Abstract

The invention relates to a hole connecting device for being connected with a through hole in a workpiece. The hole connecting device comprises a connecting cylinder, wherein an inserting connection end for penetrating through a to-be-connected through hole is arranged at the lower end of the connecting cylinder; a sliding block movably arranged in the radial direction of the connecting cylinder isarranged in the inserting connection end; on the movable stroke, the sliding block is provided with a stretching position and a retracting position; the stretching position stretches out of the connecting cylinder to be in retaining stop fit with the orifice edge of the through hole, and the retracting position retracts into the connecting cylinder to remove the retaining stop fit; a fastening rod is arranged in the connecting cylinder and is movably arranged in the axial direction of the connecting cylinder through thread driving; and the sliding block is in transmission connection with thefastening rod to realize motion towards the stretching position. With adoption of the scheme, the problem in the prior art that locking position cannot be carried out on certain end of the through hole, so that hole connection is difficult or cannot be carried out is solved.

Description

technical field [0001] The invention relates to a hole connecting device for connecting with a through hole on a workpiece. Background technique [0002] At present, bolt connection or screw connection is often used to connect workpieces with through holes. This connection method is simple in structure, reliable in connection, mature in technology, and low in cost. Install the nut and then lock it, or pass the screw through one end of the through hole, and then screw it into the threaded hole on the workpiece located at the other end of the through hole. [0003] However, in the production, processing and assembly process of some large workpieces, due to the large size of the workpiece or the sealed structure of the workpiece, it is often difficult or impossible for workers to touch the other end of the through hole on the workpiece during operation. If the thread is set on the workpiece, screw connection cannot be used, which makes the hole connection locking between the w...
