Flexible three-finger clamp

Abstract

The invention provides a flexible three-finger clamp. The flexible three-finger clamp comprises a shell, a rotating motor arranged in the shell, an inner rotating column, a connecting disc and flexible clamping jaws, the inner rotating column is connected with the rotating motor through the connecting disc, three inclined-strip-shaped grooves are formed in the rotating column, vertical-strip-shaped grooves used for being matched with the inclined-strip-shaped grooves are formed in the shell, the first connecting ends of the flexible clamping jaws are sequentially connected with sliding blocks,the vertical-strip-shaped grooves and the inclined-strip-shaped grooves through connecting bolts, and the second connecting ends of the flexible clamping jaws are fixed to the shell. The flexible three-finger clamp is simple in structure, convenient to operate, stable in clamping and uniform in force bearing, and the three clamping jaws are all made of flexible materials to avoid damage to objects in the clamping process; and the motor drives a rotating disc to rotate, thus the clamping jaws are controlled to move up and down, the objects are clamped by extruding the clamping jaws, and when the clamping force is greater than tolerance of products, the clamping jaws are subjected to slight plastic deformation due to the flexible materials of the clamping jaws to absorb the excess clampingforce.

Description

technical field [0001] The invention relates to the technical field of clamps, in particular to a flexible three-finger clamp. Background technique [0002] Industrial fixtures generally use jaw cylinders or three-jaw cylinders. When clamping fragile and fragile products such as eggs and glasses, the method of installing sponges on the jaws is used to ensure that the products are not clamped during the clamping process. will be destroyed. [0003] However, some products are not only fragile but also have different sizes. Therefore, in addition to installing the sponge on the jaws, the strength of the jaws must also be controlled at all times. As for the problem of different product sizes, the existing technology solves the problem by replacing the cylinder claws of the corresponding size, which is not only more slippery and troublesome, but also checks the strength and speed of the cylinder claws when they are engaged, which leads to clamping problems. The cost increases a...

[0003] But some products are not only fragile but also have different sizes. Therefore, in addition to installing the sponge on the jaws, it is also necessary to control the strength of the jaws at all times.

As for the problem of different sizes of products, the existing technology solves the problem by replacing the cylinder claws of the corresponding size, which is not only more slippery and troublesome, but also checks the strength and speed of the cylinder claws when they are engaged, which leads to clamping The cost increases and the process of increasing the strength and speed of the calibration
