[0002] Metal mesh is a common decorative product on the market, and its production process needs to be continuously improved, especially for multi-array hole operations. The traditional drilling or milling processing can usually only process a single hole, and then use the workbench to displace and replace the array holes at equal distances, which is extremely inefficient. The existing processing solution is to use multiple motors to drill or mill holes simultaneously, but holes with different specifications and spacings require adjusting the spacing of multiple motors each time, which is extremely inconvenient. For this reason, we need to specially design a mechanism to realize variable spacing processing of array holes, improve production efficiency, and adapt to array hole processing with a variety of spacings to produce a variety of sheet materials. Utility Model Content

[0003] The purpose of the utility model is to solve the problems of low efficiency of existing single-axis drilling array holes or milling array holes on metal sheets, or single spacing adjustment of multi-motor drilling array holes or milling array holes, and inconvenience in spacing adjustment after changing the spacing specifications. We propose an efficient milling array hole mechanism.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An efficient milling array hole mechanism comprises a plurality of drilling and milling components and a positioning slide block, a slide seat, end covers arranged on both sides of the slide seat, an electric screw pair, and a distance-adjusting connecting rod component.

The lower end of the spindle is clamped with a clamping claw to hold the drilling and milling cutter. The rotating motor is positioned and matched with a positioning slider. Slide bars are arranged on both sides of the positioning slider. The slide bars cooperate with the slide grooves provided on the inner side of the slide seat to slide horizontally and linearly. The two sides of the slide seat are clamped and positioned by end covers and are connected and locked by connecting pieces.

[0007] The electric screw pair is arranged in the end cover, and includes a servo motor and a screw pair. The screw pair is movably connected to the nearest positioning slider, and driven by the servo motor, the screw of the screw pair is connected to the positioning slider and is pulled horizontally and linearly.

[0008] The distance-adjusting connecting rod assembly is arranged between several positioning sliders, including several groups of first bearings and second bearings, first connecting rods and second connecting rods arranged on the central axis of the upper end of the positioning sliders. The first connecting rod passes through the first bearing horizontally, and the second connecting rod passes through the second bearing horizontally. The two ends of the first connecting rod are movably hinged with the two ends of the adjacent second connecting rod, and the first connecting rod and the second connecting rod have the same length. At this point, the distance adjustment between all the positioning sliders is kept synchronized and equal.

[0009] Furthermore, an insert block matching the cross section of the slide groove is provided on one side of the end cover facing the slide seat.

[0010] Furthermore, the insert block is provided with a threaded hole, and the upper parts of both ends of the slide seat are provided with through holes, and screws are passed through the through holes and screwed and locked with the threaded holes, so that the end cover and the slide seat are stably connected.
