Any limited number of modifications made by anyone within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0026] The specific embodiment of the present invention is as follows: Figure 1-4 As shown, a device for realizing 360-degree arbitrary flipping of engine assembly includes a mounting seat 1, a linear slide rail 2 is provided at the front end of the mounting seat 1, two relatively arranged clamping seats 3 are slidably provided on the linear slide rail 2, a push-pull device 4 is provided between the two clamping seats 3, a rotatable manipulator device 5 is provided on the inner sides of the two clamping seats 3, and a flipping drive device 6 and a return rotation device 7 for driving the manipulator device 5 are respectively provided on the outer sides of the two clamping seats 3.

[0027] In the present device for realizing 360-degree arbitrary flipping of engine assembly, two clamping seats 3 are arranged opposite to each other, and two manipulator devices 5 are respectively installed on the inner sides of the two clamping seats 3 and can rotate 360 ​​degrees. The push-pull device 4 can drive the two clamping seats 3 to slide relative to or away from each other along the linear slide rail 2; when driving the two clamping seats 3 to slide relative to each other, the manipulator devices 5 on the two clamping seats 3 can clamp the workpiece, and then the manipulator device 5 on one of the clamping seats 3 is driven to rotate through the flipping drive device 6 on the clamping seat 3, and at the same time, the manipulator device 5 on the other clamping seat is driven to rotate through the workpiece. The flipping drive device 6 can accurately control the rotation angle of the manipulator device 5 to meet the assembly requirements, and can quickly adjust the position of the workpiece, with high work efficiency and low labor intensity of the staff, so as to realize automatic adjustment of the assembly posture of the engine cylinder head.

[0028] In the present invention, the 360-degree arbitrary turning device for engine assembly can be used to loosen the workpiece after the workpiece is assembled, that is, the manipulator device 5 on the two clamping seats 3 releases the workpiece, and the two clamping seats 3 are opened to remove the workpiece. Figure 1 As shown, the flip driving device 6 located on the left clamping seat 3 can control the rotation and reset of the manipulator device 5 on the clamping seat 3, and the return rotation device 7 located on the right clamping seat 3 can control the rotation and reset of the manipulator device 5 on the clamping seat 3, thereby realizing the reset of the two manipulator devices 5 to prepare for clamping the next workpiece.

[0029] The present invention realizes the 360-degree arbitrary turning device of the engine assembly, and does not need to set two sets of turning drive devices 6 on the two clamping seats, thus saving costs, reducing the structure setting and the weight of the device, and reducing the space occupied.

[0030] In this embodiment, the flip driving device 6 includes a servo motor 8 disposed on one of the clamping seats 3, a reducer 9, a manipulator rotating shaft 10 connected to the manipulator device 5, and a conveyor belt assembly 11 disposed between the reducer 9 and the manipulator rotating shaft 10. After the servo motor 8 is decelerated by the reducer 9, the torque is transmitted to the conveyor belt assembly 11, the conveyor belt assembly 11 drives the manipulator rotating shaft 10 to rotate, and the manipulator rotating shaft 10 drives the manipulator device 5 to rotate.

[0031] In this embodiment, the return rotation device 7 includes a rotating cylinder 12 arranged on another clamping seat 3, a cylinder rotating shaft 13, a manipulator rotating shaft 10 and a conveyor belt assembly 11 arranged between the cylinder rotating shaft 13 and the manipulator rotating shaft 10. When the rotating cylinder 12 in the return rotation device 7 is working, the cylinder rotating shaft 13 can be driven to rotate by air pressure, and the cylinder rotating shaft 13 can drive the manipulator rotating shaft 10 to rotate through the conveyor belt assembly 11, thereby driving the manipulator device 5 to reset through the manipulator rotating shaft 10.

[0032] In this embodiment, the reducer 9 is a worm gear reducer, the conveyor belt assembly 11 includes two pulleys 14, a conveyor belt 15 and a protective cover 16, and the worm gear reducer has an anti-locking function. The worm gear reducer can prevent the manipulator device 5 from being subjected to the reaction force of the external structure and the manipulator rotating shaft 10 from reversing, thereby ensuring the stable rotation of the manipulator device 5 and ensuring the accuracy of the rotation angle of the manipulator device 5.

[0033] In this embodiment, a cylinder bracket 17 for mounting the rotating cylinder 12 is provided on the outer side of the clamping seat 3, and a cylinder rotating shaft bearing assembly 18 is provided on the cylinder bracket 17. The cylinder rotating shaft bearing assembly 18 supports the cylinder rotating shaft 13 to ensure stable rotation of the cylinder rotating shaft 13.

