Special detection device for detecting double-hole concentricity of sewing machine positioning block

Abstract

The invention relates to a special detection device for detecting the double-hole concentricity of a sewing machine positioning block. The special detection device comprises a base plate, a supporting base, a workpiece positioning rod and a workpiece detection concentric rod, and is characterized in that the bottom of the supporting base is hinged on the base plate through a rotating shaft, the upper end of the supporting base is provided with a groove used for placing a workpiece, the workpiece positioning rod is inserted at one side of the supporting base, the front end of the workpiece positioning rod extends into the groove, the workpiece detection concentric rod is inserted at the other side of the supporting base, and the workpiece detection concentric rod and the workpiece positioning rod are coaxially arranged. The special detection device for detecting the double-hole concentricity of the sewing machine positioning block is ingenious in design, simple in structure and convenient to use, and application of the device can simplify the detection process, accelerate the detection speed and improve the accuracy of a detection result.

Description

technical field [0001] The invention relates to a detection tool in the technical field of industrial sewing machine processing, in particular to a special detection device for double-hole concentricity detection of a positioning block of a sewing machine. Background technique [0002] There is a long through hole on the positioning block of the industrial sewing machine. Due to the long length of the hole, holes are punched from the left and right sides of the positioning block during processing, and finally connected to form a hole. The outer ends of the left and right sides of the long through hole have a section that needs to be connected with other components, so it is necessary to detect whether the two sections meet the concentricity requirement during processing. At present, when testing, a positioning rod is inserted on the left and right sides respectively, the probe of the detection instrument is placed on the positioning rod, the workpiece is rotated, and the ind...

Problems solved by technology

This method is cumbersome, and the human error in the measurement process is relatively large. For example, when the staff shakes their hands when using the instrument or does not notice the value changes, it will affect the final result and cause unqualified products to flow into the next process.

In addition, the existing detection method is more complicated and time-consuming to operate
