Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 and 2, a fastener hardness testing mechanism may include a testing probe 1, a comparison probe (not shown) and a sorting assembly 2, wherein the testing probe 1 and the comparison probe are annular eddy current probes with the same specification, the testing probe 1 is installed between an upper V-shaped inclined slideway 3 and a lower V-shaped inclined slideway 4 for testing hardness of a fastener (not shown) sliding downwards along the upper V-shaped inclined slideway 3 and passing through the upper V-shaped inclined slideway 3, and the comparison probe is installed outside the upper V-shaped inclined slideway 3 and the lower V-shaped inclined slideway 4 for obtaining standard testing parameters of the fastener. The upper V-shaped ramp 3 is adapted to receive fasteners from a previous process. The sorting assembly 2 is used for sorting the fasteners sliding out of the lower V-shaped inclined slide 4 into an NG bin (not shown) or an OK bin (not shown) according to the detection results of the detection probe and the comparison probe.

In this embodiment, the sorting assembly 2 may include a chute 21, a lever 22, and a drive mechanism, the chute 21 being connected to the lower end of the lower V-shaped inclined ramp 4 so that the inspected fastener can slide from the lower V-shaped inclined ramp 4 into the chute 21. The NG bin is located to the side of the chute 21 and the OK bin is located directly below the lower end (end) of the chute 21. The shifting rod 22 forms a side plate of the sliding chute 21, and the driving mechanism is in driving connection with the shifting rod 22 so as to shift the NG fasteners into the NG storage bin. Specifically, the driving mechanism may include an air cylinder 23, a slide rail 24, a slide block 25, a rack 26, a gear 27, and a rotating shaft 28, the slide rail 24 is mounted on the support under the slide groove 21, the slide block 25 is slidably engaged on the slide rail 24, the rack 26 is fixed on the slide block 25 and is in driving connection with the air cylinder 23, the gear 27 is fixed on the rotating shaft 28 and is engaged with the rack 26, and one end of the shift lever 22 is fixedly connected to the rotating shaft 26. When the hardness of the fastener is detected to be unqualified, the air cylinder 23 drives the rack 26 to move, the gear 24 is driven to rotate, the shifting rod 22 is driven to rotate, and the NG fastener on the sliding groove 21 is shifted into the NG storage bin

Preferably, guide tubes 5 butted with the upper V-shaped inclined slideway 3 and the lower V-shaped inclined slideway 4 are arranged at two ends of the detection probe 1, so that a fastener can penetrate through the middle of the detection probe 1, the detection result is reliable, and no detection is avoided.

Preferably, the contrast probe is placed horizontally to facilitate the inspection operation.

Preferably, the angle of inclination of the upper V-shaped ramp 3 and the lower V-shaped ramp 4 is around 30 degrees. This ensures on the one hand that the fastener can glide smoothly and on the other hand that the glide speed is not too fast, avoiding damaging.

The working principle of the present invention is briefly described as follows: firstly, placing a qualified fastener in a comparison probe, then starting detection, enabling the fastener from the previous process to enter an upper V-shaped inclined slideway 3 and slide down along the upper V-shaped inclined slideway 3 to pass through a detection probe 1 to perform shape hardness detection; if the hardness detection is not qualified, the air cylinder 23 acts to drive the shifting rod 22 to shift the NG fastener on the sliding chute 21 into the NG storage bin; otherwise the fastener slides down the chute 21 into the OK magazine. The whole detection process basically does not need manual intervention, so that the labor cost is greatly saved, and the production efficiency is obviously improved.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
