[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] 1. In this utility model, guide rails are installed on both sides of the base, and movable seats are set on the guide rails. A bracket is installed on the top of the movable seats, and a fixed plate is set on the top of the base. The two sides of the fixed plate are slidably sleeved on the bracket. At the same time, an electric telescopic rod is installed on the top of the bracket and fixedly connected to the end of the fixed plate to control the up and down movement of the fixed plate. When stamping the rotor lamination, the lamination is placed into the forming groove on the base. At this time, the electric telescopic rod drives the fixed plate to move down, and cooperates with the base to press the lamination into the forming groove. Then the rotor punch moves down and passes through the fixed plate to complete the stamping. This can maintain the stability of the rotor lamination during the stamping process and avoid the rotor lamination from errors caused by mechanical vibration during the stamping process.

The electric telescopic rod drives the fixed plate to move upward, and at the same time, the driving component is activated, driving the transmission component to rotate. The rotation of the transmission component drives the movable seat to move. The movement of the movable seat drives the fixed plate to move through the bracket, so that the fixed plate moves above the material rack on one side. Then, the arc-shaped electromagnets are de-energized, so that the rotor lamination automatically falls onto the material rack, completing the automatic unloading of the rotor lamination, further increasing the production efficiency of the rotor lamination.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example 1

[0023] Combination Figure 1-4 As shown, this embodiment provides a rotor lamination fixing structure, including: a main body mechanism 100.

[0024] The main structure 100 includes a base 110, a rotor punch 120 disposed above the base 110, guide rails 130 symmetrically mounted on both sides of the base 110, a transmission component 140 mounted in the inner cavity of the guide rails 130, a drive component 150 mounted on one end of the guide rails 130 and extending into the guide rails 130 and meshing with the transmission component 140, a movable seat 160 slidably disposed on the guide rails 130 and extending into the guide rails 130, a bracket 170 fixed on the movable seat 160, a fixed plate 180 movably sleeved on the bracket 170 at both ends, and an electric telescopic rod 190 mounted on the top of the bracket 170 and fixedly connected to the bottom of the fixed plate 180. The top of the base 110 has a forming groove 111, and a positioning post 112 is fixed in the middle of the inner bottom wall of the forming groove 111 for positioning the rotor laminations to be stamped. The rotor punch 120 is used to stamp and form the rotor laminations.

[0025] The guide rail 130 is used to mount the movable seat 160 and limit the movement of the movable seat 160. A groove 131 is opened on one side of the guide rail 130. The transmission component 140 includes a threaded rod 141 mounted on the inner wall of the groove 131 and a first bevel gear 142 fixed to the end of the threaded rod 141. Meanwhile, the movable seat 160 includes a slide 161 slidably mounted on the guide rail 130 and a threaded sleeve 162 fixed on the inner side of the slide 161 and extending into the groove 131. The threaded rod 141 passes through the threaded sleeve 162 and meshes with the threaded sleeve 162, so that when the threaded rod 141 rotates, it can drive the threaded sleeve 162 to move. The movement of the threaded sleeve 162 drives the slide 161 to move, and then drives the fixed plate 180 to move through the bracket 170.

[0026] In addition, symmetrical grooves 132 are provided at the top of the guide rail 130, and symmetrical sliders 1611 are fixed on the inner side of the slide block 161. The sliders 1611 are fitted into the grooves 132 to ensure the stability of the slide block 161 when it moves.

[0027] The driving component 150 is used to drive the transmission component 140 to rotate. It includes a motor 151 fixed to the end of the guide rail 130 and with its shaft extending into the inner cavity of the guide rail 130, and a second bevel gear 152 fixed on the shaft of the motor 151. The second bevel gear 152 meshes with the first bevel gear 142. When the motor 151 starts, it drives the second bevel gear 152 to rotate. The rotation of the second bevel gear 152 drives the first bevel gear 142 to rotate. The rotation of the first bevel gear 142 drives the threaded rod 141 to rotate.

[0028] The bracket 170 is used to install the fixed plate 180 and limit the movement of the fixed plate 180. The bottom end of the electric telescopic rod 190 is fixedly connected to the end of the fixed plate 180 and is used to drive the fixed plate 180 to move up and down.

[0029] The fixed plate 180 moves under the drive of the electric telescopic rod 190 to press the rotor laminations placed in the forming groove 111, ensuring the stability of the rotor laminations during stamping and avoiding errors caused by mechanical vibration during stamping.

[0030] A slot 181 is provided on the fixed plate 180 to facilitate the rotor punch 120 passing through the fixed plate 180 to punch the rotor laminations. Multiple arc-shaped electromagnets 182 are installed in a circular array at the bottom end of the fixed plate 180, and the bottom end face of the arc-shaped electromagnets 182 is flush with the bottom end face of the fixed plate 180. After the rotor laminations are punched, the arc-shaped electromagnets 182 are energized, which can attract the rotor laminations onto the fixed plate 180, making it convenient to move them to the top of the material rack later.

[0031] The working principle and usage process of this utility model are as follows: During use, the rotor lamination to be stamped is placed in the forming groove 111 on the base 110. At this time, the electric telescopic rod 190 is activated, driving the fixed plate 180 to move downwards. The downward movement of the fixed plate 180, in conjunction with the base 110, presses the rotor lamination tightly into the forming groove 111, ensuring the stability of the rotor lamination. Then, the rotor punch 120 moves downwards and passes through the slot 181 on the fixed plate 180 to stamp the rotor lamination. After stamping, the electromagnet is energized, attracting the stamped rotor lamination onto the fixed plate 180. The electric telescopic rod 190 retracts, driving the fixed plate 180 upwards... The fixed plate 180 moves upward, causing the rotor laminations to move upward. At the same time, the motor 151 starts, driving the second bevel gear 152 to rotate. The rotation of the second bevel gear 152 drives the first bevel gear 142 to rotate. The rotation of the first bevel gear 142 drives the threaded rod 141 to rotate. The rotation of the threaded rod 141 drives the threaded sleeve 162 to move. The movement of the threaded sleeve 162 drives the slide 161 to move. The movement of the slide 161 drives the fixed plate 180 to move through the bracket 170, so that the fixed plate 180 moves to the top of the material rack on one side. At this time, the arc electromagnet 182 is de-energized and loses its magnetic force. The rotor laminations automatically fall onto the material rack, completing the automatic unloading of the rotor laminations.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
