Description

Technical Field

[0001] This utility model relates to the technical field of hexagonal steel columns, and in particular to a grinding and polishing equipment for hexagonal steel columns. Background Technology

[0002] Hexagonal steel columns are steel components with a hexagonal cross-section. They are a type of polygonal steel widely used in construction, machinery manufacturing, bridge construction, and other engineering structures. The characteristics of hexagonal steel columns are their six equal sides and six equal interior angles, each of which is 120 degrees. This geometry gives hexagonal steel columns high structural stability and strength when subjected to axial and bending loads. Therefore, there is a particular need for hexagonal steel column grinding and polishing equipment.

[0003] In the existing process of grinding hexagonal steel columns, since all six sides of the column need to be ground, the column is easily obstructed when flipping it over to grind different sides due to the inconsistent height. This can prevent the column from turning smoothly. Furthermore, if the grinding stone is set too high, the contact between the grinding stone and the hexagonal steel column will not be tight, which may result in uneven grinding. This not only affects the grinding quality and appearance of the product, but may also reduce production efficiency, increase operational difficulty and defect rate, and adversely affect the smooth operation of the production process. Utility Model Content

[0004] The purpose of this invention is to provide a grinding and polishing equipment for hexagonal steel columns, to solve the problems mentioned in the background art. In the grinding process of existing hexagonal steel columns, due to their multiple different sizes and angles, when different sides need to be ground, the hexagonal steel column must be flipped. This flipping operation may lead to inconsistent contact between the grinding stone and the hexagonal steel column during subsequent grinding, resulting in uneven surface finish, reduced dimensional accuracy, and insufficient edge and corner treatment after grinding. This leads to decreased product quality, increased rework rate, and reduced overall production efficiency. Furthermore, frequent flipping and adjustment may increase the labor intensity and operating time of operators, further affecting production progress and cost control.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5This utility model provides a technical solution: a hexagonal steel column grinding and polishing equipment, including a conveyor frame 1, a support frame 2 fixedly connected to the lower surface of the conveyor frame 1, a conveyor wheel 3 rotatably connected to one side surface of the conveyor frame 1, a stop wheel 4 fixedly connected to one side surface of the conveyor wheel 3, a conveyor belt 5 rotatably connected to the outer surface of the conveyor wheel 3, a first drive motor 6 rotatably connected to the inner surface of the conveyor belt 5, a platform 7 fixedly connected to the lower surface of the first drive motor 6, a flipping mechanism 8 provided on the lower surface of the conveyor frame 1, a grinding chamber 9 fixedly connected to the upper surface of the conveyor frame 1, a sliding mechanism 10 provided on the upper surface of the grinding chamber 9, a slider 11 slidably connected to the upper surface of the grinding chamber 9, a fixed plate 12 fixedly connected to the lower surface of the slider 11, a lifting mechanism 13 provided on the lower surface of the fixed plate 12, a rotating motor 14 fixedly connected to the surface of the lifting mechanism 13, a main shaft 15 fixedly connected to the lower surface of the rotating motor 14, and a grinding stone 16 fixedly connected to the outer surface of the main shaft 15.

[0023] The lifting mechanism 13 includes a fixed rod 1301, a T-slot 1302, a T-block 1303, a second fixed block 1304, a second threaded rod 1305, a first fixed seat 1306, a second servo motor 1307, a support block 1308, a second fixed seat 1309, a shaft 1310, a lifting rod 1311, a central shaft 1312, and a lifting plate 1313. The fixed rod 1301 is fixedly connected to the lower surface of the fixed plate 12. A T-slot 1302 is formed on the outer surface of the fixed rod 1301, and a T-shaped rod is slidably connected to the inner surface of the T-slot 1302. Block 1303, a second fixing block 1304 is fixedly connected to the lower surface of the T-block 1303, a second threaded rod 1305 is rotatably connected to the inner surface of the second fixing block 1304, a first fixing seat 1306 is rotatably connected to the outer surface of the second threaded rod 1305, a second servo motor 1307 is fixedly connected to one side surface of the second threaded rod 1305, a support block 1308 is fixedly connected to the outer surface of the second servo motor 1307, a second fixing seat 1309 is fixedly connected to the lower surface of the fixing plate 12, and a support block 1308 is fixedly connected to one side surface of the second fixing seat 1309. A shaft 1310 is fixedly connected to the outer surface of the second fixed seat 1309. A lifting rod 1311 is rotatably connected to the outer surface of the shaft 1310. A central shaft 1312 is fixedly connected to one side surface of the lifting rod 1311. A second fixed seat 1309 is fixedly connected to the lower surface of the second fixed seat 1309 via a fixed rod 1301, a T-slot 1302, a T-block 1303, a second fixed block 1304, a second threaded rod 1305, a first fixed seat 1306, a second servo motor 1307, a support block 1308, a second fixed seat 1309, a shaft 1310, a lifting rod 1311, and a central shaft 1312. The configuration of 12 and the lifting plate 1313 allows for the following operation: activating the second servo motor 1307 rotates the second threaded rod 1305, causing the second fixed block 1304 to move along the second threaded rod 1305. This causes the T-block 1303 to slide within the T-slot 1302, thereby changing the angle between the lifting rod 1311 and the fixed plate 12. The lifting rod 1311 then moves the central shaft 1312, causing the other lifting rod 1311 to change its angle with the fixed plate 12. Consequently, the lifting plate 1313 changes its height, achieving the lifting purpose.

