Multi-axis hole assembly is a typical complex assembly task. Different from simple shaft hole assembly, the correct assembly relationship between multiple pairs of shaft holes must be satisfied at the same time to successfully complete this type of assembly task. For this type of assembly operation, there is no suitable assembly method and corresponding assembly device at present. Through literature search, it was found that Xi Anmin and others wrote an article "Assembling Machine for Cylinder Head Bolts of Refrigerator Compressors" in "Combined Machine Tool and Automatic Processing Technology", No. 3, 1999, P19-21. This article introduced a cylinder head bolt assembly machine. The automatic assembly machine is used to complete the uniaxial hole assembly of the bolt. The equipment is mainly composed of pneumatic wrench assembly, cylinder head clamp body, blanking mechanism, guide slideway, main slideway and support. The cylinder head clamp body is used to tighten the cylinder head assembly. After tightening, the center of the bolt corresponds to the center of the wrench head extending into the clamp body, and the bolt points to the guide slide of the crankcase; the guide slide is the access channel of the crankcase, so that the screw hole The position is basically aligned with the screw, and the air motor is rotated; the unloading device is used to unload the assembled workpiece, and the main slideway is the track for the workpiece to flow on the production line. Because this assembly machine is only suitable for simple shaft hole assembly of bolts, it cannot complete simultaneous assembly actions between complex parts with multi-axis holes.

The slider moves, driving the turning table and the inclined cylinder to move, the inclined cylinder enters and exits air, and the turning table turns ±90° around the hinge.

The present invention designs the three-axis hole assembly machine for the complex assembly task of the three-axis hole, and is well applied in the multi-axis hole deformation assembly of the robot. quality and efficiency. When working, the motor drive device moves, the motor shaft rotates, and the lead screw in the electric moving unit rotates, driving the nut, the slider and the turning table forward, the slider in the electric moving unit moves in place, and the inclined cylinder in the turning device takes in air. The turning table turns 90°, the motor drive device stops, the tooling fixture is in place, the air cylinder in the tooling fixture is fed into the air, and the three guide rods are pushed forward along the three holes opened by the guide pressing device, and aligned with the three holes opened on the turning table , the motor drive device moves, the turning device moves forward, and the press-fit assembly of the three-axis insertion into the three holes is completed, the motor drive device stops, and the balance device plays the role of balancing the press-fit force; the three-axis hole assembly action is completed, and the cylinder in the jig is released , the three guide rods are retracted along the three holes of the guide pressing device, the air is released from the inclined cylinder, the turning table is turned over -90°, the motor drive device moves, the turning device moves backward, and returns to the initial position, the motor drive device stops, and a job is completed cycle.

The present invention has substantive features and significant progress. The present invention is designed for an actual three-axis hole assembly task after analyzing the characteristics of multi-axis hole assembly tasks, and can complete complex three-axis hole assembly actions similar to human hands. The assembly machine has strong practicability, wide adaptability, is easy to realize in production practice, and can adapt to various similar assembly operations after modification.
