Description

Technical Field

[0001] This invention relates to the field of spacer bar riveting technology, specifically to a spacer bar riveting device that is easy to assemble. Background Technology

[0002] Smart grids rely on advanced sensing, communication, and digital control technologies to construct a new power transmission and distribution system, enabling efficient power transmission, real-time perception of operating status, and intelligent regulation. Smart grid spacers are core intelligent fittings for overhead split transmission lines. In addition to traditional functions such as fixing the spacing between split conductors, suppressing conductor vibrations from a breeze, secondary span oscillations and line galloping, preventing conductor whipping and wear, and ensuring electrical safety distances, they integrate sensor acquisition, wireless communication, and self-powered modules. They can monitor conductor vibration, body temperature, and operating stress data in real time and remotely upload this data to the operation and maintenance platform. This provides early warnings of abnormal line conditions, promoting the transformation of the power grid from periodic inspections to condition-based maintenance. They are widely used in smart transmission lines of various voltage levels, contributing to the digital and intelligent operation and maintenance of new power systems. Spacer riveting equipment is specifically designed for the production and assembly of transmission line spacers. Equipped with quick-adjustable positioning fixtures, it can easily complete the pre-assembly and positioning of spacer frames, clamps, and other components. Operation and debugging are simple, ensuring stable and uniform riveting, guaranteeing secure and consistent riveting points, effectively reducing the difficulty of manual assembly and improving the production efficiency of spacer assembly.

[0003] Chinese patent CN210997371U discloses a damping spacer riveting device, including a base plate, a worktable fixedly connected to the top of the base plate, four connecting columns fixedly connected to the top of the worktable, and a top plate fixedly connected to the top of the four connecting columns. An electric push rod extending to the outside of the top plate is fixedly installed inside the top plate, and a riveting plate is engaged with the output shaft of the electric push rod. This damping spacer riveting device works by placing the damping spacer inside the worktable and rotating two handles. The handles drive a threaded screw to rotate, bringing two mounting brackets closer together and ultimately securing the damping spacer with a clamping rod. Then, the electric push rod is activated, causing the riveting plate to press down and perform the riveting operation. The entire process is fast and accurate, effectively solving the problems of low efficiency and poor accuracy associated with manual riveting of damping spacers.

[0004] Although this technical solution can perform riveting work on spacer bars, the riveting process generates processing debris such as aluminum shavings. Existing riveting devices lack a matching debris collection structure, and the debris easily accumulates in the workpiece positioning area of ​​the worktable, thereby damaging the workpiece positioning reference, causing positioning failure, and affecting the accuracy of riveting processing. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a spacer bar riveting device that is easy to assemble, comprising:

[0006] A base, the top of which is fixedly connected to a fixed frame, the top of which is fixedly connected to a driving component, the output end of which is fixedly connected to a pressure plate, and the pressure plate is guided and slid through the support round shaft of the fixed frame, and the top of which is fixedly connected to an upper nail component.

[0007] The worktable is fixedly connected to the base. The side of the worktable is evenly provided with placement slots, and the inner side of the placement slot is fixedly connected with a positioning block. The inner side of the placement slot is evenly provided with through holes, and the bottom of the worktable is fixedly connected with a connecting component.

[0008] Furthermore, the connecting component includes a rectangular connecting box disposed at the bottom of the workbench, a through hole opened on the placement slot penetrating the top of the connecting box, the side of the connecting box being fixedly connected to the inner side of the base, and a negative pressure fan being fixedly connected to the bottom of the inner cavity of the connecting box.

[0009] Furthermore, it also includes a mesh plate fixedly connected to the inside of the connecting box, a cylinder fixedly connected to the middle of the bottom of the mesh plate, the output end of the cylinder fixedly connected to the bottom of the connecting shaft, and a bracket fixedly connected to the inside of the connecting box, with the connecting shaft slidably connected to the inside of the bracket, a material ejection mechanism fixedly connected to the top of the connecting shaft, and a cleaning mechanism fixedly connected to the side of the connecting shaft.

