Description

Technical Field

[0001] This utility model relates to the field of composite machine tool technology, specifically a power turret turning and milling composite machine tool. Background Technology

[0002] In fields such as precision machining and automotive parts manufacturing, power turret milling and turning composite machine tools are core equipment for achieving multi-process integrated machining. However, traditional models have gradually revealed problems in practical applications, such as the difficulty in balancing machining accuracy and efficiency. The lifting and adjusting systems of traditional machine tools mostly use a single cylinder drive, lacking a stable guiding structure. This causes the electric cutting head to easily deviate and wobble during vertical movement. Especially when machining large-sized or high-hardness workpieces, the vibration caused by the cutting force further amplifies the positional deviation, ultimately affecting the dimensional accuracy and surface finish of the workpiece. This makes it difficult to meet the machining requirements of high-precision parts in fields such as aerospace and new energy vehicles.

[0003] Meanwhile, traditional machine tool workpiece positioning systems have significant limitations. Some models only have unidirectional movement adjustment capabilities, requiring multiple clamping operations to complete multi-station machining of the workpiece. This not only increases manual operation costs but also generates cumulative errors due to repeated clamping. Even if some models support bidirectional movement, the structural designs of their lateral and longitudinal movement devices differ significantly, resulting in inconsistent transmission ratios and positioning accuracy. This can easily lead to positioning deviations of the workpiece in the horizontal plane, especially for complex workpieces with irregular contours or multiple holes, making it difficult to achieve accurate full-range positioning and hindering processing efficiency and product qualification rates.

[0004] Furthermore, there is room for improvement in the clamping devices of traditional machine tools. Most clamping devices use a single thread to drive the movement of a single clamping block. During clamping, the two clamping blocks move asynchronously, which can easily lead to workpiece displacement or uneven force, resulting in workpiece deformation. Moreover, the clamping blocks are mostly made of high-strength metal, which, when in direct contact with the workpiece, can easily cause scratches and indentations on the surface of soft materials such as aluminum alloys and copper, affecting the surface quality of the workpiece. These problems not only reduce the machining adaptability of the machine tool but also increase the cost of subsequent surface treatment processes, making it difficult to meet the comprehensive requirements of modern manufacturing for efficient, high-precision, and low-damage machining.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figure 1-3 As shown in the figure, an embodiment of the present invention provides a power turret milling and turning composite machine tool, including a machine tool frame 1. A telescopic cylinder 2 is fixedly installed on the machine tool frame 1. A telescopic frame 3 is fixedly connected to the output end of the telescopic cylinder 2. A slider 4 is fixedly connected to the side wall of the telescopic frame 3. The slider 4 is slidably connected to a slide rail 5. An electric cutting head 6 is installed on the telescopic frame 3. When the telescopic cylinder 2 provides lifting power, the sliding of the slider 4 along the slide rail 5 can limit the movement trajectory of the telescopic frame 3, preventing it from deviating or swaying during lifting and lowering, and ensuring that the electric cutting head 6 always adjusts its height stably in the vertical direction.

[0025] This linkage can precisely control the vertical distance between the electric cutting head 6 and the workpiece, adapt to the processing requirements of workpieces of different sizes, and at the same time ensure the positional stability of the electric cutting head 6 during the cutting process, thereby improving the processing accuracy.

[0026] A transverse moving device 7 is installed on the machine tool frame 1. The transverse moving device 7 includes a frame 71 fixedly connected to the machine tool frame 1. A drive motor 72 is fixedly installed at one end of the frame 71. The drive motor 72 is connected to a drive screw 74 through a drive assembly 73. The screw 74 is threadedly connected to a screw block 75. The screw block 75 is fixedly connected to a longitudinal moving device 8 on its upper part. A clamping device 9 is fixedly connected to the upper part of the longitudinal moving device 8. The clamping device 9 includes a clamping seat 91. A servo motor 92 is fixedly connected to one end of the clamping seat 91. A counter-screw 93 is fixedly connected to the output end of the servo motor 92. A clamping block 94 is threadedly connected to the counter-screw 93.

[0027] It achieves precise positioning of the workpiece in the entire horizontal plane. Through independent adjustment and linkage between the horizontal and vertical directions, the workpiece on the clamping device 9 can be moved to any processing position to meet the multi-station processing needs of complex-shaped workpieces.

