Description

Bent pipe gauge for automobile

Technical Field

The utility model relates to the technical field of automobile inspection tools, in particular to an automobile bent pipe inspection tool.

Background

Among the various components of the automobile, the use rate of the automobile pipe is high, and the automobile pipe is applied to a plurality of component parts of the whole automobile. In the process of producing the car pipe, the size and the bending radian of a plurality of car pipes can be involved. In the existing production, the pipe diameter of the car pipe is measured by adopting a manual scale, and meanwhile, the radian of the car pipe is measured manually. Such a detection method is time-consuming and cannot improve the detection accuracy. The existing automobile bent pipe detection tool can only detect bent pipes with one bending, and when the radian of bent parts of different bent pipes is measured, different radian detection tools are required to be replaced, so that the workload of workers is greatly increased.

In order to solve the above problems, a bent pipe inspection device is disclosed in chinese patent publication No. CN210862494U, which includes a base plate, a fixing seat, a locking seat, a reference seat and a detecting device, wherein the fixing seats are installed on the left and right sides of the base plate, rollers are installed on the fixing seats through rotating shafts, a positioning table is arranged on the fixing seats, a locking seat is installed on the base plate at the outer side of the fixing seat, locking screws are arranged on the locking seat in a threaded connection manner, and a measuring scale is installed on one end of the fixing seat; an electric push rod is arranged below the fixed seat on the base plate, and a datum seat is fixedly connected with the driving end of the electric push rod. According to the utility model, the bent pipe can be driven to move forwards through the roller on the fixing seat, before detection, the bent pipe is fixed on the positioning table through the locking screw, so that the plane of the bent pipe is fixed, and then the detection tool plate on the detection device is tightly attached to the straight line section after the bent pipe is bent, so that two bending angles of the space continuous bent pipe can be simply, accurately and efficiently detected at one time. However, the inspection tool can only detect bent pipes with the same thickness and the same distance between two bending positions, and has low processing efficiency and poor practicality, and does not meet the production requirements of modern enterprises, so the inspection tool for the bent pipes for the automobiles is provided to solve the problems.
