Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a rotating device for a horizontal machining center. Background Art

[0002] A three-jaw chuck consists of a chuck body, movable jaws and a jaw driving mechanism. Below the guiding parts of the three jaws on the three-jaw chuck, there are threads meshed with the flat thread on the back of the disc-shaped bevel gear. When a wrench is used to rotate the small bevel gear through a square hole, the disc-shaped gear rotates, and the flat thread on the back simultaneously drives the three jaws to move closer to or away from the center, so as to clamp workpieces with different diameters. An external motor is used as the power to drive the three-jaw chuck to rotate, realizing the rotation of the workpiece rod for machining.

[0003] Currently, when the jaws on the three-jaw chuck are used for clamping and positioning a cylinder, the contact area between the jaws and the cylinder is very small, resulting in unstable clamping of the cylindrical workpiece. Therefore, this application proposes a rotating device for a horizontal machining center. Summary of the Utility Model

[0019] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0020] As Figures 1 - 3 shown, an embodiment of the utility model provides a rotating device for a horizontal machining center, including:

[0021] A bracket 1, the bracket 1 penetrates through a first installation groove and a second installation groove, as Figure 1 shown;

[0022] Rotating assembly; the rotating assembly includes a support column 3 rotatably connected in the first installation groove and capable of adjusting the angle. Two short rods 2 are rotatably connected in the first installation groove, and both short rods 2 are fixedly connected to the support column 3. The inner wall of the second installation groove is provided with a drive box 7. A worm and worm gear are meshed in the drive box 7. The worm wheel is coaxially and fixedly connected to the short rod 2. A second motor 6 is installed on the drive box 7. The worm is fixedly connected to the output end of the second motor 6. When the second motor 6 works, it drives the worm and worm wheel to rotate, thereby realizing the rotation of the short rod 2. The rotation of the short rod 2 can drive the support column 3 and the three-jaw chuck 9 to rotate, and the angle of the three-jaw chuck 9 can be adjusted.

[0023] A shaft rod 8 is rotatably arranged through the support column 3. The bottom of the support column 3 is provided with a first motor 5. The bottom of the support column 3 is provided with a mounting plate 4, and the first motor 5 is installed at the bottom of the mounting plate 4; the output end of the first motor 5 is fixedly connected to the shaft rod 8, and a three-jaw chuck 9 is fixed to the upper end of the shaft rod 8. When the first motor 5 works, it drives the shaft rod 8 to rotate, thereby realizing the rotation of the three-jaw chuck 9. The three-jaw chuck 9 is a prior art; three adjustable jaws 10 are provided on the three-jaw chuck 9, and a T-shaped groove 11 is provided on the jaw 10, and the T-shaped groove 11 does not penetrate through the jaw 10.

[0024] A T-shaped block 12 which is limited is slidably connected in the T-shaped groove 11. An arc surface 13 is provided on the T-shaped block 12. Among them, a short shaft 15 is rotatably connected to the upper end of the jaw 10, a limit block 14 is fixed on the short shaft 15, and the limit block 14 abuts against the upper end of the T-shaped block 12. A torsion spring is installed between the short shaft 15 and the jaw 10. Through the torsion spring, the reset and positioning of the limit block 14 can be realized, making it not easy to shake.

[0025] When clamping a cylindrical workpiece, by controlling the three-jaw chuck 9, the three jaws 10 move relative to each other, and finally the jaws 10 clamp the cylindrical workpiece. At this time, the arc surface 13 on the T-shaped block 12 abuts against the cylindrical workpiece, so that the contact surface with the cylindrical workpiece can be increased, and the cylindrical workpiece can be stably clamped.

[0026] If cylindrical workpieces of different models are to be replaced, the corresponding T-shaped blocks 12 can be replaced. The operator manually rotates the limit block 14 so that it does not abut against and is not relative to the T-shaped block 12, and then removes the T-shaped block 12 and replaces it with a T-shaped block 12 of the same model, so that the arc surface 13 can closely adhere to the cylindrical workpiece, thereby being able to stably clamp the cylindrical workpiece.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
