Description

Technical Field

[0001] The utility model relates to the technical field of CNC milling machines, and particularly relates to a CNC milling machine capable of removing dust. Background Art

[0002] A CNC milling machine is a milling machine controlled by digital signals of an electronic computer. It is an automatic processing equipment developed on the basis of a general milling machine. CNC milling machines are divided into two categories: those without a tool magazine and those with a tool magazine. It has the characteristics of good flexibility, high machining accuracy, stable and reliable machining quality, high degree of production automation, and high production efficiency.

[0003] In the application number: CN202122463941.7, a CNC milling machine with a dust removal function is disclosed, which improves the dust suction range of the dust suction seat, avoids dead corners during dust removal, and improves the dust removal effect of the CNC milling machine. However, the above design still has deficiencies. The two sides of the mounting frame are open, which will affect the dust suction effect of the dust suction seat. When the device is working, the debris on the workpiece is easy to splash, and thus there are potential safety hazards.

[0004] Therefore, we propose a CNC milling machine capable of removing dust. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a CNC milling machine capable of removing dust. Through the combined use of two sealing plates, a relatively closed processing space can be formed inside the mounting frame, which is convenient for the dust suction seat to perform dust reduction operations. At the same time, it can also improve the safety of the device body and avoid the splashing of debris during workpiece processing, and can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A CNC milling machine capable of removing dust includes a device body and a mounting frame. The mounting frame is fixedly assembled on the device body. A sealing component is sleeved outside the mounting frame. The sealing component includes a sealing plate, an observation plate, a support frame, a top plate, a protective shell, a motor, a threaded rod, a moving block, a cross plate, a connecting piece, and a first bolt.

[0008] Chutes for installing the sealing plates are provided on both sides of the mounting frame. Two sealing plates are arranged relatively parallel. An installation channel for installing the support frame is provided between the two sealing plates. The installation channel is located at the top of the mounting frame. The bottom end of the support frame is fixedly connected to the center of the top end of the mounting frame. The top end of the support frame is fixedly connected with a top plate for installing the motor. A clamping groove for installing the protective shell is provided at the outer edge of the upper end surface of the top plate. The protective shell is sleeved on the motor.

[0009] By adopting the above technical solution, the motor drives the threaded rod to rotate. Through the threaded fit between the threaded rod and the moving block, the moving block can push the two sealing plates downward on both sides of the mounting frame through the cross plate until the bottom end of the sealing plate contacts the upper end surface of the outer bottom plate of the device body, forming a relatively enclosed processing space inside the mounting frame, facilitating the dust reduction operation of the dust suction seat, and improving the safety of the device body at the same time, avoiding the splashing of chips during workpiece processing.

[0010] Specifically, a cavity for installing the threaded rod is provided inside the support frame, and a moving block sleeved on the threaded rod is also provided in the cavity.

[0011] Specifically, the bottom end of the threaded rod is rotatably connected to the inner wall of the bottom end of the cavity, and the top end of the threaded rod passes through the top plate and is connected to the output shaft of the bottom end of the motor.

[0012] Specifically, two relatively parallel connecting pieces are jointly buckled at the top ends of the two sealing plates. The connecting pieces are fixedly connected to the upper part of the sealing plates through first bolts, and the support frame is located between the two connecting pieces.

[0013] Specifically, cross plates are fixedly welded at the middle positions of both ends of the moving block, and one end of the cross plate far from the moving block is clamped with the connecting piece.

[0014] Specifically, one side of the sealing plate is slidably connected to the mounting frame, and an observation plate is fixedly inlaid at the middle position of one side of the sealing plate.

[0015] Advantages of the present utility model:

[0016] (1) For the numerically controlled milling machine capable of dust removal of the present utility model, the motor drives the threaded rod to rotate. Through the threaded fit between the threaded rod and the moving block, the moving block can push the two sealing plates downward on both sides of the mounting frame through the cross plate until the bottom end of the sealing plate contacts the upper end surface of the outer bottom plate of the device body, forming a relatively enclosed processing space inside the mounting frame, facilitating the dust reduction operation of the dust suction seat, and improving the safety of the device body at the same time, avoiding the splashing of chips during workpiece processing;

[0017] (2) For the numerically controlled milling machine capable of dust removal of the present utility model, the sealing component has the advantages of being easy to install, and at the same time, the sealing component can be used flexibly.
