Description

Technical Field

[0001] This invention belongs to the field of stainless steel nut assembly processing technology, and particularly relates to a pressure-receiving device for processing stainless steel nut assemblies. Background Technology

[0002] The pressure-receiving device for stainless steel nut assembly processing is a specialized piece of equipment used in the processing of stainless steel nut assemblies for processes such as closing and pressing. Its core function is to apply precise pressure to cause the components of the nut assembly to undergo a pre-set deformation or secure assembly, solving problems such as unstable quality and high strength in manual operation, and ensuring the dimensional accuracy and connection reliability of the components. It is commonly used in the processing of various stainless steel nut assemblies such as plate nuts and pipe fitting nuts.

[0003] The worktable height of traditional stainless steel nut assembly processing pressing devices is mostly fixed, and cannot be flexibly adjusted according to the operator's height and working habits. Long-term use will cause significant chronic damage to the operator's lumbar health.

[0004] When the workbench height is too high, operators need to continuously raise their arms and bend forward to perform tasks such as loading, positioning, and operation control. The muscles on the back of the waist are constantly under passive tension, and repeated stretching of muscle fibers can easily lead to fatigue injury. Long-term accumulation can lead to lumbar muscle strain, manifested as persistent soreness in the lower back and limited mobility. When the workbench height is too low, operators need to bend over and lean close to the workbench to work. At this time, the physiological curvature of the lumbar spine is forced to change, and the longitudinal pressure on the intervertebral discs increases significantly. The annulus fibrosus of the intervertebral disc is under high pressure for a long time, which can easily lead to wear and rupture, thereby inducing lumbar disc herniation. It may also accelerate the process of lumbar degenerative disease, accompanied by symptoms such as radiating pain in the lower back and numbness in the lower limbs, which seriously affects the operator's health and long-term working ability. In view of this, we propose a pressure-reducing device for processing stainless steel nut assemblies. Summary of the Invention

[0005] The purpose of this invention is to provide a pressure-reducing device for processing stainless steel nut assemblies, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a pressing device for processing stainless steel nut assemblies, comprising a worktable and several trays, and further comprising: Several metal gaskets are fixedly connected to one end of several trays respectively; Two fixed plates are fixedly connected to both sides of the workbench. The bottom surface of each fixed plate is provided with a sliding groove. A support plate is slidably connected in each of the two sliding grooves. Two lead screws are threadedly connected in each of the two support plates. Two movable slots are respectively opened in two fixed plates and are respectively connected to two sliding grooves. Two synchronous pulleys are rotatably connected in each of the two movable slots. The bottom ends of several synchronous pulleys extend into the two sliding grooves and are respectively fixedly connected to the top ends of several lead screws. Two synchronous belts mesh between the several synchronous pulleys. A rotating assembly, located between two fixed plates, is used to drive two of the synchronous pulleys to rotate.

[0007] This technical solution can prevent several support plates from damaging the nuts and ensure that the user can adjust the height of the workbench according to the operator's working comfort.

[0008] In the above technical solution, the rotating component further includes: Two first gear slots are respectively opened in two fixed plates and are respectively connected to two movable slots. A first bevel gear and a second bevel gear are rotatably connected in each of the two first gear slots, and the first bevel gear and the second bevel gear mesh with each other. One end of each of the two first bevel gears extends into the two movable slots and is respectively fixedly connected to two of the synchronous pulleys. A first rotating slot is opened on the inner wall of each of the two first gear slots. A connecting plate is fixedly connected between two fixed plates. The connecting plate has two second gear slots, which are respectively connected to two first rotating slots. A third bevel gear and a fourth bevel gear are rotatably connected in each of the two second gear slots, and the third bevel gear and the fourth bevel gear mesh with each other. One end of each of the two third bevel gears is fixedly connected to a first connecting rod, and one end of each of the two first connecting rods passes through the two first rotating slots and extends into the two first gear slots to be fixedly connected to the two second bevel gears. The second rotating groove is formed inside the connecting plate and communicates with the two second gear grooves. A second connecting rod is rotatably connected inside the second rotating groove, and the two ends of the second connecting rod extend into the two second gear grooves and are fixedly connected to the two fourth bevel gears respectively. A servo motor is fixedly connected to one end of a connecting plate, and the output shaft of the servo motor extends into one of the second gear slots and is fixedly connected to one end of a second connecting rod.

