Abstract
The invention belongs to the technical field of tools and clamps and relates to a self-centering internally-tensioning drilling device. The self-centering internally-tensioning drilling device comprises a drill jig plate. A barrel plate is fixed to the bottom face of the drill jig plate. A conical activity space is formed in the rotation center of the barrel plate. A taper mandrel is arranged in the conical activity space. The upper end of the taper mandrel penetrates the drill jig plate and extends upwards. A threaded portion at the upper end of the taper mandrel is sleeved with a washer and connected with a fastening nut. Multiple mounting holes are uniformly formed in the circumferential surface of the barrel plate in the radial direction. A through hole is formed in the outer side of each mounting hole in a coaxial manner. The inner diameter of each through hole is smaller than that of the corresponding mounting hole. A compression spring and a ball head jacking pin are arranged in each mounting hole. The self-centering internally-tensioning drilling device is simple and reasonable in product structure; the taper mandrel matched with the ball head jacking pins is adopted, so that the purpose of tensioning workpieces is achieved; through the conical surface effect of the taper mandrel, radial adjustability of the ball head jacking pins is achieved, and thus the workpieces different in inner diameter are tensioned; and the application scope of the self-centering internally-tensioning drilling device is effectively widened.
Description
Technical field
The invention belongs to technical field of tooling clamps, it is related to one kind and makes intracardiac swelling drilling equipment by oneself.
Background technology
Before revolving body end flanges bore operation, need to carry out effective Set and Positioning to workpiece, in order to can be to workpiece
Accurately and reliably processed.By the way of revolving body workpieces general fixation using endoporus in Set and Positioning, existing revolving body
End flanges drilling-hole positioning device can only be realized the workpiece to specific model and carry out clamping fixing when using, and applicable surface compares
Narrow；Recently, there is also some on the market for the fixing frock clamp of various model revolving body clampings, most complex structure, life
Product manufacturing cost is higher, and follow-up use cost is larger.
Content of the invention
The present invention is directed to the problems referred to above, provides one kind to make intracardiac swelling drilling equipment by oneself, this apparatus structure advantages of simple, energy

Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is further described.
In Fig. 1, including bushing plate 1, drill bushing 2, through hole 3, conical core shaft 4, bulb ejector pin 5, hold out against end 5-1, force side 5-
2nd, compression spring 6, clamp nut 7, packing ring 8, workpiece 9, cylinder plate 10, taper activity space 11, installing hole 12 etc..
As shown in figure 1, the present invention is one kind making intracardiac swelling drilling equipment by oneself, including bushing plate 1, described bushing plate 1 bottom
Cylinder plate 10 is fixed in face, and the centre of gyration of cylinder plate 10 is provided with taper activity space 11, arranges in described taper activity space 11
Conical core shaft 4, the upper end of conical core shaft 4 upwardly extends through bushing plate 1, and the sheathed packing ring in threaded upper ends portion 8 of conical core shaft 4 is simultaneously
Connect clamp nut 7, the circumferential surface of described cylinder plate 10 radially uniform some installing holes 12, the outside of installing hole 12 is coaxial
Setting through hole 3, the internal diameter of through hole 3 is less than the internal diameter of installing hole 12, setting compression spring 6 and bulb ejector pin 5, institute in installing hole 12
State compression spring 6 one end and hold out against on bulb ejector pin 5, the other end holds out against on the bottom hole plate of installing hole 12, described bulb ejector pin 5
Hold out against end 5-1 stretch out from through hole 3, the force side 5-2 of bulb ejector pin 5 holds out against on the conical surface of conical core shaft 4.
If being laid with dry hole on bushing plate 1, in each boring, all it is equipped with drill bushing 2, drill bushing 2 upper end kink
