Description

Technical Field

[0001] This invention relates to the field of expansion nail processing technology, and in particular to an automatic expansion nail insertion device. Background Technology

[0002] Expansion nails consist of components such as a screw and an expansion tube. They are classified by material (metal or plastic) and by installation method (screw-in or hammer-out). The screw has a conical tail: the inner diameter of the cone is larger than the inner diameter of the expansion tube. When the nut is tightened, the screw moves outwards, and through the axial movement of the thread, the conical part moves, creating a large positive pressure on the outer circumference of the expansion tube. The small angle of the cone creates frictional self-locking between the wall, the expansion tube, and the cone, thus achieving a fixing effect. Expansion nails utilize the frictional force generated by the expansion due to the wedge-shaped inclination to achieve a fixing effect.

[0003] Existing expansion nails require the screw to be inserted into the sleeve before they can be used. This operation is usually done manually. When a large number of expansion nails are needed, the screws need to be inserted into the sleeve one by one by hand. This method of inserting nails is very inefficient and greatly increases the labor intensity of workers.

[0004] Based on this, we propose an automatic expansion nail insertion device. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic expansion nail insertion device.

[0010] Preferably, the drive assembly includes a motor and a one-way bearing. The motor is fixedly connected to the side wall of the base via a bracket. The one-way bearing is fixedly connected to the output end of the motor. One end of the lead screw passes through the side wall of the first housing and is fixedly connected to the one-way bearing.

[0011] Preferably, the drive assembly further includes a rotating rod, a first bevel gear, a second bevel gear, a driving wheel, and a driven wheel.

The end of the rotating rod near the rotating shaft passes through the side wall of the loading platform and is fixedly connected to the first bevel gear. The side wall of the rotating shaft is fixedly connected to the second bevel gear. The first bevel gear and the second bevel gear are meshed together. The driving wheel is fixedly connected to the side wall of the one-way bearing. The end of the rotating rod near the motor is fixedly connected to the driven wheel. The driving wheel is connected to the driven wheel via a synchronous belt.

[0012] Preferably, a discharge mechanism is installed on the base. The discharge mechanism includes a mounting plate, a second housing, a sliding plug, a horizontal plate, a discharge plate, a spring, and a connecting pipe.

[0018] 3. By setting up an unloading mechanism, the unloading plate will move automatically during the nail insertion process, automatically pushing the previously processed expansion nail out of the sleeve groove, thereby completing automatic unloading and further saving manpower.

[0025] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Reference Figures 1-5 An automatic expansion nail insertion device includes a base 1;

[0027] The automatic nail insertion mechanism includes a feeding platform 2, a screw groove 3, a screw box 4, a rotating shaft 5, a feeding turntable 6, a sleeve groove 7, a fixing rod 8, a sleeve box 9, a first housing 10, a sliding plate 11, a push rod 12, and a drive assembly. The feeding platform 2 is fixedly connected to the upper end of the base 1. A screw groove 3 is provided on the upper end of the feeding platform 2. The screw box 4 is fixedly connected to the upper end of the feeding platform 2 via a fixing shaft. A rotating shaft 5 is rotatably connected to the upper end of the base 1. The feeding turntable 6 is fixedly connected to the upper end of the rotating shaft 5. The base 1 has four sleeve slots 7, which are symmetrically arranged along the axis of rotation 5. A fixing rod 8 is fixedly connected to the upper end of the base 1. A sleeve box 9 is fixedly connected to the side wall of the fixing rod 8. A first box 10 is fixedly connected to the upper end of the base 1 through a vertical rod. A sliding plate 11 is slidably connected to the inner wall of the first box 10. A push rod 12 is fixedly connected to the side wall of the sliding plate 11 near the loading platform 2. One end of the push rod 12 passes through the side wall of the first box 10 and extends into the screw groove 3. A drive assembly is provided on the base 1.

[0028] The automatic pin insertion mechanism also includes a slider 13, a connecting rod 14, and a lead screw 15. The slider 13 is slidably connected to the inner wall of the first housing 10. Two connecting rods 14 are symmetrically fixed to the side wall of the slider 13 near the slide plate 11. The other end of each connecting rod 14 is fixedly connected to the side wall of the slide plate 11. The lead screw 15 is rotatably connected to the inner wall of the first housing 10. The side wall of the lead screw 15 is threadedly connected to the slider 13.

