Technical Field
The invention relates to the field of numerical control blade machining, in particular to a numerical control blade blank and a method for quickly finding an inscribed circle of the numerical control blade blank.
Background
As shown in fig. 3 of the drawings, a front view of a numerically controlled blade is shown with its edge being a convex edge curve. The three groups of edge curves are in a central symmetry structure around the symmetry center.
In the production process of the numerical control blade shown in fig. 3, firstly, a blank of the blade is manufactured by a powder metallurgy mode, and after the blank is machined, curved surfaces represented by three groups of edge curves are finished by a peripheral grinding mode. The periphery of the blank is uniformly provided with grinding allowance.
Because the blank can't find the inscribed circle of three group edge curves fast in the clamping process, lead to the processing man-hour overlength and the processing to reserve too big and the too high problem of rejection rate.
Disclosure of Invention
The invention aims to solve the problems of overlong processing time, overlarge processing allowance, high rejection rate and the like in the processing process of workpieces of the type. The novel numerical control blade blank and the method for quickly finding the inscribed circle of the novel numerical control blade blank can achieve the effect of quickly processing and forming the blank.
In order to achieve the effect, the invention discloses a numerical control blade blank which comprises three groups of edge curved surfaces, wherein each group of edge curved surfaces is provided with a positioning plane, the positioning planes are in a centrosymmetric structure around the symmetric center of a blade blank workpiece, and the symmetric center is the center of an inscribed circle of the workpiece.
Further, the included angle between any two adjacent positioning planes is an acute angle.
The invention relates to a method for quickly finding an inscribed circle of a numerical control blade blank, which realizes the positioning of the blade blank through a fixed tool.
Further, the fixing tool comprises a tool A and a tool B, a tool positioning surface A is arranged on the tool A, and a tool positioning surface B is arranged on the tool B; the tool positioning surface A coincides with at least two positioning planes.
Further, the tool A is fixed, and the tool B moves towards the tool A to enable at least one group of positioning planes B to coincide with the positioning planes, so that the positioning of the workpiece is realized.
Further, the tool A is not fixed, and the tool A and the tool B move relative to each other to realize the positioning of the workpiece.
The invention has the beneficial effects that:
the positioning plane which is in a central symmetry structure around the symmetry center of the blade blank workpiece is arranged on the edge curved surface of the blade blank, and the effect of quickly positioning the inscribed circle of the blade blank is realized through the fixing tool with a special structure. The problems that the processing time is too long, the processing allowance is too large, the rejection rate is high and the like in the traditional technical mode are solved.
