But such drill is because self structure reason exists following three shortcomings: the cutter 1, connecting by gear-box, overall structure is larger, is not suitable for processing in little space; 2, gearbox medium gear vibrations in the time of work are larger, the precision of impact boring; 3, the cost of gear-box is higher, is therefore unfavorable for reducing the price of product.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, can in little space, process, and also working stability, 90 ° of corner drills that cost is low.
The utility model solves the technical scheme that its technical problem adopts: a kind of 90 ° of corner drills, comprise fuselage, tool rest and the drive motors for driving tool rest to rotate are installed on fuselage, also include for tool rest being installed on to the telescopic arm on fuselage, on described telescopic arm, offer for tool rest and rotate the tool rest chamber of installing, on tool rest and drive motors output shaft, be arranged with respectively the belt wheel cooperatively interacting, between two belt wheels, tensioning has endless belt.
In order to ensure the smoothness of transmission between tool rest and drive motors output shaft, and the maximization of efficiency on power transmission, so tool rest is cylindrical-shaped structure, tool rest axially and being axially parallel to each other of drive motors output shaft.Columned tool-apron structure, is more suitable for and the socket of belt wheel, and rotates while installation and be more prone to.
For the belt wheel that ensures to be installed on tool rest is more stably worked, so offer the belt wheel chamber for holding belt wheel at tool rest chamber interior walls place, on linking arm, also offer the breach that perforation belt wheel chamber feed wheel lean out.Belt wheel is by breach and part is exposed on linking arm surface, and exposed part just can be wound around for endless belt tensioning, more stable by the effect of belt wheel cavity wall as for belt wheel.
Cutting tool installation manner is on tool rest, in order to guarantee stable and effectively cutter to be fixed on tool rest, so offer the jack plugging for cutter on tool rest and axially arrange and extend to the locking screw holes in jack perpendicular to jack, in this locking screw holes, clamping screw being installed.
In order to ensure that cutter can work in long and narrow space, so telescopic arm comprises the first telescopic arm and the second telescopic arm that are fixedly connected with by screw, described tool rest is installed on the first telescopic arm, and the second telescopic arm is fixedly installed on fuselage.By dismounting screw, to adjust relative position between the first telescopic arm and the second telescopic arm, thereby realize the relative position adjustment that tool rest is fixed a cutting tool.
Stable fixing in order to ensure between the first telescopic arm and the second telescopic arm, so offer two fixing threaded holes on the first telescopic arm, on the second telescopic arm, at least offer three fixing threaded holes, fixing threaded hole on the second telescopic arm is located along the same line, and on the first telescopic arm and the second telescopic arm, the spacing between the adjacent fixing threaded hole of two-phase all equates arbitrarily.
The beneficial effects of the utility model are: tool rest can be in the indoor rotation of tool rest, and under the effect of belt wheel and endless belt, tool rest is subject to the effect of drive motors output shaft and rotates, thereby can on the inwall of hole or groove, carry out the boring of 90 ° of corners.Due to the setting with transmission, not only save a large amount of installing spaces, make it adapt to more little space; And when work vibrations are less, stability and precision while improving boring are higher; In addition, can also save more production cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1,2,3, 4, the present embodiment comprises fuselage (owing to belonging to conventional structure, therefore in the accompanying drawings omit), tool rest 1 is installed, for driving drive motors 2 that tool rest 1 rotates and for tool rest 1 being installed on to the telescopic arm 3 on fuselage on fuselage.On telescopic arm 3, offer for tool rest 1 and rotate the tool rest chamber 311 of installing, on tool rest 1 and drive motors 2 output shafts 21, being arranged with respectively 4 tensionings of belt wheel 4, two belt wheel that match has endless belt 5.
In order to ensure the smoothness of transmission between tool rest 1 and drive motors 2 output shafts, and the maximization of efficiency on power transmission, so tool rest 1 is cylindrical-shaped structure, tool rest 1 is outer to be arranged with bearing and to be rotated and be installed in tool rest chamber 311 by this bearing, wherein being axially parallel to each other of axial and drive motors 2 output shafts 21 of tool rest 1.Simultaneously, in tool rest chamber, 311 inwall places offer the belt wheel chamber 312 for holding belt wheel 4, on linking arm 3, also offer and connect belt wheel chamber 312 feed wheel 4(herein for being positioned at the belt wheel 4 on tool rest 1) breach 313 that leans out, belt wheel is by breach 33 and part is exposed on linking arm 3 surfaces, and exposed part just can be wound around for endless belt 5 tensionings, be subject to effective restriction as for belt wheel 4 by belt wheel chamber 312 inwalls, thereby ensure when belt wheel 4 rotates more stable.
In order to guarantee stable and effectively cutter 6 to be fixed on tool rest 1, so offer the jack 11 plugging for cutter 6 on tool rest 1 and axially arrange and extend to the locking screw holes 12 in jack 11 perpendicular to jack 11, in this locking screw holes 12, clamping screw being installed.Therefore, when cutter 6 is inserted in jack 11 when interior, screw and push up by clamping screw to be pressed in cutter 6 surfaces, thus cutter 6 is locked on tool rest 1 securely.In addition, due to sometimes need to be in darker hole or groove internal drilling, so just need telescopic arm 3 to there is the feature of free-extension.For this reason, telescopic arm 3 comprises the first telescopic arm 31 and the second telescopic arm 32 that are fixedly connected with by screw 33, and tool rest 1 is installed on the first telescopic arm 31, and the second telescopic arm 32 is fixedly installed on fuselage.On the first telescopic arm 31, offer two fixing threaded holes 314, on the second telescopic arm 32, offer in three fixing threaded hole 321(accompanying drawings 2 and only draw two, the 3rd omission), fixing threaded hole 321 on the second telescopic arm 32 is located along the same line, and spacing between any two adjacent fixing threaded holes all equates.In the time need to changing the length of telescopic arm 3, as long as disassemble screw 33, and as required the position of fixing threaded hole 321 on fixing threaded hole 314 on the first telescopic arm 31 and the second telescopic arm 32 adjusted and alignd, and then being undertaken corresponding fixing by screw 33.
In the utility model, tool rest 1 can be in the interior rotation in tool rest chamber 31, under the effect of belt wheel 4 and endless belt 5, tool rest 1 is subject to drive motors 2 output shaft effects and rotates, by linking arm 3, tool rest 1 is stretched in the hole 71 on workpiece 7, then starts drive motors 2, drive motors 2 output shafts 21 by endless belt 5 by transmission of torque to tool rest 1, tool rest 1 rotates around self axis in tool rest chamber 311, and the cutter 6 on tool rest 1 can be holed on the inwall of this hole 71.Due to the setting with drive mechanism, conventional gears box structure, has not only saved a large amount of installing spaces relatively, makes it adapt to more little space; And when work vibrations are less, stability and precision while improving boring are higher; In addition, can also save more production cost.
