Description

Technical Field

[0001] This utility model belongs to the field of motor manufacturing technology, specifically relating to a split-type motor frame assembly mechanism. Background Technology

[0002] A modular motor is an electronic control component widely used in the air conditioning and refrigeration environments of various automobiles. It primarily controls the rotation of its internal rotor after external power is applied, thereby controlling the air conditioning cooling function. The stator of a modular motor is mainly composed of modular coils. These modules are assembled from an iron core and a frame. The frame completely encloses the iron wire to prevent it from damaging the copper wire during winding. Simultaneously, the frame provides slots for winding and arranging the copper wire according to these slots, ensuring the integrity of the winding and meeting the quality requirements of the modular motor stator.

[0003] However, the existing assembly of the frame and core uses traditional manual assembly. The frame and core fit together tightly, making manual assembly difficult. The core can easily scratch the frame and hands, and the operation is physically demanding. In addition, for mass production, manual operation cannot meet the high-volume requirements and increases labor costs and production cycle time.

[0004] Therefore, there is an urgent need for a split-type motor frame assembly mechanism that can reduce the labor intensity of operators and improve the assembly efficiency of the frame and core. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a split motor frame assembly mechanism, which solves the problems of high difficulty, low efficiency and difficulty in ensuring assembly quality in the assembly of the frame and iron core on the stator blocks of the existing segmented motor.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a split motor frame assembly mechanism, including an iron core and a frame, wherein the assembly mechanism includes a lower positioning fixture, an upper positioning fixture, and a pressure rod capable of reciprocating along a first direction;

[0007] The iron core can be placed upright on the lower positioning fixture along its assembly direction with the skeleton, and the skeleton can be slidably connected to the upper positioning fixture along its assembly direction with the iron core. The iron core placed on the lower positioning fixture can move with the lower positioning fixture to correspond to the skeleton on the lower positioning fixture, and the assembly direction between the iron core and the skeleton is consistent with the first direction.

[0008] Optionally, the frame is provided with a U-shaped slot that can engage with the iron core, and the outer periphery of the frame is provided with a wire groove for winding electromagnetic wire, the sidewall of the wire groove being perpendicular to the sidewall of the U-shaped slot.

[0009] The upper positioning fixture includes a first clamping arm and a second clamping arm that can be symmetrically and movably embedded in the wire groove, and an inner support rod that can move between the first clamping arm and the second clamping arm and be movably embedded in the U-shaped groove. The side wall of the wire groove can be clearance-fitted with the outer periphery of the first clamping arm and the second clamping arm, and the side wall of the U-shaped groove can be clearance-fitted with the outer periphery of the inner support rod. The planes on the skeleton placed on the upper positioning fixture, where the side walls of the wire groove and the U-shaped groove are located, are parallel to or coincide with the first direction.

[0010] Optionally, when the pressure rod presses down on the skeleton placed on the upper positioning fixture and moves to be inserted into the iron core on the lower positioning fixture, the inner support rod can be moved out of the U-shaped slot.

[0011] Optionally, it also includes a push rod that can move synchronously with the pressure rod along the first direction. The push rod has a curved profile on one side along the first direction. The inner support rod is slidably connected to the fixture base along a second direction perpendicular to the first direction. The first clamping arm and the second clamping arm can be detachably connected to the fixture base by fasteners such as bolts in the prior art. The inner support rod is rotatably connected to a limiting bearing that can roll along the curved profile. The fixture base is provided with a return spring that can elastically support the inner support rod.

[0012] Furthermore, as the push rod moves synchronously toward the lower positioning fixture along the first direction with the pressure rod, the inner support rod can compress the return spring, and one end of the inner support rod can move out of the U-shaped groove on the skeleton.

[0013] Optionally, the fixture base includes a base and a cover plate connected to the top of the base, and a limiting cavity is formed between the base and the cover plate for sliding connection of the inner support rod. The end of the return spring abuts against the inner support rod and the side wall of the limiting cavity respectively along the second direction. The push rod can be inserted into the limiting cavity through the through hole provided on the top of the cover plate, and push the inner support rod toward the limiting cavity through the limiting bearing.

