[0042] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0043] Referring to Figures 1-5 , a center rest mechanism for a turning-milling compound machine tool, comprising: a sliding seat 15, a guide bar 18, a mounting seat 19, a center seat 20, a center clamping plate 22, and a sliding wheel 23.

[0044] A first guide rail 12 and a second guide rail 13 are respectively fixedly connected to the turning-milling compound machine tool 11, and the heights of the first guide rail 12 and the second guide rail 13 are different. A first slider 16 is slidably connected to the first guide rail 12, and a second slider 17 is slidably connected to the second guide rail 13; a guide rack 14 is located between the first guide rail 12 and the second guide rail 13, and there are height differences between the first guide rail 12, the second guide rail 13, and the guide rack 14. The extending directions of the first guide rail 12, the second guide rail 13, and the guide rack 14 are the same and are respectively horizontally arranged.

[0045] The sliding seat 15 is slidably mounted on the turning-milling compound machine tool 11. The guide bar 18 is fixedly connected to the sliding seat 15. The mounting seat 19 is fixedly connected to the sliding seat 15. A guide groove 24 is provided on the bottom wall of the mounting seat 19, and the guide bar 18 is slidably connected in the guide groove 24. The center seat 20 is fixedly connected to the side wall of the mounting seat 19. Two center clamping plates 22 are provided and are rotatably mounted on the center seat 20 symmetrically. The sliding wheel 23 is rotatably connected to one end of the center clamping plate 22.

[0046] In order to drive the sliding seat 15 to slide horizontally, a moving member is further provided. The moving member includes: a guide rack 14, a driving motor 25, and a gear 26. The guide rack 14 is fixedly connected to the turning-milling compound machine tool 11. The driving motor 25 is fixedly connected inside the bottom wall of the sliding seat 15. The gear 26 is fixedly connected to the output rotating shaft of the driving motor 25, and the gear 26 meshes with the guide rack 14.

[0047] A plurality of first waist-shaped holes 27 are equidistantly provided on the top wall of the sliding seat 15. A plurality of second waist-shaped holes 28 are equidistantly provided on the bottom wall of the mounting seat 19. Bolts are sequentially inserted into the second waist-shaped holes 28 and the first waist-shaped holes 27, and the sliding seat 15 and the mounting seat 19 are fixedly connected by the bolts.

[0048] The mounting base 19 is provided with two symmetrically positioned mounting holes 21. The central clamping plate 22 is an arc-shaped clamping plate, and one end of the central clamping plate 22 close to the central seat 20 is provided with a jack. Bolts are sequentially inserted into the jack and the mounting hole 21, and the central clamping plate 22 and the central seat 20 are connected by bolts and nuts.

[0049] Working or installation process:

[0050] According to the size of the workpiece, the position of the sliding seat 15 on the turning-milling compound machine tool 11 is determined, and the driving motor 25 is started. The output rotating shaft of the driving motor 25 drives the gear 26 to rotate. The gear 26 drives the sliding seat 15 to move by meshing with the guiding rack 14. The sliding seat 15 drives the first slider 16 and the second slider 17 to move, and through the guiding action of the first guide rail 12 and the second guide rail 13, the sliding seat 15 horizontally moves on the turning-milling compound machine tool 11 along the same extending direction of the first guide rail 12 and the second guide rail 13, and the sliding seat 15 is moved to the middle position of the workpiece. At this time, the driving motor 25 stops working and enters the self-locking mode, so that the sliding seat 15 is limited and stopped at this position on the turning-milling compound machine tool 11. And at this time, the two symmetrically positioned central clamping plates 22 up and down are respectively located on the upper and lower sides of the workpiece. By tightening the nuts on the bolts inserted into the jack and the mounting hole 21, due to the nuts being tightened on the bolts and the frictional force between the central clamping plate 22 and the central seat 20, the central clamping plate 22 is limited and fixed on the central seat 20, and the central clamping plate 22 cannot easily rotate around the axis of its own mounting hole 21. Thus, the central clamping plate 22 provides support for the middle section of the workpiece;

[0051] Since both the first waist-shaped hole 27 and the second waist-shaped hole 28 are waist-shaped holes, the mounting base 19 can be adjusted longitudinally, that is, the longitudinal distance between the two central clamping plates 22 and the workpiece can achieve the quick adjustment function of the steady rest.

[0052] The above description is only some preferred embodiments of the present disclosure and the description of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure that have similar functions.
