Technical Field

[0001] The invention relates to the technical field of milling equipment, in particular to a milling machine for mechanical processing. Background Art

[0002] A milling machine is a machine tool used for metal processing. It is mainly used to cut metal on the surface of the workpiece and form a specific shape. The milling machine removes the metal layer on the workpiece by rotating the tool, thereby processing the required plane, convex and concave surfaces, gears and other shapes. It is one of the common and important equipment in mechanical processing.

[0003] However, there are still some problems with machining milling machines. For example, in traditional milling machines, replacing the milling cutter usually requires manual operation, which involves a series of steps such as unclamping the chuck, disassembling the cutter, and re-clamping. This will significantly affect production efficiency and cost, especially when the cutter needs to be changed frequently or multi-step processing is required.

The insert block 27 is rotatably connected to the block 28. When the tool on the milling cutter disc 3 needs to be switched, the milling cutter disc 3 can be pushed toward the inner sleeve 5 so that the insert block 27 slides out of the tooth groove and enters the inside of the sleeve 5. The compression spring 29 is compressed. At this time, the milling cutter disc 3 connected to the block 28 through the insert block 27 can be rotated, and the tool to be used can be switched to the upper side of the center, corresponding to the upper spindle 4.

Block 30, before pushing the above-mentioned milling cutter disc 3 inward, it is necessary to unfold several limiting strips 23 to make the milling cutter disc 3 escape from the restriction of the limiting strips 23, rotate the swivel 6 on the sleeve 5, and the swivel 6 forms an extrusion on the front side ring frame 25 through the inclined surface blocks 30 on both sides and the corresponding inclined surface blocks 30 on the ring frame 25, and the ring frame 25 moves forward under the extrusion, and several tooth groove blocks fixed on the front side of the ring frame 25 also move forward with it. During the forward movement, the tooth groove blocks mesh with the corresponding spur gears 26 on the outside to transmit, so that the several limiting strips 23 connected to the sleeve 5 are unfolded and escape from the corresponding slots on the corresponding milling cutter disc 3, thereby realizing the pushing and rotation of the milling cutter disc 3; Furthermore, referring to Figure 4 , 5 , a plurality of sliders 8 corresponding to the milling head 24 are arranged in the milling cutter disc 3, and a plurality of slide grooves corresponding to the sliders 8 are opened in the milling cutter disc 3, a bearing seat 9 is rotatably connected to the slider 8, and the milling head 24 is installed in the corresponding bearing seat 9 through a bearing, a shaft sleeve 10 is fixed at the lower end of the spindle 4, and the milling head 24 is located inside the shaft sleeve 10, and a plurality of limiting blocks 11 corresponding to the milling head 24 are arranged on the edge of the milling cutter disc 3, and the limiting blocks 11 slide on the milling cutter disc 3, and the left and right sides of the front side of the slider 8 are fixed with support blocks 12, and the left and right sides of the lower side of the bearing seat 9 are opened with corresponding brackets 13. After the switching angle of the tool is changed, the limiting block 11 at the edge of the sliding edge causes the middle slide groove to leak out, and the bearing seat 9 transferred on the slider 8 can be flipped from the rear side of the milling cutter disc 3 to the front side of the milling cutter disc 3, and the limiting block 11 is moved back to its original position after flipping, and the brackets 13 on both sides of the bearing seat 9 fall on the corresponding support blocks 12 of the slider 8; Furthermore, referring to Figure 5-7A vertical block 18 is fixed on the upper side of the milling cutter disc 3, and a limit plate 19 that slides up and down is sleeved on the circumference of the vertical block 18. A slot corresponding to the vertical block 18 and the limit plate 19 is opened on the rear side of the sleeve 10. After the tool is replaced and turned over for use, the milling cutter disc 3 is reset and pulled back. At this time, the vertical block 18 and its upper limit plate 19 are slid into the inside of the sleeve 10 through the slot. A plurality of protrusions 17 are fixed on the circumference of the upper part of the milling head 24, and a plurality of grooves 21 corresponding to the protrusions 17 are opened on the lower side of the sleeve 10. A connecting block 22 located on the upper side of the limit plate 19 is fixed on the upper side of the vertical block 18.

Driven by the main shaft 4, the connected sleeve 10 rotates, and the sleeve 10 also drives the milling head 24 connected to the lower part to rotate, and the parts are processed; Furthermore, referring to Figure 4 , 6 , 7. A support bar frame 14 corresponding to the large rod of the telescopic rod 15 is fixed at the center of the lower side of the bearing seat 9. When the bearing seat 9 is flipped to the front side of the milling cutter disc 3, its support bar frame 14 falls on the corresponding large rod of the telescopic rod 15. Therefore, when the main shaft 4 of the milling machine body 1 is moved downward by the lifting device of the milling machine body 1, the force is applied to the multidirectional block 7 through the bearing seat 9 instead of the telescopic rod 15. A multidirectional block 7 is arranged at the center of the front side of the milling cutter disc 3. Telescopic rods 15 are arranged between the multidirectional block 7 and a plurality of sliders 8. A plurality of slide grooves corresponding to the multidirectional block 7 are provided on the front side of the milling cutter disc 3.

One end of the large rod of the telescopic rod 15 is rotatably connected to the multidirectional block 7, and one end of the small rod is rotatably connected to the corresponding slider 8, and a telescopic rod is sleeved around the small rod. The compression spring 16, when the spindle 4 drives the tool installed on the milling head 24 to move downward, the bearing seat 9 directly acts on the central multi-directional block 7 through the support bar frame 14, and the several telescopic rods 15 structure on the front side of the milling cutter disc 3, when the milling cutter moves downward, the telescopic rods 15 are retracted and the telescopic springs 16 are compressed, and the formed multilateral support structure also keeps the tool stable downward movement on the front side of the milling cutter disc 3, and at the same time provides support for the stable milling of the milling cutter. When the above-mentioned milling head 24 is assembled with the shaft sleeve 10 of the spindle 4, the entire milling head 24 is connected to the spindle 4 as a whole, and there is no gap between the milling head 24 and the bearing seat 9 for upward and downward movement, therefore, when the milling machine is lifted and adjusted for milling, the several telescopic rods 15 support structures on the front side of the milling cutter disc 3 can only serve as a simple stable support, and will not affect the shaking of the milling cutter.
