Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a special fixture for CNC machining centers of aluminum profiles. Background Technology

[0002] Aluminum profiles are strip-shaped metal materials with specific cross-sectional shapes, made primarily of aluminum through processes such as hot-melt extrusion and surface treatment. Their core advantages lie in their lightweight, high strength, corrosion resistance, and ease of processing, making them widely used in construction, transportation, electronics, and machinery manufacturing. Aluminum profiles require clamps for fixing during processing; however, due to the varying surface shapes (flat and curved) of different profile types, fixing them can be inconvenient, and the fixing effect needs further improvement. Utility Model Content

[0003] The main purpose of this utility model is to provide a special fixture for CNC machining centers of aluminum profiles, which is designed to be adaptable to different types of aluminum profiles and has a good clamping effect.

[0004] To achieve the above objectives, this utility model proposes a special fixture for CNC machining centers of aluminum profiles, comprising:

[0005] Base;

[0006] The two side clamping structures are disposed opposite to each other on the surface of the base. Each side clamping structure has an abutment and a spring, and the spring can drive the two abutments to approach each other.

[0007] A top-side clamping structure is disposed on the surface of the base adjacent to the two side clamping structures. The top-side clamping structure includes a support frame, a rotating block, and a pressing rod. The support frame has a pressing groove, and the rotating block is rotatably disposed in the pressing groove. The rotating block has a flat surface and a curved surface facing away from each other. The pressing rod is movably connected to the top of the support frame, and the end of the pressing rod abuts against the rotating block.

[0008] In one embodiment of the present invention, the support frame includes a horizontal column and two vertical columns connected to both ends of the horizontal column, and the horizontal column and the vertical columns together form the pressure groove.

[0009] In one embodiment of this utility model, the opposing surfaces of the two columns are provided with adjustment grooves, and the two ends of the rotating block are provided with locking parts, which are movably disposed in the adjustment grooves.

[0010] In one embodiment of the present invention, the side clamping structure further includes a fixing frame disposed on the surface of the base, the abutting member passing through the fixing frame, the abutting member having a pressing piece, and the spring disposed between the pressing piece and the fixing frame.

[0011] In one embodiment of the present invention, a limiting groove is formed on the surface of the base, two side clamping structures are respectively disposed on both sides of the limiting groove, and the top clamping structure is disposed above the limiting groove.

[0012] This invention employs a side-clamping structure that uses springs to drive the abutment parts to approach each other, thereby clamping the aluminum profile on both sides. The pressure provided by the springs ensures that the aluminum profile will not move during processing. The top-level clamping structure generates downward pressure through the cooperation of a rotating block and a downward pressure rod, further enhancing the clamping force. The plane and curved surface of the rotating block can be adjusted according to the shape of the aluminum profile to ensure effective fixation of the aluminum profile by the fixture. These two clamping structures work together to stably fix the aluminum profile on the machining center, preventing movement during processing. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Reference Figures 1 to 2This utility model proposes a special fixture for CNC machining centers of aluminum profiles, including a base 1, two side clamping structures and a top clamping structure. The two side clamping structures are arranged opposite each other on the surface of the base 1. The side clamping structures have abutment members 2 and springs 3. The springs 3 can drive the two abutment members 2 to approach each other. The top clamping structure is arranged adjacent to the two side clamping structures on the surface of the base 1. The top clamping structure includes a support frame 4, a rotating block 5 and a pressing rod 6. The support frame 4 forms a pressing groove 41. The rotating block 5 is rotatably arranged in the pressing groove 41. The rotating block 5 has a flat surface 51 and a curved surface 52 arranged opposite to each other. The pressing rod 6 is movably connected to the top of the support frame 4, and the end of the pressing rod 6 abuts against the rotating block 5.

[0021] Understandably, the base 1, as the foundation of the fixture, provides support and fixation. The two side clamping structures are located on the surface of the base 1 and are symmetrically arranged on both sides. Their function is to fix the two sides of the aluminum profile and prevent the aluminum profile from shifting laterally during processing. The abutment 2 is the part that contacts the aluminum profile and is used to apply clamping force. The function of the spring 3 is to push the two abutment 2 closer together, so as to make the clamping force stronger and ensure that the fixture stabilizes the aluminum profile.

[0022] The top clamping structure is also located on the surface of the base 1, near the side clamping structures, and is used to clamp the top surface of the aluminum profile, further enhancing the fixing effect. The support frame 4 is part of the top clamping structure, used to support the rotating block 5 and the pressing rod 6 and cooperate with each other. The rotating block 5 has two surfaces, a flat surface 51 and a curved surface 52, which are used to accommodate different surfaces of the aluminum profile and provide appropriate contact surfaces. The rotating block 5 can rotate within the pressing groove 41 of the support frame 4, and its main function is to adjust the clamping force by rotating. The pressing rod 6 is connected to the top of the support frame 4, and the end of the pressing rod 6 abuts against the rotating block 5, increasing the clamping force through the pressing action.

