Description

Technical Field

[0001] This utility model belongs to the field of fixed clamping technology, and more specifically, it relates to clamps for aluminum profile processing. Background Technology

[0002] Aluminum, as a metallic material with aluminum as the main metallic element and other alloying elements added, can significantly improve its comprehensive properties such as strength, hardness, and corrosion resistance through the reasonable ratio of alloying elements. In practical applications, aluminum profiles need to undergo a series of precision processing steps such as cutting, milling, and drilling before they can be transformed into building materials or metal parts that meet the needs of the construction and machinery manufacturing fields. When processing aluminum, it is necessary to use clamps to hold and fix the aluminum to better complete the processing of aluminum profiles.

[0003] Based on existing technology, it has been found that existing fixtures for aluminum profile processing have some shortcomings: First, the existing clamping structure design is relatively simple and is mostly suitable for fixing regular-shaped aluminum profiles. When faced with aluminum profiles with complex cross-sectional shapes and irregular shapes, it is difficult to effectively fix them due to the lack of an adjustable clamping structure. This limits the applicability of the clamps and cannot meet the processing needs of diverse aluminum profiles. Secondly, the existing fixtures lack auxiliary positioning structures. During the continuous processing of aluminum profiles, the cutting tools need to be repositioned and calibrated after each disassembly and replacement of the aluminum profile. This will affect the efficiency of aluminum profile processing and cannot meet the needs of high-efficiency production. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model relates to a fixture for aluminum profile processing. The fixture's clamping structure design is relatively simple, mostly suitable for fixing regular-shaped aluminum profiles. When dealing with irregularly shaped aluminum profiles with complex cross-sections, the lack of an adjustable clamping structure makes effective fixing difficult, limiting the fixture's applicability and failing to meet the diverse processing needs of aluminum profiles. Furthermore, existing fixtures lack auxiliary positioning structures. During continuous aluminum profile processing, the cutting tools need to be repositioned and calibrated after each disassembly and replacement of the aluminum profile, affecting processing efficiency and failing to meet the demands of high-efficiency production.

[0005] The first aspect of this utility model provides a fixture for processing aluminum profiles, achieved by the following specific technical means: A fixture for processing aluminum profiles, comprising: The base is rectangular in shape, with a double-ended lead screw rotatably mounted in the center. Adjustment grooves are provided on both sides of the base, extending through both sides. A movable frame is slidably mounted inside each adjustment groove, with both ends extending from the sides of the adjustment groove. Each movable frame is threadedly connected to the double-ended lead screw inside the base. A contact element is provided on the movable frame, consisting of two sets of rectangular plates hinged together. The two sets of rectangular plates are respectively engaged with the mounting grooves on the sides of the movable frame. The mating groove at the outer end of the contact element is engaged with the insert block in the mounting groove, and the fixing hole inside the contact element is engaged with the movable block inside the side of the movable frame.

[0006] Furthermore, a side groove is provided at the middle position on both sides of the base, and positioning grooves are provided at equal intervals at both ends of the side groove.

[0007] Furthermore, an ear plate is fixedly installed on the outside of the base, and a limiting block is provided in the side groove at the rear of the base. The upper end of the limiting block extends out from the side groove, and both ends of the limiting block are inserted into the positioning groove in the side groove.

[0008] Furthermore, the movable frame has a U-shaped structure, and mounting slots are provided on both outer ends of the movable frame, with insert blocks provided on the upper and lower sides of each set of mounting slots.

[0009] Furthermore, movable slots are provided on the inner ends of both sides of the movable frame. Movable blocks are slidably installed in the movable slots through springs, and both ends of the movable slots penetrate the movable frame. The ends of the movable blocks can extend into the mounting slots.

[0010] Furthermore, the contact element can be bent up to 90° along the hinge point of the two sets of rectangular plates, and the two ends of the contact element are hinged with auxiliary plates.

[0011] Furthermore, fixing holes are provided on both sides of the contact and inside the sub-plate, and mating grooves are provided at the upper and lower ends of the contact and the sub-plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this device, a bendable contact element is set on the movable frame, and hinged sub-plates are set at both ends of the contact element. When it is necessary to clamp irregular aluminum profiles, the contact element can be bent to 90° and the sub-plates are inserted into the mounting groove and engaged with the movable block, so that the contact element is fixed in a bent shape. This can effectively increase the contact area with irregular aluminum profiles, better adapt to aluminum profiles with complex cross-sectional shapes and irregular shapes, effectively improve the versatility of the fixture, and meet the diverse processing needs of aluminum profiles.

[0013] 2. In this device, side slots with positioning grooves are set at both ends of the base. Before processing, the limiting block is inserted into the corresponding position of the side slot through the positioning groove. During the continuous processing of aluminum profiles, when placing the aluminum profile, its rear end is pressed against the limiting block. With the help of two sets of moving frames to clamp the aluminum profile in the center, the aluminum profile is positioned and fixed. When processing the same type of aluminum profile in the future, it is only necessary to press the aluminum profile against the limiting block when clamping it. In this way, there is no need to recalibrate the tool positioning. The same processing procedure can be used to complete the processing, which reduces the processing preparation time and improves the processing efficiency of aluminum profiles.
