Spindle rotation rate controller

Abstract

The invention discloses a main shaft rotation rate controller, which includes an automatic milling machine, the automatic milling machine includes an installation box and an object placement assembly, an XY direction axis assembly is arranged between two groups of the installation boxes, and an XY direction axis assembly is arranged below the XY direction axis assembly There is a bracket, and the bottom end of the inner cavity of the installation box is installed with a deceleration assembly. The main shaft rotation rate regulator controls the operation of the electric telescopic rod to drive the telescopic column to elongate, and the U-shaped slider connected to the top of the telescopic column will move upward at the notch of the chute, and the U-shaped slider connected to the The telescopic rod on the outer wall will swing down to the left and pull the prismatic block upwards, thereby realizing the expansion and contraction of the three groups of prismatic blocks. When the prismatic block is expanding, the arc connected to the outer wall of the prismatic block The curved tooth block will be stretched in conjunction with the upper hinge plate, so that the diameter of the arc tooth block becomes larger, thereby reducing the rotational speed of the rotating shaft.

Description

Technical field [0001] The present invention relates to a field of automation, specifically a spindle rotation rate regulator. Background [0002] Machine tool spindle refers to the machine tool to drive the workpiece or tool rotation of the shaft, in the machine is mainly used to support transmission parts such as gears, pulleys, transmission of motion and torque, the performance of the machine tool spindle accelerator mainly depends on the desired speed and power transmission ratio optimization design, mechanical spindle accelerator must be designed for long-term production work, therefore, the transmission kinetic energy must be minimal to ensure the best performance, CNC machine tool spindle speed regulation is automatically performed in accordance with the control instructions, In order to meet the requirements of the main drive speed regulation and output torque at the same time, CNC machine tools often use electromechanical combination methods, that is, the simultaneous us...

Problems solved by technology

[0003] However, there are some deficiencies in the traditional spindle rotation rate controllers currently on the market. The speed regulation does not use mechanical speed regulation, that is, the parallel and serial speed regulation of the circuit, and this kind of speed regulation is easy to appear in long-term use. Damage, because all the effect depends on the quality of the motor, the failure of the motor will directly lead to the suspension of automation, and at the same time, it requires skilled personnel to adjust the speed and repair the line
