Abstract
The utility model relates to a novel integrated head three-point dwelling jig, which relates to the technical field of woodworker dwelling jigs, and comprises a central positioning point, a main cutting edge, scribing edges, a cuttings chute and a bit main body, wherein the central positioning point is arranged on the central position of the front end of the bit main body, a plurality of scribing edges are uniformly distributed on the edge of the front end of the bit main body, the main cutting edge is arranged between the central positioning point and the scribing blades, a plurality of cuttings chutes are arranged on the bit main body, and the central positioning point adopts a design of a positioning point with higher strength; an active face of the main cutting edge adopts a diagonal cutter; each scribing edge adopts a transitional curve design; and the width of each cuttings chute is large. The novel integrated head three-point dwelling jig has small cutting force, is difficult to vibrate, has better finish, higher quality of the hole, longer service life and better impact resistance, and can be suitable for the cutting of high rotation speed and large amount of feed.
Description
Technical field:
The utility model relates to carpenter's gang drill technical field, is specifically related to a kind of novel whole head tricuspid gang drill.
Background technology:
Carpenter's gang drill is a kind of of furniture manufacturing machine, and kind is more, is used in a large number.But as Fig. 1-3., present tricuspid gang drill has the following disadvantages:
1, centralized positioning point a does not have cutting edge.Resistance is big during cutting, locatees inaccurately, and easily brill can not play a protective role to the hole partially.
2, main cutting edge b is a straight line, and down resistance is bigger during drilling, the easy passivation of cutting edge.Service life is short.
3, line sword c single-point contact cutting, anti-impact force is poor, and cutting edge collapses easily, and heat dispersion is poor, passivation easily.
4, chip area d is more smooth, and the helicla flute helical angle is less, and the chip removal performance is bad, and the endoporus volume is cut poor performance, and wood chip of running out and endoporus friction are burnt with endoporus easily.
The utility model content:
The purpose of this utility model provides a kind of novel whole head tricuspid gang drill, the little difficult generation vibration of its cutting force, and fineness is better, and the quality in hole is higher, and the life-span is longer, and impact resistance is better, can adapt to the cutting of high rotating speed roughing feed amount.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises centralized positioning point 1, main cutting edge 2, line sword 3, chip area 4 and drill main body 5, drill main body 5 front end centers are provided with centralized positioning point 1, uniform several line swords 3 of drill main body 5 front edges, be provided with main cutting edge 2 between centralized positioning point 1 and the line sword 3, drill main body 5 is provided with several chip areas 4.
Described centralized positioning point 1 adopts the higher locating tip Intensity Design of more traditional three gang drills.
The sword face of described main cutting edge 2 adopts oblique sword.
Described line sword 3 adopts the easement curve design.
More traditional three gang drills of the width of described chip area 4 are bigger.
The little difficult generation vibration of the utility model cutting force, fineness is better, and the quality in hole is higher, and the life-span is longer, and impact resistance is better, can adapt to the cutting of high rotating speed roughing feed amount.
Description of drawings:
Fig. 1 is the structural representation of background technology,
Fig. 2 is the A portion structure for amplifying schematic diagram of Fig. 1,
Fig. 3 is the left view of Fig. 1,
Fig. 4 is a structural representation of the present utility model,
Fig. 5 is the B portion structure for amplifying schematic diagram of Fig. 4,
Fig. 6 is the left view of Fig. 4.
The specific embodiment:
With reference to Fig. 4-6, this specific embodiment is by the following technical solutions: it comprises centralized positioning point 1, main cutting edge 2, line sword 3, chip area 4 and drill main body 5, drill main body 5 front end centers are provided with centralized positioning point 1, uniform several line swords 3 of drill main body 5 front edges, be provided with main cutting edge 2 between centralized positioning point 1 and the line sword 3, drill main body 5 is provided with several chip areas 4.
Described centralized positioning point 1 adopts the higher locating tip Intensity Design of more traditional three gang drills.Accurate positioning is difficult for deflection, cutting is more brisk, the little difficult generation vibration of cutting force, and fineness is better, and the quality in hole is higher, and the life-span is longer.
The sword face of described main cutting edge 2 adopts oblique sword.Have higher cutting security performance, down drilling is easier in high-speed machining process, and impact resistance is better.
Described line sword 3 adopts the easement curve design.Changed the situation of original line sword single-point contact cutting, the impact resistance of line sword is better, the cutting resistance of longer service life, working angles is littler, can adapt to the cutting of high rotating speed roughing feed amount.
More traditional three gang drills of the width of described chip area 4 are bigger.Chip removal is more smooth.Can produce bigger helical angle by grinding, easier chip removal, in the working angles, positive rake angle is bigger, and cutting force is littler.To solid wood processing highly significant.
The little difficult generation vibration of this specific embodiment cutting force, fineness is better, and the quality in hole is higher, and the life-span is longer, and impact resistance is better, can adapt to the cutting of high rotating speed roughing feed amount.
