Description

Technical Field

[0001] The invention relates to the technical field of roller polishing, in particular to an automatic roller surface polishing device. Background Art

[0002] Rollers are important mechanical parts used in the rolling process. They are mainly used for rolling and forming metals. Rollers are mainly composed of a roll body and a mounting end. Fig. 9 As shown, when metal profiles such as pipes and angle steels need to be rolled, the roller body is usually provided with a plurality of V-shaped grooves evenly arranged along its axial direction, and the roller usually needs to be polished to improve the rolling performance of the roller.

[0003] Regarding roller polishing, the invention patent with publication number CN117226697A discloses a cast roller polishing processing device, which realizes rotational grinding of the surface of the cast roller by rotating multiple polishing rollers. At the same time, the annular frame can move axially relative to the cast roller, and the cast roller is driven to rotate by a driving roller to achieve sufficient and efficient polishing of the cast roller. The arranged polishing roller can be flexibly adjusted in position by an extended transmission assembly to ensure that the polishing roller fits the surface of the cast roller, which greatly improves the polishing effect of the cast roller.

[0004] The above technical solution has the following problems during polishing: 1. When polishing the surface of the roller, in order to ensure the polishing effect, the polishing roller usually needs to apply a certain pressure to the surface of the roller. When polishing the V-groove surface of the roller, the pressure applied by the polishing roller on the surface of the roller cannot be controlled. If the pressure applied by the polishing roller on the surface of the roller is too large, the V-groove of the roller may be worn. If the pressure applied by the polishing roller on the surface of the roller is too small, it may cause incomplete polishing, which in turn leads to a decrease in the surface quality of the polished roller; 2. There may be hard particles such as metal debris on the surface of the roller. When polishing the roller, the hard particles are likely to scratch the surface of the roller, further reducing the surface quality of the roller; 3. When polishing the roller, impurities generated by polishing are likely to accumulate in the V-groove of the roller, which requires manual cleaning of the roller, resulting in a decrease in the polishing efficiency of the roller.

[0038] It should be noted that the reciprocating member 32 in the present invention includes a threaded rod, which is connected to the slide 31 by threaded cooperation, and the threaded rod is rotatably connected to the base 1. The right end of the threaded rod is connected to the output shaft of the reciprocating motor fixedly installed in the base 1. The reciprocating motor is controlled to drive the threaded rod to rotate reciprocally, so that the slide 31 moves back and forth left and right. At the same time, the reciprocating movement stroke of the slide 31 is adjusted by controlling the frequency of the reciprocating rotation of the reciprocating motor.

[0039] The polishing unit 3 is used for polishing the roller; specifically, after the roller is clamped and fixed, the reciprocating member 32 is controlled to drive the polishing machine 36 to move to the left end of the roller body through the pressure mechanism 35, and then the pressure mechanism 35 is controlled to make the polishing machine 36 apply a certain pressure to the roller surface, and then the polishing machine 36 is started to polish the roller surface, and at the same time, the reciprocating member 32 is controlled to drive the base 1 to move back and forth left and right according to the circumferential length of the roller body, so that the base 1 drives the polishing machine 36 to move back and forth left and right through the pressure mechanism 35, so that the polishing machine 36 can The polishing machine 36 can polish the surface of the roller, and when the polishing machine 36 moves to the corresponding position of the V-groove of the roller, the polishing machine 36 can polish the V-groove of the roller with a constant pressure under the cooperation of the matching mechanism 37 and the pressure mechanism 35, ensuring the polishing effect of the polishing machine 36 on the V-groove of the roller and preventing the V-groove of the roller from being worn due to excessive pressure. After polishing is completed, the pressure mechanism 35 is controlled to make the polishing machine 36 stop applying pressure to the surface of the roller, and the reciprocating part 32 is controlled to drive the polishing machine 36 to return to the initial position through the pressure mechanism 35.

