At the same time, the arc bar 84 moves to change the position of the buttress 89 inside the butt groove 88, and uses the displacement difference to make the slide 87 push a group of buttresses 7 to abut the end of the handlebar tube.

[0052] Embodiment 4: Based on Embodiment 3, refer to the attached Figure 1 , Attachment Figure 5 ;

[0053] A feeding unit 85 is arranged outside the arc bar 84, and the feeding unit 85 includes a trough 851, which is in an inverted T-shape and is opened on the body of a group of stoppers 7 and is in a through-state. One side of the inside of the trough 851 is coaxial with the arc groove 6, and the inner diameters of the two are the same, so that after a group of stoppers 7 contacts the end of the handlebar tube, the trough 851 is directly connected to the inside of the handlebar tube. At the same time, the cross-sectional size of one side above the trough 851 is adapted to the axial cross-sectional size of the counterweight block. The inside of the trough 851 is slidably connected with a slide cylinder 853, and the slide cylinder 853 can push the counterweight block into the trough 851 through reciprocating motion. Inside one end of the handlebar tube, the slide 853 is rotatably connected to a roller 854, and the outer surface of the roller 854 is fixedly connected to a pusher motor 855.

[0054] In this embodiment, when the counterweight block falls from the upper side of the material trough 851 to the lower side, the pushing motor 855 drives the roller 854 to rotate forward and reverse, and through the spiral abutment between the spiral groove 856 and the rotary block 857, it pushes the slide 853 to reciprocate horizontally at the bottom of the material trough 851, so that the counterweight block can be pushed into the interior of one end of the handlebar tube.

[0055] Embodiment 5: Based on Embodiment 4, refer to the attached Figure 5 , Attachment Figure 6 ;

[0056] A feeding module 852 is arranged outside the material trough 851, and the feeding module 852 includes a material pipe 8521. A vibration plate is arranged outside the initial position of the material pipe 8521 to uniformly and neatly add the counterweight block to the material pipe 8521 for storage. The interior of the material pipe 8521 is connected to the interior of the material trough 851. The outer surface of the material pipe 8521 is fixedly connected to the outer surface of a group of seats 7. Two baffles 8522 are slidably connected to the interior of the material pipe 8521. One side of the surface of the baffle 8522 can be chamfered so that In order to better contact with the counterweight block, the stacked counterweight blocks can be separated one by one. The outer surfaces of the two baffles 8522 are fixedly connected with racks 8523. The outer surfaces of the two racks 8523 are meshed with gears 8524. The body of the gear 8524 is fixedly connected with a rotating rod 8525. The outer surface of the rotating rod 8525 is sleeved with a torsion spring 8526. The torsion spring 8526 can make the baffle 8522 move in the reverse direction and reset by rebounding. The outside of the material tube 8521 is fixedly connected with a fixed frame 8527. The fixed frame 8527 The body is provided with a cable through hole, and the inner side of the through hole end is provided with an arc chamfer to avoid scratching the cable. The outer surface of the baffle 8522 is movably connected to the outer surface of the fixed frame 8527. The end of the rotating rod 8525 is embedded and rotatably connected to the outer surface of the fixed frame 8527. The two ends of the torsion spring 8526 are respectively fixedly connected to the gear 8524 and the outer surface of the fixed frame 8527. The outer surface of the fixed frame 8527 is fixedly connected with a winding motor 8528. The winding motor 8528 is made of a servo motor and is connected to an external control. The control circuit is electrically connected, and the output end of the winding motor 8528 is fixedly connected to the reel 8529. The reel 8529 pulls the rack 8523 to move by winding the cable, which can reduce the space occupied and the size of the equipment. On the one hand, it can avoid movement interference with other structures, and on the other hand, it can reduce the influence of inertia on the stability of a group of seats 7. The outer surface of the reel 8529 is wrapped with a cable, one end of the cable is slidably connected to the body of the fixed frame 8527, and one end of the cable is fixedly connected to the outer surface of the rack 8523 on one side.

[0057] In this embodiment, the vibration plate neatly adds the counterweights into the feed tube 8521 for storage. When riveting is required, the winding motor 8528 first drives the reel 8529 to rotate to wind the cable, thereby pulling the upper rack 8523 and the baffle 8522 to move, so that the upper baffle 8522 is out of contact with the counterweight. When the upper rack 8523 moves, it meshes with the gear 8524, so that the gear 8524 drives the rotating rod 8525 to rotate and compresses the torsion spring 8526, thereby The meshing of 8523 and gear 8524 causes the lower baffle 8522 to synchronously move in the opposite direction and enter the material tube 8521 to receive the counterweight block. Then the winding motor 8528 reverses and releases the stretching, and the upper baffle 8522 enters the material tube 8521 and contacts the counterweight block adjacent to the lowest counterweight block, abutting against it, and the lower baffle 8522 resets to disengage from the abutment against the lowest counterweight block, so that the lowest counterweight block is separated and falls into the material trough 851. Repeating the above steps can separate the counterweight blocks one by one.

[0058] The present invention also discloses a riveting process for a handlebar counterweight, which specifically comprises the following steps:

[0059] Step 1: Use a manipulator to place the handlebar tube to be riveted on the upper groove plate 12, then the push plate 2 abuts against the fixed seat 5 to support it, and then the screw tube 83 moves through the arc bar 84 and the connecting plate 86 to drive the two sets of abutment seats 7 to center and limit the handlebar tube;

[0060] Step 2: The vibration plate adds the counterweight blocks into the material tube 8521. The baffles 8522 on both sides move respectively to add the counterweight blocks into the material trough 851 one by one. The slide cylinder 853 pushes the counterweight blocks into the handlebar tube. Then the extrusion rod 11 drives the punch 9 to move and perform riveting on the handlebar tube.

[0061] Step three, the flip motor 35 drives the key shaft 31 and the rubber sleeve 32 to rotate, and the handlebar tube is rotated by the contact friction between the rubber sleeve 32 and the handlebar tube, and then the handlebar tube is subjected to equal-angle riveting treatment by the punch 9. After the riveting is completed, when the push plate 2 and the stop seat 7 move to reset, the handlebar tube is abutted by the stop seat 7 on the other side, and the material is discharged through the lower groove plate 12.

[0062] Finally, the final product is obtained through the above process. Figure 7-8 As shown, the handlebar tube surface is not punched and welded, but is directly formed by riveting with special equipment, which is more efficient. The punching process and welding process are omitted, and the original three processes are simplified to one riveting process, saving time and labor. Previously, three people were required to complete the three processes, and only about 2,200 pieces were made a day. Now one device can make 2,500 pieces a day.
