[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0032] like Figures 3 to 8 The sheath assembly fixture shown includes a frame 1, a first clamping mechanism 2 and a second clamping mechanism 3, as shown in FIG. Figure 3 As shown in the figure, the frame 1 mainly plays a supporting role. The frame 1 can be formed by splicing profiles, or it can be welded and fixed with steel plates;
[0033] The first clamping mechanism 2 is fixed on the frame 1. The first clamping mechanism 2 has a first clamping assembly 21. The first clamping assembly 21 is used to clamp the wire harness. The wire harness here refers to the wire harness that has been crimped with the center pin 01. The first clamping assembly 21 has a variety of structural forms. For example, a clamping claw cylinder can be used to clamp the cable.
[0034] The second clamping mechanism 3 is arranged toward the first clamping mechanism 2, and has a sliding seat 31, a linear driving member 32 driving the sliding seat 31 to move toward or away from the first clamping mechanism 2, and a second clamping assembly 33 for clamping the sheath 02; the linear driving member 32 here can be a motor screw structure, and those skilled in the art can certainly select a specific driving form according to needs;
[0035] Please continue to refer to Figure 3 In an embodiment of the utility model, the second clamping assembly 33 is pivotally connected to the sliding seat 31, and the second clamping mechanism 3 also has an angle adjustment member 34, one end of the angle adjustment member 34 is rotatably connected to the sliding seat 31, and the other end is connected to the second clamping assembly 33. The angle adjustment member 34 is configured to press the second clamping mechanism 3 down to a set angle and then restore it when moving toward the first clamping mechanism 2, so as to avoid interference between the sheath 02 and the wiring harness during the plug-in process.
[0036] Specifically, when assembling the sheath 02, Figure 4 As shown in the figure, first, the first clamping component 21 for clamping the cable and the second clamping component 33 for clamping the sheath 02 are aligned, and the sheath 02 is moved toward the direction of the center needle 01. Before the center needle 01 enters into the sheath 02 and the front end of the sheath 02 has not yet reached the interference position with the cable, the angle of the sheath 02 is rotated downward by a certain angle so that the front end of the sheath 02 avoids the interference with the cable, and the sheath 02 is continued to be inserted until the front end of the sheath 02 exceeds the interference position with the cable, and then the sheath 02 is adjusted to the original angle. Through this arrangement, damage to the cable or the sheath 02 and interference between the sheath 02 and the cable are avoided, thereby improving the reliability of the assembly of the sheath 02.
[0037] In the above embodiment, the second clamping assembly 33 for clamping the sheath 02 is rotatably connected, and the angle of the second clamping assembly 33 is adjusted by the angle adjusting member 34, so that during the process of inserting the center needle 01 on the cable into the sheath 02, the center needle 01 is inserted into the sheath 02 for a certain distance and then presses down the sheath 02, and then the angle of the sheath 02 is restored after it is further inserted into place. Compared with the prior art, the change of angle during the plugging process avoids interference between the sheath 02 and the cable, and there is no need to damage the cable, thereby improving the reliability of the plugging.
[0038] Based on the above examples, please refer to Figure 6 and Figure 7 The second clamping assembly 33 is a clamping cylinder, which has two first clamping jaws 33a, and the surfaces of the two first clamping jaws 33a facing each other have clamping grooves 33b adapted to the sheath 02. Figure 7 As shown in , by means of the clamping grooves 33b provided on the two first clamping jaws 33a, the clamping accuracy of the sheath 02 can be improved, ensuring the reliability of the center needle 01 entering the sheath 02 each time when plugging.
[0039] The specific structure of the angle adjustment of the second clamping assembly 33 is as follows: Figure 6 As shown in the figure, the sliding seat 31 also has a pivot seat 35, which includes a bottom plate 35a connected to the sliding seat 31, a retaining wall 35b fixed on the bottom plate 35a, and a shaft chamber 35c connected to the retaining wall 35b; and also includes a connecting shaft 36 rotatably connected to the shaft chamber 35c, and a connecting plate 36a is connected to the radial direction of the connecting shaft 36, and the connecting plate 36a is connected to the second clamping assembly 33. It should be pointed out here that in some embodiments of the utility model, the connecting shaft 36 can be connected to the shaft chamber 35c by means of a bearing to improve the smoothness of rotation.
[0040] In addition, in some embodiments of the present invention, the connection height of the shaft chamber 35c on the retaining wall 35b can be adjusted. The height adjustment here can be adopted as follows Figure 6 This is achieved by the vertical straight hole structure set at the connection between the shaft chamber 35c and the retaining wall 35b shown in the figure. Through this structural setting, the height of the second clamping assembly 33 can be adjusted to adapt to the assembly of sheaths 02 of different specifications.
[0041] Please continue to refer to Figure 6 In the embodiment of the present invention, the upper part of the rotating shaft chamber 35c is provided with an opening, the connecting plate 36a is provided protruding from the upper part of the rotating shaft chamber 35c, and the rotating shaft chamber 35c also has limit plates 37 on both sides of the connecting shaft 36 in the swinging direction, and the limit plates 37 are used to limit the rotation angle of the second clamping assembly 33. That is, the limit plates 37 are provided at the front and rear ends of the rotating shaft chamber 35c, and through this arrangement, it is possible to prevent the sheath 02 from rotating too much and causing damage to the center needle 01. Of course, it should be pointed out here that in some embodiments of the present invention, the angle adjustment member 34 has a variety of structural forms, for example, the angle adjustment member 34 can be a cylinder or a hydraulic cylinder.
[0042] In the embodiment of the utility model, in order to further improve, the first clamping mechanism 2 also has an auxiliary clamp for centering the wire harness. Figure 8 As shown in , the auxiliary clamp includes a lifting mechanism 22 arranged below the front end of the first clamping assembly 21, and the lifting mechanism 22 includes a lifting cylinder 22a and a top plate 22b connected to the lifting cylinder 22a, and the highest point of the stroke of the top plate 22b is aligned with the lowest point when the wiring harness is plugged in. In the embodiment of the utility model, the bending of the center needle 01 can be avoided by setting the top plate 22b; further, the auxiliary clamp also includes a centering jaw 23, and the two jaws of the centering jaw 23 are arranged at the positions on both sides of the highest point of the top plate 22b, and the clamping center corresponds to the center of the cable. By setting the centering jaw 23, the center needle 01 can be avoided from being offset in the left and right directions; in addition, in the embodiment of the utility model, the auxiliary clamp also includes a pressing plate mechanism 24, and the pressing plate on the pressing plate mechanism 24 moves in the vertical direction, and the lowest point formed is set at the highest point when the cable is plugged in. In this way, by restricting in the four directions of up, down, left, and right, the center needle 01 is directly opposite to the hole position of the sheath 02, thereby further improving the reliability of the assembly of the sheath 02.
