The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.
The assembling device for the stop washer of the present embodiment, as shown in fig. 1-4, includes a pressing mechanism 2 and an operating mechanism 3 for controlling the pressing mechanism 2 to rotate and lift. The control mechanism 3 is used for controlling the pressing mechanism 2 to rotate to ascend or descend. Specifically, the control mechanism 3 includes a ball screw 31 and a ball screw nut 32 engaged with the ball screw 31. The ball screw nut 32 is screwed on the ball screw 31, and the pressing mechanism 2 is fixed on the ball screw nut 32, and the rotating and lifting of the pressing mechanism 2 are driven by the rotating and lifting of the ball screw nut 32.
The ball screw 31 is provided with an abutting portion 311 for abutting against the shaft body 11. The shaft body 1 is used for providing a supporting force for the ball screw 31, and the ball screw nut 32 can only spirally rotate along the ball screw 31 after the ball screw 31 is relatively fixed. The shaft body 11 is positioned in a mounting hole in the casing 1 by a bearing. In order to realize the installation and positioning of the bearing, a round nut 12 is screwed on the shaft body 11, and a stop washer 5 is arranged between the round nut 12 and the bearing for locking the round nut 12 to prevent the round nut 12 from rotating. In the present embodiment, the stopper washer 5 is provided with the plurality of bent portions 51 in the circumferential direction, and how to lock the round nut 12 by fitting the bent portions 51 in the direction of the round nut 12 in a limited space is an important issue.
In the present embodiment, an inclined open groove 21 for bending the bent portion 51 of the locking washer 5 is provided at an end of the pressing mechanism 2 away from the ball screw nut 32. When the pressing mechanism 2 rotates circumferentially, the inclined open slot 21 is driven to move towards the bent portion 51 to position the bent portion 51. The inclined open slot 21 is provided with an inclined guiding portion 211 and an arc-shaped limiting portion 212, when the pressing mechanism 2 rotates to a position opposite to the bending portion 51, the bending portion 51 enters the inclined open slot 21 along the inclined guiding portion 211, and the bending portion 51 abuts against the arc-shaped limiting portion 212 along with the rotation of the pressing mechanism 2, and further rotation of the pressing mechanism 2 enables the arc-shaped limiting portion 212 to generate an extrusion force on the bending portion 51 to drive the bending portion 51 to be partially curled and bent.
At this time, if the ball screw 31 is rotated to make the ball screw 31 control the pressing mechanism 2 to move upwards, the inner side wall of the inclined open slot 21 abuts against the bent portion 51 and drives the bent portion 51 to bend towards the direction close to the round nut 12.
