One of part.
Background technology
Monoblock type jaw as the strength member in cross universal coupling, should meet certain assembly relation require,
Its own intensity meets the requirement of carrying again.Existing its shortcoming of monoblock type jaw is: 1, each face of jaw inner chamber adopts mostly
Multiple planes piece together connection, thus reducing effective entity of bottom, lead to the intensity of jaw to decrease, and jaw easily occurs disconnected
Split, the seamed edge being produced due to the junction that plane is pieced together, be also unfavorable for cast shaping process requirement；2nd, due to the cylindrical hole on arm
For imperfect cylindrical hole, be unfavorable for machining, can produce because allowing knife in machining dimensional discrepancy, cylindrical hole section
, thus easily there is the problems such as cut off sealing member, assemble difficulty when loading cross assemble in the non-full circle in face.So, how to make
Monoblock type jaw obtains, on the premise of meeting the physical dimensions such as inclination angle assembling, the technology difficulty that maximum intensity takes into account production simultaneously
Requirement is the difficult point of design monoblock type jaw structure.
Content of the invention
Problem to be solved by this invention be provide a kind of shape and structure rationally, processing and convenient when assembling, improve overall
The Hooks coupling universal coupling in life-span monoblock type jaw.Meanwhile, the Hooks coupling universal coupling monoblock type jaw intensity of the present invention is high, and its
During assembled in pairs, there is certain gap in the top of arm and inner chamber bottom, to avoid and interfere and make the entity of inner chamber to maximize
With the requirement meeting certain inclination angle.
Hooks coupling universal coupling of the present invention monoblock type jaw, it includes base portion, extended by base portion a pair with regard in revolution
The symmetrical arm of heart line, wherein, the middle part of each arm is provided with stepped hole, and stepped hole includes the d1 hole in outer portion and the d2 in inner chamber
Hole, the diameter in d2 hole is slightly larger than d1 hole, and there is the chamfering that an angle is β the outside of d1.Wherein, d1 hole is cylindrical hole, and d2 hole is not
Complete cylindricality stepped hole.
From the above, it may be appreciated that the stepped hole in the symmetric arms of monoblock type jaw of the present invention is made up of three sector holes, from cylindrical towards
The centre of gyration is followed successively by conical hole, cylindrical hole, cylindricality stepped hole, and wherein, the diameter in the d2 hole of increase is slightly larger than d1, so in machine
Dimensional discrepancy will not be produced, that is, the section of d1 cylindrical hole is full circle, the guide effect of taper hole in addition makes the present invention whole during processing
Easy to assembly during body formula jaw loading cross assemble, sealing member will not be cut off.Therefore, monoblock type jaw shape knot of the present invention
Structure rationally, reduces the difficulty in machining accuracy control aspect and assembling process.

Specific embodiment
Knowable to Fig. 1, Fig. 4, monoblock type jaw outline of the present invention is cylindroid, and it has the base portion with outer type
1 and extended by this base portion 1 a pair with regard to the symmetrical arm of the centre of gyration 32, be part pyramid like configuration at the cylindrical top of arm 2, with
When arm on be designed with column pore structure.
Wherein, the middle part of each arm 2 is provided with stepped hole 4, and stepped hole 4 includes the d1 hole in outer portion and the d2 in inner chamber
Hole, the diameter in d2 hole is slightly larger than d1 hole, and there is the chamfering that an angle is β the outside of d1.Wherein, d1 hole is cylindrical hole, and d2 hole is not
Complete cylindricality stepped hole.
From the above, it may be appreciated that the stepped hole in the symmetric arms of monoblock type jaw of the present invention is made up of three sector holes, from cylindrical towards
The centre of gyration is followed successively by conical hole, cylindrical hole, cylindricality stepped hole, and wherein, the diameter in the d2 hole of increase is slightly larger than d1, so in machine
Dimensional discrepancy will not be produced, that is, the section of d1 cylindrical hole is full circle, the guide effect of taper hole in addition makes the present invention whole during processing
Easy to assembly during body formula jaw loading cross assemble, sealing member will not be cut off.Therefore, monoblock type jaw shape knot of the present invention
Structure rationally, reduces the difficulty in machining accuracy control aspect and assembling process.
Knowable to Fig. 1, Fig. 5, in jaw, the inner chamber 7 of each arm 2 is curved surface, and curved surface includes upper curved surface, lower curved face
And fillet surface 13；Wherein, upper curved surface and lower curved face are adapted, and that is, the shape of top and the bottom curved surface is identical, and lower curved face is
Formed by after upper curved surface biasing certain value, be connected using fillet surface 13 between the curved surface of top and the bottom, thus inner chamber forms one
Individual overall and continuous curved surface.I.e. the inner chamber curved surface 7 of integral is an overall, continuous fitting surface, is in symmetric arms 2
Region symmetrical with regard to centrage 3 between top to bottom；
Inner chamber due to monoblock type jaw of the present invention is continuously many surface fittings, can increase effective entity of bottom,
The intensity of jaw is made to increase, not easy fracture, and be conducive to cast shaping process requirement；The inner chamber on cylindricality centerline hole top simultaneously
The inner chamber curved surface of curved surface and bottom has certain complementary relationship, to ensure it in assembled in pairs, the top of arm and inner chamber bottom
