Fast pre-pressing device in limited space

Abstract

The invention relates to the technical field of diesel engines and provides a fast pre-pressing device in a limited space. The fast pre-pressing device in the limited space is arranged in a groove ina rubber vibration isolator, and is provided with a short double-head bolt; the two ends of the short double-head bolt are a screw I and a screw II correspondingly; the screw I and the screw II are connected into a whole in a transition manner through a polished rod; the screw I is in threaded connection with a screw hole in one side of the groove of the rubber vibration isolator; the outer wall face of the screw II has an external thread; a loop is of a barrel-shaped structure with a step type through hole in the center; the step type through hole is of a big-end-up structure; an internal thread connected with the screw II is on the upper portion of the inner wall face of the step type through hole; a screw cap of a bolt is located in a large-diameter hole of the step type through hole; and a screw of the bolt stretches out of the step type through hole and is in threaded connection with a threaded through hole in the other side of the groove of the rubber vibration isolator. The fastpre-pressing device in the limited space fast and effectively solves the pre-pressing problem of an effective space of the rubber vibration isolator, the reliability of the rubber vibration isolatoris improved, and the service life of the rubber vibration isolator is prolonged.

Description

Technical field [0001] The invention and the technical field of diesel engines particularly relate to a rapid pre-compression device in a limited space. Background technique [0002] At present, large and medium-sized diesel engines have a lot of vibration and noise during use. The commonly used measure is to use a vibration isolation base to reduce vibration and noise; the main body of vibration isolation of the vibration isolation base is a rubber vibration isolator. Due to the small installation space, the current It can only rely on external force or the diesel engine’s own gravity to pre-press the rubber vibration isolator to make the rubber vibration isolator reach a suitable compression amount, which is low in efficiency, and the deformation of the rubber vibration isolator will exceed its maximum deformation capacity when the diesel engine shakes violently. Failure of the vibration isolator. Summary of the invention [0003] The purpose of the present invention is to prov...

Problems solved by technology

[0002] At present, large and medium-sized diesel engines vibrate and make a lot of noise during use. A common measure is to use a vibration isolation base to reduce vibration and noise; the main body of the vibration isolation base is a rubber vibration isolator. Due to the narrow installation space, currently It can only rely on external force or the self-gravity of the diesel engine to pre-press the rubber vibration isolator so that the rubber vibration isolator can reach a suitable compression amount, and the efficiency is low, and the deformation of the rubber vibration isolator will exceed its maximum deformation capacity when the diesel engine shakes violently.
