Abstract
A cutter structure for processing a bidirectional ring groove comprises a cutter arbor, a cutter block, and a cutter pressing bolt. The cutter block is installed in a square hole on the inner side of the top end surface of the cutter arbor; the cutter block is compressed on the cutter arbor through the cutter pressing bolt; cutting edges at two ends of the cutter block are positioned on the same side; the length of the cutter block is less than the breadth between an inner ring groove and an outer ring groove of a processed workpiece; the square hole for installing the cutter block is transversely formed on the inner side of the top of the cutter arbor; and when the cutter block is installed, the cutting edges at two ends of the cutter block extend out of the square hole on the cutter arbor in a bilateral symmetry manner. By adopting the method that the double-edge composite cutter block is installed on the cutter arbor, cutter clamping can be accomplished at one time, so as to accomplish the processing of the inner ring groove and the outer ring groove of the workpiece, eliminate the axial dimension error of the inner ring groove and the outer ring groove, and ensure the processing precision of the workpiece.
Description
Technical field
The utility model belongs to field of machining, relates to a kind of cutter, relates in particular to a kind of cutter structure of processing two-way annular groove.
Background technology
At present, domestic enterprise tends to relate to two-way cannelure processing work in machining, and the workpiece of processing this inside and outside annular groove adopts inside and outside two different grooving cutters mostly, and inside and outside annular groove is processed in clamping cutter processing at twice respectively.Add man-hour, the axial dimension error of twice clamping generation is uncontrollable.Simultaneously, twice clamping cutter, dress cutter, the toolsetting time is longer, influences operating efficiency.Therefore, need a kind of new cutter structure of development to address this problem, make its clamping cutter, finish the processing of inside-and-outside ring groove, eliminate the axial dimension error of inside-and-outside ring groove.
The utility model content
The purpose of this utility model is to provide a kind of compact conformation, convenient mounting and clamping, and service-strong is used to process the cutter structure of two-way annular groove.
The utility model can take following technical scheme to achieve the above object: the cutter structure of processing two-way annular groove comprises: knife bar, cutter piece, push type broach screw; Cutter piece 2 is packed in the inboard square hole of knife bar top end face, on the cutter piece of push type broach screw in compression in knife bar; Make cutter piece two ends cutting edge in the same side.
The cutter block length should be less than the width between processing work inner groove and the outer groove.
The inside top of knife bar is horizontally arranged with the square hole of the cutter piece of can packing into, and the cutting edge left-right symmetry at its two ends is stretched out in knife bar square hole outer end.
The beneficial effects of the utility model are: the operator takes to install one the method for twolip compound knife block on a knife bar, can once finish the clamping cutter, thereby finish the processing of the inside and outside annular groove of workpiece, eliminate the axial dimension error of inside and outside annular groove, guaranteed the machining accuracy of workpiece.
Description of drawings
Fig. 1 processes the schematic diagram of the cutter structure of two-way annular groove for the utility model.
Fig. 2 processes the cutter structure A-A profile of two-way annular groove for the utility model;
Fig. 3 processes the cutter structure processing inner groove a schematic diagram of two-way annular groove for the utility model;
Fig. 4 processes the cutter structure processing outer groove b schematic diagram of two-way annular groove for the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing: as Fig. 1～shown in Figure 4, the cutter structure of processing two-way annular groove comprises knife bar 1, cutter piece 2, push type broach screw 3.Cutter piece 2 is packed in the square hole of knife bar 1 inside top, the cutting edge left-right symmetry at its two ends is stretched out in knife bar 1 square hole outer end.With push type broach screw 3 cutter piece 2 is pressed in the knife bar 1.Cutter piece 2 two ends cutting edges are in the same side, and cutter piece 2 length should be less than the width between processing work inner groove a and the outer groove b.
Add man-hour, knife bar 1 axially enters between inner groove a and the outer groove b, processes after the axial location.During turning outer groove b, the processing of (away from the part center) feed radially outward outer groove b is to the groove depth size; After finishing the processing of outer groove b, knife bar 1 is axially motionless, and directly radially inside (approaching the part center) feed processing inner groove a is to the groove depth size; Because two ends cutter head direction unanimity, part is once adorned cutter and just can be finished the inner groove a on the annular groove, the processing of outer groove b smoothly by normal direction of rotation rotation.
Like this, the operator takes to install one the method for twolip compound knife block on a knife bar, just can once finish the clamping cutter, thereby finish the processing of the inside and outside annular groove of institute's processing work, eliminate the axial dimension error of inside and outside annular groove, guaranteed the machining accuracy of workpiece effectively.
