[0029] Moreover, although the present invention is described with reference to specific embodiments, it should be understood that these embodiments are merely examples of the principles and applications of the present invention. It should therefore be understood that many modifications may be made to the exemplary embodiments, and other arrangements may be designed without departing from the spirit and scope of the present invention as defined by the appended claims. It should be understood that the features described in the various dependent claims and herein may be combined in a manner not described in the original claims. It may also be understood that the features described in conjunction with the individual embodiments may be used in other described embodiments.

[0030] To solve the above problems, Figure 1As shown, the utility model provides a wire harness shaping tool, including a mold base 1, a fixed mold 2, a movable mold 3 and a driving mechanism 6, the fixed mold 2, the movable mold 3 and the driving mechanism 6 are respectively connected to the mold base 1, and a clamping cavity 8 for clamping a target part of a wire harness 7 is formed between the fixed mold 2 and the movable mold 3, and the driving mechanism 6 is used to drive the movable mold 3 to slide on the mold base 1 relative to the fixed mold 2 to adjust the clamping distance between the fixed mold 2 and the movable mold 3.

[0031] In this embodiment, by setting up the mold base 1, an installation position is provided for the fixed mold 2 and the movable mold 3. At the same time, by connecting the fixed mold 2 and the movable mold 3 to the mold base 1, and forming a clamping cavity 8 between the fixed mold 2 and the movable mold 3, it is convenient to place the part of the wire harness 7 that needs to be hardened, that is, the calibration part, in the clamping cavity 8, so that the fixed mold 2 and the movable mold 3 are used to clamp and fix the target part of the wire harness 7 according to the set direction. Moreover, by arranging a driving mechanism 6 on the mold base 1, and making the driving mechanism 6 drive the movable mold 3 to slide on the mold base 1 toward or away from the fixed mold 2, when it is necessary to shape the wire harness 7 with different outer diameters, the driving mechanism 6 can be used to drive the movable mold 3 to move to adjust the clamping distance between the movable mold 3 and the fixed mold 2, so that the target part of the wire harness 7 with different outer diameters can be placed in the clamping cavity 8 between the movable mold 3 and the fixed mold 2, and then the driving mechanism 6 drives the movable mold 3 to move toward the fixed mold 2 until the movable mold 3 and the fixed mold 2 are in contact with both sides of the wire harness 7 respectively, and continues to drive the movable mold 3 to move to squeeze the target part of the wire harness 7 until the shape of the target part of the wire harness 7 is the same as the shape of the clamping cavity 8. After the target part of the wire harness 7 is shaped, the driving mechanism 6 drives the movable mold 3 to slide in the direction away from the fixed mold 2, so as to take out the shaped wire harness 7. In this way, the wire harness shaping tool can be suitable for fixed shaping of wire harnesses 7 with different outer diameters. Compared with the prior art of using a single shaping tool to shape the wire harness 7, this can reduce the development cost of the wire harness shaping tool and ensure that the shapes of the wire harness 7 with different outer diameters after shaping are the same as the shape of the clamping cavity 8, that is, the shapes of the wire harnesses 7 with different outer diameters after shaping remain consistent.

[0032] Specifically, the shapes of the movable mold 3 and the fixed mold 2 located above the mold base 1 (i.e., the positive direction of the Z axis) are consistent, and can be a bent structure or an arc-shaped plate structure. The shapes of the fixed mold 2 and the movable mold 3 above the mold base 1 can be sufficient to enclose the clamping cavity 8, and are not specifically limited here. Among them, the fixed mold 2 and the movable mold 3 located above the mold base 1 serve as the two side walls of the clamping cavity 8, and the portion of the mold base 1 located in the space enclosed by the movable mold 3 and the fixed mold 2 can serve as the bottom wall of the clamping cavity 8. The shape of the clamping cavity 8 used by the movable mold 3 and the fixed mold 2 to clamp the wire harness 7 can be adaptively changed. For example, the clamping cavity 8 can be designed to be a straight line, a folded line, or an S shape, etc. The specific shape can be determined according to the installation environment of the wire harness 7. The shape of the wire harness 7 after shaping can be changed by changing the shape of the clamping cavity 8, so that the wire harness 7 can better adapt to its installation environment.

[0033] Alternatively, if Figure 3 As shown, the driving mechanism 6 includes a cam 61 and a driving member 62 . The cam 61 abuts against a side of the movable mold 3 away from the fixed mold 2 and is rotatably connected to the mold base 1 . The driving member 62 is used to drive the cam 61 to rotate.

