Problems solved by technology

[0002] The existing grabbing devices often set corresponding grabbing devices according to the uniqueness of the workpiece. Therefore, when there are many types of workpieces, different grabbing devices will be selected, which will affect the research and development costs and manufacturing costs of the grabbing devices. All will result in a considerable improvement; on the other hand, when a new workpiece needs to be grasped, it is necessary to redesign a grasping device
In short, the current grasping device has poor adaptability
[0003] However, the current two-jaw adaptive grasping device can grasp the workpiece with a small weight and lack of enveloping degree.

Abstract

The invention is applicable to the technical field of grabbing devices, and provides a three-jaw adaptive grabbing device. The device is provided with a first clamping jaw, a second clamping jaw and a third clamping jaw, end parts of the first clamping jaw, the second clamping jaw and the third clamping jaw are provided with same clamping plates, the first clamping jaw and the second clamping jaw have the same structures and respectively comprise a connecting rod part and a cable transmission part, the connecting rod part comprises a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a fifth connecting rod and a first clamping jaw hinged in sequence, a clamping plate of the second clamping jaw is fixedly connected to an end part of the fifth connecting rod, the cable transmission part comprises a first support mounted on the first connecting rod, a second support mounted on the third connecting rod and a third support mounted on the fourth connecting rod, a first roller, a second roller and a third roller are arranged on the first support, the second support and the third support in sequence, the cable transmission part further comprises a transmission cable which bypasses the first roller, the second roller and the third roller in sequence and is fixed to the fifth connecting rod, the third clamping jaw comprises a telescopic push rod, and a clamping plate of the third clamping jaw is fixedly connected to an end of the push rod. The grabbing device can adapt to grabbing of workpieces with different shapes, can grab workpieces with high weight, and has good enveloping degree.

Description

technical field [0001] The invention relates to a grabbing device, in particular to a three-jaw self-adaptive grabbing device. Background technique [0002] The existing grabbing devices often set corresponding grabbing devices according to the uniqueness of the workpiece. Therefore, when there are many types of workpieces, different grabbing devices will be selected, which will affect the research and development costs and manufacturing costs of the grabbing devices. All will cause no small improvement; on the other hand, when new workpieces need to be grabbed, a kind of grabbing device needs to be redesigned. In a word, the adaptive ability of the current grabbing device is relatively poor. [0003] However, the current two-jaw adaptive grasping device can grasp a workpiece with a small weight and lack of enveloping degree. [0004] For this reason, the present invention proposes a three-jaw self-adaptive grabbing device, which can adapt to grabbing workpieces with diffe...
