Description

Technical Field

[0001] This invention relates to the field of H-beam steel product processing technology, and particularly to an automatic reversible grinding line suitable for H-beam steel products. Background Technology

[0002] H-beams are widely used in construction, bridges, machinery manufacturing, and many other fields. During the production and processing of H-beams, after cutting processes such as ion cutting and flame cutting, oxide scale, burrs, weld slag, and other impurities often remain near the welding position. These impurities can affect the quality of subsequent welding processes. Therefore, it is necessary to set up grinding equipment before welding to precisely grind the surface of the H-beams to ensure welding quality and overall product precision.

[0003] To achieve comprehensive grinding of both sides of H-beams, existing H-beam grinding equipment typically includes a tilting mechanism. This mechanism flips the workpiece, allowing for grinding of both sides without manual intervention, thus improving efficiency to some extent. However, the tilting mechanism in existing grinding equipment is located in the workpiece's groove, which is part of the grinding environment. During grinding, a large amount of debris, dust, and other foreign matter accumulates within the groove. With prolonged operation, this accumulation leads to friction and pressure between the debris adhering to the groove wall and the workpiece surface when the workpiece is inserted, potentially causing wear, scratches, and other defects that negatively impact the surface quality of the H-beam.

[0004] Therefore, an automated reversible grinding line suitable for H-beam products is provided to address the above issues. Summary of the Invention

[0015] Preferably, a pressure plate for pushing the first plunger is fixed at the connection between the gas spring and the hydraulic telescopic rod.

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0017] The positive and progressive effects of this invention are as follows: The aforementioned automatic reversible grinding line for H-beam products features a scraper and a matching drive mechanism installed in the side groove of the turning mechanism. After grinding, the drive mechanism moves the scraper along the side groove, pushing and scraping away accumulated grinding debris, dust, and other foreign objects, fundamentally solving the problem of foreign object accumulation in the groove of existing turning mechanisms. This avoids friction or compression from debris adhering to the groove wall when the workpiece enters the side groove, effectively reducing the probability of wear, scratches, and other defects on the workpiece surface, and ensuring the surface precision and processing quality of the H-beam products.

[0018] The scraper's drive mechanism does not require a separate additional power source; its power comes from the rotation of the rotating base of the material-turning mechanism itself. When the base rotates, the rollers in the drive mechanism pass over the protrusions. The pushing action of the protrusions on the rollers drives the internal components of the drive mechanism to move, thereby driving the scraper to translate.

[0019] The protrusion is equipped with a lifting mechanism. When the scraper needs to be driven for side groove cleaning, the lifting mechanism raises the protrusion into the bottom shell of the tilting mechanism, allowing the rollers to contact the protrusion and obtain power when the round seat rotates. When the scraper is not needed (such as during workpiece tilting), the lifting mechanism lowers the protrusion away from the bottom shell, the rollers do not contact the protrusion, and the driving mechanism does not operate, avoiding interference with the workpiece tilting operation. Simultaneously, the lifting mechanism requires no additional power; the movement of the tilting mechanism is driven by the second linear module, and the side seat blocks and pushes the pressure bar, thus driving the lifting mechanism to automatically raise and lower the protrusion, improving the level of automation.

[0020] By setting up an air supply mechanism and a blower housing, the surface of the scraper can be cleaned by blowing air. The power of the air supply mechanism also comes from the movement of the equipment itself, without the need for an additional power source. During the stretching process of the gas spring, the pressure plate pushes the first plug of the air supply mechanism, which drives the air supply mechanism to output clean air. This air is then blown onto the scraper through the blower housing, removing debris, dust and other foreign objects attached to the side wall of the scraper, ensuring the cleanliness of the scraper surface. This measure prevents foreign objects attached to the scraper surface from affecting the cleaning effect of the side groove. Attached Figure Description

[0023] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0024] like Figures 1-15 As shown, a reversible grinding automatic line suitable for H-beam products includes a processing chamber 1 and a conveyor line 2 passing through the processing chamber 1.

