[0021] Please refer to Figure 1 , this embodiment provides an installation machine for wheel spoke steel wires, including a chassis 5, a feeding mechanism 1, a rotary positioning mechanism 2 and a material clamping mechanism 3. The top of the chassis 5 is a workbench 4, a rotary positioning mechanism is provided at the center of the workbench, a feeding mechanism is provided on the workbench on one side of the rotary positioning mechanism, and a material clamping mechanism is provided on the workbench on the other side of the rotary positioning mechanism.

[0022] The described feeding mechanism includes a base 191, on which a material placing groove 18 is provided. The material placing groove includes two vertical side plates on the left and right and two front and rear baffles. The front baffle 19 is arranged obliquely from the front side slot towards the center of the slot bottom. The rear baffle 12 is arranged obliquely from the rear side slot towards the center of the slot bottom and extends past the lower end of the front baffle. The lower end of the front baffle does not directly contact the rear baffle, and there is a strip-shaped through groove left between the two baffles. A rectangular pushing plate 11 passes through the strip-shaped through groove and is placed on the rear baffle, and can slide up and down along the rear baffle under the push of a power device inside the base. The thickness of the pushing plate is equal to or slightly larger than the diameter of the spoke wire. A conveying rail 17 is horizontally arranged along the left and right ends of the material placing groove behind the material placing groove. The conveying rail is formed by fixing the two ends of two parallel strip-shaped plates, so that a conveying through groove 14 is formed between the two strip-shaped plates. The width of the conveying through groove is slightly larger than the diameter of the spoke wire and smaller than the diameter of the wire cap of the spoke wire. The upper end of the conveying rail is slightly lower than the slot opening of the material placing groove. One end of the conveying rail extends out of the material placing groove for a section towards the rotation positioning mechanism. A horizontal pushing device is arranged behind the conveying rail. The horizontal pushing device includes a guide rail 13 and a pushing cylinder 15. A push rod 192 extending to the lower part of the conveying rail is arranged on the pushing cylinder.

[0023] Above the conveying through groove where the conveying rail extends out of the left end of the material placing groove, a limiting strip 16 is horizontally arranged along the conveying rail. One side of the middle part of the limiting strip is fixed on the conveying rail through a vertical rod.

[0024] The described rotation positioning mechanism includes a stepping rotation device and a positioning device. The stepping rotation device includes a rotating shaft seat 21 fixed at the center of the workbench. A rotating shaft 22 is movably connected inside the rotating shaft seat. A central shaft 24 is arranged at the center of the rotating shaft. The rotating shaft can be driven by a stepping motor under the workbench to step-rotate around the central shaft. A spring pin 23 is arranged on one side of the top of the rotating shaft. After the center of the hub 29 passes through the central shaft of the stepping rotation device, it is placed on the top of the rotating shaft, and the spring pin at the top of the rotating shaft is inserted into the wire hole at the lower end of the hub, and the hub is driven by the rotating shaft. A positioning device is arranged on the workbench behind the stepping rotation device. The positioning device includes a fixing frame one 26 fixed on the workbench. A positioning clamp cylinder 27 is arranged on the fixing frame one. A positioning clamp 28 is arranged on the positioning clamp cylinder. A vertical semi-circular channel is arranged opposite to the two clamping claws of the positioning clamp. The circular channel formed by the two semi-circular channels has its lower port opposite to the wire hole of the hub, and the upper port of the circular channel is a funnel-shaped guiding hole 25.

[0025] A guiding device is arranged on the left side of the stepping rotation device. The guiding device includes an arc-shaped guiding piece 292 arranged on one side of the central shaft. The arc-shaped guiding piece is arranged with its lower end slightly inclined outwards towards the hub. The arc-shaped guiding piece is fixed on the workbench through a support rod 291.

[0026] The described material clamping mechanism includes a second fixed frame 35. A horizontal lateral pushing device 34 is provided on the second fixed frame. A longitudinal pushing device 33 is provided on the horizontal lateral pushing device. A material taking clamp cylinder 32 is provided on the longitudinal pushing device. A material taking clamp 31 is provided on the material taking clamp cylinder.

[0027] A pressing plate 36 is provided on one side of the material taking clamp.

[0028] When the automatic spoke wire installation machine of the present invention works, first place the spoke wire into the feeding groove of the feeding mechanism. The pushing plate in the feeding groove pushes upward from the bottom of the feeding groove along the rear baffle. Since the thickness of the pushing plate is equal to or slightly larger than the diameter of the spoke wire, the pushing plate will only push one wire at a time, and the excess wires will roll back into the feeding groove from the top of the pushing plate. When the pushing plate pushes the spoke wire past the notch of the feeding groove, the spoke wire will roll into the conveying through groove of the conveying rail. The wire cap at the bent end of the spoke wire will be stuck above the conveying through groove, and the rest will pass through the conveying through groove and be placed below the conveying rail, so that the spoke wire is vertically hung on the conveying rail. Then start the pushing cylinder of the pushing device, so that the push rod on the pushing cylinder abuts against the spoke wire and slides along the conveying rail to the left end of the conveying rail. The limiting strip above the left end of the conveying rail plays a role in pressing the spoke wire to prevent the spoke wire from swinging under the push of the pushing cylinder.

[0029] After the spoke wire is pushed to the left end of the conveying rail, start the horizontal pushing device of the material clamping device, push the material taking clamp to the position of the spoke wire, clamp the spoke wire and then move back to above the positioning clamp of the rotation limiting device. Then, through the vertical pushing device, move the spoke wire downward and insert it into the circular channel formed by the two clamping claws of the positioning clamp. Since a funnel-shaped guiding hole is provided above the circular channel of the positioning clamp, the spoke wire can be smoothly inserted into the circular channel. After the spoke wire passes through the circular channel, it is inserted into the wire hole of the upper wheel disc of the hub. After the spoke wire passes through the wire hole of the upper wheel disc of the hub, it will touch the arc-shaped guiding piece on one side of the middle part of the hub and move downward along the outside of the arc-shaped guiding piece. In this way, it can prevent the lower end of the spoke wire from abutting against the lower wheel disc of the hub and ensure that the spoke wire is inserted in place. After one spoke is inserted, the material taking clamp and the positioning clamp will be opened at the same time, and the opening angle of the positioning clamp is 180 degrees, so that the stepping rotation device can drive the hub to step-rotate, making the next wire hole of the hub opposite to the circular channel of the positioning clamp to complete the insertion of the next spoke wire.

[0030] The pressing plate on one side of the material taking clamp cylinder can further press the spoke wires that are not inserted in place while the material taking clamp moves downward to insert the spoke wire.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
