The invention provides a positioning mechanism for milling of filleted-corner parts and a machining technique for hook-head pressing plates of the positioning mechanism. The positioning mechanism comprises a base, a workpiece fixing movable block slidably connected with the base, and a power movable block in linkage with the workpiece fixing movable block, wherein a transmission shaft is arranged between the workpiece fixing movable block and the power movable block in a penetrating mode, and a thread pair is arranged on the transmission shaft; the hook-head pressing plates which penetrate through the workpiece fixing movable block and the power movable block are symmetrically machined on the two sides of the transmission shaft, and the two ends of each hook-head pressing plate extend out of the workpiece fixing movable block and the power movable block; and the transmission shaft rotates forwards / reversely to drive the workpiece fixing movable block and the power movable block to move close to / away from each other under the action of the thread pair, so that a workpiece is pressed / released. The positioning mechanism for milling of the filleted-corner parts and the machining technique for the hook-head pressing plates of the positioning mechanism are higher in precision, more accurate and capable of providing the industrial standard when used for machining the filleted-corner parts. The part machining precision is high, the product quality is stable, and the machining efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a milling positioning mechanism for rounded corner parts and a processing technology for hooking and pressing plates of the mechanism. Background technique [0002] In the field of mechanical manufacturing, there are a large number of irregular rounded parts. Such parts are complex in shape, cannot be processed by lathes, and need to be milled. Because such parts are rounded parts, the clamping on the milling machine is not firm, the datum alignment is difficult and there are accumulated errors, which makes the processing efficiency of the parts low and the accuracy difficult to meet the assembly requirements. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a milling positioning mechanism for rounded corner parts, which solves the existing technical problems of rounded corner parts...
