Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of polishing and grinding equipment, and particularly relates to a rotary flagpole polishing and grinding structure. Background Art
[0002] After the flagpole is welded and straightened, the exterior of the flagpole needs to be polished and ground. The polishing and grinding machine polishes and grinds from above, and while the flagpole is being polished, it is driven by the support wheels on both sides to rotate synchronously in a circular motion.
[0003] After the flagpole is polished and ground, it is necessary to first move the processed flagpole to one side, and then move the flagpole to be ground above the support wheels. The ground and unground flagpoles are imported and exported through the same path. The flagpole to be ground must wait until the ground flagpole is removed before it can be moved in. Moreover, since the flagpole is relatively long, the moving speed of the flagpole is relatively slow, resulting in a long flagpole replacement time. Summary of the Invention
[0004] An embodiment of the present disclosure relates to a rotary flagpole polishing and grinding structure. When the flagpole on top of the rotary drive wheel is polished and ground, the second support frame moves away from the first support frame, and the flagpole drops to the top of the middle export wheel below. The polished flagpole moves horizontally along the middle export wheel for export work. The flagpole to be ground moves from the side flagpole storage rack to the rotary drive wheel. The ground and unground flagpoles are imported and exported through two upper and lower paths, reducing the import time of the unground flagpole, improving the polishing and processing efficiency, and eliminating the problem that the ground and unground flagpoles are imported and exported through the same path in the prior art, resulting in a long flagpole replacement time because the unground flagpole can only be moved in after the ground flagpole is removed.
[0005] In a first aspect of the present disclosure, a rotary flagpole polishing and grinding structure is provided, which specifically includes: a main feeding frame, a side flagpole storage rack, a lower discharging support, and a polishing and grinding mechanism. A side flagpole storage rack is fixedly arranged on the upper part of the main feeding frame, a lower discharging support is fixedly arranged on the top of the main feeding frame, a polishing and grinding mechanism is arranged side by side on one side of the main feeding frame. A first support frame is fixedly arranged on the upper part of the main feeding frame, a second support frame is horizontally slidably arranged on the upper part of the main feeding frame. Side limit plates are fixedly arranged at both ends of the first support frame, and the side limit plates limit the axial position of the flagpole. Rotating rotary drive wheels are arranged at intervals in an array on the tops of the first support frame and the second support frame. Side displacement drive wheels are rotatably arranged at both ends of the main feeding frame. One of the rotary drive wheels and the side displacement drive wheels is driven to rotate by a motor, and the side displacement drive wheel is meshed and connected with a side displacement chain.
[0006] In at least some embodiments, the first support frame and the second support frame are arranged at intervals facing each other. The side flagpole storage rack is located outside the second support frame. The outside of the second support frame is fixedly connected to the telescopic rod of the side telescopic cylinder. The tail end of the side telescopic cylinder is fixedly connected to the main feeding frame. When the side telescopic cylinder shortens, the side telescopic cylinder pulls the second support frame to move away from the first support frame. After the distance between the second support frame and the first support frame is greater than the diameter of the flagpole, the flagpole falls onto the top of the middle guiding wheel below.
[0007] In at least some embodiments, vertically sliding front limiting blocks are arranged at intervals in the front of the side flagpole storage rack. The front limiting blocks are fixedly connected to the front part of the middle synchronous connecting rod. A rear pressing rod is rotatably arranged in cooperation with a rear shaft of the side flagpole storage rack. The rear pressing rod drives the middle synchronous connecting rod and the front limiting blocks to move downward, and the front limiting blocks move downward and no longer protrude to block the flagpole.
[0008] In at least some embodiments, the front part of the rear pressing rod is slidably connected to the rear chute of the middle synchronous connecting rod. The rear pressing rod presses the front limiting blocks to protrude to the upper part of the side flagpole storage rack. The front limiting blocks prevent the flagpole from rolling towards the side of the rotary driving wheel, realizing the limiting work of the flagpole. The side flagpole storage rack is arranged outside the second support frame, and the top of the side flagpole storage rack is higher than the rotary driving wheel.
[0009] In at least some embodiments, a middle guiding wheel is rotatably arranged in the middle of the lower discharging support. A synchronous gear shaft is fixedly arranged at the center of the middle guiding wheel. Adjacent synchronous gear shafts rotate synchronously through a belt. The middle guiding wheel rotates to move and guide the flagpole at the top.
