Description

Technical Field

[0001] This utility model relates to the field of steel structure production technology, and in particular to a grinding equipment for steel structure production. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They have advantages such as high strength, light weight, good overall rigidity, and strong resistance to deformation. During the production process, steel materials will have burrs left after welding or cutting, which need to be ground using edge grinding equipment.

[0028] Please see Figure 1-8This utility model provides a steel structure edge grinding device, including a casing 1. A wastewater tank 11 is provided on the upper side wall of the casing 1. Wastewater generated when the cooling mechanism 6 cools the grinding wheel 510 flows into the wastewater tank 11. First sliding grooves 2 are provided on both the front and rear side walls of the wastewater tank 11. Two first sliding blocks 21 are slidably arranged in the first sliding grooves 2. A bidirectional screw 22 is rotatably arranged between the two side walls of one of the first sliding grooves 2. One end of the bidirectional screw 22 extends to the outside of the casing 1 and is fixedly connected to a first handwheel 23. Two handwheels 23 are symmetrically distributed along the transverse axis of the wastewater tank 11. Each of the first sliders 21 has a connecting rod 3 fixedly connected to one side wall that is close to each other. The other ends of the two connecting rods 3 are fixedly connected to a moving platform 31. Rotating the first handwheel 23 can drive the bidirectional screw 22 to rotate. When the bidirectional screw 22 rotates, it can bring the two first sliders 21 that are meshed with it closer to each other. Under the drive of the connecting rod 3, the two moving platforms 31 will move closer to each other, so that the two U-shaped positioning frames 43 can clamp the steel. The moving platform 31 is provided with a positioning mechanism 4. The upper side wall of the casing 1 is provided with a grinding mechanism 5. The rear outer wall of the casing 1 is provided with a cooling mechanism 6.

[0029] Specifically, such as Figure 3 and Figure 4As shown, a steel structure production edge grinding device includes a positioning mechanism 4 comprising a vertical plate 41, a rotating shaft 42, a U-shaped positioning frame 43, an internally threaded tube 44, a lifting screw 45, a second handwheel 46, a pressure plate 47, a drive block 48, a follower plate 49, a transfer rod 410, a third handwheel 411, a limit rod 412, and a limit hole 413. A vertical plate 41 is fixedly connected to the upper side wall of a moving table 31. A rotating shaft 42 is rotatably inserted into the vertical plate 41. U-shaped positioning frames 43 are fixedly connected to the ends of two rotating shafts 42 that are close to each other. A U-shaped positioning frame 43 is embedded in the upper side wall of the U-shaped positioning frame 43. An internally threaded pipe 44 is internally threaded and connected to a lifting screw 45. A second handwheel 46 is fixedly connected to the upper end of the lifting screw 45, and a pressure plate 47 is rotatably mounted on its lower end. A drive block 48 is fixedly connected to the other end of one of the rotating shafts 42. A follower plate 49 is slidably mounted on the drive block 48. Two symmetrically distributed adapter rods 410 are fixedly connected to the side wall of the follower plate 49 away from the vertical plate 41. A third handwheel 411 is fixedly connected to the other end of each adapter rod 410. Two symmetrically distributed limit rods are fixedly connected to the side wall of the follower plate 49 closer to the vertical plate 41. 412. Two limiting holes 413 adapted to the limiting rod 412 are opened on the side wall of the upright plate 41 near the limiting rod 412. Turning the second handwheel 46 can drive the lifting screw 45 to rotate. When the lifting screw 45 rotates, under the action of the internal thread tube 44, it will push the pressure plate 47 to move downward, pressing the steel and positioning the steel. After one side of the steel is ground, pull the third handwheel 411 outward. Under the drive of the adapter rod 410, the follower plate 49 moves outward together, so that the limiting rod 412 disengages from the limiting hole 413. Then turn the third handwheel 412. 11. Driven by the adapter rod 410, the follower plate 49 rotates together, which in turn drives the rotating shaft 42 to rotate through the drive block 48. This causes the rotating shaft 42 to rotate the U-shaped positioning frame 43. Driven by the steel, the U-shaped positioning frame 43 on the other side rotates together, turning the steel 180 degrees so that its other side faces the grinding wheel 510. Then, push the third handwheel 411 to move inward, so that the limit rod 412 is inserted into the limit hole 413, fixing the U-shaped positioning frame 43. This completes the rotation of the steel without having to release the limit on the steel, making it more convenient.

