Technical Field

[0001] The present invention relates to the technical field of the circular splicing of stator windings, and more specifically, to a servo motor stator circular splicing tooling. Background Art

[0002] In the prior art, a common servo motor stator is composed of 12 windings. During the motor production process, it is necessary to perform a circular splicing operation on the 12 windings, and then perform an assembly or welding operation on the spliced windings. Usually, a tooling with a fixed size is used to splice the 12 windings. However, it is relatively difficult to use this tooling for the circular splicing operation. Especially when splicing the last winding, it is very difficult to assemble it in place, resulting in a low efficiency of winding circular splicing.

[0003] In summary, how to provide a device that can effectively improve the efficiency of winding circular splicing is an urgent problem to be solved by those skilled in the art at present. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a servo motor stator circular splicing tooling, which can effectively improve the efficiency of circular splicing of stator windings, avoid the phenomenon that it is difficult to assemble the windings in place, and the structure of this device is simple and easy to use, and can be popularized and used.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] A servo motor stator circular splicing tooling includes: a movable positioning device for placing stator windings and a rotatable driving device for driving the movement of the positioning device. The positioning device includes at least two correspondingly arranged positioning members that can be spliced to form a complete ring. Each positioning member is provided with an arc-shaped groove for fixing the stator winding. The driving device is connected to the positioning member to drive each positioning member to move synchronously outward or inward.

[0007] Preferably, the driving device includes a turntable provided with a spiral groove and a guiding device for cooperating with the turntable to drive the positioning members to move synchronously. The guiding device is arranged at the bottom of the turntable and a rotating shaft penetrates through the centers of both of them;

[0008] The guiding device includes: a guiding pin that can penetrate through the spiral groove and is used to connect with the positioning member, a slider connected to the bottom of the guiding pin, and a track for moving the slider in a straight line direction. The slider and the track are both arranged corresponding to the spiral groove, so that when the turntable rotates, each guiding pin moves the same distance outward or inward.

[0009] Preferably, the positioning member includes an inner positioning block and an outer positioning block for connecting with the inner positioning block. The arc-shaped groove is clamped between the inner positioning block and the outer positioning block, and the guiding pin is connected to the bottom of the outer positioning block.

[0010] Preferably, the guiding device includes a guiding block for supporting and fixing the positioning member. One end of the guiding block is connected to the bottom of the outer positioning block, and the other end can be inserted into the track.

[0011] Preferably, the guiding block is of a C-shaped groove structure, and the turntable is arranged in the groove of the C-shaped groove structure.

[0012] Preferably, the driving device includes a base for supporting the turntable and the guiding device. The rotating shaft sequentially penetrates through the turntable, the guiding device and the base from top to bottom.

[0013] Preferably, vertical ribs for increasing the friction force are arranged on the outer peripheral part of the turntable.

[0014] When using the servo motor stator circular splicing tooling provided by the present invention, first, the driving device can be controlled to rotate, so that the driving device can drive each positioning member to move outward synchronously, thereby increasing the interval between the positioning members, so as to facilitate the operator to correspondingly place each stator winding into the arc-shaped groove of each positioning member; after the placement operation of the stator winding is completed, the driving device is rotated in the reverse direction, so that the driving device can drive each positioning member to move inward synchronously, so that the positioning members approach each other until the positioning members abut against each other and form a complete ring. At the same time, the stator windings in the arc-shaped groove can be spliced into a complete circle, that is, the circular splicing operation of the stator winding is realized.

[0015] In summary, the servo motor stator circular splicing tooling provided by the present invention can effectively improve the circular splicing efficiency of the stator winding, avoid the phenomenon that it is difficult to place the winding in place, and the device has a simple structure and is convenient to use, and can be popularized and used.

Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0024] The core of the present invention is to provide a servo motor stator circular splicing tooling, which effectively improves the circular splicing efficiency of the stator winding, avoids the phenomenon that the winding assembly is difficult to reach the position, and the device has a simple structure and is convenient to use, and can be popularized and used.

[0025] Please refer to Figures 1 to 4 , in which, 1 is the structural schematic diagram of the servo motor stator circular splicing tooling provided by the present invention; Figure 2 The sectional view when the servo motor stator circular splicing tooling performs the circular splicing operation on the stator winding; Figure 3 The structural schematic diagram of the guiding device; Figure 4 The structural schematic diagram of the turntable.

[0026] This specific embodiment provides a servo motor stator circular splicing tooling, including: a positioning device that is movable and used for placing the stator winding 2, and a driving device that is rotatable and used for driving the positioning device to move. The positioning device includes at least two correspondingly arranged positioning members that can be spliced to form a complete ring, and each positioning member is provided with an arc groove 1 for fixing the stator winding 2. The driving device is connected to the positioning member to drive each positioning member to move synchronously outward or inward.

