The clamping plate is rotatably connected to one end of the connecting rod, while the other end of the connecting rod is rotatably connected to the movable plate. When the pallet moves relative to the movable plate, the transmission action of the connecting rod can provide a basic force for the movement of the clamping plate, thereby ensuring the basic clamping and fixing of the front axle body and ensuring the stability of the subsequent processing of the front axle body.
[0008] Preferably, a first camera is fixed on the bracket, and two first cameras are symmetrically arranged in front and behind. Through the function of the first camera, the detection and positioning of the front axle body can be realized, ensuring the normal processing of the front axle body.

The movable frame and the round rod fixed on the bracket are slidably connected. The above structure can provide a basic guarantee for realizing the left and right position adjustment of the assembly mechanism.
[0010] Preferably, a drive motor is fixed on the movable frame, and the drive motor and the threaded rod connected to the bearing on the movable frame are fixed to each other.

[0025] 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.
[0026] Please see Figures 1-6 The present invention provides a technical solution: a tractor front axle assembly line device, including a support frame 1, a conveying mechanism 2 and a front axle body 3. The support frame 1 is equipped with a conveying mechanism 2 for conveying the front axle body 3. A positioning mechanism 4 is fixed on the support frame 1. A bracket 5 is also fixed on the support frame 1. An adjustment mechanism 7 is connected to the bracket 5. The adjustment mechanism 7 is interconnected with the assembly mechanism 8.
[0027] The positioning mechanism 4 includes a first cylinder 401 fixed on the support frame 1, and a movable plate 402 fixed to the output end of the first cylinder 401. A support plate 403 is provided above the movable plate 402, and a vertical rod 404 is fixed to the lower end of the support plate 403. The vertical rod 404 and the movable plate 402 are slidably connected, and a first spring 405 is fixed between the movable plate 402 and the support plate 403. A horizontal rod 406 is symmetrically fixed on the support plate 403, and a clamping plate 407 is slidably connected to the horizontal rod 406. One end of the clamping plate 407 is rotatably connected to a connecting rod 408, and the other end of the connecting rod 408 is rotatably connected to the movable plate 402. A first camera 6 is fixed on the bracket 5, and two first cameras 6 are symmetrically arranged in front and behind.
[0028] When using this tractor front axle assembly line unit, such as Figures 1-6 As shown, the front axle body 3 is moved from left to right by the conveying mechanism 2. The position of the front axle body 3 can be monitored by the first camera 6. When the front axle body 3 moves to engage with the positioning mechanism 4, the conveying mechanism 2 stops operating, and the first cylinder 401 extends. The extension of the first cylinder 401 drives the movable plate 402 and the support plate 403 to move. When the support plate 403 contacts the front axle body 3, the support plate 403 is limited to continue moving under the weight of the front axle body 3, while the first cylinder 401 continues to extend. The distance between the movable plate 402 and the support plate 403, combined with the sliding guide effect between the vertical rod 404 and the movable plate 402, ensures the stability of the movement of the support plate 403 relative to the movable plate 402. At this time, in conjunction with the action of the connecting rod 408, the clamping plate 407 is subjected to force and slides on the horizontal rod 406, thereby reducing the distance between the two clamping plates 407 until the clamping plate 407 contacts the front axle body 3 to achieve clamping and limiting of the front axle body 3, ensuring the stability of the front axle body 3, so as to facilitate the subsequent processing of the front axle body 3;
[0029] The adjusting mechanism 7 includes a hydraulic rod 701 fixed on the bracket 5, and the output end of the hydraulic rod 701 is fixed to the movable frame 702. The movable frame 702 is slidably connected to the round rod 703 fixed on the bracket 5. A drive motor 704 is fixed on the movable frame 702, and the drive motor 704 is fixed to the threaded rod 705 which is connected to the movable frame 702 by a bearing. The threaded rod 705 is connected to the slider 706 by a bearing. The slider 706 is slidably connected to the guide rod 707, and the guide rod 707 is fixed on the movable frame 702. A second cylinder 708 is fixed to the lower end of the slider 706.
[0030] After the front axle body 3 is limited, as follows Figures 1-6 As shown, the robotic arm engages the components to be assembled with the front axle body 3, and then the assembly mechanism 8 performs the assembly operation. During the assembly process, the hydraulic rod 701 extends and retracts, which allows the movable frame 702 to move left and right, thereby adjusting the left and right position of the assembly mechanism 8. In conjunction with the drive motor 704 driving the threaded rod 705 to rotate, the slider 706 is moved under force, thereby adjusting the front and rear position of the assembly mechanism 8. In conjunction with the second cylinder 708, the height of the assembly mechanism 8 can be adjusted to meet the assembly requirements of different parts.