[0010] Furthermore, the top-feeding mechanism includes a top-feeding frame fixedly connected to the top of the connecting shaft. Top-feeding rods are fixedly connected to the sides of the top-feeding frame. Each top-feeding rod passes through the top of the base and is slidably connected to the inner side of the worktable. There are four top-feeding rods, all fixedly connected to the top of the top-feeding frame with the connecting shaft as the center. A one-way air inlet valve is fixedly connected to the middle of the side of each top-feeding rod. The one-way air inlet valve passes through a baffle and is fixedly connected to the inner side of the top-feeding rod. One-way air outlet valves are fixedly connected to both sides above the top-feeding rod, with the outlet end of the one-way air outlet valve located between the baffle and the top-feeding rod. A piston rod is slidably connected to the inner side of the top material rod. The bottom of the piston rod is fixedly connected to the top of the bracket. The top of the piston rod is slidably connected to the inner side of the top material rod. A cylindrical baffle is fixedly connected to the side of the top material rod. Air grooves are provided on both sides of the baffle. The cylinder drives the top material frame and the top material rod to rise and fall, automatically completing the ejection and unloading of the riveted spacer. With the relative movement between the top material rod and the piston rod, air is stored during rise and air is sprayed during fall. The airflow sprayed from the baffle air groove automatically blows and cleans the side wall of the top material rod, removing the processing debris that falls on the top material rod and preventing impurities from adhering and accumulating.

[0011] Furthermore, the cleaning mechanism includes a cleaning frame, the inner side of which is fixedly connected to the side of the connecting shaft. A connecting plate is provided diagonally on the inner side of the cleaning frame, and the side of the connecting plate is fixedly connected to the inner side of the cleaning frame. A sliding shaft is slidably connected to the top of the connecting plate, and a sliding frame is fixedly connected to the top of the sliding shaft. The side of the sliding frame slides in contact with the inner side of the cleaning frame. A connecting spring is sleeved on the sliding shaft, the top of the connecting spring is fixedly connected to the sliding frame, and the bottom of the connecting spring is fixedly connected to the top of the connecting plate. The cylinder output end drives the connecting shaft to move upward in the connecting box, and the connecting shaft synchronously drives the cleaning frame to move upward. The side of the cleaning frame moves close to the inner wall of the connecting box to clean the inner side of the connecting box. As the cleaning frame continues to move upward, the sliding frame on the inner side of the cleaning frame comes into close contact with the bottom of the support. The sliding frame moves downward relative to the cleaning frame through the sliding shaft on the connecting plate, while compressing the connecting spring on the sliding shaft. The relative movement of the two completes the self-cleaning of the inner side of the cleaning frame, preventing impurities from accumulating and adhering to the inside of the cleaning frame.

[0012] This invention provides a spacer bar riveting device that is easy to assemble. It has the following advantages:

[0013] 1. In this easy-to-assemble spacer bar riveting device, during the upward movement of the top rod, the top rod moves upward relative to the piston rod. Outside air is stored inside the top rod through a one-way air inlet valve. When the top rod returns to its original position, the piston rod compresses the internal gas. The pressurized gas is delivered to the space between the baffle and the top rod through a one-way air outlet valve, and finally sprayed outward through the air grooves opened on the baffle, forming a surrounding airflow to blow and self-clean the side wall of the top rod.

[0014] 2. This easy-to-assemble spacer bar riveting equipment uses a cylinder to drive the connecting shaft to move the top material frame and the top material rod upwards simultaneously, pushing out the spacer bars that have been riveted in the slot and unloading them, thus realizing automatic ejection of the workpiece and reducing manual handling.

[0015] 3. This easy-to-assemble spacer bar riveting device can continuously blow away aluminum chips and other processing impurities that fall and adhere to the surface of the top bar in a timely manner, avoiding the accumulation and solidification of debris on the outer wall of the top bar, and preventing impurities from repeatedly entering and exiting the placement slot with the top bar, causing workpiece scratches and clogging of the positioning slot.

[0016] 4. This easy-to-assemble spacer bar riveting device uses a cylinder-driven connecting shaft to synchronously raise and lower the cleaning frame. The side wall of the cleaning frame slides against the inner wall of the connecting box, which can scrape off the processing debris attached to the inner side of the connecting box in real time, preventing impurities from accumulating and clumping on the inner wall of the connecting box.

