[0002] There are many methods for surface treatment of aluminum alloys, such as physical method, chemical method, physical-chemical method and comprehensive method. The commonly used method now is anodizing, which forms a conversion film on the surface of aluminum alloy by electrochemical method. Although this method can improve the corrosion resistance of aluminum alloy, its ability to adapt to the environment is poor, the conversion film layer is not uniform, easy to fall off, and the wear resistance is not improved; and the invention patent with publication number CN104109463A discloses an aluminum alloy surface treatment agent, which can form a stable film on the surface of aluminum alloy. The film has excellent corrosion resistance and impact resistance, can improve adhesion to the workpiece surface, and has a stable protective effect.

[0003] The above-mentioned surface treatment agent usually exists in the form of bottled products in industrial production. In the final process of the surface treatment agent production process, the prepared surface treatment agent needs to be injected into the bottle through a nozzle. If the bottle fails to face the nozzle directly during the filling process, leakage will occur, resulting in waste. Therefore, an aluminum alloy surface treatment agent filling equipment is proposed.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, a base 1 of an aluminum alloy surface treatment agent filling equipment is provided, a mounting plate 2 that can be raised and lowered is provided above the base 1, a centering clamping assembly 3 is provided on the mounting plate 2 to clamp and position the bottle body, a support frame 5 is fixed on the upper end of the base 1, a storage tank 6 is fixed on the upper end of the support frame 5, a nozzle 7 is connected and fixed at the lower end of the storage tank 6, a pump is provided on the storage tank 6, and the treatment agent in the storage tank 6 can be sprayed out from the lower end of the nozzle 7 under the drive of the pump; after the bottle body is positioned and fixed by the centering clamping assembly 3, it can ensure that the bottle mouth of the bottle body is aligned with the nozzle 7 to achieve filling, and leakage caused by misalignment of the nozzle can be avoided;

[0026] It is worth mentioning that, in some embodiments, the treatment agent in the storage tank 6 can also be injected into the bottle body through the nozzle 7 by relying solely on gravity (without using a pumping method).

[0027] In this embodiment, a cylinder 4 is provided at the upper end of the base 1, and a connecting frame 41 is fixed on the driving shaft of the cylinder 4. The connecting frame 41 is fixed to the mounting plate 2. Under the drive of the cylinder 4, the mounting plate 41 is raised and lowered, so that the end of the nozzle can enter the bottle body for filling, further reducing the occurrence of leakage.

[0028] like Figure 2 As shown, the centering clamping assembly 3 includes two V-shaped clamping blocks 31 that can synchronously slide in opposite directions. The two V-shaped clamping blocks 31 are synchronously approached to achieve centering clamping of the bottle body to ensure that the bottle body is aligned with the nozzle;

[0029] In this embodiment, a connecting plate 311 is provided at the lower end of the V-shaped clamping block 31, and the connecting plate 311 is slidably matched with the mounting plate 2 and extends to the bottom of the mounting plate 2. The lower end of the mounting plate 2 is rotatably connected to a screw rod 32, and the two ends of the screw rod 32 are respectively provided with a first external thread 321 and a second external thread 322 with opposite rotation directions and equal pitches. The first external thread 321 and the second external thread 322 respectively penetrate the two connecting plates 311 and are threadedly connected thereto. By arranging a motor at the lower end of the mounting plate 2 to drive the screw rod 32 to rotate, the synchronous reverse sliding of the two V-shaped clamping blocks 31 can be achieved.

[0030] Furthermore, in order to ensure the stability of the bottle body clamping, the screw rod 32 needs to have a self-locking property, that is, the thread lead angles of the first external thread 321 and the second external thread 322 are both smaller than the equivalent friction angle.

[0031] Of course, the method of driving the two V-shaped clamps 31 to slide synchronously in opposite directions includes but is not limited to the screw rod 32 in this embodiment. In some embodiments, two cylinders can be set on the mounting plate 2 to drive the two V-shaped clamps 31 to slide synchronously in opposite directions respectively.

[0032] like Figure 3 and Figure 4 As shown, the nozzle 7 includes a shell 71 fixed to the lower end of the storage tank 6, a conical surface 711 is provided inside the shell 71, a piston 72 is provided inside the shell 71, the piston 72 is truncated, and can cooperate with the conical surface 711 to complete the blocking of the nozzle 7 to prevent filling;

[0033] A fixing rod 74 is fixed in the shell 71, and two guide rods 73 are fixed to the upper end of the piston 72. The guide rods 73 penetrate the fixing rod 74 along the vertical direction and slide with it. A spring 75 is sleeved on the guide rod 73, and the two ends of the spring 75 are fixedly connected to the fixing rod 74 and the piston 72 respectively. Under the elastic force of the spring 75, the piston 72 can cooperate with the conical surface 711 to complete the blocking of the end of the nozzle 7.

[0034] A push rod 76 is fixed at the center of the lower end of the piston 72. The push rod 76 extends out of the nozzle 7. By applying an upward lifting force to the push rod 76, the piston 72 can be moved away from the conical surface 711. At this time, the treatment agent in the storage tank 6 can be sprayed out from the nozzle 7 under the drive of the pump.

[0035] In this embodiment, a sleeve 8 is installed at the bottle mouth of the bottle body, the outer diameter of the sleeve 8 is matched with the inner diameter of the bottle mouth, and a flange 81 is provided at the upper end of the sleeve 8 to facilitate the installation of the sleeve 8 at the bottle mouth; the inner diameter of the sleeve 8 is larger than the outer diameter of the end of the nozzle 7, and as the mounting plate 2 drives the bottle body to rise, the end of the nozzle 7 can enter the sleeve 8 to prevent leakage;

[0036] The lower end of the sleeve 8 is fixed with a stopper 82. When the end of the nozzle 7 enters the sleeve 8 (also the bottle body), the push rod 76 can contact the stopper 82 and drive the piston 72 to rise. At this time, the treatment agent in the storage tank 6 can be injected into the bottle body from the nozzle 7 to complete the filling. After the filling is completed, the sleeve 8 is removed and the bottle cap is tightened.

[0037] Working principle:

[0038] By setting a lifting mounting plate 2 on the base 1, setting a centering clamping assembly 3 on the mounting plate 2, and setting two V-shaped clamping blocks 31 that can slide synchronously in opposite directions in the centering clamping assembly 3, the centering clamping of the bottle body is realized to ensure that the bottle mouth of the bottle body is aligned with the nozzle 7, so as to avoid leakage caused by the misalignment of the nozzle 7. By setting a piston 72 that can block the nozzle outlet in the nozzle 7, and setting a push rod 76 at the end of the piston 72 to cooperate with the sleeve 8 out of the bottle mouth, when the end of the nozzle 7 enters the sleeve 8, the push rod 76 can contact the stop rod 82 and drive the piston 72 to rise. At this time, the treatment agent in the storage tank 6 can be injected into the bottle body from the nozzle 7 to complete the filling, and avoid the occurrence of leakage during the filling process.
