[0001] The present invention belongs to the technical field of cam processing, and relates to a precision detection device, in particular to a precision detection device for cam processing. Background Art

[0002] A cam is a mechanical part with a curved profile or groove, usually used to convert rotational motion into reciprocating motion or achieve a specific motion trajectory, and has a wide range of applications in various mechanical devices. In modern manufacturing, quality control is a key link to ensure product quality and production efficiency. Precision detection of such key components as cams is carried out to ensure the consistency and stability of product quality. However, existing cam detection often relies on manual operation, which requires a high professional level and has a low automation level, making it difficult to meet the requirements of industrial production.

[0003] Therefore, we propose a precision detection device for cam processing, which can perform automated operations such as positioning and conveying of cams, accurate clamping and handling, detection and fixing, automatic detection, and classification and output, with low professional level requirements, and is convenient and efficient. Summary of the Invention

A detection mechanism, a rotating table, a classification and output mechanism, and a handling mechanism are provided at the upper end of the detection frame. The rotating table is located at the middle position of the upper end of the detection frame. An inner support and fixing mechanism is provided at the middle position inside the rotating table. The detection mechanism is located on the left side of the rotating table, the classification and output mechanism is located at the rear side of the rotating table, the handling mechanism is located on the right side of the rotating table, and the conveying direction of the handling mechanism is perpendicular to that of the classification and output mechanism. The two conveyors I are respectively located on the left and right sides of the detection frame, and both the two conveyors I are located below the classification and output mechanism. A conveyor II is provided at the front side of the detection frame. A number of cam fixing mechanisms are evenly distributed at equal intervals on the conveyor II, and the conveyor II is located below the handling mechanism.

[0007] The working principle of the present invention is as follows: Input the design parameters of the machined cam in the cloud. The staff place the cams to be inspected on the cam fixing mechanism in sequence. When placing, the cam fixing mechanism adjusts the position of the cam to be inspected to position it. The conveyor two drives the cam fixing mechanism and the cams to be inspected thereon to move under the handling mechanism. The handling mechanism moves directly above the cam to be inspected, and then moves downward to clamp the cam to be inspected. Subsequently, it moves upward to transport the cam to be inspected above the rotating table, so that the shaft hole of the cam to be inspected is located at the specified position. Then, it pauses. The detection mechanism moves under the shaft hole of the cam to be inspected, adjusts its position, and then detects the accuracy of the shaft hole of the cam to be inspected. After the detection is completed, the detection mechanism returns to the initial position. The handling mechanism moves downward to place the cam to be inspected on the rotating table and then returns to the initial position. The inner support fixing mechanism moves upward and extends into the shaft hole of the cam to be inspected. The inner support fixing mechanism moves to support the shaft hole of the cam to be inspected to fix the cam. Subsequently, the rotating table drives the cam to be inspected to rotate forward and backward in an alternating manner for one full circle. Then, the detection mechanism moves and adjusts its position to measure the contour accuracy of the cam to be inspected. The test data is uploaded to the cloud and compared with the design parameters to classify the cams to be inspected. The inspected cams are divided into qualified cams and unqualified cams;

[0008] After the test is completed, the rotating table stops moving, and the inner support fixing mechanism returns to the initial position. The classification and output mechanism moves above the inspected cams, then moves downward to clamp the inspected cams, and transports the inspected cams to the conveyors one on the left and right according to the detection results.
