[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 1 As shown, a magnetic slot length and width detection device for rotor production includes a device body, which includes a connecting frame 2, a detection mechanism and a placement mechanism;

[0017] The detection mechanism includes two first guide rails 31 and a first cylinder 32 symmetrically mounted on the connecting frame 2. A lower pressing frame 33 is slidably arranged on the first guide rail 31. The bottom of the lower pressing frame 33 has a pressing plate 331. A second cylinder 34 is mounted on the lower pressing frame 33. The piston rod of the second cylinder 34 has a through gauge 35. The first cylinder 32 is fixedly connected to the connecting frame 2, and the lower pressing frame 33 is fixed on the piston rod of the first cylinder 32.

[0018] The placement mechanism includes a pallet rack 41, a first pallet 42 and a servo motor 43. The pallet rack 41 is fixed on the connecting rack 2. Third cylinders 44 are symmetrically arranged on both side frames of the pallet rack 41. The first pallet 42 is commonly fixed on the piston rods of the third cylinders 44. A workpiece 5 is placed on the first pallet 42. The servo motor 43 is installed at the bottom of the pallet rack 41 and connected to the workpiece 5.

[0019] The output shaft of the servo motor 43 can be connected to the workpiece 5 for rotating and resetting the workpiece 5 .

[0020] In the present invention, the general gauge 35 is a prior art and is used for mass inspection of products.

[0021] With the above structure, the workpiece 5 is placed on the tray by the transfer tool and then left. This transfer tool is a prior art and is used to place the workpiece 5 or remove the workpiece 5 after inspection. Subsequently, the first cylinder 32 is started. The first cylinder 32 is a lifting cylinder for lifting the lower pressure frame 33. The first cylinder 32 gives a downward thrust to the lower pressure frame 33. At the same time, the moving direction of the upper and lower pressure frames 33 of the first guide rail 31 is consistent with the pushing direction of the first cylinder 32, which is conducive to quickly pushing the lower pressure frame 33 to the top of the workpiece 5 on the first tray 42, and the pressure plate 331 located at the bottom of the lower pressure frame 33 presses the workpiece 5, which is conducive to preventing the workpiece 5 from falling. At the same time, the through gauge 35 is pushed downward by the second cylinder 34. A plurality of magnetic grooves are pre-opened on the workpiece 5. If the through gauge 35 cannot pass through the plurality of magnetic grooves on the workpiece 5, a proximity opening is also provided on the device body. The first cylinder 32 is then moved upward and the servo motor 43 provided at the bottom of the tray rack 41 is started to drive the workpiece 5 to rotate a predetermined angle, and then the first cylinder 32 is started again to repeatedly press the lower pressing rack 33, and at the same time, the pressing plate 331 presses the workpiece 5 again to prevent it from falling, and the second cylinder 34 pushes the through gauge 35 downward again, so that the through gauge 35 tries to pass through several magnetic grooves on the workpiece 5 again. If it can still pass through several magnetic grooves on the workpiece 5, it can be determined that the workpiece 5 is a qualified workpiece 5, and then the first cylinder 32 is moved upward and opened, so that there is a gap between the lower pressing plate and the workpiece 5 on the tray, and the servo motor 43 resets the workpiece 5 that has been rotated before, waiting for the transplanting tooling to take the workpiece 5 away again.

[0022] The arrangement of this structure is conducive to the reuse of the through gauge 35, multiple clamping of the workpiece 5 and multiple inspections, with high inspection accuracy and better inspection quality, which greatly improves the product quality of the workpiece 5 when it is produced; at the same time, the clamping plate can hold the workpiece 5 during inspection, which is conducive to preventing the workpiece 5 from falling and effectively protecting the workpiece 5.

[0023] Specifically, if Figure 1As shown, a workpiece 5 is arranged directly below the through gauge 35 .

[0024] With the above structure, when the lower pressing frame 33 is moved downward, the second cylinder 34 drives the through gauge 35 to align with the workpiece 5, which is conducive to better detection of whether the workpiece 5 is qualified and has higher detection accuracy.

[0025] like Figure 1 As shown, the through gauge 35, the workpiece 5 and the output shaft of the servo motor 43 are located on the same axis. This structure is conducive to synchronizing the workpiece 5 on the output shaft of the servo motor 43 when pushing the through gauge 35 and the pressure plate 331 upward or downward, preventing detection errors caused by angle tilt offset, and achieving higher detection accuracy.

[0026] like Figure 1 As shown, a plurality of detection parts are arranged around the center of the through gauge 35, with the center of the through gauge 35 as the center of the circle. By providing a plurality of detection parts, it is beneficial to better detect the workpiece 5, and the detection efficiency and accuracy are higher.

[0027] like Figure 1 As shown, the first tray 42 has protrusions 421 on both sides, and the piston rod of the third cylinder 44 abuts against the protrusions 421 of the first tray 42 .

[0028] By the piston rod of the third cylinder 44 abutting against the protrusion 421, while the first cylinder 32 pushes the pressure plate 331 downward, the third cylinder 44 slightly pushes the first pallet 42 downward, which is beneficial to fine-tune the first pallet 42 downward and prevent the first cylinder 32 from giving too much thrust to the pressure plate 331, which causes excessive pressure on the workpiece 5, which is beneficial to protecting the workpiece 5 and improving the processing quality of the workpiece 5.

[0029] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. At the same time, the meaning of "and / or" appearing in the full text is that it includes three schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
