[0041] Referring to the accompanying drawings, this embodiment is described. A press-fitting tool for a motorcycle upper connecting plate bracket assembly part includes a supporting base plate 2, a rotating assembly, a first cylinder assembly, and a second cylinder assembly. The rotating assembly is rotatably connected to the supporting base plate 2. The rotating assembly includes a rotating base plate 3 and a rotating top plate 4.

The ratchet structure 26 is fixedly connected to the first boss structure 27. The upper end of the rotating base plate 3 is a second boss structure 28, and the lower end of the rotating base plate 3 is a disc structure 29. The second boss structure 28 is fixedly connected to the disc structure 29. The rotating base plate 3 and the rotating The boss structures of the top plate 4 are arranged relatively to each other, the rotating top plate 4 and the rotating bottom plate 3 are positioned by the locating pins 13 and fixed by bolts, the disc structure 29 is provided with a first through hole 22, and the ratchet structure 26 is provided with a second through hole 23 concentric with the first through hole 22, the first cylinder assembly includes a first cylinder 14 and a pressure head 9, the pressure head 9 is fixedly connected to the protruding end of the first cylinder 14, the second cylinder assembly includes a second cylinder 15, a rotating paddle 11 and a cylinder connector 12, the cylinder connector 12 is fixedly connected to the protruding end of the second cylinder 15, and the rotating paddle 11 is rotatably connected to the end of the cylinder connector 12 away from the second cylinder 15.

[0042] The bolts and locating pins 13 are used to improve the accuracy of the synchronous movement of the rotating components while ensuring the position accuracy of the corresponding holes, thereby ensuring the installation requirements of the semi-finished jacket and improving the press-fitting quality of the semi-finished jacket; through the cooperation of the first cylinder assembly and the second cylinder assembly, the press-fitting efficiency is greatly improved, while reducing the work intensity and learning cost of related personnel; through the utility model of the press-fitting tooling of the motorcycle upper connecting plate bracket assembly parts, the automation level of the equipment is greatly improved, which promotes the rationalization of production rhythm, regularization of production site operations, stabilization of production activities, realization of fixed-position management, improvement of on-site production efficiency, and improvement of enterprise production benefits.

[0043] The rotating assembly further includes a support shaft 7, a bearing 5, and a pressure cap 6. The first shoulder 16 of the support shaft 7 is connected to the supporting base plate 2. The inner surface of the bearing 5 is clamped to the second shoulder 17 of the support shaft 7. The outer surface of the bearing 5 is connected to the inner surfaces of the rotating top plate 4 and the rotating base plate 3. The pressure cap 6 is bolted to the support shaft 7. The support shaft 7 supports the bearing 5. The pressure cap 6 fixes the bearing 5 to reduce longitudinal displacement. The bearing 5 drives the synchronous rotation of the rotating assembly, ensuring the press-fit quality of the jacket 20 and the rubber sleeve 8.

[0044] The support base plate 2 is welded to the bracket 1. The bracket 1 supports the support base plate 2.

[0045] A first station 18 and a second station 19 are provided on the side of the bracket 1. The first cylinder 14 is fixed to the first station 18 via a first cylinder support frame 21, and the second cylinder 15 is fixed to the second station 19 via a second cylinder support frame 10. Specifically, the first station 18 is used to press-fit the jacket 20 and the rubber sleeve 8, and the second station 19 is used to rotate the rotating assembly. The first cylinder support frame 21 provides installation space for the first cylinder 14 to be installed in the first station 18, and the second cylinder support frame 10 provides space for the second cylinder 15 to be installed in the second station 19. Specifically, when the protruding end of the first cylinder 14 is extended, the jacket 20 and the rubber sleeve 8 are press-fitted by the pressure head 9, and when the protruding end of the second cylinder 15 is extended, the rotation of the rotating assembly is promoted by the rotating paddle 11.

[0046] When the extended end of the first cylinder 14 extends, the extended end of the second cylinder 15 retracts. When the extended end of the first cylinder 14 retracts, the extended end of the second cylinder 15 extends. Specifically, when the extended end of the first cylinder 14 is pressed downward, the extended end of the second cylinder 15 returns to its initial position. When the extended end of the second cylinder 15 extends to push the rotating assembly, the first cylinder 14 returns to its initial position. By alternately extending the extended ends of the first and second cylinders 14, 15, on-site production efficiency can be accelerated, improving the company's production benefits.

