The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
The embodiment discloses an axial calibration tool for grinding a crankshaft, which is used for realizing the calibration of the axial relative positions of a grinding wheel and an Nth main journal of the crankshaft; in the specific grinding, the axial direction of the grinding wheel (i.e. the thickness direction of the grinding wheel) is parallel to the axial direction of the crankshaft, so in this embodiment, after the axial calibration is completed, the center of the axial thickness of the grinding wheel and the center of the axial length of the nth main journal of the crankshaft are located in the same plane perpendicular to the axial direction, i.e. the grinding wheel and the nth main journal of the crankshaft are both located at the same axial position; thus, even if the grinding wheel is replaced, the axial relative position of the grinding wheel and the crankshaft is determined through axial alignment. The crankshaft generally has a plurality of main journals, and connecting journals are disposed between adjacent two of the main journals, where the nth main journal is one of the main journals.
Referring to fig. 1 to 3, the axial alignment fixture 100 includes an alignment reference member having an L-shaped structure, the alignment reference member including a first alignment base 11 and a second alignment base 12, the first alignment base 11 having a first end and a second end along an axial direction (i.e., an X direction in the drawings), the first end being for contact with an end face of the grinding wheel 200; the second calibration matrix 12 is vertically connected to the second end; the second calibration base 12 has a first positioning surface 121 and a second positioning surface 122 that are perpendicular to each other, and the first positioning surface 121 abuts on the outer circumferential surface of the M-th main journal 302 of the crankshaft 300. The nth main journal 301 and the mth main journal 302 are different main journals, and in this embodiment, the axial alignment of the grinding wheel 200 and the nth main journal 301 is performed by using the alignment reference material based on the mth main journal 302. The M-th main journal 302 is provided with a first shoulder 303 and a second shoulder 304 on both sides in the axial direction, respectively, the second shoulder 304 being further away from the N-th main journal 301 than the first shoulder 303; in particular, the second positioning surface 122 of the second calibration matrix 12 is flush with the second end of the first calibration matrix 11 and abuts the second shoulder 304. Here, let the axial length of the first calibration matrix 11 (i.e., the axial distance from the first end to the second end) be a, the axial distance from the center of the axial length of the nth main journal 301 to the second shoulder 304 be B, and the axial thickness of the grinding wheel 200 be D, a=b-0.5D.
In particular, since the axial length of the first calibration base 11 is set to be a fixed value, and the assembly position relationship of the first calibration base 11 on the crankshaft 300 is also determined, when the grinding wheel 200 moves to the position where the end face of the grinding wheel 200 contacts the first end of the first calibration base 11, the axial relative position calibration of the grinding wheel 200 and the crankshaft 300 is completed according to a=b-0.5D, when the center of the axial thickness of the grinding wheel 200 is located at the same position in the axial direction as the center of the axial length of the nth main journal 301; in summary, the calibration tool of the embodiment is simple and convenient to operate when performing calibration work, is helpful to shorten the calibration time, and the accuracy of calibration can be ensured.
Of course, in practical implementation, in order to avoid that the first calibration matrix 11 will be worn when the grinding wheel 200 contacts with the first end of the first calibration matrix 11, the axial length of the whole first calibration matrix 11 is shortened after multiple calibrations, which affects the accuracy of subsequent calibrations, and the grinding wheel 200 may be calibrated in place without contacting with the first end of the first calibration matrix 11, but with a fixed gap value, so that the axial calibration may be completed and the abrasion of the first calibration matrix 11 may not be caused. Thus, in some other embodiments, after the grinding wheel 200 is aligned in place, a gap of L is maintained with the first end of the first alignment substrate 11, at which point the axial length a of the first alignment substrate 11 = B-0.5D-L; thus, every time the grinding wheel 200 is moved to a position spaced apart from the first end of the first calibration base 11, the grinding wheel 200 is still located at the same position in the axial direction as the nth main journal 301 of the crankshaft 300, and the calibration work is normally performed. Alternatively, L may be 0.1mm.
Further, the axial calibration fixture 100 further includes a clamping member, where the clamping member includes a first connecting rod 13, a second connecting rod 14, and a tightening member 15; the first connecting rod 13 and the second calibration matrix 12 are axially arranged at intervals; the first link 13 is further away from the nth main journal 301 relative to the second calibration matrix 12; the second connecting rod 14 extends along the axial direction and connects the second calibration matrix 12 and the first connecting rod 13; the jack 15 is provided on the first link 13 and is movable in the axial direction with respect to the first link 13 until it abuts against the crankshaft 300. The above arrangement of the clamping member can fix the whole calibration reference member on the crankshaft 300, ensure the stable placement of the calibration reference member, realize the stable placement of the calibration reference, and ensure the corresponding calibration operation; meanwhile, the worker does not need to hold the axial calibration tool 100 to keep the axial calibration tool motionless, and can also free hands to feed the grinding wheel 200, so that the calibration work can be completed by one person, and the labor is saved.
