Technical Field

[0002] In the intelligent manufacturing equipment industry, a turning-milling composite machine tool is a combined processing equipment that integrates multiple processing functions such as turning and milling, and is particularly suitable for the processing of different metal materials. Its core value lies in achieving multi-process machining of complex parts through one-time clamping and composite machining.

[0003] In the existing published literature, the patent with the patent publication number CN104139304A discloses a turning-milling composite machine tool. In this technology, the milling saddle can drive the column and the milling slide plate to move along the axial direction of the spindle unit, the column can drive the milling slide plate to move along the first radial direction of the spindle unit, and the milling slide plate can move along the second radial direction of the spindle unit. The first radial direction is perpendicular to the second radial direction. However, this technology has the following defects.

[0004] In the intelligent manufacturing equipment industry, the combined machining of turning-milling composite machine tools faces challenges in terms of efficiency and accuracy. For different tools, the traditional operation requires first switching the tool to set the origin, then moving to the curved path position, and then replacing another tool to repeat this process. However, when processing a curved stepped route, since each tool needs to accurately machine according to the curved stepped turning-milling position, it is difficult for the traditional technology to ensure that multiple different tools perform precise synchronous operations according to the preset curved stepped inclination positions. This process not only results in low combined machining efficiency but also significantly reduces the machining accuracy due to multiple tool setting and path adjustment. Summary of the Invention

The door body 34 is slidably connected to the machine body 1.

[0034] The working principle of the present invention in combination with the hydraulic center frame turning-milling compound machine tool is as follows:

[0035] Step 1: During installation, insert the workpiece 26 into the inner wall of the three-jaw chuck 27 and clamp the workpiece 26 through the three-jaw chuck 27. Then, the hydraulic cylinder 30 pushes the center frame 29 to move. Since the hydraulic cylinder 30 is a prior art and its hydraulic principle will not be described in detail, it belongs to the existing public technology. The center frame 29 drives multiple rollers 33 to be positioned on the outer wall of the workpiece 26. At the same time, the machine body 1 supports the housing 31, the housing 31 supports the hydraulic cylinder 30, and the center frame 29 hydraulically moves to the outer wall of the workpiece 26. Meanwhile, the multiple rollers 33 can perform stable positioning operations on the outer wall of the workpiece 26, and thus cooperate with the center frame 29 for composite machining. Then, pull the door body 34 to the right, and the door body 34 closes the machine body 1.

[0036] Step 2: When performing curvilinear path positioning and movement, start the moving electric cylinder 23 through the controller 32. The moving electric cylinder 23 drives the moving block 22 to move leftward, the moving block 22 drives the moving bar 21 to move leftward, the moving bar 21 drives the frame plate 20 to move leftward, the frame plate 20 drives the sliding rod 18 to move leftward, the sliding rod 18 makes the two sliding rings 19 move leftward. At the same time, the sliding rod 18 drives the linkage support block 17 to move leftward, and the linkage support block 17 makes the sliding sleeve block 4 move leftward. The sliding sleeve block 4 moves along the outer wall of the curve guide rail 3 in a curvilinear motion. Meanwhile, the sliding rod 18 slides inside the frame plate 20, and the two sliding rings 19 slide on the frame plate 20.

[0037] Step 3: During combined machining, drive the three-jaw chuck 27 to rotate through the transmission motor 28, and the three-jaw chuck 27 drives the workpiece 26 to rotate at a high speed. When the sliding sleeve block 4 moves along the outer wall of the curve guide rail 3 in a curvilinear path, the sliding sleeve block 4 drives the inclined groove seat 5 to move in a curvilinear path, the inclined groove seat 5 drives the first-order tool holder 7 to move in a curvilinear path. At the same time, the inclined groove seat 5 drives the second-order tool holder 9 to move in a curvilinear path, and the inclined groove seat 5 can also drive the third-order tool holder 11 to move in a curvilinear path. In this way, the first-order tool holder 7 drives the tip tool 8 to move in a curvilinear path, the second-order tool holder 9 drives the corner tool 10 to move in a curvilinear path, and the third-order tool holder 11 drives the turning and milling groove tool 12 to move in a curvilinear path. Sense the distance between the moving electric cylinder 23 and the second distance sensor 24 through the second distance sensor 24. When the distance value sensed by the second distance sensor 24 is the same as the distance value set by the controller 32, then close the moving electric cylinder 23 through the controller 32. In this way, the tip tool 8, the corner tool 10, and the turning and milling groove tool 12 all move to the precise intelligent position synchronously along the curvilinear path.

[0038] Meanwhile, the tilting cylinder 15 is started through the controller 32. The tilting cylinder 15 causes the linkage block 14 to tilt and move along the inner wall of the tilting groove base 5. The linkage block 14 drives the linkage bar 13 to tilt and move. The linkage bar 13 drives the tilting plate 6 to move. The tilting plate 6 causes the first-order tool holder 7 to tilt and move. The first-order tool holder 7 drives the tip tool 8 to tilt and move. At the same time, the tilting plate 6 drives the second-order tool holder 9 to tilt and move. The second-order tool holder 9 causes the corner tool 10 to tilt and move. At the same time, the tilting plate 6 drives the third-order tool holder 11 to tilt and move. The third-order tool holder 11 drives the turning and milling groove tool 12 to tilt and move. In this way, the tip tool 8, the corner tool 10, and the turning and milling groove tool 12 contact the workpiece 26 at the stepped tilting positions. The generated chips will be blocked and protected by the baffle 25, and the workpiece 26 can be subjected to turning and milling combined processing at high speed. At the same time, the workpiece 26 drives a plurality of rollers 33 to roll, and the rollers 33 roll stably inside the center frame 29. The distance between the linkage block 14 and the first distance sensor 16 is sensed by the first distance sensor 16. When the distance value sensed by the first distance sensor 16 is the same as the distance value set by the controller 32, the tilting cylinder 15 is closed by the controller 32. In this way, precise synchronous operation of the preset curve stepped tilting positions of different tools can be performed on the workpiece 26, which not only makes the combined processing efficiency higher, but also reduces the number of tool setting and path adjustment, and significantly improves the processing accuracy.
