Description

Technical Field

[0001] The present invention relates to the technical field of processing platforms, and in particular to a processing platform for a pipe pile end plate and a processing method thereof. Background Art

[0002] The end plates of pipe piles are divided into flange plates and flange plates. Flange plates are often installed at both ends of pipe piles and are used to connect pipe piles with bolts. When producing steel flange plates, burrs are easily present on the surface of the flange plates, so they need to be polished using a polishing platform to ensure the sealing and consistency of the flange plates when they are connected.

[0003] When a flange is polished using a polishing platform in the prior art, the flange needs to be fixed by a fixture first, and then the flange is polished with the aid of the polishing platform. After polishing, the flange is removed from the fixture.

[0004] The above and prior art have the following defects: in the process of polishing the inner and outer arc surfaces of the flange, the polishing platform needs to polish the inner and outer arc surfaces of the flange in sequence, so the polishing efficiency of the flange is low, reducing the practicality of the polishing platform.

[0005] Therefore, a processing platform for a pipe pile end plate and a processing method thereof are proposed. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the polishing platform needs to polish the inner and outer arc surfaces of the flange in sequence, so the polishing efficiency of the flange is low, and to propose a processing platform for a pipe pile end plate and a processing method thereof.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a processing platform for a pipe pile end plate and a processing method thereof, comprising a processing platform and a flange, a mounting frame is fixedly connected to the upper surface of the processing platform, a chip collecting groove is provided on the surface of the processing platform, and further comprising:

[0008] A polishing structure is arranged on the surface of the mounting frame, and is used to polish the inner and outer arc surfaces of the flange at the same time. The polishing structure includes a first electric push rod fixedly mounted on the upper surface of the mounting frame, two polishing rods for polishing the flange, a first pulley and a second pulley and a synchronous belt for driving the polishing rods to rotate, and a rotating plate for supporting the first pulley;

[0009] A limiting structure provided on the upper surface of the processing table and used to align the flange with the polishing rod, wherein the limiting structure includes a support plate fixedly mounted on the upper surface of the processing table and a bending rod used to limit the flange;

[0010] A tensioning structure is arranged on the surface of the rotating plate and is used to adjust the tightness of the synchronous belt. The tensioning structure includes a fixing frame fixedly mounted on the surface of the rotating plate, a third pulley for squeezing the synchronous belt, and a spring for adjusting the pressure between the third pulley and the synchronous belt.

[0011] The effect achieved by the above-mentioned components is as follows: by setting the polishing structure, when polishing the flange, the two polishing rods will respectively press against the inner arc surface and the outer arc surface of the flange, so that the inner arc surface and the outer arc surface of the flange can be polished at the same time, thereby greatly improving the polishing efficiency and practicality of the polishing platform; by setting the limiting structure, before polishing the flange, the output ends of the two second electric push rods can be controlled to adjust the position of the flange in the horizontal direction according to the size of the flange, to ensure that the two subsequent polishing rods can press against the flange normally; by setting the tensioning structure, during the operation of the synchronous belt, the third pulley will squeeze the synchronous belt, thereby preventing the synchronous belt from loosening and failing to transmit normally; at the same time, by adjusting the elastic force of the spring, it can also ensure that appropriate pressure is maintained between the third pulley and the synchronous belt.

[0012] Preferably, the output end of the first electric push rod vertically passes through the mounting frame and is fixedly equipped with a connecting disk, the lower surface of the connecting disk is rotatably connected to a worm gear, the lower end of the worm gear is fixedly connected to a rotating plate, the lower surface of the connecting disk is fixedly connected to a servo motor, the output end of the servo motor is horizontally and coaxially fixedly equipped with a worm, the worm gear is meshed with the worm gear, the first pulley is rotatably connected to the rotating plate, the polishing rod is coaxially and detachably mounted on the lower end of the first pulley, the surface of the rotating plate is fixedly connected to a driving motor, the output end of the driving motor is coaxially and fixedly connected to an impeller, the second pulley is fixedly sleeved on the outer circumferential surface of the impeller, the synchronous belt is sleeved on the tooth surfaces of the first pulley and the second pulley and meshed with them, and the two polishing rods are respectively against the inner arc surface and the outer arc surface of the flange.

[0014] Preferably, the lead angle of the worm is smaller than the equivalent friction angle between the worm and the worm wheel.

