Embodiment 1

[0020] Such as Figure 1~2 As shown, a rectangular hole part includes a part main body 1, a rectangular square hole 2 and a grinding wheel overtravel groove 3. The rectangular square hole 2 is located on the part main body 1, and the four corners of the rectangular square hole 2 are grinding wheel overtravel grooves 3 .

[0021] A method of processing a rectangular hole part by using a curve grinder, comprising:

[0022] 1) Continuously send coolant at a flow rate of 5-10L / min to the surface of the part;

[0023] 2) Align the runout of the outer circle of the part to less than 0.01mm, and press the part tightly;

[0024] 3) Move the grinding wheel to the maximum or minimum radius of the part to be ground until sparks appear;

[0025] 4) Each cutting depth is 0.02mm;

[0026] 5) The cutting distance of the grinding wheel along the X axis is 0.888mm / table rotation once, until the rectangular square hole 2 is ground.

Abstract

The invention relates to a rectangular hole part and a method for processing the rectangular hole part by using a curve grinder. The rectangular square hole (2) is located on the part main body (1), and the four corners of the rectangular square hole (2) are grinding wheel overtravel grooves (3). The variation of the X-axis movement of the curve grinder and the variation of the C-axis rotation angle are combined, and the grinding of the rectangular square hole (2) is completed through the rotation of the worktable. The present invention can use universal equipment to complete the purpose of grinding rectangular holes without using special equipment.

Description

technical field [0001] The invention belongs to the technical field of numerical control processing, in particular to a rectangular hole part and a method for processing the rectangular hole part by using a curve grinder. Background technique [0002] The rectangular hole of a key part requires relatively high dimensional accuracy, positional accuracy and surface quality (see attached picture). Previously, the rectangular hole was milled by milling on a vertical machining center, but due to low machining accuracy, there was no Can meet the drawing requirements. [0003] In order to meet the requirements of the drawings, new technological solutions must be found. When looking for a new process plan, is it possible to use a curved grinder to grind a rectangular hole? Curve grinder can grind various curved surfaces, and plane is a special form of curved surface. [0004] The main function of the curve grinder is to grind the inner and outer curves of the straight generatrix ...
