Description

Technical Field

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

[0002] A milling machine is a machine tool used for metal processing, mainly used for cutting metal on the surface of a workpiece and forming a specific shape. The milling machine removes the metal layer on the workpiece by rotating the cutting tool, thereby machining the required plane, concave-convex surface, gear and other shapes. It is one of the important and common equipment in machining.

[0003] However, there are still some problems with current 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 unlocking the chuck, disassembling the tool, and clamping again. Especially when frequent tool changes or multi-step machining processes are required, this will significantly affect production efficiency and cost;

[0004] The connection design between the milling head cutter and the spindle in traditional milling machines is not flexible enough. If the connection is not firm or adjusted improperly, it may lead to a decrease in cutting accuracy and even potential safety hazards;

[0014] Preferably, a plurality of limiting blocks corresponding to the milling heads are arranged at the edge of the milling cutter disc. The limiting blocks slide on the milling cutter disc. Support blocks are fixed to the left and right sides of the front side of the slider. Corresponding supporting grooves are formed at the left and right sides of the lower side of the bearing seat. A supporting strip frame corresponding to the large rod of the telescopic rod is fixed to the center of the lower side of the bearing seat, and a limiting ring corresponding to the supporting strip frame is fixed to the periphery of the large rod of the telescopic rod.

[0015] Preferably, a spur gear is fixed at the connection part of the limiting strip block, and a torsion spring is arranged at the connection part of the limiting strip block and the sleeve. A plurality of tooth groove blocks corresponding to the spur gear are arranged on the peripheral side of the surface of the sleeve, and the tooth groove blocks are fixedly connected to the rear side ring frame.

At the same time, several spring telescopic rod structures on the front side, when the milling cutter moves down, the springs on its circumference are compressed closer, and thus the support force provided for the milling cutter part is more sufficient, thereby ensuring highly precise milling of the machined parts.

[0021] In summary, at least three milling heads are pre-installed on the milling cutter head designed in the present invention. Each milling head can quickly and stably connect the milling cutter, and the stable support and precise adjustment of the milling cutter head are ensured through the limit adjustment and support structure at the rear side, making the tool easier to quickly replace and connect with the main shaft for efficient milling processing of parts.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0031] Referring to Figures 1-7 , a milling machine for machining includes a milling machine body 1. The milling machine body 1 includes a clamping seat 2. A main shaft 4 is arranged above the clamping seat 2. A sleeve 5 fixed to the milling machine body 1 is arranged above the rear side of the clamping seat 2. A milling cutter head 3 is arranged on the front side of the sleeve 5. At least three milling heads 24 are arranged on the milling cutter head 3. A milling cutter is installed at the lower part of the milling head 24. An insertion block 27 is fixedly arranged at the center of the rear side of the milling cutter head 3. A slot corresponding to the insertion block 27 is arranged inside the sleeve 5. An internally and externally sliding abutting block 28 is arranged inside the sleeve 5. A compression spring 29 is arranged between the inner side of the abutting block 28 and the sleeve 5. The insertion block 27 is rotatably connected to the abutting block 28. When it is necessary to switch the tool on the milling cutter head 3, the milling cutter head 3 can be pushed towards the sleeve 5, so that the insertion block 27 slides out of the tooth groove and enters the inside of the sleeve 5, and the compression spring 29 is compressed. At this time, the milling cutter head 3 connected to the abutting block 28 through the insertion block 27 can be rotated, and the used tool can be switched to the upper side of the center and corresponding to the upper main shaft 4;

[0032] Furthermore, referring to Figure 5 、 6, a ring frame 25 that slides back and forth is arranged outside the sleeve 5. A number of limiting strip blocks 23 are rotatably connected to the outer edge of the front end of the sleeve 5. A number of card slots corresponding to the limiting strip blocks 23 are provided on the back surface of the front milling cutter disc 3. A spur gear 26 is fixed at the connection point of the limiting strip blocks 23. A torsion spring is arranged at the connection point between the limiting strip blocks 23 and the sleeve 5. A number of tooth groove blocks corresponding to the spur gear 26 are arranged on the circumferential side of the surface of the sleeve 5, and the tooth groove blocks are fixedly connected to the rear ring frame 25. A rotating ring 6 is arranged at the rear side of the ring frame 25. The rotating ring 6 is rotatably connected to the outside of the sleeve 5. Bevel blocks 30 are fixedly arranged on the left and right sides of the front side of the rotating ring 6, and corresponding bevel blocks 30 are arranged on the left and right sides of the rear side of the ring frame 25. Before pushing the above-mentioned milling cutter disc 3 inward, it is necessary to unfold a number of limiting strip blocks 23 to release the milling cutter disc 3 from the restriction of the limiting strip blocks 23. Rotate the rotating ring 6 on the sleeve 5. The rotating ring 6 forms a squeeze on the front ring frame 25 through the bevel blocks 30 on both sides and the corresponding bevel blocks 30 on the ring frame 25. The ring frame 25 moves forward under the squeeze. A number of tooth groove blocks fixedly arranged on the front side of the ring frame 25 also move forward accordingly. During the forward movement of the tooth groove blocks, they mesh and drive with the corresponding spur gears 26 on the outside, so that a number of limiting strip blocks 23 connected to the sleeve 5 are unfolded and separated from the corresponding card slots on the corresponding milling cutter disc 3, and thus the pushing and rotation of the milling cutter disc 3 can be realized;

