Description

Technical Field

[0001] This utility model relates to the field of aluminum plate clamping technology, specifically to an aluminum plate clamping anti-deformation fixture. Background Technology

[0002] Before anodizing, aluminum sheets need to undergo processes such as cutting, punching, and drilling. Stable and reliable clamping of the aluminum sheets is crucial for ensuring processing accuracy and quality. Traditional clamping fixtures often employ simple mechanical clamping methods, relying on significant clamping force to secure the aluminum sheets.

[0003] However, aluminum sheets are relatively soft, especially thinner ones. Under strong clamping force, they are prone to deformation. For example, when drilling thin aluminum sheets, excessive clamping force can cause indentations and dents on the surface, which seriously affects the dimensional accuracy and surface quality of the aluminum sheet. This results in the aluminum sheet failing to meet the requirements of high-precision products, greatly increasing the scrap rate and production costs. Therefore, we need to propose an aluminum sheet clamping anti-deformation fixture. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum plate clamping anti-deformation fixture to solve the problem mentioned in the background art that the thin aluminum plate will deform due to excessive clamping force when clamping the aluminum plate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An aluminum plate clamping anti-deformation fixture includes: a base with a placement seat fixedly installed on its top, a push cylinder fixedly installed on both sides of the placement seat, and a push plate fixedly installed on the telescopic end of the push cylinder; a pre-clamping mechanism for flexibly pre-fixing the aluminum plate, which is installed on the push plate; and an adsorption fixing mechanism installed on the pre-clamping mechanism for fixing the pre-clamping mechanism.

[0006] Preferably, the pre-clamping mechanism includes a connecting rod, a clamping plate, and a push spring. The connecting rod is movably inserted into the push plate, the clamping plate is fixedly installed at the end of the connecting rod, the push spring is sleeved on the connecting rod, one end of the connecting rod abuts against the side of the push plate, and the other end of the connecting rod abuts against the side of the clamping plate.

[0007] A positioning rod is fixedly connected to the side of the push plate for positioning. The positioning rod is movably inserted into the inside of the placement seat, thereby guiding and positioning the push plate so that the push plate can move stably.

[0008] Preferably, the adsorption and fixing mechanism includes a mounting plate, an electromagnet, and a fixing block. The mounting plate is fixedly connected to the side of the clamping plate, the electromagnet is fixedly installed inside the mounting plate, and the fixing block is fixedly installed on the top of the placement seat.

[0009] Preferably, the bottom of the clamping plate contacts the top of the fixing block, and the bottom of the clamping plate is horizontally positioned with the bottom of the mounting plate.

[0010] Preferably, a rubber pad is fixedly installed on the side of the clamping plate, and a cleaning rubber block is fixedly installed on the side of the mounting plate.

[0011] Preferably, it also includes a support mesh plate, the top of the placement seat has an installation opening, the support mesh plate is fixedly installed in the installation opening, and the support mesh plate has multiple sets of clearance holes corresponding to the drilling positions of the aluminum plate.

[0012] Preferably, it also includes a collection box, which is placed on top of the base and inserted into the interior of the placement base.

[0013] Preferably, the top of the placement seat is provided with a discharge port for waste disposal.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention, through the design of a pre-clamping mechanism and an adsorption fixing mechanism, uses a cylinder to push a push plate, allowing the pre-clamping mechanism to flexibly pre-fix the aluminum plate when it approaches it. This avoids defects such as indentations and dents caused by excessive force in traditional rigid clamping. After pre-clamping, the adsorption fixing mechanism further stabilizes the pre-clamping state, ensuring uniform and controllable clamping force. This not only guarantees the stability of the aluminum plate during processing but also prevents deformation caused by over-clamping, reducing scrap rate, rework costs, and improving production efficiency and product qualification rate.

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: An aluminum plate clamping anti-deformation fixture includes: a base 1, on which a placement seat 2 is fixedly installed, and a push cylinder 6 is fixedly installed on both sides of the placement seat 2, and a push plate 7 is fixedly installed on the telescopic end of the push cylinder 6; a pre-clamping mechanism for flexibly pre-fixing the aluminum plate, which is installed on the push plate 7; and an adsorption fixing mechanism, which is installed on the pre-clamping mechanism for fixing the pre-clamping mechanism.

[0019] It should be noted that the push cylinder 6 is a CQ2B63-100 model push cylinder. The push cylinder 6 and the electromagnet 13 are controlled automatically by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Therefore, its specific circuit connection, control logic and working process will not be described in detail.

[0020] The pushing cylinders 6 on both sides of the placement seat 2 need to be activated simultaneously. The synchronous activation of the two sets of pushing cylinders 6 is the core control link to ensure that the aluminum plate is evenly stressed and to avoid clamping deviation. In terms of control method, a pneumatic valve group and controller linkage mode is adopted. The electromagnetic reversing valves of the two sets of cylinders are triggered simultaneously by a single control signal to ensure that the valve core action time difference is ≤5ms.

