Description

TECHNICAL FIELD

[0001] The application relates to the technical field of numerical control machining, in particular to a numerical control milling machine for machining towel rack accessories. BACKGROUND

[0002] Aluminum profiles have good corrosion resistance, light weight, high strength, easy processing and other characteristics, and are widely used in the manufacturing of towel racks and their related accessories in the bathroom industry. When the towel racks and their related accessories are being processed, numerical control milling machines are used to cut and mill them.

[0003] In the prior art, a milling cutter is arranged on the numerical control milling machine, and various complex milling operations are automatically controlled by programming to efficiently complete various complex shape machining tasks of aluminum profiles, such as machining various planes, curved surfaces, grooves and shaped surfaces. Since aluminum is a light metal with good heat conductivity, a large amount of heat is generated when the milling cutter cuts and mills the aluminum profile. If the heat is not dissipated in time, the aluminum profile may deform during the machining process, reducing the machining precision of the towel rack accessories. Therefore, when the milling cutter is machining the aluminum profile, a spraying pipe is usually used to spray cooling liquid to it to dissipate the generated heat in time.

[0004] However, when the spraying pipe sprays the cooling liquid, the cooling liquid collides with the rotating milling cutter, and the cooling liquid is splashed everywhere by the strong centrifugal force, which reduces the overall cleanliness of the milling machine to some extent, and therefore needs to be further improved.

When the sliding block 43 is displaced along the sliding groove 44, the swing assembly 7 forces the free end of the spray pipe 41 to swing towards or away from the central axis of the rotating shaft 3.

[0070] With reference to Figure 9 The sliding block 43 is provided with a through hole 431, and the swing assembly 7 comprises a reversing wheel 71 and a pull rope 72. The annular wheel is rotatably installed on the side wall of the sliding block 43. One end of the pull rope 72 is fixedly connected to the inner wall of the sliding groove 44, and the other end passes through the through hole 431 and is then wound around the outer peripheral wall of the reversing wheel 71 and fixedly connected to the peripheral wall of the spray pipe 41. When the sliding block 43 moves towards the center of the spray seat 4, the pull rope 72 pulls the spray pipe 41, so that the free end of the spray pipe 41 swings towards the central axis of the rotating shaft 3.

[0071] The implementation principle of the embodiment 3 of the application is that, through the arrangement of the pull rope 72, when the sliding block 43 is displaced, the spray pipe 41 swings under the action of the pull rope 72, which can further expand the spraying range of the cooling liquid, and further improve the cooling effect.

[0072] The above is the preferred embodiment of the application, which does not limit the protection scope of the application, therefore: any equivalent changes made according to the structure, shape and principle of the application shall be covered within the protection scope of the application.
