[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0025] One embodiment of the present application, such as Figures 3 to 5 As shown, a clamping and fixing device for a motorcycle rocker arm comprises a base plate 11, a positioning assembly and a bracket 12; the positioning assembly comprises a first clamping assembly arranged at the left end of the base plate 11 and a second clamping assembly arranged at the right end of the base plate 11; the first clamping assembly comprises a left end stop post 13, a left end positioning post 14, a left end downward pressure baffle 16, a left end side limit post 19 and a left end bearing seat 24; the left end stop post 13, the left end positioning post 14 and the left end side limit post 19 are all uprightly arranged above the base plate 11; a vertical limit groove is provided between the left end stop post 13 and the left end positioning post 14, and a horizontal limit groove is provided between the left end side limit post 19 and the left end positioning post 14; the left end downward pressure baffle 16 covers the top of the vertical limit groove, and when the left end downward pressure baffle 16 is fixed to the left end positioning post 14, the left end downward pressure baffle 16 will The top of the frame mounting tube is pressed; the second clamping assembly includes a right end bearing seat, a right end side limit column 20 and a right end side positioning column 21 arranged opposite to the right end side limit column 20; the top of the right end side positioning column 21 is provided with a right end downward pressure baffle; the right end side limit column 20 and the right end side positioning column 21 are both uprightly arranged above the bottom plate 11; a transition limit groove is provided between the right end side limit column 20 and the right end side positioning column 21, and the right end downward pressure baffle 22 covers the top of the transition limit groove, and when the right end downward pressure baffle 22 is fixed to the right end side positioning column 21, the right end downward pressure baffle 22 presses the right end of the rocker arm body of the motorcycle rocker arm; the left end bearing seat 24 and the right end bearing seat are mounted on the bottom plate 11 and correspond to the positioning holes on the motorcycle rocker arm; both ends of the bottom plate 11 are connected to the bracket 12.

[0026] The left-end downward pressure baffle comprises a vertical strip plate and a transverse sliding plate. A transverse slide rail 15 is provided on the top of the left-end positioning column 14, and the transverse sliding plate is slidably mounted on the transverse slide rail 15. A locking bolt 17 is provided between the transverse sliding plate and the left-end positioning column 14. The locking bolt 17 is used to position the transverse sliding plate relative to the left-end positioning column 14. This allows the left-end downward pressure baffle to slide or position relative to the left-end positioning column 14, facilitating precise installation and removal of the motorcycle swing arm.

[0027] First vertical bolts 18 are installed at both ends of the vertical strip, corresponding to positioning holes on the motorcycle's swingarm. Using these first vertical bolts 18 for precise point-to-hole positioning is more secure and accurate than surface-to-surface or point-to-surface positioning. Furthermore, by turning these first vertical bolts 18, the clamping tightness can be adjusted.

[0028] A linear slide rail is provided on the top of the right side locating post, on which the right side pressure baffle 22 is slidably mounted. A locking bolt 17 is provided between the right side pressure baffle 22 and the right side locating post.

Driven by the tilting drive device 27, the base plate 11 can rotate the motorcycle rocker arm, making the motorcycle rocker arm processing operation more flexible and convenient.

[0033] During the actual clamping operation of the motorcycle swing arm, the locking bolt of the left-end downward pressure baffle is first loosened, and the left-end downward pressure baffle is slid away from the vertical limit groove so that the top of the vertical limit groove is completely exposed. Similarly, the locking bolt of the right-end downward pressure baffle is loosened, and the right-end downward pressure baffle is slid away from the transition limit groove so that the top of the vertical limit groove is completely exposed. The first and second vertical bolts are then adjusted upward to a suitable position. The motorcycle swing arm is placed into the positioning assembly, specifically, the frame mounting tube portion of the motorcycle swing arm is placed into the vertical limit groove, and the horizontal structure of one side of the right end of the motorcycle swing arm is placed into the horizontal limit groove. The right end of the swing arm body of the motorcycle swing arm is placed where it connects to the eccentric chain adjuster mounting hole into the transition limit groove. Slide the left-end downward pressure baffle to cover the top of the vertical limit groove, adjust the locking bolt and the first vertical bolt, so that the left-end downward pressure baffle presses the right end of the motorcycle rocker arm downward, the first vertical bolt presses into the positioning hole at the corresponding position, and the receiving seat at the right end of the base plate presses upward into the positioning hole at the right end of the motorcycle rocker arm, lifting the right end of the motorcycle rocker arm in the air. Slide the right-end downward pressure baffle to cover the top of the transition limit groove, adjust the locking bolt and the second vertical bolt, so that the right-end downward pressure baffle presses the left end of the motorcycle rocker arm downward, the second vertical bolt presses into the positioning hole at the corresponding position, and the receiving seat at the left end of the base plate presses upward into the positioning hole at the left end of the motorcycle rocker arm, lifting the left end of the motorcycle rocker arm in the air.
