Technical Field

[0001] The utility model relates to the technical field of punching, in particular to a punching device for small holes on the side of a motorcycle starting rod. Background Technique

[0002] A motorcycle starting rod, also known as a starting lever or a foot lever, is a traditional starting device on a motorcycle. By means of the force of stepping on and leveraging the principle of leverage, the engine crankshaft is rotated to start the motorcycle. There are mainly two common starting rod structures for motorcycles: the two-rod type and the integral type.

[0003] When a motorcycle starting rod is produced, it usually needs to be punched. However, due to the relatively curved structure and smooth material of the motorcycle starting rod, it is usually difficult to effectively fix it, resulting in the starting rod shaking back and forth during punching, thus reducing the punching quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] AsFigures 1-4 As shown in the figure, a punching device for small holes on the side of a motorcycle starting lever proposed by the present utility model is used in cooperation with the starting lever 5. There is a bent portion on the starting lever 5, and a side connecting block 501 is provided at one end. The punching device for small holes on the side of the motorcycle starting lever includes a bottom plate 1, a fixing component 3, and a punching component 4. The fixing component 3 is arranged on the bottom plate 1, and by making two socket plates 35 approach each other and clamping and covering the bent portion on the starting lever 5 therein, the starting lever 5 is limited. The punching component 4 is arranged on the bottom plate 1, and the side connecting block 501 is punched by the rotation of the drill bit 44.

[0023] Furthermore, two groups of fixing components 3 are provided on the bottom plate 1, so that the limitation of the starting lever 5 can be more firm.

[0024] Furthermore, the fixing component 3 includes fixing plates 31 symmetrically arranged on the bottom plate 1; a bidirectional lead screw 32 is rotatably connected between the two fixing plates 31; one end of the bidirectional lead screw 32 is connected to the driving end of a driving mechanism one 33 arranged on the fixing plate 31, and sliding plates 34 are symmetrically threadedly connected thereto; the driving mechanism one 33 is a motor; both sliding plates 34 are slidably connected in a chute opened at the upper end of the bottom plate 1, and socket plates 35 are connected to the upper ends of both sliding plates 34. When the two socket plates 35 move relatively to abut against each other, they exactly match and fit with the bent portion on the starting lever 5. The two socket plates 35 can clamp the bent portion of the starting lever 5 from both sides, thereby fixing the starting lever 5, preventing the starting lever 5 from shaking during punching, thus causing defects in the punched holes and reducing the production quality of the starting lever 5.

[0025] Furthermore, a plurality of convex balls 36 are evenly provided on the opposite sides of the two socket plates 35. The friction between the socket plates 35 and the starting lever 5 can be increased, further preventing the starting lever 5 from shaking during punching.

[0026] Furthermore, an insertion block 37 is provided on one of the socket plates 35, and a slot 38 for mating and clamping with the insertion block 37 is opened on the other socket plate 35. The two socket plates 35 are perfectly docked, preventing the two socket plates 35 from not being docked in place, resulting in a gap between the socket plates 35 and the starting lever 5.

[0027] Furthermore, the punching component 4 includes a fixing frame 41 arranged on the bottom plate 1; a driving mechanism two 42 is provided at the top of the fixing frame 41; the driving mechanism two 42 is a motor; the driving end of the driving mechanism two 42 is connected to an electric telescopic rod 43; the telescopic end of the electric telescopic rod 43 is connected to a drill bit 44 for punching the side connecting block 501. The side connecting block 501 can be punched.

[0028] Further explanation: A collection cylinder 45 is provided below the drill bit 44; a suction fan 46 is provided inside the collection cylinder 45; a filter plate 47 connected to the inner wall of the collection cylinder 45 is provided above the suction fan 46. This can collect the debris generated during drilling to avoid the debris flying around and increasing the cleaning burden.

[0029] Further explanation: A bracket 2 for placing the starting rod 5 is also provided at the upper end of the bottom plate 1, which can support the starting rod 5.

[0030] The working principle of the present utility model is as follows: During operation, first place the starting rod 5 on the bracket 2, then start the driving mechanism one 33 to drive the bidirectional lead screw 32 to rotate, so that the two sliding plates 34 drive the socket plate 35 to slide relative to each other along the chute, thereby enabling the two socket plates 35 to clamp the bent portion of the starting rod 5 from both sides, and further fixing the starting rod 5 to prevent the starting rod 5 from shaking during drilling. Then start the driving mechanism two 42 to drive the drill bit 44 to rotate, and start the electric telescopic rod 43 to drive the drill bit 44 to extend and retract to drill the side connection block 501. At the same time, start the fan 46 to adsorb the debris generated during drilling onto the filter plate 47 to collect the debris.

[0031] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited thereto. Various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the art to which it pertains.
