Description

Technical Field

[0001] The invention belongs to the technical field of I-beam processing, and particularly relates to a device for continuously flipping and milling holes at the installation hole positions of I-beams. Background Technique

[0002] Milling holes at the hole positions of I-beams means forming holes with specific positions and sizes on I-beams through milling processing. Using processing equipment such as milling machines, the I-beams are cut by milling cutters installed on the milling machines. During the processing, according to the pre-designed hole position drawings or programming instructions, the movement of the milling machine table, the rotation speed of the milling cutter, the feed rate and other parameters are precisely controlled, so that the milling cutter cuts out holes that meet the requirements on the I-beams along the specified path.

[0003] The milling processing of the installation holes of I-beams directly affects the connection accuracy of components and the stability of engineering structures. The I-beam milling hole equipment lacks integration and coordination. After milling one side of the I-beam, it needs to be transferred to an independent flipping device and then re-positioned and clamped on the milling hole equipment. This separated process operation not only increases the floor area and investment cost of the equipment, but also causes the accumulation of processing errors due to multiple clamping and positioning, reducing the processing accuracy and production efficiency. Moreover, the non-continuous operation state of the equipment makes it difficult to integrate into the automated production line and cannot meet the requirements of modern manufacturing for efficient and continuous production. Therefore, there is a need to provide a device for continuously flipping and milling holes at the installation hole positions of I-beams, which adopts an integrated processing method of automatic material transfer, positioning and clamping, and flipping, and can realize continuous milling and flipping and surface conversion processing.

[0014] A device for continuously flipping and milling holes in the installation holes of I-beams, and its method steps are as follows: Step 1: First, pass the I-beam from right to left through the inner cavity of the cage frame so that the bottom of the I-beam contacts the surface of the material transfer roller. Subsequently, the servo motor is started, and through the meshing drive of the driving chain disk and the chain, it drives a plurality of force-bearing chain disks to rotate, causing the material transfer roller to rotate. During the rotation of the material transfer roller, it drives the I-beam to move to the left, so that the I-beam reaches above the milling hole processing table and enters the working area of the milling machine. Subsequently, the second oil cylinder is opened to push the lifting plate, causing the lifting plate to slide in the inner cavity of the lifting frame.

Subsequently, the servo motor is started again, and by driving the material transfer roller to rotate, the I-beam is continuously conveyed to the drilling position. Step 3: After the single-sided punching of the I-beam is completed, the four first oil cylinders are started simultaneously, and the two lifting frames are pushed towards each other, causing the side beam to move and driving the material conveying rollers to rise and fall. As a result, the upper and lower material conveying rollers are respectively clamped on the top and bottom of the I-beam, centrally clamping and positioning the I-beam. Then, the stepping motor is started and drives the reducer to operate. During the operation of the reducer, the driving gear is driven to rotate. During the rotation of the driving gear, the transmission gear meshing with it is driven to rotate. During the rotation of the transmission gear, the force-bearing gear meshing with it is driven to rotate, so that the active material turning disc rotates in the inner cavity of the cage. During the rotation of the active material turning disc, the driven material turning disc is driven to rotate simultaneously through the support arm, so that the I-beam can be flipped by 180 degrees.

