The specific embodiment
According to accompanying drawing the specific embodiment of the utility model is done a detailed explanation below.
According to Fig. 1, Fig. 2 and shown in Figure 3; The drill feed of the described automatic drilling machine of present embodiment comprises the spline housing 9 that links to each other with motor 7 output shafts; With the spline housing 9 coaxial splined shafts that are slidingly connected 10, the other end of splined shaft 10 is through drill chuck 13 and 14 coaxial linking to each other of drill bit; Described splined shaft 10 middle parts are socketed with axle sleeve 12, and axle sleeve 12 two ends are connected through bearing 11 with splined shaft 10; Described axle sleeve 12 is connected with and drives its driver part along splined shaft 10 axially-movables.
Described motor 7 is fixed on rig seat board 8 tops, and described driver part is arranged on rig seat board 8 belows; Described axle sleeve 12 links to each other with driver part through connecting rod 18, and described connecting rod 18 passes from rig seat board 8.
Described 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 driver part is air pressure or hydraulic drive mechanism.Be preferably the air pressure driving mechanism, driver part as shown in Figure 3 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.
Described control drives the air pump and the motor 17 of cylinder 20 work and is controlled by same controller.Use below in conjunction with the utility model further specifies its operation principle.
At first, coil pipe 3 is placed on the coil pipe holder 2, then uses fixedly coil pipe 3 of hold down gag 4.After coil pipe 3 fixing the completion, start power supply, controller control motor 17 rotates; Splined shaft 10 promptly drives drill bit 14 to begin to rotate, and controller drives air pump work immediately, makes driving cylinder 20 promote connecting rods 18 drive axle sleeves 12 and moves to drill bit 14 directions; Simultaneously slide block 17 moves to oblique upper along chute 19; Splined shaft 10 promptly drives 14 pairs of coil pipes 3 of drill bit and punches, and when punching finishes, drives cylinder 20 promotion connecting rods 18 and continues to move to connecting rod 18 shake-up travel switches 16; Then controller control air pump makes and drives cylinder 20 and promote connecting rods 18 return motions, return back to initial position to connecting rod 18 after controller control motor 17 shut down.Unclamp hold down gag 4 at last, take out the coil pipe 3 that finishes of holing and get final product.