[0034] In this embodiment, a cam 61 and a driving member 62 are provided, wherein the cam 61 is connected to the mold base 1 and can rotate relative to the mold base 1, the cam 61 abuts against the side of the movable mold 3 away from the fixed mold 2, and when the cam 61 rotates, the movable mold 3 can be pushed to slide on the mold base 1 relative to the fixed mold 2, and the driving member 62 can drive the cam 61 to rotate. For example, the driving member 62 can be a handle connected to the cam 61, and the handle can be manually rotated to rotate the cam 61; the driving member 62 can also be a motor, which drives the cam 61 to rotate.

[0035] Specifically, a through hole for the positioning column to pass through can be opened at the center of the cam 61. When the driving member 62 is a handle, the positioning column is inserted into the through hole and connected to the mold base 1. The cam 61 can rotate with the positioning column as the axis. When the driving member 62 is a motor, the motor shaft can be connected to the cam 61 through the through hole to drive the cam 61 to rotate. The type of the driving member 62 can be any type as long as it can drive the cam 61 to rotate, and no specific limitation is made here. On the mold base 1, a limit block can also be provided on the rotation path of the cam 61. The limit block can limit the rotation angle of the cam 61. When the movable mold 3 slides away from the fixed mold 2, the limit block can hinder the rotation of the cam 61 to prevent the movable mold 3 from moving too far, thereby preventing the movable mold 3 from detaching from the mold base 1.

[0036] Alternatively, if Figure 2 , Figure 3 and Figure 5As shown, the movable mold 3 includes a first clamping portion 31, and the first clamping portion 31 and the fixed mold 2 form the clamping cavity 8. The mold base 1 is provided with a first guide structure 11, and the first clamping portion 31 is provided with a second guide structure 32. The first guide structure 11 is slidably connected with the second guide structure 32.

[0037] In this embodiment, a first clamping portion 31 is provided, wherein the first clamping portion 31 is usually located on the upper surface of the mold base 1 (i.e., the surface of the mold base 1 located in the positive direction of the Z-axis), the first clamping portion 31 and the fixed mold 2 form a clamping cavity 8, a second guide structure 32 is provided on the first clamping portion 31, and a first guide structure 11 is provided on the mold base 1. For example, the second guide structure 32 is a pulley, and pulleys are provided at both ends of the movable mold 3 (i.e., the two ends of the movable mold 3 in the X-axis direction). Correspondingly, the first guide structure 11 can be a vertical plate, and vertical plates are respectively provided at positions where the two pulleys on the mold base 1 are opposite to each other. Slide rails are provided on the vertical plate in the direction of the pulleys, and the two slide rails are respectively slidably connected to the two pulleys to confine the pulleys and the movable mold 3 in the vertical plate, limit the sliding direction of the movable mold 3, and facilitate the movable mold 3 to slide on the mold base 1.

[0038] Alternatively, if Figure 3 and Figure 5 As shown, the first guide structure 11 and the second guide structure 32 are respectively one of the first guide block and the first guide groove, and the groove wall of the first guide groove is used to limit the first guide block from moving in a direction perpendicular to the plane where the mold base 1 is located.

[0039] In this embodiment, by setting the first guide structure 11 as one of the first guide block and the first guide groove, correspondingly, the second guide structure 32 is the other of the first guide block and the first guide groove, the first guide block can be embedded in the first guide groove and slidably connected with the first guide groove, for example, the first clamping portion 31 is provided with a first guide block at one end facing the mold base 1, and the mold base 1 is provided with a first guide groove, and the first guide block is embedded in the first guide groove to slidably connect the first clamping portion 31 with the movable mold 3, and the opening area of ​​the first guide groove on the upper surface of the mold base 1 (that is, the surface of the mold base 1 facing the positive direction of the Z axis) is at least smaller than the cross-sectional area of ​​the part of the first guide groove located in the mold base 1 along the XY plane, so that the groove wall of the first guide groove can limit the movement of the first guide block in a direction perpendicular to the plane where the mold base 1 is located, that is, limit the movement of the first guide block in the Z axis direction.

[0040] Specifically, the cross-section of the first guide groove and the first guide block in the XZ plane may be a trapezoid, the trapezoid comprising a long side, a short side and two waists, wherein the short side of the trapezoid is located on the upper surface of the mold base 1 (i.e., the surface of the mold base 1 facing the positive direction of the Z axis), and the long side of the trapezoid is located away from the interior of the mold base 1; the cross-section of the first guide groove and the first guide block in the XZ plane may also be a circle with an opening, wherein the length of the open end of the circle is less than the diameter of the circle, and the open end of the circle is located on the upper surface of the mold base 1 (i.e., the surface of the mold base 1 facing the positive direction of the Z axis). The shapes of the first guide groove and the first guide block only need to satisfy the requirement that the groove wall of the first guide groove can limit the movement of the first guide block in a direction perpendicular to the plane where the mold base 1 is located, and no specific limitation is made here.