In one embodiment, the puller 15 abuts the connecting rod neck 306 that is connected to the second shoulder 304. In particular, the second shoulder 304 connects the mth main journal 302 and the connecting journal 306 that is further from the nth main journal 301 relative to the mth main journal 302; further, the connecting rod neck 306 is provided with a third shoulder 307 on the side not connected to the mth main journal 302, and the jack 15 abuts against the third shoulder 307. In another embodiment, according to the different lengths of the second connecting rod 14, the propping member 15 may not only be abutted against the connecting rod neck 306, but also be abutted against other main journals or connecting rod necks 306, and specifically abutted against corresponding shoulder structures, so long as the relative fixing of the whole axial alignment tool 100 and the crankshaft 300 can be achieved.
Specifically, the tightening member 15 includes a screw 151 and a rotary handle 152, the screw 151 is disposed on the first connecting rod 13 through a threaded structure, the screw 151 has a third end and a fourth end along an axial direction, and the third end is used for abutting against the crankshaft 300; the rotation handle 152 is provided at the fourth end of the screw 151. Specifically, the rotary handle 152 is disposed perpendicular to the screw 151, similar to a rotary lever, so that a person can conveniently rotate the entire screw 151, and the rotary motion is converted into linear motion of the screw 151 along the axial direction through the threaded engagement between the screw 151 and the first link 13, so as to finally realize the offset with the crankshaft 300. Specifically, an external thread is disposed on the outer peripheral surface of the screw 151, a through hole is formed on the first connecting rod 13, an internal thread is disposed on the wall of the through hole, and the internal thread is in threaded fit with the external thread, so as to realize the assembly of the screw 151 and the first connecting rod 13. Further, the third end of the screw 151 is provided with a buffer 153 to avoid crushing the workpiece while abutting against the crankshaft 300. Optionally, the cushioning member is a rubber member.
Illustratively, the first positioning surface 121 is provided with a V-shaped groove 1211, and the V-shaped groove 1211 has a first inclined surface and a second inclined surface that are disposed at an included angle, and the first inclined surface and the second inclined surface are both abutted against the outer circumferential surface of the mth main journal 302. Because the outer circumferential surface of the M-th main journal 302 is in a cylindrical structure, if the first positioning surface 121 is a plane, the placement stability of the second calibration matrix 12 is poor and the assembly is not good, so that the placement stability of the second calibration matrix 12 can be improved by forming the V-shaped groove 1211 on the first positioning surface 121; obviously, the included angle of the V-shaped groove is an obtuse angle, and the two inclined surfaces of the V-shaped groove are tangential to the outer circumferential surface of the mth main journal 302.
Further, a first rounded corner 123 is disposed at the connection between the first positioning surface 121 and the second positioning surface 122, a second rounded corner 305 is disposed at the connection between the mth main journal 302 and the second shoulder 304, and the radius of the first rounded corner 123 is larger than that of the second rounded corner 305. Generally, in order to avoid stress concentration at the joint of the main journal and the shoulder, a round angle is arranged between the main journal and the shoulder; therefore, the first fillet 123 needs to be disposed between the first positioning surface 121 and the second positioning surface 122, and the radius of the first fillet 123 is larger than that of the second fillet 305, so that the two positioning surfaces can be smoothly contacted with the mth main journal 302 and the second shoulder 304, respectively. Optionally, the radius of the first rounded corner 123 is 0.5mm greater than the radius of the second rounded corner 305.
Illustratively, the first end of the first calibration matrix 11 is stepped to form a plurality of reference surfaces 111 at the first end that are perpendicular to the axial direction and are axially spaced apart; the reference surface 111 is for contact with the end surface of the grinding wheel 200. For a certain type of crankshaft 300, a corresponding reference surface 111 can be selected, and during the calibration operation, the end surface of the grinding wheel 200 is contacted with the selected reference surface 111, so that the calibration of the type of crankshaft 300 can be completed. Therefore, the arrangement of the multiple datum planes can improve the applicability of the whole calibration tool, so that the tool can be suitable for the crankshafts 300 of different types to implement calibration and positioning; at this point, the axial length a of the first calibration matrix 11 should be understood as the axial distance of the selected one of the reference surfaces 111 to the second end. In this embodiment, referring to fig. 1, two reference surfaces 111 are formed at a first end of a first calibration matrix 11.
Further, the first calibration matrix 11 is detachably connected to the second calibration matrix 12. In specific implementation, the axial length of the first calibration matrix 11 can be changed by changing the first calibration matrix 11, so as to provide more choices and be suitable for calibrating more types of crankshafts 300; of course, the removable manner also facilitates timely replacement when the first calibration matrix 11 wears out. Optionally, the first calibration matrix 11 and the second calibration matrix 12 are detachably connected by a screw structure.
In a specific embodiment, the nth main journal 301 is a seventh main journal, and referring to fig. 2 and 3, the crankshaft 300 is assembled to the grinding machine by a dedicated jig 400, and since the jig 400 covers the seventh main journal, the sixth main journal may be used as the mth main journal 302 for calibrating the axial relative positions of the grinding wheel 200 and the seventh main journal. Specifically, when the axial calibration operation is performed, the first positioning surface 121 of the second calibration substrate 12 is abutted against the outer circumferential surface of the sixth main journal, the second positioning surface 122 is abutted against the shoulder between the fifth connecting rod journal and the sixth main journal, and the tightening member 15 is abutted against the shoulder between the fifth connecting rod journal and the fifth main journal, so that the assembly of the axial calibration fixture 100 is completed.
Note that the above is only a preferred embodiment of the present invention and the technical principle applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
