The invention adopts the detection device with the function detection area with the window hole to replace manual naked eye visual detection and vernier caliper universal measuring tool detection, can quickly detect suspicious products, can effectively identify whether the grinding area of the working function surface of the journal meets the requirements or not, selects out insufficient products, and effectively avoids misjudgment caused by measurement position and visual standard errors.
Description
Technical Field
The invention relates to the field of tripod, in particular to a tripod journal functional area detection device and method.
Background
The tripod is a main part in a tripod constant velocity universal joint on an automobile, and a shaft neck part is optimally designed into a flat head shape in order to realize weight reduction and improve the performance of the part. The design structure needs to ensure that all the working functional surface areas of the three pin racks and the three journals are subjected to finish machining, and the three pin racks and the three journals have stable sizes and surface roughness in a small range; for the working function area, currently, a naked eye visual detection method is usually adopted for sorting, the edge of the working function area of the three-pin frame shaft neck is sorted when the edge has a corner collapse state, in addition, a vernier caliper general measuring tool is adopted for measuring the working function area of the three-pin frame shaft neck of a suspicious product to judge whether the product is qualified, and if the measurement is improper, misjudgment can occur, so that the defective product flows down, and finally the early failure of the product function can be caused. The existing detection means has large error, the standards are difficult to unify, the working efficiency is low, and the condition of misjudgment is easy to generate.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a device and a method for detecting a functional area of a three-pin-frame journal.
The purpose of the invention is achieved by the following technical scheme: the device and the method for detecting the functional area of the three-pin-frame journal mainly comprise a top positioning plate, two side fixing plates, a functional surface area comparison panel and a window hole, wherein the two side fixing plates are arranged on two sides of the top positioning plate, the functional surface area comparison panel is arranged between the two side fixing plates and the top positioning plate, the two side fixing plates and the functional surface area comparison panel are connected in pairs to form a cube which is sleeved on the three-pin-frame journal for detection, and the window hole is formed in the functional surface area comparison panel.
The size and the position of the window hole are set as the reference of the three-journal functional area to be detected.
The two side fixing plates are in clearance fit with two sides of the head of the three-axis neck of the three-pin frame.
The method for detecting the functional area of the three-pin-frame shaft neck mainly comprises the following steps:
1) sleeving a detection device on three journals of a tested three-pin frame part, wherein fixing plates on two sides are in clearance fit with two sides of the head of the three journals, and a top positioning plate is close to the end parts of the three journals;
2) the functional surface area of the window hole is opposite to the surface of the panel, which faces to the measured surface of the three shaft necks;
3) and after the position is adjusted, observing the surface quality condition of the part in the window hole area, and if the window hole area is the required finish machining surface, the product is qualified, otherwise, the product is unqualified.
The invention has the beneficial effects that: the invention designs and adopts the detection device with the function detection area with the window hole to replace manual naked eye visual detection and vernier caliper general measuring tool detection, can quickly detect suspicious products, can effectively identify whether the grinding area of the working function surface of the journal meets the requirements or not, selects out the products with deficiency, and effectively avoids misjudgment caused by measurement position and visual standard error; the problems that the manual naked eye visual detection standard is difficult to quantify, the vernier caliper is low in measurement efficiency, the positioning is inaccurate and misjudgment is easy are solved, and a quick, efficient and accurate means is provided for product quality detection.

The functional surface area contrast panel 3 is provided with a window 6. The size and the position of the window hole 6 are set as the reference of the function area of the three-axis neck 5 to be detected. A uniform quantifiable criterion can be determined.
The device and the method for detecting the functional area of the three-pin-frame shaft neck mainly comprise the following steps:
1) sleeving a detection device on a three-shaft neck 5 of a part to be detected of a three-pin frame 4, wherein fixing plates 2 on two sides are in clearance fit with two sides of the head of the three-shaft neck 5, and a top positioning plate 1 is close to the end part of the three-shaft neck 5, so that the detection position can be accurately positioned;
2) the functional surface area of the window hole 6 is opposite to the surface of the panel 3, which faces to the measured surface of the three shaft necks 5;
3) and after the position is adjusted, observing the surface quality condition of the part in the window hole 6 area, if the window hole 6 area is the required finish machining surface, the product is qualified, otherwise, the product is unqualified.
It should be understood that equivalent substitutions and changes to the technical solution and the inventive concept of the present invention should be made by those skilled in the art to the protection scope of the appended claims.
