Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of lamps, and particularly to a follow-up support and flap blanking linkage device for a laser pipe cutting machine. Background Art
[0002] With the market demand, there is an urgent need to improve the economy and working efficiency of laser pipe cutting machines. The follow-up support during laser cutting and the flipping blanking device after the profile is cut are important factors affecting these two indicators. Among them, the commonly used blanking supports include variable-diameter wheels and flap follow-up supports. Among them, the flap follow-up support mechanism is applicable to more application scenarios and is widely used. It includes two actions. One is the servo follow-up in the vertical direction to support the profile being cut in real time, and the other is the horizontal flipping of the receiving plate to introduce the cut pipe into the material box. Generally, the servo follow-up in the vertical direction is driven by a servo motor, and the flipping action is usually completed by a cylinder. However, the structure of the servo motor plus the cylinder action not only affects the efficiency but also raises the equipment cost. Summary of the Invention
[0003] In order to solve the technical defects existing in the prior art, the present invention provides a follow-up support and flap blanking linkage device for a laser pipe cutting machine. Only one drive in the vertical direction is required to realize the two actions of support in the vertical direction and blanking flipping, which improves the efficiency and reduces the cost at the same time.
[0004] The technical solution adopted by the present invention is: a follow-up support and flap blanking linkage device for a laser pipe cutting machine, including a base. A linear guiding mechanism and a driving mechanism in the vertical direction are provided on the base. The linear guiding mechanism includes a lifting seat. The driving mechanism drives the lifting seat to move longitudinally up and down. A receiving flap is provided at the top of the lifting seat. One end of the receiving flap is hinged to the lifting seat, and the other end is a free end. A flipping driving assembly is also provided on the base. When the lifting seat descends to the height of the flipping driving assembly, the flipping driving assembly provides a flipping torque for the receiving flap. The receiving flap includes a horizontal position that provides a supporting force for the workpiece during the cutting process and a blanking position that is flipped by a certain angle around the hinge axis under the action of the flipping torque to introduce the workpiece into the next working station.
[0005] A hinge mechanism is provided at one end of the receiving flap. The receiving flap is movably installed on the lifting seat through the hinge mechanism, and the other end of the receiving flap is a movable end.
[0006] The driving mechanism is a linear driving mechanism, and the linear driving mechanism is one of a sprocket and chain mechanism, a gear and rack mechanism, and a lead screw mechanism.
[0007] The flipping driving assembly is composed of a cam mechanism or a lever mechanism.
[0008] When the lifting seat driven by the driving mechanism descends to a certain height, the movable end of the material receiving flap on the lifting seat is blocked by the cam mechanism, causing the material receiving flap to rotate by an angle α around the center of the hinge mechanism.
[0009] The lever mechanism includes an L-shaped structure composed of a long arm and a short arm. First and second cams are respectively provided at both ends of the long arm and the short arm of the L-shaped structure. The intersection of the long arm and the short arm is a rotary support point, and the L-shaped structure rotates around the rotary support point.
[0010] One end of the short arm of the L-shaped structure is close to one end of the hinge mechanism of the material receiving flap, and one end of the long arm of the L-shaped structure is close to the movable end of the material receiving flap.
[0011] The L-shaped structure includes a first position where the first and second cams on the long arm and the short arm are at the same horizontal height, and a second position where one end of the short arm is pressed down by one end of the hinge mechanism of the material receiving flap and one end of the long arm rotates upward around the rotary support point.
[0012] When the lifting seat driven by the driving mechanism descends to a certain height, one end of the hinge mechanism of the material receiving flap on the lifting seat presses down the second cam on the short arm, causing the L-shaped structure to flip around the rotary support point. The first cam on the long arm lifts upward to push the movable end of the material receiving flap to flip upward until it forms the required angle α with the horizontal plane.
[0013] The beneficial effects of the present invention are as follows: The present invention provides a follow-up support and flap blanking linkage device for a laser pipe cutting machine, including a base. A linear guiding mechanism and a driving mechanism in the vertical direction are provided on the base. The linear guiding mechanism includes a lifting seat. The driving mechanism drives the lifting seat to move vertically up and down. A material receiving flap is provided at the top of the lifting seat. One end of the material receiving flap is hinged to the lifting seat, and the other end is a free end. A flipping driving assembly is also provided on the base. When the lifting seat descends to the height of the flipping driving assembly, the flipping driving assembly provides a flipping torque for the material receiving flap. The material receiving flap includes a horizontal position that provides a supporting force for the workpiece during the cutting process and a blanking position that rotates by a certain angle around the hinge axis under the action of the flipping torque to guide the workpiece into the next working station. Through the cam mechanism or lever mechanism of the flipping driving assembly of the present invention, and through the driving force in the vertical direction, the linkage actions of follow-up material receiving and flipping and blanking are completed, thereby improving efficiency and saving costs at the same time.