Description
The utility model relates to a kind of milling apparatus of valve annular sealing plane.
Existing valve-seating equipment divides two big classes, one class is that abrasive disk is that cast iron plate need add the grinding agent by lapping liquid and abrasive material preparation when grinding, in the process of lapping, to the outer edge slippage and the accumulation of ring surface, sealing surface outer edge stock removal is many easily for grinding agent and abrasive grit, collapse in easily causing and collapse outward, intermediate projections, grinding precision are not high, and abrasive disk needs often to repair to adjust, and the special plane special use is difficult to the valve body that is installed on the pipeline is carried out field maintenance.Another kind of is that abrasive disk is the oilstone dish, Chinese patent (patent No. is 88213704) discloses a kind of valve grinding machine, this machine has overcome the shortcoming of above-mentioned various type equipment, adopt oilstone fine abrasive technology, only need add lapping liquid in the process of lapping, the grinding precision height, surface roughness can reach 02, radially the goodness of fit can reach 80%, is a kind of comparatively desirable milling apparatus.But its power source part (comprising motor, decelerator) connects into one with the feed shaft cover that is shaped on outer tooth bar, moves up and down with length feed.If improve the functional reliability of grinder and increase speed reducing ratio, need to increase decelerator size and weight, and the increase of weight will cause vibration to a certain degree, causes precise decreasing.So, be guaranteeing machining accuracy, the functional reliability of decelerator is subjected to certain influence, and to the grinding head of horizontal arrangement mill, need carry out one-level and slow down, and this makes the grinding head structure complicated.Simultaneously, for realizing grinding and the field repair to various flaps, stop valve and gate valve body, adopt the combining form of different units, this makes manufacturing cost higher.
The purpose of this utility model provides a kind of novel high accuracy, highly versatile, reliable operation, the valve-seating equipment of low cost of manufacture.
The utility model adopts oilstone fine abrasive technology equally.Structure comprises power source part, transmission mechanism, grinding head, longitudinal feed mechanism and housing assembly.The power source partial fixing can not relatively move with housing assembly on housing assembly, the input of power source part output shaft and transmission mechanism, and promptly driving shaft (27) connects, the output of transmission mechanism,
Be that driven axle sleeve (8) is connected with grinding head power shaft (21), driving shaft (27) is connected for flexible fit with driven axle sleeve (8).The rack gear of longitudinal feed mechanism for forming by gear shaft (51), the moving sleeve (9) that is shaped on outer tooth bar and controls (33) etc., and be supporting member with positioning disk (24).The driven axle sleeve (8) of transmission mechanism is positioned at moving sleeve (9), and the two becomes rotary pair to connect, and the grinding head shell is fixedlyed connected with moving sleeve (9) lower end.
When power source partly rotates, drive grinding head power shaft (21) and rotate by the driving shaft (27) of transmission mechanism, driven axle sleeve (8), thereby make mill (18) eccentric rotary of grinding head, the compound motion of mill (18) rotation and revolution has formed desirable grinding track.
When the controls (33) that rotates longitudinal feed mechanism with hand, gear shaft (51) rotates, because tooth bar transmission, moving sleeve (9) is moved up or down, driven axle sleeve (8) that is connected with moving sleeve (9) one-tenth rotary pair and the grinding head shell of fixedlying connected with moving sleeve (9) lower end also move up or down simultaneously, because driven axle sleeve (8) is that flexible fit is connected with driving shaft (27), can relatively move up and down again so driven axle sleeve (8) can transmit the rotation of driving shaft (27).Thereby realized the length feed motion.
Grinder described in the utility model is installed on the workbench, just can grind the sealing surface of seat of stop valve, flap and gate valve flap sealing surface etc., this grinder is installed on the stop valve flange (can realizes), just can carry out field maintenance the seat of stop valve sealing surface by a transition terminal pad.The utility model since with the power source partial fixing on housing assembly, its design size and weight are not subjected to strict restriction, and configurable speed changer, divide rotating speed output not at the same level, to adapt to the requirement of different rotating speeds, transmission is quite steady, be difficult for producing vibration, the grinding precision height, and work is quite reliable, long service life.Driving shaft (27) adopts flexible fit to be connected with driven axle sleeve (8), makes length feed flexibly, reliably.A loom can be realized the sealing surface of valve seats such as various flaps and stop valve is ground highly versatile.The utility model compact conformation, low cost of manufacture is applicable to reparation and the field maintenance to valve of valve factory manufacturing valve and valve applying unit.
For the utility model can be ground the gate valve sealing surface of seat, further improve its versatility, the angle adjusting mechanism that is provided with the transverse feed mechanism that can make positioning disk (24) move left and right and positioning disk (24) is rotated reaches the locking device that has prevention moving sleeve (9) to move on positioning disk (24); And the driving shaft of transmission mechanism (27) is to form by Hooks coupling universal coupling (6), jackshaft (5) and Hooks coupling universal coupling (4) successively to be connected with being connected of power source part output shaft, and promptly upper and lower two ends of jackshaft (5) are connected with power source part output shaft by Hooks coupling universal coupling (4 and 6) respectively and are connected with driving shaft (27) upper end.Angle adjusting mechanism can be realized like this; Positioning disk (24) becomes the version of rotary disk to be connected with the movable stand (16) of energy traverse feed, movable stand (16) is shaped on annular T-shape groove, and one group of T-shape bolt (30) and locking nut (31) link together positioning disk (24) and movable stand (16) relative fixed.Unclamp locking nut (31), positioning disk (24) frame (16) that can relatively move rotates, because the effect of Hooks coupling universal coupling (4 and 6), positioning disk (24) rotates to be regulated flexibly, make the mill (18) of grinding head be adjusted to certain angle position, tighten locking nut (31) then, positioning disk (24) just is fixed on the movable stand (16).
Transverse feed mechanism can adopt screw mandrel transmission or tooth bar transmission, by optical axis positioning and guiding or dovetail groove positioning and guiding etc., makes movable stand (16) move left and right of supporting positioning disk (24).When adopting screw mandrel transmission luminous intensity distribution axle positioning guiding structure, concrete structure is: nut (29) kink is on movable stand (16), form the worm drive pair with the screw mandrel (11) that housing assembly becomes rotary pair to be connected with nut (29), the end that screw mandrel (11) exposes the housing assembly outside is fixed with handwheel (13); Movable stand (16) is shaped on two open-works, disposes optical axis (10 and 15) in two open-works respectively, and optical axis (10 and 15) is individually fixed on the housing assembly, and like this, movable stand (16) can be gone up move left and right at optical axis (10 and 15).
