Embodiment 1

[0047] see figure 1 with figure 2As shown, a step-by-step assembly device for flange nuts in Embodiment 1 of the present application includes a sleeve 1, a first elastic mechanism 2, a second elastic mechanism 5, and a push-pull mechanism 4, and a sleeve 1 is opened through the sleeve. 1, the first elastic mechanism 2 and the second elastic mechanism 5 are arranged up and down along the length direction of the sleeve 1, the first elastic mechanism 2 is located above the second elastic mechanism 5, and the first elastic mechanism 2 and the second elastic mechanism 5 Divide the channel 10 into a first area 11 and a second area 12, the first area 11 is located above the first elastic mechanism 2, and is used to accommodate all flange nuts 3 to be assembled, and the second area 12 is located at the first elastic mechanism 2 and the second elastic mechanism 5. The push-pull mechanism 4 is set on the sleeve 1, and can move up and down along the length direction of the sleeve 1, a...

Embodiment 2

[0054] see image 3 As shown, the basic content of Embodiment 2 of the present application is the same as that of Embodiment 1. The difference is that the step assembly device of Embodiment 2 of the present application also includes a locking mechanism 7, and the locking mechanism 7 is assembled on the sleeve 1. And located in the second area 12 , and the locking mechanism 7 is used to limit the radial movement of the flange nut 3 located in the second area 12 . Since the flange nut 3 falling into the second area 12 is under the load of the second elastic mechanism 5, its axial movement (up and down in the figure) is restricted, but during the rotation, radial movement still occurs. Movement (the left and right directions in the figure) affects the tightening between the flange nut 3 and the bolt, so that the radial movement of the flange nut 3 is restricted by the locking mechanism 7, so that the flange nut 3 can rotate The center is always on the same axis as the bolt.

Embodiment 3

[0057] see Figure 4 with Figure 5 As shown, the basic content of embodiment 3 of the present application is the same as that of embodiment 1, except that the stepping assembly device of embodiment 3 of the present application also includes an unlocking mechanism 8, which is connected to the pawl 71 and used for the second Under the action of the elastic mechanism 5 , the ratchet 71 is pushed toward or away from the ratchet wheel 70 to engage with or separate from the ratchet wheel 70 . When the flange nut 3 in contact with the second elastic mechanism 5 rotates and moves downward, the second elastic mechanism 5 shrinks, and at this time the second elastic mechanism 5 pushes the unlocking mechanism 8 upward, and the unlocking mechanism 8 pushes the pawl 71 upward , so that the ratchet 71 is separated from the ratchet 70, the locking mechanism 7 rotates clockwise under the action of gravity, and the clamping structure 72 rotates from a horizontal state to a vertical state; wh...

Abstract

The invention relates to a hex flange nut stepping assembly device comprising a sleeve, a first elastic mechanism and a second elastic mechanism. A channel penetrating through the sleeve is formed inthe sleeve. The first elastic mechanism and the second elastic mechanism are arranged up and down in the length direction of the sleeve. The channel is divided into a first area and a second area through the first elastic mechanism and the second elastic mechanism. The first elastic mechanism is used for being ejected into the first area to bear all hex flange nuts held in the first area or for contracting to release a hex flange nut making contact with the first elastic mechanism. The second elastic mechanism is used for being ejected into the second area to bear a hex flange nut held in thesecond area or for contracting to release the hex flange nut. A push-pull mechanism is assembled on the sleeve, can move up and down in the length direction of the sleeve and is used for pushing the hex flange nut making contact with the first elastic mechanism into the second area, and thus the hex flange nut is in screw connection with a bolt. Continuous stepping assembly of all to-be-assembledhex flange nuts is achieved, and assembly efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of assembly equipment, in particular to a step-by-step assembly device for flange nuts. Background technique [0002] With the improvement of assembly automation in industrial production, it is especially required to simply, reliably and efficiently complete the fastening assembly of threaded nuts on industrial products with as little manual intervention as possible, so as to realize the fast connection between parts . [0003] At present, flange nuts (including hexagonal flange nuts, twelve-angle flange nuts, etc.) are widely used in the fields of aviation, ships, automobiles, etc. use. However, when the flange nuts and bolts are tightened, even if the nuts and bolts are assembled through automatic assembly, the nuts need to be tightened one by one, resulting in low production efficiency and high assembly man-hours. Contents of the invention [0004] The embodiment of the present application ...
