Limiting mechanism for cutting aluminum plate

Abstract

This utility model discloses a limiting mechanism for cutting aluminum plates, specifically relating to the field of plate processing positioning technology. It includes a base on which a positioning and cutting assembly is mounted. This assembly is used to position and cut the aluminum plate. The positioning and cutting assembly includes a first clamping plate mounted on the base, with a second clamping plate disposed at one end of the first clamping plate. The first and second clamping plates work together to clamp and position the aluminum plate. This utility model, through the cooperative sliding clamping of the first and second clamping plates, combined with the anti-slip pads made of rubber on the inner side of the clamping plates, can significantly increase the friction between the clamping plates and the aluminum plate.

Description

Technical Field

[0001] This utility model relates to the field of plate processing and positioning technology, and more specifically, to a limiting mechanism for aluminum plate cutting. Background Technology

[0002] Aluminum sheets, being in the form of "sheet material or profile," cannot directly meet the industrial demand for "parts of specific shapes, sizes, and precision." The essence of cutting is to transform aluminum sheets from "raw material form" into "functional part form." Many aluminum parts used in industry (such as electronic device housings, automotive parts, mechanical supports, heat sinks, etc.) are non-standard shapes, requiring the removal of excess material through cutting. For example, the mobile phone frame needs "grooves, holes, and chamfered corners," which requires milling (a cutting method) to remove the excess part of the aluminum plate; another example is the "comb-like structure" of the heat sink, which requires cutting to process a flat aluminum plate into uniform gaps to increase the heat dissipation area; During the aluminum plate cutting process, cutting tools such as milling cutters and turning tools will apply "cutting force" (lateral thrust or longitudinal tension) to the aluminum plate. If the aluminum plate is not fixed or limited, "displacement, vibration and deformation" will occur, which will directly lead to processing failure. Therefore, a limiting mechanism for aluminum plate cutting is provided. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a limiting mechanism for cutting aluminum plates, which aims to solve the problems mentioned in the background art.

[0004] This utility model provides the following technical solution: a limiting mechanism for cutting aluminum plates, including a base, on which a positioning and cutting component is disposed, the positioning and cutting component being used to realize the positioning and cutting operation of the aluminum plate; The positioning and cutting assembly includes a first clamping plate mounted on a base, with a second clamping plate disposed at one end of the first clamping plate. The first and second clamping plates work together to clamp and position the aluminum plate. A cutter is mounted on the end of the first clamping plate facing the second clamping plate, and the cutter has a beveled edge machined on it to improve the cutting efficiency and quality of the aluminum plate. A baffle is provided on the end of the second clamping plate facing the cutter, which can limit and block the aluminum plate to prevent excessive displacement during the cutting process. One end of the base is connected to a deflection block, and a first connecting rod is hinged to the deflection block. A second connecting rod is provided on one side of the first connecting rod, and the second connecting rod is hinged to the deflection block. The deflection block can drive the first connecting rod and the second connecting rod to move through its own deflection.

[0005] Optionally, in a possible implementation, the end of the first connecting rod away from the deflection block extends to the second clamping plate and forms a linkage with the second clamping plate to drive the second clamping plate to perform corresponding actions; the end of the second connecting rod away from the deflection block extends to the beveled edge and forms a linkage with the beveled edge to adjust the position and angle of the beveled edge; a first sliding rod is hinged to the end of the first connecting rod near the second clamping plate, the first sliding rod is inserted into a preset first sliding hole on the second clamping plate, and the first sliding rod can slide in the first sliding hole; a second sliding rod is hinged to the end of the second connecting rod near the beveled edge, the second sliding rod is inserted into a preset second sliding hole on the beveled edge, and the second sliding rod can slide in the second sliding hole. Through the cooperation of the sliding rod and the sliding hole, the motion transmission between the connecting rod and the corresponding component is realized. Optionally, in a possible implementation, a connecting block is provided on one side of the deflection block, and a third connecting rod is hinged to both the connecting block and the deflection block. The third connecting rod is used to realize the motion transmission and linkage between the connecting block and the deflection block. A slider is installed at the bottom of both the first clamping plate and the second clamping plate, and a slide rail adapted to the slider is provided on the base. The first clamping plate and the second clamping plate are slidably connected to the slide rail of the base through the slider, so that the first clamping plate and the second clamping plate can slide stably along the base. A motor is fixedly installed at one end of the base, and the output shaft of the motor is connected to the connecting block for driving the connecting block to rotate. An electric push rod is provided on one side of the motor. The electric push rod is used to provide linear driving force. The output end of the electric push rod is rotatably connected to a locking pin through a bearing. The locking pin extends into a pre-set locking groove in the middle of the deflection block, and the locking pin and the locking groove are clearance fit. The electric push rod can push the deflection block to move up and down through the locking pin. Anti-slip pads are pasted on the side of the first clamping plate and the second clamping plate facing the aluminum plate. The anti-slip pads are made of rubber material and the surface of the anti-slip pads is processed with anti-slip texture. The technical effects and advantages of this utility model are as follows: The coordinated sliding clamping of the first and second clamping plates, along with the anti-slip pads made of rubber on the inner side of the clamping plates, significantly increases the friction between the clamping plates and the aluminum plate. This effectively prevents the aluminum plate from sliding under the lateral thrust and longitudinal tension of the cutting force, while also preventing direct contact between the clamping plates and the aluminum plate from scratching the surface, thus balancing positioning stability and surface quality. The baffle on the second clamping plate can directly abut against the end of the aluminum plate, forming an axial limit. During the cutting process, it can prevent excessive axial movement of the aluminum plate caused by the impact of cutting force. It is especially suitable for machining parts with high dimensional accuracy requirements, such as mobile phone frames and heat sinks, ensuring accurate cutting position and reducing the reduction of machining quality due to dimensional deviations.