[0015] The effect achieved by the above components is: since the lead angle of the worm is smaller than the equivalent friction angle between the worm and the worm wheel, after the servo motor is turned off, self-locking will be achieved between the worm and the worm wheel, that is, the worm wheel cannot drive the worm to rotate, thereby limiting the position of the two polishing rods and ensuring that the polishing rods are stably against the surface of the flange.

[0016] Preferably, a rotating plate is rotatably connected to the surface of the mounting frame, a strip plate is rotatably connected to the upper surface of the connecting plate, and the rotating plate is rotatably connected to the strip plate.

[0017] The effect achieved by the above components is: the rotating plate will pull the strip plate, the strip plate will drive the rotating plate to rotate, and the cooperation between the rotating plate and the strip plate can prevent the force generated during polishing from damaging the output end of the first electric push rod.

[0018] Preferably, a second electric push rod is horizontally fixedly installed on the surface of the support plate, an output end of the second electric push rod passes through the support plate and is fixedly installed with an extension plate, the bending rod is fixedly installed on the surface of the extension plate, a prism is horizontally slidably penetrated in the support plate, and the prism is fixedly connected to the extension plate.

[0019] The effect achieved by the above components is: before polishing the flange, the output ends of the two second electric push rods are controlled to extend, so that the two extension plates will move towards each other, and the extension plates will drive the prisms to slide along the support plates. When the bending rod follows the extension plates to move to a suitable position, the flange is prevented. Then, the output ends of the second electric push rods are controlled to contract, and the extension plates will drive the bending rods to slide, thereby limiting the position of the flange.

[0020] Preferably, the bending rod is formed by splicing a horizontal section and an upper folding section, the circumferential surface of the horizontal section of the bending rod is rotatably connected to a first roller, and the circumferential surface of the upper folding section of the bending rod is rotatably connected to a second roller, and the circumferential surfaces of the first roller and the second roller both rest against the surface of the flange.

[0021] The effect achieved by the above-mentioned components is: after the flange is placed on the arc surface of the first roller on the bending rod, the horizontal section of the bending rod can support the first roller to keep the flange in a horizontal state; after the second roller at the upper folding section of the bending rod is against the surface of the flange, the upper folding section of the bending rod can further limit the position of the flange to prevent the flange from moving upward during the polishing process.

[0022] Preferably, a slide plate is slidably connected to the inner wall of the fixed frame, the slide plate is rotatably connected to the third pulley, the third pulley is meshed with the synchronous belt, a screw rod is threadedly connected to the inner thread of the fixed frame, one end of the screw rod is rotatably connected to a pressure plate, the two ends of the spring are respectively fixedly connected to the pressure plate and the slide plate, one end of the screw rod is fixedly equipped with a hexagonal plate, the arc surface of the screw rod is slidably sleeved with a rotating frame, and the size of the rotating frame is adapted to the size of the hexagonal plate.

[0023] The effect achieved by the above components is: during the operation of the synchronous belt, the slide plate will use the elastic force of the spring to make the third pulley press against the inner tooth surface of the synchronous belt, and the third pulley will squeeze the synchronous belt, thereby preventing the synchronous belt from loosening and failing to transmit normally. When it is necessary to adjust the pressure of the third pulley on the synchronous belt, the rotating frame is slid along the arc surface of the screw to engage the rotating frame with the hexagonal plate, and then the rotating frame is rotated. The hexagonal plate will drive the screw to rotate as the rotating frame rotates, and the screw will drive the pressure plate to move with the help of the thread. When the pressure plate moves toward the slide plate, the compressed length of the spring becomes longer. At this time, the elastic force of the spring becomes greater, and the pressure between the third pulley and the synchronous belt will also become greater. When the pressure plate moves away from the slide plate, the compressed length of the spring becomes shorter. At this time, the elastic force of the spring becomes smaller, and the pressure between the third pulley and the synchronous belt will also become smaller, thereby ensuring that appropriate pressure is maintained between the third pulley and the synchronous belt.

[0024] Preferably, a propeller is coaxially fixedly mounted on the lower end of the third pulley.

[0025] The effects achieved by the above components are: the synchronous belt will drive the third pulley to rotate during operation, the third pulley will drive the propeller to rotate, the propeller will blow the air downward, thereby further improving the cleaning effect of debris attached to the surface of the flange, and avoiding the situation where residual debris hinders the polishing effect.

[0026] Preferably, the outer wall of the fixed frame is rotatably connected with a rotating rod, and the arc surface of the rotating rod abuts against the smooth surface of the synchronous belt.

