Description

Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing, and in particular to an automatic tapping detection device. Background Art

[0002] When traditional tapping equipment processes threaded holes in a workpiece, the tapping equipment controls the tap to move vertically from top to bottom so as to tap the workpiece that is positioned and clamped on a horizontal working platform. Since traditional tapping equipment can only control the vertical movement of the tap, when the workpiece is long and needs to be processed in rows of threaded holes on the long side, the tapping equipment controls the tap to control each processing frequency. The operator needs to push the workpiece horizontally until the tap is aligned with the next position to be tapped on the workpiece, and then repositions and clamps the workpiece. The tapping equipment controls the tap to perform the next processing frequency. Therefore, during the processing, the workpiece needs to be clamped and positioned multiple times, which greatly reduces the processing efficiency. At the same time, multiple clamping and positioning of the workpiece will also cause cumulative positioning errors, affecting the processing accuracy. Moreover, since the workpiece to be processed is large, at least two operators are often required to complete the movement and positioning of the workpiece. Therefore, the labor cost is relatively high, and the overall production cost is not high. In addition, the tapping tool needs to be inspected before each tapping, which affects the production rhythm. The tapping requirements on the same product are different, such as through holes or blind holes. Figure 1 As shown, blind holes are tapped at positions a, b, c, and d, and through holes are tapped at positions e, f, and g. It is necessary to switch the tapping equipment. Based on the above defects and shortcomings, it is necessary to improve the existing technology and design an automatic tapping detection device. Summary of the invention

[0041] When the automatic tapping detection device of the present invention is working, the products in the housing vibrating tray 21 are conveyed to the product installation groove 250 of the bearing module 25 through the guide block 22. When the in-place sensor 26 detects the product, the misalignment cylinder 24 drives the bearing module 25 to move, and the guide block 22 and the bearing module 25 are misaligned, enabling misaligned feeding to avoid product accumulation. The transposition manipulator 27 grabs the product in the product installation groove 250 and places it on the carrier block 283 and the stock preparation block 287. The telescopic rod of the pen-shaped cylinder 284 extends to drive the carrier block 283 to move, and the slide table cylinder 286 drives the stock preparation block 287 to move above the linear slide rail 282. The pen-shaped cylinder 284 and the slide table cylinder 286 cooperate to adjust the relative distance between the carrier block 283 and the stock preparation block 287 for subsequent dual-station feeding. The lead screw handling module 31 works, and the upper and lower handling components 317 suck two products. The servo motor 315 drives the lead screw 314 to rotate, thereby driving the transfer plate 313 to move along the direction of the transfer linear slide rail 312. When the two products sucked by the upper and lower handling components 317 move in front of the product carrier 42 of the blind hole tapping detection mechanism 4, the servo motor 315 pauses, and the upper and lower handling components 317 place the sucked two products into the product carrier 42. At this time, the pressing component 43 works. The pressing cylinder 431 drives the four pressing plates 433 on the pressing push plate 432, and the pressing plates 433 move downward. The pressing bumps 4330 of the pressing plates 433 press on the product groove. The tapping device 44 moves downward to tap a blind hole at position a on the product. The detection push-pull cylinder 452 drives the detection push plate 453 to move forward. If tapping is in progress at the tapping device 44, the detection push block 455 touches the tap, and the buffer spring 458 is in a compressed state. If the detection push block 455 does not touch the tap, the buffer spring 458 is in an extended state. At this time, the tap cannot be detected, and the machine needs to be shut down for maintenance. After tapping is completed, the lead screw handling module 31 continues to work to move the product to the next station, repeating the above steps to tap the product at positions b, c, and d. After the blind hole tapping is completed, the lead screw handling module 31 drives the follow-up handling module 32 to move through the double ball bearing 34. The variable-distance handling component 324 on the follow-up handling module 32 sucks the products in the two product carriers 42. The telescopic rods of the two variable-distance pen-shaped cylinders 3245 extend to drive the variable-distance push plate 3247 to move, thereby adjusting the distance between the products on the two variable-distance suction cups 3248 to be consistent with the distance between the two through-hole tapping detection mechanisms 5. The variable-distance handling component 324 moves the two products to the through-hole tapping detection mechanism 5. The through-hole tapping detection mechanism 5 performs through-hole tapping on the product at position e. The follow-up upper and lower handling components 325 sequentially move the products to the next station to perform through-hole tapping on the products at positions f and g respectively. After tapping is completed, the follow-up upper and lower handling components 325 transport the products to the belt conveyor 62 of the finished product recycling device 6, and the products on the belt conveyor 62 slide down through the blanking chute 63 into the finished product box 64.
