Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a machining drilling device. Background Technology

[0002] A disc flange is a component used to connect shafts. A flange connection, or flange joint, refers to a detachable connection consisting of a flange, gasket, and bolts forming a combined sealing structure. Any connecting component that uses bolts to seal the perimeter of two planes is generally called a "flange." Flanges require evenly distributed holes along the radial direction.

[0003] According to Chinese Patent Publication No. CN112045226B, a machining drilling device includes a drilling mechanism, a support plate, a fixing mechanism, and a chip removal mechanism. The top of the chip removal mechanism is fixedly connected to the bottom of the fixing mechanism, the top rear side of the fixing mechanism is fixedly connected to the bottom of the support plate, and the top front of the support plate is fixedly connected to the rear side of the drilling mechanism. A chip removal hole is provided in the middle of the drilling table. This machining drilling device, through its fixing mechanism, allows for the following steps during drilling: first, the right side of the clamping plate is rotated to the top of the clamping plate; then, the workpiece is placed on the drilling table. A first motor starts, driving a bidirectional lead screw to rotate. The first ball nut and the sliding groove work together to bring the clamping plates closer together to clamp the workpiece. Rotating the clamping plate rotates the anti-detachment plate on the bottom right side of the clamping plate onto the workpiece. A spring then presses the clamping plate firmly onto the workpiece. This effectively adjusts and fixes different workpieces, and the fixing operation is simple.

[0004] When using the aforementioned patent, only one hole can be drilled at a time for flange processing. However, flange processing often requires drilling multiple holes, which necessitates repeated drilling and disassembly / reassembly of the flange. This not only affects the processing quality of the flange but also reduces work efficiency. Therefore, a mechanical drilling device is proposed to solve the aforementioned problems.

By setting a first motor, threaded rod, lifting block, connecting rod, and connecting block, multiple uprights can be moved simultaneously, making it easy to adjust the position of the drill bit according to the drilling position of the flange, eliminating the need for individual adjustment of the drill bit position, thereby improving work efficiency.

[0018] 3. This machining drilling device, by setting a telescopic rod, can restrict the second motor, so that the second motor can drive the upright to rotate and move with the upright, thereby making the operation of the second motor more stable. By setting a stop block, the upright can be restricted, so that the upright cannot move up and down, thereby making the drilling more stable and preventing it from shaking up and down.

[0021] 6. This machining drilling device, by setting up a water tank, water pump, water pipe, annular pipe and nozzle, can spray coolant onto the drilling site during drilling, thereby cooling the drill bit and preventing it from overheating and affecting its service life. It can also prevent the flange from deforming due to excessive temperature during drilling.

The moving rod 607 moves through the arc-shaped groove 606 and is slidably connected to the inner wall of the movable groove. The moving block 608 is fixedly connected to the top of the moving rod 607, and the moving block 608 is slidably connected to the inner wall of the movable groove.

[0035] Preferably, the card holder 609 is L-shaped and is provided with an elastic pad. The card holder 609 is provided with a flange 7, and the inner wall of the flange 7 is in contact with the elastic pad. The purpose of providing the elastic pad is to improve the fixing effect.

[0036] Preferably, a fixing hole is provided on the top of the intermediate block 605, and a cover plate 610 is provided on the top of the intermediate block 605. A fixing bolt 611 is provided on the cover plate 610, and the fixing bolt 611 passes through the cover plate 610 and is threadedly connected to the fixing hole. The cover plate 610 and the fixing bolt 611 are provided to facilitate the maintenance of the fixing mechanism 6.

[0037] Preferably, a second hydraulic cylinder 612 is fixedly connected to the bottom of the workbench 1, and a lifting plate 613 is fixedly connected to the bottom of the movable end of the second hydraulic cylinder 612. A sliding groove 614 is provided on the top of the lifting plate 613, and the inner wall of the sliding groove 614 is slidably connected to the bottom of the moving rod 607.

[0039] Working principle: The flange 7 to be drilled is placed on the intermediate block 605. The third motor 602 is started, driving the worm gear 603 to rotate, which in turn drives the worm wheel 604. The rotating worm wheel 604, under the action of the arc groove 606, moves the moving rod 607 outwards, which in turn moves the moving block 608 outwards. The moving block 608 then moves the mounting base 609 outwards, thus securing the inner wall of the flange 7. After securing, the second hydraulic cylinder 612 is started, causing the lifting plate 613 to rise. This, in turn, drives the moving rod 607 to rise, which in turn drives the moving block 608 to rise, and finally, the mounting base 609 to rise, facilitating drilling of the flange 7 and preventing over-drilling. During the process, if the workbench 1 is damaged, the coolant in the water tank 9 is pumped through the water pipe 12 into the annular pipe 13 by starting the water pump 11. Then, the coolant is sprayed from the nozzle 14 onto the drill hole on the flange 7 through the annular pipe 13, thereby cooling the drill bit 510. This prevents the drill bit 510 from overheating and causing workpiece deformation, improves the stability of the drilling and the quality of the flange 7, and also extends the service life of the drill bit 510. The waste chips generated during drilling are discharged into the water tank 9 from the drain outlet 15 along with the coolant, thus cleaning the waste chips on the workbench 1. The waste chips are filtered and intercepted by the filter screen 10 in the water tank 9, and the coolant passes through the filter screen 10 for easy reuse, realizing the recycling of coolant, which is more economical and environmentally friendly.
