Description

Technical Field

[0001] This utility model belongs to the field of metal ingot processing equipment, specifically relating to an integrated turning and boring machine. Background Technology

[0002] Metal ingots are formed by casting molten metal. Their internal structure is controlled by the casting process. During casting, the molten metal gradually forms and grows grains as it solidifies, resulting in a typically uniform microstructure. This uniformity improves the stability and reliability of the metal material, ensuring good mechanical properties. Cylindrical metal ingots are a common structural form. During production, their outer and inner surfaces need to be machined to remove defect layers near the surface, preparing them for the next extrusion process. Existing cylindrical metal ingots present the following problems during processing:

[0003] 1. In the current process of processing cylindrical metal ingots, different processing equipment is required to process the outer circle and inner hole of the metal ingots separately. The processing operation is complicated, the processing efficiency is low, and the processing cost of enterprises is high.

[0004] 2. When different equipment is used to process the outer circle and inner hole of a metal ingot separately, the positioning of the metal ingot is prone to deviation, which will cause the outer circle and inner hole of the processed cylindrical metal ingot to be out of axis, affecting the subsequent use of the metal ingot.

The method consists of multiple boring bars connected together to reduce costs and increase strength. A retractable boring head 43 is provided on the boring bar body 42 near its end. The retractable boring head 43 can realize the broaching machining method. The so-called broaching machining means that the boring tool first passes through the inner hole of the workpiece and then retreats along the original path.

When it first passes through the inner hole of the workpiece, the boring tool retracts into the boring bar to avoid contact with the inner hole of the workpiece. When it retreats along the original path, the boring tool expands out from the inside of the boring bar until the required inner hole diameter is reached, and then the inner hole is machined.

During the machining of the outer diameter, the external external cylindrical tool holder transmission (drive) mechanism drives the external cylindrical tool holder housing 61 to move along the axial direction of the workpiece to complete the machining of the entire outer surface of the workpiece. During installation, the outer side of the external cylindrical tool holder housing 61 is mounted on the V-shaped guide rail 17 and the flat rail 16. A machining cavity is provided inside the outer circular tool holder housing 61.

The drive arm assembly is connected to the second clamping arm assembly through the second connecting rod and drives the second clamping arm assembly to achieve the clamping action.

[0038] The working process of this integrated turning and boring machine is as follows:

[0039] Step 1: Loading and Unloading

[0040] During loading, a cylindrical workpiece is transported to the top of the turning and boring machine using manual or automatic methods such as a robotic arm or overhead crane. Based on the pre-input workpiece length, the moving centering mechanism 7 and the outer cylindrical tool holder move to preset positions, positioning the moving centering mechanism 7 and the fixed centering mechanism 64 at opposite ends of the workpiece. The clamping arms and drive arms of the moving centering mechanism 7 and the fixed centering mechanism 64 open, the robotic arm or overhead crane lowers the workpiece, and releases it, allowing it to fall into the moving centering mechanism 7 and the fixed centering mechanism 64. At this point, the clamping arms and drive arms clamp the workpiece. Through design and installation, after the cylindrical workpiece is clamped by the moving centering mechanism 7 and the fixed centering mechanism 64, its axis coincides with the axis of the chuck device (chuck device I24, chuck device II33) on the fixed head frame component 2 and the moving tail frame component 3. This is to ensure that the workpiece rotates smoothly during processing, avoid danger, and at the same time ensure the concentricity of the outer circle and inner hole of the processed workpiece. When unloading, the robot or overhead crane first grabs the workpiece, and then the clamping arm and drive arm of the moving centering mechanism 7 and the fixed centering mechanism 64 open, so that the robot or overhead crane can take away the workpiece.

[0041] Step 2: Centering and clamping the workpiece

[0042] In step one, the workpiece falls into the moving centering mechanism 7 and the fixed centering mechanism 64. The two centering mechanisms (centering clamping mechanism 73 and fixed centering mechanism 64) lift the workpiece, and each centering mechanism centers the workpiece at three points. Then, the moving tail frame component 3 moves forward, and the chuck device II33 on the moving tail frame component 3 holds one end of the workpiece, driving the workpiece forward until the other end of the workpiece contacts the chuck device I24 on the fixed head frame component 2. Then, the two chuck devices (chuck device I24 and chuck device II33) clamp the workpiece, and the two centering mechanisms release, completing the positioning of the workpiece.

[0043] Step 3: Boring and Carcass

[0044] Select a boring head of appropriate size (the boring head is set at the front end of the boring tool, and several cutting tools are mounted on the boring head. The outer circle where the cutting edge of the cutting tool is located is the size of the inner hole to be bored). At this time, the boring support device 5 moves forward, and the support rod body 52 in the boring support device 5 passes through the hole inside the workpiece (the hole is present during casting and is relatively rough, so it needs to be trimmed by boring). At the same time, the tool bar (the left tool bar 62 and the right tool bar 63 have the same structure and are both driven by a servo motor) moves forward to the appropriate position under the drive of the servo motor behind it. At this time, the distance between the cutting edges at the front end of the two tool bars is the size of the outer diameter of the workpiece after machining.

[0045] Step 4: Processing

[0046] When the main motor 22 in the fixed head frame component 2 is turned on, the main motor 22 drives the pulley I25 to rotate through the motor output shaft. The pulley I25 is connected to the pulley II26 through the belt and drives the pulley II26 to rotate. When the pulley II26 rotates, it drives the drive shaft assembly 23 to rotate. The drive shaft assembly 23 drives the workpiece and the passive shaft assembly 32 on the moving tail frame component 3 to rotate through the chuck device I24. At this time, the outer cylindrical tool holder (left tool bar 62, right tool bar 63) begins to move along the axial direction of the workpiece to process the outer surface of the workpiece. The boring head and boring bar support device at the front end of the boring tool move synchronously along the axial direction of the workpiece to process the inner surface of the workpiece.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
