[0053] like Figure 3 and Figure 4 As shown, in some embodiments, the support member 32 includes a first support rod 321 and a second support rod 322; the first support rod 321 is arranged along the vertical direction C, the second support rod 322 extends along the second direction B perpendicular to the first direction A and is fixedly connected to the first support rod 321, and the end of the second support rod 322 away from the first support rod 321 is connected to a guide block 3221, and the guide block 3221 is provided with a second through hole 3222 along the vertical direction C, and the punching rod 33 passes through the second through hole 3222 to be slidably connected to the guide block 3221; an elastic member 34 is arranged between the guide block 3221 and the force-bearing plate body 331, and the driving assembly 5 drives the force-bearing plate body 331, the elastic member 34 generates an elastic force, and drives the punching rod 33 to reset along the vertical direction C under the action of the elastic force.

[0054] Specifically, in order to support the punching rod 33, the present application is provided with a first support rod 321 and a second support rod 322. The first support rod 321 is arranged along the vertical direction C and is separated by the through slot 11. The second support rod 322 extends along the second direction B perpendicular to the first direction A and is fixedly connected to the first support rod 321. The second support rod 322 provides support between the punching rod 33 and the first support rod 321 and enables the position of the punching rod 33 to correspond to the setting position of the through slot 11 so that the punching end 311 on the punching head 31 can match the first through hole 21 on the mold 2. In order to guide the reciprocating motion of the punching rod 33 along the vertical direction C, the present application connects a guide block 3221 to the end of the second support rod 322 away from the first support rod 321. The guide block 3221 is provided with a second through hole 3222 along the vertical direction C, so that the punching rod 33 can pass through the second through hole 3222 and be slidably connected to the guide block 3221.

[0055] In order to generate elastic force between the guide block 3221 and the force plate 331, and drive the punching rod 33 to reset along the vertical direction C under the action of the elastic force, the present application sets an elastic member 34 between the guide block 3221 and the force plate 331. Since the position of the guide block 3221 is fixed, when the force plate 331 reciprocates in the vertical direction C under the action of the driving assembly 5, the elastic member 34 generates elastic force during the stretching and compression process to drive the punching rod 33 to reset. The elastic member 34 can be a coil spring, polyurethane elastomer, rubber, etc., which is sleeved on the punching rod 33 between the guide block 3221 and the force plate 331; it can also be a leaf spring, with both ends connected to the force plate 331 and the punching rod 33 below it. There is no specific limitation, as long as elastic reset can be achieved.

[0056] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the driving assembly 5 includes a first transmission assembly 51 and a second transmission assembly 52; the first end of the first transmission assembly 51 is arranged on the base 1 with the through groove 11 and the first support rod 321, and the second end is rotatably connected to the first support rod 321 above the second support rod 322 and the rotation axis is parallel to the second direction B; the second transmission assembly 52 and the first transmission assembly 51 are coaxially connected on both sides of the first support rod 321 respectively, and the second transmission assembly 52 is located above the force-bearing plate body 331, and the second transmission assembly 52 is away from the rotation connection position of the first transmission assembly 51 and the first support rod 321 and has a driving end, and the driving end can resist the force-bearing plate body 331; wherein, the first transmission assembly 51 drives the second transmission assembly 52 to rotate relative to the first support rod 321, and the driving end reciprocates to drive the punching end 311 of the punching head 31 to approach or move away from the first through hole 21.

[0057] Specifically, in order to realize the driving assembly 5 to drive the force-bearing plate body 331 at one end of the T-shaped punching rod 33, the driving assembly 5 of the present application includes a first transmission assembly 51 and a second transmission assembly 52. Through the coordinated transmission between the two-stage transmission assemblies, the punching auxiliary tool of the present application can have a larger transmission ratio and better torque distribution during the punching operation, thereby improving work efficiency and ensuring stable operation. The first end of the first transmission assembly 51 is arranged on the base 1 with the spacing slot 11 and the first support rod 321, and the second end is rotatably connected to the first support rod 321 above the second support rod 322, and the rotation axis is parallel to the second direction B, so as to be able to drive the force-bearing plate body 331 above the second support rod 322. The second transmission assembly 52 is coaxially connected with the first transmission assembly 51 on both sides of the first support rod 321 respectively. The shaft can be a spline shaft or a stepped shaft, etc., without limitation, to realize energy transmission from the first transmission assembly 51 to the second transmission assembly 52. The second transmission assembly 52 is located above the force-bearing plate body 331. The second transmission assembly 52 is away from the rotational connection position of the first transmission assembly 51 and the first support rod 321 and has a driving end so that the force-bearing plate body 331 can be supported by the driving end. When the first transmission assembly 51 drives the second transmission assembly 52 to rotate relative to the first support rod 321, the driving end reciprocates to drive the punching end 311 of the punching head 31 to approach or move away from the first through hole 21, thereby realizing the punching operation of the part to be punched in the accommodating space 4.

