Description

Technical Field

[0001] This utility model relates to the field of wire harness bending technology, and in particular to a wire harness bending fixture. Background Technology

[0002] Before use, wire harnesses on electrical components usually need to be bent according to the location of the connectors. For example, wire harnesses with both ends connected to the same circuit board need to be bent into an arc shape. In the existing technology, most of these bending operations are done manually, which increases the labor burden on users.

[0003] To address the aforementioned problems, those skilled in the art have made improvements to the existing technology. For example, Chinese Patent Publication No. CN216966117U discloses a wire harness bending fixture, which includes a first clamping arm and a second clamping arm hinged together. The clamping portions of the two clamping arms form a clamping space that matches the head of the wire harness and can be held in the clamping position. At least one hook component is also provided near the handle of the clamping arm for hooking the safety switch at the tail of the wire harness. This can assist the user in completing the wire harness bending operation. However, the above device achieves the positioning of the wire harness by clamping the wire harness connector, which makes the wire harness connector easily damaged, and the bending process is relatively cumbersome. When it is necessary to bend a large number of wire harnesses, it still cannot meet the needs of production efficiency.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this utility model is to provide a wire harness bending fixture that can automatically adjust the position of the auxiliary claw during the movement of the support seat to ensure a good wire harness bending effect, and can also automatically lift the wire harness after it has been bent into shape, making it easier for the user to pick up the wire and improving the efficiency of continuous operation.

[0006] To achieve the above objectives, this utility model provides a wire harness bending fixture, comprising: a base with a bending seat at one end, the bending seat having a bending groove; a movable seat slidably disposed on the top surface of the base, the movable seat having a plurality of connecting shafts, each connecting shaft having an end plate at its end, the end plate being elastically connected to a transmission plate slidably disposed on the connecting shaft; a bearing seat slidably disposed above the base, the bearing seat having a side plate located between the movable seat and the transmission plate, each side of the side plate having an extension plate, each extension plate having a guide shaft slidably inserted inside, each end of the guide shaft having a fixed seat connected to a fixed seat, each fixed seat having a fixed magnet on its side closest to each other, each extension plate having a movable magnet at its end; a limiting plate disposed at the end of the bearing seat near the bending seat, the limiting plate having two auxiliary claws symmetrically slidably disposed on the bearing seat on the side of the limiting plate away from the bending seat, the movable seat having a driven plate passing through the end plate and the transmission plate, and an adjusting connecting rod rotatably disposed between the driven plate and the auxiliary claws.

[0007] According to the wire harness bending fixture of this utility model, a support is fixedly provided on the bearing seat between the two auxiliary claws, and the driven plate passes through the support.

[0009] According to the wire harness bending fixture of this utility model, each telescopic shaft includes an inner rod and an outer rod. One end of the inner rod is slidably disposed inside the outer rod. A torsion spring is provided at the connection between the outer rod and the boss. A limiting spring that is always in a compressed state is provided between the inner rod and the outer rod.

[0010] According to the wire harness bending fixture of this utility model, the movable base and the side plate are provided with corresponding auxiliary magnets, and the two auxiliary magnets, the fixed magnet and the movable magnet attract each other.

[0011] According to the wire harness bending fixture of this utility model, a compression spring is provided between the end plate and the transmission plate. The force generated when the compression spring deforms is greater than the sum of the attraction between the auxiliary magnets and the attraction between the fixed magnet and the moving magnet.

[0012] The purpose of this utility model is to provide a wire harness bending fixture, which has the following beneficial effects:

[0013] 1. By setting a movable auxiliary claw, it can not only ensure a good wire harness bending effect, but also automatically retract the wire harness after bending and shaping, making it convenient for users to pick up the wire and improving work efficiency. In addition, the position of the auxiliary claw can be automatically adjusted during the movement of the carrier, without the need for additional drive components, thus reducing manufacturing and usage costs.

[0014] 2. By setting up structures such as lifting components, drive plates, and push shafts, the wire harness can be automatically lifted after it is bent and formed and the device is reset, which further reduces the difficulty of wire picking operations and ensures good continuous operation efficiency.

[0015] In summary, the beneficial effects of this utility model are: it can automatically adjust the position of the auxiliary claw during the movement of the support seat to ensure a good wire harness bending effect, and it can automatically lift the wire harness after it is bent into shape, making it easier for the user to pick up the wire and improving the efficiency of continuous operation.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0021] See Figures 1-3 This utility model provides a wire harness bending fixture, comprising:

[0022] The base 1 is located on the supporting plane. A bending seat 11 is fixedly connected to one end of the top surface of the base 1. A bending groove is opened on the surface of the bending seat 11. Two auxiliary seats 12 are fixedly connected to the side of the bending seat 11 near the center of the base 1. The two auxiliary seats 12 are respectively located on both sides of the bending groove. The distance between the two auxiliary seats 12 is greater than the width of the bending groove.

