Abstract
The invention relates to a positioning fixture for shaft hole drilling. The positioning fixture comprises a base, a bolt is fixedly installed in the middle of the base and sleeved with a compression spring, the upper end of the compression spring is connected with a pressing plate in an abutting mode, a guide groove is formed in the middle of the pressing plate, and the bolt penetrates through and extends out of the guide groove; a clamping part is arranged at the top end of the bolt and arranged in the guide groove in a press-fitting mode, an eccentric cam is hinged to one end of the pressing plate, a boss connected with the eccentric cam in an abutting mode is installed on the base, a handle is fixedly connected to the eccentric cam, a press-fitting part protruding and extending downwards is arranged at the other end of the pressing plate, a first abutting face inclining upwards and inwards is arranged on the press-fitting part, a shaft supporting base is arranged below the press-fitting part, and the shaft supporting base is provided with a second abutting face inclining downwards and inwards and a vertical third abutting face. By means of the structure, the positioning fixture for shaft hole drilling is convenient to operate and quick in clamping; a gap between the press-fitting part at the other end of the pressing plate and a shaft is adjusted through the eccentric cam, the shaft is clamped firmly, and therefore the positioning fixture is suitable for machining that a horizontal drilling machine drills the shaft in the horizontal direction.
Description
Technical field
The present invention relates to a kind of positioning fixture, particularly relate to a kind of positioning fixture for axle boring.
Background technology
In prior art, for the Drilling operation of axle, because axle is comparatively difficult to fix, usual employing fixture clamp shaft in advance, the form of axle clamp tool multidigit V-block conventional in prior art, the fixture of this form can only be applicable to upright drill, and drill bit processes boring from the top down, can not be applicable to the processing adopting horizontal drilling machine to hole from horizontal direction to axle.
Summary of the invention
The object of the invention is to the problem overcoming above-mentioned prior art, provide a kind of positioning fixture for axle boring, it is easy to operate, and clamping is quick, is applicable to the processing adopting horizontal drilling machine to hole from horizontal direction to axle.
The object of the invention is to be achieved through the following technical solutions:
A kind of positioning fixture for axle boring, comprise base, the centre position of described base fixedly mounts a bolt, described bolt is arranged with Compress Spring, described Compress Spring upper end abuts pressing plate, the centre of described pressing plate has guide groove, described bolt-through also extends described guide groove, the top of described bolt has Access Division, described Access Division is pressed on described guide groove, one end of described pressing plate is hinged with eccentric cam, described base is provided with the boss abutted with described eccentric cam, described eccentric cam is connected with handle, the other end of described pressing plate has the nip portion protruded out downwards, described nip portion has the first bearing surface of upwards introversion, the below of described nip portion is provided with axle supporting seat, described axle supporting seat has the second bearing surface of downward introversion and the 3rd vertical bearing surface, described first bearing surface, described second bearing surface, described 3rd bearing surface holds axle jointly.
Further, described base is provided with the drill bushing perpendicular to axle.
Further, pad is provided with between described Compress Spring and described pressing plate.
Positioning fixture for axle boring of the present invention, comprise base, the centre position of base fixedly mounts a bolt, bolt is arranged with Compress Spring, Compress Spring upper end abuts pressing plate, the centre of pressing plate has guide groove, bolt-through also extends guide groove, the top of bolt has Access Division, Access Division is pressed on guide groove, one end of pressing plate is hinged with eccentric cam, base is provided with the boss abutted with eccentric cam, eccentric cam is connected with handle, the other end of pressing plate has the nip portion protruded out downwards, nip portion has the first bearing surface of upwards introversion, the below of nip portion is provided with axle supporting seat, axle supporting seat has the second bearing surface of downward introversion and the 3rd vertical bearing surface, first bearing surface, second bearing surface, 3rd bearing surface holds axle jointly.The positioning fixture for axle boring of this structure, it is easy to operate, and clamping is quick, regulates the gap between the nip portion of the pressing plate other end and axle, firm grip axle by eccentric cam, thus is applicable to the processing that adopts horizontal drilling machine to hole from horizontal direction to axle.
