This process is time-consuming, and frequent manual intervention is needed to cut a single batch of raw materials, lacking automation. Therefore, those skilled in the art have provided a raw material cutting device for the production of shock-absorbing supports to address the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to provide a raw material cutting device for the production of shock absorber brackets, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Furthermore, the auxiliary components include a slide rail, auxiliary rollers, and a connecting plate.

The connecting plate is fixedly connected to the cutting ruler plate, and the auxiliary rollers are rotatably connected to the connecting plate.

[0007] Furthermore, the lower surface of the lifting frame is similarly provided with another set of slide rails, auxiliary rollers, and connecting plates.

[0008] Furthermore, the lifting assembly includes a bearing box, a threaded sleeve, and a threaded rod. The bearing box is fixedly connected to the lifting frame, and the threaded rod is rotatably connected to the bearing box. The threaded sleeve is threadedly connected to the surface of the threaded rod, and the surface of the threaded sleeve is fixedly connected to the lifting frame.

[0009] Furthermore, the lifting assembly also includes a transmission bevel gear and a transmission rod. The transmission rod is rotatably connected inside the bearing box, the upper end of the transmission rod is fixedly connected to a threaded rod, and the transmission bevel gear is fixedly connected to the surface of the transmission rod.

[0010] Furthermore, the lifting assembly also includes a second servo motor and a power bevel gear.

[0014] By adopting the above technical solution

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The auxiliary components employ a combination structure of slide rails, auxiliary rollers, and connecting plates, creating a stable yet flexible connection between the cutting board and the lifting frame. The slide rails precisely constrain the rolling trajectory of the auxiliary rollers, effectively preventing the cutting board from shifting or wobbling during movement, ensuring it maintains its preset posture and providing a precise dimensional reference for raw material cutting. Simultaneously, another set of identical auxiliary components is symmetrically arranged on the lower surface of the lifting frame, further enhancing the balance and stability of the cutting board installation and ensuring it does not detach from the device during downward pressure.

[0017] 2. In the lifting assembly, the second servo motor transmits power through the meshing of the power bevel gear and the transmission bevel gear, converting the rotational motion of the motor into the rotation of the threaded rod, thereby driving the lifting frame to complete the lifting action. The entire process does not require manual adjustment; precise and rapid height adjustment can be achieved solely through motor control, significantly shortening the equipment debugging time. The first servo motor drives the turntable to rotate, and the fixed shaft on the turntable drives the connecting rod to move, enabling automated reciprocating motion of the cutting actuator, thereby further improving the automation effect.

The central axis of the auxiliary roller 16 is rotatably connected to the connecting plate 17 through a bearing. The connecting plate 17 is fixedly connected to the side of the cutting ruler 15 by bolts, so that the cutting ruler 15 can slide flexibly along the slide rail 4 through the auxiliary roller 16.

The inner hole of the threaded sleeve 13 is machined with an internal thread that matches the threaded rod 14, and the two form a threaded meshing connection. At the same time, the outer wall of the threaded sleeve 13 is fixed to the corresponding connecting seat of the lifting frame 1 by welding, so that the rotation of the threaded rod 14 can be converted into the vertical movement of the threaded sleeve 13, thereby driving the lifting frame 1 to rise and fall synchronously. The upper end of the transmission rod 21 is fixedly connected to the lower end of the threaded rod 14 via a coupling.

[0027] In this embodiment, a workpiece fixing platform 6 is provided at the center of the inner side of the mounting frame 5. A workpiece with a cutting mechanism is mounted on the workpiece fixing platform 6 via an external fixing component. A first servo motor 12 is fixedly connected to the lifting frame 1 via an extension frame. A turntable 10 is provided at the output end of the first servo motor 12.

The workpiece fixing platform 6 is welded and fixed at the center of the inner side of the mounting frame 5. The upper surface of the workpiece fixing platform 6 is kept horizontal, and its dimensions are designed according to the specifications of common shock-absorbing bracket materials. An external fixing component is provided on the workpiece fixing platform 6, which can be a pneumatic gripper or a manual tightening bolt structure, to firmly fix the workpiece to be cut on the platform and avoid the material displacement during the cutting process, which would cause cutting errors. The first servo motor 12 is fixed to the side of the lifting frame 1 through the extension frame. The turntable 10 is fixed to the output shaft of the first servo motor 12 through the coupling.

[0028] First, the shock-absorbing support material to be cut is placed on the workpiece fixing platform 6 and firmly fixed by the external fixing component. According to the thickness of the material, the second servo motor 18 is started, and the height of the lifting frame 1 is adjusted by the lifting component to keep the cutting execution mechanism and the upper surface of the material at a suitable initial distance. At the same time, the first servo motor 12 and the cutting execution mechanism are started. The first servo motor 12 drives the cutting execution mechanism to perform reciprocating cutting motion to complete the automated cutting operation of the material. During the operation, the working stability is ensured by the guiding effect of the auxiliary component.

[0029] The auxiliary components adopt a combination structure of slide rail 4, auxiliary roller 16 and connecting plate 17, so that the cutting ruler 15 and the lifting frame 1 form a stable and flexible connection relationship. The slide rail 4 forms a precise constraint on the rolling trajectory of the auxiliary roller 16, effectively avoiding problems such as deviation and shaking of the cutting ruler 15 during movement, ensuring that the cutting ruler 15 always maintains the preset posture, and providing a precise dimensional reference for raw material cutting. Meanwhile, another set of identical auxiliary components is symmetrically arranged on the lower surface of the lifting frame 1, which further enhances the balance and stability of the cutting ruler 15 installation, ensuring that the cutting ruler 15 will not detach from the device during the downward pressing operation; the second servo motor 18 in the lifting assembly realizes power transmission through the meshing of the power bevel gear 19 and the transmission bevel gear 20, converting the rotational motion of the motor into the rotation of the threaded rod 14, thereby driving the lifting frame 1 to complete the lifting action. The whole process does not require manual adjustment, and precise and rapid height adjustment can be achieved solely through motor control, which greatly shortens the equipment debugging time; the first servo motor 12 drives the turntable 10 to rotate, and the fixed shaft 9 on the turntable 10 drives the connecting rod 8 to move, which can realize the automated reciprocating motion of the cutting execution mechanism, thereby further improving the automation effect.
