Quick testing tool for machining dimension of complicated casting and testing method thereof

Abstract

The invention discloses a quick testing tool for a machining dimension of a complicated casting and a testing method thereof. The quick testing tool comprises a testing platform, a reference positioning assembly, a lateral positioning assembly, a pin assembly and a testing measuring tool. A lower end surface testing boss is arranged on the testing platform and furthermore the contour of the lower end surface testing boss matches the contour of a lower end-surface bevel of a standard-dimension casting, wherein a clearance exists between the contour of the lower end surface testing boss and the contour of the lower end-surface bevel of the standard-dimension casting. An upper end surface detecting template is fixed by means of the pin assembly. Furthermore the contour of the upper end surface detecting template matches the contour of the upper end-surface groove of the standard-dimension casting. Testing to the edge bevels of the upper end surface and the lower end surface of the casting can be finished by means of a sliding condition of the testing measuring tool in the clearance. The edge contour of a lateral testing template matches the contour of edge bevels at two sides of the standard-dimension casting, and furthermore the edge contour of the lateral testing template abuts against the contour of the edge bevels at two sides of the standard-dimension casting. Testing to the edge bevels at two sides of the casting can be finished by means of a sliding condition of a bevel contour template at the edge bevels at two sides of the casting. The quick testing tool and the testing method have advantages of simple structure, convenient operation, high use effect, high use value and high popularization value.

Description

technical field [0001] The invention relates to a detection tool for machining dimensions of complex castings and a detection method thereof, in particular to a detection tool and a detection method suitable for checking casting welding groove contours and space dimensions, and belongs to the field of workpiece detection. Background technique [0002] In the field of vehicle parts processing, various complex machined castings, such as bogie brackets, are key components in the vehicle connection frame. Generally speaking, during the processing of this type of casting, after the casting is cast, it is necessary to open multiple welding grooves in different directions and spatial positions on the outer circumferential side wall of the casting. The purpose of setting the welding groove is to facilitate and simplify the casting assembly process in the subsequent casting welding process. [0003] After the casting is finished, double-layer welding grooves will be provided on the ...

Problems solved by technology

[0006] Although the above patent can achieve the purpose of product size detection, the technical solution structure in the above patent is relatively simple, and can only detect a single plane of the product.

Moreover, this technical solution can only detect casting products with regular shapes. For products with irregular shapes such as complex machined castings, the above technical solution cannot complete the corresponding detection.
