Technical Field
The invention mainly relates to the field of tapping tools, in particular to a tool for machining a bolt die by a lathe tail lathe.
Background
The threading die is a tool for processing or correcting external threads, when the threading die frame is held by hands to process the external threads, a processed workpiece is slow, the processed workpiece can only be used for processing the bolt of M12 to the maximum extent, the processed bolt cannot meet the quality requirement, the number of waste products is large, and potential safety hazards are easy to occur. At present, companies design tools aiming at the processing of external threads, so that the processing of the external threads is suitable for mechanized operation.
The patent number is CN 202506915U's a quick chasing bar of center lathe, discloses a section and utilizes lathe blade holder auto-feed function to realize the frock of bolt processing, and this frock is simple easily operated, but need rely on the auto-feed function of lathe blade holder, need carry out the tool setting operation before the use, and need the blade holder to carry out steady feeding, and the operation is comparatively troublesome.
Disclosure of Invention
In order to solve the defects of the prior art, the invention provides the bolt threading die tool for machining the rear tail lathe of the lathe, which does not rely on a feed tool apron of the lathe any more, does not need tool setting operation before machining, can realize the machining of the external thread only by controlling the positive and negative rotation of a main shaft of the lathe, and has simple operation and higher efficiency.
In order to achieve the purpose, the invention is realized by the following technical scheme:
the utility model provides a tail lathe processing bolt die frock behind lathe, includes die, die seat, sleeve and connecting rod, the die seat includes the fixed head of front end and the slide bar of tail end, fixed head tip can dismantle fixed connection with the die, slide bar and sleeve sliding connection, connecting rod and sleeve fixed connection.
The end part of the fixing head is provided with a die slot, the die is matched with the die slot, the side wall of the fixing head is provided with a fastening screw hole communicated with the die slot, and a fastening bolt is arranged in the fastening screw hole.
The slide bar is a non-circular bar, and the cross section of the slide bar is consistent with the cross section of the inner cavity of the sleeve.
The slide bar both sides all set up the draw runner, set up in the sleeve with draw runner matched with slide.
The side face of the sleeve is provided with a long hole along the axis direction, the tail end of the sliding rod is provided with a positioning screw hole, a positioning bolt is arranged in the positioning screw hole, and the positioning bolt is connected with the long hole in a sliding mode.
The connecting rod is a taper shank connecting rod.
The die handle is characterized in that a liquid guide groove is formed in the side face of the die handle seat, a liquid inlet corresponding to the liquid guide groove is formed in one side of the front end of the sleeve, and when the die handle is used, the liquid guide groove and the liquid inlet face upward.
The liquid inlet is provided with a flow guide nozzle.
Compared with the prior art, the invention has the beneficial effects that:
the threading die is detachably fixed on the threading die seat, the threading die seat can slide in the sleeve through the slide rod, and the whole device is fixed on a rear tailstock of a lathe through the connecting rod to replace the position of an original center. The distance between tailstock and the chuck after adjusting utilizes the chuck to carry out the clamping to the column part, will back tailstock push forward slightly, makes the part tip card at the die terminal surface, makes the chuck corotation carry out the processing of part external screw thread, and along with deepening of external screw thread processing, the die seat rolls off gradually in the sleeve to the screw thread processing of the part is more deepened to the cooperation part. After the external thread is machined, the chuck is rotated reversely to complete the withdrawing of the part in the die, and the die seat is gradually recovered into the sleeve.
