The invention discloses a rapid detection device for caliper internal channel defects. The device comprises a workbench, a lifting mechanism, an image collection mechanism, a bearing mechanism and an image display mechanism. The lifting mechanism comprises a vertically-arranged screw rod and a lifting block. A supporting arm is installed at the front end of the lifting block. The image collection mechanism comprises an industrial camera. The lens of the industrial camera is vertical downwards. A light source is installed below a right-angle installation frame. A prism suspension is further arranged. A total reflection prism is installed at the bottom end. The bearing mechanism comprises a base. A rotary table is installed on the base. A sliding table is installed on the surface of the rotary table. A caliper jig for fixing a caliper sample piece is arranged on the upper surface of the sliding table. The image display mechanism comprises a display for image display. A three-dimensional annular image is converted into an annular plane image by adopting prismatic refraction, surface features of an internal channel can be seen clearly through the magnified annular image, defect detection is performed, and the rapid detection device has the advantages of being high in working efficiency, accurate in judgment and the like, and is suitable for large assembly line assembly operation.
Description
technical field [0001] The invention belongs to the field of automobile manufacturing, and relates to an automatic detection device, in particular to a rapid detection device for groove defects in a caliper. Background technique [0002] The quality of the caliper is the key to determine the quality of the car's braking performance and the safety of the car. In the machining and manufacturing industry, due to the characteristics of the material itself and the influence of the processing process, the calipers will have various defects such as blisters and vibration lines. These defects will damage the sealing performance of the calipers and cause the performance of the braking system to fail. Thereby causing the safety hazard of automobile. At the same time, the accuracy and life of the equipment will be reduced. However, the defect detection of the groove in the caliper requires high technical requirements. At present, domestic detection of groove defects in calipers ma...
