A drilling device for crankshaft production

Abstract

This invention discloses a drilling device for crankshaft production, relating to the field of drilling equipment. It includes a processing table, on which a chip removal box and two electrically controlled clamps are mounted. Two crankshaft rods are placed on the processing table, and the electrically controlled clamps are used to hold the crankshaft rods. It should be noted that, in this embodiment of the invention, during the drilling process of the crankshaft rods, when the electrically controlled clamps are in position, the holes on the lifting isolation plate and the buffer isolation plate are aligned with the crankshaft rods, ensuring stable clamping. Furthermore, if the drill rod experiences excessive wear or breakage, the buffer isolation plate stops moving upwards, and simultaneously triggers an emergency stop switch, causing the motor to stop abruptly, pausing the drilling operation and preventing insufficient drilling depth. In addition, during the movement of the sliding drill table, the cleaning integrated frame drives the cleaning sleeve to clean the drill rod, preventing iron filings from entangled or adhering to it, ensuring the cleanliness of the drill rod, and thus guaranteeing the drilling quality.

Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, and more particularly to a drilling equipment for crankshaft production. Background Technology

[0002] The crankshaft is the most important component in an engine. It bears the force transmitted from the connecting rod and converts it into torque, which is then output through the crankshaft to drive other accessories on the engine. The crankshaft is subjected to the combined effects of centrifugal force from the rotating mass, periodically changing gas inertial force, and reciprocating inertial force, which subject the crankshaft to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, have uniform operation, and good balance.

[0003] During crankshaft machining, a deep hole drilling machine is used to drill holes in the crankshaft. When drilling the crankshaft rod, it is placed on the machine tool's machining table and clamped by an electrically controlled fixture. The motor is then started, driving the sliding drill table to move, which in turn drives the drill rod to drill the crankshaft. However, due to the long length of the drill rod and the depth of the hole, the electrically controlled fixture, after prolonged use, may experience errors in its movement distance or wear. This can easily prevent the fixture from fully clamping the crankshaft, causing vibration during drilling and potentially leading to drill rod breakage. Furthermore, if the drill rod becomes misaligned or the end of a short rod wears excessively or breaks after repeated use, it can cause drilling deviation or insufficient drilling depth, resulting in a defective crankshaft.

[0017] Furthermore, in a preferred embodiment of the present invention, a plurality of buffer push slots are provided on one side of the buffer isolation plate, and a plurality of buffer push rods are installed on the lifting isolation plate, with the plurality of buffer push rods being movably installed in the plurality of buffer push slots respectively;

[0027] Furthermore, in a preferred embodiment of the present invention, an annular drive groove is provided on the cleaning rotating column, and a drive block is installed on the inner wall of the cleaning integrated frame, the drive block being movably installed in the annular drive groove.

[0028] The beneficial effects of the drilling equipment for crankshaft production proposed in this invention are:

[0029] In this invention, by setting up a clamping position detection device, during the drilling process of the crankshaft bar, the electrically controlled clamp squeezes the threaded pressure frame, causing the threaded pressure frame to drive the pressure driven frame to move. The movement of the pressure driven frame drives the pull-down frame to move, causing the pull-down frame to push the lifting rod to rotate via the linkage shaft. The rotation of the lifting rod drives the lifting slide to move, and the movement of the lifting slide drives the lifting seat to move. This causes the lifting seat to move the buffer isolation plate out of the chip box via the lifting isolation plate. At this time, the drill rod can drill through the holes in the lifting isolation plate and the buffer isolation plate. If the electrically controlled clamp is not clamped properly, the holes in the lifting isolation plate and the buffer isolation plate cannot be aligned with the crankshaft bar, thus avoiding the problem of incorrect drilling position.

