Description

Technical Field

[0001] The present invention relates to the technical field of steel structure processing, and more particularly to a conveniently replaceable drill bit connector for steel structure processing and a use method thereof. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields.

[0003] In the processing of steel structures, drilling machines are the most commonly used. Drilling machines mainly use drill bits to process holes on steel structure workpieces, and can perform drilling, reaming, boring, countersinking and tapping on workpieces, and then perform subsequent assembly and other processing through various processed holes. Currently, the processing and production of steel structure workpieces cannot be separated from drilling equipment.

[0004] At present, when using a drilling machine to perform high-precision drilling processing on steel structure parts, the drill bit and the drilling machine equipment are generally connected and fixed by a relatively complicated method such as bolts, which is very inconvenient when replacing different drill bits and disassembling the drill bit for maintenance. The installation and replacement of the drill bit is relatively cumbersome and complicated, which greatly reduces the processing efficiency of steel structure workpieces and is not conducive to the production efficiency of the factory. Therefore, a drill bit connector for steel structure processing that is easy to replace and a method of use are proposed to solve the above problems. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a drill bit connector for steel structure processing that is easy to replace and a method of use. The present invention can achieve that when installing the connecting drill bit device on the mounting device, it is only necessary to first extend the connecting drill bit device into the through slot of the mounting box. At this time, the clamping assembly will fix the connecting column to ensure subsequent normal processing, and then the second step is to rotate the rotating rod to make the fixing rod rotate into the fixing slot, and the fixing rod is limited and blocked by the stopper. Through these two steps, the connecting drill bit device and the mounting device can be fixed, and the installation of the drill bit is simple and convenient; when disassembling or replacing the connecting drill bit device, it is only necessary to first lift the connecting rods on both sides to drive the stopper to descend, and then the second step is to rotate the rotating rod to the initial position to align with the positioning slot, and the third step is to directly descend and pull the connecting column to remove and separate the entire connecting drill bit device from the mounting device. The operation process is simple and labor-saving, and the replacement is convenient, which greatly improves the drilling efficiency of steel structure workpieces and is beneficial to the production efficiency of the factory.

[0025] 3. Beneficial effects

[0026] Compared with the prior art, the advantages of the present invention are:

[0053] The present invention can be implemented in that when the connecting drill device is installed on the installation device, it only needs to first extend the connecting drill device into the through groove 2 of the installation box 1, at this time, the clamping assembly 8 will fix the connecting column 25 to ensure the subsequent normal processing, and then the second step is to rotate the rotating rod 13 to make the fixing rod 14 rotate into the fixing groove 4, and the fixing rod 14 is limited and blocked by the stopper 19. Through these two steps, the connecting drill device and the installation device can be fixed, and the installation of the drill bit is simple and convenient; when disassembling or replacing the connecting drill device, it only needs to first lift the connecting rods 21 on both sides to drive the stopper 19 to descend, and then the second step is to rotate the rotating rod 13 to the initial position to align with the positioning groove 15, and the third step is to directly descend and pull the connecting column 25 to remove and separate the entire connecting drill device from the installation device. The operation process is simple and labor-saving, and the replacement is convenient, which greatly improves the drilling efficiency of steel structure workpieces and is beneficial to the production efficiency of the factory.

[0054] The drill bit connector of the present invention is used for high-precision drilling processing, because the connecting drill bit device in the present invention is fixed by the cooperation of the first tooth plate 9 on the connecting column 25 with the linkage component 6 and the clamping component 8, and then the subsequent drilling processing is carried out. Because of more transmission effects, when slight errors occur in the drilling processing, the errors can be amplified step by step through the transmission of the linkage component 6 and the clamping component 8, so that the errors can be more easily detected by the staff, so as to carry out subsequent processing on the error parts, thereby avoiding the failure to detect the slight errors in the existing processing, resulting in the influx of unqualified parts into production and the market, which seriously affects the product assembly quality and the company's reputation. In particular, a drill bit connector for steel structure processing that is easy to replace in the present scheme is mainly used for the processing of high-quality steel structure workpieces, and its processing added value is large. The economic benefits of processing can supply high-frequency parts replacement, and the added benefits and benefits of high-precision processing and replacement of parts to the factory are far greater than the cost of replacing parts, which has a more long-term beneficial effect on the company.

[0055] Working principle:

[0056] The installation device is fixed on a drilling machine used for steel structure processing. When in use, first take the connecting drill device of the model to be drilled, extend the connecting column 25 into the through groove 2, and make the two fixing rods 14 on the connecting column 25 extend into the through groove 2 along the two positioning grooves 15. After extending into a certain position, the first tooth plates 9 on both sides of the connecting column 25 are respectively meshed with the linkage gears 603 on both sides to drive the linkage gears 603 on both sides to rotate, and the linkage gears 603 on both sides rotate in opposite directions, thereby driving the second rotating shaft 602 and the worm 604 to rotate, and the left worm 604 drives the left worm wheel 601 to rotate counterclockwise. The right worm 604 drives the right worm wheel 601 to rotate clockwise, thereby driving the first rotating shaft 5 and the transmission gear 7 to rotate, and the transmission gears 7 on both sides respectively drive the second tooth plates 805 on both sides to move in the direction of approaching each other, thereby driving the moving plates 803 and the clamping blocks 804 on both sides to approach each other and approach the middle connecting column 25. Finally, when the upper end of the connecting column 25 is in place, the clamping blocks 804 on both sides will clamp the connecting column 25, and fix the connecting column 25 well. The fixing method is simple and effective, avoiding the existing cumbersome fixing method, and is simple to install and replace, ensuring the stability of subsequent drilling of steel structure workpieces.

[0057] When the clamping block 804 clamps the connecting column 25, the fixing rod 14 is also in the same plane as the fixing groove 4, and then the rotating rod 13 is rotated to 90 degrees, thereby driving the rotating column 12 and the fixing rod 14 to rotate, and the two fixing rods 14 will be respectively rotated into the fixing groove 4, as shown in FIG. Fig.10 When passing through the stopper 19, the stopper 19 can be pressed down and the spring 18 can be compressed at the same time. When the fixing rod 14 passes over the stopper 19, the stopper will return to its original position due to the action of the spring 18. Figure 8 As shown, the fixing rod 14 can be restricted to prevent the fixing rod 14 from rotating during subsequent drilling work and causing the connecting drill bit device to detach from the mounting device. The protective effect is good, and the connecting drill bit device is further effectively fixed to improve the subsequent drilling processing effect.

[0058] When it is necessary to change the drill bit model or disassemble the connecting drill bit device after processing, the connecting rods 21 on both sides can be lifted up, and the stopper 19 can be driven down by the lever action, and the spring 18 can be compressed. At this time, the stopper 19 is completely sunk into the vertical groove 16 and no longer blocks the fixing rod 14. By rotating the rotating rod 13 ninety degrees, the rotating rod 13 is just aligned with the positioning groove 15, and then the connecting column 25 is pulled downward, and the rotating rod 13 descends along the positioning groove 15. At the same time, the first toothed plate 9 drives the linkage gears 603 on both sides to rotate in the opposite direction. After a series of transmissions, the clamping blocks 804 on both sides are driven to move away from each other. At this time, the connecting drill bit device can be taken out from the through groove 2 of the installation box 1. The removal is simple and convenient, which is conducive to the subsequent replacement of the connecting drill bit device.
