[0013] It should be noted that when an element is referred to as "fixed to" or "set to" another element, it can be directly on another element or there can be a middle element.When an element is considered "connected" to another element, it can be directly connected to another element or there can be a middle element.The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs.The terms used in the specification of the utility model herein are only for the purpose of describing the specific embodiments and are not intended to limit the utility model.The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0015] As Figs. 1-2As shown, a unmanned aerial vehicle rack milling equipment, including gantry 1, milling head 2, workbench 3 and fixture 4, the milling head 2 is vertically movable mounted on gantry 1, and is located above the workbench 3, the milling head 2 is integrated with liquid cooling nozzle 21, the workbench 3 is provided with a plurality of parallel spaced grooves 31 on the table surface, the fixture 4 is installed on the workbench 3, the bottom of the fixture 4 is provided with a sliding block 41 matched with the sliding groove 31, there is a gap between the bottom of the sliding block 41 and the groove bottom of the sliding groove 31, the upper part of the fixture 4 is provided with a positioning clamp jaw 42 for clamping workpiece, the front end and the rear end of the workbench 3 are provided with a collecting box 5, the collecting box 5 is communicated with the sliding groove 31, and the collecting box 5 is provided with a filter screen. Specifically, in this embodiment, the gantry 1 is used as the mounting carrier of the milling head 2, which drives the milling head 2 to displace, so that it can mill on the surface of the workpiece (not shown in the figure), that is, the unmanned aerial vehicle rack. The milling head 2 is vertically installed, and the driving member capable of driving the milling cutter to displace upward and downward is integrated in the milling head 2, which is convenient for adapting to irregular unmanned aerial vehicle racks and avoiding the collision of the milling cutter with the undulating rack. The driving member can be a lead screw assembly, or an oil cylinder, or an air cylinder, etc., which is not limited here. The milling head 2 is integrated with a liquid cooling nozzle 21, which is used for liquid cooling of the milling cutter and the workpiece, and flushes down the chips generated during processing, and converges into the sliding groove 31 of the workbench 3. In order to prevent the water flow from being blocked by the sliding block 41 of the fixture 4 installed on the workbench 3, we design a gap between the sliding block 41 and the groove bottom of the sliding groove 31, so that the water flow can pass normally and be discharged into the collecting box 5 to complete the collection. The collecting box 5 is integrated with a filter plate, which can preliminarily filter the chips carried in the water flow, and facilitate the recycling of the liquid. The fixture 4 is clamped on the workbench 3 through the sliding block 41 arranged at the bottom, so that the fixture 4 can carry the workpiece to displace along the sliding groove 31, adjust the position, and facilitate the processing. We detachably arrange the positioning clamp jaw 42 on the fixture 4, and the positioning clamp jaw 42 is used for clamping workpieces of different shapes and sizes, without the need to replace the fixture 4 as a whole, thereby reducing the operation difficulty.

[0016] Specifically, the side wall of the sliding groove 31 is concave, and the side wall of the sliding groove 31 is matched with the side of the sliding block 41 to support.

[0017] Specifically, the sliding groove 31 is high in the middle and low at both ends, and after the water flow enters the sliding groove 31, it flows to both ends of the sliding groove 31 under the action of gravity, enters the collecting box 5, and completes the filtering and collection.

[0018] As Figs. 1-2As shown in the drawings, the gantry 1 comprises a frame body 11 and a horizontal moving screw assembly 12, the horizontal moving screw assembly 12 is installed on the top of the frame body 11, the top of the frame body 11 is provided with a guide plate 111, the milling head 2 is movably connected with the guide plate 111, and the horizontal moving screw assembly 12 drives the milling head 2 to make reciprocating linear motion along the guide plate 111.

[0019] As shown in the drawings, Figs. 1-2 The bottom of the milling head 2 is provided with a brush ring 22 around the milling cutter, and a plurality of liquid cooling nozzles 21 are arranged around the brush ring 22. Specifically, the brush ring 22 acts on the surface of the workpiece to press the workpiece, prevents the debris generated during machining from splashing out, and the liquid cooling nozzles 21 flush the workpiece and the milling cutter to cool the workpiece and the milling cutter and improve the service life of the milling cutter.

[0020] The above-mentioned embodiments only express several embodiments of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent scope. It should be pointed out that for ordinary skilled person in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
