The specific embodiment
According to accompanying drawing the specific embodiment of the utility model is done a detailed explanation below.
Embodiment
According to Fig. 1, Fig. 2 and shown in Figure 3; The described automatic drilling machine of present embodiment includes rig seat board 8; Motor 7 and drill bit 14, described motor 7 is fixedly installed on the rig seat board 8, and the output shaft of described motor 7 is connected with spline housing 9; Spline housing 9 is coaxially connected with splined shaft 10, and described drill bit 14 is connected with splined shaft 10 other ends through drill chuck 13; Described splined shaft 10 middle parts are socketed with axle sleeve 12, and splined shaft 10 is connected through bearing 11 with axle sleeve 12, and axle sleeve 12 also is connected with slide block 17, and described rig seat board 8 is provided with the chute 19 that is complementary with slide block 17; Described slide block 17 also is connected with connecting rod 18, and connecting rod 18 is connected with and drives its drive unit along drill bit 14 axially-movables.
Described drive unit is arranged on rig seat board 8 belows, and described connecting rod 18 passes rig seat board 8 and links to each other with drive unit.
Described drive unit includes and drives cylinder 20, and the piston rod that drives cylinder 20 links to each other with connecting rod 18, and driving cylinder 20 links to each other with air pump.
Described rig seat board 8 belows also are provided with the travel switch 16 that is triggered by connecting rod 18.
Described chute 19 is a dovetail groove.Slide block 17 and chute 19 coupling and slide block 17 each other can endwisely slip and can not break away from chute 19 along chute 19.
The described automatic drilling machine of embodiment is connected with the frame 1 of drilling machine through an end of rig seat board 8; Frame is provided with coil pipe holder 2; Coil pipe holder 2 is provided with the hold down gag 4 that is used for fixing coil pipe 3; Hold down gag 4 includes pressing plate 42 and the snap close 41 hinged with coil pipe holder 2, and pressing plate 42 is pushed down coil pipe 3 from coil pipe 3 tops, and pressing plate 42 cooperates clamping that coil pipe 3 is completely fixed with snap close 41.Described coil pipe holder 2 two ends and coil pipe 3 sweep shapes are complementary, and are convenient to place rapidly and accurately coil pipe 3.
Described coil pipe holder 2 is provided with the through hole that supplies drill bit 14 to pass, and is provided with drill bushing 15 in the through hole.Because splined shaft 10 is longer, it is spacing to use 15 pairs of drill bits of drill bushing 14 to carry out, and produces shake when reducing drill bit 14 idle running.
