Description

Technical Field

[0001] The present invention specifically relates to the technical field of engine assembly, specifically an engine block assembly system. Background Art

[0002] The engine block is an important part of the engine and is the skeleton of the engine. It organically combines various components of the engine to form an integral structure, providing a mounting position and support for other components. And the assembly of the engine block is a complex and delicate task. The assembly of the engine block includes structures such as the crankshaft, piston rod, and cylinder head. Due to the relatively complex structure, manual assembly is generally used for assembly.

[0003] However, in practice, it has been noted that in the manual assembly process, assembly line operations are generally adopted. The body is fixed on the transportation tooling and moves along the ground rail transportation line. Workers follow the movement of the body and place the fittings at the designated positions of the collective. This way of operating while walking has relatively large potential safety hazards. Therefore, robots are used to replace manual operations in some steps. And during the assembly process, the body needs to be flipped and tilted. During the tilting process, the tooling will lose balance, resulting in the dumping of the tooling and the body, and it is easy to cause safety accidents, with relatively low safety. Summary of the Invention

[0004] The purpose of the present invention is to provide an engine block assembly system. By jacking up with a cylinder to tilt one side of the body fixing frame, and using a sliding structure to adjust the lateral position of the other end of the fixing frame, ensuring that the center of gravity of the tooling is always located in the middle position to prevent the tooling from losing balance. To solve the technical problems proposed in the above background art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An engine block assembly system includes a vertically distributed longitudinal ground rail transportation line and a transverse ground rail transportation line. On both sides of the longitudinal ground rail transportation line, a parts assembly robot and an auxiliary robot are respectively provided;

[0007] A moving tooling is placed above the longitudinal ground rail transportation line. The moving tooling includes a rectangular frame.

And a body gripper that is movably connected to the transverse adjusting frame is further provided above the rectangular frame;

[0008] Among them, the transverse adjusting frame includes symmetrically fixedly connected support ear plates. A threaded lead screw is movably connected between the symmetrically arranged support ear plates. A threaded hole slider is movably connected to the outside of the threaded lead screw. A triangular bracket is integrally provided above the threaded hole slider.

[0009] As a further technical solution of the present invention, a servo motor fixedly connected to the rectangular frame is provided at each end of the transverse adjustment frame, and the end of the servo motor is in transmission cooperation with a threaded lead screw, and the threaded hole slider is in threaded cooperation with the threaded lead screw.

[0010] As a further technical solution of the present invention, the body holder includes an outer frame, threaded sleeves are symmetrically and fixedly connected to both sides of the outer frame, a threaded ejector rod is in threaded cooperation with each of the threaded sleeves, and a threaded hole slider is integrally provided at one end of the threaded ejector rod away from the threaded sleeve.

[0011] As a further technical solution of the present invention, rectangular sliding sleeves are symmetrically and slidably fitted to both sides of the outer frame, and a locking bolt is in threaded cooperation with the side surface of each of the rectangular sliding sleeves;

[0012] Side positioning rods are provided at both ends inside the outer frame, and both ends of the side positioning rods are fixedly connected to the rectangular sliding sleeves respectively.

[0014] As a further technical solution of the present invention, one end of the lifting electric cylinder is movably connected to the rectangular frame through a pin shaft, and the other end of the lifting electric cylinder is movably connected to the side of the outer frame away from the end shaft through a pin shaft.

[0015] As a further technical solution of the present invention, an engine body is placed inside the outer frame, the side positioning rods are respectively in contact with both ends of the engine body, and the clamping pads at the ends of the threaded ejector rods are in contact with the side surface of the engine body.

