Embodiment Construction

[0014] Go to attached image, figure 1 An electric gripper is shown and indicated with reference number 10 . The gripper comprises a housing 12 having an electrical connection plug 14 protruding from the housing. A power source (not shown) is connected to connector 14 . A pair of gripper fingers 16, 18 extend from the housing.

[0015] figure 2 An exploded view of the gripper device 10 is shown. Housing 12 has a generally rectangular box shape, including at one end a pair of walls 20, 22 that receive a clamp, as will be described hereinafter. The walls define a channel 24 including a base wall 26 . A hole 27 is formed in said base wall 26 enabling access into said housing 12 . The housing 12 includes an additional top wall 28 that includes an aperture 29 to enable passage of a motor assembly into the housing 12 . In addition, a cover 30 is secured in bore 29 by a C-ring 32 to retain the motor assembly in said housing 12 .

[0016] The gripper 10 includes a motor assemb...

Abstract

Provided is an electric gripper which has a housing with a motor. A gearhead is coupled with the motor. A controller is electrically coupled with the motor to control the gripper via the motor. A compliance device is coupled with the motor. The compliance device absorbs impact energy created by the device. A drive mechanism is coupled with the compliance device and with a jaw movable on the housing. Fingers are coupled with the jaw that opens and closes to grip a part.

Description

technical field [0001] The present disclosure relates to an electric gripper including a driver having a torsional compliance device having impact energy absorbing properties. Background technique [0002] Most electric grippers in use today are servo driven, providing them with the performance of a geared drive motor. The deceleration occurs in a manner that limits wear on the drive parts. This reduces the possibility of jamming the gripper members. These drives are constructed with expensive motors and feedback devices, such as encoders and controllers, which are complex and require extensive programming. To reduce the cost of electric grippers, it is desirable to use DC brushed motors. [0003] The DC motor will be hardwired to the gripper and run to a hard stop, ie fully open / closed to grip the part. Here, the motor must stop abruptly when these hard stops are encountered. From an energy standpoint, a system entering a hard stop position has both the drive electrica...
