[0029] The specific embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the description of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] The directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the utility model.

[0032] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0033] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0034] See also Figure 1 , Figure 2 The embodiment of the utility model provides a pin bending device for bending the pin of a vehicle-mounted electromagnetic coil, and the pin bending device comprises a base 1 and a clamping mechanism 2 and a bending mechanism 3 mounted on the base 1. The electromagnetic coil mentioned here may refer to a coil in a suspension system of a car, specifically, a coil electrically connected to a PCB board of the suspension system.

[0035] In this embodiment, the clamping mechanism 2 includes a first driving member 21 and a clamping jaw 22, wherein the clamping jaw 22 is in transmission connection with the first driving member 21; the bending mechanism 3 includes a second driving member 31 and a roller 32, wherein the roller 32 is in transmission connection with the second driving member 31. The first driving member 21 and the second driving member 31 mentioned here can be pneumatic, electric or other power servo mechanisms, such as a cylinder, an electric cylinder, etc.

[0036] In this embodiment, the first driving member 21 is a cylinder, which is used to drive the clamping jaws 22 to open or close along a preset first direction to release or clamp the pin. The second driving member 31 is also a cylinder, which is used to drive the roller 32 to move along a second direction perpendicular to the first direction to bend the pin. It should be noted that the first direction mentioned here can refer to the length direction of the first driving member 21, or the direction perpendicular to the first direction. Figure 1 The second direction may refer to the length direction of the second driving member 31, or Figure 1 The left-right direction of the paper shown.

[0037] like Figure 4 , Figure 5 As shown, the clamping jaw 22 includes a clamping jaw body 22a and a protrusion 22b provided at one side of the bottom end of the clamping jaw body 22a, wherein the protrusion 22b protrudes and extends in a direction parallel to the width direction of the clamping jaw body 22a. It should be noted that, in order to ensure that the clamping jaw 22 stably clamps the pin after being closed under the drive of the first driving member 21, the protrusion 22b has a limiting surface 221 for limiting the pin in the second direction. Specifically, the limiting surface 221 is a side surface provided on the left side of the protrusion 22b. When the clamping jaw 22 clamps the pin in the vertical state in the initial state under the drive of the first driving member 21, since the limiting surface 221 and the bottom end side wall of the clamping jaw body 22a are at a right angle, under the limiting action of the limiting surface 221 and the bottom end side wall of the clamping jaw body 22a, it is beneficial to reliably clamp the pin so that the bending mechanism 3 can be bent.

[0038] Furthermore, since there are several pins on the electromagnetic coil, in order to ensure the consistency of the bending process, the protrusion 22b also has a support surface 222 intersecting with the limiting surface 221 for supporting the pin. Specifically, the support surface 222 is a top surface provided on the top of the protrusion 22b. When the clamping mechanism 2 clamps the pin, the limiting surface 221 abuts against the side wall of the pin, and the roller 32 moves along the second direction under the drive of the second driving member 31 to abut and bend the pin. Specifically, the roller 32 rolls along the length direction of the support surface 222.

[0039] Furthermore, in order to prevent the bending point of the pin from being damaged by the bending mechanism 3, the protrusion 22b is provided with a chamfer 223, which is provided between the limiting surface 221 and the supporting surface 222, so that the roller 32 can move above the supporting surface 222 with less resistance. Preferably, the radius of the chamfer 223 is 0.2 mm to 0.5 mm.

[0040] In some implementations, the number of the clamping jaws 22 may be multiple. In this embodiment, the number of the clamping jaws 22 is two, so as to better clamp the pins that are initially in a vertical state.

[0041] Since the pin is usually made of metal, when the pin is bent, springback occurs, so that the bending angle of the pin does not meet the expected process requirements. In this embodiment, Figure 2 , Figure 3 As shown, in order to prevent the pin from having a large error in the bending angle due to rebound, the bending mechanism 3 also includes a fixing plate 33 connected between the base 1 and the second driving member 31. It should be noted that the fixing plate 33 is wedge-shaped. Preferably, the angle between the fixing plate 33 and the ground is 2 to 5 degrees, and the fixing plate 33 is inclined along the upper left side of the horizontal ground, so as to better compensate for the rebound angle of the pin after bending.

[0042] Furthermore, the bending mechanism 3 further includes a connecting plate 34 connected between the second driving member 31 and the roller 32, and the roller 32 is hinged at one end of the connecting plate 34. It should be noted that, for the purpose of weight reduction, a first weight reduction hole 341 is provided in the middle of the connecting plate 34. In some embodiments, the shape of the first weight reduction hole 341 may be a rectangular hole or a trapezoidal hole. In this embodiment, the shape of the first weight reduction hole 341 is a diamond hole.

[0043] In this embodiment, if Figure 2As shown, the base 1 is a frame structure, and second weight-reducing holes 11 are provided on both sides of the base 1 to further reduce the weight of the pin bending device. It should be noted that, in order to ensure the compact structure of the pin bending device, the clamping mechanism 2 and the bending mechanism 3 are respectively installed on both sides of the base 1. Specifically, the clamping mechanism 2 is fixedly connected to the top of the base 1, and the bending mechanism 3 is fixedly connected to the bottom of the base 1. That is to say, in the vertical direction, the base 1 is arranged between the clamping mechanism 2 and the bending mechanism 3. This arrangement not only makes the pin bending device compact and occupies a small space, but also helps to avoid interference between the clamping mechanism 2 and the bending mechanism 3 in movement.

[0044] By adopting the above technical solution, the utility model has the following beneficial effects:

[0045] The utility model discloses a pin bending device, which is used for bending the pin of a vehicle-mounted electromagnetic coil, and comprises a base 1, a clamping mechanism 2 and a bending mechanism 3 mounted on the base 1, wherein the clamping mechanism 2 comprises a first driving member 21 and a clamping jaw 22 connected to the first driving member 21, the first driving member 21 is used to drive the clamping jaw 22 to open or close along a preset first direction to release or clamp the pin; the bending mechanism 3 comprises a second driving member 31 and a roller 32 connected to the second driving member 31, the second driving member 31 is used to drive the roller 32 to move along a second direction perpendicular to the first direction to bend the pin. Compared with the prior art, the utility model can not only meet the assembly process requirements of continuous production, but also help to ensure the consistency of the bending angle of the pin by setting a protrusion 22b on the clamping jaw 22 for limiting and supporting the pin.

[0046] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
