[0002] In the motor manufacturing process, the magnetic tile is a key component, and its bonding strength with the motor core directly affects the motor's performance and stability. Existing methods for testing the strength of magnetic tiles have many shortcomings. Some testing equipment can only test each magnetic tile individually, resulting in low efficiency and difficulty in meeting the testing needs of large-scale production. Other equipment lacks sufficient testing accuracy, failing to accurately determine whether the bonding strength of the magnetic tile meets standards. This can easily lead to defective products entering the next process, increasing product quality risks and production costs. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to realize a motor magnetic tile bonding strength testing device that can efficiently and accurately detect the bonding strength of motor magnetic tiles.

[0004] The objective of this utility model is achieved through the following technical solution: A device for testing the bonding strength of motor magnetic tiles includes a testing platform and a control component. The device further includes a drive component, a guide rail component, and a clamping component slidably connected to the guide rail component. The drive component and the guide rail component are fixed to the testing platform. The clamping component is located below the drive component and moves up and down along the vertical direction of the guide rail component under the action of the drive component. The clamping component includes a mounting frame, a floating joint disposed on the mounting frame, multiple magnetic tile pressure rods, and elastic elements located on each magnetic tile pressure rod and abutting against both ends of each magnetic tile pressure rod. The multiple magnetic tile pressure rods are circumferentially arranged at the lower end of the mounting frame. The motor housing is located below the magnetic tile pressure rods. Multiple pressure sensors corresponding to the positions of the magnetic tiles are provided on the lower end face of the magnetic tile pressure rods for detecting the bonding strength of the magnetic tiles during the clamping process.

During the pressing process of the drive assembly, the floating joint allows for a certain range of eccentricity and angular deviation, enabling the cylinder and fixed upper plate to work stably and collaboratively even with assembly errors. The elastic element allows the pressure rods to move flexibly and finely adjust their angles within a certain range. When the magnetic tile surface is uneven or the heights of multiple magnetic tiles differ, the elastic element allows the magnetic tile pressure rods to adaptively conform to the magnetic tile surface, ensuring uniform pressure application and avoiding excessive or insufficient local force, thus ensuring accurate and reliable test results. The pressure sensor installed on the lower end face of the magnetic tile pressure rods can detect pressure data in real time and accurately during the pressing process.

[0020] Figures 1-2This utility model discloses a device for testing the bonding strength of motor magnetic tiles, comprising a testing platform 100 and a control component (not shown in the figure). The device further includes a drive component 200, a guide rail assembly 300, and a clamping component 400 slidably connected to the guide rail assembly 300. The drive component 200 and the guide rail assembly 300 are fixed on the testing platform 100. The clamping component 400 is located below the drive component 200 and moves up and down along the vertical direction of the guide rail assembly 300 under the action of the drive component 200. The clamping assembly 400 includes a mounting frame 401, a floating joint 402 disposed on the mounting frame 401, a plurality of magnetic tile clamping rods 403, and an elastic element 404 located on each magnetic tile clamping rod 403 and abutting against both ends of each magnetic tile clamping rod 403. The plurality of magnetic tile clamping rods 403 are circumferentially arranged at the lower end of the mounting frame 401, and the motor housing is located below the magnetic tile clamping rods 403. The lower end face of the magnetic tile clamping rods 403 is provided with a plurality of pressure sensors (not shown in the figure) corresponding to the position of the magnetic tile, which are used to detect the bonding strength of the magnetic tile during the clamping process.

[0021] Specifically, the control components are systems such as PLCs and industrial computers that can be applied to mechanical equipment control scenarios.

[0022] The drive assembly 200 is a cylinder that provides relatively stable thrust or pull force, ensuring that the clamping assembly 400 connected to it can move smoothly in a straight line.

[0023] The guide rail assembly 300 includes a slide rail 301 and a slider 302. The detection platform 100 includes a stiffener 105. The slide rail 301 is vertically fixed on the stiffener 105, and the slider 302 is slidably connected to the slide rail 301.

[0024] Mounting bracket 401 includes an adapter plate 4011, an upper plate 4012, a support column 4013, and a lower plate 4014. The upper plate 4012 is fixedly connected to the slider 302 through the adapter plate 4011, and the lower plate 4014 is fixedly connected to the upper plate 4012 through the support column 4013. Mounting bracket 401 also includes a connector fixing plate 4015, and the floating connector 402 is fixedly connected to the adapter plate 4011 through the connector fixing plate 4015.

[0025] The lower plate 4014 is provided with multiple mounting holes, and the clamping assembly 400 also includes a stop 405. The magnetic tile pressure rod 403 is located in the mounting hole and is fixed by the stop 405.

[0028] The testing platform 100 also includes a fixed lower plate 101, a fixed upper plate 102, and two sets of C-shaped frames 103 located between the fixed upper plate 102 and the fixed lower plate 101.

[0033] When the motor magnetic tile bonding strength detection device of the present application is in use, the motor housing with magnetic tiles is placed below the pressing component 400, and the control component controls the driving component 200 to work. The floating joint 402 drives the magnetic tile pressing rod 403 to move downward along the slide rail 301, and the pressure sensor on the lower end face of the magnetic tile pressing rod 403 contacts the magnetic tile and gradually applies pressure. During the pressing process, the pressure sensor transmits the collected pressure data to the control component in real time, and the control component compares the received data with the preset pressure threshold. If the pressure reaches the preset threshold and the magnetic tile does not show abnormal conditions such as falling off or displacement, it is determined that the bonding strength of the magnetic tile is qualified; if the magnetic tile falls off or is displaced when the pressure does not reach the preset threshold, or the magnetic tile shows abnormalities when the pressure continues to increase after reaching the preset threshold, it is determined that the bonding strength of the magnetic tile is unqualified. After the detection is completed, the pressing component 400 drives the magnetic tile pressing rod 403 to reset upward. The motor magnetic tile bonding strength detection device of the present application, through multiple circumferentially arranged magnetic tile pressing rods 403,配合压力传感器,能够实现对多个磁瓦的检测,大大提高了检测效率,满足大规模生产的检测需求;浮动接头402在驱动组件200下压过程中,允许一定范围内的偏心和角度偏差,使气缸和固定上板102在存在装配误差的情况下,仍能稳定协同工作;弹性件404允许磁瓦压杆403在一定范围内灵活移动和微调角度,当磁瓦表面不平整,或多个磁瓦高度有差异时,弹性件404可使磁瓦压杆403自适应贴合磁瓦表面,保证施加压力均匀,避免局部受力过大或过小,确保检测结果准确可靠;磁瓦压杆403下端面设置的压力传感器可以实时、精准地检测压紧过程中的压力数据,结合控制组件的数据分析和控制,能够准确判断磁瓦的粘接强度是否符合标准,提高了检测精度。
