DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] The present application provides a milling structure of a vertical machining center, as shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , which comprises a machine tool body 1, a milling frame 2 fixedly installed on the machine tool body 1, a first support plate 3 fixedly installed on the milling frame 2, a telescopic transmission rod 4 fixedly installed on the first support plate 3, and a fixing mechanism arranged at the bottom of the telescopic transmission rod 4 for milling.

[0027] The fixing mechanism comprises a threaded column 5 fixedly installed on the telescopic transmission rod 4, a plurality of springs 6 arranged inside the threaded column 5, an elastic clamping block 7 slidingly installed inside the threaded column 5, a nut 8 screwed on the threaded column 5, and a milling cutter 9 slidingly installed inside the threaded column 5, one end of the spring 6 being fixedly installed inside the threaded column 5, and the other end of the spring 6 being fixedly installed on the elastic clamping block 7.

[0028] In use, place the machine tool body 1 in a suitable location. First, manually squeeze the elastic clamping block 7 inwards until its head is inserted into the nut 8. The limiting ring inside the nut 8 limits the elastic clamping block 7. Then, rotate the nut 8 a short distance around the threaded post 5. Next, insert the milling cutter 9 into the nut 8. Continue rotating the nut 8, which will move the elastic clamping block 7 into the threaded post 5. The movement of the elastic clamping block 7 compresses the spring 6, and the head of the elastic clamping block 7 retracts inwards, thus clamping the milling cutter 9. Finally, start the external motor to drive the telescopic transmission rod 4, which is connected to the first support plate 3, to rotate. The rotation of the telescopic transmission rod 4 drives the threaded column 5 and the milling cutter 9 inside the threaded column 5 to rotate, thereby performing a milling operation on the material. The milling cutter 9 of the vertical machining center needs to be replaced after a period of use, re-ground and reinstalled. During disassembly, by rotating the nut 8 in the opposite direction, the nut 8 will move outward while rotating. Through the elastic potential energy of the spring 6, the spring 6 will push the elastic clamping block 7 outward. Since the elastic clamping block 7 itself is elastic, the head of the elastic clamping block 7 opens outward when it moves outward. At this time, the milling cutter 9 can be pulled out and replaced. Then, the new milling cutter 9 is put back into the threaded column 5 and clamped by the above operation.

[0029] Furthermore, in order to clamp the material during milling, such as Figure 1 , Figure 3 and Figure 4 As shown, a transverse moving column 10 is fixedly installed on the milling frame 2, a longitudinal moving column 11 is slidably installed on the transverse moving column 10, a base plate 12 is fixedly connected to the longitudinal moving column 11, and a sliding groove 13 is provided on the top of the base plate 12.

[0030] A fixing plate 14 is fixedly connected to the base plate 12, a fixing block 15 is fixedly connected to the base plate 12, a movable plate 16 is slidably connected inside the slide groove 13, and a threaded rod 17 is screwed into the inside of the fixing block 15.

[0031] The fixed block 15 has a threaded hole inside that matches the threaded rod 17. One end of the threaded rod 17 is rotatably connected to one side of the movable plate 16, and the end of the threaded rod 17 away from the movable plate 16 is fixedly connected to a handwheel 18.

[0032] In use, the material is placed on the bottom plate 12, and one side of the material is aligned with the fixed plate 14, then the hand wheel 18 is manually rotated, the threaded rod 17 is rotated in the fixed block 15 by the rotation of the hand wheel 18, so as to drive the moving plate 16 to move along the sliding groove 13, then the material is clamped by the moving plate 16 and the fixed plate 14, during milling, the longitudinal moving column 11 can move transversely along the transverse moving column 10, and the bottom plate 12 with the material on the bottom plate 12 can move longitudinally along the longitudinal moving column 11, so that each position of the material can be milled during milling of the material by changing the position of the material.

[0033] It should be noted that, in order to make the milling cutter 9 move up and down, as shown in Figure 1 、 Figure 4 and Figure 5 , the milling frame 2 is slidably connected with a transverse lifting column 19, the bottom of the transverse lifting column 19 is fixedly connected with a second support plate 21, the first support plate 3 and the second support plate 21 are fixedly connected with an extension rod 20, and the extension transmission rod 4 penetrates through the second support plate 21.

[0034] The spring 6 is arranged in an annular array in the threaded column 5, and the nut 8 is provided with a limiting ring for limiting the elastic clamping block 7.

[0035] In use, the transverse lifting column 19 can move up and down, the second support plate 21 and the milling cutter 9 can move up and down by the up-and-down movement of the transverse lifting column 19 and the up-and-down movement of the extension rod 20, and the material is milled when the milling cutter 9 moves up and down.

[0036] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