[0012] 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.

[0013] This embodiment discloses a limiting mechanism for aluminum plate cutting, which aims to solve the problem in the prior art that the lack of effective limiting and fixing during the aluminum plate cutting process leads to displacement, vibration, and deformation of the aluminum plate, resulting in processing failure.

[0014] Specifically, as shown in the attached document Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4As shown, the limiting mechanism for aluminum plate cutting includes a base 1, which is made of high-strength alloy steel. Each of the four corners of the base is equipped with a shock-absorbing support foot, which is made of elastic rubber. This foot can effectively absorb the vibration generated during the operation of the mechanism, prevent the vibration from being transmitted to the aluminum plate and affecting the cutting accuracy, and ensure the overall stability of the mechanism during operation.

[0015] A positioning and cutting assembly is mounted on the base 1. This assembly is the core component for positioning and cutting the aluminum plate. The positioning and cutting assembly includes a first clamping plate 2 and a second clamping plate 3 mounted on the base 1. The first clamping plate 2 and the second clamping plate 3 are positioned opposite each other and have the same structural dimensions. A slider 15 is welded to the bottom of both the first clamping plate 2 and the second clamping plate 3. A slide rail adapted to the slider 15 is provided on the base 1, extending along the length of the base 1. The first clamping plate 2 and the second clamping plate 3 can slide smoothly along the length of the base 1 through the sliding engagement of the slider 15 and the slide rail, allowing adjustment of the distance between the two clamping plates according to the size of the aluminum plate. Furthermore, anti-slip pads are attached to the side of the first clamping plate 2 and the second clamping plate 3 facing the aluminum plate. The anti-slip pads are made of rubber and have a diamond-shaped anti-slip texture on the surface. When clamping the aluminum plate, these pads increase the friction between the clamping plates and the aluminum plate, preventing the aluminum plate from sliding during cutting, and also prevent the clamping plates from directly contacting the aluminum plate and causing scratches on the surface, thus ensuring the surface quality of the processed aluminum plate.

[0016] A cutter 4 is bolted to the end of the first clamping plate 2 facing the second clamping plate 3. The cutter 4 is made of high-speed steel, which has high hardness and wear resistance, meeting the requirements of long-term cutting of aluminum plates. A beveled edge 5 is machined on the cutter 4, forming a 30° angle with the blade body. This inclined design reduces the contact area between the cutter 4 and the aluminum plate during cutting, lowering cutting resistance. Simultaneously, it allows aluminum chips generated during cutting to be smoothly discharged along the inclined direction of the beveled edge 5, preventing chip accumulation in the cutting area and affecting the cutting effect.

[0017] A baffle 6 is fixed to the end of the second clamping plate 3 facing the cutter 4 by welding. The baffle 6 is a rectangular metal plate with the same height as the second clamping plate 3. When the aluminum plate is placed between the first clamping plate 2 and the second clamping plate 3, the baffle 6 can abut against one end of the aluminum plate, which can axially limit the aluminum plate and prevent the aluminum plate from displacing excessively under the action of cutting force.

