The bottom end of the support shaft 21 is rotatably mounted with an annular sleeve 22 via a bearing. This bearing can simultaneously withstand radial and axial loads, ensuring stable rotation of the annular sleeve 22. The inner wall of the annular sleeve 22 is provided with a linear guide rail, which forms a sliding pair with the slider on the sliding block 24, enabling smooth linear sliding of the sliding block 24. The annular sleeve 22 is located above the rotating plate 3. The short shaft 32 and the sliding block 24 are rotatably connected via a spherical bearing, enabling flexible rotation in multiple directions. The electrical components in this application are electrically connected to their compatible power supply via wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The detailed connection methods are known in the art.

[0021] A motor 31 is installed at the bottom of the base 1 and near the center of one side. The output end of the motor 31 passes through the base 1 and is fixedly connected to the rotating plate 3.

[0022] By adopting the above technical solution, the control terminal of motor 31 is connected to an external PLC control system, which can realize automated program control and adjust the position of placement plate 25 according to actual usage requirements.

[0023] A press body 2 is provided at the bottom of the L-shaped plate 11 and near the support shaft 21, and the press body 2 and the center of the placement plate 25 are at the same level.

[0024] By adopting the above technical solution, the stamping press body 2 can be a hydraulic stamping press, equipped with a high-precision pressure sensor and displacement sensor, which can monitor the stamping pressure and stroke in real time.

[0025] A slot 26 is provided at the center of the top of the placement plate 25.

[0026] By adopting the above technical solution, the card slot 26 is adapted to the card plate 27, which facilitates the placement of the card plate 27 with different placement circular slots 28 inside the card slot 26.

[0027] A card plate 27 is provided at the top of the placement plate 25 and at the card slot 26.

[0028] By adopting the above technical solution, the card plate 27 is set in order to set multiple different placement slots 28 so as to place commutators of different sizes and types.

[0029] A circular groove 28 is provided at the center of the top of the card plate 27.

[0030] By adopting the above technical solution, the placement grooves 28 opened inside different card plates 27 are different, thereby realizing the stamping of commutators of different models and sizes.

[0031] Limiting holes 12 are provided inside the card plate 27 near the corners, and limiting holes 23 are provided at the bottom of the card slot 26 near the corners.

[0032] By adopting the above technical solution, the limiting hole 12 and the limiting hole 13 are matched to facilitate the use of bolts or locking shafts to achieve the effect of limiting the locking plate 27.

[0033] The base 1 has symmetrically fixed handles at both ends near the center.

[0034] By adopting the above technical solution, symmetrical handling handles are set on both sides of the base 1 to facilitate the user's handling of the equipment.

[0035] Working principle: When using this device, first place the hook-type commutator to be stamped in the placement groove 28 on the clamping plate 27, then start the motor 31, which causes the fixedly connected rotating plate 3 to rotate. In conjunction with the short shaft 32 and the sliding block 24, the annular sleeve 22 rotates under the action of the support shaft 21, thereby driving the placement plate 25 to rotate. After the hook-type commutator in the placement plate 25 moves to the bottom of the stamping machine body 2, the stamping work of the commutator can be completed by the stamping machine body 2. (Because there is a certain distance between the placement plate 25 and the base 1, a pad can be placed at the top of the base 1 and at the same level as the stamping machine body 2 to facilitate the stamping of the commutator). After the stamping is completed, run the motor 31 again to facilitate the removal of the commutator located below the stamping machine body 2 after the work is completed, thereby improving the safety of the equipment during use.

[0036] When stamping commutators of different sizes and models, the limiting shaft or bolt between the two sets of limiting holes 12 and 13 can be removed first, and then the retaining plate 27 in the retaining groove 26 can be removed and replaced. After that, the replaced retaining plate 27 is placed in the retaining groove 26, and then the limiting shaft or bolt is set between the two sets of limiting holes 12 and 13. This can improve the practicality of the equipment during use.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
