Description

Technical Field

[0001] This application relates to the field of riveting technology, and particularly to nut riveting equipment. Background Art

[0002] A nut is a part that can tightly connect mechanical equipment. It is usually used in conjunction with a bolt to achieve the purpose of fastening components, that is, by passing the bolt through a hole provided in the component and connecting a nut to the other end of the bolt to fasten the component. Nuts used in automobiles usually include a nut body and an annular cap integrated with the nut. Some special nuts need to be riveted with a gasket to increase the overall wear resistance.

[0003] The traditional gasket processing method is to manually place it and then send it to a riveting press for riveting. Not only is the riveting efficiency low, but also safety accidents are likely to occur. Summary of the Invention

[0004] In order to improve the riveting efficiency of nuts and gaskets, this application provides nut riveting equipment.

[0005] The nut riveting equipment provided by this application adopts the following technical solutions: The nut riveting equipment includes a frame and a first feeding mechanism, a second feeding mechanism, a stamping device, and a rotating disk arranged on the frame for conveying nuts, conveying gaskets, and stamping. A rotating groove for the rotating disk to rotate is provided on the frame. A plurality of material placing grooves are evenly arranged on the circumference of the rotating disk. The first feeding mechanism is used to convey nuts into the material placing grooves, and the second feeding mechanism is used to convey gaskets to align with the material placing grooves containing nuts. A stepping motor for driving the rotating disk to rotate is arranged on the frame. The stamping device is used to rivet the gasket into the nut. An outlet hole is provided on the frame, and a collection bucket for receiving the finished product is placed at the outlet hole.

[0006] By adopting the above technical solutions, when the equipment is started, the rotating disk rotates under the action of the stepping motor. At the same time, the material nuts are conveyed to the material placing grooves of the rotating disk through the first feeding mechanism. The material placing grooves receiving the nuts continue to rotate to align with the lowest-end gaskets in the second feeding mechanism. Subsequently, under the action of the stamping device, the gasket is riveted into the nut. The rotating disk continues to rotate to the outlet hole under the action of the stepping motor, so that the riveted nuts fall from the material placing grooves into the outlet hole and then fall into the collection bucket through the outlet hole to complete the discharging. Thus, the automatic feeding of nuts and gaskets, the riveting of gaskets and nuts, and the discharging of products are completed, with higher efficiency.

[0007] Preferably, the first feeding mechanism includes a first vibrating disk and a first track. Nuts are stored in the first vibrating disk. The first track is communicated with the first vibrating disk, and one end of the first track away from the first vibrating disk is communicated with the feeding slot. The second feeding mechanism includes a second vibrating disk and a second track. Washers are stored in the second vibrating disk. One end of the second track is communicated with the second vibrating disk. The first track and the second track are horizontally and juxtaposedly connected. One end of the second track away from the second vibrating disk is aligned with the feeding slot containing nuts.

[0008] By adopting the above technical solution, the rotating disk rotates at the same frequency under the action of the stepping motor. Nuts are arranged one by one under the action of the first vibrating disk and enter the first track, and then fall into the feeding slot. Washers are arranged one by one under the action of the second vibrating disk and enter the second track. After the feeding slot with nuts on the rotating disk rotates again, it is aligned with the washer at the lowest end in the second track. At this time, under the action of the impact device, the washer is riveted into the nut.

[0009] Preferably, the stamping device includes a push rod, a riveting rod, a push block and a hydraulic cylinder for driving the push block to move. The push rod and the riveting rod are both fixedly connected to the push block. A push hole is formed in the second track, and the push hole is aligned with the feeding slot containing nuts. The reciprocating push rod passes through the push hole and pushes the washer into the nut. The riveting rod is aligned with the feeding slot where the nut with the washer is located, and the riveting rod abuts against the end face of the nut.

[0010] By adopting the above technical solution, the frequency of the hydraulic cylinder driving the push block to move is consistent with the frequency of the stepping motor driving the rotating disk to rotate. Therefore, when the rotating disk rotates, the push block drives the push rod and the riveting rod to move away from the connecting block under the drive of the hydraulic cylinder. When the feeding slot containing nuts on the rotating disk rotates to be aligned with the push hole, the push block drives the push rod to pass through and slide on the inner wall of the push hole under the drive of the hydraulic cylinder and pushes the washer at the lowest end in the first track into the nut. At the same time, the riveting rod moves towards the feeding slot below the push rod until it abuts against and rivets the end face of the nut, and rivets the metal washer reserved on the nut end face inward to fix the washer.

