[0018] A kind of permanent magnet installation equipment of outer rotor motor for industrial fan, including support seat 101 and rotary seat 103 being rotatably connected on support seat 101, multiple expansion frames 104 are uniformly fixedly connected with the periphery direction along the central axis of rotary seat 103 on the edge portion of rotary seat 103, and one clamping mechanism is respectively arranged on each expansion frame 104.

[0019] This part is according to Figures 1-8 The working process expressed in is as follows: when installing permanent magnet of outer rotor motor for industrial fan, in order to facilitate the adaptive rotation angle of motor shell for installing permanent magnet, to improve the accuracy of installing permanent magnet, improve overall installation efficiency;

[0020] When using, the motor shell opening to be installed permanent magnet is placed on rotary seat 103 upwards, the rotary connection position of rotary seat 103 and support seat 101 is relatively rough, so the user needs certain strength to rotate the motor shell on rotary seat 103, so that the motor shell on rotary seat 103 is rotated along the central axis of rotary seat 103 when rotary seat 103 rotates, to facilitate the angle of permanent magnet entering motor shell, to the best angle into motor shell, so as to facilitate the staff to install permanent magnet quickly, improve the accuracy of installing permanent magnet, improve overall installation efficiency;

[0021] When the motor shell placed on the rotating seat 103 is fixed and clamped, the clamping mechanism on each expansion frame 104 uniformly presses the motor shell clamped on the outer surface in the circumferential direction, so that the motor shell can be stably placed on the rotating seat 103, and the motor shell is fixed and limited.

[0022] The surface of the rotating seat 103 is uniformly provided with a plurality of anti-skid grooves.

[0023] This part is according to the working process expressed in Figures 1-8 The surface of the rotating seat 103 is uniformly provided with a plurality of anti-skid grooves, which facilitates to improve the friction between the surface of the rotating seat 103 and the motor shell, and maintain the stability of the motor shell placed on the rotating seat 103.

[0024] Each expansion frame 104 is made of stainless steel. The clamping mechanism includes a clamping disc 201 and a horizontal plate 202 fixedly connected to the rear side of the clamping disc 201. A plurality of horizontal plates 202 are respectively slidably connected to the upper sides of a plurality of expansion frames 104. One spring 203 is sleeved on one side of each horizontal plate 202. The two sides of each spring 203 are respectively fixedly connected to the corresponding horizontal plate 202 and expansion frame 104. Each spring 203 is a tensile spring. One handle is fixedly connected to the outer side of each horizontal plate 202.

[0025] This part is according to the working process expressed in Figures 1-8 When the clamping disc 201 arranged in the circumferential direction is used to clamp and fix the motor shell, the user holds the handle on the outer side of each horizontal plate 202 and pulls the horizontal plate 202 outward, so that the clamping disc 201 on the horizontal plate 202 moves outward synchronously, and the spring 203 sleeved on the horizontal plate 202 is stretched. After the motor shell is placed on the rotating seat 103, the handle on the outer side of each horizontal plate 202 is released, and each clamping disc 201 is clamped and pressed on the surface of the motor shell under the contraction force of each spring 203, so that the motor shell is pressed and clamped in the circumferential direction, and the stability of the motor is maintained.

[0026] The surface of each clamping disc 201 towards the side of the rotating seat 103 is respectively wrapped with a rubber pad.

[0027] This part is according to the working process expressed in Figures 1-8 When each clamping disc 201 is used to clamp and fix the motor shell, the rubber pad on one side surface of each clamping disc 201 is pressed on the surface of the motor shell, which prevents the motor shell from being directly pressed on the surface of the motor shell by the clamping disc 201, thereby protecting the motor shell by the wrapped rubber pad.

[0028] The bottom of the rotating seat 103 is fixedly connected to the chassis 105, and a vertically arranged rod is fixedly connected to one side of the chassis 105.

[0029] This section is based on Figures 1-8 The working process described is as follows: when the rotating seat 103 is rotated, thereby causing the motor housing on its surface to rotate, the user grasps the rod that is vertically set downward on one side of the chassis 105. The rod is fixedly connected to the chassis 105 by welding. After grasping the rod, the chassis 105 is rotated, thereby causing the rotating seat 103 and the motor housing on its surface to rotate and adjust the angle.

[0030] A right-angle bracket 102 is fixedly connected to the left side of the support base 101. A lifting base 301 is slidably connected to the upper side of the right-angle bracket 102. A pressing base 302 is slidably connected to the right side of the lifting base 301. A vertically arranged clamping plate is fixedly connected to the right side of the lifting base 301 and the right side of the pressing base 302 respectively. Rubber pads are adhered to the adjacent surfaces of the two clamping plates.

[0031] This section is based on Figures 1-8 The working process described is as follows: the movable end of the first electric push rod is fixedly connected to the left side of the pressing seat 302 via a flange; the fixed end of the first electric push rod is fixedly connected to the left side of the lifting seat 301 via a flange; the movable end of the second electric push rod is fixedly connected to the left side of the lifting seat 301 via a flange; and the fixed end of the second electric push rod is fixedly connected to the bottom left side of the right angle frame 102 via a flange.

[0032] When the permanent magnet is installed into the motor below, the first electric push rod is driven to move the pressing seat 302 located at its movable end. As a result, the clamping plate at the bottom of the pressing seat 302 moves toward the clamping plate on the lifting seat 301. The permanent magnet is further clamped by the two clamping plates. The rubber pads on each clamping plate can protect the permanent magnet during clamping and reduce the adhesion of impurities to the surface of the permanent magnet.

[0033] Furthermore, driving the second electric push rod causes the lifting seat 301 to lower the clamped permanent magnet, which then extends into the motor housing, facilitating the user's installation of the permanent magnet.
