DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0023] Combined with Figure 1 , a vertical machining center structure for workpiece positioning, comprising a base 1, a support plate 3 fixedly connected to the upper end of the base 1, a fixing plate B6 fixedly connected to one side of the support plate 3, a moving component 7 for moving the machining position and a cooling component 5 for cooling the machining fixedly connected to the lower end of the fixing plate B6, a switching component 4 for switching cutting tools fixedly connected to the lower end of the moving component 7, and a waste chip groove 12 opened at the upper end of the base 1.

[0024] The present utility model will be further described below in conjunction with embodiments.

[0025] Embodiment 1:

[0026] Please refer to Figure 1 , a fixing rod A2 and a fixing rod B8 are fixedly connected to the upper end of the base 1, a rotating motor A21 is fixedly connected to one side of the fixing rod A2, a cylinder 81 is fixedly connected to one side of the fixing rod B8, a rotating motor B82 is fixedly connected to the telescopic end of the cylinder 81, and a clamping component 9 for clamping the workpiece is fixedly connected to the output ends of the rotating motor A21 and the rotating motor B82. The clamping component 9 includes telescopic rods B91 respectively fixedly connected to the output ends of the rotating motor A21 and the rotating motor B82, electromagnetic plates 93 fixedly connected to both ends of the telescopic rods B91, a polyurethane pad 92 fixedly connected to one side of the telescopic rods B91, and a magnetic attraction force exists between the two groups of electromagnetic plates 93.

[0027] Specifically, the telescopic rod B91 expands and contracts to adjust the distance between the two groups of electromagnetic plates 93 to ensure that the workpiece can be placed. Subsequently, the workpiece is placed in the middle of the electromagnetic plates 93, so that one end of the workpiece contacts one of the polyurethane pads 92. Subsequently, the cylinder 81 extends, so that the rotating motor B82 approaches the rotating motor A21, so that the other polyurethane pad 92 contacts the workpiece, and the magnetic attraction force between the electromagnetic plates 93 can attract each other, so that the workpiece can be attracted by the attraction force without contact, reducing the wear suffered by the workpiece clamping. The rotating motor A21 and the rotating motor B82 can rotate to adjust the angle of the workpiece, and the fixed connection of the telescopic rod B91 can adjust the positions of the two groups of electromagnetic plates 93. When the distance between the two groups of electromagnetic plates 93 is far due to the large size of the workpiece and the attraction force becomes poor, the polyurethane has a high friction coefficient and can increase the friction force, making the clamping of the workpiece more stable.

[0028] Embodiment 2:

[0029] Please refer to Figures 1 - 4, the moving component 7 includes a slide rail 71 fixedly connected to the lower end of the fixed plate 6. The inner wall of the slide rail 71 is fixedly connected with a telescopic cylinder 73. A slider 72 is slidably connected inside the slide rail 71. The telescopic end of the telescopic cylinder 73 is fixedly connected with the slider 72. The cooling component 5 includes a cooling box 51 fixedly connected to the lower end of the fixed plate 6. A pump body 52 is fixedly connected to the inner wall of the cooling box 51. The water outlet end of the pump body 52 is fixedly connected with a hose 53. A positioning plate 2 and a limiting plate 8 are fixedly connected to the upper end of the base 1. A rubber pad A21 is fixedly connected to one side of the positioning plate 2. A screw rod 81 is threadedly connected to one side of the limiting plate 8. A clamping plate 82 is rotatably connected to one side of the screw rod 81. A rubber pad 83 is fixedly connected to one side of the clamping plate 82. A connecting plate 84 is fixedly connected to one side of the clamping plate 82. A mounting plate 85 is fixedly connected to one side of the connecting plate 84. A telescopic rod C86 is fixedly connected to one side of the mounting plate 85. A brush 87 is fixedly connected to one side of the telescopic rod C86. A filter screen 11 is fixedly connected to the upper surface of the base 1. The inside of the base 1 is a cavity.

[0030] Specifically, according to the cutting tool required for processing adjustment, the motor 42 runs to drive the rotating shaft 45 to rotate. When the required cutting tool is at the lowest position, the motor 42 stops running, realizing the replacement of cutting tools of different sizes and specifications. The telescopic rod A41 can extend to drive the cutting tool to descend for cutting. When the blade is worn after long-term use and needs to be replaced, rotate the arc blocks A44, B411, and C49 corresponding to the tool handle A43, tool handle B412, and tool handle C410, so that the arc blocks A44, B411, and C49 move positions. At this time, the corresponding tool handles A43, B412, and C410 can be pushed downward to replace the new blade. The pump body 52 pumps the coolant in the cooling box 51 into the hose 53 and pours it at the connection between the workpiece and the blade during the processing to cool down, reducing the adverse effects caused by excessive temperature on the workpiece. After the processing is completed, the telescopic rod C31 extends to make the moving rod 32 move, driving the brush 33 to move, which can contact the upper surface of the base 1 for cleaning, and the waste chips fall into the waste chip groove 12 for recycling.