[0024] Furthermore, two sets of fixing rods 1301 are provided on the lower surface of fixing plate 12, and two sets of first fixing seats 1306 are provided on the outer surface of second threaded rod 1305. With the fixing rods 1301 and first fixing seats 1306, the first fixing seats 1306 fix the position of the second threaded rod 1305 during use, so that the second threaded rod 1305 will not change its position when it rotates with the second servo motor 1307, thus enabling more stable lifting and lowering.

[0025] Furthermore, two sets of second fixed seats 1309 are provided on the lower surface of the fixed plate 12, and two sets of lifting rods 1311 are provided on the outer surface of the shaft 1310. With the provision of the second fixed seats 1309 and lifting rods 1311, during use, the lifting rods 1311 change the angle between themselves and the fixed plate 12, thereby changing the height of the lifting plate 1313 and thus achieving lifting.

[0026] Furthermore, the flipping mechanism 8 includes a support platform 801, a first servo motor 802, a lead screw 803, a rotating wheel 804, a connecting block 805, a connecting plate 806, a limiting groove 807, a rotating rod 808, a gear 809, a toothed plate 810, a clamping plate 811, a advancing wheel 812, a first fixing block 813, a first threaded rod 814, and a limiting block 815. The support platform 801 is fixedly connected to the lower surface of the conveyor frame 1. The first servo motor 802 is fixedly connected to one side surface of the support platform 801. The lead screw 803 is fixedly connected to one side surface of the first servo motor 802. A rotating wheel 804 meshes with the outer surface of component 03. A connecting block 805 is fixedly connected to one side surface of the rotating wheel 804. A connecting plate 806 is fixedly connected to one side surface of the connecting block 805. A limit groove 807 is formed on the outer surface of the connecting plate 806. A rotating rod 808 is fixedly connected to one side surface of the connecting plate 806. A gear 809 is rotatably connected to the outer surface of the rotating rod 808. A gear plate 810 meshes with the outer surface of the gear 809. A clamping plate 811 is fixedly connected to one side surface of the gear plate 810. A progressive wheel 812 is rotatably connected to the outer surface of the clamping plate 811. The connecting plate 806... A first fixing block 813 is fixedly connected to one side surface of the support platform 801. A first threaded rod 814 is rotatably connected to the inner surface of the first fixing block 813. A limit block 815 is fixedly connected to the inner surface of the support platform 801. Through the arrangement of the support platform 801, the first servo motor 802, the lead screw 803, the rotating wheel 804, the connecting block 805, the connecting plate 806, the limit groove 807, the rotating rod 808, the gear 809, the toothed plate 810, the clamping plate 811, the advancing wheel 812, the first fixing block 813, the first threaded rod 814, and the limit block 815, during use, the threaded rod 814 is rotated. The threaded rod 814 drives the clamping plate 811 to move. The movement of the clamping plate 811 drives the toothed plate 810 to move. The movement of the toothed plate 810 causes the gear 809 to rotate, thereby driving the toothed plate 810 on the other side to move. When the clamping plate 811 moves to the size suitable for the hexagonal steel column, the threaded rod 814 stops rotating and the servo motor 802 is started. The servo motor 802 drives the lead screw 803 to rotate. The lead screw 803 drives the rotating wheel 804 to rotate. The limiting groove 807 and the limiting block 815 limit the rotation position of the rotating wheel 804, thereby causing the entire flipping mechanism 8 to rotate, achieving the purpose of flipping the hexagonal steel column.

[0027] Furthermore, the inner wall dimension of the limiting groove 807 matches the outer wall dimension of the limiting block 815. The toothed plate 810 has two sets on the outer surface of the gear 809. Through the setting of the limiting groove 807 and the toothed plate 810, the limiting groove 807 ensures that the rotating wheel 804 and the connecting plate 806 are in the correct position during use, preventing displacement during their rotation.