[0041] Alternatively, if Figure 2 and 5 As shown, the movable mold 3 also includes a boss portion 33, the first guide structure 11 is arranged on the boss portion 33, and one side of the boss portion 33 is connected to the side of the first clamping portion 31 away from the fixed mold 2, and the other side of the boss portion 33 is used to abut against the cam 61.

[0042] In this embodiment, by setting a boss portion 33 on the side of the first clamping portion 31 away from the fixed mold 2, the first guide structure 11 can be opened on the boss portion 33, and the side of the boss portion 33 away from the first clamping portion 31 abuts against the cam 61. When the cam 61 rotates, it can push the boss portion 33 to make the movable mold 3 slide on the mold base 1. The setting of the boss portion 33 enhances the structural strength of the movable mold 3 and prevents the first clamping portion 31 from directly abutting against the cam 61, thereby preventing the first clamping portion 31 from deforming under the abutment pressure of the cam 61.

[0043] Specifically, the surface shape of the side where the boss portion 33 abuts against the cam 61 corresponds to the shape of the peripheral surface of the cam 61, which facilitates the cam 61 to roll on the surface of the boss portion 33 facing the cam 61, so that the boss portion 33 is subjected to more uniform force, thereby making the sliding of the first guide structure 11 and the second guide structure 32 smoother.

[0044] Alternatively, if Figure 1 As shown, the wire harness shaping tool also includes a first fixing seat 4 and / or a second fixing seat 5, the first fixing seat 4 is connected to the mold base 1, and is used to fix one end of the target part of the wire harness 7, and the second fixing seat 5 is connected to the mold base 1, and is used to fix the other end of the target part of the wire harness 7.

[0045] In this embodiment, a first fixing seat 4 and / or a second fixing seat 5 are provided on the mold base 1, and the first fixing seat 4 and the second fixing seat 5 are respectively located at two ends of the target portion of the wire harness 7, i.e., two ends of the clamping cavity 8, and the wire harness 7 is fixed on the mold base 1 to prevent the wire harness 7 from being offset during the shaping process.

[0046] Specifically, the first fixing seat 4 or the second fixing seat 5 can be set on the mold base 1 alone, or the first fixing seat 4 and the second fixing seat 5 can be set at the same time. When the first fixing seat 4 or the second fixing seat 5 is set alone, the fixing ability of the wire harness 7 is smaller than when the first fixing seat 4 and the second fixing seat 5 are set at the same time.

[0047] Alternatively, if Figure 3 and Figure 6 As shown, the first fixing seat 4 and / or the second fixing seat 5 is provided with a third guide structure 43 , the mold base 1 is provided with a fourth guide structure 12 , and the third guide structure 43 is slidably connected to the fourth guide structure 12 .

[0048] In this embodiment, a fourth guide structure 12 is provided on the mold base 1, and a third guide structure 43 is provided at one end of the first fixed seat 4 and / or the second fixed seat 5 facing the mold base 1. The third guide structure 43 is slidably connected to the fourth guide structure 12, so that the first fixed seat 4 and / or the second fixed seat 5 can slide on the mold base 1. When the wire harness 7 is shaped, the movable mold 3 and the fixed mold 2 are clamped on both sides of the wire harness 7 to shape the target part of the wire harness 7. At this time, the first fixed seat 4 and / or the second fixed seat 5 slide in a direction away from the clamping cavity 8, and the wire harness 7 is stretched away from both ends of the clamping cavity 8, so as to prevent overlapping wrinkles from occurring in the shaped part of the wire harness 7 and enhance the shaping effect.

[0049] Specifically, the third guide structure 43 can be a slider, and the fourth guide structure 12 can be a slide groove. The slider can be embedded in the slide groove and slidably connected with the slide groove. The side wall of the slide groove can limit the movement of the slider in the Z-axis direction. The structural relationship between the third guide structure 43 and the fourth guide structure 12 is the same as the structural relationship between the first guide structure 11 and the second guide structure 32, and no specific limitation is made here. The first fixed seat 4 and the second fixed seat 5 can be slidably connected to the mold base 1 separately, or can be slidably connected to the mold base 1 at the same time, wherein the effect of the first fixed seat 4 and the second fixed seat 5 simultaneously stretching the wire harness 7 is stronger than the effect of the first fixed seat 4 or the second fixed seat 5 stretching the wire harness 7 separately.

[0050] Alternatively, if Figure 3 and Figure 4 As shown, the fixed mold 2 includes a second clamping portion 21 and a fixing portion 22. A fixing groove 13 is provided on the mold base 1. The fixing portion 22 is used to be embedded in the fixing groove 13. The second clamping portion 21 is connected to the side of the fixing portion 22 away from the movable mold 3, and forms the clamping cavity 8 with the fixed mold 2.

