no. 1 Embodiment approach &g

[0019]

[0020] By dividing the support into a plurality of members, the distance between the rotation axis and the base can be adjusted to suit the size and shape of the workpiece. In the first embodiment, a workpiece positioner provided with a column having a split structure will be described.

[0021] figure 1 It is a schematic front view of the workpiece positioner 100 of the first embodiment. refer to figure 1 , the workpiece positioner 100 will be described.

[0022] The workpiece positioner 100 includes a workpiece holding portion 110 , a driving portion 120 , a bearing portion 130 , a base 140 , a first support 150 , and a second support 160 . The workpiece holding portion 110 is used to hold a workpiece (not shown). The workpiece holding part 110 is arranged in the space between the driving part 120 (and the first support 150 ) and the bearing part 130 (and the second support 160 ). In the present embodiment, the first workpiece is exemplified by the workpiece ...

Abstract

The invention provides a workpiece positioner. The workpiece positioner includes: a first workpiece holding part, which holds a first workpiece; a first drive part, which outputs a first torque around a first rotation axis, and imparts a first torque around the first rotation axis to the first workpiece holding part. Angular movement; bearing part, which cooperates with the first driving part to support the first workpiece holding part; base, which is arranged at a position separated from the first rotation axis; A first support axis extending from the rotation axis extends to support the first driving part; a second support extends between the base and the first rotation axis along a second support axis extending parallel to the first support axis to support the bearing department. The first support includes a plurality of first support pieces arranged along the first support axis.

Description

technical field [0001] The present invention relates to a workpiece positioner for setting a workpiece to be processed at an appropriate position and an appropriate posture. Background technique [0002] The workpiece positioner is used to set a workpiece to be processed in an appropriate position and in an appropriate posture (refer to Japanese Patent Laid-Open No. 8-47880). Since the workpiece is held at an appropriate position and an appropriate posture with respect to the tool by the workpiece positioner, the workpiece is precisely machined. [0003] Conventional workpiece positioners are designed to suit the shape and size of the workpiece to be machined. Therefore, if there are a plurality of workpieces with different shapes and sizes, a plurality of workpiece positioners suitable for these workpieces are required. This means that a lot of design work for the workpiece positioner is required. [0004] There are also workpiece positioners that are designed in such a ...
