Fine adjustment mechanism

Abstract

The invention discloses a fine adjustment mechanism. The fine adjustment mechanism is used for micro-adjustment of a box in box of a hot working mechanical device and comprises an outer box and an inner box arranged inside the outer box. One end of the inner box is hinged to the outer box through a rotating shaft. The bottom of the end, far away from the rotating shaft, of the outer box is provided with a drive structure driving the inner box to move around the rotating shaft. The drive structure comprises an internal thread sleeve which is arranged on the bottom wall of the outer box in a penetrating manner, an outer nut screwed into the internal thread sleeve and used for supporting the inner box, a spline housing connected to the bottom end of the outer nut, a speed reducer fixed to thelower side of the bottom of the outer box through a support and a motor which is in drive connection with the speed reducer. The end of an output shaft end of the speed reducer is provided with a key, and the output shaft is in drive connection with the spline housing. Through mechanical type adjustment structure design, the fine adjustment mechanism can be connected with a remote controller to be operated and controlled, and micro-angle adjustment of the inner box can be conveniently conducted so that machining demand can be met; workers do not need be close to the hot working mechanical device to conduct adjustment, so that potential safety hazards are avoided, the safety performance is provided, and the fine adjustment mechanism is quite practical.

Description

technical field [0001] The invention relates to a micro-adjustment mechanism of a box in a thermal processing mechanical equipment, in particular to a fine-adjustment mechanism. Background technique [0002] On special metal thermal processing equipment, the outlet of the liquid metal in the inner tank sometimes needs to be fine-tuned to meet the requirements of the production product during the operation of the equipment. The equipment in the prior art requires workers to approach the equipment to adjust. Since the temperature is very high during the adding process, it is very dangerous to use manual approach adjustment, which is likely to cause work accidents, and the adjustment of existing equipment is also very troublesome. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a fine-tuning mechanism that can conveniently adjust the inner box of the thermal processing equipment, so as to realize the horizontal angle req...