[0014] When the return spring drives the inner support rod to move along the second direction until its end is inserted into the frame, the limiting wing provided on the inner support rod can abut against the side wall of the limiting cavity along the second direction.

[0015] Optionally, the lower positioning fixture includes a fixture platform and a fixture block slidably connected to the fixture platform along a second direction. The fixture block is provided with a contour groove for embedding the iron core along a first direction, and a positioning block that can be inserted and engaged with the iron core along the first direction is provided in the contour groove.

[0016] Optionally, the fixture platform and the fixture block are slidably connected by a linear guide rail, and the fixture block is equipped with a push-pull handle.

[0017] Optionally, the lower positioning fixture and the fixture base are fixedly connected to the base plate, the pressure rod and the push rod are fixedly connected to the pressure plate, the base plate is provided with a plurality of guide optical shafts that are parallel to each other and arranged along a first direction, the pressure plate is provided with a plurality of linear bearings that can be slidably connected to the guide optical shafts, and one end of each of the guide optical shafts away from the base plate and the pressure plate is fixedly connected to the top plate, the top plate is provided with a linear drive unit, and the output end of the linear drive unit is fixedly connected to the pressure plate, and the linear drive unit can drive the pressure plate to reciprocate along the first direction.

[0018] Optionally, the base plate is provided with a number of sensors that can be electrically connected to the linear drive unit.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0020] (1) The precise assembly of the iron core and the skeleton is achieved through the cooperation of the lower positioning fixture, the upper positioning fixture, and the pressure rod. The lower positioning fixture can hold the iron core upright and move it to the position corresponding to the skeleton. The upper positioning fixture makes the skeleton slide along the assembly direction. The pressure rod presses down on the skeleton along the first direction to ensure the consistency of the assembly direction, thereby improving the insertion accuracy and stability. This structure reduces manual intervention, reduces assembly errors, and improves production efficiency. It is suitable for automated production lines. Moreover, the positioning of the fixtures can adapt to iron cores and skeletons of different specifications, enhancing versatility and flexibility.

[0021] (2) The cam mechanism, consisting of the fixture base, return spring, inner support rod, limit bearing, push rod and its curved contour, enables the insertion and extraction action between the inner support rod and the U-shaped groove and the pressing action of the pressure rod to work together efficiently. This effectively improves the continuity of the actions of each component of the assembly mechanism and avoids interference between the actions of each component. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. Example 1

[0032] like Figures 1-6 As shown, a split-type motor frame assembly mechanism includes an iron core 1 and a frame 2. The assembly mechanism includes a lower positioning fixture 3, an upper positioning fixture 4, and a pressure rod 5 that can reciprocate along a first direction. The pressure rod 5 can cooperate with a linear drive device in the prior art. The linear drive device (such as a servo slide, linear motor, cylinder, hydraulic cylinder, electric push rod 6, etc.) can drive the pressure rod 5 to reciprocate along the first direction, and the output force of the linear drive device can enable the pressure rod 5 to have the required thrust. Specifically, the iron core 1 can be placed upright on the lower positioning fixture 3 along the assembly direction with the frame 2, and the frame 2 can be slidably connected to the upper positioning fixture 4 along the assembly direction with the iron core 1. In this technical solution, the iron core 1 and the frame 2 can be loaded by an operator or robot so that the iron core 1 is placed in a fixed position on the lower positioning fixture 3 and the frame 2 is slidably connected to a fixed position on the upper positioning fixture 4. It should be noted that the frame 2 placed on the upper positioning fixture 4 and the upper positioning fixture 4 are in a clearance fit, but the friction between the two is relatively small, and the frame 2 cannot slide off the upper positioning fixture 4 under its own gravity. Since the iron core 1 placed on the lower positioning fixture 3 can move with the lower positioning fixture 3 to correspond with the skeleton 2 on the lower positioning fixture 3, and the assembly direction between the iron core 1 and the skeleton 2 is consistent with the first direction, the pressure rod 5 can press down the skeleton 2 placed on the upper positioning fixture 4 to move it to engage with the iron core 1 on the lower positioning fixture 3. The end of the pressure rod 5 can make uniform and sufficient contact with the top side of the skeleton 2, and the pressure rod 5 can apply pressure evenly to the skeleton 2, so that the skeleton 2 can be precisely assembled with the iron core 1. The whole process does not require much manual intervention, which ensures the personal safety of the operator, reduces the labor intensity of the operator, and improves production efficiency.

