Description

Technical Field

[0001] The utility model relates to polishing equipment, in particular to a plasma polishing machine. Background Art

[0002] The principle of plasma polishing is to adsorb the metal ions that are electrically separated from the workpiece to be polished and the polishing liquid on the surface of the workpiece, so that the current impact on the protrusions of the workpiece to be polished is high and the removal is fast. Through the flow of current, the concave and convex parts are constantly changing, so that the rough surface of the workpiece is gradually flattened, thereby achieving a polishing effect that increases the brightness of the workpiece surface. However, during the polishing process, the material removed from the workpiece surface will form tiny particles and suspend in the polishing liquid. As the concentration of tiny particles increases, impurities are formed that affect the polishing effect. The existing treatment method is to let the polishing liquid stand for two to three days, and these impurities will settle to the bottom. The upper layer of polishing liquid can be extracted and reused, but this requires interrupting production, which will affect the production process and increase storage space and storage costs.

[0040] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0042] like Figures 1 to 6 As shown, the utility model provides a plasma polishing machine, including a body 1, a workpiece mounting frame 2 is slidably provided at the upper end of the body 1 in the vertical direction, a trough body 3 is provided at the lower end of the body 1, a partition 33 is provided in the trough body 3, and the partition 33 separates the trough body 3 into a polishing trough 31 and a filter trough 32, the workpiece mounting frame 2 is located directly above the polishing trough 31, and a plurality of filter devices 6 can be sequentially provided in the filter trough 32 from top to bottom, and the plurality of filter devices 6 can be arranged at intervals up and down, and the interval distance between adjacent filter devices 6 can be adjusted. The filtering device 6 includes two mesh plates 61, and a filter cotton 62 is arranged between the two mesh plates 61; a liquid outlet pipe 5 and a liquid adding pipe 4 are respectively connected between the polishing tank 31 and the filtering tank 32, the liquid outlet end of the liquid outlet pipe 5 is located at the lower part of the polishing tank 31, the liquid inlet end of the liquid outlet pipe 5 is located at the lower end of the filtering device 6 of the filtering tank 32, and the liquid outlet end of the liquid outlet pipe 5 is higher than the liquid inlet end of the liquid outlet pipe 5, a liquid outlet valve 51 is arranged on the liquid outlet pipe 5, the liquid outlet end of the liquid adding pipe 4 is located at the upper end of the filtering device 6 of the filtering tank 32, and a liquid adding pump 41 is arranged on the liquid adding pipe 4. A delivery pump can also be arranged on the liquid outlet pipe 5, and the cleaning liquid can be delivered by the delivery pump.

[0043] The utility model can filter the polishing liquid in the polishing tank 31 by setting a filter tank 32. When the polishing liquid needs to be filtered, the liquid outlet valve 51 is opened. Since the liquid outlet end of the liquid outlet pipe 5 is higher than the liquid inlet end of the liquid outlet pipe 5, the polishing liquid in the polishing tank 31 enters the filter tank 32 through the liquid outlet pipe 5 under the action of gravity. As the polishing liquid continues to enter, since the liquid inlet end of the liquid outlet pipe 5 is located at the lower end of the filter device 6 of the filter tank 32, the polishing liquid will gradually rise. The polishing liquid passes through each filter device 6 in turn, so that a part of the metal impurities in the polishing liquid adheres to the filter cotton 62, and a part is deposited at the bottom of the filter tank 32 due to gravity, thereby realizing the filtering of the polishing liquid; when the polishing liquid in the polishing tank 31 needs to be replaced or recycled, the polishing liquid filtered in the filter tank 32 is passed through the liquid adding pipe 4 by the liquid adding pump 41 and enters the polishing tank 31, thereby realizing rapid filtration and automatic recycling of the polishing liquid without stopping production, and no additional storage space is required.

[0044] Preferably, if Figure 3 As shown, the edge of the mesh plate 61 is folded upward to form a mounting portion, and the two mesh plates 61 are buckled together to form a receiving cavity, and the filter cotton 62 is arranged in the receiving cavity. The filter tank 32 is respectively provided with connecting plates 321 around it, and the mounting portion of the mesh plate 61 is fixed to the connecting plate 321 by bolts. The mounting portion of the mesh plate 61 is fixed to the connecting plate 321 by bolts, so that the mesh plate 61 and the filter cotton 62 can be easily removed from the filter tank 32, so as to replace the filter cotton 62.

[0045] Further preferably, transparent observation windows may be provided on the polishing tank 31 and the filtering tank 32. By providing the transparent observation windows, the liquid levels in the polishing tank 31 and the filtering tank 32 can be observed easily.

