摘要： PURPOSE:To shorten the cycle time by temporarily assembling two parts on a pallet by use of movable spacers disposed therebetween, the releasing the spacers by use of a robot after the application of liquid by the robot, and thereafter by assembling both parts under pressure by use of an automatic assembly device. CONSTITUTION:A gear casing (GC) 4 and a ring gear (RG) 5 are set onto a set jig 30 on a pallet P, and a pair of right and left spacers 39 are disposed between the RG 5 and the flange part 4a of the GC 4. Then the RG 5 and the GC 4 are assembled temporarily together with the use of bolts 5, and a thread lock agent is applied to the outer peripheral surface of a bolt 5a and the facing surfaces of the RG 5 and GC 4, automatically by a robot. Then the spacers 39 are moved laterally by means of the robot so as to allow the RG 5 and GC 4 to abut against each other. Then, GC 4 and the RG 5 are pressed by a hydraulic cylinder, a pressing rod and a pressing punch so as to make both in close contact with each other, and thereafter they are assembled together with the use of the bolts 5. Thus, it is possible to eliminate the use of a gap forming device, thereby it is possible to shorten the cycle time.

摘要： PURPOSE:To continuously carry out press-fitting and bolt fastening works by one apparatus by arranging in parallel the screw factening units having a socket which contacts with a bolt in precedence with a press fitting head, onto a movable member having the press-fitting head. CONSTITUTION:A press-fitting head 2 consists of a guide cylinder 2a fixedly installed onto the lower part of a movable member 3, head body 2b which is freely inserted into the guide cylinder 2a and projectingly installed in the lower part, and a compression spring 2c compression-fitted between the guide cylinder 2a and the head body 2b. A plurality of screw fastening units 4 are installed downwardly onto the lower part of the movable member 3 so as to be positioned directly over each bolt hole 9a of a gear case 9 set onto an assembly board 6a. A socket 4a for the fitting onto the head 7a of a bolt 7 is installed at the lower edge of the screw fastening unit 4, and said socket 4a is urged downwardly by a compression spring 4b.
