Description
Technical field
The utility model relates to frock, fixture manufacturing technology field, is specifically related to a kind of flat gate valve valve body sealing surface grinding tool.
Background technology
The product reliability of flat gate valve depends on the crudy of several obturators to a great extent, valve body is as the body element of gate valve, the crudy that its valve seat is installed sealing surface directly has influence on the sealing property of whole gate valve, so requires high to its required precision especially roughness and flatness.But, due to the particularity of valve body material and structure, common mechanical process technique can't meet the requirements of surface state at all at present.Valve body material mostly is steel alloy and stainless steel forgings, and after Overheating Treatment, especially the stainless steel forgings processing characteristics is poor, easily causes machined surface quality poor; The runner hole is generally deep and long hole, and the rigidity of cutter is had relatively high expectations, and the surface quality of machined surface is difficult for guaranteeing; For symmetry and the depth of parallelism that guarantees two sealing surfaces, during fine finishining, two faces must complete by clamped one time, and because two faces are opposite face, anti-lathe tool crudy is difficult to especially control in the sightless situation of process; Therefore, by single turning difficult processing to meet specification requirement.
The shortcoming of prior art is: the flat gate valve valve seal does not reach its required precision in the face of require high, traditional turning processing and the mechanical technology of roughness and flatness.
The utility model content
The purpose of this utility model is to provide a kind of flat gate valve valve body sealing surface grinding tool, can make flat gate valve valve body sealing surface attrition process convenient, and crudy is reliable.
For achieving the above object, the technical solution of the utility model is as follows: a kind of flat gate valve valve body sealing surface grinding tool, comprise mandrel, be disposed with from front to back abrasive disk, spring holder and spring on described mandrel, described abrasive disk is socketed in the mandrel front portion, and can on mandrel, move front and back, described spring holder and spring be outer being enclosed within on mandrel all, this spring one end is connected with mandrel, the other end is against the spring holder rear end, described spring holder front portion is hemispherical, and this spring holder front portion is stretched in the hemispherical groove of offering the abrasive disk rear end.
Adopt said structure, core back-end is connected with machine tool chief axis, generally to be connected with drilling machine, first abrasive disk is placed on the sealing surface that will grind, then the abrasive disk center being stretched into in the mandrel front portion is socketed with it, abrasive disk moves in a circle in the valve seat orifice of valve body, and the relative motion by the abrasive particle between abrasive disk and workpiece and grinding agent realizes the grinding to sealing plane; Spring holder and abrasive disk contact-making surface are sphere, two spheres can allow abrasive disk that certain floating space is arranged in valve seat orifice under suitable spring pressure effect, can regulate by the adaptability of sphere, make the laminating of abrasive disk maintenance and sealing plane, and avoided due to the excessive situation of damaging valve seat orifice of abrasive disk space, thereby realize that whole Grinding Quality is consistent; Pressure between abrasive disk and workpiece is realized by spring, by the advance and retreat of operation machine tool chief axis, controls the decrement of mandrel to spring, thereby controls abrasive disk and the interplanar pressure of valve seal.
Described mandrel is comprised of driving shaft and adapting rod, described driving shaft front end is fixedly connected with the adapting rod rear end, this driving shaft rear end is taper shank, described abrasive disk is socketed on the front portion of adapting rod, described adapting rod rear portion is installed with adjustment disk, described spring one end is connected on spring holder, and the other end is connected on adjustment disk.
The taper shank of driving shaft rear end is convenient to be connected with machine tool chief axis, between driving shaft and adapting rod, can be convenient to processing and install for being threaded, and the mode that adjustment disk also can be threaded connection is socketed with adapting rod.
Described abrasive disk center offers square through hole, and described adapting rod is anterior is the square column structure adapted with square through hole, and this adapting rod front end passes described square through hole.
Adopt said structure, can make abrasive disk synchronize and rotate with mandrel on the one hand, while being convenient on the other hand the machine tool chief axis advance and retreat, adapting rod is advanced and retreat and is caused that amount of spring compression changes to realize the control to abrasive disk pressure in abrasive disk.
Described spring holder rear end and adjustment disk front end all offer the spring fitting groove, and the two ends of this spring are positioned at the spring fitting groove.
Offer the discharge opening that runs through the abrasive disk front/rear end on described abrasive disk, this discharge opening front end is little, and rear end is large, is convenient to material stock and discharging.
Be provided with grinding agent splendid attire shallow slot on the front end face of described abrasive disk.
Grinding agent splendid attire shallow slot can hold grinding agent while grinding, and when grinding agent is rare, grinding agent energy automatic powder adding is added on abradant surface, thereby has improved grinding efficiency.
The beneficial effects of the utility model are: Fixture Design is reasonable, simple in structure, easy to operate, and crudy is reliable, efficiency is high, for the valve body of different size, only need, according to the size of sealing surface processing grinding dish again, frock not needed to do other any changes.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side schematic view of the present utility model;
Fig. 3 is arranged on the schematic diagram in valve body while being of the present utility model the use.