[0025] The processing chamber 1 is equipped with a robot 4 and a material turning mechanism 5. The robot 4 and the material turning mechanism 5 are located on both sides of the conveyor line 2, and the end of the robot 4 is equipped with a grinding part 8 and an identification scanner 9.

[0026] The robot 4 has a first linear module 3 at its bottom, which is parallel to the conveyor line 2; the flipping mechanism 5 has a second linear module 7 at its bottom, which is perpendicular to the conveyor line 2.

[0027] The material turning mechanism 5 includes a circular seat 502 and a power unit for driving the circular seat 502 to rotate. A side groove 506 is provided on one side of the circular seat 502.

[0028] A scraper 10 is provided in the side groove 506, and the scraper 10 is connected to a drive mechanism 13. The drive mechanism 13 is used to drive the scraper 10 to move horizontally along the side groove 506.

[0029] like Figure 2 As shown, the conveyor line 2 includes a feeding roller conveyor 201, a grinding roller conveyor 203, and a discharging roller conveyor 202. The feeding roller conveyor 201 and the discharging roller conveyor 202 are respectively located on both sides of the processing chamber 1. The grinding roller conveyor 203 is located inside the processing chamber 1 and is configured in multiple sections, i.e., it is composed of multiple sub-roller conveyors. A trough 204 is provided between each pair of adjacent sub-roller conveyors.

[0030] During grinding, the workpiece is conveyed by the feeding roller conveyor 201 and enters the grinding roller conveyor 203. The robot 4 scans the workpiece through the recognition scanner 9. During the scanning process, the first linear module 3 drives the robot 4 to move along the length of the workpiece to achieve scanning at various points along the length. The grinding path of the robot 4 is automatically generated based on the scanning data. Then, the robot 4, in conjunction with the first linear module 3, drives the grinding part 8 to move to various points on the top of the workpiece to grind the top.

[0031] After the top is polished, the second linear module 7 drives the flipping mechanism 5 to move towards the slot 204, allowing the workpiece to enter the side slot 506. Then, the power unit drives the round base 502 to rotate 180°, completing the flipping of the workpiece in the side slot 506. After flipping, the second linear module 7 drives the flipping mechanism 5 to move closer to the robot 4, causing the flipping mechanism 5 to leave the slot 204, avoiding obstruction of subsequent polishing and scanning operations. By repeating the above scanning and polishing process, the top of the workpiece is polished after flipping. After polishing, the second linear module 7 drives the flipping mechanism 5 back to the slot 204, and the workpiece enters the side slot 506. Then, the power unit drives the round base 502 to reset and rotate 180°, resetting the workpiece. Finally, the second linear module 7 drives the flipping mechanism 5 away from the robot 4 to leave the slot 204, restoring it to its original position. Figure 2 The state.

[0032] The above scheme enables the workpiece to be automatically flipped so that the grinding of its top and bottom can be completed automatically. After grinding, the grinding roller conveyor 203 feeds the workpiece into the discharge roller conveyor 202 so that the workpiece is transported away.

[0033] Furthermore, a scraper 10 is provided inside the side groove 506. During grinding, the scraper 10 is located inside the side groove 506. After grinding, the scraper 10 is moved by the drive mechanism 13 to move from inside the side groove 506 to outside the side groove 506, pushing and scraping out foreign objects and debris inside the side groove 506. This prevents the debris and dust generated during grinding from accumulating inside the side groove 506, reducing the friction or squeezing caused by debris attached to the side groove 506 wall when the workpiece enters the side groove 506, thereby reducing the wear and scratches on the workpiece.

[0034] Both sides of the grinding roller conveyor 203 are provided with carrier blocks 6. Each carrier block 6 is equipped with a clamping part, specifically using a cylinder to drive the pressure block to clamp and hold the workpiece.

[0035] The recognition scanner 9 uses a 3D camera to scan and photograph the workpiece. The grinding unit 8 consists of a third motor 801 and a grinding head 802 mounted on the output shaft of the third motor 801. The third motor 801 drives the grinding head 802 to rotate, and the grinding head 802 contacts the workpiece to achieve grinding.