[0031] The assembly mechanism 8 includes a mounting plate 801 fixed to the output end of the second cylinder 708. A slide rod 804 is slidably connected to the mounting plate 801, and a pressure plate 807 is fixed to the slide rod 804. The pressure plate 807 is located directly below the control switch 808, which is fixed to the lower end face of the mounting plate 801. A servo motor 809 is fixed to the lower end of the slide rod 804, and a disc 810 is fixed to the output end of the servo motor 809. An electromagnet 811 is fixed to the upper inner side of the disc 810, and the electromagnet 811 is electrically connected to the control switch 808. An austenitic stainless steel rod 812 is slidably connected to the disc 810, and an iron block 813 is fixed to the austenitic stainless steel rod 812. The iron block 813 and the electromagnet 811 form a magnetic attraction structure. A locking device is fixed to the lower end of the austenitic stainless steel rod 812. A second camera 818 is fixed to the lower end face of a sleeve 814 and a disc 810; an electric air gun 802 is fixed to the lower end face of a mounting plate 801, and a connecting sleeve 803 is fixed to the output end of the electric air gun 802, and a flared slot is provided on the connecting sleeve 803; a second spring 805 is fixed between a slide rod 804 and a mounting plate 801, and the slide rod 804 contacts a limiting plate 806 to achieve a positioning function, and the limiting plate 806 is fixed to a second cylinder 708; a circular plate 815 is fixed to the upper end of an austenitic stainless steel rod 812, and a connecting rod 816 is fixed to the upper end of the circular plate 815, and the connecting rod 816 and the connecting sleeve 803 are nested together, and a convex shaft 817 is also fixed to the connecting rod 816, and the convex shaft 817 and the flared slot on the connecting sleeve 803 are slidably connected;
[0032] When locking the components on the front axle body 3, such as Figures 1-6As shown, the second camera 818 can determine the position to be locked. The adjustment mechanism 7 can be used to adjust the position of the electric air gun 802 so that it is directly above the locking position. At this time, the second spring 805 is in a contracted state. After adjustment, the size of the locking bolt is determined based on the data captured by the second camera 818. The servo motor 809 drives the disc 810 to rotate, thereby rotating multiple locking sleeves 814. This allows for the replacement of different locking sleeves 814, ensuring that the locking sleeves 814 can match the size of the locking bolt. After adjustment, during assembly and locking, the second cylinder 708 extends, causing the mounting plate 801 to move downwards, thereby moving the electric air gun 802 and the connecting sleeve 805. 03. As the second spring 805 moves downward, the slide bar 804, servo motor 809, and disc 810 move upward relative to the mounting plate 801, thus reducing the distance between the connecting sleeve 803 and the disc 810. When the flared slot on the connecting sleeve 803 contacts and slides against the convex shaft 817, the sleeve rod 816 can rotate under force, allowing the sleeve rod 816 and the connecting sleeve 803 to accurately nest and fit together. When the sleeve rod 816 and the connecting sleeve 803 are nested, the pressure plate 807 is in contact with the control switch 808, causing the control switch 808 to activate the electromagnet 811. Since the austenitic stainless steel rod 812 is not magnetic, the magnetic attraction between the electromagnet 811 and the iron block 813 causes the un-magnetized rod 812 to move upward. The locking sleeve 814, which mates with the connecting sleeve 803, moves upward under force and enters the disc 810, thus achieving the automatic retraction and avoidance function of the locking sleeve 814. This prevents the locking sleeve 814, which does not mate with the connecting sleeve 803, from obstructing the normal operation of the device. At this time, due to the contact positioning function of the pressure plate 807 and the control switch 808, when the second cylinder 708 continues to extend, it can drive the electric air gun 802, the connecting sleeve 803, the disc 810, and the locking sleeve 814 to move downward synchronously until the locking sleeve 814 mates with the connecting sleeve 803 engages with the locking bolt. Finally, the electric air gun 802 drives the connecting sleeve 803 and the locking sleeve 814 mates with the connecting sleeve 803 to rotate, thereby achieving the locking effect of the locking bolt and realizing the connection between the components and the front axle. The assembly process between the three bodies involves the following: when the locking sleeve 814 needs to be replaced, the second cylinder 708 is controlled to retract. When the slide rod 804 contacts the limit plate 806, the slide rod 804 is forced to move downward relative to the mounting plate 801, thereby separating the pressure plate 807 from the control switch 808 and turning off the electromagnet 811. Through the weight of the locking sleeve 814 itself, the locking sleeve 814 that has entered the disc 810 automatically moves downward and resets. Based on the above principle, the disc 810 is rotated by the servo motor 809, which can realize the replacement of locking sleeves 814 of different sizes to better meet the actual assembly needs. Compared with traditional manual assembly, it can effectively improve processing efficiency. This is the working principle of the tractor front axle assembly line device.
