Problems solved by technology

In the regrinding process, the existing knife grinder uses a single grinding wheel for grinding, such as figure 1 As shown, the inventors found that, for integral metal cutting slender end mills, such as gun drills, impeller mills, and deep hole drills, etc., due to their slenderness and poor rigidity, they are subjected to unilateral axial The effect of force is very prone to bending deformation, which affects the accuracy after regrinding and reduces the machining accuracy of the milling cutter; in addition, a single grinding wheel can only complete the regrinding and repairing of one blade in one stroke. When regrinding milling cutters with the number of blades, the single wheel grinder has the problem of low regrinding efficiency

Embodiment 2

[0053] This embodiment discloses a method for grinding an even-numbered milling cutter using the milling cutter grinding device described in Embodiment 1, such as Figure 7-8 shown, including the following steps:

[0054] Step 1: Fixedly connect the milling cutter with the tool movement assembly.

[0055] Step 2: Along the circumferential direction of the milling cutter circle, define multiple cutting edges as No. 1, No. 2...N 1 No. blade, where N 1 is an even number.

[0056] Step 3: The first grinding piece is in contact with the end of the blade k, and the second grinding piece is in contact with No. blade end contact, complete k blade and For the tool setting of the No. 1 blade, the first grinding part and the second grinding part work, the tool movement assembly drives the milling cutter to rotate, and at the same time, the second driving mechanism drives the tool to make a feed movement, the first grinding part and the second grinding part Parts along the directio...

Embodiment 3

[0066] This embodiment discloses a method for grinding a milling cutter with an odd number of blades using the milling cutter grinding device described in Embodiment 1, such as Figure 9-12 shown, including the following steps:

[0067] Step A: Fixedly connect the milling cutter with the tool movement assembly.

[0068] Step B: along the circumferential direction of the milling cutter circle, define multiple cutting edges as No. 1, No. 2...N 2 No. blade, where N 2 is an odd number.

[0069] Step C: First grinding piece with k 1 The end of the No. blade is in contact with the second grinding element with the No. cutting edge contact, where the second grinding part is in contact with the No. blade contact position distance The distance from the end of the number blade is L 1 , the first grinding part and the second grinding part are working, the cutter movement assembly drives the milling cutter to rotate, and at the same time, the second driving mechanism drives the c...

Abstract

The invention relates to a milling cutter grinding apparatus and a using method. The milling cutter grinding apparatus comprises a first grinding assembly and a second grinding assembly which are connected with a first drive mechanism and can move in the direction getting close to or away from each other in the first direction, a cutter motion assembly is arranged between the first grinding assembly and the second grinding assembly, the cutter motion assembly is connected to a second drive mechanism and can move in the second direction perpendicular to the first direction, the first grinding assembly includes a first bracket connected to the first drive mechanism, the first bracket is connected with a first grinding member, the second grinding assembly comprises a second bracket connectedto the first drive mechanism, the second bracket is provided with a third drive mechanism, the third drive mechanism is connected with a second grinding member and is capable of driving the second grinding member to move in the second direction, the axes of the first grinding member and the second grinding member are the same as the axis of the cutter motion assembly in height, and the first grinding member and the second grinding member are symmetrically distributed with respect to the axis of the cutter motion assembly. The grinding apparatus is high in working efficiency and avoids deformation of a milling cutter.

Description

technical field [0001] The invention relates to the technical field of milling cutter repair equipment, in particular to a milling cutter grinding device and a method of use. Background technique [0002] When the milling cutter is used under long-term working conditions, it is prone to wear and damage, which makes it unable to use normally. At present, the milling cutter that wears and damages takes place is usually regrinded and repaired by a knife grinder, and the knife grinder completes the grinding of the milling cutter blade through a grinding wheel. In the regrinding process, the existing knife grinder uses a single grinding wheel for grinding, such as figure 1 As shown, the inventors found that, for integral metal cutting slender end mills, such as gun drills, impeller mills, and deep hole drills, etc., due to their slenderness and poor rigidity, they are subjected to unilateral axial The effect of force is very prone to bending deformation, which affects the accur...
