Description

Technical Field

[0001] The invention relates to the field of inspection tools, in particular to a turbine shell rocker arm welding angle inspection tool which converts height into angle. Background Art

[0002] When using existing detection methods to detect the welding angle of the turbine housing rocker arm, there are several conventional angle measurement methods: (1) Universal angle ruler measurement method: does not meet the conditions for using an angle ruler and is not applicable.

[0003] (2) Simple projection measurement method: Not applicable when the measured element is blocked and cannot be projected.

[0004] (3) Three-coordinate measurement method: Applicable, but it is difficult to use three-coordinate to perform online detection and judgment of product quality, and it does not meet the requirements of fast and convenient measurement for batch production inspection at the production site.

[0005] It can be seen that the above methods and the instruments used have certain defects. In order to improve the processing quality and efficiency, it is necessary to invent a new instrument for detecting the welding angle of the turbine casing rocker arm. Summary of the invention

The slide is arranged on the upper part of the inner side of the seat plate. The inner end surface of the slide is provided with an inclined groove body. The cover plate is arranged on both sides of the inner end surface of the slide. The cover plate serves to limit the sliding block slidably connected in the groove body. The sliding block is connected to the longitudinal support plate.

[0012] As a further preferred embodiment of the present invention, the longitudinal support plate includes a metal connecting portion and a wear-resistant portion which are sequentially arranged from the outside to the inside, and a push handle is provided at one end of the longitudinal support plate.
