[0023] Example
[0024] Please combine Figures 1 to 5As shown: This embodiment provides an automatic go gauge inspection device for motor cores, including a horizontally arranged fixture placement plate 1, and a core placement plate 2 horizontally arranged directly above the fixture placement plate 1. The core placement plate 2 is connected to a lifting mechanism 3, and the core placement plate 2 can move vertically up and down under the drive of the lifting mechanism 3. The core placement plate 2 is provided with a detection area adapted to the motor core 4 to be inspected (the marking is omitted in the figure, the part where the motor core 4 is placed is the detection area). The fixture placement plate 1 is provided with a go gauge fixture 5 located directly below the detection area. The go gauge fixture 5 is vertically provided with detection elements (detection inner diameter shaft 5-1, detection pin 5-2 and detection groove 5-3 shown in the figure) that correspond to and are adapted to the parts of the motor core 4 to be inspected (inner diameter hole 4-1, process hole 4-2 and process groove 4-3 shown in the figure). The detection area is provided with several through holes 2-1 for the detection elements to pass through.
[0025] In this invention, the core placement plate 2 and the go gauge fixture 5 can be replaced according to the specific structural shape of the motor core 4 to be tested. Therefore, the go gauge fixture 5 is detachably fixed on the fixture placement plate 1 so as to replace the corresponding go gauge fixture 5 according to the shape and size of the motor core 4 to be tested.
[0026] In this embodiment, taking the annular rotor as the motor core 4 to be tested as an example, the method of using the automatic go gauge testing device for motor cores described in this utility model is explained in detail:
[0027] like Figure 2 and Figure 3 As shown, the motor core 4 has an inner diameter hole 4-1 at its center. Multiple process holes 4-2 are arranged around the inner diameter hole 4-1. Multiple process grooves 4-3 are evenly distributed along the circumferential direction on the edge of the motor core 4. Correspondingly, the gauge fixture 5 is vertically provided with a detection inner diameter shaft 5-1, a detection pin 5-2, and a detection groove plate 5-3 that correspond to and are compatible with the inner diameter hole 4-1, process holes 4-2, and process grooves 4-3 of the motor core 4 to be tested (the inner diameter hole 4-1, process holes 4-2, and process grooves 4-3 are the parts of the motor core 4 to be tested). The detection area of the core placement plate 2 is provided with several through holes 2-1 for the detection inner diameter shaft 5-1, detection pin 5-2, and detection groove plate 5-3 to pass through.
[0028] Place the motor core 4 to be inspected into the inspection area of the core placement plate 2 (specifically, it can be positioned and placed into the inspection area of the core placement plate 2 by a robotic arm), so that the inner diameter hole 4-1, process hole 4-2, and process groove 4-3 of the motor core 4 correspond one-to-one with the inner diameter shaft 5-1, inspection pin 5-2, and inspection groove plate 5-3 of the go gauge fixture 5; start the lifting mechanism 3, and the core placement plate 2, together with the motor core 4, is driven downwards by the lifting mechanism 3. During the linear motion, as the motor core 4 descends, the inner diameter detection shaft 5-1, detection pin 5-2, and detection slot 5-3 on the gauge fixture 5 perform gauge checks on the inner diameter hole 4-1, process hole 4-2, and process slot 4-3 of the motor core 4, respectively. If the detection elements (inner diameter detection shaft 5-1, detection pin 5-2, and detection slot 5-3) can all pass smoothly through the corresponding parts to be detected on the motor core 4 (inner diameter hole 4-1, process hole 4-2, and process slot 4-3) (e.g.) Figure 4 and Figure 5 If the inner diameter hole 4-1, process hole 4-2, and process groove 4-3 are free of foreign objects and their dimensions meet the requirements, then the motor core 4 is a good product. Otherwise, the motor core 4 is a defective product.
