Abstract
The utility model discloses a screw thread flange sealing surface's grinding frock, include: handle, grinding body, connecting rod, handle and connecting rod upper end fixed connection, it is the lower little big inverted circular truncated cone form of to grind the body to be provided with the internal thread of perpendicular to up end on the last end face centre position of grinding the body, the connecting rod lower extreme is provided with the external screw thread, the external screw thread meshes with the internal thread that grinds on the body, and the side of grinding the body is the abrasive surface that is used for grinding screw thread flange sealing surface, the inclination of abrasive surface guarantees that the abrasive surface can grind screw thread flange sealing surface, the hardness number that grinds the body is higher than the hardness number of screwed flange. Use this utility model screw thread flange sealing surface's grinding frock can reduce the milling time, the screw thread flange sealing surface's after guaranteeing again to grind sealed quality.
Description
Technical field
The utility model relates to the grinding tool of screwed flange sealing surface.
Background technology
Screwed flange is sealing device conventional on a kind of high-tension apparatus, but while often use when the idleness of equipment, the sealing surface of screwed flange just there will be corrosion pit, can affect sealing effectiveness, now we need to carry out milled processed to sealing surface, when corrosion pit is cheated when superficial, grind and can handle well easily by traditional facing-up mode, but when corrosion pit is cheated when deep, use not only length consuming time of traditional facing-up mode, and the airtight quality of screwed flange sealing surface after grinding can not be guaranteed.
Utility model content
The purpose of this utility model is: provide one can reduce milling time, can ensure again the grinding tool of the screwed flange sealing surface of the airtight quality of the screwed flange sealing surface after grinding.
For achieving the above object, the technical scheme that the utility model adopts is: the grinding tool of screwed flange sealing surface, comprise: handle, grind body, connecting rod, described handle is fixedly connected with connecting rod upper end, described grinding body is lower little large reversed round bench shaped, and be provided with the internal thread perpendicular to upper surface on the center, upper surface of grinding body, described connecting rod lower end is provided with external screw thread, described external screw thread engages with the internal thread grinding on body, the side of grinding body is the abradant surface for grinding screwed flange sealing surface, the angle of inclination of described abradant surface ensures that abradant surface can grind screwed flange sealing surface, the hardness number of described grinding body is higher than the hardness number of screwed flange.
Further, the grinding tool of aforesaid screwed flange sealing surface, wherein, is provided with the cylinder that exceeds upper surface on the center of grinding body upper surface, and the described internal thread perpendicular to upper surface is arranged on this cylinder. The weight that uses this structure can reduce to grind body, the while can ensure again the reach of internal thread, makes internal thread and external screw thread have sufficient connecting length.
Further, the grinding tool of aforesaid screwed flange sealing surface, wherein, the externally threaded reach of described connecting rod is not less than the reach of internal thread. This structure is for external screw thread and internal thread can fully be engaged, and prevents from engaging insufficient and causes loosening.
Further, the grinding tool of aforesaid screwed flange sealing surface, wherein, described handle is connected with connecting rod is vertical. Use this structure be for ensure handle with grind body upper surface parallel, make operating personnel in process of lapping easily the balance by joystick come balance grind body, reach better grinding effect.
The beneficial effects of the utility model are: use the grinding tool of screwed flange sealing surface can reduce milling time, can ensure again the airtight quality of the screwed flange sealing surface after grinding.
Brief description of the drawings
Fig. 1 is the upward view of the grinding tool of screwed flange sealing surface described in the utility model.
Fig. 2 is the cutaway view of the grinding tool of screwed flange sealing surface described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, technical scheme described in the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, the grinding tool of screwed flange sealing surface described in the utility model comprises: handle 1, grind body 2, connecting rod 3, described handle 1 is connected with the upper end of connecting rod 3, and ensure that connecting rod 3 is perpendicular to handle 1, described connecting rod 3 lower ends are provided with external screw thread 31, described grinding body 2 is lower little large reversed round bench shapeds, and be provided with the cylinder 22 that exceeds upper surface on the center of upper surface 21 of grinding body 2, and on this cylinder 22, be provided with the internal thread 221 perpendicular to upper surface 21, described internal thread 221 engages with the external screw thread 31 of connecting rod 3 lower ends, for the external screw thread 31 that makes connecting rod 3 lower ends can fully engage with the internal thread 221 grinding on body 2, prevent from engaging insufficient and cause loosening, we process to such an extent that be longer than the reach of internal thread 221 by the reach of external screw thread 31, the side of grinding body 2 is the abradant surfaces 23 for grinding screwed flange sealing surface, the angle of inclination of described abradant surface 23 ensures that abradant surface 23 can grind screwed flange sealing surface, grind the hardness number of body 2 higher than the hardness number of screwed flange.
In practical operation, handle 1 and connecting rod 3 are welded to connect, the sub-assembly again handle 1 being formed by connecting with connecting rod 3 engages with the internal thread 221 grinding on body 2 by the external screw thread 31 on connecting rod 3, make it and grind body 2 and be connected, because handle 1 vertical connecting 3, grind body 2 and be connected with connecting rod 3 by internal thread 221, also vertical with connecting rod 3, so handle 1 and grinding body 2 are in parallel position. After operating personnel install grinding tool, on the screwed flange sealing surface that has corrosion pit, coat abrasive pastes, the lower surface of the grinding tool of screwed flange sealing surface described in the utility model 24 is placed on to the gas thread place of screwed flange, abradant surface 23 is resisted against on sealing surface, then operating personnel hold handle 1 and rotate, and the sealing surface that now abradant surface 23 starts double thread flange grinds. Just can make abradant surface 23 produce downward pressure to sealing surface because grind the own wt of body 2, like this, operating personnel only need use less power just can complete grinding, in the time that operating personnel use less power turning handle 1, grinding tool is more easily operated by operating personnel, so just can ensure the stability of grinding tool in process of lapping, improve grinding efficiency, ensure again to grind the grinding effect of body 2 to sealing surface simultaneously.
Use the advantage of the grinding tool of screwed flange sealing surface described in the utility model to be: can reduce milling time, can ensure again the airtight quality of the screwed flange sealing surface after grinding.
