Abstract
The utility model relates to a small-sized valve grinding machine which comprises a power portion, a transmission portion and a grinding portion. The power portion need no external power supply and adopts a 12V rechargeable battery for providing power, meanwhile ensuring the safety. The transmission portion comprises the following driving mediums: a motor connecting joint, a connecting rod and a universal joint, and all the parts are inserted with one another by fast joints for transferring the torsional moment. The grinding portion is provided with a corresponding abrasive disk or a locating and adjusting rotary table according to the size of the valve required to be ground. The utility model is the fast, high-efficient and portable small-sized valve grinding machine with small size and high grinding precision.
Description
Technical field
The utility model relates to the online prosthetic device of valve, is specifically related to a kind of valvelet grinder of the online reparation of valve of the DN20-DN150 of being applicable to bore, belongs to International Classification of Patents B24B37/00 " lapping machine or device " technical field.
Background technology
Valve grinding machine of the prior art, the general external power supply that all needs 220V, employing is the next fastening mostly between its driving member and the abrasive article, generally often will equip with other instrument the grinding of spool and realize.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of small-sized, portable small-sized valve grinding machine that can online reparation is provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of portable small-sized valve grinding machine, by power section, running part and working portion is that the grind section branch is formed, the top of grinder is power section---hand is held rifle formula direct current generator, pegs graft by the extension bar of motor connector and valve running part, and extension bar and universal joint are pegged graft; Universal joint is fastening by the mill of fillister head screw and means of abrasion, makes the abradant surface of mill can become needed angle with the transmission axis.
Described mill is adjustable plain grinding dish, and mill is provided with four location long slot bores, snaps in locating shaft in the long slot bore by hexagon socket cap head screw; Be with directive wheel on the locating shaft, locating shaft can move in long slot bore.
Between described connector and extension bar, extension bar and the universal joint, all adopt ready-packaged joint to transmit moment of torsion.
Between described universal joint and the mill, and between mill and the locating shaft, all adopt corresponding screw upper fastening.
Direct current generator can directly insert universal joint by the motor connector, does not use extension bar, makes the transmission distance for the shortest, to be adapted to the situation of narrow operating space.
The utlity model has following beneficial effect:
1. use the 12V safe voltage, for power plant, chemical enterprise, and iron and steel such as cabin constitutes and moist operating environment is particularly important.Provide rechargeable battery for oneself power is provided, need not field power supply, also exempted annexes such as plug, socket.
2. omitted the comparatively complicated driving member of bevel gear equity, structure is simpler, and machine is miniaturization more.
3. all adopt the plug of standard ready-packaged joint to connect between the driving member, can change combination arbitrarily, rapidly and efficiently, safe more convenient during use.
4. adopt that screw is upper to be fastenedly connected, can avoid smallclothes such as nut, pad to come off, slip into valve body or pipeline, cause adverse consequences.
Description of drawings
Accompanying drawing is the overall structure schematic diagram of the portable small-sized valve grinding machine of the utility model.
Among the figure: 1, locating shaft, 2, directive wheel, 3, nut, 4, hexagon socket cap head screw, 5, mill, 6, nut, 7, fillister head screw, 8, universal joint, 9, extension bar, 10, connector, 11, hand holds rifle formula direct current generator.
The specific embodiment
Referring to accompanying drawing, portable small-sized valve grinding machine, the employing rotating speed can be regulated, the hand of low-voltage 12V is held rifle formula direct current generator 11, by the lower end of connector 10, inserts extension bar 9.This extension bar 9, the several of processing varying length are a cover, to adapt to different operating spaces and working condition requirement.When the operating space is narrow and small, connector 10 directly can be inserted universal joint 8, make the transmission distance for the shortest.Extension bar 9 inserts universal joint 8, and universal joint 8 is upper fastening by fillister head screw 7 and mill 5.Select suitable adjustable plain grinding dish or entity plain grinding dish for use; If use the former, directive wheel locating shaft 1 is moved in the elongated slot locating hole, be adjusted to the optimum position after, make the upper fastening of locating shaft 1 and mill 5 with hexagon socket cap head screw 4.Telescopic directive wheel 2 limits the sand paper plane that mills 5 lower surfaces are pasted, and forms best break-in face with valve port or spool to be ground.Plain grinding dish 5 is that to be processed into several adjustable plain grinding dishes that diameter do not wait be one group, to adapt to the valve that the different size needs grind.Design has the littler entity plain grinding dish of diameter to be used for the grinding reparation of smaller diameter valve in addition.
During grinding, the right hand is grasped machine, and forefinger colludes trigger action formula switch, motor 11 is rotated, and by connector 10, extension bar 9 and universal joint 8, make mill 5 follow rotation, and feel is adjusted the pressure that 5 pairs of valves of mill are treated flour milling, implements the on-line grinding reparation to valve.
