For example, a CNC drilling, tapping and milling machining center disclosed in Chinese Patent Publication No. CN219189301U directly fixes the machining center on the workpiece through a fixing mechanism, and then controls the movement of the machining device through three feeding mechanisms, and processes the workpiece through the machining device. However, the position of the fixing mechanism cannot be changed, and this type of machining center is fixed to the workpiece only by the cooperation of bolts and nuts, which results in a relatively small scope of application of this type of machining center.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0026] The positioning bracket 9 includes a U-shaped plate 91. The left and right sides of the first rectangular cylinder 5 are in contact with the inner wall of the U-shaped plate 91. The left and right sides of the inner wall of the U-shaped plate 91 are fixedly connected with a cylinder 92. The cylinder 92 is located in the strip hole 12. The length and height of the strip hole 12 are greater than the diameter of the cylinder 92. The cylinder 92 can move up and down or forward and backward in the strip hole 12. The bottom of the cylinder 92 is in contact with the upper surface of the first rubber pad 7. A first circular hole 93 is opened at the bottom of the U-shaped plate 91. The inner wall of the first circular hole 93 is fixedly connected with a first threaded cylinder 94. The inner wall of the first threaded cylinder 94 is threadedly connected with a pressing bolt 95. The surface of the pressing bolt 95 is fixedly connected with a bearing 96 A pressing block 97 is fixedly connected to the surface of the bearing 96, and the upper surface of the pressing block 97 contacts the bottom of the second rubber pad 8. The pressing block 97 is connected to the pressing bolt 95 through the bearing 96, and the pressing block 97 can rotate freely on the pressing bolt 95. When the cylinder 92 is in close contact with the first rubber pad 7 and the pressing block 97 is in close contact with the second rubber pad 8, the position of the U-shaped plate 91 cannot be changed through the friction between the cylinder 92 and the first rubber pad 7 and the friction between the pressing block 97 and the second rubber pad 8. When the cylinder 92 is separated from the first rubber pad 7 and the pressing block 97 is separated from the second rubber pad 8, the U-shaped plate 91 can move back and forth on the rectangular cylinder. Example

[0027] Reference Figure 1-8The front and rear sides of the fixing plate 10 are both fitted with a second rectangular tube 13, the bottom of the second rectangular tube 13 is fixedly connected with an electromagnet 14, the outer surface of the second rectangular tube 13 is provided with a second circular hole 15, the inner wall of the second circular hole 15 is fixedly connected with a second threaded tube 16, the inner wall of the second threaded tube 16 is threadedly connected with a limiting bolt 17, the surface of the limiting bolt 17 contacts the inner wall of the fixing hole 11, the surface of the limiting bolt 17 is fixedly connected with a limiting ring 18, the bottom of the limiting ring 18 contacts the upper surface of the fixing plate 10, and the bottom of the inner wall of the second rectangular tube 13 is bonded with a third rubber pad 1 9. The upper surface of the third rubber pad 19 contacts the bottom of the fixed plate 10. The maximum distance between the limiting bolt 17 and the third rubber pad 19 is greater than the thickness of the fixed plate 10. When the limiting ring 18 and the third rubber pad 19 clamp the fixed plate 10, the electromagnet 14 can be fixed on the fixed plate 10 through the friction between the third rubber pad 19 and the fixed plate 10, and the machining center can be directly fixed on the workpiece through the suction force of the electromagnet 14 on the workpiece. When the limiting ring 18 and the third rubber pad 19 loosen the fixed plate 10, the second rectangular cylinder 13 can be directly removed from the fixed plate 10.

When multiple second rectangular tubes 13 are placed together, the multiple second rectangular tubes 13 can be fixed together through the suction force between adjacent magnetic blocks 20, making it more convenient to carry or store the multiple second rectangular tubes 13.

[0029] In the utility model, when the user uses the machining center, he first adjusts the position of the fixing plate 10 according to the position of the mounting hole on the workpiece. When adjusting, he first rotates the pressing bolt 95 to separate the pressing block 97 from the second rubber pad 8 and the cylinder 92 from the first rubber pad 7. At this time, the U-shaped plate 91 can move freely back and forth on the rectangular cylinder. Then, the U-shaped plate 91 is moved to a suitable position, and the pressing bolt 95 is rotated to make the pressing block 97 contact with the second rubber pad 8 and the cylinder 92 contact with the first rubber pad 7. At this time, the friction between the cylinder 92 and the first rubber pad 7 and the friction between the pressing block 97 and the second rubber pad 8 can make the position of the U-shaped plate 91 unable to change. Then, the fixing bolt is used to fix the U-shaped plate 91. and the nut, the machining center is fixed on the workpiece. When there is no preset mounting hole on the workpiece, the second rectangular tube 13 is first sleeved on the fixed plate 10, and the limiting bolt 17 is rotated to clamp the limiting ring 18 and the third rubber pad 19 on the fixed plate 10, and the electromagnet 14 can be fixed on the fixed plate 10 through the friction between the third rubber pad 19 and the fixed plate 10. At the same time, when the electromagnet 14 is turned on, the suction force of the electromagnet 14 on the workpiece can directly fix the machining center on the workpiece. After the machining center is fixed on the workpiece, the processing device 4 can be moved in multiple directions through the cooperation of the first horizontal feeding mechanism 1, the second horizontal feeding mechanism 2 and the vertical feeding mechanism 3, and the workpiece is processed by the processing device 4.
