Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, and in particular to a variable-angle automatic cutting device. Background Art

[0002] In the production and assembly process of steel structures, it is usually necessary to accurately cut the steel according to a predetermined angle and then weld and assemble it. This process requires a high degree of accuracy and stability to ensure the quality and safety performance of the final product. However, most cutting equipment on the market still uses a manual structure design, which is not only cumbersome to operate when adjusting the cutting angle, but also difficult to achieve precise control, which directly leads to low work efficiency and increased production costs. Faced with this industry challenge, improving production efficiency has become a common goal pursued by all technicians in related fields. To this end, it is particularly urgent to develop a new cutting device that can automatically adjust the cutting angle.

[0003] A Chinese patent (publication number: CN219402605U) discloses a new type of double-head arbitrary compound angle cutting machine; the patent includes a frame, a clamping and fixing device installed on the frame for clamping and fixing the product to be cut, and an arbitrary compound angle cutting device arranged at both ends of the clamping and fixing device and fixed on the frame, and the arbitrary compound angle cutting device includes a saw blade capable of adjusting the position in the XYZ direction, the horizontal angle, and the vertical angle, and can perform universal angle cutting actions; in actual use, it is found that the patent adjusts the cutting angle of the saw blade in the horizontal plane through the first rotating platform. During the adjustment, the saw blade will deviate from the workpiece to be cut, and the position of the workpiece to be cut needs to be adjusted multiple times. For longer steel components, their own weight is large, and the adjustment of the position is more difficult, time-consuming and labor-intensive; therefore, it is urgently necessary to develop an automatic cutting device that can freely adjust the saw blade angle in the horizontal and vertical planes while ensuring that the saw blade is always accurately aligned with the workpiece to be cut, so as to improve the cutting accuracy and work efficiency. Summary of the invention

DETAILED DESCRIPTION

[0020] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0021] Embodiment 1, in combination with Figures 1 to 3 A variable angle automatic cutting device comprises a cutting mechanism 1 and a conveying platform 2; both sides of the cutting mechanism 1 are provided with a supporting platform 2 for supporting a workpiece to be cut, that is, the workpiece to be cut can be placed on the supporting platform 2 when cutting the workpiece; as shown in the attached Figure 3 As shown, the cutting mechanism 1 comprises a support 1-1, an electric slide 1-2 and a cutting machine 1-3; an electric slide 1-2 driven by a motor is provided on the top of the support 1-1, and the electric slide 1-2 is connected to the support 1-1 at an adjustable angle through a first rotating indexing plate 1-4, that is, the deflection angle of the electric slide 1-2 in the vertical plane can be adjusted through the first rotating indexing plate 1-4; The sliding seat of the electric slide 1-2 is fastened with a right-angle bracket 1-5, and a mounting bracket 1-6 is provided at one end of the right-angle bracket 1-5 away from the electric slide 1-2. The mounting bracket 1-6 is connected to the right-angle bracket 1-5 at an adjustable angle through a second rotating indexing plate 1-7; the mounting bracket 1-6 is installed with a cutting machine 1-3 for cutting workpieces, and the center of the cutting blade of the cutting machine 1-3 coincides with the rotation axis of the second rotating indexing plate 1-7; that is, the mounting bracket 1-6 can be driven to rotate by the second rotating indexing plate 1-7, thereby driving the cutting machine 1-3 to rotate, and adjusting the cutting angle of the cutting blade of the cutting machine 1-3 in the horizontal plane; It should be noted that when the workpiece to be cut is placed under the cutting machine 1-3, the rotation axis of the second rotating dividing plate 1-7 passes through the workpiece to be cut, and the center of the cutting blade of the cutting machine 1-3 coincides with the rotation axis of the second rotating dividing plate 1-7. Therefore, when the cutting angle of the cutting blade of the cutting machine 1-3 in the horizontal plane is adjusted, the cutting blade will not deviate from the workpiece to be cut; when the cutting angle of the cutting blade of the cutting machine 1-3 in the vertical plane is adjusted by the first rotating dividing plate 1-4, the cutting blade will also not deviate from the workpiece to be cut, thereby enabling the cutting operation to be carried out quickly and improving the working efficiency.

[0022] In order to improve the cutting accuracy, a laser 1-9 for projecting a cutting line to the workpiece to be cut is installed on one side of the mounting bracket 1-6 through the connecting bracket 1-8, that is, a straight line can be projected by the laser 1-9, so that a part of the straight line projected by the laser 1-9 coincides with the cutting line of the cutting blade of the cutting machine 1-3, and the other part is projected on the workpiece to be cut, so that the position of the workpiece to be cut can be accurately located before cutting, and the cutting machine 1-3 and the electric slide 1-2 are started, and the electric slide 1-2 drives the cutting machine 1-3 to move close to the workpiece to be cut to perform automatic cutting operations; It should be noted that the laser 1-9 is connected to the connecting bracket 1-8 through the mounting bracket 1-6. Therefore, no matter at what angle the cutting blade of the cutting machine 1-3 is, it can ensure that the straight line projected by the laser 1-9 can overlap with the cutting blade of the cutting machine 1-3, thereby accurately indicating the cutting position and improving the cutting accuracy.

