To achieve these goals, the technical solution of the utility model is as follows:
A kind of press for crimping torsion beam back axle sleeve pipe, lining, it is characterized in that, it comprises platen, described platen is provided with left end for compressing the left hold-down mechanism of lining, pipe box on torsion beam back axle and right-hand member for compressing the right hold-down mechanism of lining, pipe box on torsion beam back axle, and described left hold-down mechanism and right hold-down mechanism are provided with separately C type floating seat, control guide rail and the control cylinder of the C type floating seat direction of motion; The front end of described platen is also provided with the stationary fixture for permanent twist beam back axle.
In an embodiment of the present utility model, described C type floating seat also comprises float plate and lower float plate, between described upper and lower float plate, is provided with connecting plate, and fluctuating, Ban Yu connecting plate circle goes out certain space.
In an embodiment of the present utility model, the madial wall both sides of described C type floating seat are respectively arranged with by the pressure head of control cylinder controlled motion and the seat that holds out against moving with C type floating seat; When assembling, pressure head is connected with lining, holds out against seat and is connected with sleeve pipe.
In an embodiment of the present utility model, torsion beam back axle is fixed on stationary fixture by the mode of plane and two pits.
Press for crimping torsion beam back axle sleeve pipe, lining of the present utility model, compare with present product, together with the lining on torsion beam back axle being crimped on sleeve pipe by hold down gag, operation is simple, easy to operate, and production efficiency is high, product quality is secure, simple in structure, very practical, realize the purpose of this utility model.
Feature of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained and be well understood to.

Fig. 2 is the structural representation of the press for crimping torsion beam back axle sleeve pipe, lining of the present utility model;
Fig. 3 is the front schematic view of Fig. 2;
Fig. 4 is the side schematic view of Fig. 2;
Fig. 5 is that torsion beam back axle is fixed on the schematic diagram on stationary fixture.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the utility model.
As Fig. 2, 3, shown in 4, of the present utility model for crimping torsion beam back axle sleeve pipe, the press of lining, it comprises platen 10, described platen is provided with left end for compressing lining on torsion beam back axle, left hold-down mechanism 11 and the right-hand member of pipe box are used for compressing lining on torsion beam back axle, the right hold-down mechanism 12 of pipe box, described left hold-down mechanism and right hold-down mechanism are provided with C type floating seat 20 separately, control guide rail 21 and the control cylinder 22 of the C type floating seat direction of motion, described C type floating seat also comprises float plate 23 and lower float plate 24, on described, between lower float plate, be provided with connecting plate 25, upper, lower float plate and connecting plate circle go out certain space, the madial wall both sides of described C type floating seat 20 are respectively arranged with by control cylinder 22 through upper, the pressure head 26 that lower float plate and connecting plate circle go out certain space controlled motion with C type floating seat mobile hold out against seat 27, when assembling, pressure head is connected with lining, holds out against seat and is connected with sleeve pipe, wherein C type floating seat can horizontally slip the guide rail that is positioned at its chassis is cofree, hold out against the two ends that seat and pressure head are connected to C type floating seat, both are in the same center line, and cylinder can promote its motion also can be mutually close.
As shown in Figure 5, in the utility model, the front end of described platen is also provided with the stationary fixture 30 for permanent twist beam back axle, and the mode by plane and two pits is fixed on stationary fixture 30; The first positioning datum axle 31, the second positioning datum axle 32 lay respectively at the torsion crossbeam two ends of torsion beam back axle, and both symmetrically and be positioned on same center line; When right hold-down mechanism press-fits the right lining, have a positioning reference plane between the right LL and stationary fixture, this positioning reference plane, perpendicular to two positioning datum axles, forms the locate mode of plane and two pits.When left hold-down mechanism press-fits left side lining, locate in the same way.
During work, cylinder promotion C type floating seat one end of C type floating seat bottom surface holds out against seat 27 and holds out against product sleeve pipe, when the pressure head of lining is housed, stretches out and move to while being about to enter sleeve pipe, the center-leakage type magnetic valve of control cylinder is in meta, now C type floating seat can be free to slide on base rail, when pressure head moves on, because C type floating seat is free to slide state in (left and right directions), pressure head and the spacing that holds out against between seat are more and more less so, until bushing coining is entered to sleeve pipe, complete sleeve pipe assembling; Anti-Extrusion is also this principle.Use center-leakage type magnetic valve cylinder piston rod state in free-extension when meta, thereby realized the both sides press fit motion process that the cylinder propelling press-fiting in earlier stage holds out against pre-guiding and later stage; Used the principle of active force reaction force, press-fited that in process, to hold out against between seat and pressure head stressed size identical, opposite direction, thus realize the positive and negative compressional movement that press-fits process.Simplified project organization, and shared a servo cylinder pressure of power output mechanism, a pressure sensor, has saved manufacturing cost greatly.
Adopt press can make pressing method simple, reliable, stable, the present invention can realize the cylinder propelling press-fiting in earlier stage workpiece is carried out to just location (or leading in advance) and clamping, and float and to press-fit assembling motion process in the workpiece two ends in later stage, this assembling can realize forward and reverse pressure assembly work, without accurate location, simplify press mounting machine tool structure, stablized and press-fit quality, for boosting productivity, there is practical significance.Torsion beam back axle is located by product stationary fixture, to guarantee at the stability press-fiting and accuracy.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and description, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