[0028] During the linkage process, the threaded engagement between the screw 74 and the screw block 75 has self-locking properties. Combined with the stable transmission of the drive component 73, it can prevent the workpiece from being displaced due to cutting force during processing, thus ensuring the dimensional accuracy of the processing.

[0029] The working principle of this power turret milling and turning composite machine tool is as follows: Before machining, the workpiece to be machined is placed on the clamping seat 91 of the clamping device 9. The servo motor 92 starts and drives the opposing screw 93 to rotate. Because the opposing screw 93 has two opposite threads, the threaded clamping blocks 94 will move closer to each other, and the workpiece is clamped and fixed by the front fixing block 95. Subsequently, if it is necessary to adjust the lateral position of the workpiece, the drive motor 72 of the lateral moving device 7 drives the screw 74 to rotate through the drive assembly 73 including the wheel and belt, so that the threaded screw block 75 moves along the screw 74, thereby driving the workpiece to rotate. The upper longitudinal moving device 8 and the clamping device 9 move laterally as a whole. Since the structure of the longitudinal moving device 8 is the same as that of the lateral moving device 7, it can drive the clamping device 9 to move longitudinally through its own driving components, so as to achieve precise positioning of the workpiece in the horizontal direction. At the same time, the extension cylinder 2 on the machine tool frame 1 drives the extension frame 3 connected to the output end to rise and fall. The extension frame 3 slides stably along the slide rail 5 on the side wall of the machine tool frame 1 through the side wall slider 4, so that the electric cutting head 6 on the extension frame 3 is adjusted to a suitable height. Finally, the electric cutting head 6 performs turning, milling and other machining operations on the positioned workpiece.

[0030] like Figure 1 As shown, in some embodiments, the slide rail 5 is fixedly installed on the side wall of the machine tool frame 1; when the extension cylinder 2 drives the extension frame 3 to rise and fall, the slider 4 slides along the slide rail 5, which can strictly limit the movement trajectory of the extension frame 3, avoid the extension frame 3 from shifting left and right, swaying or tilting during vertical movement, and ensure that the extension frame 3 always maintains stable vertical movement, providing precise guidance for the height adjustment of the electric cutting head 6.

[0031] like Figure 2 As shown, in some embodiments, the drive assembly 73 includes two discs and a belt for connecting the two discs, with the belt driving the discs; when the lateral moving device 7 needs to drive the workpiece to move laterally, the drive motor 72 starts and drives the disc on its output shaft to rotate, and the disc drives another disc connected to the screw 74 to rotate synchronously through the friction of the belt, thereby causing the screw 74 to rotate accordingly.

[0032] like Figure 1As shown, in some embodiments, the structure of the longitudinal moving device 8 is the same as that of the transverse moving device 7, and they are arranged in a cross configuration. The same structure, especially the matching accuracy of the screw 74 and the screw block 75, and the transmission ratio of the drive component 73, ensure that the moving accuracy of the longitudinal moving device 8 and the transverse moving device 7 is consistent, such as positioning error and repeat positioning error. This avoids deviation in the horizontal positioning of the workpiece due to the difference in accuracy between the two, and ensures the dimensional accuracy of the subsequent processing by the electric cutting head 6.

[0033] like Figure 3 As shown, in some embodiments, the opposing screw 93 is provided with two sections of threads with opposite directions; when the servo motor 92 drives the opposing screw 93 to rotate, the two sections of reverse threads will generate axial driving forces in opposite directions on the two clamping blocks 94.

[0034] like Figure 3 As shown, in some embodiments, a fixing block 95 is fixedly connected to the front end of the clamping block 94. In milling and turning machining, the surface quality of the workpiece, such as smoothness and flatness, is an important machining indicator. The fixing block 95 can be made of a material with a lower hardness than the workpiece, such as wear-resistant rubber, engineering plastics, or soft metal. When in contact with the workpiece, it can prevent the clamping block 94, which is usually made of high-strength metal, from directly squeezing and scratching the workpiece surface. Especially for soft materials such as aluminum alloys and copper, it can effectively reduce surface indentations, scratches, and other damage, thus balancing clamping function and workpiece surface quality protection.

[0035] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
