Description

Technical Field

[0001] This utility model relates to the field of H-beam processing technology, and in particular to a positioning drilling device for welded H-beams. Background Technology

[0002] H-beams are a widely used type of profile, especially in various buildings. When using H-beams, holes are sometimes drilled for easier bolt connections. This not only makes the structure of the H-beams more stable but also more aesthetically pleasing. During the drilling process, it is important to ensure that the holes are not crooked, otherwise it will affect normal use and may even cause the H-beams to be scrapped.

[0003] However, existing handheld drilling devices are prone to tilting and movement due to operational factors, resulting in tilted drilling and reduced hole accuracy, which is detrimental to the normal use of H-beams. Furthermore, the H-beams are easily displaced during drilling, making them impractical. Therefore, there is an urgent need for a welding H-beam positioning drilling device to solve these problems. Utility Model Content

A connecting rod is rotatably connected to the top of the first roller. A second roller is rotatably connected to the top of each of the two connecting rods. A movable plate is provided at the end of each mounting plate near the baffle plate. A clamping plate is fixed to the side of the two movable plates that are close to each other. By moving the first roller in the inclined and horizontal grooves, the second roller can be driven to press one side of the movable plate, and the clamping plate can be driven to fix and clamp the two sides of the H-shaped steel beam.

[0008] Preferably, the sides of the baffle plate and the mounting plate that are close to each other are provided with mounting grooves, and the baffle plate has two mounting grooves at one end. The inner walls of the mounting grooves are fixed with first fixing rods on both sides, and the outer walls of the first fixing rods are slidably provided with first sliders. The sides of the two first sliders that are close to each other are respectively fixedly connected to the two ends of the moving plate. One end of a spring is fixed to one side of each of the multiple first sliders, and the other end of the spring is fixed to one side of the inner wall of the mounting groove. The top of one of the moving plates is provided with an indicator mechanism for confirming the drilling position. When the second roller moves away from the moving plate, the spring can drive the moving plate to reset and disengage from the clamping of the H-beam.

[0010] Preferably, a threaded hole is provided on one side of the second slider, and a suitable fastening screw is provided inside the threaded hole.

[0011] Preferably, the drilling mechanism includes electric slide rails mounted on both sides of the top of the base plate. Each of the two electric slide rails has a matching third slider on its outer wall. The top of each of the two third sliders is fixed to the same mounting bracket. An electric cylinder is mounted on the top of the mounting bracket. A fixed bracket is fixed to the bottom of the output shaft of the electric cylinder. Lead screws are rotatably connected to both sides of the inner wall of the fixed bracket. A matching sliding block with a sliding sleeve is provided on the outer wall of the lead screw. A breathable protective cover is fixed to the bottom of the sliding block. A second motor is installed inside the breathable protective cover. The output shaft of the second motor is fixedly connected to the top of the drill rod via a coupling. A first motor is mounted at one end of the fixed bracket. The output shaft of the first motor is fixedly connected to one end of the lead screw. Second fixed rods are fixed at both ends of both sides of the inner wall of the fixed bracket.

The other ends of the two plug rods are fixed to the outer walls of the two connecting rods respectively. When the third slider moves through the sleeve rod and the plug rod, both sides of the H-shaped steel beam can be fixed at the same time.

[0013] Preferably, a connecting plate is fixed to one bottom end of the fixing frame, an infrared sensor is provided at one bottom end of the connecting plate, and a receiver is provided at the top of the fixing block.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Due to the adoption of a fixed mechanism, when the mounting frame moves, it drives the connecting rod to move via the sleeve rod and the insertion rod. The connecting rod then drives the first roller and the second roller to move. The second roller gradually squeezes and pushes one side of the moving plate. When the first roller moves into the transverse groove, the two clamping plates completely clamp and fix both sides of the H-beam. This achieves the effect of clamping and fixing the H-beam during the drilling process. Through the linkage of the mounting frame and the connecting rod, the cost of fixing the H-beam using a separate drive device is saved, achieving energy saving and environmental protection, and increasing the stability of the H-beam during the drilling process.

[0016] 2. By employing a receiver and infrared sensor, the drilling position for the H-beam is determined through a fixed block, pointer, and scale lines. Then, through the cooperation of the receiver and infrared sensor, the drill rod can be precisely moved to the accurate drilling position, thereby achieving accuracy and precision in drilling, reducing errors caused by human factors, improving the reliability and consistency of the operation, ensuring that the position and size of each hole meet the design requirements, and reducing material waste.

[0032] Working principle: In use, first place the H-beam 4 on top of the fixing plate 201, then align one end of the H-beam 4 with one end of the abutment plate 2, and straighten the H-beam 4. Then, by moving the fixing block 505, the fixing block 505 will drive the second slider 503 to slide in the slide groove 502. The fixing block 505 will also drive the pointer 508 to move together, and the pointer 508 will move above the scale line 506. Move the pointer 508 to the appropriate scale line 506, and then drill a precise hole in the H-beam 4. Then, the fastening screw 504 engages with the threaded hole and limits the second slider 503. Finally, the controller controls the two... The two electric slide rails 6 operate synchronously. The two electric slide rails 6 drive the third slider 601 to move. The third slider 601 drives the mounting bracket 3 to move. When the third slider 601 moves, it drives the sleeve rod 602 to move, and then drives the insertion rod 603 to move. Then it drives the connecting rod 206 to move. The connecting rod 206 first drives the first roller 205 to slide in the inclined groove 204, and drives the insertion rod 603 to slide and extend inside the sleeve rod 602. During the movement, the connecting rod 206 drives the second roller 207 to move. The second roller 207 gradually pushes the moving plate 5. When the first roller 205 moves into the transverse groove 203, the moving plate 5 drives the two clamping plates 5. 01. The H-beam 4 is clamped and fixed on both sides. The mounting bracket 3 will move the fixing bracket 302 and the connecting plate 509. When the connecting plate 509 moves the infrared sensor 510 above the receiver 507, the infrared sensor 510 will transmit a signal to the controller. The controller will shut down the operation of the electric slide rail 6. At this time, the third slider 601 will stop precisely at a certain position on the electric slide rail 6. Then the controller will turn on the second motor 309. The second motor 309 will drive the drill rod 310 to rotate and rotate at high speed. Then the controller will start the electric cylinder 301, which will push the fixing bracket 302. As the fixed frame 302 moves downward, it will drive the drill rod 310 downward and approach the H-beam 4 to perform drilling operations. Through simple programming of the controller, the first motor 307 will drive the lead screw 304 to rotate in a fixed position, and drive the sliding block 305 with the sliding sleeve to move to the same position each time to achieve equidistant drilling, which is convenient for subsequent installation. After the drilling operation is completed, the controller will reset the third slider 601. At this time, the first roller 205 will drive the second roller 207 away from the moving plate 5. Then the spring 211 will drive the two moving plates 5 to reset and move away from the clamping of the H-beam 4. Then the workers can remove the H-beam 4.
