Description

Technical Field

[0001] This utility model relates to the field of upper nuts, specifically a plug-in loading component for upper nut structures. Background Technology

[0002] In the component loading process of industrial production, the automated feeding and precise positioning of nuts are crucial for ensuring production efficiency and product quality. Currently, some production scenarios still rely on manual nut feeding, which not only suffers from low feeding efficiency and high labor intensity, but is also prone to nut positioning deviations due to human error, thus affecting the accuracy of component loading and increasing product defect rates. Even with automated feeding equipment, existing equipment has many shortcomings: Firstly, the feeding mechanism lacks stable support and vibration buffer structures, and the vibration generated by the power components during operation can easily cause the overall structure to shake, which can not only cause nut feeding to jam or shift, but also damage equipment components and generate significant noise pollution in the working environment. Secondly, the position adjustment flexibility of the feeding track and limit components is insufficient, making it difficult to adapt to different nut specifications or different component loading requirements. During the adjustment process, the transmission accuracy is low and the limit reliability is poor, which can easily lead to component position shifts after adjustment, failing to guarantee the stability of subsequent loading processes.

[0003] In addition, the internal frictional resistance of the feeding track is relatively large, and the track is prone to wear after long-term use. This not only shortens the service life of the equipment, but also further aggravates the problem of uneven nut delivery, which seriously restricts the automation level and production efficiency improvement of the plug-in loading process. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plug-in loading assembly for an upper nut structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a plug-in loading assembly for an upper nut structure, including a straight vibrator base mounted on a workbench, a straight vibrator fixed at the top of the straight vibrator base, spring pieces fixed on both sides of the straight vibrator, a feeding track for feeding nuts fixed above the straight vibrator, pressure plate guide plates fixed on both ends of the feeding track, a strip groove opened inside the bottom end of the pressure plate guide plate, a guide plate support plate slidably connected inside the strip groove, the inner end face of the guide plate support plate being threadedly connected to the outer wall of the feeding track by a screw, a nut pressure plate fixed inside the top end of the guide plate support plate, a pressure plate adjustment assembly fixed at the center of both sides of the straight vibrator, an adjustment plate inside the pressure plate adjustment assembly, a top block fixed at the top of the adjustment plate, and the top block being fixedly connected to the feeding track.

[0006] Furthermore, a steel plate for reducing friction is fixed at the bottom of the feeding track, and steel plate fasteners are fixed on both sides of the bottom of the feeding track. The steel plate fasteners pass through the feeding track and are connected to the steel plate.

[0007] Furthermore, the pressure plate adjustment assembly includes a gear housing fixed at the center of the side wall of the feeding track. A drive gear is rotatably connected inside the gear housing. One side wall of the drive gear is meshed with the adjustment plate. A gear knob is fixed at one end of the drive gear shaft that passes through the gear housing.

[0008] Furthermore, the adjusting plate has teeth on the side wall near the drive gear, and the tooth pitch of the teeth is adapted to the drive gear.

[0009] Furthermore, the pressure plate adjustment assembly also includes a reset member protective shell fixed to the side wall of the gear housing. A reset member is provided inside the reset member protective shell. A gear limiting member is fixed to the end face of the reset member away from the reset member protective shell, and a limiting member pull plate is fixed to the side wall of the gear limiting member. The limiting member pull plate is slidably connected to the reset member protective shell.

[0010] Furthermore, a plug is fixed to the side wall of the gear limiting member away from the reset member, and the plug is inserted between the teeth of the drive gear. A sliding limiting rod is fixed at the center of the other side wall of the gear limiting member, and the sliding limiting rod is slidably connected to the protective shell of the reset member.

[0011] Furthermore, a strip-shaped groove is provided in the side wall of the reset component protective shell to limit the sliding trajectory of the limiting component pull plate. A through hole is provided at the center of the end face of the reset component protective shell to limit the sliding limiting rod.

[0012] The beneficial effects of this utility model are: Enhanced position adjustment flexibility: The pressure plate adjustment assembly enables flexible position adjustment of the feeding track and nut pressure plate to accommodate different nut or plug-in loading requirements. During adjustment, the limit plate is pulled to release the limit of the drive gear, and rotating the gear knob allows the drive gear to mesh with the adjustment plate, driving the top block to precisely adjust the position of the nut pressure plate. The tooth design of the adjustment plate ensures precise transmission, while the sliding limit rod and strip groove ensure smooth movement of the components during adjustment, preventing deviation. After adjustment, the reset component pushes the insertion rod of the gear limit component to engage with the drive gear teeth, achieving reliable limiting, preventing component position deviation, and ensuring the stability of the structure after adjustment.

