First, the transfer robot transfers the base shell assembly 12, which is a work target, to be mounted on the seating jig 116a of the seating rotation part 112 of the loading station 110a in a vertical state, and then the clamper of the seating rotation part 112. 114 is fixed by clamping the upper end of the base shell assembly 12 loaded seated.

In this process, the horizontal plate 116 on which the seating jig 116a is first formed may be appropriately adjusted by driving of the lifting motor 118 having the height according to the model of the base shell assembly 12 to be loaded.

Thereafter, the seating rotation part 112 is rotated by a predetermined angle by the driving of the rotary motor 119, and the loaded base shell assembly 12 is loaded by the rod assembly insertion station 110b-1 or 110b-2 corresponding to each model. ) And then stop, and in this case, when the base shell assembly 12 is rotated and transported by the seating rotation part 112, the clamper 114 of the previous station side is released before rotation. After being transported and rotated, it is fixed by the clamper 114 on the corresponding station side, which is a common matter.

Subsequently, the rod assembly inserting device 120 on the side of the corresponding rod assembly insertion station 110b-1 or 110b-2 where the base shell assembly 12 is positioned is operated, that is, the guide jig which is opened in its distal end portion. The guide jig 123 of the insertion unit 124 is coalesced by the driving of the clamping cylinder 124a to form a cylindrical shape.

Next, the guide bar upper and lower moving parts 122a of the guide bar insertion unit 122 are advanced by driving the forward and backward cylinders 122b and moved to the upper part of the base shell assembly 12, and then the guide bar upper and lower parts are moved. Inside the inner tube of the base shell assembly 12 of the lower base shell assembly 12 through the guide jig 123, which is moved downward by the guide bar 121 is moved downward by the air pressure introduced into the upper side of the eastern portion (122a) The predetermined length is inserted into, thereby completing the centering of the inner tube of the base shell assembly 12.

Subsequently, the combined guide jig 123 of the guide jig insertion unit 124 is lowered slightly by driving of the lifting cylinder 124b, and a predetermined length is inserted into the upper end side of the base shell assembly 12 of the lower base. The inner shell of the guide jig 123 is restrained and fixed by restraining the shell assembly 12, and the upper end of the inner tube of the base shell assembly 12 which is already centered by the insertion of the guide bar 121 is restrained. The outer cylinder constrains the outer tube of the base shell assembly 12, which is already fixed by the clamper 114 of the indexing device 110, to fix it more firmly.

Then, the guide bar 121 is moved to the upper side to be removed from the base shell assembly 12, which is carried out by the air flowing into the lower side of the guide bar up and down moving portion 122a, the guide bar up and down moving portion 122a Is reversed by the driving of the forward and backward cylinder 122b to return to its original state.

Next, the rod assembly 14 to be assembled by the transfer robot is transported so that its upper end is gripped by the gripper 126a of the rod assembly insertion unit 126 so as to be positioned in a vertical state, and then the gripper 126a is moved back and forth. The rod assembly 14 positioned on the upper portion of the base shell assembly 12 by the driving of the truth holder 126b, and then lowered and gripped by the driving of the elevating motor 126d, is the lower base shell assembly. A predetermined length is inserted into the inner tube of 12, and the rod assembly 14 inserted downward is guided through the guide jig 123, which is slightly inserted into the upper end of the base shell assembly 12. .

Subsequently, when the insertion assembly of the rod assembly 14 is completed in this manner, the gripper 126a of the rod assembly insertion unit 126 releases the grip on the rod assembly 14 and is raised and retracted to return to its original state. , The guide jig 123 of the guide jig insertion unit 124 is also raised and unfolded to return to its original state.

Further, the base shell assembly 12 in which the rod assembly 14 has been inserted and assembled is rotated at a predetermined angle by the seating rotation part 112 to be positioned at the rod assembly taking out station 110c, and then the rod assembly taking out device. 130 is activated.

That is, the pressing jig 132a of the oil seal supporting unit 132 is advanced by the driving of the forward and backward cylinder 132b to be positioned directly above the base shell assembly 12 at the lower portion thereof, and then the lifting motor It is lowered by the driving of 132c and positioned to close a part of the upper end of the base shell assembly 12.

Subsequently, the gripper 134a of the rod assembly withdrawal unit 134 provided on the upper side is lowered and positioned as it is driven by the lifting motor 134b, and then the upper end portion of the rod assembly 14 inserted and gripped is gripped. After that, as the lift motor 134b is driven up as it is, the inserted rod assembly 14 is drawn out to the longest state, and the pressing jig 132a of the oil seal support unit 132 opens the oil seal. The oil seal is prevented from being pulled out together with the rod assembly 14 being pushed out.

Thereafter, the pressing jig 132a of the oil seal support unit 132 is raised and retracted to return to its original state, thereby completing the withdrawal process of the rod assembly 14.

Further, the base shell assembly 12, from which the rod assembly 14 is drawn out, is rotated at a predetermined angle by the seating rotation part 112 and positioned at the unloading station 110d side, and then the transfer robot is placed on the base shell assembly. (12) is taken out and transferred to the next step.

As a result, the insertion assembly and withdrawal process of the rod assembly 14 with respect to one base shell assembly 12 is completed, and at the same time, the above-described operation process is performed with respect to the plurality of base shell assemblies 12.

In the foregoing description, it should be understood that those skilled in the art can make modifications and changes to the present invention without changing the gist of the present invention as merely illustrative of a preferred embodiment of the present invention.

According to the present invention, it is possible to perform the insertion assembly and withdrawal operation of the rod assembly with a single device, significantly reducing the device cost, improve the space utilization for installation of the device, and by reducing the work time An effect that can improve productivity can be achieved.
