[0003] The anti-loosening nut includes a nut body, a cap and a washer. A threaded hole is provided on the nut body, and a placement groove is provided on the nut body. The washer and the cap are both located in the placement groove. The cap is located on the side of the washer away from the bottom wall of the placement groove. The nut body and the washer are pressed together by a pressing device, and the nut body and the cap are pressed together by a pressing device to achieve assembly.

[0004] The staff needs to take out the nut body and the washer in turn, then pre-fix the washer in the nut body, and finally move the nut body to the pressing device to realize the pressing process of the nut body and the washer, which results in a slower assembly speed of the nut body and the washer, affecting the work of the pressing device and reducing the production speed of the anti-loosening nut. Summary of the invention

[0005] In order to improve the problem of assembling a washer and a nut body, the present application provides a press-fitting device for assembling a locking nut.

[0006] The present application provides a locking nut and a processing technology thereof, which adopts the following technical solutions: A pressing device for assembling anti-loosening nuts comprises a loading module, a rotating module and a pressing module, wherein the loading module drives the nut body and the washer to move into the rotating module, and the pressing module drives the washer and the nut body to be pressed, and the rotating module comprises a second rotating plate and a mounting seat, wherein the second rotating plate is rotatably connected to the mounting seat, and a second groove for placing the nut body is formed on the second rotating plate, and a blanking strip is provided on the mounting seat, and the blanking strip is located on the rotation path of the second groove; when the nut body abuts against the blanking strip, the nut body disengages from the second groove.

[0007] By adopting the above technical scheme, the nut body is driven to move into the second groove of the second rotating plate through the loading module, and the staff manually places the washer in the placement groove, and with the rotation of the second rotating plate, the nut body is moved to the pressing module, and the pressing module presses the nut body and the washer, and then with the rotation of the second rotating plate, the nut body is abutted against the blanking strip, and the nut body is moved along the length direction of the blanking strip to realize the detachment of the nut body from the second groove and the blanking of the nut body, thereby realizing the semi-automatic assembly of the nut body and the washer. The staff does not need to manually move the nut body, and the staff only needs to install the washer on the nut body, thereby speeding up the assembly speed of the nut body and the washer, and further speeding up the production speed of anti-loosening nuts.

[0008] Optionally, the rotating module also includes a first rotating plate, which is rotatably connected to the mounting seat, and the first rotating plate is provided with a first through-hole for placing the nut body, and the mounting seat is provided with a mounting plate for blocking the first through-hole, and the mounting plate is located between the first rotating plate and the second rotating plate, and the mounting plate is provided with a second through-hole for the washer to pass through; when the first through-hole is aligned with the second through-hole, the washer falls into the placement groove.

[0009] By adopting the above technical solution, the nut body is driven to move into the second groove of the second rotating plate through the loading module, and the washer is driven to move into the first through-hole of the first rotating plate, and then the first rotating plate is rotated on the mounting seat until the first through-hole is aligned with the second through-hole, so that the washer can fall from the first through-hole through the second through-hole into the second groove, at which time the washer can fall into the placement groove of the nut body, realizing automatic assembly of the washer and the nut body, and finally the pressing module presses the washer and the nut body to realize fully automated installation of the washer and the nut body; by locating the mounting plate between the first rotating plate and the second rotating plate, the mounting plate can limit the washer from falling directly from the first through-hole, and only when the first through-hole and the second through-hole are aligned can the washer be separated from the first rotating plate, so that the falling range of the washer is fixed, reducing the possibility of separation of the washer and the nut body.

[0010] Optionally, the mounting plate is provided with a plurality of second through holes, and the diameters of the plurality of second through holes are different. The mounting plate is rotatably connected to the mounting seat, a limiting plate is fixedly connected to the mounting seat, a third through hole for a gasket to pass through is provided on the limiting plate, the limiting plate is located between the first rotating plate and the mounting plate, and the first rotating plate is detachably connected to the mounting seat.

[0011] By adopting the above technical solution, the staff rotates the mounting plate to align the second perforations of different diameters with the third perforations, so that the gasket can pass through the third perforations and the second perforations in sequence from the first perforation, and the gasket falls into the placement groove; by rotating the mounting plate, the diameter of the second perforation can be adjusted, so that gaskets of different diameters can fall from the second perforations, and because the limiting plate is located between the first rotating plate and the mounting plate, the gasket cannot be detached from the second perforations of other diameters, and the first rotating plate is detachably connected to the mounting seat, allowing the first rotating plate to be replaced, so that gaskets of different diameters can fall into the first perforations, so that the rotating module can assemble nuts of different diameters, thereby increasing the adaptability of the rotating module.

