Description
Technical field:
The utility model relates to valve body milling apparatus field, is specifically related to a kind of gate valve body fluid in-out end flange special grinder.
Background technology:
Gate valve is an opening and closing element flashboard, and valve inner medium channel is straight-through, and medium is in line flowing, and flow resistance is little.With stop valve Comparatively speaking, no matter be out or close, ram movement direction is all perpendicular with media flow direction, therefore open and close time more laborsaving.
In the production process of gate valve body, due to the reason such as mould and die accuracy or operation, can there is hackly phenomenon in flange sealing surface and the flange outer wall of valve body fluid in-out end.Wherein the coarse injustice of flange sealing surface directly will affect the connection sealing of valve body and fluid inlet and outlet piping, easily causes the leakage of fluid; And the coarse injustice of flange outer wall not only can affect valve body outward appearance, and easily human body skin is damaged when installing and using.In order to avoid the generation of these unfavorable phenomenons, need that grinding is carried out to flange sealing surface and outer wall and make its flat smooth.And the valve body grinder used at present exist valve body fixing not firm, grinding precision is low and speed slow and the shortcoming such as fragile valve body structure.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of grinding precision high and fireballing gate valve body fluid in-out end flange special grinder.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of gate valve body fluid in-out end flange special grinder, comprise frame, be located at the fixed mechanism in frame and be located at sealing surface grinding mechanism and the outer wall grinding mechanism at fixed mechanism two ends respectively, described fixed mechanism is made up of two U-shaped fixed mounts be arranged in parallel and the L bracket being located at fixed mount side, the first cylinder is provided with above fixed mount, described first cylinder upper end is fixed on support, lower end is provided with pressing plate, described sealing surface grinding mechanism and outer wall grinding mechanism are by guide rail, be arranged on the lapping device on guide rail, the second cylinder be connected with lapping device rear end forms, described lapping device comprises gripper shoe, motor, rotating disk and grinding head, described disk axes is provided with rotating shaft, motor drives rotating shaft to rotate by chain drive, the grinding head of described sealing surface grinding mechanism is arranged on disk axes, the grinding head bias of outer wall grinding mechanism is arranged on rotating disk.
The longitudinal center line of described rotating disk and the longitudinal center line of flange are on same straight line.
The grinding head diameter of described sealing surface grinding mechanism is equal with flange outer diameter, and the grinding head of outer wall grinding mechanism and the spacing of rotating disk longitudinal center line are 1/2 times of flange outer diameter.
Described pressing plate is in square, and the length of side is greater than the external diameter of valve body and valve gap connectivity port.
Operation principle of the present utility model: be fixed on fixed mount into and out of end first by valve body to be ground before grinding, then the first cylinder band dynamic pressure plate moves downward the connectivity port making pressing plate tightly push down valve body and valve gap, thus is fixedly secured by whole valve body; Second cylinder promotion gripper shoe is moved along guide rail to the fluid inlet of valve body and the port of export subsequently, until the grinding head of sealing surface grinding mechanism is close to flange sealing surface, the grinding head of outer wall grinding mechanism is close to flange outer wall, open machine operation switch again, motor drives turntable rotation by chain drive, thus grinding head is rotated with the grinding carrying out flange sealing surface and outer wall; Grinding terminates rear motor and quits work, and the second cylinder drives grinding head to leave valve body, and the first cylinder moves upward and makes pressing plate leave valve body subsequently, is finally taken off by ground valve body.
The beneficial effects of the utility model are: structure is simple, reasonable in design, easy to operate, and can realize the grinding of fluid in-out end flange sealing surface and outer wall, grinding precision is high, speed is fast, and automaticity is high, is of value to and increases work efficiency simultaneously.
