Space four-degree-of-freedom self-balancing revolving arm

Abstract

A space four-degree-of-freedom self-balancing revolving arm is mainly formed by a support portion, a main shaft portion, a big arm parallelogram mechanism, a cylinder, a small arm and an output portion. A location groove is arranged on the support portion, an axis of the location groove coincides with that of the support portion, the lower end of the main shaft portion is arranged in the location groove of the support portion through a bearing, the upper end of the main shaft portion is connected with the big arm parallelogram mechanism which is mainly composed of an upper transverse beam, a lower transverse beam and a lateral beam, one end of the cylinder is hinged onto the lateral wall of the main shaft portion, the other end of the cylinder is hinged onto the lower transverse beam, a small arm revolving joint is fixedly connected onto the lateral beam, one end of the small arm is connected with a joint shaft of the small arm revolving joint, and the output portion is fixedly connected with the other end of the small arm. The revolving arm is flexible in revolving, practical and convenient, has the advantages of high efficiency and low cost, and can narrow area of work sites while guaranteeing big working ranges.

Description

[0001] technical field [0002] The invention relates to a cantilever used in conjunction with a polysilicon crushing device, in particular to a space four-degree-of-freedom self-balancing rotary arm used for locating the grasping or crushing position of materials in polysilicon rod crushing. Background technique [0003] In the polysilicon preparation industry, the crushing of polysilicon rods mostly relies on manual hammering with steel hammers embedded in cemented carbide. Patent CN101376242 A discloses a hammer for crushing polysilicon, which can suppress the generation of silicon powder when crushing polysilicon. However, manual operation is still required, and the labor intensity is high and the production efficiency is low. In order to improve production efficiency and adapt to the automatic polysilicon production line, advanced mechanical equipment must be used. The application method of the patent CN201776156 U is to position the material first, then use the motor...

This device is complex to control and lacks flexibility

The impact crushing method is a promising application technology. The power source of the impact force can be not only potential energy, but also gas or liquid. However, in the impact crushing method, a rotating arm that matches the crushing device must be used. There is no such rotary arm in the world. Obviously, the existing technology and equipment cannot meet the application of the impact crushing method in the crushing of polysilicon rods.
