Description

Technical Field

[0001] The invention relates to the technical field of screw and nut assembly, and in particular to a flange nut assembly machine. Background Art

[0002] A flange nut is a nut that has a wide flange on one end that acts as an integral washer. Flange nuts consist of a nut portion as well as a flange portion. This serves to distribute the pressure of the nut over the component being secured, thereby reducing the possibility of component damage and making it less likely to loosen due to the uneven fastening surface. Most of these nuts are hexagonal in shape and are made of hardened steel, often with a zinc coating on the surface. In many cases, the flange is fixed and rotates with the nut. The flange may be serrated to provide a locking action. The serrations are angled so that the nut will not rotate in a direction that would loosen the nut. Due to the serrations, they cannot be used with washers or on scratched surfaces. The serrations help prevent vibration of the nut from moving the fastener, thereby maintaining the retention of the nut.

[0003] In the prior art, patent ZL202323049873.5 discloses a nut machine, which is mainly used for assembling hexagonal nuts. However, due to the special structure of flange nuts, it is impossible to distinguish the front and back sides of flange nuts, resulting in a chaotic arrangement of nuts in the slideway and inability to achieve effective assembly. Therefore, improvements are made to address this problem. Summary of the invention

According to customer needs, nut sliding holes are opened on the front side plate or the rear side plate. The nut sliding holes and convex stops on the front side plate or the rear side plate play a screening role. When the nut slides to this point, the convex stop prevents the nut from continuing to slide, so that the flange nut in the slide groove on one side close to the nut sliding hole slides out of the slide from the sliding hole, while the nut in the slide groove on the other side continues to move forward to the assembly end, completing the screening sorting. The structure is simple and the cost is low.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings: Embodiment 1

[0021] like Figures 1 to 6 As shown, A flange nut assembly machine, comprising: A bracket 1 is provided with a power device 11, and a driving wheel 12 is provided on the output shaft of the power device 11. The power device is connected to a power source through a wire to drive the driving wheel to rotate. The driving wheel can be made of rubber, silicone, polyurethane and other materials, and has the characteristics of elasticity and wear resistance. The driving wheel and the nut are driven by friction. The slide 2 is mounted on the bracket 1, and an assembly port 21 is provided on the front end of the slide 2. A nut stopping protrusion is provided on the front end of the skateboard. The nut can slide along the skateboard, and the nut abutting against the nut stopping protrusion of the skateboard stops sliding and does not contact the driving wheel. The screw hole of the nut is opposite to the provoking port, which can improve the accuracy of the slide and reduce the difficulty of manufacturing. The nut screw hole at the assembly port 21 in the slide 2 is opposite to the assembly port 21. The slide 2 is tilted and mounted on the bracket so that the nut can slide along the slide 2. An assembly port is provided on the front side of the slide 2. The nut screw hole at the assembly port in the slide 2 is opposite to the assembly port, which is convenient for the subsequent assembly process. The screw hole of the nut can be directly aligned with the screw hole of the nut when the screw is held. In order to prevent the nut from falling out of the assembly port during the downward sliding process along the slide 2, there is a certain height between the bottom edge of the assembly port and the slide plate of the slide 2, and the height should be less than or equal to the minimum radial thickness from the screw hole to the outer periphery of the nut, which can prevent the nut from falling out and expose the screw hole. The depth of the slide groove of the slide 2 is greater than or equal to the diagonal length of the nut, and the nut cannot be exposed from the slide 2; the slide 2 includes a front side plate 22, a rear side plate 23 and a slide plate assembly 3, and the two sides of the slide plate assembly 3 are respectively connected to the front side plate 22 and the rear side plate 23 to form a nut conveying groove 24, and the slide plate assembly 3 includes a front slide plate 31, a middle slide plate 32 and a rear slide plate 33, and each slide plate of the front slide plate 31, the middle slide plate 32 and the rear slide plate 33 The number of plates can be composed of one or more thin plates. The front plate 31 and the rear plate 33 are respectively fixed on both sides of the middle plate 32. The upper surface of the middle plate 32 is higher than the upper surface of the front plate 31 and the upper surface of the rear plate 33. The nut part of the flange nut slides along the upper surface of the middle plate 32. A flange positioning groove 25 adapted to the flange part of the flange nut is formed between the middle plate 32 and the front side plate 22 and the rear side plate 23. The flange part of the flange nut slides along the flange positioning groove 25. A nut sliding hole 26 is opened on the front side plate 22 or the rear side plate 23. A convex stopper 34 is provided in the flange positioning groove 25 on the side of the nut sliding hole 26. The flange in the flange positioning groove 25 The nut slides out of the slide 2 from the nut sliding hole 26, and the nut located in the other flange positioning slide groove 25 can slide to the assembly end of the slide 2. The upper surface of the middle slide is higher, and the nut part slides along it. The flange positioning slide grooves on both sides accommodate the flange parts to ensure the stability of the nut posture and achieve preliminary regular sorting. According to customer needs, a nut sliding hole is opened on the front side plate or the rear side plate. The nut sliding hole and the convex stopper on the front side plate or the rear side plate play a screening role. When the nut slides to this point, the convex stopper prevents the nut from continuing to slide, so that the flange nut in the slide groove on one side of the nut sliding hole slides out of the slide from the sliding hole, while the nut in the slide groove on the other side continues to move toward the assembly end, completing the screening sorting. The structure is simple and the cost is low.