[0036] like Figure 4 , Figure 5 , Figure 7 as well as Figure 8 As shown, the material turning mechanism 5 also includes a bottom shell 501, and the circular seat 502 is rotatably connected to the bottom shell 501; the power unit includes a first motor 505 fixedly installed on the outer wall of the bottom shell 501, the output shaft of the first motor 505 is fixed with a gear 507, the gear 507 meshes with an arc-shaped rack 504, an arc-shaped groove 503 is opened on the cylindrical surface of the circular seat 502, and the arc-shaped rack 504 is fixed in the arc-shaped groove 503.

[0037] The first motor 505 drives the gear 507 to rotate. Through the meshing transmission between the gear 507 and the arc rack 504, the round seat 502 rotates about the bottom shell 501, which is used to flip the workpiece.

[0038] like Figures 9-12As shown, the driving mechanism 13 is disposed within the circular seat 502; the driving mechanism 13 includes a second cylindrical body 1304 fixed within the circular seat 502; a third piston 1306 is fitted inside the second cylindrical body 1304, a second plunger 1307 is fixed to the bottom of the third piston 1306, and the top surface of the third piston 1306 is elastically connected to the inner wall of the top of the second cylindrical body 1304 through a third helical spring 1305; the second plunger 1307 extends into the arc-shaped groove 503, and the second plunger 1307... 7. A roller 1308 is rotatably installed at one end of the cylinder 1304 that extends into the arc groove 503. The top end of the second cylinder 1304 is connected to a hydraulic telescopic rod 1302 through a second connecting pipe 1301. The hydraulic telescopic rod 1302 is fixedly installed in the round seat 502. The end of the hydraulic telescopic rod 1302 is connected to the side wall of the scraper 10 through a gas spring 1303. The bottom inner side of the bottom shell 501 is provided with a protrusion 1405 for the roller 1308 to travel on, and the protrusion 1405 is connected to a lifting mechanism 14.

[0039] The protrusion 1405 is an isosceles triangular block structure, and the top of the protrusion 1405 is provided with rounded corners.

[0040] like Figures 4-5 as well as Figures 9-12 As shown, the second linear module 7 includes a movable seat 706 fixed to the bottom of the base shell 501 and a translation part for driving the movable seat 706 to move. The movable seat 706 has an inner groove 7061, which communicates with the base shell 501. The lifting mechanism 14 is installed in the inner groove 7061. The inner groove 7061 provides installation space for the lifting mechanism 14.

[0041] The translation part includes a base 701, a guide post 704 is fixed on the base 701, and a stud 705 is rotatably mounted on the base 701. One end of the stud 705 is connected to a second motor 703. The movable seat 706 is threadedly connected to the stud 705, and the movable seat 706 is slidably sleeved with the guide post 704.

[0042] The working principle of the second linear module 7 is as follows: the second motor 703 drives the stud 705 to rotate, the stud 705 and the movable seat 706 are driven by threads, and the guide post 704 provides sliding guidance for the movable seat 706, so that the movable seat 706 and the structure above the movable seat 706 move together.

[0043] like Figure 10 and Figure 12As shown, the lifting mechanism 14 includes a first wedge block 1401 and a second wedge block 1406; the top of the first wedge block 1401 is provided with a first inclined surface, and the bottom of the second wedge block 1406 is provided with a second inclined surface, the second inclined surface is in contact with the first inclined surface, a bottom strip 1403 is fixed to the bottom of the first wedge block 1401, one side of the bottom strip 1403 is elastically connected to one side wall of the inner groove 7061 through a fourth helical spring 1404, a pressure strip 1402 is fixed to one side of the first wedge block 1401, the pressure strip 1402 is slidably engaged with a guide hole provided on one side of the movable seat 706, and the guide hole is connected to the inner groove 7061, the top of the second wedge block 1406 is fixed with a protrusion 1405, and the protrusion 1405 is slidably installed in the inner groove 7061 in a vertical direction.

