According to the invention, when the connecting drill bit device is installed on the installation device, the connecting drill bit device is inserted into the through groove 2 of the installation box 1 in the first step, at the moment, the clamping component 8 can fix the connecting column 25 to ensure the subsequent normal processing, then the rotating rod 13 is rotated in the second step to enable the fixing rod 14 to rotate into the fixing groove 4, the rotating rod 13 is limited and blocked by the stop block 19, the connecting drill bit device and the installation device can be fixed through the two steps, and the installation of the drill bit is simple and convenient; when dismantling or changing and connecting the drill bit device, only need the connecting rod 21 of first step lift both sides to drive dog 19 and descend, then the second step rotates dwang 13 to initial position alignment constant head tank 15, and the third step directly descends and stimulates spliced pole 25, takes out the separation with whole connection drill bit device from the installation device, and operation process is simple and laborsaving, and it is convenient to change, has greatly improved the drilling machining efficiency of steel construction work piece, is favorable to the productivity effect of mill simultaneously.
The drill connecting piece is used for high-precision drilling, the drill connecting device is fixed by matching the first toothed plate 9 on the connecting column 25 with the linkage assembly 6 and the clamping assembly 8, and then subsequent drilling is carried out, so that when a drilling worker has a slight error, the error can be amplified in a first-stage mode through the transmission of the linkage assembly 6 and the clamping assembly 8 due to the fact that a large amount of transmission is used, the error can be detected more easily by workers, subsequent processing is carried out on the error piece, the problem that the small error cannot be detected during the existing processing, so that an unqualified piece flows into production and markets, the product assembly quality and company public praise are seriously influenced is avoided, and particularly, the drill connecting piece for steel structure processing, which is convenient to replace, is mainly used for processing high-quality steel structure workpieces, the processing added value is large, the economic benefit of processing can supply high-frequency part replacement, the additional benefit and the benefit of the high-precision processing and replacement of parts to a factory are far higher than the cost of replacing parts, and the method has a long-term beneficial effect on a company.
The working principle is as follows:
when the mounting device is used, firstly, a connecting drill bit device of a type to be drilled is held, the connecting column 25 extends into the through groove 2, two fixing rods 14 on the connecting column 25 extend into the through groove 2 along the two positioning grooves 15 and extend into a certain position, then the first toothed plates 9 on the two sides of the connecting column 25 are respectively in meshed transmission with the linkage gears 603 on the two sides to drive the linkage gears 603 on the two sides to rotate, the rotation directions of the linkage gears 603 on the two sides are opposite, so that the second rotating shaft 602 and the worm 604 are driven to rotate, the worm 604 on the left side drives the worm wheel 601 on the left side to rotate anticlockwise, the worm 604 on the right side drives the worm wheel 601 on the right side to rotate clockwise, the first rotating shaft 5 and the transmission gear 7 are driven to rotate, and the second toothed plates 805 on the two sides are respectively driven to move towards the directions close to each other by the transmission gears 7 on the two sides, and then drive both sides movable plate 803 and grip block 804 and be close to each other and be close to towards middle spliced pole 25, finally after the spliced pole 25 upper end target in place, the spliced pole 25 can be cliied to the grip block 804 of both sides, carries out fine fixed action to spliced pole 25, and the fixed mode is simple effective, has avoided current loaded down with trivial details fixed mode, and the installation is changed simply, has guaranteed follow-up stability to steel construction work piece drilling.
After the connecting column 25 is clamped by the clamping block 804, the fixing rod 14 and the fixing groove 4 are on the same plane at the moment, and then the rotating rod 13 is rotated to ninety degrees, so that the rotating column 12 and the fixing rod 14 are driven to rotate, the two fixing rods 14 can respectively rotate into the fixing groove 4, as shown in fig. 10, when passing through the stop block 19, the stop block 19 can be pressed down, the spring 18 is compressed, after the fixing rod 14 passes over the stop block 19, the stop block can restore to the original position due to the action of the spring 18, as shown in fig. 8, the fixing rod 14 can be limited, the situation that the connecting drill bit device is separated from the mounting device due to the rotation of the fixing rod 14 in the subsequent drilling work can be prevented, the protection effect is good, the connecting drill bit device can be further effectively fixed, and the subsequent drilling processing effect is improved.
Need change the drill bit model or when dismantling and connect the drill bit device after processing, the accessible lifts the connecting rod 21 of both sides, it descends to drive dog 19 through leverage, and compression spring 18, dog 19 is absorbed in completely in erecting groove 16 and is no longer keeping off dead lever 14 this moment, through gyration dwang 13 ninety degrees, dwang 13 just in time aims at constant head tank 15 this moment, stimulate spliced pole 25 downwards again, dwang 13 descends along constant head tank 15, first pinion rack 9 drives the linkage gear 603 counter-rotation of both sides respectively simultaneously, and then drive both sides grip block 804 and keep away from the removal each other after a series of transmissions, can take out from leading to the groove 2 of connecting the drill bit device from install bin 1 this moment, it is simple and convenient to take out, be favorable to subsequent connection drill bit device to change.
According to the invention, when the connecting drill bit device is installed on the installation device, the connecting drill bit device is inserted into the through groove 2 of the installation box 1 in the first step, at the moment, the clamping component 8 can fix the connecting column 25 to ensure the subsequent normal processing, then the rotating rod 13 is rotated in the second step to enable the fixing rod 14 to rotate into the fixing groove 4, the rotating rod 13 is limited and blocked by the stop block 19, the connecting drill bit device and the installation device can be fixed through the two steps, and the installation of the drill bit is simple and convenient; when dismantling or changing and connecting the drill bit device, only need the connecting rod 21 of first step lift both sides to drive dog 19 and descend, then the second step rotates dwang 13 to initial position alignment constant head tank 15, and the third step directly descends and stimulates spliced pole 25, takes out the separation with whole connection drill bit device from the installation device, and operation process is simple and laborsaving, and it is convenient to change, has greatly improved the drilling machining efficiency of steel construction work piece, is favorable to the productivity effect of mill simultaneously.
