Description

Technical Field

[0001] This utility model relates to the field of physics, and in particular to measurement technology, specifically a tooling for detecting the dimensions of the stator windings of a drive motor. Background Technology

[0002] In the production process of drive motors, the accuracy of the inner and outer diameter dimensions of the stator windings directly affects the electromagnetic performance and assembly reliability of the motor.

[0003] Existing methods for detecting the inner and outer diameters of drive motor stator windings mainly fall into two categories: The first method involves manually clamping the winding with vernier calipers / digital calipers to detect its inner and outer diameters. However, this method has significant drawbacks. Since center alignment relies on manual visual alignment, the measurement accuracy is heavily influenced by the operator's experience, making it difficult to accurately locate the center. Furthermore, caliper tilting can easily lead to non-orthogonal measurements, increasing measurement errors and affecting the final inspection results. The second method uses specialized testing equipment, such as coordinate measuring machines (CMMs). While this method can achieve μm-level measurement accuracy, its equipment is expensive and complex to operate. It requires uniformly collecting ≥12 points around the winding circumference, with each point measurement taking approximately 30 seconds, and a single-piece full inspection taking over 6 minutes. This results in low inspection efficiency, making it difficult to meet the requirements of batch full inspection. Utility Model Content

The base plate is fixedly installed on the upper surface of the base platform, and a base plate positioning hole is provided on the upper surface of the base platform. The lower surface of the base plate is inserted into the base plate positioning hole through a base plate positioning pin. The base plate and the lifting top plate are connected by a scissor-type lifting mechanism. The caliper mounting plate is fixedly installed on the upper surface of the lifting top plate.

[0014] Preferably, the scissor lift mechanism includes two sets of cross support assemblies and a lifting drive assembly. The two sets of cross support assemblies are respectively arranged on both sides above the base plate. Each set of cross support assemblies includes a first support plate, a second support plate, a third support plate, and a fourth support plate. The first support plate and the second support plate are cross-hinged, and the third support plate and the fourth support plate are cross-hinged. The upper surface of the base plate is provided with first hinge plates on both the left and right sides, and the lower surface of the lifting top plate is provided with second hinge plates on both the left and right sides.

[0015] The lifting drive assembly includes a first connecting plate, a second connecting plate, and a lead screw. The two ends of the first connecting plate are fixedly connected to two first cylinders, and the two ends of the second connecting plate are fixedly connected to two second cylinders. The first connecting plate and the second connecting plate are respectively provided with a first threaded hole and a second threaded hole in the middle.

The rear end of the lead screw passes through the first threaded hole and the second threaded hole in sequence and is threadedly connected to the first connecting plate and the second connecting plate. A handwheel is fixedly installed at the front end of the lead screw.

[0016] Preferably, the caliper assembly includes a caliper fixing shaft, a digital caliper, a linear slide rail, and a measuring plate. The caliper fixing shaft and the linear slide rail are both horizontally fixedly installed on the side of the caliper mounting plate.

[0018] This utility model provides a fixture for detecting the dimensions of a drive motor stator winding, which has the following advantages: By installing the zero-alignment component onto the positioning post, the zero-position surface of the zero-alignment component is completely in contact with the outer measuring contact surface of the measuring contact at the left end of the measuring plate. This indicates that the outer measuring contact surface coincides with the vertical section in the front-back direction where the stator center is located, and the vertical center plane in the left-right direction of the measuring plate coincides with the vertical section in the left-right direction where the stator center is located. This achieves zero-position calibration of the digital caliper. When detecting the outer diameter of the stator winding, simply align the outer measuring contact surface at the left end of the measuring plate with the outer surface of the stator winding, and then contact the digital display block of the digital caliper with the reading block at the right end of the measuring plate. The value displayed by the digital caliper is then the precise dimension of the stator winding's outer diameter. When inspecting the inner diameter of the stator winding, an upgrade platform can be used to move the caliper assembly upwards, allowing the measuring probe to enter the inner diameter of the stator winding. The inner measuring contact surface of the probe is then brought into contact with the inner wall of the stator winding, providing a precise measurement of its inner diameter. Furthermore, during the inspection of the inner and outer diameters of the stator winding, a rotating annular turntable can be used to coaxially rotate the stator winding, allowing for real-time readings of the digital caliper readings. This enables precise measurement of the inner and outer diameters at different locations, facilitating accurate measurement and positioning of the winding's limit values. This entire process not only improves measurement accuracy and consistency, effectively avoiding human error, but also significantly simplifies the measurement procedure, saves measurement time, and thus greatly enhances inspection efficiency.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1, as Figure 1-9 As shown, a tooling for detecting the size of the stator winding of a drive motor includes a base platform 1. An annular guide rail 2 and a lifting platform 3 are fixedly installed on the upper surface of the base platform 1. An annular turntable 4 is rotatably connected to the annular guide rail 2. Multiple positioning posts 5 are vertically fixedly installed above the annular turntable 4. The multiple positioning posts 5 are centrally symmetrically arranged and the center of symmetry coincides with the central axis of the annular turntable 4. A zero-alignment component 6 is detachably installed on the positioning posts 5.

