Problems solved by technology

[0002] The existing gear reduction structure is generally made of metal materials. However, due to the high cost and heavy weight of metal materials, in order to reduce costs, the transmission gear of the manipulator is made of plastic. However, due to the use of plastic injection molding or printing molding, The tooth parts of the printed plastic parts are very easy to wear, and the entire manipulator needs to be scrapped after wear, which makes the service life of the manipulator short, and the replacement of the manipulator is time-consuming and laborious, hindering the normal production of the entire production line

Abstract

The invention provides a manipulator structure with a demountable rack. The rack is demountably mounted on a gear body of a manipulator and can be directly replaced once being worn, and accordingly normal production of a production line is guaranteed, and the service life of the manipulator is guaranteed. The manipulator structure comprises a manipulator body with a gear structure, the gear structure comprises a gear body and a rack structure, the gear body and the manipulator body form an integral structure, the rack structure is an arc carrier with outward-convex tooth structures uniformly distributed on the outer periphery, the tooth structures are uniformly distributed along the outer peripheral arc direction of the arc carrier, inward-convex embedded projections are uniformly distributed on the inner periphery of the arc carrier along the inner peripheral arc direction of the arc carrier, and an interval space is reserved between every two adjacent embedded projections.

Description

technical field [0001] The invention relates to the technical field of deceleration transmission structures, in particular to a detachable rack manipulator structure. Background technique [0002] The existing gear reduction structure is generally made of metal materials. However, due to the high cost and heavy weight of metal materials, in order to reduce costs, the transmission gear of the manipulator is made of plastic. However, due to the use of plastic injection molding or printing molding, The teeth of the printed plastic parts are very easy to wear, and the entire manipulator needs to be scrapped after wear, which makes the service life of the manipulator short, and the replacement of the manipulator is time-consuming and laborious, hindering the normal production of the entire production line. Contents of the invention [0003] In view of the above problems, the present invention provides a manipulator structure with a detachable rack, which allows the rack to be d...
