[0001] This utility model belongs to the field of switch assembly technology, specifically relating to a switch drive rod assembly device. Background Technology

[0002] In today's electrical equipment manufacturing industry, switches are key components for controlling the opening and closing of circuits and ensuring the safe and stable operation of power systems. The quality and efficiency of their manufacturing are of great concern. The performance of a switch largely depends on the assembly precision and reliability of its internal components. Among them, the drive rod is the core transmission component that realizes the operation of the switch. Its assembly process is crucial. During the assembly of the switch drive rod, washers need to be placed on the drive rod. This operation is relatively simple and is generally done manually. The manual assembly method of placing washers on the drive rod is greatly affected by human factors. Performing this work for a long time can easily cause visual fatigue, making it difficult to ensure that the washers are placed accurately each time, thus affecting the efficiency of the switch drive rod assembly.

[0003] Therefore, a switch drive rod assembly device is designed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a switch drive rod assembly device, comprising a U-shaped base and a bracket fixedly connected to the upper surface of the U-shaped base. A material bucket is inserted into a circular hole on the upper surface of the bracket. A square plate is inserted inside the U-shaped base. An L-shaped rod is inserted into a horizontal groove inside the square plate. When the L-shaped rod moves horizontally, it drives the square plate to move and / or slides within the square plate. The L-shaped rod drives the square plate to move, thereby driving the drive rod to the bottom of the material bucket. The L-shaped rod slides within the square plate to move the material bucket longitudinally, thereby resetting the washer inside the material bucket after it is fitted onto the drive rod.

[0006] As a preferred embodiment of the switch drive rod assembly equipment of this utility model, an electric push rod is installed in the mounting groove opened on the upper surface of the bracket. An upper U-shaped block is fixedly connected to the end of the piston rod of the electric push rod, and a lower U-shaped block is fixedly connected to one end of the L-shaped rod. A diagonal rod is inserted inside the upper U-shaped block, and the other end of the diagonal rod is inserted into the lower U-shaped block. The two ends of the diagonal rod are rotatably connected to the upper U-shaped block and the lower U-shaped block respectively through a shaft pin.

[0007] As a preferred embodiment of the switch drive rod assembly equipment of this utility model, a rod mold is inserted into the mold groove opened on the upper surface of the square plate, a bottom groove is opened on the bottom surface of the material barrel, and a side groove connected to the bottom groove is opened on the circumferential surface of the material barrel.

[0008] As a preferred embodiment of the switch drive rod assembly equipment of this utility model, a top rod and a bottom rod are fixedly connected to the surface of the material barrel. The top rod is located above the bottom rod. A longitudinal rod is provided between the top rod and the bottom rod. The longitudinal rod is inserted longitudinally into a sliding groove opened on the upper surface of the bracket. The longitudinal rod and the bracket are slidably connected. A connecting plate is fixedly connected to the surface of the longitudinal rod. The other end of the connecting plate is fixedly connected to the upper U-shaped block.

[0009] As a preferred embodiment of the switch drive rod assembly equipment of this utility model, a connecting plate is fixedly connected to the surface of the material barrel, the connecting plate is located above the support, a second spring is fixedly connected between the connecting plate and the support, and the side of the connecting plate away from the material barrel is in contact with the surface of the longitudinal rod.

[0010] As a preferred embodiment of the switch drive rod assembly equipment of this utility model, a spring three and an inner plate two are provided in the connecting groove opened inside the bracket. The two ends of the spring three are fixedly connected to the inner plate two and the bracket respectively. The inner plate two and the bracket are slidably connected. A hemisphere is fixedly connected to the side of the inner plate two away from the spring three. The hemisphere is inserted into the lower groove opened on the surface of the material barrel. The surface of the material barrel is provided with an upper groove, which is located above the lower groove.

[0011] As a preferred embodiment of the switch drive rod assembly equipment of this utility model, the square plate has a rectangular groove that communicates with the horizontal groove inside. The rectangular groove has an inner plate and a spring inside. The two ends of the spring are fixedly connected to the square plate and the inner plate, respectively. The inner plate and the square plate are slidably connected. Multiple triangular blocks are fixedly connected at equal intervals on the upper surface of the inner plate. Multiple triangular grooves are formed at equal intervals on the bottom surface of the L-shaped rod.