[0010] In at least some embodiments, the synchronous gear shaft and the side displacement driving wheel rotate synchronously through a belt. The lower discharging supports are arranged at intervals on the top of the main feeding frame. The lower discharging supports are located at the interval between the first support frame and the second support frame. The flagpole falls onto the top of the middle guiding wheel below. The synchronous gear shaft and the middle guiding wheel rotate synchronously. The middle guiding wheel pushes the polished flagpole at the top to move. The middle guiding wheel rotates to perform the work of moving and guiding the polished flagpole at the top to the outside of the first support frame.
[0011] In at least some embodiments, the upper part of the polishing and grinding mechanism is rotatably connected in cooperation with the tail shaft of the grinding lifting frame. The upper part of the polishing and grinding mechanism is rotatably connected in cooperation with the shaft of the upper telescopic cylinder. The telescopic rod of the upper telescopic cylinder is rotatably connected in cooperation with the shaft of the grinding lifting frame. An electric grinding disc is rotatably arranged at the head end of the grinding lifting frame. The electric grinding disc is driven to rotate by a motor arranged at the head end of the grinding lifting frame. The bottom of the polishing and grinding mechanism is horizontally slidably connected to the track moving working surface.
[0012] In at least some embodiments, a lower synchronous connecting rod slides vertically below the polishing and grinding mechanism. The lower end of the lower synchronous connecting rod is rotatably connected to the side displacement chain. The side displacement chain moves in a cycle, and the lower synchronous connecting rod reciprocates with the side displacement chain. The lower synchronous connecting rod and the polishing and grinding mechanism move horizontally back and forth synchronously.
[0013] The present invention provides a rotary flagpole polishing and grinding structure, which has the following beneficial effects: When the flagpole on the top of the rotary drive wheel is polished and ground, the second support frame moves away from the first support frame, and the flagpole drops to the top of the middle guide wheel below. The polished flagpole moves horizontally along the middle guide wheel for export work. The flagpole to be polished moves from the side flagpole storage rack to the rotary drive wheel. The polished and unpolished flagpoles have two upper and lower paths for import and export work. The polished and unpolished flagpoles carry out the removal and insertion work at the same time, reducing the import time of the unpolished flagpole, improving the polishing processing efficiency, and eliminating the problem that the existing polished and unpolished flagpoles are imported and exported through one path, resulting in a long flagpole replacement time after the polished flagpole is removed before the unpolished flagpole can enter.
[0014] During the process of the side displacement drive wheel driving the side displacement chain to move, it simultaneously drives the synchronous gear shaft to rotate. The synchronous gear shaft and the middle guide wheel rotate synchronously. The middle guide wheel rotates to export the polished flagpole to the outside of the first support frame, eliminating the need for personnel to pull out the polished flagpole, reducing the manual operation process of personnel, and reducing the labor intensity of personnel.
[0015] The side flagpole storage rack can place the next flagpole to be polished in advance during the polishing process of one flagpole, reducing the waiting time for polishing, shortening the waiting time for flagpole polishing and replacement intervals, and improving the processing efficiency.

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
[0020] Embodiment 1: Please refer to Figures 1 to 8 : The present invention provides a rotary flagpole polishing and grinding structure, including: a main feeding frame 1, a side flagpole storage rack 2, a lower discharging support 3, and a polishing and grinding mechanism 4. A first support frame 101 is fixedly arranged on the upper part of the main feeding frame 1. A second support frame 102 is horizontally slidably arranged on the upper part of the main feeding frame 1. Side limiting plates 103 are fixedly arranged at both the head and tail sections of the first support frame 101. The side limiting plates 103 limit the axial position of the flagpole to prevent axial displacement of the flagpole. The side limiting plates 103 and the first support frame 101 are clamped and fixed by bolts and the position is moved by loosening the bolts to adapt to the limiting of flagpoles of different lengths. Rotating drive wheels 104 are arranged at intervals in an array at the tops of the first support frame 101 and the second support frame 102. Side displacement drive wheels 105 are rotatably arranged at both the head and tail of the main feeding frame 1. One of the rotating drive wheels 104 and the side displacement drive wheels 105 is driven to rotate by a motor. The