[0028] As Figures 1-4As shown in the figure, an embodiment of the present utility model provides a steel plate cutting machine, which includes a frame 100, a mounting frame 110 provided on the frame 100, a cutting assembly 120 provided on the mounting frame 110, and a workbench 130 slidably provided on the frame 100. The steel plate cutting machine further includes two sets of fixing assemblies 200 for fixing the steel plate. The two sets of fixing assemblies 200 are symmetrically arranged at both ends of the workbench 130 respectively. Each set of fixing assemblies 200 includes two L-shaped plates 210 arranged oppositely on the workbench 130, a connecting rod 220 slidably arranged on the opposite sides of the two L-shaped plates 210, a bottom plate 230 provided on the L-shaped plate 210, a pressing plate 240 provided on the connecting rod 220 corresponding to the bottom plate 230, and an electric telescopic rod 250. The electric telescopic rod 250 is provided on the L-shaped plate 210, and its telescopic end is connected to the connecting rod 220 to drive it to move in the vertical direction, thereby driving the pressing plate 240 to move towards the bottom plate 230 to clamp the steel plate. The cutting assembly 120 is a conventional device in the art, and its specific structure will not be elaborated here.

[0029] In the embodiment of the present utility model, when it is necessary to cut the steel plate, first place the steel plate on the two bottom plates 230. Then, according to the length of the steel plate to be cut, expose the part to be cut out of the width of the bottom plate 230, and drive the connecting rod 220 to move downward through the electric telescopic rod 250. The downward movement of the connecting rod 220 can drive the pressing plate 240 to move downward, thereby increasing the distance between the pressing plate 240 and the bottom plate 230 to adapt to the thickness of the steel plate, reducing the labor intensity of the operator. Subsequently, by moving the workbench 130, the steel plate is cut under the action of the cutting assembly 120, thereby improving the efficiency of cutting the steel plate.

[0030] Specifically, as Figure 5 shown, in the embodiment of the present utility model, the pressing plate 240 is arranged on the connecting rod 220 through an elastic telescopic member 300. The elastic telescopic member 300 includes a plurality of positioning rods 310 arranged at intervals on the connecting rod 220 and slidable in the vertical direction, a mounting plate 320 connecting the bottoms of the plurality of positioning rods 310, and a plurality of compression springs 330 sleeved on the plurality of positioning rods 310. The two ends of the compression spring 330 respectively abut against the bottom end of the connecting rod 220 and the top end of the mounting plate 320. The pressing plate 240 is detachably mounted at the bottom end of the mounting plate 320. When the pressing plate 240 contacts the steel plate, the downward movement of the connecting rod 220 causes the positioning rod 310 to slide relative to the mounting seat. At this time, the downward movement of the connecting rod 220 compresses the compression spring 330, and the reaction force of the compression spring 330 causes the pressing plate 240 to press the steel plate tightly.

[0031] Based on the above solution, as Figure 5As shown, in the embodiment of the present utility model, a plurality of card slots 321 are spacedly opened at the lower end of the mounting plate 320, and a plurality of clamping blocks 241 are provided at the upper end of the pressing plate 240 corresponding to the plurality of card slots 321. The plurality of clamping blocks 241 can be clamped in the plurality of card slots 321, so as to facilitate the replacement of the pressing plate 240. By replacing the pressing plates 240 with different thicknesses, the distance between the bottom end of the pressing plate 240 and the bottom plate 230 in the vertical direction can be changed, thereby the magnitude of the pressing force of the pressing plate 240 on the steel plate can be adjusted, which is convenient to adjust the pressing force of the pressing plate 240 on the steel plate according to the actual situation and improves the practicability of the device.

[0032] Specifically, as Figure 5 shown, in the embodiment of the present utility model, an installation groove 221 is opened on one side wall of the connecting rod 220, and a plurality of positioning holes communicating with the installation groove 221 are opened at the bottom end of the connecting rod 220 corresponding to the plurality of positioning rods 310. The plurality of positioning rods 310 can slidably pass through the plurality of positioning holes, and limiting knobs 270 are provided at the ends of the plurality of positioning rods 310 located in the installation groove 221.

[0033] Based on the above scheme, as Figure 5 shown, in the embodiment of the present utility model, the bottom plate 230 is arranged on the L-shaped plate 210 through a tension spring 260, and at the same time, the steel plate can be tightly clamped during the clamping process by the acting force and the reaction force of the compressed tension spring 260.

[0034] Based on the above scheme, as Figures 4-5 shown, in the embodiment of the present utility model, two sets of the bottom plate 230, the pressing plate 240, the electric telescopic rod 250, the elastic telescopic member 300 and the tension spring 260 are provided in each set of the fixing assemblies 200 to clamp and fix the four sides of the steel plate to be cut, so as to further ensure the stable clamping and fixing of the steel plate.

[0035] Specifically, as Figure 5 shown, in the embodiment of the present utility model, limiting sliders are provided at both opposite ends of the connecting rod 220, and limiting chutes 211 are opened on the opposite inner sides of the two L-shaped plates 210 corresponding to the two limiting sliders. The limiting sliders are slidably arranged in the limiting chutes 211 to improve the stability of the connecting rod 220 during movement, thereby improving the stability of the pressing plate 240 pressing the steel plate and the cutting assembly 120 cutting the steel plate.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