[0013] Ensuring positioning and equipment durability: The channel size of the feeding track matches the shape of the nut, guiding it. Combined with the nut pressure plate for tightening and limiting the nut, it ensures that the nuts are neatly arranged and accurately positioned during the conveying process, providing reliable support for the subsequent plug-in loading process. The steel plate is made of wear-resistant material, which reduces wear on the feeding track and extends the service life of the equipment. The through-type connection of the steel plate fasteners facilitates the disassembly and replacement of the steel plate, reducing the difficulty of equipment maintenance. The overall structural design takes into account both production precision and equipment practicality, effectively improving the automation level and production efficiency of the plug-in loading process.

[0020] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0021] See Figures 1-5This is a schematic diagram of the structure of this utility model, which is a plug-in loading assembly for an upper nut structure. It includes a straight vibrator base 1 installed on a workbench. The straight vibrator base 1 serves as the basic support component of the entire plug-in loading structure, and is used to stably support the straight vibrator 2 and all components above it, ensuring that the overall structure will not shake or shift during operation, and providing a stable installation platform for subsequent nut delivery and processing.

[0022] A vertical vibrator 2 is fixed at the top of the base 1. As the core component for power output, the vertical vibrator 2 generates directional vibration force, which drives the nut in the feeding track 4 to move stably in a preset direction, realizing automatic feeding of the nut, replacing manual feeding, and improving conveying efficiency and stability. Springs 3 are fixed on both sides of the vertical vibrator 2. The springs 3 are made of elastic metal material. Their main function is to buffer and adjust the vibration amplitude when the vertical vibrator 2 vibrates during operation, so as to avoid excessive vibration that could damage the vertical vibrator 2 and surrounding components. At the same time, it reduces the force of vibration transmitted to the worktable and reduces the noise of the overall structure during operation.

[0023] Above the vibrator 2 is a feeding track 4 for conveying nuts. The feeding track 4 is the channel component for conveying nuts. Its internal channel size matches the shape of the nut, which can guide the nut and ensure that the nut moves stably along the inside of the track under the vibration force without deviation or jamming, thus ensuring the continuity of nut conveying. Pressure plate guide plates 5 are fixed on both ends of the feeding track 4. The pressure plate guide plates 5 serve as the mounting and guiding base components for the nut pressure plate 7. Through the strip-shaped groove at its bottom, it provides trajectory restriction for the sliding of the guide plate support plate 6, ensuring that the nut pressure plate 7 always maintains a straight direction when moving, avoiding deviation that would affect the tightening effect of the nut. The bottom end of the pressure plate guide plate 5 has a strip-shaped groove, and the guide plate support plate 6 is slidably connected inside the strip-shaped groove. The guide plate support plate 6, as the intermediate component connecting the pressure plate guide plate 5 and the feeding track 4, can not only slide along the strip-shaped groove to adjust the nut... The pressure plate 7 can also be fixed to the feeding track 4 by a screw, stably supporting the nut pressure plate 7 above the feeding track 4, ensuring the stability of the nut pressure plate 7 during operation. The inner end face of the guide plate support plate 6 is threaded to the outer wall of the feeding track 4 by a screw. The screw connection is detachable and adjustable, which facilitates the replacement or position adjustment of the nut pressure plate 7 by disassembling the guide plate support plate 6 according to the nut specifications or usage requirements. At the same time, the tightness of the threaded connection ensures that the guide plate support plate 6 and the feeding track 4 are tightly connected to avoid loosening. The nut pressure plate 7 is fixed to the inner top of the guide plate support plate 6. The nut pressure plate 7 is located above the feeding track 4. Its main function is to press and limit the nuts conveyed in the feeding track 4, preventing the nuts from popping out of the track due to large vibration amplitude during vibration conveying. At the same time, it ensures that the nuts are kept in a neat arrangement in the track, providing nuts with precise positioning for the subsequent plug-in loading process.

