Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aluminum parts processing equipment, and in particular to a clamping device for aluminum parts processing. Background Technology
[0002] Aluminum alloy parts are widely used in aerospace, automotive electronics, mold making, and general equipment. They are characterized by low density, high thermal conductivity, and good machinability. However, their low elastic modulus, low surface hardness, and high coefficient of thermal expansion make them highly sensitive to clamping methods during CNC milling, drilling, tapping, and five-axis machining. Current production methods commonly use general-purpose machine vises with soft jaws, T-slot clamping plates, vacuum adsorption tables, expansion mandrels or expansion sleeves, adhesive wax for holding, and special rollers for extruded profiles for clamping to achieve positioning and clamping.
[0003] The existing technical solutions have the following drawbacks: Existing clamping technologies require multi-face machining when dealing with complex cavities or irregularly shaped parts. General-purpose fixtures have difficulty taking into account the correlation accuracy of hole positions, shapes and surface shapes when converting references. The consistency of repeated clamping and positioning is poor. At the same time, they cannot achieve quick changeover and adapt to multiple types of aluminum parts. Utility Model Content
[0004] The purpose of this invention is to provide a clamping device for aluminum parts processing, so as to solve the problems existing in the prior art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A clamping device for processing aluminum parts includes a base. A first circular hole is provided at the right end of the top of the base, with its axis vertically aligned. A first mounting groove is provided at the left end of the top of the base, communicating with the first circular hole. A second circular hole is provided at the left end of the top of the first mounting groove, with its axis vertically aligned. An integrally formed cylindrical protrusion is provided at the top of the second circular hole, with its axis collinear with the axis of the second circular hole. A third circular hole is provided at the left end of the bottom of the base, with its axis collinear with the axis of the cylindrical protrusion. A second mounting groove is provided at the right end of the bottom of the base. Integrally formed first rectangular protrusions are provided on both the left and right sides of the front end of the base.
[0007] By adopting the above technical solution, the combined design of the first circular hole, the first mounting groove, the second circular hole, and the cylindrical protrusion on the top of the base can achieve precise positioning of aluminum parts in multiple directions and with multiple references. This avoids the offset and shaking of aluminum parts during processing caused by the single positioning point or mismatched positioning structure of traditional clamping devices. This solves the problem of difficulty in ensuring the positional accuracy of aluminum parts after clamping, ensuring that the processing dimensions meet the design requirements. Stable clamping reduces downtime for adjustment during processing and shortens the preparation time when changing workpieces, thereby improving the overall processing efficiency.
[0008] In a further embodiment, a first rectangular groove is provided at the top right end of the second mounting groove, a second rectangular groove is provided at the front end of the first rectangular groove, the rear end face of the second rectangular groove is completely open and communicates with the first rectangular groove, a third rectangular groove is provided at the rear end of the first rectangular groove, the front end face of the third rectangular groove is completely open and communicates with the first rectangular groove, and a first through hole is provided in both the second rectangular groove and the third rectangular groove, with the axis of the first through hole being vertically set.
[0009] By adopting the above technical solutions, the utilization rate of installation space is optimized, the overall structural stability and processing convenience are improved, thereby ensuring the reliability of equipment operation and reducing subsequent maintenance costs.
[0010] In a further embodiment, the rectangular protrusion is provided with a second through hole that extends from front to back, and the axis of the second through hole is positioned front to back.
[0011] By adopting the above technical solution, the problem of connecting, positioning or penetrating components in the front-back direction during assembly or use is solved. The through holes with front-back penetration and the front-back axis provide operators with an intuitive and smooth operating path, which facilitates the quick and accurate completion of related operations and effectively improves the work efficiency of assembly or maintenance. In terms of structural stability, the stress dispersion problem of rectangular protrusions when subjected to front-back forces is solved.
[0012] In a further embodiment, the top of the first circular hole is provided with a plurality of upwardly integrally formed arcuate protrusions evenly distributed axially.
[0013] By adopting the above technical solution, the design of the arc protrusion can distribute stress to multiple protrusions and surrounding areas by changing the local structural shape, effectively reducing the stress value at a single point, improving the load-bearing capacity and service life of the overall structure, and the one-piece molding design of the arc protrusion does not require additional connecting parts, simplifying the processing technology. At the same time, the material continuity between the protrusion and the main body of the circular hole ensures the structural strength, thereby improving the operational stability and safety of the entire equipment.
[0014] In a further embodiment, the top of the first circular hole is provided with two integrally formed second rectangular protrusions.
[0015] By adopting the above technical solution, the problem of difficult positioning during use was solved, the stability of the structural connection was improved, and it played a guiding role in the work process, thereby improving production efficiency.
[0016] In a further embodiment, the horizontal axis of the second rectangular protrusion is positioned to the left and right, and the second rectangular protrusion is symmetrical about the horizontal axis of the first circular hole.
[0017] By adopting the above technical solutions, the stress of the surrounding structure can be evenly distributed, effectively avoiding local stress concentration, thereby enhancing the load-bearing capacity and fatigue resistance of the entire structure, extending its service life, and enabling rapid positioning and calibration during operation, reducing errors caused by positioning deviations and improving production efficiency.
[0018] In summary, this utility model has the following beneficial effects:
[0019] 1. The second mounting groove at the right end of the base bottom and the third round hole at the left end of the base bottom enable quick positioning and installation with the machine tool base;
[0020] 2. The first round hole and the first mounting groove on the top of the base enable the simultaneous processing of aluminum parts of various specifications;
[0021] 3. The second through hole on the first rectangular block enables quick positioning and installation. Attached Figure Description
