[0035] Please refer to Figure 1 ,in Figure 1 It is a structural schematic diagram of the processing machine tool of the present utility model.

[0036] In the figures, structurally similar elements are denoted by the same reference numerals.

[0037] This embodiment provides a highly stable machining platform that can be used on a machining machine. The machining machine includes a machining platform 15, a crossbeam frame 11, a movable module 12, a lifting module 13, and a cutter head 14. The movable module 12 is slidably mounted on the crossbeam frame 11, the lifting module 13 is slidably mounted on the movable module 12, and the cutter head 14 is mounted on the lifting module 13. This allows the cutter head 14 to be driven to move laterally and to be lifted vertically to machine different locations on a workpiece 27. A drive mechanism such as a lead screw mechanism or a linear motor can be used to drive the movement of the movable module 12 and the lifting module 13.

[0038] The processing machine tool in this embodiment includes two processing platforms 15, each of which is equipped with a set of moving modules 12, lifting modules 13, and a cutting head 14. The two processing platforms 15 can rotate the workpiece 26 to opposite sides so that the two cutting heads 14 do not interfere with each other.

[0039] Please refer to Figure 2 The processing platform 15 includes: a working platform 25, a clamping mechanism 27, and an initial setting mechanism 28. One side of the working platform 25 is a working surface for mounting a workpiece 26.

[0040] Please refer to Figure 2 and Figure 6 , multiple clamping mechanisms 27 are respectively arranged on the four sides of the working platform 25. The clamping mechanism 27 includes a cylinder 271, a clamping block 273, and a support block 272. The cylinder 271 is fixedly connected to the working platform 25, the support block 273 is fixedly connected to the cylinder body of the cylinder 271, the clamping block 273 is rotatably connected to the support block 272, one end of the clamping block 272 is connected to the telescopic rod of the cylinder 271, and the other end of the clamping block 273 is used to clamp the workpiece 26.

The preliminary setting mechanism 28 includes a positioning member and a spring 284. The positioning member includes a connecting block 281 and a positioning block 282. The connecting block 281 and the positioning block 282 are connected to form an L-shaped structure. The connecting block 281 is embedded and rotatably arranged on the working platform 25.

[0042] The positioning member includes an initial position and a working position on the rotation trajectory. When the positioning member is at the initial position, such as Figure 3 The middle positioning member is located at the initial position, the positioning block 282 is retracted into the working platform 25 or protrudes from the working surface at a first height, and the end of the connecting block 281 away from the positioning block 282 protrudes from the working surface.

[0043] When the positioning part is in the working position, Figure 4The middle positioning member is located in the working position, the positioning block 282 protrudes from the working surface by a second height, which is greater than the first height, and the positioning block 282 is in positioning contact with the side of the workpiece 26, and the end of the connecting block 281 away from the positioning block 282 is flush with the working surface.

[0044] In this way, when the workpiece 26 is placed on the work platform 25, the workpiece 26 will press down the end of the connecting block 281 away from the positioning block 282, so that the positioning block 282 contacts the side of the workpiece 26 to form a positioning, which is convenient and efficient to operate and can reduce the processing and manufacturing cost of the workpiece.

[0045] The spring 284 is provided between the connecting block 281 and the working platform 25 . The spring 284 is located at one end of the connecting block 281 away from the positioning block 282 . The spring 284 is used to drive the positioning member to remain in the initial position.

[0046] Please refer to Figure 5 Optionally, one side of the positioning block 282 is provided with a protruding block 286 for positioning contact with the side of the workpiece 26. The protruding block 286 can better position contact with the side of the workpiece 26 to avoid interference between the edges of the workpiece 26 and the positioning piece, affecting normal positioning.

[0047] Please refer to Figure 3 Optionally, a groove 283 is provided at the inner intersection of the connecting block 281 and the positioning block 282 to prevent the edge of the workpiece 26 from interfering with the inner intersection of the connecting block 281 and the positioning block 282 and affecting normal positioning.

[0048] Specifically, the work platform 25 is provided with a mounting slot for mounting the preliminary positioning mechanism 28. The preliminary positioning mechanism 28 also includes a mounting block 285. A connecting block 281 is rotatably mounted on the mounting block 285. A spring 284 is disposed between the connecting block 281 and the mounting block 285. The mounting slot is provided with an elongated hole. The mounting block 285 is provided with a mounting hole. A screw passes through the elongated hole and the mounting hole and is connected to a nut to lock the mounting block 285 in the mounting slot. The connection position of the mounting block 285 on the work platform 25 can be adjusted by moving along the elongated hole, thereby enabling multiple preliminary positioning mechanisms 28 to position workpieces 26 of different sizes.

[0049] In this embodiment, an initial setting mechanism 28 is provided between the two clamping mechanisms 27 on each side of the working platform 25 .

[0050] Please refer to Figure 2 In this embodiment, the highly stable processing platform 15 further includes a moving platform 21 , a supporting base 22 , a first rotating platform 23 , and a second rotating platform 24 .

[0051] The support base 22 is fixedly set on the mobile platform 21. The support base 22 has a U-shaped structure. The first rotating platform 23 is rotatably connected to the inner side of the support base 22. The second rotating platform 24 is rotatably connected to the first rotating platform 23. The rotation axis of the first rotating platform 23 is perpendicular to the rotation axis of the second rotating platform 24. The working platform 25 is set on one side of the second rotating platform 24.

[0052] By moving the mobile platform 21 and rotating the first rotating platform 23 and the second rotating platform 24, the workpiece 26 on the working platform 25 can be moved and rotated, which facilitates multi-faceted processing of the workpiece 26, reduces assembly times and assembly errors, and improves work efficiency.

[0053] Among them, a plurality of first T-slots 211 are arranged in parallel on the top surface of the mobile platform 21, and a first connecting hole is arranged on the support seat 22. The screws pass through the first T-slots 211 and the first connecting holes and are threadedly connected with the nuts, thereby fixing the mobile platform 21 and the support seat 22, and the position of the support seat 22 can be adjusted more conveniently.

[0054] In addition, a plurality of second T-slots are provided parallel to one side of the second rotating platform 24, and a second connecting hole is provided on the work platform 25. The mating structure of the second T-slots and the second connecting hole is similar to that of the first T-slots 211 and the first connecting hole 225. The structure of the second T-slots and the second connecting hole is not illustrated in this embodiment. Screws pass through the second T-slots and the second connecting hole and threadably engage with nuts, thereby securing the work platform 25 to the second rotating platform 24. Different work platforms 25 can be disassembled and replaced to clamp and secure different workpieces 26.

[0055] In this embodiment, a first driving mechanism 29 for driving the first rotating platform 23 to rotate is provided on one side of the support seat 22. A mounting cavity is provided in the first rotating platform 23, and a second driving mechanism for driving the second rotating platform 24 to rotate is provided in the mounting cavity.

[0056] The highly stable machining platform of this preferred embodiment utilizes a rotating positioning member to first control the work platform 25 to rotate so that the work surface faces upward. Then, when a workpiece 26 is placed on the work platform 25, the workpiece 26 presses down on the end of the connecting block 281 away from the positioning block 282, causing the positioning block 282 to contact the side of the workpiece 26 to achieve positioning. This facilitates efficient operation and reduces workpiece machining costs. After the workpiece 26 is placed and positioned, the cylinder 271 controls the clamping block 273 to clamp the workpiece 26.

[0057] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
