Three-pin frame journal functional area detection device and method

Abstract

The invention discloses a three-pin frame journal functional area detection device and method. The device mainly comprises a functional surface area comparison panel and the like, wherein two side fixing plates are installed at two sides of a top positioning plate, the functional surface area comparison panel is installed among the two side fixing plates and the top positioning plate, every two ofthe top positioning plate, the two side fixing plates and the functional surface area comparison panel are connected to form a cube to be sleeved on a three-shaft neck for detection, and the functional surface area comparison panel is provided with a window hole. According to the invention, the detection device of the function detection area with the window hole is adopted to replace manual nakedeye visual detection and vernier caliper universal measuring tool detection, so that suspicious products can be rapidly detected, whether the journal working function face grinding area meets the requirement can be effectively recognized, products with defects are selected, and misjudgment caused by a measurement position and a visual standard error is effectively avoided.

Description

technical field [0001] The invention relates to the field of tripod frames, in particular to a detection device and method for journal function areas of tripod frames. Background technique [0002] The three-pin bracket is the main part of the three-ball constant velocity universal joint on the car. In order to reduce weight and improve the performance of the part, the journal part is optimally designed into a flat head shape. This design structure needs to ensure that the working functional surface area of ​​the three-pin frame triaxial journal is all finished, with a small range of stable size and surface roughness; for the working functional area, the naked eye visual inspection of employees is usually used at present. Sorting means, if there is a collapsed state on the edge of the working function area of ​​the three-pin frame journal, it will be sorted out. In addition, the universal measuring tool of the vernier caliper is used to measure the working function area of ​...

This design structure needs to ensure that the working functional surface area of ​​the tripod tri-journal is all finished, with a small range of stable size and surface roughness; for the working functional area, the naked eye visual inspection of employees is usually used at present. Sorting means, if there is a collapsed state on the edge of the working function area of ​​the three-pin frame journal, it will be sorted out. In addition, the universal measuring tool of the vernier caliper is used to measure the working function area of ​​the three-pin frame journal of the suspicious product to judge whether the product is qualified. Improper measurement will lead to misjudgment, resulting in the circulation of defective products, which will eventually lead to early failure of product functions

The existing detection methods have large errors, the standard is difficult to unify, and the work efficiency is relatively low, and it is easy to cause misjudgment
