[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] likeFigures 1 - 4 As shown in the figure, a fixture for assembling and fixing an axle proposed by the present utility model includes an axle body 1, a main support block 2, and a secondary support block 10. A locking assembly is provided on the main support block 2, and the axle body 1 is positioned on the main support block 2 through the locking assembly. A bearing plate 11 is provided on the secondary support block 10 and is lifted and lowered through a lead screw assembly. The bearing plate 11 abuts against the lower surface of the end of the axle body 1. There are two bearing plates 11 in total, and the two bearing plates 11 are symmetrically distributed with respect to the axle body 1.

[0022] Based on Embodiment 1:

[0023] During the use of the fixture for assembling and fixing the axle of the present utility model, the fixture for assembling and fixing the axle is fixed on the assembly line by bolts for the main support block 2 and the secondary support block 10. During use, the product axle body 1 is hoisted and placed on the V-shaped block 7 of the main support. Adjust the stroke and buckle of the locking assembly to achieve the clamping action of the product. When the product needs to be rotated by a certain angle for installation, use the auxiliary support for adjustment. Rotate the auxiliary support lead screw to adjust the position of the bearing plate 11 up and down, so as to facilitate the adjustment of the angle of the axle body 1 and meet the assembly requirements; when the assembly is completed, loosen the lead screw assembly of the auxiliary support and loosen the locking assembly, and then hoist and remove the product.

[0024] Embodiment Two

[0025] As Figures 1 - 4 shown in the figure, a fixture for assembling and fixing an axle proposed by the present utility model. Compared with Embodiment 1, this embodiment further includes: bottom plates 9 are provided on the lower surfaces of the main support block 2 and the secondary support block 10, and round holes are opened at the four corner positions of the bottom plates 9. The fixture for assembling and fixing the axle is fixed on the assembly line by bolts for the main support block 2 and the secondary support block 10.

[0026] The locking assembly is composed of a locking arm 3, a positioning arm 4, a pressing block 5, a rotating arm 6, a V-shaped block 7, a screw rod 8, and a lock 14. Two V-shaped blocks 7 are fixed at the top of the main support block 2, and the axle body 1 is placed on the two V-shaped blocks 7.

[0027] The locking arm 3 is provided on one side of the lower end of the main support block 2, the lock 14 is rotatably provided on the locking arm 3, the positioning arm 4 is provided on the other side of the lower end of the main support block 2, one end of the rotating arm 6 is rotatably provided at the top of the positioning arm 4, and the other end of the rotating arm 6 is buckled with the said lock 14. At this time, control the rotating arm 6 to rotate along the positioning arm 4. After the rotating arm 6 is above the axle, fix the movable end of the rotating arm 6 on the locking arm 3 through the lock 14.

[0028] The screw 8 is threadedly installed at the middle position of the rotating arm 6. The pressing block 5 is rotatably installed at the bottom end of the screw 8. The pressing block 5 abuts against the upper surface position of the axle body 1. Then, by rotating the screw 8, through the threaded engagement action between the screw 8 and the rotating arm 6, the pressing block 5 moves downward to abut against the surface of the axle, and thus the position of the axle can be positioned.

[0029] The lead screw assembly is composed of a rotating block 12 and a lifting rod 13. The bottom end of the lifting rod 13 is slidably inserted into the secondary support block 10, and the lifting rod 13 is limited by the secondary support block 10 and does not rotate. The rotating block 12 is rotatably installed on the upper surface of the secondary support block 10. The rotating block 12 and the lifting rod 13 are in a threaded engagement state. The bearing plate 11 is fixed at the upper end position of the lifting rod 13. Further, due to the design that the lifting rod 13 can only slide up and down and cannot rotate, in cooperation with the threaded engagement action between the rotating block 12 and the lifting rod 13, under the principle of the lead screw, by rotating the rotating block 12, the lifting rod 13 can be controlled to perform lifting actions. When the axle rotates and adjusts the angle, it is ensured that the bearing plate 11 performs a following lifting action, so that the bearing plate 11 always contacts the surface of the axle to provide support for it.
