Laser leveling device without physical adjustment, comprising a movement arrangement (10) and a cover arrangement (20) which are rigidly connected to each other, wherein the motion arrangement (10) comprises a motion holder (11) to which at least three connecting screw bolts (12) are attached, wherein an X-axis
spirit level (13), a Y-axis
spirit level (14) and a Z-axis
spirit level (15) are arranged on the motion holder (11), and wherein the cover arrangement (20) comprises a cover body (21) in which rigid spacer bolts (22) are attached to the cover body (21) by means of a sealing
adhesive, wherein the number of rigid spacer bolts (22) corresponds to the number of connecting screw bolts (12), the rigid spacer bolts (22) protrude from the cover body (21) and the rigid spacer bolts (22) and the connecting screw bolts (12) are connected to each other by screws; and wherein a mounting seat (30) for a lighting mechanism (40) is further attached to the motion holder (11), wherein the lighting mechanism (40) is attached to the mounting seat (30) for the lighting mechanism (40) by screws, and wherein at least three mounting projections (31) are arranged on the mounting seat (30) for the lighting mechanism (40), wherein a first screw hole (311) extends through an associated mounting projection (31) and the motion holder (11), and wherein the lighting mechanism (40) comprises a
light source support shell (41) in which a
light source (42) is mounted, and wherein an annular projecting mounting section (44) is attached to a side of the mounting plate (43) facing away from the
light emission of the
light source (42), wherein a gap is provided between the inner ring of the annular projecting mounting section (44) and the light source support shell (41),and wherein a number of second screw holes (441) corresponding to the number of mounting projections (31) are provided in the annular projecting mounting section (44), the second screw holes (441) extending through the mounting plate (43) and the positions of the second screw holes (441) being aligned with the positions of the first screw holes (311); , and wherein a
ball bearing mounting seat (211) is arranged on the lid body (21) in which a
ball bearing (212) is attached, wherein a rotary mechanism is arranged in the
ball bearing (212), and wherein a breaking mechanism (60) is attached at an output end at the upper end of the rotary mechanism; and wherein the end faces of the connecting screw bolts (12), the end faces of the rigid spacer bolts (22), the end face of the mounting projection (31) and the end face of the annular protruding mounting section (44) are each aligned parallel to an XY plane, and wherein the
optical axis of the light source (42) and the center of rotation of the rotary mechanism are each aligned parallel to a Z axis, while the
optical axis of the light source (42) and the center of rotation of the rotary mechanism are coaxial to each other.
