[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model provides, for example Figs. 1-3 The multi-head machining center shown includes a machining center body 1, an operating table 2, a dust cover 3, a multi-head machining mechanism 4, a first machining axis 5, a second machining axis 6, a third machining axis 7, and a fourth machining axis 8. The operating table 2 is located inside the machining center body 1, and the operating table 2 is surrounded by dust covers 3. The multi-head machining mechanism 4 is located directly above the operating table 2. A cylinder is installed inside the multi-head machining mechanism 4, and the bottom of the multi-head machining mechanism 4 is connected to the first machining axis 5. The metal sleeve 601 on the second machining axis 6 is attracted by the magnetic seat 501. The magnetic seat 501 is equipped with a push rod 502, which is driven by a cylinder. The second machining axis 6 has an insertion hole 6021 and a mounting hole 603. The mounting hole 603 is for the insertion of the limit plug 604. The bottom of the limit plug 604 is connected to the third machining axis 7 by bolts 607. The bottom of the third machining axis 7 is equipped with two clamping parts 702, which are slidably connected to the fourth machining axis 8.

[0020] This invention enables the replacement of the first machining axis 5 on the multi-head machining mechanism 4 by being driven by a cylinder. The first machining axis 5 and the second machining axis 6 are also easy to disassemble and assemble. The second machining axis 6 and the third machining axis 7 are also easy to disassemble and assemble. The third machining axis 7 and the fourth machining axis 8 are also easy to disassemble and assemble, making it easy to adapt to the installation and use of more sizes and models of cutting heads.

[0021] The center of the third machining axis 7 has grooves on both sides, and springs 701 are installed in the grooves. Springs 701 are fixedly connected to clamping parts 702. Clamping parts 702 are adapted to the sliding grooves 801 on both sides of the fourth machining axis 8. The sliding grooves 801 are long strips with a deepened bottom. The height of the deepened part is adapted to the height of clamping parts 702. The bottom of the third machining axis 7 is open, and the diameter of its opening matches the diameter of the fourth machining axis 8. The bottoms of the second machining axis 6 and the first machining axis 5 are also open, but their opening diameters are different.

[0022] The No. 3 machining axis 7 and the No. 4 machining axis 8 are clamped and limited by the slide groove 801 and the clamping parts 702 on both sides. They can also be easily disassembled and assembled using the spring 701.

[0023] The limiting plug 604 is cylindrical with a circular plate at the bottom. A second insertion hole 6022 is provided on the side of the circular plate. A torsion spring rod 606 is provided at the center of the circular plate where it intersects with the first insertion hole 6021. The torsion spring rod 606 is connected between two limiting rods 605. Both ends of the limiting rods 605 extend out of the bottom circular plate of the limiting plug 604. The metal sleeve 601 is completely fitted on the magnetic seat 501. When the push rod 502 is driven by the cylinder, the metal sleeve 601 separates from the magnetic seat 501, and the limiting plug 604 is fixedly connected to the bolt 607. The bolt 607 is rotatably connected in the third machining shaft 7. The diameter of the second insertion hole 6022 is slightly larger than the diameter of the limiting rod 605.

[0024] The limit plug 604 is disassembled and assembled with the second machining axis 6 by inserting a thin needle into the first socket 6021 and the second socket 6022. The bolt 607 is rotated and installed and disassembled with the third machining axis 7, realizing two uses in one piece.

[0025] Working principle of this utility model:

[0026] Refer to the instruction manual appendix Figs. 1-3 When using this utility model, firstly, the entire multi-head machining mechanism 4 is equipped with multiple sets of machining shafts, which can be used to install various machining heads. If the fourth machining shaft 8 is replaced, the two clamping parts 702 need to be pushed outward to release the clamping parts 702 that were originally fixed in the deepening hole of the slide groove 801, and the fourth machining shaft 8 can be removed.

[0027] For example, if you want to replace the entire No. 2 machining axis 6, you need to drive the push rod 502 to separate the magnetic seat 501 and the metal sleeve 601 that were originally magnetically attached. Then you can replace the entire No. 2 machining axis 6 and install the tool head that is compatible with the inner hole of the No. 1 machining axis 5 onto the No. 1 machining axis 5.

[0028] Refer to the instruction manual appendix Figs. 3-6If the No. 3 machining axis 7 needs to be replaced, a fine needle needs to be inserted into the insertion hole 6021 to push the torsion spring rod 606 so that the two limit rods 605, which were originally in a straight line, are retracted into the limit plug 604, so that the originally fixed limit plug 604 is disengaged from the No. 2 machining axis 6. Then, the bolt 607 is used to separate the No. 3 machining axis 7 and replace it with a new No. 3 machining axis 7.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
