As shown in fig. 3, the large arc section 9.1 is arc-shaped under the constraint of the conical surface 10 of the conical wheel 11, and the circle center of the arc-shaped large arc section 9.1 is on the axis of the conical wheel 11; the inner contour of the large arc section 9.1 is matched with the tangent plane contour 33 of the conical wheel 11 at the position of the large arc section 9.1, as shown in figures 4 and 5; the connection parts of the two ends of the large arc section 9.1 respectively form a first partial bending part 6.1 and a second partial bending part 6.2; the actual bending direction of the first partial bending part 6.1 and the second partial bending part 6.2 is opposite to the natural bending direction of the first partial bending part 6.1 and the second partial bending part 6.2, so as to achieve the effect of forced correction.
The angles of the first local bending part 6.1 and the second local bending part 6.2 are a, and the larger the angle a is, the smaller the bending strength of the first local bending part 6.1 and the second local bending part 6.2 is, and the smaller the angle a is, the larger the bending strength of the first local bending part 6.1 and the second local bending part 6.2 is.
As shown in fig. 2, 5 and 6, a balancing weight 15 is arranged between a front wire harness restraining roller 31 and a rear wire harness restraining roller 16, a pair of guide rods 17 extending vertically are fixed on the upper side of the balancing weight 15, the device further comprises a cantilever beam 18 fixed on a device bracket, a guide hole 19 for the guide rods 17 to vertically slide through is arranged on the cantilever beam 18, and the balancing weight 15 slides up and down under the restraint of the guide rods 17 and the guide holes 19; the two sides of the balancing weight 15 are respectively and fixedly provided with a first auxiliary shaft 24 and a second auxiliary shaft 25 which are parallel, the axes of the first auxiliary shaft 24 and the second auxiliary shaft 25 are vertically intersected with the conical surface 10 of the conical wheel 11, and the tail ends of the first auxiliary shaft 24 and the second auxiliary shaft 25 are respectively and rotatably provided with a first universal ball 22 and a second universal ball 23; the first universal ball 22 and the second universal ball 23 are always in rolling fit with the conical surface 10 of the cone pulley 11 under the gravity action of the balancing weight 15 no matter the cone pulley 11 rotates or displaces along the axis direction; the outer walls of the lower ends of the first auxiliary shaft 24 and the second auxiliary shaft 25 are respectively rotatably provided with a first auxiliary constraint roller 20 and a second auxiliary constraint roller 14 through bearings, and the large arc section 9.1 is clamped between the first auxiliary constraint roller 20 and the second auxiliary constraint roller 14 in a rolling way; under the mutual constraint of the first auxiliary constraint roller 20 and the second auxiliary constraint roller 14, the large arc section 9.1 does not deviate along the axis direction along with the cone pulley 11, and the large arc section 9.1 is always in a fully constrained state.
As shown in fig. 4, the axle center of the cone pulley 11 is rotatably mounted on the telescopic shaft 12 through a bearing 13, and the fixedly mounted linear telescopic device 30 drives the telescopic shaft 12 to stretch and retract along the axial direction, so as to drive the cone pulley 11 to displace along the axial direction.
In the process of gradually retracting the telescopic shaft 12, the diameter of the profile 33 of the tangent plane of the conical wheel 11 at the position of the large arc section 9.1 is gradually reduced, so that the diameter of the large arc section 9.1 is gradually reduced under the condition that the circle center is unchanged, the angles a formed at the first local bending part 6.1 and the second local bending part 6.2 are gradually increased, and the bending strength at the first local bending part 6.1 and the second local bending part 6.2 is reduced as the angle a is increased;
as shown in fig. 3, in the process of gradually extending the telescopic shaft 12, the diameter of the profile 33 of the tangent plane of the conical wheel 11 at the position of the large arc section 9.1 is gradually increased, so that the diameter of the large arc section 9.1 is gradually increased under the condition that the circle center is unchanged, the angles a formed at the first local bending part 6.1 and the second local bending part 6.2 are gradually reduced, and the bending strength at the first local bending part 6.1 and the second local bending part 6.2 is increased as the angle a is smaller.
The working method and principle of the advanced correction unit 1:
In the process of gradually leading out the wire harness 9 by the wire harness wire storage reel 5, the wire harness 9 is gradually led out by the wire harness wire storage reel 5 from the outermost wire harness 5.2 of the wire harness wire storage reel 5 as an initial leading-out point until the innermost wire harness 5.1 is finally led out; since the bending curvature of the "natural bending" of the wire harness 9 gradually increases from the outermost wire harness 5.2 to the innermost wire harness 5.1 on the wire harness cord reel 5, the bending curvature of the "natural bending" of the wire harness 9 gradually led out by the wire harness cord reel 5 gradually increases with the lapse of time in the process of gradually leading out the wire harness 9 by the wire harness cord reel 5, and thus the correction strength of the preceding correction unit 1 needs to be gradually increased in the process of continuously correcting the wire harness 9 gradually led out by the wire harness cord reel 5; the specific method comprises the following steps:
when the wire harness 9 is just started to be led out of the wire harness storage reel 5, the diameter of the section profile 33 of the conical wheel 11 at the position where the large arc section 9.1 is positioned is in a smaller state, the angles a at the first local bending part 6.1 and the second local bending part 6.2 are in a larger state, so that the bending strength at the first local bending part 6.1 and the second local bending part 6.2 is smaller, the first correcting unit 1 is in a low-strength correcting strength state, and the low-strength correcting unit is adapted to a state that the bending curvature of the natural bending of the wire harness 9 just started to be led out is smaller, so that the problem of excessive straightening is avoided;
in the process of continuously leading out the wire harness 9 from the wire harness storage coil 5 along with the time, the bending curvature of the natural bending of the led wire harness 9 gradually increases along with the time, meanwhile, the linear expansion device 30 gradually stretches out along with the time, the diameter of the section profile 33 of the conical wheel 11 at the position of the large arc section 9.1 gradually increases along with the gradual stretching out of the telescopic shaft 12, the diameter of the large arc section 9.1 gradually increases under the condition of unchanged circle center, the angle a formed by the first local bending part 6.1 and the second local bending part 6.2 gradually decreases, and the bending strength at the first local bending part 6.1 and the second local bending part 6.2 gradually increases along with the gradual shrinking of the angle a, so that the correction strength of the wire harness storage coil 5 continuously led out of the wire harness storage coil 5 by the preceding correction unit 1 gradually increases along with the gradual increasing trend of the bending curvature of the natural bending of the led wire harness 9, and the problem that right a wrong is insufficient while the excessive right a wrong is avoided.
As shown in fig. 7, the correction repair unit 2 includes a plurality of first repair wheels 7 arrayed equidistantly along the extending direction of the wire harness 9 and a plurality of second repair wheels 8 arrayed equidistantly along the extending direction of the wire harness 9, the wire harness 9 drawn from the preceding correction unit 1 being fitted between the plurality of first repair wheels 7 and the plurality of second repair wheels 8 in a rolling manner in a straight line direction; the correction and repair unit 2 is used for repairing the situation that the wire harness 9 led out by the preceding correction unit 1 is slightly overused or under-corrected, so that the corrected wire harness 9 is smoother.
The foregoing is only a preferred embodiment of the invention, it being noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the invention.
