Description

Technical Field

[0001] This invention relates to the field of parts assembly technology, and more specifically, to a diesel engine parts assembly device. Background Technology

[0002] In the production process of diesel engines, bolts are used to fix the cylinder head and cylinder block. To ensure the processing quality of diesel engines, it is necessary to ensure that the bolts are fully tightened to avoid air, water, and oil leaks caused by poor bolt tightening quality. To ensure work efficiency, bolt tightening devices are often used to tighten the bolts in related technologies.

[0003] Currently, during the assembly of diesel engine parts, it is necessary to manually place the bolts into the corresponding threaded holes in the engine cylinder head. Due to the long length of the bolts, when the bolts are placed in the threaded holes, the axial direction of the bolts generally deviates from the axial direction of the threaded holes by a certain angle. When the bolts are tightened by a tightening device, the bolts may not be able to be properly assembled with the threaded holes, or even the bolts or threaded holes may be damaged. Furthermore, manually placing the bolts into the threaded holes can also cause different bolts to protrude from the threaded holes at different heights, making it inconvenient to tighten the bolts uniformly afterward.

[0004] To address the aforementioned problems, some solutions have been proposed in the prior art. For example, Chinese invention application CN119952458A discloses a diesel engine parts assembly device. This device uses a rotating shaft and a cylinder in a spiral lifting and lowering manner to facilitate the clamping of bolts relative to the threaded holes when they encounter resistance during screwing in. This allows for readjustment of the thread fit between the bolt and the threaded hole, preventing problems such as bolt jamming or damage due to over-tightening, thus improving the bolt tightening quality. However, in actual use, when bolts encounter resistance during screwing in, the bolt and threaded hole may already be jammed. Re-unscrewing the bolt can still cause some damage to both the bolt and the threaded hole, severely affecting the bolt tightening quality. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a diesel engine parts assembly device that can improve the tightening quality.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A diesel engine parts assembly device includes a side plate, characterized in that: a conveyor belt is rotatably mounted on the side plate, and a frame is fixedly mounted on the side wall of the side plate; an mounting plate is vertically slidably mounted on the frame; an electric telescopic rod is installed between the side plate and the frame; and a tightening assembly is provided on the mounting plate. The tightening assembly includes vertical rods uniformly and vertically mounted on the bottom wall of the mounting plate. A tightening rod is rotatably mounted on the vertical rod. A motor is fixedly mounted on the vertical rod. The output end of the motor is provided with a transmission assembly that cooperates with the tightening rod. A sliding groove is opened at the bottom end of the tightening rod. A mounting plate is slidably and sealed in the sliding groove. A clamping assembly is provided on the mounting plate. A first spring is installed between the mounting plate and the sliding groove. Linkage grooves are uniformly opened on the vertical rod. A rotating rod is rotatably mounted in the linkage groove. A push rod is fixedly mounted on the rotating rod. A torque spring is installed between the rotating rod and the vertical rod.

[0008] Furthermore, the transmission assembly includes a linkage rod fixedly installed on the output end of the motor, and the linkage rod is rotatably engaged with the torsion rod. An annular groove is provided on the vertical rod, and a slider that rotatably engages with the annular groove is fixedly installed on the linkage rod. A horizontal groove is provided on the annular groove, and a push block extending into the annular groove is slidably installed in the horizontal groove. A return spring is provided between the push block and the horizontal groove, and the side wall of the push block away from the return spring is inclined.

[0009] Furthermore, a threaded rod is threadedly installed on the side wall of the horizontal groove, and a linkage block that rotates and engages with the threaded rod is slidably installed inside the horizontal groove, and the end of the return spring away from the push block is fixedly connected to the linkage block.

[0010] Furthermore, the clamping assembly includes mounting slots evenly spaced on the mounting plate, a horizontal plate slidably mounted in the mounting slot, a second spring being installed between the horizontal plate and the mounting slot, a groove being formed on the bottom wall of the mounting slot, a clamping plate fixedly connected to the horizontal plate being slidably mounted in the groove, a first through hole extending to the top wall of the mounting plate being formed on the mounting slot, and a locking assembly cooperating with the horizontal plate being provided on the mounting plate.

