Abstract
The utility model relates to internal thread processing equipment, in particular to a movable device for clamping screw taps quickly and automatically during work of a tapping machine. The movable device for clamping the screw taps quickly and automatically during work of the tapping machine comprises a screw tap outer sleeve, a nut shield, a screw tap inner sleeve and a spring, wherein the screw tap inner sleeve is mounted in the screw tap outer sleeve, the nut shield is mounted at the left end of the screw tap outer sleeve, the spring is mounted at the right end of the screw tap inner sleeve, a tool withdrawal groove is formed in the outer side of the left end of the screw tap outer sleeve, a tapered convex column is mounted on the circumference of the screw tap outer sleeve and located on the right side of the tool withdrawal groove; a slope surface is arranged on the right side of the tapered convex column, and a thread is mounted on the inner side of the right end of the nut shield. The movable device has the benefits of simple structure, convenience in use, safety and reliability; a hop phenomenon is avoided for six screw taps during high speed rotation of a spindle; after long-term use, when the device is used for tapping, a thread form is relatively full and round, a tolerance meets the requirement, and the screw taps are not damaged easily, so that the manufacturing cost is reduced greatly, and the product quality is improved.
Description
Technical field
The utility model relates to a kind of internal thread machining equipment, particularly the head of fast automatic accurate clamping screw tap in a kind of tapping machine work.
Background technology
At present, in tapping machine, have and need quick-clamping screw tap, only to do excessive arc structure at the opening of screw tap clamp contact, object is to facilitate screw tap to snap in, but owing to cannot moving axially between fixture and main shaft, unsatisfactory in using so actual, many times can not block, or card has been gone up and has come off.
Utility model content
The utility model, in order to make up the defect of prior art, provides a kind of simple in structure, the head of fast automatic accurate clamping screw tap in the convenient tapping machine work of using.
The utility model is achieved by the following technical solution:
The head of fast automatic accurate clamping screw tap in a kind of tapping machine work, comprise screw tap overcoat, nut door, screw tap inner sleeve and spring, in described screw tap overcoat, screw tap inner sleeve is housed, screw tap overcoat left end is equipped with nut door, described screw tap inner sleeve right-hand member is equipped with spring, escape is equipped with in described screw tap overcoat left end outside, screw tap overcoat periphery is equipped with taper projection, taper projection is positioned at escape right side, taper projection right side is slope, screw thread is equipped with in described nut door right-hand member inner side, and nut door and screw tap overcoat are threaded connection.
Further, on described screw tap outer casing inner wall, boss is housed, its boss becomes all distributions such as 60 ° of angles around the screw tap overcoat center of circle.
Further, described screw tap inner sleeve center is cavity, and groove is equipped with in its left side, on groove inwall, boss is housed, and boss becomes all distributions such as 60 ° of angles around the screw tap inner sleeve center of circle.
The beneficial effects of the utility model are: simple in structure, easy to use, safe and reliable, when main shaft is during at High Rotation Speed, six screw taps do not have jumping phenomena to occur, through long-time use, find, with this, install tapping, form of thread can be fuller, tolerance meets the requirements, and screw tap do not allow perishablely, greatly reduce production cost, improved product quality.