[0009] In this technical solution, it is ensured that the user can drive two of the synchronous pulleys to rotate simultaneously.

[0010] In the above technical solution, the bottom end of the first bevel gear is rotatably connected to the movable groove, and the first connecting rod is rotatably connected to the first rotating groove and the first gear groove.

[0011] In this technical solution, it is ensured that when the first bevel gear rotates, the bottom end of the first bevel gear can rotate normally in the movable groove, and it is also ensured that when the first connecting rod rotates, the first connecting rod can rotate normally in the first rotating groove and the first gear groove.

[0012] In the above technical solution, further, the two ends of the second connecting rod are rotatably connected to two second gear slots respectively, and the output shaft of the servo motor is rotatably connected to one of the second gear slots.

[0013] In this technical solution, it is ensured that when the second connecting rod rotates, both ends of the second connecting rod can rotate normally in the two second gear slots respectively, and it is also ensured that when the servo motor is started, the output shaft of the servo motor can rotate normally in one of the second gear slots.

[0014] Furthermore, the above technical solution also includes: Two limiting grooves are respectively opened on the inner wall of two movable grooves. Tensioning wheels are slidably connected in both limiting grooves, and the two tensioning wheels are respectively in contact with two synchronous belts. Two electric telescopic rods are fixedly connected to two fixed plates, and the output shafts of the two electric telescopic rods pass through the two fixed plates and extend into the two limiting grooves and are fixedly connected to the two tensioning wheels.

[0015] In this technical solution, users can control the tension of the timing belt to prevent it from loosening during long-term use.

[0016] In the above technical solution, the tensioning wheel is slidably connected to the movable groove, and the output shaft of the electric telescopic rod is slidably connected to the limiting groove.

[0017] In this technical solution, it is ensured that when the tensioning wheel slides, the tensioning wheel can slide normally within the movable groove, and it is also ensured that when the electric telescopic rod is started, the output shaft of the electric telescopic rod can slide normally within the limit groove.

[0018] In the above technical solution, further, the two lead screws are located in the slide groove and are rotatably connected to the slide groove, and the threads on the plurality of lead screws have the same direction of rotation and the same thread pitch.

[0019] In this technical solution, it is ensured that when the two lead screws rotate, the two lead screws can rotate normally in the slide groove. Furthermore, because the threads on several lead screws have the same direction of rotation and the same thread pitch, when several lead screws rotate, the two support plates will be moved downward simultaneously by the action of several lead screw threads.

[0020] In the above technical solution, further, the bottom ends of the two synchronous pulleys are rotatably connected to the slide groove, the synchronous belt is in contact with the inner wall of the movable groove, and the metal gasket is a smooth stainless steel sheet with a thickness of 0.3mm.

[0021] In this technical solution, it is ensured that when the two synchronous pulleys rotate, the bottom ends of the two synchronous pulleys can rotate normally within the slide groove. Furthermore, because the synchronous belt is in contact with the inner wall of the movable groove, when the synchronous belt is transmitted between the two synchronous pulleys, it will be restricted by the inner wall of the movable groove, preventing the problem of tooth stripping. At the same time, because the metal shims are smooth stainless steel sheets with a thickness of 0.3mm, several metal shims can provide protection for the nut, preventing several support plates from damaging the nut.

