[0002] A polishing machine, also known as a grinding machine, is often used for mechanical grinding, polishing and waxing. Its working principle is that an electric motor drives a polishing disc installed on the polishing machine to rotate at a high speed. Due to the combined action of the polishing disc and the polishing agent and the friction with the surface to be polished, the purpose of removing paint surface pollution, oxide layer and shallow scratches can be achieved.

[0003] However, during the polishing process of products using the existing polishing machine, oil-water mixing is likely to occur. On the one hand, this leads to waste of the polishing liquid, and on the other hand, it will also cause corrosion to the machine platform, resulting in crystallization of the machine platform. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a polishing equipment facilitating oil-water separation, which can solve the problems of easy pollution of the polishing liquid and easy crystallization and corrosion of the machine platform existing in the existing polishing equipment by isolating and separately collecting the polishing liquid and the lubricating oil.

[0005] To achieve the above purpose, the technical solution provided by the utility model is as follows:

[0006] The utility model provides a polishing equipment facilitating oil-water separation, including a base. An X-axis tray extending horizontally is arranged on the base. A Y-axis tray is slidably installed on the X-axis tray along the horizontal direction. A workbench is slidably installed on the Y-axis tray along the vertical direction, and a polishing fixture assembly station is arranged thereon.

[0007] A cross beam parallel to the X-axis tray and vertically spaced is arranged on one side of the X-axis tray on the base. The cross beam is used for assembling a grinding disc assembly. The area between the cross beam and the X-axis tray on the upper surface of the base is recessed downward to form a water receiving tray for collecting the polishing liquid falling during the polishing process. The X-axis tray and the Y-axis tray are both recessed downward to form oil collecting grooves for collecting the lubricating oil.

[0008] On the one hand, the utility model provides a special water receiving tray and oil collecting grooves to separately collect the polishing liquid and the lubricating oil. On the other hand, the layout of the polishing equipment is optimized, especially the X-axis tray and the cross beam are vertically spaced, and the water receiving tray is located on the surface of the base between the X-axis tray and the cross beam. Thus, the polishing liquid and the lubricating oil can be physically separated in space and collected respectively through the water receiving tray and the oil collecting grooves, realizing the effective separation of the polishing liquid and the lubricating oil. Therefore, it is beneficial to avoid pollution of the polishing liquid and corrosion and crystallization of the machine platform.

[0009] Meanwhile, through the relative sliding installation between the X-axis tray, the Y-axis tray and the workbench, the position of the workpiece can also be adjusted, which is convenient for aligning the workpiece with the polishing disc and can polish different positions on the workpiece.

[0010] Furthermore, in order to facilitate the timely discharge of the polishing liquid in the water receiving tray, the water receiving tray is of a conical structure, and a drain hole is provided near the conical bottom in the water receiving tray. The drain hole is communicated with the outside of the base through a drain pipe to form a drainage channel.

[0011] Furthermore, a water pump is provided on the drainage channel.

[0020] Furthermore, a motor mounting groove is processed on the base, the bottom of the Z-axis motor is located in the mounting groove, the top is fixed by a motor mounting frame, and a protective shell is provided on the outside of the motor mounting frame; the Z-axis motor is connected to the crossbeam transmission through a screw mechanism.

[0021] Furthermore, both the front and rear sides of the crossbeam are provided with vertically distributed protective plates, and the left and right ends of the protective plates extend to the two columns respectively, and the upper and lower ends extend upward from the base surface to the crossbeam. The provision of the protective plates can further prevent the polishing liquid from being sprayed into the oil collecting tank between the two columns, further improving the oil-water separation effect; at the same time, it can also effectively protect the driving mechanism between the crossbeam and the columns.

[0038] It should also be noted that the terms "first", "second", etc. in the specification, claims and above-mentioned drawings of this application are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so as to implement the embodiments of this application described here.

[0039] Combined with Figure 1 , the embodiment of the present utility model provides a polishing device facilitating oil-water separation, including a base 1, an X-axis tray 2, a Y-axis tray 3, a cross beam 6 and a workbench 4, wherein:

[0040] The base 1 serves as the installation foundation of the entire device. The X-axis tray 2 is horizontally installed on the base 1. The Y-axis tray 3 is slidably installed on the X-axis tray 2 in the horizontal direction. The workbench 4 is slidably installed on the Y-axis tray 3 in the longitudinal direction, and a polishing fixture assembly station is provided thereon for the assembly of the polishing fixture 5 and the workpiece. The horizontal and longitudinal positions of the workpiece can be adjusted by the relative sliding between the X-axis tray 2, the Y-axis tray 3, and the workbench 4.

