Description

Technical Field

[0001] This utility model relates to the field of fastener processing equipment technology, specifically a locking nut production and processing device. Background Technology

[0002] Lock nuts are nuts with anti-loosening function. Through special structural design, they can prevent loosening between the nut and bolt under conditions such as vibration and impact, ensuring the reliability and stability of the connection. Lock nuts are widely used in many fields such as machinery and construction, and their quality and processing efficiency directly affect the development of related industries.

[0003] However, existing lock nut production and processing equipment still has certain problems in use:

[0004] For example, a locking nut processing device with application number CN201920595989.3 facilitates the support and fixation of nuts while also facilitating the tilting of nuts; it includes a worktable; and also includes a front support leg, a rear support leg, a front rotating block, a rear rotating block, a right rotating block, a fixed block, a base plate, a hydraulic cylinder, a left threaded rod, a right threaded rod, a left rotating shaft, a right rotating shaft, a turntable, a handle, a left moving plate, a right moving plate, a front fixed rod, a rear fixed rod, a first rod, a second rod, a third rod, and a fourth rod. The worktable has a working cavity inside, and the top side wall of the worktable is connected to a front moving port and a rear moving port. The bottom ends of the first rod and the second rod pass through the front moving port and the rear moving port respectively and are connected to the front half area and the rear half area of ​​the top side wall of the left moving plate respectively. The left side wall and the right side wall of the worktable are connected to a left placement port and a right placement port respectively, and two sets of ball bearings are respectively provided at the left placement port and the right placement port.

[0005] Traditional locking nut processing equipment is mostly single-station operation, which can only process one nut at a time, and cannot meet the needs of mass production.

[0006] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0007] To address the aforementioned issues, an innovative design was implemented based on the existing lock nut production and processing equipment. Utility Model Content

[0008] The purpose of this utility model is to provide a locking nut production and processing device to solve the problem that the locking nut processing equipment mentioned in the background art is mostly single-station operation, and a single-station operation can only process one nut at a time, which cannot meet the needs of mass production.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A locking nut manufacturing and processing device includes a base and a housing: the housing is welded to the upper end face of the base, a rotating disk is movably connected to the middle of the housing, a second motor is installed inside the base, a drive shaft is fixed to the output end of the second motor, a sector gear is fixed to the outer surface of the drive shaft, a bearing seat is installed in the middle of the base, a transmission shaft is fixed to the inner ring of the bearing seat, a driven gear is fixed to the outer surface of the transmission shaft, and the top end of the transmission shaft is fixedly connected to the bottom of the rotating disk, with the sector gear meshing with the driven gear; a support seat is fixed to the outer surface of the rotating disk, a second electric push rod is installed inside the support seat, and a clamp is fixed to the output end of the second electric push rod.

[0011] By adopting the above technical solution, the second motor in the base drives the drive shaft to rotate the sector gear. The intermittent meshing of the sector gear and the driven gear drives the transmission shaft and the rotating disk to rotate in steps to achieve multi-station switching. The second electric push rod in the support seat on the rotating disk drives the clamp to slide. The structure at the top of the clamp realizes automatic centering and clamping of the nut. This not only ensures the accurate positioning of the rotating disk during processing at each station, but also improves production efficiency through automated clamping and station switching. At the same time, it reduces manual intervention and meets the needs of mass production and high precision of locking nuts.

[0012] Preferably, the support bases are evenly distributed in four groups along the outer surface of the rotating disk, and each group has two support bases, with the second electric push rod and clamp corresponding to the support bases.

[0013] Using the above technical solution, the support seats are symmetrically distributed in four groups along the outer surface of the rotating disk, with two seats in each group. The uniform layout forms a multi-station clamping structure. The second electric push rod in each support seat drives the corresponding clamp to slide along a fixed path. The mechanical linkage enables the clamp to clamp or release the nuts synchronously. Multiple nuts can be clamped at the same time and transferred to the processing position in steps, improving equipment utilization. The double clamp structure enhances clamping stability and, together with the rotation of the workstations, enables continuous production, meeting the requirements of high capacity and consistent quality.

[0014] Preferably, the top of the clamp has a V-shaped structure, and the clamp and the support are slidably connected.

