[0025] A base frame 1 and a pair of grooves 2, wherein clamping assemblies 7 are arranged in the grooves 2;

[0026] A transverse lead screw 3 and a transverse slide rail 4, wherein the transverse lead screw 3 and the transverse slide rail 4 are both arranged between the inner and outer surfaces of the base frame 1, and the transverse lead screw 3 is driven to rotate by a motor;

[0027] The movable frame 5 is slidably connected in the transverse slide rail 4, and the movable frame 5 is connected to the transverse lead screw 3 through threaded matching;

[0028] The positioning punching assembly 6 is arranged outside the mobile frame 5. The positioning punching assembly 6 includes a plurality of supporting wheels 6-1, and the supporting wheels 6-1 are rotatably connected to the surface of the mobile frame 5. The surface of the mobile frame 5 is provided with a through hole 6-2, and a vertical screw 6-3 is rotatably connected to the through hole 6-2. The vertical screw 6-3 is driven to rotate by a motor, and a round rod 6-4 is arranged in the through hole 6-2. A moving seat 6-5 is slidably connected to the outside of the round rod 6-4. The moving seat 6-5 is connected to the vertical screw 6-3 through a threaded fit.

[0029] In this embodiment, in order to achieve a full-scale positioning and punching effect on the side piece, a positioning and punching assembly 6 is designed. A support wheel 6-1 is arranged inside the movable frame 5. The support wheel 6-1 is used to support the bottom surface of the side piece. When the movable frame 5 moves horizontally, it has a sliding and fitting effect with the side piece. The movement in the X-axis direction is controlled by the horizontal screw 3. A vertical screw 6-3 is installed in the movable frame 5. The outside of the vertical screw 6-3 is connected to a movable seat 6-5. The vertical screw 6-3 controls the movable seat 6-5 to move in the Y-axis direction, and can quickly position to the punching position. A punching hydraulic 6-6 is installed in the movable seat 6-5, and a long groove 6-7 is opened on the surface of the movable frame 5 relative to it, so as to cooperate with the punching hydraulic 6-6 to pass through the side piece.

[0030] Furthermore, the clamping assembly 7 includes a pair of cross bars 7-1, which are fixed in the groove 2. The outside of the cross bar 7-1 is slidably connected to the limit seat 7-2, and the outside of the cross bar 7-1 is sleeved with a support spring 7-3. The surface of the limit seat 7-2 is fixedly connected to an extension column 7-4, and the side end surface of the extension column 7-4 is provided with a slot 7-5.

[0031] In the present embodiment, in order to achieve the effect of fast and firm clamping of side panels of different lengths, a clamping assembly 7 is designed, a cross bar 7-1 is arranged in the groove 2, the outer sliding connection of the cross bar 7-1 is connected to a limit seat 7-2, an extension column 7-4 is arranged on the surface of the limit seat 7-2, a card slot 7-5 is provided on the end face of the extension column 7-4, the card slot 7-5 is used to insert the side panel, the limit seat 7-2 can move on the surface of the cross bar 7-1 according to the length, and a support spring 7-3 is mounted on the surface of the cross bar 7-1, which pushes the limit seat 7-2 through the elastic force, so that the extension columns 7-4 at both ends cooperate with the long groove 6-7 to clamp the side panel.

[0032] Furthermore, the slot 7-5 is in a V-shaped structure, and the end surface of the extension column 7-4 is an inclined structural surface.

[0033] In this embodiment, the V-shaped opening structure allows the side piece to be more accurately inserted into the card slot 7 - 5 .

[0034] Furthermore, both sides of the movable frame 5 are open U-shaped structures.

[0035] In this embodiment, the U-shaped structure enables the movable frame 5 to simultaneously play the role of supporting and punching.

[0036] Furthermore, a plurality of support wheels 6 - 1 are evenly arranged in a straight line and located on both sides of the long groove 6 - 7 .

[0037] In this embodiment, a plurality of support wheels 6 - 1 are evenly arranged in a straight line to increase the support points between the side panels, thereby preventing the side panels from being deformed during punching.

[0038] Furthermore, the punching hydraulic 6-6 is located directly above the long slot 6-7, and the opening size of the long slot 6-7 is larger than the maximum diameter size of the output end of the punching hydraulic 6-6.

[0039] In this embodiment, through the cooperation between the long groove 6-7 and the punching hydraulic 6-6, the punching hydraulic 6-6 can enter the long groove 6-7 when passing through the side plate, avoiding the surface of the movable frame 5 from affecting the punching, making the spacing of the support wheels 6-1 as small as possible, and making the support of the support wheels 6-1 to the side plate more stable.

[0040] When punching is required, the side piece is inserted horizontally into the slot 7-5 of the extension column 7-4. After insertion, the extension column 7-4 is pushed to both sides. The limit seat 7-2 at the bottom slides on the surface of the cross bar 7-1 and is pushed by the elastic force of the support spring 7-3, so that the extension column 7-4 clamps the side piece and fixes it. The bottom surface of the side piece fits against the upper end surface of the support wheel 6-1. Then the vertical screw 6-3 and the horizontal screw 3 are started, the moving seat 6-5 is quickly adjusted, the punching hydraulic 6-6 is positioned to the punching position, and then the punching hydraulic 6-6 is started to pass through the side piece. After all the holes are processed, the side piece can be directly pulled out.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