[0041] The cross beam 6 is also horizontally installed on the base 1. It is located on one side of the X-axis tray 2 and is longitudinally spaced relative to the X-axis tray 2. Specifically, in some embodiments, a column 8 is vertically installed on the base 1 on one side of the X-axis tray 2. The cross beam 6 is installed on the base 1 through the column 8, and a grinding wheel assembly installation station is provided on the cross beam 6 for the installation of the grinding wheel assembly 7. In order to facilitate the adjustment of the relative height between the grinding wheel assembly 7 and the workpiece, in this embodiment, it is further preferably that the cross beam 6 is slidably installed on the column 8 in the vertical direction.

[0042] When using an existing polishing device for processing, the polishing liquid is likely to be mixed with the lubricating oil used in the device, such as the lubricating oil of the horizontal and vertical movement drive mechanisms (such as lead screws) and the guiding mechanisms (such as guide rails and sliders). Especially, it is easy to mix on the surface of the base 1, resulting in the pollution of the polishing liquid. At the same time, it will also corrode the machine table, causing the machine table to crystallize.

[0043] Based on this problem, on the one hand, combined with Figure 2 、 Figure 3 , in this embodiment, the upper surface of the base 1 is recessed downward between the cross beam 6 and the X-axis tray 2 to form a water receiving tray 101 (the water receiving tray 101 and the base 1 form an integrated waterproof structure). Both the X-axis tray 2 and the Y-axis tray 3 are recessed downward to form oil collecting grooves. The water receiving tray 101 collects the polishing liquid that drops during the polishing process, and the oil collecting grooves collect the lubricating oil used in the X-axis and Y-axis movement drive mechanisms. Thus, it can effectively prevent the mixing of the lubricating oil and the polishing liquid, which is beneficial to the recycling of the polishing liquid and can also effectively prevent the corrosion of the machine table. On the other hand, in this embodiment, the overall structural layout of the polishing device is also optimized, especially the X-axis tray 2 and the cross beam 6 are longitudinally spaced and are respectively arranged on both sides of the water receiving tray 101, and the water receiving tray 101 and the base are of an integrated structure. Therefore, the spatial layout among the X-axis tray 2, the cross beam 6, and the water receiving tray 101 can be used to further physically separate the polishing liquid and the lubricating oil, which is beneficial to further ensuring the isolation and separation effect.

[0044] In some embodiments, the workbench 4 includes a fixed base and a rotating base rotatably mounted on the fixed base. The fixed base is slidably mounted on the Y-axis tray longitudinally. The polishing fixture assembly station is located on the rotating base, and a rotating shaft (C-axis) for driving the polishing fixture to rotate self is rotatably mounted on the rotating base. The rotating base is driven by a flipping motor to drive the polishing fixture to flip around the B-axis together, so that the B-axis flipping movement of the workpiece can be realized (the B-axis is parallel to the length direction of the X-axis tray and the cross beam, so that the flipping base can drive the polishing fixture and the workpiece to rotate towards or away from the grinding wheel assembly 7 together). The polishing fixture is driven to rotate self by a self-rotating motor, so as to realize the C-axis rotation movement of the workpiece. In order to effectively protect the workbench 4, a protective housing is provided around it. It should be noted that the specific structure of the workbench 4 in this application is not limited, as long as the self-rotation of the workpiece and the flipping movement around the B-axis can be realized simultaneously.

[0045] During the specific polishing process, the Y-axis tray 3 is driven to move horizontally along the X-axis tray 2, the workbench 4 is driven to move longitudinally along the Y-axis tray 3, the cross beam 6 is driven to move up and down in the vertical direction, and the workbench 4 drives the polishing fixture 5 and the workpiece to rotate self or flip around the B-axis together, so that the relative position between the workpiece and the grinding wheel assembly 7 can be adjusted, facilitating the processing of different parts of the workpiece. Especially through the optimized design of the distribution of the five-axis movement, it is also possible to polish the positions such as the corners of the workpiece well, ensuring no dead angle in polishing and effectively improving the polishing accuracy and quality.

[0046] As a further improvement of any embodiment of the present utility model, the water receiving tray 101 is of a conical structure, and a drain hole 102 is provided near the conical bottom in the water receiving tray 101. The drain hole 102 is communicated with the outside of the base 1 through a drain pipe 103 to form a drainage channel, so as to facilitate the drainage of the polishing liquid through the drainage channel.

[0047] In some embodiments, a water pump is provided on the drainage channel.

[0048] A filtering unit for filtering the polishing liquid; and / or

[0050] After being collected by the water receiving tray 101, the polishing liquid is led out through the drainage channel to the polishing liquid circulation treatment device for filtration and / or cooling treatment, so that it can be recycled again, which improves the utilization rate of the polishing liquid and helps save costs. The filtering unit and cooling unit here can directly adopt existing filtering devices and cooling devices, which will not be specifically expanded here.
