Abstract
Featured is a gripper for a tailgate; such a gripper includes a rotation pad at each regulation surface of a locator and a clamper of each clamping unit, where a swivel ball is mounted on the rotation pad. Each clamping unit is movable in a vertical direction or a horizontal direction by a movement unit of a frame so as to be adaptable to angle differences of each regulation surface of the tailgate. Such a tailgate gripper further includes a frame having a tool mounting portion to mount a tool changer of a robot in a lower portion of a rear surface thereof.
Claims20
A gripper for a tailgate, comprising:
- a frame at which a tool mounting portion is disposed to mount a tool changer of a robot in a lower portion of a rear surface thereof;
- a vertical movement means that moves a sliding bracket along a guide rail in a vertical direction by an electric cylinder in an upper portion of the frame;
- a first clamping unit that is prepared to be moved in a vertical direction on an upper portion of the frame through the sliding bracket of the vertical movement means to make a first clamper regulate an upper middle of a tailgate by a first clamping cylinder through a first locator;
- horizontal movement means that respectively move the sliding bracket in a horizontal direction along the guide rail by the electric cylinder at both lower sides of the frame;
- and
- second and third clamping units that are prepared to be respectively moved in a horizontal direction at both lower sides of the frame through each sliding bracket of both horizontal movement means to make second and third clampers regulate lower sides of the tailgate by second and third clamping cylinders through second and third locators.

A gripper for a tailgate, comprising:
- a frame;
- a first clamping unit including a first clamper, the first clamping unit being configured so the first clamper regulates an upper portion of a tailgate;
- a vertical movement means operably coupled to the frame and the first clamping unit, the vertical movement means being configured to move the first clamping unit in a vertical direction so that the first clamper regulates the upper portion of a tailgate;
- second and third clamping units that are prepared to be respectively moved in a horizontal direction at both lower sides of the frame through a sliding bracket to make second and third clampers regulate lower sides of the tailgate by second and third clamping cylinders through second and third locators;
- and
- horizontal movement means operably coupled to the frame and respectively to the second and third clamping units;
- the horizontal movement means, being configured so as to cause the second and third clamping units to move in a horizontal direction so that the second an third clampers regulate lower sides of the tailgate,
- wherein the vertical movement means includes a sliding bracket, a guide rail and an electric cylinder, where the sliding bracket moves along the guide rail in the vertical direction by the electric cylinder disposed in an upper portion of the frame.
