Abstract
The utility model relates to a stud quick tightening tool, primarily due to the fact that the angle of spiral of the screw thread is greater than the equivalent friction angle of the screw thread, and the screw thread lose self locking. The screw thread key mat arranged on the lower end of the stud quick tightening tool is tightened and then is screwed on the stud when the stud quick tightening tool is used, a rotating handle or a mechanical power spanner drive a screw rod to make the locating pin screw the lower end of the spiral groove, a ball head arranged on the lower end of the screw rod withstands the upper end surface of the stud to compulsorily drive the sleeve, screw thread and key mat to rotate, and therefore, rapidly tightens the stud to the body. When the stud quick tightening tool is dismounted, screwing in external force to release the connection of the sleeve and the screw rod to make the screw thread lose self-locking ability, and the stud quick tightening tool can be dismounted by reversely rotating the handle, enhancing efficiency and ensuring quality.
Description
The utility model relates to a kind of tightening tool, particularly a kind of quick tightening tool of stud that is used for.
The body of machinery equipment connects; often having a lot of studs is screwed into; being screwed into of stud is that tube pincers or spanner are tightened at present, damages bolt light rod easily with pipe wrench, influences quality; if tighten with spanner; because of the screw thread self-locking, occur easily skidding, easily stud is unloaded from body when unloading tightening tool; and time-consuming taking a lot of work, be difficult for ensuring the quality of products.
The purpose of this utility model is: overcome above-mentioned weak point of the prior art, and provide a kind of stud quick tightening tool.
Design of the present utility model is: the special character of the quick tightening tool of stud is that the helix of thread lift angle is greater than the screw thread equivalent friction angle, make screw thread lose self-locking, it is by the handle that wears spherical nut (1) in the handle hole (7) that is contained in leading screw upper end, and a sleeve (2), a leading screw (3), an alignment pin (4), serial screw thread key cover (5) are formed.
The utility model is that sleeve (2) upper end connects with leading screw (3), it connects screw thread for strengthening the bull trapezoidal thread of the angle of spiral, rotation direction is consistent with the stud that is screwed into, have the helicla flute consistent with angle of spiral rotation direction (8) on the symmetric position of sleeve (2), the lower end has positioning spline (9).
The utility model is to be furnished with on the leading screw (3) the corresponding to alignment pin of helicla flute (8) (4) with sleeve (2), limit the slewing area of leading screw (3) in sleeve (2), alignment pin (4) can only be moved in helicla flute (8), leading screw (3) upper end is provided with handle hole (7), and the square spanner hole (6) of mechanical work is left at the top.
The utility model is the serial screw thread key cover (5) that is adapted to tighten various bolts that is equipped with, and the outer end symmetric position is provided with convex key (10), is complementary with sleeve (2) lower end positioning spline (9).
Fig. 1 is the front view of a kind of concrete structure of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 1.
Fig. 4 is that the C of Fig. 1 is to view.
Fig. 5 is the B-B cutaway view of Fig. 2.
With reference to Fig. 1: handle (1), a sleeve (2), a leading screw (3), an alignment pin (4), screw thread key cover (5), a square spanner hole (6) that wears spherical nut.
With reference to Fig. 2: handle hole (7), helicla flute (8), positioning spline (9).
With reference to Fig. 4: convex key (10).
The enforcement of the quick tightening tool of stud: in use tightening tool lower end screw thread key cover (5) is spun on the stud, rotary handle (1) or machine power spanner drive leading screw (3), make alignment pin (4) rotation direction helicla flute (8) lower end, at this moment leading screw (3) lower end bulb withstands the stud upper surface, force to drive sleeve (2), screw thread key cover (5) rotation, thereby stud is tightened on the body fast.When unloading instrument, be screwed into after external force removes, the connection screw thread of sleeve (2) and leading screw (3) loses self-lock ability, needs only backward rotation handle (1), just can easily unload instrument from stud fast.
The utility model has following advantage compared with prior art:
1, guarantees screw thread polished rod, the end face not damaged of stud, improve assembly precision.
2, use reliably, simple and convenient, can not drive stud at all and unload from body, can not skid yet.
3, improved operating efficiency, manually improved 3~5 times of work efficiency than general purpose tool, if operate with machine power, work efficiency will be higher.
4, compact conformation, light, volume is little, implement than being easier to
Claims (4)
1, a kind of quick tightening tool of stud with handle and sleeve and leading screw rotational structure, it is characterized in that the helix of thread lift angle greater than the screw thread equivalent friction angle, it is made up of handle (1), a sleeve (2), a leading screw (3), an alignment pin (4), a serial screw thread key cover (5) that wears spherical nut.
2, the quick tightening tool of stud according to claim 1, it is characterized in that sleeve (2) upper end connects with leading screw (3), it connects screw thread for strengthening the bull trapezoidal thread of the angle of spiral, rotation direction is consistent with the stud that is screwed into, have the helicla flute consistent with angle of spiral rotation direction (8) on the symmetric position of sleeve (2), the lower end has positioning spline (9).
3, the quick tightening tool of stud according to claim 1, it is characterized in that being furnished with on the leading screw (3) the corresponding to alignment pin of helicla flute (8) (4) with sleeve (2), the upper end is provided with handle hole (7), and the square spanner hole (6) of mechanical work is left at the top.
4, the quick tightening tool of stud according to claim 1 is characterized in that serial screw thread key cover (5) outer end symmetric position is provided with convex key (10), is complementary with sleeve (2) lower end positioning spline (9).