[0012] As a preferred embodiment of the switch drive rod assembly equipment of this utility model, the U-shaped base is internally fixedly connected with a left baffle and a right baffle.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by driving the upper U-shaped block, the inclined rod and the L-shaped rod in linkage by the electric push rod, the drive rod in the square plate and rod mold is automatically moved to the bottom of the material barrel, and then the gasket is installed by the longitudinal movement of the material barrel. The whole process does not require manual intervention. Compared with traditional manual assembly, it can significantly reduce the operation time and improve the efficiency of mass production. It is especially suitable for the standardized assembly of large-scale switch drive rods. When the square plate moves, the left and right baffles act as limiters to ensure that the drive rod can be accurately positioned directly below the material bucket each time, avoiding misalignment of the gasket due to positional deviation. Spring 1 pushes the triangular block on the inner plate 1 to engage with the triangular groove of the L-shaped rod, achieving flexible linkage between the L-shaped rod and the square plate. This ensures power transmission while avoiding wear on components caused by rigid collisions. Spring 3 pushes the hemisphere on the inner plate 2 to engage with the lower or upper groove of the material bucket, precisely limiting the upper and lower limit positions of the material bucket and ensuring that the washer is properly fitted and reset. When the square plate contacts the right baffle, the material bucket returns to its original position, and the L-shaped rod slides inside the square plate. At this time, the drive rod with the washer already fitted can be quickly removed and a new part to be assembled can be placed in. There is no need to stop the machine and wait, which realizes continuous production and reduces the interval time between processes. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Embodiments like Figures 1 to 9 As shown; A switch drive rod assembly device includes a U-shaped base 1 and a bracket 2 fixedly connected to the upper surface of the U-shaped base 1. A material bucket 15 is inserted into a circular hole on the upper surface of the bracket 2. A square plate 3 is inserted inside the U-shaped base 1. An L-shaped rod 9 is inserted into a horizontal groove 22 inside the square plate 3. When the L-shaped rod 9 moves horizontally, it drives the square plate 3 to move and / or slides within the square plate 3. The movement of the square plate 3 by the L-shaped rod 9 drives the drive rod to move to the bottom of the material bucket 15. The sliding of the L-shaped rod 9 within the square plate 3 causes the material bucket 15 to move longitudinally, thereby placing the washer inside the material bucket 15 onto the drive rod and resetting it.

[0016] In this implementation plan: the dual motion mode of the L-shaped rod 9 enables precise feeding of the drive rod and coordinated action of the material bucket 15, providing a continuous mechanical transmission basis for the installation of the washer and ensuring the orderly connection of the assembly process.

[0017] Furthermore: In an optional embodiment, an electric push rod 5 is installed in the mounting groove on the upper surface of the bracket 2. The end of the piston rod of the electric push rod 5 is fixedly connected to an upper U-shaped block 6, and one end of the L-shaped rod 9 is fixedly connected to a lower U-shaped block 8. A diagonal rod 7 is inserted inside the upper U-shaped block 6, and the other end of the diagonal rod 7 is inserted into the lower U-shaped block 8. The two ends of the diagonal rod 7 are rotatably connected to the upper U-shaped block 6 and the lower U-shaped block 8 respectively through a shaft pin.

[0018] In this implementation plan: the power provided by the electric push rod 5 is converted into the horizontal movement of the L-shaped rod 9 through the linkage structure of the upper U-shaped block 6, the inclined rod 7 and the lower U-shaped block 8, thereby realizing the efficient transmission and direction conversion of power and providing a stable power source for the automated operation of the equipment.

[0019] Furthermore: In an optional embodiment, a rod mold 4 is inserted into a mold groove on the upper surface of the square plate 3, a bottom groove 31 is provided on the bottom surface of the material barrel 15, and a side groove 32 connected to the bottom groove 31 is provided on the circumferential surface of the material barrel 15.