[0021] In an optional embodiment: such as Figures 2 to 4 As shown, the pre-clamping mechanism includes a connecting rod 8, a clamping plate 9, and a push spring 10. The connecting rod 8 is movably inserted into the push plate 7, the clamping plate 9 is fixedly installed at the end of the connecting rod 8, and the push spring 10 is sleeved on the connecting rod 8. One end of the connecting rod 8 abuts against the side of the push plate 7, and the other end of the connecting rod 8 abuts against the side of the clamping plate 9.

[0022] It should be noted that the connecting rod 8 serves to support and position the clamping plate 9, allowing the clamping plate 9 to be stably installed on the push plate 7. Furthermore, the push spring 10 can push the clamping plate 9. When the clamping plate 9 is close to the side of the aluminum plate and clamps it, the push plate 7 continues to push the clamping plate 9 by pushing the spring 10, so that the clamping plate 9 flexibly pre-fixes the aluminum plate and avoids defects such as indentations and dents caused by excessive clamping force. A positioning rod 18 for positioning is fixedly connected to the side of the push plate 7. The positioning rod 18 is movably inserted into the inside of the placement seat 2, thereby guiding and positioning the push plate 7 so that the push plate 7 can move stably.

[0023] In an optional embodiment: such as Figures 3 to 4 As shown, the adsorption and fixing mechanism includes a mounting plate 12, an electromagnet 13, and a fixing block 15. The mounting plate 12 is fixedly connected to the side of the clamping plate 9, the electromagnet 13 is fixedly installed inside the mounting plate 12, and the fixing block 15 is fixedly installed on the top of the placement base 2. The bottom of the clamping plate 9 contacts the top of the fixing block 15, and the bottom of the clamping plate 9 is horizontally positioned with the bottom of the mounting plate 12.

[0024] It should be noted that the fixing block 15 is made of a ferromagnetic material such as iron, cobalt, nickel, or steel. Ferromagnetic materials have extremely high magnetic permeability. In this application, the fixing block 15 is made of iron, and the electromagnet 13 is a DC24V-600N type electromagnet. After the electromagnet 13 is energized, it can be attracted and fixed on the fixing block 15, thereby fixing the clamping plate 9, stabilizing the clamping state of the clamping plate 9, ensuring uniform and controllable clamping force, ensuring the stability of aluminum plate processing, preventing deformation caused by over-clamping, reducing scrap rate, reducing rework costs, and improving production efficiency and product qualification rate.

[0025] In an optional embodiment: such as Figure 4 As shown, a rubber pad 11 is fixedly installed on the side of the clamping plate 9, and a cleaning rubber block 14 is fixedly installed on the side of the mounting plate 12.

[0026] It should be noted that the rubber pad 11 prevents the clamping plate 9 from directly contacting the aluminum plate, thus preventing damage to the aluminum plate edge. The bottom of the rubber pad 11 contacts the top of the fixing block 15, and the bottom of the cleaning rubber block 14 contacts the top of the placement seat 2. The rubber pad 11 and the cleaning rubber block 14 can clean the waste generated when drilling the aluminum plate at the top of the placement seat 2, preventing the waste from accumulating on the placement seat 2.

[0027] In an optional embodiment: such as Figures 1 to 3 As shown, it also includes a support mesh plate 4. The top of the placement seat 2 is provided with an installation opening 3. The support mesh plate 4 is fixedly installed in the installation opening 3. The support mesh plate 4 is provided with multiple sets of clearance holes 5 corresponding to the drilling positions of the aluminum plate. It also includes a collection box 17, which is placed on top of the base 1 and inserted into the interior of the placement seat 2.

[0028] It should be noted that, through the setting of the support mesh plate 4, the waste generated when drilling holes in the aluminum plate can fall into the collection box 17 for collection after passing through the support mesh plate 4.

[0029] In an optional embodiment: such as Figure 3 As shown, the top of the placement seat 2 is provided with a discharge port 16 for discharging waste.

[0030] It should be noted that after drilling holes in the aluminum plate, when the extension end of the cylinder 6 is pushed back to reset the clamping plate 9, the rubber pad 11 and the cleaning rubber block 14 can scrape and clean the waste on the top of the placement seat 2. The scraped waste can fall into the collection box 17 through the discharge port 16 and be collected.

[0031] The usage process of this utility model is as follows: Place the aluminum plate on top of the support mesh plate 4, start the push cylinder 6, push the push plate 7 with the telescopic end of the push cylinder 6, so that the push plate 7 drives the clamping plate 9 close to the aluminum plate. When the clamping plate 9 is close to the side of the aluminum plate and clamps it, the push cylinder 6 continues to push the push plate 7. The push plate 7 continues to push the clamping plate 9 through the push spring 10, so that the clamping plate 9 flexibly pre-fixes the aluminum plate and avoids defects such as indentations and dents caused by excessive clamping force. After the aluminum plate is pre-clamped, the electromagnet 13 is activated. When the electromagnet 13 is energized, it generates magnetism and attracts the electromagnet 13 to the fixing block 15, thereby fixing the clamping plate 9 on the placement seat 2. This stabilizes the clamping state of the clamping plate 9, ensures that the clamping force is uniform and controllable, guarantees the stability of the aluminum plate during processing, prevents deformation caused by over-clamping, reduces the scrap rate, reduces rework costs, and improves production efficiency and product qualification rate.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
