Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, and in particular to a positioning device for aluminum processing. Background Technology

[0002] Aluminum materials are products made of aluminum and other alloying elements. The main metallic element is aluminum, and some alloying elements are added to improve the performance of aluminum materials. Aluminum materials are usually first processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc., and then made through processes such as cold bending, sawing, drilling, assembly, and coloring.

[0003] Existing positioning devices for aluminum processing are prone to causing aluminum materials to skew when fixing them, thus affecting the accuracy of aluminum processing.

The positioning mechanism includes a positioning seat fixedly connected to the top of the base, and a placement mechanism for placing the aluminum material to be processed is installed on the top of the positioning seat. In this invention, the aluminum material to be processed is placed on the placement seat, so that under the action of the aluminum material's own gravity, it can squeeze the placement seat, thereby driving the bottom abutment rod of the placement seat to squeeze the L-shaped rotating clamp rod, thus causing the L-shaped rotating clamp rod to rotate toward the aluminum material. Then, the aluminum material can be conveniently clamped by the clamping assembly. When the aluminum material is processed from the top, the pressure of the aluminum material on the placement seat will increase, thereby ensuring the stability of the aluminum material processing and thus ensuring the processing quality of the aluminum material.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing positioning devices for aluminum processing lack an automatic pushing and positioning structure for excessively long rectangular aluminum materials. This results in the need for manual pushing after a section has been cut or processed, thereby reducing the efficiency of continuous aluminum processing.

[0006] Therefore, a positioning device for aluminum processing is proposed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A positioning device for aluminum processing includes a worktable 1. A conveying mechanism 2 is welded to the top of the worktable 1. A positioning mechanism 3 is provided on the right side of the rear side of the top of the worktable 1. The conveying mechanism 2 includes a guide protrusion 21, a limiting groove 22, two limiting plates 23, a lead screw 24, a stepper motor 25, a limiting rod 26, a moving beam 27, an electric cylinder 28, and a positioning pin 29. The guide protrusion 21 is welded to the top of the worktable 1. The limiting groove 22 is provided on the right side of the top of the guide protrusion 21. The limiting plates 23 are welded to the rear side and the front side of the top of the worktable 1, respectively. The lead screw 24 is rotatably connected to the right side of the inner side of the rear limiting plate 23. The left side of the lead screw 24 is connected to a connecting shaft via a flat key. The stepper motor 25 is installed on the inner side of the rear limiting plate 23. The output end of the stepper motor 25 on the right side passes through the limiting plate 23 and is fixedly connected to the left side of the connecting shaft.

[0028] In this embodiment: The workbench 1 provides a stable mounting platform for the conveying mechanism 2 and the positioning mechanism 3. The guide protrusion 21 provides initial support and guidance for the aluminum material, preventing tilting during placement and ensuring smooth subsequent conveying and positioning. The limiting groove 22 limits the positioning pin 29 as it descends through the preset hole in the aluminum material, driven by the electric cylinder 28. The limiting plate 23 provides mounting support points for the lead screw 24, the limiting rod 26, the electric telescopic rod 35, and the stepper motor 25. The lead screw 24 rotates under the drive of the stepper motor 25, converting rotational motion into linear motion of the moving beam 27. The stepper motor 25 controls the rotation angle of the lead screw 24, thereby controlling... The moving beam 27's movement distance ensures the aluminum material is conveyed to the designated position. The limiting rod 26 is slidably connected to the front bottom of the moving beam 27, guiding and limiting the movement of the moving beam 27 and preventing it from rotating or shifting under the drive of the lead screw 24. The rear bottom of the moving beam 27 is threadedly connected to the lead screw 24, and the front bottom is slidably connected to the limiting rod 26. Under the drive of the lead screw 24, the electric cylinder 28 and the positioning pin 29 are moved. The electric cylinder 28 can drive the positioning pin 29 to move up and down, realizing the pressing and releasing action of the positioning pin 29 on the aluminum material. The positioning pin 29 can be inserted into the preset hole of the aluminum material, driving the aluminum material to move, while preventing the aluminum material from shifting during processing.

[0029] Specifically, such as Figure 2 , Figure 3 As shown, the limiting rod 26 is welded to the right side of the inner side of the front limiting plate 23, the front side of the bottom of the moving beam 27 is slidably connected to the surface of the limiting rod 26, the rear side of the bottom of the moving beam 27 is threadedly connected to the surface of the lead screw 24, the electric cylinder 28 is installed on the top of the inner side of the moving beam 27, and the positioning pin 29 is fixedly connected to the output end of the bottom of the electric cylinder 28.

[0030] Specifically, such as Figure 4 , Figure 5 As shown, the positioning mechanism 3 includes a mounting slot 31, a grating ruler 32, a mounting rod 33, a photoelectric sensor 34, an electric telescopic rod 35, an auxiliary telescopic rod 36, a clamping plate 37, and a PLC controller 38. The mounting slot 31 is located on the right side of the rear top of the workbench 1.

[0031] Specifically, such as Figure 4 , Figure 5 As shown, the grating ruler 32 is installed inside the mounting groove 31, the mounting rod 33 is welded to the rear side of the top of the moving beam 27, the photoelectric sensor 34 is installed to the rear side of the bottom of the mounting rod 33, the electric telescopic rod 35 is installed on the right side of the front side of the rear limiting plate 23 and the right side of the rear side of the front limiting plate 23 respectively, and the clamping plate 37 is welded to the telescopic end of the electric telescopic rod 35.