[0018] One end of the base 1 is connected to a deflector block 7 via a bearing seat. A first connecting rod 8 and a second connecting rod 9 are hinged to the side wall of the deflector block 7. The end of the first connecting rod 8 furthest from the deflector block 7 is hinged to a first sliding rod via a pin. A first sliding hole, matching the first sliding rod, is formed on the side wall of the second clamping plate 3. The first sliding rod is inserted into the first sliding hole and can slide along the length of the hole. Similarly, the end of the second connecting rod 9 furthest from the deflector block 7 is hinged to a second sliding rod via a pin. A second sliding hole, matching the second sliding rod, is formed on the side wall of the cutter 4. The second sliding rod is inserted into the second sliding hole and can slide along the length of the hole. This combination of sliding rod and sliding hole allows the deflection motion of the deflector block 7 to be converted into the pushing and pulling motion of the first connecting rod 8 and the second connecting rod 9, thereby driving the second clamping plate 3 to slide and adjusting the position and angle of the oblique cutting edge 5.

[0019] A connecting block 10 is provided on one side of the deflection block 7. Both the connecting block 10 and the deflection block 7 are hinged to a third connecting rod 11 via a pin. The two ends of the third connecting rod 11 are rotatably connected to the connecting block 10 and the deflection block 7 respectively, enabling motion transmission between them. A motor 14 is fixedly mounted on one end of the base 1 via a motor bracket. The motor 14 is a servo motor, characterized by stable speed and high control precision. The output shaft of the motor 14 is connected to the central shaft of the connecting block 10 via a coupling. When the motor 14 starts, it drives the connecting block 10 to rotate around its own axis. During the rotation of the connecting block 10, the deflection block 7 is synchronously deflected via the third connecting rod 11.

[0020] An electric push rod 13 is fixedly mounted on one side of the motor 14 via a push rod bracket. The output end of the electric push rod 13 is rotatably connected to a locking pin 12 via a bearing. The locking pin 12 has a cylindrical structure, and a slot adapted to the locking pin 12 is opened in the middle of the deflection block 7. The locking pin 12 extends into the slot, and there is a clearance fit between the locking pin 12 and the slot to ensure that the locking pin 12 can rotate flexibly within the slot. When the electric push rod 13 extends or retracts, it can push the deflection block 7 to deflect through the locking pin 12, working in conjunction with the motor 14 to achieve precise control of the deflection angle of the deflection block 7.

[0021] The specific working principle is as follows: Before cutting the aluminum plate, the motor 14 is started according to the size of the aluminum plate to be processed. The motor 14 drives the connecting block 10 to rotate. The connecting block 10 drives the deflection block 7 to deflect through the third connecting rod 11. During the deflection of the deflection block 7, the first connecting rod 8 pushes the second clamping plate 3 to slide along the slide rail of the base 1 under the action of the deflection block 7, adjusting the distance between the first clamping plate 2 and the second clamping plate 3 to match the width of the aluminum plate. Then, the aluminum plate to be processed is placed between the first clamping plate 2 and the second clamping plate 3, with one end of the aluminum plate abutting against the baffle 6 on the second clamping plate 3, completing the initial positioning of the aluminum plate.

[0022] Next, the motor 14 is restarted, and the extension and retraction of the electric push rod 13 are coordinated to further fine-tune the deflection angle of the deflection block 7. On one hand, the first connecting rod 8 continues to push the second clamping plate 3 towards the first clamping plate 2 until the anti-slip pads on the first clamping plate 2 and the second clamping plate 3 are in close contact with the aluminum plate, thus achieving a firm clamping of the aluminum plate; on the other hand, the second connecting rod 9, driven by the deflection block 7, pushes the second sliding rod to slide in the second sliding hole of the bevel cutting blade 5, adjusting the angle and position of the bevel cutting blade 5 so that the bevel cutting blade 5 is aligned with the part of the aluminum plate that needs to be cut.

[0023] The beveled cutting edge 5 on the cutter 4 performs cutting operations on the aluminum plate. During the cutting process, the clamping force of the first clamping plate 2 and the second clamping plate 3, as well as the limiting effect of the baffle 6, can effectively prevent the aluminum plate from shifting, vibrating, and deforming; at the same time, the inclined structure of the beveled cutting edge 5 facilitates the discharge of aluminum chips, ensuring the smooth progress of the cutting process and improving the cutting accuracy and processing quality of the aluminum plate.

[0024] 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, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
