Specific embodiment
Hereinafter embodiments of the present invention are illustrated by particular specific embodiment, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages of the present invention and effect easily.
The invention will be further described with reference to the accompanying drawings and examples：
As shown in Fig. 15, a kind of drill gun module, including drill gun 12, the drill gun mounting seat 13 of installation drill gun 12 and the second liquid
Depression bar 16, second hydraulic stem 16 is provided with two, and two second hydraulic stems 16 are located at 13 centrage (drill gun of the drill gun mounting seat
12 axis) underface, the top per the second hydraulic stem of root 16 is all hinged with the bottom of the drill gun mounting seat 13, two
Centre position between two hydraulic stems 16 is vertically provided with studdle 17, is screwed with clamp nut 18 on studdle 17, fastens spiral shell
Support tube 19 is actively cased with the studdle 17 of female 18 top, the top of support tube 19 is fixed with the axis phase with drill gun 12
The vertical and support shaft 20 parallel with drill gun mounting seat 13；The drill gun mounting seat 13 includes the drill gun for clamping drill gun 12
Fixture 14 and slide 15；
The drill gun fixture 14 includes clamp base 1401 and the tailstock 1402 being arranged in clamp base 1401 and chuck,
The chuck can form the upper blocking seat 1403 of a circular folder hole and lower deck 1404 after including to be combined with each other；The tailstock
1402 arc groove is matched with the circular arc projection 1201 of 12 tail end of drill gun, and the circular arc projection 1201 is stung tightly, and drill gun 12 is bored
The cervical region 1202 of head end is clamped by the upper blocking seat 1403 and lower deck 1404, so as to fix and its pikestaff 12 clamping of drill gun
1203 upward；The slide 15 includes slide base plate 1501 and the ram 1503 being arranged on slide base plate 1501, the ram
1503 are provided with and can be fixed with the clamp base 1401, the fixture on slide block 1504 along its slide block 1504 slidably
One end of base 1401 is connected with the 3rd hydraulic stem 1502.
Further, second hydraulic stem 16 is provided with the scale 1601 of depression, laser engraving at corresponding scale 1601
There is scale value.As two second hydraulic stems 16 are all hinged with 1 mounting seat of drill gun, 13 bottoms, therefore, by adjusting two hydraulic pressure
The collapsing length difference of bar can realize the installation gradient of mounting seat 13, so that drill bit is directed at the diverse location of major axis 2, get out
The hole of various location；Herein using depression scale 1601 and corresponding scale value be for the ease of confirm mounting seat 13 peace
Dress inclination angle, its angle value is the arc-tangent value of the height difference with the ratio of two hydraulic pressure distance between tie rods of two hydraulically extensible bars.
Further, on the leading flank of two L-type steel plates 501, symmetrical graduation mark 602 is equipped with, in two L-type steel plates
The lateral surface of the support plate 6 between 501 is provided with arrow 603；When regulation support plate 6 is moved between two L-type steel plates 501, institute
The direction of arrow for stating arrow 603 can be conllinear to the symmetrical corresponding graduation mark 602 on two L-type steel plates 501.So design
When being to adjust support plate 6 using the collocation bolt of above-mentioned bar hole 50101, support plate 6 is made to lift in vertical direction exactly, to protect
The set location for demonstrate,proving breach 601 for clamping is accurate；Because when adjusting, can be according to arrow 603 and two L-type steel plates
Whether the symmetrical one group graduation mark 602 on 501 is collinearly lifted in vertical direction determining support plate 6 exactly.
Further, the clamp base 1401 is provided with screw rod mounting seat 1406, and the screw rod mounting seat 1406 is two
The hollow rectangular structure of side insertion, its two ends is provided with rolling bearing；One end of screw rod 1405 sequentially passes through the rolling at two ends
Bearing, the other end is fixedly welded with hex nut, so as to by screw rod 1405 rotatably in screw rod mounting seat 1406
Portion, the screw thread of screw rod 1405 stretch out the through hole of 1406 both sides of screw rod mounting seat and with the sliding sleeve for covering in screw rod mounting seat 1406
1407 thread connection, drive sliding sleeve 1407 to move back and forth.1406 hollow structure of screw rod mounting seat for arranging herein can be very perfect
Ground is by screw rod 1405 on 1 fixture of drill gun, close or remote come manual adjustment drill gun 1 by turning the hex nut being welded
From major axis 2, and screw rod 1405 is matched with threaded sliding sleeve 1407, and itself has fine adjustment function, makes degree of regulation higher.
Further, the sliding sleeve 1407 be symmetrically arranged on two with screw-threaded counterbore 1408, dogbolt (not shown)
It is screwed in the screw-threaded counterbore 1408 and by 1405 radial direction dieback of screw rod, is embedded with one and stretches in the end face that is screwed into of the dogbolt
Go out the cylindric rubber blanket (not shown) of its end face.After avoiding drill gun 1 from being conditioned and put in place, in drilling due between screw thread
The excessive or drilling dynamics in gap of cooperation is excessive to cause drill gun 1 to rock, or even 1405 stripped thread of screw rod, using dogbolt top
By screw rod 1405 is closely connected as a single entity with sliding sleeve 1407 while tight screw rod 1405 prevents 1405 fine rotation of screw rod,
So as to prevent drill gun from rocking；Additionally, closely can wrap up the screw thread of screw rod 1405 in cylindric rubber blanket, more efficiently prevent
Only screw rod 1405 is rotated.
Further, one end towards drill bit of the chuck is additionally provided with drill bushing 1409, the drill bushing 1409 and the lower card
Seat 1404 is connected as a single entity, and drill bushing 1409 is coaxial with the deck 1404 that is provided with arc groove., after drill gun 1 is installed, to bore
Head can be directly protruding in drill bushing 1409, play the important function for being oriented to and preventing drill bit beat in bit bore.
Further, one layer of rubber tube (not shown) is wrapped with outside the support shaft 20, and the rubber tube is provided with
The groove that some circles are evenly arranged.When the support shaft 20 is with the bottom connection of drill gun mounting seat 13, can with buffer shock-absorbing,
The bottom with mounting seat 13 is avoided when there is rigid collision, to damage the knot that is articulated and connected of the second hydraulic stem 16 and mounting seat 13
Structure.
Above-described embodiment only principle of the illustrative present invention and its effect, not for the restriction present invention.Any ripe
The personage for knowing this technology all can carry out modifications and changes without prejudice under the spirit and the scope of the present invention to above-described embodiment.Cause
This, those of ordinary skill in the art is complete with institute under technological thought without departing from disclosed spirit such as
All equivalent modifications for becoming or change, must be covered by the claim of the present invention.
