Description

Technical Field

[0001] The present invention relates to the field of fastener manufacturing, in particular to an auxiliary positioning device for fastener manufacturing. Background Art

[0002] In the fastener manufacturing industry, whether processing standard parts like bolts and nuts or various special-shaped fasteners, precise positioning and stable clamping are essential. Positioning devices, as key auxiliary equipment in fastener processing, directly impact the accuracy and efficiency of subsequent processes like tapping, drilling, and welding. Therefore, they play a crucial role in automated production lines and batch processing scenarios.

[0003] Currently, common fastener positioning devices on the market mostly use pneumatic or hydraulically driven clamping structures, clamping the workpiece with symmetrically arranged jaws. However, these devices have many limitations in practical applications: On the one hand, for regularly shaped fasteners (such as hexagonal nuts and cylindrical bolts), while traditional devices can achieve basic positioning, the clamping force is often difficult to accurately control. Excessive force can easily damage the workpiece surface, or insufficient force can cause loosening during processing, affecting machining accuracy. On the other hand, when faced with special-shaped fasteners or irregular workpieces, traditional symmetrical jaws cannot adapt to the workpiece shape, often resulting in positioning offset and unstable clamping. Frequent fixture replacement or manual adjustment is required, which not only reduces production efficiency but also increases labor costs.

[0004] Furthermore, existing positioning devices lack compatibility. Fasteners of varying sizes and materials often require specific positioning components, making it difficult to meet diverse production needs. While some devices offer some degree of adjustment, the process is complex, and clamping force diminishes with workpiece deformation and device wear. In high-speed machining environments, vibration further exacerbates clamping force instability, leading to frequent "false clamping" and, in severe cases, even safety incidents.

[0005] At the same time, traditional positioning devices have a low level of automation, and most require manual assistance to place the workpiece and initiate the clamping action, which is incompatible with the automated and intelligent trends of modern smart manufacturing. In the pursuit of efficient production, how to quickly, accurately, and stably position and clamp fasteners of different shapes and sizes while also ensuring flexible adjustment and good compatibility has become a technical challenge that the fastener manufacturing industry urgently needs to address. Therefore, the development of an auxiliary positioning device with strong adaptability, stable clamping, high precision, and easy integration into automated production lines has important practical significance and application value. Summary of the Invention

A movable groove is opened on the upper surface of the fixed seat near each of the threaded rods, and the top of the movable block passes through the interior of the movable groove on the corresponding side and is fixedly installed with a positioning clamping seat, and the inner side of the positioning clamping seat is provided with There is a clamping block, and cross frames are fixedly installed on both sides of the interior of the positioning clamping seat, and L-shaped rotating frames are movably installed at the ends of the cross frames, and fiberglass spring plates are fixedly installed inside the cross frames, and the ends of the fiberglass spring plates extend to the interior of the L-shaped rotating frames on the corresponding sides, and pressure rollers are fixedly installed inside the L-shaped rotating frames, and the inner ends of the pressure rollers are in contact with the surfaces of the fiberglass spring plates on the corresponding sides, and connecting rods are movably installed on the outer ends of the L-shaped rotating frames, and pressure rods are movably installed on the ends of the connecting rods, and the ends of the pressure rods extend to the outside of the clamping block and are fixedly installed on one end of the clamping block on the corresponding side.

[0008] Preferably, a mounting seat is provided below the fixed seat, and three lower hinge supports are fixedly installed on the surface of the mounting seat, and electric cylinders are movably installed on both sides of the top of the lower hinge supports, and three upper hinge supports are fixedly installed on the bottom end of the fixed seat, and the ends of the electric cylinders on the corresponding sides are movably installed on both sides of the bottom ends of the upper hinge supports on the corresponding sides, and a number of mounting holes are also provided on the surface of the mounting seat.

[0009] Preferably, the inner ends of the threaded rods are fixedly mounted with short shafts, the outer diameters of the short shafts are provided with driven bevel gears and the inner ends of the driven bevel gears are threadedly connected to the tops of the driving bevel gears, and the outer ends of the driven bevel gears are connected to the outer diameters of the short shafts on the corresponding sides through compression springs.

