Abstract
The invention discloses a screwing tool for a round thin-head screw. The screwing tool comprises an elastic sleeve threaded rod, a lock sleeve, a spring, a gasket, a locking wheel, an anti-turning wheel and an anti-turning pin, wherein the head part of the thin-head screw is tightly clamped by adopting an elastic sleeve mode, and a screw thread and a conical surface force-amplifier are adopted. Therefore, the operation is not only convenient, time-saving and force-saving, but the screwing force of the screw also can meet the design requirements.
Description
Technical field
The present invention relates to a kind of screw tightening device, the tightening tool of especially round thin screw.
Background technology
Along with industrial development, some industrial products can be because design need to be assembled thin screw of a kind of circle, because having square toes or fluting etc., thin screw head of circle be not convenient to the structure of assembling, during assembling, can only first by hand screw be screwed into by dress body, adopt again the jaw secondary of the instruments such as vice to tighten, during assembling, not only waste time and energy, and screwing force is not easy to reach designing requirement.
Summary of the invention
Object of the present invention is just to provide thin screw tightening device of a kind of circle, and thin the screw of circle that solves prior art existence is not easy to the problem of assembling.
Technical scheme of the present invention is: thin screw tightening device of a kind of circle, comprises resilient sleeve screw rod (2), lock sleeve (3), spring (4), packing ring (5), locking wheel (6), spline wheel (7) and spline pin (8).Circle thin screw (1) head is arranged in the plum blossom hole of resilient sleeve screw rod (2) end.Spring (4) is assemblied on resilient sleeve screw rod (2), resilient sleeve screw rod (2) is arranged in lock sleeve (3) hole, resilient sleeve screw rod (2) male cone (strobilus masculinus) contacts with lock sleeve (3) inner conical surface, and resilient sleeve screw rod (2) conical surface is provided with equally distributed notching construction.Resilient sleeve screw rod (2) other end is provided with external screw thread, and with the screw-internal thread fit of locking wheel (6), packing ring (5) is positioned between lock sleeve (3) and locking wheel (6).Spline wheel (7) is assemblied in resilient sleeve screw rod (2) end, is to be threaded with resilient sleeve screw rod (2).Spline pin (8) is assemblied on spline wheel (7) and resilient sleeve screw rod (2).
The present invention has the following advantages: the present invention adopts resilient sleeve mode to clamp thin screw head of circle, and has adopted screw thread, conical surface force-increasing mechanism, not only easy to operate, time saving and energy saving, and can meet screw-driving power and reach designing requirement.

The specific embodiment
Referring to Fig. 1 to Fig. 3, the present invention includes resilient sleeve screw rod (2), lock sleeve (3), spring (4), packing ring (5), locking wheel (6), spline wheel (7) and spline pin (8).Circle thin screw (1) head is arranged in the plum blossom hole of resilient sleeve screw rod (2) end.Spring (4) is assemblied on resilient sleeve screw rod (2), resilient sleeve screw rod (2) is arranged in lock sleeve (3) hole, resilient sleeve screw rod (2) male cone (strobilus masculinus) contacts with lock sleeve (3) inner conical surface, and resilient sleeve screw rod (2) conical surface is provided with equally distributed notching construction.Resilient sleeve screw rod (2) other end is provided with external screw thread, and with the screw-internal thread fit of locking wheel (6), packing ring (5) is positioned between lock sleeve (3) and locking wheel (6).Spline wheel (7) is assemblied in resilient sleeve screw rod (2) end, is to be threaded with resilient sleeve screw rod (2).Spline pin (8) is assemblied on spline wheel (7) and resilient sleeve screw rod (2).
The course of work: will justify thin screw (1) head and be loaded in the plum blossom hole of resilient sleeve screw rod (2) end, one of operator holds tight spline wheel (7), keep lock sleeve (3) end face and filled the parallel of body plane, another hand is tightened locking wheel (6), drive thin screw of circle (1) to rotate together, screw in and filled body until tighten and reach requirement.After screw-driving, counter-rotation locking wheel (6), locking wheel (6) plane departs from packing ring (5) plane, under spring (4) power effect, resilient sleeve screw rod (2) unclamps circle thin screw (1) head, can unload tightening tool.
The invention solves thin screw of circle in prior art and be not easy to the problem of assembling.
