DETAILED DESCRIPTION

[0020] The following is a further description of the specific embodiments of the present invention in conjunction with the accompanying drawings, which do not limit the present invention. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0021] A feeding and pulling device for facilitating automobile wiring harness processing, such as Figure 1 As shown, it includes a traction frame 1 and several traction wheel groups 2. The traction frame 1 includes a horizontal frame top plate 11, a horizontal frame bottom plate 12 and several vertical columns connected therebetween. A traction motor 31 is fixed on the frame bottom plate 12. The output end of the traction motor 31 is connected to the traction main shaft 3. The traction motor 31 drives the traction main shaft 3 to rotate, thereby driving each traction wheel group 2 to rotate for traction.

[0022] like Figure 1 As shown, the traction wheel assembly 2 includes two upper and lower traction wheel units 21, with a gap provided between the two traction wheel units 21 for the wire harness to pass through. The traction wheel assembly 2 is slidably connected to the traction main shaft 3, and one of the traction wheel units 21 (the lower one) is driven to rotate by the traction main shaft 3. The two traction wheel units 21 can be non-contacting, and the friction of the wire harness can drive the other traction wheel unit 21 to rotate. Alternatively, the two traction wheel units 21 can be meshed with each other through gears or directly in frictional contact with each other to improve the traction effect on the wire harness.

[0023] In this embodiment, linear slide rails are connected to the frame top plate 11 and the frame bottom plate 12, and corresponding slide grooves are opened on the upper and lower sides of the traction wheel group 2 to guide the traction wheel group 2 to slide along the traction main shaft 3 in the traction frame 1 for installation.

[0024] like Figure 1 and Figure 2 As shown, the traction frame 1 is further provided with a plurality of limit blocks 4 distributed along the length direction of the traction main shaft 3. The limit blocks 4 are rotatably connected to the traction frame 1, and their rotational positions block or leave the moving path of the traction wheel group 2. Specifically, one end of the limit block 4 is hinged, and the other end can be moved up and down. When it is lifted upward to a horizontal position, it leaves the moving path of the traction wheel group 2, and when it is rotated downward from the horizontal direction, it blocks the moving path of the traction wheel group 2.

[0025] In this embodiment, the limiting block 4 is rotationally connected below the rack top plate 11, and the free end thereof can be rotated downward from the horizontal direction by an acute angle, and the end of the hinged end is rotated upward to abut against the lower side of the rack top plate 11, thereby limiting the rotation angle range; in some embodiments, the limiting block 4 is manually pushed upward to facilitate the installation of the traction wheel set 2, and then the limiting block 4 falls down under the action of gravity and abuts against the side of the traction wheel set 2 (or part of it also abuts against the upper end of the traction wheel set 2, without falling down); the limiting block 4 can also be adsorbed below the rack top plate 11 by magnetic attraction, which facilitates the installation of the traction wheel set 2, and then the free end thereof is manually pushed downward to make it lose the magnetic attraction effect.

[0026] As shown in Figure 1 , in some embodiments, the limiting block 4 is arranged between adjacent traction wheel sets 2, that is, the spacing between the limiting blocks 4 is adapted to the width of the traction wheel set 2, and this kind of way can only limit the traction wheel set 2 in several fixed positions, and the number of limiting blocks 4 used is less, but the flexibility is lower;

[0027] In some other embodiments, the limiting blocks 4 are arranged under the rack top plate 11, part of which is located between adjacent traction wheel sets 2, and part of which is located above the traction wheel set 2, so that the spacing between the traction wheel sets 2 can be set as any multiple of the width of the limiting block 4, so that the installation position of the traction wheel set 2 is more, and the more the number of limiting blocks 4 used, the higher the flexibility of the installation position.

[0028] As shown in Figure 1 and Figure 2 , in some embodiments, the traction wheel set 2 further comprises a positioning plate 5, the inner side of the positioning plate 5 is connected with a positioning block 51, and a corresponding positioning groove is formed in the traction wheel body 21 connected with the traction main shaft 3 (the positioning groove can be formed in the middle of the linear groove of the traction wheel body 21, or can be formed on the outer periphery of the two side plates), and the positioning block 51 positions the traction wheel body 21 at a set angle for connection with the traction main shaft 3.

[0029] Specifically, the traction main shaft 3 in this embodiment is a spline (it can also be connected with the traction wheel body 21 by means of a flat key), and when it is installed, the corresponding traction wheel body 21 needs to be rotated to a specific angle to be installed on the traction main shaft 3, but the installation position is not convenient to observe, so the positioning block 51 and the positioning groove are arranged to temporarily fix the angle of the traction wheel body 21, the positioning groove is provided with one or more, corresponding to the angle of the inner peripheral spline groove of the traction wheel body 21 and the traction main shaft 3, and after being temporarily fixed by the positioning block 51, the traction wheel body 21 can be directly slid into the traction rack 1 and connected with the traction main shaft 3, without the need to repeatedly adjust the angle of the traction wheel body 21.

[0030] As shown in Figure 2As shown, in the embodiment, the positioning plate 5 is connected with the integral side connecting plate 52 on both sides, the linear slot 53 is formed on the side connecting plate 52, the side plate rotating shaft 22 is fixedly connected with the traction wheel set 2 on both sides, the side plate rotating shaft 22 is located in the linear slot 53, before installation, the positioning plate 5 is pulled inwards along the linear slot 53 until the side plate rotating shaft 22 abuts against the outer end of the linear slot 53, the positioning block 51 is inserted into the corresponding traction wheel unit 21, and the angle of the traction wheel unit 21 is temporarily fixed so as to be connected with the traction main shaft 3, after installation, the positioning plate 5 is pulled outwards and is placed down under the action of the weight (the side plate rotating shaft 22 finally abuts against the inner end of the linear slot 53), the positioning plate 5 finally abuts against the outer side of the traction wheel set 2, and the traction wheel unit 21 is loosened to rotate freely.

[0031] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and the modification or equivalent replacement should also be regarded as falling within the protection scope of the technical scheme of the present application.
