Abstract

PURPOSE:To rationalize the arrangement of automatic assemblying devices so that the arrangement may be simplified, by intermittently rotating a turntable on which a plurality of workheads are laid at a predetermined pitch, at a pitch plural times larger than the above-mentioned pitch. CONSTITUTION:Two kinds of workheads (a, b) are arranged on the peripheral part of turntable 10, at a constant pitch. The workheads are intermittently rotated two pitchs by two pitchs together with the turntable 10 after the workheads receives works at a working position P1 from a work supply device 20. AT a working position P5, the work 1 is press-fitted into a sheathed casing 2, is covered with a cap 3 at a working position P7, and is spot-welded at a working position P9. The assembled article is shifted to the work head (b) at a position P12 from a position P11 while it is made upside-down, is covered with a cap 4 at a position P7 and is welded at a position P9. The completed product is discharged at a position P10. The arrangement may be simplified by juxtaposing the working positions having the same function.

Description

DETAILED DESCRIPTION OF THE INVENTION This ridge 94 relates to a method of assisting a turn team for assembling workpieces continuously.

When assembling workpieces such as electrical parts using the turntable method, work bodies are placed around the turntable in the order of assembly. Example H, @
/ As shown in the figure, the metal surface is gold and the small work made of 4 is <1+
Place the cylindrical outer case (1KtI), cover both ends of the outer case with metal characters 7 (II 14),
The cap (!1141 for each workpiece 1K) < Welding and inserting 9 parts: is automatically Ka by the turntable method as follows.
Can be erected.

A turntable with a plurality of spatulas V arranged at a fixed pitch around the periphery is rotated intermittently at each arrangement pitch of the heads. Insert the spatula FKiN (exterior case) vertically and position it. When this head reaches the next work position, press fit the exterior case (tlKv-black) inside the head.

If this press-fitting of the workpiece is in a short range, it is performed in two stages with one workpiece press-in.In other words, when the press-fitting of the workpiece is completed and the head moves to the next workpiece, there is a leakage (II is press-fitted). 9 External case (!i Supply a cap (set) and cover it, then leak the cap ($1) at the next work position (

The spot fIjI is in constant contact with the upward direction and the point C.Furthermore, when the head comes to the next work position, remove the dark (1) and the outer case from the head and the map (remove the integral part of the button and lower the L). Reverse it and place it on the head again.This reversal work is carried out in several stages with J to J positions.Then, when the head with the turned part comes to the next work position. , supply another cap (4), and then leak cap (4) at the next working position (1) vcI

After arranging the various workpieces, the caps (11

When welding $1 and inverting the iWA product and supplying it to the head, the inner diameter of the head was changed because the outer diameter of the inverted part became too large. It is necessary to place the head near the head that positions the parts before inversion (and so on), and there is a lack of mechanical commonality between the heads, and the turntable becomes a value line and the turntable's thin index. There were problems with the decline.

The present invention was created in view of these problems, and provides a turntable drive method that is effective for turntables that perform KX-like machining on the L bottom, left and right, front and back of a workpiece, etc. This threat will be explained below.

For example, %II/parts shown in the figure (in the case of a turntable used for assembling carp, there are a total of /k heads (aJ k)...(II) 伽) around the periphery as shown in Fig. 2.・Fixed pitch! Using a turntable arranged in ikL, each head (~(Kag... 伽) -ノ・８ is arrayed at a pitch of 10.

When the /ri spatula F (&) comes to the first work position, the work supply I & equipment supplies the lir 9-ku (11).At this time, as shown in @/J- Since the workpiece holder l1a04 is inserted into the mark insertion large 1141 of the head (1), the leakage river is inserted into the hole of the case platform with a larger diameter. When the head (&) enters the working position ν, #C before an interval, the workpiece pusher 5 leaks and the push-down rod (all lowers and inserts the case and connects the sixth mackerel glue (1) to the first As shown in the figure, the leak (1) is pushed into the insertion hole +141.At this point, the leak (1) is accurately positioned.Also, as the workpiece (1) is lowered, the workpiece holder also holds the axis 9mm. The stroke descends.The workpiece push-down rod rises by 1, the turn-chip moves 1 interval in advance, and when the head (&) comes to work position P6, the sub-table descends and the %l Koos Shinjin The case insertion rod of head 4 @4 is inserted into the head (Ko's divinity hole lII). This case insertion rod - Kt-1 has already been press-fitted into the outer case (!1), so the case insertion rod - As the outer case is inserted, an ulcer occurs in the main part of the case of the head (&) as shown in the 1st J cause. It is possible to accurately position the workpiece in the inner circumferential direction.Therefore, the No. 4 pusher rod is raised under the work position, and the workpiece holder is aligned with the shaft as shown in the figure. The leak 11) is pushed through the 0 station into the outer case (!1) inside the case insertion 6, and this pushing force causes the workpiece insertion rod to come out of the outer case.Then, the workpiece When the pushing is completed, the workpiece is pushed away, the rond light descends, the f button pull circle rises by 1, and then the turn key 1 loop moves back to the head (