[0029] The drive assembly includes a motor 16 and a one-way bearing 17. The motor 16 is fixedly connected to the side wall of the base 1 via a bracket. The output end of the motor 16 is fixedly connected to the one-way bearing 17. One end of the lead screw 15 passes through the side wall of the first housing 10 and is fixedly connected to the one-way bearing 17.

[0030] Further, the screws are placed into the screw box 4 one by one, and the screws will be stacked vertically one by one. The bottom screw will fall into the screw groove 3. Similarly, the sleeves are placed into the sleeve box 9 one by one, and the sleeves are stacked one by one. The bottom sleeve will fall into the sleeve groove 7. Then, the drive motor 16 rotates in the forward direction. At this time, the motor 16 can drive the lead screw 15 to rotate through the one-way bearing 17, which in turn drives the slider 13 to slide to the right on the inner wall of the first box 10. The slider 13 drives the slide plate 11 to slide to the right through the connecting rod 14, which in turn drives the push rod 12 to move to the right, pushing the screw in the screw groove 3 to the right and inserting it into the corresponding sleeve, thus completing the automatic screw insertion.

[0031] The drive assembly also includes a rotating rod 18, a first bevel gear 19, a second bevel gear 20, a drive wheel 21, and a driven wheel 22. The rotating rod 18 is rotatably connected to the side wall of the loading platform 2. The end of the rotating rod 18 near the rotating shaft 5 passes through the side wall of the loading platform 2 and is fixedly connected to the first bevel gear 19. The second bevel gear 20 is fixedly connected to the side wall of the rotating shaft 5. The first bevel gear 19 and the second bevel gear 20 are meshed together. The drive wheel 21 is fixedly connected to the side wall of the one-way bearing 17. The driven wheel 22 is fixedly connected to the end of the rotating rod 18 near the motor 16. The drive wheel 21 is connected to the driven wheel 22 through a synchronous belt.

[0032] Furthermore, after an expansion nail is processed, the drive motor 16 rotates in the reverse direction, causing the lead screw 15 to reverse, which in turn causes the slider 13 to slide to the left. The slider 13 then causes the slide plate 11 to slide to the left and reset, which in turn causes the push rod 12 to slide to the left and reset. At this time, a new screw will fall into the screw groove 3. During this process, the one-way bearing 17 will synchronously drive the drive wheel 21 to rotate, which in turn drives the driven wheel 22 to rotate, which drives the rotating rod 18 to rotate, which drives the first bevel gear 19 to rotate, which drives the second bevel gear 20 to rotate. At this time, the rotating shaft 5 will rotate 90 degrees, rotating the next sleeve to be opposite the screw groove 3, ready for the next nail insertion. It can also automatically feed materials after processing, making it more convenient to use.

[0033] A material unloading mechanism is installed on the base 1. The material unloading mechanism includes a mounting plate 23, a second box 24, a sliding plug 25, a horizontal plate 26, a material unloading plate 27, a spring 28, and a connecting pipe 29. The mounting plate 23 is fixedly connected to the upper end of the base 1. The second box 24 is fixedly connected to the side wall of the mounting plate 23. The sliding plug 25 is slidably connected to the inner wall of the second box 24. The horizontal plate 26 is fixedly connected to the side wall of the sliding plug 25 near the feeding turntable 6. The other end of the horizontal plate 26 is set to penetrate the side wall of the second box 24. The material unloading plate 27 is rotatably connected to the side wall of the horizontal plate 26. The spring 28 is fixedly connected to the side wall of the material unloading plate 27. The other end of the spring 28 is fixedly connected to the lower end of the horizontal plate 26. The first box 10 is connected to the second box 24 through the connecting pipe 29.

[0034] A limiting plate 30 that cooperates with the unloading plate 27 is fixedly connected to the side wall of the horizontal plate 26.

