[0001] This utility model belongs to the field of nut processing technology, specifically, it relates to a nut processing positioning device. Background Technology

[0002] A nut is a fastener that is screwed onto a bolt or threaded rod to provide a fastening function. During the machining of the internal thread of a nut, a positioning device is required to fix it in place.

Under prolonged high-intensity working conditions, operators are prone to fatigue, leading to untimely or inaccurate unloading, and may even cause damage or loss of the nut. Furthermore, existing nut positioning devices lack a structure to limit the top of the nut, causing the nut to wobble during thread processing, thus affecting machining accuracy. Therefore, we propose a nut machining positioning device. Summary of the Invention

[0027] By setting up a flange, it is easy for personnel to disassemble and replace the positioning and processing plate 3, so that nuts of different specifications can be processed.

[0028] Furthermore, the limiting assembly includes an L-shaped limiting plate 8 and an adjusting plate 9. The L-shaped limiting plate 8 is snapped onto the top of the positioning processing plate 3. The L-shaped limiting plate 8 and the adjusting plate 9 are slidably connected at one end. A shrinkage groove 10 is provided on the back of the support platform 1.

[0033] The guide plate 25 can serve as a buffer and guide for the nut.

[0034] The implementation principle of a nut processing positioning device is as follows: A positioning processing plate with a nut placement slot of the corresponding specification is mounted on a rotating shaft and a support table via a flange. Nuts requiring internal thread processing are placed into the nut placement slot of the positioning processing plate. Fastening bolts one and two are loosened. Then, the position of the L-shaped limiting plate at the top of the positioning processing plate is adjusted to accommodate the corresponding nut specification. Fastening bolts one and two are then tightened to fix the L-shaped limiting plate. The motor is then started via a controller, driving the rotating shaft to rotate. The rotating shaft, through a connecting shaft, drives the positioning processing plate to rotate, causing the positioning processing plate to move the nut in the nut placement slot to below the L-shaped limiting plate, allowing the L-shaped limiting plate to limit the nut. The nut is then threaded using a thread processing device. After processing, the motor is started again, causing the positioning processing plate to move the next nut in the nut placement slot to below the L-shaped limiting plate. Nuts are processed sequentially. When the processed nut moves... When the block reaches below the L-shaped fixing plate, it contacts the contact switch. The contact switch sends a signal to the controller, causing the controller to extend the electric cylinder. The electric cylinder drives the pressure frame downward, pressing the nut out of the nut placement slot. The finished nut then falls through the drain hole into the collection box, automatically completing the nut unloading process. Personnel can then directly place new nuts into the unloaded nut placement slot, improving processing efficiency. This structure automatically presses the finished nuts out of the nut placement slot, completing the unloading process, improving efficiency, saving manpower, and thus increasing nut processing efficiency. Furthermore, by setting a limit component, the top of nuts of different specifications can be limited during processing, improving stability and ensuring processing accuracy. The ball bearings and grooves provide support for the positioning processing plate and reduce friction between the positioning processing plate and the support table, ensuring the stability and flexibility of the positioning processing plate during rotation.
