Description

Technical Field

[0001] The present invention relates to the field of mica plate processing equipment, in particular to a milling machine and a production process for mica plate machine tool processing. Background Art

[0002] Mica sheets are industrial materials made primarily from mica. Mica is a rock-forming mineral with finely flaked crystals. Its chemical composition primarily consists of aluminum silicates of potassium, aluminum, magnesium, iron, and lithium. Depending on the production process and application requirements, mica sheets can be categorized as natural or synthetic. Natural mica sheets are made by bonding mica paper with organic silicone water and then pressing it under heat, preserving the natural properties of mica. Synthetic mica sheets, on the other hand, are manufactured from artificially synthesized mica raw materials through a specific process, resulting in superior purity and performance consistency. Due to mica's excellent insulation properties, high-temperature resistance, chemical stability, and mechanical strength, mica sheets are widely used in numerous fields, including electronics, aerospace, new energy, and metallurgy. In the field of electronics and electrical appliances, mica boards are often used to manufacture insulating components, electric heater frames, etc. to ensure the safe and stable operation of equipment; in the aerospace field, its high temperature resistance and high insulation properties make it an ideal choice for manufacturing aircraft engine insulation components and electrical system insulation materials; in the field of new energy, mica boards can be used for the insulation and protection of solar photovoltaic equipment and wind power generation equipment, improving equipment reliability. However, in the processing of mica boards, milling machines are one of the commonly used processing equipment. When using milling machines to perform cutting, milling and other processing operations on mica boards, a large amount of fine dust will inevitably be generated. This dust will not only cause serious pollution to the working environment of the processing workshop and affect the health of the operators, but long-term inhalation of mica dust may lead to respiratory diseases such as pneumoconiosis; moreover, this dust can easily enter the precision components of the milling machine, accelerating component wear, reducing the service life of the equipment and processing accuracy; in addition, dust may also adhere to the surface of the processed mica board, affecting product quality, causing product defects, increasing scrap rate, and increasing production costs. Therefore, there is an urgent need for a technology or device that can effectively reduce or treat the dust generated when milling machines are used to process mica boards, so as to improve the processing environment, protect the health of operators, and enhance equipment performance and product quality.

DETAILED DESCRIPTION

[0019] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explaining the present invention and are not intended to limit the present invention.

[0020] Example 1, as Figure 1 As shown, this embodiment provides a milling machine for machining mica boards, which includes a milling machine body 100, a tool mounting seat 110 provided on the milling machine body 100, and a moving mechanism provided on the milling machine body 100. The moving mechanism is used to drive the tool mounting seat 110 to move along the X-axis, Y-axis, or Z-axis on the milling machine body 100. In this embodiment, the length direction of the milling machine body 100 is the X-axis direction, the width direction of the milling machine body 100 is the Y-axis direction, and the height direction of the milling machine body 100 is the Z-axis direction. The moving mechanism realizes the X-axis, Y-axis, and Z-axis movement of the tool mounting seat 110 through a ball screw drive structure. Since the moving mechanism has the same structure as the three-axis drive device of a common milling machine, it will not be described in detail in this embodiment.

[0021] Combine Figure 2 as well as Figure 3 As shown, the tool mounting seat 110 is provided with a spindle motor 210, combined with Figure 7 as well as Figure 8 As shown, in this embodiment, in order to realize the installation of the spindle motor 210, the tool mounting seat 110 includes a base 710 and a connecting seat 720 bolted to the base 710, a base groove 810 is provided at the base 710, and a connecting seat groove 820 is provided at the connecting seat 720, and the base groove 810 and the connecting seat groove 820 together constitute a motor mounting groove 730 for installing the spindle motor 210.

[0022] The shaft of the spindle motor 210 is connected to a cutting head 310; the end face of the tool mounting seat 110 near the cutting head 310 is recessed inward to form an annular groove 320 arranged along the circumference of the spindle motor 210, and an annular plate 330 is provided in the annular groove 320 and is sleeved on the outer periphery of the cutting head 310. The annular plate 330 can slide along the axial direction of the shaft of the spindle motor 210; the lower end of the annular plate 330 is flush with the distal end of the cutting head 310, and a circular annular panel 220 is provided at the tool mounting seat 110 and at the open end of the annular groove 320. The lower end of the annular panel 220 is provided with a rubber sealing cover 230, which is fixed to the outer wall of the annular panel 220 by a clamp. Figure 9 As shown, a connecting ear 910 is provided at the edge of the enclosure 220 , and the connecting ear 910 is bolted to the tool mounting seat 110 .

