Description
A kind of stud, nut specific complex sleeve are the specific purpose tools that is used for dismounting stud, nut.
In the prior art, have only the sleeve that is used to tighten stud or fastening nut separately, this sleeve is to adopt three ball type cam claws to hold the polished rod part of stud tightly and tighten, and screw rod is not if there is the polished rod part, this sleeve then can damage screw flight, influences its effect.The Chinese patent that retrieves " the quick tightening tool of stud " is to utilize the helix of thread lift angle greater than screw thread equivalent angle of friction (ZL89215441), make screw thread lose self-locking, during use tightening tool lower end screw thread key cover is spun on the stud, rotary handle or machine power spanner drive leading screw, make alignment pin rotation direction helicla flute lower end, leading screw lower end bulb withstands the stud upper surface, forces to drive sleeve, the rotation of screw thread key cover, thereby stud is tightened on the body fast.Another Chinese patent " stud socket wrench specially adapted for it " (ZL90220848) by sleeve body, socket cover,, clamping screw forms, and by socket cover and clamping screw stud produced pretightning force, reaches the purpose of dismounting stud.This sleeve can only be used to tight a bolt, and tightening of nut needs to change other instruments; Can only with the supporting use of hand-operated tools, can not use with the power-driven tool combination accessory.
The purpose of this utility model is at the problems referred to above, by adopting the combining structure of sleeve body, clamp mechanism and six sides cover, is achieved as follows purpose: the assembling of stud or dismounting; Stud and the nut that connects are with it joined with same set of wound packages or are dismantled; This combined sleeve can directly link to each other with manual or power-driven tool and be used to assemble the assembling-disassembling bolt nut.
The technical solution of the utility model is: it is made up of sleeve body, clamp mechanism, six sides cover (12) three parts.Sleeve body by driving shaft (1), coupling sleeve (2), spring (3), thread bush (4), carry on the back tight nut (5) and positioning sleeve (6) is formed, be drilled with pin-and-hole A and axis normal at an end garden cylinder of driving shaft (1), the center, other end is drilled with shoulder hole C; Positioning sleeve (6) inner chamber is multistage shoulder hole, one end shoulder hole C
1Put into spring (3) in the cavity that is surrounded with driving shaft (1) shoulder hole C, the other end is provided with bellmouth G, on the outer garden of positioning sleeve (6) all portion two or three holes are arranged, locking steel ball (7) places in it; Driving shaft (1) is meshed by end tooth D with positioning sleeve (6) and transmits motion, both are contained in the thread bush (4) jointly, thread bush (4) respectively with coupling sleeve (2), carry on the back tight nut (5) external screw thread and connect, driving shaft (1) connects with thread bush (4) by utilizing its shaft shoulder seam of coupling sleeve (2) B.
Clamp mechanism is made up of locking steel ball (7), the push rod (8) that has frustum F, bearing pin (9), the back-moving spring (10), the clamp (11) that are contained on the push rod (8).Clamp (11) is to be made of two or three splits, and push rod (8) and back-moving spring (10) are mounted in it, and are processed with taper surface G on the outer garden face of clamp (11) one ends
1Be complementary with the bellmouth G of positioning sleeve (6), also be processed with the groove E on band slope on the excircle of clamp (11), locking steel ball (7) falls in the groove E by positioning sleeve (6); Be provided with cam surface F at clamp (11) inner chamber
1Be complementary with the frustum F of push rod (8), bearing pin (9) passes clamp (11) and push rod (8), and it is the fulcrum of clamp (11).Six sides covers (12) connect with the end thread of positioning sleeve (6).
Effect of the present utility model is: the function that 1, will tighten stud and nut is compound, simple in structure, improves efficiency of assembling; 2, can be used for bull combination assembling, be suitable for simultaneously manually and power-driven tool; 3, can be used for the single head and the bull combination assembling of stud, reliability and durability, do not damage screw thread.
Drawing explanation to accompanying drawing:
Fig. 1 is stud, nut specific complex tube-in-tube structure figure;
Fig. 2 is the front view of clamp 11;
Fig. 3 is the vertical view of clamp 11;
Fig. 4 is the I-I cutaway view among Fig. 3.
Most preferred embodiment accompanying drawings of the present utility model.Known by Fig. 1: stud, nut specific complex sleeve are made up of sleeve body, clamp mechanism, six sides cover (12) three parts.Sleeve body by driving shaft (1), coupling sleeve (2), spring (3), thread bush (4), carry on the back tight nut (5) and positioning sleeve (6) is formed; End garden cylinder at driving shaft (1) is drilled with pin-and-hole A and axis normal, and the center, other end is drilled with shoulder hole C; Positioning sleeve (6) inner chamber is multistage shoulder hole, one end shoulder hole C
1Put into spring (3) in the cavity that is surrounded with driving shaft (1) shoulder hole C, the other end is provided with bellmouth G, and all portion has two or three holes locking steel balls (7) to place in it on the outer garden of positioning sleeve (6); Driving shaft (1) is meshed by end tooth D with positioning sleeve (6) and transmits motion, both are contained in the thread bush (4) jointly, thread bush (4) respectively with coupling sleeve (2), carry on the back tight nut (5) external screw thread and connect, driving shaft (1) connects with thread bush (4) by utilizing its shaft shoulder seam of coupling sleeve (2) B.Clamp mechanism is made up of locking steel ball (7), the push rod (8) that has frustum F, bearing pin (9), the back-moving spring (10), the clamp (11) that are enclosed within on the push rod (8); Know that by Fig. 2, Fig. 3, Fig. 4 clamp (11) is made up of two or three splits, push rod (8) and back-moving spring (10) are mounted in it, and are processed with taper surface G on the outer garden face of clamp (11) one ends
1Be complementary with the bellmouth G of positioning sleeve (6), also be processed with the groove E on band slope on the excircle of clamp (11), clamp (11) inner chamber is provided with cam surface F
1Be complementary with the frustum F of push rod (8), bearing pin (9) passes clamp (11) and push rod (8) is the fulcrum of clamp (11).Six sides covers (12) connect with the end thread of positioning sleeve (6).
The course of work of the present utility model: driving shaft (1) links to each other with manual or impact wrench, and stud is inserted in the clamp (11), moves behind push rod (8), and push rod (8) breaks away from clamp (11) cam surface F
1, move after making clamp (11) integral body, because the effect of the anterior bellmouth G of positioning sleeve (6) forces clamp (11) front aperture internal thread and bolt thread to mesh, and holds bolt tightly; On the other hand, move behind the clamp (11) make locking steel ball (7) fall in the groove E of clamp (11), clamp (11) front end can not be opened, thereby holds bolt tightly.After tightening end, only need sleeve one is with backward the whole reach of clamp (11), leave positioning sleeve (6) bellmouth G, locking steel ball (7) is climbed up the slope, and clamp (11) front end is opened, get final product release bolt, push rod (8) snaps in the cam surface F of clamp (11) by back-moving spring (10) with it
1In, make clamp (11) keep open configuration.After adding coupled on the stud of having tightened, because the stud overhang shortens, clamp mechanism can not act on, and the six sides covers (12) that are positioned at barrel forward end promptly can be used for assembling nut.If after removing six sides covers (12), also can be used for the single head and the bull combination assembling of stud separately.
