When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When an element is referred to as being "disposed on" another element, it can be directly disposed on the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 4, in order to provide the shaft machining center runout correcting device of the present invention, the shaft machining center runout correcting device includes a body 10, a sleeve 20, a center 30, a block 40, a first fastening member 50, a sealing ring 60, a connecting member 70, a connecting plate 80, and a second fastening member 90.

The body 10 is cylindrical. The sleeve 20 is provided with a morse taper. The morse taper is located at the centroid of the sleeve 20. The sleeve 20 is provided with a number of first ramps 21. The first inclined surface 21 is located at the side of the sleeve 20. The first inclined surface 21 is inclined at an angle of 5 °. In the present embodiment, the number of the first inclined surfaces 21 is three.

The block 40 is provided with a second inclined surface 41, and the degree of inclination of the second inclined surface 41 is the same as that of the first inclined surface 21. In the present embodiment, the inclination angle of the second inclined surface 41 is 5 °. The block 40 is also provided with threaded holes.

The first fastener 50 and the second fastener 90 are socket head cap screws.

When the shaft type lathe machining center jumping correcting device is assembled, the center 30 is arranged in the Morse taper hole of the sleeve 20. The seal ring 60 is mounted on the sleeve 20, and the sleeve 20 is fixed to the body 10 by a hexagon socket flat set screw. The packing 60 is located between the sleeve 20 and the body 10 to prevent the cutting fluid from entering the spindle during wet machining. The first inclined surface 21 of the sleeve 20 forms a gap with the inside of the body 10. The block 40 is mounted in the gap. The first fastener 50 extends into a threaded hole in the block 40 to engage the body 10. At this time, the straight line of the three blocks 40 is triangular, and the straight line of the two adjacent blocks 40 forms an included angle of 60 degrees. The connection member 70 and the connection plate 80 are fixed to the body 10 by a second fastening member 90. The connection member 70 is located between the connection plate 80 and the body 10.

When the jumping of the tip 30 needs to be adjusted, the first fastening piece 50 is rotated, and the building block 40 axially moves to drive the sleeve 20 to radially move through loosening and locking of the first fastening piece 50, so that the jumping of the tip 30 is adjusted. The block 40 is locked by a screw with the deviation of 0.01mm in the depth direction, and the tip 30 moves 0.0009mm in the radial direction.

When it is desired to replace the tip 30, the first fastener 50 is loosened, the block 40 is forced axially outward, and the block 40 is removed. The tip 30 can be replaced by removing the sleeve 20 by loosening the socket cap set screw to force the sleeve 20 axially outward.

In the application, the building block 40 is axially locked and loosened by the first fastener 50 to bear force, so that the sleeve 20 generates radial movement to adjust the tip 30 to jump; the deviation of the building block 40 in the locking depth direction is 0.01mm through the first fastener 50, and the radial movement of the tip 30 is 0.0009mm, so that the jump of the tip 30 can be finely adjusted; when the second inclined surface 41 of the block 40 is locked with the first inclined surface 21 of the sleeve 20, a downward back tension is generated, so that the positioning surface of the sleeve 20 is tightly attached to the body 10.

The above examples only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, all according to the equivalent modifications and evolutions of the present invention, which are made to the above embodiments by the essential technology, and all belong to the protection scope of the present invention.