[0035] Furthermore, during the insertion process, air inside the first housing 10 is forced into the second housing 24 through the connecting pipe 29, increasing the pressure inside the second housing 24. This pushes the sliding plug 25 to slide, causing the horizontal plate 26 to move, which in turn moves the unloading plate 27. At this time, the unloading plate 27 abuts against the previously processed expansion nail end, and the unloading plate 27 also abuts against the limiting plate 30 on the left and right sides of the spring 28. Consequently, the unloading plate 27 cannot rotate towards the limiting plate 30. The movement of the unloading plate 27 then pushes the expansion nail out of the sleeve groove 7, thus achieving automatic unloading. During the loading process, the one-way bearing 17 synchronously drives the active... The rotation of wheel 21 drives the driven wheel 22 to rotate, which in turn drives the rotating rod 18 to rotate, which in turn drives the first bevel gear 19 to rotate, which in turn drives the second bevel gear 20 to rotate. At this time, the rotating shaft 5 will rotate 90 degrees, rotating the next sleeve to be opposite the screw groove 3, ready for the next nail insertion. The previously processed expansion nail will rotate 90 degrees and move to directly below the horizontal plate 26. During the resetting process of the push rod 12, the air in the second box 24 will be extracted through the connecting pipe 29, thereby reducing the pressure in the second box 24. The sliding plug 25 will move and reset, which in turn drives the horizontal plate 26 to move and reset the unloading plate 27, so that the next unloading can be carried out.

[0036] The first housing 10 has a through hole on its inner wall near the motor 16, and the second housing 24 has a through hole on its inner wall near the mounting plate 23.

[0037] In this invention, the screws are first placed into the screw box 4 in sequence, and then the screws are stacked vertically one by one. The bottom screw will fall into the screw groove 3. Similarly, the sleeves are placed into the sleeve box 9 in sequence, and the sleeves are stacked one by one. The bottom sleeve will fall into the sleeve groove 7.

[0038] Next, the drive motor 16 rotates in the forward direction. At this time, the motor 16 can drive the lead screw 15 to rotate through the one-way bearing 17, which in turn drives the slider 13 to slide to the right on the inner wall of the first housing 10. The slider 13 drives the slide plate 11 to slide to the right through the connecting rod 14, which in turn drives the push rod 12 to move to the right, pushing the screw in the screw groove 3 to the right and inserting it into the corresponding sleeve.

[0039] During this process, the air in the first housing 10 is squeezed into the second housing 24 through the connecting pipe 29, thereby increasing the pressure in the second housing 24. This pushes the sliding plug 25 to slide, causing the horizontal plate 26 to move, which in turn causes the unloading plate 27 to move. At this time, the unloading plate 27 abuts against the previously processed expansion nail port, and the unloading plate 27 abuts against the limiting plate 30 on the left and right sides of the spring 28. As a result, the unloading plate 27 cannot rotate in the direction of the limiting plate 30. The movement of the unloading plate 27 will push the expansion nail out of the sleeve groove 7, thereby performing automatic unloading.

[0040] Once an expansion nail is processed, the drive motor 16 rotates in the reverse direction, causing the lead screw 15 to reverse, which in turn causes the slider 13 to slide to the left. The slider 13 then causes the slide plate 11 to slide to the left and reset, which in turn causes the push rod 12 to slide to the left and reset. At this time, a new screw will fall into the screw groove 3.

[0041] During this process, the one-way bearing 17 will synchronously drive the drive wheel 21 to rotate, which in turn drives the driven wheel 22 to rotate, drives the rotating rod 18 to rotate, drives the first bevel gear 19 to rotate, drives the second bevel gear 20 to rotate, and then the rotating shaft 5 will rotate 90 degrees to rotate the next sleeve to be opposite the screw groove 3, in preparation for the next nail insertion, while the previously processed expansion nail will rotate 90 degrees and move to directly below the horizontal plate 26.

[0042] During the reset process of the push rod 12, the air inside the second box 24 is extracted through the connecting pipe 29, thereby reducing the pressure inside the second box 24. The slide plug 25 moves to reset, which in turn moves the horizontal plate 26, causing the unloading plate 27 to move to reset, so that the next unloading can be carried out.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
