Description

Technical Field

[0001] This utility model relates to the technical field of insulating paper inserting machines, and in particular to a quick-change mold assembly and an insulating paper inserting machine. Background Technology

[0002] Most insulating paper inserters have a forming drive mechanism on one side of the forming mold to drive the upper cutter and forming blade in the forming mold away from or near the lower cutter and forming mold base fixed on the paper inserter, so as to achieve the cutting and forming of insulating paper.

[0003] For example, the utility model patent with patent number "CN215772876U" and title "Stator Insulation Paper Insertion Machine" discloses a stator insulation paper insertion machine, which includes a mold mechanism, a forming mechanism, and a position adjustment mechanism. The mold mechanism includes multiple molds, each with a forming groove, and can move to switch the target mold to the working position. The forming mechanism and the mold mechanism are arranged opposite to each other, and the forming mechanism can move closer to or further away from the mold mechanism. The forming mechanism includes an ejector and a moving cutter, with the ejector facing the opening of the forming groove of the target mold. The moving cutter is spaced apart on one side of the ejector along the same direction as the groove width of the target mold. The position adjustment mechanism is connected to the moving cutter and is used to drive the moving cutter closer to or further away from the ejector. The position of the moving cutter can be adjusted using the position adjustment mechanism, so that it can cooperate with the target mold to cut the insulation paper of the required width.

[0004] Because the moving cutter and ejector are connected to the molding drive mechanism, when the moving cutter and / or ejector need to be replaced, the moving cutter, ejector and molding drive structure need to be completely removed. When installing the replaced moving cutter and ejector, the positions of the moving cutter and ejector and the molding drive mechanism relative to the mold mechanism need to be readjusted to ensure the accuracy of distance control. This makes the replacement operation cumbersome and affects production efficiency. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a quick-change mold assembly for an insulating paper inserting machine and an insulating paper inserting machine, comprising: a mold assembly, including a movable blade holder and a fixed mold holder arranged opposite to each other, the movable blade holder being used to install an upper cutting blade and a forming blade, the fixed mold holder being used to install a lower cutting blade and a forming mold holder, the upper cutting blade and the lower cutting blade being used to cooperate in cutting the insulating paper, the forming blade and the forming mold holder being used to cooperate in forming the insulating paper; a displacement mechanism, including a distance adjusting member, a connecting block and a drive rod connected in sequence, the drive end of the distance adjusting member being connected to the movable blade holder, the connecting end of the distance adjusting member being slidably connected to the connecting block and fixed by fasteners, and the connecting block being shaft-connected to the drive rod.

[0007] According to one embodiment of the present invention, the distance adjusting component includes a connecting pin, a rod end joint bearing, an adjusting rod, and a movable female head connected in sequence. The connecting pin is installed on the movable tool holder, the rod end joint bearing is sleeved on the connecting pin, the adjusting rod is used to adjust the distance between the rod end joint bearing and the movable female head, and the movable female head is slidably connected to the connecting block and fixed by fasteners.

[0008] According to one embodiment of the present invention, it further includes a guide rod and a guide rod fixing seat. The fixed end of the guide rod is installed on the fixed mold base, and the movable end of the guide rod passes through the movable tool holder and is installed in the guide rod mounting hole of the guide rod fixing seat. The guide rod mounting hole includes at least two arc-shaped curved surfaces with different diameters. When the guide rod is installed in the guide rod mounting hole, the arc-shaped curved surface with the smallest diameter is tightly fitted with the arc surface of the guide rod.

[0009] According to one embodiment of the present invention, the movable end of the guide rod is provided with a tightening plane, and the guide rod fixing seat is provided with a tightening hole communicating with the guide rod mounting hole on one side of the guide rod mounting hole, so that the first tightening member 5 passes through the tightening hole and is tightly fitted with the tightening plane.

[0010] According to one embodiment of the present invention, the fixed mold base is provided with an elongated groove, the forming mold base is slidably connected to the elongated groove, and the lower cutter is installed on the forming mold base.

[0011] According to one embodiment of the present invention, a fixing strip is also installed on the long groove, and a fixing groove adapted to the fixing strip is opened on the forming mold base. The second clamping member abuts against the fixing groove through the fixed mold base and the fixing strip in sequence, thereby fixing the forming mold base, the fixing strip and the fixed mold base together.