[0022] The present invention collectively refers to bolts, studs, through-thread screws, etc. that need to be assembled with nuts as screws. Therefore, the screw described in the present invention is a cylindrical body with external threads and a nut assembled together. Hand-held or mechanically clamped screws and nuts are not within the scope of the present invention. The present invention solves the problem of nut rotation. The present invention preferably uses a hand-held screw and a nut to cooperate. The end of the screw is pressed into the screw hole of the nut at the assembly port 21. The end of the screw is generally chamfered and smooth. The end can slightly enter the screw hole of the nut, so that the screw can be rotated when it is stirred. The rear end surface of the female slides along the rear side plate of the slideway 2 to prevent the nut from being separated from the end of the screw rod, so that the nut contacts the outer peripheral surface of the driving wheel 12, and the nut is provoked to contact the outer peripheral surface of the driving wheel 12. The outer peripheral surface of the driving wheel 12 and the outer peripheral surface of the nut or the end surface edge of the nut are frictionally transmitted to drive the nut to rotate and be threadedly connected with the screw rod. The nut is separated from the slideway 2 from the upper opening of the slideway 2 or the assembly port 21. During the rotation of the nut, due to the friction between the driving wheel 12 and the nut, the nut is naturally driven to rotate a certain angle. The nut is separated from the slideway 2 from the upper opening of the slideway 2, and the rear side plate of the slideway 2 will not hinder the screw from moving backward. If the nut is not separated from the slideway 2 from the upper opening in time during the assembly process, the rear side plate will hinder the screw from moving backward. Under the action of the driving wheel 12, the nut can continue to rotate and move along the axial direction of the driving wheel 12, and the nut can also be screwed on the screw. Therefore, the assembly operation is extremely convenient and simple. When the screw connection length is long, the screw is wound around the driving wheel 12 at a certain angle so that the rear side plate will not hinder the screw, and the nut can continue to be screwed with the driving wheel 12. The wheel 12 contacts, so that the nut and the screw are screwed to the predetermined position. The nut assembly machine is small in size, extremely low in cost, and easy to carry. The outer ring friction of the driving wheel 12 is used. Since the outer diameter of the driving wheel 12 is much larger than the outer diameter of the nut, the nut is driven to rotate as a speed-up transmission. The nut rotates faster, which makes the assembly speed faster. Since there is no obstacle behind the slide slot, it will not block the movement of the screw, so the nut can be screwed to any position of the screw. The driving wheel 12 can be quickly separated from the nut and the screw is not restricted by the nut assembly machine, thereby improving the assembly speed and efficiency.

