Abstract
The invention discloses a mechanical nozzle grinding device, which is characterized by comprising a rotation motor, a grinding disc and a shell, wherein the rotation motor is vertical; a slender connecting rod is arranged in the center of the upper surface of the grinding disc along the axis; the upper end of the connecting rod is connected with a coupling at the lower end of a transmission shaft of the rotation motor; the shell is of a sleeve-shaped structure; the transmission shaft of the rotation motor and the connecting rod penetrate through the center of the shell; the middle part of the shell is provided with a shoulder structure; the external diameter of the shoulder structure is equal to the diameter of a connecting port in a valve body; and the upper end of the shell is radially provided with a handle structure. The grinding disc is driven by using the rotation motor to grind the top surface of a nozzle; and since the connecting port of a valve is overlapped with the central axis of the nozzle, the shoulder structure on the device shell is arranged in the connecting port of the valve body, and the shoulder structure of the shell is in transition fit with the connecting port of the valve body, positioning and guide effects can be achieved, and rough grinding of the top surface of the nozzle is finished in the mode.
Description
Technical field
The present invention relates to a kind of mechanical type nozzle lapping device, especially a kind of efficient is high, the slight low mechanical type nozzle lapping device of work.
Background technology
Spool props up the nozzle end face of nozzle, because valve in use, corrosive gas is on the impact of nozzle in wearing and tearing between the two and the valve body pipeline, can cause the nozzle end face trickle bowl configurations to occur, and bowl configurations can cause Leakage Gas in the 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.
Summary of the invention
Technical problem to be solved by this invention a kind of mechanical type nozzle lapping device is provided, utilize turning motor to drive abrasive disk the nozzle end face ground, efficient is high, compares manual mode intensity low.
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 to comprise: the single-revolution motor, described turning motor is vertical; One abrasive disk, described abrasive disk upper surface center is along being provided with the slender type connecting rod on its axis direction, and described connecting rod upper end is connected with turning motor power transmission shaft lower end shaft coupling; One housing, described housing is sleeve-like configuration, and described turning motor power transmission shaft and connecting rod pass from its center, and described housing middle part is provided with a convex shoulder structure, described convex shoulder structure external diameter equals connector diameter on the valve body, and footpath, described housing upper end upwards is provided with the one handle structure.
Further, described connecting rod lower end is connected with abrasive disk welding or bolt.
Further, cooperate between described housing convex shoulder structure and valve body connector and be interference fits.
The invention has the advantages that: utilize turning motor to drive abrasive disk the nozzle end face is ground, because valve connector and nozzle centre axis are overlapping, place connector on the valve body by the convex shoulder structure on the crust of the device, and cooperate between housing convex shoulder structure and valve body connector and be interference fits, thereby play the effect of a location and guiding, adopt this mode to finish the corase grind of nozzle end face.
Description of drawings
The present invention is further detailed explanation 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.
Fig. 2 is a kind of mechanical type nozzle of the present invention lapping device working state schematic representation.
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, shaft coupling 4, housing 5, power transmission shaft 6, convex shoulder structure 7, handle arrangement 8.
The valve body that matches with the present invention shown in Figure 2 comprises valve body 9, connector 10, nozzle 11.
The connecting rod 3 that the present invention is mainly vertically disposed turning motor 1 and links to each other by shaft coupling 4 with turning motor, connecting rod 3 is terminal by welding or bolt connection abrasive disk 2, abrasive disk 2 is against on nozzle 11 end faces, and outside device, housing 5 being set, turning motor 1, turning motor power transmission shaft 6, shaft coupling 4, connecting rod 3 pass from housing 5 cores.For realizing accurate location, the external diameter of the convex shoulder structure 7 that housing 5 middle parts arrange equals the diameter of connector 19 on the valve body 9, and is interference fits between the two.For making things convenient for Hou Fu to press this device, in housing 5 upper ends handle arrangement 8 is set, grab surely for the user.
During work, by the abrasive disk 2 among the present invention is stretched into from the connector 10 on the valve body 9, until till the convex shoulder structure 7 at housing middle part is embedded in the connector 10, this moment hand steered handle arrangement 8, open turning motor 1 switch, rotate thereby utilize turning motor 1 to drive abrasive disk 2, nozzle 11 end faces are ground, until finish till the corase grind.