[0010] Preferably, a chuck is fixedly installed on the inner outer diameter of the short shaft, and a plurality of round head pins are fixedly installed on the end of the chuck close to the driven bevel gear. A plurality of limiting grooves are provided on the end of the driven bevel gear close to the chuck, and the ends of the round head pins are arranged inside the limiting grooves on the corresponding sides.

[0011] Preferably, a three-phase asynchronous motor is fixedly mounted on the bottom end of the fixing seat, and a driving end of the three-phase asynchronous motor extends into the interior of the fixing seat and is fixedly mounted on one end of the rotating shaft.

[0012] Preferably, an adjusting screw is movably installed in the inner middle part of the positioning clamping seat, and an interference frame is threadedly connected to the outer diameter of the adjusting screw, and the two ends of the interference frame respectively interfere with the inner end surfaces of the two glass fiber spring plates, and guide rods are fixedly installed on both sides of the interior of the positioning clamping seat close to the adjusting screw, and the outer diameters of the guide rods are movably set on both sides of the inner side of the interference frame on the corresponding side, and one end of the adjusting screw extends to the end of the positioning clamping seat and is fixedly installed with an adjusting knob.

[0013] Preferably, a photoelectric sensor is fixedly mounted on the middle portion of the top end of the fixing seat.

[0014] The present invention provides an auxiliary positioning device for fastener manufacturing, which has the following beneficial effects: 1. This invention utilizes the cooperation of a driving bevel gear and a driven bevel gear to drive the synchronous movement of four positioning clamping blocks, enabling rapid centering and clamping of regularly shaped fastener workpieces. For irregularly shaped workpieces, the release mechanism of a compression spring, a round pin, and a stop groove allows the clamping blocks not in contact with the workpiece to continue moving until clamping is complete, while those already in contact stop rotating. This ensures precise positioning regardless of the workpiece's shape, significantly improving adaptability to diverse workpiece shapes.

[0015] 2. After the clamping block contacts the workpiece, the L-shaped turret, pressure roller, and fiberglass spring plate work together to achieve clamping, utilizing the reaction force generated by the bending of the fiberglass spring plate. The fiberglass spring plate's ample elasticity ensures adequate clamping force while preventing damage to the workpiece surface due to excessive force. Simultaneously, the relative sliding of the pressure roller on the fiberglass spring plate changes the lever arm, compensating for the increase in elasticity with bending, ensuring uniform clamping force throughout the entire process and effectively preventing "false clamping." Furthermore, even in the vibration environment of high-speed machining, the clamping force is not easily attenuated, preventing workpiece loosening and ensuring machining stability.