[0058] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the first transmission assembly 51 includes a driving motor 511, a driving gear 512 and a driven gear 513. The driving motor 511 is arranged on the base 1 with the spacing slot 11 and the first support rod 321. The driving gear 512 is connected to the output end of the driving motor 511. The driven gear 513 engages with the driving gear 512 and is rotationally connected to the first support rod 321, and the rotational connection position is located above the second support rod 322.

[0059] Specifically, since the gear transmission has a high transmission efficiency, in order to ensure the effective transmission of the torque output by the driving motor 511, the first transmission component of the present application includes a driving motor 511, a driving gear 512 and a driven gear 513. The driving motor 511 is arranged on the base 1 with an interval slot 11 and a first support rod 321. The driving gear 512 is connected to the output end of the driving motor 511. The driven gear 513 engages with the driving gear 512 and is rotationally connected to the first support rod 321, and the rotational connection position is located above the second support rod 322. By adjusting the ratio of the number of teeth of the driving gear 512 and the driven gear 513, the speed and torque of the output shaft can be controlled, thereby achieving stable and reliable transmission requirements.

[0060] like Figure 1 , Figure 2and Figure 3 As shown, in some embodiments, the radius of the driven gear 513 is greater than that of the driving gear 512.

[0061] Specifically, in this application, the radius of the driven gear 513 is set to be greater than that of the driving gear 512, so that the driven gear 513 can have a larger torque and a lower rotational speed. The larger torque can provide the transmission capacity of the first transmission component 51, reduce the energy consumption during the transmission from the first transmission component 51 to the second transmission component 52, and improve the efficiency. The lower rotational speed can reduce the noise during the punching operation of the punching auxiliary tool, and at the same time better control the punching operation cycle to ensure the stable and safe punching operation.

[0062] As Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the second transmission component 52 includes an eccentric swing arm 521 and a driving member 522. The first end of the eccentric swing arm 521 is coaxially connected to the driven gear 513 and is rotatably connected to the first support rod 321. The second end of the eccentric swing arm 521 away from the rotation connection position is the driving end, and the driving member 522 is connected to the driving end along the second direction B.

[0063] Specifically, in order to enable the second transmission component 52 to generate a reciprocating and stable motion trajectory to drive the force-bearing plate 331 under the drive of the first transmission component 51, the second transmission component 52 of this application includes an eccentric swing arm 521 and a driving member 522. The first end of the eccentric swing arm 521 is coaxially connected to the driven gear 513 and is rotatably connected to the first support rod 321 to utilize the rotation of the eccentric shaft at the rotation connection position of the eccentric swing arm 521 to realize the swinging motion of the second end of the eccentric swing arm 521, so as to realize a reciprocating and stable swinging trajectory. The second end of the eccentric swing arm 521 away from the rotation connection position is the driving end, and the driving member 522 is connected to the driving end along the second direction B, so as to be able to abut against the force-bearing plate 331 to move reciprocally in the vertical direction C through the driving member 522 during the reciprocating swing of the eccentric swing arm 521 to complete punching.

[0064] As Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the driving member 522 is in the shape of a long rod. A bearing 5221 is sleeved on the end of the long rod-shaped driving member 522 away from the eccentric swing arm 521, and the bearing 5221 is arranged above the force-bearing plate 331 for abutting against the force-bearing plate 331.

[0065] Specifically, during the process of the eccentric swing arm 521 making a circular motion driven by the first transmission assembly 51, the driving member 522 connected to the second end of the eccentric swing arm 521 away from the rotational connection position drives the punching head 31 on the punching rod 33 to perform a punching operation in the vertical direction C through abutting against the force-bearing plate body 331. In this application, a long rod-shaped driving member 522 is provided. In order to reduce the friction between the driving member 522 and the surface of the force-bearing plate body 331 during the abutting process, a bearing 5221 is sleeved on one end of the long rod-shaped driving member 522 away from the eccentric swing arm 521. During the process of the bearing 5221 abutting against the force-bearing plate body 331 driven by the driving member 522, it can rotate itself during the circular motion following the eccentric swing arm 521, and thus the friction with the surface of the force-bearing plate body 331 is rolling friction, so that the friction force is relatively small.

[0066] As Figure 1 , Figure 2 and Figure 3 shown, in some embodiments, the drive assembly 5 further includes a motor controller 53 and a storage battery 54. The motor controller and the storage battery 54 are arranged on the base 1, and the storage battery 54 and the drive motor 511 are respectively connected to the motor controller 53.

[0067] Specifically, in order to control the rotation speed and transmission torque of the drive motor 511, this application also provides a motor controller 53. Under the control of the motor controller 53, the rotation speed and transmission torque of the driven motor are adjustable, which in turn affects the rotation speeds of the driving gear 512, the driven gear 513, and the eccentric swing arm 521, and further affects the motion period of the driving member 522 connected to the second end of the eccentric swing arm 521 for abutting against the force-bearing plate body 331, so that the punching efficiency of the punching auxiliary tool in this application is adjustable. The storage battery 54 and the drive motor 511 are respectively connected to the motor controller 53 to provide the required voltage and current for the operation of the motor controller 53 and the drive motor 511 through the storage battery 54, ensuring the normal and stable operation of the drive motor 511.

[0068] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
