Abstract

The invention discloses a support plate nut rivet hole drill die, belongs to the field of auxiliary jigs for machine manufacturing, and aims at solving the problems that during positioning of an existing support plate nut rivet hole drill die, deviation is likely to happen, and consequently the drilled support plate nut rivet hole edge distance cannot meet the requirement. Through the additional arrangement of a hole edge distance positioning pin, the hole edge distance positioning pin is utilized for directly positioning the hole edge distance of corresponding rivet die holes, and accordinglyit is ensured that the drilled rivet hole edge distance meets the corresponding requirement. Meanwhile, due to the arrangement of the hole edge distance positioning pin, in the drill die positioningprocess, the drill die can be directly positioned through a center hole positioning pin and the hole edge distance positioning pin, accordingly, deviation of the drill die due to manual fixing positioning can be avoided, and the rivet hole forming precision is improved.

Description

technical field [0001] The invention relates to the field of auxiliary jigs for mechanical manufacturing, in particular to a drilling template for rivet holes of pallet nuts. Background technique [0002] When using pallet nut rivet hole drilling jigs to drill rivet holes in some areas with narrow operating space, due to the narrow space, the positioning of pallet nut rivet hole drilling molds is unstable, resulting in positioning deviation, which often leads to the drilling of pallet nuts. The hole margin of the rivet hole is insufficient and does not meet the requirements; for example, the margin of the metal hole is usually required to be 2 times the diameter of the rivet hole, and the margin of the composite material hole is required to be 2.5 times the diameter of the rivet hole. The reason is that we found that the existing pallet nut rivet hole drilling templates are completely positioned by the workers when positioning the drilling holes manually. Therefore, it is in...
