The specific embodiment

As shown in Figure 1 and Figure 2, the non-cutter type two-sided bite lathe cutter of the utility model, comprise tool rest 1, last cutter holder 3, following cutter holder 7, the middle part of tool rest 1 is provided with fluting 10, cutter holder 3,7 is fixedly set in the upper and lower of tool rest 1 respectively up and down, and last cutter holder 3 and following cutter holder 7 are orthogonal, among Fig. 1, last cutter holder 3 vertically is provided with, and cutter holder 7 is horizontally disposed with down; The cutter head of cutter holder 3,7 is respectively arranged with bottom knife 5,6 up and down, and the point of a knife of last bottom knife 5,6 is in a straight line in vertical direction.

As shown in Figure 3, last bottom knife 5,6 is rhombus, and its tool cutting edge angle and auxiliary angle all are 45 °.

Distance between the point of a knife of last bottom knife 5,6 is greater than the thickness of part to be processed.

The length of the fluting 10 of tool rest 1 is greater than Cutting Parts length to be processed.

Last cutter holder 3 clamps solid screw 4 by upper slitter fixedlys connected with tool rest 1, and an end of last cutter holder 3 is provided with cutter holder and adjusts screw 2; Last cutter holder 3 is provided with regulating tank, adjusts screw 2 by regulating cutter holder, cutter holder 3 is moved up and down along regulating tank, thereby realization is to the fine setting of processing dimension.

Cutter holder trip bolt 8 was fixedlyed connected with tool rest 1 under following cutter holder 7 passed through, and an end of following cutter holder 7 is provided with down cutter holder and adjusts screw 9; Following cutter holder 7 is provided with regulating tank, adjusts screw 9 by regulating down cutter holder, can make down cutter holder 7 along the regulating tank move left and right, thereby realize the adjusting to last bottom knife 5,6 axis.

Go up bottom knife 5,6 relative positions by regulating the adjustment screw 2,9 of cutter holder 3,7 up and down, can changing, thus two-sided cutting when realizing to part.

The pitch of cutter holder adjustment screw 2,9 is 0.35mm up and down.

The top that last cutter holder is adjusted screw 2 is provided with sign graduation mark 21.

Adjust screw 2 when last cutter holder and rotate weeks, last cutter holder 3 moves 0.35mm in vertical direction.Sign graduation mark 21 is by 35 angles such as branch such as grade, and the adjustment amount of then adjusting the moving scale of screw 2 revolutions is 0.01mm.

The point of a knife of last bottom knife 5,6 keeps point-blank in vertical direction, and the part of can cancelling each other reduces the distortion of part at the cutting force of vertical direction, reaches best cutting effect.

The point of a knife of bottom knife 5,6 keeps method point-blank to be on the utility model:

Earlier tool rest 1 is tightened at tool setting gauge, cutter holder 3,7 is fastening with tool rest 1 respectively up and down again, point of a knife vertical line with cutter 5 is a benchmark, adjusting rod is penetrated down cutter holder to be adjusted in the adjustment hole of screw 9, turn down cutter holder and adjust screw 9, by screw thread thrust cutter holder 7 along continuous straight runs are moved, thereby the point of a knife of bottom knife 5,6 is consistent in vertical direction.

The tool cutting edge angle of bottom knife 5,6 and auxiliary angle all are 45 ° on the utility model, the both sides blade can use as cutting edge, therefore, when processing parts, make the feeding of cutter forward be cut to size earlier, press original route feed reversing subsequently to initial position, can finish a cutting step like this, and lathe and cutter do not need to make the cutter relieving action, and therefore, the non-cutter type two-sided bite lathe cutter of the utility model can use on all kinds of lathes.

The method that the utility model is adjusted processing dimension is:

Size and tolerance according to part to be processed, adjusting rod is penetrated cutter holder to be adjusted in the adjustment hole of screw 2, turn cutter holder and adjust screw 2, by screw thread thrust cutter holder 3 is moved in the vertical direction, and measure, thereby make cutter 5 reach appointed positions by special-purpose tool setting gauge block or tool setting gauge.