[0023] A movable seat 2 is located on the top surface of the end of the base 1 away from the bending seat 11. The movable seat 2 is slidably connected to the base 1. A telescopic member 21 is provided on the side of the movable seat 2 away from the bending seat 11. The telescopic member 21 is fixedly installed on the top surface of the base 1. The output shaft of the telescopic member 21 is connected to the movable seat 2. The telescopic member 21 can drive the movable seat 2 to reciprocate on the top surface of the base 1. Several connecting shafts 22 are fixedly connected to the side wall of the movable seat 2 away from the telescopic member 21. An end plate 23 is fixedly connected to the end of each connecting shaft 22 away from the movable seat 2. A transmission plate 25 is provided between the movable seat 2 and the end plates 23. The connecting shafts 22 all pass through the transmission plate 25. A compression spring 24 is provided between the end plate 23 and the transmission plate 25.

[0024] A support base 3 is located on the top surface of the base 1. An upward-facing side plate 31 is fixedly connected to the end of the support base 3 away from the bending seat 11. The side plate 31 is located between the movable seat 2 and the transmission plate 25. Connecting shafts 22 all pass through the side plate 31. Extension plates 32 are fixedly connected to the side walls at both ends of the side plate 31. Guide shafts 4 pass through the extension plates 32, and fixed seats 41 are fixedly connected to both ends of the guide shafts 4. Fixed seats 41 are fixedly connected to the top surface of the base 1. A movable magnet 33 is fixedly connected to the end of the extension plate 32 away from the side plate 31. Supports 13 are provided on the sides of the fixed seats 41 that are close to each other. Supports 13 are fixedly connected to the base 1, and fixed magnets 14 are fixedly connected to the supports 13. When the extension plate 32 abuts against the fixed seat 41, the fixed magnets 14 correspond to the movable magnets 33, and the fixed magnets 14 exert an attractive force on the movable magnets 33.

[0025] A limiting plate 34 is located at one end of the bearing seat 3 near the bending seat 11. The limiting plate 34 is fixedly connected to the top surface of the bearing seat 3. Two auxiliary claws 5 are symmetrically arranged on the side of the limiting plate 3 away from the bending seat 11. The auxiliary claws 5 are slidably connected to the bearing seat 3. The direction of movement of the auxiliary claws 5 relative to the bearing seat 3 is perpendicular to the direction of movement of the bearing seat 3 relative to the base 1. A driven plate 26 is fixedly connected to the side wall of the movable seat 2 near the bending seat 11. The driven plate 26 extends through the end plate 23 and the transmission plate 25 and extends between the two auxiliary claws 5. An adjusting rod 27 is rotatably connected between the driven plate 26 and the auxiliary claws 5. That is, one end of the adjusting rod 27 is rotatably connected to the driven plate 26, and the other end of the adjusting rod 27 is rotatably connected to the auxiliary claws 5. When there is relative movement between the driven plate 26 and the bearing seat 3, the two auxiliary claws 5 can be driven to move closer or further away from each other synchronously under the action of the adjusting rod 27. A support 6 is fixedly connected to the base 1 between the two auxiliary claws 5. The driven plate 26 passes through the support 6. The support 6 can provide auxiliary support for the driven plate 26 without hindering the relative movement between the driven plate 26 and the bearing seat 3.

[0026] The lifting component 7 is located on the side of the limiting plate 34 away from the bearing seat 3, and is situated between the two auxiliary claws 5. During operation, the lifting component 7 is positioned below the wiring harness. The end of the lifting component 7 away from the limiting plate 34 is fixedly connected to a vertical plate. Both sides of the support seat 6 are fixedly connected to protrusions 61. A telescopic shaft 62 is rotatably connected between the protrusions 61 and the vertical plate. One end of the telescopic shaft 62 is rotatably connected to the protrusion 61, and the other end is rotatably connected to the vertical plate. Each telescopic shaft 62 includes an outer rod and an inner rod. One end of the inner rod slides through the interior of the outer rod and is rotatably connected to the vertical plate. The outer rod is rotatably connected to the protrusion 61. A limiting spring is connected between the inner rod and the outer rod. The limiting spring is always in a compressed state. A torsion spring is provided at the connection between the outer rod and the protrusion 61. When the torsion spring is in its natural state, the bottom surface of the lifting component 7 abuts against the top surface of the bearing seat 3. A drive plate 8 is fixedly connected to each end plate 23. The end of each drive plate 8 away from the end plate 23 extends between the two auxiliary claws 5. A vertical bracket 81 is fixedly connected to the top surface of the end of each drive plate 8 away from the end plate 23. A push shaft 82 that can cooperate with the telescopic shaft 62 is fixedly connected to each vertical bracket 81. When the drive plate 8 moves away from the bending seat 11 relative to the bearing seat 3, the push shaft 82 abuts against and pushes the telescopic shaft 62 to rotate clockwise (to...). Figure 3 (For the view reference), during this process, the limit spring extends, thereby causing the lifting member 7 to lift the wire harness a certain distance.

