Description

Technical Field

[0001] This invention relates to the field of diesel engine assembly equipment technology, specifically to an assembly table for assembling marine diesel engines. Background Technology

[0002] In the process of assembling diesel engines, assembly fixtures are used, such as tilting devices (for tilting the diesel engine to be assembled) and robotic arms (for clamping and positioning workpieces). Existing assembly fixtures are generally mounted on assembly tables. For example, the publication document CN217513848U discloses an assembly table for mounting tilting devices. However, existing assembly tables generally only serve the purpose of mounting assembly fixtures, and their function is relatively simple. When the output shaft of the tilting device bends (because marine diesel engines are heavy, the output shaft of the tilting device will be subjected to a large weight, and it will bend over a long period of use), the lack of detection facilities on the assembly table will prevent workers from knowing the situation in time, which poses certain safety hazards. Summary of the Invention

[0003] The purpose of this invention is to provide an assembly platform for assembling marine diesel engines, in order to solve the problem mentioned in the background art that existing assembly platforms generally only serve the function of installing assembly tools and have a relatively simple function.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an assembly table for assembling marine diesel engines, the assembly fixture including a robotic arm and a tilting assembly, the assembly table including: a platform for mounting the robotic arm and the tilting assembly, a mounting box provided on the platform, a support rod slidably inserted into the top of the inner cavity of the mounting box, a contact member for engaging with the output shaft of the tilting assembly at the top of the support rod, a pressing member at the bottom of the support rod, and an elastic member between the pressing member and the mounting box;

[0005] The mounting box is equipped with a first touch switch located below the pressing component and used to control the flipping assembly to stop working. The first touch switch is connected to the warning device. When the output shaft of the flipping assembly bends, the rotation of the output shaft of the flipping assembly will cause the contact component to move down, causing the support rod to drive the pressing component down to press the first touch switch, disconnecting the power supply of the flipping assembly and energizing the warning device to issue an alarm.

[0006] Preferably, the pressing component includes a mounting plate installed at the bottom of the support rod, a guide block is slidably inserted on the mounting plate, the direction of movement of the guide block is the same as the direction of movement of the support rod, the support rod is provided with an electromagnet for attracting the guide block, and the bottom end of the guide block is provided with a movable plate.

[0007] The mounting plate has a mounting groove on its side wall, and a second touch switch for controlling the operation of the electromagnet is provided in the mounting groove. A pressure block for pressing the second touch switch and a push spring for pushing the pressure block outward are slidably inserted in the mounting groove. The mounting box has a slot on its inner side wall, and a limiting block for restricting the movement of the pressure block is provided in the slot. The bottom end of the limiting block is spaced from the bottom of the inner cavity of the slot.

[0008] Preferably, the limiting block is slidably installed in the slot, and the limiting block is provided with an adjusting rod for extending to the outside of the mounting box. The moving direction of the limiting block is the same as the moving direction of the support rod, and the bottom of the limiting block near the pressure block is inclined.

[0009] Preferably, a limiting plate and a driving component for driving the limiting plate to rotate and move toward the mounting plate are hinged to the inner top wall of the mounting box, and the driving component is controlled by a first touch switch.

[0010] Preferably, the limiting plate includes a support plate, on which a contact plate and a driving mechanism for driving the contact plate to slide are provided. The driving mechanism is controlled by a first touch switch, and the moving direction of the contact plate is the same as the moving direction of the support rod.

[0011] Preferably, the contact element includes a support, the support is provided with a telescopic element, and the movable end of the telescopic element is provided with a support block.

[0012] Preferably, the platform is equipped with a support assembly controlled by a first touch switch. Compared with the prior art, the beneficial effects of the present invention are: in this application, when the drive motor drives the clamping plate to rotate with the fixed assembly, if the output shaft of the drive motor bends, the contact element will be pressed downward, causing the support rod to move downward with the pressing element, pressing the first touch switch, stopping the drive motor, and simultaneously triggering an alarm to alert the staff, ensuring that the staff can promptly understand the abnormal situation and take action, reducing the probability of safety hazards.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1

[0021] Please see Figure 1 An assembly table for assembling marine diesel engines is disclosed. The assembly fixture includes a robotic arm 2 and a tilting assembly 3 (other assembly equipment can also be added). The assembly table includes a platform 1, on which the robotic arm 2 and the tilting assembly 3 are mounted. The tilting assembly 3 includes a drive motor and two clamping plates mounted on the output shaft of the drive motor. The two drive motors are slidably mounted on the platform 1 and slide on the platform 1 to change the distance between the two clamping plates. When the workpiece to be assembled is between the two clamping plates (the workpiece to be assembled can be a part of the structure of the diesel engine), the two clamping plates are brought together by moving the drive motors to clamp the workpiece. The drive motors then operate to drive the clamping plates to rotate, which can rotate the workpiece to change its angle. The robotic arm can be used to clamp, move, and position the workpiece required during the assembly process.

