Embodiment

[0031] like figure 2 As shown, the present invention defines three directions as the width direction X, the height direction Y and the thickness direction Z. The invention is a general gripper for car doors, which adopts a linear drive system to realize the movement of the gripping point, so that the gripper can adapt to the gripping section width difference ΔX, height difference ΔY and thickness difference ΔZ existing in doors of various models , that is, regardless of the arbitrary changes of the three grasping points A, B, and C in the X, Y, and Z directions, the universal gripper described in the present invention can be adjusted in three directions accordingly to realize a universal gripper corresponding to Grab different car doors.

[0032] The present invention consists of a mechanical arm body 100 , a first end effector unit 101 , a second end effector unit 102 , a third end effector unit 103 and a connecting flange 104 .

[0033] The connecting flange 104 is a mech...

Abstract

The invention discloses an universal gripper for a vehicle door. The universal gripper is characterized in that the universal gripper comprises a mechanical arm body, a first tail end execution unit,a second tail end execution unit and a third tail end execution unit are arranged on the mechanical arm body; the first tail end execution unit is fixedly connected with the mechanical arm body; the second tail end execution unit is connected with the mechanical arm body through a width and thickness double-freedom-degree moving device; and the third tail end execution unit is connected with the mechanical arm body through a width, thickness and height three-degree-of-freedom moving device. The universal gripper for the vehicle door has the advantages that the universal gripper is suitable forany three-hole positioning part, and is particularly suitable for vehicle body door parts, and the gripping point of the gripper adapts to the change of the position, the size and the plate thicknessof a positioning hole.

Description

technical field [0001] The present invention relates to a kind of fixture used in the process of door handling and welding in the welding workshop, especially relates to a kind of universal gripper for car doors which is used to adapt to the cross-sectional height difference and width difference existing in the doors of various different models, and belongs to Automotive machinery manufacturing technology field. Background technique [0002] In the process of body assembly, a series of fixtures are usually installed on the industrial robot through a fixed flange. Such fixtures are usually called robot grippers, which are used to transport various body parts from a station To another station or directly for welding, hemming and other processes. [0003] Ordinary door handles usually consist of a frame and three fixed-position detent cylinders, which are only suitable for one type of door. When a new model is added to the line, the original handle needs to be modified to make...
