Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
One draws horse swivel joint to comprise draw rod attachment part and part joint, one end of draw rod attachment part is connected with drawing the end winding support of Malaysia and China's pull bar, the other end is fixedly connected with one end of part joint, the other end of this part joint extends internally from end face and offers a receiving hole, this receiving hole is drawn part (Spielpassung between receiving hole and part for being sleeved on, or offer internal thread in receiving hole and with part scyewed joint), receiving hole, part joint, draw rod attachment part, draw Malaysia and China's pull bar coaxially to arrange.This draws horse swivel joint solve La Mala bar and drawn the problem of sliding wear between part; what employ this swivel joint draws Marko to ensure not having relative sliding wear between part with La Mala bar; protect the integrity being disassembled part He drawing Malaysia and China's pull bar, extend and draw horse working life.
In the present embodiment, as shown in Figures 2 and 3, draw rod attachment part comprises the first cylindrical body 21 and the second cylindrical body 24.One end (upper end in Fig. 2 and Fig. 3) of first cylindrical body 21 extends internally from end face and offers tapped hole, draw the end of Malaysia and China's pull bar to be provided with the outside thread closed with corresponding threaded holes, achieve connecting of draw rod attachment part and pull bar by the cooperation of internal and external threads.Second cylindrical body 24 is vertically set on the end face of the other end (lower end in Fig. 2 and Fig. 3) of the first cylindrical body 21, and the diameter of this second cylindrical body 24 is less than the diameter of the first cylindrical body 21 and outer peripheral surface is provided with in order to the outside thread with part joint scyewed joint.Second cylindrical body 24, first cylindrical body 21, tapped hole are coaxially arranged.
As shown in Figures 2 and 3, part joint is a three cylindrical body 23, offers ladder hole in this three cylindrical body 23, and this ladder hole and three cylindrical body 23 are coaxially arranged; In ladder hole, large diameter hole is receiving hole, the hole wall of small diameter bore offers the internal thread matched with outside thread on the second cylindrical body 24, achieves connecting of draw rod attachment part and part joint by externally threaded cooperation.
In order to prevent wearing and tearing between the first cylindrical body 21 and three cylindrical body 23, so as shown in Figures 2 and 3, the second cylindrical body 24 is set with end face bearing 22, end face bearing 22 is resisted against on the end face of the first cylindrical body 21 and three cylindrical body 23.The upper-end surface of end face bearing 22 be resisted against the first cylindrical body 21 is provided with the second cylindrical body 24 end face on, on the lower end surface of end face bearing 22 and three cylindrical body 23, the opening place end face in ladder hole medium-small diameter hole leans.
In order to opposite end spherical bearing 22 carries out spacing, so as shown in Figures 2 and 3, the end face of three cylindrical body 23 is provided with circular groove, end face bearing 22 is nested in this circular groove.End face bearing 22 and circular groove need arrange suitable gap, prevent using process middle-end spherical bearing 22 from occurring beat.
Working life of part is reduced in order to prevent from wearing and tearing, so the hardness of end face that the first cylindrical body 21 contacts with end face bearing 22 is greater than HRC58, and fine finishing again after heating.The hardness of the end face that three cylindrical body 23 contacts with end face bearing 22 is greater than HRC58, and fine finishing again after heating.
This draws horse swivel joint solve La Mala bar and drawn the problem of sliding wear between part, what employ this swivel joint draws horse, when drawing horse traction bar to rotate, first cylindrical body 21 and pull bar synchronous rotary, three cylindrical body 23 and part geo-stationary, end face bearing 22 ensures that the first cylindrical body and three cylindrical body 23 can rotate freely, without clamping stagnation.Pull bar axial rotary power is passed through the first cylindrical body 21, end face bearing 22, three cylindrical body 23 is delivered on part simultaneously.Finally realize part dismounting requirement.Thus ensure that there is no relative sliding wear between part with La Mala bar, protect the integrity being disassembled part He drawing Malaysia and China's pull bar, extend and draw horse working life.Adopt end face bearing 22 to achieve rotating freely between La Mala bar and part, decrease the friction torque in using process between part and pull bar, increase and draw Malaysia and China's pull bar screw-down torque, improve and draw horse ability to dismantle.
Draw horse swivel joint except adopting said structure, draw rod attachment part and part joint can also be designed to cuboid or polygonal body etc.
In sum, content of the present utility model is not limited in the above-described embodiments, and those skilled in the art can propose other mode of execution easily according to guiding theory of the present utility model, and these mode of executions are all included within scope of the present utility model.