[0012] According to one embodiment of the present invention, the forming mold base is provided with a forming groove opposite to the forming blade, and the forming blade extends into the forming groove to form insulating paper located between the two.

[0013] In addition, to achieve the above objectives, this utility model also proposes an insulating paper inserter.

[0014] An insulating paper inserter includes a quick-change mold assembly as described above.

[0015] According to one embodiment of the present invention, it further includes a stator drive mechanism and a paper pusher mechanism.

The paper feed plate is used to install the paper feed blocks. The two paper feed blocks and the paper feed roller form a paper feeding channel located on one side of the paper feed roller.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention achieves this by slidably connecting the connecting end of the distance adjustment component of the displacement mechanism to the connecting block and fixing it with fasteners. When it is necessary to replace the upper cutter and / or forming cutter, the fasteners can be loosened, allowing the connecting end of the distance adjustment component to slide out of the connecting block, and the distance adjustment component and the movable cutter holder equipped with the upper cutter and forming cutter can be removed together. When installing the movable cutter holder, simply slide the connecting end of the distance adjustment component into the connecting block and lock the fasteners to replace the upper cutter and / or forming cutter. Without changing the connecting block and drive rod, since the connection relationship between the movable cutter holder and the distance adjustment component does not change, there is no need to adjust the position of the movable cutter holder and the distance adjustment component relative to the fixed mold base after replacement, simplifying disassembly and installation operations and thus effectively improving production efficiency.

[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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0032] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0033] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0034] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0035] like Figures 1 to 3 As shown, the quick-change mold assembly of the insulating paper inserting machine of this utility model includes: a mold assembly 1 and a displacement mechanism 2. The mold assembly 1 includes a movable cutter holder 11 and a fixed mold holder 12 arranged opposite to each other. The movable cutter holder 11 is used to install an upper cutter 13 and a forming cutter 14. The fixed mold holder 12 is used to install a lower cutter 15 and a forming mold holder 16. The upper cutter 13 and the lower cutter 15 are used to cooperate to cut the insulating paper. The forming cutter 14 and the forming mold holder 16 are used to cooperate to form the insulating paper. The displacement mechanism 2 includes a distance adjusting member 21, a connecting block 22 and a drive rod 23 connected in sequence. The drive end of the distance adjusting member 21 is connected to the movable cutter holder 11. The connecting end of the distance adjusting member 21 is slidably connected to the connecting block 22 and fixed by a fastener 24. The connecting block 22 is axially connected to the drive rod 23 so that the drive rod 23 provides driving force to the movable cutter holder 11 through the connecting block 22 and the distance adjusting member 21, causing the movable cutter holder 11 to move away from or closer to the fixed mold holder 12.

[0036] Understandably, since the connecting end of the distance adjustment component 21 is slidably connected to the connecting block 22 and fixed by the fastener 24, when it is necessary to replace the upper cutter 13 and / or the forming cutter 14, the fastener 24 can be loosened to allow the connecting end of the distance adjustment component 21 to slide out from the connecting block 22, and the distance adjustment component 21 and the movable cutter holder 11 on which the upper cutter 13 and the forming cutter 14 are installed can be removed together; then the replaced upper cutter 13 and / or the forming cutter 14 can be reinstalled on the movable cutter holder 11, and the connecting end of the distance adjustment component 21 can be slid into the connecting block 22 and the fastener 24 can be locked, thus realizing the replacement of the upper cutter 13 and / or the forming cutter 14. Without changing the connecting block 22 and the drive rod 23, since the connection relationship between the movable cutter holder 11 and the distance adjustment component 21 has not changed, there is no need to adjust the position of the movable cutter holder 11 and the distance adjustment component 21 relative to the fixed mold base 12 after replacement. The replacement operation is relatively simple and can effectively improve production efficiency.

[0037] In one embodiment of this utility model, the forming mold base 16 may be provided with a forming groove 161 opposite to the forming blade 14, and the forming blade 14 extends into the forming groove 161 to realize the forming of insulating paper located between the two. In other embodiments of this utility model, a forming mold matching the forming blade 14 may also be installed on the forming mold base 16 to cooperate with the forming blade 14 to realize the forming of insulating paper, etc., and this embodiment does not limit it.