[0022] The beneficial effects of this invention are: 1. This stainless steel nut assembly processing pressure device, through the setting of metal shims, prevents damage to the nut when several support plates are squeezed, effectively improving the product appearance and avoiding performance reduction due to indentation. Through the setting of synchronous pulleys, a first gear groove, a first bevel gear, a second bevel gear, a first rotating groove, a connecting plate, a second gear groove, a third bevel gear, a fourth bevel gear, a first connecting rod, a second rotating groove, a second connecting rod, and a servo motor, two of the synchronous pulleys can rotate simultaneously. Through the setting of sliding grooves, support plates, lead screws, movable grooves, synchronous pulleys, and synchronous belts, the worktable can be raised and lowered. The design of the above structure allows the operator to flexibly adjust the worktable to the optimal operating height according to work comfort, maintaining a natural and relaxed working posture and reducing the impact on the operator's health.

[0023] 2. The pressure-retracting device for processing the stainless steel nut assembly, through the setting of a limiting groove, a tensioning wheel, and an electric telescopic rod, allows the user to control the movement of the tensioning wheel. The design of the above structure allows the tensioning wheel to compress the timing belt, control the tension of the timing belt, and thus improve the stability of the overall device during long-term use.

Detailed Implementation The following is in conjunction with the appendix Figure 1 - Figure 9 This application will be described in further detail.

[0026] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0027] Example 1: This example provides a pressing device for processing stainless steel nut assemblies, including a worktable 1 and several support plates 24, and further including: Several metal washers 25 are fixedly connected to one end of several trays 24 respectively; Two fixed plates 2 are fixedly connected to both sides of the workbench 1. The bottom surface of each fixed plate 2 is provided with a sliding groove 3. A support plate 4 is slidably connected in each of the two sliding grooves 3. Two lead screws 5 are threadedly connected in each of the two support plates 4. Two movable slots 6 are respectively opened in two fixed plates 2 and are respectively connected to two sliding grooves 3. Two synchronous pulleys 7 are rotatably connected in each of the two movable slots 6, and the bottom ends of several synchronous pulleys 7 extend into the two sliding grooves 3 and are respectively fixedly connected to the top ends of several lead screws 5. Two synchronous belts 8 are respectively engaged between the several synchronous pulleys 7. A rotating assembly is located between two fixed plates 2 and is used to drive two of the synchronous pulleys 7 to rotate.

[0028] In use, when several support plates 24 press against the nut, several metal washers 25 will protect the nut and prevent the several support plates 24 from damaging the nut. In use, the user rotates the assembly to drive two of the synchronous pulleys 7 to rotate within the two movable slots 6. These two synchronous pulleys 7 then drive the other two synchronous pulleys 7 to rotate via two synchronous belts 8, causing several synchronous pulleys 7 to rotate simultaneously. As these synchronous pulleys 7 rotate, they drive several lead screws 5 to rotate within the two support plates 4. This causes the two support plates 4 to move downwards simultaneously under the action of the screw threads of the lead screws 5, which in turn causes the two fixed plates 2 to move the worktable 1 upwards relative to each other. This allows the user to adjust the height of the worktable 1 according to the operator's comfort level.

[0029] Example 2: This example provides a pressure-receiving device for processing stainless steel nut assemblies. In addition to the technical solutions described in the above examples, it also has the following technical features: the rotating component includes: Two first gear slots 9 are respectively opened in two fixed plates 2 and are respectively connected to two movable slots 6. A first bevel gear 10 and a second bevel gear 11 are rotatably connected in each of the two first gear slots 9, and the first bevel gear 10 and the second bevel gear 11 mesh with each other. One end of each of the two first bevel gears 10 extends into the two movable slots 6 and is respectively fixedly connected to two of the synchronous pulleys 7. A first rotating slot 12 is opened on the inner wall of each of the two first gear slots 9. A connecting plate 13 is fixedly connected between two fixed plates 2. Two second gear slots 14 are opened in the connecting plate 13, and the two second gear slots 14 are respectively connected to two first rotating slots 12. A third bevel gear 15 and a fourth bevel gear 16 are rotatably connected in each of the two second gear slots 14, and the third bevel gear 15 and the fourth bevel gear 16 mesh with each other. One end of each of the two third bevel gears 15 is fixedly connected to a first connecting rod 17, and one end of each of the two first connecting rods 17 passes through the two first rotating slots 12 and extends into the two first gear slots 9 to be fixedly connected to the two second bevel gears 11. The second rotating groove 18 is opened in the connecting plate 13 and communicates with the two second gear grooves 14. The second rotating groove 18 is rotatably connected to the second connecting rod 19, and the two ends of the second connecting rod 19 extend into the two second gear grooves 14 and are fixedly connected to the two fourth bevel gears 16 respectively. The servo motor 20 is fixedly connected to one end of the connecting plate 13, and the output shaft of the servo motor 20 extends into one of the second gear slots 14 and is fixedly connected to one end of the second connecting rod 19.

