[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0023] The column spindle box turning tool frame of the machining center comprises a bed 1, a workbench 2 is fixedly installed on the top of one side of the bed 1, a slide 3 is movably installed on the side of the bed 1 away from the workbench 2, and the slide 3 is arranged side by side with the workbench 2; a turning frame 4, the turning frame 4 is arranged on the top of one side of the slide 3, a column body 5 is arranged in the middle of the turning frame 4, a spindle box body 6 is arranged on one side of the column body 5, a turning mechanism is arranged between the column body 5 and the turning frame 4, and the turning mechanism includes a lifting hole- 7. Hook 8 and sling 9. A hoisting hole 7 is provided at the middle of the top of the column body 5. A sling 9 is provided between the hoisting hole 7 and the spindle box body 6. The middle of the sling 9 is movably connected to the hook 8. The turning mechanism also includes a hoisting hole 2 10. The hoisting hole 2 10 is provided at the middle of the bottom end of the column body 5. The hoisting hole 2 10 and the hoisting hole 1 7 are on the same vertical line. A guide surface 11 is provided on the bottom lower end surface of the column body 5. A lifting bar 12 is movably installed between the two sides of the top of the turning frame 4.

[0024] In this embodiment, when installing the column body 5, the machining center can lift the column body 5 through the turning frame 4 and place it on the slide 3, so that the fit between the guide surface 11 at the bottom end of the column body 5 and the slide 3 can be confirmed. If the fit is up to standard, the turning frame 4 is removed and the column body 5 is installed on the slide 3. If the fit is not up to standard, the turning frame 4 is controlled to turn 180° in conjunction with the lifting device, so that the guide surface 11 on the lower end face of the column body 5 faces upward, which is convenient for moving to the scraping and grinding station for processing, thereby achieving the purpose of easy turning.

[0025] Working principle: When this machining center detects the accuracy between the guide surface 11 of the lower end surface of the column body 5 and the slide 3, it can detect the installation geometric accuracy of the column body 5 and the spindle box body 6 on the bed 1, and then press Figure 2 and Figure 3 As shown, the column body 5 and the spindle box body 6 are lifted, and the lifting hole 17 is connected to the spindle box body 6 by the lifting belt 9, and the hook 8 is connected to the lifting device after being sleeved on the lifting belt 9. At this time, the column body 5 is lifted by the lifting device, and then the turning frame 4 is placed on the upper end of the slide 3, and then the lifting device is controlled to lower the column body 5 until the guide surface 11 at the bottom end of the column body 5 is docked with the slide 3. If there is an accuracy problem after docking, the column body 5 is controlled to rise again, and then the lifting bar 12 is passed through the lifting hole 2 10 at the bottom end of the column body 5, and then the column body 5 is controlled to descend until the two ends of the lifting hole 2 10 are placed on both sides of the top of the turning frame 4, and then it continues to descend. At this time, the column body 5 is flipped due to its own gravity, so that the guide surface 11 at the bottom faces upward, and then the column body 5 is moved to the scraping station to scrape the guide surface 11 according to the detection data.
