Description

Technical Field

[0001] This invention relates to the field of shaft workpiece inspection technology, and in particular to a shaft workpiece transportation inspection device. Background Technology

[0002] Shafts, also known as shaft parts, are key components in mechanical transmission systems and are widely used in various fields such as automotive, aerospace, and machinery manufacturing. The quality of shaft parts directly affects the performance, reliability, and service life of the entire mechanical system. Therefore, precise inspection of parameters such as dimensional accuracy and surface appearance is required during the production of shaft parts.

[0003] In existing technologies, to meet the demands of mass production, the inspection of shaft-type workpieces typically requires automated inspection equipment. This equipment uses delivery components to sequentially feed each shaft-type workpiece to various stations on a support frame for inspection. For example, Chinese invention patent CN122259595A discloses a motor shaft appearance inspection device, which includes a feeding mechanism, a conveying mechanism, a first end face inspection mechanism, a second end face inspection mechanism, and an outer peripheral surface inspection mechanism. The conveying mechanism's advancing component is equipped with a delivery cylinder and a lifting cylinder. However, in practical use, the existing inspection devices require the advancing cylinder and lifting cylinder to operate sequentially according to a predetermined time sequence. The consistency of their coordination is difficult to guarantee, easily leading to misalignment of the shaft-type workpieces during movement. This necessitates operators stopping the machine to adjust the workpiece's position, resulting in inefficient and disruptive inspection processes. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by designing a shaft-type workpiece transport and inspection device. The progressive drive component only requires one progressive motor as a power source to realize the synchronous circumferential and lifting movements of each progressive clamping mechanism, resulting in good motion consistency. This ensures stable and smooth inspection of shaft-type workpieces and improves inspection efficiency.

The progressive frame 321 is mounted on the frame 1. The progressive motor 322 and the track plate 324 are both mounted on the progressive frame 321. The progressive motor 322 is a rotary motor. One end of the transmission arm 323 is fixedly connected to the rotating shaft of the progressive motor 322. The other end of the transmission arm 323 is movably connected to a transmission wheel 307. A groove 308 extending along the length of the transmission arm 323 passes through the other end of the transmission arm 323. One side of the transmission wheel 307 is slidably connected to the groove 308, allowing the rotating wheel to slide along the length of the transmission arm 323. The transmission wheel 307 is pivotally connected to the transmission plate 325.

A constraint plate 326 is slidably mounted on a conveyor frame 321 along a first direction, the length direction of the conveyor frame 321. A first linear slide rail 306 extending along the length direction is fixedly connected to the conveyor frame 321. The constraint plate 326 is slidably connected to the first linear slide rail 306, causing the constraint plate 326 to slide horizontally back and forth relative to the conveyor frame 321 along the first direction. A transmission plate 325 is slidably mounted on the constraint plate 326 along a second direction, the height direction of the transmission plate 325. The upper part of the transmission plate 325 includes a second linear slide rail 313 extending along its height direction. The constraint plate 326 is slidably connected to the second linear slide rail 313, causing the transmission plate 325 to slide up and down back and forth relative to the constraint plate 326 along the second direction.

[0031] refer to Figures 1 to 17 In use, the inspection equipment utilizes the coordination of the constraint plate 326, transmission plate 325, track plate 324, and transmission arm 323. The progressive motor 322 drives the progressive plate 327 and each progressive clamping mechanism 328 to synchronously perform circular and lifting movements, thereby achieving progressive transport of the shaft workpiece 12. The shaft workpiece 12 is transported from the feeding device 2 to the conveying device 3 and sequentially passes through each vision inspection component. Afterward, the shaft workpiece 12 is transported to the sorting and unloading device 5 for sorting and unloading. During the progressive transport of the shaft workpiece 12, the progressive clamping mechanism 328... When the shaft workpiece 12 is lifted, it is clamped and disengaged from the two corresponding support stations 301. When the shaft workpiece 12 is lowered, it is released and aligned with the two support stations 301. This ensures that the shaft workpiece 12 is subjected to stable force during handling and unloading, and avoids the shaft workpiece 12 from shifting. The progressive drive assembly 32 only needs one progressive motor 322 as a power source to realize the synchronous circumferential and lifting movements of each progressive clamping mechanism 328.

The diameter-length docking end 1101 and the sensing end of the diameter-length stroke sensor 115305 abut against the end of the shaft workpiece 12 to detect its diameter-length. The diameter-length detection table 111 is slotted to the diameter-length alignment part 1102 for the diameter-length alignment part 1102 to be inserted, thereby realizing the pre-positioning of the diameter-length detection pressure plate 114 and ensuring the accuracy of the diameter-length detection result.

The material channel structure 102 is provided with through holes through which the upper two ends of the placement frame 104 pass. When the shaft workpiece 12 moves to the discharge side of the sorting and discharging device 5, the shaft workpiece 12 is supported at the upper two ends of the placement frame 104. According to the detection result of the shaft workpiece 12, the placement lifting mechanism 103 retracts so that the shaft workpiece 12 falls into the corresponding sorting and collection box 54 along the inclined surface of the material channel structure 102. Alternatively, the position of the sorting clamping mechanism 53 is adjusted by the sorting translation mechanism 51 and the sorting lifting mechanism 52 so that the shaft workpiece 12 supported at the upper two ends of the placement frame 104 is transported to other material channel structures 102, thereby realizing sorting and discharging collection.

[0036] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
