Description

Technical Field

[0001] This utility model relates to the technical field of motorcycle parts production equipment, and in particular to a painting device for producing motorcycle rocker arms. Background Technology

[0002] The rocker arm is a crucial component of the motorcycle's rear suspension system. Its primary function is to connect the rear wheel to the frame, achieving an elastic connection between the two. To enable the rocker arm to rotate between the frame and the rear wheel, pivot holes are provided on the front and rear ends of the rocker arm. After the rocker arm is welded or integrally formed, it is painted to enhance its durability. In existing technology, when painting the rocker arm, the pivot holes need to be manually plugged with plugs to prevent paint from entering during the painting process. After painting, the plugs are manually removed. This manual insertion and removal of plugs during the painting process makes the rocker arm painting process cumbersome and inefficient.

[0003] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0020] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] As shown in the figure, a painting device for producing motorcycle rocker arms includes a frame 1. The frame 1 is equipped with a clamping mechanism 2 and a painting mechanism 3. The clamping mechanism 2 includes sliding seats 21, support plates 22, positioning clamping rods 23, and telescopic clamping rods 24. Two sliding seats 21 are slidably mounted on the side plates of the frame 1 and are connected to a drive source mounted on the frame 1. Two support plates 22 are rotatably mounted on the two sliding seats 21 via rotating shafts 25. The front ends of the two support plates 22 are respectively connected to positioning clamping rods 23 and telescopic clamping rods 24 with opposite ends, and the rear ends are respectively connected to two telescopic clamping rods 24 with opposite ends. The telescopic clamping rod 24 includes a fixed tube 241 fixedly connected to the support plate 22 and a telescopic rod 242 slidably passing through the fixed tube 241. A clamping spring 243 is provided in the fixed tube 241 and abuts against the telescopic rod 242. Rubber plugs 26 are connected to the ends of the positioning clamping rod 23 and the telescopic rod 242. A gear 27 is fixedly connected to the rotating shaft 25. A rack 12 that meshes with the transmission gear 27 along the direction of the sliding seat 21 is provided on the frame 1. The painting mechanism 3 includes a painting chamber 31 provided on the frame 1 and a plurality of spray nozzles 32 provided in the painting chamber 31 above the moving path of the clamping mechanism 2.

[0022] Specifically, the structure in which the sliding seat 21 is slidably mounted on the frame 1 and connected to the drive source is as follows: each of the two side plates of the frame 1 is provided with a linear slide rail 11, and the two sliding seats 21 are respectively mounted on the two linear slide rails 11. The drive source is a motor 14, and each of the two side plates of the frame 1 is provided with a synchronous belt 13 that is connected to the motor 14. The two sliding seats 21 are respectively fixedly connected to the two synchronous belts 13.