[0032] In this embodiment: The mounting slot 31 provides mounting space for the grating ruler 32, which can detect the moving distance of the moving beam 27 in real time, providing a position feedback signal to the PLC controller 38. This allows the controller to adjust the stepper motor 25's movement promptly, ensuring the accuracy of the aluminum material conveying distance. The mounting rod 33 provides mounting support for the photoelectric sensor 34, enabling it to move synchronously with the moving beam 27. This ensures the photoelectric sensor 34 can always accurately detect the signal from the grating ruler 32. The photoelectric sensor 34 can transmit the optical signal from the grating ruler 32... The signal is converted into an electrical signal and transmitted to the PLC controller 38 to realize real-time detection of the aluminum material's movement distance. The electric telescopic rod 35 can drive the clamping plate 37 to clamp and release the aluminum material. The auxiliary telescopic rod 36 can enhance the stability of the clamping plate 37 during the clamping process. The clamping plate 37 clamps the aluminum material under the drive of the electric telescopic rod 35. The PLC controller 38 can receive the signal from the photoelectric sensor 34 and control the stepper motor 25, electric cylinder 28, electric telescopic rod 35 and other components to work together according to the preset program to realize the automated conveying, positioning and clamping operation of the aluminum material.

[0033] Specifically, such as Figure 4 , Figure 5 As shown, the telescopic ends of the auxiliary telescopic rod 36 are installed on both sides of the clamping plate 37, and the side of the auxiliary telescopic rod 36 away from the clamping plate 37 is installed on the surface of the limiting plate 23. The PLC controller 38 is installed on the left side of the front side of the workbench 1.

[0034] Specifically, such as Figure 3 As shown, the locating pin 29 is movably connected to a lower pressure pad 4, which is made of rubber material.

[0035] In this embodiment: by setting the lower pressure pad 4, it plays a buffering role when the positioning pin 29 presses the aluminum material. By setting the lower pressure pad 4 to be made of rubber material, it avoids the positioning pin 29 from rigidly contacting the aluminum material, which would cause scratches or deformation on the surface of the aluminum material, thus protecting the surface quality of the aluminum material. At the same time, the rubber material has a certain friction, which can enhance the stability of positioning.

[0036] Specifically, such as Figure 1 As shown, the contact surface of the clamping plate 37 is fitted with a buffer pad 5, which is made of silicone material and has anti-slip textures engraved on its surface.

[0037] Specifically, such as Figure 4 As shown, a transparent dust cover 6 is installed on the top of the grating ruler 32, and the surface of the transparent dust cover 6 is coated with anti-fog paint.

[0038] In this embodiment: By setting a buffer pad 5, damage to the surface of the aluminum material can be reduced when the clamping plate 37 clamps the aluminum material. By setting the buffer pad 5 to be made of silicone material, its softness can form a buffer when the clamping plate 37 clamps the aluminum material, avoiding rigid contact. By setting anti-slip texture, the friction between the buffer pad and the aluminum material is increased, preventing the aluminum material from sliding during processing. By setting a transparent dustproof cover 6, the transparency does not affect the detection of the scale of the grating ruler 32 by the photoelectric sensor 34, ensuring the accuracy of displacement measurement. It can also prevent aluminum chips, dust and other impurities generated during processing from contaminating the surface of the grating ruler 32, avoiding the obstruction or wear of the scale lines, and extending the service life of the grating ruler 32. By setting an anti-fog coating, moisture in the environment can be prevented from condensing into fog on the surface of the cover plate, ensuring that the transmission of optical signals is not hindered. Especially in a humid workshop environment, it can maintain the detection accuracy of the photoelectric sensor 34.

[0039] Working Principle: First, the operator places the square aluminum material on the guide protrusion 21 of the workbench 1, allowing the aluminum material to move along the guide protrusion 21 to the right side of the workbench 1. Next, the operator inputs the data according to the preset processing length parameters into the PLC controller 38. The PLC controller 38 controls the electric cylinder 28 to drive the positioning pin 29 downward, allowing it to pass through the preset hole in the aluminum material and move to the inside of the limiting groove 22. Then, the PLC controller 38 starts the stepper motor 25, which drives the lead screw 24 to rotate through the connecting shaft. Since the bottom rear side of the moving beam 27 is threadedly connected to the lead screw 24 and the front side is slidably connected to the limiting rod 26, the rotational motion of the lead screw 24 is converted into the linear motion of the moving beam 27, causing the electric cylinder 28 and the positioning pin 29 mounted on the moving beam 27 to move synchronously. When the positioning pin 29 moves, it synchronously drives the aluminum material to move. At the same time, the photoelectric sensor 34 moves synchronously, reading the scale information of the grating ruler 32 in real time and transmitting the displacement signal to the PLC controller 38. Then, based on the position signal fed back by the grating ruler 32, the PLC controller 38 controls the stepper motor 25 to continue driving the moving beam 27, moving the aluminum material along the limiting groove 22 towards the right side of the worktable 1. When the aluminum material reaches the preset processing position, the PLC controller 38 controls the stepper motor 25 to stop working and starts the electric telescopic rod 35. The electric telescopic rod 35 pushes the clamping plate 37 closer to the aluminum material, and the clamping plate 37 fits against the side of the aluminum material. The auxiliary telescopic rod 36 enhances the clamping stability, realizing the final positioning of the aluminum material. Finally, the operator processes the positioned aluminum material through the processing equipment, such as drilling and cutting. When the processing is completed, the electric telescopic rod 35 drives the clamping plate 37 to reset, the electric cylinder 28 drives the positioning pin 29 to rise and disengage from the aluminum material, and the stepper motor 25 rotates in the reverse direction to drive the moving beam 27 to reset. When the reset is completed, the PLC controller 38 controls the electric cylinder 28 again to drive the positioning pin 29 to descend, passing through the preset hole to reposition the unprocessed aluminum material, thereby realizing the automated conveying, positioning and processing cycle of square aluminum materials.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
