Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped aluminum profile machine clamps, in particular to a clamp for machining special-shaped aluminum profiles. Background Art

[0002] Special-shaped aluminum profile machines are mechanical equipment used to process aluminum alloy profiles of special shapes. The thickness and shape of these profiles may vary. When processing special-shaped aluminum profiles, they need to be fixed with a clamp to ensure the stability of the processing process.

[0003] The Chinese invention patent with the publication number CN112372527B discloses a fixing device for a special-shaped aluminum alloy profile, which includes a special-shaped aluminum profile, a lower clamp supporting the special-shaped aluminum profile, an upper clamp cooperating with the lower clamp, a fixed core arranged inside the special-shaped aluminum profile, and a driving mechanism for driving the upper clamp to rise and fall; the special-shaped aluminum profile includes an inner core, a plurality of fin groups arranged on the outer wall of the inner core, and a plurality of T-shaped structures arranged on the outer wall of the inner core. By setting the inner walls of the upper clamp and the lower clamp to a shape matching the outer shape of the special-shaped aluminum profile, the contact area between the upper clamp, the lower clamp and the special-shaped aluminum profile is increased to the maximum extent, thereby increasing the bearing capacity of the special-shaped aluminum profile, ensuring the integrity of its surface and preventing its deformation. On the other hand, by setting the fixed core, the inner core of the special-shaped aluminum profile is prevented from being deformed, and the special-shaped aluminum profile is protected in all directions to ensure its integrity.

[0004] The above-mentioned prior art directly uses adaptive upper and lower clamps to fix special-shaped aluminum profiles. The special-shaped aluminum profiles fixed by the above-mentioned prior art are specific, and can only clamp and fix aluminum profiles of this shape, but cannot flexibly fix aluminum profiles of different sizes and shapes. The flexibility during use is low. Therefore, we propose a clamp for machining special-shaped aluminum profiles to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a clamp for machining special-shaped aluminum profiles to solve the problem in the current market that aluminum profiles of different sizes and shapes cannot be flexibly fixed, as proposed by the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a fixture for machining special-shaped aluminum profiles, comprising a fixing frame, a fixing seat is installed on the upper side of the fixing frame, a fixing block is elastically connected to the inner side of the fixing seat through a first spring, a moving rod is installed on the outer side of the fixing block, and one end of the moving rod extending into the interior of the fixing seat is connected to a first magnet;

[0007] A positioning hole is provided on the rear side of the moving rod;

[0008] A rotating ring is rotatably connected inside the fixing seat, a second magnet is installed on the inner side of the rotating ring, and a protrusion is connected on the outer side of the rotating ring;

[0009] A locking mechanism for firmly clamping the special-shaped aluminum profile is arranged on the rear side of the fixing seat.

[0010] Preferably, the locking mechanism includes a support rod installed on the rear side of the fixing seat, the end of the support rod is elastically connected to a positioning frame via a second spring, a movable ring is installed at the lower end of the positioning frame, and the front side of the movable ring is connected to the positioning rod.

[0011] Preferably, the fixing blocks are distributed at equal angles with respect to a center point of the fixing seat, and the fixing seat is a circular ring structure.

[0012] Preferably, the moving rod passes through the inner wall of the fixing seat and is slidably connected to the fixing seat, and positioning holes are evenly distributed on the rear side of the moving rod.

[0013] Preferably, the position of the first magnet and the position of the second magnet are arranged in one-to-one correspondence, and the first magnet and the second magnet are magnets of the same polarity.

[0014] Preferably, the protrusion passes through the outer wall of the fixing seat and is slidably connected to the fixing seat, and the protrusion and the positioning frame are engaged with each other after their positions correspond to each other.

[0015] Preferably, the position of the positioning rod and the position of the moving rod are arranged corresponding to each other, and the positioning rod and the positioning hole are engaged with each other.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] ① The fixture for machining special-shaped aluminum profiles drives the rotating ring to rotate so that the second magnet corresponds to the first magnet, and uses the repulsive force of the magnets with the same polarity to drive the moving rod to drive the fixed block to move, so that the fixed blocks distributed at equal angles fit the surface of the special-shaped aluminum profile, and the special-shaped aluminum profile is extruded and fixed to adapt to the shape of the special-shaped aluminum profile, which is convenient for fixing special-shaped aluminum profiles of different shapes, thicknesses and sizes, and improves the flexibility of the device;

[0018] ② The fixture for machining special-shaped aluminum profiles only needs to drive the positioning frame to move, control the moving ring to drive the positioning rod to move, and turn the protrusion to drive the rotating ring to rotate, so as to fix the special-shaped aluminum profile. The operation is simple and convenient, and the elastic force of the second spring is used to make the positioning frame stuck in the protrusion and lock the rotating ring. At the same time, the positioning rod is stuck in the positioning hole opened by the moving rod, locking the moving rod and the fixing block, thereby firmly fixing the special-shaped aluminum profile and improving the convenience of using the device.
