Abstract: An auxiliary device for a mechanical arm includes a supporting base, two reciprocating engines, a rotational plate, and four suction members. The reciprocating engine includes a cylinder and a driving rod. The cylinder is configured for driving the driving rod linearly and reciprocating along its longitudinal axis. The cylinder is rotatably fixed to the supporting base, thereby defining a first rotational axis therebetween. The driving rod is rotatably fixed to the rotational plate, thereby defining a second rotational axis therebetween. The rotational plate is also directly and rotatably fixed to the supporting base to be rotatable about a third rotational axis defined therebetween. The three rotational axes are parallel. The four suction members are fixed to the rotational plate.

Abstract: An exemplary pin bending device (200) includes a base (210), a sliding member (230), a fixing member (240), and a latch member (250). The sliding member (230) is slidably positioned on the base and defines a plurality of holes (2303) for receiving first portions of pins. The fixing member is fixed on the base. The latch member is movably positioned on the base. The latch member is able to move towards the fixing member in a direction perpendicular to the sliding direction of the sliding member and engage with the fixing member to fix second portions of the pins.

Abstract: A transportation apparatus includes a base, a pair of guideways fixed on the base in parallel, a rodless cylinder installed on one of the pair of guideways and including a sliding block operable to be driven by the rodless cylinder to slide along one of the pair of guideways, a supporting member fixed on the sliding block, a lift cylinder installed on the supporting member, and a manipulating member installed on the cylinder. Each of two opposite sides of the supporting member is configured with an upper roller and a side roller abutting against an upper side and an inner side of one of the pair of the guideways, respectively. The manipulating member is operable to be driven by the cylinder to move along a direction different from an extending direction of the pair of guideways.

Abstract: A pipe fixture includes a main body including a receiving hole and a first through hole communicating with the receiving hole, a first positioning pin received in a first end portion of the first through hole including a screw hole and a first pressing portion, and a knob including a screw rod suitable to engage with the screw hole of the first positioning pin, a knob top and a step portion. When the knob extends through the second end portion of the first through hole and is screwed into the screw hole, the first positioning pin moves and presses the pipe so as to fix the pipe, and when the knob is unscrewed from the screw hole, the first positioning pin moves away from the pipe so that the pipe is released.

Abstract: A clamp changing apparatus includes a coupling device capable of being secured on a robot arm and a clamp-holding device. The coupling device includes a main body defining a blind hole, a connecting portion defining a through hole communicating with the blind hole, and a piston. The connecting portion has a ring-shaped protrusion aligned with the through hole facing away from the main body. The protrusion defines a plurality of holes running through the lateral wall thereof, each of the holes receives a rigid ball in which the diameter is bigger than the depth of the hole. The piston is received in the blind hole and the through hole, and is slidable along them to push the rigid balls out of the protrusion. The clamp-holding device is capable of being fixed to a clamp and defines a latching hole corresponding to the protrusion.