[0011] Furthermore, the locking assembly includes a vertical groove formed on the mounting plate, a magnetic plate slidably installed in the vertical groove, a third spring being installed between the bottom wall of the magnetic plate and the vertical groove, spring telescopic rods being uniformly fixedly installed on the bottom wall of the magnetic plate, and a fixing plate being fixedly installed on the top wall of the horizontal plate, with fixing holes uniformly formed on the fixing plate to cooperate with the spring telescopic rods.

[0012] Furthermore, the mounting plate is embedded with an electromagnet that repels the magnetic plate, and the electromagnet is electrically connected to the motor.

[0013] Furthermore, a second through hole communicating with the vertical groove is provided on the top wall of the mounting groove, an exhaust pipe communicating with the outside is inserted in the vertical groove, and an intake valve communicating with the outside is inserted in the top wall of the sliding groove.

[0014] Furthermore, a sealing plate for sealing the trench is fixedly installed on the bottom wall of the horizontal plate, and the sealing plate is slidably engaged with the mounting groove.

[0015] Furthermore, the bottom end of the spring telescopic rod is tapered.

[0016] Furthermore, the inclined surface of the pusher block is a smooth mirror surface.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) This solution sets up a push rod. When the mounting plate and the push rod are out of contact, the torque spring extends and drives the push rod to rotate through the rotating rod. Then, during the rotation of the rotating rod, it gradually contacts the bolt and straightens the bolt. During the screwing of the bolt, the push rod can limit the bolt, thereby preventing the bolt from being too long and offset, which would damage the bolt. When the mounting plate contacts the push rod again, the mounting plate will apply a downward pushing force to the push rod. Then, under the action of the pushing force, the push rod resets and drives the rotating rod to rotate. During the rotation of the rotating rod, the torque spring begins to store force, which plays a role in improving the tightening quality. (2) This solution sets up a transmission component, which drives the torque rod to rotate during the rotation of the push block. When the bolt is finished being tightened, the bolt can no longer rotate. Then, under the action of the thrust, the slider slides along the horizontal groove and squeezes the return spring, thereby effectively avoiding the bolt from being over-tightened and damaged. When it is necessary to adjust the maximum torque of the bolt, the user can rotate the threaded rod, and then the threaded rod drives the linkage block to slide along the horizontal groove, thereby changing the deformation of the return spring, and thus adjusting the resistance when the slider pushes the push block to move, that is, changing the torque force when tightening, and further improving the tightening quality. (3) By setting up a clamping component, the airflow in the slide is squeezed and flows into the mounting groove through the first through hole during the upward movement of the mounting plate. Then the airflow drives the clamping plate to clamp the bolt through the horizontal plate. At the same time, when the motor starts, the electromagnet can drive the spring telescopic rod to fix the clamping plate, thereby avoiding the influence of different bolt sizes on the tightening quality and further improving the tightening quality.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 8 A diesel engine parts assembly device includes a side plate 1, characterized in that: a conveyor belt 2 is rotatably mounted on the side plate 1, and a frame 3 is fixedly mounted on the side wall of the side plate 1, a mounting plate 4 is vertically slidably mounted on the frame 3, an electric telescopic rod 5 is installed between the side plate 1 and the frame 3, and a tightening assembly 6 is provided on the mounting plate 4; The tightening assembly 6 includes vertical rods 601 uniformly and vertically installed on the bottom wall of the mounting plate 4. A tightening rod 602 is rotatably installed on the vertical rod 601. A motor 603 is fixedly installed on the vertical rod 601. A transmission assembly 7 that cooperates with the tightening rod 602 is provided on the output end of the motor 603. A sliding groove is opened at the bottom end of the tightening rod 602. A mounting plate 604 is slidably and sealed in the sliding groove. A clamping assembly 8 is provided on the mounting plate 604. A first spring 605 is installed between the mounting plate 604 and the sliding groove. A linkage groove is uniformly opened on the vertical rod 601. A rotating rod 606 is rotatably installed in the linkage groove. A push rod 607 is fixedly installed on the rotating rod 606. A torque spring 608 is installed between the rotating rod 606 and the vertical rod 601.