[0028] Furthermore, the sliding mechanism 10 includes a rotating plate 1001, a second drive motor 1002, a rotating shaft 1003, a connecting rod 1004, a sliding plate 1005, and a sliding groove 1006. The rotating plate 1001 is rotatably connected to the upper surface of the grinding chamber 9. The second drive motor 1002 is fixedly connected to the upper surface of the rotating plate 1001. The rotating shaft 1003 is fixedly connected to the upper surface of the rotating plate 1001. The connecting rod 1004 is rotatably connected to the outer surface of the rotating shaft 1003. The sliding plate 1005 is fixedly connected to the lower surface of the rotating shaft 1003. A sliding groove 1006 is formed on the upper surface of the grinding chamber 9. The mechanism utilizes the rotating plate 1001, the second drive motor 1002, the rotating shaft 1003, the connecting rod 1004, the sliding plate 1005, and the sliding groove 1006. When the slide 1006 is in use, the second drive motor 1002 is started, which drives the rotating plate 1001 to rotate, causing the rotating shaft 1003 to rotate around the second drive motor 1002, thereby changing the position of the rotating shaft 1003. The rotating shaft 1003 drives the connecting rod 1004 to move together, and the connecting rod 1004 drives the slide plate 1005 to move along the slide 1006. When the connecting rod 1004 is blocked by the second drive motor 1002, causing the rotating plate 1001 to stop rotating, the second drive motor 1002 rotates in the opposite direction, driving the rotating plate 1001 to rotate in the opposite direction, so that the slide plate 1005 returns to its original position along the slide 1006, thereby achieving the purpose of reciprocating movement.

[0029] Furthermore, two sets of slide grooves 1006 are provided on the upper surface of the grinding chamber 9, and two sets of rotating shafts 1003 are provided on the outer surface of the connecting rod 1004. Through the arrangement of slide grooves 1006 and rotating shafts 1003, during use, slide grooves 1006 restrict the movement direction of the slide plate 1005, so that the slide plate 1005 can only run along the trajectory of slide grooves 1006, thereby enabling the slide plate 1005 to slide more efficiently.

[0030] Furthermore, multiple sets of conveyor wheels 3 are provided on one side surface of the conveyor frame 1, and two sets of sliders 11 are provided on the lower surface of the grinding chamber 9. With the arrangement of conveyor wheels 3 and sliders 11, the conveyor wheels 3 can continuously transport hexagonal steel columns during use, reducing the time and labor intensity of manual handling and greatly improving production efficiency.

[0031] Working principle: When grinding is required, the first drive motor 7 is started, which drives the conveyor belt 5 to rotate, thereby driving the conveyor wheel 3 to rotate. The conveyor wheel 3 transports the hexagonal steel column into the grinding chamber 9. The threaded rod 814 is rotated, which drives the clamping plate 811 to move. The movement of the clamping plate 811 drives the toothed plate 810 to move. The movement of the toothed plate 810 causes the gear 809 to rotate, thereby driving the toothed plate 810 on the other side to move. When the clamping plate 811 moves to the appropriate size for the hexagonal steel column, the rotation of the threaded rod 814 is stopped, and the servo motor 802 is started. The servo motor 802 drives the lead screw 803 to rotate, which drives the rotating wheel 804 to rotate. The limit groove 807 and the limit block... 815 restricts the rotation position of the rotating wheel 804, thereby causing the entire flipping mechanism 8 to rotate, achieving the purpose of flipping the hexagonal steel column. The second servo motor 1307 is activated, driving the second threaded rod 1305 to rotate, causing the second fixed block 1304 to move along the second threaded rod 1305, causing the T-block 1303 to slide in the T-slot 1302, thereby changing the angle between the lifting rod 1311 and the fixed plate 12. The lifting rod 1311 drives the central shaft 1312 to change together, thereby changing the angle between the other lifting rod 1311 and the fixed plate 12, causing the lifting plate 1313 to change its height, thus changing the height of the polishing stone 16. The rotation motor 14 is then activated. 14 drives the main shaft 15 to rotate, thereby driving the polishing stone 16 to rotate, activating the second drive motor 1002. The second drive motor 1002 drives the rotating plate 1001 to rotate, causing the rotating shaft 1003 to rotate around the second drive motor 1002, thereby changing the position of the rotating shaft 1003. The rotating shaft 1003 drives the connecting rod 1004 to move together, and the connecting rod 1004 drives the slide plate 1005 to move along the slide groove 1006. When the connecting rod 1004 is blocked by the second drive motor 1002, causing the rotating plate 1001 to stop rotating, the second drive motor 1002 rotates in the opposite direction, driving the rotating plate 1001 to rotate in the opposite direction, causing the slide plate 1005 to move along the slide groove. 1006 returns to its original position, allowing the polishing stone 16 to polish back and forth on the hexagonal steel column. This solves the problem that in the existing polishing process, since all six sides of the hexagonal steel column need to be polished, the column is easily obstructed by contact with the polishing surface when flipping it over to polish different sides due to inconsistent heights, preventing smooth flipping. In addition, if the polishing stone is set too high, the contact between the polishing stone and the hexagonal steel column will not be tight, which may lead to uneven polishing results. This not only affects the polishing quality and appearance of the product, but may also reduce production efficiency, increase the difficulty of operation and the defect rate, and adversely affect the smooth operation of the production process.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