[0011] Preferably, the stamping device further includes a correcting rod. The correcting rod is fixedly connected to the push block and is located between the push rod and the riveting rod. The correcting rod can be inserted into the nut and abut against the washer.

[0012] By adopting the above technical solution, after the push rod pushes the washer into the nut, the nut in the feeding slot rotates to be aligned with the correcting rod. The correcting rod is just inserted into the nut and abuts against the washer under the push of the push block, which can correct the positions of the nut and the washer, avoid the position deviation of the washer in the nut, and reduce the probability of defective products.

[0013] Preferably, a material taking member is fixedly installed on the frame. The material taking member slides relative to the surface of the rotating disk. The material taking member abuts against the peripheral side wall of the nut. An outlet is formed in the inner wall of the rotating groove, and the outlet is located above the outlet hole.

[0014] By adopting the above technical solution, when the feeding groove containing the completed riveted nut rotates to abut against the material taking member, the nut is separated from the feeding groove under the push of the material taking member, so as to remove the completed product from the rotating disk, improve the discharging effect, and reduce the possibility that the nut is stuck in the feeding groove and does not fall off.

[0015] Preferably, a bracket is fixedly connected to the outer side wall of the second track. A fuel pipe is fixedly installed on the bracket. The fuel pipe is located directly above the push rod. The fuel pipe contains lubricating oil. A piston rod is slidably connected in the fuel pipe. The frame is provided with a driving assembly for driving the piston rod to move, and the fuel pipe is provided with a reset assembly for driving the piston rod to reset.

[0016] By adopting the above technical solution, in the stamping device, when the push rod reciprocally penetrates through the push hole, the outer side wall of the push rod continuously rubs against the inner wall of the push hole, damaging the surface of the push rod and increasing the temperature. In order to reduce wear, when the impact device is working, the piston rod in the fuel pipe pushes the lubricating oil in the fuel pipe to drip onto the push rod drop by drop under the action of the driving assembly and the reset assembly, so that the lubricating oil flows on the push rod to wrap its side wall, thereby reducing friction.

[0017] Preferably, the driving assembly includes a driving wheel, a driven wheel, a chain, a first rotating rod, a second rotating rod, a bevel gear set, a worm, a worm wheel and a cam. The first rotating rod penetrates through and rotates on the frame. The second rotating rod rotates on the outer side wall of the second track. A fixing frame is fixedly connected to the second track. The worm penetrates through and rotates on the fixing frame. The driving wheel is fixedly sleeved on the rotating shaft of the stepping motor. The driven wheel is fixedly sleeved on the first rotating rod. The driving wheel drives the driven wheel through the chain. The worm and the first rotating rod are connected by the bevel gear set. The cam is fixedly sleeved on the second rotating rod. The worm wheel is fixedly sleeved on the second rotating rod and meshes with the worm. One end of the piston rod away from the fuel pipe is fixedly connected with an arc plate, and the cam rotates and abuts against the inner wall of the arc plate.

[0018] By adopting the above technical solution, when the stepping motor drives the rotating disk to rotate, it also drives the driving wheel to rotate. The driving wheel rotates to drive the driven wheel to rotate through the chain. The driven wheel rotates to drive the first rotating rod to rotate. The first rotating rod rotates to drive the worm to rotate through the bevel gear set. The worm rotates to drive the second rotating rod to rotate through the worm wheel. The second rotating rod rotates to drive the cam to rotate. The cam rotates to push the arc plate downward to push the piston rod to move, so as to push the lubricating oil out of the fuel pipe and drip onto the push rod.

[0019] Preferably, the reset assembly includes a reset block and a reset spring. The reset block is fixedly connected to the piston rod, and both ends of the reset spring are fixedly connected to the oil pipe and the reset plate respectively.

[0020] By adopting the above technical solution, when the convex end of the cam rotates away from the arc plate, the reset plate pushes the arc plate to move upward under the push of the reset spring, thereby driving the piston rod to move upward to facilitate the next push.

[0021] Preferably, a telescopic groove is formed at one end of the worm away from the worm gear. A sliding rod slides in the telescopic groove. The sliding rod and the first rotating rod are connected through the bevel gear set. The sliding rod is provided with a first jack and a second jack. The worm is provided with a connection hole, and the connection hole is aligned with the first jack or the second jack. A fixing pin is inserted into the first connection hole.

