Abstract

Disclosed is a tool post for bidirectional planning suitable for planning work pieces, in particular for planning metal work pieces. The utility model is composed of a clapper box of the front and back stops, a clapper, an electric magnet, a spring and a planer whose front part and back part are provided with cutter heads. When planning, the planer can swing front and back to enhance a cutter head, and the other cutter head is placed down to cut. The utility model enhances the work efficiency of a planning machine.

Description

Tool post for bidirectional planing

The utility model relates to a kind of planing workpiece, the cutter holder device of the metal works of particularly planing.

The main motion of the planer of existing planing metal is a linear reciprocation, and two positive and negative strokes are arranged.The existing knife rest workpiece of planing on can only a stroke in main motion, another stroke of main motion is a null.Time in the planer idle stroke, the energy, wearing and tearing have been slatterned in vain.The way that existing metal-planing machine, shaping machine etc. address this problem is to accelerate the speed of main motion in idle stroke, though this can shorten the time of idle stroke, can not reduce wear and the energy.

The purpose of this utility model is that a kind of new knife rest will be provided, and it can both cutting workpiece in the stroke of the positive and negative both direction of main motion, improves the efficient of planer.

Buting iron is set respectively before and after the purpose of this utility model is achieved in that on the clapper box of knife rest, on clappers, installs one front and back planing tool of belt blade head all, when clappers lean against on the buting iron.A cutter head on the planing tool lifts, and another cutter head puts down, and the cutter head that puts down cuts workpiece.Buting iron before and after clappers alternately rely on, two cutter heads on the planing tool are also alternately planed.So just realized the alternately planing of knife rest at positive and negative both direction.

Knife rest provided by the utility model is owing in the stroke of the positive and negative both direction of main motion, can both plane to workpiece, so increase work efficiency one times than existing unidirectional planing knife rest.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the cutter frame structure schematic diagram.

Clapper box 1, fixedly buting iron 2, planing tool bar 3,, right cutter head 4, left cutter head 5, clappers 6, spring 7, mobile iron retaining 8, electromagnet 9, workpiece 10, bolt 11,12.

Planing tool bar 3 is fixed on the clappers 6.The symmetrical center line of planing tool bar 3 is by the axis of clappers 6.Cutter head of the left and right sides, bottom Ge An of planing tool bar 3, cutter head are symmetrically distributed, and electromagnet 9 is installed on the clapper box 1, and spring 7 is between clapper box 1 and clappers 6, and having the final say 6 is connected with clapper box 1 usefulness revolute pair.Mobile buting iron 8 can move it on clapper box 1 can adjust the pivot angle of knife bar 3 and the height of cutter head 4.

When electromagnet 9 energisings, clappers 6 overcome the thrust of spring 7 under the attraction of electromagnet 9.Be moved to the left, by on the fixing buting iron 2, at this moment cutter head 5 is lifted, cutter head 4 is put down planes to the work 10 that is moved to the left, after electromagnet 9 outages, clappers 6 move right under the promotion of spring 7, lean against on the mobile buting iron 8, at this moment cutter head 4 is lifted, and cutter head 5 is put down planes to the workpiece 10 that moves right, and the pivot angle θ of knife bar 3 decides on the size of knife rest, big more pivot angle θ is more little for knife rest, and pivot angle θ is generally below 5 degree.If the angle α of pivot angle θ and cutter head anterior angle γ and rake face and knife bar symmetrical center line have following relationship γ=-during (θ)/2 with the vertical plane of new rail head planing workpiece, clapper box 1 must be rotated an angle with respect to planker, the cutter head of not cutting so just can not be run into workpiece.

Claims

1, the utility model relates to a kind of planing workpiece, the cutter holder device of the metal works of particularly planing, and this installs by clapper box 1, fixedly buting iron 2, mobile buting iron 8, planing tool bar 3, cutter head 4,5, clappers 6, spring 7, electromagnet 9 are formed, and it is characterized in that:

The symmetrical center line of a, planing tool bar 3 is by the turning cylinder axis of clappers 6;

Left cutter head 5 and right cutter head 4 are arranged at the bottom of B, planing tool bar 3, and the rake face of cutter head 4 is towards the right side, and the rake face of cutter head 5 is towards a left side;

The angle α of the symmetrical center line of the anterior angle γ cutter head 4 of the pivot angle θ of C, planing tool bar 3, cutter head 4 and cutter head 5 and the rake face of cutter head 5 and planing tool bar 3 has following relationship:

γ=α- (θ)/2

D, clapper box 1 are connected with clappers 6 usefulness revolute pairs.
