Description

Technical Field

[0001] This invention relates to the field of mechanical technology, specifically to a milling machine. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to mill workpieces. Milling machines are indispensable general-purpose equipment in the machinery manufacturing industry and are the second most produced machine tool after the lathe. With the development of science and technology and the socio-economic landscape, technological progress is influencing the economy and changing people's lifestyles. Currently, milling machines are used in the production process of every product, and a dedicated fixture is made for each production station on the milling machine. This fixture positions and holds the workpiece to facilitate the precision operation of the equipment for machining.

[0003] In industrial production, milling machines are frequently used to mill workpieces. The milling machine includes a base, a crossbeam, a mounting beam, and a milling cutter assembly. The crossbeam is mounted on the base, the mounting beam is slidably mounted on the crossbeam, and the milling cutter assembly is movably mounted on the mounting beam. When the milling machine is operating, the mounting beam can slide relative to the crossbeam, and the milling cutter assembly can move on the mounting beam, causing the milling cutter within it to rotate, thereby achieving the milling of the workpiece.

[0004] After milling is completed, existing technologies typically remove and store the milling cutter, only to reinstall it for the next machining operation. However, improper installation of the milling cutter is common, and frequent removal and installation make the milling process cumbersome. Therefore, a device for storing milling cutters is needed to avoid frequent disassembly. Furthermore, milling cutters wear down after a period of use. Existing technologies generally rely on visual inspection to determine the degree of wear, which is prone to errors. Additionally, abnormal noises from the cutting tool during milling require operator experience for assessment. Therefore, existing technologies lack a good method for quickly assessing milling cutter wear, impacting milling efficiency. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a milling machine capable of monitoring the wear level of the milling cutter via a camera, thereby controlling its condition. After use, the milling cutter can be lowered into a storage slot for safekeeping and protection, eliminating the need for repeated disassembly and reassembly and improving the milling machine's processing efficiency.

[0006] This invention is achieved through the following technical solution:

[0007] A milling machine includes a base, a cross slide, a worktable, a milling cutter, a spindle, a storage box, a motor, a spindle box, a pulley cover, and a column. The cross slide is fixed to the upper surface of the base, and the worktable is located above the cross slide. A column is vertically fixed above the base, and a spindle box is fixed to the outer side of the column. A spindle is located below the spindle box, and a milling cutter is fixed below the spindle. The side of the spindle box has a spindle lifting mechanism and a spindle box lifting mechanism, which are connected to the spindle drive. The storage box is located on the side of the column, directly below the milling cutter. A pulley is also fixed to the side of the column. The housing includes a pulley inside the pulley housing that is connected to the motor drive. The pulley housing is located above the spindle box. The storage box consists of two half-box units. A rotating shaft is fixed to the upper and lower surfaces of each half-box unit. The rotating shaft falls into the interior of a bearing seat. The bearing seat is fixed to the outer surface of the column. The storage box has a storage slot inside. A cooling plate is fixed to the side of the storage slot. The storage slot is fixed to the bottom of the storage box by a support base. A cover plate is provided on the upper surface of the storage box. A display screen is fixed to the side of the spindle box. A miniature camera is provided at the bottom of the storage slot. The display screen and the miniature camera are electrically connected.

[0008] A conduit is connected to the side of the cooling chip, and the conduit extends out to the outside of the half-box unit.

[0009] The cover plate consists of two cover plate units, which cover the upper surface of the half-box unit.

[0010] A sealing ring is fixed to the inner ring of the lower surface of the cover plate.

[0011] The sealing ring is a rubber sealing ring.

[0012] The main body of both the storage box and the pulley cover includes a metal outer layer, a polyurethane layer and a metal inner layer structure, with the polyurethane layer fixed between the metal outer layer and the metal inner layer.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention features a storage box on the side of the milling machine. After use, the milling cutter can be lowered into the storage slot, providing protection and eliminating the need for repeated disassembly and reassembly, thus improving the milling machine's processing efficiency. The storage box consists of two half-box units, which can be rotated to the side of the column when not in use, without affecting the milling operation. After the milling operation is completed, the two half-box units are magnetically joined together to store the milling cutter, making the storage box convenient to use. Furthermore, a miniature camera is installed at the bottom of the storage slot, displaying the image of the milling cutter head on the screen for easy observation of the cutter's wear and monitoring of its condition.

[0035] In this embodiment, the milling cutter 4 is fixed below the spindle 8. The milling cutter 4 can move up and down with the spindle lifting 5. The milling cutter 4 processes the workpiece on the surface of the worktable 3. After the milling cutter 4 finishes processing, the half-box unit 14 is rotated.