[0016] 3. The present invention drives the adjusting screw to rotate by rotating the adjusting knob, moves the contact frame under the limit of the guide rod, changes the support point of the fiberglass spring plate, and then adjusts its elastic force when bending, realizes the active modification of the clamping force, and can adapt to the clamping requirements of fasteners of different materials and sizes.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example: Please see the attached Figure 1 -Attached Figure 5 , an embodiment of the present invention provides an auxiliary positioning device for fastener manufacturing, such as Figure 1As shown, it includes a fixed base 1, which serves as the basic bearing structure of the entire device and provides an installation support platform for various components. Its internal hollow design is convenient for accommodating transmission components such as a rotating shaft 7 and an active bevel gear 8. A rotating shaft 7 is movably installed in the middle of the fixed base 1. The rotating shaft 7 can rotate freely around its own axis and is a key component for transmitting power. A driving bevel gear 8 is fixedly installed on the outer diameter of the middle part of the rotating shaft 7. The driving bevel gear 8 rotates synchronously with the rotating shaft 7 and drives the driven bevel gear 14 to rotate through the gear meshing action. Four threaded rods 9 are evenly and movably installed on the inner side wall of the fixed base 1. The four threaded rods 9 are symmetrically distributed in a ring to ensure balanced clamping force on the workpiece. The threaded rod 9 can rotate on the inner wall of the fixed seat 1, and a movable block 10 is threadedly connected on its outer diameter. The movable block 10 and the threaded rod 9 realize linear motion conversion through threaded cooperation. A movable groove 11 is provided on the upper surface of the fixed seat 1 near each threaded rod 9. The movable groove 11 limits the movement direction of the movable block 10 and prevents the movable block 10 from rotating with the threaded rod 9. The top of the movable block 10 passes through the interior of the corresponding side movable groove 11 and is fixedly installed with a positioning clamping seat 12. The movable block 10 drives the positioning clamping seat 12 to move along the direction of the movable groove 11. The inner side of the positioning clamping seat 12 is provided with a clamping block 20, which is in direct contact with the workpiece To achieve the clamping action, cross frames 21 are fixedly installed on both sides of the interior of the positioning clamping seat 12, and the cross frames 21 provide installation supports for the L-shaped rotating frame 22 and the fiberglass spring plate 23. The ends of the cross frames 21 are movably installed with L-shaped rotating frames 22, and the L-shaped rotating frames 22 can rotate around the connection point with the cross frames 21. The interior of the cross frames 21 is fixedly installed with fiberglass spring plates 23, and the ends of the fiberglass spring plates 23 extend to the interior of the L-shaped rotating frames 22 on the corresponding sides. The fiberglass spring plates 23 have good elasticity and toughness, and the reaction force generated by their bending provides power for clamping. The interior of the L-shaped rotating frames 22 is fixedly installed with pressure rollers 26, and the inner ends of the pressure rollers 26 abut against the corresponding side fiberglass spring plates. On the surface of the spring plate 23, the pressure roller 26 can roll on the surface of the glass fiber spring plate 23 to reduce the friction between the two. At the same time, the glass fiber spring plate 23 is bent when the L-shaped rotating frame 22 rotates. The outer ends of the L-shaped rotating frame 22 are movably installed with connecting rods 24. The connecting rods 24 play a force transmission role, transmitting the force exerted on the clamping block 20 to the L-shaped rotating frame 22. The ends of the connecting rods 24 are movably installed with pressure rods 25. The pressure rods 25 connect the clamping block 20 and the connecting rods 24. The ends of the pressure rods 25 extend to the outside of the clamping block 20 and are fixedly installed on one end of the clamping block 20 on the corresponding side. When the clamping block 20 contacts the workpiece, the L-shaped rotating frame 22 is driven to move through the pressure rods 25 and the connecting rods 24.

[0021] In this embodiment, a mounting base 2 is provided below the fixing base 1. The mounting base 2 is a component connecting the device to the processing table. The bottom end of the fixing base 1 is connected to the electric cylinder 4 through an upper hinge support 5 to achieve the posture adjustment of the fixing base 1. Three lower hinge supports 3 are fixedly installed on the surface of the fixing base 2. The lower hinge supports 3 provide hinge support points for the bottom of the electric cylinder 4 to ensure that the electric cylinder 4 can flexibly adjust the angle. Electric cylinders 4 are movably installed on both sides of the top of the lower hinge support 3. The electric cylinder 4 serves as a driving component, and drives the fixing base 1 to achieve translation, rotation and tilt through telescopic movement. For actions such as tilting, three upper hinge supports 5 are fixedly installed at the bottom of the fixed base 1, and the upper hinge supports 5 are movably connected to the top of the electric cylinder 4 to transmit the power of the electric cylinder 4 to the fixed base 1. The ends of the electric cylinders 4 on the corresponding sides are movably installed on both sides of the bottom ends of the upper hinge supports 5 on the corresponding sides. This connection method enables the telescopic movement of the electric cylinder 4 to be effectively converted into posture changes of the fixed base 1. A number of mounting holes 6 are also provided on the surface of the mounting base 2. The mounting holes 6 are used to fix the device on the processing table by means of bolts and other connecting parts to ensure that the device is stable and reliable during operation.

[0022] Furthermore, the inner ends of the threaded rods 9 are fixedly mounted with short shafts 13, which connect the threaded rods 9 and the driven bevel gear 14, transmitting the rotational motion of the driven bevel gear 14 to the threaded rods 9. The outer diameters of the short shafts 13 are provided with driven bevel gears 14, and the inner ends of the driven bevel gears 14 are threadedly connected to the top of the active bevel gear 8. The driven bevel gears 14 mesh with the active bevel gear 8 and rotate under the drive of the active bevel gear 8. The outer ends of the driven bevel gears 14 are connected to the outer diameters of the short shafts 13 on the corresponding sides through compression springs 15. The compression springs 15 provide axial pressure for the driven bevel gear 14, so that the round head pin 17 and the limit groove 18 remain in an engaged state. When the clamping block 20 contacts the workpiece, the threaded rod 9 stops rotating, and the compression spring 15 is compressed when the driven bevel gear 14 continues to rotate, thereby realizing the disengagement of the round head pin 17 from the limit groove 18.

