General-purpose industrial circular saws, although lower in cost, lack flexibility and cannot meet the machining requirements of complex trajectories. Robots or CNC machine tools, while highly flexible, significantly increase equipment investment and maintenance costs. Therefore, existing cutting methods struggle to achieve a balance between versatility, efficiency, and quality. Utility Model Content

[0025] Example 1

[0026] like Figures 1 to 3 As shown, Figure 1This is a schematic diagram (first view) of a rocker arm traveling and cutting device for a vehicle body exterior trim strip provided in an embodiment of this utility model; Figure 2 This is a schematic diagram (second view) of the structure of the rocker arm traveling and cutting device for the exterior trim strip of the vehicle provided in this embodiment of the utility model; Figure 3 This is a schematic diagram (third view) of the structure of the rocker arm traveling and cutting device for the exterior trim strip of the vehicle provided in this embodiment of the utility model; Figure 4 This is a schematic diagram of the structure of the driving component provided in an embodiment of this utility model.

[0027] In this embodiment, a vehicle exterior trim rocker arm traveling and cutting device includes: a traveling component 100, a rocker arm assembly 200, and a drive component 300; the traveling component 100 includes a cylinder assembly 120 and a floating joint 130; the rocker arm assembly 200 includes a die-cast rocker arm housing 210 and a support 220, the cylinder assembly 120 is connected to the second end of the die-cast rocker arm housing 210 through the floating joint 130, and the first end of the die-cast rocker arm housing 210 is hinged to the support 220; the drive component 300 includes a motor 310, a belt drive assembly 320, and a circular saw blade 330, the motor 310 drives the circular saw blade 330 to rotate through the belt drive assembly 320, and the second end of the die-cast rocker arm housing 210 is coaxially connected to the circular saw blade 330; wherein, the cylinder assembly 120 pushes the second end of the die-cast rocker arm housing 210 to swing in a straight line, and the second end of the die-cast rocker arm housing 210 drives the circular saw blade 330 to move along an arc trajectory.

[0028] In an optional embodiment, the traveling assembly 100 further includes a bracket 110, and the cylinder assembly 120 is fixed to the bracket 110 by a double-ear bracket. The cylinder assembly 120 includes a drive cylinder and multiple guide cylinders. The drive end of the drive cylinder 120 is connected to a floating joint 130, and the drive ends of the multiple guide cylinders move synchronously with the drive end of the drive cylinder. The guide cylinders are used to guide or buffer the drive cylinder, such as by using a damping cylinder.

[0029] In an optional embodiment, the floating joint 130 connects the drive end of the cylinder assembly 120 and the second end of the die-cast rocker arm housing 210, respectively, wherein the movement direction of the drive end of the cylinder assembly 120 is collinear with the movement direction of the second end of the die-cast rocker arm housing 210. For example, the floating joint 130 is a fisheye joint, used to ensure that the driving force of the cylinder assembly 120 is collinear with the movement direction of the second end of the die-cast rocker arm housing 210.

[0030] In an optional embodiment, the traveling assembly 100 further includes a proximity switch 140 connected to any cylinder, such as being disposed on the drive end of a driving cylinder, for controlling the stroke range L of the cylinder assembly 120, and controlling the swing range of the die-cast rocker arm housing 210 by controlling the stroke of the cylinder assembly 120. Specifically, the proximity switch 140 can be an inductive or capacitive proximity switch, triggering the switch action by detecting the position of the drive end of the cylinder, thereby controlling the stroke of the drive end of the cylinder. Alternatively, the proximity switch 140 can also be configured as a limit switch, triggering the switch action by detecting the stroke of the drive end of the cylinder, thereby controlling the stroke of the drive end of the cylinder.

[0031] The principle is that the driving end of the cylinder assembly 120 moves in a straight line, pushing the second end of the die-cast rocker arm housing 210 to also move in a straight line. At the same time, the die-cast rocker arm housing 210 swings around its connecting shaft with the support 220 as the rotation axis. The second end of the die-cast rocker arm housing 210 is coaxially connected to the circular saw blade 330, thereby driving the circular saw blade 330 to move along an arc trajectory. Specifically, since the first end of the die-cast rocker arm housing 210 is hinged to the support 220, when the cylinder assembly 120 pushes the second end of the die-cast rocker arm housing 210 to move in a straight line, the die-cast rocker arm housing 210 swings around the hinge point as the center, thereby driving the circular saw blade 330 to move along an arc trajectory, so that the cutting trajectory of the circular saw blade 330 is an arc curve trajectory, and its trajectory radius is determined by the relative position of the die-cast rocker arm housing 210 and the support 220. Finally, driven by the motor 310, the belt drive assembly 320 drives the circular saw blade 330 to rotate, realizing the dynamic cutting of the exterior trim strips of the vehicle body.

[0032] In one optional embodiment, the first end of the die-cast rocker arm housing 210 is rotatably connected to the support 220, causing the second end of the die-cast rocker arm housing 210 to swing about the rotation axis at one end of the support 220. Multiple deep groove ball bearings are embedded in the second end of the die-cast rocker arm housing 210, and a drive shaft passes through and connects to these bearings. Specifically, two deep groove ball bearings are provided, symmetrically arranged on both sides of the second end of the die-cast rocker arm housing 210. After passing through the multiple deep groove ball bearings, the drive shaft is coaxially and fixedly connected to the circular saw blade 330.