side displacement drive wheels 105 are meshed and connected with a side displacement chain 106. A side flagpole storage rack 2 is fixedly arranged on the upper part of the main feeding frame 1. Front limiting blocks 201 that slide vertically are arranged at intervals in an array on the front side of the side flagpole storage rack 2. The front limiting blocks 201 are fixedly connected to the front part of a middle synchronous connecting rod 202. A rear pressing rod 203 is rotatably arranged at the rear side of the side flagpole storage rack 2 through a shaft. The rear pressing rod 203 drives the middle synchronous connecting rod 202 and the front limiting blocks 201 to move downward. The front limiting blocks 201 move downward and no longer protrude to block the flagpole. A lower discharging support 3 is fixedly arranged at the top of the main feeding frame 1. A middle guiding wheel 301 is rotatably arranged in the middle of the lower discharging support 3. The middle guiding wheel 301 has a V-shaped structure with an inner concave middle part. The middle guiding wheel 301 adapts to the arc surface structure of the flagpole. A synchronous gear shaft 302 is fixedly arranged at the center of the middle guiding wheel 301. Adjacent synchronous gear shafts 302 rotate synchronously through a belt. The middle guiding wheel 301 rotates to move and export the top flagpole. A polishing and grinding mechanism 4 is arranged side by side on one side of the main feeding frame 1. The upper part of the polishing and grinding mechanism 4 is rotatably connected with the tail shaft of a grinding lifting frame 401. The upper part of the polishing and grinding mechanism 4 is rotatably connected with the shaft of an upper telescopic cylinder 402. The telescopic rod of the upper telescopic cylinder 402 is rotatably connected with the shaft of the grinding lifting frame 401. An electric grinding disc 403 is rotatably arranged at the head end of the grinding lifting frame 401. The electric grinding disc 403 is driven to rotate by a motor arranged at the head end of the grinding lifting frame 401. The bottom of the polishing and grinding mechanism 4 is horizontally slidably connected with a track moving working surface 405. A lower synchronous connecting rod 404 slides vertically at the lower part of the polishing and grinding mechanism 4. The lower end of the lower synchronous connecting rod 404 is rotatably connected with the side displacement chain 106. The side displacement chain 106 moves in a cycle. The lower synchronous connecting rod 404 reciprocates with the side displacement chain 106. The lower synchronous connecting rod 404 and the polishing and grinding mechanism 4 move horizontally back and forth synchronously. The polishing and grinding mechanism 4 adjusts the axial grinding position of the flagpole.
[0021] In the embodiments of the present disclosure, as shown in the attached Figure 1 、 2As shown in FIGS. 3, 5, and 6, the first support frame 101 and the second support frame 102 are arranged at intervals facing each other. The side flagpole storage rack 2 is located outside the second support frame 102. The outside of the second support frame 102 is fixedly connected to the telescopic rod of the side telescopic cylinder 107. The tail end of the side telescopic cylinder 107 is fixedly connected to the main feeding rack 1. When the side telescopic cylinder 107 shortens, the side telescopic cylinder 107 pulls the second support frame 102 to move away from the first support frame 101. After the distance between the second support frame 102 and the first support frame 101 is greater than the diameter of the flagpole, the flagpole drops to the top of the middle guiding wheel 301 below. The polished flagpole moves horizontally along the middle guiding wheel 301 for guiding work. Then, the side telescopic cylinder 107 pushes the second support frame 102 to move back and close to the first support frame 101. The flagpole to be polished moves from the side flagpole storage rack 2 to the rotary driving wheel 104, and the unpolished flagpole moves from above to the rotary driving wheel 104. The polished and unpolished flagpoles have upper and lower paths for importing and exporting work, and the polished and unpolished flagpoles carry out the work of moving out and moving in at the same time, shortening the replacement time of the flagpole and improving the polishing processing efficiency.
[0022] In the embodiment of the present disclosure, as shown in the attached Figure 1 , 2 , 3, and 4, the front part of the rear pressure rod 203 is slidably connected to the rear chute of the middle synchronous link 202. The rear pressure rod 203 presses the front limit stop 201 to protrude to the upper part of the side flagpole storage rack 2. The front limit stop 201 prevents the flagpole from rolling towards the rotary driving wheel 104 side, realizing the limiting work of the flagpole. The side flagpole storage rack 2 is arranged outside the second support frame 102. The top of the side flagpole storage rack 2 is higher than the rotary driving wheel 104. The side flagpole storage rack 2 can place the next flagpole to be polished in advance during the flagpole polishing process.
