Description

Technical Field

[0001] This utility model relates to a machine head tilting device, belonging to the field of machine tools. Background Technology

[0002] Milling machines are machine tools that use milling cutters to process various surfaces of workpieces. The rotation of the milling cutter is usually the main motion, and the movement of the workpiece and the milling cutter is the feed motion. Grinding machines are machine tools that use grinding wheels to grind the surface of workpieces. Most grinding machines use high-speed rotating grinding wheels for grinding.

[0003] The cutting tool is mounted on the head assembly. When the cutting tool is a grinding wheel, the machine tool is a grinding machine; when the cutting tool is a milling cutter, the machine tool is a milling machine. When using a grinding machine or a milling machine to process a workpiece, the head assembly needs to be adjusted up and down by a head tilting device so that the workpiece can be processed by the cutting tool. In the existing technology, a lead screw structure is mostly used to control the up and down swing of the head assembly, and the lead screw structure cannot be positioned, resulting in poor stability of the head assembly.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] Example

[0021] See Figures 1 to 3As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0022] The head tilting device in this embodiment includes a tilting seat 1, a tilting drive mechanism 2, and a tilting positioning mechanism 3 for positioning the tilting drive slider 24. The tilting seat 1 is mounted on the head assembly 5, and the head assembly 5 is mounted on the head frame 4 via a self-aligning bearing 6. The tilting drive mechanism 2 cooperates with the tilting seat 1, and the tilting positioning mechanism 3 is mounted on the tilting seat 1 and is located below the tilting seat cavity 11.

[0023] In this embodiment, the swing angle seat 1 is provided with a swing angle seat cavity 11. The swing angle drive mechanism 2 includes a swing angle drive motor 21, a swing angle drive pulley 22, an eccentric shaft 23, and a swing angle drive slider 24. The swing angle drive slider 24 is mounted on the eccentric shaft 23 and is located inside the swing angle seat cavity 11. The swing angle drive pulley 22 is mounted on the eccentric shaft 23 and is driven by the swing angle drive motor 21 via a belt. The swing angle drive motor 21 and the eccentric shaft 23 are both mounted on the head frame 4.

[0024] The swing angle positioning mechanism 3 in this embodiment includes a swing angle positioning base plate 31, a swing angle positioning cylinder 32, and a swing angle positioning top plate 33. The swing angle positioning base plate 31 is installed on the swing angle seat 1 and is located below the swing angle seat cavity 11. The cylinder of the swing angle positioning cylinder 32 is installed on the swing angle positioning base plate 31. The piston rod of the swing angle positioning cylinder 32 is connected to the swing angle positioning top plate 33. The swing angle positioning top plate 33 cooperates with the swing angle driving slider 24.

[0025] Specifically, the head tilting device can be used in the machine tool to adjust the up and down tilting position of the head assembly 5. During adjustment, the tilting drive motor 21 drives the tilting drive pulley 22 to rotate, which in turn drives the eccentric shaft 23 to rotate. The eccentric shaft 23 drives the tilting drive slider 24 to make eccentric movements, while the tilting drive slider 24 slides in the tilting seat cavity 11. This, in turn, drives the head assembly 5 to tilt and adjust on the head frame 4 via the tilting seat 1. After adjustment, the tilting drive motor 21 stops rotating, and the tilting positioning cylinder 32 presses against the tilting positioning top plate 33, so that the tilting positioning top plate 33 abuts against the tilting drive slider 24 to achieve positioning of the tilting drive slider 24.

[0026] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model.
