Description

Technical Field

[0001] This invention relates to the field of drilling technology, specifically to a hole-opening device for manufacturing machine tool parts. Background Art

[0002] In the machine tool parts manufacturing industry, the drilling process is a crucial step, as its processing quality and efficiency affect the performance of parts and the progress of the production process. However, traditional machine tool parts drilling equipment has some problems. In terms of debris removal, it restricts the improvement of production efficiency. Traditional drilling equipment generates a large amount of debris during processing. If this debris is not cleaned in time, it will bring a series of adverse effects. On the one hand, debris accumulated in the processing area can easily enter the transmission components and precision structures of the equipment, accelerating the wear of parts, reducing the service life of the equipment, and increasing the maintenance cost of the equipment. Debris entering critical parts such as screws and guide rails can cause jamming, decreased accuracy, and affect the subsequent drilling position accuracy and processing stability. On the other hand, the presence of debris can also interfere with the processing process, making it difficult to guarantee processing accuracy. Accumulated debris may block the feed path of the drill bit, causing problems such as drilling position deviation and inconsistent hole diameter, reducing the processing quality of parts and increasing the defect rate. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a hole-opening device for manufacturing machine tool parts. This device utilizes a single-axis cylinder of the opening and closing mechanism in conjunction with a stepper motor to drive a sliding block, thereby moving the opening and closing plate and opening the channel below the processing area. This facilitates the removal of debris. The guiding device works closely with the opening and closing mechanism. When the opening and closing mechanism opens the channel, the guide block, rotating frame, and rollers push the rotating rod to lift one end of the placement plate, allowing the debris to be smoothly poured into the channel under gravity. After cleaning, the device can be easily reset, thus improving cleaning efficiency while completing the cleaning process.

[0044] In use, drilling is a common and critical machining process in the manufacturing of machine tool parts. This drilling equipment realizes the drilling operation through the coordinated operation of various devices, and also has a cleaning function. The base 1 serves as the basic support structure of the entire equipment, providing a stable installation platform for other devices. The limiting platform 2 and the support plate 3 are fixed to the outer wall of the base 1.

The connecting platform 41 slides on the slide rail 47 through the fixed slider 46 and can move along a specific direction of the base 1. The servo motor 43 is fixed to the outer wall of the base 1, and the adjusting screw 44 at its output end is rotatably connected to the inner wall of the connecting platform 41. When the servo motor 43 starts, the adjusting screw 44 rotates, driving the connecting platform 41 to move. The support bar 451, connecting bar 452 and arc bar 453 of the blocking device 45 are slidably connected to the inner wall of the connecting platform 41. When the connecting platform 41 moves to the opening position, it stops. At this time, the arc bar 453 can protect the adjusting screw 44, making it difficult for the chips during processing to fall onto the adjusting screw 44, thereby ensuring the stable movement of the movable device during subsequent processing and providing a stable positional basis for subsequent opening operations. The setting of the movable device 4 enables the opening device 5 to flexibly open holes at different positions, improving the adaptability of the equipment to the opening requirements of different parts.

[0046] The hole-opening device 5 is the part that realizes the hole-opening operation. The fixed plate 51 is fixedly connected to the inner wall of the connecting platform 41 through the fixed groove 42. The DC motor 52 is fixed to the outer wall of the fixed plate 51. After the DC motor 52 is started, the movable screw 53 at its output end rotates. The positioning block 55 is rotatably connected to the movable screw 53 through the limiting rod 54, and the outer wall of the positioning block 55 is slidably connected to the inner wall of the limiting platform 2, which plays a role in stabilizing the movable screw 53. The movable block 561 of the adjusting device 56 is threadedly connected to the movable screw 53 through the threaded hole 562 and slidably connected to the limiting rod 54 through the limiting hole 563. When the movable screw 53 rotates, the movable block 561 moves along the movable screw 53 under the limitation of the limiting rod 54. The axial movement of 3 is achieved by a telescopic cylinder 564 at the bottom of the movable block 561 and a fixed rod 565. A sliding frame 566 is slidably connected inside a fixed ring 568 at the bottom of the fixed rod 565. A drilling machine 569 is mounted on the top of the sliding frame 566. When drilling is required, the telescopic cylinder 564 is activated, pushing the sliding frame 566 to move between the limit plate 567 and the fixed ring 568. This, in turn, drives the internally fixed drilling machine 569 to move downward. At this time, the drilling machine 569 begins to work and drill holes in the machine tool parts. This design can control the position and feed depth of the drilling machine 569, ensuring the quality of the drilling, while limiting the movement process to prevent overfeeding from damaging the equipment.

[0047] The opening and closing device 6 plays a role in cleaning and auxiliary positioning in the equipment. The fixed frame 611 of the pushing device 61 is fixed to the inner side wall of the base 1. The single-output cylinder 614 is fixed on the fixed block 613. The output end of the single-output cylinder 614 is connected to the contact block 615. The stepper motor 621 of the sliding device 62 is fixed to the outer wall of the fixed frame 611. The rotating screw 622 at its output end is threadedly connected to the sliding block 623. The top of the sliding block 623 is slidably connected to the opening and closing plate 624 through the sliding groove 625. When it is necessary to open the channel for cleaning, the single-output cylinder 614 is started, pushing the contact block 615, which in turn pushes the sliding device 62 to move as a whole. At the same time, the stepper motor 621 is started, the rotating screw 622 rotates, and the sliding block 623 slides on the groove plate 612. Since the inclined surface of the opening and closing plate 624 corresponds to the inclined surface of the support plate 3, when the sliding block 623 moves, it drives the opening and closing plate 624 to move to both sides, opening the lower channel.

[0048] The guide device 63 works in conjunction with the opening and closing device 6 to lift and lower the placement plate 7, facilitating debris removal. The limiting frame 631 and the trapezoidal block 632 are fixed to the inner wall of the base 1. The guide block 6331 of the lifting device 633 is fixedly connected to the connecting rod 634 through the connecting hole 6332, and the guide block 6331 slides on the trapezoidal block 632. The rotating frame 6335 at the top of the extension rod 6333 is rotatably connected to the roller 6336, which rolls at the bottom of the rotating rod 638. When the opening and closing device 6 opens the channel, the guide block 6331 slides on the trapezoidal block 632 as the sliding device 62 moves, driving the extension rod 6333 and the rotating frame 6335 to move. The roller 6336 pushes the rotating rod 638 to rotate around the fixed shaft 637. When the rotating rod 638 rotates, it lifts the placement plate 7 closer to the movable part. One end of the actuator 4 lifts one end of the placement plate 7. As the plate is partially lifted, a portion of it rotates and enters the channel opened by the opening and closing device 6. Gravity then pours the debris generated during the opening process into the channel. After cleaning, the single-shaft cylinder 614 and the stepper motor 621 reverse their movements, closing the channel opened by the opening and closing device 6. Simultaneously, the rotating rod 638 rotates in the opposite direction, causing the placement plate 7 to descend and reset. The protective block 6334 in the guide device 63 effectively prevents the rotating frame 6335 from rotating excessively, ensuring the stability and accuracy of the entire device's operation. The coordinated design of the opening and closing device 6 and the guide device 63 results in a high degree of automation in the cleaning process, convenient operation, improved equipment usability and work efficiency, and avoids the impact of debris accumulation on subsequent processing.
