Description

Technical Field

[0001] This utility model relates to an anodizing fixture, specifically, to an anodizing fixture for sheet metal. Background Technology

[0002] To overcome the defects of metals and alloys in terms of surface hardness and wear resistance, expand their application range, and extend their service life, surface treatment technology has become an indispensable part of aluminum alloy applications. Anodizing technology is the most widely used and successful. Anodizing is the electrochemical oxidation of metals or alloys. Under appropriate electrolyte and specific process conditions, an oxide film is formed on aluminum products under the action of an applied current. To facilitate the oxidation treatment of objects, they are usually fixed by an oxidation fixture. When plate 4 needs to be treated, due to its large area, in order to improve the stability of plate 4 during the oxidation process, the contact area between the clamping parts on the oxidation fixture and plate 4 is large to improve the clamping effect. As a result, during the oxidation treatment of plate 4, the areas on the surface of plate 4 that are blocked by the clamping parts cannot be oxidized. This results in areas of plate 4 that are not oxidized, thus causing the oxidation effect of plate 4 to not meet expectations. In view of this, we propose an anodizing fixture for plate 4. Utility Model Content

[0003] The purpose of this utility model is to provide an anodizing fixture for sheet metal to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, one objective of this utility model is to provide an anodizing fixture for sheet metal, comprising a mounting shell, an mounting mechanism on the outer side of the mounting shell for clamping and fixing the sheet metal, and four mounting tubes symmetrically fixed on the outer wall of the mounting shell. A movable rod is slidably disposed inside each mounting tube, with one end of the movable rod away from the mounting shell extending to the outer side of the mounting tube. Each movable rod has two mounting brackets hinged to its end away from the mounting shell via a torsion spring. The torsion spring drives the two mounting brackets to move closer together, causing them to rotate towards the sheet metal. A mounting roller is rotatably connected to the end of each mounting bracket away from the torsion spring. When the two mounting brackets approach the sheet metal, the mounting roller contacts the side wall of the sheet metal. A driving mechanism is provided inside the mounting shell to drive the movable rods to extend and retract.

[0005] As a further improvement to this technical solution, the mounting shell has an internal mounting cavity that is connected to the interior of the mounting tube. The driving mechanism includes a rotating rod rotatably connected inside the mounting cavity. A winding reel is coaxially fixed on the rotating rod. Several connecting ropes corresponding to the number of mounting tubes are wound on the winding reel. The end of the connecting rope away from the winding reel extends into the interior of the mounting tube and is fixedly mounted at the end of the movable rod located inside the mounting tube.

[0006] As a further improvement to this technical solution, the driving mechanism also includes a compression spring disposed inside the mounting tube. The two ends of the compression spring are respectively in contact with one end of the movable rod inserted inside the mounting tube and the end of the mounting tube near the mounting shell. When the compression spring in the compressed state relaxes, it drives the movable rod to move away from the mounting tube along the axial direction of the mounting tube.

[0007] As a further improvement to this technical solution, a motor is fixedly installed on the side surface of the mounting shell away from the plate. The end of the rotating rod near the motor extends to the outside of the mounting shell. The output shaft of the motor is coaxially connected to the rotating rod through a coupling. The rotating output shaft of the motor drives the rotating rod to rotate.

[0008] As a further improvement to this technical solution, the circumferential surface of the mounting roller is provided with an inner groove. When the mounting roller contacts the side wall of the plate, the side wall of the plate is located inside the inner groove, and the protrusion of the mounting roller blocks the plate.

[0009] As a further improvement to this technical solution, an electric telescopic rod is fixedly provided on the upper surface of the mounting shell, and a mounting plate is fixedly provided on the piston end of the electric telescopic rod. When the piston end of the electric telescopic rod moves, it drives the mounting shell to move.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The board is placed between several mounting rollers using an anodizing fixture. The movable rod retracts, causing the mounting rollers to move towards the board, making them contact the side wall of the board. This clamps and fixes the four corners of the board. The mounting rollers are circular, and the contact area between the circumference of the mounting roller and the side wall of the board is small, allowing for oxidation of a larger area of ​​the board, thus effectively improving the oxidation effect. As the board oxidizes, the drive mechanism continues to retract, causing the movable rod to roll along the side wall of the board, changing the contact position between the mounting roller and the side wall of the board, and oxidizing the areas where the board previously contacted the mounting roller.

[0022] 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.