[0023] In the embodiment of the present disclosure, as shown in the attached Figure 1 , 2 , 3, 5, 6, and 7, the synchronous gear shaft 302 and the side displacement driving wheel 105 rotate synchronously through a belt. The lower discharge brackets 3 are arranged at intervals on the top of the main feeding rack 1. The lower discharge brackets 3 are located at the interval between the first support frame 101 and the second support frame 102. The flagpole drops to the top of the middle guiding wheel 301 below. The synchronous gear shaft 302 and the middle guiding wheel 301 rotate synchronously. The middle guiding wheel 301 pushes the polished flagpole on the top to move. The middle guiding wheel 301 rotates to carry out the moving and guiding work of the polished flagpole to the outside of the first support frame 101, eliminating the need for personnel to pull out the polished flagpole.
[0024] Embodiment 2. On the basis of Embodiment 1, a middle export wheel 301 is arranged between the lower discharge brackets 3 of the main feed rack 1 through spring support. The spiral spring supports the middle export wheel 301 to move upward and approach the flagpole at the top of the rotary drive wheel 104. The flagpole falls onto the middle export wheel 301 and compresses the support spring. The spiral spring buffers the pressure of the flagpole falling, reduces the impact force when the flagpole falls, and avoids the situation that the flagpole is collided and dented due to excessive falling force during the falling process.
[0025] The working principle of this embodiment: The flagpole is placed at the top of the rotary drive wheel 104. The side displacement drive wheel 105 drives the side displacement chain 106 to rotate in a cycle. The side displacement chain 106 drives the polishing and grinding mechanism 4 to move horizontally along the track moving working surface 405 through the lower synchronous connecting rod 404. The upper telescopic cylinder 402 shortens to support the grinding lifting frame 401 to fall. The electric grinding disc 403 at the head end of the grinding lifting frame 401 falls and fits with the flagpole at the top of the rotary drive wheel 104 to perform the flagpole grinding work. The rotary drive wheel 104 drives the flagpole to rotate circumferentially. The flagpole rotates circumferentially and the electric grinding disc 403 adjusts the grinding position to achieve rotary grinding. When the flagpole at the top of the rotary drive wheel 104 is polished and ground, the side telescopic cylinder 107 shortens. The side telescopic cylinder 107 pulls the second support frame 102 to move away from the first support frame 101. After the distance between the second support frame 102 and the first support frame 101 is greater than the diameter of the flagpole, the flagpole falls onto the top of the lower middle export wheel 301. The polished flagpole moves horizontally along the middle export wheel 301 for export work. Then the side telescopic cylinder 107 pushes the second support frame 102 to move back and approach the first support frame 101. The flagpole to be ground moves from the side flagpole storage rack 2 to the rotary drive wheel 104, and the unground flagpole moves from above to the rotary drive wheel 104. The ground and unground flagpoles have upper and lower two paths for import and export work. The ground and unground flagpoles perform the removal and entry work at the same time, eliminating the problem that the existing ground and unground flagpoles are carried out by one path and both are imported and exported from above, resulting in a long flagpole replacement time. The two paths of this structure can reduce the import time of the unground flagpole and improve the grinding processing efficiency of the flagpole; The side flagpole storage rack 2 can place the next flagpole to be polished in advance during the flagpole polishing process. The rear pressing rod 203 presses the front limit stop 201 to protrude above the side flagpole storage rack 2. The front limit stop 201 prevents the flagpole from rolling towards the rotary drive wheel 104, realizing the limiting work of the flagpole. When the top of the rotary drive wheel 104 is vacated, the rear part of the rear pressing rod 203 is lifted upwards. The rear pressing rod 203 drives the middle synchronous connecting rod 202 and the front limit stop 201 to move downwards. The front limit stop 201 moves down and no longer protrudes to block the flagpole, realizing that the rear pressing rod 203 pushes the flagpole to move to the top of the rotary drive wheel 104. During the flagpole polishing process, the next flagpole to be polished can be placed in advance, reducing the waiting time for polishing, shortening the waiting time for flagpole polishing and replacement, and improving the processing efficiency of flagpole polishing and polishing. During the process of the side displacement drive wheel 105 driving the side displacement chain 106 to move, the synchronous gear shaft 302 is driven to rotate through a belt at the same time. The synchronous gear shaft 302 and the middle guide wheel 301 rotate synchronously. The middle guide wheel 301 pushes the polished flagpole at the top to move. The middle guide wheel 301 rotates to perform the moving and guiding work of the polished flagpole at the top to the outside of the first support frame 101, eliminating the work of manually pulling out the polished flagpole by personnel, reducing the manual operation process of personnel, and reducing the labor intensity of personnel.
