[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] Please see Figure 1-4 This utility model provides a technical solution: a nut assembly device for a bicycle bell, comprising: Base 1; Vibratory feeder 2 is fixedly installed on base 1, and a discharge track 21 is provided at the discharge port of vibratory feeder 2; The support frame 3 has a notch, and the support frame 3 has an end block 31 with a position corresponding to the notch. A first side block 32 and a second side block 33 are arranged in parallel on one side of the notch. The bottom of the discharge track 21 is placed on the support frame 3, and the bottom end of the discharge track 21 extends to one side of the first side block 32. The gap between the first side block 32 and the second side block 33 forms a nut conveying channel. The pusher cylinder 4 is fixedly mounted on the support frame 3; The pusher 5 is fixedly installed on the fixed plate of the pusher cylinder 4. The pusher 5 is provided with a push rod 51, which extends into the nut conveying channel. The contour positioning block 6 is fixedly installed on the base 1. The position of the contour positioning block 6 corresponds to the notch. The contour positioning block 6 is provided with a positioning groove 61 whose shape matches the cross section of the bell 9.

[0023] When the clamping ring of the bell 9 needs to be assembled with the nut 91, the cylinder is used to push the nut 91 to assemble with the clamping ring of the bell 9. The operator only needs to manually place the bell 9 in the fixed assembly position formed by the contour positioning block 6 and the support frame 3. The assembly quality is stable and the assembly efficiency is high, which solves the problem that the nut on the clamping ring of the bicycle bell is easy to be misassembled and the assembly efficiency is low.

[0024] The end stop 31 is provided with a waist-shaped hole 311, which makes the position of the end stop 31 adjustable, effectively ensuring that the position of the opening groove on the side wall of the clamping ring corresponds to the nut conveying channel.

[0025] The contour positioning block 6 has symmetrically arranged second side wall grooves 62 on both sides, and the base 1 has an mounting plate 11. The mounting plate 11 has an "L" shaped cross section and is fixedly installed on the side wall of the contour positioning block 6. Specifically, the two can be fixed by adhesive or screws.

[0026] The contour positioning block 6 is made of plastic to prevent damage to the bell 9 during the assembly of the nut. The contour positioning block 6 is placed on the base 1 and fixed by the mounting plate 11. The end of the mounting plate 11 is inserted into the second side wall groove 62 of the contour positioning block 6 to effectively prevent the contour positioning block 6 from detaching from the surface of the base 1.

[0027] Working principle: When the clamping ring of bell 9 needs to be assembled with nut 91, bell 9 is slid horizontally into the positioning groove 61 on the contour positioning block 6 with the clamping ring facing upwards. At this time, the clamping ring of bell 9 extends into the notch on the support frame 3 and is held in place by the end stop 31. The position of the opening groove on the side wall of the clamping ring corresponds to the nut conveying channel. Driven by the pushing cylinder 4, the pushing rod 51 of the pushing component 5 pushes the nut 91 along the nut conveying channel into the opening groove on the side wall of the clamping ring, completing the nut assembly. After assembly, the pushing rod 51 retracts and no longer blocks the end of the discharge track 21, allowing the nut 91 stored in the vibratory plate 2 to be conveyed back into the nut conveying channel through the discharge track 21. At the same time, a new bell 9 is manually replaced on the contour positioning block 6 for the next assembly. Example 2

[0028] This embodiment further improves upon the above embodiment by providing the following technical solution: A detachable pressure plate 7 is provided on the first side stop 32. The pressure plate 7 can be fixed by bolts, and its end extends to the upper front side of the end of the discharge track 21. After the nut 91 is output from the discharge track 21 and enters the nut conveying channel, it is restricted above by the pressure plate 7 to prevent the nut's posture from changing, making it easier for the nut to be pushed into the clamping ring of the bell 9.

[0029] Preferably, the pressure plate 7 has a first opening 71 at its end. The first opening 71 allows the nut below the pressure plate 7 to be observed, thus determining whether a nut is present. Example 3

[0030] This embodiment further improves upon the above embodiment by providing the following technical solution: an arc-shaped bent edge 72 is provided at the end of the pressure plate 7. The arc-shaped bent edge 72 is bent upwards to avoid collision damage with the push rod 51. Example 4

[0031] Based on the above embodiments, this embodiment further improves upon the following technical solution: the end stop 31 is provided with a "V"-shaped second opening 312, so that the end stop 31 has a guiding effect when positioning, effectively positioning the clamping ring of the bell 9. Example 5

[0032] Based on the above embodiments, this embodiment further improves upon the following technical solution: a first side wall groove is provided on the second side block 33, and the push rod 51 extends into the first side wall groove, the thickness of the push rod 51 being less than the thickness of the nut 91.

[0033] The shape of the first sidewall groove matches the push rod 51, which restricts the smooth sliding of the push rod 51 and does not affect the conveying of the nut 91.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
