Embodiment 1

[0044] like Figure 1-Figure 8 As shown, a floating gripper is used for clamping an irregular workpiece 1 with a non-cylindrical outer surface for loading and unloading. The two moving parts 2a are arranged opposite to each other, and the two moving parts 2a can approach and move away under the drive of the driving part. The structure of the base 2 can refer to a parallel pneumatic gripper with patent application number CN201420154604.7. Gripper bases 3 are respectively connected to the two moving parts 2a, and clamping parts 4 are hinged to the outer parts of the two grip bases 3, and the two grip bases 3 can be opened and closed under the drive of the driving part. The base 2 is connected with a pusher 6 located between the two clamping members 4 , and an elastic member 7 with elasticity is arranged between the pusher 6 and the base 2 .

[0045] like Figure 1-Figure 3 As shown, the push piece 6 includes a central part 6b and four supporting parts 6c, the inner end of the...

Embodiment 2

[0051] The structure of the pushing member 6, the guiding structure, the structure of the elastic member 7 and the structure of the clamping member 4 are different from those of the first embodiment, and other structures are the same as those of the first embodiment. The push piece 6 is plate-shaped, and the push surface 6a is the end surface of the push piece 6 opposite to the base 2 . The guide structure includes a guide cylinder fixed on the outer edge of the push piece 6. There are several guide cylinders and they are evenly distributed. The guide shaft hole, the base 2 is provided with a fixed seat 9 corresponding to the guide cylinder, the fixed seat 9 is fixed with a guide shaft perpendicular to the push surface 6a, the guide shaft is inserted in the guide shaft hole and can be inserted along the guide shaft hole slide. Elastic part 7 can be spring leaf, and spring leaf is V-shaped, and one end is fixed on the push piece 6, and the other end is fixed on the base 2 or o...

Abstract

The invention provides a floating gripper and belongs to the technical field of machine tools. The problem that in the use process of an existing floating gripper, the positioning accuracy of an irregular workpiece is likely to be reduced is solved. The floating gripper comprises a base, and the base is connected with a plurality of gripper base bodies capable of being opened and closed; clampingparts are correspondingly hinged to the gripper base bodies, the base is connected with a pushing part located among the clamping parts, and an elastic part with elasticity is arranged between the pushing part and the base. According to the floating gripper, the positioning accuracy on the irregular workpiece in the use process can be improved.

Description

technical field [0001] The invention belongs to the technical field of machine tools and relates to a floating gripper. Background technique [0002] With the development of mechanization and automation, the application of robots in factories is becoming more and more extensive. The robot can realize the transportation of workpieces between machine tools, and can also perform loading and unloading operations on the machine tools, which greatly reduces labor costs and labor intensity. The gripper is set on the robot, and the workpiece is grasped by the gripper, and then the workpiece is transported. [0003] Common grippers include two-finger grippers and three-finger grippers, and the stability of two-finger grippers is worse than that of three-finger grippers. Grippers can be divided into parallel grippers and corner grippers according to different movement modes, among which parallel grippers are widely used in robots. The gripper includes a driving part and two clampin...
