Description

Technical Field

[0001] This invention belongs to the field of nut stamping and assembly technology, and more specifically, it relates to a stamping and assembly equipment for a washer-locking nut. Background Technology

[0002] Nut-and-washer stamping assembly equipment is an automated or semi-automated machine specifically designed to assemble washers onto nuts. Typically used in large-scale production environments, this equipment improves production efficiency, ensures consistent assembly quality, and reduces the need for manual operation. The design and functionality of nut-and-washer stamping assembly equipment may vary depending on specific application requirements and production scale. With the development of industrial automation technology, these machines may also integrate more intelligent and adaptive control functions to improve production efficiency and flexibility.

[0003] Currently, common nut-wasp stamping assembly equipment still has the following drawbacks:

[0004] 1. In some small factories, manual material loading is still performed. Operators need to repeat the loading action constantly, which increases labor intensity and fatigue. In today's era of increasingly developed automation technology, manual material loading is outdated and not conducive to the modernization of enterprises.

[0005] 2. In the stamping production process, if there is a lack of an effective waste collection mechanism, waste may be scattered in the work area, resulting in a messy working environment, affecting production efficiency, and requiring more manpower to clean up and handle the waste.

[0006] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a stamping and assembly equipment for inserting a locking nut, in order to achieve a more practical purpose. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a stamping and assembly device for inserting a locking nut, thereby resolving the problems described above.

[0008] A punching and assembly equipment for locking nuts with pads includes a frame and a worktable. A fixed block is provided above the frame. A collection box is provided on the upper surface of the worktable. A cylinder is fixedly installed on the lower surface of the worktable. A punching block is fixedly connected to the output shaft of the cylinder. A conveyor frame is provided inside the frame. A connecting plate is fixedly connected to the lower surface of the conveyor frame. Two motors are fixedly installed on the lower surface of the conveyor frame. A positioning block is provided on the right surface of the conveyor frame. Two sets of rollers are rotatably connected inside the conveyor frame. A cylinder is fixedly installed on the upper surface of the fixed block. A connecting block is fixedly connected to the output shaft of the cylinder. Two fixed shafts are fixedly connected to the upper surface of the frame. Gears are rotatably connected to both fixed shafts. Two connecting rods are movably engaged inside the frame. Two limiting grooves are provided on the inner wall of the frame. Limit blocks are fixedly connected to both limiting grooves. Arc-shaped blocks are fixedly connected to the opposite surfaces of the two connecting rods. Gears are fixedly connected to the connecting shafts of both sets of rollers. Two chains are respectively provided on the surface of the two sets of gears.

[0009] Preferably, the conveyor frame is provided with a nut body, and the two motor output shafts are respectively fixedly connected to the connecting shafts of the two rollers on the left side of the two sets of rollers. A circular groove is opened through the upper surface of the connecting plate, and the circular groove is movably sleeved with the first stamping block. A second stamping block is fixedly connected to the lower surface of the connecting block, and the second stamping block is movably sleeved with the fixed block.

[0010] Preferably, the inner wall of the frame has two slot 1 and two slot 2 extending through it. The left and right sides of the collection box are fixedly connected with locking blocks. The two locking blocks are respectively movably engaged with the two slot 1. The lower surface of the connecting block is fixedly connected with two fixing rods 1. The two fixing rods 1 are respectively movably engaged with two gears 2. The opposite surfaces of the two connecting rods are each provided with a limiting groove 2. The two limiting grooves 2 are each movably engaged with a limiting block 2.

[0011] Preferably, springs are fixedly connected to the back sides of both limiting blocks, and the two springs are fixedly connected to the two limiting grooves respectively. The two limiting blocks are connected to the two limiting blocks through inclined surfaces. Limiting grooves are opened on the opposite surfaces of the two arc-shaped blocks, and the two limiting grooves are movably engaged with the two limiting blocks respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the nut body is moved together by the rotation of two sets of rollers, thus completing the feeding process. The nut body is positioned by the positioning block on the right side of the conveyor frame, so that the flat surface of the nut body fits with the two sets of rollers. Two limit strips are set in the conveyor frame to ensure the stability of the nut body during the feeding process. The overall operation is simple, and the automated feeding ensures the consistency of operation and improves production efficiency.

[0014] In this invention, the two gears 1 that are engaged with each other by the two gears 2 during rotation will be subjected to pressure and move upward. As the two connecting rods move upward, they will drive the arc-shaped blocks fixed to them to move. At this time, the shims placed inside the two arc-shaped blocks will also move upward to fit against the stamping block 2. This structure effectively ensures that the position of the shims is fixed during the stamping process, and will not easily move or misalign, thus ensuring the quality of stamping.

[0015] In this invention, two motors drive the stamped nut body to move, enabling uninterrupted automated processing, significantly improving production efficiency and reducing production cycle. Meanwhile, the waste generated during stamping of the gasket falls into the collection box below along with the stamped block for collection. Waste collection helps maintain the cleanliness of the work area, improves the overall quality of the working environment, and facilitates the classification and recycling of the collected waste, meeting environmental protection requirements and reducing resource waste.

