[0002] During the assembly of an automobile engine, the assembly precision of the cylinder liner and the cylinder block directly affects the engine's sealing performance, heat dissipation efficiency, and service life. Therefore, it is necessary to use specialized assembly equipment to accurately position and securely clamp the cylinder liner.

[0003] The prior art patent document CN218556166U discloses an assembly device for automobile engine cylinders. This utility model uses a lifting mechanism to move the worktable up and down, so that the worktable can be used by workers of different heights, increasing its practicality. At the same time, it is equipped with a shock-absorbing component, which can play a role in damping vibration during the assembly process, preventing excessive vibration of the engine cylinder and damage. Furthermore, the engine cylinder can be clamped and fixed by the cooperation of the clamping mechanism and the clamping mechanism, eliminating the need for manual fixing, thus improving the operation efficiency and reducing labor costs.

[0004] The clamping cylinders in existing automotive engine cylinder liner assembly equipment are mostly fixedly installed. While this can meet basic clamping requirements for a single model or specification of cylinder liner, it has significant limitations in actual production. This is because automotive engines come in a variety of models, and cylinder liners for different models vary, making it inconvenient to adjust the position of the clamping cylinder according to the specific automotive engine cylinder liner.

[0020] Please see Figures 1-4 This utility model provides a technical solution: an automotive engine cylinder assembly device, including a workbench 1, support rods 2 fixedly installed at the four corners of the top of the workbench 1, an mounting plate 3 fixedly installed at the top of the support rods 2, a through groove 4 opened in the middle of the mounting plate 3, a nut seat 5 movably installed at the inner end of the through groove 4, an mounting frame 6 fixedly installed at the bottom end of the nut seat 5, a nut seat 7 movably installed at the inner end of the mounting frame 6, a connecting plate 8 fixedly installed at the bottom end of the nut seat 7, a connecting plate 9 fixedly installed on one side of the connecting plate 8, a CCD sensor 10 fixedly installed at the bottom end of the connecting plate 9, a clamping cylinder 11 fixedly installed at the bottom end of the connecting plate 8, and a top plate 12 fixedly installed at the transmission end of the clamping cylinder 11.

[0021] like Figures 1-4As shown, a geared motor 13 is fixedly mounted on one side of the mounting plate 3. The output shaft of the geared motor 13 extends into the interior of the through groove 4. A lead screw 14 is fixedly mounted on the output shaft of the geared motor 13, passing through a nut seat 5 and threadedly connected to the nut seat 5. A geared motor 25 is fixedly mounted on one side of the mounting frame 6. The output shaft of the geared motor 25 extends into the interior of the mounting frame 6. A lead screw 26 is fixedly mounted on the output shaft of the geared motor 25, passing through a nut seat 27 and threadedly connected to the nut seat 27. Slide grooves 17 are provided on both sides of the inner end of the mounting plate 3. A slider 18 is movably mounted on the inner end of the slide groove 17. The sliders 18 are located on both sides of the top of the mounting frame 6 and are fixedly connected to the mounting frame. 6. A placement seat 19 is fixedly installed at the top of the workbench 1. An installation groove 20 is opened at the inner end of the placement seat 19. A geared motor 21 is fixedly installed on one side of the placement seat 19. The output shaft of the geared motor 21 extends into the interior of the installation groove 20. A double-acting lead screw 22 is fixedly installed at the output shaft of the geared motor 21. A nut seat 23 is threaded on the outer end of the double-acting lead screw 22. A clamping plate 24 is fixedly installed at the top of the nut seat 23. Fixing plates 25 are fixedly installed on both sides of the top of the placement seat 19. An electric push rod 26 is fixedly installed in the middle of the fixing plate 25.

[0022] Working principle: When using the automotive engine cylinder assembly equipment, the operator places the automotive engine cylinder on the mounting seat 19. The reduction motor 21 drives the double-acting lead screw 22 to rotate. The threads on both sides of the double-acting lead screw 22 are in opposite directions, which can simultaneously drive the nut seats 23 on both sides to move towards each other. The nut seats 23 drive the clamping plate 24 to move towards the center at the same time, clamping and fixing the two sides of the automotive engine cylinder. The electric push rod 26 pushes the clamping plate 27 to clamp and fix the other two sides of the automotive engine cylinder. The clamping plates 24 and 27 work together to clamp and fix the automotive engine cylinder around its perimeter, preventing excessive pressure. During the process, the car engine cylinder shifts. Under the action of CCD sensor 10, the reference hole or plane on the top surface of the car engine cylinder is identified. The reduction motor 13 drives the lead screw 14 to rotate, which drives the mounting frame 6 and the clamping cylinder 11 to move back and forth through the nut seat 15. The slide groove 17 and the slider 18 can improve the stability of the movement of the mounting frame 6. The reduction motor 2 15 drives the lead screw 2 16 to rotate, which drives the clamping cylinder 11 to move left and right through the nut seat 2 7, ensuring that the clamping force acts vertically on the top surface of the car engine cylinder and avoids excessive local force. The clamping cylinder 11 pushes the top plate 12 to move downward to clamp the car engine cylinder.

[0023] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
