Abstract
The utility model discloses a grinding tool for a flange joint surface on a steam turbine steam cylinder steam leading pipe. The grinding tool is used for flange joint surface grinding and comprises a jack (1) with a base (6), a cardan joint (2) and a grinding disc (5). The jack (1) is connected with the grinding disc (5) through the cardan joint (2), and the cardan joint (2) is provided with an operating rod (4). According to the grinding tool, an upper steam cylinder steam leading pipe horizontal joint surface can be ground without turning over an upper steam cylinder, the grinding tool is simple and easy to use, field conduction is facilitated, time and labor are saved, and the requirement for grinding quality can be met.
Description
Technical field
The utility model relates to the mechanical lapping field, particularly a kind of steam turbine steam guiding tube upper flange faying face milling tool.
Background technology
During the steam turbine of thermal power plant overhaul, need to clear up grinding to steam turbine flange steam guiding tube flange horizontal integration face.When lower cylinder half flange and steam guiding tube lower flange are ground, because of flange face towards top, use manually and reach the electric grinding instrument all more for convenience, but when casing top half steam guiding tube flange is ground, because of flange face towards ground, use the manual electric grinding instrument that reaches all to be awkward, waste time and energy and can not guarantee Grinding Quality.A lot of power plant now take the upper cylinder half upset more, during to casing top half and the grinding of steam guiding tube flange, because of flange face, towards ground, use the manual electric grinding instrument that reaches all to be awkward, and waste time and energy and can not guarantee Grinding Quality.And, because casing top half top is irregularly shaped, need to make special stand and support; Along with the increase of unit capacity, first cylinder weight 30-50 ton that weighs, comprise the steam guiding tube Partial Height and can reach 4-6 rice at present, and difficulty, risk and the workload of turning over cylinder and making special stand increase exponentially.
The utility model content
The technical problems to be solved in the utility model is that the prior art casing top half that need to overturn just can complete the grinding to casing top half steam guiding tube horizontal flange faying face, causes and produces inconvenient deficiency.
The utility model solves the technical scheme that its technical problem adopts: a kind of steam turbine steam guiding tube upper flange faying face milling tool is provided, comprise jack, universal joint and abrasive disk with base, jack connects abrasive disk by universal joint, and universal joint is provided with action bars.
Further, abrasive disk adopts brown corundum grinding stone, ceramic grinding stone, plastic cement grinding stone or similar grinding-material.
Compared with prior art, the utility model has following beneficial effect: the casing top half that 1, do not need to overturn can complete the grinding to casing top half steam guiding tube horizontal flange faying face.2, be simple and easy to and be convenient to field conduct, time saving and energy saving and can meet the Grinding Quality requirement.
The accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
As shown in Figure 1
The utility model discloses a kind of in the situation that do not turn over cylinder, the specific purpose tool that casing top half steam guiding tube horizontal flange is ground, comprise jack 1, universal joint 2 and abrasive disk 5 with base 6, jack 1 connects abrasive disk 5 by universal joint 2, universal joint 2 is provided with action bars 4, and mill 5 adopts brown corundum grinding stone, ceramic grinding stone, plastic cement grinding stone or similar grinding-material.
The utility model is a kind of instrument that can implement upward grinding, only by operating personnel's manual operations action bars 4, increase the universal joint 2 with ball on jack 1 top, as the tie point between abrasive disk 5 and jack 1, automatically regulate abrasive disk 5 by universal joint 2 and aim at centering with cylinder steam guiding tube upper flange, can be ground.
Compared with prior art, the utility model has following beneficial effect: the casing top half that 1, do not need to overturn can complete the grinding to casing top half steam guiding tube horizontal flange faying face.2, be simple and easy to and be convenient to field conduct, time saving and energy saving and can meet the Grinding Quality requirement.
