The specific embodiment

Below by accompanying drawing concrete structure of the present utility model is elaborated.Fig. 1 is the structural representation of the unit head of the utility model electric file; The power of unit head is by power shaft 12 input, and the output shaft that power shaft 12 can connect the power output shaft of electric wheel, electric hand drill or hand sand machine equal power device commonly used at present or directly adopt above-mentioned electric device is as power shaft 12.

Whole unit head shell 16 utilizes flange 20 and the fixing hole 19 on it to be fixed on the shell of above-mentioned power-equipment, forms electric file of the present utility model.As shown in Figure 1, the shell 16 of whole unit head is divided into two parts, in the latter half, power is by power shaft 12 inputs, and a pair of reduction gearing of process is slowed down and changed rotation direction, wherein, angle gear 14 is fixed on an end of power shaft 12, and bevel gear 13 is fixed on the main shaft 10, and angle gear 14 and bevel gear 13 are meshed, change the high rotating speed of power shaft 12 slow-speed of revolution of main shaft 10 into, also the rotation of the vertical direction of power shaft 12 is become the rotation of main shaft 10 horizontal directions simultaneously.Main shaft 10 is by bearing 10 and main shaft copper sheathing 11 vertical fixing, and main shaft 10 stretches into the first half of shell 16, and its upper end is rotating disk 17 fixedly, and drive rotating disk 17 rotates on horizontal plane.Rotating disk 17 drives a sets of transmission mechanism makes the rotation of rotating disk 17 become the reciprocating motion of power arm 6, and its structure as shown in Figure 2.

Fig. 2 is the power output structure schematic diagram in the unit head of the utility model electric file.The edge of rotating disk 17 is fixed with swivel joint 4, and swivel joint 4 links to each other with swing arm 15, and the end that swing arm 15 is connected with swivel joint 4 can rotate relative to swivel joint 4.One end of the other end of swing arm 15 and power arm 6 is connected, and also can relatively rotate by 5 joints simultaneously.The other end of power arm 6 is a chuck 1, and chuck 1 stretches out shell 16.Chuck 1 is provided with set bolt 2.

During use, 12 rotations of the driven by motor power shaft of dynamic power machine, angle gear 14 drives bevel gears 13 and slows down and rotate, and the rotation ratio of angle gear 14 and bevel gear is 4: 1, drives main axis rotation simultaneously and changes its direction of motion.Main shaft 10 drives rotating disk 17 and horizontally rotates, and rotating disk 17 is the motion modes according to the bent axle principle, and the position-limiting action by swing arm 15 and copper sheathing 3 becomes rotatablely moving of rotating disk 17 reciprocating motion of power arm 6.Copper sheathing 3 also reduces its sliding friction.Chuck 1 design of power arm 6 has square opening, is convenient to insert and fixing file.

That file has is square, flat, ellipse, semicircle, and the position shape of file in chuck 1 the inside may be circular or square, and be when it is clipped in the square opening of chuck 1, fixing by set bolt 2.Because in operating process, on chuck 1 during the angle of dress flat file file 90 degree, stressed on the file is on the limit of file, if circular it will turn, make the file dislocation, square opening is convenient to the file location, for the firm file that clamps, use two set bolts 2 fixing usually.

On PTO such as electric wheel, electric hand drill or hand sand machine, can also be arranged on varying speed switch.If the position of processing parts file is seldom, and is more accurate for the position that makes it, just must reciprocating speed be slowed down by varying speed switch, be convenient to grasp machining accuracy.

In order to operate accurately, at unit head shell 16 front ends a position block 8 is housed, position block 8 rear ends have bar hole 18, are fixed on the shell 16 by bolt 9.

During work, the front end of position block 8 props up workpiece or Work fixing device, considers the shape and the size of workpiece, and the bar hole 18 of position block 8 can be regulated front and back position block 8, makes the machined surface of the suitable workpiece in position of file.The front end of position block 8 props up workpiece or Work fixing device, also makes the electric file operation more stable simultaneously, improves machining accuracy.
