Problems solved by technology

[0003] The purpose of the present invention is a torque-enhancing device for milling machines with variable frequency feed and variable speed, which solves the problem that in the low-frequency and low-speed area, that is, the rotational speed does not reach the constant power range, the torque cannot reach the rated value during the variable-frequency feed process of the existing lifting table milling machine. Smaller, unable to withstand the load requirements during feed cutting, which makes the cutting weak and does not meet the performance requirements of the milling machine for heavy cutting

Abstract

The invention discloses a frequency conversion feeding variable speed enhancing torque device for a milling machine. The device comprises a speed changing frame, a first positioning shaft capable of rotating in the axial direction and a second positioning shaft capable of rotating in the axial direction and moving in the radial direction are arranged on the speed changing frame, a first dual synchronous toothed-shaped belt pulley coaxial with the first positioning shaft is arranged on the first positioning shaft, and a second dual synchronous toothed-shaped belt pulley coaxial with the secondpositioning shaft is arranged on the second positioning shaft. By means of the device, the problems that during the frequency conversion feeding process of an existing lifting platform milling machineand in a low frequency and low speed section which is the section in which the rotation rate does not reach a constant power, the torque cannot reach a rated value resulting in smaller torque, so that loading demands of feeding cutting cannot be borne, cutting is weak, and the performance demands of heavy cutting of the milling machine cannot be met are effectively solved.

Description

technical field [0001] The invention relates to a torque-enhancing device for milling machines with variable-frequency feed and variable speed. Background technique [0002] At present, the traditional frequency conversion feed and speed change process of the traditional milling machine brings convenience in operation, and the speed change structure is relatively simple. Combined with the characteristics of the frequency converter, often in the low frequency and low speed area (the speed does not reach the constant power range), the torque cannot reach the rated value. value, the torque is small, and it cannot bear the load requirements during feed cutting, which makes the cutting weak and does not meet the performance requirements of the milling machine for heavy cutting. Contents of the invention [0003] The purpose of the present invention is a torque-enhancing device for milling machines with variable frequency feed and variable speed, which solves the problem that in...
