Technical field
The utility model relates to a kind of Hooks coupling universal coupling integrated type jaw, is one of core part in the cross universal couplings such as SWC type.
Background technique
Integrated type jaw, as the strength member in cross universal coupling, should meet the requirement that certain assembly relation requires, himself intensity meets carrying again.Existing its shortcoming of integrated type jaw is: 1, each of jaw inner chamber adopts multiple plane to piece together connection mostly, thus reduce effective entity of bottom, the intensity of jaw is caused to decrease, jaw easily ruptures, due to the seamed edge of the junction generation that plane is pieced together, be also unfavorable for cast shaping process requirement; 2, because the cylindrical hole on arm is imperfect cylindrical hole, be unfavorable for machining, the non-full circle in cross section of size deviation, cylindrical hole can be produced when machining because of cutter relieving, thus easily occur when loading cross assembly Sealing to be cut off, assembles the problems such as difficulty.So how to make integrated type jaw obtain under the prerequisite meeting the physical dimensions such as inclination angle assembling technology difficulty that maximum strength takes into account production requires it is the difficult point of design integrated type jaw structure simultaneously.
Summary of the invention
Problem to be solved in the utility model be to provide a kind of shape and structure rationally, processing and assembling time convenient, the Hooks coupling universal coupling integrated type jaw that improves bulk life time.Meanwhile, this novel Hooks coupling universal coupling integrated type jaw intensity is high, and it is when assembled in pairs, and top and the inner chamber bottom of arm exist certain gap, to avoid and interferes and the entity of inner chamber maximized and meets the requirement at certain inclination angle.
This Universal coupling integrated type jaw, a pair arm about gyration center line symmetry that it comprises base portion, is extended by base portion, wherein, the middle part of each arm is provided with step hole, step hole comprises the D1 hole in outer portion and the D2 hole in inner chamber, the diameter in D2 hole is slightly larger than D1 hole, and the outside of D1 has an angle to be the chamfering of β.Wherein, D1 hole is cylindrical hole, and D2 hole is incomplete cylindricality step hole.
From above, step hole in the symmetric arms of this Novel integral jaw is made up of three sector holes, conical hole, cylindrical hole, cylindricality step hole is followed successively by from periphery to gyration center, wherein, the diameter in the D2 hole of increase, slightly larger than D1, can not produce size deviation when machining like this, namely the cross section of D1 cylindrical hole is full circle, in addition the leading role of taper hole, make this Novel integral jaw load cross assembly time easy to assembly, Sealing can not be cut off.Therefore, this Novel integral jaw shape and structure is reasonable, reduces the difficulty in machining accuracy control and in assembly process.

Embodiment
From Fig. 1, Fig. 4, this Novel integral jaw external frame is cylindroid, it has with the base portion 1 of outer type and a pair arm 2 about gyration center 3 symmetry extending of base portion 1 thus, and the top place of arm 2 cylindrical is part pyramid like configuration, arm is designed with cylinder hole structure simultaneously.
Wherein, the middle part of each arm 2 is provided with step hole 4, and step hole 4 comprises the D1 hole in outer portion and the D2 hole in inner chamber, and the diameter in D2 hole is slightly larger than D1 hole, and the outside of D1 has an angle to be the chamfering of β.Wherein, D1 hole is cylindrical hole, and D2 hole is incomplete cylindricality step hole.
From above, step hole in the symmetric arms of this Novel integral jaw is made up of three sector holes, conical hole, cylindrical hole, cylindricality step hole is followed successively by from periphery to gyration center, wherein, the diameter in the D2 hole of increase, slightly larger than D1, can not produce size deviation when machining like this, namely the cross section of D1 cylindrical hole is full circle, in addition the leading role of taper hole, make this Novel integral jaw load cross assembly time easy to assembly, Sealing can not be cut off.Therefore, this Novel integral jaw shape and structure is reasonable, reduces the difficulty in machining accuracy control and in assembly process.
From Fig. 1, Fig. 5, in jaw, the inner chamber 7 of each arm 2 is curved surface, and curved surface comprises upper curved surface, lower curved face and fillet surface 13; Wherein, upper curved surface and lower curved face adapt, and namely the shape of top and the bottom curved surface is identical, and lower curved face is formed after being biased certain value by upper curved surface, adopts fillet surface 13 to be connected between the curved surface of top and the bottom, thus inner chamber forms an entirety and continuous print curved surface.Namely the inner chamber curved surface 7 of integral is overall, a continuous print fitting surface, and region between top to the bottom being in symmetric arms 2 is also symmetrical about center line 3;
Inner chamber due to this Novel integral jaw is the many surface fittings of continuous print, can increase effective entity of bottom, the intensity of jaw be increased, not easy-rupturing, and be conducive to cast shaping process requirement; The inner chamber curved surface on cylindrical hole center line top and the inner chamber curved surface of bottom have certain complementary relationship simultaneously, to ensure that it is when assembled in pairs, there is certain gap in top and the inner chamber bottom of arm, to avoid and interfere and make the entity of inner chamber maximize and meet the requirement (wherein, θ to refer to after the assembling of two jaws pendulum angle along the circumferential direction) of certain inclination angle theta.As shown in Figure 3, at a pair novel integral be after the composition of relations of θ by inclination angle, the upper curved surface of an integral inner chamber curved surface 7 and the lower curved face of another integral inner chamber curved surface 7 adapt and leave certain interval, to avoid interference, namely the lower curved face of inner chamber curved surface 7 is formed after its upper curved surface is biased certain value, and this continuous print fitting surface is more conducive to shaping technological requirement.
From Fig. 2, Fig. 3, as this novel a kind of improved procedure, the conical surface 5 of to be cone angle be in the outside on each arm 2 top α, the gyration center line of this conical surface overlaps with center line 3, and this conical surface 5 and the excircle configuration of arm 2 pass through mutually and end in line 6 place.Wherein, the circular cone apex angle α of arm 2 becomes certain proportionate relationship with inclination angle theta, and usual cone angle α becomes certain multiple relation with jaw limit inclination angle, after assembling, does not interfere under certain inclination angle theta to prevent paired jaw.The conical surface 5 on each arm 2 top can meet any position of jaw when there being inclination angle and can not exceed the swing diameter of jaw itself, can not interfere phenomenon like this with the jaw matched.
From Fig. 6, Fig. 7, as a kind of improved procedure that this is novel, the external frame of base portion 1 is cylindricality, and the cylindrical portion of its end face upper-end surface tooth 9 is provided with step 11.During this is novel, cylindrical base 1 there are screw 8, end-tooth 9, screw 10, step 11 and Transverse plane 12; Base portion 1 connect with other part outside by screw 8 and end-tooth 9 and fastening, and screw 10 is lifting screw, for carrying or lift; Step 11 and Transverse plane 12 structure for installing sealing component, to protect and to avoid end-tooth 9 that corrosion occurs.