[0029] After the inspection is completed, the iron core placement plate 2, together with the motor iron core 4, moves upward in a straight line to its original position under the drive of the lifting mechanism 3. The motor iron core 4 separates from the go gauge fixture 5, and then the inspected motor iron core 4 is removed by the robotic arm. The next motor iron core 4 to be inspected is then placed in the inspection area on the iron core placement plate 2. This process is repeated continuously, so that several motor iron cores 4 can be automatically inspected by go gauge. It has the advantages of high inspection efficiency and high degree of automation.
[0030] In this embodiment, vertically downward guide shafts 6 are respectively provided on both sides of the bottom of the iron core placement plate 2. The fixture placement plate 1 is provided with through holes 1-1 for the guide shafts 6 to pass through. A guide sleeve 7 adapted to the guide shaft 6 is vertically fixed at the bottom of the through holes 1-1. The upper end of the guide shaft 6 is fixedly connected to the bottom of the iron core placement plate 2, and the lower end of the guide shaft 6 is freely inserted into the guide sleeve 7. Through the provided guide shafts 6 and guide sleeves 7, the lifting and lowering movements of the iron core placement plate 2 and the motor iron core 4 on the iron core placement plate 2 can be guided, thereby ensuring that the iron core placement plate 2 and the motor iron core 4 on the iron core placement plate 2 can perform vertical linear movements.
[0031] In this embodiment, the lifting mechanism 3 is a vertically arranged lifting cylinder. The output end of the lifting cylinder 3 is connected to a horizontally arranged pressure plate 8. A vertically downward connecting plate 9 is fixedly provided at the front of the pressure plate 8. The iron core placement plate 2 is fixedly connected to the lower front side of the connecting plate 9 (preferably a detachable fixed connection, so as to facilitate the replacement of the corresponding iron core placement plate 2 according to the shape and size of the motor iron core 4 to be tested). During operation, the lifting cylinder 3 drives the pressure plate 8 to move up and down linearly, which in turn drives the connecting plate 9 to move up and down linearly, and in turn drives the iron core placement plate 2 and the motor iron core 4 on the iron core placement plate 2 to move up and down linearly.
[0032] In this embodiment, a slider 10 is fixedly mounted on the back of the connecting plate 9, and a vertically upward linear guide rail 11 is fixedly mounted on the rear of the fixture placement plate 1. The slider 10 is provided with a groove that matches the linear guide rail 11. During operation, the lifting cylinder 3 drives the pressure plate 8 to move up and down linearly, thereby driving the slider 10 connected to the connecting plate 9 to move up and down linearly along the linear guide rail 11, which in turn drives the iron core placement plate 2 and the motor iron core 4 on the iron core placement plate 2 to move up and down linearly. The slider 10 and the linear guide rail 11 can further guide the lifting and lowering movements of the iron core placement plate 2 and the motor iron core 4 on the iron core placement plate 2, thereby ensuring that the iron core placement plate 2 and the motor iron core 4 on the iron core placement plate 2 can move up and down linearly smoothly, and at the same time, effectively improving the stability of the iron core placement plate 2 and the motor iron core 4 on the iron core placement plate 2 moving up and down linearly.
[0033] In this embodiment, the automatic gauge inspection device further includes a frame 12, on which the lifting cylinder 3, linear guide rail 11, and fixture placement plate 1 are all mounted. Specifically, the main body of the lifting cylinder 3 is fixedly installed on the back of the frame 12, the linear guide rail 11 is vertically installed on the front of the frame 12, and the fixture placement plate 1 is horizontally installed in the middle of the frame 12 and located in front of the lower end of the linear guide rail 11.
[0034] Furthermore, the pressure plate 8 is T-shaped, and the top of the frame 12 has an opening 12-1 through which the longitudinal support arm 8-1 of the T-shaped pressure plate 8 passes (see [link]). Figure 5 As shown), during operation, the pressure plate 8 can move up and down linearly within the opening 12-1 under the drive of the lifting cylinder 3. Correspondingly, two linear guide rails 11 are vertically arranged on both sides of the opening 12-1.
[0035] Finally, it should be pointed out that the above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