[0022] In use, the workpiece to be assembled is transported to the bottom of the frame 3 via the conveyor belt 2. Then, the electric telescopic rod 5 drives the mounting plate 4 to move downward. During the downward movement of the mounting plate 4, the mounting plate 4 drives the torque rod 602 to move downward via the vertical rod 601. During the downward movement of the torque rod 602, the bolt 11 gradually enters the slide groove. As the bolt 11 moves into the slide groove, it drives the mounting plate 604 to move upward. At this time, the first spring 605 is compressed and has a tendency to return to its original position. Then, as the mounting plate 604 moves upward, it gradually disengages from the push rod 607. At this time, the torque spring 608 drives the rotating rod 606 to rotate. During the rotation of the rotating rod 606, it gradually contacts the bolt 11 and aligns the bolt 11. As the mounting plate 604 moves upward, the clamping assembly 8 will... Bolt 11 is clamped, and then motor 603 drives torque rod 602 to rotate through transmission assembly 7. During the rotation of torque rod 602, bolt 11 is rotated through mounting plate 604 and clamping assembly 8, and bolt 11 is screwed in. As bolt 11 is screwed in, first spring 605 extends and drives mounting plate 604 to move downward. During the screwing in of bolt 11, push rod 607 can limit bolt 11, thereby preventing bolt 11 from being damaged due to excessive deviation. When mounting plate 604 contacts push rod 607 again, mounting plate 604 will apply downward pushing force to push rod 607. Under the action of pushing force, push rod 607 resets and drives rotating rod 606 to rotate. During the rotation of rotating rod 606, torque spring 608 begins to store force, which plays a role in improving the tightening quality.

[0023] like Figure 6 , Figure 7As shown, the transmission assembly 7 includes a linkage rod 701 fixedly installed on the output end of the motor 603, and the linkage rod 701 is rotatably engaged with the torsion rod 602. An annular groove is provided on the vertical rod 601, and a slider 702 that rotatably engages with the annular groove is fixedly installed on the linkage rod 701. A horizontal groove is provided on the annular groove, and a push block 703 extending into the annular groove is slidably installed in the horizontal groove. A return spring 704 is provided between the push block 703 and the horizontal groove, and the side wall of the push block 703 away from the return spring 704 is inclined.

[0024] A threaded rod 705 is threadedly installed on the side wall of the horizontal groove, and a linkage block 706 that rotates and engages with the threaded rod 705 is slidably installed in the horizontal groove. The end of the return spring 704 away from the push block 703 is fixedly connected to the linkage block 706.

[0025] By adopting the above technical solution, the motor 603 rotates, driving the linkage rod 701 to rotate, and the linkage rod 701 rotates, driving the slider 702 to rotate along the annular groove. Then, as the slider 702 rotates, it gradually contacts the inclined surface of the push block 703 and applies a pushing force to the inclined surface of the push block 703. Under the action of the pushing force, the push block 703 begins to rotate, and during the rotation of the push block 703, it drives the tightening rod 602 to rotate. When the bolt 11 is tightened to the end, the bolt 11 can no longer rotate. Then, under the action of the pushing force, the slider 702 slides along the horizontal groove and squeezes the return spring 704, thereby effectively avoiding the bolt 11 from being over-tightened and damaged, and further improving the tightening quality.

[0026] Since the required tightening force may vary depending on the location or type of bolt 11, when adjusting the maximum tightening force of bolt 11, the user can rotate the threaded rod 705. The threaded rod 705 then drives the linkage block 706 to slide along the horizontal groove. Since the elastic force of the return spring 704 is proportional to its own elastic coefficient and deformation, and the elastic coefficient of the return spring 704 remains constant, when the linkage block 706 moves towards the push block 703, the linkage block 706 will compress the return spring 704, thereby increasing the compression of the return spring 704. This increases the resistance when the slider 702 pushes the push block 703 along the horizontal groove, thus increasing the tightening force of bolt 11. Similarly, when the linkage block 706 moves away from the push block 703, the return spring 704 extends, thereby reducing the resistance when the slider 702 pushes the push block 703, thus reducing the tightening force of bolt 11 and further improving the tightening quality.

