Description

A kind of electric tool in glass reinforced plastic pipe internal recessing hole

Technical field the utility model relates to a kind of electric tool.

Background technology is well-known, and the fiberglass pipeline is connected by some joint glass reinforced plastic pipes and forms, its key technology then be between the tube and tube connection whether firmly, do not leak, it is related to the application prospect of glass reinforced plastic pipe.Because the application scenario difference, connecting mode is also different.Wherein the connection of the tube and tube that axial tension is big is to adopt spigot-and-socket to connect, and promptly establishes three road grooves on glass reinforced plastic pipe socket (being minor diameter one end) outer wall, and wherein twice are used to establish O-ring seal, and another road is used to set up defences and only two saves the nylon rod that is tightly connected of throwing off.This strip nylon rod is to be inserted between two glass reinforced plastic pipes from the fore shaft that is located on the glass reinforced plastic pipe bellmouth (being major diameter one end), and nylon rod head and the tail two ends place and constitute locking key in the fore shaft after a week.This is located at fore shaft corresponding with the socket groove on the bellmouth wall is strip through-hole, and its radial section is approximately isosceles trapezoid, so that the nylon locking key is inserted.Present above-mentioned fore shaft be processed as hand labour, not only operating efficiency is very low, and the fore shaft that processes is very coarse, of poor quality, the assembling that influences locking key.

The summary of the invention the purpose of this utility model is to provide the electric tool in glass reinforced plastic pipe internal recessing hole of the high-quality and efficient rate of a kind of energy.The utility model mainly includes base, wheel, handrail, locating support, motor, fixed head, sharpening, connecting rod, screw mandrel, column, nut and handle.Wherein base below be provided with wheel, this electric tool can be moved on to the glass reinforced plastic pipe place by these wheels and process, to avoid carrying heavy glass reinforced plastic pipe.Be provided with handrail at this rear portion above base.Be provided with two groups of locating supports of certain intervals on base, two every group are herringbone, and their lower end is fixed on the base, and the upper end is a free end.Processed glass reinforced plastic pipe bellmouth one end can place in above-mentioned two groups of locating supports, and the mouth of pipe is towards the base rear portion.Motor is fixed on the tilting connecting plate, and this connecting plate lower end limit links to each other with the base rear portion by hinge, and the hinge axis of its level is parallel with the glass reinforced plastic pipe axis.The end limit on connecting plate top links to each other with an end of connecting rod by hinge, and the other end of this connecting rod links to each other with the lower end of screw mandrel.This screw mandrel passes and the nut of its engagement and the strip through-hole on column top from the bottom to top successively, and the upper end is provided with handle.Above-mentioned column is the channel-section steel that the lower end is fixed on the base rear portion.Above-mentioned nut is provided with two ends of minor axis radially of symmetry, and the other end of this two minor axis reaches respectively outside the through hole on the relative dual-side of column.The motor that is fixed on the connecting plate is coaxial to horizontal spindle that protracts and glass reinforced plastic pipe, and it links to each other with the axle of whetting a knife by shaft coupling, is fixed on a annular on whetting a knife spool its outer peripheral face of whetting a knife and establishes helical teeth shape blade, and this blade width is identical with the fore shaft width.

Add man-hour, the glass reinforced plastic pipe bellmouth is placed on two groups of locating supports, the sharpening of stretching out forward just is inserted in the glass reinforced plastic pipe.Move forward and backward base and make the aligning fore shaft position of whetting a knife, the handle of rotary screw rod upper end makes the screw mandrel elongation of nut bottom, and it orders about the motor connecting plate and horizontal plane angle dwindles, so the sharpening blade just contacts with the glass reinforced plastic pipe inwall.Open motor power, whet a knife and rotate the grinding tube wall, the while is the rotary screw rod handle again, makes the screw mandrel elongation gradually again of nut bottom, also move downward except that rotating so whet a knife, the glass reinforced plastic pipe that is in contact with it is worn into the strip through-hole that is the inclined-plane in two limits with the steel shaft line parallel.When reaching the fore shaft dimensional requirement, shut down, and then the backward rotation screw mandrel drives connecting plate motor and sharpening are mentioned, leave tube wall, pull back handrail and make base leave this pipe, be pushed into next root pipe again and process.

The utlity model has following advantage:

1. simple in structure, easy to operate.

2. high efficiency, the good and standard of the fore shaft quality that processes.

3. make the workman break away from heavy hand labour.
