AI Technical Summary

Technical Problem

The pressure bar of the existing melting machine bracket cannot be effectively limited in a horizontal state, and the fixed pressure bar is easily damaged by corrosive gases, which leads to the crucible falling and making replacement difficult.

Method used

A sample melting machine bracket with dual-limit detachable pressure rods is designed. It adopts a herringbone pressure rod limiting groove structure, including a pressure rod guide groove, a normal limiting groove, and a tilting limiting groove. The pressure rod is automatically positioned and limited by gravity. Mounting holes are provided on the side plate of the bracket to facilitate the installation and removal of the pressure rods.

Benefits of technology

It improves the stability of the pressure bar and the accuracy of sample melting operations, simplifies the pressure bar replacement process, reduces maintenance costs, and extends the service life of the equipment.

Abstract

The utility model relates to a sample melting machine technical field, concretely relates to a kind of sample melting machine bracket of double limiting detachable pressure rod, including bracket side plate, crucible bearing frame, bottom support rod and pressure rod, herringbone recess is set on bracket side plate, and it is constituted by pressure rod guide groove, normal limit slot and dump limit slot, and the three are communicated.Pressure rod is slided into normal limit slot by guide groove and realizes horizontal limit, and pressure rod is slided to dump limit slot when bracket is dumped and prevents the falling of crucible.Both ends of pressure rod are smaller than central section in diameter, facilitate installation and removal and reduce friction, and the first mounting hole and the second mounting hole of bracket side plate are respectively connected with crucible bearing frame and bottom support rod, to enhance structural stability.The design solves the problem that existing fixed pressure rod is difficult to replace due to corrosion damage, and the insufficient limiting leads to shaking, improves the stability and safety of closed sample melting condition through double limiting mechanism, simplifies maintenance process, prolongs service life and reduces maintenance cost.