[0027] like Figure 2 , Figure 3As shown, the clamping assembly 8 includes mounting grooves 803 evenly distributed on the mounting plate 604. A horizontal plate 801 is slidably installed in the mounting groove 803. A second spring 802 is installed between the horizontal plate 801 and the mounting groove 803. A groove is formed on the bottom wall of the mounting groove 803. A clamping plate 804 fixedly connected to the horizontal plate 801 is slidably installed in the groove. A first through hole 805 extending to the top wall of the mounting plate 604 is formed on the mounting groove 803. A locking assembly 9 that cooperates with the horizontal plate 801 is provided on the mounting plate 604.

[0028] The locking assembly 9 includes a vertical groove 901 formed on the mounting plate 604. A magnetic plate 902 is slidably installed in the vertical groove 901. A third spring 903 is installed between the bottom wall of the magnetic plate 902 and the vertical groove 901. Spring telescopic rods 904 are uniformly fixedly installed on the bottom wall of the magnetic plate 902. A fixing plate 905 is fixedly installed on the top wall of the horizontal plate 801. Fixing holes 906 that cooperate with the spring telescopic rods 904 are uniformly formed on the fixing plate 905.

[0029] An electromagnet 907 is embedded in the mounting plate 604, which repels the magnet plate 902, and the electromagnet 907 is electrically connected to the motor 603.

[0030] By adopting the above technical solution, during the upward movement of the mounting plate 604, the airflow in the groove is compressed and flows into the mounting groove 803 through the first through hole 805, increasing the pressure in the mounting groove 803. After the mounting plate 604 disengages from the push rod 607, the horizontal plate 801 experiences a greater thrust from the gas than the elastic force of the second spring 802. Then, under the action of the airflow thrust, the horizontal plate 801 slides along the mounting groove 803. At this time, the second spring 802 is stretched and has a tendency to return to its original position. During the sliding process of the horizontal plate 801... The clamping plate 804 moves and gradually comes into contact with the bolt 11 during its movement, clamping the bolt 11. As the mounting plate 604 continues to move upward, the horizontal plate 801 experiences increasing gas thrust, thus enhancing the clamping effect of the clamping plate 804 on the bolt 11. When the bottom end of the tightening rod 602 is about to contact the workpiece to be assembled, the electric telescopic rod 5 stops extending. At this point, the motor 603 can be started to perform the tightening operation, thereby avoiding the influence of different bolt sizes on the tightening quality and further improving the tightening quality.

[0031] When the motor 603 is energized, the electromagnet 907 is energized and generates an electromagnetic field. Under the action of the electromagnetic field, the magnet plate 902 drives the spring telescopic rod 904 to move downward. At this time, the third spring 903 is compressed and has a tendency to recover. During the downward movement of the spring telescopic rod 904, it gradually inserts into the fixing hole 906 and limits the horizontal plate 801 through the fixing plate 905. At this time, some of the spring telescopic rods 904 that are not inserted into the fixing hole 906 are compressed and have a tendency to recover, which can limit the clamping plate 804, thereby improving the clamping effect of the bolt 11 and further improving the tightening effect.

[0032] like Figure 2 , Figure 3 , Figure 5 As shown, a second through hole 101 communicating with a vertical groove 901 is provided on the top wall of the mounting groove 803. An exhaust pipe 102 communicating with the outside is inserted into the vertical groove 901. An intake valve 103 communicating with the outside is inserted into the top wall of the sliding groove.

[0033] A sealing plate 104 for sealing the trench is fixedly installed on the bottom wall of the horizontal plate 801, and the sealing plate 104 slides in conjunction with the mounting groove 803.

[0034] By adopting the above technical solution, when the magnet plate 902 drives the spring telescopic rod 904 to insert, the magnet plate 902 disengages from the second through hole 101. At this time, the airflow in the horizontal groove flows through the second through hole 101 into the vertical groove 901, and flows to the outside through the exhaust pipe 102 on the top wall of the vertical groove 901. Then, when the tightening is completed or the tightening operation stops, as the motor 603 is de-energized, the magnetic field of the electromagnet 907 disappears. Then, the third spring 903 extends and drives the magnet plate 902 to move upward. During the upward movement of the magnet plate 902, the second through hole 101 is blocked again. At the same time, during the upward movement of the magnet plate 902, the spring telescopic rod 904 disengages from the fixing hole 906. When the second spring 802 contracts and drives the horizontal plate 801 to reset, the clamping plate 804 is also reset and disengaged from the bolt 11 during the reset process. Then, as the output end of the electric telescopic rod 5 contracts, the mounting plate 4 moves upward. The mounting plate 4 drives the tightening rod 602 to move upward and reset via the vertical rod 601. This prevents the clamping plate 804 from clamping the bolt 11 too tightly when the tightening operation is stopped midway. This would prevent the bolt 11 from being damaged and affecting the tightening quality if the clamping plate 804 is too tightly clamped when the tightening operation is stopped midway. When the first spring 605 extends and drives the mounting plate 604 to move downward, the slide groove draws air from the outside through the air inlet valve 103, which serves to prepare for the next operation.

