A buffer spring 24 is arranged between the lower end of the guide pin 23 and the bottom of the guide sleeve 21; the upper end of the guide pin 23 passes through the limit ring 22 and then extends to the upper part of the guide sleeve 21.

The purpose of thus arranging the guide pin 23 and the guide sleeve 21 is: so that the guide pin 23 can always have a tendency of moving upward under the action of the elastic force of the buffer spring 24, and when the guide pin 23 is forced, the guide pin 23 can move downward against the elastic force of the buffer spring 24.

When the assembling machine tool of the axial and angle motor of the automobile electric adjusting pipe column works, firstly, the axial motor 2 to be assembled is placed on the positioning supporting block 11 on the primary assembling machine table 10 in a specified posture, and then the connecting piece 5 is assembled on the axial motor 2 through a screw; the tightening gun 31 is then moved to a desired position by holding the handle 32 of the tightening tool 17, and the screw is tightened to secure the engagement piece 5 to the axial motor 2. The tightening tool 17 is then reset, whereupon the assembly of the armature plate 5 on the electric machine 2 is completed.

After the above processes are completed, the pipe column body 1 is placed on the positioning block 14 in a uniform posture, attention is paid to inserting the guide pin 23 into the plug pin assembling hole on the pipe column body 1, and then the clamping cylinder 15 is started to enable the pipe column body 1 to be tightly pressed and fixed on the positioning block 14 through the pressing head 16.

After the tubular column body 1 is assembled on the positioning block 14, the axial motor 2 which completes the assembly of the connecting sheet 5 is placed on an installation station of the tubular column body 1; in this process, it is necessary to manually pull the guide pin 23 out of the column body 1 to be out of contact with the column body 1, then place the axial motor 2 on the installation site of the column body 1, and then release the guide pin 23, at which time the guide pin 23 will be inserted into the plug pin fitting holes of the column body 1 and the axial motor 2.

After the tubular column body 1 is placed, the driving cylinder 35 of the press-fitting device 18 acts to drive the press-fitting head 37 to move to the position right above the bolt assembling holes of the tubular column body 1 and the axial motor 2. Then the pushing cylinder 38 drives the supporting block 39 to move to the position right under the pin fitting hole of the column body 1 and contact with it. The support block 39 thus provides support for the column body 1.

The supporting block 39 is moved to the lower side of the column body 1, and then the plug 4 is inserted into the plug fitting hole of the axial motor 2. The press-fitting cylinder 36 of the press-fitting unit 18 is then actuated to insert the plug pin 4 into the plug-pin fitting holes of the pipe string body 1 and the axial motor 2 through the press-fitting head 37. In the process, the press-fitting head 37 pushes the guide pin 23 out of the column body 1.

After the press-fitting head 37 completes the assembly of the plug 4, the press-fitting device 18 is reset. Then, manually rotating the control hand wheel 19 to control the extrusion screw rod 13 to move towards the tubular column body 1; in the process, the extrusion screw rod 13 extrudes the moving parts in the tubular column body 1 through the extrusion tip 20, so that the moving parts move to the specified position, and then the operation hand wheel 19 stops rotating. The engagement piece 5 is then fixedly connected to the moving part of the column body 1 by means of a screw. And then the extrusion screw rod 13 is driven to reset by operating the hand wheel 19.

After the extrusion screw 13 is reset, the rotating motor 9 drives the supporting turnover plate 8 to rotate to a vertical state. Then, a clamp spring is arranged at one end of the bolt 4; the angle motor 3 is then mounted to the column body 1.

After the angle motor 3 is installed on the tubular column body 1, the rotating motor 9 drives the supporting turnover plate 8 to rotate to a horizontal state. And then the tubular column body 1 which finishes the assembly of the angle motor 3 and the axial motor 2 is taken down, so that the assembly machine tool of the axial direction and the angle motor of the automobile electric adjusting tubular column completely finishes the assembly work of the axial motor and the angle motor, and the assembly machine tool can enter the next working cycle.

This tubular column axial and angle motor's assembly lathe is transferred to car electricity, compact structure, design benefit can assist the artifical assembly work of accomplishing the axial motor 2 and the angle motor 3 of tubular column is transferred to car electricity to solved the problem that the assembly efficiency is low that the tubular column was transferred to car electricity to axial motor 2 and the current assembly mode of angle motor 3 had in the tubular column, be particularly suitable for the needs that tubular column axial and angle motor 3 assembly was used are transferred to car electricity.