[0022] By adopting the above technical solution, when the sliding rod is connected to the first rotating rod, the first jack and the connection hole are aligned and fixed by the fixing pin. After the lubricating oil is added to the push rod, the staff removes the fixing pin and pushes the sliding rod to move into the telescopic groove until the second jack is aligned with the connection hole and the fixing pin is inserted and fixed. At this time, the connection between the first rotating rod and the worm is disconnected, and the lubricating oil stops being added.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. After the equipment is started, the rotating disk rotates under the action of the stepping motor. At the same time, the material nut is conveyed to the discharging groove of the rotating disk through the first feeding mechanism. The discharging groove receiving the nut continues to rotate until it is aligned with the lowest gasket in the second feeding mechanism. Subsequently, under the action of the stamping device, the gasket is riveted into the nut. The rotating disk continues to rotate under the action of the stepping motor to the discharging hole, so that the riveted nut falls from the discharging groove into the discharging hole and then falls into the collecting bucket through the discharging hole to complete the discharging, thus realizing the full automation of the feeding of nuts and gaskets, the riveting of gaskets and nuts, and the discharging of products, with higher efficiency; 2. The frequency of the hydraulic cylinder driving the push block to move is the same as the frequency of the stepping motor driving the rotating disk to rotate. Therefore, when the rotating disk rotates, the push block drives the push rod and the riveting rod to move away from the connecting block under the drive of the hydraulic cylinder. When the discharging groove containing the nut on the rotating disk rotates to align with the pushing hole, the push block drives the push rod to pass through and slide on the inner wall of the pushing hole under the drive of the hydraulic cylinder and pushes the lowest gasket in the first track into the nut; at the same time, the riveting rod moves towards the discharging groove below the push rod until it abuts and rivets on the end face of the nut, and rivets the metal ring piece reserved on the end face of the nut inward to fix the gasket; 3. After the nut in the feeding tank rotates to align with the correction rod after the push rod pushes the gasket into the nut, the correction rod is just inserted into the nut under the push of the push block and abuts against the gasket, which can correct the position of the gasket in the nut, avoid the position deviation of the gasket in the nut, and reduce the probability of defective products.

Detailed Embodiment

[0029] The following further elaborates on the present application in conjunction with the attached Figures 1-5 drawings.

[0030] The embodiment of the present application discloses a nut riveting equipment, as Figure 1 and Figure 2As shown in the figure, it includes a frame 1, a first feeding mechanism 2 for conveying nuts, a second feeding mechanism 3 for conveying gaskets, a stamping device 4, and a rotating disk 5 provided on the frame 1. A rotating groove 6 for the rotating disk 5 to rotate is formed on the frame 1, and a stepping motor 8 for driving the rotating disk 5 to rotate is provided on the frame 1. The stepping motor 8 drives the rotating disk 5 to rotate at a set frequency and angle. A plurality of material placing grooves 7 are evenly arranged on the circumference of the rotating disk 5, and the nuts are placed in the material placing grooves 7.

[0031] As Figure 1 and Figure 2 shown in the figure, the first feeding mechanism 2 includes a first vibrating disk 11 and a first track 12, and the second feeding mechanism 3 includes a second vibrating disk 13 and a second track 14. The first feeding mechanism 2 and the second feeding mechanism 3 have the same principle, and the first feeding mechanism 2 is taken as an example in this embodiment for elaboration. The first vibrating disk 11 is both a storage device for storing nuts and a conveying device for conveying nuts. The first vibrating disk 11 continuously rotates on the frame 1 to arrange and transport the nuts therein into the first track 12. The cross-sectional width and thickness of the first track 12 only allow a single nut to exist. The top end of the first track 12 is connected to the first vibrating disk 11, and the bottom end lower surface of the first track 12 is opened to align with the uppermost material placing groove 7 on the rotating disk 5. Whenever the material placing groove 7 rotates to align with the bottom end of the first track 12, the lowermost nut in the first track 12 drops into the material placing groove 7. When the rotating groove 6 rotates out of the first track 12, the side of the rotating disk 5 abuts against the nut to prevent the nut from falling until the rotating groove 6 rotates to align with the bottom end of the first track 12 next time. The difference between the first feeding mechanism 2 and the second feeding mechanism 3 lies in the position settings of the first track 12 and the second track 14. The first track 12 and the second track are on the frame 1 and are both arranged in the vertical direction. The bottom end of the first track 12 aligns with the material placing groove 7 on the rotating disk 5 in the vertical direction; the bottom end position of the second track 14 is slightly lower than the bottom end position of the first track 12, and the second track 14 protrudes outward relative to the first track 12. At this time, the bottom side wall of the second track 14 abuts against the rotating disk 5, and the lowermost gasket in the second track 14 aligns with the slightly inclined material placing groove 7 on the rotating disk 5.