[0030] The user starts the servo motor 20, causing its output shaft to drive the second connecting rod 19 to rotate within the second rotating groove 18. This causes the second connecting rod 19 to drive two fourth bevel gears 16 to rotate within the two second gear grooves 14. The two fourth bevel gears 16 then drive two third bevel gears 15 to rotate within the two second gear grooves 14. When the two third bevel gears 15 rotate, they will drive two second bevel gears 11 to rotate within the two first gear grooves 9 via the two first connecting rods 17. The two second bevel gears 11 will then drive two first bevel gears 10 to rotate, which in turn will drive two synchronous pulleys 7 to rotate within the two movable grooves 6, ensuring that the user can drive two synchronous pulleys 7 to rotate simultaneously.

[0031] Example 3: This example provides a pressing device for processing stainless steel nut assemblies. In addition to the technical solutions of the above examples, it also has the following technical features: the bottom end of the first bevel gear 10 is rotatably connected to the movable groove 6, and the first connecting rod 17 is rotatably connected to the first rotating groove 12 and the first gear groove 9.

[0032] Specifically, it is ensured that when the first bevel gear 10 rotates, the bottom end of the first bevel gear 10 can rotate normally within the movable groove 6, and that when the first connecting rod 17 rotates, the first connecting rod 17 can rotate normally within the first rotating groove 12 and the first gear groove 9.

[0033] Example 4: This example provides a pressing device for processing stainless steel nut assemblies. In addition to the technical solutions of the above examples, it also has the following technical features: the two ends of the second connecting rod 19 are rotatably connected to two second gear slots 14 respectively, and the output shaft of the servo motor 20 is rotatably connected to one of the second gear slots 14.

[0034] Specifically, it is ensured that when the second connecting rod 19 rotates, both ends of the second connecting rod 19 can rotate normally in the two second gear slots 14 respectively, and it is also ensured that when the servo motor 20 is started, the output shaft of the servo motor 20 can rotate normally in one of the second gear slots 14.

[0035] Example 5: This example provides a pressure-receiving device for processing stainless steel nut assemblies. In addition to the technical solutions of the above examples, it also has the following technical features, including: Two limiting grooves 21 are respectively opened on the inner wall of two movable grooves 6. Tensioning wheels 22 are slidably connected in both limiting grooves 21, and the two tensioning wheels 22 are respectively in contact with two synchronous belts 8. Two electric telescopic rods 23 are fixedly connected to two fixed plates 2 respectively, and the output shafts of the two electric telescopic rods 23 pass through the two fixed plates 2 respectively and extend into the two limiting grooves 21 and are fixedly connected to the two tensioning wheels 22.

[0036] In use, the user activates the electric telescopic rod 23, which drives the tensioning wheel 22 to move along the limiting groove 21. This causes the tensioning wheel 22 to compress the synchronous belt 8, ensuring that the user can control the tension of the synchronous belt 8 and prevent the synchronous belt 8 from becoming loose during long-term use.

