Problems solved by technology

[0004] Aiming at the problems existing in the existing laser measurement technology for spiral bevel gears, the present invention provides a laser displacement sensor system with multiple degrees of freedom and a measurement method for spiral bevel gears, so as to solve the problems caused by spot light sources on the tooth surface to be measured. The reflected light is blocked by the unmeasured tooth surface and cannot be reflected to the receiving window of the sensor, resulting in the loss of data collection points on one side of the tooth surface

Embodiment Construction

[0029] Such as figure 1 Shown is a multi-degree-of-freedom laser displacement sensor system proposed by the present invention, which includes a base 1 , a slewing frame 2 , a rotating platform 3 , a quick clamping table 4 , and a locking knob 5 . The base 1 is provided with a slewing frame 2 concentric with the central axis I axis through a rotating mechanism. The slewing frame 2 can freely rotate 360° relative to the base 1 around the central axis I axis of the base 1. The pose of the slewing frame 2 relative to the base 1 It can be fixed by the locking knob of the base 1. The rotary frame 2 is provided with a rotary platform 3 through a rotary mechanism, and the rotary platform 3 can freely rotate 180° relative to the rotary frame along the II axis. 4. The quick clamping table 4 can clamp the laser displacement sensor 6 through the pressing plate and the locking knob 5 .

Abstract

The invention relates to the technical field of gear measurement, in particular to a structure of a multi-freedom degree laser displacement sensor system and a spiral bevel gear measurement method of a device based on the measurement system. The system consists of a laser displacement sensor and a support with the spatial orthogonal axial rotational freedom degree. During measurement of the spiral bevel gear, the rotational pose of the sensor support can be adjusted to allow the laser displacement sensor to keep the same spatial inclined pose with the to-be-measured arc-shaped tooth line as far as possible, thereby ensuring that light spot light sources on the to-be-measured gear tooth face irradiated by laser emitted by the sensor can be reflected on a receiving window of the sensor. Thus, in a measurement process of the gear, acquired data is complete and effective. The system and the method are characterized by simple measurement equipment structure, easy operation and high flexibility.

Description

technical field [0001] The invention relates to the technical field of gear detection, in particular to a laser displacement sensor system with multiple degrees of freedom and a method for measuring spiral bevel gears. Background technique [0002] Gear measurement technology can be divided into two categories: contact measurement and non-contact measurement. At present, the contact measurement method that touches the three-dimensional coordinate position of the surface point of the geometric shape of the measured part through the trigger or scanning sensor measuring head is widely used. . This method needs to ensure that the probe is always in close contact with the surface of the measured part during the measurement process. Due to the existence of the radius of the spherical contact of the probe, the measurement of parts with complex curved surfaces will have the problem of low horizontal resolution, and the actual contact measurement There is a difference between the co...
