Abstract

The invention discloses a floating reaming jig with a nylon shaft used for positioning. The floating reaming jig comprises a base (1), a side positioning plate (2), the nylon shaft (3) and a nut (4). A to-be-processed part is a workpiece (5), a to be-reamed hole (6) is arranged, reaming processing is performed with an original hole serving as the standard, the positioning is performed through other additional processing surfaces having been processed, and the standard conversion causes an error. According to the technical scheme, a method for eliminating the contradiction is that two floating factors which are limited elasticity of the nylon shaft and a certain gap of the side positioning plate are utilized to form floating adapting to the part precision requirements, the goal of high reaming coaxiality precision is achieved, and the floating reaming jig is high in practicality.

Description

technical field [0001] It belongs to the field of mechanical processing. Background technique [0002] The existing reaming method adopts pure floating positioning without any positioning support. When the reamer just enters the hole to be processed, sometimes the positioning of the workpiece differs too much, resulting in breaking the reamer and damaging the workpiece. , the entrance of the reaming hole in this case is threaded, which is easy to damage the threaded surface; there is another processing method that is not floating, using a rigid shaft and a side positioning plate to position the plate, which is complete positioning. The benchmark is an indirect benchmark, and sometimes the coaxiality between the reamed hole and the existing hole does not meet the required accuracy; resulting in a low product qualification rate. Contents of the invention [0003] <1> Technical problems to be solved [0004] The problem to be solved by the present invention is the pro...
