The invention relates to the technical field of assembling and positioning tools, and discloses a tool for heavy precise part splicing and a using method.The tool comprises a height-adjustable spring pressing assembly and a wedge block pushing mechanism, the height-adjustable spring pressing assembly comprises a threaded stand column, an adjusting circular ring in threaded fit with the threaded stand column, a pressing circular ring and a compression spring, the initial height position of the pressing circular ring can be adjusted in the axial direction through the adjusting circular ring, splicing pieces with different loads can be flattened and form stable contact, and the compression spring bears the main load so as to improve the buffering and compliance capacity. The wedge block propelling mechanism comprises a first wedge block, a second wedge block, a third wedge block and a fourth wedge block which are stacked from top to bottom, the first wedge block, the second wedge block and the third wedge block are movable wedge blocks, and the fourth wedge block is a fixed wedge block; the wedge block propelling mechanism achieves axial propelling through thread driving and thrust bearing supporting and drives the height-adjustable spring pressing assembly to move downwards as a whole through relative sliding of wedge faces, so that a release space is provided after positioning is completed, and the performance after splicing is conveniently verified. And meanwhile, the wedge angle meets the self-locking condition so as to restrain reverse sliding.

The application discloses a quick-locking device, including a main housing, a retainer, a retainer, and balls. Both the retainer and the retainer are located within the inner cavity of the main housing. The retainer is connected to the main housing. The retainer has a spindle mounting channel at its center to accommodate the spindle, and ball mounting holes on its outer periphery. The ball mounting holes communicate with the spindle mounting channel, and the balls are fitted into the ball mounting holes. The spindle is located inside the balls, and the retainer is outside. The retainer has radial and axial locking wedges that limit the movement of the balls. The device locks when the balls are pressed against the retainer, and unlocks when the balls disengage from the retainer. The retainer, with its radial and axial locking wedges, works in conjunction with the balls to simultaneously lock and unlock the spindle radially and axially. This invention is simple to use, allows for quick locking and unlocking, is easy to disassemble, facilitates the locking and replacement of the locked components, and improves efficiency.
