Description

Technical Field

[0001] This utility model belongs to the technical field of motor testing tools, and in particular relates to a novel integrated motor testing tool. Background Technology

[0002] In the manufacturing process of products such as transformers, new energy battery modules, and motor windings, the length tolerance of the lead wires, the position and shape of the coils (insulating sleeves or insulating sheets), and the integrity of the binding all require strict control. Traditional inspection uses a step-by-step approach: length measurement relies on calipers or segmented fixtures, and coil dimensions are checked manually by visual inspection or random sampling with simple clamps. This method has significant drawbacks:

[0003] Inefficient: Step-by-step operation prolongs the testing cycle and is difficult to match the production line rhythm;

[0004] Insufficient accuracy: Manual measurement is easily affected by operational errors, and minor offsets, twists or damages of the coil are easily missed;

[0005] Poor consistency: The relative positions of the coil and the lead wire (such as sleeve retraction and positioning lead wire position) lack quantitative evaluation standards.

[0006] While existing automation solutions (such as vision systems) can partially replace manual labor, they suffer from poor positioning stability when faced with flexible wire movement, wire coil reflection, or spatial obstructions, and struggle to simultaneously measure length and three-dimensional shape with high precision. Furthermore, dedicated equipment is costly to develop, lacks flexibility, and cannot adapt to multi-specification, small-batch production.

[0007] Therefore, there is an urgent need for an integrated, mechanical inspection tool to achieve rapid and accurate synchronous detection of lead wire length and coil parameters. Utility Model Content

[0008] The purpose of this utility model is to provide a new type of integrated motor inspection fixture, which solves the problems of low efficiency, poor accuracy, insufficient consistency, high labor cost and poor flexibility of traditional step-by-step inspection.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model is a novel integrated motor inspection fixture, comprising a stainless steel body and a rotating base vertically connected thereto;

[0011] The main body integrates a column-type scale and a coil detection area;

[0012] The column-type ruler is vertically fixed to one side of the upper end of the main body; the coil detection area is opened on both sides of the lower end of the main body, the outer diameter of the coil detection area is adapted to the standard size of the inner hole of the motor coil, and can rotate horizontally in the inner hole of the motor coil.

[0013] In one embodiment, the column-type ruler has a wall thickness of 5mm, a scale area length of 72mm, and a width of 10mm.

[0014] In one embodiment, the column-type scale is a stainless steel column with three etched graduation lines, and the accuracy of the graduation lines is ±2.5mm.

[0015] In one embodiment, the overall wall thickness of the body is 5mm, and the edges of both the body and the rotating base are chamfered.

[0016] In one embodiment, the rotating base is a circular platform with a detachable structure and is available in various diameters.

[0017] This utility model has the following beneficial effects:

[0018] 1. Improve testing efficiency and adapt to production line rhythm

[0019] The inspection fixture integrates lead wire length measurement and coil parameter detection into a single tool through its integrated design, eliminating the need for switching processes in traditional step-by-step inspections, significantly shortening the single inspection cycle, and quickly matching the fast-paced demands of the production line.

[0020] 2. Improve detection accuracy and reduce the risk of missed detections.

[0021] The column-type scale uses three-sided etched graduation lines (accuracy ±2.5mm), supports multi-angle readings, avoids the operational errors of manual caliper use, and ensures the accuracy of lead wire length measurement;

[0022] The coil detection area, with its structure adapted to the standard dimensions of the motor coil's inner hole and combined with a horizontal rotation detection method, can accurately identify minute offsets, twists, or damages in the coil, solving the problem of missed detection by traditional manual visual inspection or simple fixtures.

[0023] 3. Enhance testing consistency and quantify evaluation standards.

[0024] The inspection tool provides a unified quantitative inspection benchmark for the relative position of the coil and the lead wire (such as sleeve retraction and lead wire positioning), replacing the traditional qualitative judgment that relies on experience, reducing the inspection differences between different operators, and improving the stability of product quality.

[0025] 4. Optimize operational safety and convenience

[0026] Both the body and the rotating base have chamfered edges to prevent scratches to personnel or damage to motor leads during operation;

[0027] The column-type ruler features a three-sided scale design, making it convenient for operators to read data from different angles and reducing the difficulty of operation.

[0028] 5. Enhance flexibility and adaptability, and reduce costs.

[0029] The rotating base adopts a detachable structure and is equipped with a variety of diameter specifications to meet the testing needs of different motor models, without the need to develop special inspection tools for each specification.

[0030] Compared to automated vision systems, this inspection fixture has a simpler structure, lower cost, and is unaffected by factors such as wire swaying and coil reflection, resulting in higher inspection stability.

[0031] In summary, this integrated inspection fixture, through its integrated and standardized design, improves inspection efficiency, accuracy, and consistency while also ensuring operational safety and adaptability to multiple specifications. It effectively solves many pain points of traditional inspection methods and is suitable for multi-variety, small-batch motor production scenarios.