[0015] By adopting the above technical solution, the top of the clamp is designed as a V-shaped structure, and the automatic centering characteristic of the V-groove is used to realize the rapid positioning and clamping of the nut. At the same time, the clamp and the support are slidably connected, and the electric push rod drives the smooth clamping and release, ensuring the stability of the locking nut processing and improving the processing accuracy.

[0016] Preferably, a fixed seat is welded to the upper end face of the rotating disk, a third electric push rod is fixed to one side of the fixed seat, a push plate is fixed to the output end of the third electric push rod, and the push plate is positioned between two sets of clamps, and four sets of push plates and support seats are arranged correspondingly.

[0017] Using the above technical solution, the third electric push rod on one side of the fixed seat drives the push plate at the output end to move horizontally through the controller command. Since the push plate is set between the two sets of clamps and corresponding to the four sets of support seats, after the nut is processed at the corresponding station of the rotating disk, the push plate can accurately extend into the gap of the clamps to realize the automated ejection of the processed nut, replacing manual operation, improving the output efficiency and production continuity, while avoiding surface damage to the nut that may be caused by manual contact, and ensuring product quality.

[0018] Preferably, a controller is installed on one side of the base, an L-shaped fixing bracket is fixed on one side of the base, a first electric push rod is fixed at the top of the fixing bracket, and a mounting base is fixed at the output end of the first electric push rod.

[0019] Using the above technical solution, the controller outputs control commands through a preset program or real-time signal to drive the first electric push rod at the top of the L-shaped fixed frame to extend and retract according to a set stroke, thereby driving the fixed mounting base at the output end to achieve precise vertical displacement, forming an automated mechanical transmission link. This structure links electrical control with mechanical execution, realizing automated feeding and retraction of processing modules (such as tapping heads), reducing human operation errors.

[0020] Preferably, a first motor is installed inside the mounting base, and a tapping head is fixed to the output end of the first motor.

[0021] By adopting the above technical solution, the tapping head is driven to rotate by the first motor inside the mounting base, and the lifting and lowering motion of the first electric push rod is coordinated to realize the automatic tapping of the nut thread hole.

[0022] Preferably, a discharge slide is fixed on one side of the base, and one end of the discharge slide is perpendicular to the pusher plate, and the surface of the discharge slide has a smooth structure.

[0023] Using the above technical solution, the discharge chute is fixed at a position perpendicular to the pusher plate. The pusher plate pushes the processed nuts to the chute inlet. The smooth surface of the chute reduces frictional resistance, allowing the nuts to slide automatically down the chute under gravity. This achieves automated nut discharge and collection, avoids manual intervention, and improves production continuity. At the same time, the smooth structure reduces surface damage to the nuts, ensures product quality, and reduces subsequent processing costs.

[0024] Compared with the prior art, the beneficial effects of this utility model are: this locking nut production and processing device,

[0025] 1. The intermittent meshing of the sector gear and the driven gear drives the rotating disk to rotate in steps, realizing automatic switching between multiple workstations and significantly improving processing efficiency. At the same time, the discontinuous meshing characteristics of the sector gear ensure that the rotating disk is accurately positioned at the processing position, avoiding processing errors caused by vibration or offset, ensuring the accuracy and consistency of nut threads, and meeting the quality stability requirements of mass production.

[0026] 2. The evenly distributed V-shaped clamps on the rotating disk are driven by electric push rods to automatically center and clamp the nuts, simplifying the clamping process and improving positioning accuracy. Combined with the collaborative design of the pusher plate and smooth discharge slide, the processed nuts can quickly slide to the collection area, reducing manual intervention and further shortening the production cycle. The automated collaboration of each module significantly reduces operational complexity, improves production continuity, and meets the demand for efficient and low-cost nut production.

[0027] 3. Through controller commands, the third electric push rod on one side of the fixed seat drives the push plate at the output end to move horizontally. Since the push plate is set between the two sets of clamps and the four sets of support seats, after the nut is processed at the corresponding station of the rotating disk, the push plate can accurately extend into the gap of the clamps to realize the automatic ejection of the processed nut, replace manual operation, improve the output efficiency and production continuity, and at the same time avoid the surface damage of the nut that may be caused by manual contact, thus ensuring product quality.

