Description

Technical Field

[0001] The present invention relates to the technical field of numerically controlled machine tools, and in particular to an intelligent synchronously driven numerically controlled machine tool and a control method thereof. Background Art

[0002] In modern industrial production, CNC machine tools are widely used in various manufacturing fields due to their high precision and high efficiency. Especially in the field of welding, CNC machine tools can achieve precise welding of complex workpieces, improve production efficiency and product quality. However, existing CNC machine tools still have some limitations in achieving welding gun angle adjustment and workpiece clamping.

[0003] Traditional CNC machine tools usually use simple linear moving components to achieve the position adjustment of the welding gun, which limits the adjustment ability of the welding gun in space and is difficult to meet the needs of complex welding tasks. In addition, the workpiece is clamped by mechanical clamps, which not only increases the complexity of the operation, but also makes it difficult to accurately control the clamping force, affecting the accuracy and stability of welding. After searching, a high-precision welding CNC machine tool with application number CN202310363455.9, which involves the technical field of welding CNC machine tools, includes a base and a recycling box. The main body of the base is a rectangular structure, and the front and rear sides of the base are provided with transverse grooves. A motor A is installed on the left side of the base to solve the problem that the existing welding CNC machine tools lack an effective guide structure when performing welding operations, which makes it easy to affect welding due to the lack of an effective warning structure when the welding wire is exhausted. The effect of the above-mentioned patent is limited. The electric push rod B installed in the recycling box is started to push the stage to the left until the stage moves to the position directly above the collection box for placement. At this time, the sprayer installed in the collection box is synchronously started to spray upward to quickly cool the workpiece, thereby achieving the purpose of being more convenient for subsequent processing. The above-mentioned patent can only adjust the position of the welding head, but cannot adjust the angle of the welding head. When the fixture clamps the workpiece, it is necessary to manually rotate the limit rod installed on the outside of the limit frame and the parts inserted into the limit frame to perform clamping and limiting operations, which is not smart and convenient enough. In addition, the clamping force cannot be adjusted by manual clamping.

[0040] The welding gun angle adjustment assembly includes a square plate 15, and the square plate 15 is fixedly connected to the support plate 13 and the reinforcement plate 14;

[0041] The welding gun angle adjustment assembly also includes a connecting block 16, which is fixed in the middle of the lower edge of the square plate 15. There are four connecting blocks 16 arranged in a rectangular shape.

[0042] In this embodiment, to adjust the angle of the welding gun 24, it is first necessary to operate the arc slide bar 20 to make it slide in the arc slide 17. The movement of the arc slide bar 20 will drive the connected movable plate 26, thereby affecting the position of the arc slot bar 1 23 and the arc slot bar 2 29.

[0044] In this embodiment, the motor 18 is a stepper motor. By starting the motor 18, the output shaft of the motor 18 drives the worm wheel 22 to rotate through the support seat 19. Since the worm wheel 22 is meshed with the worm 21, the rotation of the worm wheel 22 is transmitted through the worm 21, thereby driving the moving plate 26 to move along the arc slide 17. The movement of the moving plate 26 will cause the positions of the arc groove rod 1 23 and the arc groove rod 29 to change. Since the arc groove rod 1 23 and the arc groove rod 29 are arranged in a cross shape, their relative movement can realize the movement of the welding gun 24.

[0045] The upper side of the base 6 is fixedly connected to the welding platform 1 through a symmetrical supporting pipe 30, and the welding platform 1 is connected to the clamping assembly.

[0046] The clamping assembly includes a linear slide 11 opened in the middle of the upper side of the welding platform 1, a symmetrical sliding block 8 is arranged in the linear slide 11, a screw 12 is arranged in the linear slide 11, two ends of the screw 12 are respectively rotatably connected to the two ends of the linear slide 11, the screw 12 is threadedly matched with the two sliding blocks 8 through two sections of reverse threads, the welding platform 1 is fixedly connected to the motor 2 9, the output shaft of the motor 2 9 is fixedly connected to one end of the linear slide 11, the upper side of the sliding block 8 is fixedly connected to the middle part of the electromagnetic block support rod 7, and the opposite side of the electromagnetic block support rod 7 is respectively connected to the electromagnetic block 10.

[0047] In this embodiment, the motor 2 9 is a stepper motor, and the clamping assembly can clamp the frame structure that needs to be welded. By starting the motor 2 9, the output shaft of the motor 2 9 rotates to drive the screw 12 to rotate, the screw 12 drives the sliding block 8 to move, the sliding block 8 drives the electromagnetic block support rod 7 and the electromagnetic block 10 to move, and the electromagnetic block 10 clamps both sides of the frame structure to fix the frame structure.

The central axis of the electromagnetic block 10 is rotatably connected to the electromagnetic block support rod 7. A pressure sensor 101 is arranged at one end of the central axis of the electromagnetic block 10. When the electromagnetic block 10 abuts against the frame to be welded, the pressure sensor 101 starts to detect the pressure signal, controls the rotation of the motor 2 9 through the controller, and then controls the clamping force to improve the welding accuracy.

The rotation of the worm gear 22 is transmitted through the worm 21 to drive the moving plate 26 to move. The moving plate 26 drives the arc slide bar 20 to move along the arc slideway 17. The movement of the moving plate 26 affects the positions of the arc slot rod 1 23 and the arc slot rod 2 29. The arc slide block 1 28 and the arc slide block 2 27 can move in the arc slot rod 1 23 and the arc slot rod 2 29 respectively. When the arc slot rod 29 moves, the arc slide block 1 28 is driven to move along the arc slot rod 1 23 through the arc slide block 27.

After the adjustment is completed, turn off the motor 18.

[0057] Step 3: By starting the motor 2 9, the output shaft of the motor 2 9 rotates to drive the screw 12 to rotate, the screw 12 drives the sliding block 8 to move, and then drives the electromagnetic block support rod 7 and the electromagnetic block 10 to move, so as to clamp the workpiece, and then perform welding work through the welding gun 24;

[0058] Step 4: After welding is completed, the output shaft of the control motor 2 9 is rotated in the reverse direction to drive the electromagnetic block 10 to move in the reverse direction, release the workpiece, and take the workpiece away.

[0059] Among them, in the step three, when the electromagnetic block 10 abuts against the workpiece, the pressure sensor 101 starts to detect the pressure signal, and the controller controls the clamping force of the electromagnetic block 10 by controlling the output shaft rotation of the motor 2 9 according to the signal of the pressure sensor 101.
