Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle motor rotors, and in particular to a rotor thickness measuring mechanism. Background Technology

[0002] In the field of new energy vehicles, the drive motor is a core component. Its working principle is that the battery delivers electrical energy to the drive motor, generating electromagnetic force to drive the motor rotor to rotate, realizing the conversion of electrical energy into mechanical energy. Then, through components such as the reducer, the mechanical energy is transferred to the wheels to drive the vehicle. The drive motor rotor is mounted on the motor bearing housing. The thickness and dimensional accuracy of the rotor have a crucial impact on the motor performance. Therefore, it is essential to strictly confirm that the rotor thickness is within the acceptable accuracy range before assembly.

[0003] Currently, rotor thickness is typically measured manually using measuring instruments during production. However, this traditional method has significant drawbacks. Firstly, manual measurement is slow, making it difficult to meet the efficiency demands of large-scale production. Secondly, manual operation is affected by subjective factors and operator skill levels, making it difficult to guarantee measurement accuracy and precisely control rotor thickness dimensions, resulting in inconsistent product quality. Therefore, there is an urgent need to develop a device capable of rapid and automated measurement to improve the efficiency and accuracy of rotor thickness measurement and meet the high standards required for the production of drive motors for new energy vehicles.

The fully automatic production cycle time is only 36 seconds, which meets the process requirements and corresponding technical indicators and meets the requirements of mass production.

[0005] The objective of this utility model is achieved through the following technical solution:

[0007] The rotor is fixed on the support and limiting assembly and the thickness measuring assembly. The thickness measuring assembly is set in two sets, which are symmetrical and located on the left and right sides of the support and limiting assembly.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0022] In this embodiment, as Figures 1 to 3As shown, a rotor thickness measuring mechanism mainly consists of a support and limiting assembly and a thickness measuring assembly. The thickness measuring assembly includes two symmetrically arranged structures, each based on a base plate 1, on which a vertical plate 2 is fixedly fixed. A transverse cylinder 3 and two parallel linear slide rails 4 are installed on the front side of the vertical plate 2. A slider can slide on the linear slide rails 4. The output end of the transverse cylinder 3 and the slider together fix a slide block 5, allowing the slide block 5 to slide smoothly along the linear slide rails 4 under the drive of the cylinder. Three measuring heads 6 arranged in a triangular array at different horizontal heights are fixed on the slide block 5. The measuring heads 6 penetrate the outside of the slide block 5 to contact the rotor. Three first fixed seats 7 are provided inside the slide block 5 for mounting sensors. The inner end of the measuring head 6 abuts against the sensor output end to accurately transmit the measurement data. In addition, an airtight sensor 15 is installed on the front side of the slide block 5 to monitor the movement distance of the measuring head 6 and ensure the consistency of the measurement position.

[0023] In the support and limiting assembly, the upper end of the support base 8 is provided with a first groove, and the upper end of the second fixing seat 10 fixed on the opposite side of the switching support cylinder 9 is provided with a second groove. The two can work together to engage the rotor shaft. The positioning cylinder 11 on the support base 8 has a positioning pin 12 fixed at its output end that can be adapted to be inserted into the hole on the side of the rotor; the fastening cylinder 13 outside the switching support cylinder 9 has a fastening seat 14 at its output end that can abut against the outer end face of the rotor shaft. The multiple components work together to achieve stable positioning and clamping of the rotor.

[0024] Workpiece loading and initial positioning: The operator or automated loading equipment places the rotor to be measured onto the measuring unit. The positioning cylinder 11 is immediately activated, driving the positioning column 12 forward to insert into the hole on the side of the rotor. Through mechanical cooperation, the rotor's rotational freedom is restricted, and the initial positioning of the rotor is completed.

