Description

Technical Field

[0001] The utility model relates to the technical field of mechanical seal processing, in particular to a grinding and polishing device for mechanical seal processing. Background Art

[0002] Mechanical seals are one of the basic mechanical components with precise and complex structures. They are key components of various pumps, reaction synthesis kettles, turbine compressors, submersible motors and other equipment. Among them, graphite rings are mainly used for sealing the rotating parts of machinery.

[0003] When the existing device is grinding and polishing the graphite ring, it is necessary to stop the machine to load and unload the graphite ring. At the same time, during the grinding and polishing, individual graphite rings are generally polished one by one, resulting in low grinding and polishing efficiency of the entire device. Utility Model Content

[0004] The problem solved by the utility model is to provide a grinding and polishing device for mechanical seal processing, which solves the technical problems that when the existing device grinds and polishes the graphite ring, it is necessary to stop the machine to load and unload the graphite ring. At the same time, when grinding and polishing, single graphite rings are generally polished one by one, resulting in low grinding and polishing efficiency of the entire device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A grinding and polishing device for processing mechanical seals includes a base, a base column and a grinding roller. Several base columns are installed around the bottom side of the base, and a grinding roller is installed at the center of the top side of the base. Several mounting grooves and slide grooves are opened at equal angles on the base. A pneumatic cylinder is installed in the mounting groove. The telescopic end of the pneumatic cylinder is located in the slide groove and a slide is installed. A screw is installed on the bearing of the slide. Multiple graphite rings are stacked on the screw, and a nut is threadedly installed on the screw.

[0007] Preferably, a reducer is installed on the bottom side of the base, the output end of the reducer is connected to the grinding roller, and the input end of the reducer is connected to the output end of the first motor.

[0008] Preferably, the inner wall of the slide groove is provided with a slide rail, and the slide seat moves along the slide rail.

[0009] Preferably, a second motor is installed at the bottom of the slide seat, and an output end of the second motor is connected to the screw.

[0010] Preferably, a conical aggregate cover is installed on the bottom side of the base and outside the reducer, and an aggregate frame is installed below the conical aggregate cover.

[0011] The beneficial effects of the utility model are as follows: a plurality of grinding stations which do not interfere with each other are arranged on the base, and the adjustment of the grinding stations is achieved through the translation of the slide seat. At the same time, the screw on each grinding station can be installed with multiple graphite rings, so that the multiple graphite rings can be polished synchronously. At the same time, the multiple grinding stations can be used to realize non-stop loading and unloading, which greatly improves the grinding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Specific examples are given below.

[0019] See also Figures 1 to 3A grinding and polishing device for mechanical seal processing includes a base 1, a base column 2 and a grinding roller 5. Several base columns 2 are installed around the bottom side of the base 1, and a grinding roller 5 is installed at the center of the top side of the base 1. A reducer 3 is installed on the bottom side of the base 1. The output end of the reducer 3 is connected to the grinding roller 5, and the input end of the reducer 3 is connected to the output end of the first motor 4. When the first motor 4 works, the reducer 3 is driven to drive the grinding roller 5 to rotate, which is convenient for grinding the graphite ring contacting the grinding roller 5. Several mounting grooves 6 and slide grooves 7 are opened at equal angles on the base 1. A pneumatic cylinder 8 is installed in the mounting groove 6. The pneumatic cylinder The telescopic end 8 is located in the slide 7 and a slide 9 is installed. The inner wall of the slide 7 is provided with a slide rail. The slide 9 moves along the slide rail. A screw 10 is installed on the bearing of the slide 9. A plurality of graphite rings are stacked on the screw 10, and a nut 11 is threadedly installed on the screw 10. The slide 9 is driven by the pneumatic cylinder 8 to move along the slide rail in the slide 7. When the slide 9 is away from the grinding roller 5, the graphite rings on the screw 10 are loaded and unloaded. The nut 11 is loosened to facilitate the removal of the polished graphite ring from the screw 10. At the same time, the unpolished graphite rings are stacked and placed on the screw 10, and the nut 11 is tightened to fix them.

[0020] A second motor 12 is installed at the bottom of the slide 9. The output end of the second motor 12 is connected to the screw 10. The second motor 12 drives the screw 10 and the graphite ring to rotate, thereby achieving 360° comprehensive grinding and polishing of the graphite ring.

[0021] A conical aggregate cover 13 is installed on the bottom side of the base 1 and outside the reducer 3, and an aggregate frame 14 is installed below the conical aggregate cover 13. The waste chips generated by grinding fall onto the conical aggregate cover 13 through the chute 7 and are collected into the aggregate frame 14 along the inclined surface of the conical aggregate cover 13 under the action of gravity.

[0022] The pneumatic cylinder 8 drives the slide 9 to move along the slide rail in the slide groove 7. When the slide 9 is away from the grinding roller 5, the graphite ring on the screw 10 is loaded and unloaded, and the nut 11 is loosened to facilitate the removal of the polished graphite ring from the screw 10. At the same time, the unpolished graphite rings are stacked and placed on the screw 10, and the nut 11 is tightened to fix them. Then the slide 9 moves until the graphite ring contacts the grinding roller 5. At this time, the first motor 4 is operated and the reducer 3 is driven to drive the grinding roller 5 to rotate, and then the outer wall of the graphite ring is polished. At the same time, the second motor 12 is operated to drive the screw 10 and the graphite ring to rotate, thereby achieving 360° comprehensive polishing of the graphite ring.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