[0033] In one optional embodiment, the belt drive assembly 320 includes a drive pulley 321, a belt 322, and a driven pulley 323. The motor 310 is coaxially connected to the drive pulley 321, and the drive pulley 321 and the driven pulley 323 are driven by the belt 322. The driven pulley 323 and the circular saw blade 330 are fixedly connected to both ends of the drive shaft, with the driven pulley 323 fixedly connected to one end of the drive shaft and the circular saw blade 330 fixedly connected to the other end.

[0034] For example, the motor 310 can be a three-phase asynchronous motor with a rated speed of 2800 r / min, and it is fixed at the bottom. Multiple belts 322 are arranged in parallel, such as three belts, all of which are wedge belts. The motor 310 and the drive pulley 321 are connected by a key, and the driven pulley 323 is connected to the drive shaft by a key. The circular saw blade 330 is fixed to the end of the drive shaft. The motor 310, as a power source, outputs torque through its output shaft, which is transmitted to the driven pulley 323 through the drive pulley 321 and belts 322, achieving a speed change in transmission ratio. The driven pulley 323 then drives the circular saw blade 330 to rotate through the drive shaft, achieving high-speed rotation of the circular saw blade 330.

[0035] In one optional embodiment, the circular saw blades 330 are provided in two sets, which are arranged side by side and coaxially, and the spacing is adjustable, so as to realize simultaneous cutting of multiple parts on the exterior trim of the vehicle body.

[0036] In one optional embodiment, the body exterior trim rocker arm traveling and cutting device further includes a clamping assembly 400, in which the body exterior trim is clamped. The clamping assembly 400 includes a plurality of guide blocks for limiting the displacement of the body exterior trim. Furthermore, two sets of the body exterior trim rocker arm traveling and cutting devices of this embodiment can be arranged side-by-side, achieving symmetrical cutting at both ends of the body exterior trim through synchronous driving.

[0037] It is worth noting that the new vehicle body exterior trim rocker arm traveling cutting device, combining the dense tooth shape of the 330-tooth circular saw blade with the dynamic cutting flexibility of the rocker arm, solves the problem of mutual constraints between current processing efficiency and quality improvement, enhances the versatility and standardization of vehicle body exterior trim cutting equipment, and effectively solves the problems of difficulty in balancing efficiency and quality, high equipment cost and insufficient versatility in the existing technology.

[0038] Understandably, the vehicle exterior trim rocker arm cutting device of this embodiment can be used for cutting and processing exterior trim products such as passenger car bodies, commercial vehicles, and trucks, including bright trim strips, and is widely applicable to exterior trim parts made of different materials. Meanwhile, the rocker arm assembly 200 adopts a compact layout, enhancing the device's versatility, and its size is reduced by approximately one-third compared to similar products. The saw blade can also be quickly changed according to the material of the processed product to meet processing quality requirements. Furthermore, the cutting mechanism can be upgraded and modernized through the addition of intelligent components; for example, a servo motor can be used instead of a three-phase asynchronous motor, and a light grating can be used for protection and limit switching.

[0039] The working process of the rocker arm cutting device for the exterior trim strip in this embodiment is as follows: The exterior trim strip is supported and fixed by the clamping assembly 400 to ensure that the exterior trim strip does not shift during processing; the cylinder group 120 of the traveling assembly 100 applies a linear driving force to the rocker arm assembly 200 through a fisheye connector, and the proximity switch 140 controls the end position of the traveling cylinder group 120; when the cylinder group 120 starts, the rocker arm assembly 200 moves smoothly in a straight line, driving the circular saw blade 330 at the end of the drive shaft to approach the exterior trim strip. The three-phase asynchronous motor of the drive assembly 300 drives the driven wheel 323 through the driving wheel 321 and the belt 322, and the drive shaft drives the circular saw blade 330 to rotate at high speed with an amplified rotation speed. At the same time, the die-cast rocker arm housing 210 of the rocker arm assembly 200 swings, causing the circular saw blade 330 to cut into the exterior trim strip along an arc trajectory during linear travel. By combining linear thrust and rotational cutting force through dynamic cutting, the cutting force is evenly distributed, reducing tool wear. When the proximity switch 140 detects that the set endpoint has been reached, the cylinder assembly 120 stops advancing and retracts, and the circular saw blade 330 also retracts to its initial position, completing the cutting process of the exterior trim strip.

[0040] This utility model discloses a rocker arm traveling and cutting device for exterior trim strips. The traveling component drives the die-cast rocker arm housing to swing through the cooperation of a cylinder group and a floating joint. Combined with belt drive, it drives the circular saw blade to move along an arc trajectory, realizing the coordinated control of dynamic cutting and high-speed rotation. This not only simplifies the transmission structure and reduces equipment costs, but also adapts to the processing requirements of different exterior trim strips through the arc trajectory, significantly improving versatility and precision, and achieving a balance between versatility, efficiency and quality.
