[0044] It can be understood that the first clamping jaw 2 and the second clamping jaw 3 are both slidably connected to the mounting plate 1, the first direction is perpendicular to the length direction of the bus duct copper bar automatic bending machine, and the second direction is parallel to the length direction of the bus duct copper bar automatic bending machine.

[0045] When the servo clamp device in the present application is used to clamp the copper busbar, the first servo motor 41 is started, and then the first servo motor 41 drives the first transmission structure 42, so that the first clamping jaw 2 and the second clamping jaw 3 move in the first direction toward each other under the action of the first transmission structure 42 and finally respectively contact the opposite sides of the copper busbar to achieve clamping of the copper busbar; and when the copper busbar is transported back and forth, the second servo motor 51 is started, and the second servo motor 51 drives the second transmission structure 52, so that the mounting plate 1 moves in the second direction under the action of the second transmission structure 52 to achieve forward and backward transportation of the copper busbar.

[0046] Since the servo clamp device in the present application is driven by a servo motor, compared with the driving method of a cylinder or a hydraulic cylinder, the accuracy of the movement position of the first clamp 2 and the second clamp 3 is greatly improved, and the response efficiency of the first clamp 2 and the second clamp 3 when clamping or releasing the copper busbar is improved, thereby greatly improving the operating speed of the servo clamp device and increasing the stability of the servo clamp device during operation.

[0047] Moreover, when clamping copper bars of different specifications, the servo clamp device in the present application can flexibly adjust the clamping force of the first clamping jaw 2 and the second clamping jaw 3 on the copper bar by adjusting the parameters of the servo motor. The force adjustment is more accurate, convenient and quick than the hydraulic or pneumatic system, so as to greatly reduce the risk of clamping marks when clamping the copper bar. In addition, the mounting plate 1 is also driven by a servo motor. Compared with conventional power devices, it has the advantages of high precision, overloadability, closed-loop feedback, torque control, stable performance, and constant torque output.

[0048] The present application does not specifically limit the structure of the first transmission structure 42. Preferably, refer to Figure 1 、 Figure 2 and Figure 3 The first transmission structure 42 includes a first transmission shaft 421 rotatably connected to the mounting plate 1, a first transmission block 422 threadedly connected to the first transmission shaft 421, and a second transmission block 423 threadedly connected to the first transmission shaft 421. When the first transmission shaft 421 rotates, the first transmission block 422 and the second transmission block 423 move in a direction approaching or moving away from each other, the first clamping jaw 2 is connected to the first transmission block 422, and the second clamping jaw 3 is connected to the second transmission block 423.

[0049] It can be understood that both ends of the first transmission shaft 421 are rotatably connected to the mounting plate 1 through the shaft seat, the first transmission shaft 421 is arranged parallel to the first direction, and the first transmission shaft 421 is provided with two sections of external threads in opposite directions along its length direction. The first transmission block 422 and the second transmission block 423 are respectively threadedly connected to the two sections of external threads in opposite directions, so that when the first transmission shaft 421 rotates, the first transmission block 422 and the second transmission block 423 move along the axial direction of the first transmission shaft 421 toward or away from each other.

[0050] When clamping the copper busbar, the first servo motor 41 is started, and the first servo motor 41 drives the first transmission shaft 421 to rotate, thereby causing the first transmission shaft 421 and the first transmission block 422 and the second transmission block 423 to rotate relative to each other. At the same time, the first transmission block 422 and the second transmission block 423 move toward each other along the axial direction of the first transmission shaft 421, so that the first clamping jaw 2 and the second clamping jaw 3 move toward each other, thereby realizing the driving of the first transmission structure 42 on the first clamping jaw 2 and the second clamping jaw 3; and when releasing the clamping of the copper busbar by the first clamping jaw 2 and the second clamping jaw 3, the second servo motor 51 can rotate in the opposite direction.

[0051] The present application does not specifically limit the transmission connection method between the first transmission shaft 421 and the first servo motor 41. Preferably, one end of the first transmission shaft 421 is transmission-connected to the output shaft of the first servo motor 41 via a reducer. In other embodiments, the first transmission shaft 421 may also be transmission-connected to the output shaft of the first servo motor 41 via a coupling.

[0052] Further, refer to Figure 1 、 Figure 2 and Figure 3 The first transmission block 422 is provided with a first connecting plate 11 slidingly connected to the mounting plate 1, and the first clamping jaw 2 is connected to the first connecting plate 11, which can increase the stability of the first clamping jaw 2 and reduce the burden of the first transmission block 422 to ensure the transmission accuracy between the first transmission block 422 and the first transmission shaft 421; the second transmission block 423 is provided with a second connecting plate 12 slidingly connected to the mounting plate 1, and the second clamping jaw 3 is connected to the second connecting plate 12, which can increase the stability of the second clamping jaw 3 and reduce the burden of the second transmission block 423 to ensure the transmission accuracy between the second transmission block 423 and the second transmission shaft 521.

[0053] Further, refer to Figure 1 、 Figure 2 and Figure 3 The mounting plate 1 is provided with first slide rails 13 located on both sides of the first transmission shaft 421, and the first connecting plate 11 and the second connecting plate 12 are both provided with first sliders 111 that slide with the first slide rails.

[0054] It can be understood that the first slide rail 13 is arranged parallel to the first direction, and there are two first slide rails 13. The first connecting plate 11 and the second connecting plate 12 are each provided with at least two first sliders 111 corresponding to the slide rails, and each first slider 111 is slidably engaged with the corresponding first slide rail 13.