[0047] The rubber sleeve 8 is placed in the first through-hole 22, and the jacket 20 is placed in the second through-hole 23. The number of opposing first through-holes 22 and second through-holes 23 is no less than three. The semi-finished jacket is press-fitted by press-fitting the jacket 20 into the rubber sleeve 8, then placing the rubber sleeve 8 in the first through-hole 22 and the jacket 20 in the second through-hole 23. To ensure the proper placement of the jacket 20 and rubber sleeve 8, the press-fitting of the first cylinder 14, and the rotation of the rotating assembly driven by the second cylinder 15, the number of opposing first through-holes 22 and second through-holes 23 is no less than three.

[0048] The rotating base plate 3 has a tapered stopper hole formed near each second through hole 23. The supporting base plate 2 has a spring stopper hole 25, within which a stopper spring and a stopper ball are placed. The tapered stopper hole, stopper spring, and stopper ball coordinate with each other to position the first through hole 22 relative to the first cylinder 14, while also buffering the thrust of the second cylinder 15, ensuring the operational accuracy of the first cylinder 14 and the quality of the press-fitting of the jacket 20 and rubber sleeve 8.

[0049] The limiting ball is connected to the top of the limiting spring. When the conical limiting hole is aligned with the spring limiting hole 25, the limiting ball protrudes above the plane of the support base 2. The limiting spring allows the limiting ball to have room for expansion and contraction. When positioned, the limiting ball protrudes above the plane of the support plate. When the rotating assembly rotates, the limiting ball is subjected to pressure from the rotating base 3, compressing the limiting spring, thereby causing the limiting ball to be lower than the plane of the support base 2.

[0050] The cylinder connecting head 12 is provided with a hard structure 30 at a position on the side of the rotating paddle 11 close to the second station 19. When the rotating paddle 11 pushes the rotating assembly, the hard structure 30 prevents the rotating paddle 11 from rotating in the direction opposite to the direction of movement. The cylinder connecting head 12 is provided with a hard structural part 30 at a position where the rotary paddle 11 is close to the side of the second workstation 19. When the protruding end of the second cylinder 15 is extended, the hard structural part 30 blocks the rotary paddle 11 in the direction opposite to the movement direction, so that the rotary paddle 11 pushes the rotating assembly. When the protruding end of the second cylinder 15 is retracted, the rotary paddle 11 rotates along the cylinder connecting head 12 under the obstruction of the ratchet structure 26 and contacts the upper surface of the ratchet structure 26 until the protruding end of the second cylinder 15 is fully retracted, and the rotary paddle 11 slides over the upper surface of a gear tooth of the ratchet structure 26 to the initial position. The provision of the hard structural part 30 can prevent the rotary paddle from slipping when pushing the rotating assembly to rotate. The connection method based on the rotary paddle rotation connection to the cylinder connecting head can prevent the rotary paddle from getting stuck on the ratchet teeth when the protruding end of the second cylinder is retracted, thereby improving the reliability and stability of the tooling process.

[0051] The cross-section of the support base plate 2 is not less than 1 / 2 of a circle. The upper surface of the support base plate 2 supports the rubber sleeve 8. After being pressed, the jacket 20 and the rubber sleeve 8 are rotated to a position outside the support base plate 2 by the second cylinder 15, and then fall to a predetermined position.

[0052] The specific working process of the press-fitting tool for the upper connecting plate bracket assembly parts of a motorcycle in the present application is as follows:

[0053] The jacket 20 is placed in the second through hole 23, and the rubber sleeve 8 is placed in the first through hole 22. The bottom end of the jacket 20 contacts the top end of the rubber sleeve 8 to realize the pre-assembly of the jacket 20 and the rubber sleeve 8. The protruding end of the second cylinder 15 is operated to extend and push the rotating assembly to rotate the pre-assembled jacket 20 and rubber sleeve 8 to the first workstation 18. The protruding end of the first cylinder 14 is operated to extend and the pre-assembled jacket 20 and rubber sleeve 8 are press-fitted by the pressing head 9. At the same time, the protruding end of the second cylinder is retracted, so that the rotating paddle slides over the surface of the ratchet teeth, and the rotating paddle returns to the teeth of the ratchet structure 26 of the rotating top plate to be pushed. After the press-fitting is completed, the protruding end of the first cylinder 14 is retracted and the protruding end of the second cylinder 15 is extended. Under the obstruction of the hard structure 30, the teeth of the ratchet structure 26 of the rotating top plate are pushed, thereby pushing the rotating assembly to rotate. The press-fitted jacket 20 and rubber sleeve 8 rotate with the rotating assembly and finally fall to the specified position.

[0054] Obviously, the embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor do they limit the present invention to the specific implementation methods described. According to the contents of this specification, many modifications and changes can be made.
