The utility model belongs to field of mechanical technique, and in particular to a kind of bolt repairs threading tool, and drilling machine is supporting makes With the mantle fiber reparation realized to reusable bolt.
Background technology
Coal mining enterprise can remove the bolt of substantial amounts of different model specification because of withdrawing for working face, these bolt bodies compared with It is good, but because the corrosion and lodging of screw thread can not directly reuse, it is necessary to old bolt screw thread is carried out mantle fiber reparation so as to up to To use requirement, existing conventional mantle fiber method is, manually using screw die, and mantle fiber reparation is carried out to old bolt, and efficiency is low, work Intensity is big.
The content of the invention
In order to solve the problems of the prior art, bolt mantle fiber reparation effect can be improved the utility model proposes one kind Rate, ensures that the bolt of repairing quality repairs threading tool.
In order to realize the above object the technical scheme that is used of the utility model for:Including screw die frock and for clamping The fixture of bolt, the screw die frock is fixedly connected with drill press spindle drilling attachment, the fixture and the platform of drill press spindle lower end Pincers are fixedly connected, and the screw die frock includes hollow sleeve, and sleeve one end is fixedly connected with drill press spindle drilling attachment, the other end It is fixedly installed screw die.
The sleeve is fixedly connected by drill holder with drill press spindle drilling attachment, and big end and sleeve one end of drill holder are consolidated Fixed connection, the small end of drill holder is fixedly connected with drill press spindle drilling attachment.
The sleeve and drill holder are coaxially disposed with drill press spindle.
The observation window that state is repaired for observing bolt is offered on the side wall of the sleeve.
The sleeve is set to step-like, and the big end of sleeve is enclosed on the screw die, and sleeve and screw die interference fits.
Tapped through hole is offered on the big side wall of the sleeve, the side wall of screw die offers tapped blind hole, and sleeve passes through Tapped through hole described in jackscrew precession is fixedly connected with screw die with tapped blind hole.
The screw die is to be evenly arranged with five cutting faces on circular screw die, screw die.
The fixture includes offering several semicircle slotted eyes on two clamping plates being engaged, clamping plate.
Compared with prior art, screw die frock is fixedly connected by the utility model with drill press spindle drilling attachment, for pressing from both sides The fixture for holding bolt is fixedly connected with the bench vice of drill press spindle lower end, and bolt is carried out using drill press spindle drive sleeve and screw die Repair, by being used on drilling machine, the theory of mechanics of the workpiece center of circle and adjustable main rotating speed automatically determined with reference to radial drilling machine, The mantle fiber reparation to bolt is realized, bolt remediation efficiency and quality is substantially increased, the bolt after reparation can be continued up to and used It is required that, it is that accessory cost has been saved in the production of enterprise.
Further, sleeve is fixedly connected by drill holder with drill press spindle drilling attachment, can make whole device and main shaft It is more firm that drilling attachment is connected, and improves stability of the present utility model.
Further, observation window is offered on the side wall of sleeve, is easy to observation bolt to repair state, be easy to adjustment in time to repair Multiple operation, it is to avoid the damage to bolt.
Further, sleeve is fixedly connected with screw die by jackscrew, and make that sleeve and screw die fix is more firm.
Further, fixture includes offering several semicircle slotted eyes on two clamping plates being engaged, clamping plate, two folders Plate, which is engaged, to be made to be bolted in slotted eye, and fixture can once install plurality of bolts additional and carry out mantle fiber reparation, improves remediation efficiency.
