Correction accessory of slotting tool

Abstract

The invention discloses a correction accessory of a slotting tool. The correction accessory comprises a locating block, the locating block is connected with the slotting tool, and a locating face on the locating block is perpendicular to a cutting edge on the front tool face of the slotting tool. A measuring head of a dial indicator abuts against the locating face. The measuring head of the dial indicator abuts against the locating face, and then the slotting tool and the locating block are pushed to move in the feeding direction together. After the read difference value on the dial indicatoris checked, the slotting tool and the locating block are rotated, and then the slotting tool and the locating block are pushed again to move in the feeding direction together until the read differencevalue on the dial indicator is close to zero. At this moment, the front tool face of the slotting tool is perpendicular to the feeding direction of the slotting tool, the angle of the slotting too isaccurately adjusted, and it is ensured that a machined key groove meets the design requirement.

Description

technical field [0001] The invention relates to the field of keyway processing equipment, in particular to a correction aid for inserting a knife during keyway processing. Background technique [0002] The slotting knife of the CNC gear shaping machine reciprocates up and down to cut metal. The slotting knife can be used to process the tooth profile of gears and racks, and can also be used to process keyways, such as Figure 1a and 1b As shown, the cross-section perpendicular to the length direction of the inserting knife commonly used in the market is trapezoidal. The inserting knife 1 includes front and rear knife surfaces A and a parallel to each other. Surface B, where the bottom edge of the rake face A is the cutting edge A1, and the length of the bottom edge of the rake face A is greater than the length of the bottom edge of the flank face A. When the keyway 3 to be processed on the shaft 2 is actually processed, the rake tool is required Surface A is perpendicular to...

[0002] The slotting knife of the CNC gear shaping machine reciprocates up and down to cut metal. The slotting knife can be used to process the tooth profile of gears and racks, and can also be used to process keyways, such as Figure 1a and 1b As shown, the cross-section perpendicular to the length direction of the inserting knife commonly used in the market is trapezoidal. The inserting knife 1 includes front and rear knife surfaces A and a parallel to each other. Surface B, where the bottom edge of the rake face A is the cutting edge A1, and the length of the bottom edge of the rake face A is greater than the length of the bottom edge of the flank face A. When the keyway 3 to be processed on the shaft 2 is actually processed, the rake tool is required Surface A is perpendicular to the feeding direction of slotting knife 1, and slotting knife 1 is installed on the main shaft 4 of the CNC gear shaping machine. The knife face A is perpendicular to the feed path of the inserting knife 1, and the accuracy of manual adjustment is low, which will cause the machined keyway to be deep on one side and shallow on the other side, which will directly lead to the scrapping of the workpiece to be processed
