Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings.

[0039] The cam-type lifting and rotating mechanism of the coal quality analyzer is mainly composed of a cam-type lifting part and a rotating part.

[0040] Such as figure 1 , 2 , 3, the cam-type lifting part is mainly composed of a lifting seat 16, a reduction motor 15, a cam 22, a cam bumper 24, and a linear slide rail 20. The reduction motor 15 is fixed on the lifting seat 16, and the cam 22 is installed on the reduction motor 15. On the camshaft, there is a square power transmission block 23 that transmits the motion and torque of the motor between the cam and the camshaft. Its function is equivalent to a key. The linear slide rail 20 is located above the cam 22. The sliding parts are fixed together and supported on the cam 22. The outer ring surface of the cam 22 and the cam bumper 24 is covered with a bearing 21. The upper and lower pos...

Abstract

The invention discloses a cam type rising-falling and rotating mechanism of coal analysis instrument, which comprises a cam type rising-falling part and a rotating part. The cam type rising-falling part mainly consists of a rising-falling seat, a reducer motor, a cam, a cam collide block and a linear guide rail; the rotating part mainly consists of a stepping motor, a mounting block, an index plate, a rotating plate supporting rod, and a rotating plate; and the rotating part is assembled together with the slipping part of the linear guide rail by the mounting block, and is supported and guided to slip by the linear guide rail. The mechanism has the beneficial effects of ingenious design, low processing and assembling difficulty, low manufacturing cost, low power demand, extremely easy control, simplicity and reliability as well as improved automation degree and stability.

Description

technical field [0001] The invention relates to the field of coal quality analysis instruments, in particular to a cam-type lifting and rotating mechanism that can automatically move a certain crucible to a certain position in a three-dimensional space, thereby realizing automatic weighing of the crucible. Background technique [0002] In the series of coal quality analysis instruments, in order to realize automatic testing of industrial analysis indicators, it is necessary to accurately move the crucible to the weighing rod through the lifting and rotating mechanism and move the crucible from the weighing rod to the crucible hole of the turntable, so a set of Reliable, stable and high-performance lifting and rotating mechanism. [0003] At present, the lifting and rotating mechanisms of various coal quality manufacturers generally have the following problems: [0004] 1) The structure is relatively complex, the manufacturing cost is high, and the assembly is difficult; ...