[0022] Please see Figure 1 , Figure 2 and Figure 3A mounting box 4 is installed on the platform 1. A support rod 6 is slidably inserted into the top of the inner cavity of the mounting box 4. A contact 7 is provided at the top of the support rod 6, and the contact 7 is in contact with the output shaft of the drive motor. A pressing part 8 is provided at the bottom of the support rod 6. An elastic part 9 (spring) is provided between the pressing part 8 and the mounting box 4. A first touch switch 5 is installed in the inner cavity of the mounting box 4. The first touch switch 5 is located below the pressing part 8, and the first touch switch 5 can control the flip assembly 3 to cut off the power. A warning device (alarm) is installed on the mounting box 4. The first touch switch 5, the power supply (battery) and the warning device are connected in series.

[0023] It should be noted that the mounting box 4 is slidably mounted on the platform 1. The moving direction of the mounting box 4 is the same as the moving direction of the drive motor. Furthermore, a connecting piece is installed between the mounting box 4 and the drive motor, so that the drive motor can move the mounting box 4 together with it when it moves.

[0024] It should also be noted that the contact area between the contact element 7 and the output shaft of the drive motor is equipped with a ball bearing; the ball bearing contacts the output shaft of the drive motor to reduce the friction between the output shaft of the drive motor and the contact element 7 when the output shaft of the drive motor rotates.

[0025] Working principle: When the drive motor drives the clamping plate to rotate with the fixed workpiece, if the output shaft of the drive motor is bent, the contact 7 will be pressed downward (because the radius of the output shaft's rotation trajectory increases after the drive motor's output shaft is bent), causing the support rod 6 to move downward with the pressing part 8, pressing the first touch switch 5, stopping the drive motor, and simultaneously triggering an alarm to alert the staff, ensuring that the staff can promptly understand the abnormal situation and handle it; conversely, if the output shaft of the drive motor is normal, the contact 7 will not move, indicating that the flipping assembly 3 is normal; by installing detection equipment on the assembly platform 1, the assembly fixture (flipping assembly) is detected, increasing the functionality of the assembly platform and improving the safety during the assembly process.

[0026] It should be noted that guide blocks (triangular in shape, such as...) are installed on both the front and rear sides of the top of the contact element 7. Figure 3 As shown), it is used to guide the output shaft of the flip assembly 3 into the upper part of the contact 7, so as to avoid the output shaft of the flip assembly 3 directly contacting the side wall of the contact 7 and causing the contact 7 to be unable to move down (when the output shaft of the flip assembly 3 has a large bending range, the output shaft of the flip assembly 3 is prone to contacting the side wall of the contact 7 when rotating), so as to ensure the accuracy of detection.

[0027] It should also be noted that before assembling the diesel engine, the drive motor can be run first to test the output shaft of the drive motor.

[0028] In this embodiment, as a further optimization, please refer to... Figure 3 and Figure 4 The pressing component 8 includes a mounting plate 81 (with an elastic element 9 connected to the mounting plate 81) installed at the bottom of the support rod 6. A guide block 83 is slidably inserted into the bottom of the mounting plate 81, and the movement direction of the guide block 83 is the same as that of the support rod 6. An electromagnet 84 is provided on the support rod 6, and the guide block 83 can be attracted by the magnetism of the electromagnet 84 (the guide block 83 is made of iron). A movable plate 82 is provided at the bottom end of the guide block 83. A mounting groove 811 is provided on the side wall of the mounting plate 81, and a second touch switch is provided in the mounting groove 811. The second touch switch, power supply and power supply are connected to the mounting plate 81. Magnets 84 are connected in series. A pressure block 812 is slidably inserted into the mounting groove 811. A push spring is installed between the pressure block 812 and the inner cavity of the mounting groove 811. The inner end of the pressure block 812 presses the second touch switch (to energize the electromagnet 84 and generate magnetic force to attract the guide block 83 and fix the movable plate 82). A slot 11 is opened on the inner wall of the mounting box 4. A limiting block 12 is provided in the slot 11. The side of the pressure block 812 away from the mounting plate 81 is in contact with the limiting block 12, and the bottom of the limiting block 12 is not in contact with the bottom of the inner cavity of the slot 11.

