assembly 5 has an output end, and the output end of the third drive assembly 5 is connected to the free end of the first threaded rod segment or the second threaded rod segment. It is used to drive the second threaded rod 21 to rotate around the center line of the accommodating through hole. When the second threaded rod 21 is driven to rotate by the third drive assembly 5, that is, when the first threaded rod segment and the second threaded rod segment are driven to rotate synchronously, the first chuck 11 and the second chuck 12 can be driven to move towards or away from each other along the extension direction of the accommodating through hole.

[0073] Of course, the type and arrangement of the third drive component 5 are not limited to the type in the above example embodiment, as long as they satisfy the requirement of driving the first threaded rod 4 and the second threaded rod 21 to rotate in the same direction or in reverse.

[0074] Based on the above embodiments, the output end of the third drive component 5 is detachably connected to the second threaded rod 21 through the first movable connection part. The second movable connection part is similar to the first movable connection part, and the second movable connection part may be the same as or different from the first movable connection part.

[0075] Based on the above embodiments, a first driving component 61 and a second driving component 62 are also included; the output end of the first driving component 61 is connected to the first chuck 11, and the output end of the second driving component 62 is connected to the second chuck 12, for driving the first chuck 11 and the second chuck 12 to move toward or away from each other.

[0076] refer to Figure 7 As explained, the clamping device is equipped with a first drive assembly 61 and a second drive assembly 62 that are independent of each other. The output end of the first drive assembly 61 is connected to the first chuck 11 by means of coupling or welding, so that the first chuck 11 can be driven to move towards the side closer to or away from the second chuck 12 along the extension direction of the second threaded rod 21. Similarly, the output end of the second drive assembly 62 is connected to the second chuck 12 by means of coupling or welding, so that the second chuck 12 can be driven to move towards the side closer to or away from the first chuck 11 along the extension direction of the second threaded rod 21, thereby realizing the adjustment of the size of the space formed between the first chuck 11 and the second chuck 12.

[0077] In coordination, to prevent the first drive assembly 61 and the second drive assembly 62 from driving the chuck to move, such as Figure 7 As shown, the connecting component 2 may include springs and / or guide rods, etc., to assist the movement of the first chuck 11 and the second chuck 12.

[0078] In some embodiments, the first drive component 61 stops working, while the second drive component 62 starts to drive only the second chuck 12 to move.

[0079] In some embodiments, the first drive component 61 is activated while the second drive component 62 is deactivated, so that only the first chuck 11 is moved.

[0080] In some embodiments, the first drive component 61 and the second drive component 62 are activated synchronously to drive the first chuck 11 and the second chuck 12 to move simultaneously, and both the first chuck 11 and the second chuck 12 move toward the side away from or toward the side closer to the other.

[0081] It should also be noted that the types of the first drive component 61 and the second drive component 62 are not limited, as long as they can output linear motion. For example, the first drive component 61 and the second drive component 62 can be... Figure 7The electric telescopic pole shown, or the first drive assembly 61 and the second drive assembly 62 may include a motor, a gear and a rack, with the gear fixedly connected to the output end of the motor, and the rack meshing with the gear for transmission.

[0082] Based on the above embodiments, the output ends of the first driving component 61 and the second driving component 62 are both provided with a first movable connection portion. The first driving component 61 is driven to the first chuck 11 through the first movable connection portion, and the second driving component 62 is driven to the second chuck 12 through the first movable connection portion. The first movable connection portion can be detachably connected to the first chuck 11 or the second chuck 12. The first movable connection portion can be an electromagnet or a snap-fit ​​terminal, etc. After clamping the product, the first chuck 11 can be separated from the first driving component 61, and the second chuck 12 can be separated from the second driving component 62 to avoid affecting the subsequent heating and curing process.