[0044] The second linear module 7 has a side seat 702 on one side, and the side seat 702 is located on one side of the pressure strip 1402.

[0045] When the workpiece is flipped, the flipping mechanism 5 moves into the slot 204, the pressure bar 1402 and the side seat 702 are not in contact, and the two are in a separated state. The lifting mechanism 14 and the protrusion 1405 are as follows: Figure 10 As shown, when the protrusion 1405 is in a low position, during the rotation of the rotating base 502 driven by the material turning mechanism 5, the roller 1308 does not contact the protrusion 1405 and is not squeezed or pushed by the protrusion 1405, so the driving mechanism 13 will not drive the scraper 10 to move.

[0046] After the workpiece is ground, the flipping mechanism 5 is reset to its original position. Figure 2 During the process shown, the pressure bar 1402 moves closer to the side seat 702, where it is blocked and pushed by the side seat 702, causing the pressure bar 1402 to move into the inner groove 7061. Simultaneously, the pressure bar 1402 moves the first wedge block 1401 and the bottom bar 1403 together, compressing the fourth helical spring 1404. At the same time, the first wedge block 1401 pushes the second inclined surface of the second wedge block 1406 through the first inclined surface, causing the second wedge block 1406 to move the protrusion 1405 upwards. The protrusion 1405 moves into the bottom shell 501, as shown. Figure 12 As shown.

[0047] The subsequent drive seat 502 reciprocates in both directions, causing the roller 1308 to move back and forth on both sides of the protrusion 1405. As the roller 1308 moves from the side of the protrusion 1405 towards the center (i.e., the chamfer) of the protrusion 1405, it is pushed by the protrusion 1405, causing the second piston 1307 to drive the third piston 1306 to move upward within the second cylinder 1304. The third piston 1306 pushes the hydraulic medium within the second cylinder 1304, causing it to enter the hydraulic telescopic rod 1302 through the second connecting pipe 1301. This causes the hydraulic telescopic rod 1302 to drive the gas spring 1303 and the scraper 10 to move outward from the side groove 506. During this process, the third piston 1306 compresses the third helical spring 1305. As the wheel 1308 moves from the center of the protrusion 1405 to the side of the protrusion 1405, the third piston 1306, the second plunger 1307, and the roller 1308 are reset by the elastic force of the third helical spring 1305. The second cylinder 1304 draws the hydraulic medium in the hydraulic telescopic rod 1302 through the second connecting pipe 1301. The hydraulic telescopic rod 1302 retracts as a whole, thereby driving the air spring 1303 and the scraper 10 to move towards the inside of the side groove 506. After the scraper 10 is in contact with the inner wall of the side groove 506, the hydraulic telescopic rod 1302 continues to retract, causing the air spring 1303 to stretch. The elastic force of the stretched air spring 1303 acts on the scraper 10, causing the scraper 10 to press against the inner wall of the side groove 506.

[0048] In practice, a sealing gasket is provided on the side wall of the scraper 10. The elastic force of the gas spring 1303 is used to press the sealing gasket on the scraper 10 against the inner side wall of the side groove 506, so as to ensure the sealing of the groove body opened on the inner side wall of the side groove 506.

[0049] When the workpiece is ground again and flipped over, the flipping mechanism 5 is moved away from the side seat 702, the pressure bar 1402 is separated from the side seat 702, the pressure bar 1402 loses its pushing force, and the first wedge block 1401, the pressure bar 1402 and the bottom bar 1403 are reset and moved together by the elastic force of the fourth helical spring 1404. The first wedge block 1401 abuts against the side wall of the inner groove 7061, while the second wedge block 1406 and the protrusion 1405 are reset and fall by gravity. The second inclined surface remains attached to the first inclined surface, and the protrusion 1405 leaves the bottom shell 501.

[0050] like Figures 5-6 As shown, a blower shell 11 is provided on one side of the circular seat 502. The blower shell 11 is provided with a strip-shaped air outlet, and the air outlet faces the inner side of the side groove 506. The blower shell 11 is connected to an air supply mechanism 12.