[0020] In this implementation scheme: the rod mold 4 can fix and limit the drive rod, and the matching design of the bottom groove 31 and the side groove 32 can accurately guide the washer to detach from the material bucket 15 and be fitted onto the drive rod, which not only ensures the stable positioning of the drive rod, but also realizes the orderly assembly of the washer.

[0021] Furthermore: In an optional embodiment, a top rod 16 and a bottom rod 17 are fixedly connected to the surface of the material bucket 15. The top rod 16 is located above the bottom rod 17. A longitudinal rod 21 is provided between the top rod 16 and the bottom rod 17. The longitudinal rod 21 is inserted longitudinally into a groove opened on the upper surface of the support 2. The longitudinal rod 21 and the support 2 are slidably connected. A connecting plate 20 is fixedly connected to the surface of the longitudinal rod 21. The other end of the connecting plate 20 is fixedly connected to the upper U-shaped block 6.

[0022] In this implementation scheme: the movement of the upper U-shaped block 6 is synchronously transmitted to the material bucket 15 through the contact linkage of the top rod 16, the bottom rod 17 and the longitudinal rod 21, so as to realize the action coordination between the L-shaped rod 9 and the material bucket 15 and ensure that the position of the drive rod and the material bucket 15 correspond when the washer is put on.

[0023] Furthermore: In an optional embodiment, a connecting plate 18 is fixedly connected to the surface of the material bucket 15. The connecting plate 18 is located above the support 2. A spring 2 19 is fixedly connected between the connecting plate 18 and the support 2. The side of the connecting plate 18 away from the material bucket 15 is in contact with the surface of the longitudinal rod 21.

[0024] In this implementation scheme: Spring 2 19 applies continuous elastic pressure to the material bucket 15 through the connecting plate 18, ensuring that the vertical rod 21 is always in close contact with the bottom rod 17 when it moves down, avoiding action delay or misalignment caused by gaps, and improving the reliability of mechanical linkage.

[0025] Furthermore: In an optional embodiment, a spring 29 and an inner plate 28 are provided in the connecting groove 30 inside the bracket 2. The two ends of the spring 29 are fixedly connected to the inner plate 28 and the bracket 2, respectively. The inner plate 28 and the bracket 2 are slidably connected. A hemisphere 27 is fixedly connected to the side of the inner plate 28 away from the spring 29. The hemisphere 27 is inserted into the lower groove 26 opened on the surface of the material bucket 15. An upper groove 25 is opened on the surface of the material bucket 15, and the upper groove 25 is located above the lower groove 26.

[0026] In this implementation plan: During the downward movement of the material bucket 15, the connecting plate 18 compresses the second spring 19. Under the action of the second spring 19, the bottom end of the longitudinal rod 21 and the bottom rod 17 are always in contact during the downward movement of the material bucket 15. This avoids the problem of misalignment of the bottom gaskets caused by the sudden drop of the material bucket 15 due to the large number of gaskets inside the material bucket 15 under the action of gravity, thus improving the stability of the equipment during use.

[0027] Furthermore: In an optional embodiment, a rectangular groove 13 communicating with the transverse groove 22 is provided inside the square plate 3. An inner plate 11 and a spring 12 are provided inside the rectangular groove 13. The two ends of the spring 12 are fixedly connected to the square plate 3 and the inner plate 11 respectively. The inner plate 11 and the square plate 3 are slidably connected. A plurality of triangular blocks 14 are fixedly connected at equal intervals on the upper surface of the inner plate 11. A plurality of triangular grooves 10 are provided at equal intervals on the bottom surface of the L-shaped rod 9.

[0028] In this implementation scheme: Spring 12 pushes the triangular block 14 to engage with the triangular groove 10, which can realize the flexible linkage between the L-shaped rod 9 and the square plate 3. This ensures the effectiveness of power transmission and allows the L-shaped rod 9 to slide independently after the square plate 3 is in place, reserving movement space for the subsequent washer fitting action.

[0029] Furthermore: In an optional embodiment, a left baffle 23 and a right baffle 24 are fixedly connected inside the U-shaped seat 1.