[0027] The effect achieved by the above components is that the rotating rod can guide the synchronous belt to prevent the synchronous belt from being squeezed and the contact area with the first pulley or the second pulley is reduced, thereby preventing the synchronous belt from failing to work normally.

[0028] A method for processing a pipe pile end plate comprises the following steps:

[0029] S1, controlling the output end of the first electric push rod to extend and adjust the position of the bending rod;

[0030] S2, after the flange is placed, the output end of the first electric push rod is controlled to retract to limit the position of the flange;

[0031] S3, adjusting the position of the polishing rod along the vertical direction by means of the first electric push rod;

[0032] S4, using a servo motor to drive the worm and worm wheel to make the polishing rod contact the surface of the flange;

[0033] S5. Adjust the elastic force of the spring according to the tightness of the synchronous belt, and squeeze the synchronous belt with the help of the third pulley;

[0034] S6. Turn on the drive motor to rotate the polishing rod to polish the flange.

[0035] Compared with the prior art, the advantages and positive effects of the present invention are:

[0036] 1. In the present invention, by providing a polishing structure, when polishing the flange, two polishing rods will respectively abut against the inner arc surface and the outer arc surface of the flange, so that the inner arc surface and the outer arc surface of the flange can be polished at the same time, thereby greatly improving the polishing efficiency and practicality of the polishing platform.

[0037] 2. In the present invention, by setting a limit structure, before polishing the flange, the output ends of the two second electric push rods can be controlled to telescope in the horizontal direction to adjust the position of the flange according to the size of the flange, ensuring that the subsequent two polishing rods can normally resist the flange.

[0038] 3. In the present invention, by setting a tensioning structure, the third pulley will squeeze the synchronous belt during the operation of the synchronous belt, thereby preventing the synchronous belt from being loose and unable to transmit normally. At the same time, by adjusting the elastic force of the spring, it can also ensure that the appropriate pressure is maintained between the third pulley and the synchronous belt.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0052] A polishing structure 5 is provided on the surface of the mounting frame 2 and is used to polish the inner and outer arc surfaces of the flange 4 at the same time. The polishing structure 5 includes a first electric push rod 501 fixedly mounted on the upper surface of the mounting frame 2, two polishing rods 508 for polishing the flange 4, a first pulley 507 and a second pulley 511 and a synchronous belt 512 for driving the polishing rods 508 to rotate, and a rotating plate 504 for supporting the first pulley 507;

[0053] A limiting structure 6 disposed on the upper surface of the processing table 1 for aligning the flange 4 with the polishing rod 508, the limiting structure 6 comprising a support plate 61 fixedly mounted on the upper surface of the processing table 1 and a bending rod 64 for limiting the flange 4;

[0054] A tensioning structure 7 is arranged on the surface of the rotating plate 504 and is used to adjust the tightness of the synchronous belt 512. The tensioning structure 7 includes a fixed frame 701 fixedly installed on the surface of the rotating plate 504, a third pulley 703 for squeezing the synchronous belt 512, and a spring 706 for adjusting the pressure between the third pulley 703 and the synchronous belt 512.

[0055] The specific arrangement and functions of the polishing structure 5, the limiting structure 6 and the tensioning structure 7 are described in detail below.

