Detailed description of the invention
Embodiment
As shown in Fig. 1~3 and 5, a kind of automatic punch, including frame 1, buncher 2 and fixture 3, described fixture 3 liang
Side is provided with borehole drill construction, and described borehole drill construction includes the power that drive mechanism 4 is in transmission connection with described drive mechanism 4
Head assembly 5, the drill bit being arranged on described unit head assembly 5 outfan and the mounting seat being slidably connected with described frame 1;Described drive
Motivation structure 4 is fixedly installed in described frame 1, and described unit head assembly 5 is arranged in described mounting seat, described drive mechanism
Being connected by belt transmission between 4 with described unit head assembly 5, described mounting seat includes and the slide rail 11 in described frame 1
The slide 51, the lateral adjustments seat 52 being slidably arranged on described slide 51 that are slidably connected and be fixedly installed on described lateral adjustments
Vertical adjustment seat 53 on seat 52, is provided with back-moving spring (not shown) between described slide 51 and described frame 1, described
Back-moving spring one end is connected with described slide rail 11, and the other end is connected with described slide 51, and described unit head assembly 5 is arranged on described
On vertical adjustment seat 53, described slide 51 is provided with the lateral adjustments nut for regulating described lateral adjustments seat 52 position
54, described vertical adjustment seat 53 is provided with the vertical adjustment nut 55 for regulating described unit head assembly 5 height;
As shown in Figures 2 and 3, described buncher 2 outfan is provided with drive shaft 21, and described drive shaft 21 two ends are all provided with
Being equipped with cam pack 6, described cam pack 6 rolls connection by roller 61 has swing arm 7, with described in the middle part of described swing arm 7
Frame 1 is rotationally connected, and described swing arm 7 one end contacts with the mounting seat of described borehole drill construction and is used for driving described borehole drill construction in institute
Stating and move towards described fixture 3 in frame 1, back-moving spring can effectively ensure that swing arm 7 contacts with mounting seat, reaches the most reciprocal
The purpose of motion.
Specifically, as shown in Figure 4, described fixture 3 includes the first clamp body 31 and the second clamp body 32, described first folder
Concrete 31 are fixedly installed in described frame 1, hinged with described frame 1 bottom described second clamp body 32, described first fixture
Connected by spring between body 31 and the second clamp body 32, the face that described first clamp body 31 is relative with the second clamp body 32 sets
Being equipped with the cavity 33 for placing workpiece hole to be drilled, the side of described first clamp body 31 and the second clamp body 32 is provided with use
In stretching into the perforate 34 of drill bit, described perforate 34 connects with described cavity 33, described second clamp body 32 side be provided with for
Described second clamp body 32 is pressed on the hold-down mechanism on the first clamp body 31 body.Described hold-down mechanism includes being arranged on institute
Stating the compression cam 8 in the middle part of drive shaft 21, described compression cam 8 connects has compressor arm 9, described compressor arm 9 to rotate with frame 1
Connecting, described compressor arm 9 one end contacts with described second clamp body 32.
Operation principle is as follows: adjust lateral adjustments nut 54 and vertical adjustment nut 55 in advance, it is ensured that drill bit and fixture 3
On perforate 34 position corresponding;During original state, the mounting seat of the borehole drill construction of fixture 3 both sides and unit head assembly 5 away from
Fixture 3, the first clamp body 31 and the second clamp body 32 are in open configuration under the effect of spring and compressor arm 9.Start speed governing
Motor 2 and drive mechanism 4, put into workpiece to be punctured in the cavity 33 between the first clamp body 31 and the second clamp body 32,
Under the effect compressing cam 8 in buncher 2 drive shaft 21, compressor arm 9 swings thus the second clamp body 32 is pressed on the
On one clamp body 31, thus by Workpiece clamping in cavity 33;Drive mechanism 4 drives drill bit to rotate through unit head assembly 5, convex
Under the effect of wheel assembly 6, the swing arm 7 of fixture 3 both sides swings and promotes the mounting seat of fixture 3 both sides, unit head assembly 5 and drill bit
Sliding towards fixture 3, final drill bit carries out punching action to workpiece in stretching into perforate 34;Make at cam pack 6 after having punched
Under with, swing arm 7 resets, and under action of reset spring, mounting seat, unit head assembly 5 and boring also reset, and compressor arm 9 is convex in compression
Wheel 8 effect lower swing is away from the second clamp body 32, thus the second clamp body 32 separates with the first clamp body 31 under the action of the spring,
And then manually take out the workpiece after punching, and so forth, reciprocating frequence can be regulated by buncher 2.
Should be appreciated that specific embodiment described above is only used for explaining the present invention, be not intended to limit the present invention.By
What the spirit of the present invention was extended out obviously changes or changes among still in protection scope of the present invention.
