Problems solved by technology

However, in the case where the jig itself rotates as described above, since the rotation mechanism is included, it is difficult to arrange the oil pressure pipes, and installation and maintenance are costly.
[0007] In addition, liquid leakage of working oil is likely to occur at the parts joined by the above-mentioned hydraulic joints, etc.
Therefore, there is a possibility of failure, reduced reliability

Abstract

The invention relates to a locating device which is provided with a clamp and a supercharger. The clamp comprises a driving component and a fixing mechanism, wherein the driving component receives pressure supply to conduct driving, and the fixing mechanism is driven by the driving component and enables a workpiece serving as a machined object to be fixed at the specific position. The supercharger is arranged on the clamp and used for supercharging the pressure supplied to the driving component. In addition, the clamp enables the workpiece to be preliminarily fixed on the fixing mechanism based on a first pressure supplied by the outside, and the workpiece is formally fixed on the fixing mechanism based on a second pressure obtained by supercharging the first pressure through the supercharger.

Description

technical field [0001] The invention relates to a positioning device and a robot system equipped with the positioning device. Background technique [0002] Conventionally, there is known a positioning device that holds a workpiece to be processed at a predetermined position with a jig or the like. In addition, there is also proposed a positioning device capable of orienting the workpiece in a predetermined direction by, for example, rotating the jig itself that holds the workpiece (for example, refer to Japanese Patent Application Laid-Open No. 5-177391). [0003] Such a positioning device is equipped, for example, in a robot system, and is used for positioning a workpiece when a robot performs predetermined processing such as welding. [0004] In addition, when such a robot performs a predetermined machining operation, the positioning device is required to position the workpiece with high precision. Therefore, the structure of the jig holding the workpiece includes a fixi...