[0028] 4. The discharge chute is fixed vertically to the position of the pusher plate. The pusher plate pushes the processed nuts to the chute inlet. The smooth surface of the chute reduces frictional resistance, allowing the nuts to slide down automatically along the chute under gravity. This achieves automated nut discharge and collection, avoiding manual intervention and improving production continuity. At the same time, the smooth structure reduces surface damage to the nuts, ensuring product quality and reducing subsequent processing costs. Attached Figure Description

[0037] A locking nut manufacturing and processing device includes a base 1 and a housing 8. The housing 8 is welded to the upper end face of the base 1. A rotating disk 9 is movably connected to the middle of the housing 8. A second motor 10 is installed inside the base 1. A drive shaft 11 is fixed to the output end of the second motor 10. A sector gear 12 is fixed to the outer surface of the drive shaft 11. A bearing seat 13 is installed in the middle of the base 1. A transmission shaft 14 is fixed to the inner ring of the bearing seat 13. A driven gear 15 is fixed to the outer surface of the transmission shaft 14. The top end of the transmission shaft 14 is fixedly connected to the bottom of the rotating disk 9. The sector gear 12 and the driven gear 15 are meshed together.

[0038] This locking nut production and processing device uses a second motor 10 inside the base 1 to drive the drive shaft 11 to rotate the sector gear 12. Utilizing the intermittent meshing characteristics of the sector gear 12 and the driven gear 15, the device drives the transmission shaft 14 fixed inside the bearing housing 13 and the rotating disk 9 to rotate in steps, achieving automatic switching and precise positioning of multiple workstations. The non-continuous meshing cycle of the sector gear 12 ensures that the rotating disk 9 remains stationary when it stops at the processing position, avoiding vibration from affecting processing accuracy. At the same time, the intermittent pauses provide independent processing time for each workstation, ultimately realizing automated production of nuts through multiple processes, improving processing efficiency and product consistency.

Four sets of support bases 16 are evenly distributed along the outer surface of the rotating disk 9, with two support bases 16 in each set. The second electric push rod 17 and the clamp 18 correspond to the support bases 16. The top of the clamp 18 has a V-shaped structure, and the clamp 18 and the support base 16 are slidably connected.

Four sets of push plates 21 are correspondingly arranged with the support bases 16. A discharge slide 22 is fixed to one side of the base 1, and one end of the discharge slide 22 is perpendicular to the push plate 21. The surface of the discharge slide 22 has a smooth structure.

[0042] This locking nut production and processing device has four sets of support seats 16 evenly distributed on the outer surface of the rotating disk 9, with two seats in each set. The second electric push rod 17 inside the support seat 16 drives the clamping seat 18 to slide along the support seat 16. The V-shaped structure at the top of the clamping seat 18 realizes automatic centering and clamping of the nut. The third electric push rod 20 on one side of the fixed seat 19 on the upper end face of the rotating disk 9 drives the push plate 21 to move horizontally. The push plate 21 corresponds between the two sets of clamping seats 18 and is set in correspondence with the four sets of support seats 16. After the nut is processed, the push plate 21 pushes the nut out of the clamping seat 18 to the vertically corresponding discharge slide 22. The smooth surface of the discharge slide 22 realizes the automatic sliding and collection of the nut. The coordinated operation of each module realizes the automated clamping, processing and discharge of the nut, improving production efficiency.

A first motor 6 is installed inside the mounting base 5, and a tapping head 7 is fixed at the output end of the first motor 6.

[0046] In this locking nut production and processing device, the controller 2 on one side of the base 1 is responsible for parameter setting and process control. The L-shaped fixing frame 3 supports the first electric push rod 4 to drive the mounting base 5 to rise and fall vertically. The first motor 6 inside the mounting base 5 drives the tapping head 7 to rotate at high speed. Through the coordinated action of the displacement of the electric push rod and the rotation of the motor, the tapping head 7 can accurately tap the nuts at the corresponding work positions on the rotating disk 9. The controller 2 can adjust the push rod stroke and the motor speed to adapt to nuts of different specifications, ensuring thread accuracy and production efficiency.

The nuts at each station arrive at the processing position in sequence. The controller 2 on one side of the base 1 controls the first electric push rod 4 on the L-shaped fixing frame 3 to drive the mounting seat 5 to rise and fall. The first motor 6 inside the mounting seat 5 drives the tapping head 7 to rotate, completing the tapping processing of the nut at the current station.
