Car door frame clamp for intelligent grinding and polishing by robot

Abstract

The invention provides a car door frame clamp for the intelligent grinding and polishing by a robot, which comprises a trolley component (101) and a clamp component (102); the trolley component (101)comprises a base plate (4); the clamp component (102) comprises a clamp frame and clamping structures; the clamp frame is fixedly connected or detachably connected with the base plate (4), and one ormore clamping structures are arranged on the clamp frame; the clamping structure comprises clamping jaws, a clamping cylinder and a cylinder bracket, wherein the clamping jaws and the clamping cylinder are all arranged on the cylinder bracket; the clamping jaws comprise a moving clamping jaw and/or a fixed clamping jaw, and the moving clamping jaw is connected with the clamping cylinder. The device has the advantage of high precision on positioning a work piece and is suitable for working conditions of grinding, polishing, and the like, which require high positioning precision; the feeding ofthe irregular parts, such as the vehicle door frame, can be achieved, and the labor cost and the time cost are saved.

Description

technical field [0001] The invention relates to the field of grinding and polishing equipment, in particular to a door frame fixture for robot intelligent grinding and polishing. Background technique [0002] At present, in the automatic assembly line of robots such as auto parts, the weld seam grinding after arc welding of the door frame is mainly done by manual grinding and polishing, which has low efficiency, unstable surface quality, and great harm to the human body. The modified grinding station is automatically polished by a robot. However, due to the high positioning accuracy requirements for the workpiece during the grinding process, the fixture used for welding is generally used in the station, and the error is relatively large, which cannot reach the thickness of the weld seam after grinding. within 0.5mm requirement. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide a door frame clamp fo...
