[0034] The features and performance of the motor nut auxiliary installation tool of the present application will be further described in detail below in conjunction with embodiments.

[0035] Such as Figure 1 、 Figure 2 、Figure 3 and Figure 4 As shown in Figure 4 , an embodiment of the present application provides an auxiliary installation tool for a motor nut, which is used to install a nut 520 on the output shaft of a motor assembly 500 to define the position of a motor spring 510 sleeved on the output shaft of the motor assembly 500. The tool includes a T-shaped bracket 100, a motor support seat 200 that is liftably connected to the top of the bracket 100, a pair of pressing rods 300 that are liftably and rotatably connected to the bracket 100 along a horizontal plane, and a driving mechanism 400 for driving the pair of pressing rods 300 to lift and rotate along the horizontal plane;

[0036] Among them, a threaded hole 110 is provided at the center of the top of the bracket 100, and a connection hole 120 penetrating the bracket 100 is provided on each side of the top of the bracket 100. The bottom of the motor support seat 200 is connected to the threaded hole 110 through a stud 230 with an external thread. When the motor support seat 200 rotates, it moves up and down relative to the bracket 100. A motor positioning groove 210 for clamping the bottom of the motor assembly 500 is provided at the top of the motor support seat 200. When the bottom of the motor assembly 500 is clamped in the motor positioning groove 210, the output shaft is arranged vertically upward. A V-shaped groove 220 is provided on the outer wall of the motor support seat 200 at intervals along its circumference;

[0037] Each pressing rod 300 includes an inverted L-shaped pressing portion 310, a cylindrical sliding portion 330, and a rectangular cross-section hinge portion 320 connected in sequence. The sliding portions 330 of the two pressing rods 300 respectively slide through the connection holes 120 provided on both sides of the top of the bracket 100. Shaft holes 370 are provided on the hinge portions 320 of the two pressing rods 300. When the pressing rod 300 descends or ascends, the sliding portion 330 moves along the corresponding connection hole 120 and drives the pressing portion 310 and the hinge portion 320 to press against the top and bottom of the bracket 100 to define the lifting height. When the pair of pressing rods 300 rotate to a preset position along the horizontal plane and then lift, they stop pressing or press against both sides of the top of the motor spring 510 on the output shaft of the motor assembly 500 clamped in the motor positioning groove 210; A pin 350 is connected to the pressing portion 310 of the pressing rod 300 through a pin hole 360. A return spring 340 is sleeved on the pressing portion 310 of the pressing rod 300, and both ends of the return spring 340 respectively press against the pin 350 and the bracket 100. The return spring 340 is used to drive the lowered pressing rod 300 to reset.

[0038] The driving mechanism 400 includes two handles 410 corresponding to the pressure rods 300 one by one. Connection grooves 420 corresponding to the hinge portions 320 of the pressure rods 300 are respectively provided at the tops of each handle 410. The hinge portions 320 of the two pressure rods 300 respectively extend into the connection grooves 420 of the corresponding handles 410 and are hinged to the corresponding handles 410 through a connection shaft 430. Chamfers 440 are respectively provided on the side walls of the two handles 410 facing each other. When the handles 410 rotate to the vertical position in the vertical plane and press against the top of the bracket 100, the chamfers 440 rotate away from the bracket 100 and drive the corresponding pressure rods 300 to descend and press against the top of the motor spring 510. When the handles 410 rotate in the horizontal plane, the corresponding pressure rods 300 are driven to rotate in the horizontal plane.