[0024] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0025] Please see Figure 1 - Figure 7 This invention provides a punching and assembly equipment for locking nuts with through-wafers, including a frame 1 and a worktable 2. A fixing block 7 is provided above the frame 1. A collection box 4 is provided on the upper surface of the worktable 2. A cylinder 3 is fixedly installed on the lower surface of the worktable 2. The output shaft of the cylinder 3 is fixedly connected to a punching block 13. A conveyor frame 5 is provided inside the frame 1. A connecting plate 8 is fixedly connected to the lower surface of the conveyor frame 5. Two motors 9 are fixedly installed on the lower surface of the conveyor frame 5. A positioning block 11 is provided on the right surface of the conveyor frame 5. Two sets of rollers 1 are rotatably connected inside the conveyor frame 5. 4. A cylinder 6 is fixedly mounted on the upper surface of the fixed block 7. A connecting block 18 is fixedly connected to the output shaft of the cylinder 6. Two fixed shafts 20 are fixedly connected to the upper surface of the frame 1. Gears 19 are rotatably connected inside both fixed shafts 20. Two connecting rods 26 are movably engaged inside the frame 1. Two limiting grooves 23 are opened on the inner wall of the frame 1. Limiting blocks 24 are fixedly connected inside both limiting grooves 23. Arc-shaped blocks 31 are fixedly connected to the opposite faces of the two connecting rods 26. Gears 16 are fixedly connected to the connecting shafts of the two sets of rollers 14. Two sets of gears 16 each have two chains 17 on their surfaces. When the nut body 12 and the washer are stamped, the two motors 9 are first started, and their output shafts drive the rollers 14 fixed to them to rotate. When the two rollers 14 rotate, the gears 16 fixed to them drive the chains 17 to rotate. During the rotation of the two chains 17 under force, they drive the other engaged rollers 14 to rotate together. At this time, the two sets of rollers 14 are in a state of relative rotation. Both sets of rollers 14 are rotatably set in the conveyor frame 5. All rollers 14 are made of rubber. The nut body 12 to be stamped is placed in the two sets of rollers 14. The rotation of the two sets of rollers 14 will push it to move together, thus completing the feeding process. The position of the nut body 12 is aligned by the positioning block 11 on the right side of the conveyor frame 5, so that the flat surface of the nut body 12 is in contact with the two sets of rollers 14. Two limit strips are set in the conveyor frame 5 to ensure the stability of the nut body 12 during the feeding process. The overall operation is simple, and the automated feeding ensures the consistency of operation and improves production efficiency.

[0026] The conveyor frame 5 contains a nut body 12. The output shafts of two motors 9 are fixedly connected to the connecting shafts of the two rollers 14 located on the left side of the two sets of rollers 14, respectively. A circular groove 15 is formed through the upper surface of the connecting plate 8. The circular groove 15 is movably sleeved with the first stamping block 13. A second stamping block 35 is fixedly connected to the lower surface of the connecting block 18. The second stamping block 35 is movably sleeved with the fixed block 7. When the nut body 12 moves below the second stamping block 35, the two motors 9 will stop rotating. The shim is placed between the two arc-shaped blocks 31 and limited by the second limiting block 30 set in the arc-shaped block 31. The output shaft of the second cylinder 6 will drive the connecting block 18 fixed to it to move downward. During the movement of the connecting block 18, the stamping block 35 and the two fixed rods 27 fixed to it will move together. During the movement of the two fixed rods 27, the two gears 19 engaged with them will rotate. During the rotation of the two gears 19, the two connecting rods 26 will be subjected to pressure and move upward. During the upward movement of the two connecting rods 26, the arc-shaped block 31 fixed to it will move. At this time, the shims placed in the two arc-shaped blocks 31 will also move upward to fit against the stamping block 35. This structure effectively ensures that the position of the shims is fixed during the stamping process, and will not easily move or misalign, thus ensuring the quality of stamping.

[0027] The inner wall of the frame 1 has two slots 21 and two slots 25 extending through it. The left and right sides of the collection box 4 are fixedly connected to locking blocks 22, which are respectively engaged with the two slots 21. The lower surface of the connecting block 18 is fixedly connected to two fixing rods 27, which are respectively engaged with two gears 19. The opposite surfaces of the two connecting rods 26 each have a limiting groove 32, and each limiting groove 32 has a limiting block 30 that is engaged with it. When the cylinder 3 is activated, its output shaft drives the fixed stamping block 13 to move upwards. During this movement, the stamping block 13 passes through the circular groove 15 on the connecting plate 8 and comes into contact with the upper nut body 12. This contact and contact propels it to continue moving upwards. At this time, the nut body 12, during its upward movement, will contact the pad... The nut body 12 is embedded in the washer during the stamping process, and the two connecting rods 26 drive the washer to rise. During the rising process, the two limiting blocks 1 24 fixed inside the frame 1 will engage with the limiting blocks 2 30 set inside the two connecting rods 26. The upper surface of the two limiting blocks 2 30 is provided with inclined grooves, and the two limiting blocks 1 24 are both inclined. During the rising process, the two limiting blocks 1 24 will push the two limiting blocks 2 30 to move towards the opposite side due to the inclined design, compressing the two springs 29, opening the limit, and the washer can move up and down as a whole. After the stamping is completed, it is reset by the stamping block 1 13. The two motors 9 start to push the stamped nut body 12 to move. The whole automated processing can be operated without interruption, which significantly improves production efficiency and reduces the production cycle.