[0030] Furthermore, in this invention, by setting up a drill rod end detection device, when the lifting seat moves the buffer isolation plate upward via the lifting isolation plate, if the drill rod is long enough, it will drive the wedge-shaped gap detection frame to move vertically within the pull-down groove. If the drill rod is excessively worn or broken, when the buffer isolation plate moves upward, the wedge-shaped gap detection frame will move into the gap at the front end of the drill rod. As the wedge-shaped gap detection frame moves upward, it will be squeezed and moved laterally by the drill rod. The wedge-shaped gap detection frame will drive the buffer isolation plate to move, and the squeezing and moving frame will drive the locking rack to move, so that the locking rack meshes with the positioning rack, thereby stopping the buffer isolation plate from moving upward. The locking rack will move horizontally within the mounting frame, and the push-back spring will be stressed, triggering the emergency stop switch at the same time, thereby stopping the motor and pausing the drilling work to avoid the problem of insufficient drilling depth.

[0031] Furthermore, in this invention, by setting up a drill rod synchronous cleaning device, during the movement of the sliding drill table, the synchronous moving sleeve is driven to move synchronously, causing the synchronous moving sleeve to drive the synchronous moving rod to move. The synchronous moving rod moves within the threaded groove, thereby driving the cleaning rotating column to rotate. When the cleaning rotating column rotates, it squeezes the driving block through the annular driving groove, thereby driving the cleaning integrated frame to move. The cleaning integrated frame slides within the chip removal box, and simultaneously drives the two cleaning sleeves to move. When the cleaning rotating column rotates one revolution, the cleaning integrated frame drives the cleaning sleeves to move back and forth once, cleaning the drill rod and preventing iron filings from entangled or adhering to it, ensuring the cleanliness of the drill rod, and thus ensuring the drilling quality.

[0053] Please refer to the attached instruction manual. Figures 1-14The present invention provides a drilling device for crankshaft production, which includes a processing table 1, a chip box 2 and two electrically controlled clamps 5 installed on the processing table 1, two crankshaft material bars 3 placed on the processing table 1, the electrically controlled clamps 5 used to clamp the crankshaft material bars 3, a sliding drill table 9 slidably installed on the processing table 1, a plurality of drill rods 4 installed on the sliding drill table 9, and a motor 10 installed on the sliding drill table 9.

[0054] Further, please refer to the appendix to the instruction manual. Figures 2-8 The present invention provides a drilling device for crankshaft production, which further includes a clamping position detection device 6. The clamping position detection device 6 is installed on the processing table 1 and is used to detect the clamping position of the electrically controlled fixture 5. Specifically, the clamping position detection device 6 includes a lifting seat 601, a lifting isolation plate 602 is slidably installed in the chip box 2, the lifting seat 601 is installed on the lifting isolation plate 602, a buffer isolation plate 603 is movably installed on one side of the lifting seat 601, and two downward pressing driven frames 618 are movably installed on the processing table 1. The two downward pressing driven frames 618 are connected to the lifting seat 601 in a transmission manner. A threaded downward pressing frame 619 is threadedly installed on the downward pressing driven frame 618, and the electrically controlled fixture 5 moves down to press the threaded downward pressing frame 619. It should be noted that, in this embodiment of the invention, during the drilling process of the crankshaft bar 3, the crankshaft bar 3 is clamped by the electrically controlled clamp 5, and the electrically controlled clamp 5 squeezes the threaded pressure frame 619, causing the threaded pressure frame 619 to drive the pressure driven frame 618 to move. This causes the lifting seat 601 to move out of the chip box 2 through the lifting isolation plate 602 and the buffer isolation plate 603. At this time, the drill rod 4 can drill through the holes on the lifting isolation plate 602 and the buffer isolation plate 603. If the electrically controlled clamp 5 is not clamped properly, the holes on the lifting isolation plate 602 and the buffer isolation plate 603 cannot be aligned with the crankshaft bar 3, thereby avoiding the problem of incorrect drilling position.

