[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] Please refer to the attached Figure 1-4The utility model provides a position-adjustable milling machine protective cover, comprising a milling machine body 1 and a base 2. The bottom of the milling machine body 1 is fixedly installed in the middle of the top of the base 2. A milling cutter 3 and a workbench 4 are arranged on the top of the milling machine body 1. It should be noted that the specific structures of the milling machine body 1, the milling cutter 3 and the workbench 4 and the principle that the milling cutter 3 processes the material on the workbench 4 are all well-known technologies to those skilled in the art, so they will not be described in detail. The top ends of the base 2 are connected with protective components through adjustment components, and the protective components are symmetrically arranged on both sides of the milling cutter 3 and the workbench 4.

[0021] The adjustment component includes two laterally arranged mobile bases 5, the bottoms of the two mobile bases 5 are symmetrically fixedly installed on the two ends of the top of the base 2, the two mobile bases 5 are symmetrically distributed on both sides of the milling machine body 1, and the ends of the two mobile bases 5 away from the milling machine body 1 are fixedly installed with servo motors 6. It should be noted that in the utility model, the two servo motors 6 are electrically connected to the external 220V mains electricity, and the two mobile bases 5 are rotatably connected with screw rods 7. The output shaft of the servo motor 6 passes through the end of the mobile base 5 away from the milling machine body 1, and the output shaft of the servo motor 6 is fixedly connected to the end of the screw rod 7. Therefore, when the servo motor 6 is running, it can drive the screw rod 7 set inside the mobile base 5 to rotate forward and reversely. The surface of the screw rod 7 is threadedly connected with a moving block 8, and the moving block 8, the top of each of the limit slides 9 is vertically fixedly installed, and the top of each of the movable bases 5 is horizontally provided with a strip limit hole 10, and the top of each of the limit slides 9 vertically passes through the strip limit hole 10, and the surface of each of the limit slides 9 is in contact with the hole wall of the strip limit hole 10, so under the limiting action of the strip limit hole 10, the limit slide 9 can reciprocate linearly, so when the servo motor 6 drives the screw rod 7 to rotate forward and reversely, the movable block 8 threadedly connected to the surface of the screw rod 7 can be converted from rotational motion to linear reciprocating motion, that is, the two movable blocks 8 can be controlled to move toward or in reverse, and the top of each of the limit slides 9 is fixedly installed with a movable plate 11, and the top of each of the movable plates 11 is vertically fixedly installed with a bracket 12, that is, the movable plate 11 and the bracket 12 can synchronously move toward or in reverse;

[0022] The protection component includes two protection covers 13, which are symmetrically distributed on both sides of the milling cutter 3 and the workbench 4. The side ends of the two protection covers 13 are fixedly installed on the opposite surfaces of the two brackets 12, so the two protection covers 13 can move towards each other or in the opposite direction. Therefore, when the protection covers 13 need to be opened for loading and unloading, the two protection covers 13 can be controlled to move in the opposite direction and open automatically. When the milling cutter 3 processes the material on the workbench 4, the two protection covers 13 can be controlled to move towards each other and close automatically, so that the space around the milling cutter 3 and the workbench 4 can be effectively blocked, thereby realizing the protection function to improve safety. In addition, the protection covers 13 can be opened and closed automatically, that is, the position can be automatically adjusted, and manual loading and unloading is unnecessary, and the operation is simple and convenient.

[0023] A glass window 14 is provided at the center of the front end of the protective cover 13 , which allows technicians in this field to observe the real-time processing of the material by the milling cutter 3 inside the protective cover 13 .

[0024] The use process of the utility model is as follows: when a technician in this field loads and unloads materials onto the workbench 4 and needs to open the protective cover 13, the two servo motors 6 can be controlled to operate. When the servo motor 6 is operating, the screw rod 7 set inside the mobile base 5 can be driven to rotate. Under the joint limiting action of the bar-shaped limiting hole 10 and the limiting slide plate 9, when the servo motor 6 operates to drive the screw rod 7 to rotate, the moving block 8 threadedly connected to the surface of the screw rod 7 can be converted from rotational motion to linear motion, and the two moving blocks 8 can be controlled to move in the opposite direction, so that the two brackets 12 and the two protective covers 13 can be controlled to move in the opposite direction synchronously through the moving plate 11, that is, the two protective covers 13 are automatically opened;

[0025] When the milling cutter 3 processes the material on the workbench 4 and the protective cover 13 needs to be closed, the technicians in this field can control the two servo motors 6 to rotate in opposite directions, thereby controlling the two protective covers 13 to move toward each other, that is, the two protective covers 13 are automatically closed, so that the space around the milling cutter 3 and the workbench 4 can be effectively blocked, thereby realizing the protection function to improve safety, and the protective cover 13 can be opened and closed automatically, that is, the position can be automatically adjusted, without manual loading and unloading, and the operation is simple and convenient.

[0026] The above is only a preferred embodiment of the utility model. Any person skilled in the art can modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