[0023] Furthermore, a chuck 16 is fixedly installed on the inner outer diameter of the short shaft 13, and the chuck 16 rotates synchronously with the short shaft 13. Several round pins 17 are fixedly installed on the end of the chuck 16 close to the driven bevel gear 14. The round pins 17 cooperate with the limit grooves 18 to realize the linkage or disengagement of the driven bevel gear 14 and the chuck 16. Several limit grooves 18 are provided on the end of the driven bevel gear 14 close to the chuck 16. The limit grooves 18 provide engaging space for the round pins 17, and the ends of the round pins 17 are arranged inside the corresponding side limit grooves 18. When the driven bevel gear 14 rotates synchronously with the chuck 16, the round pins 17 are stuck in the limit grooves 18; when the threaded rod 9 stops rotating and the driven bevel gear 14 continues to rotate, the round pins 17 disengage from the limit grooves 18, compressing the compression spring 15, and then again engage in the next limit groove 18 under the action of the spring force, realizing the disengagement and engagement cycle.

[0024] Specifically, when the shape of the workpiece is irregular, two opposing clamping blocks 20 will first contact the workpiece, while the other two clamping blocks 20 have not yet contacted the surveying instrument. At this time, the three-phase asynchronous motor 19 continues to drive the rotating shaft 7 to rotate, and the active bevel gear 8 will continue to drive all the driven bevel gears 14 to rotate, so that the two clamping blocks 20 that have not contacted the surveying instrument continue to move inward until they contact the workpiece to complete the clamping action, and the threaded rods 9 of the two clamping blocks 20 that previously contacted the workpiece will stop rotating, and the driven bevel gears 14 on their inner side will compress the compression spring 15 when rotating, causing the round head pin 17 and the limit groove 18 to continuously disengage and engage, thereby preventing the threaded rod 9 from rotating with the rotation of the driven bevel gear 14, thereby achieving precise positioning and clamping of workpieces of various shapes.

[0025] Furthermore, a three-phase asynchronous motor 19 is fixedly installed at the bottom end of the fixed base 1, and the driving end of the three-phase asynchronous motor 19 extends to the interior of the fixed base 1 and is fixedly installed on one end of the rotating shaft 7. The three-phase asynchronous motor 19 provides a power source for the device, and its driving end drives the rotating shaft 7 to rotate, and then drives each threaded rod 9 to rotate through gear transmission, thereby realizing the movement of the positioning clamping base 12.

[0026] The adjusting screw 27 is fixedly mounted on the inner middle part of the positioning clamping seat 12, and the adjusting screw 27 can be rotated in the positioning clamping seat 12, and the interference frame 28 is moved by the threaded transmission. The outer diameter of the adjusting screw 27 is threadedly connected to the interference frame 28, and the two ends of the interference frame 28 respectively contact the inner end surface of the two fiberglass spring plates 23. The interference frame 28 is used to change the support point position of the fiberglass spring plate 23, thereby adjusting the elastic force when bending.

[0027] Specifically, when the clamping block 20 contacts the workpiece, the clamping block 20 will push the extrusion rod 25 outward and drive the L-shaped rotating frame 22 to rotate and bend through the connecting rod 24. When the L-shaped rotating frame 22 bends, the glass fiber spring plate 23 will be bent by the pressure roller 26, and the reaction generated by the bent glass fiber spring plate 23 will apply pressure to the clamping block 20 to achieve clamping. Since the elastic force of the glass fiber spring plate 23 is large, while ensuring sufficient clamping force, the surface of the workpiece will not be damaged due to excessive clamping force. In addition, when the glass fiber spring plate 23 bends, the pressure roller 26 will slide relatively on its surface, causing the force arm of the bent glass fiber spring plate 23 to change, thereby compensating for the elastic force that continues to increase as the glass fiber spring plate 23 continues to bend, so that the clamping force remains uniform throughout the process, avoiding the "virtual clamping" situation, and also avoiding the loosening problem caused by the clamping force attenuating with vibration during subsequent high-speed processing.