[0034] In this embodiment, the manipulator device 5 includes a rotating plate 19 disposed at the inner end of the manipulator rotating shaft 10, a lower clamping plate 20 is disposed at the bottom of the rotating plate 19, a clamping cylinder 21 is disposed at the top of the rotating plate 19, and an upper clamping plate 22 adapted to the lower clamping plate 20 is disposed at the bottom of the push rod of the clamping cylinder 21. When the two clamping seats 3 are retracted, the lower clamping plate 20 at the bottom of the rotating plate 19 will support the workpiece between the two clamping seats 3, and the two clamping seats 3 continue to retract, and the two rotating plates 19 position the two sides of the workpiece, and then the clamping cylinder 21 drives the upper clamping plate 22 to press against the top surface of the workpiece, thereby clamping the workpiece.

[0035] In this embodiment, a rotating block 23 is provided on the outer end surface of the rotary plate 19, a sensor 24 is provided on the rotating block 23, a rotating gear cylinder 25 is provided on the outer side of the clamping seat 3, a push rod of the rotating gear cylinder 25 is provided through both sides of the clamping seat 3, a movable block 26 that can adapt to the rotating block 23 is provided on the push rod of the rotating gear cylinder 25, and a floating joint 27 is provided on the push rod of the rotating gear cylinder 25. The floating joint 27 can prevent the movable block 26 from causing a strong impact on the push rod of the rotating gear cylinder 25 when colliding with the rotating block 23, and prevent the rotating gear cylinder 25 from being damaged by a large impact, and the floating joint 27 has a buffering effect.

[0036] After the sensor 24 contacts the movable stopper 26, a control signal is sent to a control device such as a controller of the entire device or a control computer, thereby controlling the manipulator device 5 to stop rotating.

[0037] In this embodiment, angular contact bearings 28 matching with the two ends of the manipulator rotary shaft 10 are provided on both sides of the clamping seat 3 .

[0038] In this embodiment, the push-pull device 4 includes a push-pull cylinder 29 connecting two clamping seats 3, and the clamping seat 3 is provided with a slide seat 30 adapted to the linear slide rail 2. The push rod of the push-pull cylinder 29 is connected to the clamping seat 3 on the left, and the cylinder body of the push-pull cylinder 29 is connected to the clamping seat 3 on the right.

[0039] In this embodiment, a screw rod 31 is provided in the clamping seat 3 and passes through its front and rear ends. The front end of the clamping seat 3 is provided with a hand-cranked wheel 32 connected to the front end of the screw rod 31. The rear end of the screw rod 31 is located behind the clamping seat 3 and is provided with an eccentric block 33. The eccentric block 33 is a cubic structure, and a positioning seat 34 adapted to the eccentric block 33 is provided on the front end surface of the mounting seat 1.

[0040] After the clamping seat 3 slides inward to a certain position, the eccentric block 33 will collide with the positioning seat 34. At this time, it proves that the rotating plates 19 on the two clamping seats 3 just clamp the workpiece. The eccentric block 33 and the positioning seat 34 can limit the sliding position of the clamping seat 3 and the retraction distance of the push rod of the push-pull cylinder 29. A travel switch can be set on the positioning seat 34 to control the push-pull cylinder 29 to stop working.

[0041] In this embodiment, the eccentric block 33 is provided with an eccentric hole connected to the screw rod 31, and the distances between the circular shape of the eccentric hole and each side of the eccentric block 33 are different. The screw rod 31 can be rotated to drive the eccentric block 33 to rotate a certain angle, so that the distance between the inner side of the eccentric block 33 and the eccentric hole changes. According to the length of different workpieces, the minimum distance between the two clamping seats 3 can be controlled by rotating the eccentric block 33, which is suitable for clamping different types of cylinder head workpieces and has good adaptability.

[0042] In this embodiment, a limiting cylinder 35 is provided on one side of the mounting seat 1, and the push rod of the limiting cylinder 35 can be extended to the front of the mounting seat 1. The rear end of the clamping seat 3 is provided with a shock absorber 36 that can adapt to the push rod of the limiting cylinder 35. When the two clamping seats 3 are retracted, the shock absorber 36 on one of the clamping seats 3 will collide with the push rod on the limiting cylinder 35, thereby limiting the position of the clamping seat 3. Moreover, the shock absorber 36 is a telescopic rod mechanism, which has a shock-absorbing effect when colliding with the push rod on the limiting cylinder 35, and will not cause a large impact force.

[0043] In this embodiment, a connecting seat 37 is provided at the rear end of the mounting seat 1. A slot 38 which is narrow outside and wide inside is provided on the connecting seat 37. The mounting seat 1 can be quickly connected to the external structure through the slot 38 on the connecting seat 37 for easy assembly.

[0044] The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
