Abstract
The utility model discloses an internal inserting sleeve for tightening round nut, which comprises a fixing sleeve and a pressing piece. The fixing sleeve comprises a large end part and a small end part. An up-down through hole is arranged in the fixing sleeve center. A groove, facing the position of a round nut clamp, is arranged on the external wall of the large end part. The pressing piece is inlaid in the groove and extends to the through hole along the central shaft direction of the through. The utility model has the advantages of a simple structure, high efficiency, a long service life and convenient connection. The utility model can prevent tool damage due to too much tightening force to fix a screw nut. The utility model can be widely used in machinery manufacture industry, especially the motor manufacture industry.
Description
Technical field
The utility model relates to a kind of sleeve of fastening nut, relates in particular to a kind of internally-inlaid sleeve of tightening round nut.
Background technology
In machinery manufacturing industry, particularly engine building, some position on the engine requires component location guide nut, and screw-down torque requires greatlyyer, does not all have a kind of durable in use, the instrument that can tighten round nut fast all the time.At present the tightening tool of the end face pressing block type that adopts even twist at leisure by hand, also can cause the briquetting fracture of tightening tool to be scrapped, and its service life, weak point very if use pneumatic or electric wrench drives tightening tool, ruptured with regard to the easier briquetting that causes.If adopt and to beat drift and assemble by hand, though the service life of drift is long, same exist effort, operating efficiency low, can't tighten to problem such as regulation moment.Because no proper tools, the screw-down torque of round nut also can't be checked.
Summary of the invention
The technical problems to be solved in the utility model is the defective that overcomes prior art, provide a kind of can prevent that screwing force is excessive and cause that instrument is fragile, high efficiency, long service life, the convenient internally-inlaid sleeve of tightening round nut that connects.
For solving the problems of the technologies described above, the utility model provides a kind of internally-inlaid sleeve of tightening round nut, comprise fixed cover and briquetting, described fixed cover comprises a big end parts and a small end part, have the through hole of up/down perforation in described fixed cover central authorities, offer the corresponding groove in bayonet socket position with round nut on the end wall of the outside of described big end parts, described briquetting is spliced in described groove, and extends in the described through hole towards the central axis direction of described through hole.
Wherein, described through hole comprises the round nut resigning hole that is opened in described big end parts, is opened in the square opening of described small end part, and is opened in the spindle nose resigning hole between described round nut resigning hole and the square opening.Preferably, described groove is provided with 4.
As a kind of improvement of the present utility model, the radial depth of described groove is greater than the cylindrical of the big end parts of described fixed cover and the thickness between round nut resigning hole hole wall, and the axial depth of groove is greater than the axial depth of fixed cover round nut resigning hole.
As another kind of improvement the of the present utility model, the axial depth of described round nut resigning hole is less than round nut thickness.The diameter of described spindle nose resigning hole is greater than the screwhole diameter of round nut.
Owing to adopt above-mentioned technical scheme, the utlity model has following beneficial effect:
1, simple in structure, high efficiency, long service life;
But prevent to cause instrument fragile during 2 component location guide nuts because of screwing force is excessive;
3, the convenient connection.
Description of drawings
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-fixed cover; The 2-briquetting; The 3-round nut; The big end parts of 4-fixed cover;
The small end part of 5-fixed cover; 6-round nut resigning hole; 7-spindle nose resigning hole; The 8-square opening.
The specific embodiment
As depicted in figs. 1 and 2, the utility model is tightened the internally-inlaid sleeve of round nut, comprise fixed cover 1 and briquetting 2, this fixed cover 1 comprises a big end parts 4 and a small end part 5, have the through hole of up/down perforation in the central authorities of fixed cover 1, aforesaid through hole comprises the round nut resigning hole 6 that is opened in big end parts 4, is opened in the square opening 8 of small end part 5, and is opened in the spindle nose resigning hole 7 between round nut resigning hole 6 and the square opening 8.Offer the corresponding groove in bayonet socket position with round nut 3 on the end wall of the outside of aforesaid big end parts 4, briquetting 2 is spliced in this groove, and extends in this round nut resigning hole 6 towards the central axis direction of round nut resigning hole 6.Promptly as Fig. 2, briquetting 2 one ends protrude certain-length L2 towards fixed cover round nut resigning hole 6, and the other end of briquetting does not protrude the cylindrical of fixed cover large end face; Preferably, groove offers 4 corresponding to the bayonet socket of round nut.
The radial depth of groove (being H3) is greater than the cylindrical of the big end parts of fixed cover and the thickness between round nut resigning hole 6 hole walls, and the axial depth of groove (being H2) is greater than the axial depth (being H1) of round nut resigning hole 6.
The axial depth of round nut resigning hole 6 (being H1) is less than round nut 3 thickness (being H4).The diameter of spindle nose resigning hole 7 is greater than the screwhole diameter of round nut 3, and its degree of depth is greater than the spindle nose length of the round nut that protrudes.
In manufacturing process, must not weld in the round nut resigning hole 6, the weld seam of end face also must not be welded in the round nut resigning hole 6, and weld seam must not protrude the large end face of fixed cover; The outer side weld of fixed cover large end face and briquetting can adopt the groove welding, and postwelding processing is smooth.So just guaranteed that sleeve can reach the result of use of expection.
In use, round nut resigning hole 6 is set on the round nut 3, and rotational sleeve makes briquetting 2 stick into the bayonet socket of round nut 3 slightly, the square opening 8 at fixed cover small end part 5 places connects with instruments such as pneumatic impact wrench, torque spanneres, can easily and quickly round nut 3 be tightened, and dodge the spindle nose that protrudes round nut 3 by spindle nose resigning hole 7, after the square opening 8 at fixed cover small end part 5 places connects instrumentations such as going up the dial plate torque spanner, also can be used to check the screw-down torque of round nut 3.
The utility model for the component location guide nut provide a kind of can manual pneumatic or electronic tightening tool, it is simple, convenient, quick, durable, the moment after tightening can satisfy the matching requirements of round nut fully; Behind the instrumentation such as dial plate torque spanner, also can be used to check the screw-down torque of round nut in the connection.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