[0055] More specifically, in this embodiment of the invention, a drill rod end detection device 7 is installed on the clamping position detection device 6. The drill rod end detection device 7 is used to detect the end of the drill rod 4. The drill rod end detection device 7 includes two wedge-shaped gap detection frames 701, both of which are slidably mounted on the buffer isolation plate 603. It should be noted that, in this embodiment of the invention, when the lifting seat 601 moves the buffer isolation plate 603 upward through the lifting isolation plate 602, if the drill rod 4 is excessively worn or broken, the wedge-shaped gap detection frame 701 moves into the gap at the front end of the drill rod 4 as the buffer isolation plate 603 moves upward. As the wedge-shaped gap detection frame 701 moves upward, it is squeezed and moved laterally by the drill rod 4, causing the wedge-shaped gap detection frame 701 to move the buffer isolation plate 603, thereby triggering the emergency stop switch 710, causing the motor 10 to stop suddenly, pausing the drilling operation, and avoiding the problem of insufficient drilling depth.

[0056] More specifically, in this embodiment of the invention, a drill rod synchronous cleaning device 8 is also included. The drill rod synchronous cleaning device 8 is installed inside the chip removal box 2 and is used to clean the drill rods 4. The drill rod synchronous cleaning device 8 includes a cleaning rotating column 801, which is rotatably installed inside the chip removal box 2. A cleaning integrated frame 802 is movably mounted on the cleaning rotating column 801, and two cleaning sleeves 803 are installed on the cleaning integrated frame 802. The two cleaning sleeves 803 are respectively fitted onto the two drill rods 4. It should be noted that in this embodiment of the invention, during the movement of the sliding drill table 9, the cleaning rotating column 801 rotates. The cleaning rotating column 801 drives the cleaning sleeves 803 to move back and forth through the cleaning integrated frame 802, cleaning the drill rods 4, preventing iron filings from entangled or adhering to the drill rods 4, ensuring the cleanliness of the drill rods 4, and thus ensuring the drilling quality.

[0057] Please continue to refer to the instruction manual appendix. Figures 2-8 Furthermore, the drilling equipment for crankshaft production provided in this embodiment of the invention includes a clamping position detection device 6 that further includes two lifting slides 607. The two lifting slides 607 are installed on both sides of the lifting seat 601. Connecting seats 608 are installed on both sides of the chip box 2. Lifting rods 609 are rotatably installed on both connecting seats 608. The two lifting rods 609 are respectively movably installed on the two lifting slides 607.

[0058] Furthermore, two lifting shafts 610 are installed on the lifting rod 609. One lifting shaft 610 is movably installed inside the lifting slide 607, and the other lifting shaft 610 is rotatably installed on the connecting seat 608. A lifting torsion spring 611 is installed on the inner wall of the connecting seat 608, and the lifting torsion spring 611 is installed on the lifting shaft 610. It should be noted that, in this embodiment of the invention, when the driven frame 618 is pressed down and moves, causing the pull-down frame 613 to move, the pull-down frame 613 causes the lifting rod 609 to rotate. When the lifting rod 609 rotates, it rotates on the connecting seat 608 through one lifting shaft 610, causing the lifting torsion spring 611 to be stressed. At the same time, the rotation of the lifting rod 609 drives the lifting slide 607 to move through the other lifting shaft 610, and the lifting shaft 610 slides inside the lifting slide 607, thereby achieving the purpose of moving the lifting seat 601 through the lifting slide 607.