[0023] In order to facilitate the movement of the workpiece to be cut and prevent the workpiece to be cut from moving randomly during the cutting process, as shown in the attached Figure 2 As shown, the support platform 2 is a roller conveyor, which can facilitate the movement of the workpiece to be cut; a clamp 3 for clamping the workpiece to be cut is provided at one end of the support platform 2 corresponding to the cutting mechanism 1, that is, the workpiece to be cut can be clamped by the clamp 3 during the cutting operation; the clamp 3 is a bench vise, which has a simple structure but needs to be manually driven; or the clamp 3 includes a fixed chuck 3-1 that is fastened to one side of the support platform 2, and a movable chuck 3-3 driven by a telescopic rod 3-2 is provided on the other side of the support platform 2, and the telescopic rod 3-2 is fixedly connected to the support platform 2, that is, when the workpiece to be cut is placed in place, the movable chuck 3-3 can be driven by the telescopic rod 3-2 to move close to the fixed chuck 3-1, thereby achieving the purpose of clamping the workpiece to be cut; When in use, place the workpiece to be cut on the supporting platform 2, turn on the laser 1-9 to project the cutting line, adjust the position of the workpiece to be cut so that the cutting position falls on the cutting line projected by the laser 1-9, and then start the cutting machine 1-3 and the electric slide 1-2. The electric slide 1-2 drives the cutting machine 1-3 to move close to the workpiece to be cut to perform automatic cutting operations; adjust the deflection angle of the electric slide 1-2 in the vertical plane through the first rotating dividing plate 1-4, and then adjust the cutting angle of the cutting blade of the cutting machine 1-3 in the vertical plane; drive the mounting bracket 1-6 to rotate through the second rotating dividing plate 1-7, and then drive the cutting machine 1-3 to rotate, and adjust the cutting angle of the cutting blade of the cutting machine 1-3 in the horizontal plane; the first rotating dividing plate 1-4 and the second rotating dividing plate 1-7 are both existing electric adjustment dividing plates, so they can be fully automatically adjusted through program settings, thereby realizing automatic cutting operations.

[0024] Embodiment 2: In actual use, it is found that when cutting the end of a workpiece, the clamping position is far away from the end of the workpiece to be cut, and the cutting position of the workpiece is in a suspended state, which easily generates large vibrations during the cutting operation, resulting in reduced cutting accuracy. In order to solve this technical problem, this embodiment is further improved; Combined with Figure 1 , 3 and 4, a variable angle automatic cutting device, which is different from embodiment 1 in that, on the basis of embodiment 1, a support plate 1-10 for supporting the workpiece to be cut is provided below the support 1-1 corresponding to the cutting machine 1-3, and the support plate 1-10 is connected to the support 1-1 via a cantilever bracket 1-11, that is, the workpiece to be cut can be supported by the support plate 1-10, so as to avoid vibration of the workpiece to be cut due to suspension during the cutting operation; The support disk 1-10 includes a fixed seat and a rotating disk, the fixed seat is correspondingly connected to the cantilever bracket 1-11, the top of the fixed seat is rotatably connected to the rotating disk, and the top of the rotating disk is provided with a clearance groove, which can make way for the cutting blade of the cutting machine 1-3 when cutting the workpiece to avoid damaging the support disk 1-10; at the same time, the rotating disk is rotatably connected to the top of the fixed seat, so that the angle of the clearance groove on the rotating disk can be adjusted according to the cutting angle of the cutting blade of the cutting machine 1-3, so that the angle of the clearance groove coincides with the cutting blade of the cutting machine 1-3, so that the cutting blade of the cutting machine 1-3 falls into the clearance groove when cutting the workpiece; The support plate 1-10 is connected to the cantilever bracket 1-11 in an adjustable height through a telescopic cylinder 1-12, and a proximity switch 1-13 is provided on one side of the electric slide 1-2. Figure 4 As shown; after adjusting the cutting angle of the cutting blade of the cutting machine 1-3 in the vertical plane, the plane where the cutting blade of the cutting machine 1-3 is located is not perpendicular to the top of the support plate 1-10, and it will be imagined that the cutting blade of the cutting machine 1-3 cannot fall into the make way groove when cutting the workpiece. At this time, the position of the cutting blade of the cutting machine 1-3 can be detected by the proximity switch 1-13. When the cutting blade of the cutting machine 1-3 is about to contact the support plate 1-10, the sliding seat of the electric slide 1-2 triggers the proximity switch 1-13, sends a signal, controls the telescopic cylinder 1-12 to shorten, and then drives the support plate 1-10 to descend, avoiding the phenomenon of cutting the support plate 1-10.