[0033] Furthermore, referring to Figure 4 , 5 , a number of sliders 8 corresponding to the milling heads 24 are arranged inside the milling cutter disc 3, and a number of sliding grooves corresponding to the sliders 8 are provided inside the milling cutter disc 3. A bearing seat 9 is rotatably connected to the slider 8. The milling head 24 is installed in the corresponding bearing seat 9 through a bearing. A bushing 10 is fixed at the lower end of the main shaft 4. The milling head 24 is located inside the bushing 10. A number of limiting blocks 11 corresponding to the milling heads 24 are arranged at the edge of the milling cutter disc 3. The limiting blocks 11 slide on the milling cutter disc 3. Supporting blocks 12 are fixedly arranged on the left and right sides of the front side of the slider 8, and corresponding supporting grooves 13 are provided on the left and right sides of the lower side of the bearing seat 9. After adjusting the switching angle of the cutting tool in use, slide the limiting blocks 11 at the edge to expose the middle sliding groove. The bearing seat 9 connected to 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. After flipping, move the limiting blocks 11 back to their original positions, and the supporting grooves 13 on both sides of the bearing seat 9 fall on the corresponding supporting blocks 12 of the slider 8;

[0034] Furthermore, referring to Figures 5-7, a vertical block 18 is fixed on the upper side of the milling cutter disc 3. A limiting disc 19 that slides up and down is sleeved on the circumferential side of the vertical block 18. A slot corresponding to the vertical block 18 and the limiting disc 19 is opened at the rear side of the sleeve 10. After the cutting tool is adjusted and flipped for use, the milling cutter disc 3 is reset and pulled back. At this time, the vertical block 18 and the limiting disc 19 thereon slide into the inside of the sleeve 10 through the slot. A number of bumps 17 are fixed on the circumferential side of the upper part of the milling head 24. A number of grooves 21 corresponding to the bumps 17 are opened at the lower side inside the sleeve 10. A connecting block 22 located above the limiting disc 19 is fixed on the upper side of the vertical block 18. A stud 20 corresponding to the connecting block 22 is fixed inside the sleeve 10, and a through hole corresponding to the stud 20 is opened in the connecting block 22. Release the bearing seat 9, and the milling head 24 and the vertical block 18 thereon both slide up. The vertical block 18 slides into the inside of the sleeve 10, and the connecting block 22 thereon passes through the stud 20. At this time, the stud 20 is screwed with the corresponding nut to make it close to the lower side surface of the connecting block 22. At the same time, the bumps 17 on the circumferential side of the milling head 24 are all clamped into the corresponding grooves 21 on the inner side of the lower part of the sleeve 10. Driven by the main shaft 4, the connected sleeve 10 rotates, and the sleeve 10 drives the lower-connected milling head 24 to rotate for part processing;

[0035] 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 moves down under the action of the lifting device of the milling machine body 1, the acting force acts on the multi-directional block 7 through the bearing seat 9, rather than on the telescopic rod 15. A multi-directional block 7 is arranged at the center of the front side of the milling cutter disc 3. Telescopic rods 15 are arranged between the multi-directional block 7 and a number of sliders 8. A number of chutes corresponding to the multi-directional block 7 are opened at the front side of the milling cutter disc 3. The telescopic rod 15 is composed of two thin rods with different diameters and the same length. The small rod slides inside and outside the large rod. One end of the large rod of the telescopic rod 15 is rotatably connected to the multi-directional block 7, one end of the small rod is rotatably connected to the corresponding slider 8, and a telescopic spring 16 is sleeved on the circumferential side of the small rod. When the cutting tool installed on the milling head 24 is driven by the main shaft 4 to move down, the bearing seat 9 directly acts on the central multi-directional block 7 through the support bar frame 14. For the structure of a number of telescopic rods 15 on the front side of the milling cutter disc 3, when the milling cutter moves down, the telescopic rod 15 expands and contracts, and the telescopic spring 16 is compressed. The formed multi-sided support structure also keeps the tool moving down stably 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. Since when the milling head 24 is assembled with the sleeve 10 of the main shaft 4, the entire milling head 24 and the main shaft 4 are integrated, and there is no up-and-down moving gap between the milling head 24 and the bearing seat 9, therefore, when the milling machine is lifted and adjusted for milling, the support structure of a number of telescopic rods 15 on the front side of the milling cutter disc 3 can only act as a simple and stable support, and will not affect the shaking of the milling cutter.

[0036] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
