Description

Technical Field

[0001] This utility model relates to the field of tooling technology for components of a scraper conveyor, and more particularly to a cutting and positioning device for a hydraulic support sleeve. Background Technology

[0002] Scraper conveyors typically require hydraulic supports, and sleeves are commonly used components in hydraulic support structures, such as... Figure 1 As shown, the sleeve 1 has circular holes for mounting pins and oblong holes for connecting other components on its circumferential surface. The circular holes include two opposing first circular holes 101 and two opposing second circular holes 102. The oblong holes include a first oblong hole 103 and a second oblong hole 104. The line connecting the centers of the first oblong holes 103 and 104 is L1, and the axis of the opposing first circular holes 101 is L2.

Currently, the oblong holes of the sleeve 1 are typically machined using flame cutting, but achieving perpendicularity during cutting is difficult. Therefore, a machining fixture needs to be designed to save significant alignment time and improve cutting efficiency when machining the oblong holes of the hydraulic support sleeve.
