Description

Technical Field

Furniture has also been continuously developing and innovating with the times. Today, there are many categories, different materials, complete varieties, and different uses. It is an important foundation for establishing a work and living space. In the furniture manufacturing process, metal accessories are needed to fix and connect the furniture. The furniture accessories positioning welding device is a device designed for the high-precision assembly requirements of metal connectors in furniture manufacturing. For example, patent (CN222114068U) discloses a welding device for processing metal parts. After the metal parts are fixed by the positioning plate in conjunction with the electric push rod, the support rod is rotated to make the bevel gear cooperate with the second bevel gear to rotate the lifting screw, so that the clamping plate screwed on the lifting screw can be displaced. In this way, multiple groups of clamping plates can be used to hold and fix the side of the metal parts, thus avoiding the problem of clamping offset of the parts, making it easier to weld them using the welding equipment. When using the above technology, we found that the following technical problems exist in the existing technology: the clamping plate can only make linear displacements, and the fixed metal parts cannot be rotated around the X or Y axis, resulting in manual intervention for angle adjustment during non-coplanar welding.

A triangular support frame 11 is fixed to each of its two output ends. A driving roller 13 is rotatably connected to the interior of the triangular support frame 11. A driven rotary roller 14 is rotatably connected to the top and bottom of one end of the triangular support frame 11. Tracks, such as synchronous belts, are provided on the outer sides of the driving roller 13 and the driven rotary roller 14. These tracks are meshed with synchronous pulleys.

At least two-thirds of the vertical length of the track is exposed above the upper surface of the welding table 1.

[0024] A rectangular through-slot is provided inside the welding table 1. The triangular support frame 11 is located inside the welding table 1 and is slidably connected to the welding table 1 through the rectangular through-slot. The rectangular through-slot allows the triangular support frame 11 to move inside the welding table 1, thereby enabling the two triangular support frames 11 to clamp metal fittings of different sizes. Here, the operation of the double-axis cylinder 15 enables the two triangular support frames 11 to move inside the welding table 1, thereby enabling the two triangular support frames 11 to clamp metal accessories of different sizes. The operation of the second drive motor 12 enables the active drive roller 13 to rotate. Through the setting of the two driven rotating rollers 14, the tracks outside the active drive roller 13 and the driven rotating roller 14 are rotated, thereby enabling the height of the metal accessories between the two triangular support frames 11 to be adjusted in position; and the two triangular support frames 11 are respectively provided with guide pairs in the moving direction with the welding table 1, such as guide rods and guide sleeves, or slide rails and sliders, etc.

[0025] Specifically, if Figure 11As shown, each triangular support frame 11 of this embodiment includes two parallel triangular blocks 110, and the two triangular blocks 110 are connected together via an active drive roller 13 and a driven rotating roller 14.

A rectangular bladder 112 is provided on the lifting movable partition plate 111, located in the subspace near the vertical side of the crawler. The bladder 112 is connected to an air pipe that passes through one of the triangular blocks 110.

[0026] When the height position of the metal accessories needs to be adjusted, air is inflated into the bladder 112 through the air tube, and then the bladder 112 in each triangular support frame 11 continues to expand, which will cause the vertical sections of the track to arch toward each other.

[0029] Here, the operation of the transverse hydraulic cylinder 31 enables the transverse sliding shaft 34 to move, thereby enabling the transverse sliding shaft 34 to move inside the rectangular guide groove, so that the transverse clamping column 32 can rotate around the longitudinal axis 33 as the center of the circle, thereby enabling the transverse clamping column 32 to clamp metal fittings of different sizes to be welded; The operation of the third drive motor 16 enables the circular rotating seat 17 to rotate inside the annular rotating platform 2. The rotation of the circular rotating seat 17 enables the horizontal support column 21 to rotate.

10. A welding method for positioning welding of furniture metal accessories, characterized in that: The method is applied to a furniture metal fitting positioning welding device according to any one of claims 1 to 9, and the method comprises the following steps: S1. Place one of the metal accessories between the two triangular support frames (11), and through the operation of the double-axis cylinder (15), the two triangular support frames (11) can be moved inside the welding table (1), so that the two triangular support frames (11) can clamp metal accessories of different sizes; S2. The second drive motor (12) operates to rotate the active drive roller (13). The two driven rotating rollers (14) are arranged to rotate the tracks on the outer sides of the active drive roller (13) and the driven rotating roller (14), thereby adjusting the height of the metal fittings between the two triangular support frames (11). S3. Place another metal fitting between the plurality of transverse clamping columns (32), and operate the transverse hydraulic cylinder (31) to enable the transverse sliding shaft (34) to move, thereby enabling the transverse sliding shaft (34) to move inside the rectangular guide groove, so that the transverse clamping column (32) can rotate with the longitudinal axis (33) as the center of the circle, thereby enabling the transverse clamping column (32) to clamp metal fittings to be welded of different sizes; S4. The first driving motor (9) operates to rotate the driving gear (10), and the rotation of the driving gear (10) causes the circular rotating ring (7) to rotate, thereby causing the circular rotating ring (7) to drive the annular rotating table (2) to rotate; S5. The third drive motor (16) operates to enable the circular rotating seat (17) to rotate inside the annular rotating table (2). The rotation of the circular rotating seat (17) enables the lateral support column (21) to rotate, thereby enabling the metal parts to be welded to rotate with the circular rotating seat (17) as the center of the circle; S6. The operation of the first vertical hydraulic cylinder (19) enables the vertical support column (20) to slide vertically on the outside of the rectangular limit column (18), thereby enabling the position height of the horizontal support column (21) to be adjusted; S7. The fourth drive motor (23) is operated to rotate the transverse threaded rod (24), thereby enabling the transverse sliding column (22) to move inside the transverse support column (21), thereby adjusting the transverse movement position of the transverse sliding column (22); S8. The second vertical hydraulic cylinder (25) operates to enable the longitudinal connecting column (26) to be vertically lifted and lowered. The vertical lifting of the longitudinal connecting column (26) enables the vertical sliding block (27) to be vertically lifted and lowered inside the vertical support column (20). The lifting of the longitudinal connecting column (26) enables the longitudinal rotating column (30) to be rotated inside the vertical support column (20) through the vertical transmission plate (28) and the rectangular rotating plate (29). The rotation of the longitudinal rotating column (30) enables the transverse support column (21) to be rotated. S9. After the two metal parts are fitted together, the two metal parts can be welded by the welding robot arm (5), and the operation of the industrial camera (6) can identify the real-time positions of the two metal parts.