[0051] like Figure 11 , Figure 13 as well as Figure 14As shown, the inner side of the side groove 506 is provided with a mounting groove 5021, and the air supply mechanism 12 is installed in the mounting groove 5021. The air supply mechanism 12 includes a first cylinder 1201 fixedly installed in the mounting groove 5021. A first piston 1206 is fitted inside the first cylinder 1201. One side of the first piston 1206 is elastically connected to the inner sidewall of the first cylinder 1201 by a first helical spring 1208, and a first plug 12 is fixed to the other side of the first piston 1206. 07, and the first plunger 1207 extends out of the first cylinder 1201. A first one-way valve 1202 and a second one-way valve 1203 are installed on one side of the first cylinder 1201. The first one-way valve 1202 is connected to an air outlet pipe 1204. The air outlet pipe 1204 is connected to a first connecting pipe 1210 through a telescopic pipe 1211. The first connecting pipe 1210 is fixedly connected to the blower shell 11. The second one-way valve 1203 is connected to a filter 1209 through an air inlet pipe 1205.

[0052] like Figure 15 As shown, a second piston 1212 is fixedly sleeved at one end of the telescopic tube 1211, and the second piston 1212 is fitted into the air outlet tube 1204. A second helical spring 1213 is provided inside the air outlet tube 1204.

[0053] like Figure 14 As shown, a pressure plate 15 for pushing the first plunger 1207 is fixed at the connection between the gas spring 1303 and the hydraulic telescopic rod 1302.

[0054] The above design allows for air blowing to clean the sides of the scraper 10, removing foreign matter attached to it and ensuring the cleanliness of the scraper 10 surface.

[0055] After the scraper 10 is made to fit against the inner wall of the side groove 506, the pressure plate 15 fits against the first plunger 1207, and the side of the scraper 10 is aligned with the air outlet. During the subsequent stretching of the gas spring 1303, the pressure plate 15 pushes the first plunger 1207, causing the first plunger 1207 to move into the first cylinder 1201. The first plunger 1207 drives the first piston 1206 to move within the first cylinder 1201, pushing the gas in the first cylinder 1201 and compressing the first helical spring 1208. The gas then enters the air blower housing 11 through the air outlet 1204, the telescopic pipe 1211, and the first connecting pipe 1210, and finally blows out from the air outlet to clean the side wall of the scraper 10.

[0056] During the process of moving the scraper 10 to the outside of the side groove 506, the hydraulic telescopic rod 1302 extends. First, the gas spring 1303 returns to its original position and retracts. The gas spring 1303 drives the pressure plate 15 to return to its original position. The pressure plate 15 separates from the first plug 1207. The first piston 1206 and the first plug 1207 are returned to their original positions by the elastic force of the first helical spring 1208. After being filtered by the filter 1209, the outside air enters the first cylinder 1201 through the air inlet pipe 1205 and the second one-way valve 1203 to replenish clean gas.

[0057] Through the above design, automatic cleaning of the surface of scraper 10 is achieved, while the air supply mechanism 12 provides power by pushing through the pressure plate 15, and the air blowing cleaning does not require the setting of an additional power source and control components.

[0058] With the telescopic tube 1211 in place, when the side groove 506 is not in the workpiece and the cleaning scraper 10 is being cleaned, the telescopic tube 1211 extends out of the air outlet 1204 by the elastic force of the second helical spring 1213, and the blower shell 11 extends out from one side of the scraper 10, ensuring that the blower on it is aligned with the side wall of the scraper 10.

[0059] When the workpiece is flipped, the workpiece enters the side groove 506 and fits against the scraper 10. The workpiece pushes the blower shell 11, causing the telescopic tube 1211 to move into the air outlet 1204 and compress the second helical spring 1213. Through the above-mentioned retractable and movable design, it will not hinder the workpiece from fitting against the scraper 10.

[0060] This invention is not limited to the embodiments described above. Any changes made to their shape or structure fall within the protection scope of this invention. The protection scope of this invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications fall within the protection scope of this invention.