At the same time, it is easier for beginners to operate, and no skills are required. Only by putting the nuts into the nut supply part, the nuts can be automatically supplied into the slide; guide plates are respectively provided on both sides of the rear end of the slide 2, and the guide plates and the side plates of the slide 2 are bent, and the angle between the guide plates and one side plate of the slide 2 is 90° to 145°. °, the angle of the embodiment given by the present invention is 90°, the nut supply part 4 includes a nut placing bin 41, and the nut placing bin 41 is movably arranged on the guide plate; a nut dropping hole 42 is provided at the bottom of the nut placing bin 41, and the nut dropping hole 42 corresponds to the upper opening of the slide 2, and the nuts in the nut placing bin 41 fall into the slide 2 through the nut dropping hole 42, and the bottom plate of the nut placing bin 41 can provide more vibration force for the nuts in the nut placing bin 41, thereby increasing the probability of the nuts entering the slide 2; an anti-slip component is provided between the nut placing bin 41 and the guide plate to prevent the nut placing bin 41 from detaching from the guide plate; a driving part is provided on the nut placing bin 41, and the driving part drives the nut placing The nut placing bin 41 is provided with a vibration motor 46, and a fixing frame is provided on the outer wall of the nut placing bin 41.

The fixing frame is fixed to the outer side of the rear end of the nut placing bin 41 by rivets, away from the driving wheel 12, and will not affect the operation; the anti-slipping component includes a guide rod 43 and an anti-slipping cap 44. The guide rod 43 is respectively arranged on both sides of the nut falling hole 42. The guide rod 43 can be a screw. One end of the guide rod 43 is fixed to the bottom of the nut placing bin 41. The head of the guide rod 43 is in the nut placing bin 41. A flat washer is provided between the head of the guide rod 43 and the upper surface of the bottom of the nut placing bin 41 to increase the contact area and reduce the vibration to the nut To prevent damage to the connection of the placement bin 41 and to improve the service life of the nut placement bin 41, a through hole is provided on the guide plate of the slideway 2 at a position corresponding to the guide rod 43. The through hole is larger than the outer diameter of the guide rod 43 and smaller than the inner diameter of the spring 45 described later. The other end of the guide rod 43 passes through the through hole and is connected to the anti-drop cap 44; a spring 45 is sleeved on the guide rod 43, and the spring 45 is located between the anti-drop cap 44 and the bottom surface of the guide plate of the slideway 2. One end of the spring 45 abuts against the anti-drop cap 44. The anti-drop cap 44 is provided with a flat gasket to increase the contact area with one end of the spring 45. The other end of the spring 45 abuts against the bottom surface of the guide plate. The spring 45 ensures that the nut placement bin 41 fits on the guide plate without affecting vibration.A spacer is sleeved on the guide rod 43, and the spacer is located in the spring 45. One end of the spacer abuts against the anti-drop cap 44, and the other end of the spacer abuts against the bottom lower surface of the nut placement bin 41.

The end of the connecting line of the foot switch is connected to a plug and connected to the plug socket on the circuit. The foot switch can control the intermittent vibration of the vibration motor 46, which can not only ensure that the nut placement bin 41 is vibrated into the slideway, but also reduce the noise impact of the vibration of the vibration motor 46. ;

[0024] A baffle assembly 5 is arranged in the nut conveying groove 24, and the baffle assembly 5 is provided with a front baffle 51, a middle baffle 52 and a rear baffle 53. The front baffle 51 and the rear baffle 53 can be replaced with gaskets of equal thickness to reduce material costs. The lower surface of the middle baffle 52 is lower than the lower surface of the front baffle 51 and the lower surface of the rear baffle 53. A flange retaining groove 54 adapted to the flange portion of the flange nut is formed between the middle baffle 52 and the front side plate 22 and the rear side plate 23. The spacing between the middle baffle 52 and the middle slide plate 32 is greater than the diagonal length of the nut portion of the flange nut and less than the outer diameter of the flange portion of the flange nut. The middle baffle 52 and the middle slide plate 32 are The spacing setting is very critical and is carefully designed. It is larger than the diagonal length of the nut part of the flange nut, so that the nut part can pass smoothly and will not be stuck; and smaller than the outer diameter of the flange part of the flange nut, so that the flange part will be restricted to the corresponding area, and the flange nut can move in an orderly manner according to the established structure and space restrictions during the conveying process, further standardizing the conveying state of the flange nut in the nut conveying trough, and ensuring the accuracy and stability of the conveying.

[0025] A blocking body 55 is provided on the front baffle plate 51 or the rear baffle plate 53 located on the side of the nut sliding hole 26. The blocking body 55 corresponds to the convex block 34 on the slide plate, which can effectively prevent the flange nut from sliding and smoothly slide out from the nut sliding hole 26. The nut sliding hole 26 is close to the support plate, and the vibration force of the vibration motor is transmitted to the slide, which is conducive to the nut passing through the gap between the baffle assembly 5 and the slide plate.