[0051] In this embodiment, by providing a second clamping portion 21 and a fixing portion 22 that are connected to each other, the second clamping portion 21 is located on the side of the mold base 1 facing the positive direction of the Z axis, that is, above the mold base 1; the fixing portion 22 is embedded in the fixing groove 13 opened on the mold base 1 to fix the second clamping portion 21 on the mold base 1, and the second clamping portion 21 is located on the side of the fixing portion 22 away from the movable mold 3. The second clamping portion 21 and the first clamping portion 31 form a clamping cavity 8. The fixing portion 22 and the fixing groove 13 are provided to make the connection between the second clamping portion 21 and the mold base 1 more stable. In the process of squeezing the wire harness 7 between the second clamping portion 21 and the movable mold 3 to shape the wire harness 7, the fixing portion 22 provides support force for the second clamping portion 21 to prevent the second clamping portion 21 from falling off from the mold base 1 under the action of the wire harness 7.

[0052] Specifically, connection holes are provided on the fixing portion 22 at positions corresponding to the fixing slot 13, and bolts or pins can be passed through the connection holes to fix the fixing portion 22 in the fixing slot 13. The fourth guide structure 12 is located on the extension line of the fixing slot 13 toward one end of the fourth guide structure 12. In this embodiment, during the sliding process of the movable mold 3 toward the fixed mold 2, when the first clamping portion 31 and the second clamping portion 21 clamp the wire harness 7, the first fixed seat 4 and the second fixed seat 5 are respectively located at the left and right ends of the target part of the wire harness 7 (that is, the two ends of the target part of the wire harness 7 in the X-axis direction), and the fixed groove 13 is located between the first clamping portion 31 and the second clamping portion 21, and is connected to the second clamping portion 21, that is, the first fixed seat 4 and the second fixed seat 5 are respectively located at the left and right ends of the fixed groove 13 (that is, the two ends of the fixed groove 13 in the X-axis direction), and the fourth guide structure 12 is colinearly arranged with the extension line of the fixed groove 13 toward one end of the fourth guide structure 12, that is, the direction in which the first fixed seat 4 and / or the second fixed seat 5 pull the wire harness 7 to extend is the same as the direction in which the wire harness 7 exceeds the clamping cavity 8, which facilitates the first fixed seat 4 and / or the second fixed seat 5 to pull the wire harness 7 to move away from the clamping cavity 8.

[0053] Alternatively, if Figure 7 As shown, the clamping cavity 8 includes a first cavity 81, a second cavity 82 and a third cavity 83 which are connected in sequence, the first cavity 81 and the second cavity 82 are arranged at a right angle or an obtuse angle, the second cavity 82 and the third cavity 83 are arranged at a right angle or an obtuse angle, and the first cavity 81 and the third cavity 83 are respectively located on both sides of the second cavity 82.

[0054] In this embodiment, by setting a first cavity 81, a second cavity 82 and a third cavity 83 which are connected in sequence and are all straight, and the first cavity 81 is connected to one end of the second cavity 82 at a right angle or an obtuse angle, and the other end of the second cavity 82 is connected to the third cavity 83 at a right angle or an obtuse angle, the first cavity 81 and the third cavity 83 are respectively connected to both sides of the second cavity 82, so that the clamping cavity 8 is in a fold line shape as a whole, so that the clamping cavity 8 can shape the target part of the wiring harness 7 into a fold line shape, and the shaped wiring harness 7 is easy to adapt to its installation environment.

[0055] Alternatively, if Figure 3 and Figure 6 As shown, the first fixed seat 4 includes a first seat body, the first seat body includes a base 41 and a pressure plate 42, the third guide structure 43 is arranged on the base 41, one end of the pressure plate 42 is hinged to the base 41, and the other end is used for detachable connection with the base 41, and the base 41 is also provided with a first groove 411, and the pressure plate 42 is provided with a second groove 421, the first groove 411 and the second groove 421 are combined to form a through-hole structure, and the wiring harness 7 is used to pass through the through-hole structure.

[0056] In this embodiment, a first seat body is set, the first seat body includes a base 41 and a pressure plate 42, a third guide structure 43 is connected to the base 41, and the pressure plate 42 is connected to the side of the base 41 away from the mold base 1, wherein one end of the pressure plate 42 is hinged to one end of the base 41, and the other end of the pressure plate 42 is detachably connected to the other end of the base 41, and a first groove 411 is provided on the base 41 at one end facing the pressure plate 42, and a second groove 421 is provided on the pressure plate 42 at a position opposite to the first groove 411. When the pressure plate 42 is connected to the base 41, the first groove 411 and the second groove 421 are combined to form a through-hole structure for the wiring harness 7 to pass through, and the first seat body fixes the wiring harness 7 on the mold base 1 through the through-hole structure.

[0057] Specifically, a threaded hole is provided at one end of the pressing plate 42 and the base 41 that are detachably connected.
