Abstract
The invention provides a connecting rod and barrel bearing structure of a press machine. The technical scheme includes that the connecting rod and barrel bearing structure comprises a connecting rod, a barrel and a hinge pin, wherein the connecting rod is connected with the barrel by the hinge pin, and the top of the connecting rod is in sliding contact with the barrel. The connecting rod and barrel bearing structure has the advantages that the connecting rod and barrel bearing structure is high in bearing capacity, deformation of parts is reduced, and rigidity and working stability of the integral machine are improved.
Description
Technical field
The present invention relates to mechanical transmission fields, relate in particular to a kind of jointed gear unit, specifically the bearing structure of a kind of press connecting rod and swivel nut.
Background technology
Forcing press be a kind ofly be widely used in cutting off, the equipment of the technique such as punching, blanking, bending, riveted and shaping.The kind of drive of forcing press is generally bent axle and drives the eccentric disc rotation, the motion of eccentric disc drivening rod, and connecting rod band movable snail sleeve moves back and forth along guider.At present the general bearing pin that adopts is connected between the connecting rod of forcing press and the swivel nut, and swivel nut passes to connecting rod with suffered stamping press by bearing pin, owing to bearing pin is smaller, poor rigidity, bearing capacity is low, so be easy to cause the bearing pin distortion when forcing press is worked, even fracture, impact is normally produced.
Summary of the invention
The technical problem to be solved in the present invention provides that a kind of bearing capacity is strong, the press connecting rod of good reliability and the bearing structure of swivel nut.
Technical scheme of the present invention provides the bearing structure of a kind of press connecting rod and swivel nut, comprises the bearing pin of connecting rod, swivel nut and connection connecting rod and swivel nut, described connecting rod top and swivel nut sliding-contact.
After adopting the technical program, when stamped workpieces, swivel nut is directly passed to connecting rod with suffered stamping press, bearing pin is bearing load not, just realize the motion of connecting rod band movable snail sleeve as attaching parts, improved the bearing capacity of syndeton between connecting rod and the swivel nut, increased the rigidity of complete machine.
As improvement, be fixed with on the described swivel nut and support watt, described support watt contacts with the connecting rod top slide.After adopting this improvement project, connecting rod top and support watt sliding-contact, and not with the direct contact friction of swivel nut, when the bearing shell excessive wear, can change bearing shell, and do not need to change whole swivel nut, both convenient for maintaining had been saved again maintenance cost, and the bearing shell wearability is good, frictional resistance is little, has improved service life and transmission efficiency.
As improvement, be provided with connecting rod bearing shell between described connecting rod and the bearing pin, and connecting rod bearing shell radially slides with bearing pin and is connected.After adopting this improvement project, connecting rod not with the direct contact friction of bearing pin, avoid causing the wearing and tearing of connecting rod, when connecting rod bearing shell or bearing pin serious wear, connecting rod bearing shell or bearing pin changed and get final product, convenient for maintaining, and reduce maintenance cost, simultaneously also increase lubricity, improved machinery driving efficiency.
As improvement, be respectively equipped with the bearing pin end cap that prevents that bearing pin from rotating at the bearing pin two ends.After adopting this improvement project, the relative swivel nut of bearing pin can not produce slip, can not cause wearing and tearing to swivel nut, has improved the service life of swivel nut, and the job stability of complete machine.
The invention has the beneficial effects as follows: improved the bearing capacity that connects between connecting rod and the swivel nut, reduced the distortion of parts, improved rigidity and the job stability of complete machine.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention;
Shown in the figure:
1, connecting rod, 2, swivel nut, 3, bearing pin, 4, support watt, 5, connecting rod bearing shell, 6, the bearing pin end cap.
The specific embodiment
The specific embodiment below in conjunction with the bearing structure of 1 pair of press connecting rod of the present invention of accompanying drawing and swivel nut is described in detail below.
A kind of press connecting rod as shown in Figure 1 and the bearing structure of swivel nut comprise connecting rod 1, swivel nut 2, and connecting rod 1 and swivel nut 2 are provided with connecting rod bearing shell 5 by bearing pin 3 pin joints between connecting rod 1 and the bearing pin 3, and connecting rod bearing shell 5 radially slides with bearing pin 3 and is connected.Bearing pin 3 two ends are provided with the bearing pin end cap 6 that prevents that bearing pin 3 from rotating, connecting rod 1 top and support watt 4 sliding-contacts that are located on the swivel nut 2.
When carrying out press work, swivel nut 2 is directly passed to connecting rod 1 with the stamping press that is subject to, and bearing pin 3 does not stress or is subjected to very little power, and the connection between connecting rod and the swivel nut has larger bearing capacity, and complete machine all has good rigidity and stability.
In the above-described embodiments, preferred forms of the present invention is described, obviously, under inventive concept of the present invention, still can make a lot of variations, for example bearing pin can be fixedly connected with connecting rod, bearing pin adopts to radially slide with swivel nut and is connected simultaneously, adds bearing shell between bearing pin and the swivel nut.Any change of making under inventive concept of the present invention all will fall within the scope of protection of the present invention.
