Description
Technical field
The utility model relates to a kind of grinder, particularly a kind of DN150 that is mainly used in---the valve grinding machine that the reparation of mouth sealing surface is ground at the bottom of the valve of 300mm.
Background technology
Valve face in use often weares and teares, and influences its sealing.For the working face of experience wear, can make it become smooth by grinding, thereby reach the purpose of its sealing of reduction.So, usually grind method as valve repair.At the beginning, grinding work relies on manual carrying out, and it is consuming time not only to take a lot of work, and poor effect.In order to replace hand lapping, invented grinder, make operating efficiency improve greatly.
But existing grinder has following shortcoming, requires further improvement:
Existing grinder generally is made up of deck, power set, positioner, transmission device, mill, need assemble these parts at the scene, and inevitably, assembling is loaded down with trivial details during use.On positioner, existing grinder adopts dog screw, and after grinding a period of time, the gap will appear in mouth at the bottom of abrasive disk and the valve, need unclamp dog screw and feed on a small quantity, then locking again.Finish once grind need sometimes repeatedly to unclamp, the locking positioning screw, work efficiency is lower.
In addition, existing grinder connects mill and power transmission shaft with connector, needs when changing mill complete machine is taken off from valve body, need repeat centering when reinstalling.Have grinder now and adopt emery wheel as abrasive disk, the not only on-the-spot centering difficulty of using, and phenomenons such as sideslip, criminal block, beat are arranged when grinding, grinding precision is poor.
The content of utility model
The purpose of this utility model provides a kind of new valve grinding machine.This grinder can be realized once accurately locating, and realizes the automatic capturing and the automatic grinding of mouth at the bottom of mill and the valve, need not frequently unclamp, the locking positioning screw.
Main technical schemes of the present utility model is: a kind of valve grinding machine, comprise deck, mill and power drill, horizontal mobile device, longitudinal moving device, hue angle screw rod, location gusset, the two ends of described hue angle screw rod flexibly connect with described horizontal mobile device, described longitudinal moving device respectively, described location gusset flexibly connects with described horizontal mobile device, described longitudinal moving device respectively, have mouth on the described mill, mouth is embedded with the strong bar magnet of rare earth, and the back side of described mill is connected with a universal connecting components;
The utility model also adopts following attached technical scheme: described horizontal mobile device comprises horizontal dovetail slide rail, feed screw nut, horizontal mobile leading screw, horizontal dovetail slide 3, fixedly connected with described deck in the bottom surface of described horizontal dovetail slide rail, the middle part of described horizontal dovetail slide rail has groove, described horizontal mobile screw mandrel is positioned at described groove, and be fixed in the groove of horizontal dovetail slide rail with horizontal mobile leading screw fixed cover screw thread, on the described horizontal mobile leading screw described feed screw nut is housed, described feed screw nut is fixedlyed connected with described horizontal dovetail slide:
Described longitudinal moving device comprises and vertically moves leading screw, vertical dovetail slide rail, feed screw nut, vertical dovetail slide, the middle part of described vertical dovetail slide rail has groove, the described leading screw that vertically moves is positioned at described groove, and be fixed in the groove of described vertical dovetail slide rail with vertically moving leading screw fixed cover screw thread, described vertically moving is equipped with described feed screw nut on the leading screw, described feed screw nut is fixedlyed connected with described vertical dovetail slide;
Described longitudinal moving device is fixedlyed connected with last chain cover, and the described chain cover of going up is connected with following chain cover by support bar, and described support bar is a hollow structure, and driving chain passes from hollow space; Link to each other with described universal connecting components between chain cover and the described mill under the described transmission;
The surface adhesion self-adhesion sand paper of described mill.
The horizontal dovetail slide of the utility model utilization is realized laterally feeding, and utilizes vertical dovetail slide to realize vertically feeding, and makes the mechanical precision of portable grinder meet the machine tool accuracy requirement, and this is that existing grinder is beyond one's reach; Rely on universal connecting components and magnetic attraction to realize automatic adsorbed close with mouth at the bottom of the valve, make and grind not sideslip, do not beat, and can realize automatic capturing, automatic grinding.The uniform magnetic force of mill distributes and special magnetic force absorption improves the sealed precision that is ground working face greatly, more helps precise finiss.The mill that is embedded with the strong bar magnet of rare earth cooperates with the diamond dust bistrique, more helps the uncolled steam grinding-in of valve that has.The diamond dust bistrique adopts self-adhesion sand paper, more helps the grinding of carbide alloy mouth.In addition, in light weight, the compact conformation of the utility model is suitable for narrow space and uses, and is easy to operate, need not assemble, and need not frequently unclamp in the grinding, the locking positioning screw, reduced working strength of workers.