[0059] More specifically, in this embodiment of the invention, redundant retractable sleeves 612 are installed on both sides of the processing table 1, and pull-down brackets 613 are movably installed in both redundant retractable sleeves 612. A return spring 614 is connected between the redundant retractable sleeves 612 and the pull-down brackets 613. In addition, a push groove 615 is provided on the lifting rod 609, and a linkage shaft 616 is rotatably installed on the pull-down bracket 613. The linkage shaft 616 is movably installed in the push groove 615. It should be noted that, in this embodiment of the invention, when the electrically controlled clamp 5 clamps the crankshaft bar 3, the downward driven frame 618 causes the pull-down frame 613 to move. The pull-down frame 613 pushes the lifting rod 609 to rotate through the linkage shaft 616. At the same time, the linkage shaft 616 slides in the push slide groove 615. The lifting rod 609 drives the lifting slide 607 to move, and the lifting shaft 610 slides in the lifting slide 607. The movement of the lifting slide 607 drives the lifting seat 601 to move, thereby achieving the purpose of moving the lifting isolation plate 602 and the buffer isolation plate 603 out of the chip box 2 through the lifting seat 601.

[0060] Please continue to refer to the instruction manual appendix. Figures 2-8 More specifically, in this embodiment of the invention, both sides of the processing table 1 are provided with pressing grooves 617, and two pressing driven frames 618 are respectively movably installed in the two pressing grooves 617. The pressing driven frames 618 are slidably installed on the pulling frame 613. A pressing spring 621 is installed on the bottom side of the pressing driven frame 618, and the pressing spring 621 is installed on the bottom inner wall of the pressing groove 617.

[0061] Furthermore, a threaded groove 620 is provided on the driven frame 618, and the threaded driven frame 619 is threadedly installed in the threaded groove 620. It should be noted that, in this embodiment of the invention, when the electrically controlled clamp 5 clamps the crankshaft bar 3, the electrically controlled clamp 5 compresses the threaded driven frame 619, causing the threaded driven frame 619 to drive the driven frame 618 to move. The driven frame 618 slides vertically in the driven groove 617, causing the driven spring 621 to be stressed. The movement of the driven frame 618 drives the pull-down frame 613 to move, thereby achieving the purpose of moving the lifting isolation plate 602 and the buffer isolation plate 603 upward. Furthermore, by rotating the threaded driven frame 619, it is made to rotate in the threaded groove 620, which is used to adjust the height of the threaded driven frame 619, thereby adapting it to crankshaft bars 3 of different sizes.

[0062] More specifically, in this embodiment of the invention, a plurality of buffer grooves 604 are provided on one side of the buffer isolation plate 603, and a plurality of buffer push rods 605 are installed on the lifting isolation plate 602. The plurality of buffer push rods 605 are respectively movably installed in the plurality of buffer grooves 604; a buffer spring 606 is installed on the inner wall of the buffer groove 604, and the buffer spring 606 is installed on the buffer push rod 605. It should be noted that, in this embodiment of the invention, when the drill rod 4 pushes the wedge-shaped gap detection frame 701 to move laterally, the wedge-shaped gap detection frame 701 drives the buffer isolation plate 603 to move. The buffer isolation plate 603 moves in the plurality of buffer grooves 604 through the plurality of buffer push rods 605, and causes the buffer spring 606 to be stressed, thus helping the buffer isolation plate 603 to reset.

[0063] Please refer to the instruction manual attached. Figure 2 and Figures 9-11 Furthermore, in the drilling equipment for crankshaft production provided in this embodiment of the invention, the drill rod end detection device 7 further includes a mounting bracket 706, which is mounted on one side of the lifting seat 601. Additionally, a locking rack 707 is slidably mounted on the mounting bracket 706, and a positioning rack box 708 is mounted on one side of the chip box 2. The locking rack 707 meshes with the positioning rack box 708 to restrict the movement of the lifting seat 601. It should be noted that in this embodiment of the invention, when the extrusion transverse frame 705 moves, it drives the locking rack 707 to move, causing the locking rack 707 to mesh with the positioning rack box 708, thereby stopping the movement of the buffer isolation plate 603.

[0064] More specifically, in this embodiment of the invention, the lifting seat 601 is provided with a compression transverse groove 704, a compression transverse frame 705 is movably installed in the compression transverse groove 704, a buffer isolation plate 603 is installed on the compression transverse frame 705, and the compression transverse frame 705 moves to push the locking rack 707 to move.