[0023] The side clamping structure uses springs 3 to drive the abutment parts 2 to approach each other, thereby clamping the aluminum profile on both sides. The pressure provided by the springs 3 ensures that the aluminum profile will not move during processing. The top clamping structure generates downward pressure through the cooperation of the rotating block 5 and the downward pressure rod 6, further enhancing the clamping force. The plane 51 and curved surface 52 of the rotating block 5 can be rotated and adjusted according to the shape of the aluminum profile to ensure effective fixation of the aluminum profile by the fixture. The two clamping structures work together to stably fix the aluminum profile on the machining center, preventing displacement during processing.

[0024] Reference Figures 1 to 2 In one embodiment of this application, the support frame 4 includes a horizontal column 42 and two vertical columns 43 connected vertically to both ends of the horizontal column 42. The horizontal column 42 and the vertical columns 43 together form a downward pressure groove 41.

[0025] Understandably, the horizontal column 42 is located at the top of the support frame 4, providing lateral support. The vertical columns 43 are installed vertically at both ends of the horizontal column 42, supporting the horizontal column 42 and giving the support frame 4 a certain height. The vertical columns 43 provide vertical support within the overall support frame 4. The horizontal column 42 and the vertical columns 43 are interconnected to form a frame structure.

[0026] The interconnection and shape of the horizontal column 42 and the vertical column 43 together constitute the groove-shaped structure of the pressing groove 41. Specifically, the combination of the horizontal column 42 and the two vertical columns 43 creates a groove-shaped area on their inner sides, which perfectly accommodates the rotating block 5. The movement of the rotating block 5 takes place within this pressing groove 41.

[0027] Reference Figures 1 to 2 In one embodiment of this application, an adjustment groove 44 is provided on the opposite surfaces of the two columns 43, and a locking part 53 is provided at both ends of the rotating block 5, the locking part 53 being movably disposed in the adjustment groove 44.

[0028] Understandably, the purpose of the adjusting groove 44 is to allow the rotating block 5 to be adjusted in position between the columns 43 as needed, thereby precisely controlling the clamping force and clamping position. The adjusting groove 44 can help change the position or direction of the rotating block 5, further optimizing the clamping effect. The locking part 53 is a structural component extending from both ends of the rotating block 5, which can be locked in the adjusting groove 44 to prevent it from coming off.

[0029] The engagement of the locking part 53 with the adjustment groove 44 provides a stable guide for the rotating block 5 during its movement, ensuring smooth movement within the adjustment groove 44 without disengaging from its control. By adjusting the position of the locking part 53 within the adjustment groove 44, the operator can precisely control the angle and clamping force of the rotating block 5, allowing the fixture to adjust the clamping effect according to different aluminum profiles.

[0030] Reference Figure 1 In one embodiment of this application, the side clamping structure further includes a fixing frame 7 disposed on the surface of the base 1, an abutment 2 passing through the fixing frame 7, the abutment 2 having a pressing piece 21, and a spring 3 disposed between the pressing piece 21 and the fixing frame 7.

[0031] Understandably, the fixing frame 7 is mounted on the base 1 of the fixture, ensuring the robustness of the entire clamping structure. This structure effectively abuts against the aluminum profile, providing a stable clamping force. The abutment 2 is the component in the fixture that contacts the workpiece; it passes through the fixing frame 7 and can slide. The pressing plate 21 is part of the abutment 2; it directly applies pressure to the workpiece surface to ensure the workpiece is clamped, helping to fix the workpiece and prevent movement during processing. The spring 3 provides elastic force to the fixture, allowing the pressing plate 21 to adaptively adjust according to different shapes and sizes of the workpiece. This ensures that the clamping force is neither too large nor too small, avoiding excessive pressure or insufficient clamping.

[0032] Reference Figure 1 In one embodiment of this application, a limiting groove 11 is formed on the surface of the base 1, and two side clamping structures are respectively disposed on both sides of the limiting groove 11, and a top clamping structure is disposed above the limiting groove 11.

[0033] Understandably, the limiting groove 11 is a groove on the surface of the base 1. Its function is to provide a precise reference position for the positioning of the workpiece, which can ensure that the workpiece maintains an accurate fixed position during processing and avoids movement or displacement during processing. It provides a mechanical alignment method for the fixture, which is especially suitable for scenarios that require high-precision processing.

[0034] This utility model's technical solution employs a side-clamping structure where spring 3 drives the abutment parts 2 to approach each other, thereby clamping both sides of the aluminum profile. The pressure provided by spring 3 ensures that the aluminum profile will not move during processing. The top-level clamping structure generates downward pressure through the cooperation of rotating block 5 and downward pressure rod 6, further enhancing the clamping force. The plane 51 and curved surface 52 of rotating block 5 can be rotated and adjusted according to the shape of the aluminum profile, ensuring effective fixation of the aluminum profile by the fixture. These two clamping structures work together to stably fix the aluminum profile on the machining center, preventing movement during processing.
