DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1 to Figure 2As shown, the utility model adopts the following technical scheme: a valve vertical turning, milling and boring composite high-efficiency machining CNC machine tool, including a workbench 1, and a hydraulic indexing chuck 4 arranged on the main shaft of the workbench 1, and a tool magazine bracket 2 arranged on the workbench 1, and a tool magazine 3 arranged on the tool magazine bracket 2, and a tool changing mechanism 13 arranged at the bottom of the tool magazine 3, and a column 5 arranged on the workbench 1, and a third slide rail 12 longitudinally arranged on the column 5, which is the Z axis of the machine tool, and a beam 6 arranged on the third slide rail 12 and can be lifted up and down, and a crossbeam 6 transversely arranged on the crossbeam The first slide rail 7 on 6 is the X-axis of the machine tool, and the slide plate 8 which can be moved laterally on the first slide rail 7, and the servo turret 11 which is arranged on the slide plate 8, and the second slide rail 9 which is arranged longitudinally on the slide plate 8 is the Y-axis of the machine tool, and the power boring and milling head 10 which can be lifted up and down on the second slide rail 9, a hydraulic locking device (not shown) is arranged at the bottom of the hydraulic indexing chuck 4, and the hydraulic indexing chuck 4 is connected to a indexing encoder, and the servo turret 11 is equipped with a boring tool, a turning tool, a milling tool, a grinding tool, a drilling tool and a tapping tool.

[0018] The hydraulic locking device includes a hydraulic cylinder, a clamping seat 16 that abuts against the hydraulic cylinder, a rack 14 arranged at one end of the clamping seat 16, an arc-shaped groove 17 arranged on the inner side of the clamping seat 16, and a gear 15 meshing with the rack 14. The rack 14 and the clamping seat 16 are two settings, and the two racks 14 are relatively arranged and mesh with the gear 15. The arc-shaped groove 17 matches the main shaft of the hydraulic indexing chuck 4, and the arc-shaped grooves 17 are respectively located on both sides of the main shaft.

[0019] The workbench 1 is provided with chip removal openings (not shown) which are inclined inward and downward around the hydraulic indexing chuck 4, and an automatic chip conveyor and a water tank (not shown) are provided below the chip removal openings.

[0020] The tool magazine 3, tool changing mechanism 13, hydraulic indexing chuck 4, power boring and milling head 10 and servo turret 11 are located on the same vertical plane.

[0021] The tool magazine 3 is a mechanical tool magazine equipped with 24 sixteen-type tools.

[0022] The power boring and milling head 10 is located between the tool magazine 3 and the servo turret 11 .

[0023] The workpiece is placed on the hydraulic indexing chuck 4 for fixing. According to the actual situation, the power boring and milling head 10 is moved to the side of the tool magazine 3.
