Problems solved by technology

The equipment of the three-coordinate inspection machine is expensive, and the inspection time is long. In the actual production process, the utilization rate of the three-coordinate inspection machine is high, and the waiting time for inspection is relatively long. Therefore, in order to ensure that the product position is 100% qualified during the mass processing of products, generally Special position gauge for control
However, the surface profile can only be detected by three-coordinate inspection machine due to the limitation of processing procedures.

Embodiment 1

[0015] A combination type and insertion type flange position degree and surface contour degree detection device, which includes a detection body 1, a shape plate 2, a latch 3, a positioning pin 4 and a positioning shaft 5. The shape plate 2 and the inspection body 1 cooperate through the inner and outer spigot structures. The shape plate 2 and the inspection body 1 form an inner cavity space for placing the flange. The positioning pin 4 restricts the degree of freedom of the shape plate. The bolt 3 installation holes provided on the inspection body 1 are fixed on the inspection body 1 to form a measuring gauge for detecting the flange position. The positioning shaft 5 is fixed on the inspection body 1 through the positioning shaft 5 mounting holes provided on the inspection body 1. The shaft 5 forms the flange positioning datum, and the shape plate 2 forms a contour gauge for detecting the flange surface.

[0016] The bolt 3 cooperates with the mounting hole of the bolt 3 on t...

Abstract

The invention discloses a testing device for position accuracy and surface profile of a flange. The testing device comprises a testing fixture, a profile plate, latches and a positioning shaft. The profile plate is connected with the testing fixture through an inner spigot structure and an outer spigot structure. The profile plate and the testing fixture form an inner chamber space for placing the flange. The inner profile surface of the profile plate forms a flange surface profile testing gauge. The latches are fixed on the testing fixture through latch mounting holes which are arranged on the testing fixture. The latches form a flange position accuracy testing gauge. The positioning shaft is fixed on the testing fixture through a positioning shaft mounting hole which is arranged on the testing fixture. The positioning shaft forms a flange positioning reference. The testing device has a combined structure and can perform functions of testing position accuracy and testing surface profile, thereby shortening secondary testing time. The testing device has advantages of high identification capability, high convenience in operation, simple and reliable structure, and effective cost reduction function. Furthermore production speed of products is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing of auto parts, and relates to a detection auxiliary device for parts, in particular to a combination type and insertion type flange position degree and surface contour degree detection auxiliary device. Background technique [0002] At present, in the mechanical processing of auto parts, the position inspection and surface contour of the parts are usually detected by the three-coordinate inspection machine. The equipment of the three-coordinate inspection machine is expensive, and the inspection time is long. In the actual production process, the utilization rate of the three-coordinate inspection machine is high, and the waiting time for inspection is relatively long. Therefore, in order to ensure that the product position is 100% qualified during the mass processing of products, generally The special position gauge is used for control. However, the surface profile can only be dete...
