[0036] The first driving assembly 4 includes a moving seat 41, and the moving seat 41 is movably arranged on the slide 3; specifically, two guide rods are provided on the slide 3, and the guide rods penetrate the moving seat 41, and the moving seat 41 is provided with two through-hole structures adapted to the guide rods; a motor and a screw rod are provided on the slide 3, and the motor is fixedly connected to the screw rod, and the screw rod is rotatably arranged on the slide 3 through a bearing, and the screw rod is threadedly connected to the moving seat 41, and the screw rod and the moving seat 41 are both arranged horizontally, and the moving seat 41 can be driven to move horizontally by the motor, and the motor drives the support seat 2 to move in a direction perpendicular to the moving direction of the slide 3; the above are all existing technologies and will not be repeated here. The position adjustment of the moving seat 41 can be achieved through the above arrangement, that is, the position of the grooving blade 8 can be adjusted.

[0037] Two guide rails 44 are provided on the moving seat 41, and the two guide rails 44 are both vertically arranged; each guide rail 44 is provided with a guide slider 45, and the guide slider 45 is fixedly connected to the support seat 2; the first drive assembly 4 also includes a first drive motor 42 and a first screw 43, the first drive motor 42 is installed on the moving seat 41, the first screw 43 is movably arranged on the moving seat 41 through a bearing, and the output end of the first drive motor 42 is fixedly connected to the first screw 43, the first screw 43 passes through the support seat 2, and the first screw 43 is threadedly connected to the support seat 2; that is, the first screw 43 is driven to rotate by the first drive motor 42, and with the cooperation of the guide slider 45 and the guide pulley 2 712, the support seat 2 can be driven up and down, thereby driving the tool holder 1 6, the tool holder 2 7 and the grooving blade 8 to move up and down.

[0038] The lifting assembly 53 is used to drive the first guide rail 51 and the second guide rail 52 to rise and fall synchronously, and the first guide rail 51 and the second guide rail 52 are both connected to the lifting assembly 53; in this embodiment, when the first drive motor 42 drives the support base 2 to descend, the lifting assembly 53 also drives the first guide rail 51 and the second guide rail 52 to descend, and makes the descending displacement of the support base 2 consistent with the descending displacement of the first guide rail 51 and the second guide rail 52; and when the first drive motor 42 drives the support base 2 to rise, the lifting assembly 53 also drives the first guide rail 51 and the second guide rail 52 to rise, and makes the ascending displacement of the support base 2 consistent with the ascending displacement of the first guide rail 51 and the second guide rail 52; the first drive motor 42 can first drive the support base 2 to rise and fall, and then the lifting assembly 53 drives the first guide rail 51 and the second guide rail 52 to rise and fall.

[0039] When the electric vehicle is grooving the joint plate, the guide pulley 1 612 cooperates with the horizontal section 1 511, and the guide pulley 2 712 cooperates with the horizontal section 3 521, that is, Figure 1 The state shown; by placing the electric vehicle coupling plate to be grooved on the frame 1, a clamping device for clamping the electric vehicle coupling plate can be provided on the frame 1. The clamping device adopts the existing device and will not be described in detail. For example, a screw slider mechanism is used in conjunction with a clamping plate to clamp the metal; thereafter, the movable seat 41 is adjusted to a suitable position so that the grooved blade 8 corresponds to the position of the electric vehicle coupling plate to be grooved; subsequently, the first drive motor 42 is used to drive the support frame 91 to drop a suitable distance, that is, the grooved blade 8 on the tool holder 6 drops a suitable distance, and at the same time, the lifting assembly 53 drives the first guide rail 51 and the second guide rail 52 to drop the same distance synchronously; then, the movable seat 41 is moved to drive the movable seat 41, the support seat 2, etc. to move, so that the grooved blade 8 on the tool holder 6 can be driven to plane the electric vehicle coupling plate. The grooved blade 8 is arranged at two intervals to plane the electric vehicle coupling plate, which helps to ensure the planing quality.

[0040] When the guide pulley 1 612 moves to cooperate with the horizontal end 2, and the guide pulley 2 712 cooperates with the horizontal end 4, at this time, the bottom end of the corresponding grooving blade 8 on the first tool holder is higher than the bottom end of the corresponding grooving blade 8 on the first tool holder. Since the descending distance of the support frame 91 is consistent with the descending distance of the first guide rail 51 and the second guide rail 52, the grooving blade 8 on the tool holder 2 7 will replace the grooving blade 8 on the tool holder 1 6 to continue to plane the electric vehicle coupling plate until the grooving blade 8 on the tool holder 2 7 has planed the remaining parts, and the first planing can be achieved; therefore, during the planing process, the grooving blades 8 on the tool holder 1 6 and the tool holder 2 7 alternately plan the electric vehicle coupling plate, avoiding the same grooving blade 8 continuously planing the electric vehicle coupling plate during the planing process, which helps to reduce or avoid deformation of the grooving blade 8 due to overheating, and helps to ensure that the grooving blade 8 is planing stably.

[0041] After the planing blades 8 on the tool holder 1 6 and the tool holder 2 7 have alternately planed one continuous operation, that is, after the planing blades 8 on the tool holder 1 6 and the tool holder 2 7 have completely passed through the surface of the electric vehicle coupling plate from the start of planing to the planing blades 8 on the tool holder 2 7, the first drive motor 42 drives the support base 2 to reset, and then the lifting assembly 53 drives the first guide rail 51 and the second guide rail 52 to reset; then the slide 3 is reset, and at this time the support base 2, the first guide rail 51, the second guide rail 52, the tool holder 1 6, etc. are reset to the initial state, that is, Figure 1 In the state shown, the first driving motor 42 drives the support seat 2 to descend, and the lifting component 53 drives the first guide rail 51 to descend. The descending distance of the first guide rail 51 is consistent with the descending distance of the support seat 2. At this time, the descending distance of the support seat 2 is greater than the descending distance of the support seat 2 during the first planing. Through the above-mentioned operation, the slide 3 drives the support seat 2 to move, and the planing depth is deepened; the operation is repeated until the required planing requirement is reached; after the planing is completed, the slide 3, the support seat 2, the first guide rail 51, the second guide rail 52, etc. are reset to Figure 1 After the groove is completed, the electric vehicle connecting plate can be taken out.

[0042] Example 2

[0043] See also Figure 1-Figure 7 This embodiment is based on the first embodiment. The lifting assembly 53 includes a first carrier 531 and a second carrier 532. The first carrier 531 and the second carrier 532 can be movably set on the frame 1, and the first carrier 531 and the second carrier 532 can move up and down; specifically, the first carrier 531 and the second carrier 532 can be movably set on the frame 1 through linear guide rails.

[0044] The lifting assembly 53 also includes a second drive motor 533 and a second screw 534. The second drive motor 533 is installed on the frame 1. The second screw 534 is movably set on the frame 1 through a bearing, and the output end of the second drive motor 533 is fixedly connected to the upper end of the second screw 534; at the same time, the second screw 534 passes through the second supporting frame 532, and the second screw 534 is threadedly connected to the second supporting frame 532; by driving the second screw 534 to rotate by the second drive motor 533, the first supporting frame 531 and the second supporting frame 532 can be driven to move up and down, thereby realizing the up and down lifting of the first guide rail 51 and the second guide rail 52.

[0045] Example 3

[0046] See also Figure 7 This embodiment is based on the second embodiment, and a notch is provided on the slide 3, and the second carrier 532 passes through the notch. By providing the notch, the second carrier 532 is prevented from interfering with the slide 3 when the second carrier 532 moves up and down.
