[0002] At present, in order to reduce costs, major automobile factories produce multiple types of engines on the same production line, resulting in a wide variety of injector bushings with similar inner hole sizes. The error rate of manual assembly of injector bushings will increase. It is necessary to solve the problem of reducing the error rate of mixed-line production and improving automation efficiency on the premise of cost savings.

When using a robot to grasp the injector bushing and using a rotating cylinder or the sixth axis of the robot arm to rotate for degreasing and gluing, the rotation angle and speed are limited, and the degreasing and gluing are not very uniform. Moreover, the pipeline package of the robotic arm affects the rotation of the arm. At the same time, the robot directly grasps the already processed degreased and glued injector bushing for assembly, which requires too much preparatory work and will also increase the number of auxiliary devices for degreasing and gluing and the labor cost, which is uneconomical. Content of the Utility Model

On the basis of the device for clamping the injector bushing, it can achieve controllable uniform rotation and rotation cycle control of the injector bushing, so that the plasma degreasing head and the gluing head of the gluing device can be fixed, and the manipulator rotates itself to complete degreasing and gluing, reducing the manufacturing cost of other auxiliary devices. The production cost of this device is relatively economical.
[0005] To achieve the above purpose, the present utility model provides the following technical solution: A rotary inner hole expansion claw grasping manipulator device includes a bottom plate.

One side of the screw is threadedly mounted with one end of the motor mounting plate. On one side of the surface of the screw, a nut is threadedly connected.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. By setting the pushing assembly to cooperate with the transmission and rotation assembly to hold the workpiece, and then through the induction control assembly to sense the workpiece, and then through the cooperation of the transmission and rotation assembly to rotate and degrease and apply glue to the workpiece, the present utility model solves the problems that manual cleaning of anti-rust oil, then applying glue, and then assembling the injector bushing cannot achieve automation, with low work efficiency. When using a robot to grasp the injector bushing and using a rotating cylinder or the sixth axis of the robot arm to rotate for degreasing and applying glue, the rotation angle and speed are limited, the degreasing and glue application are not very uniform, and the pipeline package of the robotic arm affects the rotation of the arm. At the same time, when the robot directly grasps the already processed injector bushing that has been degreased and glued for assembly, too much preparatory work is required, which will also increase the number of auxiliary devices for degreasing and applying glue and the labor cost, and it is uneconomical.

The movement of the cylinder joint can push the core rod out of the positioning rod, and at this time, the expansion claw can retract due to gravity. After the manipulator moves to the grasping position, the cylinder pulls the core rod back through the cylinder joint. At this time, the expansion claw is extruded by the core rod and holds the workpiece tightly, facilitating subsequent processing. Description of the Drawings

During use, the screw 12 can be threadedly fixed inside the limiting plate 11, facilitating the fixing of the motor mounting plate 21 by the limiting plate 11 through the screw 12 and enhancing the fixing convenience during use.
[0035] The working principle and usage process of the present utility model: During use, an external manipulator can be installed and fixed to the positioning sleeve 6. Before grasping the workpiece, the locking cylinder 33 pushes out the core rod 35 through the cylinder joint 34. At this time, the expansion claws 29 can retract due to gravity. When the manipulator moves to the grasping position, the locking cylinder 33 pulls back the core rod 35 through the cylinder joint 34. At this time, the expansion claws 29 are pushed out by the core rod 35 to hold the workpiece tightly. At this time, each expansion claw 29 can extend simultaneously due to the action of the slope on the core rod 35, ensuring the coaxiality of the workpiece and the positioning rod 28. At this time, the magnetic switch on the locking cylinder 33 detects that the cylinder 33 is clamped in place, and the laser sensor 44 detects the presence or absence of the workpiece. When the manipulator is in the degreasing and gluing state and the workpiece needs to rotate, the motor 23 can be started. The output end of the motor 23 rotates and drives the driving pulley 24 to rotate through the reduction of the reducer 22. The rotation of the driving pulley 24 can drive the belt 25 to rotate. The rotation of the belt 25 can drive the driven pulley 26 to rotate. The rotation of the driven pulley 26 can drive the positioning rod 28 to rotate, thereby rotating the workpiece. After completing the rotation action, the manipulator places the workpiece into the assembly hole. The locking cylinder 33 pushes out the core rod 35 through the cylinder joint 34. At this time, the expansion claws 29 can retract due to gravity, and the workpiece detaches from the manipulator. The manipulator withdraws, achieving the compatibility with workpieces such as injector bushings with slightly different inner hole diameters and cylindrical workpieces with inner holes that require degreasing, gluing, and assembly on the outer wall. Optimizing the form of the equipment auxiliary device, with reliable structure, cost reduction, simultaneous realization of automation, improved efficiency, and avoidance of resource waste.
[0036] In summary, for the rotary inner hole expanding jaw grasping manipulator device, the pushing component 2 is set to cooperate with the transmission rotating component 3 to hold the workpiece, and then the induction control component 4 is used to sense the workpiece, and then the transmission rotating component 3 is used to rotate and degrease and apply glue to the workpiece, solving the problems that manual cleaning of antirust oil, then applying glue, and then assembling the injector bushing cannot achieve automation, with low work efficiency. When using a robot to grasp the injector bushing and using a rotating cylinder or the sixth axis of the robot arm to rotate for degreasing and applying glue, the rotation angle and speed are limited, the degreasing and glue application are not very uniform, and the pipeline package of the robotic arm affects the rotation of the arm. At the same time, the robot directly grasps the degreased and glue-applied injector bushing that has been processed for assembly, which requires too much preparatory work and will also increase the number of auxiliary devices for degreasing and glue application and the labor cost, which is uneconomical.
