Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a clamping fixture for aluminum profile processing. Background Technology

[0002] Aluminum profiles are widely used in construction, automotive, aerospace and other fields. In the machining process of aluminum profiles, such as cutting, drilling and milling, it is necessary to use fixtures to reliably fix them on the worktable to ensure machining accuracy and operational safety. However, aluminum profiles are softer than iron, and existing aluminum profile fixtures are mostly general-purpose flat-jaw vises or simple pressure plate structures. When clamping from the side, they may cause extrusion deformation of the aluminum profile edges, which can damage the profile. Furthermore, when dealing with aluminum profiles of different cross-sectional shapes, such as square, rectangular and L-shaped aluminum profiles or aluminum profiles of different lengths, general-purpose fixtures cannot provide stable and comprehensive clamping, which can easily lead to displacement or deformation of the profile during processing. In order to solve the above problems, the inventor proposes a clamping fixture for aluminum profile processing. Utility Model Content

[0023] Working principle: When using this utility model, the support plate 2 is used to support the aluminum profile to be processed. When placing aluminum profiles with square or rectangular cross-sections, the square or rectangular aluminum profiles can be placed directly on the support plate 2. When it is necessary to clamp aluminum profiles with L-shaped cross-sections, the L-shaped side of the aluminum profile can be inserted into the groove on the support plate 2 so that the top surface is horizontal, so that the clamping plate 10 can cooperate with the support plate 2 to clamp the aluminum profile with L-shaped cross-section.

[0025] Next, the motor 15 is started, and the worm gear 16 rotates under the action of the output shaft of the motor 15. Through the meshing of the worm gear 16 and the worm wheel 14, the horizontal shaft 12 can be rotated, which in turn causes the drive gear 13 to rotate. Through the meshing of the drive gear 13 and the first tooth plate 18, and with the cooperation of the guide column 19 and the fixed cylinder 20, as well as the cooperation of the first slide rail 21 and the cavity plate 22, the first lifting column 17 can be moved vertically smoothly. Through the rotating joint 23, the second lifting column 24 can be moved vertically. Then, through the extension rod 8, the clamping plate 10 can be lowered. The lowered clamping plate 10 cooperates with the support plate 2 to clamp the aluminum profile placed on the support plate 2.

[0026] When it is necessary to clamp aluminum profiles of different lengths, loosen the nut 7 and push the box 4 to move horizontally on the base 1 to adjust the position of the box 4 so as to clamp aluminum profiles of different lengths. After the adjustment is completed, tighten the nut 7. Through the cooperation of the nut 7 and the fastening bolt 6, the adjusted box 4 can be limited and fixed.