[0016] As a further technical solution of the present invention, a turntable is provided between the longitudinal ground rail transportation line and the transverse ground rail transportation line.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In the present invention, the lifting electric cylinder pushes the end of the body holder to turn upwards. At this time, the servo motor drives the threaded lead screw to rotate, and the transverse position of the threaded hole slider is adjusted through the threaded cooperation between the threaded lead screw and the threaded hole slider. Since the other end of the body holder is movably connected to the triangular bracket, while adjusting the inclination angle of the body holder, the position of the body holder on the rectangular frame will also be adjusted, which can ensure the balance of the mobile tooling, prevent the risk of the mobile tooling tipping over, and improve safety;

At this time, the part assembly robots and auxiliary robots on both sides of the longitudinal rail transportation line cooperate with each other to automatically assemble the engine block. Moreover, the part assembly robots and auxiliary robots have clear division of labor and can also cooperate with each other, thereby realizing automatic assembly. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-2 、 Figure 5-6 , the engine block assembly system provided by the embodiment of the present invention includes a longitudinal rail transportation line 1 and a transverse rail transportation line 7 that are vertically distributed. On both sides of the longitudinal rail transportation line 1, there are respectively a parts assembly robot 2 and an auxiliary robot 3;

[0032] Above the longitudinal rail transportation line 1, there is a mobile tooling 4. The mobile tooling 4 includes a rectangular frame 41. At both ends of the rectangular frame 41, there are installed lateral adjustment frames 42. Above the rectangular frame 41, there is also a body gripper 43 that is movably connected to the lateral adjustment frame 42;

[0033] Among them, the lateral adjustment frame 42 includes symmetrically fixedly connected support ear plates 422. Between the symmetrically arranged support ear plates 422, there is a movably connected threaded lead screw 421. On the outer side of the threaded lead screw 421, there is a movably connected threaded hole slider 423. Above the threaded hole slider 423, there is an integrally formed triangular bracket 424.

[0034] Furthermore, at the end of each lateral adjustment frame 42, there is a servo motor 45 fixedly connected to the rectangular frame 41. And the end of the servo motor 45 is in transmission cooperation with the threaded lead screw 421. The threaded hole slider 423 is in threaded cooperation with the threaded lead screw 421.

[0035] By adopting the above technical solution, the lifting electric cylinder 44 pushes the end of the body gripper 43 to turn upward. At this time, the servo motor 45 drives the threaded lead screw 421 to rotate, and adjusts the lateral position of the threaded hole slider 423 through the threaded fit between the threaded lead screw 421 and the threaded hole slider 423. Since the other end of the body gripper 43 is movably connected to the triangular bracket 424, while adjusting the inclination angle of the body gripper 43, the position of the body gripper 43 on the rectangular frame 41 will also be adjusted, which can ensure the balance of the moving tooling 4, prevent the risk of the moving tooling 4 tipping over, and improve safety.

[0036] Please refer to Figure 3-4 、 Figure 7 Furthermore, the body gripper 43 includes an outer frame 434. Threaded sleeves 431 are symmetrically and fixedly connected to both sides of the outer frame 434. A threaded ejector rod 432 is in threaded fit in each of the threaded sleeves 431, and a threaded hole slider 423 is integrally provided at the end of the threaded ejector rod 432 away from the threaded sleeve 431.

[0037] Specifically, rectangular sliding sleeves 435 are symmetrically and slidably fitted on both sides of the outer frame 434, and a locking bolt is in threaded fit on the side of each of the rectangular sliding sleeves 435;

[0038] Lateral positioning rods 436 are provided at both ends inside the outer frame 434, and both ends of the lateral positioning rods 436 are fixedly connected to the rectangular sliding sleeves 435 respectively.

[0039] Furthermore, end shafts 437 are symmetrically and fixedly connected to both ends on one side of the outer frame 434. The end shafts 437 are movably connected to the triangular bracket 424 through bearings, and lifting electric cylinders 44 are symmetrically provided below the outer frame 434.

[0040] Furthermore, one end of the lifting electric cylinder 44 is movably connected to the rectangular frame 41 through a pin shaft, and the other end of the lifting electric cylinder 44 is movably connected to the side of the outer frame 434 away from the end shaft 437 through a pin shaft.

[0041] Specifically, an engine block 5 is also placed inside the outer frame 434, and the lateral positioning rods 436 are respectively in contact with both ends of the engine block 5, while the clamping pads 433 at the ends of the threaded ejector rods 432 are in contact with the side of the engine block 5.