[0027] It should be noted that the shape, size, number, etc. of the positioning members can be determined according to the actual situation and actual requirements. Since each positioning member can move outward or inward synchronously, when installing the stator winding 2, the installation space of the stator winding 2 can be enlarged by moving the positioning members outward synchronously, avoiding the phenomenon that the stator winding 2 is difficult to be assembled in place due to too small assembly space, so that the circular splicing operation of the stator winding 2 is very convenient and fast.

[0028] In the actual application process, the shape, structure, size, position, etc. of the positioning device and the driving device can be determined according to the actual situation and actual requirements.

[0029] It should also be noted that when using the servo motor stator circular splicing tooling provided by the present invention, first, the driving device can be controlled to rotate so that the driving device can drive each positioning member to move outward synchronously, thereby increasing the interval between the positioning members, so that the operator can correspondingly place each stator winding 2 into the arc-shaped grooves 1 of each positioning member; after the placement operation of the stator winding 2 is completed, the driving device is rotated in the reverse direction so that the driving device can synchronously drive each positioning member to move inward synchronously, so that the positioning members approach each other until the positioning members abut against each other and form a complete ring. At the same time, the stator windings 2 in the arc-shaped grooves 1 can be spliced into a complete circle, that is, the circular splicing operation of the stator winding 2 is realized.

[0030] In summary, the servo motor stator circular splicing tooling provided by the present invention can effectively improve the circular splicing efficiency of the stator winding 2, avoid the phenomenon that the winding assembly is difficult to be in place, and the device has a simple structure and is convenient to use, and can be popularized and used.

[0031] On the basis of the above embodiments, preferably, the driving device includes a turntable 3 provided with a spiral groove 31 and a guiding device 4 for cooperating with the turntable 3 to drive the positioning members to move synchronously. The guiding device 4 is arranged against the bottom of the turntable 3, and a rotating shaft 5 penetrates through the centers of both of them; the guiding device 4 includes: a guiding pin 41 that can penetrate through the spiral groove 31 and is used for connecting with the positioning member, a slider 42 for connecting with the bottom of the guiding pin 41, and a track 43 for moving the slider 42 in a straight line direction. The slider 42 and the track 43 are both arranged corresponding to the spiral groove 31, so that when the turntable 3 rotates, each guiding pin 41 moves outward or inward by the same distance.

[0032] In this embodiment, when the operator turns the turntable 3, the turntable 3 can rotate circumferentially. At the same time, the spiral notch inside the turntable 3 can drive the guide pin 41 to move. Since the bottom of the guide pin 41 is connected to the slider 42 and the slider 42 is arranged in the track 43, finally, the guide pin 41 will move linearly back and forth in a certain direction during the rotation. That is, when the turntable 3 rotates clockwise or counterclockwise, it will synchronously drive each guide pin 41 to move outward or inward by the same distance to realize the opening or contraction of each positioning member.

[0033] It should be noted that when the stator winding 2 needs to be assembled into a circle, the turntable 3 can be rotated to open the positioning members, thereby expanding the interval between the positioning members, which is more convenient for placing the stator winding 2 into the arc-shaped grooves 1 of the positioning members correspondingly. After the stator windings 2 are all placed, the turntable 3 is rotated in the reverse direction to make the positioning members contract, so as to realize the operation of assembling the stator winding 2 into a circle. This device can effectively improve the efficiency of assembling the stator winding 2 into a circle, and the operation of this device is simple and fast, and can be popularized and used.

[0034] In addition, it should be noted that the number of the guide pins 41, the sliders 42 and the tracks 43 provided by the guiding device 4 needs to be matched with the number of the positioning members. For example, when the number of the positioning members is 4, the number of the guide pins 41, the sliders 42 and the tracks 43 can all be set to 4, and the tracks 43 are perpendicular to each other and form a structure similar to a cross. However, the distances between the tracks 43 and the rotating shaft 5 are not the same, and the initial positions of the sliders 42 in the tracks 43 are not the same either. The specific positions of the tracks 43 and the sliders 42 need to be matched with the spiral notch 31 to ensure that when the turntable 3 rotates, each guide pin 41 moves outward or inward by the same distance.

[0035] In the actual application process, the shapes, structures, dimensions, positions, numbers, etc. of the spiral notch 31, the turntable 3, the guide pin 41, the slider 42, the track 43 and the rotating shaft 5 can be determined according to the actual situation and actual requirements.

[0036] Preferably, the positioning member includes an inner positioning block 6 and an outer positioning block 7 for connecting with the inner positioning block 6. An arc-shaped groove 1 is clamped between the inner positioning block 6 and the outer positioning block 7, and the guide pin 41 is connected to the bottom of the outer positioning block 7.