[0033] Meanwhile, in this technical solution, since the lower positioning fixture 3 can move relative to the upper positioning fixture 4, before the loading operation of the iron core 1 is carried out, the lower positioning fixture 3 can be moved to outside the coverage area of ​​the upper positioning fixture 4, thereby avoiding interference between the loading operation of the upper positioning fixture 4 and the loading operation of the lower positioning fixture 3, and also facilitating the operation of the operator or robot to pick up materials.

[0034] Furthermore, such as Figure 5 , Figure 6 As shown, in this technical solution, the frame 2 is provided with a U-shaped slot 201 that can engage with the iron core 1, and the outer periphery of the frame 2 is provided with a wire groove 202 for winding electromagnetic wire. The sidewall of the wire groove 202 is perpendicular to the sidewall of the U-shaped slot 201. The upper positioning fixture 4 includes a first clamping arm 401 and a second clamping arm 402 that can be symmetrically and movably embedded in the wire groove 202, and an inner support rod 403 that can move between the first clamping arms 401 and movably embedded in the U-shaped slot 201. Specifically, as shown... Figure 6 As shown. It should be noted that the sidewall of the wire groove 202 can be fitted with the outer periphery of the first clamping arm 401 and the second clamping arm 402 with clearance, and the sidewall of the U-shaped groove 201 can be fitted with the outer periphery of the inner support rod 403 with clearance. The planes on the frame 2 placed on the upper positioning fixture 4, where the sidewalls of the upper wire groove 202 and the U-shaped groove 201 are located, are parallel to or coincide with the first direction. Therefore, by the cooperation of the first clamping arm 401, the second clamping arm 402 and the inner support rod 403, the five degrees of freedom of the frame 2 can be restricted, so that the frame 2 can only move up and down along the first direction, that is, the frame 2 can slide and connect to the upper positioning fixture 4 along its assembly direction with the iron core 1.

[0035] Furthermore, in this technical solution, when the pressure rod 5 presses down on the skeleton 2 placed on the upper positioning fixture 4 and moves it to the point where it is inserted into the iron core 1 on the lower positioning fixture 3, the inner support rod 403 can be moved out from the U-shaped slot 201. It should be noted that during this process, the inner support rod 403 can be moved out after the skeleton 2 is partially assembled with the iron core 1 at the open end of the U-shaped slot 201 and forms a closed loop structure. At this time, the assembly direction between the skeleton 2 and the iron core 1 is locked, and the pressure rod 5 only needs to continue pressing down on the skeleton 2 along the first direction to continue the assembly operation between the skeleton 2 and the iron core 1. The removal of the inner support rod 403 from the U-shaped slot 201 at this time avoids the inner support rod 403 affecting the complete insertion (assembly) of the skeleton 2 and the iron core 1.

