[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a hydraulic cross indexing automatic slot milling machine of the utility model comprises a bottom plate 15 and a plurality of shells 1, wherein the shells 1 are arranged above the bottom plate 15, the top surface and the opposite surface of the shells 1 are both openly arranged, the interior of the shells 1 are all covered with limit assemblies for positioning the workpiece, a pressing plate 4 for pressing the workpiece is arranged above the shells 1, a cylinder 5 for driving the pressing plate 4 to move up and down is installed above the pressing plate 4, a fixing frame 6 is installed between the cylinder 5 and the shell 1, a shaft 11 is installed on the outside of the fixing frame 6, an inner ring 9 and an outer ring 10 for driving the shell 1 to rotate are arranged outside the shaft 11, and a fixing seat 13 connected to the bottom plate 15 is installed at the bottom of the outer ring 10;

[0021] Among them, the base plate can be replaced with a positive and negative thread linear slide. The movable platform on the positive and negative thread linear slide can be connected to the fixed seat. The movable platform can drive the movement of the fixed seat and the shell by moving inward or outward, thereby changing the distance between the shells, so that workpieces of different lengths can be fixed, increasing adaptability.

[0022] In this embodiment, the outer ring 10 is sleeved on one end of the inner ring 9, and the end of the inner ring 9 not covered by the outer ring 10 is annularly structured and equipped with multiple convex teeth 14. A brake motor 8 is installed on the outside of the outer ring 10, and gears 7 are installed on the rotating shaft of the brake motor 8. The gears 7 are meshed and connected with the convex teeth 14, and multiple connecting rods 12 are installed between the inner ring 9 and the shaft 11.

[0023] In this embodiment, the limiting components include a positioning rod 2, a positioning cylinder 3 and a compression spring. One end of the positioning rod 2 is inserted into the positioning cylinder 3, and the other end is installed on the inner wall surface of the shell 1. The compression spring is arranged inside the positioning cylinder 3. One end of the compression spring is installed on the inner wall surface of the positioning cylinder 3, and the other end is installed on the positioning rod 2.

[0024] In this embodiment, a positioning ring is installed on the outer ring surface of the inner ring 9, and a positioning groove of an annular structure is provided on the inner ring surface of the outer ring 10 opposite to the positioning ring. The positioning ring is movably arranged in the positioning groove so that the inner ring can only rotate along the positioning groove, thereby preventing the inner ring from detaching from the outer ring.

[0025] In this embodiment, a gap is formed between the pressing plate 4 and the housing 1 for placing the workpiece, so that the workpiece can be placed on the top of the housing along the gap.

[0026] In this embodiment, the housing 1 and the limiting assembly are both made of metal materials, which increases the firmness and load-bearing performance of the housing and the limiting assembly and can better fix the workpiece.

[0027] When in use, both ends of the workpiece can be placed in the shell. After being placed in, the cylinder can be started to extend the piston rod of the cylinder. The extension of the piston rod drives the pressure plate, and the workpiece can be squeezed by the downwardly moving pressure plate. As the workpiece moves downward, the positioning cylinder covered by the workpiece will move downward along the positioning rod until the positioning cylinder and the positioning rod are pressed together, thereby avoiding the situation where the positioning rod and the positioning cylinder move again. The positioning cylinder that is not in contact with the workpiece can be wrapped outside the workpiece. The two ends of the workpiece can be fully wrapped by the positioning cylinder and the pressure plate, thereby completing the positioning of the workpiece, so that the cutting equipment on the slot milling machine can perform slot milling operations on the workpiece.

[0028] Among them, after the milling groove on one side is completed, the brake motor can be started. The start of the brake motor drives the gear. The rotation of the gear drives the convex tooth and the inner ring. The rotation of the inner ring drives the connecting rod and the shaft. The rotation of the shaft drives the shell and the pressure plate. The rotating shell can automatically complete the flipping operation of the workpiece, and can make all surfaces of the workpiece quickly face the cutting equipment of the milling machine.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
