Embodiment

[0023] The number of faces of the gear rod 2 in the end effector of the piston-type multi-claw robot is 4, such as Figure 5-8 As shown, the number of gears 9 and gear shafts 10 is four, and the number of groups of slide rails 12 is four groups. The input and output fluid through the two holes on the housing 3 drives the piston 1 to move, and the piston 1 drives it to be fixed. The connected four-sided gear rod 2 moves linearly; the four gears 9 are respectively installed on the four gear shafts 10, and the four gear shafts 10 are supported inside the housing 3 by a pair of bearings 11, and four groups of gear shafts are installed on the end surface of the housing 3 Slide rails 12, each set of slide rails 12 is equipped with a rack-type slider module, the rack-type slider module is composed of a rack-type slider 13 and a pair of cylindrical roller moving guide rails 14, each gear 9 All mesh with the gear bar 2 and its corresponding rack-type slider 13; the linear motion of the...

Abstract

The invention discloses a piston type multi-jaw robot end effector and relates to the technical field of robots. A piston and a toothed bar are fixedly connected through a bolt to form a driving mechanism. The driving mechanism is mounted in the shell. A first seal ring is mounted between the piston and the shell. A second seal ring is mounted between the toothed bar and the shell. A rear cover ismounted at the tail end of the shell. A third seal ring is mounted between the inner side of the rear cover and the shell. A clamp spring is mounted between the outer side of the rear cover and the shell. Gears are mounted on gear shafts. The two ends of each gear shaft are supported in the shell through two bearings correspondingly. Multiple sets of slide rails are mounted on the end face of theshell. A rack type sliding block module is mounted in each set of the slide rails. Each gear is engaged with the toothed bar and a corresponding rack type sliding block. By adopting the unique toothed bar, motion is transmitted to the rack type sliding blocks in multiple directions through the gears, the transmitted torque is large, and the synchronism is good. Moreover, the gear shafts are supported by cylindrical roller bearings, the motion damping of the gear shafts is small, and the motion efficiency is high.

Description

technical field [0001] The invention relates to a piston-type multi-claw robot end effector, which belongs to the technical field of robots. Background technique [0002] With the continuous development of the field of robot technology in our country, the reliability of industrial robots grabbing parts has been paid more and more attention by users. Most of the existing robot end effectors are clamp-type structures, most of which have low grasping strength, insufficient grasping accuracy and poor synchronization of grasping actions. [0003] In view of the above-mentioned defects, it is hoped to create a piston-type multi-claw robot end effector. The robot end effector has good long-term motion accuracy and high motion efficiency. The rack-type slider in two directions can transmit torque and has the advantages of high strength and high synchronization, which is in line with the future development trend of robot end effectors. Contents of the invention [0004] The objec...
