Abstract
The utility model discloses a thread processing device for an overweight or large-sized workpiece, which comprises a cutter rod body. The front end of the cutter rod body is provided with an annular cavity, a connecting shaft is matched in the annular cavity in a sliding way, the rear end of the connecting shaft is fixedly provided with a slide rod, the other end of the slide rod extends into the cutter rod body, and the slide rod is provided with a boss and is sleeved with a compression spring; and the outer sidewall of the annular cavity of the cutter rod body is provided with an axial chute, the sidewall of the connecting shaft is fixedly provided with a guide shaft extending into the chute, the front end of the connecting shaft is provided with a square hole, a quick-to-replace connecting sleeve is matched in the square hole, and the front end of the quick-to-replace connecting sleeve is fixedly provided with a cutter. The utility model can realize tapping only through rotating the spindle of a machine tool without workpiece feeding, the length of threads to be tapped is to be less than the effective rotating stroke of the roller of a tapping tool, and the tapping tool can be removed from a workpiece through reversing the spindle.
Description
Technical field
The utility model relates to overweight or large-size workpiece boring-mill work field, specifically is a kind of screw thread processing unit (plant) of overweight or large-size workpiece.
Background technology
Employed entablature in the hydraulic press, slide block (moving beam), sill and other are big. and each face all has the screw (basic size is big and the location dimension required precision is higher) that connects other parts on the heavy industry spare.Because if thread Pilot hole drawn or got out to the workpiece of overweight and appearance and size super large with screw at boring and milling machine on the planer-type milling machine, the working range of radial drilling machine can not satisfy its range of work. with the artificial tapping of pincers worker, expend bodily strength and efficient at the bottom of. and expend bodily strength.Because boring and milling machine, planer-type milling machine does not have manual feed arrangement, so design and application tapping tool.
The utility model content
The purpose of this utility model provides a kind of screw thread processing unit (plant) of overweight or large-size workpiece, machine tool chief axis only need rotate and not need the worker to advance just can finish tapping, be less than the effective travel that screw tap tool roller rotates by tapping length, the main shaft counter-rotating, screw tap just can withdraw from the workpiece.
The technical solution of the utility model is as follows:
A kind of screw thread processing unit (plant) of overweight or large-size workpiece, include the knife bar body, the rear end of knife bar body and machine tool chief axis fixed installation, front end is provided with toroidal cavity, is sliding combined with connecting axle in the toroidal cavity, and the rear end of connecting axle is set with slide bar, the other end of slide bar extend in the knife bar body, slide bar is provided with boss, is set with stage clip on the slide bar, and resist respectively in boss, knife bar body at the two ends of stage clip; The toroidal cavity lateral wall of described knife bar body has axial chute, be installed with the axis of guide that extend in the chute on the connecting axle sidewall, the front end of connecting axle is provided with square opening, is combined with quick-change connected set in the square opening, and the front end that quick change is connected is installed with cutter.
Described connecting axle rear end is set with the quick change cover, is equipped with spring between quick change cover and the connecting axle.
Be provided with ball between described quick change cover and the connecting axle.
The knife bar body was installed on the machine tool chief axis when the utility model used, screw tap is placed in the quick-change connected set, the processed thread Pilot hole of centering center, main axis rotation and work feed, the screw tap cutter is with the increase of load, the servo-actuated with the compression of stage clip, when stage clip pressure reaches certain value, screw tap begins tapping, and at this moment machine tool chief axis only need rotate and not need the worker to advance just can finish tapping, be less than the effective travel that screw tap tool roller rotates by tapping length, main shaft counter-rotating screw tap just withdraws from.