[0028] Two limit blocks 30 are fixedly connected to springs 29 on their back sides. The two springs 29 are fixedly connected to two limit grooves 32 respectively. The two limit blocks 30 are connected to the two limit blocks 24 by inclined surfaces. The two arc blocks 31 have limit grooves 33 on their opposite sides. The two limit grooves 33 are movably engaged with the two limit blocks 30 respectively. The waste generated by the stamping in the middle of the gasket will fall into the collection box 4 below with the stamping block 13 for collection. Waste collection helps to keep the work area clean and improve the overall quality of the work environment. The centrally collected waste is easy to classify and recycle, which meets environmental protection requirements and reduces resource waste.

[0029] Working principle:

[0030] In the first step, when stamping the nut body 12 and the washer, the output shafts of the two motors 9 are started, which drive the rollers 14 fixed to them to rotate. When the two rollers 14 rotate, the gears 16 fixed on them drive the chains 17 to rotate. When the two chains 17 rotate under force, they drive the other engaged rollers 14 to rotate together. At this time, the two sets of rollers 14 are in a relative rotation state. Both sets of rollers 14 are rotatably set in the conveyor frame 5. Both sets of rollers 14 are made of rubber. The nut body 12 to be stamped is placed in the two sets of rollers 14. The rotation of the two sets of rollers 14 will push it to move together. At this time, the feeding process is completed. The position of the nut body 12 is straightened by the positioning block 11 on the right side of the conveyor frame 5 so that the flat surface of the nut body 12 is in contact with the two sets of rollers 14. Two limit strips are set in the conveyor frame 5 to ensure the stability of the nut body 12 during the feeding process. The overall operation is simple, and the automated feeding ensures the consistency of operation and improves production efficiency.

[0031] In the second step, when the nut body 12 moves below the second stamping block 35, the two motors 9 will stop rotating and place the shim between the two arc-shaped blocks 31. The shim is limited by the second limiting block 30 set inside the arc-shaped block 31. The output shaft of the second cylinder 6 will drive the connecting block 18 fixed to it to move downward. During the movement of the connecting block 18, it will drive the second stamping block 35 fixed to it and the two fixing rods 27 to move together. During the movement of the two fixing rods 27, it will drive the two gears 19 engaged with it to rotate. During the rotation of the two gears 19, the two connecting rods 26 will be pressured and move upward. During the upward movement of the two connecting rods 26, it will drive the arc-shaped blocks 31 fixed to it to move. At this time, the shim placed inside the two arc-shaped blocks 31 will also move upward to fit against the second stamping block 35. This structure effectively ensures that the position of the shim is fixed during the stamping process and will not easily move or misalign, thus ensuring the quality of the stamping.

[0032] Thirdly, cylinder 3 starts, and its output shaft drives the fixed stamping block 13 to move upward together. During the movement, the stamping block 13 passes through the circular groove 15 on the connecting plate 8 and comes into contact with the nut body 12 above. The contact and push push it to continue moving upward. At this time, the nut body 12 will contact the washer and be stamped during the upward movement. The nut body 12 is embedded in the washer. During the upward movement of the two connecting rods 26, the two limiting blocks 24 fixed in the frame 1 will engage with the limiting blocks 30 set in the two connecting rods 26. The upper surface of the two limiting blocks 30 is provided with inclined grooves, and the two limiting blocks 24 are both designed to be inclined. During the upward movement, the two limiting blocks 24 engage with the limiting blocks 30 set in the two connecting rods 26. The upper surface of the two limiting blocks 30 is provided with inclined grooves, and the two limiting blocks 24 are both designed to be inclined. The inclined design of position block 24 pushes the two limit blocks 30 to move towards the opposite side, compressing the two springs 29 and opening the limit. The entire gasket can move up and down. After the stamping is completed, it is reset by stamping block 13. The two motors 9 start to push the stamped nut body 12 to move. The overall automated processing can be carried out without interruption, which significantly improves production efficiency and reduces the production cycle. The waste generated in the middle of the gasket will fall into the collection box 4 below with stamping block 13 for collection. Waste collection helps to keep the work area clean and improve the overall quality of the working environment. The centrally collected waste is easy to classify and recycle, which meets environmental protection requirements and reduces resource waste.