[0027] See Figures 1-3 Preferably, the movable base 2 and the side plate 31 are both fixedly connected with corresponding auxiliary magnets 28, and the two auxiliary magnets 28 can attract each other.

[0028] See Figures 1-3 Preferably, the elastic coefficient of the compression spring 24 is set such that the force generated when it deforms is greater than the sum of the attraction between the fixed magnet 14 and the movable magnet 33 and the attraction between the two auxiliary magnets 28.

[0029] See Figures 1-3 Preferably, the telescopic component 21 is a telescopic electric cylinder, which can provide sufficient power.

[0030] See Figures 1-3 Preferably, the width of the limiting plate 34 is less than the width of the bending groove, and the distance between the side wall of the limiting plate 34 and the side wall of the bending groove is greater than the diameter of the wire harness. When the two auxiliary claws 5 are far apart to the limit state, the distance between the side wall of the auxiliary claw 5 and the side wall of the bending groove is slightly greater than the diameter of the wire harness.

[0031] In the implementation of this utility model: When the device is in its initial state, the transmission plate 25 abuts against the movable seat 2, the compression spring 24 is in its natural state, the movable magnet 33 cooperates with the fixed magnet 14 near the telescopic member 21, and the torsion spring is in its natural state. At this time, the user places the wire harness between the limiting plate 34 and the auxiliary claw 5 (the connectors at both ends of the wire harness are located on the opposite sides of the two auxiliary claws 5). Then, the telescopic member 21 is activated, driving the movable seat 2 to move towards the bending seat 11. Under the action of the fixed magnet 14... When the movable seat 2 moves relative to the driven plate 26 and the bearing seat 3, under the action of the adjusting rod 27, the two auxiliary claws 5 move away from each other. When the movable seat 2 abuts against the side plate 31, the movable seat 2 can drive the bearing seat 3 to move synchronously. The movable magnet 33 disengages from the fixed magnet 14 near the telescopic member 21. The movable seat 2 drives the bearing seat 3 to move synchronously. The end of the bearing seat 3 away from the movable seat 2 enters the bending groove. The side wall of the bending groove cooperates with the auxiliary claws 5 to bend the wire harness (the connection at both ends of the wire harness). (The head does not enter the bending groove, and the auxiliary seat 12 can provide a space for the joint.) At this time, the extension plate 32 abuts against the support 13 near the bending seat 11, the movable magnet 33 cooperates with the fixed magnet 14 away from the telescopic member 21, and then the telescopic member 21 drives the movable seat 2 to move away from the bending seat 11. Under the action of the fixed magnet 14, the movable seat 2 drives the driven plate 26 to move relative to the bearing seat 3, so that the two auxiliary claws 5 move closer to each other. When the transmission plate 25 abuts against the side plate 31, the movable seat 2 continues to move. The extension plate 32 moves the support 3 toward the telescopic member 21, causing the support 3 to reset. When the extension plate 32 abuts against the support 13 away from the bending seat 11, the moving magnet 33 cooperates with the fixed magnet 14 near the telescopic member 21. At this time, the moving seat 2 continues to move toward the telescopic member 21, causing the drive plate 8 and the support 3 to move relative to each other, thereby causing the push shaft 81 to push the telescopic shaft 62 to rotate. The telescopic shaft 62 automatically extends, and the lifting member 7 lifts the bent wire harness for easy removal by the user.

[0032] This utility model provides a wire harness bending fixture, which has the following advantages:

[0033] 1. By setting a movable auxiliary claw, it can not only ensure a good wire harness bending effect, but also automatically retract the wire harness after bending and shaping, making it convenient for users to pick up the wire and improving work efficiency. In addition, the position of the auxiliary claw can be automatically adjusted during the movement of the carrier, without the need for additional drive components, thus reducing manufacturing and usage costs.

[0034] 2. By setting up structures such as lifting components, drive plates, and push shafts, the wire harness can be automatically lifted after it is bent and formed and the device is reset, which further reduces the difficulty of wire picking operations and ensures good continuous operation efficiency.

[0035] In summary, the beneficial effects of this utility model are: it can automatically adjust the position of the auxiliary claw during the movement of the support seat to ensure a good wire harness bending effect, and it can automatically lift the wire harness after it is bent into shape, making it easier for the user to pick up the wire and improving the efficiency of continuous operation.

[0036] Of course, there may be many other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
