Description

Technical Field

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

[0002] A flange nut is a nut with a wide flange on one end that acts as an integrated washer. Flange nuts consist of a nut portion as well as a flange portion. This serves to distribute the pressure of the nut across the component being secured, thereby reducing the possibility of component damage and making it less likely to loosen due to an uneven fastening surface. These nuts are mostly hexagonal in shape and made of hardened steel, often with a zinc coating. In many cases, the flange is fixed and rotates with the nut. The flange may be serrated to provide a locking action, with the serrations 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 from the nut from moving the fastener, thereby maintaining the nut's holding force.

[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

[0004] The technical problem to be solved by the present invention is to provide a flange nut assembly machine in response to the above-mentioned existing technical status. The flange nut assembly machine of the present invention is composed of a slide plate assembly consisting of front, middle and rear slide plates. The upper surface of the middle slide plate is higher, and the nut part slides along it. The flange positioning slide grooves on both sides accommodate the flange parts to ensure that the nut posture is stable and achieve preliminary regular sorting. 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.

[0029] The present invention is described in further detail below with reference to the accompanying drawings:

[0030] like Figures 1 to 6 As shown,

[0031] A flange nut assembly machine, comprising:

[0032] The 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 via 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 adopt friction transmission;

[0033] 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 stop convex body is provided on the front end of the skateboard. The nut can slide along the skateboard, and the nut that abuts against the nut stop convex body 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 production. 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. When the handheld screw is directly aligned with the screw hole of the nut In order to prevent the nut from falling out of the assembly port during the process of sliding downward along the slide 2, there is a certain height between the bottom edge of the assembly port and the slide of the slide 2. 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 slide groove depth 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. 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. The slide plate assembly 3 includes a front slide plate 31, a middle slide plate 32 and a rear slide plate 33. The front slide plate 31, the middle slide plate 32 and the rear slide plate 33 each slide plate The number of plates can be composed of one or more thin plates. The front slide plate 31 and the rear slide plate 33 are respectively fixed on both sides of the middle slide plate 32. The upper surface of the middle slide plate 32 is higher than the upper surface of the front slide plate 31 and the upper surface of the rear slide plate 33. The nut portion of the flange nut slides along the upper surface of the middle slide plate 32. A flange positioning groove 25 adapted to the flange portion of the flange nut is formed between the middle slide plate 32 and the front side plate 22 and the rear side plate 23. The flange portion 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 block 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 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 slides on both sides accommodate the flange parts to ensure that the nut posture is stable 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 stop 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 on one side close to the nut sliding hole slides out of the slide from the sliding hole, while the nut in the slide 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.

[0034] 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 assembly. Hand-held or mechanically clamped screws and nuts are not within the scope of this invention. This invention solves the problem of nut rotation. The present invention preferably uses a hand-held screw and a nut. 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, and the end can slightly enter the screw hole of the nut. When the nut is provoked, the rear end surface of the nut slides along the rear side plate of the slideway 2 to prevent the nut from separating from the end of the screw, so that the nut contacts the outer peripheral surface of the driving wheel 12. 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. The nut separates from the slideway 2 from the upper opening of the slideway 2 or the assembly port 21. During the rotation of the nut, the friction between the driving wheel 12 and the nut naturally drives the nut to rotate. The nut is disengaged from the upper opening of the slide 2 at a certain angle, and the rear side plate of the slide 2 does not hinder the screw from moving backward. If the nut is not disengaged from the upper opening of the slide 2 in time during the assembly process, the rear side plate hinders the screw from moving backward. The nut can continue to rotate under the action of the driving wheel 12 and move along the axial direction of the driving wheel 12, which can also make the nut screwed on the screw. Therefore, the assembly operation is extremely convenient and simple. When the screw connection length is long, the screw can be wound around the driving wheel 12 at a certain angle so that the rear side plate does not hinder the screw, and the nut can continue to be screwed. It contacts the driving wheel 12, so that the nut and the screw are screwed to a predetermined position. The nut assembly machine is small in size, extremely low in cost, and easy to carry. It uses the friction of the outer ring of the driving wheel 12. Since the outer diameter of the driving wheel 12 is much larger than the outer diameter of the nut, it drives the nut 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, 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. At the same time, the screw is not restricted by the nut assembly machine, thereby improving the assembly speed and efficiency.

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 slide 2. One end of the spring 45 is against the anti-drop cap 44, and a flat washer is provided on the anti-drop cap 44 to increase the contact area with one end of the spring 45. The other end of the spring 45 is against the bottom surface of the guide plate.

