Abstract
The invention relates to a mechanical spring grinding cutter rod for processing a sealing surface of a hydrogenation reactor. A fixed cutter rod is clamped on a manual feeding device; a left rotated spring is connected with a moveable cutter rod and the fixed cutter rod under the supporting of a spring spindle; the moveable cutter rod and the fixed cutter rod are connected through a fastening rivet for the moveable cutter rod and the fixed cutter rod; the moveable cutter rod and the fixed cutter rod can rotate by taking the fastening rivet for the moveable cutter rod and the fixed cutter rod as a shaft; the moveable cutter rod is connected with a universal chuck through a connecting rivet for a universal chuck and the moveable cutter rod and can rotate by taking the connecting rivet for the universal chuck and the moveable cutter rod as the shaft; and a slotted flat end fastening bolt is fixed on the universal chuck. The mechanical spring grinding cutter rod provided by the invention has the advantages of good grinding processing effect for mechanical sealing surface, easiness in operation and capability of reducing risk; a grinding mould can be replaced by the mechanical spring grinding cutter rod and the processing cost is saved; and the mechanical spring grinding cutter rod is suitable for being used as a grinding processing tool for the sealing surface.
Description
Technical field
What the present invention proposed is machine tools, and specifically a kind of machine of processing the hydrogenation reactor front cover grinds knife bar with spring.
Background technology
Hydrogenation reactor is a third class(grade) pressure vessel; Its sealing reliability is directly connected to the pressure vessel security of products; Along with China's rapid economy development; All kinds of press demands constantly enlarge, and high temperature resistant, high pressure resistant need for equipment and device maximize, and require the specification of equipment and production capacity constantly to enlarge to adapt to the requirement of industry development.
China's pressure vessel industries development rapidly; The research and development and the production scale of all kinds of pressure vessels constantly enlarge, and pressure vessel is to high temperature resistant, high pressure resistant and large scale development, and hydrogenation reactor must seal in process of production; Prevent the leakage of hydrogen, reactor is normally carried out.
Along with equipment volume increases, difficulty of processing continues to increase, and the grinding of the key position dovetail groove of sealing is adopted the vertical grinding of grinding tire by routine, and the people need stand in high aerial operation, and risk is very big, and not easy to operate.
Summary of the invention
In order to realize that the attrition process of hydrogenation reactor sealing surface the present invention proposes
OneThe machine of planting processing hydrogenation reactor front cover grinds knife bar with spring.This split holder is connected through spring with movable knife bar through fixing knife bar, the technical problem of solution sealing surface attrition process.
The scheme that technical solution problem of the present invention is adopted is:
Fixedly the knife bar clamping is on manual feed arrangement; Left-handed spring reaches fixedly with movable knife bar under central spindle of the spring supports, and knife bar is connected; Movable knife bar and fixedly knife bar pass through movable knife bar and be connected with the fixing fastening rivet of knife bar; Movable knife bar and fixing knife bar with movable knife bar and fixedly the fastening rivet of knife bar serve as spool can rotate; Movable knife bar is connected rivet through universal chuck and is connected with universal chuck with movable knife bar, and to be connected rivet with movable knife bar with universal chuck serve as spool can rotate, and the flush end holding screw of slotting is fixed on the universal chuck.
Good effect, the present invention is effective to the mechanical sealing surface attrition process, and is easy to operate, reduced risk.Can substitute the grinding mold, practice thrift processing cost.Suitable attrition process tool applications as sealing surface.
Description of drawings
Fig. 1 is a front view of the present invention
Fig. 2 is a vertical view of the present invention
Among the figure, 1. universal chuck, 2. fluting flush end trip bolt, 3. movable knife bar, 4. central spindle of the spring, 5. left-handed spring, 6. fixing knife bar, 7. movable knife bar and the fixing fastening rivet of knife bar, 8. universal chuck is connected rivet with movable knife bar.
The specific embodiment
According to the figure; Fixedly knife bar 6 clampings are on manual feed arrangement; Left-handed spring 5 reaches fixedly with movable knife bar 3 under central spindle of the spring 4 supports, and knife bar is connected; Movable knife bar and fixedly knife bar be connected with the fixing fastening rivet 7 of knife bar by movable knife bar, movable knife bar and fixedly knife bar with movable knife bar and fixedly the fastening rivet of knife bar serve as spool can rotate, movable knife bar passes through universal chuck and is connected rivet 8 with movable knife bar and is connected with universal chuck 1; And to be connected rivet with movable knife bar with universal chuck serve as that axle can rotate, and fluting flush end holding screw 2 is fixed on the universal chuck.
Embodiment
The present invention is applied in the actual processing of TX6216C horizontal boring machine, and the equipment entire length of hydrogenation reactor is all more than 15 meters, and the dovetail groove on the sealing surface is 23 degree; Dovetail groove central diameter ∮ 692mm uses grinding split holder clamping on manual feed arrangement, under the cutting force effect that spring applies in machine; Grinding tool contacts with machined surface fully; Be to guarantee the grinding tool uniform wear simultaneously in process of lapping, utilize manual feed arrangement reciprocating feed constantly, revolution is to a certain extent about 50r/min; Use the washing oil cooling and lubricating, accomplish the grinding of dovetail groove.Be installed in manual delivering gear on the radial tool post of facing head, adjustment cutter corner of table degree can carry out attrition process to inclined-plane, plane, hole, lining, the cylindrical of different angles.
Characteristics of the present invention:
Because left-handed spring has very strong rigidity and toughness, can cutting force be delivered on the movable knife bar, when grinding tool contacts with machined surface,, therefore can guarantee that grinding tool contacts with machined surface fully because universal chuck and movable knife bar are to be rotationally connected.
The present invention grinds knife bar and can be installed to vertical lathe or horizontal lathe and lie upward use of bed.