[0033] A caliper mounting plate 7 is fixedly installed above the lifting platform 3. A caliper assembly 8 is installed on the side of the caliper mounting plate 7. The outer measuring contact surface of the caliper assembly 8 is in contact with the zero position surface of the zero correction assembly 6. The central axis of the annular turntable 4 is located in the vertical plane where the zero position surface of the zero correction assembly 6 is located.

[0034] In this embodiment, the caliper assembly 8 includes a caliper fixing shaft 81, a digital caliper 82, a linear slide rail 83, and a measuring plate 84. The caliper fixing shaft 81 and the linear slide rail 83 are both horizontally fixedly installed on the side of the caliper mounting plate 7. The caliper fixing shaft 81 and the linear slide rail 83 are parallel to each other. The digital caliper 82 is slidably connected to the caliper fixing shaft 81. The measuring plate 84 is slidably connected to the linear slide rail 83 through a sliding block 85. A measuring contact 86 is provided at the left end of the measuring plate 84. The left side of the measuring contact 86 is the outer measuring contact surface 861, and the right side of the measuring contact 86 is the inner measuring contact surface 862. A reading block 87 is fixedly installed at the right end of the measuring plate 84. The reading block 87 is in contact with the digital display block of the digital caliper 82.

[0035] Working principle:

[0036] In use, the digital caliper 82 is first zeroed. First, the zeroing component 6 is installed on the positioning post 5. Then, the annular turntable 4 is rotated to rotate the zeroing component 6, ensuring that the zero-position surface of the zeroing component 6 is aligned with the outer measuring contact surface 861 of the measuring contact 86 on the left end of the measuring plate 84. The measuring plate 84 is then slid to ensure the outer measuring contact surface 861 is fully in contact with the zero-position surface of the zeroing component 6. Next, the digital display block of the digital caliper 82 is brought into close contact with the reading block 87 on the right end of the measuring plate 84. The digital caliper 82 is then zeroed, thus achieving zero-position calibration. This indicates that the outer measuring contact surface 861 coincides with the vertical section in the front-back direction of the stator center, and the vertical center plane in the left-right direction of the measuring plate 84 coincides with the vertical section in the left-right direction of the stator center.

[0037] After zero-point calibration is completed, the zero-point calibration component 6 is removed from the positioning post 5, and then the stator winding to be tested is installed on the positioning post 5, so that the center of the stator winding coincides with the central axis of the annular turntable 4. Next, the measuring caliper 84 is slid so that the outer measuring contact surface 861 at the left end of the measuring caliper 84 is in contact with the outer surface of the stator winding. Then, the digital display block of the digital caliper 82 is brought into contact with the reading block 87 at the right end of the measuring caliper 84. At this point, the value displayed by the digital caliper 82 is the precise dimension of the stator winding's outer diameter. Then, by rotating the annular turntable 4, the stator winding can be rotated coaxially, and the changes in the value of the digital caliper 82 can be read in real time, thereby achieving precise measurement of the stator winding's outer diameter at different positions, and accurately measuring and locating the maximum value of the stator winding's outer diameter. It also enables comprehensive evaluation of key parameters such as the roundness and concentricity of the stator winding's outer diameter, ensuring the accuracy and consistency of the measurement data, facilitating subsequent processing and quality control.