[0056] like Figure 2-Figure 5As shown, the output end of the first electric push rod 501 vertically passes through the mounting frame 2 and is fixedly equipped with a connecting disk 502, the lower surface of the connecting disk 502 is rotatably connected to a worm gear 503, the lower end of the worm gear 503 is fixedly connected to a rotating plate 504, the lower surface of the connecting disk 502 is fixedly connected to a servo motor 505, the output end of the servo motor 505 is horizontally and coaxially fixedly equipped with a worm 506, the worm 506 is meshed with the worm gear 503, the first pulley 507 is rotatably connected to the rotating plate 504, the polishing rod 508 is coaxially detachably installed at the lower end of the first pulley 507, the surface of the rotating plate 504 is fixedly connected to a driving motor 509, the output end of the driving motor 509 is coaxially fixedly connected to an impeller 510, and the second pulley 511 is fixedly sleeved On the outer circumference of the impeller 510, the synchronous belt 512 is sleeved on the tooth surfaces of the first pulley 507 and the second pulley 511 and meshes with them. The two polishing rods 508 are respectively against the inner arc surface and the outer arc surface of the flange 4 to control the extension of the output end of the first electric push rod 501. The connecting plate 502 follows the output end of the first electric push rod 501 to drive the worm gear 503 to move downward. The rotating plate 504 follows the worm gear 503 to drive the first pulley 507 to move. The first pulley 507 drives the polishing rod 508 to move. When the polishing rod 508 moves to a suitable position, the output end of the servo motor 505 is controlled to rotate. The rotation of the output end of the servo motor 505 drives the worm 506 to rotate. The rotation of the worm 506 drives the worm wheel 503 to rotate. 03 will drive the rotating plate 504 to rotate, and finally drive the two polishing rods 508 to move, so that the two polishing rods 508 are respectively against the inner arc surface and the outer arc surface of the flange 4, and then the driving motor 509 is turned on. The rotation of the output end of the driving motor 509 will drive the impeller 510 to rotate, and the impeller 510 will drive the second pulley 511 to rotate, and the synchronous belt 512 will drive the first pulley 507 to rotate, and the first pulley 507 will drive the polishing rods 508 to rotate. The two polishing rods 508 will polish the inner arc surface and the outer arc surface of the flange 4 at the same time, thereby greatly improving the polishing efficiency. The lead angle of the worm 506 is smaller than the equivalent friction angle between the worm 506 and the worm wheel 503. Since the lead angle of the worm 506 is smaller than the worm 50 6 and the equivalent friction angle between the worm gear 503. Therefore, after the servo motor 505 is turned off, the worm 506 and the worm gear 503 will achieve self-locking, that is, the worm gear 503 cannot drive the worm 506 to rotate, thereby achieving the purpose of limiting the positions of the two polishing rods 508 and ensuring that the polishing rods 508 are stably against the surface of the flange 4. The surface of the mounting frame 2 is rotatably connected with a rotating plate 513, and the upper surface of the connecting plate 502 is rotatably connected with a strip plate 514. The rotating plate 513 is rotatably connected with the strip plate 514. The rotating plate 513 will pull the strip plate 514, and the strip plate 514 will drive the rotating plate 513 to rotate. The cooperation between the rotating plate 513 and the strip plate 514 can avoid the situation where the force generated during polishing damages the output end of the first electric push rod 501.

[0057] like Figure 6 and Figure 7 As shown, the surface of the support plate 61 is horizontally fixedly equipped with a second electric push rod 62, the output end of the second electric push rod 62 passes through the support plate 61 and is fixedly equipped with an extension plate 63, the bending rod 64 is fixedly assembled on the surface of the extension plate 63, and a prism 67 is horizontally slidably penetrated in the support plate 61, and the prism 67 is fixedly connected to the extension plate 63. Before polishing the flange 4, the output ends of the two second electric push rods 62 are controlled to extend, so that the two extension plates 63 will move toward each other, and the extension plate 63 will drive the prism 67 to slide along the support plate 61. When the bending rod 64 follows the extension plate 63 to move to a suitable position to prevent the flange 4, the output end of the second electric push rod 62 is controlled to shrink, and the extension plate 63 will drive the bending rod 64 to slide. Thereby limiting the position of the flange 4, the bending rod 64 is formed by splicing a horizontal section and an upper folding section, the circumferential surface of the horizontal section of the bending rod 64 is rotatably connected to the first roller 65, and the circumferential surface of the upper folding section of the bending rod 64 is rotatably connected to the second roller 66, the circumferential surfaces of the first roller 65 and the second roller 66 both abut against the surface of the flange 4, after the flange 4 is placed on the arc surface of the first roller 65 on the bending rod 64, the horizontal section of the bending rod 64 can support the first roller 65 to keep the flange 4 in a horizontal state, after the second roller 66 at the upper folding section of the bending rod 64 abuts against the surface of the flange 4, the upper folding section of the bending rod 64 can further limit the position of the flange 4 to prevent the flange 4 from moving upward during the polishing process.

