Description

Technical Field

[0001] This utility model relates to a static pressure sector table, 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] Most machine tools use high-speed rotating grinding wheels or milling cutters to process workpieces. When the cutting tool in the machine 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 milling machine to process workpieces, it is necessary to realize the fan-shaped motion of the machine headstock and the linear motion in two vertical directions so that the workpiece can be processed by the cutting tool. In the existing technology, the friction is large when realizing the fan-shaped motion, and jamming is easy to occur. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned deficiencies in the existing technology and to provide a static pressure sector stage with a reasonable structural design.

[0006] Furthermore, the oil tank spacers are arranged in a ring-shaped structure.

[0007] Furthermore, the static pressure sector table also includes a sector table, and the oil tank pressure plate is disposed above the sector table and can perform sector-shaped movements on the sector table.

[0008] Furthermore, an oil drain hole is provided on the fan-shaped platform, and the oil drain hole is connected to the oil return groove.

[0009] Furthermore, the oil tank pressure plate is installed at the bottom of the headstock.

[0010] Furthermore, the oil tank pressure plate and the headstock are driven by a hydrostatic drive mechanism, which is mounted on the headstock.

[0011] Furthermore, the hydrostatic drive mechanism includes a hydrostatic drive motor, a hydrostatic drive synchronous pulley, a hydrostatic drive synchronous belt, and a hydrostatic guide wheel. The hydrostatic drive motor and the hydrostatic guide wheel are both mounted on the headstock. The hydrostatic drive synchronous pulley is mounted on the motor shaft of the hydrostatic drive motor.

[0025] 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.

[0026] Example

[0027] See Figures 1 to 5 As 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.

[0028] The hydrostatic sector platform in this embodiment includes a sector platform 1 and an oil tank pressure plate 2. The oil tank pressure plate 2 is located above the sector platform 1 and can make sector-shaped movements on the sector platform 1. The oil tank pressure plate 2 is installed at the bottom of the headstock 4. The oil tank pressure plate 2 and the headstock 4 are driven by a hydrostatic drive mechanism 3, which is installed on the headstock 4.

[0029] In this embodiment, an oil tank partition 21 is provided on the lower side of the oil tank pressure plate 2. The oil tank partition 21 is arranged in a ring structure. The inner side of the oil tank partition 21 is the oil filling tank 22, and the outer side of the oil tank partition 21 is the oil return groove 24. An oil filling hole 23 is provided on the oil tank pressure plate 2, which is connected to the oil filling tank 22. An oil drain hole 11 is provided on the fan-shaped platform 1, which is connected to the oil return groove 24.

[0030] The hydrostatic drive mechanism 3 in this embodiment includes a hydrostatic drive motor 31, a hydrostatic drive synchronous pulley 32, a hydrostatic drive synchronous belt 33, a hydrostatic guide wheel 34, a hydrostatic limit wheel 35, and a hydrostatic limit frame 36. The hydrostatic drive motor 31 and the hydrostatic guide wheel 34 are both mounted on the headstock 4. The hydrostatic drive synchronous pulley 32 is mounted on the motor shaft of the hydrostatic drive motor 31. The two ends of the hydrostatic drive synchronous belt 33 are respectively mounted on the two ends of the sector platform 1. The hydrostatic drive synchronous pulley 32 cooperates with the inner side of the hydrostatic drive synchronous belt 33, and the hydrostatic guide wheel 34 cooperates with the outer side of the hydrostatic drive synchronous belt 33. The hydrostatic limit frame 36 is mounted on the headstock 4, and the hydrostatic limit wheel 35 is mounted on the hydrostatic limit frame 36 and contacts the sector platform 1.

[0031] In this embodiment, there are two hydrostatic guide wheels 34, both of which are in contact with the outer side of the hydrostatic drive synchronous belt 33. There is one hydrostatic drive synchronous belt pulley 32, which meshes with the inner side of the hydrostatic drive synchronous belt 33. The two hydrostatic guide wheels 34 and the one hydrostatic drive synchronous belt pulley 32 are arranged in a triangular structure.

[0032] Specifically, the hydrostatic sector table can be used to realize the sector motion of the machine tool. When realizing the sector motion through the hydrostatic sector table, oil is injected into the oil injection hole 23 to fill the oil injection chamber 22 with oil, thereby generating a hydrostatic oil film between the upper surface of the sector table 1 and the lower surface of the oil chamber pressure plate 2. The hydrostatic drive motor 31 drives the hydrostatic drive synchronous pulley 32 to rotate. Since the hydrostatic drive synchronous pulley 32 meshes with the hydrostatic drive synchronous belt 33, the headstock 4 is mounted on the sector table 1 through the sector rotation center shaft 5, thereby allowing the headstock 4 and the oil chamber pressure plate 2 to perform sector motion along the sector rotation center shaft 5 on the sector table 1. During the sector motion, the hydrostatic limit wheel 35 can limit the headstock 4. When no oil is injected into the oil injection hole 23, the oil chamber partition 21 will contact the upper surface of the sector table 1, causing the oil to flow into the return oil groove 24 and be discharged through the drain hole 11.

[0033] 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.