[0028] In addition, the adjusting screw 27 can be rotated by rotating the adjusting knob 30, and the interference frame 28 can be moved by using the limiting function of the guide rod 29. When the interference frame 28 is displaced, the support point position of the fiberglass spring plate 23 will change. When the support point position changes, the elastic force generated during bending will also change, thereby changing the clamping force of the clamping block 20, which is convenient for active modification according to the clamping requirements of different workpieces.

[0029] Furthermore, a photoelectric sensor 31 is fixedly installed in the middle of the top of the fixed seat 1. The photoelectric sensor 31 can sense the workpiece placed in the middle of the fixed seat 1. When the workpiece is detected, the three-phase asynchronous motor 19 is automatically triggered to start, realizing the automatic clamping action of the device and improving the convenience and efficiency of operation.

[0030] Working principle: First, fix the device on the processing table through the mounting hole 6, and then place the fastener workpiece to be processed, such as bolts and nuts, on the middle of the fixed seat 1 manually or automatically. At this time, the photoelectric sensor 31 senses the position of the workpiece and starts the three-phase asynchronous motor 19. The three-phase asynchronous motor 19 drives the rotating shaft 7 to rotate, driving the active bevel gear 8 to rotate. The rotating active bevel gear 8 will drive all the driven bevel gears 14 to rotate, thereby driving all the short shafts 13 and the threaded rod 9 to rotate. When the threaded rod 9 rotates, it will engage with the movable block 10 on the outer diameter and use the limiting effect of the movable groove 11 to drive all the positioning clamping seats 12 and the clamping blocks 20 to move inward synchronously, thereby clamping the workpiece. When the shape of the workpiece is irregular At this time, two of the opposite clamping blocks 20 will first contact the workpiece, while the other two clamping blocks 20 have not yet contacted the surveying instrument. At this time, the three-phase asynchronous motor 19 continues to drive the rotating shaft 7 to rotate, and the active bevel gear 8 will continue to drive all the driven bevel gears 14 to rotate, so that the two clamping blocks 20 that have not contacted the surveying instrument continue to move inward until they contact the workpiece to complete the clamping action, and the threaded rods 9 of the two clamping blocks 20 that have previously contacted the workpiece will stop rotating, and the driven bevel gears 14 on their inner side will compress the compression spring 15 when rotating, causing the round head pin 17 and the limit groove 18 to continuously disengage and engage, thereby preventing the threaded rod 9 from rotating with the rotation of the driven bevel gear 14, thereby achieving precise positioning of workpieces of various shapes. The clamping work is carried out in the position. In addition, when the clamping block 20 contacts the workpiece, the clamping block 20 will push the extrusion rod 25 outward and drive the L-shaped rotating frame 22 to rotate and bend through the connecting rod 24. When the L-shaped rotating frame 22 bends, the fiberglass spring plate 23 will be bent by the pressure roller 26, and the reaction generated by the bent fiberglass spring plate 23 will be used to apply pressure to the clamping block 20 to achieve the clamping work. Since the elastic force of the fiberglass spring plate 23 is large, while ensuring sufficient clamping force, the surface of the workpiece will not be damaged due to excessive clamping force. In addition, when the fiberglass spring plate 23 bends, the pressure roller 26 will slide relatively on its surface, causing the force arm of the bent fiberglass spring plate 23 to change, thereby compensating for the elastic force that continues to increase as the fiberglass spring plate 23 continues to bend. The force is used to keep the clamping force uniform throughout the whole process, avoiding the situation of "false clamping". At the same time, it also avoids the loosening problem caused by the attenuation of the clamping force as the vibration during the subsequent high-speed processing. Finally, the adjusting screw 27 can be driven to rotate by rotating the adjusting knob 30, and the limiting effect of the guide rod 29 is used to drive the contact frame 28 to move. When the contact frame 28 is displaced, the support point position of the fiberglass spring plate 23 will be changed. When the support point position changes, the elastic force generated during bending will also change, thereby changing the clamping force of the clamping block 20, which is convenient for active modification according to the clamping requirements of different workpieces. Finally, through the coordinated extension and contraction of the six electric cylinders 4 on the mounting seat 2, the fixed seat 1 can be realized. Short-distance translation, rotation and tilting movements in the horizontal and vertical directions,It is convenient for subsequent tapping, punching, welding and other processing operations on fasteners.
