Description

Technical Field

[0001] The utility model relates to the technical field of detection tools, in particular to a detection tool for sheet metal bending parts. Background Art

[0002] After the sheet metal parts are bent, the bending angle needs to be tested to ensure that the sheet metal parts can reach the standard bending angle.

[0003] For example, patent number CN217700789U is a detection tool for sheet metal bending parts, including a base, both sides of the bottom of the base are fixedly connected with symmetrically arranged support feet, the side wall of the base is provided with an adjustment groove, an adjustment block is slidably arranged in the adjustment groove, a fixed shaft is fixedly connected to the side wall of the adjustment block, and a fixed block is fixedly connected to the end of the fixed shaft away from the adjustment block. The above document still has shortcomings. When in use, through the setting of the rotating arm, the push rod, the ruler plate and the stop block, when the ruler plate drives the stop block to contact the side wall of the sheet metal part, the bending angle of the sheet metal part can be obtained by using the pointer block to point to the value on the ruler plate, so that the sheet metal part can be understood. Whether the bending angle can meet the standard, the bending angle of the sheet metal part can be accurately detected, and under the action of the torsion spring, it can be automatically reset, and it is also convenient to use. However, when the detection tool in the above document positions the sheet metal bending part, the sheet metal bending part is positioned by the elasticity of the spring. The spring is an elastic part. When the ruler contacts the edge position of the sheet metal bending part, the sheet metal bending part is prone to tilt. When the sheet metal bending part is detected, the positioning effect of the sheet metal bending part is poor. At the same time, the detection device in the above document can only detect a single position of the sheet metal bending part, which is not convenient for detecting multiple positions of the sheet metal bending part.