[0024] A device for continuously flipping and milling holes in the installation holes of I-beams, and its method steps are as follows: Step 1: First, pass the I-beam through the inner cavity of the cage 1 from right to left, making the bottom of the I-beam contact the surface of the material conveying roller 55. Subsequently, the servo motor 57 is started, and through the meshing drive of the driving chain disc 58 and the chain, it drives a plurality of force-bearing chain discs 56 to rotate, causing the material conveying roller 55 to rotate. During the rotation of the material conveying roller 55, it drives the I-beam to move to the left, enabling the I-beam to reach above the milling hole processing table 2 and enter the working area of the milling machine 3. Subsequently, the second oil cylinder 62 is opened to push the lifting plate 61, causing the lifting plate 61 to slide within the inner cavity of the lifting frame 52. During the lifting process of the lifting plate 61, it squeezes the clamping plate 63. At the same time, due to the oblique guiding action of the arc-shaped chute 66 and the limiting rod 65, the clamping plates 63 on the same horizontal plane slide towards each other during the lifting process and contact the front and rear sides of the I-beam, thereby clamping and fixing the I-beam. Step 2: At the same time, the hydraulic lifting table 7 located at the top of the milling hole processing table 2 rises and contacts the bottom of the I-beam. Subsequently, the milling machine 3 is started to drill the I-beam. After drilling at a single position is completed, the second oil cylinder 62 contracts, driving the lifting plate 61 and the clamping plate 63 to reset. At the same time, under the guiding action of the limiting rod 65 and the arc-shaped chute 66, the clamping plate 63 releases the clamping of the I-beam and resets. Subsequently, the servo motor 57 is started again, driving the material conveying roller 55 to rotate, continuously conveying the I-beam to the drilling position. Step 3: After the single-sided drilling of the I-beam is completed, the four first oil cylinders 53 are started simultaneously to push the two lifting frames 52 towards each other, causing the side beam 54 to move and driving the material conveying roller 55 to lift. As a result, the upper and lower material conveying rollers 55 respectively clamp the top and bottom of the I-beam, centrally clamping and positioning the I-beam. Then, the stepping motor 43 is started to drive the reducer 44 to operate. During the operation of the reducer 44, it drives the driving gear 46 to rotate. During the rotation of the driving gear 46, it drives the driven transmission gear 47 meshing with it to rotate. During the rotation of the transmission gear 47, it drives the force-bearing gear 48 meshing with it to rotate, thereby causing the active material turning disc 41 to rotate within the inner cavity of the cage 1. During the rotation of the active material turning disc 41, it drives the driven material turning disc 42 to rotate simultaneously through the support arm 51, enabling the I-beam to be flipped by 180 degrees. After the flipping, the first oil cylinder 53 retracts and resets, enabling the lifting frame 52 and the material conveying roller 55 to both reset. With the coordinated use of the milling hole processing table 2 and the milling machine 3, milling hole operations are performed on the other side of the I-beam.

[0025] In summary, for the device for continuously flipping and milling holes in the installation holes of I-beams, through the setting of the lifting and conveying assembly 5, the I-beams are horizontally conveyed.

Subsequently, the milling hole machine (3) is started to drill the I-beam. After drilling at a single position is completed, the second oil cylinder (62) contracts, driving the lifting plate (61) and the clamping plate (63) to reset. Meanwhile, under the guiding action of the limiting rod (65) and the arc-shaped chute (66), the clamping plate (63) releases the clamping of the I-beam and resets. Subsequently, the servo motor (57) is turned on again, and the feeding roller (55) is driven to rotate, continuously conveying the I-beam to the drilling position; Step 3: After the single-sided drilling of the I-beam is completed, the four first oil cylinders (53) are started simultaneously, and the two lifting frames (52) are pushed towards each other, causing the side beam (54) to move and driving the feeding roller (55) to move up and down. As a result, the upper and lower feeding rollers (55) respectively clamp the top and bottom of the I-beam, centrally clamping and positioning the I-beam. Then, the stepping motor (43) is started and drives the reducer (44) to operate. During the operation of the reducer (44), the driving gear (46) is driven to rotate. During the rotation of the driving gear (46), the transmission gear (47) meshing with it is driven to rotate. During the rotation of the transmission gear (47), the force-bearing gear (48) meshing with it is driven to rotate, thereby causing the active material transfer disk (41) to rotate in the inner cavity of the cage (1). During the rotation of the active material transfer disk (41), the driven material transfer disk (42) is simultaneously driven to rotate through the support arm (51), enabling the I-beam to be flipped by 180 degrees. After the flip, the first oil cylinder (53) retracts and resets, causing the lifting frame (52) and the feeding roller (55) to both reset. With the coordinated use of the milling hole processing table (2) and the milling hole machine (3), milling hole operation is performed on the other side of the I-beam.