[0032] As Figure 2 and Figure 3As shown in the figure, the stamping device 4 includes a push rod 15, a correction rod 20, a riveting rod 16, a push block 17, and a hydraulic cylinder 18 that drives the movement of the push block 17. The hydraulic cylinder 18 is installed on the frame 1. The push block 17 is fixedly welded to the piston of the hydraulic cylinder 18. The push rod 15, the correction rod 20, and the riveting rod 16 are all fixedly welded to a side wall of the push block 17 close to the rotating disk 5. A push hole 19 is horizontally formed on the bottom side wall of the second track 14. The push hole 19 penetrates through the thickness direction of the second track 14 and is aligned with the feeding groove 7 containing nuts. The operating frequency of the hydraulic cylinder 18 is consistent with the frequency of the stepping motor 8, so that the moving frequency of the block is consistent with the rotating frequency of the rotating disk 5. The push block 17 reciprocally moves towards the rotating disk 5 under the drive of the hydraulic cylinder 18, causing the push rod 15 to continuously pass through the push hole 19 and push the gasket into the nut. At the same time, the correction rod 20 is inserted into the nut in the feeding groove 7 closest to the lower side of the push rod 15 and abuts against the gasket to correct the position of the gasket in the nut, avoid the position deviation of the gasket in the nut, and reduce the probability of defective products. The riveting rod 16 is aligned with the feeding groove 7 where the nut with the gasket is located below the correction rod 20. The riveting rod 16 abuts against the end face of the nut and rivets the metal sheet reserved on the end face of the nut inward to fix the gasket.

[0033] As Figure 1 and Figure 2 shown, a material taking part 21 is fixedly installed on the frame 1 by bolts. The material taking part 21 is located above the rotating groove 6 and slides relative to the rotating disk 5. The end of the material taking part 21 abuts against the peripheral side wall of the nut close to the lowest end of the rotating groove 6. An outlet 22 is formed on the bottom inner wall of the rotating groove 6. An outlet hole 9 is formed on the frame 1 below the rotating disk 5. The outlet 22 is located above the outlet hole 9. A collecting bucket 10 for receiving finished products is placed at the other end of the outlet hole 9. When the nut after being riveted by the stamping device 4 follows the feeding groove 7 to rotate to the bottom of the rotating disk 5 and abuts against the material taking part 21, when the rotating disk 5 continues to rotate, the nut is separated from the feeding groove 7 under the relative pushing of the material taking part 21 and falls off from the feeding groove 7 through the outlet 22 and drops into the outlet hole 9, so as to take the completed product off the rotating disk 5, improve the discharging efficiency, reduce the possibility that the nut is stuck in the feeding groove 7 and does not fall off, and further realize the full automation of the feeding of nuts and gaskets, the riveting of gaskets and nuts, and the discharging of products, with higher efficiency.

[0034] As Figure 3 and Figure 4 shown, and in combination with Figure 5As shown in the figure, a bracket 23 is fixedly welded on the side wall of the bottom of the second track 14 close to the push rod 15. An oil pipe 24 is fixedly installed on the bracket 23. The oil pipe 24 stores lubricating oil. The oil pipe 24 belongs to a metering oil pipe 24, and a fixed and small amount of lubricating oil is dripped out each time. The oil pipe 24 is vertically placed and is directly above the push rod 15. A piston rod 25 is slidably connected in the oil pipe 24. The frame 1 is provided with a driving assembly 26 for driving the piston rod 25 to move, and the oil pipe 24 is provided with a reset assembly 27 for resetting the piston rod 25. The driving assembly 26 includes a driving wheel 28, a driven wheel 29, a chain 30, a first rotating rod 31, a second rotating rod 32, a bevel gear set 33, a worm 34, a worm gear 35 and a cam 36. An installation groove is formed in the frame 1, and the stepping motor 8 is fixedly installed in the installation groove. The first rotating rod 31 and the second rotating rod 32 are both cylindrical, and their central axes are both arranged horizontally. The first rotating rod 31 is located on the right side of the second track 14 and rotatably penetrates through the frame 1 and is in the installation groove. The driving wheel 28 is fixedly sleeved on the rotating shaft of the stepping motor 8, and the driven wheel 29 is fixedly sleeved on the first rotating rod 31. The driving wheel 28 drives the driven wheel 29 through the chain 30.