[0046] Furthermore, the liquid adding pump 41 may be a quantitative pump. By providing a quantitative pump, the polishing liquid in the filter tank 32 can be quantitatively extracted.

[0047] In the present utility model, specifically, Figure 1 and Figure 5 As shown, the workpiece mounting frame 2 includes a cantilever 21 and a hanger 22. The hanger 22 is a hook structure for hanging the workpiece to be polished thereon. The hanger 22 is inserted through the cantilever 21. A slide groove 11 is provided on the rear wall of the machine body 1 in the vertical direction. A lead screw 8 is provided on the rear part of the machine body 1 in the vertical direction. A slider 7 is threadedly connected to the lead screw 8. One end of the cantilever 21 passes through the slide groove 11 and is fixedly connected to the slider 7. One end of the lead screw 8 is connected to a motor 9. During polishing, by starting the motor 9, the motor 9 drives the lead screw 8 to rotate. The rotation of the lead screw 8 drives the slider 7 to move downward, thereby driving the cantilever 21 to move downward along the slide groove 11, thereby causing the hanger 22 on the cantilever 21 to move downward and move it into the polishing groove 31, thereby polishing the workpiece on the hanger 22.

[0048] Furthermore, if Figure 6 As shown, a fixing plate 23 is provided above the hanger 22, a mounting sleeve 24 is fixed above the fixing plate 23, a mounting groove 241 is provided in the mounting sleeve 24, and the cantilever 21 is penetrated in the mounting groove 241. By providing the mounting sleeve 24, the hanger 22 can be conveniently installed on the cantilever 21.

[0049] Furthermore, if Figure 6As shown, a latch 25 is movably provided on the installation sleeve 24, a slot 242 connected to the installation slot 241 is provided in the installation sleeve 24, a baffle 251 is provided on the latch 25, a spring 252 is provided on the outer surface of the latch 25, the baffle 251 and the spring 252 are both located in the slot 242, a socket 210 is provided at the upper end of the cantilever 21, and the insertion end of the latch 25 slides through the slot 242 and is inserted into the socket 210. The hanger 22 is inserted into the cantilever 21 through the mounting groove 241 in the mounting sleeve 24. However, this connection method cannot relatively fix the hanger 22 and the cantilever 21, so that the hanger 22 may shake during the polishing process, thereby causing poor contact between the polishing surface on the workpiece to be polished and the polishing liquid, resulting in poor polishing effect. Therefore, by providing a pin 25, the hanger 22 and the cantilever 21 can be quickly fixed and disassembled, and the hanger 22 and the cantilever 21 can be kept relatively stable, so that the polishing surface on the workpiece to be polished and the polishing liquid are in good contact, and the polishing effect is good.

[0050] In some embodiments, the surface of the hanger 22 may be coated with an elastic layer, which may have a buffering effect to prevent rigid collision damage. Optionally, the area adjacent to the lead screw 8 on the rear wall of the body 1 may be distributed with height scale lines, which can facilitate the determination of the height position of the cantilever 21. The cantilever 21 may be provided with scale lines distributed along the length direction of the cantilever 21, which can facilitate the determination of the position of the hanger 22 on the cantilever 21.

[0051] Optionally, an anti-dropping screw hole can be provided on the end of the cantilever 21 away from the screw 8. The anti-dropping screw hole can be provided adjacent to the end of the cantilever 21 away from the screw 8. An anti-dropping bolt can be provided in the anti-dropping screw hole. The anti-dropping bolt can be removed. The anti-dropping bolt can prevent the mounting sleeve 24 from sliding and falling off.

[0052] During the specific installation, first pull the latch 25 outward, the baffle 251 moves accordingly and compresses the spring 252, then the installation slot 241 in the installation sleeve 24 is inserted into the cantilever 21, and the installation slot 241 is moved to a suitable position so that the socket 210 on the cantilever 21 is aligned with the slot 242, and then the latch 25 is released, and the latch 25 is inserted into the socket 210 through the slot 242 under the elastic force of the spring 252, thereby fixing the cantilever 21 and the hanger 22 together; when the hanger 22 needs to be removed from the cantilever 21, the latch 25 can be pulled outward so that the latch 25 can be pulled out of the socket 210 of the cantilever 21, thereby making the disassembly and assembly of the hanger 22 and the cantilever 21 very convenient and fast. Among them, it is preferred to set a plurality of sockets 210 on the cantilever 21, so as to facilitate the adjustment of the installation position of the hanger 22 on the cantilever 21, so that the workpiece can be installed in a suitable position for better polishing.

[0053] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can also make many forms without departing from the scope of protection of the utility model and the claims, all of which are within the protection of the utility model.
