Motor gun body is affixed, and cutter head is symmetrical arc triangular structure, and planetary gear engages with internal tooth wheel seat, internal gear with it is planetary
Radius ratio R/r is 4 or 4/3.
Preferably, both cutter head and planetary gear are to be arranged concentrically, cutter head and planetary gear are inclined compared to drive shaft
The heart is set.
Preferably, being additionally provided with chip area on cutter head.
Preferably, drive shaft is provided with bearing with internal tooth wheel seat junction.
Preferably, cutter head front end is provided with the positioning drill of certralizing ability.
Preferably, drill is to be arranged concentrically with drive shaft.
The beneficial effects of the utility model are：The utility model devises a kind of square hole drilling machine, using planetary gear and
The movement locus that internal gear is produced in internal gear according to certain fit system, the planetary gear for making during at a fully engaged rotation, then
Plus the cutter head of arc triangle shape structure, square opening can be just cut out, and chip area is provided with cutter head, can be in fluting
When the scrap that produces exclude in time, prevent cutter head stuck.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figures 1-8, square hole line box machine of the present utility model includes motor gun body 1 and robs the driving of body 1 by motor
Square auger cutter head assembly 2, square auger cutter head assembly 2 includes being provided with internal gear 7, knife in tool rest and internal tooth wheel seat 8, internal tooth wheel seat 8
Seat includes cutter head 4, planetary gear 9 and the drive shaft 5 of Integral design, and cutter head 4 is located at tool rest front end, and planetary gear 9 is located at cutter head 4
Rear end, drive shaft 5 is affixed with motor gun body 1, and cutter head 4 is symmetrical arc triangular structure, and planetary gear 9 is engaged with internal tooth wheel seat 8,
Internal gear 7 is 4 or 4/3 with the radius ratio R/r of planetary gear 9.
Cutter head 4 and planetary gear 9 both to be arranged concentrically, cutter head 4 and planetary gear 9 are compared to drive shaft for bias sets
Put.Chip area 10 is additionally provided with cutter head 4, chip area 10 can exclude scrap, prevent that cutter head is stuck.
Drive shaft 5 is provided with bearing 6 with the junction of internal tooth wheel seat 8.
The front end of cutter head 4 is provided with positioning drill 3, and, with drive shaft to be arranged concentrically, positioning drill 3 is in operation for positioning drill 3
Play a part of to position and support, in operation, drilling is first positioned on wall by positioning drill, then bored by cutter head
Square hole.
The design principle of the utility model planetary gear and internal gear is：
If little gear O1In fixed gear wheel O2Pure rolling is inside done, size tooth radius is respectively R and r.A is little gear
On an eccentric point, eccentric throw O1A=e.From kinematic principle:
(1)：
xA=(R-r) cos α+ecos β
yA=(R-r) sin α-esin β
When little gear does pure rolling, R α=r (alpha+beta) substitute into formula (1) and obtain:
(2):
Formula (2) is done into nondimensionalization treatment, X=x is madeA/ r, Y=yA/ r, γ=R/r, η=e/r, then have
X=(γ -1) cos α+η cos { (γ -1) α }
Y=(γ -1) sin α-η sin { (γ -1) α }
The rail of eccentric point A when can easily draw out different parameters by computer drawing software DrawTool
Mark, is trajectory diagram shown in Fig. 6 when γ=4, η=0.4, is trajectory diagram shown in Fig. 7 when γ=4/3, η=3.5.As can be seen here
Square groove can be cut out during when γ=4, η=0.4 or when γ=4/3, η=3.5.
The above is only preferred embodiment of the present utility model, is come for those skilled in the art
Say, on the premise of the utility model principle is not departed from, some improvement can also be made, it is new that these improvement also should be regarded as this practicality
The protection domain of type.
