Description

Technical Field

[0001] The invention belongs to the field of machining machine tools, and in particular relates to an inclination angle adjustment mechanism for a tool. Background Art

[0002] With the development of aluminum electrolysis industry towards large-scale and the increasing requirements for energy conservation and consumption reduction, one of the important components used in the aluminum electrolysis industry is the anode conductive rod. The anode guide rod is a conductor used to connect the anode busbar and the anode steel claw of the electrolytic cell in the aluminum electrolysis process, and plays an important role in conducting electricity and suspending anode carbon blocks.

[0003] The aluminum busbar is the conductor for the current to enter and exit the electrolytic cell. The current is transmitted from the aluminum busbar to the anode guide rod through the contact surface. It sends high-power direct current, so that the high direct current passes through the electrolysis link from the positive electrode, and finally comes out from the electrolysis negative electrode to the rectifier cabinet. The aluminum busbar has high purity, low impurity content that affects conductivity, and good conductivity. The aluminum busbar can be up to 14 meters in length, with a maximum cross-sectional size of 550х250mm, and has small deviation, small bending and twisting, a flat surface, no ripples and cracks, a dense internal structure, no bubbles, slag inclusions and internal cracks, and is easy to install.

[0004] During the processing and production of aluminum busbars, the aluminum busbars will be chamfered at 40 and 45 degree angles according to customer needs. However, during the chamfering process of the aluminum busbars, it is necessary to use a tool to cut the four sides of the end of the aluminum busbar. The tools currently used include a connecting seat, a motor, and a blade connected to the output shaft of the motor. The motor is installed on a mounting base, one end of the mounting base is rotatably connected to the connecting seat, and the other end of the mounting base is connected to a cylindrical slider with a thread on the outer wall. The connecting seat is provided with an arc-shaped adjustment port for the position of the slider, and the slider is slidingly set in the adjustment port. The inclination angle of the blade is adjusted by sliding the slider. After determining the angle, a nut is used to lock the slider thread, so as to process aluminum busbars with different chamfering degrees. However, this method requires manual loosening and tightening of the nut to slide and lock the slider. The weight of the motor is generally large, and it also requires the cooperation of two people. Any slight deviation in the adjusted degree will affect the processing accuracy. Therefore, a marking pen is generally used for quick marking, and the deviation is reduced by observing the mark during the locking process of the slider. It can be seen that such a series of operations is relatively troublesome and inefficient, and in the entire process of adjusting the angle, the worker is close to the blade, which is very dangerous. Summary of the invention

[0005] The present invention aims to provide a tool inclination angle adjustment mechanism to solve the problems in the prior art of tool angle adjustment operation being complicated, inefficient and low in safety.

[0006] A tool inclination adjustment mechanism in the present scheme includes a connecting seat and a mounting seat for mounting the tool, one end of the mounting seat is rotatably connected to the connecting seat, and also includes a driving mechanism, the driving mechanism includes a motor, the output shaft of the motor is connected to a gear, and the motor is installed on the connecting seat; an adjustment plate is provided at the other end of the mounting seat, an arc surface is provided on the adjustment plate, and a plurality of adjustment teeth are evenly distributed along the arc direction on the arc surface, and the gears are meshed with the adjustment teeth.

[0007] The working principle of the present invention is: in the process of the gear being driven to rotate by the motor, the gear is exchanged between the adjusting teeth, and the adjusting teeth are used to transmit the mounting seat to rotate, and the angle of the tool connected to the mounting seat changes, thereby realizing the adjustment of the tool angle.

[0008] The beneficial technical effects of the present invention are:

[0009] 1. Mechanical adjustment is more automated and convenient than manual adjustment, achieving the effect of fast and efficient adjustment.

[0010] 2. The gear and the adjusting tooth are meshed and have a self-locking function. Once the angle is determined, the tool can stably maintain the adjusted angle.

[0011] 3. During the angle adjustment process, workers do not need to get close to the tool, which significantly improves safety.

[0012] Furthermore, the arc surface faces the tool. When the arc surface faces the tool, the motor is relatively closer to the tool, so that the structure of the adjustment mechanism is compact and the stability is better.

[0013] Furthermore, the connecting seat is provided with an arc-shaped adjustment opening, the adjustment opening is cocentric with the arc-shaped surface, a slider is slidably arranged in the adjustment opening, and the slider is connected to the mounting seat. Increasing the connection points between the connecting seat and the mounting seat makes the connection relationship between the mounting seat and the connecting seat more stable.

[0014] Furthermore, the edges of the adjustment opening are evenly distributed with angle lines, and the slider is provided with an angle needle pointing to the angle line. The angle line is designed by calculation, and when the angle needle coincides with the angle line, it indicates that the tool has turned to the required angle, which improves convenience.

[0015] Furthermore, the rotational connection between the mounting seat and the connecting seat is connected via a shaft, a bearing is provided on the shaft, an axial hole is provided on the connecting seat, and an outer ring of the bearing is fixed in the axial hole.

[0016] Furthermore, a retaining frame is fixedly connected between the end of the mounting seat away from the tool and the shaft, and the retaining frame and the mounting seat are respectively located on both sides of the connecting seat. The retaining frame strengthens the tightness between the mounting seat and the connecting seat, and the stability is further improved. BRIEF DESCRIPTION OF THE DRAWINGS