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Embodiment 1 A follow-up support and flap blanking linkage device for a laser pipe cutting machine, comprising a base 1. A linear guiding mechanism and a driving mechanism in the vertical direction are provided on the base 1. The driving mechanism is a linear driving mechanism, and the linear driving mechanism is one of a sprocket and chain mechanism, a gear and rack mechanism, and a lead screw mechanism. The linear guiding mechanism includes a lifting seat 2. The driving mechanism drives the lifting seat 2 to move vertically up and down. A receiving flap 3 is provided at the top of the lifting seat 2. One end of the receiving flap 3 is hinged to the lifting seat 2, and the other end is a free end. The receiving flap has two functions. One is to provide a certain supporting force for the workpiece during the cutting process, and at this time it is in a horizontal state. The other is to hold the cut workpiece and descend and flip by a certain angle after cutting to introduce the workpiece into the next working station. A hinge mechanism 31 is provided at one end of the receiving flap 3. The receiving flap 3 is movably installed on the lifting seat 2 through the hinge mechanism 31, and the other end of the receiving flap 3 is a movable end. A flipping driving assembly is further provided on the base 1. The flipping driving assembly is composed of a cam mechanism 4. When the lifting seat 2 descends to the height of the flipping driving assembly, the flipping driving assembly provides a flipping torque for the receiving flap 3. The receiving flap 3 includes a horizontal position for providing support for the workpiece during cutting and a blanking position for flipping by a certain angle around the hinge axis under the action of the flipping torque to introduce the workpiece into the next working station. When the lifting seat 2 is driven by the driving mechanism to descend to a certain height, the movable end of the receiving flap 3 on the lifting seat 2 is blocked by the cam mechanism 4, so that the receiving flap 3 rotates by an angle α around the center of the hinge mechanism 31. This device only uses one driving mechanism in the vertical direction to complete two actions of follow-up lifting and flipping. The vertical movement stroke S is divided into two parts, as Figure 4 shown. Among them, for the upper part of the stroke, within this range, the receiving flap is in a horizontal state and can stably support the workpiece. As the workpiece rotates, through servo drive, the receiving plate is always kept in real-time contact with the outer contour of the workpiece to achieve follow-up support. For the lower part of the stroke, within this range, real-time follow-up support is not required, the flap gradually flips, and an angle α is formed at the lowest point of the stroke. This angle must ensure that the workpiece can slide to the next working station under the action of gravity and overcome friction.
[0023] Embodiment 2 A follow-up support and flap blanking linkage device for a laser pipe cutting machine, comprising a base 1. A linear guiding mechanism and a driving mechanism in the vertical direction are provided on the base 1. The driving mechanism is a linear driving mechanism, and the linear driving mechanism is one of a sprocket and chain mechanism, a gear and rack mechanism, and a lead screw mechanism. The linear guiding mechanism includes a lifting seat 2. The driving mechanism drives the lifting seat 2 to move vertically up and down. A receiving flap 3 is provided at the top of the lifting seat 2. One end of the receiving flap 3 is hinged to the lifting seat 2, and the other end is a free end. The receiving flap has two functions. One is to provide a certain supporting force to the workpiece during the cutting process, and at this time it is in a horizontal state. The other is to hold the cut workpiece and descend and rotate a certain angle after the cutting is completed, and guide the workpiece into the next working station. A hinge mechanism 31 is provided at one end of the receiving flap 3. The receiving flap 3 is movably installed on the lifting seat 2 through the hinge mechanism 31, and the other end of the receiving flap 3 is a movable end. A flip driving assembly is further provided on the base 1. The flip driving assembly is composed of a lever mechanism 5. When the lifting seat 2 descends to the height of the flip driving assembly, the flip driving assembly provides a flip torque to the receiving flap 3. The receiving flap 3 includes a horizontal position for providing support to the workpiece during the cutting process and a blanking position for rotating a certain angle around the hinge axis under the action of the flip torque to guide the workpiece into the next working station. When the lifting seat 2 is driven by the driving mechanism to descend to a certain height, the movable end of the receiving flap 3 on the lifting seat 2 is blocked by the cam mechanism 4, so that the receiving flap 3 rotates an angle α around the center of the hinge mechanism 31.
[0024] The described lever mechanism 5 includes an L-shaped structure composed of a long arm 51 and a short arm 52. At both ends of the long arm 51 and the short arm 52 of the L-shaped structure, a first cam 53 and a second cam 54 are respectively provided. The intersection of the long arm 51 and the short arm 52 is a rotary support point 55, and the L-shaped structure rotates around the rotary support point 55. One end of the short arm 52 of the L-shaped structure is close to one end of the hinge mechanism 31 of the material receiving flap 3, and one end of the long arm 51 of the L-shaped structure is close to the movable end of the material receiving flap 3. The L-shaped structure includes a first position where the first cam 53 and the second cam 54 on the long arm 51 and the short arm 52 are at the same horizontal height, and a second position where one end of the hinge mechanism 31 of the material receiving flap 3 presses down one end of the long arm 51, causing the long arm 51 to rotate upward around the rotary support point 55. When the lifting seat 2 is driven by the driving mechanism to descend to a certain height, one end of the hinge mechanism 31 of the material receiving flap 3 on the lifting seat 2 presses down the second cam 54 on the short arm 52, causing the L-shaped structure to flip around the rotary support point 55, and the first cam 53 on the long arm 51 lifts upward to push the movable end of the material receiving flap 3 to flip upward until it forms an angle α required with the horizontal plane. This device only uses a driving mechanism in the vertical direction to complete two actions of follow-up lifting and flipping. The vertical movement stroke S is divided into two parts. As Figure 6 shown, when the lifting seat descends a certain height, both the first cam and the second cam are in contact with the material receiving flap. When the lifting seat 4 continues to descend, the lever will rotate around its rotary support point by a certain angle. Then, through the contact between the first cam and the second cam and the material receiving flap, the material receiving flap is pushed until it forms an angle α required with the horizontal plane. The design of the lever mechanism solves the defect that when the vertical stroke is limited by space, the cam mechanism may not be able to form a large enough angle.