[0042] By adopting the above technical solution, the engine block 5 is placed inside the outer frame 434. Through the rectangular sliding sleeve 435 slidably fitted on the outer frame 434, the relative position between the side positioning rod 436 and the engine block 5 is adjusted, and both ends of the engine block 5 are clamped. Then, a wrench is clamped outside the clamping pad 433, and the clamping pad 433 is used to rotate the threaded ejector rod 432. Through the threaded fit between the threaded ejector rod 432 and the threaded sleeve 431, the end of the threaded ejector rod 432 is made to fit against the side surface of the engine block 5, facilitating the clamping and fixing of the side surface of the engine block 5. The engine block 5 is quickly and firmly clamped through multiple clamping points.

[0043] Further, a turntable 6 is provided between the longitudinal ground rail transportation line 1 and the transverse ground rail transportation line 7.

[0044] Specifically, the clamping pad 433 is integrally cylindrical, and both sides of the clamping pad 433 are provided with planes for cooperating with the wrench. The wrench is clamped and fitted with the planes on both sides of the clamping pad 433, and the wrench is used to rotate the clamping pad 433.

[0045] Further, a plurality of part assembly robots 2 and auxiliary robots 3 are provided, and parts supporting the engine block 5 can be placed between two part assembly robots 2 or auxiliary robots 3.

[0046] Further, the turntable 6 includes a platform for support and a rotatable rotating frame, and the platform and the rotating frame are rotatably fitted. A hydraulic cylinder is also installed in the platform, and the end of the hydraulic cylinder contacts the rotating frame;

[0047] When the moving tooling 4 moves above the rotating frame, the lifting cylinder jacks up the rotating frame. Then, the rotating motor in the platform drives the rotating frame to rotate through the transmission cooperation with the rotating frame. Finally, the rotating frame descends to place the end of the moving tooling 4 at the end of the transverse ground rail transportation line 7.

[0048] The working principle of the present invention is as follows: When in use, first place the engine block 5 into the outer frame 434. Then, through the sliding fit between the rectangular sliding sleeve 435 and the outer frame 434, adjust the position of the side positioning rod 436 so that the side positioning rods 436 are distributed at both ends of the engine block 5. Then, clamp the wrench onto the outside of the clamping pad 433, and then rotate the threaded ejector rod 432 through the clamping pad 433. Through the threaded fit between the threaded ejector rod 432 and the threaded sleeve 431, make the clamping pad 433 at the end of the threaded ejector rod 432 press tightly against both sides of the engine block 5. Then, place the entire mobile tooling 4 onto the longitudinal rail transportation line 1. The longitudinal rail transportation line 1 drives the mobile tooling 4 and the engine block 5 to move. At this time, the two side part assembly robots 2 and the auxiliary robot 3 cooperate with each other to assemble the engine parts onto the engine block 5. When the mobile tooling 4 moves above the rotating frame, the lifting cylinder lifts the rotating frame. Then, the rotating motor in the platform drives the rotating frame to rotate through the transmission fit with the rotating frame. Finally, the rotating frame descends and places the end of the mobile tooling 4 onto the end of the transverse rail transportation line 7;

[0049] When the engine block 5 needs to be tilted during the installation process, the lifting electric cylinder 44 pushes one side of the outer frame 434 upward. Since one side of the outer frame 434 is movably connected to the triangular bracket 424 through the end shaft rod 437, in cooperation with the lifting electric cylinder 44, the outer frame 434 is set to be tilted. During the tilting process, the center of gravity of the mobile tooling 4 will shift. At this time, the servo motor 45 can drive the threaded lead screw 421 to rotate. Through the threaded fit between the threaded lead screw 421 and the threaded hole slider 423, the horizontal position of the body gripper 43 above the rectangular frame 41 can be adjusted, thereby ensuring the stability of the center of the mobile tooling 4 and preventing the mobile tooling 4 from tipping over, thus improving the stability during the assembly process; the structure is simple, the operation is very convenient, and the manual labor intensity is effectively reduced.