[0023] Example 1

[0024] Please see Figures 1-5 As shown, one of the objectives of this embodiment is to provide an anodizing fixture for sheet metal, including a mounting shell 1. An electric telescopic rod 11 is fixedly mounted on the upper surface of the mounting shell 1. A mounting plate is fixedly mounted on the piston end of the electric telescopic rod 11. The mounting plate is mounted on an anodizing treatment device for suspending the fixture. When the piston end of the electric telescopic rod 11 moves, it drives the mounting shell 1 to move. The mounting shell 1 is mounted on the anodizing treatment device through the mounting plate and the electric telescopic rod 11. When the electric telescopic rod 11 is working, it drives the mounting shell 1 to rise and fall through the piston end, thereby driving the sheet metal 4 to rise and fall through the electric telescopic rod 11, moving the sheet metal 4 into the anodizing processing device for anodizing processing. It also facilitates the removal of the anodized sheet metal 4 from the anodizing processing device.

[0025] An installation mechanism 2 is provided on the outside of the mounting shell 1. The installation mechanism 2 clamps and fixes the plate 4. The installation mechanism 2 includes four installation tubes 21 symmetrically fixed on the outer wall of the mounting shell 1. A movable rod 22 is slidably arranged inside the installation tube 21. The end of the movable rod 22 away from the mounting shell 1 extends to the outside of the installation tube 21. The end of each movable rod 22 away from the mounting shell 1 is hinged to two mounting brackets 23 by a torsion spring. The torsion spring drives the two mounting brackets 23 to move closer to each other, so that the mounting brackets 23 rotate towards the plate 4. The end of the mounting bracket 23 away from the torsion spring is rotatably connected to the mounting roller 24. When the plate 4 needs to be oxidized, the plate 4 is placed between several mounting rollers 24.

[0026] When the movable rod 22 needs to move towards the clamping plate 4 closer to the mounting shell 1, a drive mechanism 3 is provided inside the mounting shell 1. The drive mechanism 3 is used to drive the movable rod 22 to extend and retract. The mounting shell 1 has a mounting cavity inside, which is connected to the inside of the mounting tube 21. The drive mechanism 3 includes a rotating rod rotatably connected inside the mounting cavity. A take-up reel 31 is coaxially fixed on the rotating rod. Several connecting ropes 32 corresponding to the number of mounting tubes 21 are wound on the take-up reel 31. The end of the connecting rope 32 away from the take-up reel 31 extends into the inside of the mounting tube 21 and is fixedly installed. The movable rod 22 is located at one end inside the mounting tube 21. A motor 34 is fixedly installed on the surface of the mounting shell 1 away from the plate 4. The end of the rotating rod near the motor 34 extends to the outside of the mounting shell 1. The output shaft of the motor 34 is coaxially connected to the rotating rod through a coupling. The rotating output shaft of the motor 34 drives the rotating rod to rotate. When the motor 34 is working, the rotating output shaft of the motor 34 drives the rotating rod and the winding reel 31 to rotate and wind up the connecting rope 32. At this time, the winding of the connecting rope 32 drives the movable rod 22 to move along the axis of the mounting tube 21 towards the mounting shell 1.

[0027] The drive mechanism 3 controls the movable rod 22, causing it to move inward along the axis of the mounting tube 21. At this time, each corner of the plate 4 is positioned between two adjacent mounting rollers 24. The moving movable rod 22 drives the mounting bracket 23 and the mounting rollers 24 towards the plate 4. During the movement of the mounting rollers 24, they contact the sidewall of the plate 4, causing them to approach and press against the plate 4. As the movable rod 22 continues to move inward into the mounting tube 21, the mounting rollers 24 roll along the sidewall of the plate 4, pushing the mounting brackets 23 and increasing the angle between the two mounting brackets 23. During this process of increasing the angle between the two mounting brackets 23... The torsion spring drives the two mounting brackets 23 and the mounting rollers 24 to press the plate 4, so that the mounting rollers 24 clamp and fix the plate 4, thereby fixing the position of the plate 4. At the same time, the pressing and clamping of the plate 4 by several mounting rollers 24 increases the stability of the plate 4 in the subsequent oxidation process. As the plate 4 is oxidized, the movable rod 22 continues to move inside the mounting tube 21 towards the mounting shell 1, driving the mounting rollers 24 to roll on the side wall of the plate 4, exposing the position where the mounting rollers 24 previously contacted the plate 4. The oxidation treatment equipment then oxidizes the unoxidized parts of the plate 4, thereby greatly improving the oxidation treatment effect of the plate 4.

