[0004] The present invention relates to a Y-axis mounting bracket for a machine tool, comprising a mounting bracket body and a mounting platform fixed to the bottom of the mounting bracket body; the mounting bracket body is provided with horizontally arranged mounting groove I and mounting groove II; mounting groove I is located in the middle of the mounting bracket body and is used to install an X-axis ball screw mechanism; there are two mounting grooves II, which are respectively located on both sides of mounting groove I and are used to fix and install X-axis guide rails.

[0005] Furthermore, the mounting groove I and mounting groove II are integrally formed on the front of the fixing frame body, and several rectangular back weight reduction grooves are distributed on the back of the fixing frame body.

[0006] Furthermore, a connecting plane is formed at the bottom of the fixing frame body; a number of connecting holes are distributed on the connecting plane for connecting with the top surface of the mounting platform.

[0007] Furthermore, the connecting plane has several rectangular bottom weight-reduction grooves distributed on it.

[0008] Furthermore, a triangular support frame is provided between the back of the fixing frame body and the mounting platform.

[0009] Furthermore, several reinforcing ribs are integrally formed between the back of the fixing frame body and the outer wall of the back weight reduction groove.

[0010] Furthermore, an X-axis lead screw bearing seat and an X-axis motor bracket are respectively provided at both ends of the mounting groove I; a Y-axis lead screw bearing seat and a Y-axis motor bracket are provided in the middle of the bottom surface of the mounting platform.

[0011] Furthermore, the bottom of the installed platform is equipped with two rows of Y-axis sliders.

[0012] The beneficial effects of this utility model are as follows: The Y-axis mounting bracket for machine tools of this utility model has two integrally formed main bodies: mounting groove I and mounting groove II. Mounting groove I is used to mount the lead screw, motor, etc. of the X-axis ball screw mechanism, while mounting groove II is used to mount the X-axis guide rail.

Detailed Implementation

[0022] like Figure 1 As shown, the Y-axis mounting bracket for machine tools in this embodiment includes a mounting bracket body and a mounting platform 16 fixed to the bottom of the mounting bracket body.

[0023] like Figure 1 As shown, the mounting bracket body is vertically fixed on the mounting platform 16. The front of the mounting bracket body is provided with horizontally arranged mounting grooves I3 and II4. A connecting plane 7 is formed at the bottom of the mounting bracket body. Multiple connecting holes 1 are provided on the connecting plane 7. The mounting platform 16 is fixedly connected through the connecting plane 7. The connection is achieved by fasteners such as bolts engaging with the connecting holes 1.

[0024] The mounting groove I3 is horizontally located at the center of the front of the fixed frame body and is used to install the X-axis ball screw mechanism. At both ends of the mounting groove I3, X-axis screw bearing seats 14 are installed through bearing seat mounting holes 2, and X-axis motor brackets are installed through motor bracket mounting holes 6, thereby installing the X-axis screw drive motor 12. There are two mounting grooves II4, located on both sides of the mounting groove I3. Multiple guide rail mounting holes 5 are distributed within the mounting grooves II4 for fixing and installing X-axis guide rails 13. Figure 7 As shown, the X-axis module A of the machine tool is provided with an X-axis slider that cooperates with the X-axis guide rail 13, thereby realizing the sliding connection between the X-axis module A and the Y-axis module B; the X-axis module A is also provided with an X-axis nut for cooperating with the X-axis ball screw 15, and the X-axis ball screw mechanism drives the entire X-axis module A to translate in the horizontal direction to realize the feed motion in the X-axis direction.

[0025] like Figure 4As shown, in this embodiment, the mounting groove I3 and mounting groove II4 are integrally formed on the front of the fixing frame body. Six rectangular back weight-reducing grooves 9 are distributed on the back of the fixing frame body, and six bottom weight-reducing grooves 8 corresponding to the back weight-reducing grooves 9 are also distributed on the connecting plane 7 at the bottom of the fixing frame body, thereby greatly reducing the overall weight of the fixing frame. Six reinforcing ribs 10 are also distributed on the back of the fixing frame body. The reinforcing ribs 10 are integrally formed between the outer wall of the back weight-reducing grooves 9 and the back of the fixing frame body, corresponding to the spaces between two adjacent back weight-reducing grooves 9. Since the back weight-reducing grooves 9 weaken the overall strength of the fixing frame to a certain extent, reinforcing ribs are provided for reinforcement.

[0026] like Figure 5 and 6 As shown, the mounting platform 16 in this embodiment is horizontally positioned and is fixedly connected to the connecting plane 7 at the bottom of the mounting frame body. The bottom of the mounting platform 16 is equipped with a Y-axis slider 17, a Y-axis lead screw bearing, and a Y-axis lead screw motor, thereby mounting the Y-axis lead screw 18. The X-axis ball screw mechanism and the Y-axis ball screw mechanism are perpendicular to each other. Rotation of the Y-axis ball screw mechanism can drive the entire Y-axis mounting frame to translate relative to the bed C along the Y-axis direction, achieving the Y-axis feed motion. Figure 7 The machine bed should be equipped with a Y-axis guide rail that mates with the Y-axis slider 17, and a Y-axis nut that mates with the Y-axis lead screw. For example... Figure 5 A triangular support frame 11 is provided between the back of the fixed frame body and the mounting platform 16 to improve the connection strength and stability between the mounting platform 16 and the fixed frame body.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model are included within the protection scope of the present utility model.