[0065] Furthermore, a push-back spring 709 is connected between the locking rack 707 and the mounting bracket 706. An emergency stop switch 710 is installed on the inner wall of the mounting bracket 706 and is electrically connected to the motor 10. It should be noted that, in this embodiment of the invention, when the buffer isolation plate 603 drives the wedge-shaped gap detection frame 701 to move upward and is squeezed laterally by the drill rod 4, it drives the buffer isolation plate 603 to move. The buffer isolation plate 603 drives the squeezing lateral movement frame 705 to move within the squeezing lateral movement groove 704, causing the squeezing lateral movement frame 705 to drive the locking rack 707 to move. The locking rack 707 moves horizontally within the mounting bracket 706, causing the push-back spring 709 to be stressed. At the same time, the emergency stop switch 710 is triggered, causing the motor 10 to stop abruptly, pausing the drilling operation and avoiding the problem of insufficient drilling depth.

[0066] Please continue to refer to the instruction manual appendix. Figure 2 and Figures 9-11 More specifically, in this embodiment of the invention, two pull-down grooves 702 are formed on the bottom side of the buffer isolation plate 603, and two wedge-shaped gap detection frames 701 are slidably installed in the two pull-down grooves 702 respectively; an upper pull spring 703 is installed on the inner wall of the pull-down groove 702, and the upper pull spring 703 is installed on the wedge-shaped gap detection frame 701. It should be noted that, in this embodiment of the invention, when the lifting seat 601 moves the buffer isolation plate 603 upward through the lifting isolation plate 602, it moves the wedge-shaped gap detection frame 701 and is blocked by the drill rod 4, so that the wedge-shaped gap detection frame 701 moves vertically in the pull-down groove 702, and the upper pull spring 703 is subjected to force.

[0067] Further, please refer to the appendix to the instruction manual. Figures 2-3 and Figures 12-14 The present invention provides a drilling equipment for crankshaft production. The drill rod synchronous cleaning device 8 further includes a synchronous moving sleeve 804, which is installed on the processing table 1. A synchronous moving rod 805 is movably installed inside the synchronous moving sleeve 804, and a retraction spring 807 is connected between the synchronous moving sleeve 804 and the synchronous moving rod 805.

[0068] Furthermore, a threaded groove 806 is provided on the cleaning rotating column 801, and the bottom side of the synchronous moving rod 805 extends into the threaded groove 806. It should be noted that, in this embodiment of the invention, during the movement of the sliding drill rig 9, the synchronous moving sleeve 804 is moved synchronously, causing the synchronous moving sleeve 804 to move the synchronous moving rod 805. The synchronous moving rod 805 moves within the threaded groove 806, thereby causing the cleaning rotating column 801 to rotate.

[0069] More specifically, in this embodiment of the invention, an annular drive groove 808 is provided on the cleaning rotating column 801, and a drive block 809 is installed on the inner wall of the cleaning integrated frame 802. The drive block 809 is movably installed in the annular drive groove 808. It should be noted that, in this embodiment of the invention, when the cleaning rotating column 801 rotates, it squeezes the drive block 809 through the annular drive groove 808, thereby driving the cleaning integrated frame 802 to move. The cleaning integrated frame 802 slides in the chip box 2, and at the same time, the cleaning integrated frame 802 drives the two cleaning sleeves 803 to move. When the cleaning rotating column 801 rotates one revolution, the cleaning integrated frame 802 drives the cleaning sleeves 803 to move back and forth once, thereby achieving the purpose of cleaning the drill rod 4.

