[0038] The lower fixing plate 134 and the lower positioning groove position gauge 135 are both ring structures, which facilitates the placement and removal of the stator core.
[0039] The upper positioning groove position gauge 111 is installed on the upper fixed plate 110, such as Figure 8 As shown, an upper rectangular spring 113 is installed between the top of the upper positioning groove position gauge 111 and the bottom of the upper fixed plate 110.

[0043] The steel ball guide post and the steel ball guide sleeve work together to guide the downward movement of the upper detection component and ensure its stable downward movement.
[0044] A discharge plate 118 is coaxially arranged on the lower inner side of the upper positioning groove position gauge 111, such as...

[0045] The upper connecting seat has a through hole for the guide post of the unloading plate to pass through, so that the unloading plate has enough compression space.
[0046] During testing, the unloading plate and the support platform work together to clamp the stator core. After the test is completed, the upper testing assembly is raised as a whole. Under the reaction force of the second compression spring, the unloading plate is separated from the stator core, and the unloading plate is reset at the same time, which facilitates the subsequent removal of the stator core.
[0047] An alarm 106 is installed on the top of the rack 101. The controlled end of the alarm 106 is connected to the output end of the controller, and can issue a prompt in time when the position degree detection fails.
[0048] In use, firstly, the through-beam sensor transmits and receives signals to check if there is a product on the carrier platform. If there is no product, the stator core to be tested is placed on the carrier platform by the automatic conveying mechanism, and the stator core is accurately positioned by the stator slot positioning block.
[0049] Next, the servo cylinder is controlled to push the upper fixed plate down, and the upper positioning groove position gauge and the steel ball guide post move down synchronously. During the downward movement, the upper detection component and the lower detection component are accurately closed by the cooperation of the steel ball guide post and the steel ball guide sleeve. At this time, the unloading plate and the bearing platform cooperate to clamp the stator core.
[0050] Then, the downward servo cylinder is controlled to continue moving downward to detect the position of the positioning slot on the stator, while the upward servo cylinder is lifted upward to detect the position of the lower positioning slot on the stator.
[0051] During the inspection process, if the locking block inside the fixture can be smoothly inserted into the stator positioning slot without any jamming, it indicates that the position of the stator positioning slot is qualified. If the position of both the upper and lower positioning slots is qualified, a qualified inspection signal is sent to the controller. At the same time, the controller drives the upper and lower inspection components to reset. Then, the stator core on the carrier platform is removed and moved to a suitable work position by the automatic conveying mechanism.
[0052] If the locking block inside the fixture cannot be smoothly inserted into the stator positioning slot during the inspection process, the fixture moves down with the help of the fixture guide post. During the downward movement, the fixture gradually compresses the probe of the contact sensor. When the compression of the contact sensor probe exceeds the preset threshold, the position accuracy of the stator positioning slot is automatically determined to be unqualified, and an unqualified signal is sent to the controller. The controller drives the upper and lower detection components to automatically reset, and then the stator core on the carrier platform is removed and moved to a suitable work position by the automatic conveying mechanism.
[0053] During the testing process, key data such as the measured position accuracy of the stator positioning slot, the pass / fail judgment results, the testing time, work order information, and the product serial number are automatically uploaded, stored, and classified for archiving, forming a complete digital data storage chain. This solves the pain points of existing technologies, such as the inability to archive data for extended periods and the difficulty in traceability. Simultaneously, data can be queried and traced with a single click by batch, work order, or serial number, meeting the requirements of quality system control and customer factory audits.
[0054] This invention provides a stator positioning slot position measurement device. It accurately measures the position of the stator core using upper and lower detection components. A controller coordinates the entire measurement process, completing a closed-loop operation of loading, measurement, data upload, and unloading. This achieves fully automated real-time online measurement of the stator positioning slot position. The measurement speed precisely matches the automated production line's cycle time. The measurement process requires no manual intervention or production line interruption, effectively eliminating the efficiency bottleneck caused by manual measurement, significantly improving the overall line uptime, meeting the measurement needs of continuous batch production, and solving the core pain point of existing technologies being unable to adapt to online synchronous measurement.
[0055] The upper and lower positioning detection components clamp the stator core through the cooperation of the bearing platform and the unloading plate. The setting of the inspection fixture can unify the detection benchmark and judgment standard. With the help of the contact displacement sensor, it can accurately identify products with out-of-tolerance position and upload and record the data to achieve accurate detection, reduce the intensity of manual labor, and its detection accuracy, repeatability and consistency are significantly better than manual detection.
