Description
Technical Field
The utility model relates to a processing device of a gate plate of a gate valve, which is used for turning the inclined plane of the gate plate.
Background
The gate plate structure of the gate valve is shown in fig. 3 and 4, and comprises a plate body 11, wherein a convex ring 10 transversely extends outwards from the outer edge part of one surface of the plate body, the ring surface of the convex ring is inclined with the plate body, a circular convex surface 12 is arranged at the central part of the other surface of the plate body, the gate plate is symmetrically formed by two plate bodies, the circular convex surfaces of the plate bodies are attached, 3 through holes are symmetrically drilled on the circular convex surfaces, and bolts 13 penetrate through the through holes to connect the plate bodies.
The inclined surface of the convex ring is usually machined by milling, the milling travel is longer than the diameter of the plate body, and the efficiency is not high and needs to be improved.
Disclosure of Invention
In view of the above, the present utility model provides a gate valve gate plate machining device capable of improving machining efficiency.
The technical scheme of the utility model is that the processing device of the flashboard of the gate valve comprises a disc chuck 2 connected to a lathe spindle 1, and a positioning seat 3 is fixedly connected to the disc chuck.
The use method of the processing device of the flashboard of the gate valve comprises the steps of sleeving a through hole of a plate body on a positioning column, enabling a circular convex surface 12 of the plate body to be attached to the end face of a positioning seat, enabling a movable thimble to advance to drive a pressing head to tightly press the plate body, then starting a lathe, and enabling a turning tool 9 to cut the annular surface of a convex ring.
The turning stroke is the difference between the outer circle of the convex ring and the inner circle of the convex ring, and compared with milling, the turning stroke can be greatly shortened, and the working efficiency can be improved; the plate body is convenient to assemble and disassemble, and the labor intensity can be reduced.

The attached sign: the lathe comprises a 1-lathe spindle, a 2-disc, a 3-positioning seat, a 4-positioning column, a 5-pressure head, a 6-center, a 7-movable center, an 8-taper shank, a 9-lathe tool, a 10-convex ring, an 11-plate body, a 12-circular convex surface, a 13-bolt and a 14-through hole.
Detailed Description
Specific embodiments of the present utility model will now be described with reference to the accompanying drawings.
The utility model provides a processing apparatus of flashboard of gate valve, it includes the disc chuck 2 of connecting on lathe main shaft 1, fixedly connected with positioning seat 3 on the disc chuck, the diameter of positioning seat is roughly equal with the diameter of the circular convex surface 12 of plate body, the right-hand member face of positioning seat is inclined with the perpendicular of lathe main shaft axis, its inclination alpha equals with the anchor ring of bulge loop and the angle that the plate body inclines, the reference column 4 has been inlayed perpendicularly in the right-hand member face of positioning seat, the reference column cooperatees with the through-hole 14 on the flashboard plate body 11, the quantity of reference column equals with the through-hole 14, the right side of positioning seat is equipped with pressure head 5, the left end face of pressure head is the inclined plane, this inclined plane can be parallel with the right-hand member face of positioning seat, be equipped with the centre bore on the right-hand member face of pressure head, the centre bore cooperatees with the top 6 of loose thimble 7, loose thimble 8 inserts in the tailstock of lathe (the tailstock is not drawn).
The use method of the processing device of the flashboard of the gate valve comprises the steps of sleeving a through hole of a plate body on a positioning column, enabling a circular convex surface 12 of the plate body to be attached to the end face of a positioning seat, enabling a movable thimble to advance to drive a pressure head to press the plate body, then starting a lathe, and enabling a turning tool 9 to cut the annular surface of a convex ring. Fig. 2 is a schematic view of clamping a plate body.
The right end face of the pressure head extends rightward to form a sleeve, and the sleeve is sleeved on the cylinder at the right part of the center, so that the pressure head is connected into a whole, and the pressure head is prevented from being aligned with the movable thimble or taken down when the pressure head is assembled and disassembled.
The left end face of the pressure head is provided with a concave part, so that the pressure head can be better contacted with the plate body.
The turning device has the advantages that the annular surface of the convex ring is turned, the travel of the turning tool is the difference between the outer circle of the convex ring and the inner circle of the convex ring, the travel of the turning tool is greatly shortened, and the working efficiency can be improved; the plate body is convenient to assemble and disassemble, and the labor intensity can be reduced.