[0025] Precise support and fixation: The switching support cylinder 9 starts to operate, driving the second fixing seat 10 to move, so that the second groove is precisely aligned with the first groove on the support seat 8, together engaging the rotor shaft and supporting the rotor shaft from both ends. Immediately afterwards, the fastening cylinder 13 drives the fastening seat 14 forward, so that its side is tightly abutted against the outer end face of the rotor shaft, further fixing the rotor and ensuring that the rotor position is stable during the measurement process, without displacement or shaking.

[0026] Thickness measurement execution: The transverse cylinder 3 is activated, pushing the slide 5 to slide along the linear slide rail 4 towards the rotor, causing the measuring head 6 to gradually approach the rotor core surface. During this process, the airtightness sensor 15 monitors the movement distance of the measuring head 6 in real time. When the measuring head 6 moves to the set position, the airtightness sensor 15 detects that the sealing condition meets the standard and displays "OK", indicating that the measuring head 6 has accurately reached its position. At this time, the GT sensor installed on the first fixed seat 7 inside the slide 5 starts to work. The two sets of symmetrical measuring components simultaneously collect data. Based on the data obtained by the GT sensors at both ends, the thickness data of the rotor core is calculated through a pre-set algorithm.

[0027] Measurement Reset and Unloading: After measurement, the transverse cylinder 3 reverses its direction, causing the slide 5 and measuring head 6 to return to their initial positions. Subsequently, the fastening cylinder 13, the switching support cylinder 9, and the positioning cylinder 11 retract sequentially, releasing the fixing and positioning of the rotor. The operator or automated unloading equipment removes the measured rotor, completing the entire measurement process and preparing the equipment for the next measurement operation.

[0028] To address the issue of varying rotor sizes and shapes in the production of drive motors for new energy vehicles, this mechanism achieves flexible adaptation through the switching support cylinder 9. Different rotor models have different rotor shaft dimensions and positions. By controlling the extension, retraction, and rotation of the switching support cylinder 9, the position of the second fixed seat 10 can be adjusted, allowing the combination of the first and second grooves to accommodate the contours and installation requirements of different rotor shafts. Simultaneously, the action parameters of the positioning cylinder 11 and the fastening cylinder 13 can be preset and adjusted in the control system according to changes in the rotor model, ensuring stable positioning and accurate measurement of the rotor on the measuring mechanism regardless of the model, greatly improving the equipment's versatility and production applicability.

[0029] Each slide 5 has three measuring heads 6 arranged in a triangular pattern at different horizontal heights, enabling simultaneous measurement of the rotor from multiple positions. This design effectively avoids measurement errors caused by local unevenness or eccentricity of the rotor surface, obtaining more comprehensive and accurate rotor thickness data, and ensuring measurement accuracy through the layout of measurement points.

[0030] The precise coordination between the measuring head 6 and the GT sensor ensures accurate acquisition and transmission of measurement data. The measuring head 6 converts physical quantities such as displacement obtained from the contact rotor into signals that can be recognized by the sensor. The GT sensor performs high-precision processing on the signals and combines the data from the two sets of symmetrical measuring components to eliminate possible deviations in unilateral measurements, further improving the accuracy of the measurement results.

[0031] The airtight sensor 15 monitors the movement distance of the measuring head 6 in real time, ensuring that the contact pressure and position between the measuring head 6 and the rotor surface are consistent during each measurement. Even under conditions such as long-term continuous measurement or slight equipment vibration, the stability of measurement conditions can be ensured, thereby maintaining the consistency and reliability of measurement accuracy.

[0032] A core temperature measuring component is provided between the two sets of thickness measuring components. The core temperature measuring component is located below the support limiting component. The core temperature measuring component includes a mounting bracket 16, on which a cylinder 17 is fixed. A temperature measuring sensor 18 is fixed on the cylinder 17. The temperature measuring sensor 18 is used to detect the temperature of the core. The temperature measuring sensor 18 is moved by the cylinder 17 to detect the temperature of the incoming core, ensuring that the core is within a suitable temperature range and guaranteeing the consistency and accuracy of the thickness measurement results.