[0023] The outer wall of the enclosure 220, the rubber sealing cover 230, and the annular plate 330 and the inner wall of the annular groove 320 constitute an air intake chamber 340, and the tool mounting seat 110 is provided with an air intake mechanism for supplying air into the air intake chamber 340; an exhaust chamber 350 is formed between the inner side wall of the annular plate 330 and the inner wall of the annular groove 320, and the tool mounting seat 110 is provided with an exhaust mechanism for extracting air from the exhaust chamber 350; an annular plate opening 360 is provided at the lower end portion of the annular plate 330; and a control mechanism for starting the air intake mechanism and the exhaust mechanism when the cutting head 310 is working is provided in the tool mounting seat 110.

[0024] During use, when the cutting head 310 at the tool mounting seat 110 is cutting the mica board, the control mechanism is started, and the air pump draws air from the outside through the air inlet pipe 240, and passes through the air inlet port 420 and the air inlet channel 410 in sequence into the air inlet chamber 340 (composed of the enclosure 220, the rubber sealing cover 230, and the outer wall of the annular plate 330); the air flow in the air inlet chamber 340 is ejected from the annular plate opening 360 and blown toward the processing area of ​​the cutting head 310, so that the dust in the exhaust chamber 350 (between the inner wall of the annular plate 330 and the inner wall of the annular groove 320) is blown up, and the industrial vacuum cleaner extracts the dust-containing air in the exhaust chamber 350 through the exhaust pipe 250, the exhaust port 440 and the exhaust channel 430, and discharges it after dust removal and filtration, forming a negative pressure airflow to ensure that the dust is effectively adsorbed.

[0025] The milling machine used for mica board machining in this embodiment can promptly remove the dust concentration generated during mica board machining, preventing the dust generated during mica board machining from escaping and causing a poor workshop environment. This prevents the health hazards of mica powder inhaled by workers in the production workshop, and better protects the workers in the mica board production workshop. It also prevents dust from entering components such as the spindle motor 210 and the ball screw, thereby better protecting the milling machine body 100 and better extending the service life of the milling machine body 100. By removing the dust generated during mica board machining in real time, the cleanliness of the mica board surface is ensured, and dust is prevented from adhering to the surface of the mica board and affecting product quality, resulting in product defects.

[0026] The silicone rubber sealing cover 230 forms a dynamic seal with the surface of the mica board to prevent dust from escaping.

[0027] Combine Figure 4As shown, the air intake mechanism includes an air intake channel 410 disposed in the tool mounting base 110 and communicating with the air intake chamber 340. The tool mounting base 110 is provided with an air intake port 420 located at the opening of the air intake channel 410. The air intake port 420 is provided with an air intake pipe 240, and the air intake pipe 240 is connected to an air pump. The exhaust mechanism includes an exhaust channel 430 disposed in the tool mounting base 110 and communicating with the exhaust chamber 350. The tool mounting base 110 is provided with an exhaust port 440 located at the opening of the exhaust channel 430. The exhaust port 440 is provided with an exhaust pipe 250, and the exhaust pipe 250 is connected to an industrial vacuum cleaner.

[0028] During use, when the air pump is started, the external air flow path is: air pump → air inlet pipe 240 → air inlet 420 → air inlet channel 410 (internal channel of tool mounting seat 110) → air inlet cavity 340 → annular plate opening 360 → exhaust cavity 350; thereby blowing away the dust in the mica board processing area.

[0029] When the industrial vacuum cleaner is started, the flow path of the dust in the exhaust chamber 350 is: exhaust chamber 350 → exhaust channel 430 → exhaust port 440 → exhaust pipe 250 → industrial vacuum cleaner; thereby the dust in the exhaust chamber 350 is extracted.

[0030] Furthermore, the bottom end surface of the annular groove 320 is recessed inward to form an annular plate mounting cavity 370, a control cavity 450 is provided at the tool mounting seat 110, and a control cavity opening 460 communicating with the annular plate mounting cavity 370 is provided at the control cavity 450, an insulating block 470 is provided at the top end of the annular plate 330, and the end of the insulating block 470 extends into the control cavity 450 through the control cavity opening 460, and an annular plate mounting cavity 370 is provided with an annular plate spring 380 for pushing the lower end of the annular plate 330 to be flush with the end of the cutting head 310.