[0058] like Figure 8 and Fig. 9As shown, the inner wall of the fixed frame 701 is slidably connected with a slide plate 702, the slide plate 702 is rotatably connected with the third pulley 703, the third pulley 703 is meshed with the synchronous belt 512, the fixed frame 701 is internally threaded with a screw 704, one end of the screw 704 is rotatably connected with a pressure plate 705, the two ends of the spring 706 are respectively fixedly connected with the pressure plate 705 and the slide plate 702, one end of the screw 704 is fixedly equipped with a hexagonal plate 708, the circular arc surface of the screw 704 is slidably sleeved with a rotating frame 709, the size of the rotating frame 709 is adapted to the size of the hexagonal plate 708, and during the operation of the synchronous belt 512, the sliding The plate 702 will use the elastic force of the spring 706 to make the third pulley 703 press against the inner tooth surface of the synchronous belt 512, and the third pulley 703 will squeeze the synchronous belt 512, so as to prevent the synchronous belt 512 from being loose and unable to transmit normally. When it is necessary to adjust the pressure of the third pulley 703 on the synchronous belt 512, the rotating frame 709 is slid along the arc surface of the screw 704 to make the rotating frame 709 engage with the hexagonal plate 708, and then the rotating frame 709 is rotated. The hexagonal plate 708 rotates with the rotating frame 709 to drive the screw 704 to rotate, and the screw 704 will drive the pressure plate 705 to move with the help of the thread. When the pressure plate 705 moves to When the plate 705 moves in the direction close to the slide plate 702, the compressed length of the spring 706 becomes longer, at this time the elastic force of the spring 706 becomes larger, and the pressure between the third pulley 703 and the synchronous belt 512 also becomes larger. When the pressure plate 705 moves in the direction away from the slide plate 702, the compressed length of the spring 706 becomes shorter, at this time the elastic force of the spring 706 becomes smaller, and the pressure between the third pulley 703 and the synchronous belt 512 also becomes smaller, thereby ensuring that the third pulley 703 and the synchronous belt 512 maintain a suitable pressure. The lower end of the third pulley 703 is coaxially fixed with a propeller 707, and the synchronous belt 512 is in the working process. The third pulley 703 will be driven to rotate, and the third pulley 703 will be driven to rotate the propeller 707, and the propeller 707 will blow the air downward, so as to further improve the cleaning effect of the debris attached to the surface of the flange 4, and can also avoid the situation where the debris residue hinders the polishing effect. The outer wall of the fixed frame 701 is rotatably connected with a rotating rod 710, and the arc surface of the rotating rod 710 is against the smooth surface of the synchronous belt 512. The rotating rod 710 can guide the synchronous belt 512 to avoid the situation where the synchronous belt 512 cannot work normally due to the reduction of the contact area with the first pulley 507 or the second pulley 511 after being squeezed.

[0059] like Figure 1-Figure 9 As shown, a method for processing a pipe pile end plate comprises the following steps:

[0060] S1, controlling the output end of the first electric push rod 501 to extend and adjust the position of the bending rod 64;

[0061] S2, after the flange 4 is placed, the output end of the first electric push rod 501 is controlled to contract to limit the position of the flange 4;

[0062] S3, adjusting the position of the polishing rod 508 along the vertical direction by means of the first electric push rod 501;

[0063] S4, using the servo motor 505 to drive the worm 506 and the worm wheel 503 to make the polishing rod 508 contact the surface of the flange 4;

[0064] S5, adjusting the elastic force of the spring 706 according to the tightness of the synchronous belt 512, and squeezing the synchronous belt 512 with the help of the third pulley 703;

[0065] S6, turning on the driving motor 509 to rotate the polishing rod 508 to polish the flange 4.

[0066] The overall working principle is that before polishing the flange 4, the output ends of the two second electric push rods 62 are controlled to extend, so that the two extension plates 63 will move in a direction close to each other, and the extension plates 63 will drive the prism 67 to slide along the support plate 61. When the bending rod 64 follows the extension plate 63 to move to a suitable position, the flange 4 is placed on the arc surface of the first roller 65 on the bending rod 64. At this time, the horizontal section of the bending rod 64 can support the first roller 65, thereby keeping the flange 4 in a horizontal state. Then, the output end of the second electric push rod 62 is controlled to contract, and the extension plate 63 will drive the bending rod 64 to slide. At this time, the second roller 66 at the upper folding section of the bending rod 64 will abut against the surface of the flange 4. At this time, the upper folding section of the bending rod 64 can further limit the position of the flange 4 to prevent the flange 4 from moving upward during the polishing process. Then, according to the size of the flange 4, the output ends of the two second electric push rods 62 are controlled to telescope and adjust the position of the flange 4 in the horizontal direction to ensure that the subsequent two polishing rods 508 can normally abut against the flange 4.

