Simple and rapid detection device special for deformation of large bearing seat cast steel blank

Abstract

The invention relates to the technical field of material detection, and discloses a large-scale bearing pedestal cast steel blank deformation special-purpose simple rapid detection device, which comprises a truss, the right end of the truss is movably connected with a clamping groove, the left end of the truss is fixedly and movably connected with an upright support, and the top end of the upright support is movably connected with a rotating ball. And the middle part of the rotating ball is movably connected with a detection line. According to the invention, the distances between the two clamping grooves and the center of the truss are adjusted, so that the distances between the two clamping grooves and the center of the truss are equal, the upright bracket is moved to be close to the arc surface of the bearing hole and fixed, several outermost angular points of the bearing seat are measured by the detection line connected by the rotating ball, and whether the bearing seat is deformed or not can be known by comparing the angular points with theoretical values. The detection speed is high, the operation is simple, the use condition is simple and convenient, the reaction speed in production can be accelerated, the waiting time in the production process is shortened, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of material detection, in particular to a special simple and rapid detection device for the deformation of a cast steel blank of a large bearing seat. Background technique [0002] The bearing seat casting of marine low-speed diesel engine is a kind of casting similar to sheet-like structure, which is prone to various deformations during the whole casting production process. The main deformation direction is that the four corners are lifted in the vertical direction of the flat plate. Before the blank is completed, it is necessary to confirm whether the casting is deformed, and whether the deformation exceeds the allowable range of casting error. Only after confirmation can it be sent for processing. Due to the large size of the castings, it is currently impossible for the foundry to perform rapid inspection before sending it to the processing workshop. Only after it is sent to the processing workshop for ma...

Problems solved by technology

[0004] The above-mentioned deformation detection method also has the following disadvantages: there is a certain error in the detected data, and it is necessary to establish a certain error range for each steel casting when using it. The data obtained by different people has deviations, and the data of this detector can only be for site reference