[0038] In one embodiment of this utility model, the distance adjusting member 21 may include a connecting pin 211, a rod end spherical bearing 212, an adjusting rod 213, and a movable female head 214 connected in sequence. The connecting pin 211 is mounted on the movable tool holder 11, the rod end spherical bearing 212 is sleeved on the connecting pin 211, the adjusting rod 213 is used to adjust the distance between the rod end spherical bearing 212 and the movable female head 214, and the movable female head 214 is slidably connected to the connecting block 22 and fixed by a fastener 24. The fastener 24 may be a set screw or other locking method, and this embodiment is not limited to this.

[0039] During the initial installation of the movable tool holder 11, the connecting pin 211 and the rod end spherical bearing 212 can be continuously installed on the movable tool holder 11. The movable tool holder 11 can be placed in an area roughly the same as the preset position, and the position of the drive rod 23 can be fixed. Then, the distance adjustment component 21 connects the movable tool holder 11 and the connecting block 22. By adjusting the adjusting rod 213 in the distance adjustment component 21, the distance between the rod end spherical bearing 212 and the movable female head 214 is adjusted, thereby adjusting the position of the movable tool holder 11 and initializing the relative distance between the movable tool holder 11 and the fixed mold base 12. Since the distance initialization is completed during the initial installation of the movable tool holder 11, the adjusting rod 213 does not need to be adjusted during subsequent disassembly and installation of the movable tool holder 11, ensuring the accuracy of distance control between the movable tool holder 11 and the fixed mold base 12.

[0040] In one embodiment of this utility model, a guide rod 3 and a guide rod fixing seat 4 are also included. The fixed end 31 of the guide rod 3 is mounted on the fixed mold base 12, and the movable end 32 of the guide rod 3 passes through the movable tool holder 11 and is installed in the guide rod mounting hole 41 of the guide rod fixing seat 4, so that when the movable tool holder 11 is driven by the displacement mechanism 2, it moves along the length direction of the guide rod 3. The guide rod mounting hole 41 includes at least two arc-shaped curved surfaces with different diameters. When the guide rod 3 is installed in the guide rod mounting hole 41, the arc-shaped curved surface with the smallest diameter is tightly fitted with the arc surface 33 of the guide rod 3. Figure 4 As shown. Specifically, pressure can be applied to the guide rod 3 through mortise and tenon structures, elastic elements, clamping elements, etc., so that the arc surface 33 of the guide rod 3 fits tightly with the arc surface with the smallest diameter, thereby fixing the movable end 32 of the guide rod 3. This embodiment does not impose any limitations.

[0041] It is understandable that, since the guide rod mounting hole 41 includes at least two arc-shaped surfaces with different diameters, when only the movable end 32 of the guide rod 3 exists in the guide rod mounting hole 41, the movable end 32 of the guide rod 3 has a certain amount of room to move within the guide rod mounting hole 41, which facilitates the quick removal of the guide rod fixing seat 4 from the guide rod 3, thereby allowing the movable tool holder 11 to be removed from the guide rod 3; moreover, the arc-shaped surface with the smallest diameter can fit tightly with the arc surface 33 of the guide rod 3, which can better ensure the stability of the position of the guide rod 3 when the guide rod 3 is installed in the guide rod mounting hole 41.

[0042] Preferably, such as Figure 5 As shown, the movable end 32 of the guide rod 3 is provided with a clamping surface 34. The guide rod fixing seat 4 has a clamping hole 42 on one side of the guide rod mounting hole 41, which communicates with the guide rod mounting hole 41, so that the first clamping component, such as a set bolt, passes through the clamping hole 42 and is tightly fitted with the clamping surface 34. When removing the guide rod fixing seat 4, the first clamping component can be directly loosened and the guide rod fixing seat 4 can be removed directly. The first clamping component can be partially left in the clamping hole 42, which is convenient for the next installation and has high maintenance efficiency.

[0043] In one embodiment of this utility model, such as Figure 2 As shown, the fixed mold base 12 is provided with a long groove 121, the forming mold base 16 is slidably connected to the long groove 121, and a lower cutter 15 is installed on the forming mold base 16, so as to facilitate the simultaneous removal of the forming mold base 16 and the lower cutter 15 for maintenance and replacement of the forming mold base 16 and / or the lower cutter 15.