[0067] After limiting the position of the flange 4, the output end of the first electric push rod 501 is controlled to extend, and the connecting plate 502 follows the output end of the first electric push rod 501 to drive the worm gear 503 to move downward. At this time, the rotating plate 513 will pull the strip plate 514, and the strip plate 514 will drive the rotating plate 513 to rotate. The cooperation between the rotating plate 513 and the strip plate 514 can avoid the situation that the force generated during polishing damages the output end of the first electric push rod 501. The rotating plate 504 follows the worm gear 503 to drive the first pulley 507 to move, and the first pulley 507 drives the polishing rod 508 to move. When the polishing rod 508 moves After moving to a suitable position, the output end of the servo motor 505 is controlled to rotate. The rotation of the output end of the servo motor 505 will drive the worm 506 to rotate. The rotation of the worm 506 will drive the worm wheel 503 to rotate. The worm wheel 503 will drive the rotating plate 504 to rotate, and finally drive the two polishing rods 508 to move, so that the two polishing rods 508 are respectively against the inner arc surface and the outer arc surface of the flange 4. Since the lead angle of the worm 506 is smaller than the equivalent friction angle between the worm 506 and the worm wheel 503, after the servo motor 505 is turned off, the worm 506 and the worm wheel 503 will be self-locking, that is, the worm wheel 503 The worm 506 cannot be driven to rotate, thereby limiting the position of the two polishing rods 508 and ensuring that the polishing rods 508 are stably against the surface of the flange 4. Then, the drive motor 509 is turned on, and the rotation of the output end of the drive motor 509 will drive the impeller 510 to rotate, and the impeller 510 will drive the second pulley 511 to rotate, and the synchronous belt 512 will drive the first pulley 507 to rotate, and the first pulley 507 will drive the polishing rods 508 to rotate. The two polishing rods 508 will polish the inner and outer arc surfaces of the flange 4 respectively at the same time, thereby greatly improving the polishing efficiency. In this process, the impeller 51 0 rotation will accelerate the downward flow of air, thereby blowing away the debris attached to the surface of the flange 4, making it convenient for the subsequent processing of the flange 4 such as painting. At the same time, under the transmission of the synchronous belt 512, the rotation speed and direction of the two polishing rods 508 are the same, but due to the different sizes of the inner diameter and the outer diameter of the flange 4, the flange 4 will rotate due to the different torques during the polishing process, so that the flange 4 can be fully polished. At this time, the first roller 65 and the second roller 66 can convert the sliding friction between the flange 4 and the bending rod 64 into rolling friction, thereby reducing the resistance of the flange 4 when it rotates.

[0068] When the synchronous belt 512 is working, the slide plate 702 will use the elastic force of the spring 706 to make the third pulley 703 press against the inner tooth surface of the synchronous belt 512, and the third pulley 703 will squeeze the synchronous belt 512, thereby preventing the synchronous belt 512 from loosening and failing to transmit normally. At the same time, the rotating rod 710 will guide the synchronous belt 512 to prevent the synchronous belt 512 from being squeezed and the contact area with the first pulley 507 or the second pulley 511 is reduced, so that it cannot work normally. When it is necessary to adjust the pressure of the third pulley 703 on the synchronous belt 512, the rotating frame 709 is slid along the arc surface of the screw rod 704 to engage the rotating frame 709 with the hexagonal plate 708, and then the rotating frame 709 is rotated. The hexagonal plate 708 rotates with the rotating frame 709 to drive the screw rod 704 to rotate, and the screw rod 704 drives the pressure plate 705 to move with the help of the thread. When the pressure plate 705 approaches When the slide plate 702 moves in the direction of the compression, the length of the spring 706 becomes longer. At this time, the elastic force of the spring 706 becomes larger, and the pressure between the third pulley 703 and the synchronous belt 512 also becomes larger. When the pressure plate 705 moves in the direction away from the slide plate 702, the length of the spring 706 becomes shorter. At this time, the elastic force of the spring 706 becomes smaller, and the pressure between the third pulley 703 and the synchronous belt 512 also becomes smaller, thereby ensuring that the third pulley 703 and the synchronous belt 512 maintain a suitable pressure. During operation, the synchronous belt 512 will drive the third pulley 703 to rotate, and the third pulley 703 will drive the propeller 707 to rotate. The propeller 707 will blow air downward, thereby further improving the cleaning effect of the debris attached to the surface of the flange 4, and can also avoid the situation where the debris residue hinders the polishing effect, and the debris will then fall into the chip collecting groove 3.