[0026] Adjustment holes 28 corresponding to the baffle assembly 5 are provided on the front side plate 22 and the rear side plate 23 , and the baffle assembly 5 is fixed between the front side plate 22 and the rear side plate 23 by fasteners for easy connection.

[0027] The adjustment hole 28 is a vertical bar hole. The fasteners inserted in the baffle assembly 5 can move up and down along the adjustment hole 28 to adjust the spacing between the middle baffle 52 and the middle slide plate 32. In actual operation, by operating the fasteners to move them up and down in the vertical bar holes, the spacing between the middle baffle 52 and the middle slide plate 32 can be flexibly adjusted. For example, when it is necessary to process flange nuts of different specifications and sizes, if the nut portion is slightly larger, the fasteners can be moved upward to appropriately increase the spacing between the middle baffle 52 and the middle slide plate 32 to ensure that the nut portion can pass smoothly; and when the outer diameter of the flange portion of the flange nut is small, in order to better limit its position, the fasteners can be moved downward to reduce the spacing between the two, so that the flange portion is more firmly in the corresponding position, so that the baffle assembly 5 can better adapt to flange nuts of various specifications, thereby effectively improving the sorting efficiency of flange nuts.

[0028] The bottoms of the front baffle 51, the middle baffle 52 and the rear baffle 53 of the baffle assembly 5 are rounded and smooth, and this rounded bottom can effectively reduce the friction generated when the flange nut contacts the bottom of the baffle during the conveying process. When the flange nut slides along the slide and passes through the bottom of the baffle, it moves more smoothly due to the absence of sharp corners, avoiding the speed reduction or even jamming caused by excessive friction, which helps to maintain a stable conveying speed of the flange nut, thereby improving the sorting efficiency. A certain angle of inclined surface is designed at the entrance and exit of the baffle, so that the flange nut can be guided to enter and leave the restricted area of ​​the baffle assembly 5 more smoothly, reducing collisions and jams. When the flange nut enters, the inclined surface can make the nut slide smoothly into the correct position, just like the role of a funnel, improving the conveying efficiency.

[0029] The middle slide 32 and the rear slide 33 are located at the assembly end of the slide 2, and their upper surfaces are flush with the front slide 31, which can provide a continuous and flat sliding plane for the flange nut, so that when the nut is assembled with the screw, it can be pushed backward by the screw without obstruction, and the nut is in contact with the rear side plate to facilitate nut assembly.

[0030] The two ends of the baffle assembly 5 are located on both sides of the nut sliding hole 26. When approaching the area where the nut sliding hole 26 is located, the baffle assembly 5 located on both sides can play an effective blocking and guiding role. It can prevent the flange nut from accidentally leaving the normal conveying track when it is about to reach the sliding hole, ensuring that only the flange nut that meets specific conditions (such as the part of the nut that is located in the specific flange positioning slide groove and can slide out of the nut sliding hole) can leave the slideway through the sliding hole, and the rest will continue to be guided by the baffle assembly 5 to be conveyed forward in the correct direction, ensuring the accuracy of the nut sliding screening process, and ensuring that the nut is constrained only when passing through the sliding hole 26 section, reducing the manufacturing difficulty and manufacturing accuracy, and avoiding the phenomenon of material jamming caused by the nut being constrained for a long time.

[0031] A shielding body 6 is provided on the upper opening of the nut conveying groove 24 . The shielding body 6 does not shield the assembly opening. The shielding body 6 prevents the nut from escaping from the slideway through the upper opening of the nut conveying groove 24 .