[0031] During use, when the cutting head 310 is pressed down, the annular plate 330 overcomes the elastic force of the annular leaf spring 380 and slides upward. After the cutting is completed, it automatically resets under the action of the annular leaf spring 380, so that when cutting the mica board, it can cooperate with the board surface of the mica board and the structural parts of the tool mounting seat 110, and form an air intake cavity 340 and an exhaust cavity 350 at both ends of the annular plate 330 respectively, so that the dust in the exhaust cavity 350 can be sucked out by cooperating with an air pump and an industrial vacuum cleaner.

[0032] Combine Figure 5As shown, the control mechanism includes a conductive block 510 arranged at the insulating block 470, a first conductive column 520 is provided at the conductive block 510, and the first conductive column 520 is connected to the first cable 260. The control cavity 450 is also provided with a conductive plate mounting seat 530 arranged along its height, an L-shaped conductive plate 540 is provided at the conductive plate mounting seat 530, a second conductive column 550 is provided at the L-shaped conductive plate 540, and the second conductive column 550 is connected to the second cable 270; when the cutting head 310 is working, the annular plate 330 moves toward the end of the annular plate spring 380 to make the conductive block 510 contact with the L-shaped conductive plate 540. When the conductive block 510 contacts the L-shaped conductive plate 540, the first cable 260, the second cable 270, the air pump, the industrial vacuum cleaner and the external power supply form a closed loop.

[0033] When the cutting head 310 at the tool mount 110 is inserted into the mica board to cut it, the annular plate 330 presses against the mica board surface, causing it to move upward. The insulating block 470 then drives the conductive block 510 upward to contact the L-shaped conductive sheet 540. The closed circuit path is: external power supply → first cable 260 → first conductive post 520 → conductive block 510 → L-shaped conductive sheet 540 → second conductive post 550 → second cable 270 → air pump / industrial vacuum cleaner → power neutral. This allows the air pump and industrial vacuum cleaner to operate, removing dust generated by the cutting head.

[0034] With this arrangement, when the cutting head 310 is pressed down to contact the mica plate, the annular plate 330 slides, triggering the conductive block 510 to contact the L-shaped conductive sheet 540. This synchronizes the activation of the air pump and industrial vacuum cleaner, ensuring that dust is promptly removed as it is generated. Compared to traditional equipment that requires an operator to manually activate the dust removal system, the present invention automatically controls the start and stop of the air pump and industrial vacuum cleaner through mechanical linkage, preventing dust exposure caused by operator inadvertent errors.

[0035] Combine Figure 6 As shown, a plurality of spring mounting cavities 610 are provided at the conductive sheet mounting seat 530. The plurality of spring mounting cavities 610 are spaced apart along the height direction of the conductive sheet mounting seat 530 and open toward the end of the L-shaped conductive sheet 540. A conductive sheet spring 620 is provided in the spring mounting cavity 610 for pressing the L-shaped conductive sheet 540 against the conductive block 510.

[0036] By setting the conductive sheet spring 620, the L-shaped conductive sheet 540 can be in better contact with the conductive block 510, avoiding failures caused by poor contact between the L-shaped conductive sheet 540 and the conductive block 510, thereby better improving the stability of the milling machine used for mica board machine processing during use.

[0037] Example 2: This example provides a mica board production process based on the milling machine for mica board machining in Example 1, which includes the following steps: Step 1: Place the mica plate to be processed on the milling machine body 100; Step 2: Move the tool mounting base 110 so that the cutting head 310 moves to the processing area of ​​the mica board, and then start the spindle motor 210 to process the mica board through the cutting head 310; when the cutting head 310 descends to process the mica board, the annular plate 330 is squeezed and moves toward the end of the annular plate spring 380, and the conductive block 510 contacts the L-shaped conductive sheet 540. The first cable 260, the second cable 270, the air pump, the industrial vacuum cleaner and the external power supply form a closed loop. The air pump sends external air into the air inlet chamber 340 and enters the exhaust chamber 350 through the annular plate opening 360, thereby blowing up the dust in the exhaust chamber 350. The industrial vacuum cleaner extracts the dust-containing air in the exhaust chamber 350 through the exhaust channel 430, thereby cleaning the dust. Step 3: After the mica plate is processed, remove the mica plate from the milling machine body 100 .

[0038] Through the above process, the dust generated during the mica board production process can be removed in time, thereby ensuring the cleanliness of the mica board production workshop and better protecting the mica board production personnel.

[0039] At the same time, by timely removing the dust generated during the processing of the mica board, the cleanliness of the mica board surface is ensured, and the dust is prevented from adhering to the surface of the mica board and affecting the product quality, resulting in product defects.

[0040] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