[0024] A pressure plate adjustment assembly is fixed at the center of both sides of the straight vibrator 2. The pressure plate adjustment assembly is the core component for adjusting the position of the feeding track 4. By moving the internal adjustment plate 13, the feeding track 4 can be adjusted up and down or back and forth to adapt to different specifications of nuts or different plug-in loading requirements, ensuring that the feeding track 4 is accurately connected with the subsequent processing mechanism. The pressure plate adjustment assembly has an internal adjustment plate 13. As a key component for power transmission and position adjustment, the adjustment plate 13, through meshing with the drive gear 11, converts the rotational motion of the drive gear 11 into its own linear motion, thereby driving the top block 14 fixed at the top and the feeding track 4 to achieve position adjustment. The top block 14 is fixed at the top of the adjustment plate 13. The top block 14 serves as a transition component connecting the adjustment plate 13 and the feeding track 4, and at the same time, it stably transmits the motion of the adjustment plate 13 to the feeding track 4, ensuring that the feeding track 4 remains stable during the adjustment process without tilting or shaking. The top block 14 is fixedly connected to the feeding track 4. This fixed connection ensures that there is no relative displacement between the top block 14 and the feeding track 4, so that when the adjustment plate 13 drives the feeding track 4 to adjust its position through the top block 14, the feeding track 4 can accurately respond to the adjustment action and achieve the expected position adjustment effect.

[0025] A steel plate 8 is fixed to the bottom of the inner side of the feeding track 4 to reduce friction. The steel plate 8 is made of a smooth, wear-resistant metal material. Its placement on the bottom of the inner side of the feeding track 4 converts the sliding friction between the nut and the feeding track 4 into sliding friction between the nut and the steel plate 8, significantly reducing friction and resistance during nut transport. This allows the nut to move more smoothly under vibration and prevents damage to the bottom of the inner side of the feeding track 4 due to long-term friction, extending the track's service life. Steel plate fasteners 9 are fixed to both sides of the bottom of the feeding track 4. These fasteners 9, as components for fixing the steel plate 8, can tightly secure... The bottom end of the feeding track 4 and the edge of the steel plate 8 are closely fitted. The steel plate 8 is connected to the feeding track 4 through the feeding track 4, and is firmly fixed to the bottom end of the feeding track 4. This prevents the steel plate 8 from shifting or falling off due to friction or vibration during nut conveying, and ensures that the steel plate 8 always plays a drag-reducing role. The steel plate fixing part 9 is connected to the steel plate 8 through the feeding track 4. This through connection method can enhance the fixing force of the steel plate fixing part 9 on the steel plate 8, so that the steel plate 8 and the feeding track 4 form a whole, avoiding gaps between the two that would cause the nut to get stuck. It also facilitates the subsequent disassembly and replacement of the steel plate 8, reducing the difficulty of maintenance.

[0026] The pressure plate adjustment assembly includes a gear housing 10 fixed at the center of the side wall of the feeding track 4. The gear housing 10 serves as a protective and mounting component for the drive gear 11. Its internal space matches the size of the drive gear 11, stably enclosing it and preventing external dust and impurities from affecting its transmission performance. It also prevents accidental contact with the drive gear 11 during adjustment, thus providing a safe and stable working environment for the drive gear 11. The drive gear 11 is rotatably connected inside the gear housing 10. As the core power transmission component of the pressure plate adjustment assembly, the drive gear 11, through its rotational motion, drives the adjustment plate 13 using the gear meshing principle, thereby adjusting the position of the nut pressure plate 7. Its tooth design matches the teeth of the adjustment plate 13, ensuring precise power transmission without slippage during transmission. One side wall of the drive gear 11 meshes with the adjustment plate 13. This meshing connection efficiently converts the rotational motion of the drive gear 11 into the linear motion of the adjustment plate 13. The operator only needs to rotate the gear knob 12 to drive the drive gear... Rotating wheel 11 allows for the smooth movement of adjusting plate 13, thereby precisely adjusting the position of nut pressure plate 7. A gear knob 12 is fixed to one end of the shaft of drive gear 11, which passes through gear housing 10. The gear knob 12 serves as a manual operating component for controlling the rotation of drive gear 11. Its surface typically has anti-slip textures for easy gripping and force application. Rotating the gear knob 12 easily drives drive gear 11, thereby controlling the adjustment direction and amplitude of adjusting plate 13 and feeding track 4. The operation is convenient and easy to control. The side wall of the adjusting plate 13 near the drive gear 11 is provided with teeth. The teeth are the key structure for the meshing transmission between the adjusting plate 13 and the drive gear 11. The tooth shape and tooth pitch are adapted to the drive gear 11 to ensure that the two can fit tightly when meshing, and there will be no tooth misalignment or slippage. This allows the adjusting plate 13 to achieve corresponding linear movement according to the rotation direction and angle of the drive gear 11. The tooth pitch is adapted to the drive gear 11. The adapted tooth pitch design ensures that the adjusting plate 13 moves a corresponding distance for every tooth pitch rotated by the drive gear 11.