[0032] Method of use of the present invention: The driving wheel and the nut of the present invention are driven by friction, and the outer diameter of the driving wheel is much larger than the outer diameter of the nut. Therefore, when the driving wheel rotates one circle, the nut can rotate several circles, thereby greatly improving the assembly speed. The vibration motor is used to vibrate the nut placement bin, which is low in cost and can ensure that the nut enters the slideway to ensure the supply of nuts. The use method of the present invention is as follows: insert the plug of the power adapter into the power supply, turn on the main switch, the main motor rotates, drives the driving wheel to rotate, puts the nut into the nut placement bin, steps on the foot switch with the foot, the vibration motor vibrates, the nuts in the nut placement bin vibrate, the nuts in the nut placement bin fall into the slideway through the nut falling hole, and the nuts slide along the slideway to the driving wheel. The upper surface of the middle slide board is higher, and the nut part slides along it. The flange positioning slide grooves on both sides accommodate the flange part to ensure that the nut posture is stable and realize preliminary regular sorting. According to customer needs, a nut sliding hole is opened on the front side plate or the rear side plate. The nut sliding hole and the convex block on the front side plate or the rear side plate play a screening role. When the nut slides to this point, the convex block prevents the nut from sliding to this point. The nut continues to slide, so that the flange nut in the slide groove on one side of the nut sliding hole slides out of the slide from the sliding hole, and the nut in the slide groove on the other side continues to move forward to the assembly end, completing the screening sorting, the flange nut and the nut stop convex body of the slide plate are against each other, stop sliding, release the foot switch after an appropriate amount of nuts enter the slide, the vibration motor stops vibrating, the screw hole of the nut is opposite to the stirring mouth, hold the screw rod, insert the end of the screw rod into the screw hole of the nut from the stirring mouth to stir the nut, and when stirring, make the rear end face of the nut slide along the rear side plate of the slide to prevent the nut from separating from the end of the screw rod, make the nut contact with the outer peripheral surface of the driving wheel, the outer peripheral surface of the driving wheel and the outer peripheral surface of the nut or the end face edge of the nut friction transmission, drive the nut to rotate and be threaded with the screw rod, rotate the nut to the predetermined position as required, lift the screw rod, separate the nut from the driving wheel, continue to assemble the next screw, intermittently use the foot switch to control the vibration of the vibration motor, replenish nuts in the slide, ensure the supply of nuts in the slide, assemble the required number of screws, turn off the main switch, and complete the assembly.

The slide is tilted and mounted on the bracket, and the stop part includes a U-shaped nut stop part 8, and the U-shaped nut stop part 8 includes an upper baffle 81. The upper baffle 81 forms an arc structure with the bottom plate, and the upper baffle 81 can block the nut at the slide assembly port 21 from detaching from the slide from the upper opening. The length of the upper baffle 81 is approximately the diagonal length of each nut, which can not only ensure that the nut at the assembly port 21 is directly opposite to the assembly port 21, but also ensure that the nuts arranged behind are not constrained by the upper baffle 81 to avoid the nut being stuck. The end of the upper baffle 81 is rounded and excessively smooth, and the nut can slide along the bottom plate, and the nut that is against the U-shaped nut stop part 8 of the bottom plate has a screw hole directly opposite to the assembly port 21.

[0034] The driving friction member 7 also includes an outer sleeve 72, and the driving wheel 12 is arranged in the outer sleeve 72. The outer sleeve 72 includes a connecting section and a main section, and the connecting section is fixedly connected to the main section. Under the drive of the connecting section, the main section can rotate. The connecting section of the outer sleeve 72 is supported on the bearing seat 9 through a bearing, and the bearing seat 9 is fixed on the bracket. The connecting section of the outer sleeve 72 is matched with the power device for transmission. The transmission member includes a driving wheel 91, a driven wheel 92 and a transmission belt 93. The driving wheel 91 is connected to the output shaft of the power device, and the driven wheel 92 is sleeved and fixed on the connecting section of the outer sleeve 72. The transmission belt 93 is sleeved on the driving wheel 91 and the driven wheel 92. The driving wheel 91 drives the driven wheel 9 through the transmission belt 93 2 rotates, thereby realizing the rotation of the outer sleeve 72. Screw holes are provided on the driving wheel 91 and the driven wheel 92, which are locked by corresponding locking screws. The interior of the connecting section of the outer sleeve 72 is connected with the interior of the main section to form a step hole, which can prevent the driving friction pad from moving toward the connecting section. The advantage of this embodiment is that the threaded connection length of the nut and the screw rod will not be limited by the length of the driving friction member 7, thereby realizing the threaded connection between the nut and the screw rod over a long distance. A fixing seat is provided on the bracket, and a fixing hole is provided on the fixing seat. The fixing hole is directly opposite to the center of the outer sleeve 72. The regulating rod is inserted in the fixing hole and can move up and down along the axial direction of the fixing hole to adjust the length of the nut screwed on the screw rod, and is locked by the locking screw on the fixing seat.
