Description

Technical Field

At the same time, by rotating different numbers of turns, the fixing of aluminum alloy doors and windows of different widths can be achieved."

[0004] The above-mentioned device can only achieve simple placement and clamping. After fixing, when welding is required on the bottom of the workpiece, the workpiece needs to be removed and manually flipped, which affects the welding efficiency.

[0023] As described in the background art, the above-mentioned device can only achieve simple placement and clamping. After fixing, when welding is required on the bottom of the workpiece, the workpiece needs to be removed and manually flipped, which affects the welding efficiency.

[0024] To solve this technical problem, this utility model provides an aluminum alloy fixing device, which is applied to aluminum alloy welding and fixing;

[0025] The system includes an operating table 1, with a welding robot 2 and a welding table 3 mounted on its upper end. The welding table 3 is fixed to the operating table 1. Limiting frames 7 are symmetrically fixed to one end of the upper end of the welding table 3. A support plate 8 is movably connected between the two limiting frames 7. The outer side of the support plate 8 is in contact with the welding table 3. Limiting guide posts 13 and screws 14 are mounted on the upper end of the side of the welding table 3 away from the welding robot 2. Both the limiting guide posts 13 and screws 14 are fixed to the limiting frames 7. A pusher seat 15 is provided between the limiting guide posts 13 and screws 14. The pusher seat 15 is slidably connected to the limiting guide posts 13. A drive assembly is provided between the pusher seat 15 and screws 14. A turntable 16 is rotatably connected to the inner side of the pusher seat 15.

[0026] The aluminum alloy fixing device provided by this utility model, through the overall structural design, controls the pusher seat 15 to move closer to the support plate 8 to compress the workpiece. At this time, by controlling the rotation of the support plate 8, the workpiece can be automatically flipped over, which facilitates welding operations on the bottom of the workpiece and effectively ensures welding efficiency.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example 1

[0029] Please refer to Figure 1-4 An aluminum alloy fixing device includes an operating table 1. A welding robot 2 and a welding table 3 are respectively arranged on the upper end of the operating table 1. The welding table 3 is fixed to the operating table 1. Limiting frames 7 are symmetrically fixed at one end of the upper end of the welding table 3. A support plate 8 is movably connected between the two limiting frames 7. The outer side of the support plate 8 is in contact with the welding table 3. Limiting guide posts 13 and screws 14 are respectively arranged on the upper end of the side of the welding table 3 away from the welding robot 2. The limiting guide posts 13 and screws 14 are both fixed to the limiting frames 7. A pusher seat 15 is arranged between the limiting guide posts 13 and screws 14. A turntable 16 is rotatably connected to the inner side of the pusher seat 15. The pusher seat 15 is slidably connected to the limiting guide posts 13. In order to facilitate the drive of the pusher seat 15 to move closer to the support plate 8, a drive assembly is arranged between the pusher seat 15 and the screws 14, thereby facilitating the clamping of the workpiece.

[0030] Specifically, the drive assembly includes a hollow screw cylinder 18. The hollow screw cylinder 18 is rotatably connected inside the pusher seat 15 and located outside the screw 14. The hollow screw cylinder 18 is threadedly connected to the screw 14. A third spur gear 19 is fixed to the outer side of the hollow screw cylinder 18 at the end away from the support plate 8. A second geared motor 20 is fixed inside the pusher seat 15 and located outside the third spur gear 19. A fourth spur gear 21 is fixed to the output end of the second geared motor 20. The fourth spur gear 21 is meshed with the third spur gear 19.

[0031] In order to further increase the friction between the workpiece and the workpiece and make the clamping more stable when clamping the workpiece, a first support pad 10 is fixed at one end of the support plate 8 near the push seat 15, and a second support pad 17 is fixed at one end of the turntable 16 near the first support pad 10. After the workpiece is clamped between the first support pad 10 and the second support pad 17, in order to facilitate the automatic flipping of the workpiece and thus facilitate the welding operation on the bottom of the workpiece, an extension seat 6 is fixed at the lower end of the welding table 3 near the limit frame 7. A first reduction motor 11 is fixed at one end of the extension seat 6. A second spur gear 12 is fixed at the output end of the first reduction motor 11. A first spur gear 9 is fixed on the inner side of the support plate 8. The first spur gear 9 and the second spur gear 12 are meshed and connected. Example 2

[0032] The aluminum alloy fixing device provided in Example 1 has been further optimized, specifically, as follows: Figure 1-2 As shown, before clamping, in order to facilitate the support of the placed workpiece, a material placement platform 5 is provided on the inner side of the welding table 3 and between the first support pad 10 and the second support pad 17. Before and after clamping, in order to facilitate raising the height of the workpiece placement position, an electric telescopic rod 4 is fixed at the upper end of the operating table 1 and at the lower end of the material placement platform 5. The telescopic end of the electric telescopic rod 4 is fixed to the material placement platform 5, so that after the workpiece is clamped and the material placement platform 5 is controlled to move down, it is convenient to make the workpiece and the welding table 3 separated by a certain distance, thereby facilitating the automatic flipping of various types of workpieces.

[0033] All of the above electrical components are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail here.

[0034] The aluminum alloy fixing device provided by this utility model is used as follows: After the aluminum alloy workpiece is placed on the upper end of the material placement table 5, the second reduction motor 20 is started to drive the fourth flat gear 21 to rotate. The fourth flat gear 21 meshes with the third flat gear 19, which drives the hollow screw barrel 18 to rotate and cooperates with the threaded connection between the hollow screw barrel 18 and the screw 14. This drives the pusher seat 15 to move towards the support plate 8 through the guidance of the limiting guide post 13, so that the second support pad 17 contacts the aluminum alloy workpiece and continuously pushes the aluminum alloy workpiece, so that the end away from the second support pad 17 contacts the first support pad 10, thereby clamping the aluminum alloy workpiece between the first support pad 10 and the second support pad 17.

[0035] After the aluminum alloy workpiece is clamped, the telescopic end of the electric telescopic rod 4 is retracted, thereby resetting the material placement table 5. At this time, there is a certain distance between the aluminum alloy workpiece and the material placement table 5 and the welding table 3. When welding is required at the bottom of the aluminum alloy workpiece during the welding process, the first reduction motor 11 is started to drive the second spur gear 12 to rotate. Through the meshing of the second spur gear 12 and the first spur gear 9, the support plate 8 is driven to rotate between the two limit frames 7. With the rotational connection between the turntable 16 and the pusher seat 15, it is convenient to drive the aluminum alloy workpiece to automatically flip over without manual unloading and flipping, effectively ensuring welding efficiency.
