[0029] See also Figure 1-Figure 4 The embodiment of the utility model discloses an engine connecting rod transplanting manipulator unit, including a frame 1, a transplanting support frame 2, an X-direction transplanting assembly 3, a Z-direction transplanting assembly 4 and a clamping mechanism 5.

The clamping mechanism 5 includes a cylinder 51 and a clamp, the cylinder 51 is arranged at the transplanting end 7 of the Z-direction transplanting assembly 4, the clamp is two symmetrically arranged clamping arms 52, and the cylinder 51 adjusts the distance between the two clamping arms 52 to clamp engine connecting rod workpieces of different specifications.
[0030] When the engine connecting rod workpiece needs to be clamped, the engine connecting rod transfer manipulator unit first starts the X-direction transfer assembly 3 and the Z-direction transfer assembly 4 to move according to the position information of the engine connecting rod workpiece, so that the clamping arm 52 moves in the horizontal direction and the vertical direction to align with the engine connecting rod workpiece, and finally the cylinder 51 works, and the cylinder 51 drives the two symmetrically arranged clamping arms 52 to approach each other to clamp the engine connecting rod workpiece.

When the X-axis transfer assembly 3 and the Z-axis transfer assembly 4 are working, the drive motor 61 is started, and the drive motor 61 drives the screw guide rail 62 to rotate, and the slider 63 on the screw guide rail 62 moves linearly according to the rotation of the screw, thereby realizing the precise displacement of the moving end 6 of the X-axis transfer assembly 3 and the moving end 6 of the Z-axis transfer assembly 4. At the same time, as the slider 63 moves, the slider 63 drives the connecting plate 73 and the slide plate 72 to slide smoothly along the slide rail 71, so that the clamping mechanism 5 can perform precise transplanting in the corresponding direction, thereby realizing the precise movement of the engine connecting rod workpiece in the horizontal and vertical directions, improving the accuracy and stability of the transplantation, and ensuring that the workpiece can accurately reach the specified position.
[0032] See also Figure 1 as well as Figure 2The mobile end 6 of the X-axis transplanting assembly 3 and the mobile end 6 of the Z-axis transplanting assembly 4 also include a reducer 64, one end of the reducer 64 is connected to the drive motor 61, and the other end of the reducer 64 is connected to the screw guide rail 62.

The power adjusted by the reducer 64 is then transmitted to the screw guide rail 62, thereby driving the slider 63, the connecting plate 73 connected thereto, and the slide plate 72 to move accurately. The setting of the reducer 64 improves the stability of the transplanting process, reduces impact and vibration, makes the transplanting action more accurate and reliable, and prolongs the service life of the equipment.
[0033] See also Figure 1 as well as Figure 2 The moving end 6 of the X-axis transfer assembly 3 and the moving end 6 of the Z-axis transfer assembly 4 are both provided with a plurality of sensors 65, and the sensors 65 are used to detect the position and speed of the slider 63 for accurate positioning.

[0034] See also Figure 1 as well as Figure 3 The cylinder 51 is fixed on the slide plate 72, and the cylinder 51 is a double-piston rod cylinder. The double piston rods of the cylinder 51 are horizontally arranged. The two clamping arms 52 are arranged on two different piston rods of the cylinder 51. The clamping arm 52 includes a first vertical plate 521 connected to the piston rod of the cylinder 51. The bottom wall of the first vertical plate 521 is provided with a horizontal plate 522. The horizontal plate 522 is located below the cylinder 51. The horizontal plate 522 has a second vertical plate 523 protruding in a direction away from the cylinder 51 on one side of the horizontal plate 522 away from the first vertical plate 521. The cylinder 51 drives the two second vertical plates 523 to approach each other to clamp the engine connecting rod workpiece.
[0035] Specifically, the first vertical plate 521 is detachably connected to the piston rod of the cylinder 51, and a mounting plate 524 is integrally formed on the side of the horizontal plate 522 close to the first vertical plate 521 in the direction of the first vertical plate 521, and the mounting plate 524 is detachably connected to the first vertical plate 521, and the two second vertical plates 523 are parallel to each other. In the process of clamping the engine connecting rod workpiece, the double piston rods of the double piston rod cylinder shrink horizontally, and the piston rod drives the first vertical plate 521 to move horizontally, and the horizontal plate 522 at the bottom of the first vertical plate 521 moves accordingly, and the second vertical plate 523 located on one side of the horizontal plate 522 is also close to the engine connecting rod workpiece in the horizontal direction, and the two second vertical plates 523 cooperate with each other to realize the clamping action of the engine connecting rod workpiece. Through the mutual cooperation of the cylinder 51, the first vertical plate 521, the horizontal plate 522 and the second vertical plate 523, the clamping action is more stable and accurate, and the engine connecting rod workpieces of different sizes can be reliably grasped, which improves the accuracy and stability of the clamping.
[0036] The bottom of the horizontal plate 522 is fixedly connected with a stabilizing plate 54, which is fixedly connected to the side wall of the second vertical plate 523, and is used to provide support for the second vertical plate 523. When the second vertical plate 523 is subjected to the reaction force from the engine connecting rod workpiece, the stabilizing plate 54 can enhance the structural strength of the second vertical plate 523 and reduce the possibility of deformation. The provision of the stabilizing plate 54 enhances the structural stability of the clamping arm 52 and prevents deformation or damage due to force during the clamping process.
[0037] The two second vertical plates 523 are detachably mounted with a clamping plate 53 on one side close to each other. The clamping plate 53 is arranged to protect the clamping arm 52 during the clamping operation and reduce the wear of the clamping arm 52. The detachable feature of the clamping plate 53 facilitates replacement when it is severely worn, reduces maintenance costs, shortens equipment downtime and maintenance time, and keeps the production line running continuously and efficiently.
[0038] The implementation principle of this embodiment is:
[0039] When it is necessary to clamp the engine connecting rod workpiece, first, the cylinder 51 starts working, the piston rod of the cylinder 51 extends, driving the two symmetrically arranged clamping arms 52 to move away from each other, and the first vertical plate 521 and the horizontal plate 522 move with the piston rod, and the horizontal plate 522 drives the second vertical plate 523 to move accordingly, so that the two symmetrically arranged second vertical plates 523 move away from each other; then the engine connecting rod transplanting robot unit starts the X-axis transplanting component 3 and the Z-axis transplanting component 4 to move according to the position information of the engine connecting rod workpiece. The moving end 6 of the X-direction transfer assembly 3 drives the screw guide rail 62 to rotate through the driving motor 61, so that the slider 63 slidably connected thereto moves in the X direction, that is, moves in the horizontal direction. The slider 63 drives the connecting plate 73 to move, thereby driving the slide plate 72 and the Z-direction transfer assembly 4 installed on the slide plate 72 to move horizontally as a whole to a precise position; then the moving end 6 of the Z-direction transfer assembly 4 also drives the motor 61, the screw guide rail 62 and the slider 63 to cooperate, so that the transfer end 7 of the Z-direction transfer assembly 4 moves in the vertical direction, and then accurately adjusts the position of the clamping mechanism 5 to align it with the engine connecting rod workpiece; finally, the cylinder 51 continues to work, and the piston rod of the cylinder 51 contracts, driving the two symmetrically arranged clamping arms 52 to approach each other, and the first vertical plate 521 and the horizontal plate 522 move with the piston rod, and the horizontal plate 522 drives the second vertical plate 523 to move accordingly, thereby clamping the engine connecting rod workpiece.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
