Description

Technical Field

[0001] The present invention relates to a polishing machine and its liquid circulation device, belonging to the technical field of numerical control machining. Background Art

[0002] 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 increases the floor area of the machine tool, and arranging the liquid path on the machine tool bed also complicates the structure of the machine tool. For example, in the case of a polishing machine with an integrated structure, when a problem occurs in the liquid circulation device, the whole machine needs to be overhauled, which affects the production progress. At the same time, it is difficult for the existing liquid circulation device of the polishing machine to fully stir the polishing liquid, thereby affecting the polishing effect. Moreover, during the existing polishing process, the auxiliary liquid directly flows into the equipment base, making the whole equipment in a humid state, which easily accelerates the corrosion and oxidation of the equipment. In addition, only using the method of spraying the polishing liquid easily causes problems such as uneven spraying and insufficient spraying amount, resulting in longer polishing time and poor polishing effect. Summary of the Invention

[0003] The present invention provides a polishing machine and its liquid circulation device, aiming to solve at least one of the technical problems existing in the prior art. For example, the present invention proposes a polishing machine and its liquid circulation device, which can improve the processing effect and reduce the floor area.

[0017] The polishing machine and its liquid circulation device of the present invention can reduce the floor area and improve the processing effect. The workbench is fixed to the front side of the bed body assembly, the liquid supply assembly is arranged on the bed body assembly, and the liquid outlet for recovering the liquid after processing is arranged in front of the workbench. The auxiliary liquid flows from the liquid storage tank to the workpiece and then directly flows back to the liquid storage tank without passing through the three-axis moving structure of the processing equipment, which can reduce the floor area of the whole machine, reduce the complexity of the liquid path layout, and make the whole machine miniaturized. The liquid storage tank is provided with a circular inner cavity, and the stirrer is arranged on one side of the liquid storage tank. When the circulation pump works, part of the water in the tank is sprayed out from the pipe joint, so that the liquid in the tank rotates and flows, which is beneficial to realize uniform stirring. The liquid receiving tray is directly fixed on the workbench, and the workpiece is arranged in the cavity of the liquid receiving tray. The auxiliary liquid sprayed on the processed workpiece directly flows away from the liquid outlet, which can reduce the influence of the auxiliary liquid on the bed body. The bottom wall and the side wall of the liquid receiving tray are both provided with liquid outlets, and one of the liquid outlets can be selected to be opened according to needs, so that only the workpiece can be sprayed, or the workpiece can be sprayed and soaked at the same time. And the workbench is inclined, which is beneficial to quickly drain the auxiliary liquid in the processing equipment. Description of the Drawings

Further, connecting portions 331 are arranged on both the front side and the rear side of the cushion block 330. One connecting portion 331 is connected to the lower end of a fixed bracket 515 of the liquid receiving assembly 510 (referring to Figure 5)。In some specific embodiments, the liquid receiving assembly 510 is provided with four fixing brackets 515, two of the fixing brackets 515 are arranged on the left side of the liquid receiving tray 513, and the other two fixing brackets 515 are arranged on the right side of the liquid receiving tray 513. Correspondingly, two cushion blocks 330 are arranged on the workbench 300. One of the cushion blocks 330 is arranged on the left side of the workbench 300, and the cushion block 330 is provided with two connecting parts 331. The two connecting parts 33 are respectively located on the front side and the rear side of the cushion block 330, and the two connecting parts 33 are connected to the two fixing brackets 515 on the left side.

[0063] In some embodiments, referring to Figure 4 and Figure 5 , the liquid supply mechanism 500 is provided with a liquid guide member 530. The liquid guide member 530 is connected to the outer edge of the workbench 300. The liquid guide member 530 is arranged above the recovery port 522 of the liquid supply assembly 520 and below the liquid outlet 512 of the liquid receiving assembly 510 to divert the auxiliary liquid on the workbench 300 into the recovery port 522 of the liquid supply assembly 520 and divert the auxiliary liquid flowing out of the liquid receiving assembly 510 into the liquid supply assembly 520. Further, referring to Figure 4 and Figure 10 , the liquid guide member 530 is provided with a liquid guide groove and a converging port 531. The upper end of the side wall of the liquid guide groove is connected to the outer edge of the workbench 300. The converging port 531 is arranged in the middle of the bottom wall of the liquid guide groove and above the recovery port 522. It can be understood that the bottom wall of the liquid guide groove slopes downward from both sides towards the converging port 531.

[0064] In some embodiments, the liquid supply assembly 520 includes a liquid storage tank 523 and a stirrer 524. The stirrer 524 is arranged on one side of the cavity of the liquid storage tank 523. The liquid storage tank 523 has a cylindrical structure. The liquid storage tank 523 is provided with a pipe joint 527 for connecting to the circulation pump 526. Thus, when the circulation pump 526 is working, a part of the auxiliary liquid is ejected from the pipe joint 527 to make the auxiliary liquid in the liquid storage tank 523 flow and rotate. Referring to Figure 7 and Figure 9 , in the liquid supply assembly 520, when the circulation pump 526 is working, a part of the liquid is ejected from the pipe joint 527 to make the liquid in the liquid storage tank 523 flow. After the auxiliary liquid in the liquid storage tank 523 is sprayed from the liquid spraying port 521 to the workpiece through the liquid supply pipeline, it flows out from the liquid outlet 512 after passing through the liquid receiving tray 513 into the liquid guide member 530, and then flows into the filter basket 525 from the converging port 531 of the liquid guide member 530. After being filtered, it flows into the liquid storage tank 523 from the recovery port 522, and the stirrer 524 stirs the auxiliary liquid in the liquid storage tank 523.

[0065] In some embodiments, the bed body assembly 100 is provided with a diversion groove 140, and the outlet of the diversion groove 140 assists the liquid flow towards the liquid supply assembly 520, so that the auxiliary liquid splashed onto the bed body assembly 100 can be recovered to the liquid supply assembly 520 through the diversion groove 140. Refer to Figure 3 , Figure 4 and Figure 10 , the diversion groove 140 is arranged below the liquid receiving assembly 510 and surrounds the periphery of the bed body assembly 100. Specifically, the diversion groove 140 includes a first diversion section 141 and two second diversion sections 142. The first diversion section 141 is arranged between the bed body base 120 and the bed body base 130, and the two second diversion sections 142 are arranged on the left and right sides of the workbench 300. One of the outlets of the two second diversion sections 142 is communicated with the two outlets of the first diversion section 141, and the other outlet of the two second diversion sections 142 is arranged above the liquid supply assembly 520. Further, 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 communicated with the outlets of the second diversion sections 142.
