Description

Technical Field

[0001] The utility model relates to the technical field of milling machines, in particular to a milling machine that can be quickly maintained. Background Art

[0002] Milling machines are specialized machines widely used in manufacturing and engineering. Their primary function is to remove material from a metal workpiece through a cutting operation, thereby producing the desired shape, size, and even surface texture. Milling machines operate based on the synergy between a rotating tool and a moving table, enabling them to perform a wide variety of complex machining tasks.

[0003] It can process planes, curved surfaces, holes and grooves, and can also complete high-precision processing of complex parts. The application scope of milling machines includes mold manufacturing, parts production, gear processing and many other fields.

[0004] However, in actual production and use, milling machines also have certain defects. For example, the lifting system of the tool in the milling machine mostly uses a screw for lifting, and the thread will bear the gravity of the slide during the lifting process. Even if lubrication measures are taken, the thread will wear out during long-term use, resulting in a decrease in the lifting accuracy of the slide, affecting production quality. To replace the screw, the slide and part of the lifting structure need to be removed before the screw can be replaced. The slide itself is heavy, and it requires a lot of manpower to dismantle it, which is very inconvenient. The milling machine itself will generate a large amount of metal debris during the milling process, and will use a large amount of coolant. The mixture of debris and coolant will flow down from the workbench and enter the drive structure under the workbench, interfering with the drive structure. Utility Model Content

[0026] See Figure 1-Figure 3As shown, the detachable screw lifting structure includes a lifting motor 6 which is vertically arranged at the lower position of the support frame 1 through bolts, the driving shaft of the lifting motor 6 is connected to the lifting screw 7, the top of the lifting screw 7 is connected to the bearing 8 which is arranged in the support frame 1 through bolts, and a screw slider 9 is installed on the lifting screw 7 through a thread, and one end of the screw slider 9 is connected to the slide 3 through a bolt; two lifting rails 10 are vertically provided on the front side of the support frame 1, and a lifting slider 11 is provided on each lifting rail 10, and the lifting slider 11 is connected to the slide 3 through bolts.

[0027] As an optimization solution of the present invention, the lifting screw 7 is driven to rotate by the lifting motor 6, and the screw slider 9 is driven to rise and fall by the thread, thereby driving the slide 3 to rise and fall. At the same time, the bearing 8 can bear part of the weight to prevent the lifting motor 6 from causing excessive pressure. The bolts can be easily disassembled, and when disassembling, the screw can be removed by removing the bearing 8, the connection between the lifting motor 6 and the lifting screw 7, and the bearing 8 can be selectively removed for easy operation.

[0028] See Figure 1-Figure 3 As shown, the quick fixing structure includes a load-bearing rod 12 arranged on one side of the lifting slider 11, a hanging rod 13 is provided on the slide 3 at one side of the load-bearing rod 12, and a plurality of positioning rods 15 are vertically arranged on the support frame 1 at the other side of the load-bearing rod 12. A steel wire rope 14 is provided on the load-bearing rod 12, and both ends of the steel wire rope 14 are respectively provided with "O"-shaped connecting rings. The connecting ring at one end of the steel wire rope 14 is movably mounted on the load-bearing rod 12, and the connecting ring at the other end of the steel wire rope 14 is movably mounted on the hanging rod 13; the top positions of the load-bearing rod 12, the hanging rod 13 and the positioning rod 15 are all provided with protruding anti-slip blocks.

[0029] As an optimization solution of the present invention, by setting the load-bearing rod 12 and the wire rope 14, one end of the wire rope 14 can be directly removed from the hanging rod 13 and connected to the positioning rod 15 when needed, so that the wire rope 14 can fix the distance between the positioning rod 15 and the load-bearing rod 12, thereby limiting the height of the slide 3 to prevent the slide 3 from falling, and the anti-slip block can prevent the wire rope 14 from slipping.

[0030] See Figure 1-Figure 5 As shown, the waste collection structure includes a collector 2 17 arranged at the long sides of both sides of the workbench 5, and a collector 16 is respectively provided at the short sides of both sides of the workbench 5. Collector 1 16 and collector 2 17 are both provided with collection grooves, and matching magnetic blocks 18 are embedded in collector 1 16, collector 2 17 and the side of the workbench 5.

[0031] As an optimization solution of the present invention, the installation of collector 16, collector 2 17 and workbench 5 is facilitated by the magnetic block 18. During use, the mixture of coolant and debris generated can be collected by the collection trough to prevent it from falling directly into the structure below and affecting the operation of the equipment.

[0032] The use process of this utility model:

[0033] First, install the equipment and use it, and install the collector 16 and the collector 2 17 on the workbench 5 through the magnetic block 18. During use, the collector 16 and the collector 2 17 can collect the coolant and debris, and the user can remove them and dump them regularly;

[0034] After long-term use, the lifting accuracy decreases. When the lifting screw 7 needs to be replaced, the slide 3 is first adjusted to a suitable height so that the slide 3 will not block the bearing 8 and the lifting motor 6 below. The ends of the wire ropes 14 on both sides connected to the hanging rod 13 are removed and put on the appropriate positioning rod 15. Then, the lifting motor 6 drives the slide 3 to slowly descend, so that the wire rope 14 is tightened, and the connection between the bearing 8 and the lifting motor 6 and the lifting screw 7 can be removed by bolts. At this time, the wire rope 14 will bear the weight of the slide 3, and the lifting rail 10 and the lifting slider 11 will keep the slide 3 from tilting. The lifting screw 7 is manually adjusted. The rod 7 rotates and turns upward out of the screw slider 9 and the bearing 8, and the old lifting screw 7 can be removed; when removing the bearing 8 and the connection between the lifting motor 6 and the lifting screw 7, you can choose to remove the bearing 8, and then rotate and remove the lifting screw 7 by simply turning it out of the screw slider 9 to take it out, reducing the operation time; then install the new lifting screw 7 and put the accessories back. After completion, start the lifting motor 6 again, lift the slide 3 slightly upward, so that the wire rope 14 is loosened, that is, remove the end of the wire rope 14 hanging on the positioning rod 15, and put it back on the hanging rod 13, and then fine-tune the equipment, and the milling machine can be put into use again.
