Problems solved by technology

[0003] At present, the existing equipment for shaft parts detection in manufacturing enterprises mainly has two problems. One is that due to the poor degree of automation and the limitation of use conditions, the detection efficiency is low, and most of them are used in sampling surveys and small batches. Realize large-scale application and real-time online detection on the production site. Second, the detection equipment has a single function and is expensive, and cannot realize large-scale part performance testing

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with specific examples, and methods not described in detail in the present invention are all prior art.

[0014] Such as figure 1 As shown, the multi-station, multi-parameter and high-precision measuring device for light curtain type shaft parts includes an electromechanical body and four measuring head devices, such as figure 2 As shown, the probe device includes a support base 4 with slide rails, a slit LED parallel light source 3 and two linear array CCD cameras 8. The slit parallel LED light source 3 changes in sinusoidal regular brightness under computer control, and the slit LED parallel light source 3. The green parallel light with low divergence angle is generated, and the upper and lower edges of the light spot are blocked by the shaft part 2 to be measured and collected by two linear array CCD cameras 8. The irradiation direction of the slit LED parallel light source 3 is the same as that ...

Abstract

The invention discloses a multistation and multiparameter high precision measurement device of a light curtain shaft part, which comprises an electromechanical body and four measurement head devices, wherein each measurement head device comprises a support base (4) with a slide rail, slit LED (Light-emitting Diode) parallel light source and two linear array CCD (Charge Coupled Device) cameras (8); the brightness of the slit LED parallel light sources (3) is changed sinusoidally and regularly under the control of a computer; the slit LED parallel light sources (3) generate green parallel light with a low divergence angle; and the upper and lower edges of light spots generated due to the fact the parallel light is shielded by the shaft part (2) to be measured are acquired by the linear array CCD cameras (8). Since double CCD sensor probes measure the upper and lower edges, the measurement range is extended, and the measurement precision is improved. Due to multistation synchronous measurement, the measurement course is accelerated, and the requirement on a service environment is lowered.

Description

technical field [0001] The invention relates to the detection, storage and analysis of the diameter, taper, roundness and shape line of shaft parts, and can be applied to parameter detection and quality control of shaft parts in the fields of automobiles, motorcycles, machine tools and the like. Background technique [0002] The integration and integration of measurement and processing has become one of the new development trends of modern manufacturing technology. Comprehensive quality inspection and control, real-time inspection of processing process and product performance indicators, 100% inspection of product (part) parameters are the basis for ensuring product quality, realizing "zero waste manufacturing" and realizing product quality problem traceability. [0003] At present, the existing equipment for shaft parts detection in manufacturing enterprises mainly has two problems. One is that due to the poor degree of automation and the limitation of use conditions, the d...
