Lead screw transmission structure for target plate three-way confining press

Abstract

The invention relates to a lead screw transmission structure for a target plate three-way confining press. The structure comprises a support frame, a driving motor, a lead screw nut pair and a drivingplate; the support frame is fixedly mounted on a frame of the target plate three-way confining press; parallel guide rail grooves are formed in the support frame; the lead screw nut pair is mounted in the support frame through a shaft base; the driving motor is mounted on the frame at the left end of the support frame, and is connected with a lead screw of the lead screw nut pair through a speedreducing mechanism; the driving plate is mounted in the guide rail grooves of the support frame, and is operated in the guide rail grooves; the bottom surface of the driving plate is fixedly connectedwith a connecting plate of the lead screw nut pair; and the right side end of the driving plate is hinged with a loading plate of the confining press through a pin shaft. The structure has the following beneficial effects: the structure is simple; the deflection is easily generated in transmission; and the separation of the transmission structure from the loading plate can be realized in the experimental process to effectively prevent damage of the transmission structure by the blasting vibration.

technical field [0001] The invention relates to projectile penetration experiment technology, in particular to a screw drive structure for a three-way confining press for a target plate. Background technique [0002] In order to study the influence of confining pressure on the penetration process, ballistic limit and target plate failure of the projectile under the condition of in-situ stress, provide systematic research on the movement law and penetration effect of the projectile under various in-situ stress conditions, and provide support for deep drilling Projectile structure design and deep national defense engineering defense provide reliable analysis data, and the design of three-dimensional confining pressure loading of the target plate is required for deep penetration test. At present, our self-designed three-way confining press uses the pressurization principle of small-angle inclined plates to install three axially perpendicular loading inclined plates in the box w...

Problems solved by technology

However, in the actual experiment process, when the simulated pressure is low, the vibration caused by the explosive moment of the projectile is relatively large, and it is easy to cause irreversible damage to the transmission mechanism driving the loading plate. Therefore, it is necessary to separate the transmission mechanism from the loading plate, but even In this way, the vibration of the frame will still affect the service life of the hydraulic transmission mechanism. Therefore, for experiments with low loading pressure, it is necessary to design another transmission structure
