Abstract

The invention discloses an elastic locking device, belongs to the field of fixing and clamping techniques, and aims at solving the problems of poor overall bearing capacity and poor rigidity of a machine in the prior art and achieving continuous moving and a locking function of a moving cross beam. The elastic locking device is characterized in that a non-integral cylinder is fixedly connected with a side stand column through a rectangular-section member, the non-integral cylinder is in clearance fit with an open circular hole in the moving cross beam, two ends of an opening of the circular hole are used as two elastic clamping pieces of the moving cross beam, and a clearance allowance is reserved between an opening formed by the two elastic clamping pieces and the rectangular-section member. The distance of the two elastic clamping pieces is adjusted through hydraulic oil cylinder clamping mechanisms, then the non-integral cylinder can be clamped or loosened, and at least one set of hydraulic oil cylinder clamping mechanisms can achieve clamping when the moving cross beam moves to any position. According to the elastic locking device, the side stand column can be connected with a clamping part through the arranged non-integral cylinder, the side stand column can be designed to be in any size and any structural shape, the overall bearing capacity of the machine is improved, and the rigidity of the machine is enhanced.

Description

technical field

[0001] The invention belongs to the technical field of fixing and clamping, and in particular relates to an elastic locking device for a moving beam and a side column in a machine with a frame structure. Background technique

[0002] In many frame-structured machines, it is required that the movable crossbeam can move continuously, and it should be locked with the side column at any position, so that they can be integrated so as to improve the rigidity of the machine. The traditional testing machine has a small working load, and the bearing requirements can be met only by the cylindrical side column. Therefore, most of them use the method of moving the beam through the cylindrical side column to implement clamping. For machines with super-heavy loads, only using cylindrical side columns to carry the load can no longer meet the requirements of the overall load-bearing capacity of the machine or cause poor rigidity; in the clamping process of traditional testin...