[0037] It should be noted that the inner positioning block 6 and the outer positioning block 7 are fixedly connected to ensure that the sizes of the arc grooves 1 between the two are consistent, so that the placement space of the stator winding 2 remains unchanged. However, since the guide pin 41 is connected to the bottom of the outer positioning block 7, when the guide pin 41 moves linearly in a certain direction as the turntable 3 rotates, it will be able to drive the outer positioning block 7 and the inner positioning block 6 to move synchronously, thereby effectively realizing the mutual separation and approach of the arc grooves 1. After the arc grooves 1 are separated from each other, the space for placing the stator winding 2 in the positioning member can be effectively increased, so as to facilitate the accurate and unobstructed placement of the stator winding 2 into each positioning member, and finally the circular assembly efficiency of the stator winding 2 can be effectively improved.

[0038] In the actual application process, the shapes, structures, sizes, positions, and numbers of the inner positioning block 6, the outer positioning block 7, and the arc groove 1 can be determined according to the actual situation and actual requirements.

[0039] On the basis of the above embodiments, preferably, the guiding device 4 includes a guiding block 44 for supporting and fixing the positioning member. One end of the guiding block 44 is connected to the bottom of the outer positioning block 7, and the other end can be inserted into the track 43.

[0040] It should be noted that by setting the guiding block 44, the extrusion force exerted by the positioning member on the guide pin 41 can be effectively reduced to avoid damage to the guide pin 41 due to excessive load. The guiding block 44 can effectively fix and support the positioning member. When the guide pin 41 moves linearly as the turntable 3 rotates, it will synchronously drive the positioning member and the guiding block 44 to move linearly, that is, the guiding block 44 can move synchronously along the track 43, and the guiding block 44 can effectively ensure the moving stability of the positioning member.

[0041] Preferably, the number of guiding blocks 44 can be the same as the number of positioning members, and the guiding blocks 44 are made of materials with better bearing capacity, so that the guiding blocks 44 can effectively fix and support the positioning members and ensure the balance and stability during the movement of the positioning members.

[0042] In the actual application process, the shapes, structures, numbers, positions, sizes, materials, etc. of the guiding blocks 44 can be determined according to the actual situation and actual requirements.

[0043] Preferably, the guiding block 44 has a C-shaped groove structure, and the turntable 3 is arranged in the groove of the C-shaped groove structure, so that the overall structure of the device is more compact, which is beneficial to reducing the space limitation of the device.

[0044] Preferably, the driving device includes a base 8 for supporting the turntable 3 and the guiding device 4, and the rotating shaft 5 sequentially passes through the turntable 3, the guiding device 4, and the base 8 from top to bottom.

[0045] It should be noted that a base 8 can be arranged under the guide device 4 so that the rotating shaft 5 passes through the turntable 3, the guide device 4 and the base 8 from top to bottom. Therefore, when the operator rotates the turntable 3, the guide device 4 and the turntable 3 will not deviate from the center, and the base 8 at the bottom can effectively support the turntable 3 and the guide device 4 to ensure the stability of the turntable 3 and the guide device 4.

[0046] In actual use, the shape, structure, size, material, etc. of the base 8 can be determined according to actual conditions and actual needs.

[0047] Preferably, the outer periphery of the turntable 3 is provided with vertical ribs 32 for increasing friction, so as to avoid idling due to the turntable 3 being too smooth when rotating. By evenly arranging a number of vertical ribs 32 on the outer periphery of the turntable 3, it will be easier for the operator to turn the turntable 3 better and with less effort. In actual use, the shape, structure, size, number, etc. of the vertical ribs 32 can be determined according to actual conditions and actual needs.

[0048] In order to better illustrate the use of the servo motor stator circle assembly tooling provided by the present invention, an example is given below.

[0049] When the stator winding 2 needs to be circled, first, the turntable 3 can be rotated to open the positioning parts, thereby expanding the intervals between the positioning parts, which makes it easier to place the stator winding 2 into the arc grooves 1 of the positioning parts. That is, the turntable 3 is rotated in a certain direction. At the same time, the spiral notch 31 inside the turntable 3 can drive the guide pin 41 to move linearly outward, and the guide pin 41 can drive the inner positioning block 6 and the outer positioning block 7 to open. Then, the stator winding 2 is placed into the positioning parts accordingly. After the stator winding 2 is placed, the turntable 3 is rotated in the opposite direction, so that the spiral notch 31 inside the turntable 3 drives the guide pin 41 to move linearly inward, and the guide pin 41 will drive the inner positioning block 6 and the outer positioning block 7 to contract, so as to realize the circled operation of the stator winding 2. This device can effectively improve the circled efficiency of the stator winding 2, and this device is simple and quick to operate, and can be promoted for use.

[0050] In addition, it should be noted that the directions or positional relationships indicated by "upper", "lower", "inner", "outer", etc. in this application are based on the directions or positional relationships shown in the drawings, and are only for the purpose of simplifying the description and facilitating understanding, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention.
