Description

Technical Field

[0001] The invention relates to the technical field of milling machine equipment, and in particular provides a cyclone milling machine transmission mechanism. Background Art

[0002] In the copper tube processing industry, the first processing step that the hollow tube billet cast from the melting furnace needs to go through is to remove the outer surface oxide layer, and this process is usually completed by a milling unit.

[0003] Attached Figure 1 The schematic cross-sectional view of a milling machine transmission mechanism commonly used for milling the oxide layer on the surface of a hollow tube is shown. The working principle of the milling machine transmission mechanism is as follows: first, the motor outputs power and drives the input shaft 110 to rotate, and then the power is transmitted through the transmission gear A111 to drive the rotating body 10 to rotate, and the power output by the rotating body 10 is transmitted in sequence through the fixed gear ring 122 and the transmission gear C123 to drive the output shaft 130 to rotate, and accordingly, the power output by the output shaft 130 is transmitted through the transmission gear B131 to drive the milling cutter 2 to rotate clockwise to perform milling on the surface of the copper casting.

[0004] Although the above device can meet the milling processing requirements of the oxide layer on the outer surface of the hollow tube blank, the above device still has the following difficult-to-overcome technical problems during production and application:

[0005] ①Although under normal circumstances, the milling effect of the milling cutter is better; however, when the surface of the billet is uneven and has oxide scale, the use of the down milling method will result in a rough surface of the billet;

[0006] ② Because there will be a certain gap between the rotating body and the gears during the assembly process, the use of down milling will cause vibration and increase the wear of the tool surface when the tool crawls on the surface of the ingot;

[0007] ③ Under the limitations of the existing structure, the ratio of the milling cutter speed to the rotating body speed cannot be adjusted, which will cause obvious cutter marks on the surface of the ingot and affect the surface quality.

[0008] In view of this, the present invention is proposed. Summary of the invention

[0009] In order to overcome the above-mentioned defects, the present invention provides a cyclone milling machine transmission mechanism, which has a simple and reasonable structure, is closer to actual working conditions, can effectively ensure the integrity, smoothness and processing quality of the ingot surface, and effectively reduce tool loss.

[0012] In addition, the structure for realizing the transmission connection between the transmission gear B and the milling cutter is as follows: the output transmission assembly further comprises a transmission gear D positioned and sleeved on the milling cutter, and the transmission gear D is meshingly connected with the transmission gear B.

[0013] As a further improvement of the present invention, the intermediate transmission assembly also has two counterweight shafts, and the two counterweight shafts are also positioned and installed on the base, and the two counterweight shafts are also evenly distributed around the axial center line of the connecting shaft together with the transition shaft.

[0018] As a further improvement of the present invention, a fixed support is provided, which is sleeved outside the connecting shaft and is locked and connected to the front side of the base at the same time. The fixed support also forms a receiving space together with the front side of the base to accommodate and restrain the fixed gear ring.

[0019] The beneficial effects of the present invention are as follows: ① The present invention optimizes the structure of the intermediate transmission component to change the processing mode of the milling cutter from "forward milling" to "reverse milling", which is closer to the actual working conditions, so that the teeth of the milling cutter will not collapse when cutting into the surface of the ingot, thereby ensuring the integrity and smoothness of the surface of the ingot; ② The intermediate transmission component designed by the present invention can effectively reduce the milling vibration and tool "creeping" and other undesirable phenomena caused by the gap in the transmission mechanism itself, thereby effectively reducing the tool loss, which not only prolongs the service life of the tool, but also reduces the cost loss; ③ The intermediate transmission component designed by the present invention can realize the adjustable ratio of the rotating body speed and the milling cutter speed, thereby effectively reducing the tool mark and improving the processing quality of the ingot surface, and is beneficial to improving the overall speed of the equipment and improving the processing efficiency; ④ Compared with the traditional structure, the modification amount of the transmission mechanism of the cyclone milling machine described in the present invention is small, which is conducive to processing implementation and has a very broad market application prospect.