[0070] In summary, the working principle of the drilling equipment for crankshaft production provided in this embodiment of the invention is as follows:

[0071] When the drill rod 4 drills a hole in the crankshaft bar 3, causing the electrically controlled clamp 5 to hold the crankshaft bar 3, the electrically controlled clamp 5 presses the threaded pressure frame 619, causing the threaded pressure frame 619 to drive the pressure driven frame 618 to move. The pressure driven frame 618 slides vertically in the pressure groove 617, causing the pressure spring 621 to be stressed. The movement of the pressure driven frame 618 drives the pull-down frame 613 to move, causing the pull-down frame 613 to push the lifting rod 609 to rotate through the linkage shaft 616. The linkage shaft 616 slides in the push groove 615. It should be noted that when the lifting rod 609 rotates, it rotates on the connecting seat 608 through a lifting shaft 610, which causes the lifting torsion spring 611 to be stressed. At the same time, the rotation of the lifting rod 609 drives the lifting slide 607 to move through another lifting shaft 610, and the lifting shaft 610 slides inside the lifting slide 607. The movement of the lifting slide 607 drives the lifting seat 601 to move, so that the lifting seat 601 drives the buffer isolation plate 603 to move out of the chip box 2 through the lifting isolation plate 602. At this time, the drill rod 4 can drill through the holes on the lifting isolation plate 602 and the buffer isolation plate 603. If the electric control clamp 5 is not clamped in place, it will be impossible to align the holes on the lifting isolation plate 602 and the buffer isolation plate 603 with the crankshaft bar 3, thus avoiding the problem of incorrect drilling position.

[0072] Furthermore, when the lifting seat 601 moves the buffer isolation plate 603 upward via the lifting isolation plate 602, if the drill rod 4 is long enough, it will cause the wedge-shaped gap detection frame 701 to move vertically within the pull-down groove 702, thus subjecting the pull-up spring 703 to force. If the drill rod 4 is excessively worn or broken, when the buffer isolation plate 603 moves upward, the wedge-shaped gap detection frame 701 will move into the gap at the front end of the drill rod 4, and as the wedge-shaped gap detection frame 701 moves upward, it will be squeezed and moved laterally by the drill rod 4, causing the wedge-shaped gap detection frame 701 to move the buffer isolation plate 603. The buffer isolation plate 603 moves through multiple... The buffer push rod 605 moves within multiple buffer push grooves 604, causing the buffer spring 606 to be stressed. The buffer isolation plate 603 moves, driving the extrusion transverse frame 705 to move within the extrusion transverse groove 704. The extrusion transverse frame 705 drives the locking rack 707 to move, causing the locking rack 707 to mesh with the positioning rack box 708, thereby stopping the buffer isolation plate 603 from moving upward. The locking rack 707 moves horizontally within the mounting bracket 706, causing the push-back spring 709 to be stressed. At the same time, the emergency stop switch 710 is triggered, causing the motor 10 to stop suddenly, pausing the drilling work and avoiding the problem of insufficient drilling depth.

[0073] Furthermore, during the movement of the sliding drill rig 9, the synchronous moving sleeve 804 is moved synchronously, causing the synchronous moving sleeve 804 to move synchronous moving rod 805. The synchronous moving rod 805 moves within the threaded groove 806, causing the cleaning rotating column 801 to rotate. When the cleaning rotating column 801 rotates, it squeezes the driving block 809 through the annular driving groove 808, thereby causing the cleaning integrated frame 802 to move. The cleaning integrated frame 802 slides within the chip box 2, and at the same time, the cleaning integrated frame 802 drives the two cleaning sleeves 803 to move. It should be noted that when the cleaning rotating column 801 rotates one revolution, the cleaning integrated frame 802 causes the cleaning sleeve 803 to move back and forth once to clean the drill rod 4, preventing iron filings from getting tangled or attached to the drill rod 4, ensuring the cleanliness of the drill rod 4, and thus ensuring the drilling quality. In addition, when the sliding drill table 9 continues to move, the synchronous moving rod 805 is blocked by the chip box 2, causing the synchronous moving rod 805 to retract into the synchronous moving sleeve 804, and causing the contraction spring 807 to be stressed, without affecting the movement of the sliding drill table 9.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
