Description

Technical Field

[0001] The utility model relates to the technical field of jigs for detecting the perpendicularity of springs, and specifically relates to a jig for detecting the perpendicularity of springs. Background Technique

[0002] The jig for detecting the perpendicularity of a spring is to check whether the spring forms a 90-degree angle with the base surface to determine whether the perpendicularity of the spring meets the standard.

[0003] For example, a rapid detection tool for the perpendicularity of a spiral spring with the authorization announcement number of "CN109931854A". After the spiral spring is placed on the fitting plane, its end face will quickly fit with the fitting plane due to the magnetic attraction, and then it is manually pushed to the non-magnetic reference column to observe the perpendicularity. This not only eliminates the waiting time for free standing and stability, improves the detection efficiency, but also avoids the deviation caused by manual observation of the end face fitting, achieving the effect of fast and good perpendicularity detection. However, when detecting the spring, it can only fix the magnetic spring. Now most springs are made of spring steel, including ordinary alloy spring steel, special alloy spring steel, carbon spring steel, etc. Many materials do not have magnetism, so the spring cannot be fixed, resulting in the jig for detecting the perpendicularity of the spring being unable to detect various springs, making it have limitations in use.

The inner wall of the bracket is processed with a groove, the inner wall of the groove is connected with a detection structure, the top of the bracket is fixedly connected with a second vertical rod, the left side of the bracket is connected with a placement structure, and the front and rear ends of the bottom of the right side of the bracket are respectively fixedly connected with a bottom plate. The inner walls of the two bottom plates are respectively threadedly connected with bolts.

[0007] Preferably, the detection structure includes a straight plate and a screw rod. The upper and lower sides of the straight plate are respectively in contact with the upper and lower sides of the inner wall of the groove. The right side of the straight plate is rotatably connected to the left side of the outer wall of the screw rod. The right side of the screw rod is fixedly connected with a handle. The top of the handle is fixedly connected with a first vertical rod. A sleeve is inserted on the outer wall of the first vertical rod.

[0008] Preferably, the outer wall of the screw rod is threadedly connected to the right side of the bracket.

[0009] Preferably, the outer wall of the first vertical rod is slidably connected to the top notch of the bracket.

The left side of the top of the cross plate is fixedly connected to the bottom of the first curved plate. The right side of the top of the cross plate is fixedly connected to a second curved plate.
