In the description of the utility model, it should be explained that the positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is only based on the positional relationship of the orientation shown in the drawings, which is only for the convenience of describing the utility model, and does not indicate or imply that the referred parts have a specific orientation, are constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0027] Specific implementation method 1: Combination Figures 1 to 3 This embodiment is described. This embodiment includes a rotary driver 701, a connection seat 702, a cylinder 706, a clamp connection plate 707, a first clamp 709 and a second clamp 708. The rotary driver 701 is mounted on an external connection plate 600. The connection seat 702 is bolted onto the rotary driver 701. The cylinder 706 is mounted on the inner side of the connection seat 702. Two parallel clamp connection plates 707 are mounted on the left and right ends of the cylinder 706. The first clamp 709 is fixedly mounted on the upper ends of the two clamp connection plates 707. The second clamp 708 is fixedly mounted on the lower ends of the two clamp connection plates 707. The utility model adopts a connection seat that is bolted onto the rotary driver. The cylinder is mounted on the inner side of the connection seat. Two parallel clamp connection plates are mounted on the left and right ends of the cylinder. The first clamp is fixedly mounted on the upper ends of the two clamp connection plates. The second clamp is fixedly mounted on the lower ends of the two clamp connection plates. It is possible to grab and transport two types of equipment, 120 / 120-1 brake valve, without changing the equipment.

[0028] Specific implementation method 2: Combination Figures 1 to 3This embodiment is described. The difference between this embodiment and the first embodiment is that the utility model further includes two first cylinder connection plates 703, two second cylinder connection plates 705, a first slide rail 704 and a first slider. One of the first cylinder connection plates 703 is installed on the inner side of the connection seat 702. The inner surface of one of the first cylinder connection plates 703 is installed with a horizontally arranged first slide rail 704. The two first cylinder connection plates 703 are connected with the two second cylinder connection plates 705 to form a rectangular frame. The length of the second cylinder connection plate 705 is smaller than the length of the first cylinder connection plate 703. The two ends of the cylinder 706 slide through the two second cylinder connection plates 705 and are fixedly connected with the two clamp connection plates 707. The rectangular frame facilitates the fixing of the cylinder 706 and does not participate in the telescopic action of the cylinder 706. The clamp connection plate 707 is provided with a first slider that slides in cooperation with the first slide rail 704. The slide rail 704 plays a guiding role to prevent the second clamp 708 of the 120-type brake valve and the first clamp 709 of the 120-1 type from deviating. The design dimensions of the first cylinder connecting plate 703, the two second cylinder connecting plates 705, and the first slide rail 704 vary with the size of the brake valve, and cooperate with the rotary driver 701 to realize the 360° rotation of the parts. Such a setting not only realizes the clamping action of the brake valve parts, but also does not need to repeatedly replace the clamps when multiple parts are cross-operated. Other components and connection methods are the same as those of the specific implementation method 1.

[0029] Specific implementation method three: Combination Figures 1 to 3 The present embodiment is described. The present embodiment is different from the first embodiment in that a limit stopper is provided on the connection seat 702, and the limit stopper is used to limit the rotation angle of the rotary driver 701. The other components and connection methods are the same as those of the first or second embodiment.

[0030] Specific implementation method four: Combination Figures 1 to 3 This embodiment is described. The difference between this embodiment and the first embodiment is that the cylinder 706 is a double-acting cylinder. The double-acting cylinder is equipped with a solenoid valve, an air inlet pipe and an air outlet pipe. The other components and connection methods are the same as any one of the first to third embodiments.

[0031] Specific implementation method five: Combination Figures 3 to 7To illustrate this embodiment, based on specific embodiment one, this embodiment includes a base frame 100, an X-axis horizontal lateral movement mechanism 200, a Y-axis horizontal lateral movement mechanism 300, a fixed plate 400, a Z-axis vertical movement mechanism 500, a connecting plate 600 and a rotating clamping mechanism body 700. The X-axis horizontal lateral movement mechanism 200 is slidably installed on the top of the base frame 100 along the X-axis horizontal direction of the base frame 100, the Y-axis horizontal lateral movement mechanism 300 is slidably installed on the top of the X-axis horizontal lateral movement mechanism 200 along the Y-axis horizontal direction of the base frame 100, the fixed plate 400 is fixed on the top of the Y-axis horizontal lateral movement mechanism 300, the plate surface direction of the fixed plate 400 is perpendicular to the X-axis horizontal direction of the base frame 100, the upper end of the Z-axis vertical movement mechanism 500 is installed on one side of the fixed plate 400, the lower end of the Z-axis vertical movement mechanism 500 is installed with a connecting plate 600, and the rotating clamping mechanism body 700 is installed on the connecting plate 600. This embodiment can change the structural length of the basic frame to adapt to the corresponding working conditions. The basic frame can be made of a lighter aluminum alloy material to make the device more anti-corrosive. The functions of identifying parts and measuring the distance to parts can be realized by installing an ultrasonic device or a laser distance measuring device on the rotating clamping mechanism. The multifunctional motion structure that can be installed on different truss equipment can complete horizontal / vertical lateral movement along the X-axis, Y-axis, and Z-axis in a certain space, and can rotate freely along the X-axis. Through multiple power output units, each axis can be moved separately, and multi-axis associated movement can also be achieved to complete the positioning and grasping of parts. Automatic grasping and transfer devices are used instead of manual handling to reduce the labor intensity of employees and reduce the safety hazards of the automatic valve movement process. Solutions are formulated based on the three core aspects of intelligent operation, energy saving and efficiency, and safety management. The position of the brake valve is judged by the pre-installed sensor on the conveyor line, and the system controls the robot to reach the edited clamping position, and the end fixture judges and grasps the 120 / 120-1 brake valve. The equipment grabs the brake valve to the corresponding interface of the detection platform according to the pre-planned path for air tightness detection. After the inspection, the qualified brake valves are placed on the conveyor line tooling board, and the unqualified products are placed in the repair area. By adjusting the structural dimensions of the equipment base frame, the constraints of the complex on-site environment can be met, and the functions of parts grabbing and transportation can be completed. The rotary drive can drive the clamping mechanism components to rotate 360°, and realize the cross-operation of multiple parts without changing the fixture, which can effectively improve work efficiency. The base, fixed plate, and connecting plate are combined together, and all movements such as lateral movement and rotation can be controlled separately and coordinated. Better structural integration is achieved, the overall weight of the mechanism is reduced, and the stability and reliability of the mechanism are improved.
