Description

Technical Field

[0001] This utility model relates to the field of robot gripper technology, specifically to a robot gripper used for gripping and polishing automotive clamp castings. Background Technology

[0002] Grippers are the most common type of end effector. They can be mounted on industrial robot arms to directly grasp workpieces or perform operations, and have the functions of clamping, transporting, and placing workpieces to a certain position.

[0003] During the grinding process of automotive body castings, a gripper device is used to pick up and move the castings to a grinding machine for grinding. Traditional gripper devices require manual operation to move the gripper to the casting and manually calibrate it to complete the gripping action, which is cumbersome and relatively inefficient. Therefore, we propose a robotic gripper for gripping and grinding automotive body castings. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a robotic gripper for gripping and grinding automotive clamp castings.

[0005] The technical solution adopted by this utility model to solve its technical problem is a robot gripper for gripping and grinding automotive clamp castings. It includes a mounting frame, with cylinders mounted at both ends of the mounting frame. A transmission rod is mounted through the power output end of the cylinders and passes through the mounting frame. First hinges are provided on both sides of the bottom end of the transmission rod, and the gripper is rotatably connected to the transmission rod through the first hinges. A second hinge is mounted on the top end of the gripper adjacent to one side of the transmission rod, and the gripper is rotatably connected to the bottom end of an auxiliary rod through the second hinge. The auxiliary rod is fixedly connected to the bottom end of the mounting frame.

[0006] By adopting the above technical solution, during the process of moving the installation frame, the grooves that match the positioning clamp casting surface are first calibrated according to the first and second positioning components. Then, the first and second positioning components can be inserted into the corresponding grooves to complete the positioning calibration operation when gripping. Subsequently, the cylinders at both ends of the installation frame are operated to push the transmission rods downward, thereby causing the grippers to deflect toward one side of the auxiliary rod under the restriction of the first hinge and the second hinge at the bottom of the auxiliary rod. The grippers on both sides deflect inward at the same time to clamp the clamp casting and achieve the purpose of gripping and holding. Then, it is transported to the grinding equipment for grinding operations.

[0007] Specifically, the bottom two ends of the mounting frame are fitted with first positioning components on one side of the transmission rod, and the bottom two ends of the mounting frame away from the first positioning components are respectively fitted with second positioning components.

[0008] By adopting the above technical solution, when installed at the robot end effector, the positioning clamp casting is calibrated by the cooperation of the first positioning component and the second positioning component.

[0009] Specifically, the two jaws engage and hold the clamp body casting.

[0010] By adopting the above technical solution, the grippers set on both sides of the mounting frame rotate in opposite directions to clamp the two sides of the clamp body casting, thereby achieving the purpose of gripping and holding.

[0011] Specifically, the internal frame of the mounting frame is equipped with an electrical junction box.

[0012] By adopting the above technical solution, the operation of various electric devices installed at the mounting frame is controlled through the wiring connection of the electrical junction box.

[0013] Specifically, the top of the mounting frame is detachably fitted with a mounting base for connecting a robot end effector.

[0014] By adopting the above technical solution, the device is connected to the robot's end effector via a mounting base, and then connected to the robot's internal control program via an interface to perform operations.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the process of moving the installation frame, the technical solution of this application first uses the first and second positioning components to coordinate with the sensor to calibrate the grooves opened on the surface of the positioning clamp casting. Then, the first and second positioning components can be inserted into the corresponding grooves to complete the positioning calibration operation when gripping. Subsequently, the cylinders at both ends of the installation frame are operated to push the transmission rods downward, thereby causing the grippers to deflect toward one side of the auxiliary rod under the restriction of the first hinge and the second hinge at the bottom of the auxiliary rod. The grippers on both sides deflect inward at the same time to clamp the clamp casting to achieve the purpose of gripping and holding, and then transport it to the grinding equipment for grinding operation.
