Description

Polishing machine and liquid circulation device thereof

Technical Field

The invention relates to a polishing machine and a liquid circulation device thereof, belonging to the technical field of numerical control machining.

Background Art

Existing processing equipment is usually equipped with a liquid circulation device to spray auxiliary liquid during processing and recycle the auxiliary liquid. However, the existing liquid circulation device will cause the machine tool to occupy an increased area, and the arrangement of the liquid circuit on the bed will also complicate the structure of the machine tool. For example, in the case of a polishing machine with an integrated structure, when there is a problem with the liquid circulation device, the entire machine needs to be overhauled, which affects the production progress. At the same time, the liquid circulation device of the existing polishing machine is difficult to fully stir the polishing liquid, which in turn affects the polishing effect. In addition, in the existing polishing process, the auxiliary liquid directly flows into the base of the equipment, making the entire equipment in a wet state, which is easy to accelerate the corrosion and oxidation of the equipment. In addition, only the method of spraying the polishing liquid is used, which is prone to problems such as uneven spraying and insufficient spraying, resulting in prolonged polishing time and poor polishing effect.

Summary of the invention

The present invention provides a polishing machine and a liquid circulation device thereof, aiming to solve at least one of the technical problems existing in the prior art. For example, the present invention provides a polishing machine and a liquid circulation device thereof, which can improve the processing effect and reduce the occupied area.

The auxiliary liquid in the liquid storage tank 523 is sprayed from the liquid spray port 521 to the processed workpiece through the liquid supply pipeline, and then flows out from the liquid outlet 512 to the liquid guide member 530 after passing through the liquid receiving plate 513, and then flows into the filter basket 525 from the converging port 531 of the liquid guide member 530, and after being filtered, it flows into the liquid storage tank 523 from the recovery port 522, and the auxiliary liquid in the liquid storage tank 523 is stirred by the agitator 524.

In some embodiments, the bed assembly 100 is provided with a guide groove 140, and the auxiliary liquid flows to the liquid supply assembly 520 at the outlet of the guide groove 140, so that the auxiliary liquid splashed on the bed assembly 100 can be recovered to the liquid supply assembly 520 through the guide groove 140. Referring to Figures 3, 4 and 10, the guide groove 140 is arranged below the liquid receiving assembly 510 and surrounds the periphery of the bed assembly 100. Specifically, the guide groove 140 includes a first guide section 141 and two second guide sections 142, the first guide section 141 is arranged between the bed base 120 and the bed base 130, the two second guide sections 142 are arranged on the left and right sides of the workbench 300, one of the outlets of the two second guide sections 142 is connected to the two outlets of the first guide section 141, and the other outlet of the two second guide sections 142 is arranged above the liquid supply assembly 520. Furthermore, a liquid guiding member 530 is connected to the outer edge of the workbench 300 , and both sides of the liquid guiding groove of the liquid guiding member 530 are in communication with the outlet of the second guiding section 142 .