[0083] It should be noted that the embodiments of setting the first drive component 61 and / or the second drive component 62, and the embodiments of setting the third drive component 5, can be selected to set one of the embodiments, or both embodiments can be set simultaneously. When both embodiments are set simultaneously, the second threaded rod 21 has a guide rod segment. For example, both ends of the second threaded rod 21 have guide rod segments. That is, along the length direction of the second threaded rod 21, the guide rod segment, the first threaded rod segment, the second threaded rod segment, and another guide rod segment are arranged in sequence. Then, after using the first threaded rod segment and the second threaded rod 21 segment in conjunction with the third drive component 5 to control the first chuck 11 and the second chuck 12 to move away from each other to the limit position of the threaded rod segment, the moving away from each other continues under the guidance of the guide rod segments at both ends and under the drive of the first drive component 61 and / or the second drive component 62. This is beneficial to expanding the size range of products that the clamping device can clamp. Of course, the guide rod segment is not limited to being located at both ends of the second threaded rod 21; it can also be located in the middle of the length, such as between the first and second threaded rod segments. In this case, the third drive assembly 5 drives the first and second chucks to move towards each other to the limit position of the threaded rod segment. Under the guidance of the guide rod segment and the drive of the first drive assembly 61 and / or the second drive assembly 62, they continue to move towards each other, which helps to expand the size range of products that the clamping device can hold. Furthermore, the first threaded rod segment, the second threaded rod segment, and the guide rod segment can be arranged alternately. For example, along the length direction of the second threaded rod 21, the sequence is: guide rod segment, first threaded rod segment, guide rod segment, first threaded rod segment, guide rod segment, second threaded rod segment, guide rod segment, second threaded rod segment, guide rod segment.

[0084] Furthermore, in embodiments where a third driving component 5, a first driving component 61, and / or a second driving component 62 are simultaneously provided, it should be further explained that, in order to prevent the output ends of the first driving component 61 and the second driving component 62 from affecting the function of the third driving component 5 in driving the first chuck 11 and the second chuck 12, in specific embodiments, the output ends of the first driving component 61 and the second driving component 62 are both telescopic rods, and a locking component such as an electromagnet that can control the locking or unlocking of the telescopic rod is provided between the relatively telescopic rod segments. Then, when using the second driving component 62, the output ends of the first driving component 61 and the second driving component 62 can be unlocked by using the locking component. During this process, the output ends of the first driving component 61 and the second driving component 62 are shortened or extended.

[0085] Based on the above embodiments, the system further includes a first displacement sensor, a second displacement sensor, and a controller. The first displacement sensor is used to detect the displacement of the first chuck 11, and the second displacement sensor is used to detect the displacement of the second chuck 12. The controller is signal-connected to the first displacement sensor and the second displacement sensor to receive the displacement data of the first chuck 11 and the displacement data of the second chuck 12. The controller is also signal-connected to the first drive component 61 and / or the second drive component 62 and / or the third drive component 5, and is used to control the start and stop of the first drive component 61 and / or the second drive component 62 and / or the third drive component 5.

[0086] Specifically, in some embodiments, the controller can acquire the target displacement of the first clamp 11 and the second clamp 12 to be moved. This can be input via an input device such as a touch screen or keyboard, or via a signal connection to a control terminal, where the target displacement input by the control terminal is then transmitted to the controller. Before and during the movement of the first clamp 11 and / or the second clamp 12, the controller compares the received displacement data of the first clamp 11 and / or the second clamp 12 with the target displacement in real time. If the displacement data of the first clamp 11 and the second clamp 12 are not equal to their respective target displacements, the controller controls the first drive component 61 and / or the second drive component 62 and / or the third drive component 5 to operate until the displacement data of the first clamp 11 and the second clamp 12 are equal to their respective target displacements.

[0087] In other embodiments, the controller can output displacement data of the first chuck 11 and the second chuck 12, and has a first button for controlling the start and stop of the first drive component 61 and / or a second button for controlling the start and stop of the second drive component 62 and / or a third button for controlling the start and stop of the third drive component 5. In use, the displacement data of the first chuck 11 and the second chuck 12 are observed manually and compared with their respective target data. When the first drive component 61 needs to be started or stopped, the first button is pressed. Similarly, when the second drive component 62 needs to be started or stopped, the second button is pressed. When the third drive component 5 needs to be started or stopped, the third button is pressed.

[0088] Of course, the type of controller is not limited to the type in the example embodiments above, as long as it meets the control requirements.

[0089] It should be noted that the installation method of the first displacement sensor and the second displacement sensor is not limited, as long as the detection requirements are met. For example, the first displacement sensor and the second displacement sensor are respectively set in the first drive assembly 61 and the second drive assembly 62. Alternatively, the clamping device is also equipped with a worktable, and the first drive assembly 61, the second drive assembly 62, the first displacement sensor, and the second displacement sensor are all set on the worktable.
