As shown in FIGS. 36 and 37, a through hole 2 is formed in the center of an arm body 1 made of aluminum alloy, and a chip 3 made of iron-based sintered material is provided at one end of the arm body 1 to contact the cam. It is known that a mounting hole 4 for mounting a hydraulic mechanism is formed at the other end of the arm body 1. In this rocker arm, sliding parts other than the tip 3 (cam sliding surface part) (for example, the part where the plunger of the hydraulic mechanism provided in the mounting hole 4 of the arm body 1 contacts the mounting hole 4, etc.) ), the surface of the aluminum alloy is converted to porous hard aluminum oxide at a defined depth by anodizing treatment, and then this porous structure is injected with tetrafluoride resin (Teflon resin). ) is impregnated with so-called Toughflam treatment. [0003]

[Problems to be Solved by the Invention] When the rocker arm is subjected to Toughflam treatment, since the chip 3 attached to one end of the arm body 1 is made of iron-based sintered material,
It is not possible to perform anodization treatment in that state, so a pretreatment process such as masking the chip 3 by covering it with resin or a process of lining up a large number of rocker arms and connecting them to the electrodes is required, and the rocker arm is removed after the Toughflam treatment. A post-processing process such as a process of removing the mask from the electrode or a process of removing the masking is required. Conventionally, these pre-processing steps and post-processing steps have been carried out manually, which poses a problem of poor workability, and it has been desired to mechanize them to save labor. [0004] Therefore, the present inventors attempted to mechanize the pre-treatment process and post-treatment process of the Tafram treatment, and completed a series of mechanized lines.

The intervals between each workpiece are widened to a predetermined equal interval. [0026] At this time, each pair of gripping tools 206 of the chuck mechanism 20 is positioned above each workpiece with a widened interval. In this state, the lifting cylinder 200 lowers the lifting frame 202 along the guide rod 201, and a pair of gripping tools 206 are connected to brackets 204 arranged on the lower surface of the lower plate 203 of the lifting frame 202 by pins 205. is lowered so that each workpiece is positioned between each pair of gripping tools 206, and the bifurcated lower end of each gripping tool 206 is fitted into the three rod-like bodies 125 on which the workpieces are attached. [0027] Next, the traveling table 122 is moved above the attitude changing table 18 by the rotating machine 124. As a result, as shown in FIG. 16, the workpiece, which has been supported by the shaping plate 216 and has been in a hanging position with the mounting hole 4 facing downward, now comes into contact with the upper surface of the attitude changing table 18.

The workpiece held between the workpieces 6 is pressed from below, and each pair of adjacent holding claws 6b of each workpiece holding tool 6 grips the lower part of the workpiece. [0032] Next, by raising the elevating plate 210 using the opening/closing cylinder 211 and lifting up the support shaft 209 and the closure device 208 at its lower part, each pair of gripping devices 20
6 rotates around the bin 205 by the biasing force of a spring 207. For this reason, each pair of gripping tools 206
Since the lower ends of are opened, the gripping state of the workpiece by the gripper 206 is released. In this state, by lowering the table 221 to a predetermined position by the mounting cylinder 220, the workpiece is moved to the rack 5 side while being held by the workpiece holding tools 6 of the workpiece mounting rod 5e of the rack 5 on the table 221. [00331] Next, the lifting cylinder 200 raises the lifting frame 202 to a predetermined height, and the rotating machine 124 returns the traveling platform 122 to the unloading position B side of the work transfer mechanism 10. In this case, the three rod-shaped bodies 125 attached to the traveling platform 122
The carriage 122 is returned to a position facing the three book mounting rods 106 to which workpieces are still mounted. Then, by the same procedure as described above, three workpieces are attached to the remaining three attachment rods 106.
The book is clamped by the work clamping tool 6 on the remaining three work mounting rods 5e of the rack 5 via the book rod-shaped body 125.