[0044] Preferably, a fixing strip 122 is also installed on the elongated groove 121, and a fixing groove 162 adapted to the fixing strip 122 is formed on the forming mold base 16. A second clamping member (not shown in the figure), such as a set screw, abuts against the fixing groove 162 through the fixed mold base 12 and the fixing strip 122 in sequence, thereby fixing the forming mold base 16, the fixing strip 122 and the fixed mold base 12 together. When removing the forming mold base 16, the second clamping member can be directly loosened and removed. The second clamping member can be partially left in the fixing strip 122, which is convenient for the next installation and has high maintenance efficiency.

[0045] In addition, to achieve the above objectives, this utility model also proposes an insulating paper inserter.

[0046] like Figure 7 As shown, the insulating paper inserting machine of this utility model embodiment includes the mold quick-change assembly as described above. The fixed mold base 12 of the mold quick-change assembly can be installed on the operating table 5. The operating table 5 also has a movable space suitable for the movement of the drive rod 23 of the mold quick-change assembly, so that the movable cutter holder 11 can cooperate with the fixed mold base 12 on the operating table 5 under the drive of the displacement mechanism 2 to cut and form the insulating paper.

[0047] The insulating paper inserter of this utility model embodiment, since it includes the mold quick-change assembly as described above, also has the aforementioned beneficial effects.

[0048] In one embodiment of this utility model, the insulating paper insertion machine further includes a stator drive mechanism 6 and a paper pushing mechanism 7. The stator drive mechanism 6 includes a turntable 61 and a gear set 62 for driving the turntable 61 to rotate. The turntable 61 is provided with a stator mounting seat 63, which is used to fix the relative position of the stator and the turntable 61, so that the stator can rotate synchronously with the turntable 61. The turntable 61 is also provided with a channel communicating with the stator slot of the stator. The paper pushing mechanism 7 is used to push the formed insulating paper in the forming mold base 16 through the channel and insert it into the stator slot. Thus, after the insulating paper is formed into formed insulating paper in the forming mold base 16, the paper pushing mechanism 7 can push the formed insulating paper into the stator slot.

[0049] When it is necessary to replace parts on the movable tool holder 11 and / or the fixed mold holder 12, such as the upper cutter 13, the turntable 61 must be removed first, and then the replacement should be carried out based on the disassembly and replacement method described above, which will not be repeated here.

[0050] In one specific embodiment of this utility model, such as Figure 8 As shown, the paper pushing mechanism 7 may include a push rod 71. When the insulating paper is formed in the forming groove 161 on the forming mold base 16, the forming groove 161 is suitable for the push rod 71 to pass through. The push rod 71 sequentially passes through the forming groove 161 and the channel on the turntable 61 to insert the formed insulating paper into the stator groove, thereby realizing the paper insertion action.

[0051] In one embodiment of this utility model, the insulating paper inserter further includes a paper feeding mechanism 8, such as... Figure 9 As shown, the paper feeding structure 8 may include two paper feed blocks 81 with adjustable relative distance, a paper feed roller 82, and a paper feed plate 83. The paper feed roller 82 is used to transport the insulating paper between the two paper feed blocks 81 to the space between the movable blade holder 11 and the fixed mold holder 12 of the mold quick-change assembly. The paper feed plate 83 is used to mount the paper feed blocks 81 so that the two paper feed blocks 81 and the paper feed plate 83 form a paper feed channel located on one side of the paper feed roller 83. A width adjustment screw may be provided between the two paper feed blocks 81. The width between the two paper feed blocks 81 can be adjusted by adjusting the width adjustment screw. Alternatively, other mechanisms such as gears and racks can be used to adjust the position of the two paper feed blocks 81 relative to the paper feed plate 83 to achieve width adjustment, etc. This embodiment does not impose any limitations.

[0052] Understandably, since the distance between the two paper feed blocks 81 is adjustable, the distance between the two paper feed blocks 81 can be adjusted according to the width of the insulating paper during feeding to ensure that the paper feeding angle is relatively consistent and to avoid the insulating paper shifting during feeding, which would lead to the cutting or forming effect not meeting expectations and affecting the insulation effect.

[0053] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