[0030] Specifically, such as Figure 2 and Figure 6As shown, a steel structure production edge grinding device includes an edge grinding mechanism 5 comprising a second slide groove 51, a drive motor 52, a screw 53, a second slider 54, a moving plate 55, a mounting plate 56, an electric push rod 57, a movable plate 58, a grinding motor 59, and a grinding wheel 510. The second slide groove 51 is provided at the rear of the upper side wall of the housing 1. The second slider 54 is slidably disposed within the second slide groove 51. The drive motor 52 is mounted on one side wall of the housing 1. The output shaft of the drive motor 52 extends into the second slide groove 51 and is fixedly connected to the screw 53. The other end of the screw 53 is threaded through the second slider 54 and rotatably connected to the other side wall of the second slide groove 51. The moving plate 55 is fixedly connected to the upper side wall of the second slider 54, and the moving plate 55 is fixedly connected to the upper side wall of the moving plate 55. There is a mounting plate 56, and an electric actuator 57 is mounted on the rear side wall of the mounting plate 56. The output shaft of the electric actuator 57 passes through the mounting plate 56 and is fixedly connected to a movable plate 58. A grinding motor 59 is mounted on the front side wall of the movable plate 58. A grinding wheel 510 is fixedly connected to the output shaft end of the grinding motor 59. The output shaft of the electric actuator 57 can push the movable plate 58 forward, so that the grinding wheel 510 contacts the side of the steel. The output shaft of the grinding motor 59 can drive the grinding wheel 510 to rotate, grinding the edge of the steel. The output shaft of the drive motor 52 can drive the screw 53 to rotate. When the screw 53 rotates, it can cause the second slider 54, which is threaded with it, to move the movable plate 55, thereby moving the grinding wheel 510 to fully grind the side of the steel.

[0031] Specifically, such as Figure 7 As shown, a steel structure edge grinding device includes a cooling mechanism 6 comprising a water tank 61, an L-shaped bracket 62, a nozzle 63, and a water pump 64. The water tank 61 is fixedly connected to the rear outer wall of the casing 1, and the L-shaped bracket 62 is fixedly connected to the upper side wall of the movable plate 58. The nozzle 63 is mounted on the L-shaped bracket 62, and the water pump 64 is mounted on the upper outer wall of the water tank 61. The inlet of the water pump 64 is connected to the water tank 61 via a flexible water pipe, and the outlet is connected to the nozzle 63 via a flexible water pipe. During the grinding process, the water pump 64 draws water from the water tank 61 and delivers it to the nozzle 63. The nozzle 63 sprays water onto the grinding wheel 510 to cool the grinding wheel 510, thereby reducing the working temperature of the grinding wheel 510, reducing wear, and extending the service life of the grinding wheel 510.

[0032] Specifically, such as Figure 5 As shown, a steel structure production edge grinding equipment has two symmetrically distributed guide grooves 431 on the inner wall of the U-shaped positioning frame 43 near the rotating shaft 42. The pressure plate 47 slides with the guide grooves 431, so that the pressure plate 47 can only move in a straight line and will not rotate with the lifting screw 45.

[0033] Specifically, such as Figure 6As shown, a steel structure production edge grinding equipment has guide rods 561 slidably inserted on the mounting plate 56 and on both sides of the electric push rod 57. The front end of the guide rod 561 is fixedly connected to the movable plate 58. The guide rod 561 can support and guide the movable plate 58 to make it more stable.

[0034] Specifically, such as Figure 8 As shown, a steel structure production edge grinding equipment has a sewage pipe 111 installed on the bottom wall of the sewage tank 11, and the sewage generated after cooling is discharged through the sewage pipe 111.

[0035] It should be noted that this utility model is a steel structure production edge grinding device. In use, the steel is placed on two U-shaped positioning frames 43. Then, the first handwheel 23 is rotated to drive the bidirectional screw 22 to rotate. When the bidirectional screw 22 rotates, it causes the two first sliders 21 meshing with it to move closer together. Under the drive of the connecting rod 3, the two moving tables 31 will move closer together, causing the two U-shaped positioning frames 43 to clamp the steel. Then, the second handwheel 46 is rotated to drive the lifting screw 45 to rotate. When the lifting screw 45 rotates, it engages with the internal threaded tube 44... Under the action of [unclear], the pressure plate 47 will be pushed downward to press the steel tightly. Then, the electric actuator 57 will be activated, and the output shaft of the electric actuator 57 will push the movable plate 58 forward, so that the grinding wheel 510 contacts the side of the steel. Then, the grinding motor 59 will be activated, and the output shaft of the grinding motor 59 will drive the grinding wheel 510 to rotate, grinding the edge of the steel. Then, the output shaft of the drive motor 52 will drive the screw 53 to rotate. When the screw 53 rotates, it can cause the second slider 54, which is threaded with it, to move the movable plate 55, thereby driving the grinding wheel 510 to move. The sides of the steel are thoroughly ground. During the grinding process, water pump 64 draws water from water tank 61 and delivers it to nozzle 63. Nozzle 63 sprays water onto grinding wheel 510 to cool it down, reducing its operating temperature, wear, and extending its service life. After one side is ground, the third handwheel 411 is pulled outward. Driven by adapter rod 410, follower plate 49 moves outward, causing limit rod 412 to disengage from limit hole 413. Then, the third handwheel 411 is rotated. Driven by the adapter rod 410, the wheel 411 rotates together with the moving plate 49, which in turn drives the rotating shaft 42 to rotate through the drive block 48. This causes the rotating shaft 42 to rotate the U-shaped positioning frame 43. Driven by the steel, the U-shaped positioning frame 43 on the other side rotates together, turning the steel 180 degrees so that its other side faces the grinding wheel 510. Then, the third handwheel 411 is pushed inward so that the limiting rod 412 is inserted into the limiting hole 413, fixing the U-shaped positioning frame 43. This completes the rotation of the steel, and then the edge can be ground.
