Three-laser displacement sensor fixture with convenient and fast angular adjustment

Abstract

The invention discloses a three-laser displacement sensor fixture with convenient and fast angular adjustment. The three-laser displacement sensor fixture with the convenient and fast angular adjustment includes a regular triangular prism positioning piece, three L-shaped fixing pieces, an angular adjustment mechanism, and a fixture flange plate. The angular adjustment mechanism is placed on the L-shaped fixing pieces, and is composed of an angular adjustment screw, an arc-shaped angular adjustment sliding groove, an angular positioning groove, a spring, a sleeve and graduation lines. The regular triangular prism positioning piece can assemble the three L-shaped fixing pieces in the circumferential direction by bolt connection and the fixture flange plate is assembled well by bolt connection so as to match with the tail end of a robot. The three-laser displacement sensor fixture with the convenient and fast angular adjustment can make three laser displacement sensors placed evenly on the circumference of a cutter, can adjust the sensor angles conveniently and quickly under the different requirements of measurement angles and omits the complex process of disassembling the sensors inthe angular adjustment process.

Description

technical field [0001] The invention relates to a fixture, in particular to a three-laser displacement sensor fixture. Background technique [0002] For a large number of workpieces with large spatial dimensions and complex surface shapes, it is often necessary to measure the surface normal direction when processing them. At present, the measurement method based on non-contact laser displacement sensors is widely used. According to different application situations The laser displacement sensor clamping measurement method with different angles should be selected. For example, in the drilling process on the surface of the workpiece, the range of measurement points around the hole-making point to be measured is different under the hole-making requirements of different apertures or the surface of the workpiece with different curvatures. It is necessary to select laser displacement sensors with different angles to measure the normal of the workpiece surface. The vector makes it ...

Problems solved by technology

For example, in the drilling process on the surface of the workpiece, the range of measurement points around the hole-making point to be measured is different under the hole-making requirements of different apertures or the surface of the workpiece with different curvatures. It is necessary to select laser displacement sensors with different angles to measure the normal of the workpiece surface. The vector makes it more accurate. On ordinary fixtures, it is often necessary to disassemble and adjust the sensor and even the fixture when dealing with different hole-making requirements. The cumbersome disassembly steps are time-consuming and labor-intensive, which affects the processing cycle. It will cause wear to the fixture and reduce the accuracy of the sensor or even damage it