[0036] Furthermore, in this embodiment, as Figure 3 , Figure 4As shown, it also includes a push rod 6 that can move synchronously with the pressure rod 5 along the first direction. A curved profile portion 601 is provided on one side of the push rod 6 along the first direction. The inner support rod 403 is slidably connected to the fixture base 7 along a second direction perpendicular to the first direction. A limiting bearing 8 that can roll along the curved profile portion 601 is rotatably connected to the inner support rod 403. A return spring 9 that can elastically support the inner support rod 403 is provided on the fixture base 7. Specifically, the fixture base 7, return spring 9, inner support rod 403, and limit bearing 8 can form a cam mechanism in the prior art with the push rod 6 and its curved profile 601. That is, when the push rod 6 moves synchronously with the pressure rod 5 towards the lower positioning fixture 3 in the first direction, the curved profile 601 on the push rod 6 can fit against the outer periphery of the limit bearing 8, and the limit bearing 8 can move relative to the fixture base 7 along the second direction along the curved profile 601. The inner support rod 403 can move synchronously with the limit bearing 8 along the second direction, so that the inner support rod 403 can compress the return spring 9. It should be noted that in this technical solution, the two ends of the return spring 9 are respectively embedded in the fixture base 7 and the inner support rod 403 to limit the axial direction of the return spring 9 and make its axial direction parallel to the second direction, so as to avoid the return spring 9 bending due to uneven force, thereby affecting the supporting effect on the inner support rod 403. Furthermore, the return spring 9 can store energy when compressed, thus providing a return thrust to the inner support rod 403 when needed. It should be noted that during this process, one end of the inner support rod 403 can be moved out of the U-shaped slot 201 on the frame 2. Therefore, in this technical solution, the insertion and removal action between the inner support rod 403 and the U-shaped slot 201 is coordinated with the downward pressing action of the pressure rod 5. The two cooperate to ensure that the inner support rod 403 can be moved out of the U-shaped slot 201 in a timely manner when the frame 2 and the iron core 1 are initially inserted, thereby improving the continuity of the actions of each component of the assembly mechanism and avoiding interference between the actions of different components.

[0037] Furthermore, such as Figure 5 , Figure 6 As shown, the fixture base 7 includes a base 701 and a cover plate 702 connected to the top of the base 701. A limiting cavity 703 for sliding connection of the inner support rod 403 is formed between the base 701 and the cover plate 702. The end of the return spring 9 abuts against the inner support rod 403 and the side wall of the limiting cavity 703 along the second direction. The push rod 6 can be inserted into the limiting cavity 703 through the through hole provided on the top of the cover plate 702, and pushes the inner support rod 403 toward the limiting cavity 703 through the limiting bearing 8. When the return spring 9 drives the inner support rod 403 to move along the second direction until its end is inserted into the frame 2, the limiting wing 4031 provided on the inner support rod 403 can abut against the side wall of the limiting cavity 703 along the second direction, thereby limiting the ultimate movement distance of the inner support rod 403.

[0038] Furthermore, in this technical solution, such as Figure 5 , Figure 6 As shown, the lower positioning fixture 3 includes a fixture platform 301 and a fixture block 302 slidably connected to the fixture platform 301 along a second direction. The fixture block 302 has a contoured groove 3021 along a first direction for embedding the iron core 1, and a positioning block 3022 is provided within the contoured groove 3021 that can be inserted and engaged with the iron core 1 along the first direction. The contoured groove 3021 and the positioning block 3022 on the fixture block 302 ensure the uniqueness of the position of the iron core 1 on the fixture block 302. Simultaneously, the fixture block 302, which can move relative to the fixture platform 301, increases the flexibility of loading and unloading the iron core 1, facilitating material handling operations for operators or robots.

[0039] It should be noted that in this technical solution, to ensure the assembly accuracy of the frame 2 and the iron core 1, the fixture platform 301 and the fixture block 302 are slidably connected by a linear guide rail 10. The linear guide rail 10 is existing technology and mainly consists of a slider and a guide rail, with the slider slidably connected to the guide rail. However, in this embodiment, the guide rail is fixedly connected to the fixture platform 301, and the slider is fixedly connected to the fixture block 302. The sliding connection between the slider and the guide rail improves the accuracy of the linear movement of the iron core 1 in the second direction. Simultaneously, in this embodiment, a push-pull handle 11 is connected to the fixture block 302, allowing the operator to drive the fixture block 302 to move in the second direction by operating the push-pull handle 11, thus facilitating manual material handling.

