Embodiment 1

[0030] Embodiment 1: as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 and Figure 8 Shown, a kind of flange top grinding method comprises the following steps;

[0031] Step 1, adding a first process screw hole 6 and a second process screw hole 7 on the tapered surface of the workpiece 9, and the first process hole 6 and the second process hole 7 are distributed symmetrically with the screw hole 8 in a triangle;

[0032] Step 2. Make fixture 1. Fixture 1 has an inner conical surface that matches the cone surface of workpiece 9. Fixture 1 also has holes that match the positions of first process hole 6, second process hole 7 and screw hole 8 of workpiece 9. screw hole;

[0033] Step 3. Grinding the end face, so that the workpiece 9 reaches the size required by the drawing, 20mm on the left, and ensure that the runout of the end face is within 0.003, leaving a margin of 0.1 to 0.15 on the right of 20mm;

[0034] Step 4. Connect the workpie...

Abstract

The invention relates to a flange centre grinding method, and belongs to the technical field of machining. A process screw hole is formed in one end of the centre face of a workpiece to be processed,a tool combined to a centre and matched with the centre in size is manufactured, the process screw hole and a screw hole in one end of the centre face are in triangular symmetric distribution, the triangular layout conforms to the requirement for the stability of a clamping surface, and the workpiece to be processed is clamped on the tool through the process screw hole for grinding. The flange centre grinding method has the advantages that processing of parts is completed, and various accuracy requirements of the parts are ensured. The tool is simple, practical and low in cost, the efficiencyis improved, the quality is ensured, and the actual problems at the production site are effectively solved.

Description

technical field [0001] The invention relates to a flange top grinding method, which belongs to the technical field of machining. Background technique [0002] A short tail taper shank 90°flange top, due to the limitation of conditions, if it is used in the common grinding method of 60° Morse taper shank, that is, the method of using the top and reverse top positioning grinding method has certain difficulties. [0003] The previous processing method is to use the method of top and anti-top positioning: [0004] Step 1. Make anti-top tooling; [0005] Step 2. Complete the machining of threaded holes for tooling before the fine grinding process; [0006] Step 3. Finely grind the 90° conical surface and the outer circle with the cylindrical grinder; [0007] Step 4, the center hole grinder grinds the center hole at the end of the tail handle; [0008] Step 5. Finely grind the 7°7′30" cone surface on the cylindrical grinder. [0009] According to this grinding method, due to...
