Abstract
The utility model relates to a self-control pull-rod drilling fixture, which is structurally characterized in that two fixing seats are arranged on two ends of the upper surface of a base and are internally and respectively provided with a cylindrical hole, screw holes on the upper surface of the two fixed seats are mutually vertical and communicated, the screw holes are internally provided with jack screws, each fixed seat is provided with a vertical hole and a horizontal hole, the vertical holes completely and vertically penetrate through the fixed seats and the base, the horizontal holes completely penetrates through the front and the rear end faces of the fixed seats, and drill bushings are respectively arranged on end sides of the vertical holes and the horizontal holes; an end side of the base is fixedly connected with an L-shaped jack screw support which is in threaded connection of jack screws, and the ends of the jack screws are connected with a top plate; and a groove is arranged on an upper surface on the other end of the base and is internally provided with a check block. The self-control pull-rod drilling fixture is used for positioning a pipe and a bushing in one step so that the close fit between the bushing and the pipe is ensured, drilling holes are preformed on an axis of the pipe, and four holes can be drilled in one step without secondary positioning. Therefore, both the drilling precision and the working efficiency are improved.
Description
Technical field
The utility model relates to a kind of self-control pull bar boring grab, when being used for holing on double-deck pipe, guarantees closely cooperating of bimetallic tube, makes on the axis that is drilled in pipe.
Background technology
Aluminum pipe is connected with high locked bolts with the concentric holes of lining, because aluminum pipe and lining are cylinder, the material of lining is again a steel alloy, never has suitable boring grab, holes on double-deck pipe, can only manual operations hole.Because it is pipe rolls easily, bad fixing, inclined to one side hole drill easily.Must guarantee during boring that aluminum pipe hole and bush hole are concentric, and perpendicular to the tubular axis line; Pipe two ends and lining fit tightly, and do not allow the gap, and are difficult to guarantee to be drilled on the axis of pipe by range estimation.There is not suitable clip that lining is fixed on the pipe that needs to install yet.
Summary of the invention
The purpose of this utility model provides a kind of self-control pull bar boring grab, this self-control pull bar boring grab one-time positioning pipe and lining, guaranteed closely cooperating of lining and pipe, be drilled on the axis of pipe, can once all bore four holes without the secondary positioning instant.Not only improve borehole accuracy, and improved operating efficiency.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of self-control pull bar boring grab, be provided with two holders at the base upper surface two ends, in holder, be respectively equipped with cylindrical hole, two cylindrical hole equal diameters and coaxial, vertical respectively at the upper surface of holder and communicate screwed hole, be provided with jackscrew in the screwed hole, on holder, also be provided with upright opening and lateral aperture, upright opening fully vertically runs through holder and base, lateral aperture runs through the front/rear end of holder fully, at the distolateral drill bushing that is respectively equipped with of upright opening and lateral aperture; At the jackscrew support of distolateral being fixedly connected with " L " shape of base, the jackscrew that is threaded on the jackscrew support, the jackscrew termination connects top board; Upper surface at the other end of base is provided with groove, places block in the groove.
This self-control pull bar boring grab adopts said structure, makes lining in the cylindrical hole that is placed on holder and pipe simultaneously axially and radially locate with jackscrew and baffle plate, block, thereby easily holes.Employing drill bushing location, thus the drilling accuracy requirement guaranteed.

Fig. 2 is the A – A cutaway view of Fig. 1.
The specific embodiment
As shown in Figure 1, a kind of self-control pull bar boring grab, be provided with two holders 2 at base 1 upper surface two ends, in holder 2, be respectively equipped with cylindrical hole 3, two cylindrical hole 3 equal diameters and coaxial, vertical respectively at the upper surface of holder 2 and communicate screwed hole 4, be provided with jackscrew 5 in the screwed hole, this jackscrew has guaranteed the radially rotation of pipe, also is provided with upright opening 6 and lateral aperture 7 on holder 2, and upright opening 6 fully vertically runs through holder 2 and base 1, lateral aperture 7 runs through the front/rear end of holder 2 fully, at the distolateral drill bushing 8 that is respectively equipped with of upright opening 6 and lateral aperture 7, this drill bushing 8 can replace with different models according to the diameter of drill bit, make the anchor clamps interchangeability good, drill bushing 8 has guaranteed the perpendicularity of boring simultaneously, once lining and pipe can be drilled through high efficiency; At the jackscrew support 9 of distolateral being fixedly connected with " L " shape of base 1, the jackscrew 5 that is threaded on the jackscrew support 9, jackscrew 5 terminations connect top board; Upper surface at the other end of base 1 is provided with groove, places block 11 in the groove.