[0038] When it is necessary to measure the inner diameter of the stator winding, the entire caliper assembly 8 can be raised by controlling the lifting platform 3, so that the entire measuring caliper plate 84 and the measuring contact 86 at its left end are higher than the stator winding. Then, the measuring caliper plate 84 is slid so that the measuring contact 86 is located in the inner ring of the stator winding. Then, the entire caliper assembly 8 is lowered by controlling the lifting platform 3 so that the measuring contact 86 enters the inner diameter of the stator winding. Then, the measuring caliper plate 84 is slid so that the inner measuring contact surface 862 of the measuring contact 86 is in contact with the inner wall of the stator winding. Then, the digital display block of the digital caliper 82 is brought into contact with the reading block 87 at the right end of the measuring caliper plate 84. At this time, the value displayed by the digital caliper 82 is added to the distance between the outer measuring contact surface 861 and the inner measuring contact surface 862 (i.e., the thickness of the measuring contact 86) to obtain the accurate size of the inner diameter of the stator winding. Subsequently, by rotating the annular turntable 4, the stator winding is driven to rotate coaxially, and the changes in the digital caliper 82 are read in real time. This allows for precise measurement of the inner diameter of the stator winding at different positions, enabling accurate measurement and positioning of the minimum value of the stator winding's inner diameter. During this process, it is crucial to ensure that the measuring contact 86 remains in close contact with the inner wall of the stator winding, and that the digital display block of the digital caliper 82 maintains stable contact with the reading block 87 on the right end of the measuring plate 84. This ensures the continuity and reliability of the measurement data, thereby accurately assessing key parameters such as the roundness and concentricity of the stator winding's inner diameter, providing a reliable basis for subsequent processing and quality control.

[0039] The aforementioned testing fixture enables precise and efficient measurement of the inner and outer diameters of the stator windings. This not only improves measurement accuracy and consistency, effectively avoiding human error, but also significantly simplifies the measurement process and saves measurement time, thereby greatly enhancing testing efficiency. It ensures that the quality of each stator winding meets high standards. Furthermore, the fixture has a reasonable structural design, is easy to operate, and is easy to maintain and service, effectively reducing operating costs and improving work efficiency.

[0040] Example 2, as Figure 3 As shown, in a further preferred embodiment, multiple support components are fixedly connected to the lower surface of the annular turntable 4 along its edge, and these support components are slidably connected to the annular guide rail 2. In this embodiment, each support component includes a support block 41 and a slider 42, which are fixedly connected or integrally formed. The support block 41 is fixedly mounted on the lower surface of the annular turntable 4, and the slider 42 is slidably connected to the annular guide rail 2. The multiple support components can be arranged in a centrally symmetrical manner, with the center of symmetry coinciding with the central axis of the annular turntable 4 and the annular guide rail 2, thereby ensuring that the annular turntable 4 remains stable during rotation and avoiding measurement errors caused by eccentricity. The symmetrical distribution of the support blocks 41 further enhances the stability of the structure, making the measurement process more accurate and reliable.

[0041] Example 3, as Figure 4 As shown, in a further preferred embodiment, the zero-position assembly 6 includes a positioning disk 61 and a zero-position plate 62. The positioning disk 61 has multiple mounting holes on its surface, and is connected to the positioning post 5 through these holes. The zero-position plate 62 is fixedly connected to the upper surface of the positioning disk 61 by screws. The side of the zero-position plate 62 is configured as a zero-position surface 621, which contacts the outer measuring contact surface 861 of the caliper assembly 8. Therefore, when the zero-position assembly 6 is installed onto the positioning post 5, the mounting holes on the surface of the positioning disk 61, in conjunction with the positioning post 5, enable rapid positioning and fixation of the zero-position assembly 6, ensuring that the zero-position surface 621 on the side of the zero-position plate 62 is horizontally aligned with the outer measuring contact surface 861.

[0042] In this embodiment, two positioning pins 63 are vertically fixedly installed on the upper surface of the positioning disk 61, and two positioning holes are opened on the bottom surface of the zero-position plate 62. The two positioning pins 63 are respectively inserted into the two positioning holes. Therefore, when the zero-position plate 62 is connected and fixed to the positioning disk 61, the two positioning pins 63 can precisely cooperate with the positioning holes on the bottom surface of the zero-position plate 62 to ensure that the zero-position plate 62 can be accurately positioned, avoid installation errors, and thus ensure the accuracy of the measurement reference.

[0043] Example 4, as Figure 2 As shown, as a further preferred embodiment, the base platform 1 has a clearance opening 11 on its surface, which is directly opposite to the center hole of the annular turntable 4. The clearance opening effectively avoids interference or obstruction of the stator winding to be measured, ensuring the smooth progress of the measurement process.

[0044] In addition, soft pads 12 are fixedly installed at the corners of the lower surface of the base platform 1. The soft pads 12 not only provide anti-slip function, but also effectively reduce vibration and noise during the measurement process, ensuring the accuracy and stability of the measurement data. Hand handles 14 are also provided on the left and right sides of the base platform 1. The hand handles 14 make it convenient for operators to move or adjust the position of the tooling, making the operation more convenient and efficient.

