Claims

[Claims for Utility Model Registration] In a position indexing device in which a drive motor 21 is driven by a hydraulic pump and this drive motor drives an indexed object 26, a flow rate is applied to a tank line 52 connecting the drive motor 21 and a tank. A control valve 37 is provided, and the flow rate control valve 37 is provided with a spool 50 that opens and closes the variable orifice 36, and the contact 46 of the upper spool 50 is brought into contact with the cam surface of the cam 34 that interlocks with the drive motor 21. By coming into contact with
The spool 50 is slid in accordance with the cam shape, the opening degree of the variable orifice 36 is adjusted, and a recess 41 is formed in the cam surface, and when the contact 46 is fitted into the recess 41, the The variable orifice 36 is closed by the spool 50, and a detachment means is provided to open the variable orifice 36 by detaching the contact 46 from the recess 41. Furthermore, a bypass line 71 is provided to connect the front and rear of the variable orifice 36. Aperture 7 to line 71
1. A position indexing device characterized in that: 2 is interposed.