[0037] Example 6: This example provides a pressure-retracting device for processing stainless steel nut assemblies. In addition to the technical solutions of the above examples, it also has the following technical features: the tensioning wheel 22 is slidably connected to the movable groove 6, and the output shaft of the electric telescopic rod 23 is slidably connected to the limiting groove 21.

[0038] Specifically, it is ensured that when the tensioning wheel 22 slides, the tensioning wheel 22 can slide normally within the movable groove 6, and that when the electric telescopic rod 23 is started, the output shaft of the electric telescopic rod 23 can slide normally within the limit groove 21.

[0039] Example 7: This example provides a pressure-receiving device for processing stainless steel nut assemblies. In addition to the technical solutions of the above examples, it also has the following technical features: two lead screws 5 are located in the slide groove 3 and are rotatably connected to the slide groove 3; the threads on several lead screws 5 have the same direction of rotation and the same thread pitch.

[0040] Specifically, it is ensured that when the two lead screws 5 rotate, the two lead screws 5 can rotate normally within the slide groove 3. Furthermore, because the threads on several lead screws 5 have the same direction of rotation and the same thread pitch, when several lead screws 5 rotate, the two support plates 4 will be moved downward simultaneously by the action of the threads of several lead screws 5.

[0041] Example 8: This example provides a pressure-receiving device for processing stainless steel nut assemblies. In addition to the technical solutions of the above examples, it also has the following technical features: the bottom ends of the two synchronous pulleys 7 are rotatably connected to the slide groove 3, the synchronous belt 8 is in contact with the inner wall of the movable groove 6, and the metal gasket 25 is a smooth stainless steel sheet with a thickness of 0.3mm.

[0042] Specifically, this design ensures that when the two synchronous pulleys 7 rotate, the bottom ends of the two synchronous pulleys 7 can rotate normally within the slide groove 3. Furthermore, because the synchronous belt 8 is in contact with the inner wall of the movable groove 6, when the synchronous belt 8 is driven between the two synchronous pulleys 7, it will be restricted by the inner wall of the movable groove 6 to prevent the problem of tooth stripping. At the same time, because the metal washer 25 is a smooth stainless steel sheet with a thickness of 0.3mm, several metal washers 25 can provide protection for the nut and prevent several support plates 24 from damaging the nut.

[0043] Working principle: In use, when several support plates 24 press against the nut, several metal washers 25 will protect the nut and prevent the several support plates 24 from damaging the nut; In use, the user starts the servo motor 20, causing its output shaft to drive the second connecting rod 19 to rotate within the second rotating slot 18. This causes the second connecting rod 19 to drive the two fourth bevel gears 16 to rotate within the two second gear slots 14. The two fourth bevel gears 16 then drive the two third bevel gears 15 to rotate within the two second gear slots 14. When the two third bevel gears 15 rotate, they will, via the two first connecting rods 17, drive the two second bevel gears 11 to rotate within the two first gear slots 9. The two second bevel gears 11 then drive the two first bevel gears 10 to... The rotation causes the two first bevel gears 10 to drive two of the synchronous pulleys 7 to rotate in the two movable slots 6, and the two synchronous pulleys 7 to drive the other two synchronous pulleys 7 to rotate through the two synchronous belts 8, so that several synchronous pulleys 7 rotate simultaneously. When several synchronous pulleys 7 rotate, several synchronous pulleys 7 will drive several lead screws 5 to rotate in the two support plates 4, so that the two support plates 4 will move downward simultaneously under the action of several lead screws 5 threads, so that the two fixed plates 2 will drive the worktable 1 to move upward relative to each other, so that the user can adjust the height of the worktable 1 according to the operator's working comfort. When in use, the user starts the electric telescopic rod 23, which drives the tensioning wheel 22 to move along the limiting groove 21. The tensioning wheel 22 squeezes the synchronous belt 8, ensuring that the user can control the tension of the synchronous belt 8 and prevent the synchronous belt 8 from loosening during long-term use.