[0045] Example 5, as Figure 5 As shown, as a further preferred embodiment of the first embodiment, the lifting platform 3 includes a base plate 31 and a lifting top plate 32. The base plate 31 is fixedly installed on the upper surface of the base platform 1, and a base plate positioning hole 13 is provided on the upper surface of the base platform 1. The lower surface of the base plate 31 is inserted into the base plate positioning hole 13 through a base plate positioning pin. The base plate 31 and the lifting top plate 32 are connected by a scissor-type lifting mechanism. The caliper mounting plate 7 is fixedly installed on the upper surface of the lifting top plate 32.

[0046] More specifically, the scissor lift mechanism includes two sets of cross support assemblies and a lifting drive assembly. The two sets of cross support assemblies are respectively arranged on both sides above the base plate 31. Each set of cross support assemblies includes a first support plate 33, a second support plate 34, a third support plate 35, and a fourth support plate 36. The first support plate 33 and the second support plate 34 are cross-hung, and the third support plate 35 and the fourth support plate 36 are cross-hung. The upper surface of the base plate 31 is provided with first hinge plates 37 on both the left and right sides, and the lower surface of the lifting top plate 32 is provided with second hinge plates 38 on both the left and right sides. The surfaces of the first hinge plates 37 and the second hinge plates 38 are connected. Each of the eight surfaces is horizontally provided with a first strip hole 39 and a second strip hole 310. The lower end of the first support plate 33 is slidably connected to the first strip hole 39 via a sliding pin. The lower end of the second support plate 34 is rotatably connected to the first hinge plate 37 via a pin. The upper end of the third support plate 35 is rotatably connected to the second hinge plate 38 via a pin. The upper end of the fourth support plate 36 is slidably connected to the second strip hole 310 via a sliding pin. The upper end of the second support plate 34 and the lower end of the third support plate 35 are hinged together via a first cylinder 311. The upper end of the first support plate 33 and the lower end of the fourth support plate 36 are hinged together via a second cylinder 312.

[0047] The lifting drive assembly includes a first connecting plate 313, a second connecting plate 314, and a lead screw 315. The two ends of the first connecting plate 313 are fixedly connected to two first cylinders 311, and the two ends of the second connecting plate 314 are fixedly connected to two second cylinders 312. The first connecting plate 313 and the second connecting plate 314 are respectively provided with a first threaded hole and a second threaded hole in the middle. The threads of the first threaded hole and the second threaded hole are opposite in direction. The rear end of the lead screw 315 passes through the first threaded hole and the second threaded hole in sequence and is threadedly connected to the first connecting plate 313 and the second connecting plate 314. A handwheel 316 is fixedly installed at the front end of the lead screw 315.

[0048] Therefore, when the height of the entire caliper assembly 8 needs to be adjusted, simply turn the handwheel 316 to rotate the lead screw 315. Since the threads of the first and second threaded holes in the first connecting plate 313 and the second connecting plate 314 have opposite directions, the rotation of the lead screw 315 can cause the first connecting plate 313 and the second connecting plate 314 to move closer or further apart. This, in turn, can cause the first cylinder 311 and the second cylinder 312 to move closer or further apart, thereby affecting the upper ends of the first support plate 33 and the second support plate 34. As they move closer to or further apart, the lower ends of the third support plate 35 and the fourth support plate 36 also move closer to or further apart. At this time, the lower end of the first support plate 33 can slide relative to each other in the first slot 39 through a sliding pin, and the upper end of the fourth support plate 36 can slide relative to each other in the second slot 310 through a sliding pin. Since the first support plate 33 and the second support plate 34, and the third support plate 35 and the fourth support plate 36 are all connected by cross hinges, the scissor principle is used to achieve a smooth lifting and lowering movement of the entire caliper assembly 8 through the synchronous movement of the two sets of cross support components. At the same time, since the first support plate 33, the second support plate 34, the third support plate 35 and the fourth support plate 36 are connected by cross hinges, the entire lifting mechanism has a compact structure, occupies little space, and further improves the overall performance and practicality of the tooling.

[0049] In Example 6, as a further preferred embodiment of Example 1, multiple caliper positioning pins 71 are fixedly installed at the bottom of the caliper mounting plate 7, and positioning holes corresponding to the caliper positioning pins 71 are opened on the upper surface of the lifting platform 3. Therefore, when the caliper mounting plate 7 is fixed to the upper surface of the lifting platform 3, the caliper positioning pins 71 can be precisely aligned with the positioning holes on the upper surface of the lifting platform 3 to achieve precise positioning of the entire caliper mounting plate 7 in the left-right direction, thereby effectively ensuring that the vertical center plane of the measuring caliper plate 84 in the left-right direction coincides with the vertical section in the left-right direction where the center of the stator is located. This further ensures measurement accuracy.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