[0028] As the movable rod 22 moves into the mounting tube 21, to ensure the stability of its movement, the drive mechanism 3 also includes a compression spring 33 located inside the movable slot. The two ends of the compression spring 33 contact one end of the movable rod 22 inserted into the mounting tube 21 and the end of the mounting tube 21 near the mounting housing 1, respectively. When the compression spring 33 is in a compressed state and then relaxes, it drives the movable rod 22 to move away from the mounting tube 21 along its axial direction. As the movable rod 22 moves into the mounting tube 21, the compression spring 33 is compressed and contracted. When the oxidized plate 4 needs to be removed, the motor... The 34 working mechanism drives the rotating rod and the take-up reel 31 to rotate in opposite directions to unwind the connecting rope 32. At this time, the compression spring 33, which is in a compressed state, relaxes and drives the movable rod 22 to move away from the mounting tube 21 along the axis of the mounting tube 21. At this time, the torsion spring drives the two mounting brackets 23 to move closer to each other. When the mounting roller 24 and the plate 4 are about to separate, the worker picks up the plate 4, and then the mounting roller 24 continues to move away from the plate 4, so that the mounting roller 24 separates from the plate 4 to release the clamping and fixing of the mounting roller 24 on the plate 4, thereby facilitating the worker to replace the oxidized plate 4.

[0029] If the plate 4 or the mounting roller 24 shifts during the rolling process of the mounting roller 24 along the side wall of the plate 4, causing the plate 4 to detach from the mounting roller 24 and fall off, it will affect the subsequent processing of the plate 4. To prevent the plate 4 from detaching from the mounting roller 24, an inner groove is formed on the circumferential surface of the mounting roller 24. The side wall of the plate 4 is located inside the inner groove, and the surface of the inner groove is in close contact with the side wall of the plate 4. The protrusion of the mounting roller 24 blocks the plate 4, preventing the plate 4 from detaching from the mounting roller 24. During the rolling process of the mounting roller 24 along the side wall of the plate 4, the side wall of the plate 4 is located inside the inner groove of the mounting roller 24. The protrusion of the mounting roller 24 blocks the plate 4 from shifting during the rolling process, thereby preventing the plate 4 from detaching from the mounting roller 24 and improving the clamping effect of the mounting roller 24 on the plate 4.

[0030] In summary, the working principle of this scheme is as follows: The mounting shell 1 is installed on the oxidation treatment equipment via the mounting plate and the electric telescopic rod 11. The plate 4 is placed between several mounting rollers 24. The motor 34 drives the rotating rod and the winding reel 31 to rotate and wind up the connecting rope 32. The winding of the connecting rope 32 drives the movable rod 22 to move along the axis of the mounting tube 21 towards the mounting shell 1, thereby bringing the mounting rollers 24 closer to and squeezing the plate 4. At this time, the side wall of the plate 4 is located inside the inner groove of the mounting roller 24. The mounting rollers 24 squeeze the plate 4 to clamp and fix it. After the plate 4 is installed, the electric telescopic rod 11 drives the mounting shell 1 and the plate 4 to descend. The electric telescopic rod 11 moves the plate 4 into the oxidation treatment equipment for oxidation treatment. As the plate 4 is oxidized, the movable rod 22 continues to move along the mounting shell 1. The tube 21 moves towards the mounting shell 1, causing the mounting roller 24 to roll on the side wall of the plate 4, exposing the position where the mounting roller 24 previously contacted the plate 4. The un-oxidized position of the plate 4 is then oxidized by the oxidation treatment equipment, thereby significantly improving the oxidation treatment effect of the plate 4. After the oxidation treatment of the plate 4 is completed, the electric telescopic rod 11 operates to lift the plate 4 and remove it from the oxidation treatment equipment. The motor 34 operates to drive the rotating rod and the winding reel 31 to rotate in the opposite direction to unwind the connecting rope 32. The compression spring 33, which is in a compressed state, relaxes and causes the movable rod 22 to move away from the mounting tube 21 along the axis of the mounting tube 21, thereby causing the mounting roller 24 to move away from the plate 4, separating the mounting roller 24 from the plate 4, making it easier for the staff to replace the oxidized plate 4.
