Description

Technical Field

[0001] The invention relates to a saw blade detection device, and more particularly to a circular saw blade cutter head detection device. Background Art

[0002] In the production process of circular saw blades, the grinding quality inspection process of all blades after the saw blades are ground is particularly important. Conventional process inspection methods generally use dial indicators, projectors, advanced scale magnifiers, microscopes and other equipment to inspect the dimensions and grinding quality of all blades one by one according to the corresponding CAD drawings of the saw blades, and then record the test results in the inspection table. This process inspection method has a very low inspection efficiency. Different inspection contents require different personnel to be divided into different inspections, which requires a large number of workers. At the same time, due to the differences in the results of inspections by different personnel, it is easy to form bad misjudgments, and even bad products are shipped to customers. In addition, there will be measurement errors between the inspection equipment and instruments, resulting in inaccurate measurement results and inability to accurately judge the qualified product size. In addition, when checking the grinding quality of the blade head, due to the small size of the blade head, some minor defects cannot be discovered in time, including some small tip loss and small chipping of the blade head, which has a great impact on the cutting quality of the saw blade. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings, the present invention provides a circular saw blade cutter head detection device, which can realize the detection of the circular saw blade cutter head with accurate and reliable detection and high detection efficiency.

[0005] During the circular saw blade head inspection operation, the saw blade to be tested is loaded onto the saw blade rotating assembly, which can drive the saw blade to be tested to rotate.

The lower detection camera takes an image of the lower surface of the saw blade head to be tested, and collects data such as the lower side edge, contour, texture, and size of the blade head. The side detection camera takes an image of the side of the saw blade head to be tested, and collects data such as the top edge, contour, texture, and size of the blade head tip. By comparing and analyzing the collected image information, the blade head is inspected to determine whether it is qualified. The saw blade to be tested rotates one circle to complete the inspection of the blade head at each position of the edge of the saw blade to be tested. The inspection of the blade head data is completed by comparing and analyzing the images taken by the detection camera, which is more convenient than manual inspection, and all data can be inspected in one process, avoiding the accumulation of errors caused by using multiple inspection equipment. The entire inspection process is completed automatically and does not rely on the experience of the inspector.

At this time, a gap is left between the outer wall of the positioning clamp and the inner wall of the through hole, which is convenient for the installation of the saw blade to be tested. After the saw blade to be tested is loaded into the loading seat, the driving rod moves, and the positioning clamp is pushed radially outward through the connecting rod, so that the positioning clamp is tightly clamped to the inner wall of the through hole of the saw blade to be tested, so as to realize reliable positioning of the saw blade to be tested.