[0035] As Figure 5 shown, the second rotating rod 32 rotates on the outer side wall of the second track 14. The worm gear is fixedly sleeved on the second rotating rod 32. The cam 36 is fixedly sleeved on one end of the second rotating rod 32 away from the side wall of the second track 14. An arc plate 38 is fixedly welded to the top end of the piston rod 25. The cam 36 rotates and abuts against the inner wall of the arc plate 38. A fixing frame 37 is fixedly welded on the second track 14. The worm 34 is horizontally arranged and rotatably penetrates through the fixing frame 37. One end of the worm 34 meshes with the worm gear 35. A telescopic groove 41 is formed at the other end of the worm 34. A sliding rod 42 slides in the telescopic groove 41. The sliding rod 42 and the first rotating rod 31 are connected through the bevel gear set 33. A first jack 43 and a second jack 44 are formed on the sliding rod 42. A connecting hole 45 is formed on the worm 34. The connecting hole 45 is aligned with the first jack 43 or the second jack 44. A fixing pin 46 is inserted into the first connecting hole 45.

[0036] As Figure 4 and Figure 5As shown, the reset assembly 27 includes a reset block 40 and a reset spring 39. The reset block 40 is in the shape of a cuboid and is fixedly welded to the piston rod 25. The reset spring 39 is arranged in the vertical direction and its two ends are respectively fixedly welded to the upper end surface of the oil pipe 24 and the lower end surface of the reset plate. When lubricating oil needs to be added to the push rod 15, the staff pulls the sliding rod 42 to move out of the telescopic groove 41, aligns the first jack 43 with the connection hole 45, and inserts and fixes the fixing pin 46. At this time, the sliding rod 42 and the first rotating rod 31 are connected through the bevel gear set 33. When the stepping motor 8 drives the rotating disk 5 to rotate, the driving wheel 28 also rotates. The driving wheel 28 rotates to drive the driven wheel 29 to rotate through the chain 30. The driven wheel 29 rotates to drive the first rotating rod 31 to rotate. The first rotating rod 31 rotates to drive the worm 34 to rotate through the bevel gear set 33 and the sliding rod 42. The worm 34 rotates to drive the second rotating rod 32 to rotate through the worm gear 35. The second rotating rod 32 rotates to drive the cam 36 to rotate. When the protruding end of the cam 36 rotates to abut against the arc disk 38, it pushes the piston rod 25 downward to move, so as to push the lubricating oil out of the oil pipe 24 and drip onto the push rod 15, so that the lubricating oil slowly flows on the push rod 15 to wrap its side wall, thereby reducing the friction and temperature between the push rod 15 and the inner wall of the push hole 19. When the protruding end of the cam 36 rotates away from the arc disk 38, the reset plate pushes the arc disk 38 upward under the push of the reset spring 39, so as to drive the piston rod 25 to move upward for the next push. When the lubricating oil addition to the push rod 15 is completed for a period of time, the staff removes the fixing pin 46, pushes the sliding rod 42 into the telescopic groove 41 until the second jack 44 is aligned with the connection hole 45 and inserts and fixes the fixing pin 46. At this time, the connection between the first rotating rod 31 and the worm 34 is disconnected and the lubricating oil addition stops.

[0037] The implementation principle of the embodiment of the present application is as follows: When the equipment is started, the rotating disk 5 rotates under the action of the stepping motor 8. At the same time, the material nut is conveyed to the discharging groove 7 of the rotating disk 5 through the first feeding mechanism 2. The discharging groove 7 receiving the nut continues to rotate until it is aligned with the lowest gasket in the second feeding mechanism 3. Subsequently, under the action of the stamping device 4, the gasket is riveted into the nut. The rotating disk 5 continues to rotate to the discharging hole 9 under the action of the stepping motor 8, so that the riveted nut falls from the discharging groove 7 into the discharging hole 9 and falls into the collecting bucket 10 through the discharging hole 9 to complete the discharging, thereby realizing the full automation of the feeding of nuts and gaskets, the riveting of gaskets and nuts, and the discharging of products, with higher efficiency.

[0038] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
