Variable-pitch clamping jaw mechanism

Abstract

The invention discloses a variable-pitch clamping jaw mechanism. The variable-pitch clamping jaw mechanism comprises a clamping jaw opening and closing mechanism and a clamping jaw variable-pitch mechanism, wherein the clamping jaw opening and closing mechanism comprises a base plate, an opening and closing cylinder, a driving plate, a left spacing bottom plate, a right spacing bottom plate, a first wire rail, second wire rails, a left cam roller, a right cam roller, a left connecting block and a right connecting block; and the clamping jaw variable-pitch mechanism comprises second connectingblocks, clamping jaw connecting blocks, guide rods, a spacing limiting rod, a driving sliding chute block, a sliding pin and a spacing cylinder, and a left and right symmetric sliding chute is formedin the driving sliding chute block. The variable-pitch clamping jaw mechanism controls opening and closing of each pair of clamping jaw connecting blocks, namely opening and closing of the clamping jaws, through the clamping jaw opening and closing mechanism; meanwhile, the distance between the clamping jaw connecting blocks is controlled through the clamping jaw variable-pitch mechanism, namely the distance between each pair of clamping jaws is adjusted, so that materials can be grabbed when material spacing needs to be changed in different places in the carrying process of products; and meanwhile, clamping jaw elastic mechanisms are arranged to ensure that each product is grabbed and has the advantages of being simple in structure, convenient to operate, high in automation degree, wide in application range and the like.

Description

technical field [0001] The invention belongs to the technical field of automatic processing, and in particular relates to a variable distance gripper mechanism. Background technique [0002] With the development of science and technology, industrial manipulators are more and more widely used in automated production. How to design an end effector with high efficiency and low cost to realize the pick-and-place of materials is of great significance to actual production. In actual production, sometimes it is necessary to complete the grasping action of the material and change the spacing of the product during the product handling process. For example, the vibrating plate feeding is often used in automation equipment. are closely arranged, and in order to realize the positioning of the material in the process carrier, the gap is usually distributed, so it is necessary to change the object distance of the jaws, that is, it is necessary to apply a distance-changing mechanism.

Problems solved by technology

[0003] The end effector of the common variable distance mechanism is generally a vacuum suction cup or a gripper cylinder. However, due to the large volume of the gripper cylinder and the inconvenient arrangement of the air pipe, the limitations of the vacuum suction cup make it unsuitable for tight arrangement and suitable for gripping Variable distance grabbing of products
