DETAILED DESCRIPTION

[0031] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0032] like Figure 1 Shown: A winding tool, including a self-centering chuck 1, a chuck rotating base 2 and a rotating drive mechanism.

[0033] The n claws of the self-centering chuck 1 include two wire harness end clamping claws and n-2 coil supporting claws 1.3, n is an integer greater than or equal to 3, and in this embodiment, n is equal to 4; the self-centering chuck 1 is controlled by an external adjustment mechanism to move the n claws equidistantly relative to the chuck center to complete the support and release of the coil, that is, the external adjustment mechanism is connected to the square holes on the self-centering chuck 1, and then drives the claw driving mechanism of the self-centering chuck 1, and the claw driving mechanism drives the four claws to approach or withdraw from the chuck center.

[0034] The rotary drive mechanism is used to drive the chuck rotary base 2 to rotate.

[0035] The chuck rotating base 2 includes a fixed part and a rotating part. The fixed part is fixed to a supporting structure. The supporting structure can be a machine table, a bracket, etc. for installing a winding tool. The rotating part rotates in the fixed part. The self-centering chuck 1 is connected to the rotating part and rotates coaxially with the rotating part. When the self-centering chuck 1 rotates, the wire harness is wound around the four claws.

[0036] like Figure 5As shown: the two wire harness end clamping claws of the self-centering chuck are the junction box clamping claw 1.1 and the wire harness tail clamping claw 1.2; the junction box clamping claw 1.1 is used to clamp one end of the wire harness at the beginning of winding, and the wire harness tail clamping claw 1.2 is used to clamp the other end of the wire harness at the end of winding.

[0037] The junction box clamping claw 1.1 includes a first winding rod 1.1.1, a first slider 1.1.2 and a junction box holder 1.1.3, and the first winding rod 1.1.1 and the junction box holder 1.1.3 are installed on the first slider 1.1.2; the junction box holder 1.1.3 can limit the movement of the junction box of the wiring harness in the up and down directions, the left and right directions and the backward directions, the plugging and unplugging direction of the junction box holder 1.1.3 is inclined downward, and the plugging and unplugging direction is the forward direction. The junction box holder 1.1.3 has a notch that allows the wiring harness to move in and out up and down; the junction box of the wiring harness is clamped on the junction box holder 1.1.3 by an external manipulator, and the junction box holder 1.1.3 falls off the junction box when the junction box clamping claw 1.1 moves toward the center of the chuck.

[0038] The wire harness tail clamping claw 1.2 includes a second winding rod 1.2.1, a second slider 1.2.2 and a pressure rod 1.2.3. The second winding rod 1.2.1 is installed on the second slider 1.2.2. The pressure rod 1.2.3 is hinged to the second slider 1.2.2, and a spring is connected between the pressure rod 1.2.3 and the second slider 1.2.2. Before the dead point position, the spring pulls the pressure rod 1.2.3 close to the second winding rod 1.2.1 to clamp the wire harness. After the dead point position, the spring pulls the pressure rod 1.2.3 close to the second slider 1.2.2 to release the restraint on the wire harness.

[0039] The coil supporting claw 1.3 comprises a third winding rod 1.3.1 and a third slider 1.3.2, and the third winding rod 1.3.1 is mounted on the third slider 1.3.2.

[0040] The junction box of the wire harness from the previous process is first clamped onto the junction box holder 1.1.3. At this time, the previous process has not completely released the wire harness. The junction box clamping claw 1.1 drags the wire harness, and the self-centering chuck 1 rotates. While rotating, the previous process releases the wire harness until the tail of the wire harness passes through the wire harness tail clamping claw 1.2, and then the external equipment pushes the pressure rod 1.2.3 to rotate past the dead point position. The pressure rod 1.2.3 clamps the tail of the wire harness, and the wire harness winding is completed. Then it is tied by equipment from other processes or manually.

[0041] When the bound wire harness is removed from the self-centering chuck, the external device pushes the pressure rod 1.2.3 to rotate past the dead point position, the pressure rod 1.2.3 moves away from the second winding rod 1.2.1, loses the clamping effect on the wire harness, the four claws approach the center of the chuck, releases the support for the coil, and when the junction box clamping claw 1.1 moves toward the center of the chuck, the junction box falls off the junction box holder 1.1.3.

[0042] The first winding rod 1.1.1, the second winding rod 1.2.1 and the third winding rod 1.3.1 are all provided with indentations that match the wire harness and are used to position the coil.

A spring is connected between the limit rod 17 and the rotating part.

[0045] In the first state, the rotation drive mechanism is disconnected from the rotating part, and the spring applies force to the limit rod 17 so that the limit rod 17 maintains a posture with one end embedded in the bayonet 21 of the fixed part and the other end extending into the socket 18. The locking mechanism is locked and the rotating part of the chuck rotating base 2 cannot rotate.

[0046] In the second state, the rotary drive mechanism engages with the rotating part, and the rotary drive mechanism extends into the socket 18 to push one end of the limit rod 17 out of the socket 18. At the same time, the other end of the limit rod 17 also disengages from the bayonet 21, and the locking mechanism is unlocked.

The photoelectric sensor 15 feeds back the number of rotations of the male docking block 6 to monitor the number of windings of the wiring harness.

[0052] The photoelectric contact 14 is mounted on an adjustment plate 16 on the male docking block 6. The adjustment plate 16 is provided with an arc groove 16.1 centered on the rotation axis of the driving end of the rotating assembly 3.