[0055] When the first clamping jaw 2 and the second clamping jaw 3 are driven, the first slider 111 and the first slide rail 13 slide relative to each other, and the sliding cooperation between the first slider 111 and the first slide rail 13 guides the movement of the first clamping jaw 2 and the second clamping jaw 3 to increase the stability of the first clamping jaw 2 and the second clamping jaw 3 during movement; at the same time, since the first slide rail 13 is located on both sides of the first transmission shaft 421, the first slider 111 is also located on both sides of the first transmission shaft 421, so that the first connecting plate 11 and the second connecting plate 12 are balanced in force to increase the stability of the first clamping jaw 2 and the second clamping jaw 3.

[0056] The present application does not specifically limit the connection method between the first clamping jaw 2 and the first connecting plate 11 and the connection method between the second clamping jaw 3 and the second connecting plate 12. Preferably, refer to Figure 1 、 Figure 2 and Figure 3 The first clamping jaw 2 is provided with a first positioning rib 21, and the first connecting plate 11 is provided with a first positioning groove 112 for accommodating the first positioning rib 21; the second clamping jaw 3 is provided with a second positioning rib 31, and the second connecting plate 12 is provided with a second positioning groove 121 for accommodating the second positioning rib 31.

[0057] It can be understood that the first clamping jaw 2 is fixedly connected to the first connecting plate 11 by a bolt pair so that the relative position of the first clamping jaw 2 and the first connecting plate 11 can be adjusted, and the second clamping jaw 3 is also fixedly connected to the second connecting plate 12 by a bolt pair so that the relative position of the second clamping jaw 3 and the second connecting plate 12 can be adjusted.

[0058] That is to say, the first positioning rib 21 is located in the first positioning groove 112, so that the cooperation between the first positioning rib 21 and the first positioning groove 112 can position the first clamping jaw 2, which can increase the connection stability between the first clamping jaw 2 and the first connecting plate 11 on the one hand, and increase the efficiency when assembling the first clamping jaw 2 to the first connecting plate 11 on the other hand; the second positioning rib 31 is located in the second positioning groove 121, so that the cooperation between the second positioning rib 31 and the second positioning groove 121 can position the second clamping jaw 3, which can increase the connection stability between the second clamping jaw 3 and the second connecting plate 12 on the one hand, and increase the efficiency when assembling the second clamping jaw 3 to the second connecting plate 12 on the other hand.

[0059] Further, refer to Figure 1 and Figure 3The first clamping jaw 2 has a first limiting rib 22 that abuts against the end of the first connecting plate 11, which on the one hand increases the positioning effect of the first clamping jaw 2, and on the other hand can also increase the connection stability of the first clamping jaw 2 and the first connecting plate 11; the second clamping jaw 3 has a second limiting rib 32 that abuts against the end of the second connecting plate 12, which on the one hand increases the positioning effect of the second clamping jaw 3, and on the other hand can also increase the connection stability of the second clamping jaw 3 and the second connecting plate 12.

[0060] In other implementation examples, the first clamping jaw 2 may also be integrally formed on the first connecting plate 11 , and the second clamping jaw 3 may also be integrally formed on the second connecting plate 12 .

[0061] In a preferred embodiment, referring to Figure 1 and Figure 2 The mounting plate 1 is provided with an avoidance opening 14 corresponding to the first transmission block 422 and the second transmission block 423. At least part of the first transmission block 422 and the second transmission block 423 extends into the avoidance opening 14, so that the first transmission block 422 and the second transmission block 423 can form an avoidance with the mounting plate 1, thereby greatly reducing the volume of the servo clamp device so as to miniaturize the servo clamp device.

[0062] It can be understood that the first transmission shaft 421, the first transmission block 422 and the second transmission block 423 are all located at the bottom of the mounting plate 1, so that the first clamping jaw 2 and the second clamping jaw 3 can avoid the mounting plate 1, thereby reducing the thickness of the first clamping jaw 2 and the second clamping jaw 3 and reducing the production cost of the first clamping jaw 2 and the second clamping jaw 3.

[0063] In other embodiments, the first transmission structure 42 can also be a matching structure of a gear and a rack, that is, a gear is provided and is coaxially fixedly connected to the output shaft of the first servo motor 41, two racks are provided and both are meshed and connected to the gear, and the two racks are respectively connected to the first clamp 2 and the second clamp 3.

[0066] When driving the mounting plate 1, the second servo motor 51 is started, and the second servo motor 51 drives the second transmission shaft 521, thereby causing the second transmission shaft 521 and the driving block 522 to rotate relative to each other, so that the driving block 522 moves along the axial direction of the second transmission shaft 521, thereby causing the driving block 522 to drive the mounting plate 1 to move, thereby driving the mounting plate 1.

[0067] Further, refer to Figure 1 and Figure 2 A driving plate 15 is extended from the side of the mounting plate 1 , and the driving block 522 is connected to the driving plate 15 , thereby increasing the distance between the second transmission shaft 521 and the mounting plate 1 to ensure the movement stroke of the mounting plate 1 .

[0068] Preferably, the second transmission shaft 521 is connected to the output shaft of the second servo motor 51 through a connector or a reducer.

[0069] Both ends of the second transmission shaft 521 are also provided with shaft seats, which are fixedly connected to the frame of the busbar copper bar automatic bending machine to increase the stability of the second transmission shaft 521.