[0017] 5. In this easy-to-assemble spacer bar riveting device, after the cleaning frame moves upward to the bottom of the sliding frame and the support, the sliding frame slides downward relative to the cleaning frame by relying on the sliding shaft and compresses the connecting spring. The relative movement between the two realizes the self-cleaning of the inner side of the cleaning frame by the sliding frame, which can promptly scrape away the impurities retained inside the cleaning frame and prevent debris from accumulating and adhering to the cleaning frame.

[0029] Please see Figures 1-3The present invention provides a spacer bar riveting device that is easy to assemble:

[0030] The operator first places the spacer bar into the placement slot 7 of the workbench 6, and completes the positioning and assembly of the spacer bar by using the positioning blocks 8 evenly arranged in the placement slot 7.

[0031] Then, the rivet is installed on the spacer bar by the upper nail component 2 located on the base 1. The drive component 4 is activated, and the output end of the drive component 4 drives the pressure plate 5 to slide down along the support round shaft on the fixed frame 3 to perform riveting processing on the spacer bar and the rivet on it in the placement groove 7.

[0032] After the spacer bars are riveted, the spacer bars in the slot 7 of the worktable 6 are pushed out by the connecting component 9 to realize the workpiece unloading;

[0033] Example 1, please refer to Figures 4-5 The present invention also provides a spacer riveting device that is easy to assemble. When the spacer is ejected, the cylinder 96 is activated and the output end of the cylinder 96 drives the connecting shaft 98 to move upward along the inside of the connecting box 91.

[0034] The connecting shaft 98 synchronously drives the top material mechanism 95 to move upward, pushing out the spacer bar that has been riveted in the placement groove 7. At the same time, the connecting shaft 98 drives the cleaning mechanism 94 to move together, so that the cleaning mechanism 94 moves back and forth along the inner wall of the connecting box 91 to complete the inner wall cleaning.

[0035] After the operator removes the spacer, the negative pressure fan 92 can be started. The negative pressure fan 92 generates suction force, which sucks the residual processing debris in the placement groove 7 into the connecting box 91 through the through hole and collects it on the mesh plate 93. At the same time, when the spacer is placed in the placement groove 7 for riveting operation, the negative pressure fan 92 can be turned on, and the spacer can be attracted and fixed in the placement groove 7 by the negative pressure suction force.

[0036] Please see Figures 6-8 When the spacer bar is ejected, the output end of the cylinder 96 drives the connecting shaft 98 to move upward. The connecting shaft 98 drives the ejector frame 951 to move upward. The ejector frame 951 further drives the ejector rod 952 to rise synchronously, so that the ejector rod 952 moves upward along the inside of the connecting box 91 and the worktable 6, and ejects the spacer bar that has been riveted in the placement groove 7.

[0037] During the upward movement of the top material frame 951 and the top material rod 952, the piston rod 954 located inside the top material rod 952 slides upward relative to the top material rod 952, allowing external air to enter the top material rod 952 through the one-way air inlet valve 956 for temporary storage.

[0038] When the output end of cylinder 96 drives the top material frame 951 and the top material rod 952 to reset downwards, the top material frame 951 slides downwards along the piston rod 954, the piston rod 954 squeezes the gas inside the top material rod 952, and the compressed gas is discharged outwards through the one-way exhaust valves 957 on both sides of the top.

[0039] Airflow flows into the gap between the baffle 953 and the top rod 952, and is sprayed outward through the air grooves 955 evenly opened on the baffle 953 to self-clean the outer side of the top rod 952, preventing debris from remaining and adhering to the surface of the top rod 952 when collecting and placing impurities in the groove 7.

[0040] Please see Figures 9-10 When the output end of cylinder 96 drives the connecting shaft 98 to move upward in the connecting box 91, the connecting shaft 98 drives the cleaning frame 941 to move upward synchronously. The side wall of the cleaning frame 941 slides against the inner wall of the connecting box 91, completing the cleaning operation of the inner side wall of the connecting box 91.

[0041] As the cleaning frame 941 continues to rise, when the top of the sliding frame 942 inside the cleaning frame 941 abuts against the bottom of the support 97, the sliding frame 942 slides downward relative to the cleaning frame 941 through the sliding shaft 943 on the connecting plate 945, and compresses the connecting spring 944 sleeved on the sliding shaft 943.

[0042] The relative motion enables the sliding frame 942 to self-clean the inside of the cleaning frame 941, preventing impurities from accumulating and adhering to the inside of the cleaning frame 941.

[0043] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
