Description
Technical Field
[0001] The invention relates to the technical field of skylight flexible shaft processing, in particular to a shearing device for skylight flexible shaft processing. Background Art
[0002] A flexible shaft is a very low-rigidity, elastic, and freely bendable transmission shaft that can flexibly transmit rotational motion and torque to any position. The flexible shaft is named after its purpose. In mechanical design, it is used as a non-linear transmission or a transmission component between non-same planes. It can simplify the transmission machinery while having high transmission accuracy and a wide range of applications. In addition, the flexible shaft can also mitigate impact.
[0003] During the production of skylights, flexible shafts need to be installed. Since the purchased flexible shafts generally exceed the normal usage standards, the excess parts need to be cut off. Since the flexible shafts can be bent freely, it is difficult to fix them well. During the cutting process, they are prone to offset, resulting in reduced cutting accuracy. During the processing, the surface of the flexible shaft is also prone to damage. In order to solve the above problems, we propose a shearing device for processing skylight flexible shafts. Summary of the Invention

[0005] Preferably, the fixed roller includes a fixed frame, the inner surface of the fixed frame is rotatably connected to a rotating roller, the top of the inner surface of the fixed frame is rotatably connected to a rotating shaft, the outer surface of the rotating shaft is fixedly connected to an eccentric cylinder, and the soft shaft is fixed by the rotating roller and the eccentric cylinder.
[0006] Preferably, a rubber layer is fixedly connected to the outer surface of the eccentric cylinder, and an anti-rotation plate is fixedly connected to the side of the outer surface of the rotating shaft close to the fixed frame. The rubber layer increases the friction between the soft shaft and the eccentric cylinder, and the anti-rotation plate prevents the eccentric cylinder from rotating at an excessive angle.
[0007] Preferably, the anti-rotation plate includes a rotating rod and a semicircular plate, the outer surface of the rotating rod is fixedly connected to the outer surface of the rotating shaft, the outer surface of the semicircular plate is fixedly connected to the inner surface of the fixed frame, the inner surface of the semicircular plate is fixedly connected to a first spring, and the top of the first spring is fixedly connected to a curved block. When rotated to a certain angle, the semicircular plate will block the rotating rod, so that the rotation angle of the rotating rod is limited.
[0008] Preferably, the guide plate includes a base plate, the bottom of the base plate is fixedly connected to the top of the straight rod, the bottom of the base plate is fixedly connected to a U-shaped tube, the top of the U-shaped tube passes through the base plate and is slidably connected to a limiter, the top of the limiter rests against the flexible shaft, and the U-shaped tube keeps the limiters on both sides balanced.
[0009] Preferably, the limiter includes a slider, the outer surface of which is slidably connected to the inner surface of the U-shaped tube, the top of the slider is fixedly connected to a fixed plate, the top of the fixed plate is fixedly connected to an arc plate, and the side of the top of the fixed plate is fixedly connected to a fixed block. The limiter can limit the position of the flexible shaft.
[0010] Preferably, the anti-deflection column includes a cylinder, the top of the cylinder is fixedly connected to the bottom of the connecting plate, the bottom of the cylinder is slidably connected to a sliding rod, and the bottom of the sliding rod is fixedly connected to a cross plate. The anti-deflection column can press the soft shaft to prevent the soft shaft from deviating during the cutting process.
[0011] Preferably, the horizontal plate includes a curved plate, the top of the curved plate is fixedly connected to the bottom of the sliding rod, the bottom of the curved plate is fixedly connected to a square plate, the bottom of the square plate is rotatably connected to a pressure plate, the side of the square plate is fixedly connected to an anti-deflection rod, and the horizontal plate and the limiter fix the flexible shaft.
[0012] Preferably, the cylinder includes a straight cylinder and a fixed column, the top of the straight cylinder is fixedly connected to the bottom of the connecting plate, the bottom of the fixed column is fixedly connected to the top of the sliding rod, the top of the fixed column is fixedly connected to a second spring, and the top of the second spring is fixedly connected to a sliding column.

[0013] Preferably, a sliding groove is provided on the inner surface of the straight cylinder, the inner surface of the sliding column is slidably connected to a vertical rod, the top of the sliding column is fixedly connected to a fixing plate, the bottom of the fixing plate is fixedly connected to an elastic plate, and the outer surface of the elastic plate is slidably connected to the inner surface of the sliding groove. The elastic plate and the sliding groove cooperate so that when the force applied to the flexible shaft is too large, the anti-deflection column stops adding pressure to the flexible shaft.
[0014] The present invention provides a shearing device for processing a skylight flexible shaft. It has the following beneficial effects:
[0015] 1. The shearing device used for processing the skylight flexible shaft fixes the flexible shaft through a fixed roller. Since the eccentric cylinder is eccentric, the flexible shaft drives the eccentric cylinder to rotate, so that the distance between the eccentric cylinder and the rotating roller gradually increases, and the flexible shaft can pass between the two. When the flexible shaft passes back, the distance between the eccentric cylinder and the rotating roller will decrease, so that the eccentric cylinder will be tightly attached to the surface of the flexible shaft, pressing the flexible shaft and preventing the flexible shaft from moving.
[0016] 2. The shearing device for processing the sunroof flexible shaft uses an anti-rotation plate to prevent the eccentric cylinder from rotating at an excessive angle. If the eccentric cylinder rotates at an excessive angle, the distance between the eccentric cylinder and the rotating roller will no longer increase but begin to decrease. The anti-rotation plate will prevent the eccentric cylinder from continuing to rotate. At the same time, the anti-rotation plate will cause the eccentric cylinder to tend to rotate back, so that the eccentric cylinder can better fix the flexible shaft.
[0017] 3. The shearing device for processing the skylight flexible shaft prevents the flexible shaft from shifting during the cutting process through anti-deviation columns and limiters. The curved plate is attached to the bottom of the outer surface of the flexible shaft, and the horizontal plate moves downward and is attached to the top of the outer surface of the flexible shaft. The anti-deviation rod can be inserted into the small hole on the surface of the fixed block and overlap with the inner surface of the fixed block to prevent the position of the anti-deviation column from shifting. The curved plate and the horizontal plate fix the flexible shaft.
[0018] 4. The shearing device used for processing the skylight flexible shaft uses a cylinder to protect the surface of the flexible shaft. When the flexible shaft is subjected to force, the elastic plate will bend under the force to provide a buffer force. When the force on the surface of the flexible shaft is too large, the elastic plate will bend too much and will slide out of the slide groove, causing the sliding rod to slide directly upward. The surface of the flexible shaft is no longer subjected to force, preventing excessive force from scratching the surface of the flexible shaft. BRIEF DESCRIPTION OF THE DRAWINGS