[0039] The working process of the motor nut auxiliary installation tool provided by the embodiment of the present application is as follows: The user fixes the bracket 100 on the workbench, and then holds the bottoms of the two handles 410 with both hands and rotates along the horizontal plane. The two hinged pressure rods 300 are driven by the two handles 410 to rotate along the horizontal plane, so that the tops of the inverted L-shaped pressing parts 310 of the two pressure rods 300 rotate away from the motor support seat 200 at the top of the bracket 100. Then, the motor support seat 200 is rotated so that the stud 230 connected to the bottom of the motor support seat 200 moves downward along the threaded hole 110 until the bottom of the motor support seat 200 presses against the top surface of the bracket 100. Next, the bottom of the motor assembly 500 to be installed is clamped in the motor positioning groove 210 at the top of the motor support seat 200, so that the output shaft of the motor assembly 500 to be installed is arranged vertically upward and is sleeved with a motor spring 510. Then, the user holds the bottoms of the two handles 410 with both hands and rotates in the opposite direction along the horizontal plane. The two hinged pressure rods 300 are driven by the two handles 410 to rotate in the opposite direction along the horizontal plane, so that the tops of the inverted L-shaped pressing parts 310 of the two pressure rods 300 rotate to both sides of the top of the motor spring 510 sleeved on the output shaft of the motor assembly 500 to be installed. The user holds the two handles 410 with both hands and rotates them towards each other to a vertical position to press against the bottom of the bracket 100, so that the chamfers 440 of the two handles 410 rotate away from the bracket 100 respectively and drive the two pressure rods 300 to descend to press against both sides of the top of the motor spring 510 on the output shaft of the motor assembly 500 clamped in the motor positioning groove 210. Observe the compression condition of the motor spring 510 on the output shaft of the motor assembly 500. If the motor spring 510 is not fully compressed, rotate the handles 410 in the opposite direction away from each other so that the chamfers 440 rotate towards the bracket 100 respectively, and drive the two pressure rods 300 to rise to stop pressing the motor spring 510. Rotate the motor support seat 200 to adjust the height of the motor assembly 500 and the motor spring 510 it supports until the two handles 410 rotate towards each other to a vertical position to press against the bottom of the bracket 100 and drive the two pressure rods 300 to just fully compress both sides of the top of the motor spring 510 in place. Then, the corresponding nut 520 can be installed on the output shaft of the motor assembly 500 to limit the position of the motor spring 510. Then, the user can hold the bottoms of the two handles 410 with both hands and rotate along the horizontal plane. The two hinged pressure rods 300 are driven by the two handles 410 to rotate along the horizontal plane, so that the tops of the inverted L-shaped pressing parts 310 of the two pressure rods 300 rotate to stop pressing the motor spring 510. Take out the installed motor assembly 500, and the installation of the nut 520 of the motor assembly 500 is completed.

[0040] Among them, a motor positioning groove 210 for clamping the bottom of the motor assembly 500 is provided at the top of the motor support base 200, which can stably fix the motor assembly 500 to the motor support base 200, so as to facilitate positioning and using a pair of pressure rods 300 to press down the motor spring 510 sleeved on the output shaft of the motor assembly 500 to facilitate the installation of the nut 520; V-shaped grooves 220 are arranged at intervals along the circumferential direction on the outer wall of the motor support base 200, which is convenient for the user to stably rotate the motor support base 200 to adjust the height; a return spring 340 with two ends respectively pressing against the pin 350 and the bracket 100 is sleeved on the pressing portion 310 of the pressure rod 300, and the return spring 340 is used to drive the lowered pressure rod 300 to reset. When the user rotates the handle 410 to stop pressing down the pressure rod 300 after installing the nut 520, the compressed return spring 340 can be used to push the lowered pressure rod 300 to move reversely and rise to reset.

[0041] In other alternative embodiments, the motor support base 200 can also be connected to the bracket 100 in a liftable manner through a lifting mechanism, and the lifting mechanism can be an electric push rod or other mechanisms that can drive the motor support base 200 to lift relative to the bracket 100.

[0042] In other alternative embodiments, the driving mechanism 400 can also be other mechanisms that can drive the pressure rod 300 to rotate and lift along the horizontal plane. For example, the driving mechanism 400 can also include a lifting mechanism for driving the pressure rod 300 to lift and a rotating motor for driving the corresponding lifting mechanism and the pressure rod 300 to rotate along the horizontal plane. At this time, the output shaft of the lifting motor is arranged vertically and connected to the bottom of the pressure rod 300, and the lifting mechanism is an electric push rod fixed to the bracket 100 and connected to the lifting motor.