The end of the connecting line of the foot switch is connected to a plug and connected to the female 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 chamber 41 is vibrated into the slideway, but also reduce the noise impact of the vibration of the vibration motor 46.

[0036] In the embodiment, a baffle assembly 5 is provided 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 the same 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 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 32 are The spacing setting is very critical. The spacing 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 then 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.

[0037] In the embodiment, a blocking body 55 is provided on the front baffle 51 or the rear baffle 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 of 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.

[0038] In the embodiment, 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.

[0039] In the embodiment, the adjustment hole 28 is a vertical bar hole. The fastener inserted into 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 32. In actual operation, by operating the fastener to move it up and down within the vertical bar hole, the spacing between the middle baffle 52 and the middle slide 32 can be flexibly adjusted. For example, when processing flange nuts of different specifications and sizes, if the nut portion is slightly larger, the fastener can be moved upward to appropriately increase the spacing between the middle baffle 52 and the middle slide 32 to ensure smooth passage of the nut portion. If the outer diameter of the flange portion of the flange nut is smaller, in order to better restrict its position, the fastener can be moved downward to reduce the spacing between the two, allowing the flange portion to be more firmly positioned. This allows the baffle assembly 5 to better adapt to flange nuts of various specifications, thereby effectively improving the efficiency of flange nut sorting.

[0040] In the embodiment, 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. Such rounded bottoms can effectively reduce the friction generated when the flange nut contacts the bottom of the baffle during transportation. When the flange nut slides along the slide and passes through the bottom of the baffle, its movement is smoother due to the absence of sharp edges and 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, which can guide the flange nut 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 enable the nut to slide smoothly into the correct position, just like the role of a funnel, thereby improving the conveying efficiency.

[0041] In the embodiment, 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 being hindered, and the nut is in contact with the rear side plate to facilitate nut assembly.

[0042] In this embodiment, the two ends of the baffle assembly 5 are located on either side of the nut drop hole 26. When approaching the area where the nut drop hole 26 is located, the baffle assemblies 5 on either side can effectively block and guide the nut. This prevents flange nuts from accidentally deviating from the normal conveying track when approaching the drop hole. It ensures that only flange nuts that meet specific conditions (such as those located within a specific flange positioning groove and can slide out of the nut drop hole) can exit the slide through the drop hole. The remaining nuts continue to be guided forward in the correct direction by the baffle assembly 5. This ensures the accuracy of the nut drop screening process and ensures that the nuts are restrained only when passing through the drop hole 26. This reduces manufacturing difficulty and manufacturing precision and avoids the phenomenon of jamming caused by long-term nut restraint.

[0043] In the embodiment, a shielding body 6 is provided on the upper opening of the nut conveying groove 24 , and the shielding body 6 does not block 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 .

[0044] The use of this utility model:

[0045] The driving wheel and the nut of the utility model are driven by friction. 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 placing bin, which is low in cost and can ensure that the nut enters the slideway and ensures the supply of the nut. The method of using the utility model is to plug the plug of the power adapter into the power supply, turn on the main switch, the main motor rotates, drive the driving wheel to rotate, put the nut into the nut placing bin, step on the foot switch with your foot, the vibration motor vibrates, the nut in the nut placing bin vibrates, and the nut in the nut placing bin falls into the slideway through the nut falling hole, and the nut slides along the slideway to the driving wheel. The upper surface of the middle slide plate is higher, and the nut part slides along it. The flange positioning slide grooves on both sides accommodate the flange part, 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 here, the convex block blocks The stop 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, while the nut in the slide groove on the other side continues to move toward the assembly end, completing the screening sorting. The flange nut is against the nut stop convex body of the slide plate and stops sliding. After an appropriate amount of nuts enter the slide, release the foot switch, the vibration motor stops vibrating, the screw hole of the nut is facing the stirring port, hold the screw rod, insert the end of the screw rod into the screw hole of the nut from the stirring port to stir the nut. When stirring, make the rear end face of the nut move along the rear end of the slide The side plate slides to prevent the nut from separating from the end of the screw, so that the nut contacts the outer circumference of the driving wheel. The outer circumference of the driving wheel and the outer circumference of the nut or the end edge of the nut are friction-driven, and the driving nut rotates and is threaded into the screw. The nut is rotated to the predetermined position as required, and the screw is lifted to separate the nut from the driving wheel. The next screw is assembled. The vibration motor is controlled to vibrate intermittently with the foot switch to add nuts to the slide to ensure the supply of nuts in the slide. After assembling the required number of screws, the main switch is turned off to complete the assembly.
