Description
METHOD FOR GRINDING CRANKSHAFT JOURNAL 7502682
SYMMETRICALLY
The present disclosure belongs to the grinding technical field of a crankshaft journal, in particular to a method for grinding a crankshaft journal symmetrically.
Information disclosed in the background is merely intended to deep the understanding of the overall background of the present disclosure, rather than being regarded to acknowledge or imply, in any form, that the information has become the prior art known by those skilled in the art.
A crankshaft is one of core components of an internal combustion engine, the requirement on its processing precision is very high, so the finish machining of a journal and a round corner must be finished by the grinding of a grinding wheel. Referring to FIG. 1 and FIG. 2, as shown in the figure, in order to ensure the universality of the grinding wheel and save the processing cost, the size of the grinding wheel 1 along the axial direction of the journal 2 is usually less than the axial size of the journal 2, and the grinding wheel 1 is usually provided with a cylinder grinding portion 11 for grinding the cylinder outer side of the journal, a round corner grinding portion A12 for grinding one round corner of the journal and a round corner grinding portion
B13 for grinding another round corner of the journal. The existing Junker grinding machine mainly adopts a grinding machine process of “twice cutting method”: the first grinding can finish the grinding of the left side, the round corner and most journal (FIG. 1), namely, the round corner grinding portion A12 of the grinding wheel 1 grinds a first round corner of the journal, the cylinder grinding portion 11 grinds most cylinder outer side of the journal, and the outer side of the round corner grinding portion B13 is a non-grinding section 21 of the journal; and the second grinding can finish the grinding of the right side, the round corner and partial journal (FIG. 2), namely, the round corner grinding portion A13 of the grinding wheel 1 grinds a second round corner of the journal, the cylinder grinding portion 11 grinds the remaining cylinder outer side of the journal, and the outer side of the round corner grinding portion A12 is a grinding section 22 of the journal. It has found, through analysis, that the two sides of the grinding wheel 1, closing to the round corner grinding portion A12 and the round corner grinding portion B13, have different use and wearing states: the side, closing to the round corner grinding portion A12, of the grinding wheel 1 is ground once, namely, the round corner grinding portion A12 of the grinding wheel 1 will contact with the non-grinding portion of the journal 2 during the first grinding, and the round corner grinding portion A12 will not contact with the non-grinding portion of the journal 2 during the second grinding; and the side, closing to the round corner grinding portion B13, of the grinding wheel 1 is ground twice, namely, the round corner grinding portion B13 of the grinding wheel 1 will contact with the non-grinding portion of the journal 2 during the first grinding, and the round corner grinding portion B13 of the grinding wheel 1 will also contact with the non-grinding portion of the journal 2 during the second grinding. Since each journal 2 adopts the same grinding cutting method, namely, the first round corner is ground through the round corner grinding portion A12, then the second round corner is ground through the round corner grinding portion B13, resulting in seriously wearing the side, closing to the round corner grinding portion B13, of the grinding wheel 1. In order to ensure the processing precision, the grinding wheel 1 is trimmed frequently, thereby causing the cost and efficiency waste.

Namely, when the grinding wheel 3 grinds the journal in the even section for the first time, the round corner grinding portion A32 of the grinding wheel 3 grinds the first round corner of the journal 4, and the cylinder grinding portion 31 of the grinding wheel 3 grinds most cylinder outer side of the journal 4; when the grinding wheel 3 grinds the journal in the even section for the second time, the round corner grinding portion B33 of the grinding wheel 3 grinds the second round corner of the journal 4, and the cylinder grinding portion 31 of the grinding wheel 3 grinds the remaining cylinder outer side of the journal 4; when the grinding wheel 3 grinds the journal in the odd section for the first time, the round corner grinding portion B33 of the grinding wheel 3 grinds the first round corner of the journal 4, and the cylinder grinding portion 31 of the grinding wheel 3 grinds most cylinder outer side of the journal 4; and when the grinding wheel 3 grinds the journal in the odd section for the second time, the round corner grinding portion A32 of the grinding wheel 3 grinds the second round corner of the journal 4, and the cylinder grinding portion 31 of the grinding wheel 3 grinds the remaining cylinder outer side of the journal 4. LU502682
Specifically, when the grinding wheel 3 grinds the even section of journal, such as a second section, a fourth section and a sixth section, firstly, the round corner grinding portion
A32 of the grinding wheel 3 is roughly aligned with an axial end of the journal 4, the grinding wheel 3 performs grinding along a radial direction of the journal 4 and closing to the journal 4, and after grinding, the outer side of the round corner grinding portion B33 of the grinding wheel 3 is a non-grinding section 41 of the journal 4; and then the grinding wheel 3 is away from the journal 4 along the radial direction of the journal 4; then the grinding wheel 3 translates along the axial direction of the journal 4, afterwards the ground round corner grinding portion B33 of the grinding wheel 3 is roughly aligned with another axial end of the journal 4, the grinding wheel 3 performs grinding along the radial direction of the journal 4 and closing to the journal 4, and before grinding, the outer side of the ground round corner grinding portion A32 of the grinding wheel 3 is a grinding section of the journal 4; when the grinding wheel 3 grinds the odd section of journal, such as a first section, a third section and a fifth section, firstly, the round corner grinding portion B33 of the grinding wheel 3 is roughly aligned with an axial end of the journal 4, the grinding wheel 3 performs grinding along a radial direction of the journal 4 and closing to the journal 4, and after grinding, the outer side of the round corner grinding portion A32 of the grinding wheel 3 is a non-grinding section 41 of the journal 4; and then the grinding wheel 3 is away from the journal 4 along the radial direction of the journal 4; then the grinding wheel 3 translates along the axial direction of the journal 4, afterwards the ground round corner grinding portion A32 of the grinding wheel 3 is roughly aligned with another axial end of the journal 4, the grinding wheel 3 performs grinding along the radial direction of the journal 4 and closing to the journal 4, and before grinding, the outer side of the ground round corner grinding portion B33 of the grinding wheel 3 is a grinding section of the journal 4.

In a preferred implementation mode of the embodiment, the grinding wheel 3 has different poses when grinding different journals, and the grinding wheel 3 has the opposite moving direction. Namely, the grinding wheel 3 only moves along the radial direction and the axial direction of the journal without adjusting the pose; and by changing the axial moving direction of the grinding wheel, the grinding wheel can be regulated to alternately cut into the journal with the round corner grinding portion A and the round corner grinding portion B. For example, when the grinding wheel grinds the even sections, such as the second section, the fourth section and the sixth section, firstly, the grinding wheel cuts into the journal from a leftmost end of the journal, and then the grinding wheel cuts into the journal from a rightmost end of the journal; and when the grinding wheel grinds the odd sections, such as the first section, the third section and the fifth section, firstly, the grinding wheel cuts into the journal from a rightmost end of the journal, and then the grinding wheel cuts into the journal from a leftmost end of the journal.
