Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, specifically to a transmission structure for a milling and turning composite machine tool. Background Technology

[0002] As modern manufacturing moves towards higher precision, higher efficiency, and greater flexibility, traditional single-function machine tools can no longer meet the demands. The increasing complexity of parts in industries such as automotive, aerospace, and precision electronics necessitates the completion of multiple machining processes on a single machine tool, leading to the emergence of mill-turning composite machine tools. Their transmission mechanisms, as a core component, also require continuous innovation and development to adapt to new machining requirements.

[0003] Composite machining is an important development trend in the field of machining. Mill-turn machining integrates multiple machining processes such as turning and milling. To achieve the coordinated operation of these different processes, the transmission mechanism needs to have more complex motion transmission and control capabilities to ensure precise relative movement between the tool and the workpiece, thereby improving machining efficiency and accuracy.

[0004] A mill-turning machine tool is a high-efficiency machining equipment that integrates turning and milling functions. Its transmission structure directly affects machining accuracy and efficiency. Traditional mill-turning machine tools typically use multi-stage gear transmission systems, which suffer from problems such as long transmission chains, high energy loss, high noise, and complex maintenance. Furthermore, traditional structures struggle to achieve high-precision synchronous control, affecting the machining quality of complex parts. Therefore, there is an urgent need to improve the transmission structure of mill-turning machine tools to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a transmission structure for a turning-milling composite machine tool to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transmission structure for a milling and turning composite machine tool, comprising a lathe body, a protective door movably mounted on the side of the lathe body, a machining space provided inside the lathe body, a turning fixture provided in the machining space, a protective cover fixedly mounted on the lathe body, a first guide rail fixedly mounted on the top of the lathe body, a second guide rail movably mounted at the end of the first guide rail, a control motor provided at the connection between the first guide rail and the second guide rail, a gripper fixedly mounted at the end of the second guide rail, and a control host fixedly mounted on the front of the lathe body.

[0007] Preferably, the machining space is equipped with a mounting base. The mounting base, as the basic support component of the machine tool, plays a crucial role in stabilizing the entire machining system. Inside, guide grooves are carefully designed. These guide grooves are symmetrically distributed above the mounting base, not only providing precise guidance for other moving parts and ensuring their smooth operation, but also enhancing the stability and symmetry of the structure, thereby improving the overall machining accuracy of the machine tool.

[0008] Preferably, the guide groove of the mounting base is provided with a waste outlet at the middle position. This waste outlet design is extremely ingenious. Under the action of gravity and cutting fluid, the debris and other waste generated during turning and milling can be collected along the guide groove to the waste outlet in the middle. It can clean up the waste in time, avoid the accumulation of waste affecting the processing, ensure the continuity and stability of the processing, and facilitate the unified collection and treatment of waste in the future.

[0009] Preferably, a spindle box is fixedly mounted on top of the mounting base. The spindle box is one of the core components of the machine tool, and it houses the spindle. A driven pulley and a turning fixture are fixedly mounted at both ends of the spindle, respectively. The driven pulley is driven by a belt to the motor pulley. The motor drives the motor pulley, which transmits power to the driven pulley via the belt, thereby driving the spindle to rotate at high speed. The turning fixture can securely clamp the workpiece, achieving efficient turning operations.

[0010] Preferably, a second slide rail is provided above the waste outlet. The second slide rail provides a track for the movement of specific components, ensuring their precise and stable movement. A telescopic component is provided at the right end of the second slide rail. This telescopic component can flexibly adjust the position of the components related to the second slide rail according to processing requirements, meeting the adjustment requirements of component positions under different processing conditions, and enhancing the processing adaptability and flexibility of the machine tool.

[0011] Preferably, slide rail one is located above slide rail two. Slide rail one further expands the movement dimension of the machine tool, and a milling fixture is located above it. The milling fixture can firmly clamp the milling tool. Under the coordinated action of slide rail one, slide rail two and related drive mechanisms, the milling fixture can drive the tool to move precisely, realize the milling process of the workpiece, and cooperate with the turning function to complete the combined turning and milling machining of complex parts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The transmission structure of this milling-turning machine tool, through belt drive, offers significant advantages over traditional gear drives. Belt drive, relying on its excellent elasticity, effectively buffers vibrations and impacts during milling and turning, protecting machine tool components and extending their service life. It also significantly reduces operating noise, creating a quieter workshop environment. Its overload slippage characteristic protects other components under excessive loads. Furthermore, the simple structure of belt drive simplifies installation and maintenance, reducing both difficulty and cost. These advantages make belt drive play a crucial role in milling-turning machine tools.

[0014] 2. This milling-turning composite machine tool features a telescopic transmission structure that combines turning and milling operations, offering numerous advantages. Firstly, it significantly improves machining efficiency, allowing turning and milling operations to be completed in a single setup, reducing workpiece turnaround time, avoiding positioning errors caused by multiple setups, and enabling efficient machining of complex parts. Secondly, it greatly enhances the machine tool's machining flexibility. Facing workpieces of different shapes and process requirements, the telescopic structure can flexibly switch between turning and milling modes to meet diverse production needs. Furthermore, this integrated design reduces the overall footprint of the machine tool, lowers equipment investment costs for enterprises, optimizes workshop space layout, and injects new vitality into the development of the machining industry.