[0040] See also Figure 3-Figure 5 The pressurizing mechanism 35 includes a transmission plate 351 distributed in the middle part above the slide 31, the rear side of the lower end of the transmission plate 351 is set as an inclined surface, the lower end of the transmission plate 351 is connected to the slide 31 for sliding up and down through multiple connecting rods 352, an electric push rod 353 is fixedly installed in the middle part of the upper end of the transmission plate 351, and a square block 354 is fixedly installed on the upper end of the electric push rod 353. Two pressurizing spring rods 355 arranged symmetrically on the left and right are installed on the upper end of the square block 354 for sliding up and down, and the upper ends of the multiple pressurizing spring rods 355 all slide up and down, penetrate the integrated plate 34 and are connected to the polishing machine 36.

[0041] The mating mechanism 37 includes a mating block 371 which is slidably installed on the rear side of the upper end of the slide seat 31. The front side of the upper end of the mating block 371 is configured to be a sloped surface used to cooperate with the sloped surface of the transmission plate 351 to drive the transmission plate 351 to move upward. A slide plate 373 is installed on the front end of the mating block 371 through a connecting spring 372, and the slide plate 373 is slidably connected to the slide seat 31 front and back. An electric telescopic rod 374 is connected between the slide plate 373 and the slide seat 31. A square plate 375 is fixedly installed on the rear side of the upper end of the mating block 371. The upper end of the square plate 375 slides back and forth and penetrates the integrated board 34. A probe 376 is fixedly installed on the front side of the upper end of the square plate 375.

[0042] It should be noted that the elastic force of the connecting spring 372 in the present invention is much greater than the elastic force of the pressure spring rod 355, and the inclined surface of the transmission plate 351 and the inclined surface of the matching block 371 in the present invention are both set to 45 degrees, so that when the probe 376 moves left and right for a distance, the polisher 36 can move up and down for a distance synchronously, that is, when the probe 376 is attached to the surface of the roller, the polisher 36 can also be attached to the surface of the roller. At the same time, the probe 376 in the present invention is made of a material with a hardness less than that of the roller material, thereby preventing the probe 376 from scratching the surface of the roller.

[0043] The pressure mechanism 35 is used to make the polisher 36 apply a certain pressure to the roller, and the matching mechanism 37 is used to cooperate with the pressure mechanism 35 to make the polisher 36 apply a constant pressure to the roller; specifically, firstly, the electric telescopic rod 374 is controlled to drive the slide plate 373 to move to the front limit position, so that the slide plate 373 drives the matching block 371 to move forward through the connecting spring 372, and the matching block 371 drives the probe 376 to move forward through the square plate 375, and when the probe 376 moves to the roller surface, the probe 376 passes through the square plate under the blocking effect of the roller. 375 finally stretches the connecting spring 372, and at the same time, the inclined surface of the matching block 371 and the inclined surface of the transmission plate 351 cooperate to drive the transmission plate 351 to move upward, so that the transmission plate 351 finally drives the polishing machine 36 to fit the lower side of the roller through the electric push rod 353, and then controls the electric push rod 353 to drive the square block 354 to move upward, so that the square block 354 can compress the pressure spring rod 355, and adjust the pressure applied by the polishing machine 36 to the surface of the roller by the compression amount of the pressure spring rod 355, so as to ensure the polishing quality of the roller by the polishing machine 36.

[0044] When the polisher 36 moves to the corresponding position of the V-groove of the roller, the probe 376 also moves to the corresponding position of the V-groove of the roller. At the same time, the probe 376 and the matching block 371 can move towards the roller under the action of the connecting spring 372, so that the probe 376 always fits the surface of the V-groove of the roller, and the inclined surface of the matching block 371 and the inclined surface of the transmission plate 351 cooperate to drive the transmission plate 351 to move upward, so that the polisher 36 fits on the surface of the V-groove of the roller while the compression amount of the pressure spring rod 355 remains unchanged, so that the polisher 36 can polish the roller with a constant pressure, ensuring the polishing effect of the polisher 36 on the V-groove of the roller, preventing the V-groove of the roller from being worn due to excessive pressure. After polishing is completed, the electric push rod 353 is controlled to drive the square block 354 to return to the initial position, and the electric telescopic rod 374 is controlled to drive the slide plate 373 to return to the initial position, so that the polisher 36 and the probe 376 return to the initial position.

