Description

Technical Field

[0001] The utility model belongs to the technical field of milling machine processing, and in particular relates to an automatic lubrication device for a milling machine tool. Background Art

[0002] Milling machines mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. Usually, the main motion is the rotation of the milling cutter, and the movement of the workpiece and the milling cutter is the feed motion. In addition to milling planes, grooves, gear teeth, threads and spline shafts, it can also process more complex surfaces. It is more efficient than planing machines and is widely used in mechanical manufacturing and repair departments. The lubrication device of the milling machine occupies a very important position in the whole machine tool. It not only has a lubricating effect, but also a cooling effect to reduce the influence of thermal deformation of the machine tool on the processing accuracy.

[0003] The existing milling machine lubrication device is fixed on one side of the tool through a liquid spray hose, which lubricates and cools the tool head and cutting surface when processing the workpiece. However, the liquid spray hose only has the function of moving up and down. For the processing of some complex or large workpieces, the lubricating liquid sprayed by the hose cannot completely cover the workpiece or cutting surface, forming a lubrication dead angle. In addition, since most milling machines have no baffles around them, in order to prevent liquid splashing and polluting the environment, it is also particularly important to control the flow rate of the lubricating liquid.

[0007] The two sides of the regulating tube are fixedly connected with injection tube 1, the regulating tube is fixedly connected with a connecting block through injection tube 2 which is symmetrically fixedly connected at the bottom, a sliding plate 2 is slidingly assembled at the bottom of the inner wall of the regulating tube and located at the top of the injection tube 2, the sliding plate 2 is fixedly connected with sliding plate 1 through connecting rod 2, the sliding plate 1 is fixedly connected with connecting ring 1 through connecting rod 1, the bottom of the connecting block is rotatably connected to a rotating bin, the outer wall of the rotating bin is fixedly connected with teeth in an array, and the gear 1 is meshingly connected with the teeth.

[0008] Fixed blocks are fixedly connected to both sides of the structure bin.

[0009] The regulating tube is fixedly connected to the fixing block via a liquid injection tube 1.
