Eccentric balance weight structure of stone sawing machine transmission mechanism

Abstract

An eccentric balance weight structure of a stone sawing machine transmission mechanism comprises a top frame arranged between a front vertical column and a rear vertical column. A saw frame is positioned below the top frame and provided with a plurality of saw blades, a transmission mechanism capable of driving the saw frame to vertically move back and forth is arranged at the top of the top frame and comprises a motor and a spindle, the motor and the spindle are arranged at the top of the top frame and are in transmission connection, and the spindle is connected with the saw frame through an eccentric block. The eccentric block is in a disk shape, a spindle hole is arranged at the center of the eccentric block and connected with the spindle, an eccentric shaft adjacent to the spindle hole is arranged on the eccentric block, and a semicircle of the eccentric block with the eccentric shaft is lighter than the other semicircle of the eccentric block. The semicircle of the eccentric block with the eccentric shaft is provided with a plurality of balance weight holes, and the other semicircle of the eccentric block is solid. Stress is balanced when the spindle rotates, sway of the eccentric block is avoided, the saw frame stably and vertically moves back and forth, and the stone sawing effect of a stone sawing machine is ensured.

Description

technical field [0001] The invention relates to a stone sawing machine, in particular to an eccentric counterweight structure of a stone sawing machine transmission mechanism. Background technique [0002] On September 7, 2011, I disclosed a main shaft structure of a large-scale stone sawing machine in Chinese Patent Document No. CN102172987A. The large-scale stone sawing machine includes a saw frame that slides up and down between the front column and the rear column, and the saw frame There are a number of saw blades / bars on the top; the main transmission mechanism includes a main shaft connected to the saw frame, and the main shaft is connected to the driving motor; the main shaft is connected to the saw frame through an eccentric block and a connecting rod. The left and right sides of the saw frame are respectively connected to the driving motor through the main shaft; the speed of the two main shafts is the same. The main shaft is driven by the eccentric block and conn...

AI Technical Summary

Problems solved by technology

However, due to the use of belt transmission in the transmission mechanism, its volume is relatively large, which is not convenient for daily maintenance and maintenance. At the same time, the stone saw machine occupies a large area. After long-term use, the wear of the left and right belts is inconsistent, which affects the consistency of its speed.
