Description

Technical Field

[0001] The utility model relates to a milling device, in particular to a milling device for an elevated floor which can automatically mill the ejector pin structure of the elevated floor. Background Art

[0002] Today, elevated floors are widely used in many places, such as anti-static heavy machine rooms or clean rooms. The elevated floors made of aluminum alloy die-casting are produced through five main processes: mold opening, aluminum melting, die-casting, molding and trimming.

[0003] However, most die-cast elevated floors will have some burrs left over. Therefore, during the installation process, on the one hand, the elevated floors cannot fit tightly together, nor can they fit together with the platform frame. On the other hand, it is not conducive to installation, and there are certain risks and safety concerns.

[0004] If the surfaces of the formed elevated floors are manually processed, workers need to transport the elevated floors in batches to the corresponding processing sites for processing. Not only is the production process discontinuous and the production efficiency low, but each processing also wastes a lot of manpower and is time-consuming and labor-intensive.

[0278] It should be additionally explained that, in the above content, the first height H1, the second height H2, the third height H3, the fourth height H4 and the fifth height H5 can be the same or different heights. In addition, the first spacing D1, the second spacing D2, the third spacing D3, the fourth spacing D4 and the fifth spacing D5 can be the same or different spacing distances.

[0279] Please refer to Fig.16 as well as Fig.17 As shown, in this second embodiment, the fifth milling cutter body 821, the sixth milling cutter body, the seventh milling cutter body and the eighth milling cutter body can be respectively actuated by a control device 91, and the control device 91 is a hydraulic control device or a pneumatic control device. Here, the sixth milling cutter body, the seventh milling cutter body and the eighth milling cutter body are the same as the fifth milling cutter body 821, and no further description is given here.

[0280] That is to say, when the milling operation process starts, the fifth transmission device 86 causes the first milling cutter body 821 to perform rotational milling, and the depth of the milling performed by the fifth milling cutter body 821 is controlled by the control device 91. The milling operation process further includes a sixth transmission device, a seventh transmission device, and an eighth transmission device, and the sixth transmission device, the seventh transmission device, and the eighth transmission device are all the same as the fifth transmission device 86, and no further description is given here. The sixth transmission device causes the sixth milling cutter body to perform rotational milling, and the depth of the milling performed by the sixth milling cutter body is controlled by the control device 91; the seventh transmission device causes the seventh milling cutter body to perform rotational milling, and the depth of the milling performed by the seventh milling cutter body is controlled by the control device 91; the eighth transmission device causes the eighth milling cutter body to perform rotational milling, and the depth of the milling performed by the eighth milling cutter body is controlled by the control device 91.

[0281] Please refer to Fig.16As shown, in addition, the milling equipment 14 of the elevated floor also includes a human-machine interface control platform 10, through which processing values ​​are input in the form of a programmable logic controller (PLC). The human-machine interface control platform 10 and the conveying device 3, the fifth milling ejector device 8, the sixth milling ejector device 11, the seventh milling ejector device 12, the eighth milling ejector device 13 and the control device 91 are all interconnected in telecommunication to control the operation of the milling operation processing of the milling equipment 14 of the elevated floor.

[0282] Please refer to the following additional information Fig.17 As shown, the main difference between the above two embodiments is that the milling equipment 14 of the elevated floor of the second embodiment does not need to use the damper, the stroke adjuster and the stroke contactor. That is to say, in the second embodiment, because a back-pressure exhaust valve 8213 is further provided at an intake flow passage 8212 connected to an intake valve 8211 of the fifth milling cutter body 821, by adopting a method of controlling air pressure, the damper 522, the stroke adjuster 523, the first stroke contactor 525 and the second stroke contactor 526 are not required, and the back-pressure exhaust pressure of the back-pressure exhaust valve 8213 is set at 6.9 to 7.5 kilograms per square centimeter, and when the pressure of the intake valve 8211 is set at 5 to 6.5 kilograms per square centimeter, the vibration of the fifth milling cutter body 821 can be reduced, and the manufacturing cost can be reduced. That is to say, when the back pressure exhaust pressure of the back pressure exhaust valve 8213 is preset to be greater than the intake pressure, during operation, if the intake pressure is greater than the back pressure exhaust pressure setting value, the gas enters from the intake flow duct 8212 and is discharged from the back pressure exhaust valve 8213, thereby avoiding defects in the elevated floor 2 caused by excessive surface pressure, reducing the vibration of the fifth milling cutter body 821, and reducing manufacturing costs.

[0283] Please refer to the following additional information Fig.17 and Fig.18 , which is a structural schematic diagram and a partial cross-sectional view of the fifth milling cutter body, the fifth milling cutter body 821 includes a synchronous wheel 92, a spline 93, a push rod 97, a spindle 98, a sleeve 99 and a milling cutter 100, the push rod 97 has a first accommodating space 971, and the spindle 98 is located in the first accommodating space 971. The sleeve 99 is a hollow structure and is movably connected to the spline 96. The milling cutter 100 is connected to the spindle 98, and the milling cutter 100 is located in the sleeve 99. The synchronous wheel 95 drives the spline 96 to rotate.