[0027] The pressure plate adjustment assembly also includes a reset member protective shell 15 fixed to the side wall of the gear housing 10. The reset member protective shell 15 serves as the mounting and protective shell for components such as the reset member 18 and the gear limiting member 16. Its interior has matching mounting spaces for each component, allowing these components to be neatly housed internally, preventing damage from external environmental factors, and providing stable space for the movement of each component to ensure normal function. The reset member 18 is housed inside the reset member protective shell 15. The reset member 18 typically uses a spring or other component with elastic reset function. In its natural state, it applies a continuous thrust to the gear limiting member 16, keeping the gear limiting member 16 in a toothed engagement with the drive gear 11, thus achieving the limiting and fixing of the drive gear 11. When necessary... When adjusting the drive gear 11, the limit plate 17 is pulled to compress the reset piece 18, thereby releasing the limit on the drive gear 11. After adjustment, the reset piece 18 returns to its original state, and the gear limit piece 16 is pushed again to limit the drive gear 11, ensuring that the position of the drive gear 11 is stable after adjustment. The end face of the reset piece 18 away from the reset piece protective shell 15 is fixed with a gear limit piece 16 that presses against it. The gear limit piece 16, as a component that restricts the rotation of the drive gear 11, is inserted between the teeth of the drive gear 11 through a plug fixed to its side wall. It can prevent the drive gear 11 from rotating on its own in the non-adjusted state, thereby fixing the position of the adjusting plate 13 and the nut pressure plate 7, avoiding the displacement of the nut pressure plate 7 due to vibration or external force, and ensuring the stability of the plug-in loading process.

[0028] A limiting plate 17 is fixed to the side wall of the gear limiting member 16. The limiting plate 17 serves as a component for the operator to control the movement of the gear limiting member 16. It extends to the outside of the reset member protective shell 15, making it easy for the operator to hold and pull. By pulling the limiting plate 17, the gear limiting member 16 can be driven to compress the reset member 18, causing the insertion rod to disengage from the teeth of the drive gear 11, releasing the limitation on the drive gear 11, and providing conditions for the rotation adjustment of the drive gear 11. The limiting plate 17 is slidably connected to the reset member protective shell 15. The sliding connection ensures that when the limiting plate 17 drives the gear limiting member 16 to move, it always slides along a fixed trajectory, avoiding deviation that would prevent the insertion rod from disengaging or inserting into the teeth of the drive gear 11. At the same time, it ensures that the movement of the limiting plate 17 is smooth and the operation is seamless.

[0029] A rod is fixed to the side wall of the gear limiting component 16 away from the reset component 18. The rod is the core structure for limiting the drive gear 11 by the gear limiting component 16. Its size matches the gap between the teeth of the drive gear 11 and can be inserted between the teeth to restrict the rotation of the drive gear 11 by physical blocking. This ensures that the drive gear 11 remains in a fixed position after adjustment, thereby ensuring the stability of the feeding track 4. The rod is inserted between the teeth of the drive gear 11. In the inserted state, the rod is tightly fitted with the teeth, which can effectively resist the rotation tendency of the drive gear 11 caused by vibration or external force, prevent the drive gear 11 from rotating on its own and causing the feeding track 4 to shift position, and provide a stable nut conveying channel for the plug-in loading process.

