TECHNICAL FIELD
[0001] The utility model relates to aluminum alloy section bar processing technical field, concretely is a kind of special frock of milling of arc section thin-walled aluminum workpiece. BACKGROUND
[0002] The whole milling processing of thin-walled arc-shaped aluminum section bar workpiece is usually a difficult and time-consuming process, which is difficult in that: the arc section thin-walled aluminum workpiece requires high design of frock clamp, both to ensure that the workpiece can be clamped firmly and to prevent the workpiece from being deformed due to excessive clamping force; secondly, due to the large vibration of the thin-walled aluminum workpiece during milling, a good support must be formed around the processing part of the workpiece during milling to prevent the phenomenon of uneven milling position and excessive burrs due to excessive vibration. SUMMARY
[0003] The utility model aims to provide a kind of special frock of milling of arc section thin-walled aluminum workpiece, it is especially suitable for being installed on ordinary numerical control milling machine workbench, and the milling processing of thin-walled aluminum section bar workpiece edge;With clamping firm, thin-walled workpiece is not deformed, milling process vibration is small, and processing quality is good and so on.
[0004] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:
[0005] A kind of special frock of milling of arc section thin-walled aluminum workpiece, base is fixed on workbench, several arc surface fixed frock units are fixed on base, each arc surface fixed frock unit includes lower pressure cylinder on one side, the pressure head shape of lower pressure cylinder piston rod end part matches the shape of one side edge of aluminum workpiece;Arc surface fixed frock unit includes the other side edge top block, and the shape of edge top block matches the shape of the other side edge of aluminum workpiece.
[0006] Base is fixedly connected with the T-shaped groove of lower workbench by bolt, aluminum workpiece is obliquely placed on frock, and both ends are fixed by pressure head and edge top block, and the edge to be processed on the upper side is exposed and milled by processing tool;According to the length of workpiece, several frock units can be designed and installed on base, on the other hand, base is also divided into two parts, and the distance between the two half bases can also be adjusted to realize the use of frock units of various lengths.
[0007] End top plate is arranged on the side surface of the arc surface fixed frock unit at the last end. End top plate is used for positioning the end of workpiece, so that the workpiece is accurately placed on the frock for positioning processing.
[0008] The end top plate is hinged on the side surface of the arc surface fixed frock unit. End top plate can be manually lifted or lowered, and it is convenient to take and place workpiece when lifted.
[0009] The arc surface support is tightly attached to the arc surface of the aluminum workpiece, and not only plays a role of stably supporting the workpiece, but also can absorb most of the vibration during milling, preventing the machining quality of the thin-walled workpiece from being affected by the vibration.
[0010] The use method of the utility model is as follows:
[0011] (1) the end top plate is put down, the aluminum workpiece is put into the tool, and is embedded into the groove of the edge top block on one side, and the end of the workpiece is topped on the end top plate;
[0012] (2) the lower pressing cylinder is pressed down to tightly fix the workpiece;
[0013] (3) the milling operation is carried out;
[0014] (4) the lower pressing cylinder is lifted, the end top plate is manually lifted, and the workpiece is unloaded, that is, the milling operation of the workpiece is completed;
[0015] Advantages of the utility model
[0016] 1. The utility model is specially used for the milling positioning of the arc-shaped cross-section thin-walled aluminum workpiece, is suitable for being installed on the workbench of a general numerical control milling machine, has the advantages of stable clamping, no deformation of the thin-walled workpiece, small vibration in the milling process, good machining quality and the like.
[0017] 2. The utility model can be used for the milling machining of aluminum workpieces of various lengths, and has strong adaptability.
[0018] 3. The utility model is small in size and low in cost, and can maximize the efficient machining of the thin-walled arc surface aluminum workpiece under the premise of low cost. DRAWINGS