[0035] During the movement of the horizontal plate 801, the sealing plate 104 is moved, and the sealing plate 104 can block the groove when it moves, thereby preventing the first through hole 805 from communicating with the outside through the horizontal groove and the groove, which would affect the clamping effect of the bolt 11.

[0036] like Figure 3 , Figure 7 As shown, the bottom end of the spring telescopic rod 904 is tapered.

[0037] The inclined surface of the pusher block 703 is a smooth mirror surface.

[0038] By adopting the above technical solution, by making the bottom end of the spring telescopic rod 904 conical, it is easier for the spring telescopic rod 904 to be inserted into the fixing hole 906, and by making the inclined surface of the push block 703 a smooth mirror surface, the friction between the push block 703 and the slider 702 can be reduced, thereby reducing the degree of wear between the push block 703 and the slider 702.

[0039] Instructions for use: During use, the workpiece to be assembled is transported to the bottom of the frame 3 via the conveyor belt 2. Then, the electric telescopic rod 5 drives the mounting plate 4 to move downward. During the downward movement of the mounting plate 4, the mounting plate 4 drives the torque rod 602 to move downward via the vertical rod 601. As the torque rod 602 moves downward, the bolt 11 gradually enters the slide groove, causing the mounting plate 604 to move upward. Then, as the mounting plate 604 moves upward, it gradually disengages from the push rod 607. At this time, the torque spring 608 drives the rotating rod 606 to rotate and gradually contact the bolt 11, thus tightening the bolt 11. As the mounting plate 604 moves upward, the clamping assembly 8 clamps the bolt 11. Then, the motor 603 drives the torque rod 602 to rotate through the transmission assembly 7. During the rotation of the torque rod 602, the bolt 11 can be rotated through the mounting plate 604 and the clamping assembly 8, and the bolt 11 is screwed in. As the bolt 11 is screwed in, the first spring 605 extends and drives the mounting plate 604 to move downward. During the screwing in of the bolt 11, the push rod 607 can limit the bolt 11, thereby preventing the bolt 11 from being damaged due to excessive deviation.

[0040] When tightening is required, the motor 603 rotates, driving the tightening rod 602 to rotate via the slider 702 and pusher 703. When the bolt 11 is fully tightened, it can no longer rotate. Under the thrust, the slider 702 slides along the horizontal groove and compresses the return spring 704, effectively preventing the bolt 11 from being over-tightened and damaged. When adjusting the maximum tightening force of the bolt 11, the user can rotate the threaded rod 705. The threaded rod 705 then drives the linkage block 706 to slide along the horizontal groove, changing the deformation of the return spring 704 and consequently altering the resistance when the slider 702 pushes the pusher 703.

[0041] When it is necessary to clamp the bolt 111, during the upward movement of the mounting plate 604, the airflow in the groove is compressed and flows into the mounting groove 803 through the first through hole 805. Then, under the action of the airflow thrust, the horizontal plate 801 slides along the mounting groove 803. During the sliding of the horizontal plate 801, it drives the clamping plate 804 to move. During the movement of the clamping plate 804, it gradually contacts the bolt 11 and clamps the bolt 11. When the motor 603 is energized, the electromagnet 907 is energized and generates an electromagnetic field. Then, under the action of the electromagnetic field, the magnet plate 902 drives the spring telescopic rod 904 to move downward. At this time, the third spring 903 is compressed and has a tendency to recover. During the downward movement of the spring telescopic rod 904, it gradually inserts into the fixing hole 906 and limits the horizontal plate 801 through the fixing plate 905.

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 its improved concepts, should be covered within the scope of protection of the present invention.
