Abstract
The invention discloses a mechanical nozzle grinding device. The mechanical nozzle grinding device is characterized in that the mechanical nozzle grinding device is mainly provided with a rotary dynamo arranged vertically and a grinding plate which is connected with a rotary dynamo drive shaft through a connecting rod, the grinding plate is welded or bolted at the lower end of the connecting rod, the rotary dynamo is arranged in a shell, a replaceable pilot sleeve is arranged on the lower position of the shell, a shell bolt is connected with the top surface of the pilot sleeve, a protruding shoulder structure is arranged on the upper end portion of the pilot sleeve, the protruding shoulder structure is embedded on a valve body connecting mouth, and the shell can be bolted with a plurality of pilot sleeves with the same diameters with the valve body connecting mouth. By bolting the shell and the pilot sleeves with required standards, the pilot sleeves are used for abutting against the valve body connecting mouth, the mechanical nozzle grinding device plays a role in guiding orientation, and brings convenience to subsequent using the grinding plate driven by the rotary dynamo to grind a nozzle top surface, and a concave pit structure of the nozzle top surface is removed. Proper pilot sleeves are only needed to be chosen to be bolted with the shell according to the valve bodies with different standards, and therefore carrying volume is reduced.
Description
Technical field
The present invention relates to a kind of mechanical type nozzle lapping device, especially a kind of mechanical type nozzle lapping device that is suitable for different valve body connector bores.
Background technology
Spool props up the nozzle end face of nozzle, due to valve in use, the impact of corrosive gas on nozzle in wearing and tearing between the two and valve body pipeline, can cause the nozzle end face trickle bowl configurations to occur, and bowl configurations can cause Leakage Gas in valve body, traditional method is by the mode of abrasive disk hand-ground, the nozzle end face to be ground for this reason, thereby remove the bowl configurations on the nozzle end face, be convenient to and the spool assembling, but adopt manual mode labour intensity high, efficient is not high yet.Reduce labor intensity for raising the efficiency, now propose a kind of mechanical polishing device, but due to the different problem of different valve body connector diameter, thereby need to carry for the valve of different bores different lapping devices, therefore carry inconvenience.
Summary of the invention
Technical problem to be solved by this invention a kind of mechanical type nozzle lapping device is provided, utilizing turning motor to drive abrasive disk grinds the nozzle end face, the pilot sleeve consistent with the connector bore that employing can substitute is connected with housing, thereby during the valve of maintenance different size, only need additionally carry the pilot sleeve of some different sizes and the abrasive disk of a little and get final product.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of mechanical type nozzle lapping device, and its innovative point is; The abrasive disk that described mechanical type nozzle lapping device is mainly vertically disposed turning motor and is connected with the turning motor power transmission shaft by connecting rod, described abrasive disk and connecting rod lower end welding or bolt; Described turning motor is placed in housing, and described housing below is provided with a pilot sleeve that can substitute, and the pilot sleeve end face is connected with the housing bolt, and described pilot sleeve upper end is provided with convex shoulder structure, and described convex shoulder structure is embedded in the valve body connector; But some pilot sleeves of described housing bolt and valve body connector equal diameters.
Further, described housing end face is provided with end socket, and described end socket is connected with the housing bolt.
Further, described housing upper side is provided with operating grip, and described operating grip and housing are integrated cast structure.
The invention has the advantages that: by the pilot sleeve bolt with housing and required specification, utilize pilot sleeve to prop up the valve body connector, play the effect of a good guide-localization, thereby be convenient to the follow-up abrasive disk that utilizes turning motor to drive, the nozzle end face is ground, remove the bowl configurations of nozzle end face.For the valve body of different size, only need to select suitable pilot sleeve and housing bolt, reduced the amount of carrying.
Housing end face bolt connects end socket, thereby prevents that dust from entering enclosure interior, and is convenient to the installation of turning motor etc.In addition at operating grip of housing upper side one casting, thereby be convenient to the actual use of user.
Description of drawings
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of a kind of mechanical type nozzle of the present invention lapping device.
Structural representation when Fig. 2 is a kind of mechanical type nozzle of the present invention lapping device duty.
The specific embodiment
A kind of mechanical type nozzle lapping device shown in Figure 1 comprises turning motor 1, abrasive disk 2, connecting rod 3, housing 4, power transmission shaft 5, pilot sleeve 6, convex shoulder structure 7, end socket 11, operating grip 12.
Valve body during duty of the present invention shown in Figure 2 comprises valve body 8, connector 9, nozzle 10.
The abrasive disk 2 that mechanical type nozzle lapping device of the present invention is mainly vertically disposed turning motor 1 and is connected with turning motor power transmission shaft 5 by connecting rod 2,3 ends welding or bolts under abrasive disk 2 and connecting rod.Turning motor 1 is placed in housing 4, housing 4 belows are provided with a pilot sleeve that can substitute 6, pilot sleeve 6 end faces are connected with housing 4 bolts, pilot sleeve 6 upper ends are provided with convex shoulder structure 7, convex shoulder structure 7 is embedded in valve body connector 9, but some pilot sleeves 6 of housing 4 bolts and valve body 8 connector equal diameters.
Housing 4 end faces are provided with 11 of envelopes, and this end socket is connected with the housing bolt, thereby are convenient to the installation of turning motor etc., and play and prevent that dust from entering the purpose of enclosure interior.Another housing upper side is provided with operating grip 12, and operating grip and housing be integrated cast structure, thereby is convenient to the actual use of user.
During specific works, difference according to valve body connector 9 bores, select bore is identical with it pilot sleeve 6 and housing 4 bolts, then the abrasive disk 2 that assembles is stretched in valve body connector 9, make it to contact with nozzle 10, utilize pilot sleeve 6 to be embedded in guide-localization effect in valve body connector 9, then open turning motor 1, drive abrasive disk 2 and rotate nozzle 10 end faces are ground.