[0029] It should be noted that when the support rod 6 moves down with the pressing member 8, so that the pressing block 812 does not contact the limiting block 12 (the end of the pressing block 812 away from the mounting plate 81 faces the slot 11), the restriction on the pressing block 812 disappears; under the action of the push spring, the pressing block 812 moves into the slot 11, so that the pressing block 812 stops pressing the second touch switch, cuts off the power supply to the electromagnet 84, and makes the attraction force on the guide block 83 disappear; under the action of gravity, the movable plate 82 moves down to press the first touch switch 5; by the movable plate 82 moving down to press the first touch switch 5, the first touch switch 5 can work quickly when the output shaft of the drive motor bends, increasing the sensitivity of detection; and the movable plate 82 directly presses the first touch switch 5, instead of the mounting plate 81 squeezing the movable plate 82, so that it presses the first touch switch 5, which can reduce the pressure on the first touch switch 5.

[0030] In this embodiment, as a further optimization, please refer to... Figure 3 and Figure 4 The limiting block 12 is slidably installed in the slot 11. The limiting block 12 is provided with an adjusting rod 10. The end of the adjusting rod 10 away from the limiting block 12 extends to the outside of the mounting box 4. The moving direction of the limiting block 12 is the same as the moving direction of the support rod 6. Bolts are installed on the mounting box 4 to fix the adjusting rod 10. The bottom of the limiting block 12 near the pressure block 812 is a slope. By moving the adjusting rod 10, the height of the limiting block 12 is changed so that the moving timing of the movable plate 82 can be adjusted, thereby controlling the timing when the first touch switch 5 is triggered. The slope below the limiting block 12 ensures that the pressure block 812 is completely squeezed into the mounting slot 811 during the upward movement of the mounting plate 81, which is used to reset the movable plate 82.

[0031] In this embodiment, as a further optimization, please refer to... Figure 5 A limiting plate 13 is hinged to the inner top wall of the mounting box 4. A driving component 14 (which can be an electric telescopic rod) is provided on the inner wall of the mounting box 4. The driving component 14 is controlled by a first touch switch 5. When the first touch switch 5 is pressed, the driving component 14 works, pushing the limiting plate 13 toward the mounting plate 81, causing the limiting plate 13 to rotate and approach the mounting plate 81 and make contact, thus supporting the mounting plate 81 and preventing the mounting plate 81 from moving further down. This allows the contact component 7 to support the bent output shaft of the drive motor, reducing the probability of the output shaft of the drive motor continuing to bend.

[0032] In this embodiment, as a further optimization, please refer to... Figure 5 and Figure 6 The limiting plate 13 includes a support plate 131, on which a contact plate 132 is slidably provided. The moving direction of the contact plate 132 is the same as the moving direction of the support rod 6. A drive mechanism 133 (such as an electric telescopic rod) is installed on the support plate 131. The moving end of the drive mechanism 133 is connected to the contact plate 132. During the rotation of the limiting plate 13, the drive mechanism 133 is also controlled by the first touch switch 5 to make the contact plate 132 extend and contact the bottom of the inner cavity of the mounting box 4, so that the limiting plate 13 provides more stable support for the mounting plate 81.

[0033] In this embodiment, as a further optimization, please refer to... Figure 3 The contact 7 includes a support 71, on which a telescopic member 72 (such as an electric telescopic rod) is provided. A support block 73 is provided on the moving end of the telescopic member 72. By utilizing the telescopic member 72, the support block 73 can move up and down, changing the height of the support block 73, thereby adjusting the distance between the contact 7 and the output shaft of the drive motor.

[0034] Example 2

[0035] As a further optimization of Example 1, please refer to Figure 1 A support assembly 15 is installed on the platform 1;

[0036] The support assembly 15 includes a telescopic mechanism (such as an electric telescopic rod) mounted on the platform 1. A support plate is provided on the moving end of the telescopic mechanism. The telescopic mechanism is controlled by a first touch switch 5. When the first touch switch 5 is pressed, the telescopic mechanism is energized, causing the support plate to rise and support the fixed assembly workpiece, preventing it from falling and reducing the probability of safety hazards. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