[0045] See also Figure 1 , Figure 3-Figure 6 The scraping unit 4 includes a square spring rod 41 hinged on the rear side of the upper end of the integrated plate 34, the upper end of the square spring rod 41 is arranged to be tilted forward, and a pressing spring rod 42 is hinged to the opposite side of the square spring rod 41 and the integrated plate 34, and the lower end of the pressing spring rod 42 is arranged to be tilted forward. A fitting mechanism 43 for fitting to the surface of the roller is detachably installed on the upper end of the square spring rod 41, and two impact mechanisms 44 are symmetrically arranged on the left and right below the square spring rod 41. When the square spring rod 41 rotates downward, the impact mechanism 44 can continuously impact the square spring rod 41.

[0046] The scraping unit 4 is used to scrape off the hard particles on the surface of the roller; specifically, firstly, the corresponding fitting mechanism 43 is selected according to the size of the V-groove of the roller and installed on the upper end of the square spring rod 41. After the roller is clamped and fixed, the fitting mechanism 43 can always fit on the surface of the roller and compress the square spring rod 41. When there are hard particles on the surface of the roller, the roller drives the hard particles on the surface to rotate clockwise to the corresponding position of the fitting mechanism 43 first. Under the action of the square spring rod 41, the fitting mechanism 43 can be pressed against the bottom of the hard particles on the surface of the roller. When the roller continues to rotate, the hard particles on the surface of the roller drive the square spring rod 41 to rotate with the hinge between it and the integrated plate 34 as the reference through the fitting mechanism 43, and under the action of the pressing spring rod 42, the fitting mechanism 43 has a certain scraping force on the hard particles, so that the fitting mechanism 43 can scrape off the hard particles on the surface of the roller. At the same time, the impact mechanism 44 can continuously impact the square spring rod 41 to further ensure that the hard particles on the surface of the roller are scraped off.

[0048] It should be noted that the elastic force of the square spring rod 41 is much greater than the elastic force of the extension spring rod 432 .

[0049] The fitting mechanism 43 is always fitted to the surface of the roller; specifically, firstly, a suitable triangular block 433 is selected according to the size of the V-groove of the roller and the connecting plate 431 is installed on the square spring rod 41. After the roller is clamped and fixed, the surface of the roller can compress the triangular block 433 so that the surface of the connecting plate 431 fits the surface of the roller. When the square spring rod 41 moves to the corresponding position of the V-groove of the roller, the triangular block 433 fits in the V-groove under the action of the top spring rod 432, so that the triangular block 433 can scrape off the hard particles in the V-groove.

An inclined rod 412 with a front end tilted downward is installed on the circular plate 411, and the lower end of the inclined rod 412 is in contact with the active member 445.

The position of the round rod 449 at the lower end of the integrated plate 34 corresponding to the lower end of the integrated plate 34 is fixedly installed with an L-shaped lifting rod 341. The front end of the horizontal section of the lifting rod 341 is set as an inclined surface, and the lifting rod 341 is used to drive the round rod 449 to move upward.

[0053] It should be noted that the active component 445 in the present invention includes an electric slider assembly and a switch assembly, wherein the switch assembly is used to start and close the electric slider assembly, and the electric slider assembly includes a slide rail and an electric slider, wherein the slide rail is fixedly mounted on the integrated board 34, the electric slider and the slide rail are slidably connected, and the electric slider and the matching spring rod 446 are fixedly connected, wherein initially the inclined rod 412 is attached to the switch assembly, and at this time the electric slider assembly is in a closed state, when the square spring rod 41 rotates, the square spring rod 41 drives the inclined rod 412 to rotate downward through the circular plate 411, so that the inclined rod 412 can press down the switch assembly to put the electric slider in an open state, thereby enabling the electric slider to drive the matching spring rod 446 to move back and forth, and when the inclined rod 412 returns to its initial position, the switch assembly can close the electric slider assembly.