[0030] In this implementation scheme: the left baffle 23 and the right baffle 24 can precisely limit the movement range of the square plate 3, ensuring that the drive rod can accurately reach the assembly position or material pick-up / drop position below the material bucket 15 each time, avoiding component collisions or assembly deviations caused by excessive movement.

[0031] Working principle: When the device installs washers on the surface of the switch drive rod, the inside of the material bucket 15 matches the shape of the washers, so that multiple washers are placed in an orderly manner inside the material bucket 15. The width of the bottom groove 31 is smaller than the diameter of the washers, and the width of the bottom groove 31 is larger than the diameter of the top of the switch drive rod. The width of the side groove 32 is larger than the diameter of the washers, which makes it easy for the bottom washers to slide out from the inside of the side groove 32. At the same time, it can make the washers placed in an orderly manner inside the material bucket 15 and prevent them from falling downwards. Connect the device to an external power source and insert the switch drive rod into the rod mold 4. At this time, the top of the switch drive rod is higher than the upper surface of the rod mold 4. Start the electric push rod 5 through the external controller, which in turn causes the piston rod of the electric push rod 5 to move back and forth. During the movement of the piston rod of the electric push rod 5, it drives the upper U-shaped block 6 to move synchronously. When the upper U-shaped block 6 moves downward, the upper U-shaped block 6 drives the L-shaped rod 9 to move towards the left baffle 23 through the inclined rod 7. Under the action of the elastic potential energy of the spring 12, the triangular block 14 is inserted into the inside of the triangular groove 10, and there is a suitable force between the triangular block 14 and the L-shaped rod 9. At this time, the movement of the L-shaped rod 9 can drive the square plate 3 to slide inside the U-shaped seat 1. The movement of the square plate 3 drives the switch drive rod to move synchronously until one side of the square plate 3 is in contact with the left baffle 23. At this time, the switch drive rod moves to the bottom of the material bucket 15, and at this time the bottom end of the vertical rod 21 is in contact with the surface of the bottom rod 17. As the upper U-shaped block 6 continues to move downward, the L-shaped rod 9 slides inside the square plate 3, which in turn causes the triangular block 14 to slide on the bottom surface of the L-shaped rod 9. The movement of the upper U-shaped block 6 drives the bottom rod 17 to move downward synchronously, which in turn causes the hemisphere 27 to slide out from inside the lower groove 26. When the hemisphere 27 is inserted into the upper groove 25, the piston rod of the electric push rod 5 moves to its limit. Under the action of the elastic potential energy of the spring 29, when the hemisphere 27 is inserted into the upper groove 25, the position of the material bucket 15 can be fixed, so that the switch drive rod is inserted into the bottom groove 31 and into the bottom washer inside the material bucket 15. When the piston rod of the electric push rod 5 drives the upper U-shaped block 6 to move upward, the upward movement of the upper U-shaped block 6 drives the vertical rod 21 to move upward synchronously, and under the action of the inclined rod 7, it drives the L-shaped rod 9 to move towards the right baffle 24. At this time, the movement of the L-shaped rod 9 drives the switch drive rod to move synchronously towards the right baffle 24. During the movement of the switch drive rod, it can drive the bottom washer in the material barrel 15 to slide out from the inside of the side groove 32 until one side of the square plate 3 contacts the right baffle 24. At this time, the vertical rod 21... The top of the L-shaped rod 9 is in contact with the top rod 16. As the upper U-shaped block 6 moves upward, the L-shaped rod 9 can slide and reset inside the square plate 3, and the material bucket 15 can slide and reset upward. When the square plate 3 and the right baffle 24 are in contact, the gap between the upward movement of the material bucket 15 and the movement of the L-shaped rod 9 inside the square plate 3 allows the switch drive rod with the washer in the rod mold 4 to be removed and another switch drive rod with the washer to be installed to be placed, ensuring the continuity of the washer on the switch drive rod during the use of the equipment. The process of manually inserting the switch drive rod into the rod mold 4 is simpler than the process of manually fitting the washer onto the switch drive rod. After inserting the switch drive rod into the rod mold 4, activating the electric push rod 5 will achieve the effect of fitting the washer onto the switch drive rod, thus improving the efficiency of switch drive rod assembly.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