[0012] Optionally, a fixing groove is provided on the first rotating plate, a mounting rod is provided on the mounting seat, a fixing strip for inserting into the fixing groove is slidably connected to the mounting rod, and a fastener for limiting the movement of the fixing strip is provided on the first rotating plate; when the fixing strip is inserted into the fixing groove, the fixing strip drives the first rotating plate to rotate.

[0013] By adopting the above technical solution, the staff slides the fixing strip and inserts the fixing strip into the fixing groove to realize the mutual fixation of the mounting rod and the first rotating plate, and at this time the first rotating plate realizes the rotation on the mounting seat; the fixing strip is limited by the fastener so that the fixing strip can be stably located in the fixing groove, and at this time the first rotating plate is not easy to slide on the mounting rod; because the first rotating plate is sleeved on the mounting rod, centrifugal force is generated when the mounting rod rotates, and the fixing strip moves toward the direction of the fixing groove, so that the fixing strip can be stably located in the fixing groove.

[0014] Optionally, a card slot is provided on the first rotating plate, the card slot surrounds along the circumference of the mounting rod, a card strip is slidably connected in the card slot, the mounting plate is rotatably connected to the mounting rod, a movable bar is slidably connected to the mounting plate, a movable slot for inserting the movable bar is provided on the mounting rod, the movable slot extends around the circumference of the mounting rod, and the movable bar is located on the insertion path of the card strip; when the card strip is inserted into the card slot, the movable bar is inserted into the movable slot, and at this time the mounting plate is fixed to the mounting rod.

[0015] By adopting the above technical solution, the staff installs the first rotating plate and inserts the card strip into the card slot. Since the moving strip is located on the insertion path of the card strip, the card strip drives the moving strip to move, so that the moving strip can be smoothly inserted into the moving slot. In addition, the moving slot extends circumferentially around the mounting rod, so that the moving strip can slide in the moving slot. At this time, the moving strip can limit the mounting plate to prevent the mounting plate from rotating on the mounting rod, so that the position of the second perforation can be fixed, reducing the second perforation due to the rotation of the mounting plate. The second perforation cannot be aligned with the second groove in the second rotating plate, thereby increasing the stability of the gasket falling.

[0016] Optionally, an elastic member is slidably connected to the mounting rod, one end of the elastic member is located on the moving path of the fixed bar, and the other end of the elastic member is located on the insertion path of the moving bar; when the moving bar is inserted into the moving groove, the fixed bar is inserted into the fixed groove.

[0017] By adopting the above technical solution, the elastic member is slidably connected to the mounting rod, and when the moving bar is inserted into the moving groove, the moving bar drives the elastic member to move, and the elastic member drives the fixed bar to move, so that the fixed bar is inserted into the fixed groove. At this time, the fixed bar can limit the movement of the fixed bar, so that the fixed bar can be stably located in the fixed groove, reducing the possibility of the fixed bar detaching from the fixed groove, and realizing the mutual fixation of the first rotating plate and the mounting rod; because the elastic member is elastic, the staff can directly slide the fixed bar, so that the fixed bar drives the elastic member to move, so that the first rotating plate can separate from the mounting rod.

[0018] Optionally, the fastener includes a mounting cover, which is detachably connected to the mounting rod and is located on a side of the first rotating plate away from the mounting plate; when the mounting cover is fixed to the mounting rod, the mounting cover abuts against the first rotating plate.

[0019] By adopting the above technical solution, the mounting cover is installed on the mounting rod, so that the mounting cover abuts the first rotating plate, and the mounting cover limits the movement of the first rotating plate, so that the first rotating plate can be stably located on the mounting rod, avoiding the first rotating plate from detaching from the mounting rod and causing the first rotating plate and the limit plate to separate, resulting in the gasket being able to fall directly from the second through-hole between the first rotating plate and the limit plate, making it difficult for the gasket to move with the first rotating plate, avoiding the gasket from being stuck.

[0020] Optionally, a accommodating bar is slidably connected to the mounting cover, and a accommodating groove for inserting the accommodating bar is provided on the fixing bar; when the accommodating bar is inserted into the accommodating groove, the accommodating bar does not protrude from the mounting cover, and at this time the mounting cover is fixed on the mounting rod.

[0021] By adopting the above technical solution, the mounting cover can be fixed on the mounting rod by inserting the accommodating bar into the accommodating groove, so that the mounting cover can limit the fixing bar; at the same time, the accommodating bar does not protrude from the mounting cover, and the staff can directly observe whether the accommodating bar protrudes from the mounting cover to know whether the mounting cover is installed in place.