[0030] A sliding limit rod is fixed at the center of the other side wall of the gear limiting member 16. The sliding limit rod serves as a guide for the movement of the gear limiting member 16 and is slidably connected to the reset member protective shell 15. It restricts the movement direction of the gear limiting member 16, ensuring that the gear limiting member 16 always moves in a straight line under the pushing force of the reset member 18 or the pulling force of the limiting member pull plate 17, avoiding tilting or deviation. This ensures that the insertion rod can be inserted into or disengaged from the teeth of the drive gear 11. The sliding limit rod is slidably connected to the reset member protective shell 15. This sliding connection not only provides guidance for the gear limiting member 16 but also enhances the stability of the gear limiting member 16 during movement, reducing shaking and ensuring reliable limiting and releasing actions of the gear limiting member 16. A strip-shaped groove is provided in the side wall of the reset member protective shell 15. The strip-shaped groove provides a movement trajectory for the limiting member pull plate 17, and its length and width... The size of the limit plate 17 is matched with that of the limiting member pull plate 17, which can restrict the sliding of the limiting member pull plate 17 to only within the range of the strip groove, to avoid the limit member pull plate 17 from deviating when moving, and to ensure that the trajectory of the limit member pull plate 17 driving the gear limiting member 16 is fixed, thereby ensuring that the insertion rod can engage with the teeth of the drive gear 11. The sliding trajectory of the limiting member pull plate 17 is restricted by the strip groove. The fixed sliding trajectory makes it easier for the operator to pull the limiting member pull plate 17, and at the same time prevents the gear limiting member 16 from being damaged or unable to work properly due to the deviation of the limiting member pull plate 17, thus extending the service life of the component. A through hole is opened at the center of the end face of the reset member protective shell 15 to limit the sliding limiting rod. The through hole matches the size of the sliding limiting rod, which can guide and limit the movement of the sliding limiting rod, prevent the sliding limiting rod from radially shaking during the movement, and ensure that the gear limiting member 16 always moves in the correct direction.

[0031] When using this utility model: First, the base 1 of the vertical vibrator installed on the workbench provides stable support for the entire structure, ensuring that the vertical vibrator 2 and the components above it do not shake during operation. After the vertical vibrator 2 is started, it generates directional vibration. This vibration force drives the nuts in the upper feeding track 4 to move in a preset direction, realizing automatic nut feeding. During the process, the spring plates 3 on both sides of the vertical vibrator 2 buffer and adjust the vibration amplitude, reducing vibration transmission and noise. The feeding track 4 serves as the nut feeding channel. The steel plate 8 at the bottom of its interior reduces the friction when the nuts move. The steel plate fixing part 9 firmly fixes the steel plate 8 on the feeding track 4 to prevent the steel plate 8 from shifting or falling off, which would cause the nuts to jam. The pressure plate guide plates 5 at both ends of the feeding track 4 provide a sliding track for the guide plate support plate 6 through the bottom strip groove. The guide plate support plate 6 is fixed to the feeding track 4 by screws, and at the same time supports the nut pressure plate 7 at the top. The nut pressure plate 7 presses and limits the nuts in the feeding track 4 to prevent the nuts from popping out and to ensure that they are neatly arranged.

[0032] When the position of the nut pressure plate 7 needs to be adjusted to accommodate different specifications of nuts or plug-in loading requirements, operate the pressure plate adjustment assembly. First, pull the limit plate 17 on the side wall of the gear limit member 16. The limit plate 17 slides along the strip groove of the reset member protective shell 15, causing the gear limit member 16 to compress the reset member 18 inside the reset member protective shell 15. This causes the insert rod on the side of the gear limit member 16 away from the reset member 18 to disengage from the teeth of the drive gear 11, releasing the limit on the drive gear 11. Then, rotate the gear knob 12 outside the gear housing 10 to drive the drive gear 11 inside the gear housing 10 to rotate. The drive gear 11 meshes with the adjustment plate 13, converting the rotational motion into the linear motion of the adjustment plate 13. When the adjustment plate 13 moves, the top block 14 at the top of the adjustment plate 13 drives the nut pressure plate 7 to adjust its position. During the adjustment process, the teeth of the adjustment plate 13 ensure accurate transmission. The sliding limit rod on the other side wall of the gear limit member 16 slides along the through hole on the end face of the reset member protective shell 15 to ensure that the gear limit member 16 moves smoothly. After the adjustment is completed, the limit member pull plate 17 is released, the reset member 18 returns to its original state and pushes the gear limit member 16, so that the insertion rod is re-inserted between the teeth of the drive gear 11, fixing the position of the drive gear 11, and thus fixing the positions of the adjustment plate 13, the top block 14 and the nut pressure plate 7, ensuring that the feeding track 4 stably conveys the nut during the subsequent plug-in loading process, and completing the nut conveying and position adaptation work of the entire plug-in loading.
