Abstract
The invention provides a quick screwing sleeve of a double-end stud. The quick screwing sleeve comprises an inner sleeve body (2) serving as an elastic chuck, and an outer sleeve body (3) sleeved outside the inner sleeve body (2) and serving as a locking sleeve. The outer side of the front end of the outer sleeve body (3) is in threaded connection with a nut (1), the outer side of the rear end of the outer sleeve body (3) is in threaded connection with a connection sleeve (5), and four Achimedean spirals are uniformly distributed in the radial section of the surface where the inner sleeve body (2) is contacted with the outer sleeve body (3). The quick screwing sleeve can be installed on a pneumatic (electric) wrench, the wrench is rotated, the double-end stud to be screwed can be screwed, then the double-end stud is driven to be screwed into a screw hole in a machine body, the stud is automatically locked when encountering resistance, and the larger the resistance is, the larger the locking force is, and the locking force in increased along with the resistance until the stud is screwed in the screw hole in the machine body. Then the wrench is reversely rotated, the stud can be released, reverse friction torque does not exist, and the stud can be easily screwed out.
Description
?
Technical field
The present invention is a kind of as the machine tool that tightens fast, specifically is that a kind of studs tightens sleeve fast.
Background technology
All the time, studs tightens at machine, generally the method that all adopts double nut to screw.Need to use hand-operated tools, time-consuming, effort.And existing studs tightening tool generally has the structure of more complicated, manufacturing cost height not only, and also stability in use is not good enough.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of studs to tighten sleeve fast, and the process of tightening can the auto lock double-screw bolt, and the more big coupling mechanism force of resistance is more big, and the counter-rotating sleeve is the instant-free double-screw bolt then, does not have reverse moment of friction, can briskly withdraw from.To improve the efficient that studs tightens work, reduce manual operations, and have fairly simple, compact structure.
Technical scheme of the present invention is as follows:
A kind of studs tightens sleeve fast, it is characterized in that: comprise the interior cover as collet, and in being enclosed within outside the cover and as the overcoat of lock sleeve, the nut that has been threaded outside the overcoat front end, adapter sleeve has been threaded outside the overcoat rear end; Contacted surface between interior cover and the overcoat is equally distributed four Archimedes spirals in radial section.
The first half of cover is retained part in described, the outside of this part is distributed with the curved surface that four Archimedes spirals constitute, inside is regular screw threads, and the latter half of interior cover is a thin walled cylinder body, offers some axial port grooves on interior cover circumference evenly distributedly;
Also comprise the lining between the thin walled cylinder body that is in overcoat and interior cover.
Interior cover is elastic part, and material therefor is 55Si2Mn, and the hardness after the quenching is HRC50-55.
The invention has the beneficial effects as follows: cover is a collet in of the present invention, and it is can radial contraction and the elastic part of expansion.Contacted surface between the inside and outside cover is equally distributed four Archimedes spirals in radial section.When overcoat rotated with respect to interior cover counter-clockwise direction, interior cover was subjected to the extruding of overcoat, inwardly shrank and locked double-screw bolt; When overcoat rotated with respect to interior cover clockwise direction, overcoat loosened, and interior cover leans on the elasticity distending of self and discharges double-screw bolt.
Studs of the present invention can be tightened fast sleeve is installed on pneumatic (electronic) spanner, rotating spanner, can screw in studs to be tightened, driving studs then screws in the machine body screw, back auto lock double-screw bolt meets obstructions, and the more big coupling mechanism force of resistance is more big, up to double-screw bolt is tightened in the machine body screw; Spanner is played counter-rotating then, and sleeve is the instant-free double-screw bolt then, does not have reverse moment of friction, brisk withdrawing from, and do not weaken the stationary state that has tightened double-screw bolt at all.Make the work that tightens double-screw bolt become light.Compare with hand-operated tools, can increase work efficiency more than 6 times.
The present invention also has compact conformation, simple, the outstanding feature of stable performance.
Description of drawings
Fig. 1 is structure of the present invention and principle schematic.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the planform schematic diagram of cover in the present invention.
Fig. 4 is the end view of cover in the present invention.
The specific embodiment
Further specify the present invention below in conjunction with drawings and Examples.
Referring to Fig. 1, Fig. 2, the present invention includes the interior cover 2 as collet, in being enclosed within outside the cover 2 and as the overcoat 3 of lock sleeve,
The nut 1 that has been threaded outside overcoat 3 front ends, adapter sleeve 5 has been threaded outside overcoat 3 rear ends.Nut 1 and adapter sleeve 5 play internal cover 2 and overcoat 3 axial location effects, and adapter sleeve 5 also plays a part transferring power.During use spanner is connected with adapter sleeve 5, overlaps in 2 in insert the outer end of studs.Contacted surface between interior cover 2 and the overcoat 3 is equally distributed four Archimedes spirals in radial section.That is to say that kinematic pair-higher pair that interior cover 2 and overcoat are 3 is four identical Archimedes spirals in radial section.
As shown in Figure 3, Figure 4, the first half of interior cover 2 of the present invention is retained part, and the outside of this part is distributed with the curved surface that four Archimedes spirals constitute, and inside is regular screw threads (associated studs); In cover 2 latter half be a thin walled cylinder body, both position points that cooperates with overcoat 3 as interior cover 2, as the adaptation part strain takes place repeatedly again and have a necessary structure of fatigue performance.On interior cover 2 circumference, offer four axial port groove 2-1 evenly distributedly, form retaining part and produce the necessary structure of resilient radial displacement.The collet material therefor is 55Si2Mn, and the hardness after the quenching is HRC50-55.Make part have good wearability and high fatigue strength.
Faying face between interior cover 2 and the overcoat 3 is formed by Archimedes spiral.When overcoat 3 was rotated counterclockwise an angle (as 5 °) with respect to interior cover 2, a displacement radially took place in interior cover 2 under the effect of overcoat 3.So interior cover 2 radial dimensions diminish, thereby clamp double-screw bolt.
The present invention also comprises the lining 4 that is between interior cover 2 and the overcoat 3, and specifically, lining 4 is between the thin walled cylinder body of overcoat 3 and interior cover 2.The effect of lining 4 is structures of adjusting interior cover 2 and 3 two parts of overcoat, and makes it have favorable manufacturability (being easy to processing and fabricating).
The parameter of above-mentioned Archimedes spiral is done rational design, and the clamping force during work just can produce enough frictional force, and then produces enough moments of torsion to tighten double-screw bolt.And when overcoat 3 clockwise rotated with respect to interior cover 2, overcoat can slide interior putting lightly, and double-screw bolt was not produced opposing torque, thereby kept the existing tightness that goes up of double-screw bolt.
