A Device for Quickly Determining Angular Holes

Abstract

The invention discloses a device for rapidly determining an angular hole, and the device comprises a support plate (2) and a positioning pin (3), wherein the support plate (2) is a flat plate with parallel upper and lower surfaces, three through holes vertical to the upper surface of the support plate (2) are formed in the support plate (2), and the hole center distance and the hole center connecting line included angle of the three through holes on the support plate (1) are consistent with the hole center distance and the hole center connecting line included angle of the angular hole to be determined on a spray pipe; a handle (1) is vertically connected to the upper surface of the support plate (2); and the positioning pin (3) is detachably arranged in the through hole, and the outer diameter of the positioning pin (3) is smaller than the aperture of the angular hole to be determined on the spray pipe. The device for rapidly determining the angular hole can quickly find the actual positions of the two angular holes, thereby saving the processing time; and furthermore, the angular hole can be prevented from being determined incorrectly, a part is prevented from being scrapped during machining, and the machining cost is saved.

Description

technical field [0001] The invention belongs to the technical field of machining, in particular to a device capable of rapidly determining an angular positioning hole during machining. Background technique [0002] The nozzle is an important part of the aero-engine, such as figure 1 and figure 2 As shown, there are two special angular holes on the mounting edge of the straight section of the outer wall of the part, a test seat is welded on the cylinder, and mounting holes are opened on the front and rear mounting edges, and the mounting holes are consistent with the straight section of the outer wall. The special angular holes are related. Every time you find the position of two special holes on site, you must use a vernier caliper to measure one hole by one hole. The number of measurements is too many, time-consuming and labor-intensive, and it is easy to make mistakes. If you make a mistake, the angular position If it is wrong, it will cause the parts to be processed an...

The special angular holes are related. Every time you find the position of two special holes on site, you must use a vernier caliper to measure one hole by one hole. The number of measurements is too many, time-consuming and labor-intensive, and it is easy to make mistakes. If you make a mistake, the angular position It will determine the error, resulting in parts processing and scrapping, resulting in major economic losses
