Abstract
The utility model relates to a polishing device for steel-made ring sealing grooves, which comprises a casing with a hollow cavity. A preloaded spring is arranged in the hollow cavity of the casing; the spring is arranged between a positioning block and a tip wire at the tail; a grinding head is arranged at the head of the positioning block; the grinding head is outside the casing; the positioning block and the cavity have clearance. The grinding head and the positioning block float up and down and position by the elastic force of the spring; thereby adjusting the tightness of the tip wire at the tail can change the grinding and polishing pressure. The grinding head is made by ductile iron and generally engraved with three to four zigzag grooves; the direction of the grooves is perpendicular to the rotation direction of the polishing device; the grooves are coated with lapping paste. The utility model is fixed on vertical lathe tool holder to use; the operation is simple and can be mastered by ordinary skilled workers; the utility model has high processing efficiency and strong practicability, and overcomes the disadvantages of low flatness and obvious oscillation mark caused by traditional polishing method. The utility model has low fabrication cost, and provides a practical processing method for nationalized manufacturing steel-made large imported equipments and fabricating large precision dies.
Description
Technical field
The utility model is used for machine-building, mould manufacturing field, as the processing of steam power plant's regulator cubicle seal groove, the processing of import large-size chemical container seal groove, the processing of large mold seal groove etc.
Background technology
The polishing processing of conventional steel seal of vessel groove, mould seal groove, be finished to the master with sand paper, oilstone, pertinent literature also more recommends these two kinds of methods, but the quality problems (flatness is poor, oscillation mark is obvious) that they produced in the processing of " large sealing groove " are fatal.In import equipment is made, often to process by senior technician, waste product is also unavoidable, and the duration delays again and again especially, and manufacturing cost is too high.The common laborer is forbidding especially to this task.
The cylinder iron excellent technology of grinding, polishing, existing machinery processing handbook is all carried seldom, so most practitioner is difficult to grasp this technology.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple to operate, and the general technology workman all can operate, the burnishing device of working (machining) efficiency height, steel annular seal groove that crudy is good.
The burnishing device of steel annular seal groove of the present utility model is characterized in that comprising the housing of being with cavity, in the cavity of housing preloading spring is set, spring places between locating piece and the afterbody jackscrew, the head of locating piece is a grinding head, and grinding head is outside housing, and locating piece and cavity have the gap.
Grinding head of the present utility model and locating piece are adjusted the elasticity of afterbody jackscrew by means of the elastic force of the spring location of fluctuating, and can change the size of grinding, polish pressure.The middle part preloading spring can make grinding head that cannelure is had enough big polish pressure all the time, is set in respectively after both ends of the spring polishes in locating piece and the afterbody jackscrew, and polarization is better.
Described locating piece can be T-shape, and is terminal for butt end connects spring, with the gap of cavity be 0.15～0.3mm, the gap of front end and cavity outlet formation is 0.15～0.3mm.Form strict perpendicular positioning between grinding head and the workpiece, eliminated horizontal hunting to greatest extent, so the whole workpiece flatness is higher after grinding.
Grinding head adopts the spheroidal graphite cast-iron manufacturing, and abradant surface is done polishing, is carved with the zigzag groove on it, general 3～4 roads, groove direction is vertical with the burnishing device direction of rotation, holds abrasive pastes in the groove, grinding effect is further improved, further reduce the roughness of annular seal groove.
The degree of depth of the aspect ratio seal groove of grinding head exceeds 3～5mm, and width is advisable than the little 0.4～0.6mm of width of seal groove.
The utility model is fixed on the vertical lathe knife rest and uses, and utilizes spheroidal graphite cast-iron that performance lubricated, vibration damping is arranged, and adjusts vertical lathe rotational line speed to the 0.5m/s, can avoid cannelure to produce the flatness that oscillation mark can improve cannelure again.
Advantage of the present utility model:
Simple to operate, can be grasped by the general technology workman, the working (machining) efficiency height, practical, improved low, the oscillation mark significant disadvantages of flatness that traditional polishing method is brought greatly.Low cost of manufacture is for the manufacturing of steel imported large-scale home-made equipment, the manufacturing of large-scale precision mould provide practicable manufacturing process.Be fit to the processing diameter greater than 800mm, the steel annular seal groove of groove width 8～20mm, polishing back plane Du Keda 0.15, roughness reaches 0.8.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 groove, 2 grinding heads, 3 locating pieces, 4 housings, 5 preloading springs, 6 afterbody jackscrews
The specific embodiment
In conjunction with Fig. 1 the utility model is described.
Housing 4 is a cylindrical structure, mills to be fixed on the vertical lathe knife rest after flat.Preloading spring 5 is set in the cavity of housing 4, after polishing, both ends of the spring is set in the locating piece 3 that is positioned at its two ends and 5 millimeters grooves of afterbody jackscrew 6, locating piece 3 is T-shape, the gap of butt end and cavity (A place) is 0.15～0.3mm, and the outlet of front end and cavity (B place) forms the gap of 0.15～0.3mm.Grinding head 2 is square, uses the spheroidal graphite cast-iron manufacturing, is carved with 3～4 road grooves 1 on the abradant surface, and direction is vertical with lathe main body direction of rotation (direction of rotation of burnishing device), is coated with abrasive pastes in the groove.The degree of depth of the aspect ratio seal groove of grinding head exceeds 3～5mm, and width is than the little 0.4～0.6mm of sealing groove width.
Grinding head is placed in the seal groove that will polish, start lathe operation and get final product, vertical lathe rotational line speed is preferably in about 0.5m/s, and polish pressure is determined by the elasticity of adjusting the afterbody jackscrew.