[0040] Furthermore, after the pressure rod 5 presses down on the skeleton 2 to complete the assembly operation with the iron core 1, it can be lifted off the pressure rod 5 and gradually raised in height. During this process, the compressed return spring 9 can gradually release the energy accumulated due to compression, driving the inner support rod 403 to move along the first direction until the end of the inner support rod 403 returns to the position where it can be inserted into the U-shaped slot 201 of the skeleton 2 that was originally slidably connected to the upper positioning fixture 4. At this time, since the skeleton 2 and the iron core 1 are still in the assembly position after the assembly is completed, and part of the skeleton 2 assembled on the iron core 1 is now higher than the position of the iron core 1, the inner support rod 403, which is reset by the return spring 9, can drive the assembled skeleton 2 and the iron core 1 away from the assembly position, thereby facilitating the operator to pick up materials and carry out the next loading operation of the iron core 1.

[0041] It should be noted that the first direction in this technical solution corresponds to the positive and negative directions of the Z-axis in a spatial rectangular system, and the second direction corresponds to the positive and negative directions of the X-axis or Y-axis in a spatial rectangular system. Example 2

[0042] like Figures 1-6As shown, based on Embodiment 1, the lower positioning fixture 3 and fixture base 7 are fixedly connected to the base plate 12, and the pressure rod 5 and push rod 6 are fixedly connected to the pressure plate 13. The base plate 12 is provided with several parallel guide optical shafts 14 arranged along a first direction. The pressure plate 13 is provided with several linear bearings 15 that can slide with the guide optical shafts 14. The ends of the guide optical shafts 14 facing away from the base plate 12 and pressure plate 13 are all fixedly connected to the top plate 16. The top plate 16 is provided with a linear drive unit 17, and the output end of the linear drive unit 17 is fixedly connected to the pressure plate 13. The linear drive unit 17 can drive the pressure plate 13 to reciprocate along the first direction. The linear drive unit 17 is a prior art device, such as a servo slide, linear motor, cylinder, hydraulic cylinder, or electric push rod.

[0043] Meanwhile, the base plate 12 is equipped with several sensors 18 that can be electrically connected to the linear drive unit 17. The sensors 18 are existing technologies, such as infrared sensors, position sensors, distance sensors, etc. The sensors 18 in this technical solution can be used to detect whether there is a skeleton 2 on the upper positioning fixture 4, whether there is an iron core 1 on the lower positioning fixture 3, and whether the iron core 1 on the lower positioning fixture 3 moves to the assembly position with the fixture block 302. Through the electrical control cooperation between the sensors 18 and the linear drive unit 17, the various components in the assembly mechanism can work together to improve production efficiency, monitor the operating status of the assembly mechanism, detect abnormalities in advance, and avoid sudden shutdowns.

[0044] Working principle: First, the iron core 1 and the frame 2 can be loaded by operators or robots, so that the iron core 1 is placed upright in a fixed position on the lower positioning fixture 3, and the frame 2 is slidably connected to a fixed position on the upper positioning fixture 4. Since the iron core 1 placed on the lower positioning fixture 3 can move with the lower positioning fixture 3 to correspond with the frame 2 on the lower positioning fixture 3, and the assembly direction between the iron core 1 and the frame 2 is consistent with the first direction, the linear drive unit 17 drives the pressure rod 5 to press down on the frame 2 placed on the upper positioning fixture 4, so that it can move to the position where it can be inserted and matched with the iron core 1 on the lower positioning fixture 3. The end of the pressure rod 5 can make uniform and sufficient contact with the top side of the frame 2, and the pressure rod 5 can apply pressure evenly to the frame 2, so that the frame 2 can be precisely assembled with the iron core 1. The whole process does not require much manual intervention, which ensures the personal safety of the operator, reduces the labor intensity of the operator, and improves production efficiency.

[0045] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