[0023] In the above structure, when connecting the spray nozzle 32 to an external paint supply device for painting a motorcycle rocker arm (hereinafter referred to as rocker arm), the rocker arm is first fixedly clamped onto the clamping mechanism 2. Specifically, the rocker arm is placed between two support plates 22, aligning the same side of the connecting holes at the front and rear ends of the rocker arm with the ends of the telescopic clamping rods 24 located at the front and rear ends of the same support plate 22. The rubber plugs 26 at the ends of the two telescopic clamping rods 24 are then inserted into the connecting holes at the front and rear ends of the rocker arm. While inserting the rubber plugs 26 into the connecting holes, the telescopic rods 242 are squeezed, causing the telescopic rods 242 to be in the fixed tube 241. The rocker arm slides inward toward the support plate 22 and presses against the clamping spring 243, aligning the other ends of the connecting holes at the front and rear ends with the ends of the positioning clamp 23 and the telescopic clamp 24 respectively, which are set on another support plate 22. Under the restoring force of the clamping spring 243, the rubber plugs 26 at the ends of the positioning clamp 23 and the remaining telescopic clamp 24 are inserted into the connecting holes at the front and rear ends of the rocker arm. In this way, the rubber plugs at the ends of the positioning rods are inserted into the connecting holes of the rocker arm to provide positioning for the rocker arm and prevent it from jerking between the two support plates 22. The telescopic rods 242 of the three telescopic clamps 24 are under the action of the clamping spring 243. The rubber plug 26 at the end of the telescopic rod 242 is held in the connecting hole, thereby clamping and fixing the rocker arm between the two support plates 22. Then, the motor 14 drives the synchronous belt 13 to drive the sliding seat 21 to slide on the linear slide rail 11. The sliding seat 21 then drives the support plate 22 and the rocker arm clamped between the two support plates 22 to move towards the painting mechanism 3. During the movement of the sliding seat 21, the gear 27 and the rack 12 cooperate to drive the rotating shaft 25 to rotate on the sliding seat 21, which in turn drives the support plate 22 to rotate the rocker arm. This allows the rocker arm to rotate while moving towards the painting mechanism 3. After entering the spray booth 31, the paint sprayed by the nozzle 32 is evenly sprayed onto the surface of the rocker arm in conjunction with the movement and rotation of the rocker arm, thus achieving the painting treatment of the rocker arm. Furthermore, since the port of the rocker arm's connection hole is blocked by the rubber plug 26, it can prevent paint from entering the connection hole of the rocker arm during the painting process. It can be seen that through the above structure and process, the rocker arm can be evenly painted to ensure the painting effect. Moreover, during the painting process, it is only necessary to fix the rocker arm to the clamping mechanism 2 and remove the rocker arm from the clamping mechanism 2. The operation process is relatively convenient and can effectively improve the efficiency of motorcycle rocker arm painting.

[0024] Additionally, each of the two support plates 22 has an adjustment plate 28 at its rear end. Two sliding rods 281 are formed on the adjustment plate 28. The sliding rods 281 pass through the adjustment grooves 221 opened on the support plate 22 and are screwed with adjustment nuts 282. The fixing tube 241 of the telescopic clamping rod 24 located at the rear end of the support plate 22 is fixedly connected to the adjustment plate 28. Loosening the adjustment nuts 282 allows the sliding rods 281 to slide in the adjustment grooves 221, thereby adjusting the position of the adjustment plate 28 on the support plate 22. This allows for adjustment of the distance between the two telescopic clamping rods 24 on the same support plate 22 or between the telescopic clamping rod 24 and the positioning clamping rod 23, to accommodate the painting of motorcycle rocker arms of different sizes, thus providing better applicability.

[0025] In addition, a first reinforcing rod 222 is fixedly connected between the front ends of the two support plates 22. The first reinforcing rod 222 connects the two support plates 22 to form a whole, which enhances the stability of the support plates 22 when driving the motorcycle rocker arm to rotate.

[0026] In addition, a second reinforcing rod 283 is fixedly connected between the two adjustment plates 28. The second reinforcing rod 283 enhances the stability of the motorcycle rocker arm when the support plate 22 drives it to rotate, and at the same time, it enables the two adjustment plates 28 to move synchronously when adjusting their positions on the support plate 22, which facilitates the operation during adjustment.

[0027] Furthermore, both the positioning clamp 23 and the telescopic rod 242 have snap-fit ​​protrusions 29 formed on their end peripheral surfaces. The inner wall of the connection hole on the end face of the rubber plug 26 has a snap-fit ​​groove 261 that matches the snap-fit ​​protrusion 29. The snap-fit ​​protrusion 29 snaps into the snap-fit ​​groove 261. The snap-fit ​​protrusion 29 and the snap-fit ​​groove 261 enable the rubber plug 26 to be detachably connected to the positioning clamp 23 or the telescopic rod 242, and the connection is relatively firm. When painting motorcycle rocker arms with connection holes of different diameters, the rubber plug 26 can be replaced for adaptation, thus providing better applicability.

[0028] Additionally, the frame 1 is equipped with a drying mechanism 4 located behind the painting mechanism 3. The drying mechanism 4 includes a drying chamber 41 mounted on the frame 1 and a hot air blower 42 connected to the interior of the drying chamber 41. After the motorcycle rocker arm completes the painting process in the painting chamber 31, it moves and rotates into the drying chamber 41, where the paint is dried by the hot air blower 42, thereby improving the efficiency of the painting process.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