[0054] The impact mechanism 44 is used to continuously impact the square spring rod 41; specifically, when the square spring rod 41 rotates, the square spring rod 41 can press down the impact spring rod 444, so that the impact spring rod 444 cooperates with the matching rod 443 through the inclined groove 442, drives the matching plate 441 to move backward, and the matching plate 441 drives the transmission rod 447 to move backward. At the same time, the square spring rod 41 drives the inclined rod 412 through the circular plate 411 to trigger the active member 445, so that the active member 445 drives the matching spring rod 446 to move back and forth. And when the matching spring rod 446 moves forward, the matching spring rod 446 will not cooperate with the matching hole 448 to drive the transmission rod 447 to move forward due to the action of its inclined surface. When the matching spring rod 446 moves to the front limit position and starts to move backward, the matching spring rod 446 can be inserted into the corresponding matching hole 448 and drive the transmission rod 447 to move backward, so that the transmission rod 447 drives the matching plate 441 to move backward, and the impact spring rod 444 is compressed downward under the cooperation of the inclined groove 442 and the matching rod 443.

[0055] When the matching spring rod 446 moves to the corresponding position of the lifting rod 341, the telescopic end of the matching spring rod 446 moves out of the matching hole 448 under the cooperation of the round rod 449 and the lifting rod 341, so that the impact spring rod 444 impacts the square spring rod 41, and as the rotation angle of the square spring rod 41 becomes larger and larger, the impact spring rod 444 is compressed more and more under the action of the square spring rod 41. At the same time, each time the matching spring rod 446 moves to the front limit position and starts to move backward, The mating spring rods 446 can be inserted into the mating holes 448 corresponding to their positions and drive the transmission rod 447 to move backward, so that the impact spring rod 444 moves downward relative to the square spring rod 41. When the mating spring rod 446 moves to the corresponding position of the lifting rod 341, the impact force of the impact spring rod 444 on the square spring rod 41 will increase with the increase of the rotation angle of the square spring rod 41, thereby making the impact force of the square spring rod 41 on the hard particles greater and greater, ensuring that the hard particles on the surface of the roller can be completely scraped off.

[0056] See also Figure 1 , Figure 3-Figure 5 The cleaning unit 5 includes a vertical plate 51 which is installed on the front side of the upper end of the slide seat 31 for sliding forward and backward. The upper end of the vertical plate 51 slides forward and backward and penetrates the integrated plate 34. A cleaning piece 53 is installed on the upper rear end of the vertical plate 51 through a guide rod 52 with a plurality of elastic telescopic structures. Two synchronous pieces 54 arranged symmetrically on the left and right are connected between the vertical plate 51 and the matching block 371.

[0057] It should be noted that the cleaning member 53 in the present invention includes a U-shaped seat and a cleaning wheel, wherein the U-shaped seat and the guide rod 52 are fixedly connected, the cleaning wheel is rotatably installed in the U-shaped seat, and the U-shaped seat drives the cleaning wheel to rotate, and bristles are arranged on the surface of the cleaning wheel, so that the cleaning wheel can thoroughly clean the roller.

[0058] It should be noted that the synchronizer 54 in the present invention includes a driven rod fixedly installed on the left and right ends of the L-shaped structure of the vertical plate 51, and the synchronizer 54 also includes a synchronization rod fixedly installed on the left and right ends of the L-shaped structure of the matching block 371. The opposite sides of the driven rod and the synchronization rod are both set to teeth and are meshed with gears, and the gears and the slide seat 31 are rotatably connected. When the matching block 371 moves, the matching block 371 can drive the vertical plate 51 to move synchronously in the direction opposite to the moving direction of the matching block 371 through the driven rod, the gear and the synchronization rod.

[0059] When the matching block 371 moves forward so that the probe 376 is in contact with the surface of the roller, the matching block 371 drives the vertical plate 51 to move backward synchronously through the synchronous member 54, so that the vertical plate 51 drives the cleaning member 53 to be in contact with the surface of the roller through the guide rod 52, and the cleaning member 53 is started to clean the surface of the roller. When the probe 376 moves to the corresponding position of the V-groove of the roller and is always in contact with the surface of the V-groove of the roller, the matching block 371 drives the vertical plate 51 to move toward the direction close to the roller through the synchronous member 54, thereby causing the cleaning member 53 to clean the V-groove of the roller, so that the cleaning member 53 can thoroughly clean the surface of the roller, thereby increasing the polishing efficiency of the roller.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
